Description
Art
The invention belongs to vehicle compressor technical field, especially relate to a kind of spheroidal graphite cast-iron flat tiltedly
Dish and production method thereof.
Background technology
In present automobile, air-conditioning is already known to requisite part on automobile.Automobile
Air-conditioning is to use special compressor to realize refrigeration, and wherein oblique tray type compressor is air conditioning for automobiles
Upper conventional compressor, this compressor be dependent on rotating shaft in certain tilt the rotation of swash plate
Motion drives piston or piston rod reciprocating to realize gas compression.Wherein swash plate is this
Part important on compressor, present swash plate makes the flat swash plate generally having outside and is fixed on
Internal swash plate body composition, and present flat swash plate material is pyrite, the both ends of the surface processing of product
Require for strengthening surface abrasion resistance after completing to spray molybdenum bisuphide coating, the roughness of biend
Ra0.25.Pyrite is expensive, and is relatively difficult to ensure the thickness of card product during molybdenum bisuphide coating, puts down
(gauge of product is 60-0.1mm, plane for face degree and the depth of parallelism and roughness requirements
Degree 0.004mm, the depth of parallelism requires as 0.005mm), have impact on the total quality of product.Simultaneously
The material of pyrite itself, and processing charges is the highest.
Summary of the invention
For above-mentioned problem, it is an object of the invention to provide a kind of use spheroidal graphite cast-iron is material
Material, machining accuracy is higher, the flat swash plate of spheroidal graphite cast-iron that cost is lower and production method thereof.
The technical solution adopted for the present invention to solve the technical problems is: the flat swash plate of this spheroidal graphite cast-iron
For circular plate shape, using spheroidal graphite cast-iron processing, the screw thread being machined with through top and bottom in the middle of it leads to
Hole, the outside of described tapped through hole is evenly equipped with the connection through hole of through top and bottom, and described connection is led to
It is machined with respectively on top and bottom outside hole and the cannelure of plectane concentric, described cannelure
Bottom surface is plane, and the plane of described ring slot outside uses high-frequency therapeutic treatment respectively.
As preferably, the annular center line of the described cannelure bottom surface of upper plane is machined with annular
Half slot.
As preferably, the inner side edge of described cannelure designs for arc chord angle, outside described cannelure
Side is oblique angle design.
As preferably, the processing number of described connection through hole is 3.
A kind of production method of the flat swash plate of this spheroidal graphite cast-iron, including step produced by below:
One, casting normalizing hair slope；
Two, rough turn endoporus；
Three, car one side, cylindrical, annular groove；
Four, bore connect through hole '
Five, through hole chamfering, deburring are connected；
Six, high-frequency therapeutic treatment；
Seven, a hole bur is removed；
Eight, leaching antirust oil is cleaned；
Nine, pick up eventually, pack warehouse-in.
The beneficial effects of the present invention is: this flat swash plate of ink cast iron uses spheroidal graphite cast-iron to be raw material,
Replacing original pyrite raw material, this makes the material cost of whole part be substantially reduced；Pass through
High frequency treatment pats the upper and lower surface of swash plate so that it is reach wear-resisting requirement, by processing cannelure
Structure makes high-frequency therapeutic treatment more easy, ensure that the toughness of whole part simultaneously, part
Difficulty of processing is greatly reduced, and the processing cost of whole part effectively reduces.
Accompanying drawing explanation
Fig. 1 is the generalized section of the flat swash plate of spheroidal graphite cast-iron.
Fig. 2 is the enlarged drawing in Fig. 1 at A.
Fig. 3 is the enlarged drawing in Fig. 1 at B.
Fig. 4 is the enlarged drawing in Fig. 1 at C.
Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings:
As shown in the embodiment shown in fig, the flat swash plate of this spheroidal graphite cast-iron is circular plate shape, adds in the middle of it
Work has the tapped through hole 1 of through top and bottom, the outside of described tapped through hole be evenly equipped with through up and down
The connection through hole 2 in face, tapped through hole 1 and the described concrete processing structure such as figure being connected through hole 2
Shown in 2, connect through hole about 2 and be machined with chamfering, it is simple to the insertion of union piece.Screw thread leads to
Hole about 1 is machined with chamfering, it is simple to internal threaded male component connects.This spheroidal graphite cast-iron is flat tiltedly
Dish use spheroidal graphite cast-iron processing, the top and bottom outside described connection through hole 2 are machined with respectively with
The cannelure 3 of plectane concentric, the bottom surface of described cannelure 3 is plane, described upper-lower position
High-frequency therapeutic treatment is used respectively in plane outside cannelure 3.
This flat swash plate of ink cast iron uses spheroidal graphite cast-iron to be raw material, replaces original pyrite raw material, this
The material cost making whole part is substantially reduced；The upper following table of swash plate is patted by high frequency treatment
Face so that it is reach wear-resisting requirement, makes high-frequency therapeutic treatment more by processing cannelure 3 structure
Easy, ensure that the toughness of whole part simultaneously, the difficulty of processing of part is greatly reduced,
The processing cost of whole part effectively reduces.
As it is shown on figure 3, be machined with ring on the annular center line of described cannelure 3 bottom surface of upper plane
The half slot 4 of shape.Described half slot 4 is easy to determine the position of described cannelure 3, the most partly
Circular groove can be used to mounting O-shaped rings part and seals.
The inner side edge of described cannelure 3 is that arc chord angle 31 designs, and the outer side edges of cannelure 3 is
Oblique angle 32 designs.Arc chord angle 31 can effectively reduce stress, and oblique angle 32 can be convenient for assembly
Part at cannelure 3 tilts to skid off.
The processing number of described connection through hole 2 is 3.
The flat swash plate of this spheroidal graphite cast-iron includes step produced by below:
One, casting normalizing hair slope；
Two, rough turn endoporus；
Three, car one side, cylindrical, annular groove；
Four, bore connect through hole '
Five, through hole chamfering, deburring are connected；
Six, high-frequency therapeutic treatment；
Seven, a hole bur is removed；
Eight, leaching antirust oil is cleaned；
Nine, pick up eventually, pack warehouse-in.
In order to ensure the wearability requirement of both ends of the surface, biend is carried out high-frequency quenching process and returns
Fire processes.Both ends of the surface high-frequency therapeutic treatment carries out grinding again after completing, processing ensures gauge, puts down
Row degree and flatness and roughness requirements.
