Description

Technical Field

[0001] This invention relates to the field of repair tooling technology, and more specifically, to a tooling for repairing automotive parts. Background Technology

[0002] Tooling, also known as process equipment, refers to the general term for all tools used in the manufacturing process. This includes cutting tools, fixtures, and workstation equipment. Tooling is its common abbreviation. In the automotive manufacturing industry, car wheel hubs form the skeleton of car tires, and the main structural shape of a car wheel hub is circular. During use, car wheel hubs are prone to deformation under pressure, impact, or scratches. Wheel hubs with minor deformation require repair to ensure the safety of the vehicle during subsequent driving.

[0003] Before maintenance, wheel hubs are typically secured using fixtures. However, during repair work, these fixtures often obscure parts of the wheel hub, hindering the worker's overall observation and inspection, making comprehensive maintenance difficult. To ensure effective inspection of all parts of the wheel hub, operators usually need to repeatedly disassemble and reassemble the hub to adjust the clamping position. This repeated clamping operation is not only time-consuming but also increases the physical burden on the workers. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a tooling for repairing automotive parts.

[0005] The technical solution is as follows:

[0006] A tooling for repairing automotive parts includes a workbench with a clamping assembly. The clamping assembly includes a support platform located at the center of the top of the workbench, a slider slidably mounted inside the support platform, and multiple guide grooves extending towards the center of the top of the workbench on the surface of the support platform. Clamping arms are slidably mounted in the guide grooves. A mounting ring is slidably mounted on the bottom wall of the slider and the outer wall of the support platform. A connecting rod is hinged between the mounting ring and the clamping arms. A contact element that passes through the support platform and is located on the outside for placing wheel hub parts is rotatably connected to the top of the slider.

[0007] The top of the contact element extends upward to form a positioning rod through which the center hole of the wheel hub part passes. The outer wall of the positioning rod has multiple third openings. The clamping assembly includes a pressing block that is slidably disposed inside the third opening and engages with the inner wall of the center hole of the wheel hub part.

[0008] A downward-extending sliding cavity is provided on the top wall of the positioning rod, and a top block is slidably installed in the sliding cavity. An adjustment component is rotatably installed on the top of the contact element. The adjustment component is used to drive the top block and the mounting ring to move synchronously.

[0009] Furthermore, the support platform has a cavity for sliding installation of the slider, the top wall of the support platform has a spline groove communicating with the cavity, the top wall of the slider has an extension post that passes through the spline groove and connects with the contact element, and the outer wall of the extension post has a spline that mates with the spline groove.

[0010] Furthermore, the clamping assembly also includes multiple guide rods disposed on the outer wall of the support platform. The multiple guide rods are arranged parallel to the guide groove, and the clamping arm has a through hole that mates with the outer wall of the guide rod.

[0011] Furthermore, the bottom wall of the slider has a downwardly extending extension, the bottom of which is fixedly connected to a base plate. A second opening is provided on the outer wall of the extension. A sliding disk is slidably mounted on the inside of the slider, the second opening, and the outer wall of the extension. The outer wall of the support platform has multiple first openings corresponding to the second opening. The outer wall of the sliding disk has a protrusion that passes through the first opening and connects to the mounting ring.

[0012] Furthermore, the inner walls on both sides of the third port are provided with inwardly recessed grooves, and the side walls on both sides of the extrusion block are provided with extension blocks that extend into the grooves. A spring is fixedly connected between the groove and the extension block, and the spring is used to provide elastic force to keep the extrusion block pressed outward.

[0013] Furthermore, the top of the extrusion block away from the positioning rod has a downwardly inclined guide surface, the end of the extrusion block inside the positioning rod has a first inclined surface inclined towards the guide surface, and the top wall of the top block has a second inclined surface that cooperates with the first inclined surface.

[0014] Furthermore, the adjustment assembly includes an adjustment rod rotatably disposed inside the slider and a cover plate detachably disposed on the top of the positioning rod. An upper screw rod for threaded installation of the top block is fixedly connected to the top wall of the adjustment rod, and a rotating component is rotatably mounted on the top of the cover plate. The rotating component is connected to the upper screw rod by bolts.

[0015] Furthermore, a lower screw is fixedly connected to the bottom wall of the adjusting rod for threaded installation of the sliding disc, and the end of the sliding disc away from the adjusting rod is rotatably installed on the top of the base plate.

[0016] Furthermore, a fixing lug is fixedly connected to the top of the rotating part.

[0017] Based on the above, the beneficial effects of the tooling for repairing automotive parts in this invention are as follows:

[0018] By setting up the clamping assembly, when the hub is placed on the contact piece, the downward pressure causes the slider to move downward. The downward movement of the slider causes the clamping arm to move towards the outer wall of the hub part through the connecting rod, thereby adaptively forming a stable and reliable radial constraint on the outer wall of the hub part.

