Apparatus for robot switching sled supports

Abstract

The invention discloses a device for skidding support switching through a robot, and relates to the technical field of automobile production equipment manufacturing. The device comprises a connectingbase and a stirring rod, and a sliding device is connected between the connecting base and the stirring rod and comprises an upper-layer connecting plate with the upper end face connected with the connecting base, and a lower-layer sliding plate with the lower end face provided with a stirring rod frame, wherein the stirring rod frame is connected with the stirring rod. Two sliding blocks are symmetrically arranged on the upper end face of the lower-layer sliding plate. A sliding rail connected with the two sliding blocks is arranged on the lower end face of the upper-layer connecting plate. Sliding block limiting plates are arranged at the two ends of the upper-layer connecting plate. The lower end face of the upper-layer connecting plate is further provided with two screws for installingsprings. Pre-tightening nuts are screwed into the screws by a section of distance, the springs are pre-tightened, and the pre-tightened springs provide reset force in the two sliding directions for the lower-layer sliding plate for skidding support switching. Compared with the prior art, the support switching process can be controllable, impacts on skidding supports and the robot are weak, and the requirement of the robot for automatic skidding support switching can be met.

Description

technical field [0001] The invention relates to the technical field of automobile production equipment manufacturing, in particular to a device for a robot to switch the support of a sliding skid. Background technique [0002] The early automobile factories had relatively single products and fewer product platforms, so the number of car body support points on the skids was relatively small, and there was basically no interference. With the rapid development of the national automobile industry, the product lines of automobile factories are becoming more and more abundant. On the same production line, models with multiple platforms will be produced on the same line, and the skid supports will interfere with each other. It is necessary to design the skid supports as Flip the form of the switch to avoid interference. At present, there are two ways of using the cylinder as the power to switch the sled support and the robot to switch the sled support. Taking the robot switching ...

Problems solved by technology

However, in practical applications, the sum of the machining accuracy of the sled and the accuracy of the running stop position will make the repetitive positioning accuracy of the sled support poor (about ±5mm). The shifting causes the lever to be stuck, causing the robot to overload the alarm; at the same time, because the sensitivity of the robot’s overload alarm is not high, the value of the output force cannot be controlled. Once the above situation occurs, it is easy to cause secondary failures such as damage to the sled
