The side of one clamping position 301.In the present embodiment, one of clamping position 301 is close to grinding cutter 2, and another is filled
The side for pressing from both sides position 301 is exactly piece installing mechanism 5.Piece installing mechanism 5 has along the central axial direction of the clamping position 301
The dynamic sleeve 501 of return.That is, sleeve 501 can be actuated to close to or away from clamping position 301.When need into
When the clamping of row workpiece 6, the utility model is with regard to control sleeve 501 close to clamping position 301；After clamping is completed, this reality
With it is new with regard to control sleeve 501 away from clamping position 301.In one embodiment, except sleeve 501 itself be capable of it is overall into
Row is mobile outer, and the inner side of sleeve 501 is provided with the slide strips moved along the central axial direction of the clamping position 301.Workpiece 6
The inside of sleeve 501 is arranged on, to be moved inside it along the central axial direction of clamping position 301 with slide strips.Therefore,
For sleeve 501 when close to clamping position 301, slide strips are also in movement, so that workpiece 6 departs from sleeve 501, and are fixed on described
At clamping position 301.
Preferably, in order to which the smooth clamping of workpiece 1, the axis of sleeve 501 are overlapped with the central axis of clamping position 301.
To sum up, when the utility model will carry out the processing of workpiece 5, specific technological process include piece installing, processing, inloading part,
Piece installing again.
Piece installing process is as follows.5 control sleeve 501 of piece installing mechanism is close to jig main body 3.Workpiece 6 is swung in sleeve is neat
The inside of sleeve 501.Slide strips inside sleeve 501 drive workpiece 6 to be moved toward jig main body 3 (namely clamping position 301) place.
Jig main body 3 rotates under the drive of clamp shaft 4, to pass through piece installing mechanism 5 respectively, so that each of jig main body 3
Workpiece 6 is all fixed at clamping position 301.Then, 5 control sleeve 501 of piece installing mechanism is away from jig main body 3.
Process is as follows.Shaft 1 starts, to process the workpiece 6 at the clamping position 301 of grinding cutter 2.This work
After part 6 machines, clamp shaft 4 rotates, another unprocessed workpiece 6 is turned at the position of grinding cutter 2.Fixture
Driving mechanism enables to jig main body 3 to be moved horizontally along the axis direction of the shaft 1, so as to control cutting each time
Amount, cutting number, cutting precision.Therefore, after the workpiece 6 at all clamping positions 301 all machines, driving mechanism can
To control jig main body 3 to move, to adjust cutting output and cutting precision.
Inloading part and piece installing process is as follows again.After workpiece 6 machines, shaft 1 stops operating.Clamp shaft 4 rotates, so that
Obtain processing staff and unload workpiece 6 respectively.Then the workpiece 6 of generation processing is fixed to clamping position 3 again by piece installing mechanism 5
Place.
The embodiment of the utility model is explained in detail above in association with attached drawing, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, it is right in the case where not departing from the utility model principle and spirit
