Description

Technical Field

[0001] The utility model belongs to the technical field of numerical control milling cutter processing, in particular to a cutting device for a numerical control milling cutter. Background Technique

[0002] A numerical control milling cutter is a rotary cutter with one or more cutting teeth used for milling processing. During operation, each cutting tooth intermittently cuts off the surplus of the workpiece in turn. The milling cutter is mainly used in processing processes such as steps, grooves, formed surfaces, and cutting workpieces. When the numerical control milling cutter works for a long time, the cutting teeth will be damaged. In order to continue to use it, the damaged fracture surface will be cut and reused. However, the current cutting device is difficult to adjust the position of the numerical control milling cutter or the cutting teeth, resulting in the need for the staff to frequently disassemble and adjust the position of the numerical control milling cutter, which is likely to cause excessive cutting and waste of the numerical control milling cutter and the situation of secondary cutting due to insufficient cutting, thereby reducing the cutting efficiency of the numerical control milling cutter.

[0003] For example, the existing Chinese publication number is: CN217701650U, a cutting device for milling cutter processing, which: "includes a bottom table, and four corners at the bottom end of the bottom table are respectively fixed with support feet. A control box is fixed on the left side of the bottom table. A workbench is arranged on the top end of the bottom table. Clamping feet are respectively arranged on both sides at the front end of the top of the workbench. A fixed seat is vertically arranged at the rear end of the bottom of the workbench."

[0004] It can be seen that the cited patent document has the problem of being difficult to adjust the position of the milling cutter, resulting in excessive or insufficient cutting. Content of the Utility Model

Detailed implementation manners

[0024] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0025] Unless otherwise defined, the up, down, left, right, front, back, inner and outer directions involved in this article are all based on the up, down, left, right, front, back, inner and outer directions in the figures shown by the present utility model, and are hereby explained together.

[0026] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0027] Such as Figures 1 to 4 Shown is a cutting device of a numerical control milling cutter, including a workbench 1. Legs are installed on the bottom surface of the workbench 1 to raise the height of the workbench 1. A base 14 is fixedly provided on one side of the top surface of the workbench 1. A fixing plate 15 is fixedly provided on one side of the top surface of the base 14. A cylinder 16 is fixedly provided on the other side of the top surface of the base 14 through a rectangular plate. A clamping plate 17 is fixedly provided on the piston rod of the cylinder 16. Grooves for placing and clamping the numerical control milling cutter are respectively provided on the opposite side surfaces of the fixing plate 15 and the clamping plate 17. Place the numerical control milling cutter to be cut in the groove on one side surface of the fixing plate 15, and start the cylinder 16 to drive the clamping plate 17 to move, so that the groove on one side surface of the clamping plate 17 can abut against the numerical control milling cutter and clamp it, then the numerical control milling cutter can be clamped and fixed, which is convenient for subsequent cutting. The sizes of the two grooves are selected according to the actual situation to ensure that the numerical control milling cutter can be placed in the two grooves and clamped.

[0028] On one side of the top surface of the workbench 1, a U-shaped fixing frame 2 is fixedly installed. Slideways 3 are fixedly installed on the inner walls of both sides of the fixing frame 2. Chute grooves are provided on the opposite side surfaces of the two slideways 3. A bottom plate 4 is arranged between the two slideways 3. Sliders 5 that are slidably adapted to the chute grooves are fixedly installed on both side surfaces of the bottom plate 4, so that the bottom plate 4 can drive the two sliders 5 to move in the inner cavity of the chute groove, thereby enabling the bottom plate 4 to move between the two slideways 3.

