[0033] The technical solution of the present utility model will be further described below with reference to the drawings and through specific embodiments.

[0034] When processing semiconductor components, it is necessary to use a tool to mill multiple surfaces of the workpiece to be processed to obtain semiconductor components. In the prior art, the workpiece to be processed needs to be clamped multiple times to achieve milling processing of different surfaces. Moreover, due to the lack of a suitable fixture, the clamping difficulty is relatively high, and multiple clampings will result in a relatively high precision error of the product, leading to a relatively high rejection rate and causing unnecessary losses.

[0035] To solve the above problems, as Figures 1 to 3As shown in the figure, this embodiment provides a fixture. This fixture includes a clamping portion 1, a supporting portion 2 and a locking member. The clamping portion 1 is clamped by a vise 300. The supporting portion 2 protrudes from the clamping portion 1. The supporting portion 2 includes a supporting surface 21. The workpiece 100 to be machined is placed on the supporting surface 21. The locking member is configured to lock the workpiece 100 to the supporting portion 2. The workpiece 100 is locked to the fixture by the locking member, and then the fixture is clamped by the vise 300. The clamping difficulty is low. Five-sided milling of the workpiece 100 can be achieved with one clamping, without multiple clamps, reducing the number of clamping times, and effectively avoiding the situation of high precision error of the product 200 caused by multiple clamps, reducing unnecessary losses in production operations.

[0036] As Figure 4 shown, this is the product 200 obtained after milling the workpiece 100 to be machined. It can be seen from the figure that the product 200 has a groove. It can be understood that the wall surface of the workpiece 100 facing the supporting surface 21 is also provided with a groove.

[0037] Preferably, as Figure 1 shown, positioning blocks 3 protrude from the supporting surface 21. When the workpiece 100 to be machined is placed on the supporting surface 21, the positioning blocks 3 can be clamped in the grooves. Through the cooperation of the positioning blocks 3 and the grooves, the workpiece 100 can be positioned quickly and accurately, ensuring that the workpiece 100 can be easily placed in the correct position of the fixture, reducing the time for clamping and adjusting the workpiece 100, and improving production efficiency. After the positioning blocks 3 are inserted into the grooves, the shaking of the workpiece 100 caused by vibration or external force during the machining process can be reduced, thereby ensuring the stability and reliability of the machining process.

[0038] Furthermore, the number of grooves on the workpiece 100 is multiple, and the number of positioning blocks 3 is also multiple. Each positioning block 3 can be clamped in a corresponding groove. Through the one-to-one cooperation of multiple positioning blocks 3 and multiple grooves, the positioning of the workpiece 100 can be faster and more accurate, ensuring that the workpiece 100 can be machined according to the preset coordinates and directions.

[0039] Specifically, the locking member sequentially passes through the clamping portion 1, the supporting portion 2, and a part of the workpiece 100 to be machined, so that the workpiece 100 to be machined is locked to the supporting portion 2. The locking member can directly pass through the clamping portion 1 and the supporting portion 2, and then partially penetrate into the workpiece 100 to be machined, realizing a tight connection between the workpiece 100 to be machined and the supporting portion 2, ensuring that the workpiece 100 to be machined can maintain a stable position during the machining process and is not prone to movement or shaking, thereby improving the machining accuracy and stability. By simply rotating or pushing and pulling the locking member, the clamping and releasing of the workpiece 100 to be machined can be realized, simplifying the operation process and improving the work efficiency. It can be understood that the clamping portion 1, the supporting portion 2, and the workpiece 100 to be machined are all provided with assembly holes 4 for the locking member to pass through. It should be noted that the specific number of the locking members is determined according to actual needs, and this embodiment does not limit this.

[0040] In this embodiment, the locking member is a screw. The disassembly and assembly of the screw are simple, the material is easy to obtain, the cost is low, and it has excellent firmness and is not easy to loosen or fall off. It can be understood that at this time, the assembly holes 4 provided in the clamping portion 1, the supporting portion 2, and the workpiece 100 to be machined are threaded holes.

[0041] In other embodiments, the locking member can also be a rivet, a bolt, etc., and this embodiment does not limit this.

[0042] Preferably, please refer to Figure 1 、 Figure 3 , the shape and size of the supporting surface 21 are the same as the outer contour of the product 200. Through this setting, it can be ensured that during the milling process, the tool will not interfere with the fixture, and there is no need to re-clamp and position for machining, and only one clamping is required.

[0043] In this embodiment, as Figure 1 shown, at least part of the two side walls of the clamping portion 1 along the first direction protrude from the corresponding two side walls of the supporting portion 2 along the first direction, and the vise 300 clamps the clamping portion 1 along the first direction. Exemplarily, as Figure 1 shown, the first direction is the width direction of the fixture. By making the width of the clamping portion 1 greater than the width of the supporting portion 2, the positioning of the fixture in the vise 300 is more accurate, and the operator can quickly identify the clamping portion 1 of the fixture and quickly place the fixture in the vise 300 so that the vise 300 clamps the clamping portion 1.

[0044] Preferably, an anti-slip layer is provided on the wall surface of the clamping portion 1 that abuts against the vise 300. The protective layer can increase the friction coefficient between the clamping portion 1 and the vise 300, making the clamping more stable and preventing the fixture from slipping or shifting due to vibration or other external forces during the machining process.

[0045] In some embodiments, the anti-slip layer is a rubber layer. In other embodiments, an anti-slip coating is convexly provided on the wall surface where the clamping portion 1 abuts against the vise 300 to form the anti-slip layer. Among them, the main components of the anti-slip coating are granular anti-slip particles and a special adhesive.

[0046] Specifically, the clamping portion 1 and the supporting portion 2 are integrally formed. The integral forming manufacturing process simplifies the production process of the fixture and reduces the errors caused by the assembly of multiple components. Since there is no additional assembly link, the precise matching between the clamping portion 1 and the supporting portion 2 can be ensured, improving the overall accuracy and reliability of the fixture.

[0047] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
