[0038] Working principle: Before using the large-angle multi-station tool for wire cutting, the overall condition of the device needs to be checked to determine whether it can work normally, and according to the size of the workpiece 4, the appropriate clamp base 201 is installed, and the workpiece 4 is placed on the installation table 1. Figure 1 Figure 8 ​As shown, during use, the fixture base 201 is fixed on the mounting table 1 by the moving component 3. The workpiece 4 is positioned and installed on the fixture base 201, with one side of it closely positioned against the L-shaped positioning strip 203. The conformal notch 211 on the conformal pressure plate 205 fits against the workpiece 4. The stud 212 passes through the clearance hole 206 and connects to the threaded hole 210, allowing the conformal pressure plate 205 to press the workpiece 4. After positioning and pressing, the part processing begins. After processing is completed, the stud 212 is loosened, allowing the conformal pressure plate 205 to release the workpiece 4 and remove the workpiece 4. Other stations follow the same operation to complete one processing cycle.

[0039] When installing the fixture base 201, the fixture base 201 is first inserted into the slide groove 214 through the moving block 213, and at the same time the extension plate 303 is placed between the two inserts 307. During this process, the pinch plate 304 is pinched to cause the spring 305 to contract, so that the pinch plates 304 come closer to each other and then separate, so that the insert post 306 can be smoothly inserted into the insert 307. Then, the rotating post 309 is rotated to make the compression pad 310 fit tightly against the bottom of the positioning groove 301, and the connecting block 302 can slide in and out of the positioning groove 301 to increase or decrease. Finally, the number of fixture bases 201 can be increased or decreased as needed, and the position of the fixture base 201 is not directly fixed by the screw hole, which increases the flexibility when its position changes.

[0040] By changing the clamping angle 202 of different clamping parts, the clamping base 201, in conjunction with the conformal pressure plate 205, can fix workpieces 4 of various shapes.

[0041] When the conformal pressure plate 205 presses down on the workpiece 4, the conformal pressure plate 205 will be affected by the workpiece 4 at this time.

[0042] The tilt angle corresponds to the tilt. After the stud 212 is inserted into the threaded hole 210, the nut will press against the top surface of the conformal pressure plate 205, so that the conformal pressure plate 205 is fixed. After the final fixation, the finger block 209 points to the scale of the angle mark 208, which is the tilt angle made by the conformal pressure plate 205 to adapt to the workpiece 4.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
