Description

Technical Field

[0001] The utility model relates to the technical field of welding of automotive parts, and particularly relates to a welding device for automotive parts. Background Art

[0002] Automotive parts are the various units that make up an entire vehicle and products that serve the vehicle. There is a wide variety of automotive parts, such as automotive chassis, automotive body, engines, etc. These parts not only control and transmit power but also bear the functions of supporting and protecting drivers and passengers. For automobile manufacturing, stamping, welding, painting, and final assembly are the four major technological processes in automobile manufacturing. Among them, the welding process has very strict requirements for welding precision and welding speed. Since the welding efficiency of workers is low and the welding precision is difficult to meet the requirements of the welding process, welding robots are often used in the welding process of automobile manufacturing. By using laser or arc welding, the welding areas of two automotive parts to be welded together are heated, so that the welding areas of the two automotive parts are melted. In this way, the molecular structure of the welding area between the two automotive parts can be disrupted, and by utilizing the rearrangement of molecules, the molecules in the welding area of the two automotive parts can be integrated together, and then the two automotive parts can be welded together. Compared with ordinary welding, laser or arc welding has higher strength and hardness.

[0003] During the welding process of automotive parts, it is usually necessary to use inert gases such as argon for protection to prevent damage to the welding area. Moreover, high temperatures during the welding process may generate welding fumes and slag. For the surrounding workers during long-term work, they are not only prone to discomfort but also likely to have an impact on the health of the workers. Therefore, a separate welding room is used to isolate the welding operation of automotive parts from the working area of the workers. However, the loading and unloading of automotive parts still need to be completed by workers. Therefore, after the welding operation of automotive parts is completed, workers need to enter the welding room to complete the loading and unloading operation of automotive parts. Therefore, the welding operation still causes harm to the workers. In addition, the positioning and clamping efficiency of automotive parts will affect the production speed of the welding process of automotive parts. If the positioning and clamping range of automotive parts is only limited around the welding equipment, due to the limited positioning and clamping range of automotive parts and the relatively complex operation of the positioning and clamping operation of automotive parts, it may lead to difficulties in the positioning and clamping process of automotive parts, making it difficult to effectively carry out the positioning and clamping of automotive parts, thus affecting the production speed of the welding process. Therefore, in order to better carry out the positioning and clamping efficiency work of automotive parts and improve the production speed of the welding process, corresponding optimizations and improvements need to be made in welding. This can not only reduce the harm to workers but also make the positioning and clamping operations of automotive parts more convenient, so as to improve the production speed of the welding process.

[0009] Preferably, a handle is arranged on the tooling plate. The handle adopts an n-shaped rod structure. The bottom end of the handle is installed on the tooling plate.

[0012] The beneficial effects of the present utility model are as follows: First, through the welding chamber provided in the present utility model, a separate space is created for the welding platform to reduce the harm to workers caused by inert protective gases such as argon, welding fumes, and welding slag. Through the fixed plate, positioning bolts, and springs provided in the present utility model, the limit cover is supported and positioned, enabling the tooling plate to be quickly positioned on one side of the support plate, thereby improving the positioning efficiency of automotive parts and further increasing the production speed of the welding process. Moreover, through the baffle provided in the present utility model, the two positioning mechanisms are separated, so that the positioning mechanism on one side of the baffle is located inside the welding chamber, and the positioning mechanism on the other side of the baffle is located outside the welding chamber, thus separating the loading and unloading operations from the welding operations to facilitate the simultaneous progress of the loading and unloading operations and the welding operations.

[0014] Third, through the positioning groove opened on the welding platform, when the positioning mechanism is located inside the welding chamber, the universal wheels are suspended above the positioning groove. Therefore, the limit cover and the tooling plate inside the welding chamber are supported by the fixed plate to prevent the support table from lifting the universal wheels and affecting the positioning of automotive parts, so as to meet the positioning accuracy. By providing the support table and a guiding groove is opened on one side of the support table, the process of inserting the limit cover onto the fixed plate is supported.

