Description

Technical Field

[0001] This utility model relates to the field of fixture design technology, and in particular to a fixture for assembling automotive copper brackets with a buffer and shock absorption structure. Background Technology

[0002] In the field of automotive brass bracket assembly, fixtures are core tools for ensuring assembly accuracy and operational safety. With the increasing automation and refinement of automotive component assembly processes, higher demands are placed on fixtures' rapid clamping capabilities, part drop protection performance, and specification adaptability. Traditional assembly fixtures mostly employ fixed clamping modes and rigid support structures, which cannot meet the efficient positioning needs of vehicle frames of different sizes, nor do they have a buffer protection mechanism for parts falling during assembly, easily leading to problems such as part damage, low assembly efficiency, and a cluttered working environment. Therefore, developing a new type of fixture with adaptive clamping and intelligent buffering functions has become crucial for improving the assembly quality and efficiency of automotive brass brackets.

[0003] Existing automotive copper bracket assembly fixtures suffer from three main technical bottlenecks: First, the clamping structure is cumbersome to operate. Traditional manual screw adjustment requires tightening bolts sequentially to fix the frame, resulting in time-consuming clamping and difficulty in ensuring uniform clamping force. This can lead to misalignment of assembly holes due to frame displacement or uneven force. Second, there is a lack of a part drop buffer mechanism. When parts accidentally fall, they directly impact the fixture base plate or the ground, easily causing surface damage, structural deformation, and other injuries. Furthermore, manual collection of scattered parts increases the frequency of work interruptions. Third, the buffer components have poor versatility. Fixed-type shock absorption devices cannot flexibly adjust the buffering force according to the weight of the parts. Over-buffering of small parts may reduce collection efficiency, while insufficient buffering of heavy parts may cause breakage of the parts or damage to the fixture structure. The problems of inefficient clamping, lack of protection, and insufficient buffer adaptability in existing technologies urgently need to be addressed through structural innovations such as bidirectional screw linkage clamping, torsion spring elastic buffering, and adjustable spring components. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a clamping fixture for assembling automotive copper brackets with a buffer and shock absorption structure. This fixture aims to solve the problems of inefficient clamping, easy damage from falling parts, and poor buffer compatibility in existing automotive copper bracket assembly fixtures.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A clamp for assembling a copper bracket for automobiles with a buffer and shock absorption structure includes a base plate, a mounting plate fixedly connected to the top side of the base plate, and multiple connecting pieces fixedly connected to the top side of the base plate. Two connecting pieces at the left end are fixedly connected by a sliding rod. A through groove is formed at the middle of the top side of the mounting plate, and an inlet groove is formed at the left end of the bottom side of the through groove. A collection box is provided on the top side of the base plate. A shock absorption component is provided at the top of the through groove, and an abutment component is provided at the bottom of the inner wall of the through groove. Handles are rotatably connected to both the front and rear sides of the collection box. A motor is installed at the right end of the top side of the mounting plate. A bidirectional screw is fixedly connected to the drive end of the motor. The front side of the bidirectional screw is rotatably connected to the rear side of the connecting piece at the right end. Slide plates are fitted on both the front and rear ends of the outer wall of the bidirectional screw. The left end of the slide plate is slidably connected to the outer wall of the sliding rod. Clamping molds are fixedly connected to the adjacent sides of the two slide plates.

[0007] Furthermore, the damping assembly includes a damping ramp, the left end of which is connected to the left side of the inner wall of the through groove via a torsion spring.

[0008] Furthermore, mounting frames are fixedly connected to both the left and right ends of the bottom side of the mounting plate, and mounting strips are fixedly connected to both the left and right ends of the collection box, with the mounting strips located inside the mounting frames.

[0009] Furthermore, the abutment component includes a fixing plate, and a sliding groove is provided at the right end of the top side of the fixing plate, and the abutment plate is slidably connected inside the sliding groove.

[0010] Furthermore, the front and rear sides of the abutment plate are provided with limiting grooves, and the front and rear sides of the sliding grooves are fixedly connected with limiting slide bars, which are slidably connected inside the limiting grooves.

[0011] Furthermore, the sliding groove is provided with multiple springs, one end of which is connected to the left side of the sliding groove and the other end is connected to the left side of the abutment plate.

[0012] Furthermore, the spring is internally provided with a telescopic rod, one end of which is connected to the left side of the sliding groove, and the other end is connected to the left side of the abutment plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, when a part falls onto the shock-absorbing ramp during assembly, the torsion spring absorbs the impact force through elastic deformation, causing the shock-absorbing ramp to tilt and guide the part into the collection box, reducing vibration and damage when the part lands. This structure utilizes the buffering characteristics of the torsion spring to effectively reduce the risk of damage to parts caused by collisions and improve the safety of the assembly process.

[0015] 2. In this utility model, collection boxes equipped with springs of different elastic coefficients can be installed according to the weight and characteristics of different parts. For light and small parts, low-stiffness springs are used to achieve flexible buffering; for heavier parts, high-stiffness springs are replaced with rigid support from the abutment plate to prevent overload failure of the torsion spring. This design, through adjustable spring assemblies, achieves precise buffering protection for parts of different specifications, significantly improving the versatility and operational adaptability of the fixture.

The left end of the slide plate 7 is slidably connected to the outer wall of the sliding rod 3. The clamping plate mold 5 is fixedly connected to the adjacent side of the plate 12. The left end of the shock-absorbing inclined plate 12 is connected to the left side of the inner wall of the through groove 9 through the torsion spring 16. The left and right ends of the bottom side of the mounting plate 4 are fixedly connected to the mounting frame 15. The left and right ends of the collection box 11 are fixedly connected to the mounting strip 13. The mounting strip 13 is located inside the mounting frame 15. The right end of the top side of the fixed plate 14 is provided with a sliding groove. The sliding groove is slidably connected to the abutment plate 17. The front and rear sides of the abutment plate 17 are provided with limit sliding grooves 19. The front and rear sides of the sliding groove are fixedly connected to limit sliding strips 18. The limit sliding strips 18 are slidably connected inside the limit sliding grooves 19. The sliding groove is provided with multiple springs 20. One end of the spring 20 is connected to the left side of the sliding groove and the other end is connected to the left side of the abutment plate 17. The spring 20 is provided with a telescopic rod 21. One end of the telescopic rod 21 is connected to the left side of the sliding groove and the other end is connected to the left side of the abutment plate 17.

[0024] Specifically, when using this automotive copper bracket assembly fixture with a shock-absorbing structure, the operation process revolves around stable clamping and part cushioning. First, the vehicle frame to be assembled is placed between the two clamping molds 5 at both ends. The motor 6 is started to drive the bidirectional screw 8 to rotate, causing the sliding plate 7 and clamping molds 5 to move towards each other, achieving precise fixing and rapid clamping of the frame. During assembly, if a part falls onto the top side of the shock-absorbing ramp 12, its weight will disrupt the initial balance of the torsion spring 16, causing the ramp to tilt and guide the part into the collection box 11. This design absorbs the impact force of the falling part through the elastic deformation of the torsion spring 16, reducing the risk of vibration and damage upon landing. Simultaneously, the right end of the top side of the abutment plate 17 abuts against the bottom side of the shock-absorbing ramp 12, providing rigid support when the part weight exceeds the cushioning range of the torsion spring 16, preventing cushioning failure. Furthermore, the collection box 11 is connected to the base plate 1 via spring 20 and telescopic rod 21. Springs 20 with different elastic coefficients can be replaced according to the part weight to adapt to diverse cushioning needs. This fixture, through the linkage clamping of the bidirectional screw 8 and the buffer structure of the torsion spring 16 and the shock-absorbing inclined plate 12, not only ensures the stability of the frame assembly, but also performs graded buffering and collection of fallen parts, thereby improving assembly safety and work efficiency.

[0025] Working principle: In use, the frame to be assembled is first placed between the two clamping plate molds 5. Then, the motor 6 is started to drive the bidirectional screw 8 to rotate, which in turn moves the two sliding plates 7 and the clamping plate molds 5 towards the middle, thereby fixing the frame. Then the frame can be assembled. During the assembly process, if any assembled parts fall, they will fall to the top side of the shock-absorbing ramp 12, increasing the overall force on the shock-absorbing ramp 12. This causes the torsion spring 16 to be unable to maintain the original angle of the shock-absorbing ramp 12, resulting in tilting. This causes the parts to fall into the collection box 11, reducing the force on the parts when they fall and reducing the possibility of vibration and damage when the parts land. At the same time, the right end of the top side of the abutment plate 17 abuts against the bottom side of the shock-absorbing ramp 12, which can prevent the shock-absorbing ramp 12 from being ineffective due to the weight of the parts. At the same time, collection boxes 11 with different springs 20 can be installed according to different parts.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
