Special tool for simultaneous press fitting of checks rings on two sides of electromagnetic valve energy accumulator

Abstract

The invention discloses a special tool for simultaneous press fitting of checks rings on two sides of an electromagnetic valve energy accumulator. A main valve body is arranged in the center of a bottom plate, and the main valve body is tightly clamped among three limiting blocks; a positioning sleeve mounting plate is horizontally arranged above the bottom plate through a lower linear bearing andmoves up and down, and a tool mounting plate is horizontally arranged above the positioning sleeve mounting plate through an upper linear bearing and moves up and down; the positioning sleeve mounting plate is provided with two through holes which are provided with positioning sleeves; press fitting cutters are fixed to the bottom face of a cutter mounting plate and located above the two positioning sleeves, and each press fitting cutter is provided with a clamping jaw and a plug cover positioning core; a conical surface is machined on the upper hole wall of each positioning sleeve, and the check rings are arranged at the conical surfaces in advance; a magnet is installed at the lower end of each plug cover positioning core, and plug covers are located in the lower ends of the positioningsleeves. By means of the special tool, simultaneous press fitting of the checks rings on the two sides of the electromagnetic valve energy accumulator can be achieved, the effective assembly processis achieved under the conditions that the diameter of the check rings is large, the check rings are not easy to compress and the plug covers need to be assembled together, and the assembling efficiency is greatly improved.

Description

technical field [0001] The invention relates to a special tool for installing an electromagnetic valve accumulator, in particular to a special tool for simultaneous press-fitting of retaining rings on both sides of an electromagnetic valve accumulator. Background technique [0002] The cap of the accumulator of the solenoid valve is fixed in the valve body with an open retaining ring. During the press-fitting process, the cap of the accumulator needs to be pressed into the hole of the valve body, and the open retaining ring is snapped into the groove of the main valve body. Compress the diameter of the retaining ring so that it can pass through the accumulator hole and push it out into the groove of the main valve body. The diameter of the retaining ring is large, so it is not easy to use tools to compress it, and it is difficult to assemble. In order to solve the above problems, it is necessary to design a reasonable structure for press-fitting retaining rings. At the same ...
