A floating grinding head mechanism

Abstract

The invention discloses a floating grinding head mechanism, which includes a frame body, an upper cover, a lower cover, a lower adjustment mechanism, a push head, a first spring, a limit mechanism, a floating plate, a grinding head mechanism, and a gear mechanism. When the grinding head is subjected to uneven force due to the unevenness of the inner wall of the casting tube, the ball head fixedly connected with the polished rod will generate a thrust on the floating plate. The push head is deflected, so the polished rod fixed to the grinding head can slide along the rubber plug and send deflection, thereby protecting the grinding head from breaking. The structure of the device is simple, and the design of the floating plate can prevent the grinding head from being broken due to force. At the same time, the design of multiple sets of grinding heads can effectively improve the grinding efficiency and can adapt to cast pipes of different diameters.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a floating grinding head mechanism. Background technique [0002] Urban construction is based on planning, and through construction projects, the urban living environment is transformed, and various material facilities in the urban system are constructed, including water supply system construction, road construction, etc., among which the construction of water supply pipe network is particularly important. As an important part of the urban water supply network, the cast pipe plays an important role in people's daily life, and its quality directly affects the basic life of the residents. Therefore, multiple processes are required to ensure its quality quality. In order to ensure the anti-corrosion performance of the cast pipe, it is necessary to spray an anti-corrosion coating on its interface when processing the cast pipe. Before spraying the anti-corrosion coating, it is necessary to gri...

AI Technical Summary

Problems solved by technology

The traditional method is to install a fixed electric grinding head, and the motor drives the grinding head to rotate to grind the inner wall of the cast pipe. Since the fixed-installed grinding head is prone to breakage when the inner wall is obviously uneven, resulting in shutdown, etc. Problems that affect the production rhythm, and the efficiency of grinding with a single grinding head is also relatively low
