[0026] The assembly component 4 includes an electromagnetic adsorber 41, which is fixedly installed at the center of the inner end face of the receiving groove 2 and located at the bottom of the protective baffle 3.

A positioning frame 412 is fixedly installed on the outer side of the two first guide rail slides 411, and a positioning frame 412 is fixedly installed on both sides of the top surface of the positioning frame 412. A first electric cylinder 413 is provided, with a first piston push rod 414 mounted at the center of its bottom end. A limit seat 415 is fixedly mounted on the bottom end face of the first piston push rod 414. The bearing seat to be tested is placed on top of the anti-scratch pad 49, so that the inner axis of the bearing seat is parallel to the testing shaft 6. The protective tube 45 provides good protection for the connecting cable 46. When the electromagnetic adsorber 41 is working, the electromagnetic adsorption plate 48 is energized through the connecting cable 46 and the conductive plate 47, so that... Two electromagnetic adsorption plates 48 can magnetically fix the bearing seat on the top of the anti-scratch pad 49. At the same time, the first electric guide rail 410 on the outside of the detection bracket 43 works, causing the first guide rail slide 411 to drive the positioning frame 412 to move to the outside of both sides of the bearing seat. The first electric cylinder 413 on the end face of the positioning frame 412 works, causing the first piston push rod 414 to push the limiting top seat 415 down until the bottom end face of the limiting top seat 415 is pressed and fixed against the two end faces of the bearing seat, thereby fixing the bearing seat on the inside of the detection bracket 43.
[0027] The protective baffle 3 has a protective through hole in the center of its end face, and an insulating sleeve 42 is fixedly installed inside the protective through hole. The outer wall of the protective tube 45 is fitted and connected to the inner wall of the insulating sleeve 42.

The two sides of the testing shaft 6 are respectively inserted into the center of the two annular locking frames 56, and one end of the locking screw 58 passes through the locking screw hole 57 and is fitted to the top of the outer wall of the testing shaft 6. After the testing shaft 6 passes through the inner hole of the bearing seat, the two ends of the testing shaft 6 are... After being inserted into the annular locking frame 56, the locking screw 58 in the center of the locking screw hole 57 is tightened, so that the bottom of the locking screw 58 is pressed against the outer wall of the detection shaft 6, thereby fixing the detection shaft 6 inside the two annular locking frames 56. The second electric guide rails 52 at the top of the two guide rail brackets 51 work simultaneously, causing the second guide rail slide 53 to move in the same direction. Since the bearing seat is fixed, the detection shaft 6 is driven to press against one end face of the inner hole of the bearing seat, thereby facilitating the pressure test of the inner walls on both sides. When the second electric cylinder 54 at the top of the second guide rail slide 53 works, the second piston push rod 55 can drive the annular locking frame 56 to move up or down, which can drive the detection shaft 6 to press against the top and bottom of the inner hole of the bearing seat, thereby facilitating the pressure test of the top and bottom inner walls of the inner wall. The pressure test component 5 and the detection shaft 6 are used to perform pressure tests on the inner hole of the bearing seat in different directions, making the test convenient and quick.