[0019] By combining the clamping and holding components, the wheel hub parts can be quickly and stably clamped when installed at the contact point. Automatic radial alignment is achieved as the wheel hub parts are placed, ensuring that the axis of the wheel hub parts coincides with the work station reference. This provides a precise positioning basis for subsequent repairs and avoids displacement or shaking of the wheel hub parts during the repair process, ensuring repair accuracy and operational safety.

[0020] By adjusting the component settings, when it is necessary to change the clamping position of the outer wall of the wheel hub part, the top block and sliding plate are moved upward synchronously by rotating the adjusting rod. This causes the top block to press outward against multiple extrusion blocks, thereby limiting the inner wall of the center hole of the wheel hub. At the same time, the mounting ring moves upward synchronously, causing the clamping arm at the mounting ring to release its grip on the outer wall of the wheel hub part. This transforms the clamping arm, i.e., the clamping component, from clamping the outer wall of the wheel hub part to clamping the extrusion blocks, i.e., the pressing component, from clamping the inner wall of the center hole of the wheel hub part. At this point, the user can rotate the wheel hub part. This avoids the problem of traditional clamps obstructing part of the wheel hub part during maintenance, which would affect the maintenance work. It also eliminates the need to repeatedly clamp the wheel hub part to change the clamping position. The operation is simple, the conversion time is short, and the repair efficiency is improved. This device is small in size, easy to move, and can be operated without a power source, eliminating the cumbersome steps of traditional bolt locking or pneumatic clamping.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] The embodiments provided by the present invention will be described in detail below:

[0037] like Figures 1 to 9 As shown, a tooling for repairing automotive parts includes a workbench 100, on which a clamping assembly 200 is provided. The clamping assembly 200 includes a support platform 120 located at the top center of the workbench 100. A slider 210 is slidably installed in the moving cavity of the support platform 120. Multiple guide grooves 110 extending towards the top center of the workbench 100 are formed on the surface of the support platform 120. A clamping arm 260 is slidably installed in the guide grooves 110. An mounting ring 280 is slidably installed on the bottom wall of the slider 210 and the outer wall of the support platform 120. A connecting rod 270 is hinged between the mounting ring 280 and the clamping arm 260. A contact member 230, which passes through the support platform 120 and is located on the outside for placing wheel hub parts, is rotatably connected to the top of the slider 210.

[0038] A spring-loaded assembly is installed between the bottom wall of the cavity and the bottom wall of the slider 210. This spring-loaded assembly provides the spring force to keep the slider 210 pressed upwards, ensuring that when no hub parts are placed on the contact member 230, the contact member 230 is positioned away from the support platform 120. Figure 2 The state shown is as follows. Figure 1 For the state after the wheel hub parts are placed, the spring-loaded component can be a spring.

[0039] It should be noted that when the hub is placed on the contact member 230, the downward pressure causes the slider 210 to move downward. The downward movement of the slider 210 drives the clamping arm 260 to move towards the outer wall of the hub part through the connecting rod 270, thereby adaptively forming a stable and reliable radial constraint on the outer wall of the hub part.

[0040] like Figure 3 As shown, the support platform 120 has a cavity for sliding installation of the slider 210. The top wall of the support platform 120 has a spline groove communicating with the cavity. The top wall of the slider 210 has an extension post 220 that passes through the spline groove and connects with the contact member 230. The outer wall of the extension post 220 has a spline that mates with the spline groove.

[0041] It should be noted that the spline groove and spline are designed to ensure that the slider 210 does not rotate when it slides up and down in the cavity, thereby driving all clamping arms 260 to perform radial clamping and loosening precisely and synchronously through the connecting rod 270.

[0042] like Figure 4 As shown, the clamping assembly 200 also includes a plurality of guide rods 250 disposed on the outer wall of the support platform 120. The plurality of guide rods 250 are arranged parallel to the guide groove 110, and the clamping arm 260 has a through hole that mates with the outer wall of the guide rods 250.

[0043] It should be noted that the single guide groove 110 mainly constrains the movement of the clamping arm 260 in the horizontal plane. With the setting of the guide rod 250, a stable two-point guiding structure is formed, which improves the stability of the clamping arm 260 during the clamping process and ensures that all clamping arms 260 can truly move towards the center or move backward synchronously and concentrically, thereby achieving more precise centering and a more uniform distribution of clamping force, and improving the accuracy and reliability of clamping.

