Description

Technical Field

[0001] This invention belongs to the field of mechanical technology, specifically relating to automatic bearing assembly equipment and processes. Background Technology

[0002] Traditional bearing assembly equipment uses manual feeding, which can easily lead to incomplete bearing placement and misalignment between the bearing and the press head. This creates an asymmetrical load transmission path during press-fitting, causing the press-fitting force to act abnormally on the inner ring of the bearing through the rolling elements, resulting in Brinell indentations on the inner ring raceway. Furthermore, existing processes suffer from discrete operation; after pressing the upper bearing, the workpiece must be flipped to another station for pressing the lower bearing, or an additional dual-press system is required, making it impossible to complete the synchronous pressing of upper and lower bearings at a single station. These defects cause the bearings to fail due to fatigue spalling of the inner ring raceway after long-term vehicle operation, ultimately leading to transmission system inefficiency and overall machine malfunction.

[0003] No effective solution to the above problems has yet been found. Summary of the Invention

Detailed Implementation

[0053] The present invention will be further described below. Those skilled in the art should understand through the following embodiments that these embodiments are not intended to limit the technical solution of the present invention, but merely to fully illustrate how to implement it.

[0054] Examples, such as Figure 1-4 As shown, the automatic bearing assembly equipment includes a workbench 1, a tray 6 slidably disposed on the double roller conveyor of the workbench 1, a first positioning device 8 and a second positioning device 9 located between the double roller conveyor of the workbench 1, a lower bearing picking device 2 located on a frame on one side of the workbench 1, a bearing pressure head 7 located on a frame on the top of the workbench 1, above the second positioning device 9, a backing device 5 located below the second positioning device 9, a lower bearing feeding device 3 located between the first positioning device 8 and the second positioning device 9, and an upper bearing feeding device 4 disposed on one side of the workbench 1, opposite to the lower bearing picking device 2.

[0055] The upper bearing, lower bearing and C3 clutch assembly are carried on pallet 6 and sent to the material handling station and pressing station respectively.

[0056] The lower bearing picking device 2 picks up the lower bearing on the tray 6 and sends the lower bearing to the lower bearing feeding device 3. The lower bearing feeding device 3 receives the lower bearing and transfers it to the backing device 5.

[0057] The bearing pressure head 7 includes an upper bearing pressure head 71 and a lower bearing pressure head 72. The upper bearing pressure head 71 and the lower bearing pressure head 72 are alternately pressed by an independent drive mechanism. After the lower bearing pressure head 72 completes the pressing, it moves laterally to one side of the pressing position to provide operating space for the upper bearing pressure head 71.

[0058] The upper bearing feeding device 4 clamps the upper bearing on the tray 6 and temporarily stores it for use by the upper bearing pressure head 71.

[0059] The lower bearing pressure head 72 presses the lower bearing into the inner hole of the lower bearing of the C3 clutch assembly; the upper bearing pressure head 71 clamps the upper bearing of the upper bearing feeding device 4 and presses the upper bearing into the inner hole of the upper bearing of the C3 clutch assembly.

[0060] The counterweight 5 is used to support the C3 clutch assembly and cooperates with the upper bearing pressure head 71 and the lower bearing pressure head 72 to complete the pressing of the upper and lower bearings.

[0061] The first positioning device 8 lifts the pallet 6 to the material picking position, and the second positioning device 9 lifts the pallet 6 to the pressing position.

[0062] Specifically, during material handling, the pallet 6 slides along the roller conveyor to above the first positioning device 8. The first positioning device 8 lifts the pallet 6 to the material handling position. The upper bearing feeding device 4 moves to the material handling position, grabs the upper bearing on the pallet 6, and returns to its original position for temporary storage. Simultaneously, the lower bearing picking device 2 moves to the material handling position, grabs the lower bearing, places the lower bearing on the lower bearing feeding device 3, and then returns to its original position. The lower bearing feeding device 3 delivers the lower bearing to the positioning seat 5051 on the backing device 5, awaiting pressing.

[0063] During pressing, pallet 6 slides along the roller conveyor to the pressing station. At this time, only the C3 clutch assembly remains on pallet 6 (the upper and lower bearings have been removed). The second positioning device 9 rises, lifting pallet 6 to the pressing position to ensure that the C3 clutch assembly is aligned with the positioning shaft 505. The counterweight device 5 lifts up, jacking up the C3 clutch assembly and stabilizing it in the pressing position. The lower bearing pressing head 72 moves to the pressing position, pressing the lower bearing on the counterweight device 5 into the C3 clutch assembly. After pressing, the lower bearing pressing head 72 moves to one side, and the upper bearing pressing head 71 moves to the pressing position, pressing the upper bearing into the C3 clutch assembly. After pressing, the upper bearing pressing head 71 and the lower bearing pressing head 72 return to their original positions.

[0064] Multiple pallets 6 can be set up. When pressing the upper and lower bearings, another pallet 6 can carry the upper and lower bearings and the C3 clutch assembly into the material picking position to complete the gripping of the upper and lower bearings and wait to enter the pressing position to achieve continuous operation.

