Problems solved by technology

Since the two motors are driven separately, it is difficult to accurately achieve real-time linkage positioning, especially the limitation on the transmission mechanism, it is difficult to develop towards miniaturization
A single multi-degree-of-freedom ultrasonic motor can only control a single-degree-of-freedom table, not a double-degree-of-freedom table

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] For the convenience of description, the "left", "right", "upper" and "lower" referred to below are consistent with the left, right, up and down directions of the drawings themselves, but do not limit the structure of the present invention. In addition, for the sake of brevity, the reading head and the grating ruler on the X-guiding guide are referred to as the first reading head and the first grating ruler, and the reading head and the grating ruler on the Y-guiding guide are referred to as the second reading head and the second grating ruler. The structure sliding in the Y direction is referred to as the first sliding structure, and the structure sliding in the Y direction is referred to as the second sliding structure.

[0022] exist figure 1 with figure 2 In the shown multi-degree-of-freedom X-Y workbench, the X-guiding r...

Abstract

The invention discloses an X-Y workbench with two degrees of freedom, and the workbench comprises a fixed structure, a first sliding structure, a second sliding structure, an ultrasonic motor with more than one degree of freedom, an ultrasonic motor control device with more than one degree of freedom, a bottom plate and a pressurizing device; the first sliding structure is arranged on the fixed structure, and the second sliding structure is arranged on the first sliding structure; one end of the ultrasonic motor with more than one degree of freedom is connected with the second sliding structure, and the other end of the ultrasonic motor with more than one degree of freedom is contacted with the bottom plate, and the ultrasonic motor with more than one degree of freedom maintains a certain pressure to the bottom plate through the pressurizing device; a workbench connecting plate is fixedly arranged on the second sliding structure; the ultrasonic motor control device with more than one degree of freedom controls the ultrasonic motor with more than one degree of freedom by signal excitation; and the ultrasonic motor with more than one degree of freedom controls the sliding of the workbench connecting plate in the X-Y direction by vibration. According to the X-Y workbench with two degrees of freedom, the precise positioning and the use of a single ultrasonic motor on the workbench with two degrees of freedom are realized.

Description

technical field [0001] The invention relates to a small X-Y workbench, in particular to an X-Y workbench with precise positioning. Background technique [0002] X-Y table is mainly used for two-degree-of-freedom plane motion positioning. At present, most of the X-Y worktables in the market are in the form of two motors driving the load to move along the X-guiding rail and the Y-guiding rail respectively. The specific form is composed of two independent and perpendicular guide rails, a transmission system and a workbench. The upper guide rail is equipped with a motor 1 to drive the workbench to move in the X direction, and the lower guide rail is supported by the base and is equipped with a motor 2 to drive. The upper guide rail, the motor 1 and the workbench move in the Y direction. Since the two motors are driven separately, it is difficult to accurately achieve real-time linkage positioning, especially the limitation on the transmission mechanism, which makes it difficul...
