Technical Field

[0001] The present invention relates to the technical field of tooling fixtures, and particularly relates to a method for using a tooling fixture for spring assembly. Background Art

[0002] A spring is a mechanical part that utilizes elasticity. A part made of an elastic material deforms under an external force and returns to its original shape after the external force is removed. Also known as a "spring". Generally made of spring steel. Springs come in a complex variety of types. Classified by shape, there are mainly helical springs, scroll springs, leaf springs, special-shaped springs, etc.

[0003] The springs assembled by existing spring assembly tooling fixtures have a small initial tension, weak anti-fatigue ability, a narrow application range, and are prone to damage. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a method for using a tooling fixture for spring assembly, which can assemble springs with a large initial tension and strong anti-fatigue ability, has good use effects, and has a simple assembly method and strong practicability.

[0005] To solve the above technical problem, the present invention provides a method for using a tooling fixture for spring assembly. The tooling fixture includes a clamping mechanism and an assembly mechanism. The clamping mechanism includes symmetrically arranged fixing plates. Each fixing plate is provided with a clamping block. A placing plate is arranged between the clamping blocks. First fixing blocks and second fixing blocks are further arranged on both sides of the fixing plates. A first limiting device is arranged on the first fixing block, and a second limiting device is arranged on the second fixing block. A moving device is arranged between one of the fixing plates and the clamping block; the first limiting device includes

[0006] a first fixture, the second limiting device includes a second fixture. The first fixture and the second fixture have the same structure. A long arm and a short arm are integrally arranged on the first fixture. Positioning columns are arranged on both the long arm and the short arm; the assembly mechanism includes an inclined shim and spring fixing blocks arranged on both sides of the inclined shim; corresponding grooves for the spring are arranged on the opposite surfaces of the two clamping blocks; grooves corresponding to the spring are arranged on the placing plate;

[0007] The using method includes the following steps:

[0008] Step 1: Fix the first spring in the clamping mechanism, and adjust the position and stretching degree of the first spring by using the first limiting device and the second limiting device on both sides; Step 2: Start the moving device to fix and limit the first spring. After the fixation is completed, remove the first limiting device and the second limiting device; Step 3: Insert the assembly mechanism into the first spring, and tap the inclined wedge to fix the first spring on the spring fixing block; Step 4: Start the moving device to separate the clamping blocks, and take out the assembly mechanism. At this time, the spring is fixed on the spring fixing block; Step 5: Repeat the first step and the second step to fix the second spring; Step 6: Insert the assembly mechanism with the first spring into the second spring, and then rotate the spring fixing block to tighten the first spring and the second spring; Step 7: Start the moving device to separate the clamping blocks, and take out the assembled spring, which is composed of the first spring and the second spring together.

[0009] Further, a through hole is provided at the center of the first fixing block. The first limiting device includes a first threaded rod and a first clamp. The first threaded rod passes through the through hole, and a first nut and a limiting block are respectively provided on both sides of the through hole. The limiting block is arranged between the first clamp and the through hole.

[0010] Further, a through hole is provided at the center of the second fixing block. The second limiting device includes a second threaded rod and a second clamp. The second threaded rod passes through the through hole. The second threaded rod is provided with a gear and a second nut on the side far

[0012] Further, the moving device includes a bolt and a screw rod. The screw rod penetrates through the fixing plate and one end abuts against the clamping block.

[0013] Further, a limiting screw is also provided between the fixing plate and the clamping block.

[0014] The beneficial effects of the present invention: This device first clamps the spring by using the clamping mechanism, and uses the assembly mechanism to clamp the spring on the spring fixing block on the assembly mechanism. Then, repeat the first step to fix the second spring. Once again, send the assembly mechanism into the clamping mechanism (at this time, the first spring has been fixed on the assembly mechanism), and tighten the two springs, so that the assembled spring has a large initial tension and strong anti-fatigue ability.

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the embodiments cited are not intended to limit the present invention.

[0023] Refer to Figures 1 to 3 As shown, an embodiment of the use method of a tooling fixture for spring assembly of the present invention includes a clamping mechanism and an assembly mechanism. The clamping mechanism includes symmetrically arranged fixed plates 1, and each fixed plate 1 is provided with a clamping block 2. A placing plate 3 is arranged between the clamping blocks 2. The two sides of the fixed plate 1 are also provided with a first fixing block 4 and a second fixing block 5. A first limiting device 6 is arranged on the first fixing block 4, and a second limiting device 7 is arranged on the second fixing block 5. A moving device 8 is arranged between one of the fixed plates 1 and the clamping block 2; the assembly mechanism includes an inclined shim 9 and spring fixing blocks 10 arranged on both sides of the inclined shim 9.

