DETAILED DESCRIPTION

[0042] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0043] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0044] Example 1:

[0045] An intelligent welding device for automobile parts, such as Figure 1-9As shown, it includes a support column 1, the outer wall of the support column 1 is rotatably connected to a turntable 2, and the inner wall of the turntable 2 is provided with multiple groups of circular array support rotating parts 3. In this embodiment, the specific number of groups of the support rotating parts 3 is not limited. Considering that loading, welding and unloading are three steps, this embodiment preferably has three groups of support rotating parts 3, and the support rotating parts 3 form a 120-degree circular array; the interior of the support column 1 is provided with a lifting drive part 8, and the moving end of the lifting drive part 8 is fixed to a support rod 7 by bolts, and a welding gun 6 is detachably provided at the bottom of the support rod 7. The welding gun 6 can be clamped on the inner wall of the support rod 7, or fixed to the bottom of the support rod 7 by bolts, or detachably installed on the inner wall of the support rod 7 by an elastic pin. A rotation drive component 4 for driving the turntable 2 to rotate is provided on the inner wall of one side of the support column 1, and a rotation drive component 2 5 for driving the support rotating part 3 to rotate is provided on one side of the support rod 7 of the support column 1.

[0046] The supporting rotating part 3 includes a turntable 2 9 rotatably connected to the inner wall of the turntable 1 2 , a clamping assembly 10 arranged above the turntable 2 9 , and a clamping driving member 13 arranged below the turntable 2 9 and used to drive the clamping assembly 10 .

[0047] The outer wall of the axis of the turntable 2 9 is fixed with a support seat 11 by bolts, and the top outer wall of the support seat 11 is provided with multiple limit columns 12 matching the spoke mounting holes. The limit columns 12 and the support seat 11 can be welded and fixed, or they can be connected detachably by flanges, threads, etc.

[0048] When the device is in use, the wheel rim can be placed on the turntable 2 9, and the clamping assembly 10 is driven by the clamping drive 13 to clamp the wheel rim. Then, the mounting holes on the spokes are aligned with the limit columns 12 and placed on the support seat 11 for support. Then, the turntable 1 2 is driven to rotate by the rotating drive assembly 1 4, so that the supporting rotating part 3 loaded with the wheel hub rotates to the bottom of the support rod 7, and the lifting drive part 8 controls the support rod 7 to descend to the welding position. Then, the rotating drive assembly 2 5 drives the group of supporting rotating parts 3 to rotate for welding. While welding, the wheel hub that is rotated to the downstream after welding can be taken out, and at the same time, another group of empty supporting rotating parts 3 can be loaded.

[0049] This device is provided with a turntable 2, which is equipped with multiple groups of supporting rotating parts 3. During the process of welding one of the wheel hubs by the welding gun 6, the welded wheel hub can be unloaded at the same time, and the vacant supporting rotating parts 3 can be loaded at the same time, so that the loading, welding and unloading of the entire welding process can be carried out simultaneously, thereby improving the efficiency of the entire welding process.

[0050] In order to solve the clamping problem; Figure 3As shown, the clamping assembly 10 is composed of a plurality of clamping rollers 17 which are slidably connected to the turntable 2 9 via a slider 16 and arranged in a circular array. In this embodiment, there is no limitation on the specific number of the clamping rollers 17, which can be any number greater than three. In this embodiment, three groups are preferably arranged in a 120-degree circular array.

[0051] The clamping assembly 10 also includes a driving disk 18 rotatably connected to the inner side of the bottom of the turntable 2 9. The inner wall of the driving disk 18 is provided with inclined slide grooves 14 that match the number of clamping rollers 17. The bottom of the slider 16 is movably limited and engaged with the inner wall of the inclined slide groove 14 through a limiting rod 15. In this embodiment, the specific shape of the inclined slide groove 14 is not limited, and it can be a linear inclined arrangement or an arc-shaped arrangement.

[0052] When the driving disc 18 rotates, it can limit the limiting rod 15 through the inclined sliding groove 14 to drive the multiple sliders 16 to move, thereby achieving the clamping and releasing of the wheel rim.

[0053] This device clamps the wheel rim by providing a clamping assembly 10, thereby preventing the wheel rim from moving during welding and ensuring welding accuracy. In addition, multiple clamping rollers 17 are provided for clamping and driven by the rotation of the driving disk 18, so that the multiple clamping rollers 17 can move synchronously, so that the axis of the clamped wheel rim coincides with the rotation center of the driving disk 18, thereby facilitating the positioning of the wheel rim and further increasing the accuracy.

