Description

Technical Field

[0001] The utility model relates to the technical field of eccentric shafts, in particular to an eccentric shaft processing tool. Background Art

[0002] The eccentric shaft consists of a main shaft part and an eccentric cylindrical part. When the eccentric cylindrical part is ground, tooling is required to fix the eccentric shaft.

[0003] When current positioning tools are used to process eccentric shafts of different specifications, they mostly clamp the main shaft part. When it is necessary to coincide the axis of the eccentric cylinder with the rotation axis of the tool, the operation is quite difficult. If the axes of the two cannot coincide effectively, it is difficult to maintain consistency in the contact force with the polishing workpiece when the tool drives the eccentric shaft to rotate and polish.

[0004] Therefore, an eccentric shaft processing tool is needed, which can quickly make the axis of the eccentric cylinder in the eccentric shaft coincide with the rotation axis of the tool. Utility Model Content

[0005] The utility model aims at least to solve the problem in the prior art that it is difficult to coincide the axis of the eccentric cylinder in the eccentric shaft with the rotation axis of the tooling.

[0006] The present invention provides an eccentric shaft processing tool, which is achieved by the following specific technical means: it includes a base and a processing truncated table rotatably arranged on the base, a track groove 1 is radially fixed on the top surface of the processing truncated table, the track groove 1 passes through the center of the processing truncated table, and track grooves 2 are symmetrically arranged on both sides of the track groove 1, and the connecting line between the two groups of the track grooves 2 also passes through the center of the processing truncated table, and the track groove 2 is perpendicular to the track groove 1, and clamping members are slidably arranged in the two groups of the track grooves 2, and the two groups of the clamping members can clamp the eccentric cylinder when they are close to each other, and at this time, the axis of the eccentric cylinder coincides with the axis of the processing truncated table, and a fixing seat is slidably arranged in the track groove 1, and the fixing seat is used to clamp and fix the main shaft.

[0007] Preferred technical solution 1: The clamping member includes a slider slidably arranged in the track groove 2 and a telescopic rod 1 fixed on the slider, and a V-shaped clamp is fixed to the top telescopic end of the telescopic rod 1.

[0008] Preferred technical solution 2: A screw rod is rotatably provided in the second track groove, and the slider is slidably sleeved on the screw rod.

[0009] Preferred technical solution three: an electric clamp for clamping the fixed main body shaft is arranged on the top of the fixed seat, and a telescopic rod 2 is also arranged in the inner cavity of the fixed seat. The telescopic end of the telescopic rod 2 extends from the side wall of the fixed seat and presses on a wall of the track groove when the telescopic rod 2 is extended.

[0010] The above structure enables this solution to have the following beneficial effects:

[0011] 1. Compared with the traditional positioning tooling, this solution can quickly realize the coaxial positioning and fixing of the eccentric cylinder in the eccentric shaft through structural setting, which is convenient for subsequent processing;

[0012] 2. The structural setting of the clamping piece enables it to be suitable for positioning and fixing eccentric cylinders with different diameters and heights. BRIEF DESCRIPTION OF THE DRAWINGS
