DETAILED DESCRIPTION

[0019] Example 1

[0020] like Figures 1 to 4 As shown, this embodiment provides a linked groove milling device, including a grinding wheel bed 50 and a workpiece bed 60, and also includes: a groove milling mechanism and a head frame mechanism.

[0021] The groove milling mechanism is installed on the grinding wheel bed 50 ; the groove milling mechanism includes a first transmission assembly 10 and a groove milling assembly 20 installed on the first transmission assembly 10 .

[0022] The first transmission assembly 10 includes: a first movable seat 11 and a grinding frame 12; the first movable seat 11 is slidably connected to the grinding wheel bed 50, and the grinding frame 12 is installed on the first movable seat 11 and slidably connected to the first movable seat 11. The first movable seat 11 moves along the Z direction on the grinding wheel bed 50, and the grinding frame 12 moves along the X direction on the first movable seat 11; the X direction and the Z direction are as shown in FIG. Figure 1 In the direction shown in , the X direction is perpendicular to the Z direction. The linear motion of the first movable seat 11 on the grinding wheel bed 50 and the linear motion of the grinding frame 12 on the first movable seat 11 can be realized by a linear transmission method such as a threaded screw transmission, a gear rack transmission, etc. driven by a servo motor in the prior art, which will not be described in detail here. The servo motor has an encoder, and the encoder can be used to determine the movement of the milling groove assembly in the X direction and the Z direction. The first transmission assembly 10 drives the milling groove assembly 20 to move in the X direction or the Z direction.

[0023] The groove milling assembly 20 includes: an angle-adjustable milling cutter 21, a base 22, a rotating disk 23, and a driving source 24. Figure 2 As shown, the base 22 is installed at the front end of the grinding frame 12. The rotating disk 23 is rotatably connected to the base 22, and a worm gear can be used to realize the rotational connection between the two. The specific structure is not repeated here. The driving source 24 is installed on the rotating disk 23 and is connected to the milling cutter 21 through a transmission belt. The driving source 24 is used to drive the milling cutter 21 to rotate. When the milling cutter 21 needs to adjust the angle, the rotating worm drives the rotating disk 23 to rotate, and then the rotating disk 23 drives the milling cutter 21 and the driving source 24 to rotate, so as to adjust the angle of the milling cutter 21.

[0024] The head frame mechanism is installed on the workpiece bed 60. The head frame includes a second transmission assembly 30 and a head frame assembly 40. The second transmission assembly 30 includes: a second movable seat 31 and a head frame base 32. The second movable seat 31 is slidably connected to the workpiece bed 60, and the head frame base 32 is installed on the second movable seat 31 and slidably connected to the second movable seat 31. The second movable seat 31 moves along the X direction on the workpiece bed 60, and the head frame base 32 moves along the Z direction on the second movable seat 31. The linear motion mode of the second movable seat 31 on the workpiece bed 60 and the linear motion mode of the head frame on the second movable seat 31 can be realized by linear transmission modes such as linear motion modules, gear rack transmission, etc. in the prior art, which will not be elaborated here. The second transmission assembly 30 drives the head frame assembly 40 to move in the X direction or the Z direction.

[0025] The head frame assembly 40 is installed on the head frame base 32, and the head frame assembly 40 includes: at least two groups of output shafts 41 with different torques, and an encoder 42 correspondingly connected to each output shaft 41. The encoder 42 model is JKN-2C. The encoder 42 and the output shaft 41 are driven by a synchronous belt. A reducer 80 is connected to the encoder 42. The output shaft 41 is externally connected to a servo motor, and the servo motor drives the output shaft 41 to rotate. Among them, the ratio between the rotation speed of the encoder 42 and the rotation speed of the output shaft 41 is: 1:1. The output shaft 41 on the head frame base 32 drives the roller 70 to be milled to rotate along its axis. The one with a larger output torque in the output shaft 41 can drive a heavier roller 70. The one with a smaller output torque in the output shaft 41 can drive a roller 70 with a high rotation speed requirement and a slightly lighter weight.

[0026] Here’s how it works:

[0027] Based on the milling requirements of the roller 70 to be milled, the angle of the milling cutter 21 on the milling groove assembly 20 is adjusted respectively, and the movement of the milling groove assembly 20 in the X-axis direction and the Z-axis direction is controlled by the first transmission assembly 10. The output shaft 41 with different rotation speeds is selected, and then the milling groove assembly 20 operates the roller 70 to mill threads of different depths and different pitches at different positions on the roller 70. The milling groove assembly 20 is linked with the head frame assembly 40 to meet the processing requirements of different types of threads.