[0065] The lower bearing material handling device 2, the lower bearing feeding device 3, the upper bearing feeding device 4, the tray 6, the bearing pressure head 7, the first positioning device 8, and the second positioning device 9 are all existing technologies, and their structures will not be described in detail here.

[0066] like Figure 5-10As shown, the anti-reverse device 5 includes a support mechanism, which includes a bracket 526, on which a first support plate 501 and a second support plate 502 are fixed.

[0067] The anti-backing device 5 also includes a lifting mechanism and a wedge clamping mechanism. The wedge clamping mechanism is set on the first support plate 501, and the lifting mechanism is set on the second support plate 502. When the lifting mechanism rises to the pressing position and the upper bearing is pressed, the wedge clamping mechanism can move laterally to the bottom of the lifting mechanism to wedge the lifting mechanism.

[0068] The lifting mechanism includes a third support plate 518, which is mounted on a second support plate 502. A positioning shaft 505 is provided in the mounting hole of the third support plate 518. A fixed bracket 517 and a second spacer 513 are sleeved on the positioning shaft 505. The fixed bracket 517 is snapped onto the third support plate 518. The second spacer 513 is located on the fixed bracket 517, and a baffle 512 is fixed at the upper end of the second spacer 513. A first elastic element 507 for support and buffering is provided between the positioning shaft 505 and the fixed bracket 517. A positioning seat 5051 is provided on the top of the positioning shaft 505, and the lower bearing is placed on the positioning seat 5051.

[0069] Two sets of guide shafts 506 are provided on the third support plate 518. An outer bushing 511 is movably connected to the guide shaft 506. The outer bushing 511 is sleeved on the fixed bracket 517 and the second spacer 513. A second elastic element 514 for support and buffering is provided between the guide shaft 506 and the outer bushing 511. The two sets of guide shafts 506 provide precise guidance for the movement of the outer bushing 511.

[0070] The lower end of the outer bushing 511 is symmetrically fixed with a first anti-block 515 and a second anti-block 516.

[0071] The positioning shaft 505 is also provided with an anti-rotation pin 519, which passes through the outer bushing 511 and restricts the rotation of the outer bushing 511.

[0072] The lifting mechanism also includes an optical axis 503 symmetrically arranged between the first support plate 501 and the second support plate 502. The optical axis 503 passes through the bracket and is sleeved with a first spacer 504 on its outer side. The upper end of the optical axis 503 is fixedly connected to the third support plate 518. A counter-pressure cylinder 508 is fixedly connected to one side of the third support plate 518. The counter-pressure cylinder 508 drives the optical axis 503 to lift and lower through the third support plate 518.

[0073] The wedge clamping mechanism includes a wedge clamping fixing block 520 disposed on one side of the lifting mechanism. The wedge clamping fixing block 520 is provided with a symmetrical first wedge clamping block 509 and a second wedge clamping block 510. The contact surfaces of the first wedge clamping block 509 and the second wedge clamping block 510 are respectively matched with the shapes of the contact surfaces of the first anti-block 515 and the second anti-block 516.

[0074] The end of the wedge-tightening block 520 away from the lifting mechanism is connected to a wedge-tightening cylinder 521. A connecting plate 522 is fixed on the wedge-tightening cylinder 521, a guide plate 523 is fixed on the connecting plate 522, and a guide block 524 is fixed on the guide plate 523. Symmetrical limiting blocks 525 are fixed on the first support plate 501, and the guide block 524 is slidably disposed in the guide groove between the two limiting blocks 525.

[0075] The wedge cylinder 521 pushes the wedge fixing block 520 to move laterally to below the lifting mechanism. At this time, the first wedge block 509 and the second wedge block 510 are located under the first anti-block 515 and the second anti-block 516, respectively.

[0076] When the lower bearing is press-fitted, the backing cylinder 508 drives the lifting mechanism to the press-fitting position. At this time, the wedge clamping mechanism is in its original position, the outer bushing 511 can move and does not have a backing function. The lower bearing press head 72 presses down the positioning shaft 505. When the lower bearing press head 72 contacts the baffle 512, the lower bearing press-fitting position is reached, and the baffle 512 provides backing support.

[0077] When the upper bearing is press-fitted, the wedge clamping mechanism moves laterally to below the lifting mechanism, the first anti-block 515 and the second anti-block 516 are wedge-fitted, and the outer bushing 511 is locked. At this time, the outer bushing 511 plays an anti-blocking role, which, together with the upper bearing press head 71, completes the upper bearing press-fitting.

[0078] Specifically, when pallet 6 enters the pressing station, the second positioning device 9 lifts pallet 6 to the pressing position;

[0079] Press-fitting the lower bearing: The backing cylinder 508 drives the lifting mechanism to move the lower bearing upward to the press-fitting position. At this time, the C3 clutch assembly is lifted, and the wedging mechanism is in its original position. During the press-fitting process, the outer bushing 511 is not wedged. When the lower bearing press head 72 moves downward, the outer bushing 511 moves downward with the lower bearing press head 72 and does not provide backing support. The baffle 512 provides backing support. Under the action of the lower bearing press head 72, the lower bearing is pressed into the inner hole of the lower bearing of the C3 clutch assembly. After the lower bearing is pressed into place, the lower bearing press head 72 moves upward, and the outer bushing 511 returns to its original position under the action of the spring. The lower bearing press-fitting is completed. The lower bearing press head 72 moves laterally to one side of the press-fitting position to make way for the upper bearing press head 71.

