Description

Technical Field

[0001] This utility model relates to the field of electromechanical support welding technology, and in particular to a positioning welding device for electromechanical installation supports. Background Technology

[0002] In electromechanical installation engineering, various supports and hangers are key components used to fix pipes, cable trays, and equipment. Among them, the T-shaped support is a widely used foundation type, which is usually made by vertically welding a long angle iron as a supporting vertical rod and a short angle iron as a fixing crossarm.

[0003] Currently, the welding of T-shaped brackets in the industry has gradually transitioned from purely manual operation to the use of automatic welding equipment, such as dual-gun welding machines, to improve production efficiency. These devices can achieve automated welding operations.

[0004] However, existing automated equipment still requires manual placement of the long and short angle iron sections during the pre-welding loading and positioning stages, which heavily relies on the operator's experience. The equipment lacks automatic centering and precise clamping functions, resulting in unstable and inconsistent quality of the finished T-shaped brackets. Utility Model Content

[0005] This invention addresses the aforementioned problems by providing a positioning and welding device for electromechanical mounting brackets. The centering, positioning, and clamping operations are fully automated, eliminating human error and fundamentally ensuring the verticality and symmetry of the T-shaped brackets, thus ensuring stable and consistent product quality.

[0006] The technical solution adopted to solve the above technical problems is: a positioning welding device for electromechanical mounting brackets, including a frame, a welding gun, a clamping shoe, a pressure plate and two clamping plates. The welding gun is movably connected to both sides of the upper part of the frame. The clamping shoe is horizontally slidably connected to the upper part of the frame. The clamping shoe is arranged in an "n" shape. The pressure plate is horizontally slidably connected to the upper part of the frame. The clamping shoe and the pressure plate are used to clamp long angle irons. The two clamping plates are horizontally slidably connected to the frame. The two clamping plates are used to clamp short angle irons. The clamped long angle irons are located at the center of the clamped short angle irons.

[0007] Furthermore, it also includes connectors, guide rods, a first spring, pressure blocks, pressure sensors, and a motor. Connectors are slidably connected to both sides of the frame. The clamping plates are slidably connected to the connectors via guide rods. The first spring is sleeved on the guide rod and provides elastic force to the clamping plates. Pressure blocks are fixedly connected to the outside of the clamping plates. Pressure sensors are fixedly connected to the connectors. The pressure blocks cooperate with the pressure sensors. The motor is connected inside the frame, and the pressure sensors are electrically connected to the motor. The movement of the two pressure plates is driven by the motor.

[0008] Furthermore, it also includes a mounting component, a spline sleeve, a spline shaft, a first engaging wheel, a rotating shaft, a second engaging wheel, and a second spring. The mounting component is fixedly connected to the output end of the motor, the spline sleeve is fixedly connected to the mounting component, the spline shaft is splinedly engaged with the spline sleeve, the first engaging wheel is fixedly connected to the end of the spline shaft, the rotating shaft is rotatably connected to the frame, the second engaging wheel is fixedly connected to the end of the rotating shaft, the first engaging wheel and the second engaging wheel can be engaged or disengaged, the second spring is sleeved on the spline shaft, and the second spring pushes the first engaging wheel and the second engaging wheel to engage, and the movement of the chuck and the pressure plate is driven by the rotating shaft.

[0009] Furthermore, it also includes a first gear, a first rack, a second gear, a second rack, and a bevel gear shaft assembly. The first gear is fixedly connected to the end of the rotating shaft. First racks are respectively meshed on both sides of the first gear. The two first racks are respectively fixedly connected to the chuck and the pressure plate. The second gear is rotatably connected to the frame. Second racks are respectively meshed on both sides of the second gear. The two second racks are respectively fixedly connected to the two connecting members. The bevel gear shaft assembly links the motor output shaft with the second gear.

[0010] Furthermore, it also includes a guide plate connected to the side of the clamping plate. The guide plate is used to guide the short angle iron. The clamping plate is L-shaped, and the clamping inlet of the shoe is opened as an inclined surface.

[0011] Furthermore, it also includes a first support, a second support, and a magnet. The first support is fixed to the frame and is used to support the short angle iron. The second support is connected to the upper side of the frame, the long angle iron abuts against the second support, and the magnet is embedded in the second support.

[0012] The beneficial effects of this utility model are as follows: By setting an "n"-shaped clamping shoe and a pressure plate to work together, the "n"-shaped clamping shoe facilitates the side insertion of the long angle iron, ensuring that the long angle iron is automatically constrained within the specific space of the clamping shoe during the clamping process.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] like Figures 1-5 As shown, this embodiment provides a positioning welding device for an electromechanical mounting bracket, including a frame 1, a welding torch 2, a clamping shoe 3, a pressure plate 4, and two clamping plates 5. The welding torch 2 is movably connected to both sides of the upper part of the frame 1. The clamping shoe 3 is horizontally slidably connected to the upper part of the frame 1. The clamping shoe 3 is arranged in an "n" shape. The pressure plate 4 is horizontally slidably connected to the upper part of the frame 1. The clamping shoe 3 and the pressure plate 4 are used to clamp long angle irons. The two clamping plates 5 are horizontally slidably connected to the frame 1. The two clamping plates 5 are used to clamp short angle irons. The clamped long angle iron is located at the center of the clamped short angle iron.

