Abstract
The utility model relates to the technical field of NdFeB processing, in particular to a NdFeB non-magnetic grinding clamp. The NdFeB non-magnetic grinding clamp comprises a magnetic disk and a magnetism separating plate, wherein the magnetism separating plate is attracted on the magnetic disk, a plurality of blocking bars are fixedly arranged on the magnetism separating plate, and the blocking bars are connected in an end-to-end mode to form a closes structure. The NdFeB non-magnetic grinding clamp is simple in structure, and due to the facts that the magnetism separating plate prevents products from being magnetized in processing and the products can not break away from a processing surface through multi-point locating, production efficiency and product quality are improved.
Description
Technical field
The utility model relates to the neodymium iron boron processing technique field, and particularly a kind of neodymium iron boron does not have the magnetic grinding jig.
Background technology
The development of rare earth permanent-magnetic material at present is very rapid, has obtained extensive use in a lot of fields, becomes the valuable cargo basis of up-to-date technology; Sintered NdFeB in the rare-earth permanent magnet not only has very high remanence strength, very high magnetic energy product, and have very high coercivity, this be current any permanent-magnet material can't compare.
The general grinding machine that adopts of the flatness processing of neodymium iron boron product, neodymium iron boron can stay bigger remanent magnetism by disk suction is fixing, directly causes product to produce tangible magnetic circuit in follow-up electroplating work procedure, has a strong impact on the outward appearance of product; And neodymium iron boron demagnetization effectiveness at normal temperatures is undesirable, and demagnetization can influence size and the form and position tolerance of product under the high temperature, and processing brings certain trouble to product; Therefore need improve the grinding machine processing mode, to avoid the problems referred to above to the influence of product quality.
The utility model content
The purpose of this utility model is at the defective of prior art and deficiency, provides a kind of compact conformation, easy to operate neodymium iron boron not to have the magnetic grinding jig.
For achieving the above object, the utility model is by the following technical solutions:
A kind of neodymium iron boron described in the utility model does not have the magnetic grinding jig, comprises disk and magnetic isolation plate, and described magnetic isolation plate is adsorbed on the disk, is fixed with some grades of bars on the magnetic isolation plate, the end to end composition enclosed construction of described blend stop.
Further, have some locating holes on the described blend stop, the locating hole level runs through the blend stop both sides, is spirally connected on the locating hole to be provided with fixed screw.
The utility model beneficial effect is: the utility model is simple in structure, prevents that by magnetic isolation plate the product work in-process is magnetized, and adopts multipoint positioning to make product can not break away from machined surface in processing, has improved production efficiency and product quality.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
Among the figure:
1, disk; 2, magnetic isolation plate; 3, blend stop; 4, emery wheel;
31, fixed screw; 32, locating hole.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of neodymium iron boron described in the utility model does not have the magnetic grinding jig, comprises disk 1 and magnetic isolation plate 2, and described magnetic isolation plate 2 is adsorbed on the disk 1, is fixed with some grades of bars 3 on the magnetic isolation plate 2, described blend stop 3 end to end composition enclosed constructions; Particularly, the influence of magnetizing that has completely cut off 1 pair of workpiece of disk after above-mentioned magnetic isolation plate 2 is fixing with disk 1 absorption, processing plane is formed with magnetic isolation plate 2 in some blend stops 3 inboards.
Have some locating holes 32 on the described blend stop 3, locating hole 32 levels run through blend stop 3 both sides, and being spirally connected on the locating hole 32 is provided with fixed screw 31.After piling workpiece in the machined surface scope that some blend stops 3 are formed, by some fixed screws 31 fixation workpieces on the blend stop 3 and the horizontal relative position of disk 1.
Operation principle: workpiece is placed on the anchor clamps, after being paved with blend stop 3 scopes of whole anchor clamps, fasten screw 31, when 4 pairs of workpiece surfaces of emery wheel add man-hour, disk 1 reverse rotation thereupon, because magnetic isolation plate 2 has cut off the magnetic force influence of 1 pair of workpiece of disk, the product surface after the grinding can not produce the magnetic circuit phenomenon.
The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
