Description

Technical Field

[0001] The present application relates to the technical field of automobile manufacturing, and in particular to a molding device for automobile door panel processing. Background Art

[0002] Car door panels are the doors on cars. Car doors are generally composed of three parts: door body, door accessories and interior cover. Modular sound-absorbing cotton will be installed on the car door panels. Sound-absorbing cotton is a kind of man-made inorganic fiber. It uses quartz sand, limestone, dolomite and other natural minerals as the main raw materials, and is melted into glass with some chemical raw materials such as soda ash and borax. The sound absorption rate of sound-absorbing cotton is high, and the sound insulation and heat insulation properties are very good.

[0003] The sound-absorbing cotton is usually welded and fixed on the car door panel. Before welding, it is necessary to pre-install each plastic component to the corresponding position of the door panel body according to its respective predetermined position, and then perform ultrasonic welding. Ultrasonic welding generally uses high-frequency mechanical vibration to weld materials. Generally, an ultrasonic welder is used to weld plastic products or fabrics. When using an ultrasonic welder to weld fabrics, it is generally necessary to overlap the fabrics and place them on the welding table. The welding of the materials is achieved by moving the ultrasonic welder's welding head downward. The ultrasonic welding head usually needs to be installed on a robotic arm, and the position to be welded is welded through the automatic control of the robotic arm. The robotic arm refers to a complex system with high precision, multiple inputs and multiple outputs, high nonlinearity, and strong coupling. Due to its unique operational flexibility, it has been widely used in industrial assembly, safety and explosion-proof and other fields.

[0004] When welding sound-absorbing cotton to a car door panel, since the surface of the car door panel is curved, in order to ensure accurate welding, the car door panel usually needs to be placed on a special welding table before welding. The existing robotic arm is usually arranged on one side of the welding table, but the welding table and the robotic arm are relatively independent and separated. When the robotic arm is welding, since the two are relatively independent, the ultrasonic welding head of the robotic arm needs to be calibrated between the car door panels before each welding. Only after the calibration is completed can ultrasonic welding continue. The calibration steps are relatively cumbersome, resulting in low welding efficiency. In addition, during the welding process, when the welding table and the robotic arm move relative to each other, the welding position will be inaccurate, resulting in welding errors. Summary of the invention

[0005] In order to improve welding efficiency and reduce welding errors, the present application provides a shaping device for automobile door panel processing.

[0006] The present application provides a shaping device for automobile door panel processing, which adopts the following technical solution: A shaping device for automobile door panel processing comprises a welding plate for installing the automobile door panel, a clamping assembly arranged on the welding plate and used to fix the automobile door panel, and a mechanical arm arranged on one side of the welding plate and used to weld the automobile door panel, wherein the mechanical arm is provided with an ultrasonic welding head, and fixing frames for supporting the welding plate and the mechanical arm are provided under the welding plate and under the mechanical arm, and a connection stabilization device is provided between the two fixing frames to connect the welding plate and the mechanical arm into a whole and to maintain relative stability between the two, and a pair of fixed support rods are provided in parallel on the two fixing frames, and the connection stabilization device is connected and fixed to two corresponding fixed support rods on the two sets of fixing frames.

[0007] By adopting the above technical scheme, when welding and assembling the parts on the automobile door panel, the automobile door panel is first placed on the welding plate and fixed by the clamping assembly, and finally the ultrasonic welding head is controlled by the robotic arm to perform fixed welding. Since the welding plate and the fixing frames of the robotic arm are separately and independently set, relative sliding will occur during the welding process. The fixed support rods on the corresponding fixing frames are connected by the set connection stabilization device, so that the two fixing frames are connected and fixed. During the welding process, the robotic arm and the welding plate are relatively fixed. When the fixing frame on the welding plate moves, the fixing frame on the robotic arm also moves, avoiding the need to repeatedly calibrate and position the ultrasonic welding head, saving time and improving efficiency, while avoiding welding errors.

[0008] Preferably, the connecting and stabilizing device comprises two groups of stabilizing components with the same structure, the two groups of stabilizing components are mounted on two fixed support rods on corresponding fixed frames, a connecting component is arranged between the two groups of stabilizing components, and the two groups of stabilizing components are connected and fixed by the connecting component.

