Description

Technical Field

[0001] The present invention relates to the technical field of automobile chassis processing, and in particular to an automatic welding device for parts of a new energy automobile chassis and a use method thereof. Background Art

[0002] As the foundation of the automobile industry, automobile parts are necessary factors to support the sustainable and healthy development of the automobile industry. The bottom of the car has a chassis. When the automobile chassis is processed, the parts need to be fixed on the automobile chassis, and then the parts are welded to the automobile chassis. During the processing of automobile parts, the parts are generally placed on the welding table, and then the parts are limited by two sets of clamps for welding operations.

[0003] When welding on one side, the existing automobile chassis parts welding device usually lacks support on the other side. It only relies on the clamp for clamping, which may cause the welding head to push slightly during the welding process, resulting in a decrease in welding accuracy over time. At present, most of the welding equipment on the market has supports, which is difficult to apply to automobile chassis parts of different models. When using, the corresponding support components need to be replaced, which has poor applicability and reduces welding efficiency.

[0004] At the same time, the current automated fixtures usually have a slight decrease in displacement accuracy after being used for too long due to long-term clamping of the workpiece, resulting in slight changes in the position of the automobile chassis parts after fixation, causing slight displacement of the welding points, and ultimately resulting in poor welding stability, causing defects in the welding parts of the product.

[0037] like Figures 1 to 8 As shown, an embodiment of the present invention provides an automatic welding device for parts of a new energy vehicle chassis, including a mounting base 1, welding brackets 2 are fixedly installed on both sides of the mounting base 1, a control module 3 is installed on the top of the welding bracket 2, an electric push rod 4 is installed on the inner wall of the top of the welding bracket 2, a push plate 5 is installed on the bottom end of the electric push rod 4, a conveyor belt 6 is installed on the inner wall of the mounting base 1, a support plate 60 is fixedly installed on the bottom end of the push plate 5, the number of the support plates 60 is set to two groups, the two groups of support plates 60 are installed on the same axis at the bottom end of the push plate 5, and one side of the two groups of support plates 60 is installed There is a position sensor 7, one end of which is equipped with a motor 8, and the motor 8 is connected to a chain plate 80 through a transmission rod; a clamping assembly 9, a clamping assembly 9 is installed on one side of the push plate 5, and the clamping assembly 9 is used to clamp and fix the chassis parts; a switching assembly 10, a switching assembly 10 is installed on the top of the support plate 60, and the switching assembly 10 is used to switch the welding points on both sides of the chassis parts during welding; a supporting assembly 11, a supporting assembly 11 is installed on the top of the switching assembly 10, and the supporting assembly 11 is used to provide auxiliary support when welding on both sides of the chassis parts.

[0038] By setting the clamping component 9, dual monitoring of the automobile chassis parts and the clamping pad 93 is achieved, thereby improving the welding processing accuracy of the automobile chassis parts during welding. By setting the switching component 10 and the supporting component 11, the supporting angles of the gasket 1111 and the automobile chassis parts are changed, thereby improving the supporting flexibility of the gasket 1111 for the automobile chassis parts, and at the same time realizing the sequential switching of the "welding-support" processing effects on both sides of the automobile chassis parts.

[0039] like Figure 4 As shown, the clamping assembly 9 includes a mounting plate 91, which is mounted on one side of the push plate 5. The number of mounting plates 91 is set to two groups, and the two groups of mounting plates 91 are installed in the same axial direction on one side of the push plate 5. An electric telescopic rod 92 is installed at one end of the mounting plate 91, and a clamping pad 93 is fixedly installed at one end of the electric telescopic rod 92. The surface of the clamping pad 93 is provided with nitrile rubber, and an indicator needle 94 is installed at one end of the clamping pad 93. A scale plate 95 is installed at one end of the mounting plate 91, and position sensors 96 are installed at both ends of the scale plate 95.

[0040] The control module 3 controls the conveyor belt 6 through electrical signals to transport the automobile chassis parts that need to be welded to the bottom of the welding bracket 2. The control module 3 controls and pushes the push plate 5 to slide downward through the electric push rod 4. The push plate 5 drives the clamping assembly 9 to slide downward synchronously, so that the clamping assembly 9 and the side of the automobile chassis parts are in the same axial direction.

