Abstract
The utility model provides a circular-ring-shaped neodymium iron boron magnet edge portion polishing clamp and aims at solving the problem that a clamp special for edge portion polishing of an annular neodymium iron boron magnet does not exist. The circular-ring-shaped neodymium iron boron magnet edge portion polishing clamp comprises a disc-shaped base support and is characterized in that a rotary shaft is arranged in the middle of the disc-shaped base support and connected with a drive device, a spring seat is connected above the rotary shaft and is circular-ring-shaped, a group of springs is installed inside the spring seat along the radial direction, each spring is connected with an arc-shaped support block, and an upper press cover is arranged above the spring seat. The circular-ring-shaped neodymium iron boron magnet edge portion polishing clamp is an auxiliary matched facility used in the polishing process of the annular neodymium iron boron magnet.
Description
Technical field:
The utility model relates to a kind of anchor clamps, is specifically related to a kind of annular neodymium iron boron magnetic body limit portion polishing anchor clamps.
Background technology:
High-performance is radially oriented to be widely used the ring-shaped sintered neodymium-iron-boron permanent magnet because it has, common processing method is at first to carry out powder compaction, in powder compaction process, at first blank is pressed into cylindrical product, adopt boring then, draw hole or wire cutting method reprocessing endoporus, carry out the polishing of limit portion after the processing, because neodymium iron boron magnetic body is hard and crisp, the stability that clamps in the limit portion bruting process directly influences effect and the yield rate of limit portion polishing, does not also have to carry out at the annular neodymium iron boron magnetic body specially the anchor clamps of limit portion polishing at present.
Summary of the invention:
The purpose of this utility model is that the problem at above-mentioned existence provides a kind of annular neodymium iron boron magnetic body limit portion polishing anchor clamps, can be stablized clamping by neodymium iron boron magnetic body in bruting process, and clamping force is good.
Above-mentioned purpose realizes by following technical scheme:
Annular neodymium iron boron magnetic body limit portion polishing anchor clamps, comprise the disk-shaped bottom bearing, be provided with turning cylinder in the middle of the described disk-shaped bottom bearing, described turning cylinder connects drive unit, described turning cylinder top connects a spring base, and described spring base is annular, and one group of spring is radially installed in described spring base the inside, each described spring connects the arc back-up block, and described spring base top is provided with upper press cover.
Described annular neodymium iron boron magnetic body limit portion polishing anchor clamps, described spring is no less than 3.
Described annular neodymium iron boron magnetic body limit portion polishing anchor clamps, the side towards described spring base on described disk-shaped bottom bearing and the described upper press cover is respectively arranged with one group of groove, and ball is installed in described groove the inside.
Described annular neodymium iron boron magnetic body limit portion polishing anchor clamps, described groove is most ball-types, described ball is embedded in described groove the inside.
Beneficial effect:
1. the utility model adopts the elastic force of one group of spring with the annulus chucking of annular neodymium iron boron magnetic body from the middle part, at one group of spring under the effect of circumferential elastic force, avoided the annular neodymium iron boron magnetic body that phenomenons such as skew take place, thereby drive spring base by turning cylinder and drive the rotation of annular neodymium iron boron magnetic body, carry out limit portion uniform grinding at the polishing machine, it is effective to polish.And under the elastic force effect of spring, the utility model is applicable to the annular neodymium iron boron magnetic body that clamps different size, and is applied widely.
2. evenly number of springs of the present utility model is no less than 3 for annular neodymium iron boron magnetic body in the feasible process that clamps is stressed, and evenly distributes along circumference in the groove the inside of annular spring base.
3. the utility model side towards described spring base on disk-shaped bottom bearing and described upper press cover is respectively arranged with one group of groove, ball is installed in described groove the inside, avoid rigid element up and down that neodymium iron boron magnetic body is caused damage when clamping the annular neodymium iron boron magnetic body, and it is slick and sly in rotating process, avoid blocking, polishing is even, and it is effective to polish.
4. come off for fear of ball, groove of the present utility model is set to most ball-types, and the diameter of ball should be slightly less than the diameter of most ball-type grooves in practical operation, guarantees the outstanding groove plane of ball when avoiding ball to come off, and plays effect preferably.
