Back gouging device at joint of circular reinforcing rib and barrel

Abstract

The invention relates to a back gouging device for the joint of a circular reinforcing rib and a barrel. The back gouging device comprises a rack, a back gouging device and a back gouging device, wherein the rack is provided with a bent part and a platform part; the barrel profiling part comprises a driving part and a driving wheel; the driven wheel is connected to the bending part, the driven wheel and the driving wheel are located on arcs with different radiuses and with the center of the platform part as the circle center, and the driven wheel and the driving wheel abut against the inner wall and the outer wall of the barrel respectively; the web profiling part comprises a first pressing wheel arranged at the bottom of the platform part; a height-adjustable ejector rod is arranged on the pressing assembly, a second pressing wheel is arranged on the ejector rod, and the first pressing wheel and the second pressing wheel abut against the upper surface and the lower surface of the web correspondingly. Due to the fact that the driving wheel, the driven wheel, the second pressing wheel and the first pressing wheel are attached to and pressed against the barrel and the web plate, the driving piece drives the driving wheel to rub against the outer wall of the barrel, the whole device moves to conduct back gouging according to the track of the joint of the barrel and the round reinforcing rib, and the back gouging effect is guaranteed.

Description

technical field [0001] The application relates to the technical field of mechanical tooling, and in particular, to a root cleaning device at the junction of a circular reinforcing rib and a cylinder. Background technique [0002] At present, root cleaning refers to the process of using appropriate tools to clean the root of the completed weld from the reverse side before welding on the reverse side for the full penetration weld formed by double-sided welding with high quality requirements. [0003] In some related technologies, manual grinding is mostly used for root cleaning, but its production efficiency is low, the groove after root cleaning is irregular, and the reverse weld bead is prone to unqualified conditions. Therefore, a root cleaning device has appeared. The device includes a mobile car and a root cleaning mechanism fixed on the mobile car obliquely; wherein, the root cleaning mechanism includes: a fixed plate, which is fixed on the mobile car obliquely through a...
