Description

Technical Field

[0001] The utility model relates to the field of welding equipment, in particular to an auxiliary device for replacing a welding head. Background Technique

[0002] As shown in a typical welding equipment Figure 3 The working process is as follows: First, start the power supply to make the welding head move downward and press two welding objects, then press the welding switch to generate an instant high-intensity current at the joint of the two, causing local melting and welding them together. However, during precision welding, for example, when one of the welding objects is a metal wire with a diameter of ￠0.03mm, it is necessary to precisely control the height of the welding head relative to the welding object so that the welding head can firmly press the two welding objects after pressing down. Otherwise, the welding may be insecure, affecting the welding quality. When installing or replacing the welding head, it is very difficult to adjust the height of the welding head in place at one time, and it is easy to adjust too high or too low. It takes a long time to continuously adjust the height of the welding head and try welding to precisely determine the height of the welding head, which will waste a lot of materials. Chinese Utility Model CN211915903U discloses a valve body welding robot with adjustable welding torch height. By rotating the control rod, the control rod drives the rotating rod to rotate inside the first bolt hole, so that the first support frame and the second support frame rise, thus realizing the function of height control. However, the above design includes multiple rotating connection points and adjustment mechanisms, increasing the structural complexity and input cost. Wear and looseness caused by long-term use will also reduce the accuracy. Therefore, it is necessary to design an auxiliary device for replacing the welding head, which can quickly and precisely adjust the height of the welding head. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the above-mentioned defects existing in the prior art and provide an auxiliary device for replacing a welding head, which can quickly and precisely adjust the height of the welding head.

[0004] The purpose of the utility model can be achieved by the following technical solutions:

[0005] The utility model provides an auxiliary device for replacing a welding head, including a support base and a rotating platform. A through hole is provided on the support base, and an adjusting rod passing through the through hole is provided at the bottom of the rotating platform. Fine-pitched threads that cooperate with each other are evenly provided on the outer surface of the adjusting rod and the inner wall of the through hole, so that the support base and the rotating platform are connected with variable distance. The edge of the rotating platform extends downward, and a limiting component is provided at the end for locking the support base and the rotating platform.

[0006] Further, the limiting component includes a positioning nut and a screw hole provided on the side wall of the rotating platform.

[0007] Furthermore, the length of the positioning nut is greater than the depth of the threaded hole.
