[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] like Figure 1As shown, and in combination Figures 2-12 As shown, the automated welding fixture for wheel covers of the present invention includes a support frame 01, a bracket 03 above the support frame 01, a driving member 13 and a first positioning pin 14 on the support frame 01, the driving member 13 being able to drive the first positioning pin 14 to slide vertically along the support frame 01, the bracket 03 having a first positioning hole 29 for cooperating with the first positioning pin 14, a first support member for supporting an inner cover 06, a second positioning pin 32 for cooperating with a second positioning hole on the inner cover 06, and a first clamping member for clamping the inner cover 06, the bracket 03 also having a second support member for supporting an outer cover 05, a third positioning pin 33 for cooperating with a third positioning hole on the outer cover 05, and a second clamping member for clamping the outer cover 05.

[0020] like Figure 2 , 3 As shown in Figures 4 and 5, the automated welding fixture for wheel covers of the present invention includes a support frame 01 comprising a support plate 10 and legs 11. The support plate 10 is arranged horizontally, and the legs 11 are fixedly mounted on the lower side of the support plate 10. The driving component 13 includes a first cylinder 16 and a first bearing plate 19. The first bearing plate 19 is fixedly mounted on the lower side of the support plate 10. The first positioning pin 14 is slidably mounted vertically on the first bearing plate 19. The cylinder body of the first cylinder 16 is fixedly mounted on the first bearing plate 19. The piston rod of the first cylinder 16 is connected to the first positioning pin 14. When the piston rod of the first cylinder 16 extends or retracts, it can drive the first positioning pin 14 to slide vertically along the first bearing plate 19. The support plate 10 is provided with through holes 15 corresponding to the first positioning pin 14.

[0021] The present invention relates to an automated welding fixture for wheel covers, wherein the first support plate 19 includes a vertical support plate 18 and a horizontal support plate 17. The upper end of the vertical support plate 18 is fixedly mounted on the lower side of the support plate 10. A vertically arranged slide rail 21 is fixedly mounted on the vertical support plate 18, and a slider 22 is slidably connected to the slide rail 21. The first positioning pin 14 is fixedly mounted on the second support plate 20, and the second support plate 20 is fixedly mounted on the slider 22. The horizontal support plate 17 is fixedly mounted on the lower end of the vertical support plate 18. The cylinder body of the first cylinder 16 is fixedly mounted on the horizontal support plate 17, and the piston rod of the first cylinder 16 is arranged upward and connected to the second support plate 20.

[0022] The first positioning pin 14 is fixed to the second bearing plate 20 by the L-shaped rod 23. The piston rod of the first cylinder 16 is connected to the second bearing plate 20 by the T-shaped rod 24. That is, the T-shaped rod 24 is fixed on the second bearing plate 20. The piston rod of the first cylinder 16 is hinged to the T-shaped rod 24, and the hinge axis between the two is arranged in the horizontal direction.

[0023] The first positioning pin 14 is fixed to the second bearing plate 20 by the L-shaped rod 23. The second bearing plate 20 is fixed to the slider 22. The slider 22 is slidably connected to the slide rail 21. The slide rail 21 is fixed to the vertical bearing plate 18. Therefore, the first positioning pin 14 is slidably disposed on the vertical bearing plate 18 by the L-shaped rod 23, the second bearing plate 20, the slider 22 and the slide rail 21. It can be considered that the first positioning pin 14 is slidably disposed on the first bearing plate 19 along the vertical direction.

[0024] The first positioning pin 14 is fixed to the second support plate 20 via the L-shaped rod 23. The piston rod of the first cylinder 16 is connected to the second support plate 20 via the T-shaped rod 24. Therefore, it can be considered that the piston rod of the first cylinder 16 is connected to the first positioning pin 14. When the piston rod of the first cylinder 16 extends or retracts, the piston rod drives the second support plate 20 to slide vertically along the vertical support plate 18 via the slider 22 and the slide rail 21 through the T-shaped rod 24. Since the first positioning pin 14 is fixed to the second support plate 20 via the L-shaped rod 23, the first positioning pin 14 slides vertically along with the second support plate 20. That is to say, the piston rod of the first cylinder 16 can drive the first positioning pin 14 to slide vertically along the first support plate 19. Since the first support plate 19 is fixed to the support frame 01, it can be considered that the driving component 13 can drive the first positioning pin 14 to slide vertically along the support frame 01.

