Description

Technical Field

[0001] This utility model relates to the field of testing tooling technology, specifically a tooling for testing the spacing distance of leaf springs. Background Technology

[0002] Leaf springs are a common type of mechanical elastic element widely used in vehicle suspension systems. They are mainly used to support the weight of the vehicle body, buffer road impacts, and maintain driving stability. They are usually made up of multiple spring steel plates of different lengths stacked together and fixed to the axle with U-bolts. The ends are designed with lugs or bushings to connect to the frame. Their working principle is to use the elastic deformation of the spring steel to absorb vibration energy, converting the vertical impact force into elastic potential energy, and then slowly releasing it to reduce vehicle body bumps. When installing leaf springs, it is usually necessary to measure the spacing between the leaf spring plates to ensure that it meets the manufacturing standards.

[0003] In the prior art, rulers or vernier calipers are generally used to measure the distance between leaf springs. However, since there are multiple leaf springs, multiple measurements are required when using rulers or vernier calipers, which is inconvenient. Therefore, a fixture for detecting the distance between leaf springs is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling for detecting the spacing between leaf springs, so as to solve the problem of inconvenience in detecting the spacing between existing leaf springs mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fixture for detecting the interval distance of a leaf spring includes two symmetrically arranged scale slide rails. A sliding positioning component is installed on the inner side of the scale slide rails. A connecting block is installed at the bottom end of the sliding positioning component. A positioning plate is fixedly connected to the bottom end of the connecting block. A pointer is fixedly connected to the outer side of the positioning plate. A horizontally arranged pressure plate is provided above the sliding positioning component and located inside the scale slide rails. A fixing plate is fixedly connected to the top end of the pressure plate. Reset components are symmetrically installed at the front and rear ends of the fixing plate. A plurality of first connecting brackets are fixedly connected to the top end of the fixing plate. A ring is fixedly connected to the inner side of each first connecting bracket. A second connecting bracket is fixedly connected between the two scale slide rails below the first connecting brackets. A threaded ring is fixedly connected to the inner side of the second connecting bracket. A bolt is provided inside the ring.

[0007] Preferably, multiple sets of the sliding positioning components are provided, with each set consisting of two components. The pointer is located on the outside of the scale slide rail, and the bolt is located on the inside of the threaded ring and is threadedly connected to the threaded ring.

[0008] Preferably, the sliding positioning assembly includes a top plate disposed inside the scale slide rail, a symmetrically arranged limiting rod fixedly connected to the bottom end of the top plate, a limiting spring disposed outside the limiting rod, and a bottom plate fixedly connected to the bottom end of the limiting spring.

[0009] Preferably, the top end of the limiting spring is fixedly connected to the bottom end of the top plate, the limiting rod passes through the bottom plate and is slidably connected to the bottom plate, and the bottom end of the bottom plate is fixedly connected to the top end of the connecting block.

[0010] Preferably, the top end of the top plate is in close contact with the bottom end of the pressing plate, and the bottom end of the limiting rod is in close contact with the bottom end of the inner side of the scale slide rail.

[0011] Preferably, the reset assembly includes a connecting plate fixedly connected to one end of the scale slide rail, a vertically arranged connecting rod fixedly connected to the top of the connecting plate, a reset spring provided on the outside of the connecting rod, and a baffle fixedly connected to the top of the connecting rod.

[0012] Preferably, the connecting rod passes through the fixing plate and is slidably connected to the fixing plate, the bottom end of the reset spring is fixedly connected to the connecting plate, and the top end of the reset spring is fixedly connected to the bottom end of the fixing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by setting a scale slide rail, connecting block, positioning plate, pointer, pressing plate, fixing plate, first connecting frame, ring, second connecting frame, threaded ring and bolt, the device can be adjusted according to the required interval distance of the leaf springs before use, and the pressing plate and fixing plate are fixed with bolts. When using the device, each set of positioning plates can be inserted into the gap between two leaf springs to determine whether the leaf springs are qualified. This design makes the detection of the leaf spring interval distance more convenient, eliminating the need for operators to perform single measurements and improving work efficiency.

