Description

Quick replacement device of anchor clamps for hydraulic machining

Technical Field

The invention belongs to the technical field of machine tool fixtures, and particularly relates to a quick replacement device for a fixture for hydraulic machining.

Background

The machine tool clamp is a device used for clamping a workpiece and guiding a cutter on a machine tool, is a clamp specially designed for a certain procedure of a certain workpiece, has the characteristics of compact structure, rapid operation, convenience and labor saving, can ensure higher processing precision and production efficiency, and is suitable for fixed products and large-batch production. It is in contact with the positioning references of the workpiece for determining the correct position of the workpiece in the holder, thus ensuring a correct relative position of the workpiece with respect to the tool and the machining movement of the machine tool during machining.

When the traditional machine tool clamping device is used:

1. the clamp at the upper end of the clamp can only be fixed at one position generally, so that the clamp is influenced by the size of the workpiece when the workpiece is clamped, the clamp needs to be adjusted, the existing clamp cannot be adjusted at will and can only be integrally replaced to adapt to workpieces with different sizes, different clamps need to be prepared when the clamp is used, and more time and energy are consumed when the clamp is installed and replaced, so that the clamp is very inconvenient to use.

2. Because conventional anchor clamps connecting plate adopts the bolt to fix, has leaded to the anchor clamps size that has adjusted, when changing the connecting plate, needs use tool to carry out the dismouting to the bolt of connecting plate upper end, and some bolts are fixed tighter when the installation, cause very inconvenient when dismantling to the use of device produces the influence.