N-shaped limiting covers 12 are respectively movably sleeved on the two fixed plates 8. A positioning hole 13 is formed on the limiting cover 12. The positioning hole 13 is movably sleeved on the positioning bolt 9. A tooling plate 14 is arranged above the limiting cover 12. The aperture of the positioning hole 13 and the aperture of the sleeve hole 10 are both in line with the diameter of the positioning bolt 9. By first buckling the limiting cover 12 on the fixed plate 8 and then pushing and pulling the limiting cover 12 to slide on the fixed plate 8, the positioning bolt 9 is sleeved in the positioning hole 13, so as to support and position the limiting cover 12 by means of the fixed plate 8 and the positioning bolt 9, quickly position the tooling plate 14 on the support plate 7, and then facilitate using the driving member to drive the welding torch 4 to weld the automobile parts clamped on the tooling plate 14. A plurality of clamps are arranged on the tooling plate 14. The automobile parts are fixed to the tooling plate 14 by the clamps. Since the tooling plate 14 and the limiting cover 12 are detachably assembled with the fixed plate 8, by first assembling the automobile parts onto the tooling plate 14 and then assembling the tooling plate 14 onto the fixed plate 8, the positioning and clamping operations of the automobile parts are quickly completed, thereby reducing the workload of positioning and clamping the automobile parts around the welding device, and further reducing the influence of the positioning and clamping operations on the production speed of the welding process of the automobile parts. The steering mechanism includes a bracket 15 arranged on the welding platform 1 and a motor 16 arranged on the bracket 15. The driving shaft of the motor 16 is connected to the support plate 7, so that the support plate 7 rotates in the sleeve groove 5, enabling the staff to install and repair the automobile parts without entering the welding chamber 2, so as to reduce the harm to the staff. Moreover, the two positioning mechanisms are isolated by the baffle 6, so that the positioning mechanism on one side of the baffle 6 is located inside the welding chamber 2, and the positioning mechanism on the other side of the baffle 6 is located outside the welding chamber 2. The driving member 3 drives the welding torch 4 to weld the automobile parts clamped on the positioning mechanism inside the welding chamber 2. At the same time, it is convenient for the worker to load and unload the automobile parts clamped on the positioning mechanism outside the welding chamber 2, that is, unload the welded automobile parts and replace them with the automobile parts to be welded, so as to separate the loading and unloading operations from the welding operations, so as to facilitate the simultaneous carrying out of the loading and unloading operations and the welding operations.The length of the tooling plate 14, the width of the tooling plate 15, the length of the support plate 7, and the width of the support plate 7 are all not greater than the slot length of the socket groove 5, so as to prevent the tooling plate 14 or the support plate 7 from colliding with the welding chamber 2.

[0024] Please refer to again Figure 6 , the fixing plate 8 adopts a T-shaped structure, and the inner cavity shape of the limit cover 12 matches the outer shape of the fixing plate 8, so as to strengthen the restriction of the fixing plate 8 on the limit cover 12, reduce the shaking of the limit cover 12 during welding, and improve the stability of the welding operation; Please refer to again Figure 7 , a guiding cover 17 is provided on one side of the limit cover 12. The cross-sectional shape of the guiding cover 17 and the end close to the limit cover 12 matches the cross-sectional shape of the limit cover 12. The inner cavity of the guiding cover 17 is connected to the inner cavity of the limit cover 12. The inner diameter of the guiding cover 17 gradually increases along the direction away from the limit cover 12 to facilitate guiding the fixing plate 8 to be inserted into the limit cover 12.

[0025] In this embodiment, two moving components are provided below the tooling plate 14. The two moving components are respectively installed on both sides of the tooling plate 14. The moving component includes a moving frame 18 and two universal wheels 19. The tops of the two universal wheels 19 are respectively installed on both sides of the bottom surface of the moving frame 18, and the top of the moving frame 18 is installed on the bottom surface of the tooling plate 14, so as to convey the tooling plate 14 and the automotive parts clamped on the tooling plate 14 by means of the universal wheels 19. The moving frame 18 is located outside the bracket 15 to prevent the moving frame 18 from colliding with the bracket 15 during rotation.

[0026] Specifically, a positioning groove 20 is opened on the welding platform 1. The positioning groove 20 is communicated with the socket groove 5. A support table 21 is provided outside the positioning groove 20. Both sides of the support table 21 are in contact with the groove walls of the positioning groove 20. The support table 21 is installed on the welding platform 1. A guiding groove 22 is obliquely opened on the side of the support table 21 away from the positioning groove 20. The top groove width of the guiding groove 22 is not less than the bottom groove width of the guiding groove 22, so that the universal wheel 19 can be pushed onto the support table 21 by means of the guiding groove 22 to facilitate inserting the limit cover 12 over the fixing plate 8; when the motor 16 drives the support plate 7 and the positioning mechanism to rotate, after the universal wheel 19 moves into the welding chamber 2, the universal wheel 19 disengages from the top surface of the support table 21, so that the universal wheel 19 is suspended above the positioning groove 20, and the limit cover 12 and the tooling plate 14 in the welding chamber 2 are supported by the fixing plate 8 to meet the accuracy of positioning.

[0027] Please refer to againFigure 2 A handle 23 is provided on the tooling plate 14. The handle 23 adopts an n-shaped rod structure. The bottom end of the handle 23 is installed on the tooling plate 14. By pulling the handle 23, it is convenient to pull the tooling plate 14 for movement.

[0028] In this embodiment, the socket 5 is opened at the bottom of the welding chamber 2. A sealing strip 24 is provided in the socket 5. The sealing strip 24 adopts an n-shaped strip structure made of an elastic material. The sealing strip 24 is installed in the socket 5. The baffle 6 is press-fitted in the sealing strip 24, so as to prevent welding fumes, welding slag, and protective inert gases such as argon used during welding from leaking out through the gap between the welding chamber 2 and the baffle 6, thereby improving the isolation effect of the welding area.

