Abstract
The invention provides a water-cooled supporting and fixing device for grinding planes of circular neodymium-iron-boron magnets. The water-cooled supporting and fixing device aims to solve problems that the Curie temperature of a neodymium-iron-boron magnet is extremely low, is about 312 DEG C and is poor in stability, the neodymium-iron-boron magnet is restricted from being ground at a high temperature, the magnetism of the neodymium-iron-boron magnet can fade if the temperature of a workpiece is increased during grinding, and service functions and effects of the neodymium-iron-boron magnet are affected. The water-cooled supporting and fixing device comprises a disc-shaped bottom support. A cavity is arranged inside the disc-shaped bottom support and is respectively connected with a cooling water inlet tube and a cooling water outlet tube, both the cooling water inlet tube and the cooling water outlet tube are connected with a cold water tank, a spring seat is arranged in the middle of the disc-shaped bottom support, is circular and is provided with a groove, a group of springs is radially mounted inside the spring seat, and each spring is connected with an arc-shaped supporting block. The water-cooled supporting and fixing device is auxiliary assorted equipment used in circular neodymium-iron-boron magnet grinding procedures.
Description
Technical field:
The present invention relates to a kind of anchor clamps, be specifically related to a kind of water-cooled annular neodymium iron boron magnetic body plane polishing supporting adn fixing device.
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, polish after the processing, because the Curie temperature of neodymium iron boron magnetic body is very low, about 312 ℃, temperature stability is poor, limited under higher temperature and polished, if cause the workpiece temperature height in the process of polishing, then can cause the magnetic of neodymium iron boron magnetic body to disappear, influence its function of use effect.Particularly at the annular neodymium iron boron magnetic body of thinner (thickness is below 3mm), in the process of polishing, very easily cause workpiece temperature to raise.
Summary of the invention:
The objective of the invention is provides a kind of water-cooled annular neodymium iron boron magnetic body plane polishing supporting adn fixing device at the problem of above-mentioned existence, can avoid the too fast rising of neodymium iron boron magnetic body temperature in bruting process, guarantees that the magnetic of neodymium iron boron magnetic body is not affected.
Above-mentioned purpose realizes by following technical scheme:
Water-cooled annular neodymium iron boron magnetic body plane polishing supporting adn fixing device, comprise the disk-shaped bottom bearing, described disk-shaped bottom bearing inside has cavity, described cavity connects cooling water inlet pipe and cooling water outlet pipe respectively, described cooling water inlet pipe all is connected with cold water storage cistern with described cooling water outlet pipe, be provided with spring base in the middle of the described disk-shaped bottom bearing, described spring base is the annular with groove, one group of spring is radially installed in described spring base the inside, and each described spring connects the arc back-up block.
Described water-cooled annular neodymium iron boron magnetic body plane polishing supporting adn fixing device, described spring is no less than 3.
Beneficial effect:
1. the present invention adopts circulating water that support is cooled off, and by support the annular neodymium iron boron magnetic body of polishing is cooled off again, has avoided waiting to polish the annular neodymium iron boron magnetic body because the generation of the too high phenomenons such as demagnetization that cause of temperature.
2. the present invention adopts the elastic force of one group of spring that the annulus of annular neodymium iron boron magnetic body from the middle part tightened, and under the effect of circumferential elastic force, has avoided the annular neodymium iron boron magnetic body that phenomenons such as skew take place at one group of spring, clamps effective.And under the elastic force effect of spring, the present invention is applicable to the annular neodymium iron boron magnetic body that clamps different size, and is applied widely.
3. evenly number of springs of the present invention 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.
Description of drawings:
Fig. 1 is structural representation of the present invention.
Among the figure: 1, disk-shaped bottom bearing, 2, cavity, 3, cooling water inlet pipe, 4, cooling water outlet pipe, 5, cold water storage cistern, 6, spring base, 7, spring, 8, the arc back-up block, 9, the annular neodymium iron boron magnetic body of waiting to polish.
The specific embodiment:
Embodiment 1:
As shown in Figure 1: water-cooled annular neodymium iron boron magnetic body of the present invention plane polishing supporting adn fixing device, comprise disk-shaped bottom bearing 1, described disk-shaped bottom bearing inside has cavity 2, described cavity connects cooling water inlet pipe 3 and cooling water outlet pipe 4 respectively, described cooling water inlet pipe all is connected with cold water storage cistern 5 with described cooling water outlet pipe, be provided with spring base 6 in the middle of the described disk-shaped bottom bearing, described spring base is the annular with groove, one group of spring 7 is radially installed in described spring base the inside, and each described spring connects arc back-up block 8.
Embodiment 2:
Adopt the mode shown in Figure 1 annular neodymium iron boron magnetic body 9 of will waiting to polish to be installed on the arc back-up block on the spring during use, i.e. the another side of polishing is installed in available polishing and go up the plane polishing conversely after polishing finishes.
The disclosed technological means of the present invention program is not limited only to the disclosed technological means of above-mentioned technological means, also comprises by above technical characterictic any combination or is equal to the technical scheme that replacement is formed.Unaccomplished matter of the present invention belongs to those skilled in the art's common practise.
Claims (2)
1. water-cooled annular neodymium iron boron magnetic body plane polishing supporting adn fixing device, comprise the disk-shaped bottom bearing, it is characterized in that: described disk-shaped bottom bearing inside has cavity, described cavity connects cooling water inlet pipe and cooling water outlet pipe respectively, described cooling water inlet pipe all is connected with cold water storage cistern with described cooling water outlet pipe, be provided with spring base in the middle of the described disk-shaped bottom bearing, described spring base is the annular with groove, one group of spring is radially installed in described spring base the inside, and each described spring connects the arc back-up block.
