Abstract
The invention discloses a high-precision centreless grinding manufacturing method of shaft element with axial groove, which comprises the following steps: bonding a cylindrical and high-precision grinding base block at two ends of the shaft element; opening a 'V' shaped groove on the surface of chassis and a straight groove in the middle of the groove; making the depth H of the straight groove deeper than 'V' shaped groove and groove breadth B as one fourth of the shaft length; fixing the axial locating pin in the 'V' shaped groove with distance C between end surface and the straight groove as two thirds of the height of grinding datum block; placing the grinding datum block in the 'V' shaped groove to next to the axial locating pin tightly; placing the axial groove element in the other end of the 'V' shaped groove; moving the end surface to approach the grinding datum end surface A to discharge glue to two end spaces rapidly; exerting axial force to bond end surface and grinding datum block end surface A; adopting outer diameter of grinding datum block as datum to do high-precision centreless abrasion for shaft element and abrasion datum block; removing the datum block at two ends after finishing the abrasion.
Description
Technical field
The invention belongs to the Grinding Technology field, especially a kind of axially grooved axial workpiece high-accuracy centerless grinding method for processing.
Background technology
Cylindrical spring pin as shown in Figure 1, 2, common processing technology is: the correct grinding that carries out external diameter earlier reaches technological requirement, adopts the method for Wire EDM to process narrow groove then.Because specific (special) requirements, present processing technology is: roughly grind external diameter earlier, then line cuts out narrow groove, finish grindes external diameter at last again.
When after cutting out narrow groove, carrying out the correct grinding of external diameter, normally adopt the collet clamping workpiece, on universal grinding machine external, adopt the method processing of centering grinding, and can not adopt high accuracy centerless grinding machine to carry out high-accuracy centerless grinding.
Because after adopting the method grinding external diameter of centerless grinding, the external diameter cross section is not circular, but peach shape as shown in Figure 3.
Such shape can't satisfy the designing requirement and the instructions for use of product at all.
Summary of the invention
In order to overcome the weak point that above-mentioned technology is brought, the invention provides a kind of axially grooved axial workpiece high-accuracy centerless grinding method for processing, utilize this processing method.
In order to realize the foregoing invention purpose, the present invention adopts following technical scheme:
Described axially grooved axial workpiece high-accuracy centerless grinding method for processing is to pass through each bonding high-precision grinding reference block of bonding jig at axially grooved axial workpiece two ends, and reference block is cylindrical, and its external diameter is identical with the external diameter of axial workpiece; One " V " type groove left by bonding jig on plane on its base, open a straight trough on the vertical direction in the middle of " V " type slot length, and the groove depth H of straight trough is deeper than " V " type groove depth, and groove width B is about 1/4 of axial workpiece length; The axial location pin is fixed in " V " type groove, makes the distance C of its tip to face distance straight trough be about 2/3 of grinding reference block height; The grinding reference block is placed in " V " type groove, be close to the axial location pin, then axially grooved axial workpiece is placed on the other end of " V " type groove, moving makes its end face near grinding reference block end face A, to between both ends of the surface, put glue fast, applying axial force makes its end face and grinding reference block end face A bonding, centering is bonding exactly for grinding reference block and axially grooved axial workpiece like this, be benchmark with grinding reference block external diameter then, axial workpiece and grinding reference block are carried out high-accuracy centerless grinding together, remove the two ends reference block after grinding finishes and get final product.
Owing to adopted technical scheme as mentioned above, the present invention has following good effect:
1, solved the peach shape problem that axially grooved axial workpiece centerless grinding cylindrical produces;
2, axially grooved axial workpiece centerless grinding cylindrical has obtained very high form accuracy, and circularity has reached 0.8 μ m;
3, be particularly suitable for the accurate grinding of small lot, high accuracy, axial axial workpiece external diameter of having slotted.

The specific embodiment
As shown in Figure 5: axially grooved axial workpiece high-accuracy centerless grinding method for processing of the present invention is by each bonding high-precision grinding reference block of bonding jig at axially grooved axial workpiece two ends, reference block is cylindrical, and its external diameter is identical with the external diameter of axial workpiece; One " V " type groove left by bonding jig on plane on its base 1, open a straight trough on the vertical direction in the middle of " V " type slot length, and the groove depth H of straight trough is deeper than " V " type groove depth, and groove width B is about 1/4 of axial workpiece length; Axial location pin 2 is fixed in " V " type groove, makes the distance C of its tip to face distance straight trough be about 2/3 of grinding reference block height; Grinding reference block 3 is placed in " V " type groove, be close to axial location pin 2, then axially grooved axial workpiece 4 is placed on the other end of " V " type groove, moving makes its end face near grinding reference block end face A, to between both ends of the surface, put glue fast, applying axial force makes its end face and grinding reference block end face A bonding, centering is bonding exactly for grinding reference block and axially grooved axial workpiece like this, be benchmark with grinding reference block external diameter then, axial workpiece and grinding reference block are carried out high-accuracy centerless grinding together, remove the two ends reference block after grinding finishes and get final product
Specific implementation process is as follows when carrying out cylindrical centerless type grinding according to above-mentioned processing method:
At first design grinding reference block 3: the reference block external diameter is identical with the axial workpiece external diameter, highly is convenient to bondingly, and its external diameter and both ends of the surface are carried out Precision Machining;
Base 1 is set: open one " V " type groove thereon on the plane, open a straight trough on the vertical direction of " V " type groove, the groove depth H of straight trough is deeper than " V " type groove depth, and groove width B is about 1/4 of axial workpiece length;
Axial location pin 2 is set: be fixed in " V " type groove, make the distance C of its tip to face distance straight trough be about 2/3 of grinding reference block height;
Grinding reference block 3 is placed in " V " type groove, be close to axial location pin 2, then axially grooved axial workpiece 4 is placed on the other end of " V " type groove, moving makes its end face near grinding reference block end face A, to between both ends of the surface, put glue fast, apply axial force and make its end face and grinding reference block end face A bonding, centering is bonding exactly for grinding reference block and axially grooved axial workpiece like this.
After both ends of the surface are all bonding,, carry out the centerless grinding of axially grooved axial workpiece 4 with grinding reference block 3 location.
External diameter removes grinding reference block 3 after finishing processing, promptly reaches the desired precision quality of axial workpiece external diameter.
