[0002] CNC machining usually refers to precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines, etc. In the existing CNC machining, manual assistance is mostly used. The specific operation is to manually pick up and place products on the CNC clamping fixture. When processing products, it will cause processing iron chips and other debris to fall on the workbench surface. The general cleaning method is to use manual handheld cleaning tools to clean it. This method is not only inefficient and ineffective, but also has certain safety hazards when cleaning debris and impurities. Therefore, to address the above problems, an automatic clamping and cleaning device inside the CNC machine is proposed. Utility Model Content

[0003] The purpose of the utility model is to provide an automatic clamping and cleaning device in a CNC machine to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: an automatic clamping and cleaning device in a CNC machine, comprising a bracket and a CNC machine tool;

[0010] CNC machining usually refers to precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines, etc. In the existing CNC machining, manual assistance is mostly used. The specific operation is to manually pick up and place the product on the CNC clamping fixture. When processing the product, it will cause the processing iron chips and other debris to fall on the surface of the workbench. The general cleaning method is to use manual handheld cleaning tools to clean it. It is not only inefficient and ineffective, but also has certain safety hazards when cleaning debris and impurities. When in use, an external power supply is connected. After the CNC machine tool completes the processing action, the product is taken out, and then the second motor is started to drive the rotating shaft. The rotation causes the moving block to move, and the fixed frame, reciprocating table, rotating sleeve, unfolding frame and cleaning nozzle follow the movement. At this time, the debris collection mechanism is started, and the processing debris enters the debris collection mechanism through the cleaning nozzle for collection. This automatic cleaning method only requires the unfolding frame to move once from the workbench to complete the impurity cleaning purpose.

When the unfolding frame moves, it drives the rotating shaft to rotate through the first motor, thereby rotating the reciprocating screw rod.

[0011] Furthermore, the debris collection mechanism includes a collection cylinder, an air pump and an air suction hood. The top of the collection cylinder is connected to an air pipe, an air pump is installed inside the collection cylinder, the air inlet end of the air pump is connected to the air suction hood, and a mesh cover is provided at the other end of the air suction hood, and a sliding frame is fixedly connected to the outside of the mesh cover.

[0013] Furthermore, a plurality of groups of raised covers are installed inside the mesh cover in a raised manner.

[0014] The debris falls into the mesh cover through the air pipe, which can realize the centralized collection of the debris. The raised cover can prevent the debris from accumulating on the surface of the mesh cover and affecting the normal air circulation. The sliding frame can be conveniently pulled out of the mesh cover for processing.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. When the utility model is in use, after the CNC machine tool completes the processing action, the product is taken out, and then the second motor is started to drive the rotating shaft to rotate, thereby moving the moving block, and the fixed frame, reciprocating table, rotating sleeve, unfolding frame and cleaning nozzle follow the movement. At this time, the debris collection mechanism is started, and the processing debris enters the debris collection mechanism through the cleaning nozzle for collection. This automatic cleaning method only requires the unfolding frame to move once from the workbench to complete the impurity cleaning purpose, and its cleaning efficiency is higher, and no manual participation is required, thereby ensuring the safety of the staff;

[0017] 2. When the unfolding frame is moving, the first motor drives the rotating shaft to rotate, thereby rotating the reciprocating screw. Under the action of the slider and the reciprocating table, the unfolding frame can move back and forth in the horizontal direction, thereby ensuring the cleaning quality of the cleaning nozzle on the work surface;

[0018] 3. The debris falls into the mesh cover through the air pipe, which can realize the centralized collection of the debris.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figure 1 and Figure 2 , the utility model provides a technical solution:

[0025] A CNC machine automatic clamping and cleaning device, comprising a bracket 1 and a CNC machine tool 2;

[0026] A CNC machine tool 2 is installed on the top of the bracket 1;

[0027] A cleaning mechanism 3 for cleaning tabletop debris is installed on the side of the bracket 1, and the other end of the cleaning mechanism 3 is connected to a debris collecting mechanism 4;

[0028] The above-mentioned cleaning mechanism 3 includes a moving block 301 and a fixed frame 302. The top of the above-mentioned moving block 301 is fixedly connected to the fixed frame 302. The inside of the above-mentioned fixed frame 302 is slidably connected to a reciprocating table 307, and the top of the reciprocating table 307 is rotatably connected to a rotating sleeve 308. One side of the above-mentioned rotating sleeve 308 is fixedly connected to an expansion frame 309. Multiple groups of cleaning nozzles 310 are installed at the bottom of the above-mentioned expansion frame 309. The top of the above-mentioned cleaning nozzle 310 is connected to an air pipe 311, and the other end of the above-mentioned air pipe 311 is connected to the debris collection mechanism 4.

