Description

Technical Field

[0001] The utility model relates to a robot guide rail stopping device, belonging to the technical field of robots. Background Art

[0002] The stop position control of the robot on the guide rail is very important. Most of the existing guide rail limiters use travel switches to control the position of the robot. The roller on the top of the robot is installed in the T-slot in the guide rail. When the robot moves, the roller is arranged along the length of the T-slot to limit the movement trajectory of the robot. In order to facilitate the stepless adjustment of the position of the travel switch, a strip groove connected to the T-slot is generally opened on the top of the guide rail, so that the contact part of the travel switch extends through the strip groove into the T-slot. When the roller on the top of the robot squeezes the contact part of the travel switch, the circuit of the drive device that controls the movement of the robot is cut off. However, opening a strip groove on the guide rail will reduce the overall strength of the guide rail, so it is necessary to design a robot guide rail stop device that improves the structural strength of the guide rail with a strip groove.

Two travel switches 6 for controlling whether the robot moves are arranged on the upper side of the guide bar 1, wherein the contact part of the travel switch 6 passes through the strip groove 8 and extends into the T-slot 2. A connecting plate 11 is installed on the top of the travel switch 6, so that the lower end of the connecting plate 11 is connected and fixed with a cover sleeve arranged on the side of the travel switch 6, and then the screws connected with the thread on the side of the cover are turned to limit the relative position of the cover and the travel switch 6 by using the screws connected with the thread on the side of the cover, and a screw arranged parallel to the strip groove 8 is inserted in the circular hole opened on one side of the connecting plate 11. Rod 9, the lower ends of the positioning plates 10 connected and fixed at both ends of the screw 9 are connected and fixed to the guide bar 1, and the positioning plates 10 play the role of connecting the screw 9 and the guide bar 1. The connecting plates 11 are provided with nuts 12 threadedly connected to the screw 9 on both sides along the length direction of the screw 9. The spacing between the two travel switches 6 is adjusted along the length direction of the strip groove 8, and then the positions of the two connecting plates 11 on the screw 9 are also changed. When the spacing between the two travel switches 6 meets the needs of the robot's stop position, the nuts 12 on both sides of the connecting plates 11 are used to limit the relative position of the connecting plates 11 and the screw 9, so as to realize the convenient adjustment of the position of the travel switch 6.
