Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to a tool used for gear processing. Background Art

[0002] Gears are mechanical components with teeth on their rims that can continuously mesh to transmit motion and power. They are toothed mechanical parts that can mesh with each other. The tooling used for gear processing mainly includes two categories: fixtures and tools. During the gear processing process, fixtures are needed to clamp and fix the raw materials to prevent the gear position from shifting during processing, which would affect the accuracy of the gear processing.

[0003] For example, the patent with announcement number CN216966526U discloses a positioning fixture for gear processing, which includes a mounting ring, two mirror-image arc-shaped fixed clamps arranged inside the mounting ring, two mirror-image arc-shaped support plates fixedly connected to the opposite surfaces of the two arc-shaped fixed clamps, the upper surface of the arc-shaped support plates rotatably connected to a rotating shaft, the upper surface of the arc-shaped fixed clamps fixedly connected to a control block, a control cavity is provided in the control block, the upper end of the rotating shaft rotates and penetrates into the control cavity, and a control gear is fixedly connected to one end of the rotating shaft located in the control cavity. The control gear is fixed by the clamping plate, thereby preventing the rotating shaft from rotating. Therefore, when the rotating shaft and the roller rotate during the gear processing, causing the gear to deviate, the stability of the gear processing is further guaranteed, and the effect of the gear processing is improved.

[0004] However, the processing tooling in the above technology still has the following problems:

[0005] Although the control gear is fixed by the clamping plate, which improves the stability of the gear during processing, the two arc-shaped fixed clamps only use the spring to provide clamping force when clamping the gear in the middle position, and the clamping force of the gear cannot be guaranteed. This may cause the gear to drive the two arc-shaped clamps to swing left and right in the mounting ring during processing, resulting in poor stability. At the same time, the mounting ring cover is installed on the outside of the two arc-shaped fixed clamps, which will form an obstruction on the side when polishing the gear tooth groove or processing the gear side, thereby hindering the side processing of the gear. Utility Model Content

[0006] In view of the deficiencies of the prior art, the present invention provides a tool for gear processing, such as: after the gear to be processed is clamped and fixed, the side surface of the gear can be exposed, thereby facilitating the grinding and polishing of the tooth groove of the gear.

Adjustment screw holes are provided at the bottom of the two adjustment columns, one end of the bidirectional screw is rotatably connected to one of the support blocks, and the other end passes through the two adjustment screw holes in sequence and passes through the other support block.

[0011] Furthermore, a lifting groove is provided on the side of the adjusting column close to the arc-shaped splint, a lifting block is slidably connected in the lifting groove, and the side of the lifting block away from the lifting groove is fixedly connected to the arc-shaped splint. A lifting screw is rotatably connected to one end of the lifting groove close to the processing table, and the other end of the lifting screw passes through the lifting block and the other end of the lifting groove in sequence, and is fixedly connected to a rotating handle.

[0012] Furthermore, a suspended column is fixedly connected to the upper surface of the processing table, the suspended column is located between the two adjustment grooves, and a downward pressing component is provided above the suspended column.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] See also Figure 1 - Figure 5A tool for gear processing includes a processing table 1, the four corners of the bottom of the processing table 1 are fixedly connected to support legs 2, and two symmetrically arranged adjustment slots 101 are provided through the middle position of the upper surface of the processing table 1. Adjustment columns 3 are slidably connected in the two adjustment slots 101, and the bottoms of the two adjustment columns 3 are simultaneously connected to adjustment components, and arc-shaped splints 4 are connected to the adjacent sides of the two adjustment columns 3 and located above the processing table 1.

[0026] like Figure 1 - Figure 5 As shown, the tooling for gear processing in the present invention is similar to the existing tooling structure for gear processing, such as a positioning fixture for gear processing disclosed in patent publication number CN216966526U. The main improvement of the present invention is that after the gear is clamped and fixed, the tooth grooves on the side of the gear can be polished and polished. Figures 1 to 5 As shown, when the tooling for gear processing in the present invention is in use, the two adjusting columns 3 are driven by the adjusting component to move relative to each other in the two adjusting grooves 101, thereby driving the two arc-shaped clamping plates 4 located above the processing table 1 to move relative to each other, so that the gear to be processed can be clamped above the processing table 1, exposing both sides of the gear to be processed, which is convenient for grinding and polishing the tooth grooves or teeth on both sides of the gear.

