Device for grinding inner wall of precisely-manufactured pipe fitting

Abstract

The invention discloses a device for grinding the inner wall of a precisely-manufactured pipe fitting. The device comprises an operation base, a left fixing plate and a right fixing plate are fixedlyconnected to the two ends of the top face of the operation base, a bearing seat is installed on the left fixing plate in a penetrating manner, and the pipe fitting to be ground is installed in the bearing seat in a rotating and penetrating manner. An automatic entering mechanism is arranged at the left side of the right fixing plate, the automatic entering mechanism is used for entering the innerwall of the pipe fitting to be ground, the automatic entering mechanism comprises a fixing plate fixedly connected to the left wall of the right fixing plate, a forward and reverse rotation motor is fixedly installed on the fixing plate, and the output end of the forward and reverse rotation motor is fixedly connected with a rotating rod. The automatic entering mechanism drives a grinding cylinderto automatically enter the pipe fitting to be ground, manual alignment is not needed, grinding is directly conducted while entering is conducted, operation is quite convenient, the labor intensity ofworkers is reduced, the inner diameters of the pipe fittings to be ground with different inner diameters can be ground through an adjusting mechanism, and operation is quite convenient.

Description

technical field [0001] The invention relates to the field of mechanical parts, in particular to a device for grinding the inner wall of precision-manufactured pipe fittings. Background technique [0002] In the equipment for internal grinding of seamless steel pipes in the metallurgical industry, a long shaft driven by a motor is commonly used, and the long shaft drives the grinding wheel to rotate and extend into the inner wall of the pipe, and the long shaft moves along the axial direction of the pipe to achieve grinding of the inner wall of the pipe. Improve the precision of the inner wall of the seamless steel pipe and improve the product quality. [0003] The traditional way of precision grinding the inner wall of pipe fittings has the inconvenience of moving the grinding facilities inside the pipe, which affects the grinding effect. For pipe fittings with different diameters, it is usually necessary to replace the long shaft with different specifications of grinding wh...

Problems solved by technology

[0004] so that the curved surfaces of the three strip-shaped abrasive stones can be close to the inner wall of the pipe fittings, which is suitable for pipe fittings with different apertures, but the inflated air bag is not safe enough. The force between them is too large, the inflated airbag will have an elastic effect, and it is not stable enough during the grinding process. In addition, in this patent, grinding and alignment are two separate steps, and there are many electrical equipments. Waste not cleaned up
