Description

Technical Field

[0001] The utility model relates to the technical field of automatic welding machines, in particular to a clamp for automatic welding machines. Background Art

[0002] Automatic welding machine is an automatic welding machine based on motor control technology, single-chip microcomputer control technology, PLC control technology and numerical control technology. The automatic welding machine is mainly composed of automatic workpiece loading and unloading mechanism, automatic workpiece station conversion mechanism, automatic workpiece clamping mechanism, workpiece welding process automation system and system integration control.

[0003] The existing welding machine clamps are only suitable for welding parts with relatively regular shapes. When encountering irregular welding parts, they cannot be clamped and fixed well, which easily causes the position of the welding parts to shift. In addition, the existing clamps cannot rotate, so different surfaces of the welding parts cannot be welded. Manual operation is required, which reduces work efficiency. Therefore, it is necessary to improve the existing devices to meet actual needs. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a clamp for an automatic welding machine, which has the advantages of adapting to welding parts of different regular shapes and facilitating the adjustment of the angles of welding parts, thereby solving the above-mentioned technical problems.

[0008] Preferably, the clamping assembly includes a base rod, a telescopic rod, a spring and a clamping rod, the base rod is fixedly installed on the inner side end of the clamping frame, and the telescopic rod is movably installed on the side end, the spring is sleeved on the outer wall of the base rod and the telescopic rod, and the clamping rod is fixedly installed on the side end.

[0009] Through the above technical solution, when the side end of the clamping rod contacts the welded part, part of the clamping rod is squeezed and drives the telescopic rod to move into the clamping frame. At this time, the spring is compressed. By setting multiple groups of clamping rods, irregularly shaped welded parts can be clamped, thereby improving the applicability of the device body.

[0010] Preferably, a rubber pad is fixedly mounted on the side end of the clamping rod.

[0011] Through the above technical solution, by providing the rubber pad, the clamping wear degree of the welded parts can be reduced.

[0012] Preferably, an electric telescopic rod is symmetrically fixedly installed on the top of the base, and a bracket is fixedly installed on the top of the electric telescopic rod.

[0013] Through the above technical solution, the welded part is placed on the top of the bracket, and the electric telescopic rod is started. The electric telescopic rod drives the welded part to move upward, and directly moves the two side ends of the welded part to the center position of the clamping assembly to avoid the welded part being too heavy and too large, which may cause the staff to be unable to match the physical strength.

[0014] Preferably, the bracket is in a "concave" shape, and a sponge pad is fixedly installed on the top.

[0015] Through the above technical solution, when the welded part falls accidentally, the bracket can provide certain support for the welded part. At the same time, the sponge pad can be provided to increase the cushioning force of the welded part and prevent the welded part from falling and causing damage to the device body.

[0016] Compared with the prior art, the utility model provides a clamp for an automatic welding machine, which has the following beneficial effects:

[0017] 1. The utility model places the welding part on the top of the bracket, starts the electric telescopic rod, the electric telescopic rod drives the welding part to move upward, directly moves the two side ends of the welding part to the center position of the clamping assembly, starts the motor one, the motor one drives the bidirectional screw to rotate, the rotation of the bidirectional screw drives the two sets of sliders to move relative to each other, until the two sets of clamping assemblies clamp and fix the welding part, and starts the motor two, the motor two drives the rotating shaft to rotate, the rotation of the rotating shaft drives the clamping frame to rotate, and the rotation of the clamping frame rotates the fixed welding part, so that welding work can be performed on different surfaces of the welding part, thereby improving work efficiency.

[0018] 2. The utility model sets up multiple groups of clamping components. When the side ends of the clamping rods contact the welding parts, part of the clamping rods drive the telescopic rods to move inside the clamping frame after being squeezed. At this time, the springs are compressed, so that welding parts with irregular shapes can be clamped. When the welding parts are released, the springs drive the telescopic rods and the clamping rods to move outward until they return to their original state. When the welding parts fall accidentally, the bracket can provide certain support for the welding parts. At the same time, the sponge pads can be provided to increase the buffering force for the welding parts and prevent the falling of the welding parts from causing damage to the device body.
