Description
Technical field
The utility model relates to the frock clamp that uses in a kind of machine-building, relates in particular to a kind of anchor clamps that are used for the unsteady shaving of gear.
Background technology
Be used for the anchor clamps of the unsteady shaving of gear at present, comprise positioning core axle and gland, an end of positioning core axle is provided with axial axis hole; The other end of positioning core axle is provided with centre hole, and an end of gland is inserted in the axis hole of positioning core axle, and the other end of gland is provided with centre hole; The middle part of gland is provided with ring flange, is connected through screw between the axis hole end end face of positioning core axle and the ring flange of gland, thereby realizes the circumferential location between positioning core axle and the gland; Because positioning core axle and gland need keep mutual circumferential movement when assembling; Just will inevitably there be the fit-up gap, simultaneously because there is roundness tolerance respectively in the cross section of positioning core axle, gland, so positioning core axle and gland circumferential relative fixed position that make the anchor clamps axiality reach the best of meeting existence behind assembly; To reduce the radial-play of anchor clamps; In order to make anchor clamps at every turn when the clamping gear, the positioning core axle of anchor clamps and gland all are in best the relative circumferential position, just need this position relative fixed be got off.
The utility model content
The technical problem that the utility model solves is: a kind of anchor clamps that are used for the unsteady shaving of gear are provided, can reduce the axial float of anchor clamps.
The technical scheme of the utility model is: a kind of anchor clamps that are used for the unsteady shaving of gear, comprise positioning core axle and gland, and an end of said positioning core axle is provided with axial axis hole; The other end of positioning core axle is provided with centre hole, and an end of said gland is inserted in the axis hole of positioning core axle, and the other end of gland is provided with centre hole; The middle part of gland is provided with ring flange; It is characterized in that the edge of the axis hole end end face of said positioning core axle is provided with some breach, it is on first circumference in the center of circle that said breach is equally spaced at the center with the axis hole of positioning core axle; The ring flange of said gland is provided with some screwed holes; The center that said screwed hole is distributed in the ring flange of gland is that the diameter of said second circumference equals the diameter of said first circumference on second circumference in the center of circle, is installed with a screw simultaneously at least one screwed hole and at least one breach.
On the outer wall circumference of said positioning core axle, said gland respectively milling flat side is arranged, two flat orientation are on the cocurrent and parallel plane.
Said two flat sides are respectively near an end that is provided with centre hole.
The edge of the axis hole end end face of said positioning core axle is provided with 6 breach, and the ring flange of said gland is provided with 4 screwed holes, and these 4 screwed holes are equally spaced on central angle is 225 ° circular arc.
The beneficial effect of the utility model is: the utility model in use; Through positioning of rotating mandrel and gland; Determine a minimum circumferential position of positioning core axle and gland assembling back radial-play, can simultaneously be installed with into screw at least one screwed hole and at least one breach this moment, through screw the circumferential position of positioning core axle and gland fixed; Therefore reduce the radial-play of the anchor clamps of positioning core axle and gland assembling back formation, improved clamping precision and gear shaving precision.
Since on the outer wall circumference of said positioning core axle, said gland respectively milling flat side is arranged; Two flat orientation are on the cocurrent and parallel plane; During the different gear of therefore each clamping, only need to guarantee that two flat sides on the cocurrent and parallel plane, just can guarantee to be between positioning core axle and the gland circumferential position of the best; Simple to operate, quick, improved the operating efficiency of clamping.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Referring to Fig. 1～Fig. 7, a kind of anchor clamps that are used for the unsteady shaving of gear comprise positioning core axle 1 and gland 2; One end of positioning core axle 1 is provided with axial axis hole 1a; The other end of positioning core axle 1 is provided with centre hole 1b, and the middle part of gland 2 is provided with ring flange 2a, and an end of gland 2 is inserted among the axis hole 1a of positioning core axle 1; The other end of gland 2 is provided with centre hole 2b; The edge of the axis hole end end face of positioning core axle 1 is provided with 6 breach 1c, and it is on first circumference in the center of circle that 6 breach 1c are equally spaced at the center with the axis hole 1a of positioning core axle 1, and the ring flange 2a of gland 2 is provided with 4 screwed hole 2a '; The center that 4 screwed hole 2a ' are distributed in the ring flange 2a of gland 2 is on second circumference in the center of circle; Be equally spaced central angle at second circumference of 4 screwed hole 2a ' is that the diameter of second circumference equals the diameter of first circumference, is installed with a screw 3 simultaneously among at least one the screwed hole 2a ' on the ring flange 2a of gland 2 and at least one the breach 1c on the positioning core axle 1 on 225 ° the circular arc; In the present embodiment, be installed with a screw simultaneously in a screwed hole on the ring flange of gland and the breach on the positioning core axle.On the outer wall circumference of positioning core axle 1, gland 2 respectively milling flat side is arranged; Two flat orientation are on the cocurrent and parallel plane; Flat side 1d on the positioning core axle 1 is provided with the end of centre hole 1b near positioning core axle 1, and the flat side 2c on the gland 2 is provided with the end of centre hole 2b near gland 2.
