[0025] EMBODIMENT

[0026] REFERENCE Figures 1-4 A special fixing device for tungsten steel cutter coating, comprising a base 1, an extension plate 2 and a guide column 3, the bottom of the base 1 is fixedly connected with a rotating shaft, the bottom of the rotating shaft is embeddedly connected with a servo motor, when the cutter is coated, the servo motor can drive the base 1 to rotate through the rotating shaft, so that the cutter plate 8 at the upper end of the base 1 rotates, and then the cutter fixed in the cutter hole 9 keeps moving during processing, so as to ensure the uniformity of the coating of the cutter.

[0027] The bottom base 1 is fixedly connected with an extension plate 2 on one side, and the upper end of the extension plate 2 is fixedly connected with a guide column 3, and the outer side of the upper end of the guide column 3 is embeddedly connected with a connecting plate 6, the upper end of the connecting plate 6 is embeddedly connected with a knob 5, and the bottom of the knob 5 is embeddedly connected with an adjusting rod 4, one side of the connecting plate 6 is fixedly connected with a cover plate 7, the upper end of the bottom base 1 is embeddedly connected with a cutter plate 8, and a plurality of cutter insertion holes 9 are equally circumferentially arranged on the upper end of the cutter plate 8, and a limiting rod 10 is fixedly connected with the center of the upper end of the cutter plate 8, and the upper end and the bottom of the cover plate 7 of the bottom base 1 are both fixedly connected with a limiting insertion rod 11, and the bottom of the cutter plate 8 and the upper end of the limiting rod 10 are both provided with limiting holes 12, and the knob 5 is composed of a knob main body and an adjusting screw, and the adjusting screw is fixedly connected with the knob 5 through the connecting plate 6, through this design, when fixing the cutter, the staff can rotate the knob 5 to make the connecting plate 6 move in the screw rod, and then the cover plate 7 moves upward, when the connecting plate 6 moves in the screw rod, the connecting plate 6 can stably move up and down through the guiding effect of the guide column 3, so as to avoid the deflection of the connecting plate 6 and the cover plate 7, after the cover plate 7 moves upward, the limiting insertion rod 11 on the upper end of the cover plate 7 is separated from the limiting hole 12 on the upper end of the limiting rod 10, at this time, the staff can take out the cutter plate 8 and the limiting rod 10 from between the bottom base 1 and the cover plate 7, then the staff can insert the cutter into the cutter insertion hole 9 to complete the fixing work of the cutter, after the cutter is fixed, the staff can place the limiting rod 10 and the cutter plate 8 on the upper end of the bottom base 1, so that the limiting hole 12 on the bottom of the cutter plate 8 is clamped into the limiting insertion rod 11 on the upper end of the bottom base 1, after clamping, the staff can rotate the knob 5 to make the cover plate 7 move downward until the limiting insertion rod 11 on the bottom of the cover plate 7 is clamped into the limiting hole 12 on the upper end of the limiting rod 10, so as to fix the cutter plate 8 and the limiting rod 10 between the bottom base 1 and the cover plate 7.

[0028] It should be noted that the limiting insertion rod 11 is an equilateral hexagon as a whole, and the limiting hole 12 is an equilateral hexagonal insertion hole that is meshed with the limiting insertion rod 11 in size, so that after the limiting insertion rod 11 is inserted into the limiting hole 12, the bottom base 1 can drive the cutter plate 8 to rotate through the meshing of the limiting insertion rod 11 and the limiting hole 12 when rotating.

[0029] The inner wall of the milling cutter insertion hole 9 is embeddedly connected with a telescopic buckle 13, one side of the telescopic buckle 13 is embeddedly connected with a buckle base 14 inside the milling cutter insertion hole 9, and the lower end of the telescopic buckle 13 is fixedly connected with a damping ring 15 on the inner wall of the milling cutter insertion hole 9. Through this design, when fixing the milling cutter, the worker can directly insert the milling cutter into the milling cutter insertion hole 9. During this process, the upper end of the telescopic buckle 13 has a certain arc surface, which can push the telescopic buckle 13 away along the arc surface, so that the milling cutter is clamped inside the telescopic buckle 13. When the milling cutter is completely inserted into the inside of the milling cutter insertion hole 9, the damping ring 15 at the bottom of the milling cutter insertion hole 9 can further clamp the milling cutter inside the milling cutter insertion hole 9 by deforming itself and enhancing friction. Thus, the worker can directly fix the milling cutter in the milling cutter insertion hole 9 without rotating the milling cutter during the operation of fixing the milling cutter. When the milling cutter needs to be taken out, the worker only needs to pull it upwards.

