Robot welding jig for idler bracket

Abstract

The invention relates to a carrier roller bracket robot welding clamp, which comprises a platform, a support plate, a regulating seat, a position limiting arm, an ascending and descending table, an ascending and descending control mechanism, a guide rail, two position limiting plates and a horizontal control mechanism, wherein one end of the support plate is arranged on the platform, the regulating seat is arranged on the non-fixed end of the support plate, the position limiting arm is connected with the regulating seat through a bracket, two ends of the bottom of the ascending and descending table are respectively provided with guide rods, the guide rods pass through the platform, the ascending and descending control mechanism passes through the platform and is connected with the bottom of the ascending and descending table, the guide rail is arranged at the upper surface of the ascending and descending table, the two position limiting plates are arranged on the upper surface of the ascending and descending table through the guide rail and are in opposite arrangement, the horizontal control mechanism is arranged in the ascending and descending table in a penetrating way and is connected with the position limiting plates. The carrier roller bracket robot welding clamp has the advantages that in the use process, the position limiting plates are continually and automatically regulated to find a new clamping force balancing point through the effect of an air cylinder, so that the welding stress is gradually released, and the welding deformation degree of a workpiece is reduced.

Description

technical field [0001] The invention relates to the technical field of cable lead-in of electrical equipment, in particular to a robot welding jig for a roller bracket. Background technique [0002] The idler roller is an important part of the belt conveyor, with many types and large quantities. It accounts for 35% of the total cost of a belt conveyor and bears more than 70% of the resistance, so the quality of the idler roller is particularly important. The role of the idler is to support the conveyor belt and the weight of the material. The operation of idlers must be flexible and reliable. Reducing the friction between the conveyor belt and the rollers plays a key role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor. Although the idler roller is a small part in the belt conveyor, the structure is not complicated, but it is not easy to manufacture high-quality idler rollers. Idlers are generally completed by welding....

Problems solved by technology

Although the idler is a small part in the belt conveyor, the structure is not complicated, but it is not easy to manufacture high-quality idlers

Idlers are generally completed by welding. The "dead" characteristics of the clamping size of traditional welding fixtures lead to excessive stress concentration of the workpiece after welding, which makes the workpiece easily deformed. The deformed workpiece is difficult to take out from the fixture, such as forcibly If it is taken out, it is easy to cause damage such as dents, and if it is serious, it may cause cracks on the workpiece due to excessive stress concentration. The traditional welding fixture can no longer meet the welding process requirements. In the case of sub-manufacturing welding, robot welding workstations and other process technologies are becoming more and more mature. Development and The matching welding fixture tooling is imminent
