[0002] When processing metal workpieces, the workpieces are often clamped and fixed with fixtures before using tools for processing. For some large workpieces, it is difficult to clamp them with traditional fixtures because the fixtures are generally larger than the workpieces. For very large workpieces, the cost of making larger fixtures is high. In addition, for large workpieces, the manufacture and installation of conventional fixtures are relatively complicated and require special design and customization, which increases manufacturing costs and processing cycles.
[0003] Traditional methods of fixing large workpieces include using heavy-duty fixtures or custom fixtures, but these methods have some disadvantages. Heavy-duty fixtures are not only expensive, but also inflexible and difficult to adapt to workpieces of different shapes and sizes. Custom fixtures can meet the specific needs of workpieces, but they have a long manufacturing cycle, high cost, and are not universal.
[0004] Therefore, it is necessary to provide a new large workpiece fixing structure that can flexibly adapt to workpieces of different sizes and shapes and at the same time has stable fixing performance and convenient operation. Utility Model Content

[0029] The embodiment of the present application provides a fixing structure for a large workpiece, comprising:
[0030] A placement table, comprising a placement surface, wherein the placement surface has a first direction and a second direction perpendicular to the first direction, and the placement table is provided with a plurality of fixing holes at equal intervals along the first direction and the second direction;
[0031] A fixture block, the workpiece is located on the placement table and the workpiece has a clamping portion, the fixture block is fixedly connected to the placement table, and the clamping portion is clamped between the fixture block and the placement table, and a sliding groove is opened on the fixture block, and the sliding groove is connected to one of the fixing holes;

[0033] The large workpiece fixing structure provided above designs fixing holes on the placement table where the workpiece is placed, and selects fixing holes at different positions to set fixture blocks to fix the workpiece according to the size of the workpiece. At the same time, the fixing parts can slide in the sliding groove, and the distance between the fixing holes and the workpiece can be supplemented during installation. In this way, the large workpiece fixture can be flexibly adapted to workpieces of different sizes and shapes and at the same time have stable fixing performance and easy operation.
[0034] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0035] See also Figure 1-Figure 3 , an embodiment of the present application provides a fixing structure 100 for a large workpiece, comprising a placement table 1, a fixture block 2 and a fixing member 3, the placement table 1 having a placement surface 11, the placement surface 11 having a first direction a and a second direction b perpendicular to the first direction a, the placement table 1 having a plurality of fixing holes 12 equally spaced along the first direction a and the second direction b, the workpiece is located on the placement table 1 and has a clamping portion 4, the fixture block 2 is fixedly connected to the placement table 1, and the clamping portion 4 is clamped between the fixture block 2 and the placement table 1, a sliding groove 21 is provided on the fixture block 2, the sliding groove 21 is connected to one of the fixing holes 12, a fixing member 3, the fixing member 3 passes through the sliding groove 21 and the fixing hole 12, and the fixing member 3 is fixedly connected to the placement table 1.
[0036] Specifically, the placement table 1 has a placement surface 11, and the placement surface 11 has a first direction a and a second direction b perpendicular thereto, and a plurality of fixing holes 12 are provided at equal intervals along the two directions. The placement table 1 provides a flat support surface to ensure that the workpiece is placed firmly on it. The reason why the first direction a and the second direction b are perpendicular is to act as a plane coordinate system, so that the fixing holes 12 are arranged equidistantly along the first direction a and the second direction b respectively so that each fixing hole 12 acts as a positioning point on the coordinate system, and the fixing holes 12 at different positions are selected according to the size of the workpiece to set the fixture block 2. The equidistant setting of the fixing holes 12 provides a variety of fixing position options, which is suitable for workpieces of different sizes and shapes. The fixture block 2 is fixedly connected to the placement table 1, has a sliding groove 21, and is clamped with the clamping portion 4 of the workpiece. The function of the fixture block 2 is to fix the workpiece on the placement table 1 and provide additional support. The existence of the sliding groove 21 allows the fixing member 3 to be connected to the fixing hole 12 through it, so that the clamp block 2 can be adjusted and moved relative to the placement table 1 to adapt to workpieces of different sizes and shapes. The fixing member 3 passes through the sliding groove 21 and the fixing hole 12 and is fixedly connected to the placement table 1. The function of the fixing member 3 is to ensure that the clamp block 2 and the workpiece are firmly fixed on the placement table 1 to prevent them from moving or swinging during the processing. Through the setting of the fixing member 3, the position of the workpiece can be easily adjusted and fixed to adapt to different processing requirements. At the same time, the fixing member 3 is also slidably connected to the sliding groove 21, so that there is no need to completely remove the fixing member 3 from the placement table 1. Just loosen it a little to make the clamp block 2 slide relative to the fixing member 3, thereby further adjusting the position of the clamp block 2 on the placement table 1 to adapt to some workpieces of special sizes.
