Grinding Feed Mechanism of Composite Tube Inner Weld Grinding Machine

Abstract

The invention discloses a grinding feeding mechanism of a composite tube inside weld grinding machine. The grinding feeding mechanism comprises a mounting seat and a mounting support arranged on the surface of the mounting seat and further comprises a movable seat, a movable mechanism, a feeding mechanism and a grinding head lifting fine-adjusting mechanism. The movable seat is arranged on the mounting support through the movable mechanism. The feeding mechanism is arranged on the upper portion of the movable seat through the grinding head lifting micro-adjusting mechanism. A composite tube inside weld is ground through cooperation among the movable seat, the movable mechanism, the feeding mechanism and the grinding head lifting micro-adjusting mechanism, grinding speed is high, and grinding precision is high. The movable seat is driven by the movable mechanism to do reciprocating motion, the effect of fast tool setting and fast grinding is achieved by combining the grinding head lifting micro-adjusting mechanism, a tool setting base plate and a universal contour wheel, and convenience and fastness are achieved.

Description

technical field [0001] The invention relates to a compound pipe internal weld grinding machine, in particular to a compound pipe internal weld grinding machine grinding feeding mechanism. Background technique [0002] Composite pipes are generally two layers, in which a corrosion-resistant metal pipe is placed inside the other metal pipe, and the two are fixed into one structure by expansion and end welding. [0003] After the two metal pipes are welded, part of the welded part needs to be turned off, and a certain step is left; the step needs to be manually ground at the welded part to meet the installation requirements of the pipe fittings. Due to the low accuracy of manual grinding, it is easy to scratch the inner liner. After scratching the inner liner, it needs to be re-welded and re-grinded, which affects the efficiency of the finished product. [0004] Moreover, the cost of manual grinding is high, the grinding precision is low, and the grinding time is long; manual ...

AI Technical Summary

Problems solved by technology

Due to the low accuracy of manual grinding, it is easy to scratch the inner liner. After scratching the inner liner, it needs to be re-welded and re-grinded, which affects the efficiency of the finished product.

[0004] Moreover, the cost of manual grinding is high, the grinding precision is low, and the grinding time is long; manual grinding is dangerous, and the pass rate of the composite pipe after grinding is low. If the inspection fails, it needs to be re-grinded, which affects the efficiency of the product leaving the factory.