[0015] 2. In this utility model, the sliding positioning component, top plate, limiting rod, limiting spring, and bottom plate allow for upward adjustment of the positioning plate when the distance between the positioning plates is adjusted. This causes the limiting spring to compress, and after adjustment, the positioning plate is released, allowing the limiting spring to reset and tightly engage with the bottom of the bottom plate against the inner bottom of the scale slide rail. The sliding positioning component provides initial positioning of the positioning plate, preventing it from shifting due to vibration during bolt installation. 3. In this utility model, the reset component, connecting plate, connecting rod, reset spring, and baffle allow for testing of different types of leaf springs. When the bolts are removed, the reset spring resets, causing the fixing plate and clamping plate to move upward. This design prevents the clamping plate from remaining above the sliding positioning component when adjusting the distance between the positioning plates, thus avoiding significant resistance and inconvenience in adjusting the positioning plates.

[0027] Please see Figure 1-7 This utility model provides a technical solution:

[0028] A fixture for detecting the interval distance of a leaf spring includes two symmetrically arranged scale slide rails 1. A sliding positioning component 2 is installed on the inner side of the scale slide rail 1. A connecting block 3 is installed at the bottom end of the sliding positioning component 2. A positioning plate 4 is fixedly connected to the bottom end of the connecting block 3. A pointer 5 is fixedly connected to the outer side of the positioning plate 4. A horizontally arranged pressure plate 6 is provided above the sliding positioning component 2 and located inside the scale slide rail 1. A fixing plate 7 is fixedly connected to the top end of the pressure plate 6. Reset components 8 are symmetrically installed at the front and rear ends of the fixing plate 7. Multiple first connecting brackets 9 are fixedly connected to the top end of the fixing plate 7. A ring 10 is fixedly connected to the inner side of the first connecting bracket 9. A second connecting bracket 11 is fixedly connected between the two scale slide rails 1 below the first connecting bracket 9. A threaded ring 12 is fixedly connected to the inner side of the second connecting bracket 11. A threaded ring 12 is fixedly connected to the inner side of the ring 10. Bolt 13 and sliding positioning components 2 are arranged in multiple sets of two. Pointer 5 is set on the outside of scale slide rail 1, and bolt 13 is set on the inside of threaded ring 12 and threadedly connected to threaded ring 12. Through the scale slide rail 1, connecting block 3, positioning plate 4, pointer 5, clamping plate 6, fixing plate 7, first connecting frame 9, ring 10, second connecting frame 11, threaded ring 12 and bolt 13, the device can be adjusted according to the required leaf spring interval before use, and the clamping plate 6 and fixing plate 7 are fixed with bolt 13. When using the device, each pair of positioning plates 4 can be inserted into the gap between two leaf springs to determine whether the leaf springs are qualified. This design makes the leaf spring interval distance detection more convenient, eliminating the need for operators to perform single measurements and improving work efficiency.

[0029] The sliding positioning assembly 2 includes a top plate 21 located inside the scale slide rail 1. A symmetrically arranged limiting rod 22 is fixedly connected to the bottom end of the top plate 21. A limiting spring 23 is provided on the outer side of the limiting rod 22. A bottom plate 24 is fixedly connected to the bottom end of the limiting spring 23. The top end of the limiting spring 23 is fixedly connected to the bottom end of the top plate 21. The limiting rod 22 passes through the bottom plate 24 and is slidably connected to it. The bottom end of the bottom plate 24 is fixedly connected to the top end of the connecting block 3. The top end of the top plate 21 is tightly fitted to the bottom end of the pressing plate 6. The bottom end of the limiting rod 22 is connected to the scale slide rail. The inner bottom end is tightly fitted. Through the set sliding positioning component 2, top plate 21, limit rod 22, limit spring 23 and bottom plate 24, when adjusting the distance between the positioning plates 4, the positioning plates 4 are pushed upward, so that the limit spring 23 is compressed. After the adjustment is completed, the positioning plates 4 are released, and the limit spring 23 returns to its original position, causing the bottom end of the bottom plate 24 to be tightly fitted with the inner bottom end of the scale slide rail 1. The setting of the sliding positioning component 2 can perform preliminary positioning of the positioning plates 4 and prevent the positioning component from being moved or offset by vibration when installing the bolts 13.