[0044] Specifically, during use, the side where the user connects the hub component to the drive shaft, i.e., the side with the depth, is shown in... Figure 1As shown, the wheel hub part is placed on top of the contact member 230. At this time, due to the weight of the wheel hub part, it will press down on the contact member 230. The downward movement of the contact member 230 will drive the slider 210 to move downward. The downward movement of the slider 210 will drive the mounting ring 280 to move downward. The downward movement of the mounting ring 280 will drive one end of the connecting rod 270 hinged to it to move downward. The downward movement of one end of the connecting rod 270 will pull the clamping arm 260 to move along the guide rod 250 and the guide groove 110 towards the axis of the bearing platform 120 until the clamping arm 260 constrains the outer wall of the wheel hub part, achieving preliminary correction and playing an auxiliary clamping role on the outer wall of the wheel hub part.

[0045] like Figures 1 to 5 , Figure 7 and Figure 8 As shown, the top of the contact member 230 extends upward to a positioning rod 240 through which the center hole of the wheel hub part passes. The outer wall of the positioning rod 240 is provided with a plurality of third openings 241. The pressing assembly 300 includes a pressing block 310 that is slidably disposed inside the third opening 241 and cooperates with the inner wall of the center hole of the wheel hub part.

[0046] The center hole of the wheel hub component is the insertion hole that is fitted onto the drive shaft at the center of the wheel hub component. This is existing technology and will not be described in detail here.

[0047] like Figure 8 and Figure 9 As shown, the inner walls on both sides of the third port 241 are provided with inwardly recessed grooves 242, and the side walls on both sides of the extrusion block 310 are provided with extension blocks 311 that extend into the grooves 242. A spring (not shown) is fixedly connected between the grooves 242 and the extension blocks 311. The spring is used to provide elastic force to keep the extrusion block 310 pressed outward.

[0048] It should be noted that when the center hole of the wheel hub part is inserted, the pressing block 310 will automatically compress the spring and retract according to the actual size of the center hole, always maintaining a close fit with the inner wall of the center hole of the wheel hub part.

[0049] Understandably, the combination of the clamping component 300 and the clamping component 200 allows for quick and stable clamping of the wheel hub parts when they are installed at the contact point 230, while also enabling rapid centering. Automatic radial centering is achieved simultaneously with the placement of the wheel hub parts, ensuring that the axis of the wheel hub parts coincides with the work station reference. This provides a precise positioning basis for subsequent repairs and prevents the wheel hub parts from shifting or shaking during the repair process, thus ensuring repair accuracy and operational safety.

[0050] Furthermore, by using the clamping assembly 300 and the holding assembly 200 in combination, the device can be adapted to the outer wall (i.e., outer ring) of different diameter wheel hub parts and the center hole of different diameter wheel hub parts, thereby improving the applicability and practicality of the device.

[0051] like Figure 8 and Figure 9 As shown, a downwardly extending sliding cavity 211 is provided on the top wall of the positioning rod 240. A top block 460 is slidably installed in the sliding cavity 211. The top block 460 moves vertically along the sliding cavity 211. An adjustment component 400 is rotatably installed at the top of the contact member 230. The adjustment component 400 is used to drive the top block 460 and the mounting ring 280 to move synchronously.

[0052] The adjustment assembly 400 includes an adjustment rod 410 rotatably disposed inside the slider 210 and a cover plate 430 detachably disposed on the top of the positioning rod 240. An upper screw 420 for threaded installation of the top block 460 is fixedly connected to the top wall of the adjustment rod 410. A rotating component 440 is rotatably mounted on the top of the cover plate 430. The rotating component 440 is connected to the upper screw 420 by bolts 450.

[0053] It should be noted that the top of the positioning rod 240 is provided with a threaded hole, and the top wall of the cover plate 430 is provided with a round hole corresponding to the threaded hole. A screw threaded into the threaded hole is installed in the round hole to connect the cover plate 430 to the top of the positioning rod 240. The cover plate 430 can be detached from the top of the positioning rod 240 to facilitate the maintenance or replacement of the extrusion block 310.

[0054] The bottom wall of the slider 210 has a downwardly extending extension, and a base plate 212 is fixedly connected to the bottom of the extension. A second opening 213 is provided on the outer wall of the extension. A sliding disk 480 is slidably mounted inside the slider 210, the second opening 213 and the outer wall of the extension. The outer wall of the support platform 120 has a plurality of first openings 130 corresponding to the second opening 213. The outer wall of the sliding disk 480 has a protrusion that passes through the first opening 130 and connects to the mounting ring 280.

[0055] It should be noted that the arrangement of the first port 130, the second port 213 and the protrusion enables the sliding disk 480 and the mounting ring 280 to move stably along the first port 130 and the second port 213, thereby improving the stability of the slider 210 when driving the connecting rod 270.

[0056] A lower screw 470 for threaded installation of a sliding disc 480 is fixedly connected to the bottom wall of the adjusting rod 410. The end of the sliding disc 480 away from the adjusting rod 410 is rotatably installed on the top of the base plate 212.

