A Mechanical Fixture for Rapid Positioning of Circular Workpieces

Abstract

The invention discloses a mechanical clamp capable of quickly positioning circular ring workpieces. The mechanical clamp capable of quickly positioning the circular ring workpieces comprises a supporting plate and a vertical plate. The vertical plate is fixedly installed on the edge side of the surface of the supporting plate, a threaded groove which is used for conducting traction and movement isformed in the surface of the middle of the vertical plate, and a lead screw is arranged inside the threaded groove in a threaded penetration mode. A lock nut is arranged at the top end of the lead screw in a sleeving mode, and a supporting connection plate is arranged at the end of the lead screw in a fixed connection mode through an embedded bearing. A collecting plate is arranged at one end ofthe supporting connection plate in a supporting mode, and multiple positioning grooves are fixedly formed in the surface of the collecting plate. Hydraulic telescoping cylinders are correspondingly and fixedly installed on the surfaces of the multiple positioning grooves, the telescoping ends of the multiple hydraulic telescoping cylinders are connected with mechanical clamps in a driving mode, and the mechanical clamps are correspondingly installed on the reverse side of the collecting plate. The mechanical clamp capable of quickly positioning the circular ring workpieces has the beneficial effects that due to the arranged mechanical clamps, a traction groove, trapezoidal clamping blocks and stretching springs, the positions of the whole trapezoidal clamping blocks are conveniently adjusted, and the fine adjustment is conducted by the traction effect of the hydraulic telescoping cylinders.

Description

technical field [0001] The utility model relates to a fixture, in particular to a mechanical fixture capable of quickly positioning circular ring workpieces, and belongs to the technical field of workpiece processing and positioning. Background technique [0002] Fixture refers to the device used to fix the processing object in the process of mechanical manufacturing so that it can occupy the correct position to accept construction or inspection, also known as fixture. In a broad sense, any process in the process, the device used to install the workpiece quickly, conveniently and safely, can be called a fixture. [0003] The fixture usually consists of a positioning element (to determine the correct position of the workpiece in the fixture), a clamping device, a tool setting guide element (to determine the relative position of the tool and the workpiece or to guide the direction of the tool), and an indexing device (to enable the workpiece to be positioned in one installatio...

AI Technical Summary

Problems solved by technology

[0005] The purpose of this utility model is to provide a kind of mechanical fixture that can quickly locate the ring-shaped workpiece, to solve the problem that the existing mechanical fixture proposed in the above background technology has low automatic clamping accuracy of the circular mechanical workpiece and cannot be mass-produced. The specific clamping process makes it more cumbersome in the daily processing and use process, unable to quickly locate and grab, and can only be picked up manually
