Description

[0001] The invention relates to the technical field of steel springboard welding, in particular to a steel springboard welding device with a welding strength self-inspection function. Background Art

[0002] Steel springboards are widely used in construction projects to modularly construct support panels for construction workers to pass through. In order to ensure structural strength, existing steel springboards often have a reinforcement strip welded on the back of the steel springboard. Therefore, before welding, the reinforcement strip must be positioned and placed.

[0003] However, the reference document (a steel springboard welding device CN218341343U) does not have a self-checking function when welding the steel springboard. It can only be manually inspected by the naked eye to determine whether the welds of the steel springboard meet the standards. In addition, the reference document serves to fix the welded parts, making it easier for the welded parts to be manually welded to the steel springboard. As a result, the welder needs to strictly control the welding quality of the final product.

[0004] The remaining existing steel springboard welding equipment, when in use, can automatically weld the steel springboard, eliminating the need for manual welding, but machine welding will produce a certain number of defective products, and if the finished products are not inspected, defective products will flow out, and when the defective products are put into use, they will cause injuries to users.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example: Figures 1-8As shown, the present invention provides a steel springboard welding device with a welding strength self-inspection function, including a welding equipment body 1 and a distribution box 9, the welding equipment body 1 includes a welding table 11, a support frame 12 is installed on the welding table 11, a welding assembly 2, a limit assembly 3 and a blanking assembly 4 are installed at the bottom of the support frame 12, the blanking assembly 4 cooperates with the welding assembly 2, a pushing assembly 5 is provided on the side of the welding table 11, and multiple groups of conveying tables 13 are provided on the other side of the welding table 11, a limit frame is provided on the conveying table 13, and a detection assembly 6 and a polishing assembly 7 are installed at the bottom of the limit frame, the detection assembly 6 cooperates with the polishing assembly 7, the detection assembly 6 can detect the weld, and the polishing assembly 7 can polish the weld according to the detection assembly 6;

[0031] When the device is in use, when the preliminarily formed steel springboard is transported by the welding table 11, the unloading component 4 of the device will discharge the welding part onto the steel springboard according to the specific position of the photoelectric sensor, and then the limiting component 3 will clamp and limit the welding part to prevent the welding part from positionally shifting during the welding process, so as to prevent the welding part from being unable to effectively support the steel springboard. After the welding of the first welding part is completed, the welding table 11 will continue to transport the steel springboard, and when it reaches another specified position, it will repeat the unloading, limiting and welding. By welding the welding part to the steel springboard, it can support the steel springboard and prevent the steel springboard from bending during use. After the welding of the steel springboard is completed, the pushing component 5 will push the finished steel springboard from the welding table 11 to the conveying table 13, and then the material will be transported through the conveying table 13;

[0032] When the welded steel springboard moves on the conveyor 13, when it reaches the specified position, the conveyor 13 will be paused to stop the steel springboard at a specific position. Then the detection component 6 will detect the weld to determine whether the strength of the weld meets the requirements. Because the device adopts automatic welding by machine during welding, there will definitely be a small amount of defective products during welding, so it is particularly important to perform strength testing on the welded product. The defective products will be marked for subsequent repair welding, and the finished product will pass through the polishing component 7. When the polishing component 7 is used, the weld can be polished to make the weld smoother. Then, when the device is in use, it can automatically weld the semi-finished steel springboard, and can strictly control the welding position when welding the steel springboard to prevent the welded parts from offsetting during the welding process. At the same time, after completing the welding, the weld can also be strength tested to determine the quality of the welding, and then the weld can be polished to make the finished product more beautiful.

[0033] like Figure 2 and Figure 4As shown, in this embodiment, specifically, the blanking assembly 4 includes a blanking frame 41, and cross-limiting pieces 42 are respectively provided on both sides of the blanking frame 41. The cross-limiting pieces 42 are connected to the blanking frame 41 through bearings. Two groups of blanking motors 43 and multiple groups of slave gears 44 are installed on the outside of the blanking frame 41. A main gear 431 is installed at the output end of the blanking motor 43. A chain is installed between the main gear 431 and the multiple groups of slave gears 44. Materials are limited between the two groups of parallel cross-limiting pieces 42, and the multiple groups of slave gears 44 are respectively connected to the cross-limiting pieces 42;

[0034] When the feeding motor 43 drives the main gear 431 to rotate, it will drive the chain to rotate, and the chain is also connected to multiple groups of slave gears 44 at the same time. When the main gear 431 rotates, it will indirectly drive multiple groups of slave gears 44 to rotate. Because each group of slave gears 44 is respectively connected to each group of cross limit plates 42, when the slave gears 44 rotate, it will drive the cross limit plates 42 to rotate together. Because the welding parts are stored between the two cross limit plates 42 on the same horizontal plane, every time the cross limit plate 42 rotates 90° under the rotation of the feeding motor 43, the welding parts will move to the next group of cross limit plates 42, and the welding parts at the bottom will fall onto the steel springboard, so that the device can realize the function of feeding.

