Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

In order to solve the problems, namely, the problem of poor surrounding sanitation caused by using an air gun to clean residual cutting fluid is solved. The application provides a cleaning device for residual cutting fluid, a numerically-controlled machine tool comprising the cleaning device and a cleaning method based on the numerically-controlled machine tool. Specific embodiments are described in detail below by way of examples.

Examples

Referring to fig. 1 and 2, fig. 1 is a front view of a numerically controlled machine tool provided with a cleaning device for residual cutting fluid according to an embodiment of the present application, and fig. 2 is an oblique view of the numerically controlled machine tool provided with the cleaning device for residual cutting fluid according to an embodiment of the present application. The cleaning device for the residual cutting fluid is used for cleaning the cutting fluid residual in the groove of the part machined by the numerical control machine tool. As shown in fig. 1 and 2, the cleaning device mainly comprises a power device 1 arranged on a numerical control machine 4 (fig. 1 and 2 only show a part of the numerical control machine), and a liquid inlet pipe 2 and a liquid outlet pipe 3; wherein, one end of the liquid inlet pipe 2 is provided with a liquid inlet 7, and the other end is connected with the inlet of the power device 1; one end of the liquid outlet pipe 3 is connected with the outlet of the power device 1; and the liquid inlet 7 can move so as to suck the cutting liquid remained at different positions of the part 6 into the power device 1 when the power device 1 operates, and then the cutting liquid is discharged to the storage device through the liquid outlet pipe 3.

Based on the device, after the numerically-controlled machine tool finishes processing the part 6, the liquid inlet 7 can be moved to a specific position (namely, a groove position) of the part, the power device 1 is started, and the power device 1 sucks and discharges the cutting liquid remained in the part 6. The power device 1 may include a common power source such as an air pump, and its power source end may be connected to the power module of the numerical control machine, and is powered by the numerical control machine, or may be externally connected to a power supply.

Therefore, when the residual cutting fluid in the groove of the part machined by the numerical control machine tool is cleaned, the residual cutting fluid in the groove of the part is sucked away and discharged into the storage device through the cleaning device for the residual cutting fluid comprising the power device 1, the liquid inlet pipe 2 and the liquid outlet pipe 3, and compared with the traditional mode of manually blowing the residual cutting fluid by using an air gun, the sanitation environment around the numerical control machine tool can be effectively improved. Wherein, it is portable to set up liquid inlet 7 of feed liquor pipe 2 into the position to can clear up the remaining cutting fluid in the different positions of part conveniently.

On the basis of the above scheme, in some embodiments, the power device 1 comprises a filtering component, and the filtering component is used for filtering the cutting fluid sucked into the power device 1. The filtering process is mainly used for filtering chips generated in the part machining process, and the filtered cutting fluid can be reused. Based on this, the storage device used in the present embodiment may be the cutting fluid storage device 8 that is originally provided for the numerical control machine tool. That is, the cutting fluid sucked and filtered by the power device 1 can be discharged to the original cutting fluid storage device 8 (the position of which is shown in fig. 1 and 2) of the numerical control machine tool, so that the recycling of the recovered cutting fluid can be realized, and the material cost is reduced. Moreover, it should be noted that, in the actual cleaning process, an outer protective door (not shown in the figure) of the numerical control machine tool is in a closed state, so that the outlet of the liquid outlet pipe 3 and the cutting fluid storage device 8 have a certain height difference without extending into the cutting fluid storage device 8 (that is, without considering the possible cutting fluid splashing problem), so that the length of the liquid outlet pipe 3 can be shortened, and the position where the liquid outlet pipe is arranged can be conveniently adjusted.

In addition, in some embodiments, the power device 1, the liquid inlet pipe 2 and the liquid outlet pipe 3 are detachably arranged on the numerical control machine tool. Therefore, the maintenance of each part of the cleaning device is convenient; and when the machined part does not have structures such as grooves and the like and does not need to clean residual cutting fluid, the cleaning device can be integrally detached, so that the influence possibly existing in the operation of the numerical control machine tool is reduced.

