Description

Technical Field

[0001] This utility model relates to the field of leaf spring assembly pressing, specifically a special stand for rapid pressing of leaf spring assemblies. Background Technology

[0002] As the core elastic element of automotive suspension, leaf springs are composed of multiple alloy spring plates of unequal length. Their assembly quality directly affects the stability and safety of the vehicle. Since each spring plate is elastic and there are gaps between them, external force must be used to tightly press the spring plates during assembly or replacement to ensure that the bolts and nuts are accurately aligned and effectively tightened.

[0003] Currently, the standardized assembly of leaf spring assemblies mainly relies on specialized benches in production workshops. While these benches can meet the batch assembly needs within the workshop, they have significant limitations in application scenarios. In vehicle repair and parts replacement at the OEM site, or in temporary assembly operations outside of specialized leaf spring assembly workshops, there is often a lack of suitable clamping tools. In such cases, operators need to manually overcome the elastic tension of the spring plates, attempt to align the bolt holes, and tighten them. However, the rebound force of the spring plates causes the gaps between the plates to recur, making it difficult to tighten the bolts and nuts smoothly. Uneven force may also cause problems such as stripped threads and broken bolts. In severe cases, assembly or replacement may not be completed, affecting the vehicle repair progress.

[0004] In addition, most of the existing workshop-specific stands are fixed structures, which are large in size and inconvenient to move, and cannot meet the needs of mobile operation scenarios such as OEM sites and maintenance stations. Even if simple tools (such as jacks and pry bars) are used to temporarily assist in tightening, it is difficult to accurately control the tightening force. If the pressure is too small, there will still be gaps in the spring sheet, and if the pressure is too large, the spring sheet may be deformed and damaged. Moreover, it is difficult for a single person to simultaneously tighten and fasten the bolts, which further reduces assembly efficiency and reliability.

[0005] The lack of specialized clamping tools in non-professional settings has become a key issue hindering on-site replacement and emergency assembly of leaf spring assemblies. This not only increases labor costs and operational difficulty but may also create safety hazards due to improper assembly. Therefore, there is an urgent need for a specialized stand that can quickly clamp leaf spring assemblies in non-leaf spring assembly workshop settings. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please refer to Figure 1-4 As shown, this utility model provides a special stand for quick pressing of leaf spring assembly, including an operating table 1, a bracket 2 welded to the top of the operating table 1, a pressing component for fixing the leaf spring installed on the top of the bracket 2, two fixing grooves 3 opened on the top of the operating table 1, an adjusting component for adjusting the width of the support frame 4 installed inside the fixing grooves 3, a locking component installed between the support frame 4 and the adjusting component, the locking component is used to adjust the tilt angle of the support frame 4, and a placement groove 20 for placing the grip 7 is opened on the top of the operating table 1.

[0025] Additionally, the grip 7 has an anti-slip sleeve on its outer side to prevent it from sliding. The placement slot 20 can store and place the grip 7. The bracket 2 has an L-shaped cross-section. The clamping member at the top of the bracket 2 moves up and down, pressing down on the workpiece placed on the top of the operating table 1. The adjusting member can move the two support frames 4 closer or further apart. The support frame 4 changes angle at the top of the adjusting member. The locking member can lock and fix the tilt angle of the support frame 4 so that the support frame 4 can adapt to the workpiece for support and limitation, thereby limiting and fixing the workpiece in multiple directions.

[0026] Specifically, the clamping component includes a screw 5 that passes through the top of the bracket 2, a nut ring 6 welded to the top of the screw 5, a handle 7 threaded through the inner side of the nut ring 6, a pressure plate 9 fitted at the bottom of the screw 5 via a fixing part 8, and the handle 7 can be screwed and disassembled with the nut ring 6. A gasket 17 is laid on the surface of the operating table 1 between the two fixing grooves 3, an anti-slip pad 18 is laid at the bottom of the pressure plate 9, and a guide block 19 is fixedly connected to one side of the pressure plate 9. The guide block 19 is embedded in one side of the bracket 2 and slidably connected to it.

[0027] Among them, the gasket 17 can support the bottom of the workpiece, and the anti-slip pad 18 at the bottom of the pressure plate 9 can fit with the surface of the workpiece, increasing the stability of fixing the workpiece and the protection effect of scratch and wear resistance. The end of the handle 7 is fixed and disassembled by the threaded part and the nut ring 6. The handle 7 can drive the screw 5 to rotate through the nut ring 6, so that the fixing part 8 at the bottom of the screw 5 drives the pressure plate 9 to move downward. The guide block 19 can guide and limit the pressure plate 9 to prevent the pressure plate 9 from shifting or shaking. The leaf spring to be replaced is placed on the two support frames 4 on the top of the operating table 1. The leaf spring assembly is pressed by rotating the screw 5 through the handle 7. When individual steel plates, pads, or bolts are replaced, the handle 7 drives the pressure plate 9 to move upward through the bolts. After the replacement is completed, the fastening bolts are tightened to finally complete the replacement and assembly of the leaf spring assembly.

[0028] More specifically, the adjusting component includes a bidirectional lead screw 10 that passes through the inner side of the fixed groove 3. A handle 11 is fixedly installed at one end of the bidirectional lead screw 10. Two moving blocks 12 are fitted on the outer side of the bidirectional lead screw 10. The bidirectional lead screw 10 passes through the moving blocks 12 and is screwed to them. The moving blocks 12 are slidably connected to the fixed groove 3.

[0029] In addition, the handle 11 can drive the bidirectional lead screw 10 to rotate, and the bidirectional lead screw 10 can drive the two moving blocks 12 to slide in the fixed groove 3, so that the two moving blocks 12 move closer or further away from each other, thereby improving the convenience of the moving blocks 12 driving the support frame 4 to move.

[0030] Furthermore, the adjusting component also includes a fixing post 13 fixedly connected to the top of the moving block 12, a groove 14 at the bottom of the support frame 4, a star bolt 15 threaded through and screwed onto one side of the support frame 4, and multiple locking slots 16 arranged in a circle on the outer side of the fixing post 13. The fixing post 13 fixedly installed on the top of the moving block 12 fits into the groove 14 at the bottom of the support frame 4, and the star bolt 5 is screwed into the support frame 4 and rotated into the locking slot 16 to increase the tilt angle of the adjustable support frame 4 so that the support frame 4 can adapt to the shape and angle of the workpiece.

[0031] Working principle: First, the handle 11 is used to drive the double-acting screw 10 to rotate. At this time, the double-acting screw 10 drives the two moving blocks 12 to slide in the fixed groove 3. At the same time, the two moving blocks 12 drive the support frame 4 to move closer or further away from each other through the fixed column 13. Then, the support frame 4 on the top of the moving blocks 12 rotates around the fixed column 13. Next, the star screw 5 is rotated so that its end is inserted into the locking groove 16 to lock and fix the support frame 4. Then, the leaf spring is placed on the support frame 4, and the washer 17 is attached to the bottom of the leaf spring. Then, the handle 7 is screwed and fixed to the nut ring 6, so that the screw 5 is driven to rotate through the nut ring 6. At this time, the fixed part 8 at the bottom of the screw 5 drives the pressure plate 9 to move downward. At the same time, the guide block 19 guides and limits the pressure plate 9. Then, the anti-slip pad 18 at the bottom of the pressure plate 9 is attached to the top of the leaf spring.
