[0026] Please refer to Figures 1-9 , the present utility model provides a technical solution:
[0027] An inspection machine for detecting the quality of bearings, including a clamping assembly 1 and an inspection device 2. The inspection device 2 is arranged on the top of the clamping assembly 1. The clamping assembly 1 includes a chassis 101, a column 102, a top plate 103, a chuck 104, a sleeve 105, a connecting pipe 106, a cylinder 107, an upper gasket 108, a lower gasket 109, a silica gel pad 110, a pressing frame 111, a limiting rod 112, a first stepping motor 113, a threaded rod 114, an insertion plate 115, a flexible contact block 116, and a groove plate 117. The top end of the chassis 101 is fixedly provided with a column 102, a limiting rod 112, and a first stepping motor 113. The top end of the column 102 is fixedly provided with a top plate 103.

The groove plate 117 is slidably arranged in an embedded manner with the groove formed in the insertion plate 115. Through the above settings, when the pressing frame 111 moves upward, the top end of the silica gel pad 110 is in close contact with the bottom of the upper gasket 108. The silica gel pad 110 moves upward to squeeze the oil liquid inside the cylinder 107. The top of the oil liquid squeezes the insertion plate 115, forming a state where the groove plate 117 is slidably arranged in an embedded manner with the groove formed in the insertion plate 115.
[0029] The detection device 2 includes a bench 21, a display 22, a cylinder device 23, a strip board 24, a second stepping motor 25, an insert block holder 26, and a torque sensor 27. The display 22 is fixedly arranged inside the bench 21, the cylinder device 23 is fixedly arranged at the top of the bench 21, the strip board 24 is fixedly arranged at the top of the cylinder device 23, the second stepping motor 25 is fixedly arranged at the bottom of the strip board 24, the bottom end of the second stepping motor 25 is fixedly arranged with the top end of the insert block holder 26 through a coupling, the torque sensor 27 is fixedly arranged on the outside of the insert block holder 26, and the rear end of the top plate 103 is fixedly arranged with the bench 21.

[0030] The insertion plate 115 is slidably arranged in a fitting manner inside the sleeve 105, and the bottom end inside the cylinder body 107 is in contact and fit with the pressing frame 111. Through the above settings, the sleeve 105 forms a sliding limit structure for the inside of the insertion plate 115, and the contact between the pressing frame 111 and the bottom of the cylinder body 107 forms a limit structure.
[0031] The outer side of the threaded rod 114 is rotatably arranged in a threaded manner inside the bottom end of the pressing frame 111, and the outer side of the limiting rod 112 is slidably arranged inside the bottom end of the pressing frame 111. Through the above settings, it is convenient to drive the pressing frame 111 to move vertically by the first stepping motor 113.
[0032] Working process: The present utility model provides a detection machine for detecting the quality of bearings, which can perform torque detection on the frictional resistance of bearings, and the device main body is convenient for centrally clamping and limiting the bearings.
[0033] The display 22, the cylinder device 23, the first stepping motor 113, the second stepping motor 25, and the torque sensor 27 arranged in this device are all electrically connected to an external power supply. The cylinder device 23, the first stepping motor 113, and the second stepping motor 25 arranged above are all controlled and processed by an external PLC controller. The value of the torque sensor 27 is transmitted to the inside of the display 22 through an information line, and the data is processed and displayed by the software inside the display 22.
[0034] The chassis 101, the top plate 103, the chuck 104, the sleeve 105, the insertion plate 115, and the flexible contact block 116 are all horizontally arranged. Place the bearing between the top of the top plate 103 and the inside of the chuck 104, as Figure 5 、 Figure 6 and Figure 7 shown. The inside of the sleeve 105, the connecting pipe 106, and the cylinder body 107 arranged in this device are filled with oil. The top of the silica gel pad 110 and one end of the insertion plate 115 away from the flexible contact block 116 are both in contact with the oil. The sleeve 105 is a rigid silica gel sleeve, and the insertion plate 115 and the inner wall of the sleeve 105 form a good sealing and leakage prevention effect.
[0035] The first stepping motor 113 starts to drive the threaded rod 114 to rotate clockwise. The outer side of the threaded rod 114 is rotationally arranged with internal threads at the bottom end of the pressing frame 111. The outer side of the limiting rod 112 is slidably arranged with the internal part at the bottom end of the pressing frame 111. At this time, the pressing frame 111 moves upward until the top end of the silica gel pad 110 is in contact with the bottom of the upper sealing pad 108. The silica gel pad 110 moves upward to extrude the oil in the cylinder body 107. The top of the oil extrudes the insertion plate 115. The groove plate 117 is fitted and slid with the groove formed in the insertion plate 115 until the flexible contact block 116 abuts against and fits with the outer ring of the bearing.
[0036] The cylinder device 23 starts to drive the strip plate 24, the second stepping motor 25, the insert block holder 26 and the torque sensor 27 to move downward synchronously until the insert block holder 26 is fitted and placed in the slot formed in the inner ring of the bearing. The second stepping motor 25 starts to drive the insert block holder 26 and the torque sensor 27 to rotate, and the frictional resistance of the bearing is detected through the torque sensor 27.
[0037] Similarly, the first stepping motor 113 starts to drive the threaded rod 114 to rotate counterclockwise. At this time, the pressing frame 111 moves downward until the bottom end of the silica gel pad 110 is in contact with the top of the lower sealing pad 109. The silica gel pad 110 moves downward. At this time, the oil in the cylinder body 107 flows back downward. At this time, the insertion plate 115 resets under the action of the oil flowing back. The groove plate 117 is fitted and slid with the groove formed in the insertion plate 115 until the flexible contact block 116 is disengaged from the outer ring of the bearing.
[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
