As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

In one embodiment, the chip removal device comprises a shell, a driving piece, a chip removal assembly and a cleaning assembly, wherein the chip removal assembly and the cleaning assembly are arranged in the shell; the chip removal port is positioned between the chip removal assembly and the cleaning assembly; driving piece fixed mounting be in the side of casing and with the chip removal subassembly rotates to be connected, the chip remover subassembly includes the broach scraping plate, the driving piece drive the chip remover subassembly is followed casing rotary motion, the clearance subassembly is in chip removal department is right the broach scraping plate is cleared up.

The chip removal assembly is provided with a comb tooth chip scraping plate, and bulk chips or strip chips can be fixed and wound through comb teeth and then conveyed and discharged; the cleaning assembly at the chip removal opening can clean up the cuttings on the comb teeth, the cuttings on the comb teeth are prevented from winding the comb teeth, and the cuttings are not smoothly removed. And when the cuttings are wound around the comb teeth, the fine cuttings can be mixed between the bulk cuttings and the bottom of the shell and discharged along with the comb teeth, so that mixed cuttings are discharged.

Referring now to fig. 1 and 2, a chip removal device including a housing 100, a driving member, a chip removal assembly 200 disposed within the housing, and a cleaning assembly 300 will be described in conjunction with an exemplary embodiment to further understand the concept of the chip removal device. Specifically, the housing 100 includes a lifting portion and two horizontal portions, and the lifting portion is connected to the two horizontal portions end to form the illustrated pattern. The housing is provided with a guide rail matching the shape of its path, wherein the guide rails of the bottom horizontal portion and the lifting portion are provided independently of the guide rails of the upper horizontal portion. A chip removal port 101 is provided below a position where the upper horizontal portion is connected to the lifting portion. The chip removal assembly 200 and the cleaning assembly 300 are located on either side of the exhaust port. The driving piece adopts gear motor 400, and its fixed mounting is in one side of casing to the output shaft rotates with the chip removal subassembly and is connected. When the speed reducing motor rotates, the chip removal assembly can be driven to rotate along the guide rail of the shell. Further, the chip cleaner subassembly includes broach scraping plate 201, and when gear motor drove broach scraping plate 201 and moved to the chip removal mouth, the clearance subassembly cleared up broach scraping plate.

In one embodiment, the cleaning assembly can also be designed as a comb-tooth scrap scraping plate and is fixed at one end of the upper horizontal part close to the scrap discharging port, the comb teeth are arranged towards the scrap discharging assembly, and when the scraps conveyed by the scrap discharging assembly reach the scrap discharging port, the comb teeth arranged on the cleaning assembly scrape the scraps on the scrap discharging assembly; the cleaning assembly can also be arranged into a clamp with an opening and closing device, and the chip on the chip removal assembly can be cleaned through the opening and closing of the clamp at the chip removal opening.

Therefore, the comb-tooth scrap scraping plate can insert and fix the bulk cuttings or the strip cuttings through the comb teeth or enable the cuttings to be wound in the comb teeth for feeding, conveying and discharging, so that the cuttings are prevented from being wound due to movement in the conveying process; and the cleaning assembly can clean the cuttings on the comb teeth at the positions of the cuttings outlets, and the problem that the cuttings on the comb teeth are wound around the comb teeth to cause the reverse belts of the cuttings or the unsmooth cuttings removal is avoided. And when the cuttings are wound around the comb teeth, the fine cuttings can be mixed between the bulk cuttings and the bottom of the shell and discharged along with the comb teeth, so that the mixed conveying of the cuttings and the bulk cuttings is realized.

It should be noted that the outer shape of the housing 100 may be configured according to the space of the machine tool, for example, the housing may be designed as shown in fig. 3, as long as the chips can be discharged, and the present application is not particularly limited.

In one embodiment, to reduce the cost of the chip ejector device, the chip ejection assembly includes a conveyor belt running on a guide rail in the housing, and a comb chip scraper fixed to the conveyor belt. In another embodiment, in order to facilitate the observation or maintenance of the chip discharging device and to improve the conveying efficiency of the chip discharging device, it is preferable that the chip discharging assembly 200 includes two conveying chains 202, which are respectively engaged with the corresponding guide rails on both sides of the housing and are connected end to end. The comb scrap scraping plate is fixedly connected with the two conveying chains. The lifting part is provided with a transmission shaft at one end close to the cleaning assembly, chain wheels are arranged at two ends of the transmission shaft, and the chain wheels are meshed with the conveying chains at two sides. The gear motor is fixed in the outside of promotion portion and the output is connected with the transmission shaft. The speed reducing motor acts to drive the comb tooth scrap scraping plate to work.

