[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3 This utility model provides an embodiment of an adjustable clamping fixture for tool production, comprising a positioning support 6, a rotating groove 12 on the inner side of the positioning support 6, a variable diameter support 14 rotatably connected to the inner side of the rotating groove 12, a rotating ring 17 on the right side of the variable diameter support 14, a guide plate 20 fixedly connected to the inner side of the variable diameter support 14, a plurality of second variable diameter grooves 21 on the inner side of the guide plate 20, a first variable diameter groove 15 on the right side of the positioning support 6, a first variable diameter rod 19 movably connected to the inner side of the first variable diameter groove 15, a variable diameter triangular block 18 fixedly connected to the left end of the first variable diameter rod 19, a second variable diameter rod 24 fixedly connected to the left end of the variable diameter triangular block 18, and the outer periphery of the second variable diameter rod 24 slidably connected to the inner side of the second variable diameter groove 21. A positioning groove 7 is opened on the right side of the positioning support 6, a guide support 1 is provided on the outer periphery of the right side of the positioning support 6, a plurality of sliding blocks 8 are provided on the outer periphery of the right side of the positioning support 6, a sliding groove 5 is provided on the inner side of the left end of the guide support 1, and the outer periphery of the sliding blocks 8 slides on the inner side of the sliding groove 5.

[0027] Liquid is injected into the inner cavity of the guide support 1 through the inlet 3, filling the cavity. The liquid in the guide support 1 pushes the sealing plate 9 to move to the left. Simultaneously, the positioning rod 13 slides in the positioning groove 7 set on the inner side of the right end of the positioning support 6, causing the positioning support 6 to rotate. At the same time, the displacement block 10 set on the inner side of the sealing plate 9 slides in the displacement groove 11. The movement of the positioning rod 13 pushes the rotating ring 17 set on the right end of the variable diameter support 14 to move to the left. The rotating ring 17 pushes the positioning support 6 to move to the left through the rotating groove 12 set inside the positioning support 6. Multiple sliding blocks 8 set on the right side of the positioning support 6 slide in the groove 8 set on the inner side of the left end of the guide support 1. The sliding of the inner side of the moving groove 5 causes the right end of the positioning support 6 to rotate inside the guide support 1, which in turn causes the first variable diameter rod 19 to slide inside the first variable diameter groove 15 set on the left side of the positioning support 6. This causes the second variable diameter rod 24 to slide inside the second variable diameter groove 21 set inside the guide plate 20, which in turn causes multiple variable diameter triangular blocks 18 to slide relative to each other, changing the displacement of the variable diameter triangular blocks 18 and fixing the workpiece. There is no need to change the fixture, and it can dynamically adapt to workpieces of different diameters. The relative sliding structure and symmetrical distribution of the variable diameter triangular blocks 18 form three uniform support points on the workpiece surface, ensuring that the geometric center of the workpiece is coaxial with the machine tool spindle when clamped, reducing machining errors caused by eccentricity.

[0028] Reference Figures 4-6 The positioning support 6 has a first circular hole 16 on its inner side, the guide plate 20 has a second circular hole 22 on its inner side, the guide support 1 has a guide deep hole 2 inside, the variable diameter support 14 has a third circular hole 23 on its right side, the rotating ring 17 has multiple positioning rods 13 fixedly connected to its right end, the positioning rods 13 are slidably connected to the inner side of the positioning groove 7, the positioning rods 13 are fixedly connected to the right side of the sealing plate 9, the sealing plate 9 has multiple displacement blocks 10 on its inner side, the guide support 1 has multiple displacement grooves 11 on its left inner side, the displacement blocks 10 are slidably connected to the inner side of the displacement grooves 11, the guide support 1 has an outlet 3 fixedly connected to its upper side, and the guide support 1 has an inlet 4 fixedly connected to its right end. The hydraulic pressure can be evenly distributed by the liquid acting on the sealing plate 9, avoiding workpiece deformation caused by overpressure of the fixture.

[0029] In tool production, when changing the clamping fixture, the right end of the guide support 1 is placed in the tool production lathe. The workpiece to be machined is placed inside the first round hole 16 and the guide deep hole 2 through the third round hole 23 and the second round hole 22. After machining, the liquid inlet is reduced and the liquid outlet 4 is increased to reduce the hydraulic pressure in the guide support 1, causing the sealing plate 9 to move to the right, which in turn moves other components to the right. This causes the variable diameter triangular block 18 to move outward relative to the second round hole 22, releasing the fixation on the workpiece and removing the workpiece.

[0030] Working principle: In tool production, when changing the clamping fixture, the right end of the guide support 1 is placed in the tool production lathe. The workpiece to be machined is placed inside the first round hole 16 and the guide deep hole 2 through the third round hole 23 and the second round hole 22. Liquid is injected into the inner cavity of the guide support 1 through the liquid inlet 3, filling the inner cavity of the guide support 1. The liquid in the inner cavity of the guide support 1 pushes the sealing plate 9 to move to the left. Simultaneously, the positioning rod 13 slides in the positioning groove 7 set inside the right end of the positioning support 6, causing the positioning support 6 to rotate. At the same time, the displacement block 10 set inside the sealing plate 9 slides inside the displacement groove 11. The movement of the positioning rod 13 pushes the rotating ring 17 set inside the right end of the variable diameter support 14 to move to the left. The rotating ring 17 passes through the rotating groove 12 set inside the positioning support 6. The positioning support 6 is pushed to the left, and the multiple sliding blocks 8 on the right side of the positioning support 6 slide inside the sliding groove 5 on the inner side of the left end of the guide support 1. This causes the right end of the positioning support 6 to rotate inside the guide support 1, which in turn causes the first variable diameter rod 19 to slide inside the first variable diameter groove 15 on the left side of the positioning support 6. This causes the second variable diameter rod 24 to slide inside the second variable diameter groove 21 on the inner side of the guide plate 20, which causes the multiple variable diameter triangular blocks 18 to slide relative to each other. This changes the displacement of the variable diameter triangular blocks 18 and fixes the workpiece. After processing, the liquid inlet is reduced and the liquid outlet 4 is increased to reduce the hydraulic pressure inside the guide support 1. This causes the sealing plate 9 to move to the right, which in turn causes other components to move to the right. This causes the variable diameter triangular blocks 18 to move outward relative to the second circular hole 22, releasing the fixation of the workpiece and allowing the workpiece to be removed.

[0031] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