[0054] In order to solve the clamping drive problem; such as Figure 4 As shown, the clamping drive member 13 includes a gear ring 19, a rack 20 and a support block 22. The rack 20 is slidably connected to the surface of the turntable 2 9, and the rack 20 is engaged with the outer wall of the gear ring 19. The gear ring 19 is fixed to the outer wall of the drive disk 18 by bolts, and the support block 22 is welded to the surface of the turntable 2 9.

[0055] An insulating spring 21 is buckled on the opposite side of the support block 22 and the rack 1 20 .

[0056] An electromagnet 23 is fixed to the side wall of the rack 1 20 by bolts, and another electromagnet 23 is fixed to the side wall of the rack 1 20 facing the electromagnet 23 by bolts. The magnetic poles of the two electromagnets 23 on opposite sides are opposite.

[0057] When the electromagnet 23 is energized, suction is generated therebetween, thereby driving the rack 20 to slide, thereby driving the drive disk 18 to rotate through the gear ring 19. When the electromagnet 23 is de-energized, the rack 20 is reset by the elastic force of the insulating spring 21.

[0058] In order to solve intelligent problems; Figure 5As shown, a conductive ring 25 is fixed to the outer wall of the bottom of the turntable 2 located on the outer circumference of the supporting rotating part 3, and an elastic conductive column 24 is provided on the side wall of the support block 22 to contact and cooperate with the conductive ring 25. A cam conductive ring 27 is fixed to the outer wall of the support column 1 located at the bottom of the turntable 2 by bolts, and an elastic conductive column 26 is provided on the side wall of the conductive ring 25 to contact and cooperate with the cam conductive ring 27. The elastic conductive column 24 is electrically connected to the electromagnet 23.

[0059] The cam conductive ring 27 is connected to an external power source, and the protruding direction of the cam conductive ring 27 is the welding position.

[0060] When the conductive ring 25 rotates to the welding station as the turntable 1 rotates, the elastic conductive column 26 contacts the cam conductive ring 27. The current flows along the cam conductive ring 27-elastic conductive column 26-conductive ring 25-elastic conductive column 1 24 to the electromagnet 23, thereby energizing it. When the group of conductive rings 25 rotates away from the welding station, the elastic conductive column 26 is no longer in contact with the cam conductive ring 27, and the electromagnet 23 is de-energized.

[0061] This device uses the elastic conductive column 1 24, the conductive ring 25, the elastic conductive column 26 and the cam conductive ring 27 to power the electromagnet 23. On the one hand, it can automatically energize and clamp the supporting rotating part 3 when it is located at the welding station, and automatically release the clamp when it is located at the loading and unloading station, thereby realizing intelligent control. On the other hand, for the entire supporting rotating part 3 that needs to be rotated, the elastic conductive column 1 24 and the conductive ring 25 are used as a transition, so that the rotating part does not need to be connected to the power supply, thereby preventing the occurrence of wire harness entanglement and increasing safety and reliability.

[0062] In order to solve the rotation drive problem of the turntable 29; Figure 6 As shown, the rotary drive assembly 25 includes a gear ring 28 fixed to the top surface of the turntable 29, a motor 1 33 fixed to the inner wall of the support column 1 by bolts, and a rack 2 30 slidably connected to the radial direction of the support column 1. The number of gear rings 28 is the same as the number of turntables 29. The rack 2 30 is connected to the inner wall of the support column 1 through a spring 1 31. The bottom of the rack 2 30 is rotatably connected to a gear 29, and the outer wall of the output shaft of the motor 1 33 is connected to a gear 2 32 through a key.

[0063] When turntable 2 9 moves toward the welding station, gear 1 29 will shrink due to the squeezing force of the ring gear 28, causing gear 1 29 to move toward gear 2 32 until gear 1 29 and gear 2 32 are engaged. Then, turntable 2 9 reaches the welding station. At this time, motor 1 33 is started, which drives gear 2 32 to rotate, thereby driving the ring gear 28 and turntable 2 9 to rotate through gear 1 29. When turntable 2 9 rotates away from the welding station, gear 1 29 is moved outward by the elastic force of spring 1 31, and gear 1 29 and gear 2 32 are no longer engaged.

[0064] This device provides a rotation drive assembly 25 to rotationally drive the turntable 29. On the one hand, by utilizing the position characteristics, one group of motors 1 33 can meet the driving needs of three groups of turntables 2 9, reducing the power source layout while also ensuring that the position of motor 1 33, which is the only power source, is fixed to prevent wiring harness entanglement. On the other hand, by utilizing the displaceable characteristics of gear 1 29, it can also be ensured that turntable 2 9 rotates only when it is completely in the welding position, ensuring safety while also saving energy.

