[0004] However, the above device still has shortcomings:

[0005] During spot welding operations, the temperature of the gun tip is high, and multi-point welding requires the gun tip to work for a long time. The gun tip will be in a high temperature state for a long time. If it cannot be effectively temperature-controlled, the continuous high temperature may reduce the service life of the gun tip.

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a multi-station spot welding machine that solves the problem that the temperature of the gun tip is high during spot welding operations. In addition, multi-station welding requires the gun tip to work for a long time, which causes the gun tip to be in a high temperature state for a long time. If the temperature is not effectively controlled, the continuous high temperature may reduce the service life of the gun tip.

[0007] To achieve the above-mentioned object, the present invention proposes a multi-station spot welding machine, comprising a workbench, an outer disk is provided above the workbench, a cooling liquid tank is fixedly connected to the top of the outer disk, a liquid outlet is provided on the side wall of the cooling liquid tank, a through slot is provided on the end of the cooling liquid tank and the outer disk, a driving disk is rotatably connected to the bottom of the cooling liquid tank, and a control component is provided inside the outer disk, wherein:

A spring is provided at one end of the driving triangular block away from the liquid outlet, and the spring is arranged in the through groove. The two ends of the spring are respectively fixedly connected to the outer disk and the driving triangular block, and a plurality of driving columns are fixedly connected to the top of the driving disc, and the driving columns and the inclined surface of the driving triangular block conflict with each other. The outer side wall of the cooling liquid tank is fixedly connected to a nozzle, and the nozzle is communicated with the liquid outlet.

[0009] Preferably, a plurality of pillars are fixedly connected to the bottom of the workbench.

[0010] Preferably, a pair of track plates are fixedly connected to the top of the workbench, a pair of inner side walls of the track plates are provided with a conveyor belt, and a discharge bucket is provided on the side wall of the workbench, and the discharge bucket and the conveyor belt are arranged on the same horizontal plane.

[0011] Preferably, a control system is fixedly connected to the top of the workbench.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This can be achieved through the setting of the control component. When the electric welding operation is performed, the driving disc rotates, and the driving column will contact the inclined surface of the driving triangle block, thereby driving the driving triangle block to move away from the liquid outlet. Driven by the driving triangle block, the protrusion will separate from the liquid outlet, and the liquid in the cooling liquid tank can be discharged through the liquid outlet, thereby achieving the cooling effect.

[0016] The advantage of this design is that the cooling operation can be achieved by driving the rotation of the disc, so that the control component can perform cooling operations on each gun head, ensuring that the gun head can be cooled in time after completing the welding operation. Through automatic control, the cooling efficiency can be greatly improved, and manual intervention can be reduced. Each gun head can receive the same cooling treatment, which greatly reduces the loss of the gun head and increases the service life of the gun head. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-4 As shown, a multi-station spot welding machine includes a workbench 1, and a plurality of pillars 2 are fixedly connected to the bottom of the workbench 1.

[0024] A pair of track plates 3 are fixedly connected to the top of the workbench 1, and a conveyor belt 31 is provided on the inner wall of the pair of track plates 3. Multiple welding stations can be placed on the conveyor belt 31. The multiple welding stations are transmitted in sequence under the action of the conveyor belt 31. This uninterrupted welding method can improve the efficiency of welding. A discharge bucket 32 is provided on the side wall of the workbench 1, and the discharge bucket 32 and the conveyor belt 31 are arranged on the same horizontal plane.

[0025] A control system 5 is fixedly connected to the top of the workbench 1 , and the control system 5 can control the transmission speed of the transmission belt 31 and the rotation speed of the driving disc 61 so that the transmission speed of the transmission belt 31 can match the rotation speed of the driving disc 61 .

[0026] The top of the workbench 1 is fixedly connected to an electric outer rod 4, the top of the electric outer rod 4 is slidably connected to an electric inner rod 41, the top of the electric inner rod 41 is fixedly connected to a connecting column 42, the outer side of the connecting column 42 is fixedly connected to a straight plate 43, the bottom of the end of the straight plate 43 away from the electric inner rod 41 is fixedly connected to a fixed column 44, an outer disk 45 is provided above the workbench 1, and the outer disk 45 is fixedly connected to the bottom of the fixed column 44.

[0027] The top of the outer disk 45 is fixedly connected to a cooling liquid tank 6, a liquid outlet 601 is provided on the side wall of the cooling liquid tank 6, through grooves 602 are provided at the ends of the cooling liquid tank 6 and the outer disk 45, the bottom of the cooling liquid tank 6 is rotatably connected to a driving disk 61, and a control component 7 is provided inside the outer disk 45.

[0028] The control assembly 7 includes a slider 71, which is slidably connected to the inside of the cooling liquid tank 6. The end of the slider 71 is fixedly connected to a protrusion 701, which is arranged in the liquid outlet 601. The bottom of the slider 71 is fixedly connected to a driving triangular block 72, which is arranged in a triangle shape and is slidably connected to the through groove 602. The end of the driving triangular block 72 away from the liquid outlet 601 is provided with a spring 73, which is arranged in the through groove 602. The two ends of the spring 73 are respectively fixedly connected to the outer disk 45. The top of the driving disc 61 is fixedly connected to the driving triangle block 72 and a plurality of driving columns 74. The driving columns 74 and the inclined surfaces of the driving triangle block 72 conflict with each other. When the electric welding operation is performed, the driving disc 61 rotates, and the driving columns 74 come into contact with the inclined surfaces of the driving triangle block 72, thereby driving the driving triangle block 72 to move away from the liquid outlet 601. Driven by the driving triangle block 72, the protrusion 701 is separated from the liquid outlet 601, and the liquid in the cooling liquid tank 6 can be discharged through the liquid outlet 601, thereby achieving a cooling effect.

[0029] The cooling operation can be achieved by driving the rotation of the disc 61, so that the control component 7 can perform cooling operation on each gun head 62, ensuring that the gun head 62 can be cooled in time after completing the welding operation. Through automatic control, the cooling efficiency can be greatly improved, and manual intervention can be reduced.

By adjusting the density of the arrangement of the gun heads 62, the number of gun heads 62 set above the conveyor belt 31 can be adjusted. According to the number of gun heads 62 set above the conveyor belt 31, the corresponding welding station is selected to achieve multi-station welding. The position where the gun head 62 is set corresponds one-to-one to the position where the driving column 74 is set.

[0032] Working principle: During operation, the welding stations are placed on the conveyor belt 31 at certain intervals, and then the conveyor belt 31 and the driving disc 61 are driven to start by controlling the control system 5. The driving disc 61 starts to rotate. When the driving disc 61 rotates, the driving column 74 will contact the inclined surface of the driving triangle block 72, thereby driving the driving triangle block 72 to move away from the liquid outlet 601. Driven by the driving triangle block 72, the protrusion 701 is separated from the liquid outlet 601, and the liquid in the cooling liquid tank 6 can be discharged through the liquid outlet 601, thereby achieving a cooling effect.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
