Description
Technical field:
The utility model relates to a kind of dismantling device of shaft type axial plunger pump cylinder body spring.
Background technology:
When repairing the shaft type axial plunger pump, dismounting cylinder body spring is a relatively stubborn problem.The elastic force of compression spring is stronger, split out this spring, should earlier pad be pushed in to the right, with Circlip tongs the hole is split out with back-up ring then pad is slowly withdrawed from, and spring both can split out.During mounting spring, with opposite program.This spring of dismounting at present needs two people compounding practice on bench vice.This assembly and disassembly methods is not only required great effort but also inconvenient, also dangerous.
Summary of the invention:
The purpose of this utility model just provides a kind of cylinder body spring dismantling device, and this instrument one man operation can safe ready ground remove and install the cylinder body spring.
To achieve these goals, the utility model adopts following technical scheme:
The utility model comprises pull bar, and an end of pull bar is provided with pull head, the nuts and washers that the other end is provided with thread head and matches and use.
The utlity model has characteristics such as simple in structure, easy to use.
