Problems solved by technology

[0003] During the production of the jack, the piston rod needs to be introduced into the cylinder body. The existing way of introduction is generally manually assembled by the staff, and the efficiency is low. Although the assembly efficiency of the general machine introduction device is high, the axis of the cylinder body is easy to contact with the piston. The misalignment of the rod leads to the failure of assembly, and the piston rod is prone to rigid friction with the inner wall of the cylinder when it is introduced, which in turn scratches the piston rod and affects the precision of the piston rod. Therefore, we propose a convenient combination installation device for jacks

Abstract

The invention relates to the technical field of jacks, and discloses jack convenient combination and installation equipment which comprises a base, a fixing table and two supporting rods are welded to the top of the base, a fixing plate is slidably connected between the two supporting rods, a clamping plate is welded to the tops of the two fixing plates, and an air cylinder is always arranged above the clamping plate; a lubricating mechanism is welded to the bottoms of the two fixing plates, and an accurate shaft mechanism is arranged in the fixing table. The piston rod penetrates through the center of the movable disc, makes contact with the lubricating ball plug and extrudes the lubricating ball plug in the opposite direction to open the oil outlet pipe, and at the moment, the extruded lubricating oil in the feeding cavity is sprayed to the piston rod from the oil outlet pipe, so that the friction force on the side face of the piston rod is reduced; therefore, the effect of preventing rigid friction between the piston rod and the cylinder body when the piston rod is guided into the cylinder body is achieved, the piston rod is prevented from being scratched, and the quality of the assembled jack is improved.

Description

technical field [0001] The invention relates to the technical field of jacks, in particular to a convenient combined installation device for jacks. Background technique [0002] The jack is a light and small lifting device that uses a rigid jacking piece as a working device to lift heavy objects through a small stroke of the top bracket or the bottom claw. The jack is mainly used in factories, mines, transportation and other departments as vehicle repair and other Lifting, supporting and other work, the structure of the jack is light, strong, flexible and reliable, and can be carried and operated by one person. [0003] When the jack is produced, the piston rod needs to be introduced into the cylinder. The existing introduction method is generally manual assembly by the staff, which is inefficient. The general machine introduction device has high assembly efficiency, but the axis of the cylinder is easy to connect with the piston. The rod is misaligned, which leads to the f...
