[0004] Based on the above prior art, the existing eccentric sleeve processing equipment still has the following problems. When the existing eccentric sleeve processing equipment processes a cylindrical eccentric sleeve, it usually clamps the periphery of the eccentric sleeve. However, during the clamping process, the eccentric sleeve will shift in position due to vibration, which will cause errors in the processing accuracy of the eccentric sleeve. For this reason, the utility model provides an eccentric sleeve processing equipment. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an eccentric sleeve processing equipment, which solves the following problems existing in the existing eccentric sleeve processing equipment.

[0025] Please refer to Figures 1 - 5 , the present invention provides a technical solution:

[0026] An eccentric sleeve processing device, including a base 1, a processing mechanism 4 is arranged on the top of the base 1, a protection mechanism 3 is arranged on the top of the base 1 to block the splashing of processing waste, and a clamping unit 2 is arranged on the top of the base 1 to perform double-axis clamping on the eccentric sleeve. The clamping unit 2 includes:

[0027] A driving unit 21, arranged on the top of the base 1 and used to provide kinetic energy;

[0028] A linkage unit 22, arranged on the top of the driving unit 21 and used to clamp the eccentric sleeve;

[0029] A positioning unit 23, arranged above the linkage unit 22, including a fixing frame 231, a rotating shaft 232 is rotatably installed inside the fixing frame 231, a clamping rod 233 is fixedly installed on the outer circle of the rotating shaft 232, a pressing block 235 is fixedly installed at the top end of the clamping rod 233, and a pressing block 235 is fixedly installed on the inner side of the clamping rod 233.

[0030] When the four linkage blocks 223 drive the four fixing frames 231 to move towards the center, the pressing block 235 contacts the outer circle of the eccentric sleeve to clamp the side of the eccentric sleeve. The pressing block 235 drives the clamping rod 233 to rotate with the rotating shaft 232 as the axis, so that the bottom end of the clamping rod 233 retracts into the inside of the fixing frame 231. At the same time, the abutting block 234 presses down the edge of the top of the eccentric sleeve through the inclined plane, thereby realizing the double-axis clamping of the pressing and side of the eccentric sleeve, thus avoiding the situation that the eccentric sleeve will have a position offset due to vibration during processing, resulting in an error in processing accuracy.

[0031] In this embodiment, the driving unit 21 includes a base 211 fixedly installed on the top of the base 1, a linkage disk 212 is rotatably installed inside the base 211, a motor 213 is fixedly installed at the bottom of the inner cavity of the base 211, and an output end of the motor 213 is fixedly installed with a gear 214, and the gear 214 meshes with the teeth at the bottom of the linkage disk 212.

[0032] The motor 213 rotates, driving the gear 214 to rotate. The gear 214 drives the linkage disk 212 to rotate. At this time, the linkage disk 212 meshes with the teeth at the bottom of the linkage block 223 through the scroll teeth at the top, driving the four linkage blocks 223 to move towards the center.

[0033] In this embodiment, the linkage unit 22 includes a limit seat 221 fixedly installed on the top of the base 211. Four cross chutes 222 are opened inside the limit seat 221. A linkage block 223 is slidably installed inside the cross chutes 222. The teeth at the bottom of the linkage block 223 mesh with the scroll teeth at the top of the linkage disk 212. And the fixed frame 231 is fixedly installed on the top of the linkage block 223.

[0034] In this embodiment, a collection groove 224 is opened inside the limit seat 221, and a support ring 225 is fixedly installed inside the collection groove 224.

[0035] The eccentric sleeve is placed above the support ring 225. There is a certain space between the eccentric sleeve and the bottom of the collection groove 224 to prevent the drill bit 45 from drilling into the limit seat 221 and also to collect the waste materials.

[0036] In this embodiment, the protection mechanism 3 includes a track seat 31 fixedly installed on the top of the base 1. A track groove 32 is opened inside the track seat 31. A semi-circular hollow plate 33 is fixedly installed on the top of the track seat 31. A sliding plate 34 is slidably installed inside the semi-circular hollow plate 33. And the bottom end of the sliding plate 34 is slidably fitted inside the track groove 32. A pull block 35 is fixedly installed on the outer circle of the sliding plate 34.

[0037] When processing the eccentric sleeve, the user pulls the sliding plate 34 through the pull block 35, making the sliding plate 34 slide inside the semi-circular hollow plate 33 and the track groove 32, so that the sliding plate 34 and the semi-circular hollow plate 33 form a circle, thereby blocking the splashing of waste materials during processing and reducing the risk of harm to the operator.

[0038] In this embodiment, the processing mechanism 4 includes a fixed rod 41 fixedly installed on the top of the base 1. An installation frame 42 is fixedly installed on the top of the fixed rod 41. A cylinder 43 is fixedly installed on the top of the installation frame 42. The output end of the cylinder 43 penetrates through the installation frame 42 and is fixedly installed with a drilling machine 44. The output end of the drilling machine 44 is fixedly installed with a drill bit 45.

[0039] At the same time, the content not described in detail in this specification belongs to the well-known prior art in the art.

[0040] During operation, first place the eccentric sleeve above the support ring 225. Then, the motor 213 rotates, driving the gear 214 to rotate. The gear 214 drives the linkage disk 212 to rotate. At this time, the linkage disk 212 meshes with the teeth at the bottom of the linkage block 223 through the scroll teeth at the top, driving the four linkage blocks 223 to move towards the center. When the linkage block 223 drives the fixed frame 231 to move towards the center, the pressing block 235 contacts the outer ring of the eccentric sleeve, clamping the side of the eccentric sleeve. The pressing block 235 drives the clamping rod 233 to rotate around the axis of the rotating shaft 232, causing the bottom end of the clamping rod 233 to retract into the interior of the fixed frame 231. At the same time, the abutting block 234 presses down the edge of the top of the eccentric sleeve through the inclined surface, pressing down and clamping the eccentric sleeve in a double axial direction on the side. Then, the user pulls the sliding plate 34 through the pulling block 35, causing the sliding plate 34 to slide inside the semi-circular hollow plate 33 and the track groove 32, forming a circle with the semi-circular hollow plate 33. Then, the drill 44 operates to drive the drill bit 45 to rotate. At the same time, the cylinder 43 operates to push the drill 44 and the drill bit 45 to process the eccentric sleeve.