[0030] The guide column 3 is a column body with an equilateral hexagonal shape, and the upper end of the guide column 3 is fixedly connected with a limiting plate. An equilateral hexagonal hole is provided in the inner side of the connecting plate 6, and the guide column 3 is embeddedly connected with the connecting plate 6 through the hole. Through this design, the connecting plate 6 can move up and down on the surface of the guide column 3 while avoiding horizontal deflection of the connecting plate 6 outside the guide column 3. In addition, the connecting plate 6 can avoid the situation that the limiting rod 11 at the bottom of the cover plate 7 cannot be smoothly inserted into the limiting hole 12 at the upper end of the limiting rod 10 during the downward movement of the cover plate 7.

[0031] The initial state of the telescopic buckle 13 is an extended state, and the telescopic buckle 13 has an arc shape that matches the curvature of the inner wall of the milling cutter insertion hole 9. The telescopic buckle 13 is connected with the buckle base 14 through a spring. Through this design, when the milling cutter is inserted into the milling cutter insertion hole 9, the milling cutter can push away the telescopic buckle 13, causing the telescopic buckle 13 to shrink towards the inner wall of the milling cutter insertion hole 9. Thus, after the milling cutter is inserted into the milling cutter insertion hole 9, the telescopic buckle 13 can clamp the milling cutter through the restoring force.

[0032] The damping ring 15 is a circular ring, and the damping ring 15 is fixedly connected to the lowermost end of the inner hole of the milling cutter insertion hole 9. Through this design, after the milling cutter is completely inserted into the inside of the milling cutter insertion hole 9, the damping ring 15 at the bottom of the milling cutter insertion hole 9 can wrap and clamp the milling cutter in all directions, further improving the stability of the milling cutter in the milling cutter insertion hole 9, and avoiding the situation that the milling cutter is separated from the milling cutter insertion hole 9 due to the centrifugal force during the rotation of the device.

[0033] Working principle: when the worker fixes the milling cutter, the worker can make the connecting plate 6 move in the screw rod mode by rotating the knob 5, so that the cover plate 7 moves upwards, and the connecting plate 6 can move stably up and down under the guidance of the guide column 3, so that the connecting plate 6 and the cover plate 7 are prevented from being deflected, the limiting rod 11 at the upper end of the cover plate 7 is separated from the limiting hole 12 at the upper end of the limiting rod 10, at this time the worker can take out the cutter plate 8 and the limiting rod 10 from between the base 1 and the cover plate 7, then the worker can insert the milling cutter into the milling cutter insertion hole 9 to complete the fixing work of the milling cutter, after the milling cutter is fixed, the worker can place the limiting rod 10 and the cutter plate 8 on the upper end of the base 1, so that the limiting hole 12 at the bottom of the cutter plate 8 is clamped into the limiting rod 11 at the upper end of the base 1, after clamping, the worker can make the cover plate 7 move downwards by rotating the knob 5 until the limiting rod 11 at the bottom of the cover plate 7 is clamped into the limiting hole 12 at the upper end of the limiting rod 10, so as to fix the cutter plate 8 and the limiting rod 10 between the base 1 and the cover plate 7, during the coating process, the servo motor continuously works, and the base 1 is driven to rotate by the rotating shaft, since the limiting rod 11 is an equilateral hexagon and is in toothed connection with the limiting hole 12 at the bottom of the cutter plate 8, when the base 1 rotates, the cutter plate 8 is driven to rotate synchronously, so that the milling cutter fixed in the milling cutter insertion hole 9 keeps moving during the machining process, and the uniformity of the milling cutter coating is ensured.

[0034] The above embodiment is a preferred embodiment of the present application, but the embodiment of the present application is not limited by the above embodiment, and any change, modification, replacement, combination and simplification made without departing from the spirit and principle of the present application should be an equivalent replacement mode, and all are included in the protection scope of the present application.

[0035] In the description of the present application, it should be understood that the terms indicating the position or location relationship are based on the position or location relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements indicated must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present application.
