Servo valve body assembling tooling

Abstract

The invention relates to a servo valve body assembling tooling. The servo valve body assembling tooling is characterized in that a left shaft is installed on a support on the left side, a right shaft is installed on a support on the right side and a handle assembly is installed at the outer end of the left shaft; an upper mounting plate is arranged between the supports on the left and right sides, and the left side and the right of the upper mounting plate are respectively and fixedly connected onto the left shaft and the right shaft; the bottom of a turntable is rotatably installed on the upper mounting plate; a four-pin positioning vertical plate and a vertical positioning plate are fixedly arranged on the turntable, positioning pins are installed on the positioning side surfaces of the four-pin positioning vertical plates, a vertical stud is installed at the top of the vertical positioning plate, and a pressing plate is installed on the stud; a splayed positioner is arranged below the upper mounting plate and is fixedly arranged on a main body bottom plate, and a vertical adjustable bumper and a horizontal adjustable bumper are installed on the splayed positioner; a positioning plate is arranged on the rear side of the upper mounting plate and a positioning push pin is installed in a positioning installation hole in the positioning plate through a spring assembly; holes are formed in the periphery of the turntable and positioning taper sleeves are installed in the holes. The servo valve body assembling tooling has the advantages that the angle can be freely adjusted, the tooling is convenient to operate on the whole and the visibility is proper.

Description

technical field [0001] The invention relates to tooling equipment for hydraulic components, in particular to a tooling body for assembling a servo valve body, which is suitable for the technical field of construction machinery equipment assembly. Background technique [0002] The servo valve body is an important part of the P090 variable displacement plunger pump. Due to the reversing performance, pressure loss, internal leakage, reciprocating reversing and reset time, reversing frequency and service life of the plunger pump to the servo valve body, etc. The performance requirements are very high, and the assembly precision requirements are even higher. Originally, when assembling the servo valve body, only a flat-nose pliers was placed on the assembly table for assembly. The servo valve body is small in size, and it often forms arbitrary inversions in the assembly procedure, and no specific assembly specifications can be formed in the system, especially in assembly and disa...

Problems solved by technology

Originally, when assembling the servo valve body, only a flat-nose pliers was placed on the assembly table for assembly. The servo valve body is small in size, and it often forms arbitrary inversions in the assembly procedure, and no specific assembly specifications can be formed in the system, especially in assembly and disassembly. In the repeated process of inspection and debugging, it is easy to cause the parts to lose precision, and the assembly efficiency is low. The "assembly standardization" and "assembly process" of the servo valve body have not been realized, and the requirements of modern production cannot be met.
