Wedge block type synchronous fixture

Abstract

The invention relates to a wedge block type synchronous fixture. The wedge block type synchronous fixture comprises a base, a driving piece mounted on the base, a wedge block driven by the driving piece, and two clamp bases linked with the wedge block; chutes extending in the length direction of the base are symmetrically formed in the two sides of the top of the base; the clamp bases are slidingly matched in the corresponding chutes; a vertical through hole is formed in the middle part of the base, is positioned between the two chutes, and communicates with the chutes; the driving piece comprises a cylinder block mounted at the bottom of the base, and a piston rod in vertical moving fit in the cylinder block; a driving end of the piston rod extends into the vertical through hole; the wedge block is mounted at the driving end of the piston rod, so that the wedge block is positioned between the two clamp bases; two vertical inclined grooves are oppositely and symmetrically arranged on the sides, towards the wedge block, of the clamp bases; and correspondingly, two vertical inclined buckles matched with the two vertical inclined grooves are arranged on the side, towards the clamp bases, of the wedge block, so that the wedge block is linked with the clamp bases on two sides for approaching or leaving. The wedge block type synchronous fixture is higher in stability and excellent inrigidity.

Description

Technical field [0001] The invention belongs to the field of tooling fixtures, and specifically relates to a wedge-type synchronous fixture. Background technique [0002] The fixture is a process device used to quickly fasten the workpiece during processing, so that the machine tool, cutting tool, and tool can maintain the correct relative position. In other words, the fixture is an indispensable part of mechanical processing. Fixtures are also called fixtures. In a broad sense, in any process in the process, devices used to quickly, conveniently and safely install workpieces can be called fixtures, such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures Among them, machine tool fixtures are the most common, often referred to as fixtures for short. [0003] At present, the commonly used crank-type two-jaw synchronous clamps on the market are prone to defects such as out-of-synchronization, poor stability, and high noise during use. Based on this, t...

AI Technical Summary

Problems solved by technology

[0003] At present, the crank-type two-jaw synchronous clamps commonly used in the market are prone to defects such as out-of-sync clamping, poor stability, and loud noise during use.

Based on this, there are corresponding solutions in the prior art. For example, the patent document whose publication number is CN2613345Y discloses a synchronous clamp. As a result, the structural rigidity of the synchronous fixture is not high, and the stability is average
