Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vehicle manufacturing and welding fixture technology, and specifically relates to a quick-change positioning device for identifiable fixtures. Background Technology
[0002] In the automotive manufacturing industry, to improve workstation utilization and save costs, each workstation needs to be equipped with multiple fixtures. Currently, this is usually done manually by checking the labels on the fixtures. However, these labels can be worn down by welding slag, dust, and other factors, leading to errors and misplacement. By adding mechanisms and sensors to the fixtures mechanically, signal recognition can be achieved, and instructions can be issued to the PLC for judgment. This solves the problem and is more accurate and less prone to errors than manual methods. Summary of the Invention

[0009] In order to clearly explain the innovative purpose, technical solution and advantages of this utility model, the technical solution of this utility model will be explained in detail below.
[0010] The figure shows a quick-change positioning device for a recognizable clamp, comprising a beam-column positioning assembly 8 and two main base plates 6 fixed at both ends. The device is characterized by two concave limiting block assemblies 1 symmetrically arranged on the front face of the beam-column positioning assembly 8; two pin positioning assemblies 2 and two circular lifting assemblies 4 arranged on the upper face of the main base plates 6; two planar limiting block assemblies 3 symmetrically arranged between the pin positioning assemblies 2 and the circular lifting assemblies 4; bearing guide plates 5 respectively provided on the inner sides of the two main base plates 6; and a sensor mechanism 7 provided above the beam-column positioning assembly 8. The beam-column positioning assembly 8 consists of a beam 9 and beam corner seats 10. A sensor mechanism fixing plate 13 is welded to the middle of the beam 9, and the beam corner seats 10 are fixed to both ends of the beam 9, with the lower part of the beam corner seats 10 fixedly connected to the main base plates 6. The concave limiting block assembly 1 consists of a first planar limiting block 14, a concave limiting block assembly base plate 15, a concave limiting block fixing block 16, and a concave limiting block 17. Both the base plate 15 and the concave limiting block 17 have concentric through holes 25, in which a first proximity switch 22 is installed. The planar limiting block assembly 3 consists of a second planar limiting block 141, a proximity switch fixing piece 18, and a planar limiting block assembly corner seat 19. The proximity switch fixing piece 18 is mounted on the side of the planar limiting block assembly corner seat 19, and a second proximity switch 221 is mounted on the fixing piece 18. The two pin positioning assemblies 2 and the two circular lifting assemblies 4 are symmetrically arranged on the upper surface of the main base plate 6. The bearing guide plate 5 is elongated and arranged along the front-to-back direction on the main base plate 6. The main base plate 6 has through holes 24 around its perimeter, in which hammer-type anchor bolts 26 are installed for fixing to the ground.
[0011] When the clamp 23 is pushed to the accurate position, the V-shaped limiting block installed on the clamp will engage with the concave limiting block 17; at the same time, the first proximity switch 22 and the second proximity switch 221 are sensed and positioned, and the two pin positioning combination mechanisms 2 and the circular lifting combination mechanism 4 are lifted up. The L-shaped limiting block 20 installed on the clamp will pull and collide with the first plane limiting block 14 and the second plane limiting block 141 of the positioning device when the two pin positioning combination mechanisms 2 and the circular lifting combination mechanism 4 are lifted up (when the clamp is in position but not lifted up, the upper end surface of the L-shaped limiting block 20 installed on the clamp is lower than the lower end surface of the first plane limiting block 14 and the second plane limiting block 141 of the positioning device), forming upper and lower limits, and completing the clamp positioning and fixing.
[0012] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present invention.
