Description

Technical Field

[0001] This application relates to the technical field of constant velocity joint manufacturing, and particularly to a powder spraying fixture for a constant velocity joint. Background Art

[0002] With the rapid development of the automotive industry, the performance requirements for automotive constant velocity drive shafts are also constantly increasing. Especially the performance stability in salt spray corrosion resistance and other harsh environments has become an important standard for measuring the quality of automotive constant velocity drive shafts. Although the traditional painting process can meet the anti-corrosion requirements of constant velocity drive shaft components to a certain extent, there are limitations in aspects such as coating quality, adhesion, and durability. Especially in harsh environments such as high humidity and high salt spray, the coating is prone to peeling and rusting, resulting in a decline in the performance of the constant velocity drive shaft.

[0003] Therefore, in order to meet the high-performance requirements of automotive constant velocity drive shafts, the on-line electrostatic powder spraying process has become an effective solution. The on-line electrostatic powder spraying process has the advantages of uniform coating, strong adhesion, and good corrosion resistance, and can significantly improve the anti-corrosion performance and service life of the constant velocity drive shaft.

[0004] However, in the on-line electrostatic powder spraying operation of related technologies, the constant velocity joint is hung on the powder spraying fixture, and the contact part between the constant velocity joint and the fixture is easily sprayed with powder. As a result, in the next cycle of use of the fixture, due to the inability of the constant velocity joint and the fixture to conduct electricity normally, there are quality problems such as uneven powder spraying and missed spraying in the powder spraying of the constant velocity joint.

[0005] Therefore, how to improve the powder spraying quality of the constant velocity joint is a technical problem that needs to be solved by those skilled in the art at present. Utility Model Content

The hanging plate 1 is made of steel plate, and the suspension rod 2 is made of steel bar. The hanging plate 1 is fixed to the upper end of the suspension rod 2. The hanging plate 1 can be hung on the hook on the powder spraying production line. In the embodiment of the present application, the suspension rod 2 and the hanging plate 1 are fixedly connected by welding. In other embodiments of the present application, they are fixedly connected by screw fastening or riveting. Several groups of support assemblies 3 are fixed on the suspension rod 2 at a certain interval. In the embodiment of the present application, there are three groups of support assemblies. In other embodiments of the present application, there are four or five groups, which are set according to the size of the spray range of the powder spraying production line nozzle. The support assembly 3 includes a support frame 31, a limit sleeve 32 and a conductive member. The limit sleeve 32 is fixed on the support frame 31. The support frame 31 is used to support the constant velocity joint 6 to be powder sprayed. The constant velocity joint 6 to be powder sprayed can be covered on the limit sleeve 32. The conductive member is arranged in the limit sleeve 32 and can contact the inner wall of the constant velocity joint 6 to be powder sprayed. In this way, during powder spraying, the conductive member is not easily sprayed with powder under the cover of the constant velocity joint and the limit sleeve 32, improving the conductivity between the conductive member and the constant velocity joint 6 to be powder sprayed, and helping to improve the powder spraying quality of the constant velocity joint.

[0041] Refer to Figure 2 , in the embodiment of the present application, the conductive member is a conductive spring 33. One end of the conductive spring 33 is fixed on the limit sleeve 32 or the support frame 31, and the other end can elastically support on the inner wall of the constant velocity joint 6 to be powder sprayed. One end of the conductive spring 33 can be fixed on the limit sleeve 32 or the support frame 31 by welding, or fixedly connected by screw fastening or riveting, etc. As long as the conductivity between the support frame 31 and the constant velocity joint 6 can be guaranteed. In this way, the conductive spring 33 can support on the inner wall of the constant velocity joint by elastic force, can be applicable to constant velocity joints of different specifications, and can improve the reliability of the contact between the conductive spring 33 and the inner wall of the constant velocity joint, thereby improving the conductivity between the conductive spring 33 and the inner wall of the constant velocity joint. In other embodiments of the present application, it is a conductive elastic wire. One end of the elastic wire is fixed on the limit sleeve 32 or the support frame 31 by welding, and the free end can elastically support on the inner wall of the constant velocity joint.

