Description

Technical Field

[0001] The present invention relates to the technical field of automobile assembly, and particularly relates to a waterproof wheel hub positioning and assembling device and process. Background Art

[0002] At present, the wheel hub plays an important role in the use of automobiles. After a long time of automobile driving, when the wheel hub needs to be replaced or when the automobile is assembled initially, it is first necessary to align the new wheel hub with the drive shaft of the automobile, that is, to align the mounting holes on the wheel hub with the mating holes on the drive shaft. Then, the bolts at the corresponding positions are manually installed, so that the wheel hub is fixed on the drive shaft. However, the following problems exist in the process of assembling the wheel hub: 1. First, after the wheel hub and the drive shaft are placed, there is no alignment between the wheel hub and the drive shaft, and when manually aligning, the wheel hub is not fixed. Therefore, when the wheel hub rotates, there is a deflection between the wheel hub and the drive shaft, resulting in a slow subsequent assembly process and a low overall assembly convenience.

[0003] 2. Since the wheel hub itself is relatively heavy, when manually installing, it is first necessary to lift the wheel hub to a specified height, then align the wheel hub and the drive shaft and manually assemble them. The steps are relatively cumbersome and labor-consuming in the whole process. Therefore, the installation efficiency of the wheel hub is low while the labor cost increases. Summary of the Invention

[0013] The beneficial effects of the present invention are as follows: 1. In the present invention, the forward shift shaft moves forward and inserts into the mounting holes on the hub and the drive shaft, so that the hub and the drive shaft meet the installation requirements. At the same time, the existing external motor drives the rotating gear to rotate through the gear shaft, thereby adjusting the position of the mounting hole on the hub, so that the mounting hole rotates with the hub by a certain angle to the position directly above the hub axis. And during the assembly process, the forward shift shaft and the mating shaft cooperate with each other to ensure that there is no deflection between the hub and the drive shaft, which is convenient for subsequent assembly and improves the overall convenience.

[0014] 2. The positioning mechanism set in the present invention first positions and clamps the hub and then transports it to the designated position. After that, the hub is aligned with the corresponding drive shaft. At the same time, the assembled mechanism works to fix the hub on the drive shaft through bolts. The meshing between the rotating gear and the gear groove makes the operating shaft rotate synchronously, thereby adjusting the position of the mounting hole on the hub. Therefore, continuous assembly of the mounting holes at different positions on the hub is carried out, improving the work efficiency while reducing the manual participation, that is, reducing the labor cost.

[0015] 3. The adaptive spring set in the present invention makes the positioning plate adaptively rotate during the process of clamping and positioning the hub through the elastic force generated by its own deformation. Therefore, the contact area between the outer arc surface of the positioning plate and the inner ring of the hub increases, improving the stress area during positioning and clamping, and avoiding the problem of damage to the hub by the positioning plate during clamping and positioning.

Detailed implementation mode

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways defined and covered by the claims.

[0027] Refer to Figure 1 , a waterproof wheel hub positioning and assembling device, including a mounting plate 1, a driving shaft 2, a positioning mechanism 3 and an assembling mechanism 4. The mounting plate 1 is vertically placed and is opposite to the driving shaft 2 of the vehicle. The front end face of the mounting plate 1 is sequentially provided with a positioning mechanism 3 and an assembling mechanism 4 from bottom to top, and both the positioning mechanism 3 and the assembling mechanism 4 are located between the mounting plate 1 and the driving shaft 2;

[0028] Refer to Figure 1 , Figure 2 , Figure 6 and Figure 8, the positioning mechanism 3 includes a transverse movement groove. A transverse movement groove extending from left to right is formed on the front end face of the mounting plate 1. A transverse movement plate 30 is slidably arranged in the transverse movement groove. Two rearward movement grooves that are symmetric left and right and extend from front to back are formed on the upper end face of the transverse movement plate 30. A T-shaped block 300 is slidably arranged in the rearward movement groove. A vertical plate 301 located between the mounting plate 1 and the drive shaft 2 is fixedly arranged on the upper end face of the transverse movement plate 30. Two vertical movement grooves 302 that are symmetric left and right and extend from top to bottom are formed on the front end face of the vertical plate 301. Electric sliders are slidably arranged in the vertical movement grooves 302. A placement plate 303 is fixedly arranged on the front end faces of the two electric sliders together. Two symmetric left and right positioning grooves are formed on the front end face of the placement plate 303. A positioning block 304 is slidably arranged in the positioning groove. A connecting plate is fixedly arranged on the front end face of the positioning block 304. A drive gear 305 is rotatably arranged on the front end face of the placement plate 303 through a gear shaft. Rack teeth that are meshed with the drive gear 305 are fixedly arranged on the opposite faces of the two connecting plates. A vertically placed transition plate 306 is fixedly arranged on the front end face of the connecting plate. Two symmetrically arranged upper and lower arc-shaped positioning plates 307 are rotatably arranged on the front end face of the transition plate 306 through a connecting shaft. Plate groups are fixedly arranged on the opposite faces of the two transition plates 306. Each plate group includes two symmetrically arranged upper and lower inclined plates 308. A spring plate opposite to the corresponding positioning plate 307 is fixedly arranged on the front end face of the inclined plate 308. Two symmetrically arranged adaptation springs 309 are arranged on the opposite faces of the spring plate and the corresponding positioning plate 307.

