Abstract
The utility model relates to a press mounting tool for an engine maintenance assembly locking block. The press mounting tool comprises a handle, a pressing head, a spring and a mandrel. The handle is in threaded connection with the pressing head. The spring and the mandrel are sequentially installed in the central hole of the pressing head. A through hole is arranged in the center of the mandrel. The lower end of the mandrel is conical. The external conical surface of the mandrel is fit with the internal conical surface of a valve spring seat. The conical lower end of the mandrel under the pressure of the spring is exposed out of the central hold of the pressing head. The aperture of the central hole is less than the diameter of the straight section of the mandrel. The utility model has the advantages that the structure is simple and practical, the weight is light, the carrying is convenient and the press mounting of the valve locking block of the engine under all kinds of environments is facilitated.
Description
Technical field
The utility model is specifically related to a kind of press mounting tool that is used for engine maintenance assembling lock dog.
Background technology
At present in the maintenance of engine, to engine valve after dismounting, if in the open air or the maintenance place do not have valve lock dog pressing machine, be to carry out site-assembledly, it directly influences the engine maintenance progress.
Summary of the invention
The utility model does not have valve lock dog pressing machine at open-air and maintenance place, can't site-assembled situation, and a kind of simple and practical, the light weight of design, the press mounting tool that is used for engine maintenance assembling lock dog easy to carry.
The technical solution of the utility model is as follows:
A kind of press mounting tool that is used for engine maintenance assembling lock dog, described press mounting tool comprises handle, pressure head, spring and axle; Described handle is threaded with pressure head, mounting spring and axle successively in the centre bore of described pressure head; There is through hole at described axle center, the lower end of axle is tapered, the inner conical surface of its male cone (strobilus masculinus) and cotter seat coincide, and axle its tapered lower end under the pressure of spring is exposed to the centre bore of pressure head, and the orifice diameter of centre bore is less than the diameter of the d-axis section of axle.
When using press mounting tool, press mounting tool is by applying pressure to handle, the centre bore of axle leads by engine valve stem, the male cone (strobilus masculinus) of axle lower end is fitted by the pressure of its spring and the inner conical surface of cotter seat, its head withstands lock dog, the pressure head top presses down cotter seat, valve spring, and the valve lock dog moves down and slips into the engine valve stem annular groove; Decompression, the valve spring return, the valve lock dog is locked cotter seat in annular groove, and lock dog promptly is assembled to the position.
Simple and practical, the light weight of this press mounting tool, easy to carry, be convenient to engine and under various environment, carry out the valve lock dog and press-fit.