[0029] Rotating shafts 6 are rotatably connected to the inner walls of both sides of the fixing frame 2 and below the two slideways 3. One end of the rotating shaft 6 penetrates through one side surface of the fixing frame 2 and is fixedly provided with a turning handle 11. Driving gears 7 are symmetrically fixedly installed on the circumferential side of the rotating shaft 6. Rack bars 8 that are meshed with the driving gears 7 are symmetrically fixedly installed on the bottom surface of the bottom plate 4. By the staff rotating the turning handle 11, the turning handle 11 drives the rotating shaft 6 to rotate below the two slideways 3, so that the rotating shaft 6 can drive the two driving gears 7 to rotate. The two rotating driving gears 7 will drive the bottom plate 4 to move through the two meshed rack bars 8, enabling the staff to drive the bottom plate 4 to perform a reciprocating lateral movement by rotating the turning handle 11 forward and backward.

[0030] An electric push rod 9 is fixedly installed on the top surface of the bottom plate 4 through a bracket. The output end of the electric push rod 9 penetrates through the bracket and is provided with cutting teeth 10 for cutting a numerical control milling cutter through a vertical rod. A motor is arranged on one side surface of the vertical rod. The output shaft of the motor penetrates through the vertical rod and is fixedly connected to the central position of the cutting teeth 10. When the bottom plate 4 moves, it will drive the electric push rod 9 and the cutting teeth 10 to move through the bracket, enabling the cutting teeth 10 to move above the numerical control milling cutter. According to different fracture surfaces of the numerical control milling cutter, the cutting teeth 10 can move directly above the fracture surface. Then, the electric push rod 9 is turned on, so that the electric push rod 9 drives the vertical rod and the cutting teeth 10 to move downward. At the same time, the motor is turned on, so that the motor drives the cutting teeth 10 to rotate, enabling the cutting teeth 10 to cut the numerical control milling cutter, reducing the situation of excessive or insufficient cutting when cutting the numerical control milling cutter, thereby improving the cutting efficiency of the numerical control milling cutter.

[0031] Screw holes 13 are opened on one side surface of the turning handle 11 and one side surface of the fixing frame 2. There is one screw hole 13 on one side surface of the turning handle 11. A number of screw holes 13 on one side surface of the fixing frame 2 are equidistantly arranged and are arranged in a circular array. Bolts 12 are threadedly connected to the inner cavities of the two screw holes 13 that are aligned in position on one side surface of the turning handle 11 and one side surface of the fixing frame 2. After rotating the turning handle 11 to drive the bottom plate 4 to move to a suitable position, the screw hole 13 on one side surface of the turning handle 11 will be aligned with one of the screw holes 13 on one side surface of the fixing frame 2. At this time, the bolt 12 is inserted into the two aligned screw holes 13, so as to fix the position of the turning handle 11, thereby fixing the position of the bottom plate 4, avoiding the situation that the turning handle 11 rotates during work due to accidental touch by the staff or external collision, so that the cutting teeth 10 move during the cutting process.

[0032] Working principle:

[0033] For the cutting device of the CNC milling cutter, place the CNC milling cutter to be cut in the groove of the fixing plate 15, and turn on the air cylinder 16 to drive the clamping plate 17 to move, so that the groove on one side of the clamping plate 17 can squeeze the CNC milling cutter, thereby fixing the position of the CNC milling cutter. At this time, turn the handle 11, and let the handle 11 drive the two transmission gears 7 to move through the rotating shaft 6, so that the two transmission gears 7 drive the bottom plate 4 to move through the two meshing racks 8. The bottom plate 4 drives the two sliders 5 to move in the inner cavity of the slideway 3, so that the bottom plate 4 can drive the cutting teeth 10 to move through the bracket, and according to the fracture surface of the CNC milling cutter, the cutting teeth 10 can move to directly above the fracture, and then turn on the electric push rod 9 to drive the cutting teeth 10 to move downward. At the same time, turn on the motor to drive the cutting teeth 10 to rotate, so that the cutting teeth 10 can cut the fracture surface of the CNC milling cutter, reducing the situation of excessive or insufficient cutting when cutting the CNC milling cutter, thereby improving the cutting efficiency of the CNC milling cutter.