The application scheme solves the defects that the traditional chain plate and chain plate is high in cost and incapable of conveying scraps, and solves the hidden danger that the scraper chip cleaner is wound by long chips.

It should be noted that, in order to guarantee the conveying efficiency, a plurality of comb scraping plates can be arranged and installed on the conveying chain at intervals. Preferably, the conveyor chain is a multi-pitch chain with accessories, e.g. one accessory at six pitches. The comb scrap scraping plate is in threaded connection with accessories on the chain through bolts. Like this, the installation and the dismantlement of broach scraping bits board are convenient, owing to leave the space between every broach scraping bits board moreover, so the smear metal that drops in the casing can directly fall into the casing bottom and in time discharge, avoids producing to pile up or the extrusion.

In one embodiment, the cleaning assembly can be driven by another speed reducing motor for dynamically cleaning the chips on the comb-type chip scraper of the chip removal assembly. Specifically, referring to fig. 2, the speed reduction motor is fixedly installed on one side surface of the housing, an output shaft of the speed reduction motor is rotatably connected with the cleaning assembly, the speed reduction motor drives the cleaning assembly to perform rotary motion along a guide rail in the housing, and the operation direction of the speed reduction motor is opposite to that of the chip removal assembly. The cleaning assembly rotates reversely, so that continuous cleaning can be realized, and the cleaning efficiency is improved; and if chips wound on the cleaning assembly are easy to fall off in the rotating process, the cleaning effect is better.

It should be noted that, in order to better clean the chips by the cleaning assembly, a through opening is arranged below the cleaning assembly in the shell, the through opening is communicated with the chip removal port, and the size of the through opening is matched with that of the cleaning assembly. Thus, when the cleaning assembly works, the cutting chips are not completely fallen off at the chip outlet, and can be separated from the cleaning assembly at the opening below the cleaning assembly along with the rotation of the cleaning assembly and fall off.

In one embodiment, in order to simplify the structure of the cleaning assembly and facilitate installation and maintenance, the cleaning assembly comprises two conveying chains and a cleaning plate. Specifically, the conveying chain can adopt a multi-pitch conveying chain with accessories, the multi-pitch conveying chain is arranged on a corresponding guide rail in the shell, and the cleaning plate is fixedly arranged on the accessories of the two conveying chains. One end of each conveying chain can be provided with a transmission shaft and a chain wheel, the transmission shafts penetrate through the shell, the chain wheels are embedded into two ends of the transmission shafts and located in the shell, the two conveying chains are respectively meshed with connecting wheels at the two ends, and the speed reduction motor is connected with one end of each transmission shaft. And the cleaning plate is driven to rotate along the horizontal part on the upper part of the shell by the speed reducing motor, so that the chips on the comb-tooth chip scraping plate are dynamically cleaned.

In one embodiment, in order to clean thoroughly and also to achieve better cleaning effect, a plurality of slits are arranged on the cleaning plate, so that the cleaning plate forms a plurality of narrow strips. The gap of clearance board corresponds the matching with the broach of broach scraping plate, that is to say the broach of broach scraper blade can pass the gap of clearance board, and the broach on the broach scraping plate is misplaced with the narrow strip on the clearance board. Like this, during the design, the position that clearance subassembly and chip removal subassembly can be close, that is to say that the clearance plate can imbed the broach scraping plate (the two dislocation is crossing, has the coincidence), and the broach scraping plate can be combed the root of broach scraping plate similar to comb structure, and the scope of clearance is bigger, more clean, thorough of clearance.

In one embodiment, the chip removal assembly further includes a flat scraper 203 for more thoroughly cleaning the interior of the housing of finely divided chips. When the comb-tooth scraping plates convey the lump chips, part of the chips can fall off from gaps of the comb teeth, and the flat scraping plates can discharge the part of the escaped fine chips. Optimally, the flat scraping plate and the comb scraping plate are arranged adjacently, so that when the scraps are discharged, the scraps can be discharged in time, and accumulation is avoided. The two scraping plates are matched for use, so that the conveying effect is better.

