Technical Field
[0001] The invention relates to the technical field of bearing assembly, and in particular to a high-precision bearing assembly device and an assembly method thereof. Background Art
[0002] Tapered roller bearings are a type of rolling bearing that uses tapered rollers (i.e. rolling elements) in conjunction with inner and outer rings to withstand large radial and axial loads. The rollers of tapered roller bearings are tapered, and this structure allows the rolling surface and the contact surface of the inner and outer rings to be in line contact rather than surface contact. This can improve the load-bearing capacity and is particularly suitable for bearing large axial loads.
[0003] In the assembly process of tapered roller bearings, the accuracy of roller installation is crucial because it directly affects the performance, life and working stability of the bearing. The rollers of tapered roller bearings usually have a certain contact angle and are usually designed to optimize load distribution. When the rollers are not installed accurately, the contact angle will change, affecting the load capacity and running performance of the bearing.

A pick-up and place rack is slidably arranged in the detection seat, and a push rod is arranged on the pick-up and place rack. The push rod is used to push the tapered roller bearing under detection. A swing rod is rotatably arranged on the pick-up and place rack, and an adsorption head is arranged on the swing rod. The adsorption head removes the tapered roller with abnormal working state.

The multiple sets of tapered rollers on the retainer fit with the detection column, and then the two sets of telescopic rods are driven to reset, the clamping column is driven to descend, the clamping column drives the pressing plate to press the inner ring, and the fixed frame is driven to clamp. The clamping column slides on the column, and the two sets of fixed frames clamp the inner wall of the inner ring. At this time, the clamping column and the inner ring are fixed, and the clamping column is driven to rotate on the adjusting frame, and the clamping column drives the inner ring to rotate. At this time, the working state of the tapered roller is judged according to the reading of the pressure sensor on the detection column. When an abnormal tapered roller appears, the clamping column is driven to slide on the adjusting frame. Since the clamping column and the inner ring are fixed at this time, the clamping column drives the inner ring to fall off the retaining frame, and then the pick-up and place frame is driven to slide on the detection seat, and the pick-up and place frame drives the swing rod to rotate along the axis of the detection seat, and drives the swing rod to rotate on the pick-up and place frame. The swing rod drives the adsorption head to approach a group of tapered rollers with problems. When the adsorption head is attached to the tapered roller, the tapered roller is removed, and then the fault is manually checked and a new tapered roller is placed.
[0020] If there is no problem with the tested tapered roller bearing, first drive the clamping column to reset, then drive the push rod to slide on the pick-and-place frame, and the push rod will push the installed inner ring, cage and tapered roller out of the testing seat. At this time, drive the two sets of telescopic rods to clamp the tested inner ring, cage and tapered roller, drive the adjustment frame to slide on the assembly seat, and the adjustment frame drives the tested inner ring, cage and tapered roller to rise, then drive the placement plate to slide on the assembly seat, and the placement plate drives the outer ring to align with the tested inner ring, cage and tapered roller, reset the two sets of telescopic rods, and the telescopic rods will place the tested inner ring, cage and tapered roller in the outer ring to complete the installation of the tapered roller bearing.