[0025] Since the support plate 10 has a through hole 15 corresponding to the first positioning pin 14, when the first positioning pin 14 slides upward, it can pass through the through hole 15 to reach the top of the support plate 10. Then, when installing the bracket 03, the first positioning hole 29 on the bracket 03 can be inserted into the first positioning pin 14.

[0026] In this embodiment, there are two first positioning pins 14, and the support plate 10 has two corresponding through holes 15. The bracket 03 also has two corresponding first positioning holes 29. After the two first positioning pins 14 pass through their respective through holes 15 and reach above the support plate 10, the bracket 03 can be installed. The two first positioning holes 29 on the bracket 03 are then inserted into their respective first positioning pins 14, serving as guides and positioning devices, allowing the bracket 03 to be precisely installed at the corresponding position on the support frame 01.

[0027] Multiple support legs 11 are provided, and the specific number can be determined according to the actual situation. Reinforcing rods 12 are connected between the multiple support legs 11 to enhance the structural strength of the entire support frame 01.

[0028] like Figures 6-10As shown, the automated welding fixture for wheel covers of the present invention includes a bracket 03 comprising a bracket frame 02. A lower support plate 09 is fixedly provided at the bottom of the bracket frame 02. The lower support plate 09 is detachably and fixedly connected to the upper side of the support plate 10. The lower support plate 09 is provided with a first positioning hole 29 corresponding to the through hole 15. An upper support plate 08 is fixedly provided at the top of the bracket frame 02. The upper support plate 08 is provided with a first support member, a second support member, a second positioning pin 32, a third positioning pin 33, a first clamping member, and a second clamping member.

[0029] The lower support plate 09 is provided in four pieces, and the four lower support plates 09 are arranged at intervals at the bottom of the bracket frame 02. The two lower support plates 09 located in the middle are provided with first positioning holes 29.

[0030] In actual use, the bracket 03 has several different types, and each bracket 03 corresponds to a different model of wheel cover welded on. When installing the first bracket 03 onto the support frame 01, the first positioning pin 14 is first driven upward by the drive component 13 to slide above the support plate 10. Then, the first positioning hole 29 on the first bracket 03 is inserted into the first positioning pin 14 until the first bracket 03 is placed on the support plate 10. Then, the lower support plate 09 and the support plate 10 are fixedly connected by bolts, that is, the first bracket 03 is set on the support frame 01. When it is necessary to replace the second bracket 03, the bolts are removed, the first bracket 03 is removed from the support frame 01, and then the first positioning hole 29 on the second bracket 03 is inserted into the first positioning pin 14 until the second bracket 03 is placed on the support plate 10. Then, the lower support plate 09 and the support plate 10 are fixedly connected by bolts, that is, the second bracket 03 is set on the support frame 01. It should be noted that, in addition to being detachably fixed to the support plate 10 via bolts, the lower support plate 09 can also be detachably fixed via screws or other fasteners.

[0031] like Figure 12 As shown, and in combination Figures 6-11 As shown, the automated welding fixture for wheel covers of the present invention includes a first support member comprising multiple vertically arranged first support rods 07, the lower ends of the multiple first support rods 07 being fixedly mounted on an upper support plate 08, and the upper ends of the multiple first support rods 07 being used to abut against the inner sidewall of the inner cover body 06.

[0032] The present invention relates to an automated welding fixture for wheel covers, wherein the first clamping component includes a second cylinder 34, a first upper pressure rod 35, and a first lower push rod 28. The first lower push rod 28 is arranged vertically, and its lower end is fixedly mounted on an upper support plate 08. The upper end of the first lower support plate is used to abut against the inner sidewall of the inner cover body 06. The cylinder body of the second cylinder 34 is fixedly mounted on the upper support plate 08. The piston rod of the second cylinder 34 is arranged upward and fixedly connected to one end of the first upper pressure rod 35. The other end of the first upper pressure rod 35 extends above the first lower push rod 28 and is used to abut against the outer sidewall of the inner cover body 06.

