Description
Technical field
The present invention relates to a kind of grinder automatic clamping chuck, especially a kind of small-sized handware grinder automatic clamping chuck.
Background technology
The effect of small-sized handware grinder makes after fixing small workpiece clamping, the surface to workpiece or point by bistrique
Angle is ground, to complete the moulding to miniature workpiece and lapped face is made to have higher finish.But due to current
Grinder is generally fixed workpiece by the way of scroll chuck, causes grinder can not be to the work of some unconventional moulding
Part is fixed, and can also cause the three-jaw of chuck can not be simultaneously to work in non-symmetrical parts such as fixed oval-shaped piece, eccentric pipes
Part formation fits closely, to reduce clamping stability of the grinder to workpiece.Further, since conventional grinder can not be right
Workpiece after clamping carries out rotation and the offset at angle of inclination, and grinder is caused to be needed in the multiple process of lapping to a workpiece
Workpiece is positioned repeatedly, when workpiece need when obliquity grind also can only by change workpiece clamping position come
It completes, this positioning and regulative mode can not only reduce the precision of workpiece after grinding, and tilt clamping and can also reduce grinding
The clamping stability of machine, to make workpiece occur the case where stress is deviated or fallen in process of lapping, safety is poor.Therefore,
Existing grinder has that the scope of application is small, positioning accuracy is low and clamping stability difference to the installation way of workpiece.

The present invention is further illustrated with reference to the accompanying drawings and examples, but be not intended as to the present invention limit according to
According to.
Embodiment.A kind of small-sized handware grinder automatic clamping chuck is constituted as shown in Figure 1, including supporting rack 1, support
It is connected with intermediate swing type cylinder 3 through copper sheathing 2 on frame 1, the swinging axle outside of intermediate 3 side of swing type cylinder is through multiple screws 4
It is connected with rotate gear 5, the engagement of 5 lower end of rotate gear is connected with driving gear 6, and 6 inside of driving gear is connected with driving motor
7, telescopic rod 8 is connected at the projecting shaft of intermediate swing type cylinder 3,8 outside of telescopic rod is equipped with mounting bracket 9,8 end of telescopic rod warp
It is threaded with head 10,10 side wall of head is equipped with lock-screw, and 10 outside of head is evenly distributed with multiple installation steps
101,101 outside of each installation step is rotatably connected to head rod 11, and 11 end of head rod is connected through axis pin 12
There are the second connecting rod 13,13 end of the second connecting rod to be connected with clamping plate 14,14 one end of clamping plate is equipped with arc and clamps face 141,
Arc clamps and is evenly distributed with several clamping circular grooves 142 on face 141, and 14 other end of clamping plate is rotatably connected on mounting bracket 9, institute
The butterfly spring 15 that 12 middle part of axis pin is equipped between head rod 11 and the second connecting rod 13 is stated, 12 both ends of axis pin are equipped with
It is separately fixed at the electromagnet 16 in 13 outside of head rod 11 and the second connecting rod, the head rod 11 is far from electromagnet
Multiple arcs slot 111, the side of the second connecting rod 13 far from 16 side of electromagnet is distributed on the side wall of 16 sides in a ring
Wall is equipped with the multiple arcs protrusion 131 coordinated with arc groove 111.
Rotate gear 5 is connected through four screws 4 on the outside of the swinging axle of the intermediate swing type cylinder 3, four screws 4 are in just
The rectangular end for being distributed in swinging axle.
The gear ratio of the rotate gear 5 and driving gear 6 is 3：1.
Second connecting rod, 13 end connects axis pin 12 through strip hole 132.
It is equipped with cover board 17 between the rotate gear 5 and the swinging axle of intermediate swing type cylinder 3.
The operation principle of the present invention：The present invention is fixed on through supporting rack 1 on grinder, when workpiece needs to clamp, user
Between workpiece is first placed on each clamping plate 14, and the relative angle of head rod 11 and the second connecting rod 13 is adjusted, makes folder
The arc of tight plate 14 clamps face 141 and can be tightly attached on the side wall of workpiece；Head rod 11 and the second connecting rod 13 are being adjusted
Electromagnet 16 is closed when angle, and arc groove 111 and arc convex 131 are mutual under the action of butterfly spring 15 at this time
Separation, makes to be freely rotated between head rod 11 and the second connecting rod 13；Head rod 11 and the second connecting rod 13
Its adjustable range can also be extended by strip hole 132 when adjusting angle, make clamping plate 14 that there is the gripping angle of bigger, and