[0039] A method for using an assembled bearing of a high-precision bearing assembly device comprises the following steps: S1. Place the tapered rollers 403 in a feeding mechanism. The feeding mechanism sorts multiple groups of tapered rollers 403 and places them in a retaining frame 402.
[0040] S2. Filling assembly 1 places the inner ring 401 on the retaining frame 402 to complete the assembly of the inner ring 401, the retaining frame 402 and the tapered roller 403.
[0041] S3. The assembly component 2 places the assembled inner ring 401, retainer 402 and tapered roller 403 on the placement ring 302 through the clamping mechanism for inspection.
[0042] S4. When the inner ring 401 is rotated, the faulty tapered roller 403 is determined according to the value of the pressure sensor on the detection column 303.
[0043] S5. The abnormal tapered roller 403 is taken out by the picking mechanism on the detection component 3.
[0044] S6. The clamping mechanism places the inner ring 401, the retaining frame 402 and the tapered roller 403 that have been inspected on the outer ring 404.
[0045] Working principle: When working, the retaining frame 402 is placed at the lower end of the limiting frame 111, the feeding frame 108 is driven to move on the base 101, the feeding frame 108 is aligned with the filling position, the limiting frame 127 is driven to release the blocking of the feeding frame 108, and the locking frame 125 is driven to release the blocking of the discharge port 124. At this time, the tapered roller 403 falls on the discharge rod 120 through the discharge port 124, and the cam 116 and the cam 2 116 are driven to move. 7 rotates, cam 116 drives the vibration plate 114 to knock the feed hopper 123, cam 2 117 drives spring 2 119 to slide back and forth on the discharge rod 120, and the tapered roller 403 falls between the limiting frame 111 and the retaining frame 402 through the feed pipe 109 and the feed frame 108, and at the same time drives the limiting frame 111 to rotate, and the limiting frame 111 drives the retaining frame 402 to rotate, completing the filling of all the vacancies on the retaining frame 402. The accuracy of the position of the tapered roller 403 in the retaining frame 402 is improved by controlling the positioning column 112 and the straightening frame 113. After the filling of the tapered roller 403 is completed, the feed frame 108 is driven to reset, and the limiting frame 127 and the locking frame 125 are driven to move, respectively completing the blocking of the feed frame 108 and the discharge port 124, and driving the two groups of fixed frames 110 to move away from each other. The fixed frame 110 clamps a group of inner rings 401, and the mounting plate 104 is driven to rotate on the supporting frame 102, and the lifting frame 105 is driven to slide on the mounting plate 104. The lifting frame 105 places a group of inner rings 401 above the limiting frame 111, and the mounting plate 104 is driven to reset, and the lifting frame 106 is driven to slide on the base 101. The lifting frame 106 drives the retaining frame 402 and the tapered roller 403 to rise, and the installation of the inner ring 401, the retaining frame 402 and the tapered roller 403 is completed.
[0046] When the lifting frame 106 lifts the installed inner ring 401, retaining frame 402 and tapered roller 403, the adjusting frame 202 is driven to slide on the assembly seat 201, and the telescopic rod 207 is driven to slide in the adjusting frame 202. The telescopic rod 207 drives the two sets of clamping rings 208 to align with the installed inner ring 401, retaining frame 402 and tapered roller 403, and drives the two sets of clamping rings 208 to approach each other to complete the clamping of the tapered roller bearing 4. The lifting frame 106 is driven to reset and the telescopic rod 207 is driven to reset. After the inner ring 401, the retaining frame 402 and the tapered roller 403 are aligned with the placement ring 302, and the inner ring 401, the retaining frame 402 and the tapered roller 403 are placed on the placement ring 302. The multiple groups of tapered rollers 403 on the retaining frame 402 are fitted with the detection column 303. Then, the two groups of telescopic rods 207 are driven to reset, the clamping column 205 is driven to descend, the clamping column 205 drives the pressing plate 206 to press the inner ring 401, and the fixing frame 209 is driven to move upward. The clamping column 205 slides on the adjusting frame 202, and the two sets of fixing frames 209 clamp the inner wall of the inner ring 401. At this time, the clamping column 205 and the inner ring 401 are fixed, and the clamping column 205 is driven to rotate on the adjusting frame 202. The clamping column 205 drives the inner ring 401 to rotate. At this time, the working state of the tapered roller 403 is judged according to the reading of the pressure sensor on the detection column 303. When an abnormal tapered roller 403 appears, the clamping column 205 is driven to slide on the adjusting frame 202. Since the clamping column 205 and the inner ring 401 are fixed at this time, The clamping column 205 drives the inner ring 401 to fall off the retaining frame 402, and then drives the pick-up and placement frame 304 to slide on the detection seat 301, the pick-up and placement frame 304 drives the swing rod 306 to rotate along the axis of the detection seat 301, drives the swing rod 306 to rotate on the pick-up and placement frame 304, and the swing rod 306 drives the adsorption head 307 to approach a group of problematic tapered rollers 403. When the adsorption head 307 is in contact with the tapered roller 403, the tapered roller 403 is removed, and then the fault is manually checked and a new tapered roller 403 is placed.
[0047] If the tested tapered roller bearing 4 has no problem, first drive the clamping column 205 to reset, then drive the push rod 305 to slide on the pick-and-place frame 304, and the push rod 305 will push the installed inner ring 401, retaining frame 402 and tapered roller 403 out of the testing seat 301. At this time, drive the two sets of telescopic rods 207 to clamp the tested inner ring 401, retaining frame 402 and tapered roller 403, and drive the adjustment frame 202 to slide on the assembly seat 201. The adjustment frame 202 with The inner ring 401, retainer 402 and tapered roller 403 that have been tested are moved upward, and then the placement plate 203 is driven to slide on the assembly seat 201. The placement plate 203 drives the outer ring 404 to align with the inner ring 401, retainer 402 and tapered roller 403 that have been tested. The two sets of telescopic rods 207 are reset, and the telescopic rods 207 place the inner ring 401, retainer 402 and tapered roller 403 that have been tested in the outer ring 404, completing the installation of the tapered roller bearing 4.
