Bounce is unable to reach to require.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided piston end surface endoporus bounce one can be controlled during one kind processing
Piston Inner within provisioning request rises flat surface grinding frock.
The object of the present invention is achieved like this：
A kind of piston Inner rises flat surface grinding frock, and it includes pedestal, cylinder, internal expanding mandrel, attachment screw and internal expanding chuck,
The pedestal includes upper pedestal and lower base, and the upper pedestal and lower base are arranged at by multiple bolt connections, the cylinder
The inside of lower base, and the telescopic end of cylinder is upward through upper pedestal, on the telescopic end of cylinder by vertical attachment screw with
Internal expanding mandrel is fixedly connected, the vertical section of internal expanding mandrel including hypomere and the conical section of upper end, the external diameter of conical section on to
Under be gradually reduced until outside dimension it is identical with vertical section, it is vertical on the outside dimension and upper pedestal of the vertical section of internal expanding mandrel
Through hole cooperate, the internal expanding chuck is arranged at the top of upper pedestal, and internal expanding chuck is arranged at the outside of internal expanding mandrel,
And the inner surface of internal expanding chuck has the inclined-plane to be cooperated with the conical section of internal expanding mandrel, and the outer surface of internal expanding chuck is hung down
Directly；Internal expanding chuck is flexible chuck.
Internal expanding chuck includes multi-disc flap valve.
A kind of piston Inner rise flat surface grinding frock operation principle it is as follows：
Cylinder is connected on base, internal expanding mandrel is connected on cylinder by attachment screw, and internal expanding mandrel is transported with cylinder
It is dynamic so that it unclamps with internal expanding chuck or is interference fitted from and has reached the purpose of release and Clamp blocks；
Clamped condition：Cylinder drives internal expanding mandrel to move downward, and by cone match, makes internal expanding chuck spreading, clamps zero
Part；
Releasing orientation：Cylinder promotes internal expanding mandrel to move upwards, and internal expanding chuck leans on the elasticity of itself, replys shape during reconditioning
State, unclamp part.
The base baseplane of reconditioning lower base is needed before use, it is desirable to flatness 0.005mm, 0.4 μm of roughness Ra, reconditioning
Afterwards, cylinder certain pressure is given, frock is in clamped condition, now reconditioning internal expanding chuck contacts surface with inner bore of part, it is desirable to
Circularity 0.003mm, with base baseplane perpendicularity 0.005mm, 0.4 μm of roughness Ra, it can now ensure that the bounce of part will
Ask.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention can increase the internal expanding chuck of frock and the contact area of piston inner hole, reduce fit-up gap to part end
The influence of face bounce, improves part quality.
Brief description of the drawings
Fig. 1 is that inventive piston Inner rises the structural representation of flat surface grinding frock.
Fig. 2 is the schematic diagram of piston details.
Wherein：
Upper pedestal 1, lower base 2, cylinder 3, internal expanding mandrel 4, attachment screw 5, internal expanding chuck 6.
Embodiment
Referring to Fig. 1, a kind of piston Inner of the present invention rises flat surface grinding frock, and it includes pedestal, cylinder 3, internal expanding mandrel
4th, attachment screw 5 and internal expanding chuck 6, the pedestal include upper pedestal 1 and lower base 2, and the upper pedestal 1 and lower base 2 are logical
Multiple bolts 7 to be crossed to connect, the cylinder 3 is arranged at the inside of lower base 2, and the telescopic end of cylinder 3 is upward through upper pedestal 1,
It is fixedly connected on the telescopic end of cylinder 3 by vertical attachment screw 5 with internal expanding mandrel 4, internal expanding mandrel 4 includes the vertical of hypomere
Section and the conical section of upper end, the external diameter of conical section is gradually reduced from the top down until outside dimension is identical with vertical section, internal expanding
The outside dimension of the vertical section of mandrel 4 is cooperated with the vertical through hole on upper pedestal 1, and the internal expanding chuck 6 is arranged at
The top of pedestal 1, and internal expanding chuck 6 is arranged at the outside of internal expanding mandrel 4, and the inner surface of internal expanding chuck 6 has and internal expanding
The inclined-plane that the conical section of mandrel 4 cooperates, the outer surface of internal expanding chuck 6 are vertical；Internal expanding chuck 6 is with certain elastic folder
Set, it can include multi-disc flap valve.
Operation principle：
Cylinder is connected on base, internal expanding mandrel is connected on cylinder by attachment screw, and internal expanding mandrel is transported with cylinder
It is dynamic so that it unclamps with internal expanding chuck or is interference fitted from and has reached the purpose of release and Clamp blocks.
Clamped condition：Cylinder drives internal expanding mandrel to move downward, and by cone match, makes internal expanding chuck spreading, clamps zero
Part；
Releasing orientation：Cylinder promotes internal expanding mandrel to move upwards, and internal expanding chuck leans on the elasticity of itself, replys shape during reconditioning
State, unclamp part.
The base baseplane of reconditioning lower base 2 is needed before use, it is desirable to flatness 0.005mm, 0.4 μm of roughness Ra, reconditioning
Later, cylinder certain pressure is given, frock is in clamped condition, now reconditioning internal expanding chuck contacts surface with inner bore of part,
Circularity 0.003mm is sought, with base baseplane perpendicularity 0.005mm, 0.4 μm of roughness Ra, can now ensure the bounce of part
It is required that.
It the above is only the concrete application example of the present invention, protection scope of the present invention be not limited in any way.All uses
Equivalent transformation or equivalent replacement and the technical scheme formed, all fall within rights protection scope of the present invention.
