Description

Technical Field

[0001] This utility model relates to the field of robotic arm connection technology, specifically a connection device with flexible support. Background Technology

[0002] Scraping is a manual process that uses a scraper, a reference surface, measuring tools, and a colorant to scrape the metal surfaces of two moving products, or the contact surfaces connecting two products. By applying a colorant to the metal surface, minute high points are identified, and then the high points are scraped using a scraper. This process improves the dimensional and positional accuracy of the metal surface, while also improving the lubrication of the contact surfaces of the workpieces.

[0003] To reduce the intensity of manual labor and improve the working environment for workers, scraping equipment has been developed and installed on robotic arms to replace manual scraping. However, since the robotic arm is a rigid structure, it cannot apply flexible pre-pressure like a human can when scraping, which makes it easy for the robotic arm to over-scrape the product surface. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a connecting device with flexible support, which provides flexible counterforce in multiple directions for the scraper, so as to solve the problem of excessive rigidity when using the robotic arm directly, and improve the accuracy and scraping effect.

One end of the first threaded post is fixed to the second support plate, and the other end passes through the first support plate and is threadedly engaged with the nut. The first rectangular spring is sleeved on the first threaded post.

[0012] Furthermore, the third flexible support includes a cylindrical sleeve, a second threaded post, a support block, and a second rectangular spring.

[0015] Furthermore, it also includes an air blowing assembly, which is mounted on the second support plate and is used to blow away the debris scraped off by the scraper.

[0016] Compared with the prior art, the present invention has the following beneficial effects:
