Description

Technical Field

[0001] This utility model relates to the field of automotive spring processing technology, and in particular to a spring fixing device for automotive spring processing. Background Technology

[0002] In the automotive spring manufacturing industry, traditional spring fixing devices mostly adopt single-sided clamping or simple mechanical limiting designs. For example, some equipment relies on a single cylinder to drive the clamping plate, applying pressure to the spring from one side to complete the fixing. The limitation of this fixing method is that, during processing such as grinding and welding, the spring is prone to displacement due to uneven force due to the lack of all-round constraint, which in turn leads to dimensional deviations and significantly increases the scrap rate.

[0003] To improve the instability of unilateral fixing, a multi-jaw spring fixing fixture has been introduced. This fixture uses multiple circumferentially distributed jaws, which achieve synchronous tightening through a gear transmission mechanism to fix the spring. Compared with unilateral clamping, this multi-jaw synchronous action significantly enhances the stability of spring fixing and effectively reduces misalignment during processing.

[0004] However, while multi-jaw spring clamps solve the original technical problems, the opening and closing range of the clamp jaws is fixed, making it difficult to adapt to springs of different diameters and heights, resulting in insufficient equipment versatility. Secondly, the jaw material has a high hardness, which can easily scratch the surface when clamping springs, affecting product quality and increasing the cost and time consumption of subsequent repair processes.

[0025] Working Principle: When using this automotive spring processing spring fixing device, first place the automotive spring vertically in the middle of the workbench 2, so that the spring is sleeved on the outside of the first fixing rod 308 and the second fixing rod 310. At this time, the operator starts the first motor 302 through the control panel 9 at the front end of the support box 1. The first motor 302 starts to work, and its front transmission end drives the first rotating shaft 303 to rotate. Since the first thread 304 on the rear side of the first rotating shaft 303 and the second thread 305 on the front side have opposite directions of rotation, and the threads inside the first slider 307 are adapted to the first thread 304, and the threads inside the second slider 309 are adapted to the second thread 304, the first thread 304 on the rear side of the first rotating shaft 303 has opposite directions of rotation. 5. Adaptation: When the first rotating shaft 303 rotates, the first slider 307 and the second slider 309 will move in opposite directions or in the opposite direction along the axial direction of the first rotating shaft 303, according to the principle of threaded transmission. The first slider 307 drives the first fixed rod 308, and the second slider 309 drives the second fixed rod 310, synchronously moving towards or away from the spring. Utilizing the friction between the rubber sleeves on the outer sides of the first fixed rod 308 and the second fixed rod 310 and the spring, initial fixation is achieved from the front-back direction of the spring. Furthermore, the distance between the two fixed rods can be flexibly adjusted according to the length of the spring to accommodate springs of different lengths, completing the front-back... After the initial fixation in the directional direction, the fixation operation in the left and right directions is then carried out. The operator controls the electric push rod 403 again through the control panel 9. The transmission end of the lower end of the electric push rod 403 pushes the connecting block 404 downward, so that the third fixing rod 412 and the fourth fixing rod 414 inside the connecting block 404 extend into the inside of the spring and reach the appropriate height position. Then, the second motor 406 is started. The transmission end of the right end of the second motor 406 drives the second rotating shaft 407 to rotate. Also based on the thread transmission principle, the third thread 408 on the left side of the second rotating shaft 407 is adapted to the thread inside the third slider 411, and the fourth thread 408 on the right side is adapted to the thread inside the third slider 411. 9 is adapted to the internal thread of the fourth slider 413, and the third thread 408 and the fourth thread 409 rotate in opposite directions. During the rotation of the second rotating shaft 407, the third slider 411 and the fourth slider 413 will drive the third fixing rod 412 and the fourth fixing rod 414 to move towards the middle synchronously on the inside of the spring. Using the rubber sleeves on the outside of the third fixing rod 412 and the fourth fixing rod 414, the spring is clamped and fixed from the left and right directions. In this way, through the coordinated cooperation of the front and rear fixing components 3 and the left and right fixing components 4, the multi-angle, three-dimensional and firm fixation of the car spring is achieved, which can effectively prevent the spring from shifting or shaking during the processing.