[0029] A second motor 313 fixedly connected to the bracket 1 is provided on the rear side of the above-mentioned moving block 301, and the end of the main shaft of the second motor 313 is fixedly connected to the rotating shaft 312, the other end of the above-mentioned rotating shaft 312 is rotatably connected to the bracket 1, the outer side of the above-mentioned rotating shaft 312 is spirally connected to the moving block 301, and one side of the moving block 301 is slidably connected to the bracket 1.

[0030] A first motor 303 is fixedly connected to one side of the fixed frame 302, a rotating shaft 304 is fixedly connected to the end of the main shaft of the first motor 303, and a reciprocating screw 305 is fixedly connected to the central end of the rotating shaft 304. A slider 306 is slidably connected to the outer side of the reciprocating screw 305, and the other end of the slider 306 is fixedly connected to the reciprocating table 307.

[0031] CNC machining usually refers to precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines, etc. In the existing CNC machining, manual assistance is mostly used. The specific operation is to manually pick up and place products on the CNC fixture. When processing products, it will cause processing iron chips and other debris to fall on the surface of the workbench. The general cleaning method is to use manual handheld cleaning tools to clean it. Not only is the cleaning efficiency low, the cleaning effect is poor, and there are certain safety hazards when cleaning debris and impurities. When using an external power supply, the CNC machine tool 2 completes the processing. After the work is completed, the product is taken out, and then the second motor 313 is started to drive the rotating shaft 312 to rotate, thereby moving the moving block 301, and the fixed frame 302, the reciprocating table 307, the rotating sleeve 308, the unfolding frame 309 and the cleaning nozzle 310 follow the movement. At this time, the debris collection mechanism 4 is started, and the processing debris enters the debris collection mechanism 4 through the cleaning nozzle 310 for collection. This automatic cleaning method only requires the unfolding frame 309 to move once from the workbench to complete the impurity cleaning purpose, which has higher cleaning efficiency and does not require manual intervention, ensuring the safety of the staff;

[0032] When the unfolding frame 309 moves, the first motor 303 drives the rotating shaft 304 to rotate, thereby rotating the reciprocating screw 305. Under the action of the slider 306 and the reciprocating table 307, the unfolding frame 309 can move back and forth in the horizontal direction, thereby ensuring the cleaning quality of the cleaning nozzle 310 on the work surface;

[0033] In this embodiment, when the unfolding frame 309 moves in the horizontal direction, its moving distance is the distance between the two cleaning nozzles 310, thereby ensuring that the cleaning nozzle 310 comprehensively cleans the workbench and ensures the quality of cleaning. At the same time, the bottom of the reciprocating table 307 contacts the bottom of the fixed frame 302, and the reciprocating table 307 can be guaranteed to move stably. The forward and reverse switching of the second motor 313 can drive the moving block 301 to move stably. Since one side of the moving block 301 contacts the side of the bracket 1, the moving block 301 can be guaranteed to move stably. When not in use, by rotating the unfolding frame 309 to one side, away from the workbench, the CNC machine tool 2 can be guaranteed to work normally.

[0034] Example 2: This example is an improvement on Example 1. Figure 3 Specifically, the debris collection mechanism 4 includes a collection cylinder 401, an air pump 402 and an air suction hood 403. The top of the collection cylinder 401 is connected to the air pipe 311, and the air pump 402 is installed inside the collection cylinder 401. The air inlet end of the air pump 402 is connected to the air suction hood 403, and the other end of the air suction hood 403 is provided with a mesh cover 405, and the outer side of the mesh cover 405 is fixedly connected to the sliding frame 404.

[0035] The sliding frame 404 is arranged on the outside of the collecting tube 401 in the shape of a semicircle.

[0036] A plurality of raised covers 406 are installed inside the mesh cover 405.

[0037] Debris falls through the air pipe 311 into the mesh cover 405, which can be collected centrally. The raised cover 406 can prevent debris from accumulating on the surface of the mesh cover 405 and affecting the normal air circulation. The sliding frame 404 is convenient for directly pulling out the mesh cover 405 for processing.

[0038] In this embodiment, when debris is processed, the air flow can be driven by starting the air pump 402, and the air in the air pipe 311 flows, so that the cleaning nozzle 310 can absorb dust and debris, and the debris falls to the surface of the mesh cover 405 to achieve the filtering purpose, and the raised cover 406 can prevent the debris from being on its surface, ensuring the smooth flow of air. After use, the mesh cover 405 can be removed by pulling the sliding frame 404, and the output end of the air pump 402 is connected to the outside of the collection tube 401 to ensure that the air is discharged smoothly.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
