Abstract
It the utility model discloses a kind of positioning seat for bent axle positioning tool, solves the problems, such as that the positioning seat service life of existing bent axle positioning tool is low, there is triangulation location slot on the positioning seat, it is characterized in that：Further include having polylith carbide alloy board, there is strip on the side wall of the carbide alloy board, two of the triangulation location slot tilt and all have the card slot engaged for strip on cell wall, the carbide alloy board is connected together by strip and card slot on the inclination cell wall of triangulation location slot, and the supporting surface for being used to support bent axle is formed between two carbide alloy boards tilted on cell wall, the usage time of positioning seat is improved by carbide alloy board.
Description
Technical field
The utility model is related to a kind of positioning seats for bent axle positioning tool.
Background technology
Bent axle is most important component in engine.It bears the power that connecting rod transmits, and is transformed into torque and passes through song
Axis exports and other attachmentes on engine is driven to work.Bent axle is by the centrifugal force of gyrating mass, the gas inertia of mechanical periodicity
The collective effect of power and reciprocal inertia force makes bent axle bear the effect of flexion torsion load.Therefore it is required that bent axle have it is enough strong
Degree and rigidity, journal surface need are wear-resisting, work is uniform, balance is good.
Bent axle in process of production, needs that bent axle is fixedly clamped using frock clamp, is then drilled, milling behaviour
Make.In the prior art, the positioning seat of fixed crankshaft is used in frock clamp, structural strength to be relatively low, is fixedly clamped to bent axle
After a period of time, the cell wall meeting crimp of the locating slot of positioning seat causes positioning seat to be unable to normal use, need to be replaced,
Lead to the increase of production cost.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of positioning seat for bent axle positioning tool.
To achieve the above object, the utility model provides following technical solution：
A kind of positioning seat for bent axle positioning tool has triangulation location slot on the positioning seat, further includes having polylith
Carbide alloy board, has strip on the side wall of the carbide alloy board, and two of the triangulation location slot tilt and have on cell walls
There is a card slot engaged for strip, the carbide alloy board is connected together by strip and card slot in the tipper of triangulation location slot
On wall, and the supporting surface for being used to support bent axle is formed between two carbide alloy boards tilted on cell wall.
Preferably, the slot bottom of the card slot offers screw hole one, and screw hole two, the spiral shell are offered on the carbide alloy board
Kong Yiyu screw holes two dock and are equipped with fixing bolt.
Preferably, have counterbore, the counterbore corresponding with threaded hole two on the carbide alloy board.
Preferably, the bottom of the positioning seat offers location hole.
The advantages of the utility model is：When bent axle is fixed, it is supported on carbide alloy board, avoids bent axle and triangulation location
The inclination cell wall of slot be in direct contact and the structural strength of carbide alloy board, abrasion resistance are preferable, therefore effectively extend
The usage time of positioning seat, reduces production cost.
Description of the drawings
The schematic diagram for the positioning seat for bent axle positioning tool that Fig. 1 is provided by the present embodiment.
Specific implementation mode
Positioning seat by Fig. 1 to the utility model for bent axle positioning tool is further described.
A kind of positioning seat for bent axle positioning tool includes two pieces of carbide alloy boards 3, the side of the carbide alloy board
There is strip on wall, there is triangulation location slot 2 on the positioning seat 1, have on two inclination cell walls of the triangulation location slot 2
There is a card slot engaged for strip, the carbide alloy board 3 is connected together by strip and card slot in the inclination of triangulation location slot 2
On cell wall, and the supporting surface for being used to support bent axle is formed between two carbide alloy boards tilted on cell wall；By card slot with
The snap fit of strip increases the structural strength connected between carbide alloy board and positioning seat.
Further, each piece of carbide alloy board 3 is by two pieces of 31 inline formation of hard alloy blocks, the setting energy
Enough facilitate the replacement of carbide alloy board, you can be replaced with the part to carbide alloy board, improve the utility model use
Flexibility.
Further, the slot bottom of the card slot offers screw hole one, and screw hole two is offered on the carbide alloy board, described
Screw hole one docks with screw hole two and is equipped with fixing bolt 4, which realizes detachably connecting between carbide alloy board and positioning seat 1
It connects, convenient dismounting, replacement between the two.
Further, there is counterbore, the counterbore is corresponding with threaded hole two, and the counterbore is for supplying on the carbide alloy board
The head of bolt stores, and ensures the flatness of supporting surface, stablizes for bent axle and supports.
Further, the bottom of the positioning seat 1 offers location hole, which can realize this positioning seat 1 at it
Installation in his tooling.
Further, further include having crank arm mating groove 5 on positioning seat 1, which is located at triangulation location slot
2 one end, the crank arm mating groove 5 are used to coordinate for the crank arm of bent axle, realize that 1 ontology of positioning seat is fixed to the axial direction of bent axle
Position, saves the setting of external axially position component.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
