Description

Technical Field

[0001] This utility model relates to a machine tool, and more particularly to a paint protection device for axle assemblies. Background Technology

[0002] In automobile production, after the axle assembly is fully assembled, it needs to be repaired with paint. Currently, there is no systematic tooling for axle assemblies. Simply placing the axle assembly on a flat surface results in insufficient space for painting and an inability to stably support and position it, leading to unsatisfactory paint repair results. This not only affects the quality of the paint repair work but also prolongs the process, reduces efficiency, and may even require repainting, thus increasing costs. Therefore, there is an urgent need for a tooling that can improve the efficiency of axle assembly paint repair. Utility Model Content

[0003] The purpose of this utility model is to provide a paint protection device for axle assemblies to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A paint protection device for axle assembly includes: a tooling frame with slots on both sides along its length, the openings of the two slots facing upwards; and a telescopic component located on one side of the tooling frame along its width, the telescopic component having a support plate that can move up and down and be positioned.

[0006] This technical solution has at least the following beneficial effects: The bridge assembly requiring repainting is placed on a tooling frame, and the wheel hubs within the bridge assembly are positioned in corresponding slots. The slots on both sides of the tooling frame are used to position the wheel hubs, preventing them from moving or rotating during the repainting process, thus ensuring the accuracy and consistency of the repainting. The height of the support plate of the telescopic component is then adjusted so that the support plate abuts against the bridge assembly, adapting to different structural shapes of the bridge assembly and providing auxiliary support. This allows for quick and convenient lifting and positioning of the bridge assembly, reducing preparation time and facilitating comprehensive repainting repair. This improves the efficiency of subsequent repainting repair work, enhances work quality, reduces the need for rework and repairs, and lowers production costs.

[0007] As a further improvement to the above technical solution, the telescopic assembly includes a sleeve and a screw. The sleeve is connected to the tooling frame and extends vertically. The bottom of the screw is threaded into the sleeve, and the support plate is connected to the top of the screw. Through the cooperation of the sleeve and the screw, the height of the support plate can be precisely adjusted according to actual needs. Specifically, rotating the screw moves the support plate up and down to adapt to the height of different corresponding bridge assemblies. The threaded cooperation between the screw and the sleeve achieves self-locking, ensuring the support plate remains stable during paint touch-up and preventing movement or tilting due to external forces. This improves the stability and reliability of the tooling during use, enhancing its adaptability and simplifying the adjustment process, reducing worker operating time and labor intensity, and ensuring the accuracy and quality of the paint touch-up work.

[0008] As a further improvement to the above technical solution, a locking nut is threadedly connected to the outer side of the screw, and the locking nut abuts against the top of the sleeve. The locking nut can firmly abut against the top of the sleeve, preventing the screw from loosening or rotating during up and down movement. This locking mechanism ensures the stability of the support plate during the paint touch-up process, further eliminating work errors caused by loose parts. Workers can fix or release the screw by rotating the locking nut, thereby quickly adjusting the height of the support plate. This not only improves operating efficiency but also enhances the stability of the bridge assembly support, thus improving safety during operation.

[0009] As a further improvement to the above technical solution, a first elastic pad is connected to the top side of the support plate. The first elastic pad can absorb and disperse the impact and vibration generated during the placement and movement of the bridge assembly, which helps to protect the bridge assembly from damage. It also protects the tooling itself and allows the support plate to adapt to bridge assemblies of different weights and shapes, providing uniform support force and better protecting the support position.

[0010] As a further improvement to the above technical solution, the slot is arc-shaped. The arc-shaped slot can better fit the shape of the wheel hub, thereby improving the stability and reliability of the wheel hub support. In addition, the arc-shaped slot can evenly distribute the weight and pressure of the wheel hub, reducing the risk of deformation or damage caused by concentrated loads and extending the service life of the tooling fixture.

[0011] As a further improvement to the above technical solution, a second elastic pad is connected to the tooling bracket at the inner wall of the slot. The second elastic pad provides cushioning performance for the tooling bracket when supporting the wheel hub at the slot position. The second elastic pad can absorb and disperse the impact and vibration generated during the placement and movement of the wheel hub, thereby protecting the wheel hub from damage. At the same time, it helps the tooling bracket to provide uniform support force to the axle assembly at the slot position, which helps to avoid damage to the tooling bracket caused by excessive local pressure.

