Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding device for car door welded parts with a cooling effect. Background Technology

[0002] During automobile production, car doors require welding. Similarly, damaged doors also need to be welded. During welding, clamps are used to hold and secure the door, preventing it from shifting and affecting weld quality. However, traditional welding clamps are mostly limited to clamping doors of fixed sizes, resulting in low applicability. Furthermore, the welding process generates significant heat, causing the door temperature to rise, which could easily lead to burns if someone accidentally touches it.

[0003] To address the aforementioned issues, a search revealed, for example, a high-precision automotive right door welding fixture assembly with heat insulation function, provided by patent publication number CN217452758U. This assembly includes a base, with a support rod symmetrically fixed to the front top of the base. A support is hinged to the top of the support rod. A cylinder is symmetrically embedded in the rear top of the base. Vertical plates are symmetrically slidably mounted on the top of the support. Horizontal plates are slidably mounted on adjacent sides of the vertical plates. Support rods are arrayed and fixed on adjacent sides of the horizontal plates. Pressure blocks are hinged to the other ends of the support rods. Anti-slip pads are fixed to the bottom ends of the pressure blocks. Cavities are arrayed on adjacent sides of the horizontal plates. Cavities are hinged to the inner walls of the cavities near the vertical plates. This assembly facilitates clamping and fixing of automotive doors of different specifications, effectively improving the applicability of the fixture and simultaneously providing effective cooling for the workpiece.

[0004] Based on the above search and analysis of existing technologies, it has been found that the cooling structures of existing welding devices similar to those disclosed above are merely simple platforms. However, the surface of a car door is not planar, resulting in a relatively small contact area between the door and the platform, making it difficult to guarantee effective cooling during welding. Furthermore, since different car door models have different shapes and sizes, a cooling platform of a single shape cannot achieve effective cooling. Therefore, a welding device for car door welded parts with a cooling effect is proposed to improve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a welding device for car door welded parts with a cooling effect, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a welding device for car door welded parts with cooling effect, including a frame, a welding head and a clamping mechanism, wherein an adjustment device connected to the welding head is installed at the inner top of the frame, and the clamping mechanism includes clamping components respectively installed at the upper and lower ends of both sides of the frame.

[0007] A cooling mechanism is provided at the bottom inner end of the rack. The cooling mechanism includes a cooling cavity located inside the rack, multiple cooling components arranged in an array at the bottom inner end of the rack and extending vertically to the inside of the cooling cavity, and a water tank installed at the bottom of the rack.

[0008] The bottom of the frame is provided with a through hole for connecting the cooling chamber and the water storage tank. A circulating refrigeration device is installed at the bottom of the water storage tank. The input and output ends of the circulating refrigeration device are fixedly connected to the opposite sides of the cooling chamber through circulating pipes. A piston plate is vertically slidably installed on the inner side of the water storage tank. A lifting drive device II connected to the piston plate is installed at the bottom of the water storage tank to drive the piston plate to move up and down.

[0009] As a further supplement to this solution, the cooling components include a sliding column, a limiting stop column, and a limiting plate;

[0010] The sliding column is vertically slidably installed at the inner bottom of the frame. The lower end of the sliding column is fixed to the limiting abutment, and the diameter of the limiting plate is larger than the diameter of the sliding column.

[0011] As a further supplement to this solution, the cooling component also includes a tension spring, which is fixed between the bottom end of the limiting plate and the inner bottom end of the cooling chamber.

[0012] As a further supplement to this solution, the cooling component also includes a spherical connecting block and a heat-conducting plate;

[0013] The spherical connecting block is movably installed on the top of the sliding column, and the heat-conducting plate is fixed on the spherical connecting block.

[0014] As a further supplement to this solution, the clamping assembly includes a clamping block and a lifting drive device 1, which is fixed on the frame and the output end of the lifting drive device 1 is fixed to the clamping block.

[0015] As a further supplement to this solution, the clamping assembly also includes multiple adjusting screws, which are equidistantly distributed along the length of the clamping block and have vertical threads penetrating the clamping block.