[0033] After the upper sides of the inner cover 06 and the outer cover 05 are welded together, a wheel cover is formed. After the wheel cover is installed on the frame, the inner cover 06 and the outer cover 05 can be considered to be arranged vertically. Therefore, in this invention, when the inner cover 06 and the outer cover 05 are installed on the tooling, the inner sidewalls of the inner cover 06 and the outer sidewalls of the outer cover 05 are both facing down, and the outer sidewalls are both facing up, that is, the inner cover 06 and the outer cover 05 are both arranged horizontally.

[0034] Multiple first support rods 07 are distributed at different positions inside the inner cover 06. The height of each first support rod 07 is adapted to the height of the inner wall of the inner cover 06 so that the inner cover 06 can be arranged horizontally. When the inner cover 06 is placed on the first support rods 07, in order to ensure that each first support rod 07 accurately abuts against the corresponding position of the inner wall of the inner cover 06, a second positioning pin 32 is fixedly installed on the upper support plate 08. A second positioning hole is provided on the inner cover 06 to cooperate with the second positioning pin 32. When the inner cover 06 is placed on the first support rod 07 from top to bottom, the second positioning hole is first inserted into the second positioning pin 32, and then the inner cover 06 is moved downward until it is placed on the first support rod 07.

[0035] To enhance the installation stability of the inner cover 06, a first clamping element is also provided on the upper support plate 08. After the inner cover 06 is placed on the first support rod 07, the inner cover 06 is also placed on the first lower push rod 28, that is, the upper end of the first lower push rod 28 abuts against the inner side wall of the inner cover 06. Then, the piston rod of the second cylinder 34 is retracted, and the first upper pressure rod 35 moves downward until it abuts against the outer side wall of the inner cover 06. Since the upper end of the first upper pressure rod 35 is located above the first lower push rod 28, the first upper pressure rod 35 and the first lower push rod 28 clamp the inner cover 06 at this time, thereby enhancing the installation stability of the inner cover 06 and preventing it from moving.

[0036] When placing the inner cover 06 onto the first support rod 07, the piston rod of the second cylinder 34 needs to extend upwards, and the first upper pressure rod 35 also moves upwards, leaving enough space to install the inner cover 06. After the inner cover 06 is placed on the first support rod 07, the piston rod of the second cylinder 34 is then retracted downwards, and the first upper pressure rod 35 moves downwards until the inner cover 06 is clamped between the first upper pressure rod 35 and the first lower push rod 28.

[0037] The number of the second positioning pins 32 and the second positioning holes can be determined according to the actual situation. The number of the first clamping parts can also be determined according to the actual situation, as long as the position of the inner cover 06 can be fixed.

[0038] The second positioning hole is located on the side of the inner cover 06, and the first clamping member clamps the side of the inner cover 06. To further enhance the installation stability of the inner cover 06, a first vertical baffle 31 is fixedly provided on the upper support plate 08. The first vertical baffle 31 is arranged on the outside of the inner cover 06 and close to the inner cover 06. Under the obstruction of the first vertical baffle 31, the inner cover 06 will not slip off the first support rod 07. Of course, the number of first vertical baffles 31 can also be determined according to the actual situation.

[0039] The present invention provides an automated welding fixture for wheel covers, wherein the second support member includes multiple vertically arranged second support rods 04, the lower ends of the multiple second support rods 04 are fixed on the upper support plate 08, and the upper ends of the multiple second support rods 04 are used to abut against the inner sidewall of the outer cover body 05.