[0029] During operation, first, the vehicle floor and the drive shaft 2 are lifted to a predetermined height by an existing external lifting mechanism. At this time, the transverse movement plate 30 is located at the left position. The hub is manually moved to the designated position and the positioning plate 307 is located inside the inner circle of the hub. Meanwhile, an existing external motor works to drive the drive gear 305 to rotate through the gear shaft. Through the cooperation between the drive gear 305 and the rack teeth, the two rack teeth move away from each other. Therefore, the outer arc-shaped surface of the positioning plate 307 at this time is in close contact with the inner arc-shaped surface of the hub. The hub is clamped and positioned through the cooperation between the four positioning plates 307. Then, the electric sliders in the vertical movement grooves 302 work to lift the hub to the designated height through the placement plate 303 and the transition plate 306 and move the transverse movement plate 30 in the transverse movement groove. Thus, the hub is moved to directly behind the drive shaft 2 through the positioning mechanism 3. The elastic force generated by the deformation of the two corresponding adjacent adaptation springs 309 enables the positioning plate 307 to adaptively rotate during the process of clamping and positioning the hub. Therefore, the contact area between the outer arc-shaped surface of the positioning plate 307 and the inner circle of the hub increases, increasing the force-bearing area during positioning clamping and avoiding the problem of damage to the hub by the positioning plate 307 during clamping and positioning.

[0030] Refer to Figure 3, two symmetrically arranged shaft grooves 31 are formed on the outer arc surface of the positioning plate 307. A rotating shaft is rotatably arranged between the front and rear end faces of the inner wall of the shaft groove 31. A rubber roller 310 made of rubber is fixedly sleeved on the rotating shaft, and the rubber roller 310 contacts the arc surface of the inner ring of the hub.

[0031] During operation, when the positioning plate 307 positions and clamps the hub, the provided rubber roller 310 is in close contact with the arc surface of the inner ring of the hub, so that the hub can rotate within a certain angle after positioning and clamping, which is convenient for subsequent alignment of the hub with the drive shaft 2 and subsequent installation with bolts. In addition, after the rubber roller 310 contacts the hub, the contact between other devices and the hub is reduced, thus avoiding the problem of damage to the hub by the devices.

[0032] Refer to Figure 2 , Figure 4 , Figure 6 and Figure 7 , a placement groove is formed on the front end face of the mounting plate 1. An operating shaft 32 is arranged in the placement groove. The rear end face of the operating shaft 32 passes through the mounting plate 1 and is fixedly provided with a cylinder plate. A telescopic cylinder 320 with a telescopic end fixedly connected to the cylinder plate is arranged between the cylinder plate and the mounting plate 1. A rotating gear 321 is rotatably arranged on the front end face of the mounting plate 1 through a gear shaft. A gear groove 322 meshing with the rotating gear 321 is formed on the circumferential surface of the operating shaft 32. Two symmetrically arranged front shift grooves 323 are formed on the front end face of the operating shaft 32 from front to back. Electric sliders are slidably arranged in the front shift grooves 323. A front shift shaft 324 is fixedly arranged on the end face of the electric slider away from the operating shaft 32, and the front shift shaft 324 is in mutual cooperation with the mounting hole and the mating hole. A synchronous ring 325 is fixedly arranged on the rear end faces of the two front shift shafts 324. A fitting plate 326 is fixedly sleeved on the middle position of the front shift shaft 324.

[0033] During operation, when the hub moves to the specified position and aligns with the drive shaft 2, the provided telescopic cylinder 320 works to retract its telescopic end, so that the operating shaft 32 moves forward to the rear of the center position of the hub. At the same time, the electric sliders in the front shift grooves 323 work, so that the front shift shafts 324 move forward and are inserted into the mounting holes on the hub and the drive shaft 2, so that the hub and the drive shaft 2 are moved to the installation position. At the same time, an existing external motor works to drive the rotation of the rotating gear 321 through the gear shaft. The rotation of the operating shaft 32 is synchronized through the meshing between the rotating gear 321 and the gear groove 322, so as to adjust the position of the mounting hole, so that the mounting hole rotates with the hub by a certain angle to the position directly above the axis of the hub, which is convenient for the subsequent assembly mechanism 4 to assemble the hub with bolts. In addition, after the fitting plate 326 moves forward with the front shift shaft 324 and is in close contact with the hub, the telescopic cylinder 320 stops working.

