Description

Technical Field

[0001] This utility model belongs to the technical field of welding auxiliary equipment, specifically an adjustable stainless steel baffle bracket for welding. Background Technology

[0002] During welding operations, welding spatter (such as molten slag and sparks) can easily damage operators and surrounding equipment. Therefore, it is necessary to install baffles to protect the welding area. Stainless steel baffles are widely used in the field of welding protection due to their excellent high temperature resistance and corrosion resistance.

[0003] However, existing stainless steel baffle supports for welding have many shortcomings: First, the angle adjustment is limited. Most supports are fixed angle or manually adjusted by bolts, with a small adjustment range and low precision. This makes it difficult to adapt to complex working conditions such as multi-angle welding and welding in special postures, resulting in poor matching between the protected area and the welding area, and easy escape of spatter. Second, the protected area is fixed. When facing workpieces of different sizes, if the workpiece is larger than the baffle area, blind spots are likely to occur. If the workpiece is much smaller than the baffle area, it will cause space waste. Moreover, replacing the baffle requires stopping the machine, increasing labor costs.

[0004] Therefore, an adjustable stainless steel baffle bracket for welding is proposed to address the above issues. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides an adjustable stainless steel baffle bracket for welding, which has the advantages of precise and flexible angle adjustment and dynamic adaptation of the protected area.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable angle bracket for welding stainless steel baffles, including a base plate, a tilt angle adjustment component mounted on the base plate, a U-shaped bracket connected to the tilt angle adjustment component, a cylinder mounted on the U-shaped bracket, a piston rod of the cylinder connected to the U-shaped bracket, an angle adjustment drive component mounted on the U-shaped bracket, a baffle connected to the angle adjustment drive component, and an area expansion component mounted on the baffle.

[0007] Preferably, a fixing lug is fixedly connected to the base plate, and a fixing hole is provided on the fixing lug.

[0008] Preferably, the tilt angle adjustment assembly includes two symmetrically arranged first rotating shafts connected to the bottom end of the U-shaped bracket. The first rotating shafts are mounted on the base plate. A horizontal plate is fixedly connected to the rear side of the U-shaped bracket. A second rotating shaft is mounted on the horizontal plate. The second rotating shaft is connected to an electric telescopic rod. A third rotating shaft is connected to the end of the electric telescopic rod. The third rotating shaft is mounted on the base plate.

[0009] Preferably, a positioning groove is provided on the inner wall of the U-shaped bracket, and the positioning groove is slidably connected to the U-shaped bracket through a positioning slider.

[0010] Preferably, the angle adjustment drive assembly includes a first motor mounted on a U-shaped frame. The output end of the first motor is connected to a drive gear via a motor shaft. The drive gear meshes with a driven gear. The driven gear is fixedly connected to one end of the bottom of the baffle via a rotating rod. The side of the driven gear away from the rotating rod and the other end of the bottom of the baffle are both connected to the U-shaped frame via bearings.

[0011] Preferably, the area expansion component includes a fixing plate disposed on the rear side of the baffle, a second motor is installed at the bottom of the fixing plate, a lead screw is connected to the output end of the second motor, the lead screw passes through the fixing plate, a threaded connecting sleeve is threadedly connected to the lead screw, an L-shaped rod is fixedly connected to the threaded connecting sleeve, and an expansion plate is fixedly connected to the L-shaped rod.

[0012] Preferably, the top of the baffle is provided with a groove, and the bottom end of the extension plate is located in the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model achieves flexible and precise control of the baffle angle through the coordinated operation of the tilt angle adjustment component and the angle adjustment drive component. In the tilt angle adjustment component, the electric telescopic rod drives the U-shaped bracket to rotate around the first rotating shaft through the hinge structure of the second and third rotating shafts, which can quickly adjust the overall tilt angle of the baffle to meet the spatial adaptation requirements of multi-angle welding of workpieces. The angle adjustment drive component relies on the first motor and gear transmission mechanism to drive the baffle to rotate around the rotating rod, so as to achieve fine adjustment of the baffle's own angle. The dual-adjustment design not only expands the angle adjustment range but also improves the adjustment accuracy, so that the protective area can closely fit the welding area, effectively blocking the escape of spatter, while reducing the operation intensity of manual adjustment and adapting to the dynamic protection requirements under complex welding conditions.

[0015] 2. This utility model's area expansion component achieves dynamic adaptation of the protective area through a mechanical transmission structure. The second motor drives the lead screw to rotate, causing the threaded connecting sleeve to move along the lead screw axis. This, in turn, pushes the expansion plate to slide smoothly along the groove on the top of the baffle via the L-shaped rod. This allows the expansion plate to flexibly extend and retract according to the workpiece size. When welding large workpieces, the expansion plate extends outward to expand the protective area and eliminate blind spots. When welding small workpieces, the expansion plate retracts to avoid wasting space. This design, which eliminates the need to stop the machine to replace the baffle, not only saves labor costs but also ensures structural stability in the expanded state through the guidance and support of the plate groove. This allows the baffle to reliably withstand the impact of welding spatter under different area specifications, adapting to the protection needs of diverse welding scenarios.

[0028] 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.

