Abstract
The utility model discloses a polishing machine for the inner diameter of a square pipe. The polishing machine comprises an impact motor, a handle and a control switch, wherein a telescopic connecting rod is connected to a shaft of the impact motor; and a triangular column-shaped grinding wheel is arranged on the connecting rod. According to the polishing machine, the motion form of an impact drill is simulated, the adjustment length of the telescopic connecting rod is increased, and a cylindrical grinding wheel used in the past is changed into the existing triangular column-shaped grinding wheel, so that a bump at the joint of two vertical planes can be directly polished, the tissue structure of the square pipe is not damaged, the service life of the square pipe is not influenced, the resource waste is greatly reduced and the manpower and material resources are saved.
Description
Technical field
The utility model relates to a kind of square tube internal diameter sanding machine.
Background technology
In traditional foundry industry, the casting motor housing is very simple, and external form is smooth, structure is tight.In the casting cycle owing to various reasons cause a plurality of small embossments of internal diameter of the pipeline, two vertical surface intersections especially.Need polish smooth, a lot of enterprises send product into machining center, carry out after-treatment, cost lot of manpower and material resources, the wasting of resources.
Summary of the invention
The purpose of the utility model is to provide a kind of polishes simply, fast, need not spend the square tube internal diameter sanding machine of lot of manpower and material resources.
The purpose of the utility model realizes through following technical scheme: this square tube internal diameter sanding machine comprises impact type motor, handle, gauge tap, is connected with telescopic pitman on the axle of impact type motor, and pitman is provided with triangular prism molding sand wheel.
The forms of motion of the utility model simulation percussion drill; Increase telescopic pitman and regulate length, the column type emery wheel that uses is in the past changed into present triangular prism molding sand wheel, can directly polish the convexity of two vertical surface intersections; Do not destroy the institutional framework of square tube; Can not influence its service life yet, and reduce the wasting of resources widely, use manpower and material resources sparingly.
Description of drawings
In conjunction with accompanying drawing the utility model is done further to describe in detail.
1, impact type motor 2, pitman 3, triangular prism molding sand wheel 4, handle 5, gauge tap