[0037] In a specific example, in one case, the outside of the workpiece has a clamping portion 4 , the fixture block 2 is located outside the workpiece, and the clamping portion 4 is clamped between the fixture block 2 and the placement table 1 .
[0038] Specifically, the workpiece outer side has a clamping portion 4 means that the design of the workpiece has some protruding or convex parts, which are used as the basis for clamping or clamping the workpiece. These clamping portions 4 can be a part of the design, or can be an additional fixture or clamping device. The clamping portion 4 is arranged on the outer side of the workpiece in one case.
[0039] Further, placing the fixture block 2 and the clamping portion 4 on the outside of the workpiece can provide more convenient access because the operator can directly access them without having to fix them inside the workpiece itself. This simplifies the fixing and adjustment process, saving time and labor costs. Placing the fixture block 2 and the clamping portion 4 on the outside of the workpiece can reduce the risk of collision with processing equipment or other tools. If the fixture block 2 and the clamping portion 4 are located inside the workpiece, they may collide with the tool or other equipment during processing, causing damage or accidents. Placing the fixture block 2 and the clamping portion 4 on the outside of the workpiece can make it suitable for smaller workpieces that are not convenient to install fixtures inside. Since the outside of the workpiece is usually flat or has a regular geometric shape, it is easier to design and install the fixture block 2 and the clamping portion 4.
[0040] In a specific example, in one case, the workpiece has a clamping portion 4 on the inner side, the fixture block 2 is located on the inner side of the workpiece, and the clamping portion 4 is clamped between the fixture block 2 and the placement table 1 .
[0041] Specifically, this means that the design of the workpiece has some internal concave or convex parts, which are used as the basis for clamping or clamping the workpiece. These clamping parts 4 can be a part of the workpiece itself, or they can be specially designed fixtures or clamping devices, and the clamping parts 4 are arranged on the inner side of the workpiece in one case.
[0042] Furthermore, placing the fixture block 2 and the clamping portion 4 on the inside of the workpiece can reduce interference and damage to the workpiece surface. Setting the fixture block 2 on the outside requires that the outer surface of the workpiece is prone to scratches or wear, while the internal fixture can avoid this situation, thereby protecting the integrity and quality of the workpiece surface. Placing the fixture block 2 and the clamping portion 4 inside the workpiece can hide them, making the workpiece look neater and more beautiful. This is especially important for products that require fine processing on the surface of the workpiece or need to be displayed, because external fixtures may have an adverse effect on the appearance of the workpiece, and some workpieces may have complex shapes or structures. External fixtures may be difficult to fix, while internal fixtures can more easily adapt to these special shapes. Therefore, placing the fixture block 2 and the clamping portion 4 on the inside of the workpiece can improve the applicability and flexibility of workpieces with special shapes.
[0043] In a specific example, the end of the fixing member 3 away from the clamp block 2 has a threaded portion 31, and a hexagonal nut 5 is threadedly connected to the threaded portion 31. The maximum outer diameter a of the hexagonal nut 5 and the diameter b of the fixing hole 12 are related by the formula: a>b.