[0041] Subsequently, the control module 3 controls the electric telescopic rod 92 to extend. While the electric telescopic rod 92 is extended, it drives the clamping pad 93 at one end to approach and contact the side of the automobile chassis component. The two sides of the automobile chassis component are initially clamped and fixed by the two groups of electric telescopic rods 92. At the same time, the automobile chassis component is positioned by the position sensor 1 7 on the support plate 60. When the clamping pad 93 approaches and contacts the side of the automobile chassis component, the clamping pad 93 drives the indicator needle 94 to slide synchronously. While the indicator needle 94 slides, it slides above the scale plate 95 in the direction of the scale plate 95. When the clamping pad 93 clamps the side of the automobile chassis component in place, the operator can observe the position between the indicator needle 94 and the scale plate 95, and roughly judge the clamping state of the two groups of clamping pads 93. At the same time, the clamping accuracy of the clamping pad 93 is monitored in real time through the position sensor 2 96.

[0042] By setting the clamping pad 93, the automobile chassis parts are initially clamped and fixed when they are welded, thereby improving the welding processing accuracy of the automobile chassis parts during welding. At the same time, by setting the cooperation between the indicator needle 94, the scale plate 95 and the position sensor 96, the clamping situation of the clamping pad 93 is indicated in real time. At the same time, with the monitoring effect of the position sensor 7, dual monitoring of the automobile chassis parts and the clamping pad 93 is achieved, thereby further ensuring the welding processing accuracy of the automobile chassis parts.

[0043] like Figure 5 to Figure 6 As shown, the switching assembly 10 includes a rotating base 101, the number of the rotating base 101 is set to two groups, the two groups of rotating bases 101 are installed on the top of the support plate 60, a welding device 102 is installed at one end of the rotating base 101, and a chain plate 103 is installed on the top of the rotating base 101. The number of the chain plate 103 is set to two groups, and the two groups of chain plates 103 are installed on the top of the two groups of rotating bases 101. The outer surfaces of the two groups of chain plates 103 are sleeved with chains 1 04, the outer side of the chain 104 is connected to the chain plate 80, and two groups of chain plates 3 105 are sleeved on the inner side of the chain 104. The two groups of chain plates 3 105 are installed on both sides of the push plate 5. The inner walls of the two groups of chain plates 3 105 are installed with suction pipes 106, and one end of the suction pipe 106 is connected with the suction device. A clamping ring 107 is fixedly installed on the top of the rotating base 101, and an electromagnet 108 is installed in the bottom space of the clamping ring 107. The electromagnet 108 and the clamping ring 107 are installed in the same axial direction.

[0044] Subsequently, the control module 3 controls one group of welding devices 102 to weld the side welding points of the automobile chassis parts. When this group of welding devices 102 welds the side of the automobile chassis parts, the gasket 1111 provides auxiliary support for the other side of the automobile chassis parts. When one group of welding devices 102 completes the welding, the control module 3 starts the motor 8. After the motor 8 is started, the transmission rod drives the chain plate 1 80 to rotate. The chain plate 1 80 rotates while driving the chain 104 to rotate. The chain 104 drives one group of chain plates 2 103 to rotate. The chain plate 2 103 rotates while driving one group of rotating bases 101 to rotate. The rotating base 101 rotates while driving At the same time, the welding device 102 that has completed welding is driven to rotate, and the rotating base 101 rotates while driving the rotating box 111 on the top to rotate synchronously, so that the gasket 1111 is close to and contacts the side of the automobile chassis component. At the same time, the chain 104 drives another group of chain discs 103 to rotate synchronously, and the rotation of the other group of chain discs 103 drives another group of rotating bases 101 to rotate, and the rotation of the other group of rotating bases 101 drives another group of welding devices 102 to approach the other side of the automobile chassis component. At the same time, the welding fume generated during the welding process is sucked through the suction pipe 106 on the inner wall of the chain disc three 105 to complete the automatic welding of the automobile chassis components.

