Description

Cylinder handle

Technical Field

The utility model relates to the technical field of automobile production line, especially, relate to a cylinder handle structure.

Background

In an automobile manufacturing factory, an automobile welding production line is a key in automobile manufacturing, and various tool fixtures in the welding production line are heavy in weight of a welding line. The basic structure of the welding fixture comprises a bedplate, a support, an L plate, a reference pin, a reference surface, a clamping mechanism (an air cylinder, a clamping arm, a U-shaped limiting block and the like) and the like. Welding jig had both guaranteed product quality, had improved productivity and had alleviateed intensity of labour, nevertheless be in order to satisfy part technological requirement, the while is compatible various product motorcycle types again, and welding jig design often can have a plurality of clamping mechanism, and a lot of needs are artifical to utilize cylinder handle operation to carry out the part location among the clamping mechanism and place, and in the limited space of platen, cylinder handle operating space can reduce or even interfere. In order to ensure the operation space of the cylinder handle in the clamping mechanism, the gap space between the clamping mechanisms needs to be fully utilized, and meanwhile, the welding is not influenced.

SUMMERY OF THE UTILITY MODEL

Based on the consideration, the utility model discloses the coexistence of multiple clamping mechanism of anchor clamps has fully been considered in the invention, and the problem such as cylinder handle operating space is limited. The cylinder handle structure eliminates the defects of coexistence of various clamping mechanisms, insufficient handle operation space and the like, fully utilizes the limited bedplate, ensures the operation space of the cylinder handle, realizes effective operation of workers, does not influence welding, fully utilizes the space, ensures the product quality, lightens the labor intensity of the workers and the like. The specific technical scheme is as follows:

a cylinder handle comprises a cylinder on a clamp clamping mechanism, a front-end square connecting block connected with a front-end positioning structure of the cylinder, and a rear-end square connecting block fixed on the cylinder through four bolts, wherein a groove structure embedded with a U-shaped limiting block is designed in the middle of the rear-end square connecting block, and the U-shaped limiting block is arranged on the inner side of the connecting block with the groove; the rear-end square connecting block, the U-shaped limiting block and the connecting block are connected through bolts; the cylinder is fixed on a connecting block with a groove through a bolt, an L-shaped connecting block II is fixed on a square connecting block at the rear end through a bolt, and is connected with the L-shaped connecting block I through a bolt; the U-shaped connecting block and the L-shaped connecting block II are respectively provided with a convex block, the U-shaped connecting block and the L-shaped connecting block II are connected with the corresponding convex blocks by a shaft with a cotter pin, and the two convex blocks are connected with the working handle in a welding mode.

Furthermore, on the movable rod of cylinder with all be equipped with the screw hole of predetermineeing the degree of depth on the circular post of activity, be connected cylinder and the circular post of activity through the bolt.

Furthermore, all the connecting blocks in the structure are effectively connected through bolts of various types; the movable circular column connecting block is preset according to the process requirement and the effective movement of the air cylinder.

The utility model has the advantages that: 1. through various clamping mechanisms under the coexistence of various vehicle types, the space gap of a cylinder in the clamping mechanism is fully utilized, various connecting structures are ingeniously designed, and the purpose of realizing operation without influencing welding is achieved; 2. this through add U type stopper between design handle and the cylinder, guaranteed the stability (do not let its swing) when anchor clamps cylinder and handle are in the tight operating mode of clamp, guarantee validity, the accuracy of cylinder activity.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

a cylinder handle comprises a cylinder 2 on a clamp clamping mechanism, a front-end square connecting block 1 connected with a front-end positioning structure of the cylinder, and a rear-end square connecting block 3 fixed on the cylinder 2 through four bolts, wherein a groove structure embedded with a U-shaped limiting block 6 is designed in the middle of the rear-end square connecting block 3, and the U-shaped limiting block 6 is arranged on the inner side of a connecting block 5 with a groove; the rear-end square connecting block 3, the U-shaped limiting block 6 and the connecting block 5 are connected through bolts; the cylinder is characterized by further comprising a movable circular column 4 connected with the cylinder 2, an L-shaped connecting block I7 fixed on a connecting block 5 with a groove through a bolt, an L-shaped connecting block II8 fixed on a rear-end square connecting block 3 through a bolt, a U-shaped connecting block 10 and an L-shaped connecting block I7 connected through a bolt; the U-shaped connecting block 10 and the L-shaped connecting block II8 are respectively provided with a lug 9, the U-shaped connecting block 10 and the L-shaped connecting block II are connected with the corresponding lugs 9 by a shaft 11 with a cotter pin, and the two lugs are connected with a handle 12 in a welding mode.

On the movable rod of cylinder 2 with all be equipped with the screw hole of predetermineeing the degree of depth on the circular post 4 of activity, be connected cylinder 2 and the circular post 4 of activity through the bolt.

The working principle is as follows: an operator presses a manual operation button, grasps a movable handle by hands, utilizes a cylinder to move, and propels the structure, so that the U-shaped limiting block is matched and clamped, the clamp is used for positioning and placing parts, the product is welded, the clamp is pressed down to complete the pneumatic button, the structure returns to the original position automatically, and the boss of the U-shaped limiting block is separated from the groove.
