Vertical clamping device

Abstract

The invention discloses a vertical clamping device which comprises a clamp body. A hydraulic chuck is arranged in the clamp body. A spring collet is contained in the hydraulic chuck and is internally provided with a containing groove which is used for containing a to-be-clamped workpiece. By means of the vertical clamping device, the workpiece in the vertical clamping device is clamped firmly, and the clamping work efficiency is relatively high.

Description

technical field [0001] The invention relates to a clamping device for clamping a workpiece, in particular, a vertical clamping device for clamping a workpiece with a cylindrical configuration. Background technique [0002] Usually, the workpiece to be processed needs to be clamped and fixed to fix its position before processing. On the one hand, the clamping operation is to make the workpiece obtain the correct position relative to the machine tool and the tool; The position changes, and the processing operation should not be performed, so that the processed workpiece is scrapped. [0003] Further, the commonly used workpiece clamping method in the industry may be to directly clamp the workpiece to the operating machine table, or to clamp the workpiece through a special clamping fixture. [0004] see figure 2 As shown, it illustrates a vertical clamping method that uses a special fixture to clamp the workpiece to be processed. Wherein the workpiece 30 to be processed is ...

AI Technical Summary

Problems solved by technology

This method of using the three-jaw chuck 32 to clamp the workpiece 30 to be processed, although its clamping effect is relatively tight, but because it is a manual operation, it requires relatively high labor requirements.

[0005] Specifically, since the above-mentioned clamping method is manually operated, in order to ensure the firmness of the clamping, the manual labor intensity is relatively large, and the manual clamping skills are required to be high.

In addition, the time required for each clamping operation is relatively long

Moreover, the time consumption of each clamping operation is not fixed because of the manual operation

[0006] In addition, since the three-jaw chuck is directly clamped on the surface of the clamped workpiece, it will also produce certain clamping marks on the clamped surface of the clamped workpiece, which will affect the appearance of its surface.

[0007] The superposition of the above factors makes the work efficiency of this clamping method relatively low, the reliability is not high, and it also affects the appearance of the clamped workpiece.
