Embodiment Construction

[0024] Examples of spring assembly tooling such as Figure 2-3 As shown, the tooling includes a push cylinder 101 and a guide body 102. The push cylinder 101 is spliced ​​by multiple (more than two) push blocks 11, and the outer peripheral surface of each push block 11 is along the axial direction of the push cylinder. There are two grooves, and the grooves on each push block 11 are correspondingly connected together to form a limit groove, and an elastic tightening ring 12 is arranged in the limit groove, and the elastic tightening ring 12 tightens each push block 11 Together, the cross section of each push block 11 is in the shape of a truncated fan, and one end of each push block 11 used to push the spring coil to be assembled forms an expansion and contraction opening, and the expansion and contraction opening is not larger than the spring coil to be assembled 13 inner diameter. As far as this embodiment is concerned, the upper end of the guide body 102 has a cylindrical ...

Abstract

The invention relates to the field of mechanical assembly, in particular to a spring ring assembly fixture and spring ring installation equipment using the same. The spring ring assembly fixture comprises a pushing cylinder and a guide body, wherein the pushing cylinder is formed by splicing more than two pushing blocks; one end, used for pushing a to-be-assembled spring ring, of each pushing block is encircled into a swelling-shrinkage hole; the swelling-shrinkage hole is not greater than the inner diameter of the to-be-assembled spring ring. As the pushing cylinder of the spring ring assembly fixture is formed by splicing more than two pushing blocks, moreover, one end, used for pushing a to-be-assembled spring ring, of each pushing block is encircled into the swelling-shrinkage hole, and the swelling-shrinkage hole is not greater than the inner diameter of the to-be-assembled spring ring, when press fitting is performed on the spring ring, the pushing cylinder can be kept fitted with the guide body all along, and therefore a gap between the pushing cylinder and the guide body is eliminated, and the spring ring is prevented from being crushed, thus, the problem that the spring ring can be easily clamped by the traditional spring ring installer is solved by the spring ring assembly fixture disclosed by the invention.

Description

technical field [0001] The invention relates to the field of mechanical assembly, in particular to a spring coil assembly tool and spring coil installation equipment using the tool. Background technique [0002] In the field of mechanical assembly, it is often encountered that spring coils need to be installed on shafts and sleeves. In the prior art, when installing the helical spring coils, the diameter of the coils is generally enlarged by hand pliers, then inserted into the mounting grooves of the corresponding shaft parts, and finally tightened. In this way, it is easy to cause plastic deformation of the spring coil after expansion, and the shape cannot be completely restored. In addition, when the pliers are stretching the spring coil, the spring coil tends to be partially deformed due to uneven force, which will directly reduce the spring coil. service life. [0003] From the above description, it can be seen that there are many disadvantages in the way of installing...
