Abstract
The utility model provides a shaft body ejecting and drawing device, and belongs to the technical field of mechanical assembling and disassembling tools. The technical scheme adopted by the utility model is that the shaft body ejecting and drawing device comprises a supporting frame and a jack, wherein the supporting frame comprises a bottom plate; support bars are arranged on the two sides of the bottom plate; a fixed plate and a moving plate are respectively arranged at the upper ends of the support bars on the two sides of the bottom plate; semi-circular gaps are symmetrically arranged on the sides, close to the moving plate, of the fixed plate; moving grooves are further formed on the moving plate; the fixed plate is fixed at the upper end of the corresponding support bar; and the moving plate is movably arranged at the upper end of the corresponding support bar through bolts passing through the moving grooves. The shaft body ejecting and drawing device has the beneficial effects that the structure is simple, the use is convenient, and damage to mechanical parts is also avoided.
Description
Technical field
The utility model relates to a kind of mechanical handling instrument, relates in particular to a kind of axis body and pulls device.
Background technology
Bearing on the mechanical axis, shaft coupling and belt pulley are many takes the interference fit installation with axis body; When dismounting; Utilize hydraulic pressure to take off son, the imitation finger movement grips parts such as bearing from mechanical axis and pulls down by force, and is little and dynamics is inhomogeneous but hydraulic pressure is taken off sub-application of force area; Very easily slippage from the parts in unloading process, operation inconvenience and easily to and cause damage.
Summary of the invention
The purpose of the utility model is to provide a kind of simple in structure and axis body convenient disassembly to pull device.
The utility model is realized through following measure: a kind of axis body is pulled device; Comprise bracing frame and jack; Support frame as described above comprises base plate, and the both sides on the said base plate are provided with support bar, and the upper end of the said support bar of both sides is respectively arranged with fixed head and portable plate; The close side with said portable plate of said fixed head is symmetrically arranged with semicircle breach; Also be provided with loose slot on the said portable plate, said fixed head is fixed on the upper end of said support bar, and said portable plate is movably arranged on the upper end of said support bar through the bolt that passes said loose slot.
The concrete characteristics of the utility model also have, and said jack is arranged on the said base plate.
The beneficial effect of the utility model is: simple in structure, easy to use, and avoided mechanical part is caused damage.Jack is installed on the base plate of bracing frame; During use, the telescopic shaft of jack withstands an end of axis body and guarantees bearing below fixed head, regulates bolt and fixes portable plate; Make axis body just the breach on fixed head and the portable plate stretch out; Make the bearing retaining again below fixed head and portable plate, jack work, telescopic shaft upwards ejects axis body from parts can accomplish dismounting.
