[0002] In the production and manufacturing process of automobiles, welding equipment is required to perform welding operations between multiple parts of the automobile.

[0003] The existing welding equipment is generally a hanging spot welder. During the welding process, the operator actively turns on the power switch, water unit switch and gas unit switch of the hanging spot welder to start the welding operation. However, during the use of the hanging spot welder, the operator often misses the operation process of turning on the water unit switch and the gas unit switch after turning on the power switch because the equipment positions of the water unit switch and the gas unit switch are different from the setting positions of the power switch. In particular, when the water unit switch is not turned on, the electrode rod of the hanging spot welder cannot be cooled, resulting in overheating of the electrode rod, thereby affecting the quality of the welded joint and even causing heat damage to the cable.

[0004] Therefore, it is very easy for the existing suspension spot welding machine to omit the operation process of turning on the water unit switch during use. Summary of the invention

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Reference Figure 1 The present invention provides a switch linkage mechanism for a suspension spot welding machine, comprising: a lever structure 100 and a transmission structure 200. The lever structure 100 is arranged on the suspension spot welding machine, and when the operating end of the lever structure 100 moves in a direction close to or away from the suspension spot welding machine, the driving end of the lever structure 100 moves in a direction away from or close to the suspension spot welding machine. The transmission structure 200 is rotatably arranged on the driving end of the lever structure 100, and the driving end of the lever structure 100 can drive the transmission structure 200 to move. Two connecting ends are arranged on the transmission structure 200, and the transmission structure 200 drives the two connecting ends to move together. The two connecting ends are respectively connected to the water unit and the electric unit of the suspension spot welding machine, and the water unit and the electric unit of the suspension spot welding machine are driven to be turned on or off through the movement of the two connecting ends.

[0038] Specifically, the lever structure 100 is arranged on the suspension spot welding machine in the form of a lever, one end of the lever structure 100 is the operating end, and the other end of the lever structure 100 is the driving end. The part between the operating end and the driving end of the lever structure 100 is rotatably arranged, so that the operator can drive the driving end of the lever structure 100 to move away from the suspension spot welding machine by driving the operating end to move in the direction close to the suspension spot welding machine, or when the operator drives the operating end to move in the direction away from the suspension spot welding machine, the driving end of the lever structure 100 is driven to move in the direction close to the suspension spot welding machine. The transmission structure 200 is arranged on the driving end of the lever structure 100, and, with reference to Figure 2The transmission structure 200 is provided with two connection ends, and the two connection ends are respectively connected to the switch of the water unit and the switch of the electric unit of the suspension spot welding machine. When the driving end of the lever structure 100 moves in the direction away from the suspension spot welding machine, it can drive the two connection ends of the transmission structure 200 and the switch of the water unit and the switch of the electric unit respectively connected to the two connection ends to move together, so that the switch of the water unit and the switch of the electric unit can be turned on or off together at the same time, avoiding the situation that the operator forgets to turn on the switch of the water unit after turning on the switch of the electric unit, so that the electrode rod can be kept cooled when using the suspension spot welding machine, avoiding overheating of the electrode rod, ensuring the quality of the welding spot, and avoiding heating and damage of the cable.

[0039] In some specific embodiments of the present invention, referring to Figure 2 The lever structure 100 includes: a fixed frame 120 and a rotating frame 110. The fixed frame 120 is fixedly supported at the bottom of the suspension spot welding machine. The middle part of the rotating frame 110 is rotatably connected to the fixed frame 120, and the driving end of the lever structure 100 is formed by one end of the rotating frame 110, and the operating end of the lever structure 100 is formed by the other end of the rotating frame 110.