[0016] In summary, the technical effects and advantages of this utility model are as follows:

[0017] 1. In this utility model, through the coordinated arrangement of a water storage tank, a circulating cooling device, and multiple cooling components, after the car door is fixed by the clamping mechanism, the piston plate is driven to move up by the lifting drive device, squeezing the cooling water in the water storage tank into the cooling chamber through the through hole. The sliding column moves up under the pressure of the water until it contacts the car door. The heat-conducting material of the sliding column can effectively achieve heat exchange with the car door, resulting in a good cooling effect. Compared with the existing single platform contact cooling, the cooling effect of multiple sliding columns in this solution contacting the car door for heat transfer is better.

[0018] 2. In this utility model, by setting up the spherical connecting block and the heat-conducting plate, the heat-conducting plate can be flexibly deflected under the action of the spherical connecting block and the sliding column, so that it can fit better with the car door. Compared with the sliding column, the contact area between the heat-conducting plate and the car door is larger, and the cooling effect is better.

[0019] 3. In this utility model, by distributing multiple adjusting screws at equal intervals along the length of the clamping block and vertically threading them through the clamping block, after the clamping block clamps the car door, the operator can manually turn the corresponding adjusting screw according to the actual shape of the car door, so that the adjusting screw abuts against the car door, thus better clamping the car door.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: Reference Figure 1-5 The welding device for car door welded parts with cooling effect shown includes a frame 1, a welding head 3 and a clamping mechanism. An adjustment device 2 connected to the welding head 3 is installed at the inner top of the frame 1. The clamping mechanism includes clamping components 4 installed at the upper and lower ends of both sides of the frame 1.

[0029] The clamping assembly 4 includes a clamping block 41 and a lifting drive device 42. The lifting drive device 42 is fixed on the frame 1. The output end of the lifting drive device 42 is fixed to the clamping block 41. The lifting drive device 42 drives the clamping block 41 to rise and fall, and the two corresponding clamping blocks 41 are used to clamp and fix the car door.

[0030] Considering the different shapes of car doors, in order to stably clamp the car door, the clamping assembly 4 also includes multiple adjusting screws 43. The multiple adjusting screws 43 are evenly distributed along the length direction of the clamping block 41 and vertically threaded through the clamping block 41. After the car door is clamped by the clamping block 41, the operator can manually turn the corresponding adjusting screw 43 according to the actual shape of the car door so that the adjusting screw 43 abuts against the car door, thus better clamping the car door. In order to avoid hard pressure damage to the car door, a rubber pad can be added to the end of the adjusting screw 43 that contacts the car door.

[0031] The frame 1 has a cooling mechanism at its inner bottom. The cooling mechanism includes a cooling chamber 101 located inside the frame 1, multiple cooling components 6 arranged in an array at the inner bottom of the frame 1 and extending vertically to the inner side of the cooling chamber 101, and a water tank 5 installed at the bottom of the frame 1. The bottom of the frame 1 has a through hole for connecting the cooling chamber 101 and the water tank 5. The bottom of the water tank 5 has a circulating cooling device 7 installed on its outer bottom. The input and output ends of the circulating cooling device 7 are fixedly connected to the opposite sides of the cooling chamber 101 through circulating pipes. A piston plate 9 is vertically slidably installed inside the water tank 5. The bottom of the water tank 5 has a lifting drive device 8 connected to the piston plate 9 to drive the piston plate 9 to move up and down. The water tank 5 contains cooling water, which is located above the piston plate 9. In addition, it should be noted that in order to ensure that the piston plate 9 can move up and down smoothly, the bottom of the water tank 5 has a balancing vent.

