Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically a fixed position spacer. Background Technology

[0002] Vacuum aging is a metal heat treatment process that involves heating and holding the material in a vacuum environment to alter its internal structure, thereby increasing its strength and hardness. Its core principle is to induce the precipitation of strengthening phases within the material through the combined effects of temperature and time. For example, in beryllium copper, it promotes the precipitation of beryllium compounds from the copper matrix, thus enhancing hardness and elasticity.

[0003] During the production process, when loading round bars for vacuum aging, they are laid flat on the mesh. When there are few products, there is a risk of rolling. When there are many products, they will stick together, which is not conducive to the flow of air. Utility Model Content

[0004] The purpose of this invention is to provide a fixed-position spacer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed-position spacer, comprising a mesh fixture, a spacer component, and a combined component. The spacer component is movably inserted into the surface of the mesh fixture, and the combined component is vertically inserted into the four opposite corners of the mesh fixture. The spacer component comprises a spacer body, a fixed stake, a first connecting stake, and a second connecting stake. The bottom of the spacer body is vertically provided with a fixed stake, and the sides of the spacer body are symmetrically and horizontally provided with first connecting stakes, and the sides of the spacer body are also symmetrically and horizontally provided with second connecting stakes.

[0006] Furthermore, the mesh fixture includes a mesh body, combination holes, and anchoring holes. Combination holes are provided at the four opposite corners of the mesh body, and anchoring holes are provided on the surface of the mesh body.

[0007] Furthermore, the main body of the mesh adopts a thickened structure, and the anchoring holes are arranged in an equidistant array on the surface of the main body of the mesh.

[0008] Furthermore, the fixed stakes are arranged in a circular array with the spacer body as the center, and there are four sets of them. The fixed stakes and the spacer body are integrated into one structure.

[0009] Furthermore, the first connecting pile and the second connecting pile are arranged in a cross shape on the side surface of the main body of the sleeve, and the second connecting pile and the first connecting pile have an insert structure combination.

[0010] Furthermore, all four sets of fixed stakes are tightly fitted to the inner side of the anchoring hole, and the second connecting stake, the first connecting stake and the spacer body are welded together.

[0011] Furthermore, the combined component includes a combined rod, a connector, a tenon, and a mating hole. The connector is installed at the end of the combined rod near the mesh tooling, and a tenon is provided at one end of the combined rod. A mating hole is provided at the end of the combined rod away from the tenon.

[0012] Furthermore, the tenon and the hole are connected by a thread, and the lower end of the connector has a hole structure with the same structure as the hole. Moreover, the lower end of the connector and the combined hole are connected to each other by an insertion structure.

[0013] This utility model provides a fixed-position spacer, which has the following beneficial effects:

[0014] 1. This utility model, by providing a spacer component and anchoring holes on the surface of the mesh body, allows for the vertical insertion of the product into the spacer body. The fixed stakes at the bottom of the spacer body are then inserted into the anchoring holes. This enables rapid assembly and connection of the mesh fixture and spacer component, providing excellent structural support for the product. The aforementioned structure creates effective structural anchor points, allowing for control of the product's loading position within a certain adjustment range and effectively preventing arbitrary movement of the round bar product. This ensures sufficient structural stability during processing and avoids contact between structural components that could affect processing results. Furthermore, the internal through-structure of the spacer component, combined with the hollow structure of the mesh fixture, ensures good airflow between the products, guaranteeing optimal processing results.

[0015] 2. This utility model, by providing a first connecting pile and a second connecting pile on the side of the spacer body, utilizes the structural insertion between the first and second connecting piles to allow the spacer components to be inserted into the surface of the mesh fixture while simultaneously splicing and combining adjacent spacer bodies. This provides good structural support between spacer components while multiple spacer components are spliced ​​onto the surface of the mesh fixture, thereby avoiding unnecessary structural shaking and offset, and further preventing contact between products. In addition, by providing a combination component, by inserting the connecting piece into the combination hole and screwing one end of the combination rod into the upper end of the combination rod, the mesh fixtures can be structurally stacked and combined, thereby ensuring the expandability of the device structure. The use of the tenon and the connection hole at both ends of the combination rod allows the spacing between the stacked mesh fixtures to be adjusted to match the product specifications, thereby further ensuring the flexibility of the structural components and providing good structural support.

The second connecting pins 204 are also symmetrically arranged horizontally on the sides of the spacer body 201. The fixed pins 202 are distributed in a circular array structure with the spacer body 201 as the center, and four sets are arranged. The fixed pins 202 and the spacer... The main body 201 is set as an integral structure. The first connecting pile 203 and the second connecting pile 204 are distributed in a "+" shape on the side surface of the spacer body 201. The second connecting pile 204 and the first connecting pile 203 have an insertable structure combination. The four sets of fixed inserts 202 are tightly attached to the inner side of the anchoring hole 103. The second connecting pile 204, the first connecting pile 203 and the spacer body 201 are welded together. The product is vertically inserted into the interior of the spacer body 201 and the fixed inserts 202 at the bottom of the spacer body 201 are inserted into the anchoring hole 103. This allows for the quick combination and connection of the mesh tooling 1 and the spacer component 2, while providing good structural support for the product.

[0023] like Figures 1 to 4 As shown, the mesh fixture 1 includes a mesh body 101, combination holes 102, and anchoring holes 103.

The lower end of the connector 302 is connected to the combination hole 102 by an insertion structure. By using the structure between the first connecting post 203 and the second connecting post 204, the spacer component 2 can be inserted into the surface of the mesh fixture 1 while the adjacent spacer body 201 is spliced ​​together. In addition, by providing the combination component 3, the connector 302 is inserted into the interior of the combination hole 102 and one end of the combination rod 301 is screwed into the upper end of the combination rod 301. By using this structure, the mesh fixture 1 can be structurally superimposed and combined.

[0024] In summary, as Figures 1 to 4 As shown, when using this fixed position spacer, firstly, according to the product specifications and quantity, prepare an appropriate number of mesh fixtures 1, spacer components 2, and combination components 3. Then, according to the product specifications, screw multiple combination rods 301 together using the tenon 303 and the hole 304 at both ends to connect them end to end and combine them into an appropriate length. Then, screw the bottom end of the combined rod 301 into the top of a set of connectors 302, and screw the top of the combined rod 301 into the bottom end of another set of connectors 302. At the same time, insert the bottom end of the connector 302 into the combination hole 102 at the opposite corner of the mesh body 101. With this structure, multiple mesh fixtures 1 can be stacked and combined vertically with the cooperation of the combination components 3.

[0025] Then, multiple sets of spacer components 2 are inserted into the anchoring holes 103 using the fixing pins 202 at the bottom of the spacer body 201. At the same time, adjacent spacer components 2 are inserted using the structure of the first connecting pin 203 and the second connecting pin 204 to achieve splicing and combination between them. Finally, the product to be processed is vertically inserted into the spacer body 201.
