[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1 Please see Figure 1-6 This is the first embodiment of the present invention. This embodiment provides a special clamping device for anti-rotation interface of machinable base column, which can stably clamp the anti-rotation interface of machinable base of different specifications, and can also automatically install and disassemble the machinable base.

[0023] Specifically, it includes: a clamping component 1, a driving component 2 fixedly disposed at the top of the clamping component 1, a pressing component 3 movably connected to the driving component 2, a pushing component 4 in contact with one end of the pressing component 3, and a housing 5 slidably connected to the pushing component 4; the bottom of the pressing component 3 is in movable contact with the top of the clamping component 1, and the top of the pressing component 3 is fixedly connected to the inner wall of the housing 5.

[0024] Furthermore, the clamping assembly 1 includes an annular rail 11, an annular shaft 12 fixedly disposed at the bottom of the annular rail 11, six sets of connecting frames 13 movably connected to the outer wall of the annular shaft 12, and six sets of umbrella-shaped clamps 14 movably connected to one end of each connecting frame 13; wherein, the included angle between each set of connecting frames 13 is 90 degrees, the included angle between each set of umbrella-shaped clamps 14 is also 90 degrees, and serrations 15 are symmetrically distributed on both sides of the tip of each umbrella-shaped clamp 14.

[0025] In practical use, the six sets of umbrella-shaped clamps 14 are first aligned with the anti-rotation interface, and then the annular shaft 12 is pressed down. Because the bottom of the umbrella-shaped clamps 14 is in contact with the bottom of the anti-rotation interface, the annular shaft 12 can drive the six sets of connecting brackets 13 to move towards the six included corners of the anti-rotation interface. When the six sets of umbrella-shaped clamps 14 are in contact with the six included corners, the anti-rotation interface of the machinable base is securely clamped. The anti-rotation interface of the machinable base is usually hexagonal, with six included corners formed between the six sides. Therefore, the design of the six umbrella-shaped clamps 14 allows them to extend deep into the included corners of the anti-rotation interface. The serrations 15 on the umbrella-shaped clamps 14 are in contact with the six sides of the anti-rotation interface, providing strong friction during rotation. This design ensures that the machinable base will not loosen or slip during rotation, improving the reliability of clamping.

[0026] Furthermore, the extrusion assembly 3 includes an annular groove 31, an extrusion disc 32 fixedly disposed on the top of the annular groove 31, a mounting base 33 fixedly disposed on the extrusion disc 32, and a roller 34 rotatably connected to the mounting base 33. The extrusion disc 32 has a through hole 35 at its center, and two sets of limiting holes 36 are symmetrically arranged on both sides of the through hole 35.

[0027] Furthermore, the annular rail 11 and the annular groove 31 cooperate with each other, and the extrusion disc 32 is rotatably connected to the annular rail 11 through the annular groove 31.

[0028] Furthermore, the extrusion assembly 3 also includes two sets of limiting posts 37 respectively inserted into the two sets of limiting holes 36, a mounting plate 38 fixedly disposed on the end of the limiting post 37 away from the limiting hole 36, and two sets of springs 39 fixedly disposed on the mounting plate 38. The other end of the spring 39 is fixedly connected to the extrusion plate 32, and the limiting post 37 is located inside the spring 39.

[0029] Furthermore, the pushing component 4 includes a wedge frame 41, two sets of sliders 42 fixedly disposed at both ends of the wedge frame 41, an opening 43 opened at the inclined end of the wedge frame 41, and a bending frame 44 fixedly disposed at the other end of the wedge frame 41. The inclined surface of the wedge-shaped frame 41 is in contact with the roller 34.

[0030] In actual use, the wedge frame 41 is first pushed toward the center of the extrusion plate 32. The roller 34 continuously contacts the wedge frame 41. Under the extrusion force provided by the slope of the wedge frame 41, the mounting base 33 drives the extrusion plate 32 to move toward the direction of the annular shaft 12. The annular shaft 12 is also squeezed and driven to move toward the center of the anti-rotation interface. At this time, the six sets of umbrella-shaped clamps 14 will be in close contact with the six corners of the anti-rotation interface to achieve stable clamping.

[0031] Preferably, the wedge frame 41 is designed so that simply pushing the wedge frame 41 can achieve a stable clamping of anti-rotation interfaces of different specifications. This is because as the wedge frame 41 moves towards the center point of the extrusion disc 32, the closer the wedge frame 41 is to the center point of the extrusion disc 32, the larger the area of ​​the six sets of umbrella-shaped clamps 14, and the larger the anti-rotation interface it can accommodate. Simultaneously, the spring 39 is gradually stretched during this process. When the wedge frame 41 is released, the elastic force of the spring 39 automatically resets the clamping assembly 1 and the pushing assembly 4, facilitating the next use. The function of the limiting post 37 passing through the limiting hole 36 is to allow the extrusion disc 32 to stably push the annular shaft 12 towards the center of the anti-rotation interface.

[0032] Even better, the roller 34 contacts the inclined surface of the wedge frame 41, which can smoothly transmit the compressive force. The rolling contact of the roller 34 is more efficient than direct sliding contact and can significantly reduce the friction between the wedge frames. This design not only extends the service life but also improves the stability and reliability of the equipment.

[0033] Furthermore, the drive assembly 2 includes a motor 21, a worm gear 22 connected to the output end of the motor 21, a worm wheel 23 cooperating with the worm gear 22, a rotating shaft 24 fixedly disposed at the bottom of the worm wheel 23, and an elastic shaft 25 fixedly disposed at the end of the rotating shaft 24 away from the worm wheel 23; wherein, the end of the elastic shaft 25 away from the rotating shaft 24 passes through the through hole 35 and is fixedly connected to the annular shaft 12, the width of the opening 43 is greater than the diameter of the rotating shaft 24, and the rotating shaft 24 is rotatably connected to the mounting plate 38.

