Tool suitable for disassembly and assembly of traction pin hole inner sleeves of various bogies

Abstract

The invention discloses a tool suitable for disassembling and assembling traction pin hole inner sleeves of various bogies. The tool is composed of a working screw, a push rod, a spiral inner sleeve, a supporting base, a punch, a handrail, a vehicle body, universal wheels, an adjustable baffle and a fastening nut. The screw head part of the working screw is provided with through holes which are in clearance fit with the push rod, and the screw part is in threaded connection with the spiral inner sleeve and the punch and can move up and down relative to the horizontal base plane; and the adjustable baffle is inserted into the moving groove of the vehicle body and is restrained in the horizontal direction by the pre-tightening force of the fastening nut. When the pin hole inner sleeve is detached, the adjustable baffle is adjusted to the position where the pin hole inner sleeve can leak from the position between the two baffles. When the push rod is pushed, the punch downwards acts on the through hole of the pin hole inner sleeve to eject the pin hole inner sleeve out. When the pin hole inner sleeve is installed, the punch acts on the end portion to press the pin hole inner sleeve into the pin hole inner sleeve. The device is simple in structure, convenient to manufacture and install, labor-saving to assemble and disassemble and small in damage to a hole part; the whole device is movable, and field operation is facilitated; the device can be suitable for disassembling and assembling pin hole inner sleeves of bogie traction devices of different vehicle types.

Description

technical field [0001] The invention relates to the technical field of assembly and disassembly tooling for bogie parts, in particular to a tooling suitable for the disassembly and assembly of inner sleeves in traction pin holes of multi-type bogie frames. Background technique [0002] At present, there is no special disassembly and assembly equipment for the installation and removal of the pin hole inner sleeve of the bogie traction device in the vehicle maintenance work, and it is all disassembled by manual hammering. The labor intensity is high, the work efficiency is low, and the hole is easy to be damaged during the disassembly process, which poses a safety risk to the vehicle. [0003] In the existing disassembly and assembly equipment for pin hole inner sleeves, the hydraulic system is complicated, the manufacturing cost is high, an additional power supply is required, it is not movable, the field adaptability is poor, and it cannot adapt to the disassembly and assemb...