[0044] Specifically, one end of the fixing member 3 has a threaded portion 31, so that the fixing member 3 can be fixed on the placement table 1 by rotation. The threaded portion 31 is usually designed as a standard thread so as to be used in conjunction with the hexagonal nut 5. A hexagonal nut 5 is connected to the threaded portion 31 for tightening the fixing member 3. The design of the hexagonal nut 5 allows it to be fixed or loosened by a twisting operation, thereby adjusting the position of the workpiece or replacing the workpiece. The maximum outer diameter a of the hexagonal nut 5 is greater than the diameter b of the fixing hole 12. This relationship ensures that the hexagonal nut 5 has enough space around the fixing hole 12 so that it can completely cover the outside of the fixing hole 12. The purpose of this is to ensure that the connection between the fixing member 3 and the placement table 1 can provide sufficient stability and firmness to prevent the workpiece from moving or shaking during processing.
[0045] In a specific example, a rotating portion 32 is provided on one end of the fixing member 3 away from the placing table 1 , and the fixing member 3 is rotated by fixing the hexagonal nut 5 and rotating the rotating portion 32 .
[0046] Specifically, one end of the fixing member 3 is designed with a special component, which is called a rotating portion 32. This component can be a convex, concave or a special shape structure, which is used for a specific connection tool or handle to achieve a rotating operation.
[0047] Further, the hexagonal nut 5 is temporarily fixed by an external tool, serving as a threaded hole corresponding to the threaded portion 31 , and then the fixing member 3 is screwed into the hexagonal nut 5 by an external tool to fix the clamp block 2 .
[0048] In a specific example, the placement platform 1 has a placement area 13 on one side away from the fixture block 2 , and a plurality of weight-reducing holes 14 are respectively opened in the placement area 13 along the first direction a and the second direction b.
[0049] Specifically, the placement area 13 on the placement table 1 is a specific area, which is usually located at the edge of the placement table 1 or on the side away from the fixture block 2. This area is specially designed to place additional parts or equipment to facilitate processing operations or other required scenarios. A plurality of weight-reducing holes 14 are opened in the placement area 13 along the first direction a and the second direction b. These weight-reducing holes 14 are usually circular or other specific shaped holes, which reduce the weight of the workpiece by reducing the amount of material on the workpiece. These holes can be arranged in an equidistant manner or according to specific design requirements. Furthermore, the weight-reducing holes 14 are opened along the first direction a and the second direction b to reduce the difficulty of opening. Opening along the first direction a or the second direction b facilitates the processing machine to perform repeated opening and reduces the complexity of the processing procedure.
[0050] In a specific example, a reinforcing rib 15 is provided in the placement area 13 , and two ends of the reinforcing rib 15 are fixedly connected to two opposite surfaces in the placement area 13 .
[0051] Specifically, the placement area 13 is provided with reinforcing ribs 15, which are a structural support element for enhancing the stability and strength of the placement area 13. The reinforcing ribs 15 are usually located inside the placement area 13, along the edge or in the lateral direction of the placement area 13, to provide uniform support and structural support, and the placement area 13 is surrounded by the side of the placement table 1. The reinforcing ribs 15 in the placement area 13 are usually located between these side surfaces to provide additional structural support and stability. Therefore, "directly opposite" refers to two opposite faces in the placement area 13, which are located on the diagonal line of the placement area 13 and are symmetrical to each other.
[0052] "Fixed connection" means that the two ends of the reinforcing rib 15 or other structural component are connected to the two opposite surfaces in the placement area 13 in a fixed manner to ensure that they will not move or swing during use. This fixed connection can be in various forms, such as welding, bolt connection, screw connection, adhesive connection, etc., depending on the material, structural design and application requirements.
[0053] In a specific example, the fixture block 2 is coated with anti-rust paint.
[0054] Specifically, the clamp block 2 is usually made of metal, such as steel or aluminum alloy. The metal surface is easily affected by moisture and oxygen in the air and oxidized, thereby causing rust. By applying anti-rust paint, a protective covering layer can be formed to block the contact of air and moisture, effectively prevent oxidation and corrosion on the surface of the clamp block 2, and extend its service life. By applying anti-rust paint on the clamp block 2, the maintenance requirements of the clamp block 2 can be reduced. Anti-rust paint can reduce the oxidation rate of the surface of the clamp block 2, reducing the need for regular cleaning and maintenance, thereby reducing maintenance costs and workload.
[0055] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
