Description
Technical Field
The invention belongs to the technical field of tool fixtures, and particularly relates to a spindle bush hoisting device.
Background
When an engine is overhauled, the diesel engine needs to be hung down to be disassembled into all parts, when a main shaft bush and a crankshaft are overhauled, a main shaft bush cover needs to be disassembled and taken out manually, the accidents of falling to the ground and squeezing hands often occur, time and labor are wasted, and the overhauling progress is influenced. In the production process of an engine, a spindle bush is required to be pressed into an arc-shaped groove of a spindle cover through a pressing device, scrap iron can be scraped out due to friction between the spindle bush and the spindle cover in the process, the scrap iron can easily fall into the inner surface of the spindle bush when the scrap iron is manually cleaned, and the scrap iron can cause strain of the spindle bush and a crankshaft journal in the later operation process.
Disclosure of Invention
The invention aims to provide a main shaft bush hoisting device, so that the defect that the main shaft bush and the crankshaft journal are damaged by pulling due to scrap iron generated in the hoisting/press-fitting process in the prior art is overcome, the main shaft bush is conveniently covered from a diesel engine body, the operation is safe, time and labor are saved, and the overhaul progress is improved. To solve the problems set forth in the background art described above.
In order to achieve the purpose, the technical scheme provided by the invention is as follows:
the utility model provides a spindle bush hoist device, includes screw rod, flute profile hanger bracket and tile, flute profile hanger bracket has opening slot down, and the width of opening slot and the interval clearance fit of the both sides face of spindle bush lid are setting up two screw holes that pierce through the cell wall respectively on the cell wall of flute profile hanger bracket symmetry, are installing the screw in the screw, and the tip of screw cooperatees with the horizontal recess on the spindle bush lid side respectively, the screw rod top be provided with rings, bottom and central part fixed connection on the tile, the screw rod passes flute profile hanger bracket center, and its upper portion is provided with the handle collar, install three handle on the handle collar.
Furthermore, the width of the pad is in clearance fit with the space between the two side surfaces of the main shaft pad cover.
Furthermore, cushion blocks are arranged at two ends and the central part of the inner wall of the tile block.
Furthermore, the positions, corresponding to the two edges of the arc-shaped groove of the main shaft tile cover, on the tile block are respectively provided with at least one mounting hole, and a magnet rod is arranged in each mounting hole.
Further, the magnet rod is detachably fixed in the mounting hole.
Further, the cushion block is made of an anti-skid material.
The invention has the beneficial effects that: the magnet rod is additionally arranged on the press mounting block, so that generated scrap iron is cleaned in time, and basically all the scrap iron is cleaned, so that the adverse effect caused by the scrap iron falling on the inner surface of the spindle bush is avoided; meanwhile, the arrangement position of the magnet rod is beneficial to positioning the press-fitting block above the main shaft bushing; when the main shaft bushing and the crankshaft are overhauled, the main shaft bushing cover is conveniently lifted from or into the machine body by using the invention, the operation is safe, the time and the labor are saved, and the overhauling progress is improved.