[0080] Upper bearing press-fit: The wedge-tightening cylinder 521 drives the wedge-tightening mechanism to move laterally to the lower end of the lifting mechanism, reaching the wedge-tightening position. The upper bearing press head 71 moves to the press-fit position. Since the wedge-tightening mechanism is in the wedge-tightening position, the first wedge-tightening block 509 and the second wedge-tightening block 510 are located below the first anti-blocking block 515 and the second anti-blocking block 516, wedge them together, and the outer bushing 511 is locked, which plays the role of pressing and anti-blocking the upper bearing press head 71. Under the action of the outer bushing 511 and the upper bearing press head 71, the upper bearing is pressed into the inner hole of the upper bearing of the C3 clutch assembly. After the upper bearing is press-fitted in place, the upper bearing press head 71 returns, the wedge-tightening mechanism returns to its original position, the outer bushing 511 is released, the lifting mechanism moves down to its original position, and the tray 6 moves out of the work station, completing the entire press-fitting process.

[0081] like Figure 1-12 As shown, the automated bearing assembly process implemented using the above bearing assembly equipment includes the material handling step:

[0082] S101. The pallet 6, carrying the upper bearing, lower bearing, and C3 clutch assembly, slides above the first positioning device 8, and the first positioning device 8 lifts the pallet 6 to the material picking position;

[0083] S102. The grippers of the upper bearing feeding device 4 close and clamp the upper bearing on the tray 6; at the same time, the lower bearing picking device 2 moves downward, the grippers open and clamp the lower bearing on the tray 6.

[0084] S103. The tray 6 falls back to its original position along with the first positioning device 8, and the upper bearing and lower bearing separate from the tray 6;

[0085] S104. The upper bearing feeding device 4 moves laterally to below the upper bearing pressure head 71, the upper bearing pressure head 71 moves downward and clamps the upper bearing, and the upper bearing pressure head 71 moves upward with the upper bearing back to its original position.

[0086] At the same time, the lower bearing picking device 2 moves laterally to above the lower bearing feeding device 3, the lower bearing picking device 2 moves downward, and the lower bearing feeding device 3 clamps the lower bearing.

[0087] S105. The upper bearing feeding device 4 grippers open and move laterally back to their original position;

[0088] The grippers of the lower bearing material handling device 2 close, move upward, and then move laterally back to their original position;

[0089] The lower bearing feeding device 3 moves laterally to above the positioning seat 5051 of the anti-collision device 5. The lower bearing feeding device 3 moves downward to place the lower bearing on the positioning seat 5051. The grippers of the lower bearing feeding device 3 open and move laterally back to the original position.

[0090] It also includes the pressing step:

[0091] S201. The C3 clutch assembly enters the pressing station along with the pallet 6. The C3 clutch assembly is located directly above the lifting mechanism. The second positioning device 9 lifts the pallet 6 for positioning.

[0092] S202. The wedge clamping mechanism of the reverse support device 5 is in its original position, the lifting mechanism moves upward to the pressing position, and lifts up the C3 clutch assembly on the tray 6;

[0093] S203. The lower bearing pressure head 72 moves downward to press the lower bearing into the inner hole of the lower bearing of the C3 clutch assembly, thus completing the press-fitting of the lower bearing.

[0094] S204. The lower bearing pressure head 72 is moved laterally to the press-fit position to make way for the upper bearing pressure head 71, and the upper bearing pressure head 71 is moved laterally to the press-fit position.

[0095] S205. The wedge clamping mechanism of the anti-reverse device 5 moves laterally to the lower part of the lifting mechanism, the wedge clamping mechanism wedges the lifting mechanism, the outer bushing 511 is locked, and at the same time the upper bearing pressure head 71 moves downward to press the upper bearing into the inner hole of the upper bearing of the C3 clutch assembly.

[0096] S206. The upper bearing pressure head 71 and the lower bearing pressure head 72 return to their original positions, the wedge clamping mechanism moves horizontally back to its original position, and the lifting mechanism moves downward back to its original position;

[0097] S207. The tray 6 falls and leaves with the second positioning device 9, and the pressing is completed.

[0098] Specifically, during the pressing step, the material taking steps S101 to S103 are completed simultaneously.

[0099] The technical solution of this invention, through the coordinated design of the reverse-mount device and the bearing pressure head, allows the assembly of upper and lower bearings to be completed simultaneously at a single pressing station, eliminating the need for additional pressing stations or a second press, saving equipment space and reducing the number of tooling, thus lowering manufacturing costs. At the same time, the automatic assembly process eliminates the workpiece flipping and repetitive positioning steps in traditional step-by-step assembly, improving single-piece assembly efficiency and production capacity, and effectively reducing the labor intensity of operators while achieving continuous operation.
