Description

Technical Field

[0001] This invention relates to the field of wheel hub manufacturing technology, specifically a welding process for producing forward and reverse rim wheel hubs. Background Technology

[0002] The wheel hub is a crucial component connecting the wheel and the vehicle's suspension system, and it needs to withstand various loads and rotational torques during vehicle operation. The wheel rim refers to the outer circumference of the wheel hub, which is the part that directly contacts the tire. Its main function is to provide support and secure the tire.

[0003] Welding rims to hubs is a common manufacturing process. However, since a hub typically has only one rim, existing welding methods are generally suitable for welding hubs with only a single rim. When welding hubs with two rims, manual rotation and adjustment of the hub and repositioning of the welding equipment are often required, reducing the overall efficiency of the welding process. Therefore, improvements are necessary. Summary of the Invention

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-5 In this embodiment of the invention, a welding process for producing forward and reverse rim hubs includes the following steps:

[0031] Step 1: Place the wheel hub body 4 on the processing table 1, and use the conveying mechanism to send the wheel hub body 4 into the forward welding station;

[0032] Step 2: The wheel hub body 4 is limited by the limiting unit, and the loading mechanism feeds out the wheel rims 5 one by one and fits them into the wheel hub body 4;

[0033] Step 3: The hub body 4 and the rim 5 are welded together by the welding mechanism. The hub body 4 is driven to rotate by the drive assembly to complete the welding of the rim 5 and the hub body 4 in the forward position.

[0034] Step 4: The welded wheel hub is lifted out by the lifting assembly and sent to the reverse welding station by the conveying mechanism. Steps 2 and 3 are repeated to complete the welding of the wheel rim 5 and the wheel hub body 4 in the reverse position.

[0035] Step 5: The welded wheel hub is lifted out by the lifting assembly and sent out by the conveying mechanism, completing the welding process of the five wheel hubs with forward and reverse rims.

[0036] This embodiment also provides a welding processing device for rim and hub in both directions using a welding processing method, including a processing table 1, a conveying mechanism on the top of the processing table 1, and a forward welding station and a reverse welding station arranged sequentially on the conveying path of the conveying mechanism, wherein the welding of the rim 5 and hub body 4 in the forward and reverse positions is completed by the forward welding station and the reverse welding station respectively.

[0037] Both the forward and reverse welding stations are equipped with a processing groove 3. One side of each processing groove 3 extends outward and penetrates one side of the processing table 1 to form an opening. The openings of the two processing grooves 3 face opposite directions. A feeding mechanism is installed on the processing table 1 near the openings of the two processing grooves 3. A welding mechanism is installed on the top of the processing table 1 away from the openings of the processing grooves 3. The openings of the two processing grooves 3 face opposite directions, and the welding mechanism and the feeding mechanism are also arranged in opposite directions. This allows the wheel hub to be welded to both rims 5 without having to be rotated during the conveying process.

[0038] The conveying mechanism includes a conveyor frame 26, and a conveyor belt 27 is rotatably mounted on the inner wall of the conveyor frame 26. By setting the conveyor belt 27 in conjunction with the conveyor frame 26, the vertical guiding and conveying of the wheel hub is realized, thereby facilitating the welding processing of the forward and reverse rims 5 on both sides of the wheel hub on the conveying path. In order to improve the positional stability of the wheel hub during the conveying process, several blocks are fixedly connected to the surface of the conveyor belt 27.

[0039] A limiting unit is provided inside the processing groove 3. The limiting unit includes a support frame 8 fixedly connected to the bottom of the inner wall of the processing groove 3. A support roller 9 is rotatably connected to the inner wall of the support frame 8. A movable groove is opened at one end of the inner wall of the processing groove 3. An adjusting push rod 12 is fixedly installed on the inner wall of the movable groove. A pressing rod 13 is rotatably connected to the output end of the adjusting push rod 12. An inclined surface is provided at the end of the pressing rod 13. The hub body 4 falling into the processing groove 3 is supported from the bottom by the support roller 9. The pressing rod 13 presses the inner wall of the hub body 4. The hub body 4 is limited without affecting the rotation of the hub body 4, thus ensuring the stability of the hub position during the welding process.

[0040] Both sides of the inner wall of the limiting groove are provided with driving components. The driving components include a mounting frame. The inner wall of the mounting frame is rotatably connected to a driving roller 7. The outer wall of the driving roller 7 is fixedly connected to several contact pads. By setting the rotation of the driving roller 7, the contact pads and the outer wall of the wheel hub will drive the wheel hub body 4 to rotate as a whole, thereby realizing the adjustment of the wheel hub posture.