[0032] Among them, the adjustment device 2 adopts conventional electric drive equipment to drive the welding head 3 to move flexibly to achieve welding at different positions of the car door. The lifting drive device 1 42 and the lifting drive device 2 8 can both adopt existing conventional lifting drive equipment, such as hydraulic cylinders and air cylinders. In addition, the circulating refrigeration device 7 is a conventional circulating refrigeration device in the prior art, including components such as a refrigerator and a circulating pump. Furthermore, the adjustment device 2, the lifting drive device 1 42, the lifting drive device 2 8, the refrigerator, the circulating pump, and other electrical components are all electrically connected to the external controller and power supply using conventional technical means.

[0033] Regarding cooling component 6, specifically, as follows: Figure 4 and Figure 5 As shown, the cooling component 6 includes a sliding column 61, a limiting abutment 62, and a limiting plate 63. The sliding column 61 is vertically slidably installed on the inner bottom end of the frame 1. The lower end of the sliding column 61 is fixed to the limiting abutment 62, and the diameter of the limiting plate 63 is larger than the diameter of the sliding column 61.

[0034] Based on the above-mentioned arrangement of water tank 5, circulating cooling device 7 and multiple cooling components 6, after the car door is fixed by the clamping mechanism, the piston plate 9 is driven to move upward by the lifting drive device 8, which squeezes the cooling water in the water tank 5 into the cooling chamber 101 through the through hole. The sliding column 61 moves upward under the pressure of the water until it contacts the car door. The sliding column 61 is made of thermally conductive material, which can effectively realize the heat exchange between the sliding column 61 and the car door, and achieve a good cooling effect. Compared with the existing single platform contact cooling, the cooling effect of multiple sliding columns 61 contacting the car door for heat transfer in this solution is better.

[0035] In order to prevent water from seeping out from the gap between the slide column 61 and the frame 1, a conventional sealing ring structure (not shown in the figure) can be installed at the bottom of the slide column 61.

[0036] The cooling component 6 also includes a tension spring 64, which is fixed between the bottom end of the limiting plate 63 and the inner bottom end of the cooling chamber 101. After use, the piston plate 9 is driven to move down by the lifting drive device 8, and the cooling water in the cooling chamber 101 flows back to the water storage tank 5 through the through hole. The sliding column 61 can smoothly return to its original position under its own weight and the action of the tension spring 64, thus preventing the sliding column 61 from being continuously exposed to the outside environment and being scratched.

[0037] To further improve the cooling effect, the cooling component 6 also includes a spherical connecting block 65 and a heat-conducting plate 66. The spherical connecting block 65 is movably installed on the top of the sliding column 61, and the heat-conducting plate 66 is fixed on the spherical connecting block 65. Under the action of the movable connection between the spherical connecting block 65 and the sliding column 61, the heat-conducting plate 66 can be flexibly deflected, so as to better fit with the car door. Compared with the sliding column 61, the heat-conducting plate 66 has a larger contact area with the car door, resulting in a better cooling effect.

[0038] In addition, although the spherical connecting block 65 and the sliding column 61 are connected in a movable manner, which will reduce the heat transfer effect to some extent, the heat-conducting plate 66 increases the contact area with the car door. Its effect on enhancing heat dissipation is obviously greater than its effect on reducing heat transfer. Therefore, overall, the added spherical connecting block 65 and heat-conducting plate 66 have a positive effect on cooling the car door.

[0039] The working principle of this utility model is as follows: The lifting drive device 42 drives the clamping block 41 to rise and fall. The two corresponding clamping blocks 41 are used to clamp and fix the car door. After the car door is clamped by the clamping block 41, the operator can manually turn the corresponding adjusting screw 43 according to the actual shape of the car door so that the adjusting screw 43 abuts against the car door and clamps the car door better.

[0040] After the car door is fixed in place by the clamping mechanism, the piston plate 9 is driven to move upward by the lifting drive device 28, which squeezes the cooling water in the water tank 5 into the cooling chamber 101 through the through hole. The sliding column 61 moves upward under the pressure of the water, and the heat conduction plate 66 can be flexibly deflected under the action of the spherical connecting block 65 and the sliding column 61, so that it can fit better with the car door, increase the contact area between the door and the door, and achieve better cooling effect.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
