Coaxial welding positioning device

Abstract

The invention discloses a coaxial welding positioning device. The coaxial welding positioning device comprises a body, a plurality of welding holes penetrate through the middle of the body in the radial direction of the body, the two ends of the body are a main hole end and an auxiliary hole end respectively, a main hole adapting to a main welding part penetrates through the main hole end in the axial direction of the body, and an auxiliary hole adapting to an auxiliary welding part penetrates through the auxiliary hole end in the axial direction of the body. A set bolt hole penetrates through the sidewall of the main hole end in the radial direction of the body, a set bolt matched with the main welding part is assembled in the set bolt hole, a lock screw hole penetrates through the sidewall of the auxiliary hole end in the radial direction of the body, and a lock screw matched with the auxiliary welding part is assembled in the lock screw hole. The coaxial welding positioning device can effectively guarantee the coaxiality of a shaft in an online welding process and improve structural reliability of the welded shaft.

Description

technical field [0001] The invention relates to the technical field of machining welding equipment, in particular to a coaxial welding positioning device. Background technique [0002] In the field of machining of the current industrial system, shaft components are widely used as an important part of various machinery. Among various rotary parts, the application of stepped shafts is particularly common. [0003] At present, in the actual operation process, if the shaft structure is broken or worn and other structural damage occurs, it is generally necessary to stop the machine and replace the corresponding damaged parts. The process needs to be shut down, and the replacement process is cumbersome, time-consuming and labor-intensive; another treatment method is to adopt online repair, that is, the failure part of the damaged part is broken and then welded with the corresponding replacement part, but this operation method cannot guarantee the welding process. If the coaxiali...

[0003] At present, in the actual operation process, if the shaft structure is broken or worn and other structural damage occurs, it is generally necessary to stop the machine and replace the corresponding damaged parts. The process needs to be shut down, and the replacement process is cumbersome, time-consuming and labor-intensive; another treatment method is to adopt online repair, that is, the failure part of the damaged part is broken and then welded with the corresponding replacement part, but this operation method cannot guarantee the welding process. If the coaxiality is too high, the normal working stability and reliability of the shafting system cannot be guaranteed, and the repair effect is poor, which will cause safety hazards to the normal operation of the equipment.