[0041] The welding mechanism includes a welding frame 2, a shifting guide rail fixedly installed on the top of the welding frame 2, a welding seat slidably installed on the inner wall of the shifting guide rail, and a welding head 6 fixedly installed on the bottom of the welding seat; auxiliary positioning components are provided on both sides of the processing groove 3 port, and the pressing positioning components include a servo motor, with a pressing plate 28 fixedly connected to the output end of the servo motor; during the welding process, the welding mechanism drives the welding head 6 to move through the shifting guide rail, and drives the rim 5 body and rim 5 to rotate through the driving component, so that the welding head 6 can stably weld the rim 5 body and rim 5 at various points.

[0042] The tops of both sides of the inner wall of the limiting groove are inclined. The lifting assembly includes a lifting push rod 10, and a lifting support plate is fixedly connected to the top of the lifting push rod 10. A transfer roller 11 is rotatably connected to the top of the lifting support plate. After welding is completed, the lifting assembly lifts the wheel hub out of the processing groove 3 and, together with the transfer roller 11, sends the wheel hub body 4 into the conveying mechanism.

[0043] The feeding mechanism includes a base 14, a feeding push tube 15 fixedly connected to the top of the base 14, a feeding guide rail 16 fixedly installed on the inner wall of the feeding push tube 15, a connecting frame slidably installed on the inner wall of the feeding guide rail 16, a feeding push rod 17 fixedly connected to the middle of the connecting frame, a push turntable 18 rotatably connected to the output end of the feeding push rod 17, and several positioning suction cups 19 fixedly connected to the edge of the push turntable 18; the positioning suction cups 19 adsorb the rims 5 one by one and push the rims 5 out to fit against the hub body 4. After fitting, the pressing positioning component presses the rims 5 to ensure stable contact between the rims 5 and the hub body 4 and to ensure stable welding position;

[0044] A flipping motor is embedded in the middle of the base 14. A flipping plate 20 is fixedly connected to the output end of the flipping motor. A gap is provided between the flipping plate 20 and the push turntable 18. A feed inlet 25 is opened at the top of the feeding push pipe 15. The top of the feed inlet 25 is correspondingly set to the top of the gap. During the adsorption and positioning of the rim 5 by the positioning suction cup 19, the flipping plate 20 is driven by the flipping motor to temporarily support the rim 5 and ensure that the positioning suction cup 19 adsorbs stably.

[0045] A receiving cover plate 22 is fixedly connected to the top of the feeding push pipe 15. A push cylinder 21 is fixedly installed on one side of the receiving cover plate 22. A placement box 23 is fixedly connected to the output end of the push cylinder 21. Several placement slots 24 are opened in the middle of the placement box 23. Wheel rims 5 are slidably placed in the placement slots 24. The feeding mechanism collects several wheel rims 5 through the several placement slots 24 set on the placement box 23, and the push cylinder 21 pushes the placement box 23 so that the several placement slots 24 pass through the feed port 25 in sequence, thereby realizing the sequential delivery of wheel rims 5.

[0046] In use, the hub body 4 is placed vertically on the conveyor belt 27 by manual operation or external feeding equipment, with the bottom of the hub body 4 in contact with the stop block. The rotation of the conveyor belt 27 feeds the hub into the processing groove 3 of the forward welding station. The hub is supported by the supporting roller 9 and the driving rollers 7 on both sides. The adjusting push rod 12 drives the pressing rod 13 to move, so that the pressing rod 13 extends and contacts the inner wall of the hub body 4, realizing downward pressing and limiting of the hub body 5 from the inner wall of the hub body 5. This, together with the supporting roller 9 and the driving roller 7, achieves the limiting of the hub.

[0047] The push cylinder 21 is activated, aligning the placement slot 24 with the feed inlet 25. The wheel rim 5 in the placement slot 24 falls into the gap of the feeding push tube 15 under gravity. The feeding guide rail 16 drives the feeding push rod 17 to move, which in turn drives the push turntable 18 to move, causing the positioning suction cups 19 at each position to contact the wheel rim 5, achieving adsorption and fixation. Then, the tilting motor drives the tilting plate 20 to rotate and move downwards, avoiding contact between the wheel rim 5 and the push turntable 18. The feeding guide rail 16 drives the push turntable 18 to move until the wheel rim 5 and the wheel hub are in tight contact. After contact, a servo motor drives the pressing... The plate 28 rotates, and the pressing plate 28 presses the rim 5 to ensure stable contact between the rim 5 and the hub body 4, ensuring a stable welding position. The shifting guide rail drives the welding head 6 to move and weld the hub and rim 5. At the same time, the drive roller 7 starts to drive the rim body and rim 5 to rotate. The welding head 6 can stably weld the rim body and rim 5 at various points. After welding is completed, the lifting assembly lifts the hub out of the processing slot 3, and the transfer roller 11 sends the hub into the conveying mechanism. The conveying mechanism sends the hub with the rim 5 welded in the forward position to the reverse welding station to complete the welding in the reverse position.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