[0030] The reset assembly 8 includes a connecting plate 81 fixedly connected to one end of the scale slide rail 1. A vertically arranged connecting rod 82 is fixedly connected to the top of the connecting plate 81. A reset spring 83 is provided on the outside of the connecting rod 82. A baffle 84 is fixedly connected to the top of the connecting rod 82. The connecting rod 82 passes through the fixed plate 7 and is slidably connected to the fixed plate 7. The bottom end of the reset spring 83 is fixedly connected to the connecting plate 81, and the top end of the reset spring 83 is fixedly connected to the bottom end of the fixed plate 7. Through the reset assembly 8, connecting plate 81, connecting rod 82, reset spring 83 and baffle 84, when different models of leaf springs need to be tested, the bolt 13 is removed. At this time, the reset spring 83 resets and drives the fixed plate 7 and the pressure plate 6 to move upward. This design can prevent the pressure plate 6 from still being above the sliding positioning assembly 2 when adjusting the distance between the positioning plates 4, which would cause the adjustment of the positioning plates 4 to have great resistance and be inconvenient.

[0031] Workflow: When the device is needed, adjust it according to the required spacing of the leaf springs. First, push the positioning plate 4 at the bottom of the connecting block 3 upward, so that the bottom plate 24 slides upward outside the limiting rod 22. The limiting spring 23 at the bottom of the top plate 21 is compressed. At this time, the positioning plate 4 can be pushed, and the position of the pointer 5 outside the scale slide rail 1 can be observed to match the distance between the two positioning plates 4 with the spacing of the leaf springs. Then, release the positioning plate 4, and the limiting spring 23 at the bottom of the top plate 21 will return to its original position, causing the bottom plate 24 to slide downward outside the limiting rod 22 until the top of the top plate 21 is tightly fitted with the top of the inner side of the scale slide rail 1. The bottom end of the base plate 24 is tightly fitted with the inner bottom end of the scale slide rail 1. The sliding positioning component 2 can initially position the positioning plate 4, preventing the positioning component from being moved or shifted due to vibration when installing the bolt 13. After all the positioning plates 4 have been adjusted, the bolt 13 is inserted into the ring 10 on the first connecting frame 9 and screwed into the threaded ring 12 of the second connecting frame 11, causing the fixing plate 7 to drive the pressing plate 6 to descend. When the pressing plate 6 contacts the top plate 21, the top plate 21 descends until the top end of the top plate 21 is tightly fitted with the bottom end of the pressing plate 6, and the bottom end of the limiting rod 22 is tightly fitted with the inner bottom end of the scale slide rail 1. During the process, the fixing plate 7 slides outside the connecting rod 82 at the bottom of the baffle 84, and the return spring 83 at the top of the connecting plate 81 is compressed. At this time, the clamping plate 6 can clamp and fix the positioning plate 4, and the device can be used normally. When installing the leaf springs, the leaf springs are placed together in order of different lengths through the connecting shaft. Then, each pair of positioning plates 4 is inserted into the gap between the two leaf springs. If the positioning plate 4 fits the leaf spring perfectly, it means that the leaf spring meets the manufacturing requirements and can continue to be installed and fixed. If the positioning plate 4 cannot be inserted or the gap between the insertion and the leaf spring is too large, it means that the leaf spring is unqualified and needs to be replaced. This design This design makes it easier to detect the leaf spring spacing, eliminating the need for operators to perform single measurements and improving work efficiency. When different models of leaf springs need to be tested, the distance between the positioning plates 4 can be readjusted by removing the bolts 13. At this time, the reset spring 83 resets, causing the fixing plate 7 and the clamping plate 6 to move upward. Then, the distance between the positioning plates 4 can be adjusted according to the above method to test different models of leaf springs. The design of the reset component 8 can prevent the clamping plate 6 from remaining above the sliding positioning component 2 when adjusting the distance between the positioning plates 4, which would cause the adjustment of the positioning plates 4 to have greater resistance and be inconvenient.
