Description

Technical Field

[0001] The invention relates to the technical field of pipe fitting detection and assembly equipment, and in particular to an automatic comprehensive detection and assembly equipment for pipe fitting sealing rings. Background Art

[0002] The package shape and inner cavity of stainless steel compression fittings are currently inspected by naked eyes, the inner diameter is measured by go / no-go gauges, and the internal sealing rings are assembled manually. This requires the cooperation of multiple employees, with low overall efficiency and high labor costs. Therefore, with the advancement of technology, pipe fitting internal sealing ring assembly equipment has emerged, which can automatically load products, visually inspect the outer dimensions, and physically inspect the inner holes. Pipe fittings can be loaded and assembled with multiple sealing rings at one time before being taken off the production line, integrating the inspection and assembly links of stainless steel compression fittings, improving the comprehensiveness and accuracy of inspection, and reducing enterprise labor costs.

[0003] It should be noted that when assembling the assembly equipment, a small micro air compressor is needed to output high-pressure gas to provide power for the various components of the assembly equipment. However, during the use of the air compressor, due to the complex use environment, or the quality of the air compressor and many other reasons, the air compressor may be blocked. At this time, although the air compressor continues to run, it cannot output air. However, since the assembly equipment is an automated operation equipment, the workers do not always observe the assembly equipment during work. The blockage of the air compressor will cause partial functional failures, making it impossible to complete the assembly of pipe fittings or assemble the pipe fittings into defective products, affecting the production quality of the pipe fittings, and will also cause the temperature of the air compressor to rise sharply, causing the air compressor to burn out at the least. Under extreme conditions, the air compressor may even explode, posing a huge safety hazard. Summary of the invention

Tube 702, and then the high-pressure gas enters the outlet pipe 11 through the switch box 701; it should be noted that if a malfunction occurs during the operation of the air compressor 6, resulting in blockage and inability to discharge gas, resulting in a relatively low air pressure in the switch box 701, at this time, under the rebound force of the torsion spring 710, the support shaft 709 drives the closing plate 704 to reset, and the closing frame 703 is closed. At the same time, under the return force of the return spring 713, the extrusion push plate 711 is pulled to reset, and the extrusion push plate 711 drives the closing cover 715 to move through the buffer tube 716, so that the high-pressure gas in the other switch box 701 enters the switch box 701 with low air pressure through the auxiliary air pipe 702, ensuring that there is high-pressure gas in the outlet pipe 11; Furthermore, when the air pressure in the switch box 701 is reduced, so that the torsion spring 710 drives the support shaft 709 to rotate, the support shaft 709 drives the rotating plate 705 to rotate, and the rotating plate 705 rotates to squeeze the lifting frame 803 to move, and the lifting frame 803 slides vertically in the lifting slot 804, and the lifting frame 803 drives the disconnection frame 801 to move, and then the disconnection frame 801 drives the power plug 10 to be unplugged, so that the air compressor 6 is powered off, avoiding the problem of overheating and damage caused by continuous idling of the air compressor 6; Furthermore, in the process of the disconnection frame 801 moving upward, the linkage frame 913 is driven to move, and the movement of the linkage frame 913 drives the driving shaft 912 to move, and the driving shaft 912 moves in the driving hole 911, so that the linkage frame 913 drives the stop frame 908 to move, and then the stop frame 908 slides horizontally in the moving groove 910, and the stop frame 908 is separated from the stop groove 909. At this time, under the rebound force of the two telescopic springs 907, the two pull-down seats 905 are driven to move, so that the pull-down seats 905 drive the explosion-proof cover 903 to unfold, thereby avoiding the problem of the air compressor 6 exploding and damaging the automatic detection assembly machine 1 under extreme circumstances.
