Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustration and not for limitation of the present invention.

As shown in fig. 1-5, a neodymium iron boron permanent magnet section is polished and is used fixed frock, including clamping jaw 1 that is used for the bar-shaped permanent magnet of centre gripping, the direction of motion's that is used for guiding clamping jaw 1 direction of motion guiding disk 2, be used for driving clamping jaw 1 driving motor 10 of motion and be used for fixed direction dish 2 and driving motor 10's mount 3, clamping jaw 1 sliding connection is on direction dish 2, driving motor 10 output shaft fixed connection direction dish 2. Through set up three-jaw anchor clamps on positioning disk 2, it is fixed to accomplish the centre gripping of frock to bar-shaped neodymium iron boron permanent magnet to realize the effect in automatic centre gripping location axle center, motor drive is fixed fast, avoids the adjustment repeatedly to the holder, improves production efficiency, alleviates artifical burden, reduces the requirement to the artificial experience, reduces the manufacturing cost of enterprise.

Further, three clamping jaws 1 are circumferentially arrayed around the axis direction of the rotating shaft of the driving motor 10. Three clamping jaw 1 evenly distributed is in the periphery of driving motor 10 output shaft axis, and when driving motor 10 drove the positioning disk 2 and rotates, three clamping jaw 1 synchronous rotation to make the permanent magnet axis of treating processing keep unanimous with driving motor 10 output shaft axis, realize the effect that the three-jaw is from feeling relieved, simple structure, and three point construction, make the mode of grasping and supporting more firm.

Further, each clamping jaw 1 is provided with an arc-shaped groove for clamping the rod-shaped permanent magnet at one side close to the rotating axis. The arc-shaped groove enables the clamping jaw 1 to be more attached to the outer surface of the rod-shaped permanent magnet, the firm static friction force is increased, and the quality problem caused by shaking when the slicing and polishing are avoided.

Further, the guide disc 2 comprises a linear guide disc 4 and a curved guide disc 5, the linear guide disc 4 is fixed on the fixing frame 3, and the curved guide disc 5 is fixed at the output end of the driving motor 10. The reciprocating motion of the clamping jaw 1 between the axis and the periphery of the guide disc 2 is realized through the relative rotation motion of the linear guide disc 4 and the curve guide disc 5.

Further, a linear sliding groove 6 which radiates outwards along the axis of the rotating shaft of the driving motor 10 is arranged on the linear guide disc 4 corresponding to the clamping jaw 1. The linear sliding groove 6 ensures that the clamping jaw 1 can only move along the radial direction of the rod-shaped permanent magnet, thereby being beneficial to grasping permanent magnets with different sizes and increasing the universality of the clamp.

Furthermore, a curved chute 7 radiating outwards along the axis of the rotating shaft of the driving motor 10 is arranged on the curved guide disc 5 corresponding to the clamping jaw 1. The orientation of the curve sliding groove 7 is gently extended from the axis to the outer periphery, so that the clamping jaw 1 smoothly reciprocates from the axis to the outer periphery in the curve sliding groove 7 along with the rotation of the curve guide disc 5, and the radial length of the curve sliding groove 7 along the curve guide disc 5 is the same as that of the straight sliding groove 6.

Further, the diameter of the linear guide disk 4 is larger than that of the curved guide disk 5. The diameter of straight line guiding disk 4 is great, can make straight line guiding disk 4 have can with the fixed surplus space mutually of bottom mount 3, avoid interfering the rotation of curve guiding disk 5 because of the two fixed connection, and further, straight line guiding

disk

4 and 3 interval fixed connection of mount, straight line guiding disk 4 is greater than the vertical height of curve guiding disk 5 with 3 interval distance of mount, avoids influencing the rotation of curve guiding disk 5 equally.

Further, the linear guide plate 4 is fixed to the fixing frame 3 by a bolt fastener 8. Bolt fastener 8 low cost, and ability quick adjustment fixed height, easy dismounting is convenient for other parts in the later maintenance of being convenient for.

Furthermore, the bottom of the fixing frame 3 extends outwards to form a flange, and a plurality of fixing holes 9 for fixing the fixing frame 3 on the equipment are formed on the flange. In fasteners such as accessible bolt stretched into fixed orifices 9, and then be fixed in whole fixed frock and treat the equipment of processing, general structural component makes things convenient for the dismouting replacement, saves enterprise equipment cost.

Further, 1 bottom of clamping jaw is equipped with the limiting plate that is used for preventing clamping jaw 1 to break away from guiding disc 2.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, i.e. the present invention is intended to cover all equivalent variations and modifications within the scope of the present invention.
