After being limited, the center plate cannot drive the I-plate to move, thereby further improving the clamping effect.

[0016] (3) The inner hole grinding device for valve production and processing drives the scraper to move through the movement of the connecting plate. The scraper moves to scrape the welding slag accumulated inside the welding slag box to the feed box, reducing the time of manual cleaning, improving work efficiency, and avoiding the situation where the filter plate is blocked by excessive accumulation of welding slag. The downward movement of the slide bar drives the vertical plate to move downward, and the downward movement of the vertical plate drives the pressure plate to move. At the same time, the pressure plate moves to compact the welding slag inside the waste box, realizing centralized storage of welding slag, which is convenient for subsequent recycling and treatment. For some welding slag that needs to be recycled and reused, it helps to reduce waste, reduce production costs, and keep the work area clean. BRIEF DESCRIPTION OF THE DRAWINGS