[0012] As a further improvement to the above technical solution, the bottom side of the tooling frame has at least four downwardly protruding support legs. Positioning holes are provided on the bottom side of each support leg, and positioning pins are respectively provided on the top side of the tooling frame opposite to the positioning holes. The shape of the positioning pins matches the shape of the positioning holes they face. The support legs provide support for the entire tooling frame, and the multiple support legs can evenly distribute the weight and pressure of the bridge assembly, reducing the risk of deformation or damage caused by concentrated loads. Furthermore, in production, multiple tooling frames can be stacked vertically, and the positioning holes on the bottom side of the support legs and the positioning pins on the top side of the tooling frame can be used to securely connect adjacent tooling frames, thereby reducing horizontal space occupation and improving the space utilization rate of the factory premises.

[0013] As a further improvement to the above technical solution, the tooling frame is provided with multiple hooks on its outer side, with the hook openings of the hooks all facing downwards. When the tooling frame needs to be hoisted and stacked, the entire tooling frame can be hoisted up by the multiple hooks. Since the hook openings face downwards, when the tooling frame is hooked at the hook position, it can prevent the tooling frame from tilting or falling off during transportation, thus improving the safety and convenience of operation.

[0014] As a further improvement to the above technical solution, the bottom side of the tooling frame is provided with multiple forklift slots spaced apart along a straight line. The forklift slots can accommodate the fork arms of a forklift, enabling the tooling to be transported and moved by a forklift, reducing the labor intensity and operation time of workers during the handling process. Furthermore, the use of forklift slots improves the safety of the tooling frame during handling and movement, helping to prevent the tooling from tilting or falling off during handling.

[0015] As a further improvement to the above technical solution, the tooling frame is provided with telescopic components on both sides along the width direction. The tooling frame is provided with telescopic components on both sides along the width direction to provide support and positioning for the bridge assembly. When positioning the bridge assembly, two support plates provide support on both sides of the bridge assembly in the width direction, while two slots provide support from the length direction of the bridge assembly, thus improving the stability of the bridge assembly positioning.

[0026] Reference Figures 1 to 3 A paint protection device for axle assembly includes a tooling frame 100 and a telescopic component. The tooling frame 100 has slots 110 on both sides along its length, with the openings of the two slots 110 facing upwards. The telescopic component is located on one side of the tooling frame 100 along its width, and the telescopic component has a support plate 210 that can move up and down and be positioned.

[0027] As described above, the bridge assembly requiring repainting is placed on the tooling frame 100, and the wheel hubs inside the bridge assembly are placed in the corresponding slots 110. The slots 110 on both sides of the tooling frame 100 are used to position the wheel hubs of the bridge assembly, preventing them from moving or rotating during the repainting process, thus ensuring the accuracy and consistency of the repainting. Then, the height of the support plate 210 of the telescopic component is adjusted so that the support plate 210 abuts against the bridge assembly. This can adapt to different structural shapes of the bridge assembly and provide auxiliary support. This allows for quick and convenient lifting and positioning of the bridge assembly, reducing preparation time and facilitating comprehensive repainting repair of the bridge assembly. This improves the efficiency of subsequent repainting repair work on the bridge assembly, enhances work quality, reduces the need for rework and repairs, and lowers production costs.

[0028] The telescopic assembly mainly forms a structure for adjusting and positioning the support plate 210 vertically. For example, a vertical cylinder can be provided on the tooling frame 100, and multiple adjustment holes are provided vertically at intervals on the outside of the vertical cylinder. A vertical rod is inserted into the vertical cylinder, and the support plate 210 is connected to the top of the vertical rod. At this time, the position of the vertical rod is adjusted vertically to adjust the height of the support plate 210. After the adjustment is completed, an adjustment rod is inserted into at least one adjustment hole and inserted into the vertical rod to achieve mutual locking between the vertical rod and the vertical cylinder. In this embodiment, the telescopic assembly includes a sleeve 220 and a screw 230. The sleeve 220 is connected to the tooling frame 100 and extends in the vertical direction. The bottom of the screw 230 is threaded into the sleeve 220, and the support plate 210 is connected to the top of the screw 230. The height of the support plate 210 can be precisely adjusted according to actual needs through the cooperation of the sleeve 220 and the screw 230. Specifically, rotating the screw 230 can drive the support plate 210 to move up and down, thereby adapting to the height of different corresponding bridge assemblies. The threaded cooperation between the screw 230 and the sleeve 220 achieves self-locking, ensuring that the support plate 210 remains stable during the paint touch-up process and will not move or tilt due to external forces. This improves the stability and reliability of the tooling during use. This not only improves the adaptability of the tooling, but also makes the adjustment process simple and quick, reduces the operator's time and labor intensity, and ensures the accuracy and quality of the paint touch-up work.

