Abstract
The utility model provides a polishing, supporting and fixing device for an annular neodymium iron boron magnet plane. The polishing, supporting and fixing device solves the problem that an existing annular neodymium iron boron magnet plane polishing fixture is prone to inclination in the polishing process due to lack of effective supporting structures. The polishing, supporting and fixing device for the annular neodymium iron boron magnet plane comprises a disc-shaped bottom support, and is characterized in that a spring base is arranged in the middle of the disc-shaped bottom support, and the spring base is in an annular shape provided with a groove; a set of springs are arranged in the spring base in the radial direction, and each spring is connected with an arc-shaped supporting block; a set of balls are arranged on the disc-shaped bottom support. The polishing, supporting and fixing device for the annular neodymium iron boron magnet plane is applied to auxiliary supporting facilities in the polishing process of an 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 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 neodymium iron boron magnetic body is hard and crisp, the stability that clamps in the bruting process is effect and the yield rate of influence polishing directly.
Chinese patent CN201120256344.0 discloses a kind of neodymium iron boron thin-wall product fixture for processing, and specifically disclose following technical characterictic: these anchor clamps are the circle ring column structure that spring steel is made, one end of circle ring column is the anchor clamps fixing port, the other end is for clamping mouth, and at being axially arranged with and regulating seam of circle ring column, the telescopic chute that it is circular arc that the circle ring column lateral surface of regulating the opposite side of seam has a cross section.The utility model has solved the cracked problem of annulus thin-wall product, and the external diameter of annulus thin-wall product is not crushed, but owing to lacks the effective support structure, run-off the straight easily in the process of polishing.
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 plane polishing supporting adn fixing device, 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 plane polishing supporting adn fixing device, comprise the disk-shaped bottom bearing, 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, each described spring connects the arc back-up block, and one group of ball is installed on the described disk-shaped bottom bearing.
Described annular neodymium iron boron magnetic body plane polishing supporting adn fixing device, described spring is no less than 3.
Described annular neodymium iron boron magnetic body plane polishing supporting adn fixing device, the mode that described ball is inlayed by activity is installed on the described disk-shaped bottom bearing.
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, adopt the disk-shaped bottom bearing can play supporting role preferably, the disk-shaped bottom bearing is provided with ball simultaneously, the bottom surface scratch that the annular neodymium iron boron magnetic body rotates and causes in the process of avoiding polishing 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.
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.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, disk-shaped bottom bearing, 2, spring base, 3, spring, 4, the arc back-up block, 5, ball, 6, the annular neodymium iron boron magnetic body of waiting to polish.
The specific embodiment:
Embodiment 1:
As shown in Figure 1: annular neodymium iron boron magnetic body of the present utility model plane polishing supporting adn fixing device, comprise disk-shaped bottom bearing 1, be provided with spring base 2 in the middle of the described disk-shaped bottom bearing, described spring base is the annular with groove, one group of spring 3 is radially installed in described spring base the inside, each described spring connects arc back-up block 4, and one group of ball 5 is installed on the described disk-shaped bottom bearing.
Embodiment 2:
Embodiment 1 described annular neodymium iron boron magnetic body plane polishing supporting adn fixing device, described spring is no less than 3.
Embodiment 3:
Embodiment 1 or embodiment 2 described annular neodymium iron boron magnetic body planes polishing supporting adn fixing device, the mode that described ball is inlayed by activity is installed on the described disk-shaped bottom bearing.
Adopt the mode shown in Figure 1 annular neodymium iron boron magnetic body 6 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.
