Abstract
The invention relates to a special tool for diesel engine air cylinder cover locating pin disassembling. One end of a cylindrical clamping head of the tool is a screw rod which is provided with a fastening nut in a matching mode. The other end of the cylindrical clamping head of the tool is a cone table. A pin hole matched with an air cylinder cover locating pin is formed in the middle in the axial direction of the large-diameter end of the cone table. More than four axial grooves are evenly formed in the periphery of the cone table corresponding to the pin hole. One end of each axial groove penetrates through the large-diameter end of the cone table, the other end of each axial groove is stopped in the middle of the pin hole, and accordingly the cone table forms a clamping jaw. The screw rod end of the clamping head is connected with one end of a fixing rod through threads. A sliding handle is arranged on the fixing rod in a sleeved mode. The other end of the fixing rod is connected with a limiting block and a nut through threads. When the tool is used for locating pin disassembling, the clamping jaw of the clamping head is arranged on the locating pin in a sleeved mode, the fastening nut is screwed downwards, so that the clamping jaw clamps the locating pin, then the sliding handle moves up and down so that the locating pin can be disassembled, operation is easy and convenient, and time and labor are saved.
Description
Technical field
The invention belongs to the diesel engine production technical field, be specifically related to a kind of specific purpose tool for the 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 and need to change the situations such as 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.The workpeople, when the dismounting alignment pin, can only weld iron staff and knocks by iron hammer or carve out indentation by chisel on alignment pin on alignment pin, re-uses the vice clamping and makes it to break away from.Usually do like this and can destroy dowel hole, and waste time and energy.
Summary of the invention
For do not damage dowel hole and make the dismounting of cylinder cover for diesel engine alignment pin simple, convenient, the invention provides a kind of specific purpose tool for the cylinder cover for diesel engine disassembling positioning pin.
Specific purpose tool for the cylinder cover for diesel engine disassembling positioning pin comprises columniform chuck 1, and chuck 1 one ends are screw rod, on screw rod, coordinates to be provided with to tighten up nut 2, 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 8 coordinated with cylinder head dowel pin 7, the uniform axial groove offered more than four on the frustum of a cone circumference corresponding with pin-and-hole 8, 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 8, makes the frustum of a cone of chuck 1 form jaw; The screw rod end of chuck 1 axially offers screwed hole, and a be connected end of fixed bar 4 of screwed hole, be 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 ㎜.
The present invention during for the disassembling positioning pin of cylinder head, is enclosed within the jaw of chuck 1 on alignment pin 7, is screwed down and tightens up nut 2, makes jaw clamping and positioning pin 7, then, by the moving up and down of sliding handle 3, clashes into fixed bar 4, disassembling positioning pin can be got off.Both saved time, laborsaving again, and simple to operation.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is that the present invention uses 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 present invention is further described.
Referring to Fig. 1, comprise columniform chuck 1 for the specific purpose tool of cylinder cover for diesel engine disassembling positioning pin, chuck 1 one ends are screw rod, on screw rod, coordinate to be equipped with to tighten up nut 2, 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 8 coordinated with cylinder head dowel pin 7, uniformly on the frustum of a cone circumference corresponding with pin-and-hole 8 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 8, makes the frustum of a cone of chuck 1 form jaw.The screw rod end of chuck 1 axially offers screwed hole, and a be connected end of fixed bar 4 of screwed hole, be 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, while needing dismounting 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 broken away from.
Use the present invention can dismantle easily and efficiently cylinder head dowel pin 7, can not damage the pin-and-hole 8 on cylinder body.