[0009] By adopting the above technical solution, when the two fixing frames are connected and fixed, the fixed support rods on the two fixing frames are fixed by the stabilizing assembly, and the two sets of stabilizing assemblies are connected and fixed by the connecting assembly, so that the two sets of fixing frames form an integral structure.

[0010] Preferably, the stabilizing assembly includes a stabilizing rod transversely arranged on two fixed support rods and a pair of fixing members correspondingly arranged on the two fixed support rods, the two ends of the stabilizing rod are overlapped on the corresponding fixed support rods, the two fixing members are arranged at positions close to the two ends of the stabilizing rod, and the fixing members fix the ends of the stabilizing rod to the corresponding fixed support rods.

[0011] By adopting the above technical solution, the two ends of the stabilizer bar can be overlapped on the two fixed support rods, and the two ends of the stabilizer bar can be fixed to the two fixed support rods through the fixing parts, thereby improving the connection stability between the stabilizer bar and the fixed frame. Compared with the connection between the stabilizer bar and a single fixed support rod, it has better stability and makes it inconvenient to move the fixed frame.

[0012] Preferably, the connecting assembly comprises a connecting rod disposed between the ends of two stabilizing rods on the two groups of stabilizing assemblies, and both ends of the connecting rod are connected and fixed to the corresponding stabilizing rods.

[0013] By adopting the above technical solution, after the stabilizing rods on the two fixing frames are fixed, the connecting rod is set between the corresponding two fixed support rods, and the two ends of the connecting rod are fixed to the ends of the stabilizing rod, so that the two sets of stabilizing components are connected into a whole.

[0014] Preferably, the fixing member includes a fixing ring that is slidably fitted on the fixed support rod and a fixing buckle arranged on the fixing ring, the fixing buckle is clamped onto the stabilizing rod, and a fixing bolt is threadedly connected to the fixing ring, and the fixing bolt passes through the fixing ring and is tightened onto the fixed support rod.

[0015] By adopting the above technical solution, when fixing the two ends of the stabilizer bar, first slide and adjust the position of the fixing ring to allow the fixing ring to slide close to the stabilizer bar, and then connect it to the stabilizer bar through the fixing buckle to connect and fix the stabilizer bar and the fixed support rod, and finally reinforce it with the fixing bolts.

[0016] Preferably, a pair of stabilizing rods are provided, and the two stabilizing rods are arranged in parallel on the corresponding two fixed support rods and fixed by set fixing parts. A rectangular structure is formed between the two stabilizing rods and the two fixed support rods. A pair of connecting rods are provided for connecting the corresponding two stabilizing rods.

[0017] By adopting the above technical solution, a pair of stabilizing rods can form a stable planar rectangular frame structure with two fixed support rods on the fixing frame, thereby improving the connection strength between the stabilizing assembly and the fixing frame and preventing the fixing frame from shaking around a single stabilizing rod.

[0018] Preferably, the two stabilizing bars are slidably arranged on two fixed support bars, and a control component for controlling the relative sliding of the two stabilizing bars is arranged between the two stabilizing bars. The control component includes a scissors-type member arranged between the two stabilizing bars, and the scissors-type member can make the two stabilizing bars approach each other or move away from each other. A driving member for driving the two stabilizing bars to move is also arranged on the two stabilizing bars.

[0019] By adopting the above technical solution, when adjusting the two stabilizing bars to slide on the fixed support bar, the scissors-type parts can make the two stabilizing bars relatively close or relatively far away to achieve synchronous action, and the driving parts can be used to make the two stabilizing bars slide and adjust each other. Precise adjustment can be achieved during the adjustment process, allowing the stabilizing bars to be slowly inserted into the fixed buckles.

[0020] Preferably, the driving member comprises a driving screw rotatably arranged on the two stabilizing rods, the driving screw is provided with forward and reverse bidirectional threads, and the forward and reverse bidirectional threads on the driving screw are connected with the corresponding stabilizing rod threads.

[0021] By adopting the above technical solution, when installing the two stabilizing bars on the corresponding fixed support bars, the staff rotates the driving screw, and under the action of the positive and negative bidirectional threads, the two stabilizing bars can be moved closer to or away from each other on the fixed support bar, so that the ends of the stabilizing bars are clamped on the fixed buckles, allowing the stabilizing bars to be connected to the fixed frame as a whole.

