Spindle driving device of vertical type powerful spinning machine and driving method

Abstract

The invention discloses a spindle driving device of a vertical type powerful spinning machine and a driving method. The device comprises a lathe bed, a spindle, multiple groups of drive motors and a control system used for controlling the drive motors, wherein the spindle is vertically mounted on the lathe bed; the multiple groups of drive motors are vertically mounted on the lathe bed; a first belt wheel is mounted at the output end of each group of drive motor; a second belt wheel is mounted at the bottom of the spindle; each first wheel and the second belt wheel are connected through a flexible transmission body; diameters of the positions, corresponding to different transmission bodies, of the second belt wheel are different, or diameters of the multiple first wheels are different. The multiple groups of drive motors which are vertically mounted are adopted as power sources for high-speed and low-speed switching of the spindle, a servo system can switch different motors rapidly, and high-speed and low-speed switching of the spindle is rapid; meanwhile, a horizontal transmission can be omitted, and the cost is saved.

Description

Technical field [0001] The invention relates to a vertical powerful spinning machine, in particular to a main shaft driving device and a driving method of the vertical powerful spinning machine. Background technique [0002] In the spinning forming industry, to realize rough and fine flexible processing of different types of parts, the spindle of the spinning machine needs to rotate at different speeds. Most of the existing spinning machines use a motor connected to a horizontal gearbox, and the horizontal gearbox is used to convert the high and low speed of the main shaft. The output end of the gearbox is connected to the gear inside the bed to connect the horizontal gear of the motor. The power is transferred to the spindle after the rotation is converted into a form of rotation. The following problems exist in the form of horizontal gearbox: [0003] 1. After multiple sets of gear drives, the mechanical efficiency of the spinning machine will be greatly reduced; [0004] 2. The...

AI Technical Summary

Problems solved by technology

[0003] 1. After multiple sets of gear transmission, the mechanical efficiency of the spinning machine will be greatly reduced;

[0004] 2. The horizontal gearbox switches between high and low speeds through internal gear displacement, which has the problem of slow switching between high and low gears of the spindle speed and low efficiency;

[0005] 3. Assembling and debugging multiple sets of transmission gears inside the bed is time-consuming and laborious, and maintenance is difficult