[0035] like Figure 2 and Figure 5 As shown, in this embodiment, specifically, the welding assembly 2 includes a support rod 21, a plurality of limit frames 22 are installed at the other end of the support rod 21, a welding gun 23 is installed between the limit frames 22, an adjustment motor 24 is installed on the side of the limit frame 22, and the adjustment motor 24 can adjust the output angle of the welding gun 23, and a plurality of visual sensors are installed at the bottom of the support rod 21, and the visual sensors cooperate with the welding gun 23;

[0036] When in use, the welding component 2 of the device can weld the welding parts and the steel springboard, so that the welding parts can be integrated with the steel springboard, and the steel springboard is supported by the welding parts. In specific use, after the welding parts are limited by the limiting component 3, because the welding position is fixed, the welding component 2 can be combined with the visual sensor and the staff according to the program to weld the welding points more accurately. At the same time, the limiting component 3 can prevent the welding parts from tilting during welding, resulting in uneven support.

[0037] like Figure 2 and Figure 6As shown, in this embodiment, specifically, the limiting assembly 3 includes a limiting cylinder 31 and a correction motor 32. The fixed end of the limiting cylinder 31 is installed at the bottom of the support frame 12. The output end of the limiting cylinder 31 is installed with the correction motor 32. The output end of the correction motor 32 is installed with a correction block 33. Multiple groups of pawls 34 are installed at both ends of the correction block 33. The multiple groups of pawls 34 are respectively connected to the correction block 33 through bearings. Multiple groups of clamping motors 35 are installed on the side of the correction block 33, and the clamping motors 35 are connected to the pawls 34.

[0038] When in use, the limit component 3 of the device can clamp and limit the weldment, and also has a correction function, which can fine-tune and correct the weldment. During specific use, the limit cylinder 31 can push the correction motor 32 to move downward, and at the same time move the correction block 33 downward together, so that the clamping motor 35 can drive the pawl 34, and then the pawl 34 clamps the middle part of the weldment. According to the photoelectric sensor, when a deviation is found in the weldment, the correction motor 32 will drive the correction block 33 to perform fine-tuning together, thereby adjusting the position of the weldment, and then cooperate with the welding component 2 to ensure that the weldment can evenly support the steel springboard.

[0039] like Figure 2 and Figure 7 As shown, in this embodiment, specifically, the detection assembly 6 includes a detection block 61, which is installed at the bottom of the limit frame, and a lifting cylinder is installed above the limit frame. The lifting cylinder is connected to the detection block 61, and a limit groove is provided at the bottom of the detection block 61. A bidirectional screw 62 and multiple groups of limit rods 63 are installed between the limit grooves. A detection motor 64 is installed on the outside of the detection block 61, and the detection motor 64 is connected to the bidirectional screw 62. The bidirectional screw 62 and the multiple groups of limit rods 63 are respectively matched with two groups of limit plates 8, and two groups of limit plates 8 are installed at the bottom of the detection block 61;

[0040] When in use, the detection component 6 of the device can detect the welding point and determine the strength of the welding point. In specific use, when the welded steel springboard is at a specific position on the feeding platform, the lifting cylinder will drive the detection block 61 to move downward. When it moves to the bottom, the detection motor 64 will drive the bidirectional screw 62 to rotate, so that the limit plate 8 moves to both sides of the steel springboard, and then the limit plate 8 moves to the welding point, thereby facilitating the detection of the welding point.

[0041] like Figure 7As shown, in this embodiment, specifically, two groups of downward pressure cylinders 81 and two groups of squeeze cylinders 82 are installed inside the limit plate 8. The downward pressure cylinder 81 is installed in the middle of the limit plate 8, and the squeeze cylinder 82 is installed at the bottom of the limit plate 8. A test block 811 is provided on the limit plate 8, and the test block 811 is connected to the two groups of downward pressure cylinders 81. A squeeze plate 821 is installed at the output end of the squeeze cylinder 82, and the squeeze plate 821 cooperates with the test block 811. A pressure sensing plate is installed on the squeeze plate 821;

[0042] When the limit plate 8 moves to a specific position, the downward pressure cylinder 81 and the squeeze cylinder 82 will work simultaneously. The downward pressure cylinder 81 can drive the test block 811 to move downward to press down the weld, and the squeeze cylinder 82 will drive the squeeze plate 821 to move upward, so that the squeeze plate 821 supports the bottom of the weld. After that, the downward pressure cylinder 81 continuously pressurizes the weld, and the force between the squeeze plate 821 and the test block 811 continues to increase, so that the current pressure value can be accurately obtained according to the pressure sensing plate, which facilitates the determination of the strength test value.

