Problems solved by technology

[0002] Common gantry-type drive mode: driven by a single-sided integrated module or ball screw structure, the obvious disadvantages are low speed, low resolution of running accuracy, and easy to cause distortion of the gantry-type structure; Driven by motor, the disadvantage is that not only it is easy to cause distortion and deformation of the gantry structure, but also it is easy to generate large vibration during high-speed operation of the equipment, which directly affects the instability of scanning accuracy

Abstract

The invention discloses a double-drive structure for a stepping shaft of an ultrasonic scanning microscope and an adjusting method for the double-drive impulse parameter matching. The double-drive structure comprises a left driving unit, a right driving unit, a front support beam, a back support beam and an X-direction cross beam, wherein the front support beam and the back support beam are butted with the left driving unit and the right driving unit on the front side and the rear side respectively; the X-direction cross beam is connected with the left driving unit and the right driving unit. According to the invention, the double-side drive is adopted, an overlapping manner is adopted to form a gantry type architectural pattern at the high position, the problems that a gantry type architecture is twisted and deformed and greater vibration influence is generated as the single-side drive is adopted are avoided, the precision requirement for the machining of critical parts is easy to met, and the rigidity requirement of the overall architecture is ensured.

Description

technical field [0001] The invention relates to a driving structure of a stepping shaft of an ultrasonic scanning microscope, in particular to a double-driving structure of a stepping shaft of an ultrasonic scanning microscope and an adjustment method for matching pulse parameters of the double-driving. Background technique [0002] Common gantry-type drive mode: driven by a single-sided integrated module or ball screw structure, the obvious disadvantages are low speed, low resolution of running accuracy, and easy to cause distortion of the gantry-type structure; The disadvantage of motor driving is that it is not only easy to cause distortion and deformation of the gantry structure, but also makes it easy to generate large vibrations during high-speed operation of the equipment, which directly affects the instability of scanning accuracy. Contents of the invention [0003] The purpose of the present invention is to provide a dual-drive structure of the stepping shaft of a...