[0040] Specifically, the fixed frame 120 is arranged at the bottom of the suspension spot welder, and the top of the fixed frame 120 is fixedly connected to the bottom of the suspension spot welder, so that the suspension spot welder can be supported by the fixed frame 120, and the suspension spot welder can be fixed by the fixed frame 120, which is convenient for installation and use. The rotating frame 110 is arranged below the bottom of the suspension spot welder, and the two sides of the middle of the rotating frame 110 are rotatably connected to the two ends of the fixed frame 120, so that the rotating frame 110 can rotate with the connection between the rotating frame 110 and the fixed frame 120 as the axis, and the lever structure 100 is realized by the cooperation of the rotating frame 110 and the fixed frame 120. Among them, one end of the rotating frame 110 is the operating end, and the other end of the rotating frame 110 is the driving end. When the rotating frame 110 rotates with the connection between the rotating frame 110 and the fixed frame 120 as the axis, the movement directions between the operating end and the driving end of the rotating frame 110 are opposite. When the operating end of the rotating frame 110 moves toward the direction close to the hanging spot welder, the driving end of the rotating frame 110 moves away from the hanging spot welder. When the operating end of the rotating frame 110 moves toward the direction away from the hanging spot welder, the driving end of the rotating frame 110 moves toward the direction close to the hanging spot welder. The structure is simple, the installation is convenient, and it is easy to implement.

[0041] Furthermore, there are two fixing frames 120, which are symmetrically arranged at the bottom of the hanging spot welding machine, and the tops of the two fixing frames 120 are fixedly connected to the bottom of the hanging spot welding machine, so that the hanging spot welding machine can be supported by the two fixing frames 120, and the hanging spot welding machine can be fixed by the two fixing frames 120, which is convenient for installation and use, and improves the fixing stability of the hanging spot welding machine.

[0042] In some specific embodiments of the present invention, referring to Figure 2 , the bottom of the fixed frame 120 is connected with a connecting frame 130. The fixed frame 120 is rotatably connected with the middle two sides of the rotating frame 110 through the two ends of the connecting frame 130. Specifically, the bottom of the fixed frame 120 is fixedly connected with the connecting frame 130, and the two ends of the connecting frame 130 are extended in the direction of the two sides close to the middle of the rotating frame 110 and are rotatably connected with the rotating frame 110, so that the fixed frame 120 is rotatably connected with the rotating frame 110 through the connecting frame 130. Under the extension of the connecting frame 130, the length of the fixed frame 120 can be limited, thereby avoiding the difficulty of installing the fixed frame 120 on the bottom of the suspension spot welding machine due to the excessive length of the fixed frame 120. At the same time, under the extension of the connecting frame 130, the width of the rotating frame 110 can also be limited, so that the two sides of the rotating frame 110 can be aligned with the switch of the water unit and the switch of the electric unit of the suspension spot welding machine, thereby avoiding the difficulty of setting the transmission structure 200 due to the short width of the rotating frame 110. The structure is simple, easy to install, and easy to implement.

[0043] In some specific embodiments of the present invention, referring to Figure 1 , the bottoms of both ends of the connection frame 130 are bent and extended toward the direction close to the operating end of the rotating frame 110 and connected to the rotating frame 110. Specifically, the bottoms of both ends of the connection frame 130 are L-shaped structures, so that the bottoms of both ends of the connection frame 130 can be bent and extended toward the direction close to the operating end of the rotating frame 110 and be rotatably connected to the position close to the operating end of the rotating frame 110. In this way, the force arm ratio between the operating end and the driving end of the rotating frame 110 can be changed, so that the distance between the connection of the rotating frame 110 and the connection frame 130 and the operating end is smaller than the distance between the connection of the rotating frame 110 and the connection frame 130 and the driving end, which is convenient for operators to control.