[0042] Refer to Figure 2 , the powder spraying hanger for a constant velocity joint further includes a sealing assembly 4. The sealing assembly 4 is used to seal the opening of the constant velocity joint 6 to be powder sprayed. The sealing assembly 4 is sleeved on the limit sleeve 32 and supported on the support frame 31. In this way, the opening of the constant velocity joint 6 covered on the limit sleeve 32 is sealed by the sealing assembly 4, and the inner wall of the constant velocity joint and the conductive member are in a sealed state. During powder spraying, it helps to prevent powder from entering the conductive member, helps to improve the reliability of the conductive member's conductivity, and at the same time, helps to prevent powder from entering the inner wall of the constant velocity joint and causing pollution.

[0043] Refer to Figure 2, the sealing assembly 4 includes an elastic pad 41. The elastic pad 41 is provided with a first through hole 411. The first through hole 411 penetrates through the limit sleeve 32. One side of the elastic pad 41 supports on the support frame 31, and the other side is used to support the powder-spraying cage 6 sleeved on the limit sleeve 32, which helps to improve the sealing effect of the elastic pad 41 on the cage opening, making it not easy for powder to enter the inside of the cage. The elastic pad 41 is made of a heat-resistant silicone pad, and the high-temperature resistant range of the heat-resistant silicone pad is between 200°C and 300°C, which helps to improve the service life of the elastic pad 41 and the reliability of the cage sealing.

[0044] Refer to Figure 2 , the sealing assembly 4 further includes a support pad 42. The support pad 42 is provided with a second through hole 421. The second through hole 421 penetrates through the limit sleeve 32. One side of the support pad 42 supports on the support frame 31, and the other side supports the elastic pad 41. In this way, when the powder-spraying cage 6 is covered on the elastic pad 41, it can make the other side of the elastic pad 41 in a flat state, which helps to improve the uniform contact of the elastic pad 41 with the opening of the powder-spraying cage 6 and improve the sealing effect of the elastic pad 41.

[0045] Refer to Figure 3 , the support frame 31 is a reticular structure welded by steel bars. The reticular structure includes two long sides 311 and two short sides 312. The two long sides 311 are symmetrically arranged on both sides of the suspension rod 2. The two limit sleeves 32 are fixed on the long sides 311. The support frame 31 being a reticular structure welded by steel bars can help reduce the weight of the support frame 31 while ensuring the strength of the support frame 31. The reticular structure includes two long sides 311 and two short sides 312. The two long sides 311 are symmetrically arranged on both sides of the suspension rod 2. The two limit sleeves 32 are fixed on the long sides 311, which helps to improve the hanging stability of the hanger. At the same time, placing two powder-spraying cages 6 on each support frame 31 helps to improve the production efficiency of powder spraying. The support frame 31 further includes two diagonal tension rods 313. One end of the diagonal tension rod 313 is fixed on the suspension rod 2, and the other end is fixed on the outer edge of the short side 312, which helps to improve the connection reliability between the support frame 31 and the suspension rod 2.

[0046] Refer to Figure 2 , the powder-spraying cage hanger further includes a short shaft sleeve 5. One end of the short shaft sleeve 5 is a closed end, and the other end is an open end. The open end is sleeved on the short shaft of the powder-spraying cage 6. In this way, the short shaft of the cage that does not need powder spraying is in a closed state, which helps to improve the protection of the parts that do not need powder spraying. The short shaft sleeve 5 is made of nylon material, which helps to reduce the weight of the short shaft sleeve 5 and improve the convenience of the operation of taking and placing the short shaft sleeve 5.

[0047] The process of using a powder spraying fixture for a constant velocity joint is as follows: Hang the hanging plate 1 of the powder spraying fixture for the constant velocity joint on the hook of the powder spraying production line. Sequentially put on the support pad 42 and the elastic pad 41 on the limit sleeve 32. Cover the constant velocity joint 6 to be powder sprayed on the limit sleeve 32, so that the opening of the constant velocity joint 6 to be powder sprayed is covered with the elastic pad 41. The conductive spring 33 contacts the inner wall of the constant velocity joint 6 to be powder sprayed. Install the short shaft sleeve 5 on the short axis of the constant velocity joint 6 to be powder sprayed. The constant velocity joint 6 to be powder sprayed and the fixture enter the powder spraying operation area of the production line for powder spraying operation together. After powder spraying, sequentially remove the short shaft sleeve 5 and the powder sprayed constant velocity joint, and then perform the operation of the next powder spraying cycle.
