Automatic weld joint back chipping machine

Abstract

The invention discloses an automatic weld joint back chipping machine. The automatic weld joint back chipping machine comprises a machine frame and a grinding wheel, fixed bearing seats are arranged at the two ends of the machine frame, a rotating shaft is connected between the two fixed bearing seats, a driving motor is installed on the rotating shaft through a supporting seat, a pitching adjusting seat is fixedly connected to one end of the rotating shaft, an adjusting nut seat with an adjusting lead screw is hinged to the interior of the pitching adjusting seat, an adjusting bearing seat isinstalled at one end of the adjusting lead screw, the adjusting bearing seat is hinged to a supporting frame installed on the machine frame, the tail end of the adjusting lead screw is connected withan adjusting motor used for adjusting the pitching angle of the supporting seat relative to the machine frame, and an X-axis adjusting assembly and a Y-axis adjusting assembly for adjusting the distance between the grinding wheel and a weld joint on the X-axis and the Y-axis are sequentially arranged between the supporting seat and the driving motor. Through the arrangement of the X-axis adjusting assembly, the Y-axis adjusting assembly and the adjusting motor, the distance between the grinding wheel and a machined object, the grinding depth and the pitching angle can be automatically adjusted, the manual operation intensity is reduced, and the machining efficiency can be improved.

Description

technical field [0001] The invention relates to a machine tool or device for grinding or polishing belts, in particular to an automatic welding seam cleaning machine. Background technique [0002] Root cleaning refers to: For fully penetration welds formed by double-sided welding with high quality requirements (non-destructive testing such as UT and RT testing are required after welding), before welding one side to the other side after welding , the process of cleaning the root of the completed weld from the reverse side using appropriate tools. The equipment for cleaning the root of the weld is also called a root cleaning machine, which is mostly used for diameter pipes, storage tank welds, etc., and is ground with a grinding wheel. [0003] The existing root cleaning machine is manually operated according to the position of the weld. During processing, the position of the grinding wheel needs to be adjusted along the weld, such as the distance between the grinding wheel a...

Problems solved by technology

[0003] The existing root cleaning machine is manually operated according to the position of the weld. During processing, the position of the grinding wheel needs to be adjusted along the weld, such as the distance between the grinding wheel and the object to be processed, the grinding depth and the pitch angle. Some technical solutions are manually adjusted, which not only requires high operating intensity, but also has low processing efficiency
