Description

Technical Field

[0001] The utility model relates to the technical field of manual surface grinders, in particular to an adjustable manual precision surface grinder. Background Art

[0002] A surface grinder is a type of grinder that grinds the flat or shaped surface of a workpiece. It mainly uses a grinding wheel to rotate and grind the workpiece so that it can achieve the required flatness. A manual surface grinder is a device that uses a manually-cranked grinding wheel for grinding. It is usually used for processing small precision workpieces. For example, a YC-M618J manual precision surface grinder in the prior art drives the grinding wheel to rotate by a handwheel set outside the grinder to grind the workpiece. Compared with an automatic grinder, it can perform fine grinding according to the operator's control, thereby improving the precision of workpiece processing.

[0003] According to the patent publication number CN115519418A: The present invention discloses an adjustable manual precision surface grinder, including a surface grinder body, a baffle plate is provided on one side of the grinding wheel outer cover, a horizontal telescopic assembly is provided on the outer wall of the grinding wheel outer cover, a frame box is provided on the feeding side of the baffle plate, a scraper frame and a transmission motor are provided inside and outside the baffle plate respectively, a suction cone cover is fixedly inserted inside the opening of the frame box, and a scraper assembly is provided on the scraper frame. The horizontal position of the baffle plate is adjusted by adjusting bolts, sleeve plate columns and adjusting sleeves to achieve adaptive adjustment of the distance between the baffle plate and the grinding wheel; the water pump body flushes the baffle plate and the suction cone cover through the liquid guide pipe and the water nozzle, and the rotation of the scraper frame drives the main scraper plate, the outer scraper plate and the inner scraper plate in turn to scrape and clean the splashing grinding materials on the inner curved surface of the baffle plate, the outer surface of the suction cone cover and the inner surface, so that the splashing grinding materials that are about to solidify on the baffle plate and the suction cone cover can be cleaned in time.

[0004] However, the workbench in the above patent needs to be manually pushed to move the workpiece to the position of the grinding wheel, so it is not convenient to operate. In addition, the material baffle plate in the above patent can only be raised and lowered vertically. Therefore, when the grinding wheel needs to move forward to process the workpiece, the material baffle plate is easily stuck by the grinding wheel as the workbench moves, thereby causing the workbench to be unable to move, making it inconvenient to move and process the workpiece.
