The main function of the upper tool holder clamping mechanism 3 is to serve as the mounting carrier of the upper scraper 7 and guide its lateral scraping movement. The spindle position of the upper pressure seat 302 is provided with a mounting position, and an upper spindle assembly 2 is installed in the mounting position. The upper spindle assembly 2 includes an upper spindle 201, an upper bearing group 202 and a gear fan 203. The gear fan 203 is installed at the front end of the upper spindle 201, and the gear fan 203 is meshed with the rack 304. The upper spindle assembly 2 is supported by the lower bearing group 502, and the gear fan 203 is installed at the front end. The main function of the upper spindle assembly 2 is to transmit The scraping power of the upper scraper 7, the lower spindle assembly 5 is fixedly installed in the spindle mounting position of the frame 1, the lower spindle assembly 5 includes a lower spindle 501 and a lower bearing group 502, the lower scraper 8 is assembled in the knife groove of the lower spindle 501, the main function of the lower spindle assembly 5 is to serve as the installation carrier of the lower scraper 8 and convert its circular swinging scraping movement, the scraping power transmission mechanism 4 is installed in the middle of the frame 1, the scraping power transmission mechanism 4 includes a scraping power cylinder 401, a double rocker mechanism 402 and a telescopic sleeve 403, and the main function of the scraping power transmission mechanism 4 is to provide scraping power and power transmission conversion.

[0022] The scraping power of the scraping tool is driven by the scraping power cylinder 401 via the double rocker mechanism 402; by replacing the upper scraper 7, the lower scraper 8 and the lower pressure block 103 and the upper pressure block 305 that clamp the workpiece, it can meet the scraping needs of steel ring retaining rings of various specifications, and the height and spatial angle of the upper scraper 7 and the lower scraper 8 can be adjusted after wear; the upper scraper 7 and the lower scraper 8 are different according to the specifications of the retaining ring, and the edge profile is strictly designed according to the cross-sectional profile of the retaining ring, assisted by the adjustment mechanism of the upper scraper 7 and the lower scraper 8, which can ensure the complete removal of welding slag.

[0023] The upper scraper 7 performs straight-line scraping and is assembled in the upper tool holder 303. When the scraping power cylinder 401 pushes the double rocker mechanism 402, the upper spindle 201 and the lower spindle 501 rotate at the same time, and the gear fan 203 at the front end of the upper spindle 201 engages with the rack 304 installed on the upper tool holder 303, thereby pushing the upper tool holder 303 to translate under the guidance of the guide column 306, so that the upper scraper 7 and the outside of the workpiece produce relative sliding, thereby scraping the welding slag outside the retaining ring.

[0024] The lower scraper 8 performs scraping in a swinging arc and is directly assembled in the knife groove of the lower spindle 501. The scraper power cylinder 401 pushes the double rocker mechanism 402 to rotate the lower spindle 501 and make the lower scraper 8 slide relative to the inside of the workpiece, thereby scraping the welding slag inside the retaining ring.

[0025] Working principle:

[0026] When the utility model is working, the large end of the steel ring retaining ring is facing outward and placed on the roller seat 601 of the feeding rack 6. The roller seat 601 and the moving seat 602 are manually pushed forward. After they are in place, the lifting cylinder 603 is actuated to drive the roller seat 601 to descend, and the workpiece is inserted into the lower pressing seat 102 of the main machine and fits with the lower pressing block 103. Then the clamping cylinder 301 is actuated to drive the upper pressing seat 302 and the upper spindle assembly 2 to descend together. The workpiece is clamped by the interaction between the upper pressing block 305 and the lower pressing block 103. After clamping, the scraping power cylinder 401 is ejected to push the upper and lower white stems of the double rocker mechanism 402 to rotate around the axis of the upper spindle 201 and the lower spindle 501 respectively, thereby driving the upper spindle 201 and the lower spindle 501 Rotation, the rotation of the upper spindle 201 is converted into linear motion of the upper tool holder 303 through the meshing transmission of the gear fan 203 and the gear 304, and is guided by the guide column 306. The upper scraper 7 scrapes the welding slag on the outside of the retaining ring in a linear trajectory as the upper tool holder 303 translates, and the lower scraper 8 directly scrapes the welding slag on the inner surface of the retaining ring in a circular arc trajectory as the lower spindle 501 rotates. After the slag scraping is completed, the clamping cylinder 301 and the scraping power cylinder 401 are retracted, the upper tool holder clamping mechanism 3 is lifted, and the double rocker mechanism 402 drives the upper spindle 201 and the lower spindle 501 to reset; finally, the lifting cylinder 603 is lifted to lift the roller seat 601. After lifting into place, the moving seat 602 is manually pulled out to take out the workpiece to complete the unloading.
