Description

Technical Field

[0001] This utility model belongs to the field of sheet metal welding technology, specifically relating to a high-precision sheet metal assembly welding equipment. Background Technology

[0002] Sheet metal parts are products manufactured using sheet metal processing techniques. They are indispensable in our daily lives. Sheet metal parts are made through processes such as filament power winding, laser cutting, heavy-duty machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, die forging, and water jet cutting. They are widely used in electronics, communications, automotive, and medical device industries. A search reveals that application number "CN202420109839.8" discloses "a high-precision sheet metal assembly welding equipment," which describes "placing two sets of sheet metal parts on two sets of inclined surfaces respectively..." By adjusting the height of the support rod, the height of the welding ends of the two sets of sheet metal parts is controlled, allowing the sheet metal parts to contact each other and thus achieving right-angle welding. This solves the problem of inconvenient right-angle welding of sheet metal parts mentioned in the background art. By placing the two sets of sheet metal parts on two inclined planes and adjusting the height of the support rod, the height of the welding ends of the two sets of sheet metal parts is controlled, ensuring that the welding ends of the sheet metal parts contact each other and achieving right-angle welding. This solves the problem of inconvenient right-angle welding of sheet metal parts mentioned in the background art. However, the above comparative documents still have the following problems in actual use:

[0003] In actual use, the angle is not adjustable, which means that only right-angle welding can be performed, resulting in poor versatility. Furthermore, it is impossible to collect the fumes and debris generated during welding, causing them to drift and scatter everywhere, making cleaning troublesome.

[0004] Therefore, providing a device that can achieve adjustable angle and collect welding fumes and debris is highly practical. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example

[0027] Please see Figure 1-4 A high-precision sheet metal assembly welding equipment includes a protective box 100, an adjustment component 200, and a debris and flue gas collection component 300.

[0028] Please refer to the details. Figure 1 An angle sensor is installed at one end of the inner wall of the protective box 100. A first electric cylinder 110 is installed on both sides of the protective box 100. The output shaft ends of the two first electric cylinders 110 are fixedly connected to the fixed plate 120 through the protective box 100.

[0029] Please see Figure 3-4The adjustment assembly 200 includes several hinge seats 210 disposed on one side of the fixed plate 120. Each hinge seat 210 is hinged to a connecting rod 220 on one side. Each connecting rod 220 is provided with a connecting plate 230 on one side. Several fixing pieces 240 are disposed in the middle of one side of the fixed plate 120. Two limiting rods 250 are disposed in the middle of the fixing pieces 240. A moving rod 260 is slidably connected to the outer wall of the two limiting rods 250. Two first connecting seats 270 are disposed on one side of the moving rod 260. An auxiliary rod 280 is hinged to the inside of each of the two first connecting seats 270. A second connecting seat 290 is hinged to the end of each of the two auxiliary rods 280. Two electro-hydraulic rods 2910 are disposed on the top of the moving rod 260.

[0030] In one specific embodiment, the provided electro-hydraulic rods 2910 facilitate clamping the workpiece to be welded by the clamping plate 700. At this time, the controller opens two electro-hydraulic rods 2910, which unfold and push the moving rod 260 to move on the limiting rod 250. The moving rod 260 then drives the two first connecting seats 270 to move. The movement of the first connecting seats 270 pushes the second connecting seat 290 through the auxiliary rod 280, causing the second connecting seat 290 to push the connecting plate 230. The connecting plate 230 unfolds through the hinge seat 210, changing its angle. This causes the clamped workpiece to adjust its angle. The angle sensor detects the workpiece angle in real time. When the predetermined angle is reached, the information is fed back to the controller, causing the controller to close the electro-hydraulic rods 2910 and limit their movement. This achieves the purpose of multi-angle adjustment welding of the two clamped workpieces.

[0031] Please see Figure 2 The debris and flue gas collection assembly 300 includes a connecting hopper 310 sealed and connected to the top of the protective box 100.

The user needs to connect the external connector to an external filter device to filter the generated gas before discharge to avoid environmental pollution. The debris generated during welding will fall into the discharge hopper 350, and be discharged into the collection box 370 through the connecting frame 360 ​​for collection. It can be easily pulled out and cleaned later by the connecting handle, thereby achieving the purpose of collecting debris and fumes.

