Description

Technical Field

[0001] The utility model relates to the technical field of milling machines, in particular to a milling cutter transmission device of the milling machine. Background Art

[0002] The traditional milling machine's milling cutter transmission mechanism is generally a direct flange suspension rigid connection between the servo motor and the small slider ball screw of the milling machine. This connection structure generates large vibrations (generating a vibration value of 5-6MM / S) due to the milling process of the milling machine and the bending of the casting, which is then transmitted to the servo motor, which is easy to cause positioning deviation of the servo motor.

[0003] In addition, long-term vibration can easily cause the cone sleeve that fixes the servo motor to crack, causing the servo motor to fall off, ultimately resulting in poor quality of the produced pipes and low yield rate. Utility Model Content

[0004] The utility model provides a milling cutter control servo transmission device for a milling machine, which can effectively reduce the vibration of a servo motor, achieve stable processing quality of pipes of the milling machine, improve the yield rate, and reduce the equipment failure maintenance rate.

[0006] Furthermore, the ball screw transmission mechanism is connected to a milling cutter assembly.

[0007] Furthermore, the servo motor is mounted on a mounting bracket.

[0008] Furthermore, the tire coupling is an LLB type skeleton tire coupling.

[0009] Furthermore, the star coupling is an XL-S1 type star elastic coupling.

[0010] Furthermore, the milling cutter assembly includes an axle seat, a cutter shaft and a milling cutter; the cutter shaft is installed on the axle seat, and one end of the cutter shaft is connected to the ball screw transmission mechanism, and the other end is connected to the milling cutter.

It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0015] like Figure 1 As shown, the servo transmission device for controlling the milling cutter 9 of the milling machine of the present invention comprises a servo motor 1, a star coupling 2, a cross universal telescopic coupling 3, a tire coupling 4 and a ball screw transmission mechanism 5. The servo motor 1 is mounted on a mounting support 6, one end of the star coupling 2 is connected to the servo motor 1, and the other end is connected to the cross universal telescopic coupling 3; the other end of the cross universal telescopic coupling 3 is connected to the tire coupling 4, and the tire coupling 4 is connected to the ball screw transmission mechanism 5, and the ball screw transmission mechanism 5 is connected to the milling cutter assembly.

[0016] Since the star coupling 2 uses engineering plastic as elastic element for shock absorption, it has the advantages of compact size, small inertia, wear resistance, buffering and maintenance-free; the cross-axis universal telescopic coupling can effectively ensure the equal angular velocity of the rotation operation and the synchronous rotation between the main shaft and the slave shaft, thereby ensuring that the position of the servo motor 1 end remains unchanged; and the tire body of the tire coupling 4 has high flexibility, large damping, large compensation amount, simple structure and easy assembly.

[0017] Therefore, by setting up a structure in which the servo motor 1 is connected to the star coupling 2, the star coupling 2 is connected to the cross universal telescopic coupling 3, the cross universal coupling is connected to the tire coupling 4, and the tire coupling 4 is connected to the ball screw transmission mechanism 5, the ball screw transmission mechanism 5 drives the milling cutter 9 to run, so that the vibration value of the servo motor 1 is reduced to 0.1MM / S, achieving stable transmission; at the same time, the position of the servo motor 1 and the position of the main machine milling cutter 9 are automatically adjusted through the telescopic cross universal telescopic coupling 3, ensuring that the position of the servo motor 1 end remains unchanged.

[0018] Among them, the tire coupling 4 is an LLB type skeleton tire coupling, the cross universal telescopic coupling 3 is a customized small cross-axis universal telescopic coupling, and the star coupling 2 is an XL (S1) type star elastic coupling.

[0019] The milling cutter assembly includes an axle seat 7, a cutter shaft 8 and a milling cutter 9, wherein the cutter shaft 8 is mounted on the axle seat 7, and one end of the cutter shaft 8 is connected to the ball screw transmission mechanism 5, and the other end is connected to the milling cutter 9. The ball screw transmission mechanism 5 drives the cutter shaft 8 to rotate, thereby driving the milling cutter 9 to rotate.

[0020] In summary, the milling cutter 9 control servo transmission device of the milling machine of the utility model has the following advantages:

[0021] 1. By setting a structure in which a servo motor 1 is connected to a star coupling 2, the star coupling 2 is connected to a cross universal telescopic coupling 3, the cross universal coupling is connected to a tire coupling 4, and the tire coupling 4 is connected to a ball screw transmission mechanism 5, the ball screw transmission mechanism 5 drives the milling cutter 9 to run, so that the vibration value of the servo motor 1 is reduced to 0.1MM / S, the vibration of the servo motor 1 is effectively reduced, stable transmission is achieved, the milling machine pipe processing quality is stable, the yield rate is improved, and the equipment failure maintenance rate is reduced.

[0022] 2. By setting the cross universal telescopic coupling 3, the position of the servo motor 1 and the position of the milling cutter 9 of the main machine are automatically adjusted through the extension and retraction of the cross universal telescopic coupling 3, ensuring that the position of the servo motor 1 end remains unchanged, thereby effectively solving the problem of positioning deviation of the servo motor 1.