[0057] It should be noted that by rotating the adjusting rod 410, the sliding plate 480 can be moved vertically along the extension. The movement of the sliding plate 480 can drive the mounting ring 280 connected to the sliding plate 480 to move, thereby allowing for local height adjustment of the mounting ring 280.

[0058] like Figure 8 and Figure 9 As shown, the top of the extrusion block 310 away from the positioning rod 240 has a downwardly inclined guide surface 313, and the end of the extrusion block 310 inside the positioning rod 240 has a first inclined surface 312 inclined towards the guide surface 313. The top wall of the top block 460 has a second inclined surface 461 that cooperates with the first inclined surface 312.

[0059] It should be noted that by setting the guide surface 313, when the inner wall of the center hole of the wheel hub part comes into contact with the extrusion block 310, the extrusion block 310 can be extruded inward along the guide surface 313, so that the wheel hub part can be better installed at the positioning rod 240.

[0060] It should be noted that the cooperation between the first inclined surface 312 and the second inclined surface 461 of the top wall of the top block 460 allows the top block 460 to better contact the extrusion block 310 while extruding the extrusion block 310 outward when the top block 460 moves upward, so that it slowly contacts the inner wall of the center hole of the wheel hub part and forms a limit on the inner wall of the center hole of the wheel hub part.

[0061] Specifically, when the adjusting rod 410 rotates, it drives the top block 460 to move vertically upward along the sliding cavity 211, while simultaneously driving the sliding disk 480 to move upward. The upward movement of the top block 460 causes the second inclined surface 461 of the top block 460 to cooperate with the first inclined surface 312 of the pressing block 310, converting the vertical thrust into the radial expansion force of the pressing block 310, thereby rigidly locking the inner wall of the center hole of the wheel hub part from the inside. At the same time, the upward movement of the sliding disk 480 drives the mounting ring 280 to move upward, thereby releasing the clamping arm 260 from the clamping limit on the outer wall of the wheel hub part, so that the clamping arm 260 can be adjusted to clamp the outer wall of the wheel hub part.

[0062] like Figures 1 to 7 and Figure 9 As shown, a fixed lug 441 is fixedly connected to the top of the rotating component 440. The fixed lug 441 is used for inserting a steel pipe to drive the rotation of the adjusting rod 410 connected to the rotating component 440.

[0063] It should be noted that the user can drive the adjusting rod 410 to rotate by inserting an external steel pipe into the fixed ear 441, which is simple and quick to operate.

[0064] Specifically, during use, the user aligns the center hole of the hub component with the positioning rod 240, installs the hub component on the contact member 230, and presses the pressing block 310 against the inner wall of the center hole of the hub component, so that the hub component is automatically radially centered. At the same time, due to the weight of the hub component, it will press down on the contact member 230. The contact member 230 moves downward, causing the slider 210 to move downward. The slider 210 moves downward, causing the mounting ring 280 to move downward. The mounting ring 280 moves downward, causing one end of the connecting rod 270 hinged to it to move downward. The one end of the connecting rod 270 moves downward, pulling the clamping arm 260 along the guide rod 250 and the guide groove 110 toward the axis of the bearing platform 120 until the clamping arm 260 clamps the outer wall of the hub component.

[0065] When the clamping position of the outer wall of the wheel hub part needs to be changed, the top block 460 and the sliding plate 480 are driven to move upward synchronously by rotating the adjusting rod 410. This causes the top block 460 to press outward against the multiple pressing blocks 310, thereby limiting the inner wall of the center hole of the wheel hub. At the same time, the mounting ring 280 moves upward synchronously, driving the connecting rod 270 to release the clamping arm 260 at the mounting ring 280 from clamping the outer wall of the wheel hub part. This removes the clamping arm 260, i.e., the clamping assembly 200, from clamping the outer wall of the wheel hub part. The clamping block 310, also known as the clamping assembly 300, clamps the inner wall of the center hole of the wheel hub. At this time, the user can rotate the wheel hub parts. This avoids the problem that traditional clamps would block part of the wheel hub parts during maintenance, which would affect the maintenance work. There is no need to repeatedly clamp the wheel hub parts to change the clamping position. The operation is simple, the conversion time is short, and the repair efficiency is improved. This device is small in size and easy to move. It can be operated without a power source, eliminating the cumbersome steps of traditional bolt locking or pneumatic clamping.

[0066] Once the adjustment is complete, the adjustment lever 410 can be rotated in the opposite direction to reset it. The clamping arm 260, i.e. the clamping assembly 200, will then clamp and limit the outer wall of the wheel hub part again through the weight interface of the wheel hub part.

[0067] The above are merely preferred embodiments of the invention. The scope of protection of the invention is not limited to the above embodiments. All technical solutions falling within the inventive concept are within the scope of protection of the invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the inventive principle should also be considered within the scope of protection of this template.
