Adjustable clamp for machine tool

Abstract

The invention discloses an adjustable clamp for a machine tool. The adjustable clamp comprises a clamp body, a rubber pad, a base, a spring, a hydraulic cylinder, a through hole, a rotating clamping block, clamping plates, a screw rod, a rectangular through opening, a push rod and a movable clamping block. A bottom plate is arranged at the bottom of the clamp body. The base is arranged on the topface of the rubber pad. The spring is arranged in a blind hole. The hydraulic cylinder is arranged on one side of the base. The rotating clamping block is installed above the through hole. The clamping plates are installed on the side faces of the rotating clamping block. The rectangular through opening is formed in the middle portion of the top face of the base. The push rod is arranged in the rectangular through opening. The movable clamping block is arranged at the top end of the push rod. By means of the adjustable clamp for the machine tool, the rotating clamping block is arranged, the clamping plates different in shape are installed on the side face of the rotating clamping block, during adjustment, the rotating clamping block is rotated, and the clamping plates of the movable clamping block are replaced; and only one clamping block needs to be replaced, the clamping block replacing time is shortened, the work efficiency is improved, the rubber pad and the spring are used for absorbing vibration generated during machine tool running, and the operation precision of a machine tool is improved.

Description

technical field [0001] The invention relates to the technical field of machine tool clamps, in particular to an adjustable clamp for machine tools. Background technique [0002] Adjustable fixture is a special fixture that can replace or adjust components. When processing workpieces on machine tools, in order to make the surface of the workpiece meet the technical requirements of the size, geometric shape and mutual position accuracy with other surfaces specified in the drawing, before processing The workpiece must be installed and clamped. Compared with the general fixture, the adjustable fixture can reduce the time of changing the fixture and improve the work efficiency when processing workpieces of different shapes. [0003] However, most of the current adjustable fixtures are to replace the splints of the two clamping blocks, and then clamp them with different shapes of splints. It takes a long time to replace the two clamping blocks, which affects work efficiency, and t...

[0003] However, most of the current adjustable fixtures are to replace the splints of the two clamping blocks, and then clamp them with different shapes of splints. It takes a long time to replace the two clamping blocks, which affects work efficiency, and the vibration of the machine tool is relatively large, and the clamp has no vibration reduction function.
