Description
Technical Field
The utility model relates to a simple scraping/grinding device, and belongs to the technical field of mechanical assembly.
Background
At present, the contact precision and the geometric precision of a high-precision guide rail pair and a particularly important joint surface in the mechanical industry are ensured by adopting a scraping/lapping mode, and the scraping/lapping mode can increase the contact area and improve the lubrication condition, so that the matching rigidity, the lubrication performance and the service life of a machine tool are improved. The scraping and lapping are methods of coating developer on the joint surface of the fixed base member or the movable member, making the developer move or rotate relatively by the action of external force to copy the contact precision, then removing the high point by a scraper, and repeating the operation to reach the requirement of the shape and position tolerance. In actual operation, the self weight of most scraping/lapping workpieces is too large, the workpieces cannot be moved manually, and uneven stress on the joint surfaces is caused by non-parallel movement of the workpieces due to movement of devices such as pulleys and crown blocks, so that contact false images are generated, and the scraping precision is affected.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a simple scraping/lapping device, which is characterized in that a fixed supporting point is formed by connecting a connecting rod assembly with a fixed base member, and the relative movement of a workpiece to be scraped/lapped is completed by driving the movement of a moving member through the position change of a waist-shaped hole on a movable straight pin and a channel steel connecting rod, so that the problem that the relative movement of the fixed base member and the moving member is difficult or contact false images are caused during scraping/lapping is effectively solved.
The technical scheme adopted for solving the technical problems is as follows: the simple scraping/grinding device comprises a channel steel connecting rod and a rotating rod, wherein the lower end of the channel steel connecting rod is fixedly connected with the upper end of the rotating rod to form a connecting rod assembly, a through hole is formed in the center of the upper end of the channel steel connecting rod, and a waist-shaped hole is formed in the channel steel connecting rod below the through hole; a pin hole is formed in the center of the upper end of the fixed base piece, the pin hole corresponds to the through hole of the channel steel connecting rod, and the fixed straight pin is inserted into the through hole of the channel steel connecting rod and the pin hole of the fixed base piece in a matched mode; the movable piece is arranged in the fixed base piece, a pin hole is formed in the center of the movable piece, the movable straight pin is matched with the waist-shaped hole penetrating through the channel steel connecting rod and is inserted into the pin hole of the movable piece, and the connecting rod assembly is connected with the movable piece.
The beneficial effects of the utility model are as follows: the utility model can effectively solve the problem that the relative movement of the base part and the corresponding part is difficult or contact false is caused during scraping/lapping, the connecting rod component is arranged on the base part and the corresponding part, the scraping/lapping precision can not be influenced by directly using the device for scraping/lapping, and meanwhile, the device has simple structure, convenient operation and low cost.
