Abstract
The utility model provides a water-cooling type supporting fixing device for polishing of the plane of an annular neodymium-iron-boron magnet. Due to the fact that the Curie temperature of the neodymium-iron-boron magnet is low and is about 312 DEG C, temperature stability is poor, polishing under a high temperature is limited, if a workpiece is high in temperature in the polishing process, magnetic property of the neodymium-iron-boron magnet can be faded, and the effect of the using function is influenced. The water-cooling type supporting fixing device comprises a disc type bottom support, a cavity is formed in the disc type bottom support, and the cavity is respectively connected with a cooling water inlet pipe and a cooling water outlet pipe. The cooling water inlet pipe and the cooling water outlet pipe are connected with a cold water tank, and a spring seat is arranged in the middle of the disc type bottom support. The spring seat is annular and provided with a groove, a set of springs are arranged in the spring seat in the radial direction, and each spring is connected with an arc supporting block. The water-cooling type supporting fixing device is an auxiliary supporting facility 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 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 purpose of this utility model is that the problem at above-mentioned existence provides a kind of water-cooled annular neodymium iron boron magnetic body plane polishing supporting adn fixing device, in bruting process, can avoid the too fast rising of neodymium iron boron magnetic body temperature, guarantee 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 utility model 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 utility model 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 utility model 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 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.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
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 utility model 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:
Embodiment 1 described water-cooled annular neodymium iron boron magnetic body plane polishing supporting adn fixing device, described spring is no less than 3.
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 utility model scheme 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 utility model belongs to those skilled in the art's common practise.