[0027] like Figure 1 - Figure 4 As shown, the adjustment assembly includes a bidirectional screw rod 5 and two support blocks 6. Both support blocks 6 are fixedly connected to the bottom of the processing table 1, and the two support blocks 6 are respectively located below the two adjustment slots 101 at one end away from each other. The bottoms of the two adjustment columns 3 are each provided with an adjustment screw hole 301. One end of the bidirectional screw rod 5 is rotatably connected to one of the support blocks 6, and the other end passes through the two adjustment screw holes 301 in sequence and penetrates the other support block 6. By rotating the bidirectional screw rod 5 between the two support blocks 6 and through the adjustment screw holes 301 at the bottoms of the two adjustment columns 3, the two adjustment columns 3 are synchronously driven to slide in the adjustment slots 101, and it is ensured that the movement direction of the two adjustment columns 3 always remains close to or away from each other, thereby clamping and fixing gears of different diameters.

[0028] like Figure 1 - Figure 3 As shown, one end of the bidirectional screw rod 5 passing through the support block 6 is connected to a drive motor 7, which is fixedly connected to the processing table 1 through a mounting base, and the output shaft of the drive motor 7 is fixedly connected to the end of the bidirectional screw rod 5. By starting the drive motor 7, the bidirectional screw rod 5 is driven to rotate, which makes it more convenient to clamp and fix the gear, and by locking the position of the drive motor 7, the clamped gear can be fixed.

[0029] like Figure 1 - Figure 3As shown, a support slide bar 8 is fixedly connected to the inner wall of one end of the adjustment groove 101. The other end of the support slide bar 8 passes through the adjustment column 3 and is fixedly connected to the other end of the adjustment groove 101. The support slide bar 8 is slidably connected to the adjustment column 3. When the adjustment column 3 slides in the adjustment groove 101, the support slide bar 8 passes through the adjustment column 3, which can further strengthen the support for the adjustment column 3 and improve the stability of the adjustment column 3 sliding in the adjustment groove 101.

[0030] like Figure 3 and Figure 4 As shown, a lifting slot 302 is provided on the side of the adjustment column 3 near the arc-shaped clamping plate 4. A lifting block 9 is slidably connected to the lifting slot 302. The side of the lifting block 9 away from the lifting slot 302 is fixedly connected to the arc-shaped clamping plate 4. A lifting screw 10 is rotatably connected to the end of the lifting slot 302 near the processing table 1. The other end of the lifting screw 10 passes through the lifting block 9 and the other end of the lifting slot 302 in sequence and is fixedly connected to a rotating handle 11. By rotating the rotating handle 11, the lifting screw 10 is driven to rotate, and then the lifting block 9 threadedly connected to it is driven to slide up and down in the lifting slot 302, thereby adjusting the height of the arc-shaped clamping plate 4 on the adjustment column 3, facilitating better clamping and fixing of gear parts of different thicknesses.

[0031] like Figure 1 - Figure 3 As shown, a suspended column 12 is fixedly connected to the upper surface of the processing table 1. The suspended column 12 is located between the two adjustment slots 101. A pressing assembly is provided above the suspended column 12. When placing a gear, the gear is placed on the suspended column 12, thereby suspending the gear on the processing table 1. The suspended column 12 can provide bottom support for the gear, improving the stability during the grinding process of the gear side. After clamping and fixing, the pressing assembly can also be used to press the gear on the suspended column 12 to improve the fixing effect of the gear.

[0032] like Figure 1 - Figure 5 As shown, the pressing assembly includes a threaded pressing rod 13, a connecting rod 14 and a support column 15. One end of the support column 15 is fixedly connected to the upper surface of the processing table 1, and the support column 15 is located on the side edge of the processing table 1 away from the suspended column 12. The end of the support column 15 away from the processing table 1 is connected to the connecting rod 14. The end of the connecting rod 14 away from the support column 15 is penetrated by a pressing screw hole 102. The threaded pressing rod 13 is threadedly connected to the pressing screw hole 102. The threaded pressing rod 13 is located directly above the suspended column 12. By rotating the threaded pressing rod 13, the threaded pressing rod 13 moves downward in the pressing screw hole 102 of the connecting rod 14, so that the gear is pressed down on the suspended column 12.

[0033] like Figure 1 - Figure 5As shown, the end of the support column 15 away from the processing table 1 is connected to a T-shaped rotating rod 16. The thinner end of the T-shaped rotating rod 16 passes through the connecting rod 14 and is fixedly connected to the support column 15. The connecting rod 14 is rotatably connected to the T-shaped rotating rod 16. The T-shaped rotating rod 16 passes through the connecting rod 14 and is fixed to the support column 15, so that the connecting rod 14 can be rotated horizontally on the top of the support column 15 through the T-shaped rotating rod 16. When there is no need to press down and fix the gear, the space above the gear is exposed, making it easier to process the top of the gear.

[0034] like Figure 1 - Figure 5 As shown, one end of the threaded pressing rod 13 close to the suspended column 12 is fixedly connected to a rubber pressing sheet 17. When the threaded pressing rod 13 presses the gear onto the suspended column 12, the rubber pressing sheet 17 contacts the gear, which can reduce the extrusion damage to the gear.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated 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.
