Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, and in particular to a chip removal device for CNC lathes. Background Technology

[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting and machining the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and reaming.

[0003] During the turning process, CNC lathes generate chips, which need to be collected by a collection device. In the current technology, most CNC lathes produce a lot of chips of different sizes during use. These chips and dust adhere to and accumulate on the filter plate, causing the filter plate to become clogged. After clogging, the dust and chips mix together, which is not conducive to the recycling of chips. It requires frequent manual cleaning, which is time-consuming, labor-intensive, and impractical. Therefore, it is necessary to design an anti-clogging chip removal device for CNC lathes to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-clogging and chip removal device for CNC lathes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as a cam, a spring telescopic rod, and a filter screen, when the cam rotates continuously and intermittently contacts the inner wall of the extrusion groove, the spring telescopic rod can elastically drive the filter screen to shake up and down. When the filter screen shakes, larger debris can be filtered through its gaps into the first collection box, while smaller debris can slide down its upper surface into the second collection box. This allows for the filtration and collection of debris of different sizes, preventing debris from accumulating on the upper surface of the filter screen and causing blockage.

[0014] 2. By setting up components such as lead screw sleeve, gears and toothed plates, the lead screw sleeve can drive the cleaning roller to move in contact with the workbench surface when it moves. During this process, the rotating shaft of the cleaning roller can drive the gear and toothed plate to mesh at the same time. Through the gear meshing with the toothed plate, the rotating shaft of the cleaning roller can rotate on the outer wall of the lead screw sleeve. Thus, the cleaning roller can rotate during the movement. When the cleaning roller moves back and forth, it can clean the debris on the surface of the workbench. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A chip removal and anti-clogging device for a CNC lathe includes a worktable 1. A reciprocating screw 3 is rotatably mounted on the upper surface of the worktable 1 via a movable frame 2. A first motor 4 connected to the reciprocating screw 3 is fixedly mounted on the outer wall of the movable frame 2. A screw sleeve 6 is threadedly mounted on the outer wall of the reciprocating screw 3 via a limiting mechanism. The limiting mechanism includes a limiting rod 5 fixedly mounted on the inner wall of the movable frame 2. The limiting rod 5 slides through the screw sleeve 6 and can limit the screw sleeve 6, so that the screw sleeve 6 can only move axially along the outer wall of the reciprocating screw 3. A cleaning roller 7 is rotatably mounted on the outer wall of the screw sleeve 6. A toothed plate 9 is fixedly mounted on the upper surface of the worktable 1. The outer wall of the rotating shaft of the cleaning roller 7 is connected to the toothed plate 9 via a meshing mechanism. The meshing mechanism includes a gear 8 fixedly mounted on the outer wall of the rotating shaft of the cleaning roller 7. The gear 8 and the toothed plate 9 mesh with each other. A collection groove is opened on the outer wall of the worktable 1, and a collection opening that cooperates with the collection groove is opened on the upper surface of the worktable 1.

[0023] A fixing plate 10 is fixedly installed on the inner wall of the collection tank. A filter screen plate 12 is fixedly installed on the upper surface of the fixing plate 10 through an elastic mechanism. The elastic mechanism includes a spring telescopic rod 11 fixedly installed on the upper surface of the fixing plate 10. The telescopic end of the spring telescopic rod 11 is fixedly connected to the bottom wall of the filter screen plate 12. An extrusion block 13 is fixedly installed on the bottom wall of the filter screen plate 12. An extrusion groove is opened on the bottom wall of the extrusion block 13. A connecting plate 14 is fixedly installed on the bottom wall of the filter screen plate 12. An extrusion shaft 15 is rotatably installed between the connecting plate 14 and the inner wall of the collection tank. A second motor 16 connected to the extrusion shaft 15 is fixedly installed on the outer wall of the worktable 1. A cam 17 is fixedly installed on the outer wall of the extrusion shaft 15. A first collection box 18 and a second collection box 19 that cooperate with the filter screen plate 12 are slidably installed inside the collection tank.

[0024] A support plate 20 is fixedly installed on the upper surface of the workbench 1. A fan 22 is fixedly installed on the outer wall of the support plate 20 through an installation mechanism. The installation mechanism includes an installation plate 21 fixedly installed on the outer wall of the support plate 20. The fan 22 is fixedly installed on the upper surface of the installation plate 21. A dust suction hood 23 is fixedly installed on the outer wall of the inlet pipe of the fan 22. A dust collection bag 24 is fixedly installed on the outer wall of the outlet pipe of the fan 22. The dust collection bag 24 is a key component in the bag filter, used to filter solid particles in the dust-laden gas. The dust collection bag 24 captures solid particles in the dust-laden gas through its fiber structure, realizing gas-solid separation. The outlet pipe of the fan 22 extends into the interior of the dust collection bag 24.

[0025] When this utility model is used, a lot of debris is generated during the turning process. The first motor 4 drives the reciprocating screw 3 to rotate. When the reciprocating screw 3 rotates, it can drive the screw sleeve 6 to move through the cooperation with the limit rod 5. When the screw sleeve 6 moves, it can drive the cleaning roller 7 to move in contact with the surface of the worktable 1. During this process, the rotating shaft of the cleaning roller 7 can drive the gear 8 to mesh with the toothed plate 9 while moving. Through the meshing of the gear 8 with the toothed plate 9, the rotating shaft of the cleaning roller 7 can rotate on the outer wall of the screw sleeve 6. Thus, the cleaning roller 7 can rotate during the movement. When the cleaning roller 7 reciprocates and rotates, it can clean the debris on the surface of the worktable 1. At this time, the debris falls into the collection tank through the collection opening and is located on the upper surface of the filter screen plate 12 inside the collection tank.

[0026] Meanwhile, the second motor 16 drives the extrusion shaft 15 to rotate. The rotation of the extrusion shaft 15 drives the cam 17 to rotate and contact the inner wall of the extrusion groove. At this time, the extrusion block 13 is subjected to force, which can drive the filter screen plate 12 to move upward and pull the spring telescopic rod 11. When the cam 17 is not in contact with the inner wall of the extrusion groove, the elasticity of the spring telescopic rod 11 can drive the filter screen plate 12 to move and return to its original position. When the cam 17 rotates continuously and intermittently contacts the inner wall of the extrusion groove, the elasticity of the spring telescopic rod 11 can drive the filter screen plate 12 to shake up and down. When the filter screen plate 12 shakes, it can filter larger debris through its gaps into the first collection box 18. Inside, smaller debris can slide down its upper surface into the second collection box 19, thereby filtering and collecting debris of different sizes and preventing debris from accumulating on the upper surface of the filter plate 12 and causing blockage. During the cleaning of debris, the dust generated in the process can be sucked up by the inlet pipe of the fan 22 in cooperation with the dust suction hood 23, and the sucked dust is discharged into the dust collection bag 24 through the outlet pipe of the fan 22. The dust collection bag 24 can intercept and filter the dust in the air, and the filtered air can be discharged from its interior, thereby preventing the dust generated during operation from affecting the operator's health.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
