Description

Technical Field

[0001] The utility model relates to the field of grinders, and more specifically to an automatic grinder for the end surface of a seamless steel pipe. Background Art

[0002] Seamless steel pipe is made of a whole round steel through holes. There is no weld on the surface of the steel pipe, which is called seamless steel pipe. According to the production method, seamless steel pipe can be divided into hot-rolled seamless steel pipe, cold-rolled seamless steel pipe, cold-drawn seamless steel pipe, extruded seamless steel pipe, jacking pipe, etc. According to the cross-sectional shape, seamless steel pipe is divided into round and special-shaped. Special-shaped pipes have square, oval, triangle, hexagon, melon seed, star, winged pipe and many other complex shapes. The maximum diameter is 900mm and the minimum diameter is 4mm. According to different uses, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes. Seamless steel pipes are mainly used as petroleum geological drilling pipes, cracking pipes for petrochemicals, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.

[0003] For example, the announcement number CN2818539Y discloses a reciprocating rail profiling grinder, which includes a grinding frame, and a grinding mechanism is arranged on the grinding frame. The special feature is that arc plates are connected to the bottom of the left and right support plates of the grinding frame, a connecting sleeve is arranged in the body, bearings are arranged at both ends of the connecting sleeve, a short shaft is arranged in the connecting sleeve, a guide end cover is arranged at the lower end of the body, a follower frame is arranged at the lower part of the long shaft, a spring is arranged between the follower frame and the guide end cover, roller mechanisms are arranged on both sides of the lower part of the follower frame, and an automatic reciprocating mechanism, a positioning mechanism and a rail clamping mechanism are also arranged on the grinding frame, and the automatic reciprocating mechanism is connected to the grinding mechanism. The advantages are: flexible handling, simple installation and operation, light weight, and a single person can realize multi-angle grinding of the rail head weld nodules.

[0004] It can be seen from the above-mentioned public scheme that currently, when limiting the position of a steel pipe, grinders mostly limit and fix the steel pipe in one position, and it is not easy to support and limit steel pipes of different lengths to the left and right, which causes the steel pipe to be easily tilted when placed, so that the grinding surface cannot be placed vertically, affecting the grinding effect. At the same time, when limiting, the limit device is mostly used to limit it manually, which is not only troublesome, but also has poor stability. Utility Model Content