[0024] During use, first place the spring on the clamping mechanism, use the first limiting device 6 and the second limiting device 7 to limit both sides of the spring, stretch the spring to a certain position and fix it, and use the moving device 8 to move the clamping block 2 to clamp the spring to limit the horizontal position of the spring. After clamping, remove the first limiting device 6 and the second limiting device 7. At this time, insert the inclined shim 9 into the fixed spring, tap the inclined shim 9 to make it penetrate into the clamping mechanism to fix the spring on the spring fixing block 10. Then start the moving device 8 to take out the spring fixed on the spring fixing block 10. Then continue to repeat the process of fixing the next spring. After fixing is completed, insert the inclined shim 9 into the fixed spring again (at this time, the spring fixing block 10 has already fixed the previous spring), rotate the inclined shim 9 to tighten the two springs, and then move the moving mechanism again to take out the assembled spring.

[0025] A through hole is provided at the center of the first fixing block 4. The first limiting device 6 includes a first threaded rod 61 and a first clamp 62. The first threaded rod 61 passes through the through hole, and a first nut 63 and a limiting block 64 are respectively arranged on both sides of the through hole. The limiting block 64 is arranged between the first clamp 62 and the through hole. A through hole is provided at the center of the second fixing block 5. The second limiting device 7 includes a second threaded rod 71 and a second clamp 72. The second threaded rod 71 passes through the through hole. A gear 73 and a second nut 74 are arranged on the side of the second threaded rod 71 away from the second clamp 72. The first clamp 62 and the second clamp 72 have the same structure. An elongated arm 11 and a short arm 12 are integrally arranged on the first clamp 62. Positioning posts 13 are arranged on both the elongated arm 11 and the short arm 12. The first clamp 62 and the second clamp 72 are arranged oppositely and rotated by 90 degrees. The elongated arm 11 and the short arm 12 are used in cooperation and just adapt to the spring. The spring is clamped by the positioning posts 13 to prevent it from falling. After the clamping is completed, the position of the first threaded rod 61, that is, the position of the first clamp 62, is locked by the first nut 63. At this time, the gear 73 can be rotated by means of chain drive or the like. The rotation of the gear 73 drives the rotation of the second threaded rod 71 to control the fixed position and the stretching degree of the spring. After the fixing is completed, the drive can be cancelled.

[0026] Grooves corresponding to the spring are provided on the opposite surfaces of the two clamping blocks 2. Similarly, grooves corresponding to the spring are provided on the placing plate 3, which better adapts to the spring and also achieves a better fixing effect.

[0027] The moving device 8 includes a bolt 81 and a screw rod 82. The screw rod 82 passes through the fixing plate 1 and one end abuts against the clamping block 2. Rotating the bolt 81 can drive the screw rod 82 to move up and down in the fixing plate 1, that is, drive the clamping block 2 to move up and down. A limiting screw 14 is also arranged between the fixing plate 1 and the clamping block 2 to prevent the clamping block 2 from moving left and right while moving up and down, resulting in positioning deviation.

[0028] The usage method includes the following steps:

[0029] Step 1: Fix the first spring in the clamping mechanism, and adjust the position and stretching degree of the first spring by using the first limiting device 6 and the second limiting device 7 on both sides; Step 2: Start the moving device 8 to fix and limit the first spring. After the fixation is completed, remove the first limiting device 6 and the second limiting device 7; Step 3: Insert the assembling mechanism into the first spring, and tap the inclined shim 9 to fix the first spring on the spring fixing block 10; Step 4: Start the moving device 8 to separate the clamping blocks 2, and take out the assembling mechanism. At this time, the spring is fixed on the spring fixing block 10; Step 5: Repeat the first step and the second step to fix the second spring; Step 6: Insert the assembling mechanism with the first spring into the second spring, and then rotate the spring fixing block 10 to tighten the first spring and the second spring; Step 7: Start the moving device 8 to separate the clamping blocks 2, and take out the assembled spring, which is composed of the first spring and the second spring together.
