A power supply connection device for an electric welding machine

Abstract

The invention discloses a welding device. The welding device comprises a base, a cylinder, a push portion and a plug head portion, the cylinder is fixedly arranged above the base, the push portion is fixedly connected at the top of the cylinder and extends leftwards, a plugging groove is formed in the left end face of the cylinder, vertically symmetrical plugging springs are arranged on the inner right wall of the plugging groove, a sensor is arranged at the position, between the two plugging springs, of the inner right wall of the plugging groove, a mounting groove is formed in the top end face of the push portion, a sliding groove is formed in the left bottom end face of the push portion, a sliding cavity is formed in the push portion above the right side of the sliding groove, a force transfer cavity is formed in the position, on the right sides of the sliding cavity and the sliding groove, of the push portion, a first toothed wheel is arranged below the inner portion of the force transfer cavity, a second toothed wheel is connected to the top of the first toothed wheel in a mesh manner, a first rotating rod extending leftwards and rightwards is fixedly arranged on the first toothed wheel, and a second rotating rod extending leftwards and rightwards is fixedly arranged on the second toothed wheel. The welding device is simple in structure, convenient to operate, high in safety and capable of achieving plugging automatically and has a prompt function.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a power supply connection device for an electric welding machine. Background technique [0002] At present, with the application of electric welding machines more and more widely, people have higher and higher safety requirements for the use of electric welding machines. However, electric welding machines rely on power supply connections to work, so whether the power supply connection is Safety is the prerequisite to ensure the normal use of electric welding machines. The existing electric welding machines are generally plugged and unplugged manually by personnel during the power supply connection process. However, due to the high voltage required by the electric welding machine, arcs are easily generated during the plugging process It is easy to cause electric shock to the user, which has a certain potential danger to the user, which will cause safety accidents and cause casual...

[0002] At present, with the application of electric welding machines more and more widely, people have higher and higher safety requirements for the use of electric welding machines. However, electric welding machines rely on power supply connections to work, so whether the power supply connection is Safety is the prerequisite to ensure the normal use of electric welding machines. The existing electric welding machines are generally plugged and unplugged manually by personnel during the power supply connection process. However, due to the high voltage required by the electric welding machine, arcs are easily generated during the plugging process It is easy to cause electric shock to the user, which has a certain potential danger to the user, which will cause safety accidents and cause casualties, and the force of the personnel on the plug is unstable, which can easily lead to damage to the power supply part, shortening the service life and consuming time and effort. In addition, the existing electric welding machine does not have a prompt function during the plug-in power supply process, so that the operator cannot understand the power supply status of the electric welding machine at the first time, which has great disadvantages and brings inconvenience to the user.
