[0002] Bearings are a fundamental component of modern industrial machinery, typically consisting of rings, balls, and cages. The rings are further divided into outer and inner rings, with the outer ring featuring a sealing groove. For bearing outer ring inspection, the inner diameter and sealing groove are key testing items. Existing automated testing equipment generally has two independent testing mechanisms to inspect the outer ring inner diameter and sealing groove separately, requiring two separate inspections. Therefore, some have proposed that the inspection of the sealing groove and outer ring inner diameter could be integrated into a single testing process, significantly improving efficiency. Thus, a multi-stage inspection mechanism capable of simultaneously inspecting the sealing groove and outer ring inner diameter is needed. Summary of the Invention

[0015] Example: See Figures 1 to 2 As shown, the multi-detection mechanism for the sealing groove of the ring on the automated testing line includes two sets of symmetrical detection components 10. The detection components 10 are respectively mounted and connected to the grippers of the finger-clamping cylinder. The upper end face of the mounting adjustment block 11 has several bottom threaded holes 113 formed therein. The mounting adjustment block 11 is fixed to the grippers of the finger-clamping cylinder by bolts. The detection component 10 includes the mounting adjustment block 11 and the detection claw 12. Several trapezoidal and vertically distributed positioning grooves 111 are formed on one end face of the mounting adjustment block 11. The bottom surface of the device has an adjustment groove 112 that extends through the other end face of the mounting adjustment block 11. A locking bolt is inserted into the adjustment groove 112 and screwed onto the detection claw 12. The stroke of the finger-clamping cylinder during the detection operation of this application is fixed. The position of the detection claw 12 on the mounting adjustment block 11 is adjusted to match the detection part on the collar. During the detection, proximity switch sensors are respectively installed on the front and rear sides of the mounting adjustment block 11. When the finger-clamping cylinder drives the detection component 10 to move for detection, triggering the proximity switch sensor indicates that the product is qualified. If it is not triggered, it is unqualified. The detection claw 12 includes a vertical claw bar 121. A trapezoidal positioning block 1211 is formed at the upper end of the claw bar 121. The positioning block 1211 is inserted into the adjustment groove 112 of the mounting adjustment block 11 and has a threaded hole 1213 corresponding to the locking bolt. Longitudinal cylindrical integrated seats 122 are respectively provided on the opposite end faces of the two sets of claw bars 121. One end of the integrated seat 122 has a D-shaped connecting post 1223, which is inserted and fixed to the claw bar 121. At the lower end of 21, the other end of the integrated base 122 is formed with a horizontally flat extension lug 1221, and the end of the extension lug 1221 is formed with a horizontally arc-shaped sealing groove detection head 1222; a horizontally longitudinal inner diameter probe 123 is inserted into the upper part of the extension lug 1221, and the head of the inner diameter probe 123 extends out of the extension lug 1221; a locking screw 125 is screwed onto the integrated base 122, and the end of the locking screw 125 presses against the inner diameter probe 123.
[0016] The outer contour of the positioning groove 111 on the mounting adjustment block 11 is consistent with the outer contour of the positioning block 1211 at the upper end of the claw rod 121; the positioning groove 111 can restrict the longitudinal rotation of the claw rod 121 in the vertical plane; the positioning groove 111 is linearly and evenly distributed on the mounting adjustment block 11.
[0017] Figure 3 , 4 As shown, the lower end of the claw 121 is formed with a connecting block 1212, and a longitudinal positioning hole 1214 is formed on the connecting block 1212. The connecting post 1223 is inserted into the positioning hole 1214 of the connecting block 1212. A set screw 124 is screwed onto the connecting block 1212. The end of the set screw 124 presses against the connecting post 1223. The specific clamping part of the set screw 124 is on the outer wall of one side of the plane of the connecting post 1223, which facilitates the setting of the integrated base 122.
[0018] Figure 3 , 4 As shown, the lower part of the claw rod 121 is formed with an inclined slot 1215 that communicates with the positioning hole 1214. An inclined connecting rod 126 is inserted into the inclined slot 1215. Connecting sleeves 1261 are formed at the upper and lower ends of the connecting rod 126. A longitudinal adjusting bolt 127 is screwed onto the connecting sleeve 1261 at the upper end of the connecting rod 126. A limiting sleeve 128 is screwed onto the end of the adjusting bolt 127. The heads of the limiting sleeve 128 and the adjusting bolt 127 abut against the opposite end faces of the claw rod 121. The tail end of the inner diameter probe 123 extends out of the integrated seat 122 and is inserted and fixed onto the connecting sleeve 1261 at the lower end of the connecting rod 126. After loosening the locking screw 125, the position of the inner diameter probe 123 can be adjusted by rotating the adjusting bolt 127, which facilitates the movement of the inner diameter probe 123.
