[0020] The upper scraper 4 scrapes in a straight line to the left, and the lower scraper 5 scrapes in a clockwise swing arc, and the two form a shearing action towards each other.
[0021] The upper scraper 4 and the lower scraper 5 are different according to the specifications of the retaining ring. The edge contours are strictly designed and processed according to the cross-sectional contours of the retaining ring. When scraping, they are respectively located on the outer weld and inner weld of the steel ring retaining ring. The two can scrape the outer and inner weld slag in a shearing motion, and the lateral position, longitudinal position and spatial inclination of the upper scraper 4 and the lower scraper 5 can be adjusted separately to ensure that the edge fits the contour of the retaining ring so that the weld slag can be completely removed.
[0022] Working principle:
[0023] When the utility model is working, when the piston rod of the scraping power cylinder 301 pushes the push rod sleeve 302, the push rod sleeve 302 also pushes the sliding rod 303 to move upward, and the hinge point of the lower swing arm connected to the push rod sleeve 302 swings upward around the axis of the lower spindle 201, so that the large end of the lower swing arm drives the lower spindle 201 to rotate clockwise, and the hinge point of the upper swing arm connected to the sliding rod 303 also swings upward around the axis of the upper spindle 101, so that the large end of the upper swing arm drives the upper spindle 101 to rotate clockwise; in summary, when the piston rod of the scraping power cylinder is ejected, the upper spindle 101 and the lower spindle 201 can rotate clockwise synchronously.
[0024] The upper scraper is assembled in the upper tool seat 104 and is pressed by the upper scraper clamp 105. Since the front end of the upper spindle 101 is equipped with a gear fan 102, the gear fan 102 is engaged with the rack 103 installed on the rear end of the upper tool seat 104. Therefore, the clockwise rotation of the upper spindle 101 is converted into a horizontal leftward linear motion of the upper tool seat 104, so that the upper scraper and the weld on the outside of the workpiece produce relative slip, thereby scraping the welding slag outside the retaining ring.
[0025] The lower scraper is directly assembled in the special knife groove of the lower spindle 201 and is pressed by the lower scraper clamping plate 202. The clockwise rotation of the lower spindle 201 directly drives the lower scraper to swing clockwise around the axis, so that the lower scraper and the inside of the workpiece have relative slippage, thereby scraping the welding slag inside the retaining ring.
[0026] Similarly, when the piston rod of the scraper power cylinder 301 retracts, it pulls the push rod sleeve 302 downward, and the sliding rod 303 also moves downward under the action of the tension spring 306, thereby driving the upper swing arm and the lower swing arm to rotate counterclockwise around the upper spindle 101 line and the lower spindle 201 axis respectively, thereby driving the tool holder to move horizontally to the right, and the tool holder and the lower spindle 201 are reset respectively.
[0027] The parallel state between the lower swing arm 304 and the upper swing arm 305 can be adjusted. Due to different specifications of the steel ring retaining ring, tool wear, replacement of the pressure block, etc., the center distance between the upper spindle 101 and the lower spindle 201 changes, resulting in the lower swing arm 304 and the upper swing arm 305 not necessarily being parallel during operation. The adjustment top screw on the short swing arm 307 at the tail of the upper spindle 101 can be adjusted to make the double swing arms reach a parallel state again, thereby achieving synchronous rotation of the upper spindle 101 and the lower spindle 201.
[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
