Description

Technical Field

[0001] This utility model relates to the field of resistance welding equipment technology, specifically a resistance welding head. Background Technology

[0002] Existing resistance welding heads, used in precision welding operations, typically employ a low-pressure, non-adjustable head structure. However, due to the head's own weight, the welding pressure exceeds the preset limit, resulting in lower welding accuracy and reduced yield. Therefore, there is a need for a resistance welding head with adjustable welding pressure to address these issues. Utility Model Content

[0003] The purpose of this application is to provide a technical solution to address the problems mentioned in the background section.

[0004] To achieve the above objectives, this application provides the following technical solution:

The base includes a limiting part and a slide seat part.

[0006] One end of the gravity-balancing elastic element is connected to the slide rail, and the other end is connected to the limiting part;

[0007] One end of the slide rail limiting block is connected to the first detection sensor, and the other end is disposed inside the limiting part.

[0008] One end of the second elastic pressure regulating member is connected to the first pressure regulating member, and the other end is elastically connected to the other end of the first detection sensor through the top of the limiting part;

[0009] One end of the second detection sensor is connected to the other end of the slide rail limiting block through the bottom of the limiting part, the other end of the second detection sensor is connected to one end of the slide rail, and the other end of the slide rail is connected to the welding head mounting part. The slide rail is slidably connected to the slide base part.

[0010] Preferably, the first pressure regulating component is an adjusting screw.

[0011] Preferably, the second elastic pressure adjusting element is a pressure adjusting spring.

[0012] Preferably, one section of the pressure adjusting spring is sleeved on one section of the adjusting screw.

[0013] Preferably, the first detection sensor is a pressure detection sensor.

[0017] Preferably, the gravity-balancing elastic element is a spring or a tension spring.

[0018] In summary, the technical effects and advantages of this utility model are as follows:

[0019] Before resistance welding, the pressure to be adjusted can be applied or released to the second elastic pressure adjusting component through the first pressure adjusting component. The applied or released pressure is then transmitted to the slide rail and finally to the welding head mounting part through the gravity balancing elastic component to achieve the purpose of pressure adjustment. In this process, the gravity balancing elastic component can balance part or all of the weight of the whole machine. The second elastic pressure adjusting component can adjust the welding pressure of the welding head mounted in the welding head mounting part to be less than the weight of the whole machine. The first detection sensor can be used to detect the change in the pressure (elastic modulus) of the pressure applied or released by the first pressure adjusting component to the second elastic pressure adjusting component, while the second detection sensor can be used to detect the welding pressure of the welding head mounted in the welding head mounting part. This achieves precise and controllable adjustment of the welding head welding gravity balance, effectively improving welding accuracy and welding yield. Attached Figure Description

[0031] The second elastic pressure regulating member 2 is connected to the first pressure regulating member 1 at one end, and the other end is elastically connected to the other end of the first detection sensor 3 through the top of the limiting part 61;

[0032] One end of the second detection sensor 4 is connected to the other end of the slide rail limiting block 7 through the bottom of the limiting part 61, and the other end of the second detection sensor 4 is connected to one end of the slide rail 5, and the other end of the slide rail 5 is connected to the welding head mounting part 8. The slide rail 5 is slidably connected to the slide base part 62.

[0033] Working principle: Before resistance welding, the pressure to be adjusted can be applied or released to the second elastic pressure adjusting component 2 through the first pressure adjusting component 1. The applied or released pressure is then transmitted to the slide rail 5 and finally to the welding head mounting part 8 through the gravity balancing elastic component 9 to achieve the purpose of pressure adjustment. During this process, the gravity balancing elastic component 9 can balance part or all of the weight of the whole machine. The second elastic pressure adjusting component 2 can adjust the welding pressure of the welding head installed in the welding head mounting part 8 to be less than the weight of the whole machine. The first detection sensor 3 can be used to detect the change in the pressure (elastic modulus) of the pressure applied or released by the first pressure adjusting component 1 to the second elastic pressure adjusting component 2, while the second detection sensor 4 can be used to detect the welding pressure of the welding head installed in the welding head mounting part 8, thereby achieving precise and controllable adjustment of the welding head welding gravity balance and effectively improving the welding accuracy.

[0034] Preferably, the first pressure regulating component 1 is an adjusting screw, and the second elastic pressure regulating component 2 is a pressure regulating spring, with one end of the pressure regulating spring sleeved on one end of the adjusting screw; when the adjusting screw applies or releases the pressure to be adjusted to the pressure regulating spring, the pressure can be adjusted or released simply by turning it. The threaded adjustment structure of the adjusting screw can effectively reduce manufacturing costs, and secondly, it facilitates the user's control over the adjustment.

[0035] Preferably, the first detection sensor 3 is a pressure detection sensor, used to detect the change in the pressure (elastic modulus) applied or released by the first pressure regulating member to the second elastic pressure regulating member.

[0036] Preferably, the second detection sensor 4 is a pressure detection sensor used to detect the welding pressure of the welding head installed in the welding head mounting part.

[0037] In one embodiment, the gravity balancing elastic element 9 is elastically connected to the slide rail 5 at one end and fixedly connected to the limiting part 61 at the other end. This achieves precise and controllable adjustment of the gravity balance of the welding head, effectively improving welding accuracy while also saving manufacturing costs.

[0038] One implementation method also includes a fixing block 10 and a gravity balance elastic element adjustment screw 11. One end of the gravity balance elastic element 9 is elastically connected to the slide rail 5, and the other end is connected to the fixing block 10 and screwed onto the limiting part 61 by the gravity balance elastic element adjustment screw 11. This achieves precise and controllable adjustment of the welding head's gravity balance, effectively improving welding accuracy. At the same time, the gravity balance elastic element 9 can be adjusted by the gravity balance elastic element adjustment screw 11, thereby realizing a triple adjustment mechanism. Compared with the above embodiments, the welding accuracy is more precise.