The flat scraping plate and the comb scraping plate have the same outer dimensions. And according to the actual operating condition, the sizes of the comb-tooth scraping plates and the flat scraping plates can be designed at will according to the cutting amount or the cutting size, particularly the height size (the distance from the conveying chain to the bottom of the shell).

It should be noted that the chip removal device may be provided with a control device, and when the cleaning assembly and the chip removal assembly are required to work normally and stably, the control device adjusts the operation speed and/or the operation time of the two speed reduction motors. The movement mode can be set according to the requirement, and if the cleaning assembly is adjusted to perform intermittent action or manually control starting and stopping according to time, the comb tooth scrap scraping plate and the cleaning plate meet at a scrap outlet, at the moment, the cleaning plate can clean the cuttings on the comb tooth scrap scraping plate, and the cuttings are prevented from being wound on the comb tooth scrap scraping plate and being reversely carried; the problem of collision between the cleaning assembly and the flat scrap scraping plate can be avoided.

Referring to fig. 2, in an embodiment, in order to reduce the cost of the chip removal device, simplify the structure and reduce the operation difficulty, a speed reduction motor can be used for the cleaning assembly and the chip removal assembly. In particular, the chip evacuation device further includes a drive assembly 500. The drive assembly comprises two drive sprockets 501 and a drive chain 502. Specifically, the transmission shafts in the chip removal assembly and the cleaning assembly protrude out of the shell at one end far away from the speed reducing motor, the protruding ends are respectively sleeved with the transmission chain wheels 501, and the transmission chain 502 is wound around the two transmission chain wheels and meshed with the two transmission chain wheels. At the moment, only one speed reducing motor is needed to be adopted and is in driving connection with the chip removal assembly or the cleaning assembly. When the speed reducing motor is started to drive any one of the chip removal assembly or the cleaning assembly to rotate, the cleaning assembly or the chip removal assembly can be driven through the driving wheel and the driving chain in the driving assembly. Therefore, the cleaning component and the chip removal component can move simultaneously by using one speed reducing motor, so that the manufacturing cost is reduced, and the control and operation modes are simplified.

It should be noted that in this embodiment, the optimal chip removal assembly is the same size as the sprocket and the conveying chain used in the cleaning assembly; the tooth number and the pitch of the two driving wheels 501 and the chain wheel are also the same, so that the cleaning assembly and the chip removal assembly can synchronously move (the rotating speed, the running speed and the like are the same) under the driving of the motor, and the control is more convenient.

In one embodiment, the cleaning plate in the cleaning assembly can adopt the same structure as the comb teeth scraping plate as long as the comb teeth of the cleaning plate and the comb teeth scraping plate are staggered, so that the design and the manufacture are simple and convenient. And in order to improve the conveying efficiency, a plurality of cleaning plates can be arranged. In order to avoid the problem of interference between the cleaning plates and the flat scraping plates, the plurality of cleaning plates are equally spaced and the spacing distance is even times of the spacing distance of the comb scraping plates. Therefore, when the comb-tooth scrap scraping plate is designed and installed, the cleaning plate also reaches the scrap discharging port and can be matched with the comb-tooth scrap scraping plate; when the flat chip scraping plate reaches the chip removal port, the cleaning assembly is not provided with the cleaning plate, and the flat chip scraping plate directly discharges conveyed chips from the chip removal port. Thus, only the comb scraping plate can work with the cleaning plate.

In one embodiment, referring to fig. 4, the comb scraping plate 201 comprises a connecting plate and comb teeth, wherein two ends of the connecting plate are in threaded connection with the conveying chain; the broach is set up the one side at the connecting plate by a plurality of circular or oval steel column interval array. One end of the steel column, which is far away from the conveying chain, is arranged to be a conical shape or a steel column with a conical size, and the conical size is gradually reduced along the direction of far away from the conveying chain, so that the steel column can be conveniently inserted into bulk cuttings, and the cuttings can easily fall off. And when the cleaning plate is crossed and converged, the taper size is easier to match, and the problems of interference and friction are avoided.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
