Weld reinforcement grinding machine

Abstract

The invention provides a weld reinforcement grinding machine which comprises a support frame, a motor, a grinding wheel, a vertical position adjustment device and an elastic piece, wherein the vertical position adjustment device comprises a wheel shaft fixing piece and an elastic piece fixing piece which can slide relatively, and a limiting piece for limiting relative sliding of the wheel shaft fixing piece and the elastic piece fixing piece; the limiting piece is detachably connected with the wheel shaft fixing piece and / or the elastic piece fixing piece; the position of the lower end of the wheel shaft fixing piece in the vertical direction is changed in a manner that the wheel shaft fixing piece slides relative to the elastic piece fixing piece; the grinding wheel is driven by the motor; a shaft of the grinding wheel is fixed at the lower end of the wheel shaft fixing piece; the elastic piece fixing piece is fixedly connected with one end of the elastic piece; and the other end of the elastic piece is connected with the support frame. According to the weld reinforcement grinding machine, grinding reinforcement can be controlled.

Description

technical field [0001] The invention relates to a welding seam reinforcement grinding machine, which is applied in the field of metal welding. Background technique [0002] For the laying of high-voltage transmission and distribution system pipeline engineering, the welding quality of the pipeline is the most important part of the whole project quality, and the welding quality is also the most difficult to control. If the excess height exceeds the standard, it will seriously affect the welding quality and anti-corrosion effect, and the welding seam reinforcement will seriously exceed the standard The problem has not been fundamentally resolved. Manual welding reinforcement is a common phenomenon. For example, the welding reinforcement of some construction units stipulates that the welding reinforcement is 1.6mm. 3mm abounds, and some even as high as 5mm. [0003] As we all know, the two most important points in pipeline engineering are welding and anticorrosion. Pipe weld...