[0034] Refer toFigure 4 and Figure 7 At the front end face of the synchronization ring 325, two mating grooves that are centrosymmetric about the axis center of the operating shaft 32 are provided. A connecting column 33 is slidably arranged in the mating groove. The rear end faces of the two connecting columns 33 are fixedly connected together with an auxiliary ring 330. At the rear end face of the synchronization ring 325, two symmetrically arranged auxiliary cylinders 331 are fixedly provided. The telescopic end of the auxiliary cylinder 331 is fixedly connected to the front end face of the auxiliary ring 330. The front end face of the connecting column 33 passes through the mating groove and then is fixedly provided with an auxiliary shaft 332, and the auxiliary shaft 332 has the same shaft diameter as the forward movement shaft 324.

[0035] After the forward movement shaft 324 moves forward into the mounting hole of the hub and the assembly hook 4 installs the mounting bolt in the mounting hole at the highest position, the positioning plate 307 is moved out of the inner ring of the hub through the cooperation between the T-shaped block 300 and the corresponding rearward movement groove. Then the auxiliary cylinder 331 works to retract its telescopic end, so that the auxiliary shaft 332 is moved into the mounting hole without a bolt installed through the auxiliary ring 330. At the same time, the electric slider in the forward movement groove 323 moves rearward to move the forward movement shaft 324 out of the corresponding mounting hole. Then the external motor works to drive the rotating gear 321 to rotate through the gear shaft, so that the operating shaft 32 drives the hub and the drive shaft 2 to rotate through the auxiliary shaft 332. Therefore, the mounting hole without a bolt installed is moved to directly above the axis of the hub, and subsequent assembly operations are carried out. Thus, through the mutual staggered cooperation of the auxiliary shaft 332 and the forward movement shaft 324 with the hub, it is convenient for the assembly mechanism 4 to carry out assembly operations on different mounting holes.

[0036] Refer to Figure 7 and Figure 8 At the front end face of the operating shaft 32, a fitting circular plate 34 made of rubber is fixedly provided, and the opposite faces of the two fitting plates 326 and the hub are both made of rubber.

[0037] During operation, the telescopic cylinder 320 works to retract its telescopic end, so that the operating shaft 32 moves forward to be closely attached to the rear end face of the hub and has a forward acting force on the hub, which is convenient for subsequent alignment and assembly operations. The provided fitting circular plate 34 contacts the hub. The rubber materials of the fitting circular plate 34 and the fitting plate 326 avoid the problem that the operating shaft 32 directly contacts the hub and causes scratches or damage to the hub.

[0038] Refer to Figure 2 , Figure 5 , Figure 6 and Figure 8, the assembly mechanism 4 includes a downward movement groove 40. An upward-downward downward movement groove 40 is formed on the upper end surface of the mounting plate 1. An electric slider is arranged in the downward movement groove 40. A transverse plate is fixedly arranged on the front end surface of the electric slider. A transverse groove 400 is formed on the upper end surface of the transverse plate. An electric slide plate is arranged in the transverse groove 400. A blanking plate 401 is fixedly arranged on the front end surface of the electric slide plate. A T-shaped groove 402 that penetrates the blanking plate 401 from top to bottom is formed on the upper end surface of the blanking plate 401. Bolts for fixing the hub on the drive shaft 2 are placed in the T-shaped groove 402. An installation cylinder 403 is fixedly arranged on the rear end surface of the blanking plate 401. A mating circular plate 404 is fixedly arranged on the telescopic end surface of the installation cylinder 403. An assembly shaft 405 is rotatably arranged on the lower end surface of the mating circular plate 404. An assembly part 406 that cooperates with the bolt is fixedly arranged on the front end surface of the assembly shaft 405.

[0039] During operation, when the hub is positioned and clamped and the unfitted mounting holes on the hub are located at the designated positions, first, through the mutual cooperation of the electric slider in the downward movement groove 40 and the electric slider in the transverse plate, the blanking plate 401 is moved to the designated position. Then, the bolts placed in the T-shaped groove 402 freely fall under the action of gravity. At the same time, the set installation cylinder 403 works, and its telescopic end causes the mating circular plate 404 to drive the assembly shaft 405 to move forward synchronously. And the assembly shaft 405 pushes the corresponding bolts into the corresponding mounting holes. And the existing external motor works to drive the assembly shaft 405 to rotate. Thus, the assembly shaft 405 assembles the hub on the drive shaft 2 through the mutual cooperation between the assembly part 406 and the bolt. After that, the positioning mechanism 3 rotates the hub by a certain angle and repeats the above operation. Finally, bolts are installed in each mounting hole.

