[0002] The working principle of a Swiss-type lathe is that the cutting tool remains in a fixed position, and machining is completed through the movement and rotation of the spindle. This design is particularly suitable for machining high-precision, slender shaft parts. Swiss-type lathes can complete multiple composite machining processes in one operation, including turning, milling, drilling, boring, tapping, and engraving. Its highly efficient and multifunctional machining capabilities give it a significant advantage in the mass production of precision hardware and shaft parts.
[0003] However, during the machining process using a Swiss-type lathe, the fixture is prone to deformation or wear over a long period of use, which affects the stability of the fixture when clamping and fixing high-precision, slender shaft parts. This in turn affects the accuracy of the opening and the machining effect of high-precision, slender shaft parts during the production process, which can easily lead to defective products and waste.
[0004] Therefore, a clamping anti-slip fixture for holding the tail end of a Swiss Army machine bar is proposed to address the above problems. Summary of the Invention

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.
[0022] Example 1
[0023] As shown in Figures 1 to 5, a type of anti-slip clamping fixture for the tail end of a Swiss Army machine bar includes a worktable 1, a slide 8 above the worktable 1, a moving component on the upper surface of the worktable 1 and below the slide 8, a rotating seat 9 rotatably connected to the surface of the slide 8, and a servo motor for adjusting the rotation of the rotating seat 9 is bolted to the slide 8. A mounting base 10 is provided at one end of the rotating seat 9, and a placement groove 17 is provided on the surface of the mounting base 10. Three limiting grooves 11 are circularly distributed on the surface of the mounting base 10, and a limiting block 12 is slidably connected in each of the three limiting grooves 11. A clamping cavity 13 is fixedly connected to one end of the limiting block 12, and a miniature electric push rod 16 is provided in the clamping cavity 13. A clamping block 14 is connected to the output end of the miniature electric push rod 16, and a rubber sheet 15 is provided on the surface of the clamping block 14. The rubber sheet 15 has V-shaped serrated patterns on its surface. A drive component for moving the three clamping cavities 13 is provided in the mounting base 10.
[0024] In use, the device first places one end of the shaft part in the placement groove 17. Then, the drive assembly drives the three clamping cavities 13 to simultaneously approach the outer wall of the shaft part. At the same time, the clamping blocks 14 clamp and fix the shaft part. The rubber sheet 15 on the surface of the clamping blocks 14 increases the friction between the clamping blocks 14 and the shaft part, thereby improving the clamping and fixing of the shaft part. Meanwhile, the miniature electric push rod 16 in the clamping cavity 13 can further compensate for the clamping force between the clamping blocks 14 and the shaft part, improving the clamping and fixing effect of the shaft part.
[0025] Example 2
[0026] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, as shown in Figures 1 to 5. For details, please refer to the following description:
[0027] In a preferred embodiment, the drive assembly includes an adjusting screw 18 and a slant rod 19. The adjusting screw 18 is rotatably connected to the mounting base 10, and a sliding block is threadedly connected to the outer side of the adjusting screw 18. A slant rod 19 is hinged between the outer side of the sliding block and the bottom wall of each of the three limiting blocks 12. Furthermore, when the three clamping cavities 13 are moved and adjusted, the adjusting screw 18 can be rotated by a servo motor installed in the rotating base 9. Then, the sliding block threaded to the outer side of the adjusting screw 18 is driven to move downward by the rotating adjusting screw 18. Then, the sliding block adjusted by the downward movement cooperates with the slant rod 19 hinged between the sliding block and the bottom wall of the limiting block 12, thereby pulling the three clamping cavities 13, so that the three clamping cavities 13 drive the clamping blocks 14 to move closer to the shaft parts, and clamp and fix them by the clamping blocks 14.