Further, for a specific implementation of the detachable connection, the following two possible solutions are provided:

the first scheme is as follows: the power device 1 is arranged on the numerical control machine tool through a switch type magnetic base (magnetic base), and the liquid inlet pipe 2 and the liquid outlet pipe 3 are arranged on the numerical control machine tool through a magnetic pipe clamp. The magnetic size of the magnetic base can be changed by adjusting the angle of the magnetic element of the switch type magnetic base (namely, adjusting the switch), so that the magnetic base is fixed on the magnetic material structure of the numerical control machine tool, or the magnetic base is detached from the numerical control machine tool, and the structure of the numerical control machine tool cannot be damaged. The magnetic pipe clamp is similar, and the U shape or other shapes can be selected according to actual needs to fix the pipeline at a set position.

Scheme II: the power device 1, the liquid inlet pipe 2 and the liquid outlet pipe 3 are all arranged on the numerical control machine tool through glue hanging buckles. Convenient fixing can also be realized through gluing the knot of hanging, and can not cause the damage to the structure of digit control machine tool.

Of course, other similar connections may be used, but preference is given to ways that do not damage the structure of the machine tool.

Regarding the arrangement position of each component, for example, as shown in fig. 1, the power unit 1, the liquid inlet pipe 2 and the liquid outlet pipe 3 may be arranged on the side surface of the main shaft 5 of the numerical control machine tool, and the liquid inlet 7 may be arranged near the head of the main shaft 5. In particular, it is preferable for the liquid inlet 7 to be arranged on the spindle 5 of the numerical control machine so that it can follow the spindle 5 of the numerical control machine, thus making the most use of the flexibility of the spindle 5 itself. Of course, the specific setting position of each component can be adjusted according to the actual situation, and the principle is as follows: the first working process that need not influence digit control machine tool itself, the second is portably changed, guarantees that installation and dismantlement are all simple easy operation.

In addition, in some embodiments, the portion of the liquid inlet pipe 2 near the end of the liquid inlet 7 is of a telescopic structure. Therefore, the axial, transverse and angular thermal deformation of the pipeline can be compensated, and vibration can be absorbed, so that the liquid inlet pipe 2 and the liquid inlet 7 are effectively protected, and the service life is prolonged. Of course, it can be understood that, in practical application, the liquid inlet pipe 2 and/or the liquid outlet pipe 3 may be integrally provided with telescopic pipes according to actual needs, so as to protect each pipeline.

In addition, when the liquid inlet is arranged on a main shaft of a numerical control machine tool, in order to further simplify the operation of an operator, the cleaning program can be written by utilizing numerical control machine tool programming software such as UG (user generated content) or Powermill and the like according to a 3D (three-dimensional) data model of a part to be cleaned, the writing principle is similar to that of writing the part processing program, the cleaning program can be stored in the numerical control machine tool after being written, after the part processing is completed, the operator can directly run the cleaning program, the start key power device is started to start to operate, and during the period, the numerical control machine tool can be accurately controlled to drive the liquid inlet to run to the designated position of the part through cleaning program codes, the cutting liquid is sucked from the liquid inlet and then filtered by the internal filtering part and then discharged from the liquid outlet of the liquid outlet pipe, and enters a cutting liquid storage device of the machine tool, namely enters a cutting liquid circulating system of the machine tool. When the part comprises a plurality of grooves, the residual cutting fluid at each part of the part can be cleaned and recovered in sequence, and the cutting fluid is recycled. In addition, in practical application, the printed drawing can be attached to the back of the part program list after the cleaning program is compiled, so that operators can conveniently look up the drawing.

Based on this, as shown in fig. 3, an embodiment of the present application further provides a method for cleaning residual cutting fluid, which is performed by a numerical control machine tool including the above-mentioned device for cleaning residual cutting fluid, and specifically includes:

s101: after the cleaning instruction is obtained, calling and executing a pre-written cleaning program; the cleaning instruction can be generated by an operator through triggering of a physical key or a virtual key;

s102: based on the cleaning program, a main shaft of the numerical control machine tool is controlled to drive the liquid inlet to move according to a set running track, and the power device is controlled to run so as to clean the residual cutting liquid of the part to be cleaned.

Through above-mentioned scheme, after parts machining accomplished, when the cutting fluid of the surplus deposit of needs clearance, operating personnel can quick start the cleaning procedure of digit control machine tool to clear up the recovery by digit control machine tool is automatic to the cutting fluid, reduce operating personnel's time and operating cost. And if the filter component is arranged in the cleaning device, the cutting fluid can be recycled, so that the material cost is reduced.