[0029] like Figures 1 to 5As shown, this utility model provides an adjustable stainless steel baffle bracket for welding, including a base plate 1, a tilt angle adjustment component 2 installed on the base plate 1, a U-shaped bracket 3 connected to the tilt angle adjustment component 2, a cylinder 4 installed on the U-shaped bracket 3, a U-shaped frame 5 connected to the piston rod of the cylinder 4, an angle adjustment drive component 6 installed on the U-shaped frame 5, a baffle 7 connected to the angle adjustment drive component 6, and an area expansion component 8 installed on the baffle 7.

[0030] Specifically, a fixing ear 9 is fixedly connected to the base plate 1, and a fixing hole 10 is provided on the fixing ear 9. The base plate 1 can be firmly installed at the welding station through the fixing hole 10 and the bolt, thereby improving the overall stability of the support and avoiding displacement caused by welding vibration.

[0031] Furthermore, the tilt angle adjustment component 2 includes two symmetrically arranged first rotating shafts 201 connected to the bottom end of the U-shaped bracket 3. The first rotating shafts 201 are mounted on the base plate 1. A horizontal plate 202 is fixedly connected to the rear side of the U-shaped bracket 3. A second rotating shaft 203 is mounted on the horizontal plate 202. An electric telescopic rod 204 is connected to the second rotating shaft 203. A third rotating shaft 205 is connected to the end of the electric telescopic rod 204. The third rotating shaft 205 is mounted on the base plate 1. The electric telescopic rod 204 extends and retracts through the hinge structure of the second rotating shaft 203 and the third rotating shaft 205, which can push the U-shaped bracket 3 to rotate around the first rotating shaft 201, quickly adjust the overall tilt angle of the baffle 7, adapt to the spatial requirements of multi-angle welding of workpieces, and improve the matching degree between the protection area and the welding area.

[0032] Furthermore, a positioning groove 11 is provided on the inner wall of the U-shaped bracket 3. The positioning groove 11 is slidably connected to the U-shaped frame 5 through the positioning slider 12. The cooperation between the positioning groove 11 and the positioning slider 12 provides guidance for the up and down movement of the U-shaped frame 5, preventing the cylinder 4 from deviating when pushing the U-shaped frame 5, and improving the stability of the structure operation.

[0033] It is worth noting that the angle adjustment drive assembly 6 includes a first motor 601 mounted on the U-shaped frame 5. The output end of the first motor 601 is connected to a drive gear 602 via a motor shaft. The drive gear 602 is meshed with a driven gear 603. The driven gear 603 is fixedly connected to one end of the bottom of the baffle 7 via a rotating rod 604. The side of the driven gear 603 away from the rotating rod 604 and the other end of the bottom of the baffle 7 are both connected to the U-shaped frame 5 via bearings. The first motor 601 drives the drive gear 602 to rotate, and through gear meshing, drives the driven gear 603 and the rotating rod 604 to rotate, thereby achieving fine adjustment of the angle of the baffle 7 itself, further optimizing the protection angle, and effectively preventing splashes from escaping.

[0034] It is worth noting that the area expansion component 8 includes a fixed plate 801 located behind the baffle 7. A second motor 802 is installed at the bottom of the fixed plate 801. The output end of the second motor 802 is connected to a lead screw 803. The lead screw 803 passes through the fixed plate 801 and is threadedly connected to a threaded connecting sleeve 804. An L-shaped rod 805 is fixedly connected to the threaded connecting sleeve 804. An expansion plate 806 is fixedly connected to the L-shaped rod 805. The second motor 802 drives the lead screw 803 to rotate, causing the threaded connecting sleeve 804 to move axially along the lead screw 803. The L-shaped rod 805 pushes the expansion plate 806 to slide along the plate groove 807, realizing the dynamic expansion or contraction of the protective area. This adapts to the welding protection needs of workpieces of different sizes, eliminating the need to stop the machine to replace the baffle 7 and saving labor costs.

[0035] It is worth mentioning that the top of the baffle 7 is provided with a plate groove 807, and the bottom end of the extension plate 806 is located in the plate groove 807. The plate groove 807 stores and guides the extension plate 806, ensuring the structural stability of the extension plate 806 during the extension and retraction process.

[0036] Among them, the electric telescopic rod 204, cylinder 4, first motor 601, and second motor 802 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail.

[0037] Working principle and process: First, the bracket is fixed as a whole by using bolts through the fixing holes 10 of the fixing ears 9 on the base plate 1. Then, the electric telescopic rod 204 of the tilt angle adjustment component 2 is activated. It extends and retracts through the hinge structure of the second rotating shaft 203 and the third rotating shaft 205, pushing the U-shaped bracket 3 to rotate around the first rotating shaft 201 to adjust the overall tilt angle of the baffle 7. Then, the cylinder 4 is activated, and its piston rod pushes the U-shaped bracket 5 to slide up and down along the positioning slide groove 11 on the inner wall of the U-shaped bracket 3 to adjust the height of the baffle 7. Then, the angle adjustment is activated. The first motor 601 of the adjustment drive assembly 6 drives the drive gear 602 to rotate. Through the meshing transmission with the driven gear 603, the rotating rod 604 drives the baffle 7 to rotate around the bearing connection point to complete the fine angle adjustment. Finally, according to the workpiece size, the second motor 802 of the area expansion assembly 8 is activated. It drives the lead screw 803 to rotate, causing the threaded connecting sleeve 804 to move along the lead screw 803 and drive the expansion plate 806 to extend and retract along the plate groove 807 on the top of the baffle 7 through the L-shaped rod 805, thereby realizing the flexible adjustment of the protection area.
