Abstract
The utility model relates to an assembly tool for a liner bushing of a camshaft of a multi-cylinder diesel engine, in particular to a device for press-mounting of the linear bushing of the camshaft of the multi-cylinder diesel engine. The device comprises a pressure rod of the linear bushing of the camshaft, wherein a fixing head of the linear bushing of the camshaft is arranged at the front end of a pressure rod body, and the rear end surface of the pressure rod body is the spherical surface. The rear end surface of the pressure rod is the spherical surface, and the contact between a pressure head and the pressure rod of an oil press becomes the point contact, thereby eliminating the manufacturing error generated in the mounting process of a press-mounting tool. During the operation process of the diesel engine, the phenomena of large noise and large shock caused by the part of the camshaft can be greatly improved. The service lives of the camshaft and the linear bushing are further prolonged and the performances of the diesel engine are also greatly improved.
Description
Technical field
The utility model belongs to Diesel Engine Technique Field, is specifically related to a kind of multi-cylinder diesel engine cam shaft bush assembly tool that is used for.
Background technology
Cam shaft bush is one of important accessory of diesel engine, and the axiality between surface roughness, cylindricity and each grade cam shaft bush hole after the cam shaft bush assembling is very big to the performance impact of diesel engine.Modification in various degree can appear because cam shaft bush press-fits in the process; Exceed allowed band if press-fit the back deflection; Will make the noise of diesel engine big, shake greatly, the performance of diesel engine also can receive very big influence, and the life-span of camshaft and lining also can shorten greatly.Assembly tool directly influences the quality that press-fits of cam shaft bush.The depression bar rear end face is the plane in original press mounting tool; The pressure head of hydraulic press also is the plane; The error of perpendicularity rigid of transmission of depression bar axis and end face makes the cam shaft bush unbalance stress to cam shaft bush, thereby phenomenons such as cylindricity is overproof, surface galling occur.Directly influence the performance indications of diesel engine.
The utility model content
In order to solve phenomenons such as cam shaft bush is poor in the surface roughness that press-fits the back appearance, cylindricity is overproof, the utility model has been done improvement to the depression bar end on the original basis.
The Technological improvement plan of realizing above-mentioned purpose is following:
Be used to press-fit the device of multi-cylinder diesel engine cam shaft bush, comprise cam shaft bush depression bar 1, the front end of depression bar 1 body is provided with cam shaft bush fixing head 5, and improvement is: the rear end face 6 of said depression bar 1 body is spherical.
The utility model is a sphere through adopting the depression bar rear end face, becomes a contact to the pressure head of hydraulic press with contacting by the face contact of depression bar, has eliminated the foozle of the generation of press mounting tool in installation process.The noise that is partly caused by camshaft in the diesel engine running is big, shakes big phenomenon and is greatly improved.Camshaft and lining have also prolonged service life, and the performance of diesel engine has also had very big improvement.
Description of drawings
Fig. 1 is the utility model configuration diagram.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
According to practical implementation and combine accompanying drawing, the utility model is done further detailed explanation below.
Embodiment:
Referring to Fig. 1 and Fig. 2; Be used to press-fit the instrument of multi-cylinder diesel engine cam shaft bush; Comprise cam shaft bush depression bar 1, the device of stationary cam neck bush is arranged on depression bar 1: the front end of depression bar 1 body is provided with cam shaft bush fixing head 5, and the middle part of lining fixing head 5 is provided with radially step through-hole; The step through-hole two ends are the design of concentric reducer opening, the steel ball 2 of packing into successively, cylindrical screw contract spring 3 and end face holding screw 4; Steel ball 2 has the outer little opening part of through hole that is exposed at of part.Cam shaft bush is contained on the lining fixing head 5 of depression bar 1, and the oilhole on the lining is aimed at steel ball 2, and steel ball 2 holds out against cam shaft bush under the effect of cylindroid helical-coil compression spring 3, it can not come off.The rear end face 6 of depression bar 1 body is a spherical.Form point between hydraulic press pressure head and the depression bar and contact, so just effectively discharged the foozle of depression bar, the distortion inaccuracy of cam shaft bush also reduces thereupon, thereby has improved product quality.
When being used for process operation, the depression bar that cam shaft bush is housed is aimed at the body camshaft hole, the pressure head of hydraulic press is pressed on the spherical of depression bar rear end face, makes cam shaft bush be pressed into the tram, carefully takes out depression bar and gets final product.
The utility model provides a kind of assembly tool of reliable assembling multi-cylinder diesel engine cam shaft bush.
