[0026] like Figure 1 As shown, this embodiment provides a hole-machining fixture for CNC machining centers to process workpieces 3. This hole-machining fixture allows for the simultaneous clamping of multiple workpieces 3. The fixture includes a base 2 with multiple vertical ribs 23 on its top. A groove 21 is formed between adjacent vertical ribs 23 on the base 2. A workpiece 3 is placed within the groove 21, the width of which is adapted to the width of the workpiece 3. The height of the vertical ribs 23 is lower than the height of the workpiece 3. A linear motion mechanism is installed on the base 2 and the vertical ribs 23. A V-shaped pressure block 4 is installed on the output component of the linear motion mechanism, and the V-shaped surfaces 41 on both sides of the V-shaped pressure block 4 press down on the workpiece 3. In this embodiment, the workpiece 3 is placed in the groove 21, and the linear motion mechanism controls the V-shaped pressure block 4 to move downwards, clamping the workpiece 3. The CNC machining center then processes holes in the workpiece 3, enabling the simultaneous processing of multiple workpieces 3, reducing auxiliary time and improving processing efficiency.

[0027] Specifically, mounting through holes are provided on the base 2 and the upright rib 23. The linear movement mechanism includes a cylinder 1, which is installed at the bottom of the base 2. The output component of the cylinder 1 is located in the mounting through hole, and a V-shaped pressure block 4 is installed on the output component of the cylinder 1. In this embodiment, by activating the cylinder 1, the output component of the cylinder 1 drives the V-shaped pressure block 4 to move up and down, thereby releasing and pressing the workpiece 3.

[0028] More specifically, a positioning protrusion 22 is provided on the base 2 within the groove 21. The positioning protrusion 22 is located in the middle of the groove 21. Workpieces 3 can be placed into the groove 21 from both sides. The positioning protrusion 22 can simultaneously position two workpieces 3. Furthermore, each vertical rib 23 has mounting through holes on both sides of the positioning protrusion 22, and a V-shaped pressure block 4 is provided at each mounting through hole. Two workpieces 3 are placed in one groove 21, and two mounting through holes are provided on one vertical rib 23. Mounting through holes are also provided on the base 2 at corresponding positions of the mounting through holes on the vertical rib 23. A cylinder 1 is installed at each mounting through hole of the vertical rib 23, and a V-shaped pressure block 4 is installed on the output component of each cylinder 1. This allows two workpieces 3 to be placed in one groove 21, and the two cylinders 1 on each vertical rib 23 can clamp two workpieces 3, increasing the number of workpieces 3 that can be clamped at one time.

[0029] In this embodiment, the base 2, the upright rib 23, and the positioning protrusion 22 are integrally formed, which improves the clamping accuracy of the fixture and thus improves the accuracy of the machined hole.

[0030] The working process of the hole machining fixture in this embodiment is as follows:

[0031] Multiple cylinders 1 are started simultaneously, the output component of cylinder 1 extends outward, and the V-shaped pressure block 4 moves outward;

[0032] The workpiece 3 is placed in the groove 21, and the end of the workpiece 3 rests against the positioning protrusion 22;

[0033] Multiple cylinders 1 are started simultaneously. The output component of cylinder 1 retracts inward, the V-shaped pressure block 4 moves inward, the V-shaped surface 41 of the V-shaped pressure block 4 presses the workpiece 3, and the CNC machining center processes the workpiece 3.

[0034] This embodiment can clamp multiple workpieces 3 at once, resulting in high processing efficiency; the base 2 of the fixture is integrally formed, and the clamping accuracy of the fixture is high.

[0035] All instances of "described" have been removed as required, and other text has remained unchanged. The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto; the scope of protection of this utility model should be determined by the scope of the claims.
