DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0025] Embodiment 1

[0026] As Figures 1 to 3 shown, this embodiment proposes a lathe for sprocket production, including a lathe body 1. A processing chamber 6 is provided inside the lathe body 1. A grinding wheel 4 is slidably connected to the top of the processing chamber 6. A grinding rod 5 is rotatably connected to the inner wall of the processing chamber 6. An adjusting component 2 is fixed to the side of the inner wall of the processing chamber 6. A collecting component 3 is fixed to the bottom of the processing chamber 6;

[0027] The adjusting component 2 includes a positioning column 21. An adjusting column 25 is clamped on the side of the positioning column 21. A sliding groove 26 is provided inside the adjusting column 25. A connecting block 29 is fixed inside the sliding groove 26. A tooth groove 215 is provided in the connecting block 29. A positioning groove 27 is provided inside the sliding groove 26. An electric motor 28 is fixed in the positioning groove 27. A gear 210 is fixed to the output end of the electric motor 28. Rack bars 211 are meshed and connected to both sides of the gear 210. A clamping block 212 is fixed to one end of each rack bar 211. A processed sprocket 214 is clamped on the outside of the clamping block 212;

[0028] An installation groove 22 is provided on the side of the positioning column 21. An installation block 23 is fixed to the side of the adjusting column 25 close to the positioning column 21. The installation block 23 is clamped in the installation groove 22. An installation nut 24 is fixed to the outside of the positioning column 21. Through the settings of the installation nut 24 and the installation groove 22, when the structure at the top of the side of 25 is highly worn, the entire 25 can be replaced, so that the sprocket is fixed more firmly during processing;

[0029] A buffer soft pad 213 is fixed to the side of the clamping block 212. The buffer pad 213 can reduce the friction between the inner diameter of the processed sprocket 214 and the clamping block 212 when the clamping block 212 fixes the processed sprocket 214, so that the values of the processed sprocket are more accurate;

[0030] A stop block is fixed to the end of the rack bar 211 away from the clamping block 212. The stop block can prevent the rack bar 211 from disengaging from the gear 210 when moving excessively, resulting in a malfunction of the clamping block 212;

[0031] The shape of the sliding groove 26 is cross-shaped. The connection block 29 is fixed in the middle of the sliding groove 26. Two sets of tooth grooves 215 are provided inside the connection block 29. Both sets of tooth grooves 215 communicate with the sliding groove 26. The connection block 29 in the middle of the cross-shaped sliding groove 26 enables the opposite clamping blocks 212 in the sliding groove 26 to move towards each other or in opposite directions simultaneously, thereby adjusting the size.

[0032] In this embodiment, when the size of the sprocket is large, the processed sprocket 214 is clamped in the clamping block 212. The output end of the electric motor 28 drives the gear 210 to rotate clockwise in the tooth groove 215, causing the clamping block 212 on the side of the rack 211 meshed with the side of the gear 210 to move outward in the sliding groove 26, so that the buffer soft pad 213 on the side of the clamping block 212 clamps the inner diameter of the processed sprocket 214, fixing the processed sprocket 214. The fixed processed sprocket 214 is processed by the grinding rod 5 and the grinding wheel 4, and the generated debris is cleaned by the collection component 3 at the bottom of the processing chamber 6. The buffer soft pad 213 can reduce the frictional force generated when the clamping block 212 contacts the processed sprocket 214, preventing the inner diameter of the processed sprocket 214 from being worn due to the long-term close contact between the clamping block 212 and the processed sprocket 214, and avoiding unqualified quality of the produced processed sprocket 214. When the clamping block 212 on the side of the adjusting column 25 is damaged after long-term use, by unscrewing the mounting nut 24, the adjusting column 25 is detached from the mounting groove 22 in the positioning column 21 through the mounting block 23, and the adjusting column 25 is replaced. The mounting groove 22 and the mounting block 23 are clamped and fixed by the mounting nut 24, which is more convenient during disassembly and replacement.

[0033] Embodiment 2

[0034] As Figures 4 to 5 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that the collection component 3 includes a motor 31. The output end of the motor 31 is fixed with a fan 32. An air supply groove 33 is provided inside the lathe body 1. An air outlet 34 is provided on the side of the air supply groove 33 away from the fan 32. A conveying groove 36 is provided on the side of the processing chamber 6 away from the air outlet 34. A collection box 37 is fixed at the bottom of the conveying groove 36. A push-pull handle 38 is fixed on the side of the collection box 37;

[0035] The number of the air outlets 34 is nine groups. Isolation nets 35 are installed in all nine groups of air outlets 34. The isolation nets 35 can prevent debris from falling into the air supply groove 33 through the air outlets 34, preventing the accumulation of debris in the air supply groove 33 and causing blockage;

[0036] The surface of the isolation net 35 is provided with an anti-static coating. The isolation net 35 is a detachable device. The anti-static coating can prevent debris from adhering to the surface of the isolation net 35 and prevent blockage caused by debris. The detachable isolation net 35 can cause the anti-static coating on the surface of the isolation net 35 to fade after long-term use, resulting in debris adhering to the surface.

[0037] In this embodiment, when the sprocket is processed by the grinding wheel 4 and the grinding rod 5, debris will be generated. A large amount of debris accumulating at the bottom of the processing bin 6 is not only very wasteful but also easily affects the sprocket processing. The fan 32 is driven by the output end of the motor 31 to blow air into the air supply groove 33, so that the air will blow the debris into the conveying groove 36 at the other end of the processing bin 6 from the air outlet 34 on the side of the air supply groove 33. Through the conveying groove 36, the debris falls into the collection box 37 for collection. The collected debris can be used to produce sprockets again. The isolation net 35 fixed in the air outlet 34 can prevent debris from entering the air supply groove 33. The anti-static coating on the surface of the isolation net 35 can avoid the problem that debris adheres to the isolation net 35 and blocks the air outlet 34.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