[0022] Preferably, both ends of the connecting rod are rotatably connected to the ends of the two stabilizing rods, so that the two stabilizing rods form a displacement difference in the horizontal direction.

[0023] By adopting the above technical solution, when it is necessary to install the stabilizer bar, the horizontal displacement distance between the two stabilizer bars is adjusted according to the actual placement position of the two fixing frames on site, and then the two stabilizer bars and the connecting rod are installed on the corresponding fixed support rods on the fixing frames. After the installation is completed, the rotating bolts are tightened to prevent the two stabilizer bars from rotating relative to each other. Therefore, the set connecting rod can be applied to fixing frames of different sizes and can be quickly adjusted at the installation site according to actual needs, thereby improving the efficiency of installation and fixation.

[0024] Preferably, the stabilizing rod is a telescopic structure, which includes a fixed portion and a pair of movable portions, and the two movable portions are slidably arranged at both ends of the fixed portion so that the ends of the movable portions can overlap on the corresponding fixed support rods.

[0025] By adopting the above technical solution, due to the different sizes of the automobile door panels to be welded, it is necessary to set corresponding welding plates and fixing frames of different sizes. When encountering a larger fixing frame, the distance between the two fixed support rods is larger. Through the stabilizer bar of the telescopic structure, the controller can extend and retract different lengths, so that the movable part can be normally overlapped on the fixed support rod, thereby connecting the two fixed support rods, thereby improving the stability of the connection between the stabilizer bar and the two fixed support rods.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. During the welding process of automobile door panels and other parts, the fixing frame on the welding plate and the fixing frame on the mechanical arm are connected into a whole through the provided connection and stabilization device, the two stabilizing bars on each set of fixing frames can be overlapped on the corresponding fixed support bars, and the stabilizing bars and the fixed support bars are connected and fixed through the provided fixing pieces, and finally the two adjacent stabilizing bars are connected and fixed through the connecting rod; 2. The stabilizer bar is a telescopic structure. When the distance between the two fixed support rods is large, the two ends of the movable part are extended from the fixed part so that the movable part can be overlapped and connected to the fixed support rod and fixed by fixing parts, so that the stabilizer assembly can adapt to fixed frames of different sizes.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a shaping device for processing automobile door panels.

The welding plate 1 is a rectangular plate-shaped structure. A support seat 11 for supporting the automobile door panel is arranged on the surface of the welding plate 1. When welding the sound-absorbing cotton to the automobile door panel, the automobile door panel is first mounted on the welding plate 1, and a plurality of clamping assemblies 12 are arranged on the welding plate 1. The automobile door panel is fixed on the welding plate 1 by the clamping assemblies 12 to prevent the automobile door panel from moving during the welding process; a three-dimensional rectangular frame structure is arranged under the welding plate 1. A fixing frame 3 is provided, a welding plate 1 is installed on the fixing frame 3, a robotic arm 2 is provided on one side of the fixing frame 3, an ultrasonic welding head 21 for welding is provided on the robotic arm 2, and a fixing frame 3 with the same structure is provided under the robotic arm 2, so that the robotic arm 2 can be fixed on the fixing frame 3 to provide stable support; in the embodiment of the present application, the two fixing frames 3 have the same structure but different sizes, and the two fixing frames 3 are relatively independently arranged, the robotic arm 2 can perform welding operations on automobile door panels of different specifications and models, but the corresponding welding plate 1 needs to be replaced.

[0035] Reference Figure 1 and Figure 2 A connection and stabilization device is provided between the two fixing frames 3 to connect the two into a whole. The connection and stabilization device is provided to make the two form a whole, ensure that there is no relative sliding, so that the robot arm 2 can perform accurate welding. A pair of fixed support rods 31 are fixed in parallel on the two fixing frames 3. The two fixed support rods 31 are arranged at a position close to the lower end of the fixing frames 3 on the corresponding fixing frames 3. The two fixed support rods 31 on the two groups of fixing frames 3 are also parallel to each other. The connection and stabilization device connects and fixes the two fixed support rods 31 on the two groups of fixing frames 3. The connection and stabilization device includes two groups of stabilization components 4, which are arranged on the corresponding fixing frames 3, and the two groups of stabilization components 4 have the same structure. According to the size of the corresponding fixing frames 3, the stabilization components 4 of the same size are matched, and the stabilization components 4 are installed on the two fixed support rods 31. A connection component 5 is provided between the two groups of stabilization components 4, and the connection component 5 can connect and fix the two groups of stabilization components 4, so as to fix the two fixing frames 3.

