Description

Technical Field

[0001] This utility model belongs to the field of spring processing technology, and specifically relates to a fixing fixture for spring processing. Background Technology

[0002] In modern industrial manufacturing, springs, as a fundamental and crucial mechanical component, are widely used in numerous industries such as automobiles, aerospace, electronic equipment, and machinery. Their quality and performance directly affect the operational stability and reliability of the entire product. With the rapid development of technology in various industries, increasingly stringent requirements are being placed on the precision, specification diversity, and production efficiency of springs.

[0003] Patent application CN202420848050.4 discloses a fixing fixture for spring processing. It uses a limiting component to drive a limiting block to limit and prevent the spring material from falling off. A fixing component rotates a fixed bevel gear. A movable component allows the mounting sleeve, movable block, movable screw, and movable bevel gear to cooperate, so that the mounting plate presses and fixes the spring material. A moving component moves a rack to drive the adjusting rods on multiple adjusting gears to rotate. The adjusting rods also drive the adjusting cam to rotate, which reduces the spring material's rebound during processing and fixes it, thereby improving the performance.

[0004] This spring processing method can only achieve simple clamping function, lacking the ability to accurately position, stably support, and quickly switch between processing different specifications of springs during the spring processing process. Furthermore, when the mounting plate presses the spring together, the spring itself has a certain degree of elasticity, which makes the direction of pressing the spring unpredictable, resulting in inconsistent bending directions of the spring. Consequently, the spring is prone to displacement and twisting due to uneven force during processing, leading to deviations in key dimensions such as the spring pitch and outer diameter, resulting in a low product qualification rate. Moreover, when it is necessary to produce springs of different specifications, it is quite troublesome to replace the matching hollow rod, which requires additional labor costs and affects production efficiency.