[0045] By setting the cooperation between the chain plate 2 103 and the chain plate 3 105, the switching effect between the two groups of welding devices 102 is achieved, and the two-way switching welding of the welding points on both sides of the automobile chassis parts is achieved. When welding the automobile chassis parts, there is no need for the operator to replace the welding points on both sides of the automobile chassis parts, thereby improving the welding efficiency when welding the automobile chassis parts. At the same time, the cooperation between the electromagnet 108 and the magnet disk 116 in the support component 11 is utilized, and the characteristics of the magnets that the same poles repel each other and the opposite poles attract each other are utilized to limit the rotation angle of the support component 11. When welding on one side of the automobile chassis parts, auxiliary support is simultaneously performed on the other side of the automobile chassis parts, thereby further ensuring the processing accuracy when welding the automobile chassis parts, and realizing the sequential switching of the "welding-support" processing effects on both sides of the automobile chassis parts.

[0046] like Figures 7 and 8As shown, the support assembly 11 includes a rotating box 111, which is mounted on the top of the rotating base 101, a transmission rod 112 is nested in the internal cavity of the rotating box 111, a turntable 113 is mounted on one end of the outer surface of the transmission rod 112, an elastic telescopic rod 114 is elastically mounted on one end of the rotating box 111, a chuck 115 is mounted on the bottom end of the elastic telescopic rod 114, the outer surface of the chuck 115 is in contact with the inner wall of the clamping ring 107, a magnet disk 116 is mounted on the bottom end of the chuck 115, a screw 117 is mounted on one end of the transmission rod 112, a sliding seat 118 is threadedly sleeved on the outer surface of the screw 117, a limiting rod 119 is sleeved on the outer surface of the sliding seat 118, the limiting rod 119 is mounted on one end of the rotating box 111, and a gasket 1111 is mounted on one end of the sliding seat 118 through a pin 1110. Then the operator The actual position of the motor vehicle chassis component is determined by the control module 3, and the electromagnet 108 is started through the control module 3. The magnetic pole of the electromagnet 108 is changed, so that the magnetic pole of the electromagnet 108 and the magnetic pole of the magnet disk 116 are the same magnetic pole. According to the principle that magnetic poles of the same name repel each other, the electromagnet 108 pushes the magnet disk 116 away, and the magnet disk 116 slides upward under the repulsive force of the electromagnet 108. While the magnet disk 116 slides, the chuck 115 and the elastic telescopic rod 114 are driven to slide upward synchronously, so that the outer surface of the chuck 115 is out of contact with the inner wall of the clamping ring 107. At this time, the operator can manually rotate the rotating box 111 according to the actual position of the welding point on the side of the automobile chassis component. While the rotating box 111 rotates, the transmission rod 112 and the screw 117 drive the sliding seat 118 to rotate synchronously, so that the backing ring 1111 at one end of the sliding seat 118 is aligned with the side of the automobile chassis component.

[0047] Then the operator rotates the turntable 113. While the turntable 113 rotates, the screw 117 is driven to rotate synchronously through the transmission rod 112. Under the rotation of the screw 117 and the fiber action of the limit rod 119, the sliding seat 118 slides along the direction of the screw 117. While the sliding seat 118 slides, it drives the pin 1110 and the gasket 1111 to approach and contact the side of the automobile chassis component, thereby achieving a supporting effect on the side of the automobile chassis component. At the same time, when the gasket 1111 contacts the side of the automobile chassis component, under the action of the pin 1110, the gasket 1111 can be rotated to fit the side of the automobile chassis component. At this time, one side of the automobile chassis component is in contact with the gasket 1111, and the other side of the automobile chassis component is in contact with the welding device 102.

[0048] By setting the linkage between the screw rod 117 and the sliding seat 118, when welding the automobile chassis parts, the operator can rotate the chuck 115 to achieve the auxiliary support effect of the sliding seat 118 and the gasket 1111 on the side of the automobile chassis parts. At the same time, through the magnetic attraction cooperation between the magnet disk 116 and the electromagnet 108, and the clamping effect between the chuck 115 and the clamping ring 107, the rotation angle of the gasket 1111 can be adjusted. By changing the supporting angle between the gasket 1111 and the automobile chassis parts, the supporting flexibility of the gasket 1111 on the automobile chassis parts is improved.