[0044] In some specific embodiments of the present invention, referring to Figure 1, the rotating frame 110 is a U-shaped structure, and the open end of the rotating frame 110 of the U-shaped structure is the driving end of the rotating frame 110. Specifically, one end of the rotating frame 110 of the U-shaped structure is an open form, and the other end is a closed form. Thus, the driving end of the rotating frame 110 is formed by the open end of the rotating frame 110, and the transmission structure 200 can be set by the frames on both sides of the open end of the rotating frame 110, while ensuring the alignment and connection with the switch of the water unit and the switch of the electric unit of the hanging spot welder, the driving end of the rotating frame 110 is prevented from being stuck with the fixed frame 120 or the hanging spot welder. The operating end of the rotating frame 110 is formed by the closed end of the rotating frame 110, and the handle is formed by the frame of the closed end of the rotating frame 110, which is convenient for the operator to hold and improves the convenience of driving the rotating frame 110 to rotate.

[0045] In some specific embodiments of the present invention, referring to Figure 2 The transmission structure 200 includes: a first transmission rod 210 and a second transmission rod 220. One end of the first transmission rod 210 is rotationally connected to the driving end of the rotating frame 110, and the other end of the first transmission rod 210 is rotationally connected to the water inlet switch 212 and the water return switch 213 of the water unit of the suspension spot welder. One end of the second transmission rod 220 is rotationally connected to the driving end of the rotating frame 110, and the other end of the second transmission rod 220 is connected to the power switch of the electric unit of the suspension spot welder. The two connection ends of the transmission structure 200 are formed by the first transmission rod 210 and the second transmission rod 220 away from the rotating frame 110.

[0046] Specifically, the bottom end of the first transmission rod 210 is rotatably connected to one of the frame frames of the driving end of the rotating frame 110, and the top end of the first transmission rod 210 is one of the connection ends of the transmission structure 200. The top end of the first transmission rod 210 is rotatably connected to the water inlet switch 212 and the water return switch 213 of the water unit of the hanging spot welder, so that by driving the first transmission rod 210 to move in a direction close to or away from the hanging spot welder, the water inlet switch 212 and the water return switch 213 of the water unit of the hanging spot welder rotatably connected to the top end of the first transmission rod 210 can be driven to move together, thereby realizing the simultaneous opening or closing of the water inlet switch 212 and the water return switch 213 of the water unit of the hanging spot welder. Figure 3The bottom end of the second transmission rod 220 is rotatably connected to another frame of the driving end of the rotating frame 110, and the top end of the second transmission rod 220 is another connection end of the transmission structure 200. The top end of the second transmission rod 220 is connected to the power switch of the electric unit of the suspension spot welder, so that by driving the second transmission rod 220 to move in a direction close to or away from the suspension spot welder, the power switch of the electric unit of the suspension spot welder connected to the top end of the second transmission rod 220 can be driven to move together, thereby realizing the opening or closing of the power switch of the electric unit of the suspension spot welder. By moving the driving end of the rotating frame 110, the first transmission rod 210 and the second transmission rod 220 can be driven to move in a direction close to or away from the suspension spot welder at the same time, so that the water inlet switch 212 and the water return switch 213 of the water unit and the power switch of the electric unit can be turned on or off. It can avoid the situation that the operator forgets to turn on the water unit switch after turning on the electric unit switch, so that the electrode rod can be kept cool when using the hanging spot welding machine, avoiding overheating of the electrode rod, ensuring the quality of the welding spot, and avoiding heating damage to the cable. In addition, the structure is simple, easy to install, and easy to implement.

[0047] In some specific embodiments of the present invention, referring to Figure 2 A transmission arm 211 is fixedly provided at one end of the first transmission rod 210 away from the rotating frame 110. The two ends of the transmission arm 211 extend toward the direction of the water inlet switch 212 and the water return switch 213 of the water unit close to the hanging spot welder and are rotatably connected with the water inlet switch 212 and the water return switch 213 of the water unit of the hanging spot welder. Specifically, the transmission arm 211 is a T-shaped structure, the bottom end of the transmission arm 211 is fixedly connected with the top end of the first transmission rod 210, and the two ends of the top of the transmission arm 211 extend toward the direction of the water inlet switch 212 and the water return switch 213 of the water unit close to the hanging spot welder until they are rotatably connected with the water inlet switch 212 and the water return switch 213 of the water unit of the hanging spot welder. When the first transmission rod 210 moves in a direction close to or away from the suspension spot welder, it can drive the transmission arm 211 fixedly connected to the first transmission rod 210 to move, and then drive the water inlet switch 212 and the water return switch 213 of the water unit of the suspension spot welder respectively connected to the top ends of the transmission arm 211 to move together, so as to realize the simultaneous opening or closing of the water inlet switch 212 and the water return switch 213 of the water unit of the suspension spot welder. The structure is simple, easy to install, and easy to implement.

