Technical Field

The invention belongs to the technical field of cutting machines, and particularly relates to a board square hole cutting machine.

Background

In carrying out carpenter's course of working, often need carry out the trompil on the plank, traditional processing method is that the manual work uses drilling tool to drill on the trompil position of plank earlier, uses cutting means to cut the trompil position neat again, and this method is nearer apart from the staff at the during operation, and danger is higher, causes personnel's injury easily, and efficiency is very low moreover.

Application No. 201710566360.1's application document discloses a drilling equipment for gear machining and method of punching thereof, though it is used for drilling equipment for gear machining, but the structure thinking of an extremely processing square hole has been designed, be about to make square hole mechanism and round hole mechanism set up together, it is rotatory through a driving motor drive, first cylinder drive makes square hole mechanism and round hole mechanism downstream, thereby can beat round hole and square hole, this technical scheme can improve machining efficiency greatly, avoid personnel's safety problem simultaneously.

Application number 201910667555.4 also discloses a plank square hole cutting machine, and the cutting machine of this application is including first support, arc slide rail, first slider, second support, the first in command, carriage release lever etc.: arc-shaped sliding rails are symmetrically arranged at the front side and the rear side of the first support top in an embedded mode. Can keep apart first saw bit and second saw bit and staff through the second support that sets up, increase staff's safe distance, improve staff's personal safety's guarantee, the security is higher: can directly take off the billet of plank top hole department through the push jack that sets up, reduce the process that the staff removed the plank, reduce staff's work load, practice thrift staff's physical power, be favorable to staff's work.

The two applications respectively kilometer different cutting schemes, but aiming at the technical purpose of cutting the square holes of the wood boards, the technical scheme with the application number of 201910667555.4 is obviously more reasonable. However, the application needs to compensate and cut the two groups of cutting tools on the outer side through rotating and turning to complete the cutting of a square hole, and when a plate to be cut is too large, the obstacle in the rotating process can be caused, so that the hole opening requirement of a large plate cannot be completed.

Examples

A cutting table 200, a plate frame 300, wherein the cutting table 200 and the plate frame 300 are both fixedly mounted on the top of the base 100, and the cutting table 200 is arranged in the center of the base 100. A first cutting knife group 210 and a second cutting knife group 220 are arranged on the cutting table 200, and the first cutting knife group 210 and the second cutting knife group 220 are symmetrically arranged on the side wall of the cutting table 200; grillage 300 sets up two sets ofly altogether, and two sets of grillages 300 set up the symmetry and set up in the outside of cutting table 200, and feed motion is to grillage 300 direction to first cutting knife group 210 and second cutting knife group 220 homoenergetic, and this cutting table 200 can carry out the ascending rotation of perpendicular to base 100 axial.

During cutting, the plates are fixed in the vertical direction through two groups of plates, the two plates are arranged in the directions of the first cutting knife set 210 and the second cutting knife set 220, the first cutting knife set 210 and the second cutting knife set 220 are started, the first cutting knife set 210 and the second cutting knife set 220 are driven to respectively feed in opposite directions, two parallel cutting grooves are formed in the two plates, the first cutting knife set 210 is used for cutting out two parallel transverse cutting grooves, the second cutting knife set 220 is used for cutting out two parallel vertical cutting grooves, the cutting table 200 is controlled to rotate 180 degrees, cutting is repeated, and therefore the two plates with the square holes can be cut out simultaneously.

Because cutting table 200 is built-in, the panel that will treat the cutting is external to can avoid treating the too big influence of cutting panel size to cutting table 200 pivoted, cutting table 200 in this embodiment can freely transmit, can not receive the influence of treating the panel size of cutting, therefore can carry out the trompil to arbitrary size panel.

As shown in fig. 3, the cutting table 200 includes a fixed base 201 and a rotating table 202 coaxially disposed, a first servo motor 203 is installed in the fixed base 201, the rotating table 202 is rotatably connected to the fixed base 201 through a flat bearing, a protruding shaft column is disposed at the bottom of the rotating table 202, and the first servo motor 203 drives the shaft column to rotate through gear engagement. First servo motor 203 turns into turned angle through receiving pulse signal, can accurate control revolving stage 202 rotatory fixed angle, revolving stage 202 need rotate 180 in this application.

As shown in fig. 1 and 2, the first cutting knife set 210 includes a first dual shaft motor 211, first blades 212, and two sets of the first blades 212 are mounted on two output shafts of the first dual shaft motor 211; the second cutter group 220 includes a second dual-shaft motor 221 and second blades 222, and two sets of the second blades 222 are mounted on two output shafts of the second dual-shaft motor 221. The connection structure of the first cutting knife set 210 and the second cutting knife set 220 is identical, and only the positions of the first blade 212 and the second blade 222 are different, and the planes of the first blade 212 and the second blade 222 are perpendicular to each other, so that the square hole can be machined by matching the first blade 212 and the second blade 222.

As shown in fig. 4, the rotating platform 202 is further provided with a second servo motor 204, a first suspension arm 205 and a second suspension arm 206, an outer end of the first suspension arm 205 is fixedly connected with the first double-shaft motor 211, an outer end of the second suspension arm 206 is fixedly connected with the second double-shaft motor 221, the rotating platform 202 is provided with a chute for the first suspension arm 205 and the second suspension arm 206 to slide, the second servo motor 204 is installed inside the rotating platform 202, and the second servo motor 204 can drive the first suspension arm 205 and the second suspension arm 206 to move in the same direction/opposite direction through gear and rack meshing. When the second servo motor 204 is driven to work, after the driving gear mounted on the output shaft of the second servo motor 204 is meshed with the racks formed on the first cantilever 205 and the second cantilever 206, the first cantilever 205 and the second cantilever 206 are driven to move outwards, so that the first cutting knife set 210 and the second cutting knife set 220 are driven to move towards the plate to finish cutting, and when an opposite pulse signal is input, the second servo motor 204 rotates reversely, so that the first cantilever 205 and the second cantilever 206 are retracted. Meanwhile, the cutting table 200 is built in, so that the second servo motor 204, the first cantilever 205 and the second cantilever 206 can be arranged to realize synchronous and accurate control of the first cutting knife group 210 and the second cutting knife group 220.
