A kind of installation tool suitable for the integral clamp spring of the porcelain cylinder coil

Abstract

The invention discloses a mounting tool suitable for an overall snap spring of a ceramic cylinder coil. The mounting tool comprises a force applying screw rod, a force applying top cap, an upper arm,a support arm, a lower baseplate, a lower top cap, a T-shaped guide rail, a guide groove, a printed board support platform, a guide rod, a screw rod and a fastening screw, wherein the force applying screw rod, the force applying top cap, the upper arm, the support arm, the lower baseplate and the lower top cap form a ceramic cylinder coil pressing device; and the T-shaped guide rail, the guide groove, the printed board support platform, the guide rod, the screw rod and the fastening screw form a printed board fixing device. The force applying screw rod is controlled through a torque to convertto pressure of a coil fixing a snap spring; when flattening of the snap spring is guaranteed, the applied pressure is the lowest, so that the damage problem of a device body is prevented; the horizontal and vertical adjustment of the printed board fixing device is realized through an adjusting nut to adapt to fixation of printed boards with various sizes; the stability of the printed boards in the whole snap spring mounting process is guaranteed; and the welding point stress caused by stress deformation of the printed boards is prevented.

Description

technical field [0001] The invention relates to an installation tool suitable for an integral coil spring of a porcelain vat, which is suitable for the installation of the integral coil spring of various sizes of porcelain vats. Background technique [0002] At present, porcelain cylinder coils are widely used in various aerospace electronic products, especially in various power supply products. Due to the heavy weight of the ceramic cylinder coil itself, it is necessary to install and fix it with an integral circlip to improve the reliability of the installation. During the installation and fixation of the coil, the circlip needs to be flattened so that there is sufficient pre-tightening force. In the past, one person usually uses a pressure piece to flatten the bent circlip on the component surface, while another operator bends the circlip protruding out of the pin on the welding surface and then welds. In the process, two people are required to cooperate with each other, ...

AI Technical Summary

Problems solved by technology

In the past, one person usually uses a pressure piece to flatten the bent circlip on the component surface, while another operator bends the circlip protruding out of the pin on the welding surface and then welds. In the process, two people are required to cooperate with each other, and the operation is difficult. Large, high requirements for personnel skills, it is easy to cause the printed board to be warped by force, and then the solder joints on the printed board are stressed, and it is easy to cause disturbance of the circlip solder joints, cracking of the porcelain cylinder, etc.
