Welding clamp for chair support

Abstract

A welding clamp for a chair support comprises a clamp base plate, supporting legs, a bottom backup plate and a clamp assembly; the supporting legs are installed on the two sides of the clamp base plate; the bottom backup plate is installed on the supporting legs; the clamp base plate is provided with an objective table, and the objective table is used for placing the chair support; chair legs are arranged on the objective table and are pressed to the objective table from a base; the two ends of the chair legs downwards deviate from the middle part to be close to the bottom backup plate; an output end of a telescopic driver is connected with a clamping block and used for driving the clamping block to move in a resettable mode; a chair seat clamp is installed on the clamp base plate, and a clamping block of the chair seat clamp is used for pressing the base to the chair legs, so that the chair legs are fixed on the objective table; and chair leg clamps are installed on the supporting legs, and clamping blocks of the chair leg clamps are used for pressing the chair legs to the bottom backup plate. The welding clamp can be used for fixing the chair support and clamping the chair legs and the base of the chair support respectively, so that the chair support can be machined conveniently, and the stability of the chair support during machining is improved.

Description

technical field [0001] The invention relates to the technical field of chair processing devices, in particular to a welding fixture for a chair bracket. Background technique [0002] Generally, the chair frame of the chair mainly includes the chair legs and the base, and some of them also have a chair back frame for installing the back cushion; the chair frame often needs to be completely fixed during the processing to ensure that the processing position is accurate during processing; In the existing technology, it is common to apply pressure to the chair manually or through a simple external object. This method is still easy to loosen during the actual processing of the chair; and in the prior art, some parts are also fixed to the chair bracket by the clamp, but the clamp The shape of the main frame of the chair is not specifically designed, and the main frame of the chair is still easy to loosen. Contents of the invention [0003] The object of the present invention is ...