[0034] In practical use, after clamping the anti-rotation interface, start the motor 21. The motor 21 drives the worm 22 to rotate, the worm 22 drives the worm wheel 23 to rotate, the worm wheel 23 drives the rotating shaft 24 to rotate, the rotating shaft 24 drives the elastic shaft 25 to rotate, the elastic shaft 25 drives the annular shaft 12 to rotate, and the annular shaft 12 drives the six sets of umbrella-shaped clamps 14 to rotate, thus enabling the installation and removal of the machinable base.

[0035] It should be noted that the elastic shaft 25 has its own telescopic function. When the extrusion disc 32 moves toward the annular shaft 12, the elastic shaft 25 will also be affected by the extrusion disc 32 and move toward the center of the anti-rotation interface along with the annular shaft 12 (the elastic shaft 25 is existing technology and will not be described in detail here).

[0036] Secondly, the design of the annular rail 11 and the annular groove 31 working together reduces the friction between the extrusion disc 32 and the rotating annular shaft 12. Since the extrusion disc 32 does not rotate, the annular rail 11 rotates along the annular groove 31 when the annular shaft 12 rotates. The width of the opening 43 is greater than the diameter of the rotating shaft 24 because, during clamping of the anti-rotation interface, the wedge-shaped frame 41 gradually moves towards the center of the extrusion disc 32. Since the center of the through hole 35 is the center of the extrusion disc 32, and the rotating shaft 24 passes through the through hole 35, the opening 43 provides rotational space for the rotating shaft 24, preventing contact between the wedge-shaped frame 41 and the rotating shaft 24.

[0037] Furthermore, a notch 51 is provided on one side of the housing 5 to facilitate the movement of the bending frame 44, and symmetrical grooves 52 are provided inside the housing 5 to facilitate the movement of the two sets of sliders 42. Two sets of locking blocks 53 are also symmetrically arranged on the inner wall of the housing 5. The extrusion plate 32 is located inside the two sets of locking blocks 53, and the side wall of the locking block 53 slides in contact with the side wall of the extrusion plate 32.

[0038] Preferably, the design of the locking block 53 is such that, since the roller 34 and the mounting base 33 are located at one end of the extrusion plate 32, when the wedge frame 41 extrudes the roller 34, the extrusion plate 32 will tip over. Through the structural design of the locking block 53 sliding contacting the side wall of the extrusion plate 32, the extrusion plate 32 can move in the vertical direction. The locking block 53 plays a limiting role in this process, effectively preventing the extrusion plate 32 from tipping over due to uneven force.

[0039] Furthermore, the mounting plate 38 is located inside the housing 5, and the housing 5 is fixedly connected to the mounting plate 38; a control switch 54 is fixedly installed on the side of the housing 5 opposite to the notch 51. A sensor is installed inside the control switch, which is used to control the forward and reverse rotation of the motor. (The connection between the control switch and the motor is prior art and will not be described in detail here.) In actual use, the operator first holds the housing 5, then aligns the six sets of umbrella-shaped clamps 14 with the center of the anti-rotation interface and brings them into contact with the anti-rotation interface. Next, the operator uses their thumb to push the bending frame 44 along the notch 51 towards the anti-rotation interface. The two sets of sliders 42 move along the groove 52, causing the wedge-shaped frame 41 to move smoothly inside the housing 5 towards the center of the extrusion plate 32, thus achieving a stable clamping of the anti-rotation interface. Then, the operator presses the control switch 54 with their other finger. The control switch 54 transmits an electrical signal to the drive motor 21. Upon receiving the signal, the drive motor 21 drives the worm gear 22 to rotate, enabling the installation and removal of the machinable base.

[0040] It should also be noted that by pushing the bending frame 44 with the thumb and pressing the control switch 54 with the other finger, the operator can complete the entire clamping and driving operation with one hand. This design makes the operation more flexible, eliminating the need for the operator to use both hands simultaneously, thus improving the convenience and flexibility of the operation.

[0041] It should also be noted that by pushing the bending frame 44 with the thumb and pressing the control switch 54 with the other finger, the operator can complete the entire clamping and driving operation with one hand. This design makes the operation more flexible, eliminating the need for the operator to use both hands simultaneously, thus improving the convenience and flexibility of the operation.

[0042] In summary, this specialized clamping device for anti-rotation interfaces of machinable base columns achieves stable clamping of machinable bases of different specifications through its clamping component design. Utilizing six sets of umbrella-shaped clamps in close contact with the anti-rotation interface, combined with the strong friction provided by the saw teeth, it ensures stable clamping of machinable bases of varying sizes. Simultaneously, the synergistic action of the extrusion and pushing components ensures a smooth and adjustable clamping process, adapting to anti-rotation interfaces of different sizes. This significantly improves the reliability and stability of clamping, effectively preventing loosening or slippage of the machinable base during machining, and guaranteeing machining accuracy and quality.

[0043] Next, the bending frame is clamped by pushing with the thumb, while the control switch is pressed with the other finger to control the rotation of the drive assembly, thus completing the installation and removal of the machinable base. This clearly defined operating method not only improves the flexibility and convenience of operation but also reduces the number of steps and the possibility of misoperation, enabling workers to perform processing tasks more efficiently, reducing labor intensity, and improving work efficiency.

[0044] Finally, through mechanisms including the fit between the annular rail and the annular groove, the rolling contact between the rollers and the wedge frame, and the automatic return function of the springs, friction and wear between components are effectively reduced, extending the service life of the equipment. Simultaneously, the smooth transmission of clamping force and precise position adjustment ensure the stability and reliability of the equipment during long-term use, reducing maintenance costs and improving its economy and practicality.