[0029] It should be noted that reinforcing plates 25 are respectively provided on both sides of the baffle 6. The reinforcing plates 25 adopt an L-shaped plate structure. Both sides of the reinforcing plates 25 are respectively installed on the baffle 6 and the support plate 7, so as to reinforce the baffle 6. Please refer to again Figure 5 The motor 16 is installed on the bracket 15. A through hole 26 is opened at the top of the bracket 15. The drive shaft of the motor 16 is sleeved in the through hole 26 to use the motor 16 to support the support plate 7. Further, a bearing is roll-sleeved on the drive shaft of the motor 16. The outer ring and the inner ring of the bearing are respectively installed on the bracket 15 and the support plate 7. The center line of the bearing and the center line of the drive shaft of the motor 16 are located on the same axis to assist the motor 16 in supporting the support plate 7 and improve the reliability of the support of the support plate 7.

[0030] The usage method of this product is as follows: As Figures 1 to 7As shown in the figure, first, according to the positioning requirements of the tooling plate 14 and the automotive components, the automotive components to be welded are sequentially positioned and placed on the tooling plate 14, and then the placed automotive components are clamped on the tooling plate 14 by means of the clamps provided on the tooling plate 14, thus completing the preliminary positioning and clamping operations of the automotive components; Next, by holding the handle 23 and relying on the rolling of the universal wheels 19, the tooling plate 14 is moved to the support table 21 through the guide groove 22, so that the guide cover 17 and the limit cover 12 are sequentially inserted over the fixed plate 8 until the positioning bolt 9 is sleeved in the positioning hole 13, thus completing the positioning and assembly operation of the limit cover 12 and the working plate 14; Then, by operating the motor 16, the support plate 7 is driven to rotate, thereby driving the baffle 6, the two positioning mechanisms, the tooling plate 14 mounted on the positioning mechanisms, and the automotive components clamped on the tooling plate 14 to rotate, so that the automotive components to be welded are moved into the welding chamber 2, and then the driving member 3 is used to weld the automotive components to be welded; At the same time, the above-mentioned preliminary positioning and clamping operations of the automotive components and the positioning and assembly operation of the limit cover 12 and the working plate 14 are repeated, so that the tooling plate 14 carrying the automotive components is assembled on the positioning mechanism outside the welding chamber 2. Then, after the welding operation is completed, the motor 16 is used again to drive the support plate 7 to rotate, so that the two positioning mechanisms change positions, and the automotive components entering the welding chamber 2 are welded; The automotive components and the tooling plate 14 removed from the welding chamber 2 are removed from the fixed plate 8, and then the above-mentioned preliminary positioning and clamping operations of the automotive components and the positioning and assembly operation of the limit cover 12 and the working plate 14 are repeated to continuously carry out the welding operation of the automotive components.

[0031] In addition, it should be noted that in order to position the guide cover 17 with the positioning bolt 9, it is necessary to control the top of the positioning bolt 9 to penetrate out of the sleeve hole 10. Based on this, the positioning bolt 9 needs to rely on the elastic force of the spring 11 to keep the top of the positioning bolt 9 penetrating out of the sleeve hole 10. However, during the process of the guide cover 17 and the limit cover 12 being sequentially inserted over the fixed plate 8, the top of the positioning bolt 9 will block the movement of the guide cover 17 and the limit cover 12, thus affecting the movement of the guide cover 17 and the limit cover 12; To solve this problem, when the guide cover 17 and the limit cover 12 are blocked by the top of the positioning bolt 9, by pulling down the positioning bolt 9, the top of the positioning bolt 9 is inserted into the sleeve hole 10, and the blockage of the guide cover 17 and the limit cover 12 can be eliminated, so as to facilitate the movement of the guide cover 17 and the limit cover 12 on the fixed plate 8. Similarly, during the process of removing the limit cover 12 from the fixed plate 8, since the positioning bolt 9 will block the movement of the limit cover 12, it is necessary to pull down the positioning bolt 9 first before moving the limit cover 12, so that the top of the positioning bolt 9 is inserted into the sleeve hole 10, so as to facilitate the movement of the guide cover 17 and the limit cover 12 on the fixed plate 8.

[0032] Through the embodiments, by means of the provided welding chamber 2, the welding platform 1 is made into a separate space to reduce the harm to workers caused by inert protective gases such as argon, welding fumes and welding slag. And through the provided fixing plate 8, positioning bolts 9 and springs 11, the limiting cover 12 is supported and positioned, so that the tooling plate 14 can be quickly positioned on one side of the support plate 7, thereby improving the positioning efficiency of automotive parts and further increasing the production speed of the welding process. Moreover, in this embodiment, by means of the provided baffle 6, the two positioning mechanisms are separated, so that the positioning mechanism on one side of the baffle 6 is located inside the welding chamber 2, and the positioning mechanism on the other side of the baffle 6 is located outside the welding chamber 2, thus separating the loading and unloading operations from the welding operation to facilitate the simultaneous carrying out of the loading and unloading operations and the welding operation. And through the provided bracket 15 and motor 16, the support plate 7 is driven to rotate in the sleeve groove 5, thereby driving the two positioning mechanisms to switch positions, so that the workers do not need to enter the welding chamber 2 when installing and decorating automotive parts, and further reducing the harm to the workers.

[0033] The above-described embodiments are only the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Therefore, all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent shall be included in the scope of the present invention's patent application.
