Suspension coil spring painting hanger

Abstract

This utility model relates to a suspension coil spring coating fixture, belonging to the technical field of coating fixtures. It includes a main hanging rod, with multiple part hook assemblies detachably connected to both sides of the main hanging rod. These part hook assemblies are used to suspend the suspension coil springs. Each part hook assembly includes a V-shaped hook and a connecting block, which are fixedly connected. The V-shaped hook has a V-shaped body and a square cross-section. During suspension, the edges of the square cross-section contact the spring, reducing the contact area between the fixture and the spring, thereby minimizing the impact of the hooking point on the powder coating process. This suspension coil spring coating fixture, by setting multiple part hook assemblies on the main hanging rod, increases the number of springs that can be suspended, thus improving the powder coating efficiency of the coating production line. Simultaneously, by setting the V-shaped hook with a square cross-section, the contact area between the fixture and the spring is reduced, thereby minimizing the impact of the hooking point on the powder coating process.

Description

Technical Field

[0001] The utility model relates to a suspension coil spring painting fixture, belonging to the technical field of painting fixtures. Background Art

[0002] The suspension coil spring is an important component of the vehicle suspension system, which can effectively absorb and mitigate the impact and vibration transmitted from the road surface to the vehicle body, reduce the jolting of the vehicle body, and provide a comfortable driving experience for the driver and passengers. During the production process of the suspension coil spring, powder coating treatment is required to avoid rusting.

[0003] With the rapid development of the automotive industry, the demand for suspension coil springs is increasing. However, the existing suspension coil spring painting fixtures can only hang a single spring, and the number of springs that can be hung is small, seriously affecting the powder coating efficiency of the painting production line. Therefore, in order to meet the product delivery deadlines of customers, a new type of painting fixture is urgently needed to improve the powder coating efficiency. Content of the Utility Model

[0004] Based on the above deficiencies in the prior art, the technical problem to be solved by the utility model is: to provide a suspension coil spring painting fixture, which can increase the number of springs that can be hung and improve the powder coating efficiency of the painting production line.

[0005] The suspension coil spring painting fixture of the utility model includes a main hanging rod. A plurality of part hanging hook assemblies are detachably connected to both sides of the main hanging rod. The part hanging hook assemblies are used for hanging suspension coil springs. The part hanging hook assembly includes a V-shaped hook and a connecting block, and the V-shaped hook and the connecting block are fixedly connected. The hook body of the V-shaped hook is in a V-shaped structure, and the cross-section of the V-shaped hook is square. When hanging, the edge of the square cross-section contacts the spring, reducing the contact area between the fixture and the spring, thereby reducing the influence of the hanging point on the powder coating work.

[0006] The technical solution of the utility model is to provide a suspension coil spring painting fixture. By arranging a plurality of part hanging hook assemblies on the main hanging rod, the number of springs that can be hung is increased to improve the powder coating efficiency of the painting production line. At the same time, by setting a V-shaped hook with a square cross-section, the contact area between the fixture and the spring is reduced, thereby reducing the influence of the hanging point on the powder coating work.

[0007] Preferably, the main hanging rod includes a vertical rod and two horizontal rods, and the vertical rod and the two horizontal rods form an inverted "dry" character structure.

[0008] Preferably, the part hanging hook assembly is detachably connected to the horizontal rod through bolts and nuts. A through activity groove is provided on the horizontal rod to facilitate adjusting to a suitable spacing according to the size of the part.

[0009] Preferably, a main hanging hook is provided at the top of the vertical rod, and the main hanging hook is used for hanging with the conveying system of the painting production line.

[0010] Preferably, the included angle of the V-shaped structure of the V-hook is 45 degrees.

[0011] Preferably, the bottom of the connecting block is provided with an arc-shaped groove so that it can fit tightly with the crossbar after installation and prevent swaying; the connecting block is also provided with through bolt holes.

[0012] The advantages of this utility model compared with the prior art are:

[0013] The suspension helical spring coating fixture of this utility model increases the number of springs that can be suspended by setting multiple part hook assemblies on the main body of the hanging rod, thereby improving the powder coating efficiency of the coating production line; at the same time, by setting V-shaped hooks with square cross-sections, the contact area between the fixture and the spring is reduced, thereby reducing the impact of the hanging point on the powder coating work.

[0019] Example 1

[0020] like Figures 1-3 As shown, this embodiment is achieved through the following technical solution: it includes a hanging rod body 2, and four part hook assemblies 3 are detachably connected to both sides of the hanging rod body 2. The part hook assemblies 3 are used to suspend the suspension coil springs. The part hook assemblies 3 include V-shaped hooks 31 and connecting blocks 32, and the V-shaped hooks 31 and connecting blocks 32 are fixedly connected. The hook body of the V-shaped hook 31 has a V-shaped structure and the cross-section of the V-shaped hook 31 is square. When suspended, the edges of the square cross-section contact the spring, reducing the contact area between the hanger and the spring, thereby reducing the impact of the hanging point on the powder coating process.

[0021] In this embodiment, the hanging rod main body 2 includes a vertical rod 21 and two cross rods 22. The vertical rod 21 and the two cross rods 22 form an inverted "dry" - shaped structure. The part hook assembly 3 is detachably connected to the cross rod 22 through bolts and nuts; a through - going movable groove 221 is provided on the cross rod 22 to facilitate adjusting the appropriate spacing according to the size of the parts. A main hook 1 is provided at the top of the vertical rod 21, and the main hook 1 is used for hanging on the conveying system of the painting production line.

[0022] The included angle of the V - shaped structure of the V - shaped hook 31 is 45 degrees; an arc - shaped groove 322 is provided at the bottom of the connecting block 32 to facilitate close fitting with the cross rod 22 after installation and prevent swinging; a through - going bolt hole 321 is also provided on the connecting block 32.

[0023] The usage method of the present utility model is as follows:

[0024] Hang the position of 0.5 turns of the end of the suspension spiral spring on the V - shaped structure of the V - shaped hook 31. The edge of the V - shaped hook 31 contacts the suspension spiral spring, reducing the contact area between the hanger and the spring, thereby reducing the influence of the hanging point on the powder coating work; each set of hangers can hang four suspension spiral springs, increasing the number of springs that can be hung, and thus improving the powder coating efficiency.