[0043] like Figure 1 As shown, in this embodiment, specifically, the polishing assembly 7 includes a polishing cylinder 71, a polishing motor 72 is installed at the bottom of the polishing cylinder 71, and a polishing wheel 73 is installed at the bottom of the polishing motor 72, and the polishing wheel 73 cooperates with the welding part;

[0044] When in use, the polishing component 7 of the device can polish the welding joint to make the welding joint smoother. In specific use, when the finished steel springboard passes through the polishing component 7, the polishing cylinder 71 will drive the polishing motor 72 to move downward, and then the polishing motor 72 will drive the polishing wheel 73 to rotate, and then the welding joint is polished by the polishing wheel 73.

[0045] like Figure 3 As shown, in this embodiment, specifically, the welding table 11 is provided with multiple sets of rollers, which are driven by a motor, and the conveying table 13 is also provided with multiple sets of rollers, which are also driven by a motor;

[0046] Because the welding table 11 is provided with multiple sets of rollers, and the rollers can be driven by the motor to rotate, so that the semi-finished steel springboard can be moved on the welding table 11, and the conveying table 13 is also provided with rollers, which can also be driven by the motor to rotate. When the steel springboard moves to the welding table 11, the rollers on the welding table 11 will drive the steel springboard to move, thereby transporting the steel springboard.

[0047] like Figure 3As shown, in this embodiment, specifically, the pushing assembly 5 includes multiple groups of pushing cylinders 51, which are connected to the welding table 11. The output end of the pushing cylinder 51 is equipped with a pushing plate 52, which cooperates with the material. The pushing assembly 5 can push the material from the welding table 11 to the conveying table 13;

[0048] When in use, the pushing component 5 of the device can push the finished steel springboard, and can push the welded finished steel springboard onto the conveying platform 13. In specific use, when the steel springboard is welded, the pushing cylinder 51 will push the pushing plate 52, and then the finished steel springboard is pushed by the pushing plate 52, and pushed from the welding table 11 to the conveying table 13, so as to facilitate the subsequent process of the welded steel springboard.

[0049] like Figure 1 As shown, in this embodiment, specifically, a distribution box 9 is installed on the side of the welding equipment body 1, the welding equipment body 1 is connected to the distribution box 9, and a control platform is provided on the distribution box 9;

[0050] When the device is in use, the entire welding equipment body 1 can be controlled through the power distribution cabinet, and because a control panel is provided on the distribution box 9, the staff can indirectly control the welding equipment body 1 through the control panel.

[0051] Working principle: When the device is in use, when the preliminarily formed steel springboard is transported through the welding table 11, the unloading component 4 of the device will discharge the welding parts onto the steel springboard at a specific position according to the photoelectric sensor, and then the limiting component 3 will clamp and limit the welding parts to prevent the welding parts from positionally shifting during the welding process, and prevent the welding parts from being unable to effectively support the steel springboard. After the welding of the first welding part is completed, the welding table 11 will continue to transport the steel springboard, and when it reaches another specified position, it will repeat unloading, limiting and welding. By welding the welding parts to the steel springboard, it can support the steel springboard and prevent the steel springboard from bending during use. After the welding of the steel springboard is completed, the pushing component 5 will push the finished steel springboard from the welding table 11 to the conveying table 13, and then the material will be transferred through the conveying table 13;

[0052] When the welded steel springboard moves on the conveyor 13, when it reaches the specified position, the conveyor 13 will be paused to stop the steel springboard at a specific position. Then the detection component 6 will detect the weld to determine whether the strength of the weld meets the requirements. Because the device uses automatic welding of the machine during welding, there will definitely be a small amount of defective products during welding, so it is particularly important to perform strength testing on the welded product. The defective products will be marked for subsequent repair welding, and the finished product will pass through the polishing component 7. When the polishing component 7 is used, the weld can be polished to make the weld smoother. Then, when the device is in use, it can automatically weld the semi-finished steel springboard, and can strictly control the welding position when welding the steel springboard to prevent the weld from offsetting during the welding process. At the same time, after completing the welding, the weld can also be strength tested to determine the quality of the welding, and then the weld can be polished to make the finished product more beautiful.

[0053] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
