Problems solved by technology
However, two stretching mechanisms are used at both ends, which will lead to inconsistent stretching ratios at both ends of the spring, and the center of the spring will shift
[0003] If the above problems occur, the overall material of the spring used is uneven, which will directly lead to inaccurate elastic coefficients. Under the premise of different deformations, the elastic coefficient of the spring is unstable.
For precision instruments, if the elastic performance of the spring itself is unstable, it will directly lead to unstable performance of the instrument.

The invention discloses a spring machining workpiece, and particularly relates to a spring length fixing machine which comprises a rack and positioning blocks arranged on the rack and used for fixing the left end and the right end of a spring respectively. An abutting block is arranged at the upper end of each positioning block and arranged above the spring, a wedge-shaped block is arranged above the abutting blocks, each of the surfaces, facing the abutting blocks, of the wedge-shaped block is a bevel, the two bevels are symmetrically distributed along a perpendicular bisector of a connecting line between the positioning blocks, an included angle portion is arranged at a position where the bevels are connected and arranged at the lower end of the wedge-shaped block, the wedge-shaped block is connected with a hydraulic rod through a connecting rod, the middle of the connecting rod is hinged on a fixing member, and the positioning blocks are slidably connected on the rack. The defect that a spring is unstable in elasticity in the prior art is overcome, and the spring length fixing machine can uniformly draw the spring.
Description
technical field [0001] The invention relates to a spring processing workpiece, in particular to a spring length fixing machine. Background technique [0002] Most of the existing spring stretching and fixed-length equipment is to sleeve a section of spring on a cylinder, and then use two identical stretching mechanisms at the two ends of the spring to stretch. However, if two stretching mechanisms are used at both ends, the stretching ratios at the two ends of the spring will be inconsistent, and the center of the spring will deviate. [0003] If the above problems occur, the overall material of the spring used will be uneven, which will directly lead to inaccurate elastic coefficients. Under the premise of different deformations, the elastic coefficients of the springs will be unstable. For precision instruments, if the elastic performance of the spring itself is unstable, it will directly lead to unstable performance of the instrument. For example, the Chinese patent CN2...