[0040] Refer to Figure 5 , a limiting groove from right to left is formed on the right end surface of the blanking plate 401. An L-shaped limiting plate 41 is slidably arranged in the limiting groove, and the horizontal part of the limiting plate 41 slides in the limiting groove. Two horizontally symmetric horizontal plates are fixedly arranged on the right end surface of the blanking plate 401. A cam 410 that is in close contact with the vertical part of the limiting plate 41 is rotatably arranged between the two horizontal plates through a rotating shaft. An auxiliary spring 411 is arranged between the vertical part of the limiting plate 41 and the blanking plate 401.

[0041] During operation, the existing external motor works to drive the cam 410 to rotate through the rotating shaft. Thus, the rotation of the cam 410 enables the limiting plate 41 to move back and forth in the left-right direction. At this time, the auxiliary spring 411 deforms. And the number of bolts falling can be controlled by the blocking of the limiting plate 41 in the T-shaped groove 402 to avoid a large number of bolts falling simultaneously. And the elastic force generated by the deformation of the set auxiliary spring 411 enables the vertical part of the limiting plate 41 to be in close contact with the cam 410.

[0042] Refer to Figure 8 , both end faces of the blanking plate 401 are hinged with two symmetrically arranged baffles 42 on the left and right by a hinge shaft. L-shaped plates 420 are fixedly arranged on both the left and right end faces of the blanking plate 401. A resistance spring 421 is jointly arranged between the vertical part of the L-shaped plate 420 and the corresponding baffle 42. The opposite surface of the baffle 42 and the assembly 406 is an arc-shaped structure. Elastic strips 422 made of rubber are arranged at the middle positions of the opposite surfaces of the two baffles 42.

[0043] During the assembly operation, after the bolt falls into the T-shaped groove 402, the arranged baffle 42 has a resistance effect on the falling bolt under the elastic force of the corresponding resistance spring 421, so that the two bolts cooperate with each other to hold the bolt up. At this time, the front end of the bolt is placed on the strip 422. Then the assembly shaft 405 pushes the bolt into the installation hole and the corresponding mating hole. The two arranged strips 422 cooperate with each other to lift the bolt, so as to cooperate with the two baffles 42 to facilitate the horizontal placement of the bolt, which is convenient for the subsequent pushing of the bolt by the assembly shaft 405 and subsequent assembly.

[0044] In addition, the present invention also provides a waterproof hub positioning and assembly process, including the following steps: S1. Clamp the hub: First, manually move the hub to the designated position and make the positioning plate 307 located inside the inner ring of the hub. At the same time, an external existing motor works to drive the driving gear 305 to rotate through the gear shaft. Through the cooperation between the driving gear 305 and the rack, the two racks move away from each other. Therefore, the outer arc surface of the positioning plate 307 is closely attached to the inner arc surface of the hub at this time. The hub is clamped and positioned through the cooperation between the four positioning plates 307. Then the electric slider in the vertical movement groove 302 works to lift the hub to the designated height through the placement plate 303 and the transition plate 306 and move the hub through the transverse movement plate 30 in the transverse movement groove, so as to move the hub to the exact rear of the driving shaft 2 through the positioning mechanism 3.

[0045] S2. Position the hub: After the hub moves to the designated position and aligns with the driving shaft 2, the arranged telescopic cylinder 320 works to retract its telescopic end. Therefore, the operating shaft 32 moves forward to the rear of the center position of the hub. At the same time, the electric slider in the forward movement groove 323 works to make the forward movement shaft 324 move forward and insert into the installation holes on the hub and the driving shaft 2. An external existing motor works to drive the rotating gear 321 to rotate through the gear shaft. Through the meshing between the rotating gear 321 and the gear groove 322, the operating shaft 32 rotates synchronously, so as to adjust the position of the installation hole, so that the installation hole rotates with the hub by a certain angle to the position directly above the hub axis.

[0046] S3. Assembly operation: Through the mutual cooperation of the electric slider in the downward shifting groove 40 and the electric slider in the horizontal plate, the blanking plate 401 is moved to the designated position. Then, the bolts placed in the T-shaped groove 402 freely fall under the action of gravity. At the same time, the installed installation cylinder 403 works, and its telescopic end makes the matching circular plate 404 drive the assembly shaft 405 to move forward synchronously. And the assembly shaft 405 pushes the corresponding bolts into the corresponding installation holes and matching holes. In addition, the existing external motor works to drive the assembly shaft 405 to rotate. Thus, the assembly shaft 405 assembles the hub on the drive shaft 2 through the mutual cooperation between the assembly parts 406 and the bolts.

[0047] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
