Abstract
Description
Technical Field
[0001] This utility model relates to the field of parts processing, specifically to an auxiliary fixture for sandblasting. Background Technology
[0002] In the traditional sandblasting and shaping process for M-shaped parts, several problems often arise that affect product quality and appearance consistency:
[0003] Firstly, traditional sandblasting shaping fixtures often result in uneven sandblasting intensity at both ends of the product during surface sandblasting, leading to smaller dimensions at both ends after processing and noticeable color differences, affecting the overall aesthetics and consistency of the product. Therefore, a sufficient support structure is necessary.
[0004] Secondly, in traditional processes, the high-speed steel balls used in sandblasting exert significant impact on the cantilever structure at the top of the product, easily causing deformation. This deformation not only affects the dimensional accuracy of the product but can also lead to functional failure, especially for precision parts. Therefore, even with a supporting structure, rigid connections can still cause damage to parts due to impact.
[0005] Furthermore, when traditional fixtures secure products, the clamping points can obstruct the sandblasting medium, preventing these areas from being effectively sandblasted and creating "masked areas." These un-sandblasted areas exhibit significant surface finish differences compared to the sandblasted areas, affecting not only appearance but also potentially leading to uneven coating adhesion and other subsequent processing problems. Therefore, the obstruction issues inherent in traditional fixing methods during processing must be considered.
[0006] These issues collectively lead to the challenges of low efficiency and inconsistent quality in traditional sandblasting processes when handling complex parts, necessitating corresponding improvements.
[0007] To address the aforementioned issues, we have made a series of improvements. Utility Model Content
[0008] The purpose of this invention is to provide an auxiliary fixture for sandblasting, so as to overcome the above-mentioned shortcomings and deficiencies of the prior art.
[0009] An auxiliary fixture for sandblasting includes: a base support, an elastic fixing bracket, a first fixing member, and a second fixing member. The base support is symmetrically arranged on both sides of the elastic fixing bracket. The ratio of the bottom diameter to the top diameter of the elastic fixing bracket is 11:9. The first fixing member and the second fixing member are cylindrical structures. The first fixing member is located in the middle of the elastic fixing bracket, and the second fixing member is located at the top of the elastic fixing bracket.
[0010] Furthermore, the first and second fixing members are symmetrically arranged on the front and rear sides of the elastic fixing bracket, and the middle sections of the first and second fixing members are connected to the elastic fixing bracket.
[0011] The beneficial effects of this utility model are:
[0012] Compared with traditional technologies, this invention avoids the problem of product deformation during sandblasting; at the same time, it does not affect the sandblasting effect of the product. Attached image description:

[0017] The present invention will be further described below with reference to specific embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.
[0018] Example 1
[0019] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2 This is a structural schematic diagram from another perspective of the present invention.
[0020] like Figure 1-2 As shown, an auxiliary fixture for sandblasting includes: a base support 100, an elastic fixing bracket 200, a first fixing member 300, and a second fixing member 400. The base support 100 is symmetrically arranged on both sides of the elastic fixing bracket 200. The ratio of the bottom diameter to the top diameter of the elastic fixing bracket 200 is 11:9. The first fixing member 300 and the second fixing member 400 are cylindrical structures. The first fixing member 300 is located in the middle of the elastic fixing bracket 200, and the second fixing member 400 is located at the top of the elastic fixing bracket 200.
[0021] The first fixing member 300 and the second fixing member 400 are symmetrically arranged on the front and rear sides of the elastic fixing bracket 200, and the middle sections of the first fixing member 300 and the second fixing member 400 are connected to the elastic fixing bracket 200.
[0022] This invention is applicable to M-shaped parts or parts with two sides and a middle part. The method of use is to insert the first fixing member 300 and the second fixing member 400 into the middle of the side of the M-shaped part and the middle part, then push the structure upwards to lock the first fixing member 300 and the second fixing member 400 into the M-shaped part, thus completing the installation. Then, fix this invention to the area to be sandblasted.
[0023] Design principle: First, the sandblasting process requires sufficient support. This utility model adopts a structural design that combines a base bracket 100 and an elastic fixed bracket 200. The base bracket 100 is symmetrically arranged on both sides of the elastic fixed bracket 200, providing a stable foundation support and ensuring that the parts will not shift or shake during the impact of high-speed steel balls.
[0024] Its force application method is different from the traditional two-sided clamping. Instead, it uses the tension generated by the outward expansion of the elastic fixing bracket 200 to achieve fixation. This utility model adopts a special ratio of 11:9 elastic fixing bracket 200, which is wider at the bottom and narrower at the top. During the upward pushing process, the first fixing part 300 and the second fixing part 400 on both sides will lock with the M-shaped part, ensuring both firmness and stability, and effectively ensuring the uniformity and accuracy of sandblasting.
[0025] Secondly, traditional rigid connections can damage parts due to impact. In this invention, the elastic fixing bracket 200 has a design that is wider at the bottom and narrower at the top. Therefore, the angle of the base bracket 100 connected to it also follows the elastic fixing bracket 200. Thus, when subjected to sandblasting impact, both the base bracket 100 and the elastic fixing bracket 200 possess a certain degree of elasticity, rather than a rigid connection with a vertical structure. This absorbs some of the impact energy during sandblasting, reducing the impact force of the steel balls on the parts, especially the cantilever structure, and effectively preventing deformation of the top of the parts. Simultaneously, the cylindrical design of the first fixing member 300 and the second fixing member 400 can evenly distribute pressure, further protecting the structural integrity of the parts.
[0026] Finally, regarding the issue of the obscured area, this invention designs a first fixing member 300 and a second fixing member 400, which are symmetrically arranged on the front and rear sides of the elastic fixing bracket 200. The cylindrical first fixing member 300 and the second fixing member 400 are then connected to the inner side of the part. As long as the fixing method of clamping from the outside is used, there will always be an obscured problem. Therefore, this invention adopts an expansion fixing method from the inside out, so that the surface of the M-shaped part has no contact with any other structure, ensuring the consistency and integrity of the surface treatment of the part, and effectively solving the color difference problem caused by traditional clamps.
[0027] Compared with traditional technologies, this invention avoids the problem of product deformation during sandblasting; at the same time, it does not affect the sandblasting effect of the product.
[0028] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
