Problems solved by technology

If dual-motor drive is used, that is, one motor is used to drive the gear on each side, when the system changes direction, due to the lateral gap between the gear and the rack, the feed movement will lag behind in the reverse direction, thus affecting the transmission accuracy.

Embodiment Construction

[0028] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0029] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

[0030] figure 1 It is a flowchart of the method module of the present invention. Such as figure 1 As shown, the control method of the present invention can be divided into two stages: interpolation operation processing and synchronization and anti-backlash control. In the interpolation operation processing stage, the open device controller separates the original interpolation operation into two parts, rough interpolatio...

Abstract

The invention discloses a four-motor drive synchronization and anti-backlash control method of a CRTS-III type track plate mold cleaning device, comprising the following steps: constructing an electrical connection structure of a four-motor drive system, and dividing four motors into two groups, wherein, The two motors in each group drive the main control axis and the controlled axis respectively; in the interpolation operation processing stage, the interpolation operation in the motion control of the controller is separated, so that the interpolation operation can be divided into rough interpolation and fine interpolation Two parts; in the stage of synchronous and anti-backlash control, for dual-axis synchronous control, the method of dual-axis parallel synchronous control is adopted, and the control object is the main control axis in the two groups of axes; and for anti-backlash control, dual-motor drive anti-backlash control is adopted method, the control object is the main control axis and the controlled axis driven by each group of motors. The control method of the invention has good synchronous effect and anti-backlash effect, and has sufficient driving force and flexible and open control mode at the same time.

Description

technical field [0001] The invention relates to the technical field of digital control for equipment operation control, in particular to a four-motor drive synchronization and anti-backlash control method of a CRTS-III track plate mold cleaning device. Background technique [0002] With the development of my country's high-speed rail technology, the production of CRTS-III track slabs has gradually transitioned from the pedestal method to the assembly line method, and comprehensive automated production has been applied. In the production process of the track slab, in view of the cement residue left in the mold after the track slab is demoulded and the need to clean the track slab before each slab, the existing production mode requires manual cleaning, which takes a long time and is labor-intensive and dust is harmful to the human body. larger. In the new mode of intelligent manufacturing, the mold cleaning station consists of six systems: closed cleaning room, mold positioni...
