Description

Technical Field

[0001] The present invention relates to the technical field of angle measuring slides, in particular to an electric angle measuring slide. Background Art

[0002] A goniometer slide is a combination of a goniometer and a slide. It provides a stable moving environment, allowing angle measurement of a target object to be performed in conjunction with the goniometer. It is commonly used in applications requiring precise angle adjustment and measurement, such as optical instruments, measuring devices, inspection equipment, and semiconductor manufacturing equipment.

[0003] In the field of angle measurement equipment, traditional angle measurement slides typically use worm gear or gear transmission mechanisms. While these transmission methods can achieve angle adjustment, they suffer from low transmission efficiency, high friction losses, and short service life. This makes it difficult to ensure accuracy and reliability, especially in high-frequency and high-precision applications. Furthermore, the guide systems of traditional slides are often relatively simple, prone to motion instability and precision deviations. This is especially true during long-term, high-frequency motion, where wear leads to reduced accuracy. To prevent damage caused by excessive deflection, existing technologies typically rely on mechanical limiters, but these devices are prone to errors or damage, making it difficult to provide effective protection.

[0004] To this end, the present invention provides an electric goniometer slide to solve the above problems. Summary of the Invention

[0015] The present invention provides an electric angle measuring slide.

The screw drive has higher precision than the traditional worm gear drive system, can provide better control and less friction loss, and is particularly suitable for high-precision measurement applications.

[0025] In this embodiment, the linear guide assembly 5 is provided to ensure that the screw nut 4 can move back and forth linearly along the screw 3, thereby ensuring the moving state of the screw nut 4.

[0026] A mounting groove 16 is defined on the top cover 7 , the connecting assembly 6 is mounted in the mounting groove 16 , and a cover plate 10 is fixed to a position on the top wall of the top cover 7 corresponding to the mounting groove 16 .
