Description

Technical Field

[0001] This utility model belongs to the technical field of spring processing equipment, specifically relating to an adaptive spring compression device. Background Technology

[0002] In the field of mechanical assembly, spring-type parts (such as compression springs) are one of the core foundations for realizing functions such as buffering, resetting, and sealing. Their assembly process is widely used in the production of products in industries such as automobiles, electronics, and home appliances.

[0003] However, existing spring compression assembly equipment usually relies on special fixtures for springs of a single specification. When it is necessary to switch to spring products of different diameters, the machine must be stopped to replace the corresponding fixture. This not only leads to long changeover times on the production line, but also increases the procurement and storage costs of fixtures in multi-specification production scenarios. Therefore, this phenomenon has become a problem that urgently needs to be solved by people in this field. Utility Model Content

[0007] The present invention further explains that both the first clamping block and the second clamping block are V-shaped with a right angle between the V-shapes. The first clamping block has two passageways on the side near the lower mold.

[0014] Please see Figure 1-4 The present invention provides a technical solution: an adaptive spring compression device, comprising a first cylinder 1, a frame 2 and a base 3. The first cylinder 1 is disposed above the frame 2 and the base 3. The frame 2 is fixedly connected to the base 3. A lower mold 4 is fixedly connected to the base 3. A double V mechanism 5 is disposed on the lower mold 4. The double V mechanism 5 includes a first clamping block 8 and a second clamping block 9. The first clamping block 8 and the second clamping block 9 are slidably connected to the lower mold 4. A spring (not shown in the figure) is disposed between the first clamping block 8 and the second clamping block 9.

[0015] A second cylinder 6 is fixedly connected to the corner of the first clamping block 8, and a third cylinder 7 is fixedly connected to the corner of the second clamping block 9. Both the second cylinder 6 and the third cylinder 7 are fixedly connected to the lower mold 4. By driving the second cylinder 6 and the third cylinder 7 to operate, the first clamping block 8 and the second clamping block 9 are driven to move towards each other.

[0016] Both the first clamping block 8 and the second clamping block 9 are V-shaped with a right angle between them. The first clamping block 8 has two passages 10 on the side closest to the lower mold 4. The two passages 10 are located on the two sides of the first clamping block 8, and each passage 10 is rectangular with a length less than the length of a single side of the V-shape.

[0017] Two passageways 11 are provided on the side of the second clamping block 9 away from the lower mold 4. The two passageways 11 are located on the two sides of the second clamping block 9 respectively. Each passageway 11 is rectangular and its length is less than the length of one side of the V-shape. The height of passageway 10 is equal to the height of the V-shape of the second clamping block 9. When clamping the spring, the first clamping block 8 and the second clamping block 9 intersect each other.

[0018] A groove 12 is provided on the side of the lower mold 4 away from the frame 2. The groove 12 is slidably connected to the first clamping block 8 and the second clamping block 9. The shape of the side of the groove 12 facing the second clamping block 9 is adapted to the shape of the second clamping block 9, and the shape of the side of the groove 12 facing the first clamping block 8 is adapted to the shape of the first clamping block 8.

[0019] Guide pillars 13 are fixedly connected to the four corners of the base support 3. A fixing plate 14 is bolted to the section of the guide pillar 13 away from the base support 3. The fixing plate 14 is fixedly connected to the first cylinder 1. The push rod of the first cylinder 1 passes through the fixing plate 14 and is fixedly connected to the upper support 15. The four corners of the upper support 15 are slidably connected to the guide pillars 13. An upper mold (not shown in the figure) is fixedly connected to the side of the upper support 15 near the double V mechanism 5. By driving the first cylinder 1 to operate, the push rod drives the upper support 15 to move along the guide pillars 13 toward the lower mold 4.

[0020] Working principle: The spring to be compressed is placed between the first clamping block 8 and the second clamping block 9. The second cylinder 6 and the third cylinder 7 are driven to operate, thereby causing the first clamping block 8 and the second clamping block 9 to slide towards each other in the groove 12. The V-shaped angle is used to center and clamp the spring. The passage 10 of the first clamping block 8 and the passage 11 of the second clamping block 9 intersect each other to avoid mutual interference. At the same time, it can adapt to springs of different diameters. The shape of the groove 12 adapts to maintain a stable sliding trajectory for the first clamping block 8 and the second clamping block 9. After centering and clamping, the first cylinder 1 is driven to operate, and the push rod drives the upper support 15 to move down along the guide post 13. The upper mold moves towards the spring synchronously with the upper support 15 to complete the compression action of the spring. Finally, the automatic centering of the double V mechanism 5 is achieved. The cross clamping is interference-free and can be adapted to the centering and clamping of springs of multiple specifications.
