Technical scheme: for solving above-mentioned technical problem, a kind of axis hole interference fit mounting or dismounting hydraulic pressure load push-pull with releasing pressure automatically function of the present invention, including the push-and-pull body being connected with hole type parts and the stiff piston being connected with axial workpiece, described push-and-pull body is cylindric, the shoulder hole comprising macropore and aperture it is provided with in load push-pull body, push-and-pull body is provided with the pushing oil filler point connected with shoulder hole, push oil filler point and be positioned at macropore and aperture intersection, push-and-pull body is provided with several and pushes oil leak hole, push oil leak hole to connect with the macropore of push-and-pull body, push oil leak hole and be provided with sealing-plug, described stiff piston is the multidiameter comprising big axle and little axle, described big axle and macropore, is the interference fits with excellent sealing effect between little axle and aperture.
As preferably, described pushing oil leak hole equidistant arrangement, between stiff piston and axial workpiece, it is provided with stroke cushion block, the thickness of stroke cushion block is the distance between adjacent pushing oil leak hole.
As preferably, the end face of the big axle of described stiff piston is connected with dismounting cushion block.
As preferably, described multidiameter comprises the shaft shoulder, and the shaft shoulder is taper seat, and macropore is the taper seat coordinated with the shaft shoulder with the interface of aperture.
Beneficial effect: the axis hole interference fit mounting or dismounting hydraulic pressure load push-pull with releasing pressure automatically function of the present invention, has a little:
(1) high-pressure oil pump is utilized to pass into pushing oil in pushing oil filler point, act on stiff piston, drive stiff piston moves, thus driving axial workpiece to move, when hole type parts arrives cooperation position, the piston end surface of stiff piston reaches to push oil leak hole position just, now, push oil leak hole and outwards export fluid, oil pressure convergence and zero in hydraulic pressure load push-pull, axis hole interference fit connector remains stationary, it is to avoid cross assembling and because axially pushing the secondary assembly problem that distance deficiency carries out because of what axially push that distance too much causes;
(2) with, in the interference fit process of taper shaft hole type parts, utilizing pushing oil leak hole on push-and-pull body to make part remain stationary, it is prevented that because axis hole conical surface counteracting force makes part occur automatically to skid off phenomenon;
(3) different pushing oil leak hole and supporting stroke cushion block or dismounting cushion block are selected, it may be achieved the installation of the axis hole interference fit of various advance distances and dismounting.

Detailed description of the invention
As shown in Figures 1 to 6, a kind of axis hole interference fit mounting or dismounting hydraulic pressure load push-pull with releasing pressure automatically function of the present invention, including the push-and-pull body 1 being connected with hole type parts 6 and the stiff piston 2 being connected with axial workpiece 7, described push-and-pull body 1 is cylindric, the shoulder hole comprising macropore and aperture it is provided with in push-and-pull body 1, push-and-pull body 1 is provided with the pushing oil filler point 3 connected with shoulder hole, push oil filler point 3 and be positioned at macropore and aperture intersection, push-and-pull body 1 is provided with several and pushes oil leak hole 4, push oil leak hole 4 to connect with the macropore of push-and-pull body 1, push oil leak hole 4 and be provided with sealing-plug, sealing-plug can be bolt or stopper, described stiff piston 2 is the multidiameter comprising big axle and little axle, described big axle is the interference fits with excellent sealing effect with macropore, little axle with aperture, multidiameter comprises the shaft shoulder, the shaft shoulder is taper seat, macropore is the taper seat coordinated with the shaft shoulder with the interface of aperture, hydraulic oil acts on taper seat, is more conducive to startup and the movement of stiff piston 2.
In the present invention, described pushing oil leak hole 4 equidistant arrangement, between stiff piston 2 and axial workpiece 7, it is provided with stroke cushion block 8, the thickness of stroke cushion block 8 is the distance between adjacent pushing oil leak hole 4, and stroke cushion block 8 is discoid, is provided with multiple installing hole.
