Description

Technical Field

[0001] This utility model belongs to the field of neodymium iron boron processing technology, and specifically relates to a fixture for V-shaped neodymium iron boron grinding. Background Technology

[0002] A profile grinding machine is a high-precision surface grinder capable of grinding, polishing, or coating the surface of materials. Its working principle is based on the simultaneous rotation of two parallel grinding wheels. Neodymium iron boron (NdFeB) materials are held in place by a conveyor belt and specific tooling. Through the relative movement of the grinding wheel grains and the material, the material is ground into the desired shape and precision.

[0003] For the processing of V-shaped NdFeB materials, the forming grinder cannot perform grinding directly. It is necessary to use some specific fixtures to assist in grinding. If the forming grinder is not used with specific fixtures, the processing speed is slow, the stability is poor, the dimensions are prone to defects, and the efficiency is low. Utility Model Content

[0004] In view of this, the purpose of this utility model is to address the shortcomings of the prior art by providing a fixture for V-shaped NdFeB grinding, thereby reducing the proportion of defective products and improving processing efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fixture for V-shaped NdFeB grinding includes a fixture body, a V-shaped groove on the top of the fixture body, limit blocks on both sides of the opening of the V-shaped groove, the limit blocks abutting against the workpiece being ground, and clearance grooves at the corners of the V-shaped groove.

[0007] To better realize this utility model, the above structure is further optimized, and the fixture body and the limiting block are integrated into one piece.

[0008] To better realize this utility model, the above structure is further optimized, and the clearance groove is an arc-shaped structure.

[0009] To better realize this utility model, the above structure is further optimized, and the diameter of the clearance groove at the bottom of the V-shaped groove is larger than the diameter of the clearance grooves on both sides.

[0010] To better realize this utility model, the above structure is further optimized, and the angle between the two inner walls of the V-shaped groove is 90°.

[0011] To better realize this utility model, the above structure is further optimized, and the angle between the two inner walls of the V-shaped groove and the bottom surface of the fixture body is 45°.

[0012] To better realize this utility model, the above structure is further optimized, and the main body of the clamp is a cuboid structure.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] The fixture for grinding V-shaped NdFeB iron boron iron workpieces provided by this utility model can be placed in it and ground with a grinding wheel. This solution provides uniform grinding force and high processing accuracy. The setting of limit blocks prevents the material from swaying left and right during grinding, which can cause product dimensional defects, reduce the defect rate, and ensure the stability of product quality. The use of clearance grooves can clear processing residues and facilitate the smooth progress of materials, so that the material does not get stuck during processing and avoids appearance defects such as indentations.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Please refer to Figures 1-3 The present invention provides a fixture for V-shaped NdFeB grinding, comprising a fixture body 1, which is a cuboid structure. A V-shaped groove 101 is formed at the top of the fixture body 1. In this embodiment, the bottom angle of the workpiece 3 being ground is a 90° right angle. Therefore, the angle between the two inner walls of the V-shaped groove 101 is 90°, allowing the workpiece 3 to be precisely placed within the V-shaped groove 101. The angle between the two inner walls of the V-shaped groove 101 and the bottom surface of the fixture body 1 is 45°, making the V-shaped groove 101 symmetrical. This allows for more precise positioning of the workpiece 3 placed within it, improving processing accuracy.

[0025] Furthermore, limit blocks 2 are provided on both sides of the opening of the V-shaped groove 101. The fixture body 1 and the limit blocks 2 are an integral structure, which is more robust and reliable. The limit blocks 2 abut against the workpiece 3 being ground, thereby preventing the material from swaying left and right during the grinding process and causing product dimensional defects, reducing the defect rate and ensuring the stability of product quality.

[0026] Each corner of the V-shaped groove 101 is provided with a clearance groove 4. The clearance groove 4 allows for the clearing of machining residues and facilitates the smooth flow of materials, preventing jamming during processing and avoiding defects such as indentations. The clearance groove 4 has an arc-shaped structure, which reduces stress concentration. The diameter of the clearance groove 4 at the bottom of the V-shaped groove 101 is larger than the diameter of the clearance grooves 4 on both sides. Since most of the chips generated during grinding accumulate at the bottom, increasing the volume of the bottom clearance groove 4 makes it easier to store and clean the chips.

[0027] During operation, the workpiece 3 is placed on the conveyor belt and enters the V-shaped groove 101 via the conveyor belt. After being ground by the coarse grinding wheel 5, the surface of the material is basically smooth, but the dimensions are still 0.05-0.08mm different from the finished product. After being ground by the fine grinding wheel 6, the dimensional accuracy is basically within the acceptable range. The reason for using a dual-station system instead of a single-station system is to avoid breakage caused by excessive grinding of the material, which would result in a long processing time.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
