In order to solve the problems existing in the technical background, the invention provides a plunger master cylinder cup assembling tool, which can realize easy assembly of a plunger master cylinder cup, and solves the problems that the cup groove cannot be directly contacted and the eyes cannot be directly checked because the cylinder hole is too deep, the cup is difficult to assemble, the cup is easy to scratch in the assembling process, and the batch loading requirement state of the plunger master cylinder cannot be met in the existing plunger master cylinder, and the batch production and use requirements are met.
In order to solve the technical problems, the invention adopts the following technical scheme:
utilize plunger master cylinder leather cup assembly fixture
The leather cup comprises a support column and a mandrel, wherein a through hole is formed in the center of the support column, the mandrel is installed in the through hole, one end of the support column is processed into a semi-cylindrical structure, a semi-circular strip-shaped groove is formed in the center of the outer side surface of the plane of the semi-cylindrical structure and communicated with the through hole, semi-circular ring grooves arranged along the circumferential direction are formed in the outer side surface of a semi-cylindrical surface in the middle of the semi-cylindrical structure, a leather cup is sleeved in the semi-circular ring grooves of the semi-cylindrical structure of the support column, and the leather.
The through hole arranged in the center of the support column is in clearance fit with the mandrel.
The end part of the mandrel extending into the through hole is spherical.
The leather cup is of an annular elastic structure.
Second, assembling method of assembling tool by using plunger main cylinder leather cup
During the assembling process, the tool provided by the invention carries the leather cup to be arranged in the cylinder body of the plunger main cylinder, then the mandrel is pulled out, and the leather cup automatically pops into the corresponding leather cup groove of the cylinder body by utilizing the elasticity of the leather cup.
And the leather cup positioned on the outer side surface of the plane of the semi-cylindrical structure is pressed into the semicircular strip-shaped groove after the mandrel penetrates through the through hole.
The invention has the beneficial effects that:
the invention solves the problems that the existing plunger master cylinder leather cup is difficult to assemble and easy to scratch and cannot completely meet the actual use state of the plunger master cylinder, and the offline qualification rate of the plunger master cylinder assembly is improved to 100 percent.
