[0028] As shown Figures 1 to 7 in the figure, a positioning device for milling cutter processing includes: a machine shell 1, a cutting head moving assembly 2, and a clamping assembly 5;

[0029] A jaw moving assembly 3 is also installed beside the cutting head moving assembly 2. The jaw moving assembly 3 consists of a second motor 31, a second screw 32, and a first jaw 33. The output shaft of the second motor 31 is fixedly connected to the second screw 32, and the second screw 32 is threadedly connected to the first jaw 33. By starting the second motor 31 to drive the second screw 32 to rotate, the first jaw 33 moves on the second screw 32, facilitating the adjustment of the horizontal position of the second jaw 43, the adjustment of the distance between the milling cutter and the tool head, and the grinding process of the milling cutter.

[0030] The cutting head moving assembly 2 consists of a first motor 21, a first screw 22 rotatably installed at the output shaft of the first motor 21, and a cutting assembly 23 for processing the milling cutter. The cutting assembly 23 includes a moving plate 231, a sliding groove 233 opened on the moving plate 231, and a cutting head 232 sliding in the sliding groove 233. The moving plate 231 is threadedly connected to the first screw 22. One end of the cutting head 232 is rotatably installed on the moving plate 231, and the other end is slidably installed in the sliding groove 233. When the first motor 21 is started, it drives the first screw 22 to rotate, driving the moving plate 231 to move left and right to adjust the position of the cutting head 232. As Figure 5 shown in the figure, in the initial state, the cutting head 232 is horizontally aligned with the second screw 32. One end of the cutting head 232 rotates around the end not in the sliding groove 233 in the sliding groove 233, and the tool head of the cutting head 232 touches the tool head position of the milling cutter. The thinner the milling cutter, the longer the sliding distance of the cutting head 232 in the sliding groove 233 when it needs to contact the milling cutter. The thicker the milling cutter, the shorter the sliding distance of the cutting head 232 in the sliding groove 233 when it needs to contact the milling cutter, so as to process and polish milling cutters of different thicknesses;

[0031] As a supplement: The cutting head 232 can be placed at the tool groove of the milling cutter manually, so that the cutting head 232 rotates following the position of the tool groove of the milling cutter. A motor can also be installed at the position where it is rotatably installed on the moving plate 231, and it can be adjusted according to the actual working conditions.

[0032] The clamping assembly 5 is composed of a clamping block 51, a rotating disk 52, a rotating wheel 53, and a worm 54; the clamping block 51 is slidably connected to the rotating disk 52, the rotating disk 52 is fixedly connected to the rotating wheel 53, the rotating wheel 53 is rotatably connected to the worm 54, a quarter gear is provided on the side wall of the rotating wheel 53, and the worm 54 meshes with the quarter gear on the side wall of the rotating wheel 53. The cutting head 232 is located at the center of the circle of the three clamping blocks 51. A motor is installed at the center of the rotating wheel 53. Three card slots corresponding to the clamping blocks 51 are opened on the rotating disk 52, and the clamping blocks 51 slide in the card slots. By rotating the worm 54, the rotating wheel 53 is driven to rotate, causing the rotating disk 52 to rotate accordingly. At the same time, through the rotation of the three card slots on the rotating disk 52, the three clamping blocks 51 move towards the center, clamping the handle of the milling cutter, making the center of the milling cutter located at the center of the three clamping blocks 51, so that when grinding the cutting head of the milling cutter, the center of the milling cutter can be accurately ground;

[0033] As a supplement: By manually rotating the worm 54 or installing a threaded screw on the worm 54, it can be selected according to the actual working conditions. At the same time, the position of the cutting head 232 is horizontally equal to the center position of the three clamping blocks 51. And when the milling cutter rotates, the height of the cutting head 232 will also change with the height of the grooved position of the cutting head of the milling cutter, so that the cutting head 232 can position and grind the cutting head at any time.

[0034] A transmission assembly 4 is also installed in the machine shell 1. The transmission assembly 4 includes a transmission motor 41, a transmission 42, and a second jaw 43; the output shaft of the transmission motor 41 is rotatably connected to the transmission 42, and the transmission 42 is rotatably connected to the second jaw 43. By driving the second jaw 43 to clamp the milling cutter through the rotation of the transmission motor 41, it can cooperate with the first jaw 33 to cut off and divide the center of the long milling cutter.

[0035] Working principle:

[0036] By starting the second motor 31 to drive the second screw 32 to rotate, the first jaw 33 moves on the second screw 32, which is convenient for adjusting the horizontal position of the second jaw 43, facilitating the adjustment of the distance between the milling cutter and the cutting head, facilitating the grinding process of the milling cutter. Adjust the position of the cutting head 232. One end of the milling cutter can rotate. At this time, the thinner the milling cutter, the greater the deviation angle of the cutting head 232 from the horizontal position; the thicker the milling cutter, the smaller the deviation angle of the cutting head 232 from the horizontal position, so that the cutting edge position of the cutting head 232 is always inside the cutter groove of the milling cutter to grind the milling cutter. And the position of the cutting head 232 in the inner cutter groove of the milling cutter is also adaptively adjusted according to the different depths of the cutter groove opened. By rotating the three card slots, the three clamping blocks 51 move towards the center to clamp the handle of the milling cutter, making the center of the milling cutter located at the center of the three clamping blocks 51, so that when grinding the cutting head of the milling cutter, the center of the milling cutter can be accurately ground.