[0033] Please see Figure 3 One side of each of the two second connecting seats 290 is fixedly connected to the connecting plate 230. The outer walls of the two electric hydraulic rods 2910 are provided with several reinforcing blocks 400, and one side of each of the several reinforcing blocks 400 is fixedly connected to the fixing plate 120.

[0034] In one specific embodiment, the reinforcement block 400 facilitates the support and fixation of the electric hydraulic rod 2910 during use, making the electric hydraulic rod 2910 more stable during use and preventing shaking.

[0035] Please see Figure 2 Two reinforcing plates 500 are provided on one side of the connecting plate 230. A second electric cylinder 600 is provided on the top of one of the reinforcing plates 500. A clamping plate 700 is provided through the end of the second electric cylinder 600 through one of the reinforcing plates 500.

[0036] In one specific embodiment, the clamping plate 700 allows the user to place the workpiece on another reinforcing plate 500, so that the second electric cylinder 600 drives the clamping plate 700 to clamp the workpiece, and the first electric cylinder 110 drives the two workpieces to move, thereby aligning the two workpieces for welding.

[0037] Please see Figure 2 A support block is provided on one side of the inner wall of the protective box 100, and a robotic arm 800 is provided on one side of the support block. A welding head 900 is provided at the end of the robotic arm 800.

[0038] In one specific embodiment, a robotic arm 800 is provided, which allows the controller to open the robotic arm 800 and the welding head 900 during use, and then weld the workpieces together.

[0039] Please see Figure 1The bottom of the protective box 100 is provided with a base 1000, and the bottom of the base 1000 is provided with two support legs 1100. The base 1000 is interlocked with the discharge hopper 350, and the middle of the two support legs 1100 is fixedly connected to the connecting frame 360.

[0040] In one specific embodiment, the provided support leg 1100 facilitates the support and fixation of the top part during use, making the top part more stable during use and preventing wobbling.

[0041] Please see Figure 1 The protective box 100 is hinged to a protective door 1200 at one end, and a handle is provided at one end of the protective door 1200. A door lock is embedded in the inner wall of the handle, and a controller is provided at the top corner of the base 1000.

[0042] In one specific embodiment, the provided handle allows the user to unlock the door lock with a key and open the protective door 1200, enabling the replacement of the workpiece during processing and improving work efficiency.

[0043] Please see Figure 1-4 The angle sensor, the first electric cylinder 110, the electric hydraulic rod 2910, the fan 320, the second electric cylinder 600, the robotic arm 800, and the welding head 900 are all electrically connected to the controller, which is electrically connected to an external power supply.

[0044] In one specific embodiment, a controller is provided to facilitate power supply control of electrical equipment, enabling the equipment to be powered on when needed, thus avoiding situations where power cannot be supplied when power is required.

[0045] In use, the electro-hydraulic rods 2910 are first used to clamp the workpiece to be welded via the clamping plate 700. The controller then activates both electro-hydraulic rods 2910, which unfold and push the moving rod 260 to move on the limit rod 250. The moving rod 260 then moves the two first connecting seats 270. The movement of the first connecting seats 270 pushes the second connecting seat 290 via the auxiliary rod 280. The second connecting seat 290 then pushes the connecting plate 230, causing the connecting plate 230 to unfold via the hinge seat 210, allowing for angle adjustment. This, in turn, adjusts the angle of the clamped workpiece. An angle sensor continuously monitors the workpiece angle, and when the predetermined angle is reached, it feeds back the information to the controller. The controller shuts down the electric hydraulic rod 2910 to limit its position, thereby achieving the purpose of multi-angle adjustment and welding of the two clamped workpieces. Then, the fan 320 is provided to facilitate the intake of the gas generated during the welding process. The gas is drawn into the connecting hopper 310, discharged into the distribution pipe 340 through the conveying pipe 330, and discharged through the external connector. The user needs to connect the external connector to an external filter device to filter the generated gas before discharge to avoid environmental pollution. Finally, the debris generated during welding falls into the discharge hopper 350, passes through the connecting frame 360, and is discharged into the collection box 370 for collection. This allows for easy removal and cleaning via the connecting handle, thus achieving the purpose of collecting debris and fumes.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
