Hydraulic jack assembly equipment

Abstract

The invention discloses hydraulic jack assembly equipment. The hydraulic jack assembly equipment comprises a machine frame, a cylinder block positioning seat, a piston positioning seat and a horizontal pushing hydraulic cylinder. The cylinder block positioning seat and the horizontal pushing hydraulic cylinder are separately installed and fixed to the two ends of the machine frame. The piston positioning seat is fixed to a top plate by bolts, and a connecting sleeve is fixed to the center position of the lower surface of the top plate. The connecting sleeve is rotatably connected to the top end of a stud, and a fixing seat is fixed to the bottom of the machine frame by bolts. A worm wheel is rotatably disposed in the fixing seat, and the worm wheel and the stud are connected through threads. The fixing seat is further rotatably connected with a rotating shaft, and the rotating shaft is integrally provided with a worm. By rotating an adjusting wheel, the worm on the rotating shaft is used for driving the worm wheel to rotate, and then the worm wheel drives the stud to drive the top plate to push a piston rod positioning seat to move up and down, so that the height of a piston rod isadjusted, the shaft axes of the piston rod and a cylinder block are coincident, and the hydraulic jack assembly equipment can be used for assembly of jacks of different specifications to improve theassembly speed.

Description

technical field [0001] The invention belongs to the technical field of hydraulic cylinder assembly devices, and in particular relates to hydraulic jack assembly equipment. Background technique [0002] Jack, commonly known as oil cylinder, is one of the common hydraulic components in coal mine machinery and equipment, and is widely used in coal mines. The jack specifically includes a cylinder body and a piston rod. When assembling the jack, it is necessary to guide the piston rod into the cylinder body, and finally fix the piston rod and the cylinder body as a whole through guide sleeves and other accessories. [0003] For example, the patent application number CN201220463566.4 discloses a jack assembly device for assembling a jack to be assembled, the jack to be assembled includes a piston rod and a cylinder, and the jack assembly device includes: hydraulic power equipment for power supply; It is used to guide the piston rod of the jack to be assembled into the power jack...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned scheme has the following defects in use: it can only be assembled with a cylinder body and a piston rod of a specific model size, which is relatively limited in use. Because in actual use, there are various types of jacks, if the cylinder body of the jack to be assembled and the piston rod If the piston rod is too large or too small, the limit part will not be able to accurately position the cylinder body and the piston rod, and the jack assembly will not be completed
