Description

Technical Field

[0001] The invention relates to the technical field of servo motor testing tooling, and in particular to a positioning tooling for convenient servo motor testing. Background Art

[0002] The servo motor is the core component of the drive system. It is particularly important to conduct comprehensive and accurate performance tests on the servo motor during its production, research and development, and maintenance. The servo motor test includes static characteristic test, dynamic response test, load capacity test and other aspects. These tests require the servo motor to be accurately and stably positioned on the test bench to ensure the accuracy and reliability of the test data. However, there are many shortcomings in the traditional servo motor test positioning tooling. On the one hand, due to the wide variety of servo motors and their different sizes and specifications, traditional tooling is often difficult to adapt to servo motors of different models, resulting in inaccurate positioning and large deviations in test data. On the other hand, the traditional tooling is complicated to operate and requires a lot of manpower and material resources for installation and adjustment, which not only reduces the test efficiency but also increases the test cost.

[0003] In order to solve the above problems, some improved servo motor test positioning tools have appeared on the market. These tools have improved the versatility and adaptability of the tools by adding adjustable clamping mechanisms. However, these tools still have problems such as insufficient ease of operation and insufficient positioning speed, and cannot meet the high requirements of servo motor testing in the field of modern industrial automation.
