Clamping fixture for cover plate

Abstract

The invention discloses a clamping fixture for a cover plate and relates to a clamp. The clamping fixture for the cover plate comprises a substrate, clamping mechanisms and adjusting mechanisms, wherein each clamping mechanism comprises a pressing plate, a pull rod and a driving piece; one end of each pressing plate is a clamping end while the other end of each pressing plate is a force transfer end; a strip-shaped hole which is connected with the upper end of the pull rod is formed in the middle of each pressing plate; the lower end of each pull rod is connected with the substrate in a sliding way; each driving piece is also connected to the lower end of the corresponding pull rod; each clamping mechanism also comprises a wedge block which is fixed to the substrate; a wedge face is arranged on each wedge block; the force transfer end of each pressing plate is in contact with the wedge face; each adjusting mechanism comprises a limit rod and a limit plate; each limit plate is connected with one end of the corresponding limit rod; the other end of each limit rod is provided with a circular stop block; each limit rod is connected to the wedge block in a sliding way; each limit plate is in contact with the force transfer end of the corresponding pressing plate; a spring is arranged between each wedge block and the circular stop block of the corresponding limit rod; and the adjusting mechanisms have the effect of resetting the pressing plates. The clamping fixture for the cover plate has the advantages that the clamping effect is good and the applicable range is wide.

Description

technical field [0001] The invention relates to a clamp, in particular to a clamping clamp for a cover plate. Background technique [0002] The fixture is a device used to fix the processing object in the process of mechanical manufacturing so that it can occupy the correct position for construction or testing; the existing fixtures are mainly divided into general fixtures and special fixtures; the three-jaw chuck is a typical general fixture. Its application range is wide; and the special fixture is a fixture specially designed for the processing of a certain part; but whether it is a general fixture or a special fixture, it is usually clamped from one side of the workpiece at the same time, so that The clamping effect is not good, especially in the case of large vibration, it is easy to loosen; and for some irregular workpieces, especially for some cover plates, the shapes are different, but they are all flat, so the design for such workpieces Special fixtures need to inv...
