Background
In the machining industry, the inner gear machining method is generally adopted, wherein a blank is clamped by a pressure plate, and an inner hole and an end face are aligned. To obtain a high-precision internal gear, the part needs to be aligned for many times, the coaxiality of an inner hole of the part and the verticality of an end face are ensured, and the labor intensity of workers and the processing period of the part are increased invisibly.
At present, when a single-piece small-batch internal gear is machined, a cushion block positioning and pressing plate pressing mode is generally adopted, and an inner hole and an end face are aligned by using a dial indicator. The clamping and positioning method is easy to generate positioning errors, and the reference circle of the gear after gear shaping generates errors on the concentricity of the inner hole, so that the radial precision of the gear is reduced. Meanwhile, due to the fact that eccentricity is caused by gaps in part clamping, derived errors such as tooth profile, tooth direction and cycle of a gear can be affected during gear shaping, and therefore the precision of the whole gear after gear shaping is low.

Preferably, the tensioning device comprises a pull rod, a pull rod nut and a connecting rod, the pull rod is connected with the connecting rod through the pull rod nut, the cross section of the connecting rod is T-shaped, and the connecting rod is abutted to the inner side wall of the base.
Preferably, the positioning ring is fixedly connected with the supporting disc through a second screw.
Preferably, a spacer bush is arranged between the connecting rod and the supporting disc.
Preferably, a shunt cone is arranged at the central position of the supporting disk, and an oil outlet is arranged between the supporting disk and the chuck base.
The utility model discloses at least, include following beneficial effect:
the clamp finally extrudes the collet chuck to clamp a workpiece through the pull rod pulled down by the cylinder or the hydraulic cylinder, the collet chuck provides uniform circumferential force, and clamping efficiency can be guaranteed and clamping precision can be improved.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

Detailed Description
The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.
It should be noted that, in the description of the present invention, the terms "above", "inside", "away", "one side", "between", "center position", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of description of the present invention and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be configured and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
As shown in fig. 1, the utility model provides a drop-down formula gear shaping anchor clamps, include: fix cylindrical base 4 on numerical control gear shaping machine workstation, through tang cooperation location install in proper order the supporting disk 7 and the chuck seat 8 of 4 tops of base, install the inboard collet chuck 9 of chuck seat 8, install the inboard position circle 10 of collet chuck 9 and fixing the supporting disk 7 deviates from the straining device of collet chuck 9 one side, collet chuck 9 the supporting disk 7 straining device passes through first screw 5 through connection.
After the hole sites of the base 4, the supporting plate 7 and the chuck seat 8 are aligned, the supporting plate 7 and the chuck seat 8 are locked on the base 4 through a third screw 6; a second screw is penetrated from the lower part of the supporting disc 7 to lock the positioning ring 10 on the supporting disc 7, and the end face of the positioning ring 10 is a clamping positioning plane for aligning a processing plane on the gear shaping machine; the spring chuck 9 is positioned between the positioning ring 10 and the chuck seat 8, the spring chuck 9 is an inner cylindrical surface for centering a rotation center on the gear shaper, the spring chuck 9 and the tension device are respectively positioned at two sides of the supporting plate 7, and the spring chuck 9, the supporting plate 7 and the tension device are in through connection through a first screw 5;
