Description
Technical field
The utility model relates to Piston Machining technical fields, and in particular to a kind of jig on machining piston head.
Background technique
Currently, the jig on machining piston head has been cooperated using head pull rod (see Fig. 1) and head positioning seat (see Fig. 2)
At, it is shown.It is fixed with bolt (passing through piston pin hole) since head pull rod is inserted between two piston pin holes of piston
's.This results in the through-hole on the pull rod of head to must assure that and bolt can be made to pass through, so that size A(be made to see Fig. 1) become smaller, it answers
Power is concentrated, and is easy to happen and is burst apart.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of reasonable machining piston head of design
Jig.
To achieve the above object, the utility model uses following technical scheme:
A kind of jig on machining piston head, including positioning seat, pull rod and bolt, bolt are threaded through two pistons of piston
On pin hole, piston is set in the upper end of positioning seat, and the middle part of the positioning seat is equipped with a pilot hole, and the pull rod includes drawhead
Portion and the body of rod, the rod head are equipped with through-hole, and the through-hole is set on the bolt between two piston pin holes, pull rod
The body of rod, which passes through, pilot hole and to extend outwardly, the rod head perpendicular to pull rod center line view field by the body of rod perpendicular to drawing
Chamfered transition is equipped in the view field of bar center line is covered on, between the rod head and the body of rod to connect, the chamfering
Stub end is connected with rod head, and the small head end of the chamfering is connected with the body of rod, the rank of the pilot hole and positioning seat upper surface
The place of connecing is equipped with the inclined-plane matched with chamfering.
Further, the chamfering is chamfer.
The size of the chamfer is 5mm × 5mm.
The utility model uses above technical scheme, and chamfered transition is arranged between rod head and the body of rod and connects, accordingly
The joining place in positioning seat pilot hole with positioning seat upper surface the inclined-plane that matches with the chamfering is set so that drawhead
The size A in portion becomes larger, to substantially improve the distribution of stress concentration, and prevents phenomenon of bursting apart herein, extends processing and lives
The service life of plug head jig.
Detailed description of the invention
The utility model is described in further details below in conjunction with the drawings and specific embodiments；
Fig. 1 is the pull rod schematic diagram of the jig on existing machining piston head；
Fig. 2 is the positioning seat schematic diagram of the jig on existing machining piston head；
Fig. 3 is the pull rod schematic diagram of the jig on the utility model machining piston head；
Fig. 4 is the positioning seat schematic diagram of the jig on the utility model machining piston head；
Fig. 5 is the jig schematic diagram on the utility model machining piston head.
Specific embodiment
As shown in one of Fig. 3-5, the jig on the machining piston head of the utility model, including positioning seat 1, pull rod 2 and insert
Pin 3, bolt 3 are threaded through on two piston pin holes of piston 4, and piston 4 is set in the upper end of positioning seat 1, in the positioning seat 1
Portion is equipped with a pilot hole 11, and the pull rod 2 includes rod head 21 and the body of rod 22, and the rod head 21 is equipped with through-hole 211,
The through-hole 211 is set in 3 on the bolt between two piston pin holes, and the body of rod 22 of pull rod 2 passes through pilot hole 11 and to extension
Stretch, the rod head 21 perpendicular to 2 center line of pull rod view field by the body of rod 22 perpendicular to the projected area of 2 center line of pull rod
23 transition of chamfering is equipped in domain is covered on, between the rod head 21 and the body of rod 22 to connect, the stub end of the chamfering 23 and
Rod head 21 connects, small head end and the body of rod 22 connection of the chamfering 23, the rank of the pilot hole 11 and 1 upper surface of positioning seat
The place of connecing is equipped with the inclined-plane 12 matched with chamfering 23.
Preferably, the chamfering 23 is 45 ° of chamfers, the size of chamfer is 5mm × 5mm.
The utility model using the above structure, is arranged 23 transition of chamfering between rod head 21 and the body of rod 22 and connects, from
And the size A of rod head is become larger, to substantially improve the distribution of stress concentration, and it is existing to prevent to burst apart herein
As extending the service life of machining piston head jig.
