The tool comprises a front connector and a rear connector which are connected through a guide tube, wherein a sheath is mounted outside of the guide tube, a hexagon connector is arranged in the rear connector and is connected with an ejector pin through a cylindrical pin, and the ejector pin is mounted in the guide tube, the front end of the ejector pin is clamped into the front connector, and a stop pin is arranged in the front connector.
Description
(1) technical field
The utility model relates to the equipment frock field that is used for diesel engine production maintenance, is specially a kind of instrument of assembling and disassembling camshaft bush of diesel engine of novelty.
(2) background technology
In diesel engine production, trial-manufacture of sample, maintenance process, generally to install and remove cam shaft bush; generally can adopt special-purpose pressing machine; when but special-purpose pressing machine is worked cam shaft bush is all press-fited or just all dismountings; and in the diesel engine small lot batch manufacture particularly in the maintenance process; run in the diesel engine a certain or several grades of cam shaft bushes wearing and tearing and need to change through regular meeting; remaining is kept, and this situation just is not suitable for operating with special-purpose pressing machine.
(3) summary of the invention
At the problems referred to above, the utility model provides a kind of instrument of assembling and disassembling camshaft bush of diesel engine of novelty, and it is simple in structure, and is portable, easy and simple to handle, does not need special maintenance, and cost is low.
Its technical scheme is such, it is characterized in that: it comprises front connector and back joint, described front connector is connected by guide pipe with described back joint, described guide pipe outside is equipped with sheath, be provided with hexagonal shoulder nipple in the joint of described back, described hexagonal shoulder nipple is connected with push rod by straight pin, and described push rod is installed in the guide pipe, described front connector is gone in the clamping of described push rod front end, is provided with backing pin in the described front connector.
It is further characterized in that: described front connector has longitudinal sliding slot; Described backing pin is installed in the described sliding tray; Described backing pin radially is connected with the steel wire that resets; Screw in described reset steel wire and the described front connector axially extending bore is fastening; Described push rod end face is the conical surface; Described backing pin working face is the plane.
The instrument of the assembling and disassembling camshaft bush of diesel engine of the utility model structure, it is simple in structure, easy to carry, easy and simple to handle, cost is low, it both can install and remove whole cam shaft bushes also can install and remove wherein any one grade or several grades of cam shaft bushes, and can not damage cam shaft bush in assembling and dissembling process, is specially adapted to the engine maintenance industry.
(4) description of drawings
The structural representation that Fig. 1 looks for the utility model master.
(5) specific embodiment
See Fig. 1, the utility model comprises front connector 3 and back joint 11, front connector 3 is connected by guide pipe 6 with back joint 11, guide pipe 6 outsides are equipped with sheath 7, be provided with hexagonal shoulder nipple 10 in the back joint 11, hexagonal shoulder nipple 10 is connected with push rod 8 by straight pin 9, and push rod 8 is installed in the guide pipe 6, front connector 3 is gone in push rod 8 front end clampings, is provided with backing pin 5 in the front connector 3.Front connector 3 has longitudinal sliding slot; Backing pin 5 is installed in the above-mentioned sliding tray; Backing pin 5 radially is connected with the steel wire 4 that resets; The steel wire 4 that resets is fastening with the screw 1 in front connector 3 axially extending bores; Push rod 8 end faces are the conical surface; Backing pin 5 working faces are the plane.Among Fig. 1,2 is spring washer, and it prevents that screw 1 is loosening; 12 are fluting awl end holding screw, and it prevents that the back joint is loosening.
The concrete course of work of the utility model structure once is described below:
1, cam shaft bush press-fits operation: the utility model structure tool is introduced in the camshaft hole, with the hexagonal shoulder nipple 10 in the joint 11 behind the stubborn instrument of standard inner hexagon spanner, by push rod 8 backing pin 5 is ejected in the sliding tray of front connector 3, it is spacing to the backing pin place that cam shaft bush is enclosed within front connector 3 outsides, the end face of joint 11 after the hammering again is with bushing press body precalculated position;
2, cam shaft bush is torn the cover operation open: the utility model structure tool is introduced in the camshaft hole, with the hexagonal shoulder nipple 10 in the stubborn back of the standard inner hexagon spanner joint 11, by push rod 8 backing pin 5 is ejected in the sliding tray of front connector 3, it is spacing until the backing pin place that front connector 3 is inserted in the cam shaft bush, end face by joint 11 behind the hammering afterbody extrudes cam shaft bush in the body camshaft hole.
3, finish press-fiting or tearing open after the cover operation with the standard inner hexagon spanner and instead twist hexagonal shoulder nipple 10 in the back joint 11 of cam shaft bush, with push rod 8 withdrawals, at this moment backing pin 5 is retracted in the sliding tray of front connector 3 under the effect of the steel wire 4 that resets, and takes out this instrument.
Because cam shaft bush and camshaft endoporus are interference fit, when 11 end faces of joint behind the fullering tool, hammer force passes to cam shaft bush by backing pin 5, finishes the disassemble and assemble work of cam shaft bush.
