Abstract

The invention discloses a hand-held hydraulic bushing press-mounting device, and belongs to the technical field of machining equipment. A circle of steps is arranged on the outer circumferential surface of the lower end of a steering tool, and the outer circumferential surfaces of the steps are matched with cylinder bottom hinged holes. An internal thread is arranged on the inner circumferential surface of the upper end of the steering tool. A bushing is sleeved on the steering tool, and the lower end of the bushing abuts against on the steps of the lower end of the steering tool. An externalthread matched with the internal thread of the upper end of the steering tool is arranged on the outer circumferential surface of the lower end of a positioning sleeve. A circle of steps is arranged on the outer circumferential surface of the upper end of the positioning sleeve, and the upper end of the bushing abuts against the lower end faces of the steps of the upper end of the positioning sleeve. The diameter of the steps of the positioning sleeve is larger than that of the cylinder bottom hinged holes. A outer seam allowance matched with the upper end of the positioning sleeve is formed in one end of a cylinder cover of a hydraulic oil cylinder. The piston rod end of the hydraulic oil cylinder is detachably connected with a quick-change sleeve with the diameter larger than the diameter of the cylinder bottom hinged holes. The hand-held hydraulic bushing press-mounting device has a compact and portable structure and can be lifted by hand. By adopting the quick-change structure, thehand-held hydraulic bushing press-mounting device is simple in operation and can be suitable for press-mounting of large workpiece bushings. For different specifications, only the tool needs to be replaced.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a hand-held hydraulic bush pressing device. Background technique [0002] Bushing press-fitting machine is a kind of widely used equipment. It mainly consists of structural parts, hydraulic cylinders and hydraulic systems. Bushing press-fitting usually lifts the parts that need to be press-fitted bushings to the press. In the special tooling The press-fitting of the bushing can be completed with cooperation; but due to the limitation of working pressure, stroke and space, it is difficult to complete the press-fitting of the bushing of large parts. [0003] A kind of bush press-fitting machine (CN103894779A) announced as Chinese patent, it is the press-fit machine that gathers power all over the body, is suitable for the bushing press-fitting of small parts in batches, is not suitable for the bushing press-fitting of large workpiece. Another example is a b...
