Abstract
The utility model relates to a special tool for disassembling a cylinder cover positioning pin of a diesel engine. One end of a cylindrical chuck of the tool is a screw rod; a fastening screw nut is arranged on the screw rod in match; the other end of the chuck is a conical platform; a pin hole in match with the positioning pin of the cylinder cover is formed in the middle of the large-diameter end of the conical platform in the axial direction; more than four axial grooves are uniformly formed in the circumference of the conical platform corresponding to the pin hole; one end of each axial groove passes through the large-diameter end of the conical platform, and the other end of each axial groove is limited in the middle of the pin hole, so that the conical platform is formed into a clamping jaw; the screw rod end of the clamping jaw is connected with one end of a fixing rod through a thread; a sliding handle is sleeved on the fixing rod; the other end of the clamping jaw is connected with one end of the fixing rod through the thread. When the special tool is used for disassembling the positioning pin, the clamping jaw of the chuck is sleeved on the positioning pin, the fastening screw nut is screwed downwards, then the clamping jaw tightly clamps the positioning pin, and subsequently through vertical movement of the sliding handle, the positioning pin can be disassembled. The special tool is simple and convenient to operate and can save the time and labor.
Description
Technical field
The utility model belongs to diesel engine production technical field, is specifically related to a kind of specific purpose tool for cylinder cover for diesel engine disassembling positioning pin.
Background technology
In the production of diesel engine and maintenance service after sale, often can run into situations such as need to changing cylinder head, body.At this moment, will relate to the dismounting problem of cylinder head dowel pin.Because alignment pin and body are that slight interference coordinates, make the dismounting of alignment pin more difficult.Workpeople, when dismounting alignment pin, can only weld iron staff and by iron hammer, knocks or by chisel, on alignment pin, carve out indentation on alignment pin, re-uses vice clamping and makes it to depart from.Usually do like this and can destroy dowel hole, and waste time and energy.
Utility model content
For do not damage dowel hole and make the dismounting of cylinder cover for diesel engine alignment pin simple, convenient, the utility model provides a kind of specific purpose tool for cylinder cover for diesel engine disassembling positioning pin.
Specific purpose tool for cylinder cover for diesel engine disassembling positioning pin comprises columniform chuck 1, and chuck 1 one end is screw rod, coordinates to be provided with to tighten up nut 2 on screw rod, and the other end is the frustum of a cone; The smaller diameter end of the frustum of a cone is connecting screw rod, the larger diameter end of the frustum of a cone axially middle part offers the pin-and-hole coordinating with cylinder head dowel pin 7, uniformly on the frustum of a cone circumference corresponding with pin-and-hole offer four above axial grooves, one end of every axial groove connects the larger diameter end of the frustum of a cone, the other end terminates in the middle part of pin-and-hole, makes the frustum of a cone of chuck 1 form jaw; The screw rod end of chuck 1 axially offers screwed hole, and be connected one end of fixed bar 4 of screwed hole, is arranged with sliding handle 3 on fixed bar 4, and the other end of fixed bar 4 is screw rod, and limited block 5 and nut 6 are being connected on the screw rod of fixed bar 4.
Uniformly on the frustum of a cone circumference corresponding with pin-and-hole offer six axial grooves.
The length of described fixed bar 4 is 200～260 ㎜, and diameter is 8～10 ㎜.
When the utility model is dismantled for the alignment pin 7 of cylinder head, the jaw of chuck 1 is enclosed within on alignment pin 7, is screwed down and tightens up nut 2, make jaw clamping and positioning pin 7, then, by the moving up and down of sliding handle 3, clash into fixed bar 4, disassembling positioning pin can be got off.Both saved time, laborsaving again, and simple to operation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model is used state diagram.
Sequence number in upper figure: chuck 1, tighten up nut 2, sliding handle 3, fixed bar 4, limited block 5, nut 6, alignment pin 7, pin-and-hole 8.
The specific embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is further described.
Referring to Fig. 1, for the specific purpose tool of cylinder cover for diesel engine disassembling positioning pin, comprise columniform chuck 1, chuck 1 one end is screw rod, coordinates to be provided with to tighten up nut 2 on screw rod, the other end is the frustum of a cone; The smaller diameter end of the frustum of a cone is connecting screw rod, the larger diameter end of the frustum of a cone axially middle part offers the pin-and-hole coordinating with cylinder head dowel pin, uniformly on the frustum of a cone circumference corresponding with pin-and-hole offer six axial grooves, one end of every axial groove connects the larger diameter end of the frustum of a cone, the other end terminates in the middle part of pin-and-hole, makes the frustum of a cone of chuck 1 form jaw.The screw rod end of chuck 1 axially offers screwed hole, and be connected one end of fixed bar 4 of screwed hole, is arranged with sliding handle 3 on fixed bar 4, and the other end of fixed bar 4 is screw rod, and limited block 5 and nut 6 are being connected on the screw rod of fixed bar 4.The length of fixed bar 4 is 250 ㎜, and diameter is 8 ㎜.
Referring to Fig. 2, alignment pin 7 coordinates on the cylinder body that is arranged on diesel engine by slight interference, in the time of need to dismantling alignment pin 7, first the jaw of the chuck of specific purpose tool 1 is enclosed within on alignment pin 7, by rotation, tightens up nut 2, the jaw of chuck 1 is shunk, jaw by chuck 1 shrinks clamping and positioning pin 7, then, by the moving up and down of sliding handle 3, clashes into the limited block 5 on fixed bar 4, make it to drive alignment pin 7, and alignment pin 7 and the pin-and-hole 8 of cylinder body are departed from.
Use the utility model can dismantle easily and efficiently cylinder head dowel pin 7, can not damage the pin-and-hole 8 on cylinder body.
