Embodiment 1

[0015] Such as figure 2 As shown, a connecting device of a linear sliding mechanism includes a cylinder 1, a connecting rod 3', and a connecting block 2. The cylinder 1 is connected to the connecting rod 3' through the connecting block 2', and the connecting block 2' is The side is provided with a U-shaped card slot, which is positioned and clamped with the connecting rod 3' through the arc surface.

[0016] Described connecting rod 3 ' head is provided with connecting groove, and this connecting groove is made up of mutually vertical vertical groove 31 and horizontal groove, makes connecting rod head form two blocks matching with described U-shaped groove.

[0017] The connecting block 2' is in the shape of "earth", and a U-shaped slot is formed between the bottom block 21 and the middle block 22, and the bottom block is snapped into the vertical groove 31 of the connecting rod.

Abstract

The invention relates to a connecting device for a linear sliding mechanism. The connecting device comprises an air cylinder, a connecting rod and a connecting block, wherein the air cylinder is connected with the connecting rod through the connecting block; two sides of the connecting block are provided with U-shaped clamping grooves; the clamping grooves are clamped with the connecting rod in a locating manner through arc surfaces. Compared with the prior art, the connecting device has the advantages of high adaptability, low damage to a guide rod of a piston, long service life and the like.

Description

technical field [0001] The invention relates to an automobile body welding equipment, in particular to a connection device of a linear sliding mechanism. Background technique [0002] In the automobile industry, in the body-in-white welding equipment, the linear sliding mechanism is more and more widely used. Whether it is in the positioning of the body-in-white workpiece or the switching mechanism of the fixture, the linear sliding mechanism is increasingly needed. It is composed of cylinder, linear guide rail and so on. [0003] In the original linear sliding mechanism, the commercially available cylinder used, the joint 2 is too simple, figure 1 It is an existing connection mode, which is composed of a piston cylinder 1, a joint 2 and a connecting rod 3. When the joint 2 and the connecting rod 3 have an offset angle, the piston in the cylinder will have an offset force, so that the piston does not move on the center line, causing the piston to tilt. It is easily damage...