[0019] The detection components 10 are provided with two sets of longitudinal guide posts 20, one upper and one lower. The mounting adjustment blocks 11 of the detection components 10 are respectively formed with longitudinal guide holes 114. One end of the guide post 20 is inserted and fixed in the guide hole 114 of one set of mounting adjustment blocks 11, and the other end is inserted and fixed in the guide hole 114 of the other set of mounting adjustment blocks 11. The guide post 20 can ensure that the two sets of detection components 10 are at the same height, which facilitates the installation and debugging of the detection components 10. At the same time, the guide post 20 can be staggered, that is, two guide posts 20 are respectively fixed on the mounting adjustment blocks 11 and inserted into adjacent mounting adjustment blocks 11.
[0020] A ring positioning auxiliary component 30 is provided between the two sets of detection components 10. The ring positioning auxiliary component 30 includes a horizontal reference plate 31. A vertical connecting seat 311 is formed on the upper surface of the middle part of the reference plate 31. The connecting seat 311 is inserted between the two sets of mounting adjustment blocks 11 and abuts against the mounting adjustment blocks 11 respectively. A vertical limiting groove 312 is formed on the connecting seat 311 and penetrates the upper surface of the connecting seat 311. A guide post 20 is inserted into the limiting groove 312 of the connecting seat 311. A horizontal limiting bolt 37 is screwed to the upper end of the connecting seat 311 and is inserted into the limiting groove 312. The lower part of the connecting seat 311 has a slot 313 formed through the lower end face of the reference strip 31. An adjusting screw sleeve 33 is inserted into the slot 313. The connecting seat 311 on both sides of the adjusting screw sleeve 33 has insertion holes. A D-shaped rotating shaft 32 is inserted into the adjusting screw sleeve 33. The two ends of the rotating shaft 32 pass through the insertion holes of the connecting seat 311 and are respectively fitted with positioning sleeves 34. The positioning sleeves 34 abut against the two side walls of the connecting seat 311. The two ends of the rotating shaft 32 are respectively formed with screws 32. Guide grooves 314 are formed on the reference plates 31 on both sides of the reference plate 31. V-shaped clamps 35 with opposite groove openings are respectively abutted on the lower end surfaces of the reference plates 31. Guide blocks 351 are formed on the upper end surfaces of the V-shaped clamps 35. The upper end of the guide block 351 passes through the guide grooves 314 of the reference plate 31 and is inserted and fixedly connected to a transverse inner threaded sleeve 36. The inner threaded sleeve 36 is screwed onto the screws 32 at both ends of the rotating shaft 32. The detection component 10 of this application requires the use of standard bearing rings during detection. To establish a testing benchmark, the bearing race needs to be centered between the two sets of testing claws 12 during the debugging process. During debugging, first activate the clamping cylinder to separate the two sets of mounting adjustment blocks 11. Then, loosen the limiting bolt 37 to open the slot of the limiting groove 312. Insert the bearing race positioning auxiliary component 30 between the mounting adjustment blocks 11. Next, move the bearing race positioning auxiliary component 30 upwards, placing the bearing race below the benchmark strip 31 of the bearing race positioning auxiliary component 30. Then, by rotating the adjusting screw sleeve 33, the V-shaped clamp 35 moves, ultimately causing the bearing race to move and clamp it. Then, by adjusting the position of the claw rod 121, the sealing groove testing head 1222 on the integrated seat 122 is inserted into the sealing groove of the race. Next, fix the position of the claw rod 121, and then adjust the position of the inner diameter probe 123 so that the head of the inner diameter probe 123 rests against the inner wall of the race. Finally, remove the bearing race positioning auxiliary component 30, and the product can be tested.
[0021] The midpoint of the rotating shaft 32 and the central axis of the inner diameter probe 123 are both in the same vertical plane to ensure that the clamped bearing ring is centered.
[0022] The thickness of the adjusting screw sleeve 33 is equal to the width of the groove 313; the width of the guide groove 314 is equal to the distance between the front and rear ends of the guide block 351; the width of the guide groove 314 on the connecting seat 311 is equal to the diameter of the guide post 20, and the length of the guide groove 314 is greater than the distance between the two sets of guide posts 20.
[0023] Working principle: This structure is a multi-detection mechanism for the sealing groove of the ring on an automated testing line, such as... Figure 1As shown, the sealing groove detection head 1222 and inner diameter probe 123 on the detection claw 12 are arranged facing outwards, mainly for detecting the sealing groove and inner diameter of the outer ring (if the positions of the two sets of detection components 10 are interchanged, the sealing groove detection head 1222 and inner diameter probe 123 on the detection claw 12 can be arranged facing inwards and outwards, which can detect the outer diameter and sealing groove of the inner ring with the outer sealing groove). The detection of the sealing groove of the outer ring mainly detects whether the sealing groove exists, and the dimensional accuracy requirement of the bottom surface of the sealing groove is not high; while the inner diameter of the outer ring is the assembly mating dimension, which requires higher accuracy. Therefore, the integrated sealing groove detection head 1222 detects the presence of a sealing groove, and its inner diameter probe 123 detects its inner diameter size.
[0024] The embodiments described are illustrative of the invention and are not intended to limit the invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the invention; therefore, the scope of protection of the invention should be as set forth in the claims.
