Description

Welding surface polishing device for large-scale component

Technical Field

The utility model relates to a welding surface grinding device for welding workpiece especially relates to a welding surface grinding device for large-scale component.

Background

The welding surface of the workpiece is rusted to a certain extent and has uneven surface before welding, and the workpiece needs to be polished before welding so as not to affect the welding effect. In addition, after the workpiece is welded, a weld crater appears on the surface of the workpiece, a grinding machine is used for processing the weld crater, the grinding of the weld crater can obtain better surface forming, and the grinding of the excess height of the weld seam can also reduce the concentrated stress at the weld seam.

The existing welding surface is polished by manually holding a polisher to polish the welding surface, so that time and labor are wasted, and the human arm operation area is limited, so that a person is required to be close to the surface of a welding seam to polish the welding surface. For the welding surface polishing of large-scale components, because the size of the components is large and the height is high, the position of the components needs to be repeatedly adjusted by people for polishing during manual polishing, and in the narrow part of the components, people are difficult to enter for polishing and other tools need to be used. The whole process of manual polishing of the welding surface of the large-sized component is complicated and inconvenient to operate.

Disclosure of Invention

An object of the utility model is to overcome prior art's defect, provide a welding surface grinding device for large-scale component, this device simple structure, with low costs, simple to operate, safe and reliable, can realize polishing automatically, can improve large-scale component welding surface's the efficiency of polishing.

The utility model provides a technical scheme that technical problem adopted does:

the utility model discloses a grinding device for welding surface of large-scale component, including the U-shaped track, a support includes cylindrical slide bar the bottom of cylindrical slide bar be fixed with a slider, the slider can slide around the U-shaped groove of U-shaped track, the motor cabinet of a motor passes through motor set screw and slider antetheca fixed connection, the left and right motor output shaft of motor set up along the horizontal direction and pass through friction pulley set screw respectively with the friction pulley fixed connection of left and right sides, the friction pulley of left and right sides support respectively on the top surface of the left and right sides lateral wall of U-shaped track and can roll around along the top surface of the left and right sides lateral wall of U-shaped track;

the one end suit of a horizontal pole just can follow cylindrical slide bar and reciprocate on cylindrical slide bar, the one end of a horizontal pole set screw with open the screw hole threaded connection of the one end of horizontal pole and tip top tightly set up on the lateral wall of cylindrical slide bar in order to link to each other with the horizontal pole is fixed with cylindrical slide bar in settlement position department, the other end of horizontal pole pass through polisher set screw and the lug on the polisher and link to each other in setting for the angle is fixed.

The utility model has the advantages that: the device has the advantages of simple structure, low cost, convenient installation, safety and reliability. In addition, when the grinding machine is used for grinding the welding surface, the grinding height, the grinding inclination angle and the grinding position can be adjusted, the operation is convenient, the adaptability is strong, the automatic grinding can be realized, and the grinding efficiency of the welding surface of the large member can be improved.