[0065] In order to solve the rotation problem of turntable 1 2, Figure 7 As shown, the rotary drive assembly 1 4 includes a gear 3 34 and a motor 2 36. The motor 2 36 is fixed to the inner wall of the support column 1 by bolts, and the gear 3 34 is fixed to the output shaft of the motor 2 36. The gear 3 34 and the motor 2 36 can be connected by a key, a flange or welding. The turntable 1 2 is engaged with the outer wall of the gear 3 34 through the tooth groove 35 opened on its inner wall.

[0066] When the motor 2 36 is started, it can drive the gear 3 34 to rotate, thereby driving the turntable 1 2 to rotate through the gear 3 34 .

[0067] In order to solve the rotation limit problem, such as Figure 9 As shown, the inner wall of the turntable 1 2 is slidably connected with a plurality of arc-surface protrusions 41, and the arc-surface protrusions 41 are connected to the turntable 1 2 through a spring 2 40, and the number and position of the arc-surface protrusions 41 are the same as those of the supporting rotating part 3. The inner wall of the support column 1 is provided with a card slot 42 matching the arc-surface protrusion 41, and the inner wall of the card slot 42 is fixed with a press-close signal switch 43.

[0068] When the turntable 1 2 rotates, the arc-surface protrusion 41 rotates through the arc-surface protrusion 41 until it rotates to 120 degrees, and the arc-surface protrusion 41 is stuck in the card slot 42, so that the press-close signal switch 43 is pressed, generating an electrical signal, thereby controlling the motor 2 36 to be closed according to the electrical signal.

[0069] This device, by providing a press-close signal switch 43, uses the arc-surface protrusion 41 to press the press-close signal switch 43 to generate an electrical signal, thereby controlling the closing node of the motor 2 36, and uses the engagement of the arc-surface protrusion 41 with the card slot 42 to ensure the position locking, thereby increasing the accuracy of the work station switching.

[0070] When the present embodiment is in use, the wheel rim can be placed above the turntable 2 9, and then the mounting holes on the spokes are aligned with the limit columns 12 and placed above the support seat 11 for support. Subsequently, the motor 2 36 is started to drive the gear 3 34 to rotate, thereby driving the turntable 1 2 to rotate through the gear 3 34, until the turntable 2 9 loaded with the hub rotates to the bottom of the support rod 7. At this time, on the one hand, the gear 1 29 is squeezed by the ring gear 28 and shrinks, thereby causing the gear 1 29 to move toward the gear 2 32, until the gear 1 29 is engaged with the gear 2 32, and the turntable 2 9 reaches the welding position. At this time, the motor 1 33 is started, which drives the gear 2 32 to rotate, thereby driving the ring gear 28 and the turntable 2 9 to rotate through the gear 1 29. On the other hand, the elastic conductive column 2 26 and the cam The conductive ring 27 is in contact, and the current flows along the cam conductive ring 27-elastic conductive column 26-conductive ring 25-elastic conductive column 1 24 to the electromagnet 23, thereby energizing it. Then the lifting drive unit 8 drives the support rod 7 to descend, and welding is performed through the welding gun 6. At the same time, the wheel hub that has rotated to the downstream after welding can be taken out, and another set of empty supporting rotating parts 3 can be loaded. After this group of welding is completed, the motor 2 36 is started here to drive the turntable 1 2 to rotate, and the welded wheel hub rotates away from the welding station. At this time, on the one hand, the gear 1 29 is moved outward by the elastic force of the spring 1 31, and the gear 1 29 is not engaged with the gear 2 32. On the other hand, the elastic conductive column 26 is not in contact with the cam conductive ring 27, and the electromagnet 23 is powered off. This cycle can be repeated.

[0071] Example 2:

The support rod 7 is fixed to the side wall of the connecting block 39 by bolts.

[0073] The transmission wheel 37 at the bottom is engaged with the top outer wall of the second rack 30 .

[0074] In this embodiment, the specific types of the transmission wheel 37 and the transmission belt 38 are not limited, and they can be pulleys, sprockets or drums. Similarly, the corresponding transmission belt 38 can be a transmission belt, a transmission chain or a rope. In this embodiment, preferably, the transmission wheel 37 is a pulley and the transmission belt 38 is a transmission belt.

[0075] When this embodiment is in use, when the turntable 2 9 rotates to the welding station, the rack 2 30 moves, thereby driving the transmission wheel 37 at the bottom to rotate, thereby moving the transmission belt 38, and driving the connection block 39 to rise and fall.

[0076] This device, on the basis of setting up a lifting drive unit 8 to control the lifting of the support rod 7, the lifting drive unit 8 is designed to use a combination of a transmission wheel 37 and a transmission belt 38, and on this basis, the transmission of the rack 2 30 and the transmission wheel 37 is utilized, so that the movement of the rack 2 30 itself can be used for driving, which reduces the layout of the power source and also increases the synchronization of the device.

[0077] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