[0049] A method for using an automatic welding device for parts of a new energy vehicle chassis, the method comprising the following steps:

[0050] S1, the control module 3 controls and pushes the push plate 5 to slide downward through the electric push rod 4 and drives the clamping assembly 9 to slide downward synchronously. After the clamping assembly 9 slides into place, it initially clamps and fixes the two sides of the automobile chassis parts;

[0051] S2, the operator starts the electromagnet 108 according to the actual position of the welding point on the side of the automobile chassis component, and then rotates the support assembly 11, so that the support assembly 11 achieves a supporting effect on the side of the automobile chassis component;

[0052] S3, the control module 3 starts the motor 8, and realizes the sequential switching of the "welding-supporting" processing effects on both sides of the automobile chassis parts through the cooperation of the switching component 10 and the supporting component 11.

[0053] The working principle of the technical solution provided by the present invention is as follows:

[0054] The control module 3 controls the conveyor belt 6 through electrical signals to transport the automobile chassis parts that need to be welded to the bottom of the welding bracket 2. The control module 3 controls and pushes the push plate 5 to slide downward through the electric push rod 4. The push plate 5 drives the clamping assembly 9 to slide downward synchronously, so that the clamping assembly 9 and the side of the automobile chassis parts are in the same axial direction.

[0055] Subsequently, the control module 3 controls the electric telescopic rod 92 to extend. While the electric telescopic rod 92 is extended, it drives the clamping pad 93 at one end to approach and contact the side of the automobile chassis component. The two sides of the automobile chassis component are initially clamped and fixed by the two groups of electric telescopic rods 92. At the same time, the automobile chassis component is positioned by the position sensor 1 7 on the support plate 60. When the clamping pad 93 approaches and contacts the side of the automobile chassis component, the clamping pad 93 drives the indicator needle 94 to slide synchronously. While the indicator needle 94 slides, it slides above the scale plate 95 in the direction of the scale plate 95. When the clamping pad 93 clamps the side of the automobile chassis component in place, the operator can observe the position between the indicator needle 94 and the scale plate 95, and roughly judge the clamping state of the two groups of clamping pads 93. At the same time, the clamping accuracy of the clamping pad 93 is monitored in real time through the position sensor 2 96.

[0056] Subsequently, the operator starts the electromagnet 108 through the control module 3 according to the actual position of the welding point on the side of the automobile chassis component, and changes the magnetic pole of the electromagnet 108 so that the magnetic pole of the electromagnet 108 and the magnetic pole of the magnet disk 116 are the same. According to the principle that magnetic poles of the same name repel each other, the electromagnet 108 pushes the magnet disk 116 away, and under the repulsive force of the electromagnet 108, the magnet disk 116 slides upward, and the sliding of the magnet disk 116 drives the chuck 115 and the elastic telescopic rod 114 to slide upward synchronously, so that the outer surface of the chuck 115 is out of contact with the inner wall of the retaining ring 107. At this time, the operator can manually rotate the rotating box 111 according to the actual position of the welding point on the side of the automobile chassis component. While the rotating box 111 rotates, the transmission rod 112 and the screw 117 drive the sliding seat 118 to rotate synchronously, so that the backing ring 1111 at one end of the sliding seat 118 is aligned with the side of the automobile chassis component.

[0057] Then the operator rotates the turntable 113. While the turntable 113 rotates, the screw 117 is driven to rotate synchronously through the transmission rod 112. Under the rotation of the screw 117 and the fiber action of the limit rod 119, the sliding seat 118 slides along the direction of the screw 117. While the sliding seat 118 slides, it drives the pin 1110 and the gasket 1111 to approach and contact the side of the automobile chassis component, thereby achieving a supporting effect on the side of the automobile chassis component. At the same time, when the gasket 1111 contacts the side of the automobile chassis component, under the action of the pin 1110, the gasket 1111 can be rotated to fit the side of the automobile chassis component. At this time, one side of the automobile chassis component is in contact with the gasket 1111, and the other side of the automobile chassis component is in contact with the welding device 102.

[0058] Subsequently, the control module 3 controls one group of welding devices 102 to weld the side welding points of the automobile chassis parts. When this group of welding devices 102 welds the side of the automobile chassis parts, the gasket 1111 provides auxiliary support for the other side of the automobile chassis parts. When one group of welding devices 102 completes the welding, the control module 3 starts the motor 8. After the motor 8 is started, the transmission rod drives the chain plate 1 80 to rotate.
