clamping mechanism

Abstract

The invention discloses a clamping mechanism, which includes a housing. A connecting rod 1 is arranged at one corner of the housing. One end of the connecting rod 1 is provided with a fixing pin. One end of the fixing pin is fixedly arranged on one side of the inner wall of the housing. The other end of the fixed pin is connected to one end of the connecting rod one, and the connection point is point A, and the other end of the connecting rod one rotates to connect one end of the connecting rod two, and the connection point is point B, and the connecting rod two and the three connecting rods reach While in a straight line state, the connecting rod 3 is in contact with the fine-tuning bolt 2. At this time, the dead point or non-return point is reached, the cylinder cannot be pushed up, and the pressing work is completed; after the connecting rod is in a locked state, it can reach the dead point at a specific position and automatically The lock state has the characteristics of non-return; it can be adapted to the state of clamping the workpiece after the air source is suddenly lost, to protect the safety of machine tools, tools, workpieces and personnel. Easier layout into workbenches and fixture clusters.

Description

technical field [0001] The invention relates to the field of fixture equipment, in particular to a clamping mechanism. Background technique [0002] At present, most of the industrial automatic pressing devices use the cylinder as the power source to complete the pressing of the workpiece. In most working environments, there are dust, solid, liquid, and high-temperature cutting chips and other harsh factors, resulting in unprotected The foreign matter entering between the piston rod and the sealing ring will cause damage to the cylinder and reduce the life of the cylinder; most of the current structure of the integral compression device does not achieve a large swing compression function in the range of short strokes, resulting in the current working compression device. The overall volume is large, and it cannot be flexibly arranged in a limited worktable, and the pressing work cannot be continued after losing the air source; the pressing device in the current market does no...

Problems solved by technology

[0004] The purpose of the present invention is to provide a clamping mechanism to solve the problems of dust, solid state, liquid state, and high-temperature cutting exhaust in most working environments that most of the current industrial automatic pressing devices use cylinders as the power source to complete the pressing of workpieces. Due to the influence of harsh factors such as chips, the cylinder is damaged and the service life is reduced due to foreign matter entering between the unprotected piston rod and the sealing ring; at present, most of the integral compression device structures do not achieve a large swing in the range of short strokes Compression function, resulting in the current working compression device has a large overall volume, cannot be flexibly arranged in a limited work surface, and cannot continue to compress after losing the air source; the current market compression device does not have its own The adjustment function; in the actual adjustment and debugging process, it takes up a lot of staff working time
