Description

Push-pull clamping mechanism without self-locking Technical Field The utility model relates to the technical field of mechanical equipment in the automobile industry, in particular to a non-self-locking push-pull clamping mechanism. Background The non-self-locking push-pull clamping mechanism is a common plane four-bar mechanism. It consists of a frame, two connecting rods and a float. In the mechanism, the frame is relatively fixed, and two side links connected with the frame are all connecting rods, namely, the side links can only do reciprocating swing within a certain angle range. When the existing clamping frame clamps workpieces, clamping blocks are required to be replaced according to the shapes of the workpieces, when the irregular workpieces are required to be clamped, clamping is unstable easily, workpieces with different shapes are difficult to clamp, loosening or shifting easily occurs when the irregular workpieces are clamped, machining precision is reduced, and the clamps or adjusting equipment is required to be replaced frequently. Disclosure of Invention The utility model aims to provide a non-self-locking push-pull clamping mechanism so as to solve the problems in the prior art.