[0040] The present invention relates to an automated welding fixture for wheel covers, wherein the second clamping component includes a third cylinder 37, a second upper pressure rod 38, and a second lower push rod 25. The second lower push rod 25 is arranged vertically, and its lower end is fixedly mounted on an upper support plate 08. The upper end of the second lower push rod 25 is used to abut against the inner sidewall of the outer cover body 05. The cylinder body of the third cylinder 37 is fixedly mounted on the upper support plate 08. The piston rod of the third cylinder 37 is arranged upward and fixedly connected to one end of the second upper pressure rod 38. The other end of the second upper pressure rod 38 extends above the second lower push rod 25 and is used to abut against the outer sidewall of the outer cover body 05.

[0041] The present invention provides an automated welding fixture for wheel covers, wherein a second vertical baffle 30 is fixedly provided on the upper support plate 08, and the second vertical baffle 30 is arranged on the outside of the outer cover body 05 and close to the outer cover body 05.

[0042] The installation method of the outer cover 05 is the same as that of the inner cover 06, and will not be described again. In this embodiment, the inner cover 06 and the outer cover 05 are installed on the upper support plate 08 at intervals in the left and right direction. Since the interval between the two is small, a third clamping member can be set between them. The third clamping member can be regarded as a combination of a first clamping member and a second clamping member. That is, the second cylinder 34 of the first clamping member and the third cylinder 37 of the second clamping member are combined into a total cylinder 27. The first upper pressing rod 35 of the first clamping member and the second upper pressing rod 38 of the second clamping member are combined into a total upper pressing rod 26. When the piston rod of the total cylinder 27 retracts, it drives the total upper pressing rod 26 to move downward until the total upper pressing rod 26 simultaneously abuts against the outer side wall of the inner cover 06 and the outer cover 05. That is, the total upper pressing rod 26 and the first lower push rod 28 clamp the inner cover 06, and at the same time, the total upper pressing rod 26 and the second lower push rod 25 clamp the outer cover 05.

[0043] After the inner cover 06 and outer cover 05 are welded, the clamping parts are released, that is, the cylinder piston rod of the clamping parts extends upward, so the upper pressure rod moves upward and no longer clamps the cover together with the lower push rod. Then the cover is moved from bottom to top, so that the cover is disengaged from the second / third positioning pin, until the cover is removed from the upper support plate 08. Then the other inner cover 06 and outer cover 05 are installed on the upper support plate 08 and welded.

[0044] In this invention, each cylinder is connected to the air circuit system and controlled by air control valves (including air control valve 36). Both the air circuit system and the air control valves are existing technologies, and their specific structures and working principles will not be described in detail here.

[0045] The difference between the automated welding fixture for wheel covers of the present invention and the prior art is that, in use, the first positioning pin 14 is first driven upward by the driving component 13 until the first positioning pin 14 reaches above the support plate 10, and then the bracket 03 is placed on the support frame 01. During this process, the first positioning pin 14 is inserted into the first positioning hole 29. That is, the process of placing the bracket 03 on the support frame 01 is guided by the cooperation of the first positioning pin 14 and the first positioning hole 29, so that the bracket 03 can be accurately placed in the corresponding position of the support frame 01 (the bracket 03 and the support frame 01 are detachably fixedly connected). Next, place the inner cover 06 with its inner wall facing down on the first support member. During this process, the second positioning pin 32 is inserted into the second positioning hole of the inner cover 06. The second positioning pin 32 and the second positioning hole guide the placement of the inner cover 06 onto the first support member, ensuring precise placement. Then, the first clamping member clamps and secures the inner cover 06, completing the fixation of the inner cover 06. Similarly, place the outer cover 05 with its inner wall facing down on the second support member. During this process, the third positioning pin 33 is inserted into the third positioning hole of the outer cover 05. The third positioning pin 33 and the third positioning hole guide the placement of the outer cover 05 onto the second support member, ensuring precise placement. Then, the second clamping member clamps and secures the outer cover 05, completing the fixation of the outer cover 05. Afterward, welding work can be carried out on components such as the wiring brackets on the outer walls of the inner cover 06 and outer cover 05. Therefore, the present invention can conveniently fix the inner cover 06 and the outer cover 05 of the wheel cover, making it convenient for workers to weld components such as cable trays to the outer side walls of the inner cover 06 and the outer cover 05.

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.
