Description

Technical Field

[0001] This utility model belongs to the field of grinding and processing technology, and specifically relates to a grinding and processing fixture for ferrite material products. Background Technology

[0002] During the metal powder injection molding process, the sintered products can undergo various deformations. Many factors affect the product dimensions, including raw material density, sintering temperature, atmosphere, sintering cycle, raw material ratio process, shrinkage stress of the product structure itself, ceramic plate support, etc. If one or more of these factors are unreasonable, it will lead to dimensional defects in the product. Moreover, the types and degrees of defects in the same batch of sintered products are different.

[0003] Ferrite material products, manufactured using powder metallurgy, are in high demand. During production, high dimensional accuracy is required, which traditional forming methods cannot meet. Grinding, a machining process, can be used to ensure product precision. To guarantee the accuracy of grinding, a high-efficiency and precision-guaranteed tooling fixture needs to be designed.

[0022] Figure 8 The processed product. Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0024] Conversely, this utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model as defined in the claims. Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art will fully understand this utility model even without these detailed descriptions.

[0025] Please see Figure 1-8 A grinding fixture for ferrite material products includes a base plate 1, a fixing block 2, a positioning cover plate 3, a positioning insert 4, and a magnet 5. The fixing block 2 is fixed on the base plate 1, the positioning cover plate 3 is fixed on the fixing block 2, the positioning insert 4 is disposed between the positioning cover plate 3 and the fixing block 2, and the ferrite material product 6 is positioned on the positioning insert 4 and attracted by the magnet 5.

[0026] Specifically, the base plate 1 has three placement slots 101, with the center of the base plate 1 as the reference point, and each positioning slot is set at a 60° angle.

[0027] Specifically, each placement slot 101 is provided with a fixing block 2, which is fastened by screws.

[0028] Specifically, the positioning cover plate 3 is stacked on the fixing block 2 and is fixedly installed on the fixing block 2 by a set of screws.

[0029] Specifically, each positioning cover plate 3 has four insert mounting slots 301, and each insert mounting slot 301 has a mounting platform slot 302 on one side of its inner groove.

[0030] Specifically, the positioning insert 4 is placed in the insert mounting groove 301. A raised platform 401 is provided on one side of the insert. The platform 401 is inserted into the corresponding platform groove 302. The contact between the platform groove 302 and the platform 401 limits the positioning insert 4. The upper part of the positioning insert 4 has a structure that matches the bottom of the ferrite material product 6, facilitating product placement (providing initial positioning during placement; after grinding, based on shape matching, a tight fit is formed after extrusion, facilitating the removal of the product and the fixture). A circular hole is provided in the middle of the positioning insert 4, and a magnet 5 is tightly fitted inside the hole. The diameter of the circular hole is 0.05mm smaller than the diameter of the magnet 5, used to attract the product and further improve the product's positioning stability.

[0031] The working process of this utility model fixture is as follows:

[0032] Ferrite material product 6 is placed into the corresponding positioning insert 4 in a fixed direction. The magnetic attraction is used to limit the ferrite material product 6. 12 products are placed at a time. Then the entire fixture with the products is placed on the grinding equipment for grinding. After the grinding process is completed, the grinding fixture is removed, the ground products are taken out one by one, and the grinding fixture is cleaned.

[0033] After grinding, the central structure of the ferrite material product 6 is removed, exposing the magnet 5, which adsorbs the waste generated during processing (at this time, due to the continuous squeezing force of the grinding disc, the product is already tightly attached to the positioning insert 4 and is moved away with the clamping fixture). This avoids the waste from affecting the size of the ground product and improves the efficiency of the grinding disc's self-cleaning. After every 10 grinding cycles, the waste on the magnet 5 needs to be manually cleaned (by blowing or brushing).

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