[0048] In some specific embodiments of the present invention, referring to Figure 2, a first sliding groove is provided on the driving end of the rotating frame 110. One end of the first transmission rod 210 close to the rotating frame 110 is rotatably arranged in the first sliding groove. A second sliding groove and a third sliding groove are respectively provided on the water inlet switch 212 and the water return switch 213 of the water unit of the suspension spot welding machine. The two ends of the transmission arm 211 are rotatably arranged in the second sliding groove and the third sliding groove. Specifically, a first sliding groove is provided on the frame of the driving end of the rotating frame 110 that is rotatably connected to the first transmission rod 210 along the setting direction of the frame, and the bottom end of the first transmission rod 210 is a bending structure, so that the bending position of the bottom end of the first transmission rod 210 can be directly arranged in the first sliding groove. When the first transmission rod 210 is driven to move, the bottom end of the first transmission rod 210 can rotate relative to the first sliding groove, and the bottom end of the first transmission rod 210 can also slide in the first sliding groove along the opening direction of the first sliding groove, thereby avoiding the movement direction deviation of the bottom of the first transmission rod 210. At the same time, a second sliding groove is provided on the water inlet switch 212 along the setting direction of the water inlet switch 212, and a third sliding groove is provided on the water return switch 213 along the setting direction of the water return switch 213. Both ends of the top of the transmission arm 211 are bent structures, and the bent position of the top of the transmission arm 211 close to the water inlet switch 212 is directly penetrated through the second sliding groove, and the bent position of the top of the transmission arm 211 close to the water return switch 213 is directly penetrated through the third sliding groove. When the first transmission rod 210 and the transmission arm 211 are driven to move, the two ends of the top of the transmission arm 211 can rotate relative to the second sliding groove and the third sliding groove, and can also slide in the second sliding groove and the third sliding groove along the opening direction of the second sliding groove and the third sliding groove, respectively, so as to avoid the top of the first transmission rod 210 and the movement direction of the transmission arm 211 from deviating.

[0049] In some specific embodiments of the present invention, referring to Figure 1 The second transmission rod 220 has an embedding groove at one end away from the rotating frame 110, and the embedding groove can be used for the power switch of the electric unit of the hanging spot welding machine to be embedded and connected. Specifically, the top of the second transmission rod 220 has an embedding groove, and the shape and size of the embedding groove are adapted to the power switch of the electric unit. After the installation is completed, the power switch of the electric unit can be embedded in the embedding groove, so that the movement of the second transmission rod 220 can drive the power switch of the electric unit to move together to achieve opening and closing.

[0050] In some specific embodiments of the present invention, referring to Figure 2, a limit seat 230 is slidably sleeved on the outer periphery of the first transmission rod 210, and the limit seat 230 is detachably arranged on the suspension spot welding machine. Specifically, the limit seat 230 is detachably arranged on the suspension spot welding machine, and the limit seat 230 is arranged adjacent to the frame of the driving end of the rotating frame 110 and is rotatably connected to the first transmission rod 210, and a sliding hole is opened on the side of the limit groove facing the first transmission rod 210, and the first transmission rod 210 is penetrated by the sliding hole, so that the limit seat 230 can be slidably sleeved on the outer periphery of the first transmission rod 210 through the sliding hole. The sliding hole of the limit seat 230 can limit the movement of the first transmission rod 210 along the axial direction of the sliding hole, thereby avoiding the movement deviation of the first transmission rod 210.
