Embodiment 1
[0048] Such as figure 1 , figure 2 , image 3 with Figure 4 as shown,
[0049] The power head is a device that drives the tool 33 to rotate to generate the main cutting motion. It is composed of a power unit 31, a collet 32 and a tool 33; the output shaft of the power unit 31 is coaxially connected with the collet 32, and the power unit 31 drives the collet 32 rotation, collet 32 is used for clamping cutter 33, and the axis of rotation of cutter 33 is collinear with the axis of collet 32 after clamping, and cutter can be drill bit or milling cutter; The preferred electric energy of the energy source of power unit 31, power unit 31 comprises The motor 311 is driven by the motor 311 to rotate the collet 32. The output shaft of the motor 311 can be directly connected coaxially with the collet 32, or it can also include a main shaft reducer 312. After the torque of the motor 311 is amplified by the main shaft reducer 312, The output shaft of the main shaft reducer 312 is...
Embodiment 2
[0056] Such as Figure 5 As shown, on the basis of Embodiment 1, in order to increase the torque that drives the variable-diameter guide rail 41 to rotate so that the cutter 33 can obtain greater cutting force, the first speed reducer 52 and the first hand wheel 521 are added; the first speed reducer 52 The housing is fixedly connected with the fixed seat 13, and the output shaft of the first speed reducer 52 and the rotating shaft 51 ( Figure 4 shown) coaxial fixed connection, it can also be understood that the output shaft of the first reducer 52 is the rotating shaft 51, the input shaft of the first reducer 52 is coaxially fixedly connected with the first handwheel 521, and the peripheral surface of the first handwheel 521 is set There is a scale, and the corresponding position of the first reducer 52 is provided with an indicator mark, and the scale value when the first handwheel 521 is rotated is read to obtain the rotation angle of the variable diameter guide rail 41. T...
Embodiment 3
[0059] Such as Image 6 As shown, on the basis of the second embodiment, the Z-axis handwheel 241 is changed to a Z-axis CNC motor 242, and the output shaft of the Z-axis CNC motor 242 is coaxially connected with the Z-axis screw rod, and the Z-axis CNC motor 242 The housing is fixedly connected with the Z-axis guide rail 24; the second handwheel 411 is changed to the second numerically controlled motor 412, and the output shaft of the second numerically controlled motor 412 is coaxially connected with the variable diameter screw rod; the shell of the second numerically controlled motor 412 The body is fixedly connected with the variable-diameter guide rail 41. In order to reduce the radius of rotation of the variable-diameter guide rail 41 for a compact structure, the second numerical control motor 412 is preferably fixedly connected with the first end of the variable-diameter guide rail 41; the first hand wheel 521 is changed to the first The numerically controlled motor 522...
