Description

Technical Field

[0001] The present invention relates to the field of robots, and more particularly to a device for detecting the center alignment of the contact tip and the gun nozzle of an arc welding robot. Background Art

[0002] After being used for a period of time, the contact tip and the gun nozzle of the existing arc welding robot will be deformed, and it is impossible to check whether they are deformed with the naked eye, resulting in the protective gas being unable to effectively protect the weld seam, causing quality defects such as excessive weld seam pores, which will directly affect the weld quality of the parts. Summary of the Invention

[0003] Technical Problem to be Solved

[0004] The technical problem to be solved by this patent is that the contact tip and the gun nozzle of the welding torch will be deformed after being used for a period of time. This patent proposes a device for quickly detecting the center alignment of the contact tip and the gun nozzle of an arc welding robot.

[0005] Technical Solution

[0006] To solve the above problems, the present invention proposes the following technical solutions:

[0007] A device for detecting the center alignment of the contact tip and the gun nozzle of an arc welding robot includes an annular guide rail, rollers, a sliding seat and a detection device; the detection device includes an induction contact, a spring and an amplitude induction sensor. The detection device is installed inside the sliding seat. The sliding seat contacts the annular guide rail through the rollers, and the rollers will drive the sliding seat to move in a circular motion along the annular guide rail. If the contact tip or the gun nozzle is deformed, the induction contact will move up and down under the action of force. At this time, the amplitude induction sensor will sense the amplitude value of the change of the contact and transmit the result to the host computer and display it on the display screen, so that the operator can clearly see whether the centers of the contact tip and the gun nozzle of the arc welding robot are aligned.

[0008] In the device for detecting the center alignment of the contact tip and the gun nozzle of an arc welding robot, the upper part of the induction contact is hemispherical, and the induction contact will contact the outer side of the contact tip and the inner side of the gun nozzle during the detection process.

[0009] In the device for detecting the center alignment of the contact tip and the gun nozzle of an arc welding robot, the spring is used to connect the induction contact and the amplitude induction sensor.

[0010] In the device for detecting the center alignment of the contact tip and the gun nozzle of an arc welding robot, the detection equipment further includes a host computer connected to the amplitude induction sensor and a display connected to the host computer.

[0011] This patent solves the problem that the welding torch contact tip and the welding torch nozzle of an arc welding robot will deform after being used for a period of time, and the use of traditional measurement methods is cumbersome and the measurement results are inaccurate. A device for quickly detecting the centering of the center points of the contact tip and the welding torch nozzle of an arc welding robot proposed in this patent can quickly and accurately measure the deformation of the contact tip and the welding torch nozzle.

[0017] As Figure 2 shown: When the roller 2 drives the slide seat 3 to make a circular motion along the ring-shaped guide rail 1, if the contact tip 6 or the welding torch nozzle 5 deforms, the inductive contact 4-1 will move up and down under the action of force.
