Synchronous compressing device of inverted T-shaped workpiece

Abstract

The invention provides a synchronous compressing device of an inverted T-shaped workpiece, and belongs to the technical field of clamp equipment. The synchronous compressing device comprises a left clamping assembly, a right clamping assembly and a synchronous driving assembly. A left driving cam and a right driving cam of the synchronous driving assembly are symmetrically and rotatably arranged on the two sides of a supporting base. A left chain wheel and a right chain wheel are connected through a chain. The left clamping assembly and the right clamping assembly are symmetrically arranged on the two sides of the supporting base. The middle end of a left pressing plate of the left clamping assembly is hinged to the upper end of a left rocking rod. A left pushing rod can be arranged on a left pushing rod support in a sliding upward and downward mode. A left pushing rod supporting lug is hinged to the left end of the left pressing plate. A left supporting rolling wheel is attached to the left driving cam. The middle end of a right pressing plate of the right clamping assembly is hinged to the upper end of a right rocking rod. A right pushing rod can be arranged on a right pushing rod support in a sliding upward and downward mode. A right supporting rolling wheel is attached to the right driving cam. According to the synchronous compressing device, the two sides of the lower end of the inverted T-shaped workpiece are synchronously clamped, deviation of the inverted T-shaped workpiece in the compressing process is effectively avoided, and the clamping stability is good.

Description

technical field [0001] The invention relates to the technical field of fixture equipment, in particular to a synchronous pressing device for inverted T-shaped workpieces. Background technique [0002] A fixture is a device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position for construction or inspection. 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. For example, machine tool fixtures, welding fixtures, inspection fixtures, assembly fixtures, etc., among which machine tool fixtures are the most common. When processing a workpiece on a machine tool, in order to make the surface of the workpiece meet the technical requirements of the size, geometric shape, and positional accuracy with other surfaces specified in the drawing, the workpiece must be installed (positioned) and clamped (clamped) before processing. . ...

AI Technical Summary

Problems solved by technology

In the processing of inverted T-shaped workpieces, there are many fixtures for inverted T-shaped workpieces. Generally, they rely on clamping both sides of the lower end of inverted T-shaped workpieces. However, this type of fixtures cannot simultaneously clamp both sides. The tightening process will cause the workpiece to shift, resulting in the deviation of the clamping position, which will seriously affect the clamping effect
