Description

Technical Field

[0001] The utility model relates to a hydraulic tool for processing a sanding machine shell, and belongs to the technical field of sanding machine shell processing devices. Background Art

[0002] In order to ensure that the corresponding parts (motor, driving wheel, driven wheel, handle, etc.) of the handheld belt sander shell can be accurately installed after processing, the processing materials of the belt sander shell need to be accurately machined by machine tools, and tooling is required for positioning during this process. If the workpiece is positioned by conventional tooling such as manual locking, the positioning efficiency is not high on the one hand, and the positioning accuracy is poor on the other hand.

[0003] In the prior art, the workpiece can be positioned and fixed more accurately by combining pre-positioning with hydraulic clamping, and in order to realize the processing of multiple surfaces and multiple angles of the workpiece, the tooling needs to drive the workpiece to rotate at corresponding angles. For example, a hydraulic clamping and positioning mechanism for a workpiece with application number 202321112679.4 can drive the push block to move to one side through the contraction of the hydraulic cylinder piston rod, so that the distance between the two concave clamps can be reduced and the workpiece can be clamped and positioned, and can be rotated 180°. However, it positions the workpiece in the form of a pair of concave clamps, and its clamping area is limited, which may cause uneven force on the entire clamping mechanism during rotation, and may also cause the workpiece to be relatively offset between a pair of concave clamps, resulting in inaccurate positioning. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1.