[0028] In a preferred embodiment, the moving assembly includes a transverse moving slide 2, a threaded rod 3, and a moving block 4. Two transverse moving slides 2 are provided on the upper surface of the worktable 1. A threaded rod 3 is rotatably connected to one transverse moving slide 2, and a servo motor for adjusting the rotation of the threaded rod 3 is provided at one end of the threaded rod 3. The servo motor is installed on the outer wall of one end of the transverse moving slide 2. The moving block 4 is threadedly fitted onto the outer side of the threaded rod 3. A connecting rod is fixedly provided in the other transverse moving slide 2, and the moving block 4 is slidably fitted onto the outer side of the connecting rod. A moving plate 5 is fixedly connected above both moving blocks 4. Two longitudinal moving slides 6 are symmetrically provided on the upper surface of the moving plate 5. A drive screw is rotatably connected to one longitudinal moving slide 6, and a servo motor is provided at one end of the drive screw. The machine is configured to allow for rotational adjustment of the drive screw. The drive screw is located on the outer wall of one end of the longitudinal moving slide 6, and a slider 7 is threadedly fitted onto the outer side of the drive screw. A limit rod is fixedly installed in the other longitudinal moving slide 6, and a slider 7 is slidably fitted onto the outer side of the limit rod. The bottom wall of the slide block 8 is fixedly connected to the two sliders 7. Furthermore, during the adjustment of the device, the threaded rod 3 can be driven to rotate by a servo motor first. Then, the rotating threaded rod 3 drives the moving block 4 and the moving plate 5 mounted on the moving block 4 to move laterally. At the same time, the drive screw can be rotated by a servo motor, and the slider 7 and the slide block 8 mounted on the slider 7 can be driven to move longitudinally by the rotating drive screw, thereby moving and adjusting the rotating seat 9 and the mounting seat 10 to the appropriate position.
[0029] In a preferred embodiment, a protective cover 20 is provided on the upper surface of the worktable 1, and an observation window 21 for closing the protective cover 20 is hinged to the front surface of the protective cover 20. The protective cover 20 can protect the machining debris generated when machining shaft parts on the worktable 1, while the observation window 21 can be used to observe the machining of shaft parts inside the protective cover 20. The hinge angle between the inclined rod 19 and the limiting block 12 is 30°-60°, and the surface of the inclined rod 19 is provided with a wear-resistant coating. The heat dissipation groove is an array of ventilation holes with a diameter of 2-5mm, and a dust filter is embedded in the heat dissipation groove. The pitch of the drive screw is 4-8mm, and the surface of the limiting rod is provided with a polytetrafluoroethylene lubricating layer. The observation window 21 is a double-layer explosion-proof glass, and the inner surface is coated with an anti-fog coating.
[0030] The working process of this utility model is as follows: First, the adjusting threaded rod 3 can be rotated, and then the rotating threaded rod 3 drives the moving block 4 and the moving plate 5 set on the moving block 4 to move laterally. At the same time, the adjusting drive screw can be rotated, and the rotating drive screw drives the slider 7 and the slide seat 8 set on the slider 7 to move longitudinally. This allows the rotating seat 9 and the mounting seat 10 to move and adjust to a suitable position, so that the tool on the worktable 1 can process the shaft parts clamped and fixed on the mounting seat 10.
[0031] When it is necessary to clamp and fix shaft-like parts, one end of the shaft-like part can be placed in the placement groove 17 first. Then, the servo motor in the rotating seat 9 drives the adjusting screw 18 to rotate. Then, the rotating adjusting screw 18 drives the sliding block connected to the outer thread of the adjusting screw 18 to move down. Then, through the cooperation of the inclined rod 19 hinged between the sliding block adjusted by the lowering body and the bottom wall of the limiting block 12, the three clamping cavities 13 are pulled, so that the three clamping cavities 13 drive the clamping block 14 to move closer to the shaft-like part, and clamp and fix it. At the same time, the rubber sheet 15 on the surface of the clamping block 14 increases the friction between it and the shaft-like part, thereby improving the clamping and fixing of the shaft-like part. Then, the miniature electric push rod 16 in the clamping cavity 13 can further compensate the clamping force between the clamping block 14 and the shaft-like part, and improve the clamping and fixing effect of the shaft-like part. The above is the working principle of this anti-slip clamping fixture for the tail end of the Swiss-type machine bar stock.
