Camshaft pulse disk press fitting elasticity forces tight device, characterized in that including locating piece, the bullet connecting with pressing head of packing press
Property force tight device, the end face of the locating piece is equipped with the cavity for placing pulse disc；The interior of the locating piece is vertically equipped with
Sliding eye, the sliding eye bottom hole are equipped with and force tight slot, and tight slot is forced to be connected to sliding eye；The elasticity force tight device include pull rod,
Spring forces tight block, pin, and described to force tight block to be placed in force in tight slot, the length for forcing tight slot is greater than the length for forcing tight block；
Described pull rod one end is equipped with limited block, and the other end protrudes into sliding eye and forces tight block screw thread to connect with forcing in tight slot
It connects, pull rod, which is slided and driven in sliding eye, forces tight block to slide forcing in tight slot；The spring is placed on pull rod, is placed in pull rod
Limited block and sliding eye aperture between；The notch for forcing tight slot is located at the side wall endface of locating piece, and the pin, which is placed in, forces
On tight block and stretching is forced outside tight slot notch.
Further, 2 positioning pins are axially arranged with along locating piece in the cavity of the locating piece.
Further, described to force tight block for c-type flat key structure.
Further, described that tight slot ratio is forced to force the long 3-5mm of tight block.
Further, the sliding eye is perpendicular to horizontal plane.
Further, described to force tight block in the one end connecting with pull rod, which is greater than sliding eye hole floor space.
The utility model first knocks in pin in the mounting hole for forcing tight block in assembling, then tight block will be forced to be put into locating piece
Approach in block slot, spring pass through pull rod after pull rod is penetrated in the sliding eye of locating piece, while rotating rod be allowed to head with
It forces tight block to realize to be threadedly coupled, and makes spring compression stress.When the utility model is used, pulse disc to be placed in the sky of locating piece
It is intracavitary, 2 positioning pins in locating piece cavity are inserted into respectively in 2 concave tooth of pulse disc, Primary Location is carried out to pulse disc；
Then pull rod is pushed down on, makes to force tight block to slide forcing in tight slot, the pin positioned at locating piece side wall end face is made to catch on pulse disc
Another concave tooth carries out precise positioning to pulse disc.
The utility model changes the fixed location structure of traditional pulse disk, and there is certain elasticity to force tight effect, this reality
It is had the advantage that with novel
1) it forces tight block that can slide, and elastic can catch on the concave tooth of pulse disc, force tight reliable, positioning accuracy height；
2) facilitate operation, it is high-efficient, it is not easy to scratch pulse panel surface.

Specific embodiment
The utility model is further illustrated in conjunction with the accompanying drawings and embodiments.
As shown, camshaft pulse disk press fitting elasticity forces tight device, tight device is forced to form by locating piece and elasticity.Positioning
The end face of block is equipped with the cavity 3 for placing pulse disc, is axially arranged with 2 positioning pin 11(along locating piece in the cavity of locating piece and positions
The position of pin is corresponding with 14 position of concave tooth of pulse disc 12).The interior of locating piece is vertically equipped with sliding eye 4(sliding eye and hangs down
Directly in horizontal plane), sliding eye bottom hole is equipped with and forces tight slot 5, and tight slot is forced to be connected to sliding eye.It includes pull rod 6, bullet that elasticity, which forces tight device,