[0029] Furthermore, a locking nut 240 is threadedly connected to the outer side of the screw 230, and the locking nut 240 abuts against the top of the sleeve 220. The locking nut 240 can firmly abut against the top of the sleeve 220, preventing the screw 230 from loosening or rotating during up and down movement. This locking mechanism ensures the stability of the support plate 210 during the paint touch-up process, further eliminating work errors caused by loose parts. Workers can fix or release the screw 230 by rotating the locking nut 240, thereby quickly adjusting the height of the support plate 210. This not only improves operating efficiency but also enhances the stability of the bridge assembly support, thereby improving safety during operation.

[0030] To provide elastic cushioning for the support plate 210 when supporting the bridge assembly, in this embodiment, a first elastic pad 250 is connected to the top side of the support plate 210. The first elastic pad 250 can absorb and disperse the impact and vibration generated during the placement and movement of the bridge assembly, which helps protect the bridge assembly from damage. It also protects the tooling itself and allows the support plate 210 to adapt to bridge assemblies of different weights and shapes, providing uniform support force and better protecting the support position.

[0031] Furthermore, the slot 110 is arc-shaped. The arc-shaped slot 110 can better fit the shape of the wheel hub, thereby improving the stability and reliability of the wheel hub support. In addition, the arc-shaped slot 110 can evenly distribute the weight and pressure of the wheel hub, reducing the risk of deformation or damage caused by concentrated loads and extending the service life of the tooling frame 100.

[0032] Similarly, to provide cushioning when the slot 110 supports the axle assembly, in this embodiment, a second elastic pad 120 is connected to the inner wall of the tooling frame 100 at the position of the slot 110. The second elastic pad 120 provides cushioning performance for the tooling frame 100 when supporting the wheel hub at the position of the slot 110. The second elastic pad 120 can absorb and disperse the impact and vibration generated during the placement and movement of the wheel hub, thereby protecting the wheel hub from damage. At the same time, it helps the tooling frame 100 to provide uniform support force to the axle assembly at the position of the slot 110, which helps to avoid damage to the tooling frame 100 due to excessive local pressure.

[0033] To facilitate centralized processing or storage of bridge assemblies, such as Figure 4 As shown, in this embodiment, the bottom side of the tooling frame 100 has at least four downwardly protruding support legs 130. Positioning holes are provided on the bottom side of each support leg 130. Positioning pins 140 are respectively provided on the top side of the tooling frame 100 opposite to the positioning holes. The shape of the positioning pins 140 matches the shape of the positioning holes they face. The support legs 130 support and support the entire tooling frame 100. The multiple support legs 130 can evenly distribute the weight and pressure of the bridge assembly, reducing the risk of deformation or damage caused by concentrated loads. Furthermore, in production, multiple tooling frames 100 can be stacked vertically. The positioning holes on the bottom side of the support legs 130 and the positioning pins 140 on the top side of the tooling frame 100 cooperate to securely connect adjacent tooling frames 100, thereby reducing horizontal space occupation and improving the space utilization rate of the factory.

[0034] In some embodiments, the tooling rack 100 is provided with a plurality of hooks 150 on its outer side, all of which have hook openings facing downwards. When the tooling rack 100 needs to be hoisted and stacked, the entire tooling rack 100 can be hoisted up by the plurality of hooks 150. Since the hook openings of the hooks 150 face downwards, when the tooling rack 100 is hoisted at the hook position, it can prevent the tooling rack 100 from tilting or falling off during transportation, thereby improving the safety and convenience of operation.

[0035] In some embodiments, the bottom side of the tooling frame 100 is provided with a plurality of forklift slots 160 spaced apart along a straight direction, and a fork opening is formed between the forklift slots 160 and the bottom side of the tooling frame 100. The fork opening can accommodate the fork arms of a forklift, enabling the tooling to be carried and moved by the forklift, reducing the labor intensity and operation time of workers during the handling process, and improving the safety of the tooling frame 100 during handling and movement by utilizing the forklift slots 160, which helps to prevent the tooling from tilting or falling off during handling.

[0036] In the above embodiments, the telescopic component can be provided on only one side of the tooling frame 100 along the width direction. However, in this embodiment, the telescopic components are provided on both sides of the tooling frame 100 along the width direction. The tooling frame 100 has telescopic components on both sides along the width direction that provide support and positioning for the bridge assembly. When positioning the bridge assembly, the two support plates 210 provide support on both sides of the bridge assembly in the width direction, while the two slots 110 provide support from the length direction of the bridge assembly, thus improving the stability of the bridge assembly positioning.

[0037] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
