Description

Technical Field

[0001] The utility model relates to the field of welding repair devices, in particular to a fast-positioning roller welding repair device. Background Art

[0002] Roller, also known as roller, is a general term for cylindrical parts that can roll on the machine. This word has two meanings: the first meaning is roller, but because this roller is a whole without other components, it is shaped like an axis, and the rotating shaft is itself. Chinese people like to read the two words together, so it is called roller. For example, most rolling rollers are like this; the second meaning is the axis used for rollers. This kind of roller is a combined roller, which is composed of an axis, bearing, roller sleeve, and sealing ring. The following parts are all sleeved on the axis, such as the conveyor belt roller. Usually, the roller is easy to wear, and replacing the roller will increase the manufacturing and processing costs. Therefore, reasonable repair is very important, and the repair needs to be aligned with the wear position, and the processing adjustment device becomes a very important problem that needs to be solved.

[0003] After searching, the publication number is: CN108857202A. An adjustable roller welding repair device comprises a bracket and a lathe arranged at the lower end of the bracket, the bracket is provided with a rotating device for making the welding gun rotate in a circular shape, the rotating device is provided with a lifting device for making the welding gun rise and fall, the lifting device is provided with a moving device for making the welding gun move in the X direction, the lathe is provided with a clamping device for clamping the roller and making the roller rotate for facilitating welding repair, the lower end of the clamping device is provided with a slag loading plate for placing slag and other debris generated during welding, the position of the welding gun is adjusted by using a rotating motor and a moving motor, and it can be flexibly adjusted according to the position where the roller needs to be welded, and it has wide applicability; the roller is fixed by using a cylinder clamp and a three-jaw chuck to prevent the roller from shaking during welding and affecting the welding repair effect.

[0004] However, the device has the following disadvantages: although the above-mentioned device uses a rotating motor and a moving motor to adjust the position of the welding gun, it can be flexibly adjusted according to the position of the roller shaft that needs to be welded, and has a wide applicability; the cylinder clamp and the three-jaw chuck are used to fix the roller shaft to prevent the roller shaft from shaking during the welding process and affecting the welding repair effect, but in actual use, the handwheel of the device is not equipped with a limit device, and the position of the handwheel has no clear locking point. It is difficult for the operator to quickly and accurately position the device, which may lead to prolonged operation time and affect the efficiency of the repair work.

[0005] Therefore, in order to solve the above problems, a roller shaft welding repair device with rapid positioning is proposed. Utility Model Content
