First scalloped recess (2a) bottom land of each described grip block (2) has axial installing hole, axial bolt (3) is installed in each axial installing hole, thus grip block (2) is fixed on the corresponding claw of scroll chuck (1) by axial bolt (3); Second scalloped recess (2b) bottom land of each described grip block (2) circumferentially has at least two axial blind holes (2b '), this axial blind hole is heavy stand hole, and in each axial blind hole (2b '), a discharging spring (4) is housed; The left part of described discharging spring (4) is installed with a packing ring (5), and this packing ring is fixed in the macropore section of described axial blind hole (2d), and the right part of discharging spring (4) is exposed division.
Adopt technique scheme, the present invention is by the bottom land axial location thin-walled gear ring of the second scalloped recess (2b), the periphery of the cell wall clamping thin-walled gear ring of the second scalloped recess (2b), so just can prevent gear ring from deforming because of unbalance stress well, thus ensure the machining accuracy of gear ring, after processing, gear ring is by discharging spring ejection, thus realize automatic discharging, and structure of the present invention is simple, easy to implement, there is good practicality, also can promote the use to the similar thin-wall part of other versions of clamping.In addition, each described grip block (2) is fixed by the corresponding claw of at least two axial bolt (3) with scroll chuck (1), and axial bolt (3) is arranged on the bottom land of the first scalloped recess (2a), so just can fixed clamp block (2) securely, make grip block (2) uniform force, can not be shifted because of unbalance stress.Meanwhile, the depth design of the second scalloped recess (2b) is moderate, effectively can locate the thin-walled gear ring of different-thickness, thus expand the scope of application of the present invention.
As preferably, every block grip block (2) is provided with three discharging springs (4), and the extending part of this discharging spring is in the left side of grip block (2) right side.
Beneficial effect: the present invention is by the bottom land axial location thin-walled gear ring of the second scalloped recess, the periphery of the cell wall clamping thin-walled gear ring of the second scalloped recess, so just can prevent gear ring from deforming because of unbalance stress well, thus ensureing the machining accuracy of gear ring, after processing, gear ring is by discharging spring ejection, thus realizes automatic discharging, and structure of the present invention is simple, easy to implement, there is good practicality, also can promote the use to the similar thin-wall part of other versions of clamping.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, 2, a kind of thin-walled gear ring inner hole refined turner dress, is formed primarily of scroll chuck 1 grip block 2 axial bolt 3 discharging spring 4 and packing ring 5.Wherein, scroll chuck 1 adopts outsourcing piece, and its structure & working mechanism repeats no more.Three right surfaces of claw of scroll chuck 1 are installed with a fan-shaped grip block 2 respectively, the right surface of each grip block 2 has the first scalloped recess 2a and the second scalloped recess 2b vertically, wherein the second scalloped recess 2b is positioned at the outside of the first scalloped recess 2a, and is located at the right of the first scalloped recess 2a.Meanwhile, the depth H of the second scalloped recess 2b is 0.5-3mm, and can more preferably 1,1.5,2 and 2.5mm, and the radius of the second scalloped recess 2b is 20-30mm.In addition, the radius of the first scalloped recess 2a is 15-19mm.After three claws of scroll chuck 1 are drawn close, three grip blocks 2 form a complete disk, and the first scalloped recess 2a on three grip blocks 2 and the second scalloped recess 2b forms a cannelure completed respectively, and the axial line of cannelure and disk and scroll chuck 1 is on same axis.The bottom land of the second scalloped recess 2b is used for axial location thin-walled gear ring, and the cell wall of the second scalloped recess 2b is for clamping the periphery of thin-walled gear ring, and the surface roughness of the second scalloped recess 2b cell wall is 0.8mm.
Can find out from Fig. 1,2, the first scalloped recess 2a bottom land of each grip block 2 has axial installing hole, is provided with axial bolt 3, thus is fixed on the corresponding claw of scroll chuck 1 by grip block 2 by axial bolt 3 in each axial installing hole.Second scalloped recess 2b bottom land of each grip block 2 circumferentially has at least two axial blind hole 2b ', and this axial blind hole 2b ' is heavy stand hole, and in each axial blind hole 2b ', a discharging spring 4 is housed.In the present case, every block grip block 2 is provided with three discharging springs 4, and the extending part of this discharging spring is in the left side of grip block 2 right side.Meanwhile, the left part of every root discharging spring 4 is installed with a packing ring 5, and this packing ring 5 is fixed in the macropore section of described axial blind hole 2d, and the right part of discharging spring 4 is exposed division.Meanwhile, the exposed division axial length of discharging spring 4 right part is 1-3mm, and design is to ensure that elastic force is moderate like this, can ensure reliably discharging, can reduce again resistance during clamping workpiece.The effect of packing ring 5 is discharging springs 4, prevents discharging spring 4 from deviating from from axial blind hole 2b '.
