Description

Technical Field

[0001] The present invention relates to the technical field of turning devices, and specifically relates to a movable turning device for the shoulder end face of a rolling mill motor shaft. Background Art

[0002] Due to the running wear of the thrust pad on the thrust bearing in contact with the shoulder end face of the rolling mill motor shaft, there are unevenness and grooves on the shoulder end face of the motor shaft, which need to be repaired and leveled. The past method was to remove the upper bearing cover, upper shaft tile and thrust tile of the thrust bearing, expose the upper half of the shoulder end face of the motor shaft, start the variable frequency speed regulation synchronous rolling mill motor to rotate, and polish with sandpaper and oilstone, which was time-consuming and laborious, and could not achieve the flatness required by the technical requirements.

[0003] Therefore, the Chinese patent with the publication number of "CN102303130B" discloses "a movable turning device for the shoulder end face of a rolling mill motor shaft". Its main structure includes a transverse feed device, a longitudinal feed device, a device in which the straight line connecting the cutting tool tip and the center of the motor shaft is parallel to the axis of the lead screw II, including a rotating bottom plate and a fixed bottom plate. The transverse feed device and the longitudinal feed device are fixed on the rotating bottom plate. The fixed bottom plate is installed on the plane of the bearing seat. One end of the rotating bottom plate is rotatably connected to one end of the fixed bottom plate. An angle adjustment device is installed between the rotating bottom plate and the fixed bottom plate. A fastening screw locking device is provided at the other end of the rotating bottom plate and the other end of the fixed bottom plate. This movable turning device for the shoulder end face of a rolling mill motor shaft is installed on the plane of the bearing seat, and the fixed bottom plate is fixed by using the screw holes on the plane of the bearing seat, which is convenient for disassembly and installation. A transverse feed device and a longitudinal feed device are installed on the movable turning device for the shoulder end face of a rolling mill motor shaft. By adjusting the device in which the straight line connecting the cutting tool tip and the center of the motor shaft is parallel to the axis of the lead screw II, turning processing of the shoulder end face of the rolling mill motor shaft can be realized on-site under the working condition when the motor rotates.

[0004] However, in actual work, due to the bottom fixed connection relationship, the longitudinal feed device of the above-mentioned movable turning device for the shoulder end face of a rolling mill motor shaft cannot rotate. Therefore, the turning head cannot be adjusted in angle in the rotating state. At this time, the turning head must be installed radially with respect to the shaft body, and at this time, the installation accuracy requirements for the equipment are relatively high, and it is easy to cause accuracy changes in shaft body turning due to insufficient installation accuracy, and accuracy deviation is likely to occur.

First, the outer rotating shell 61 is rotated so that the center line of the rectangular hollow body 51 is radially aligned with the motor shaft shoulder, and then the hydraulic device is started to allow high-pressure liquid to enter the interior of the movable cavity 67 of the No. 2 component and generate liquid pressure on the No. 1 inner movable plate 610. At this time, the liquid pressure and the No. 2 coil spring 61 2, the No. 2 coil spring 612 will press against the outer circumference of the inner rotating column 64 with a certain pressure, so that the outer rotating shell 61 is locked on the periphery of the inner rotating column 64, and the No. 2 rotating cap 79 is rotated in a directional manner, thereby driving the No. 2 external threaded rod 78 to rotate.