[0036] The stabilizing assembly 4 includes a stabilizing rod 41 which is arranged across the two fixed support rods 31. Both ends of the stabilizing rod 41 are overlapped on the corresponding fixed support rods 31, and at least two stabilizing rods 41 are arranged. In the embodiment of the present application, two are taken as an example. The two stabilizing rods 41 are arranged in parallel and perpendicular to the two fixed support rods 31. The two stabilizing rods 41 and the two fixed support rods 31 form a stable planar rectangular frame structure on the fixing frame 3. A pair of fixing members 42 are arranged on each fixed support rod 31. The two fixing members 42 are arranged at the corresponding ends of the stabilizing rod 41. The fixed support rod 31 and the stabilizing rod 41 are fixed by the fixing members 42, so that the two stabilizing rods 41 can be firmly fixed on the fixing frame 3.

[0037] Reference Figure 2 and Figure 3 The fixing member 42 includes a fixing ring 421 that is slidably fitted on the fixing support rod 31, and the fixing ring 421 is sleeved on the fixing support rod 31. An L-shaped fixing buckle 422 is fixed on the fixing ring 421 and on the side facing the stabilizing rod 41. A clamping interface for clamping the end of the stabilizing rod 41 is formed between the L-shaped fixing buckle 422 and the fixing ring 421. When the end of the stabilizing rod 41 is overlapped on the fixing support rod 31, the fixing ring 421 is slid and the fixing buckle 422 is clamped and fitted to the stabilizing rod 41; a fixing bolt 423 is threadedly connected to the fixing ring 421, and the fixing bolt 423 passes through the fixing ring 421 and is tightened to the fixing support rod 31. When the fixing ring 421 slides to the corresponding position, the fixing bolt 423 is tightened to fix the stabilizing rod 41 on the fixing support rod 31.

[0038] The connecting assembly 5 includes a connecting rod 51 for connecting and fixing the two stabilizing rods 41 on the corresponding two groups of stabilizing assemblies 4. The connecting rod 51 is arranged between the ends of the two stabilizing rods 41, and the two ends of the connecting rod 51 are connected to the ends of the stabilizing rods 41. Due to the different sizes of the two groups of fixing frames 3, when the stabilizing rod 41 is installed on the corresponding fixed support rod 31, the two stabilizing rods 41 on the two groups of fixing frames 3 are not in the same straight line, and a displacement difference is formed in the horizontal direction. Therefore, the connecting rod 51 is tiltedly arranged between the two stabilizing rods 41; the two ends of the connecting rod 51 are rotatably connected to the two ends of the stabilizing rod 41, and rotating bolts 52 are arranged at the two ends of the connecting rod 51. When the stabilizing rod 41 needs to be installed, the horizontal displacement distance between the two stabilizing rods 41 is adjusted according to the actual placement position of the two fixing frames 3 on site, and then the two stabilizing rods 41 and the connecting rod 51 are installed on the corresponding fixed support rods 31 on the fixing frame 3. After the installation is completed, the rotating bolts 52 are tightened to prevent the two stabilizing rods 41 from rotating relative to each other.

