Description
Technical Field
The utility model relates to an auxiliary device for installing a piston ring by a spring, and belongs to the technical field of part assembly.
Background
In general, a piston ring is installed in an outer diameter groove of a spring support of an assembly formed by two parts assembled by clearance fit of inner and outer diameters, and the piston ring mainly plays a role in sealing. The piston ring belongs to a non-fully closed circular clamping ring, and has certain elasticity and expansion after being arranged in the outer diameter groove. When the spring support assembly of one part is installed on the inner diameter of the other part, the piston ring is required to be compressed first and then guided into the outer diameter groove of the spring support, and then the two parts are assembled in a clearance fit mode.
The traditional mode of assembling the compression spring support piston ring is to carry out manual auxiliary compression by purely manual auxiliary compression or by using a pointed thin cone rod to extend into a spring support gap. The mode can not extend into the gap of the bullet to completely compress the piston ring, and the surface of the bullet and/or the piston ring is easily scratched, and the piston ring is damaged by pressure loss.
Therefore, there is a need for a device that can extend into the small gap of the projectile without scratching the parts and that assists in guiding the fully compressed piston ring.
Disclosure of Invention
In order to solve the problems in the background technology, the utility model provides an auxiliary device for installing a piston ring on a bullet.
The utility model adopts the following technical scheme: the auxiliary device for installing the piston ring of the spring support comprises a support rod and two installation mechanisms, wherein the two installation mechanisms are respectively arranged at two ends of the support rod; each mounting mechanism comprises a pressing plate, a pull rod, a fulcrum shaft, a nut and a supporting block; the inner end of the supporting block is fixedly inserted with the corresponding end of the supporting rod, the supporting block is vertically and slidably inserted with the lower end of the supporting shaft, the square hole at the upper end of the supporting shaft is slidably inserted with the square rod of the pull rod, the inner end of the pull rod is screwed with the nut, and the outer end of the pull rod is vertically and fixedly connected with the pressing plate; the two pressing plates of the two mounting mechanisms are different in length.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model has simple structure and convenient operation, and the auxiliary compression piston ring is transmitted by the nut to move, thereby installing the piston ring in the inner diameter groove and the outer diameter groove of the assembly component, and realizing the guide assembly and installation of the auxiliary compression piston ring which can extend into the small gap of the spring support and can not scratch parts. In addition, according to the piston rings at different positions on the compression spring support, the position conversion of compressing the piston rings at different positions can be completed by replacing the pressing plate, so that the compression spring support has certain universality.