[0039] Reference Figure 2 and Figure 3The two stabilizing rods 41 can slide on the corresponding two fixed support rods 31, and the two stabilizing rods 41 can approach or move away from each other. A control component 6 for controlling the movement of the two stabilizing rods 41 is arranged between the two stabilizing rods 41. The control component 6 includes a scissor-type member arranged between the two stabilizing rods 41. The scissor-type member includes two cross-arranged scissor-type rods 61 and a pair of sliding sleeves 62 slidingly fitted on each stabilizing rod 41. The two ends of the scissor-type rods 61 are hinged to the corresponding sliding sleeves 62, and a rotating shaft is arranged in the middle of the two cross-arranged scissor-type rods 61. The two scissor-type rods 61 rotate around the rotating shaft, so that the scissor-type member is more stable during use. When it is necessary to control the two stabilizing rods 41 to be relatively close or away from each other, the synchronous movement is achieved through the arranged scissor-type member. The control assembly 6 also includes a driving member arranged on the two stabilizing rods 41, and the driving member includes a driving block 63 fixed on each stabilizing rod 41 and a driving screw 64 passing through the two driving blocks 63. The driving screw 64 is arranged above the two stabilizing rods 41, and the driving screw 64 is perpendicular to the two stabilizing rods 41. The driving screw 64 is provided with forward and reverse bidirectional threads, and the forward and reverse bidirectional threads on the driving screw 64 are threadedly connected with the corresponding driving blocks 63. A handle 65 is installed at one end of the driving screw 64. When the two stabilizing rods 41 are installed on the fixing frame 3, the rotation of the driving screw 64 is controlled by the handle 65, so that the two stabilizing rods 41 are gradually stretched on the fixed support rod 31 until the two ends of the stabilizing rods 41 are clamped into the card interface.

[0040] Reference Figure 2 and Figure 3 The stabilizing rod 41 is a telescopic structure, which includes a fixed portion 411 and a pair of movable portions 412. The fixed portion 411 is arranged between the two fixed support rods 31, and the two movable portions 412 are symmetrically arranged at both ends of the fixed portion 411, and the movable portion 412 is slidably inserted into the fixed portion 411. The two movable portions 412 can extend from the fixed portion 411, and the ends of the movable portions 412 are overlapped on the corresponding fixed support rods 31, and the ends of the movable portions 412 are snapped into the corresponding card interfaces. 3 is different in size. When the distance between the two fixed support rods 31 is large, the two ends of the movable part 412 can be extended from the fixed part 411 to be overlapped on the fixed support rod 31, so as to accommodate more fixing frames 3; the limiting bolts 413 are threadedly connected on the fixed part 411 and close to the two ends thereof. When the movable part 412 is extended from the fixed part 411 to the right position, the limiting bolts 413 are tightened to avoid relative sliding between the movable part 412 and the fixed part 411 during use.

[0041] Reference Figure 2 and Figure 4The fixing member 42 also includes a pair of limit plates 424 arranged on the fixing ring 421, and the two limit plates 424 are symmetrically fixed at the opening of the fixing ring 421. The two limit plates 424 are arranged on one side of the fixing ring 421 close to the stabilizing rod 41, and the two limit plates 424 are slidably arranged on both sides of the fixed support rod 31. A plurality of limit grooves 425 are opened on the movable portion 412 of the stabilizing rod 41, and the length direction of the limit grooves 425 is the same as the length direction of the fixed support rod 31, and the plurality of limit grooves 425 are evenly arranged along the length direction of the movable portion 412. The limit plates 424 can be plugged into and matched with the limit grooves 425. When the movable portion 412 slides to the corresponding card interface, the limit plates 424 are slidably plugged into the corresponding limit grooves 425. When the stabilizing rod 41 is connected and fixed to the two fixing frames 3, it can prevent the stabilizing rod 41 from sliding along the length direction of the stabilizing rod 41, and prevent the movable portion 412 from sliding out of the card interface, thereby improving the connection strength and stability between the two fixing frames 3.

[0042] The implementation principle of a shaping device for automobile door panel processing in an embodiment of the present application is as follows: when connecting and fixing two fixing frames 3, firstly, according to the length of the fixing frames 3, the movable part 412 on the stabilizing rod 41 is slid out to a suitable distance, and the movable part 412 is set on the corresponding fixed support rod 31, and the sliding adjustment fixing ring 421 is used to allow the movable part 412 to be snapped onto the fixed buckle 422, and the limiting plate 424 is inserted into the limiting groove 425, and then the fixing bolt 423 is tightened and fixed to connect and fix the stabilizing rod 41 and the fixed support rod 31, so that the two fixing frames 3 are connected as a whole through the stabilizing rod 41 and the connecting rod 51, thereby maintaining the relative stability between the two fixing frames 3.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