[0021] In the above embodiments, double-gun welding is used to weld the long angle iron and the short angle iron on both sides. The welding gun 2 and its movement mode can be achieved using existing technology, which is clear and will not be described in detail. By setting an "n"-shaped clamping shoe 3 and a pressure plate 4 to work together, the "n"-shaped clamping shoe 3 facilitates the side insertion of the long angle iron and ensures that the long angle iron is automatically constrained within the specific space of the clamping shoe 3 during the clamping process. The short angle iron is clamped by the two pressure plates 4, and the clamped long angle iron is centered and positioned at the center of the clamped short angle iron. The centering and clamping operation is fully automated, eliminating human error and fundamentally ensuring the verticality and symmetry of the T-shaped bracket, so as to make the product quality stable and consistent.

[0022] Specifically, it also includes a connector 6, a guide rod 7, a first spring 8, a pressure block 9, a pressure sensor 10, and a motor 11. The connector 6 is slidably connected to both sides of the frame 1. The clamping plate 5 is slidably connected to the connector 6 through the guide rod 7. The first spring 8 is sleeved on the guide rod 7 and provides elastic force to the clamping plate 5. The pressure block 9 is fixedly connected to the outside of the clamping plate 5. The pressure sensor 10 is fixedly connected to the connector 6. The pressure block 9 cooperates with the pressure sensor 10. The motor 11 is connected inside the frame 1. The pressure sensor 10 is electrically connected to the motor 11. The movement of the two pressure plates 4 is driven by the motor 11.

[0023] In the above embodiments, the clamping plate 5, through the guide rod 7, the first spring 8, and the connecting piece 6, forms a flexible clamping mechanism that can adaptively clamp short angle irons of different lengths. When the two clamping plates 5 come together to clamp the short angle iron, the first spring 8 is compressed. When the clamping force reaches the preset value, the pressure block 9 triggers the pressure sensor 10, and the system automatically controls the motor 11 to stop. This realizes intelligent sensing and control of the clamping force, which not only protects the workpiece from excessive squeezing but also ensures the reliability of clamping and effectively improves the flexibility of the device.

[0024] Specifically, it also includes a mounting component 12, a spline sleeve 13, a spline shaft 14, a first engaging wheel 15, a rotating shaft 16, a second engaging wheel 17, and a second spring 18. The mounting component 12 is fixedly connected to the output end of the motor 11, the spline sleeve 13 is fixedly connected to the mounting component 12, the spline shaft 14 is splinedly engaged with the spline sleeve 13, the first engaging wheel 15 is fixedly connected to the end of the spline shaft 14, the rotating shaft 16 is rotatably connected to the frame 1, the second engaging wheel 17 is fixedly connected to the end of the rotating shaft 16, the first engaging wheel 15 and the second engaging wheel 17 can be engaged or disengaged, the second spring 18 is sleeved on the spline shaft 14, and the second spring 18 pushes the first engaging wheel 15 and the second engaging wheel 17 to engage. The movement of the chuck 3 and the pressure plate 4 is driven by the rotating shaft 16.

[0025] It also includes a first gear 19, a first rack 20, a second gear 21, a second rack 22, and a bevel gear shaft assembly 23. The first gear 19 is fixedly connected to the end of the rotating shaft 16. The first rack 20 is meshed on both sides of the first gear 19. The two first racks 20 are respectively fixedly connected to the chuck 3 and the pressure plate 4. The second gear 21 is rotatably connected to the frame 1. The second rack 22 is meshed on both sides of the second gear 21. The two second racks 22 are respectively fixedly connected to the two connecting pieces 6. The bevel gear shaft assembly 23 links the output shaft of the motor 11 with the second gear 21.

[0026] In the above embodiments, driven by the same motor 11, the system first completes the rigid clamping and centering of the long angle iron. Then, the transmission path automatically "slips" (idles). Through the same motor 11, the movement of the shoe 3, the pressure plate 4, and the two clamping plates 5 is driven. When performing the clamping, positioning, and centering operation, the motor 11 rotates, which drives the mounting part 12 to rotate. The mounting part 12 drives the spline sleeve 13 and the spline shaft 14 to rotate. Due to the action of the second spring 18, the first engagement wheel 15 and the second engagement wheel 17 are in a meshing state, which in turn drives the rotating shaft 16 and the first gear 19 to rotate, so that the two first racks 20 move synchronously. The shoe 3 and the pressure plate 4 move closer to each other, the long angle iron is inserted into the shoe 3, and the pressure plate 4 cooperates with the shoe 3 to clamp and center the long angle iron.

[0027] Meanwhile, the motor 11 drives the second gear 21 to rotate through the bevel gear shaft group 23 (composed of multiple bevel gears and transmission shafts, see attached figure, the specific number and position of which are not limited). The second gear 21 drives the second racks 22 on both sides to move, so that the two connecting pieces 6 move closer to each other, and then the two clamping plates 5 move closer to each other. During this process, after the long angle iron is clamped, the motor 11 continues to rotate, while the first engaging wheel 15 and the second engaging wheel 17 slip relative to each other until the pressure block 9 presses against the pressure sensor 10, at which point the first motor 11 stops. That is, the entire process first clamps the long angle iron, and then the transmission mechanism that clamps the long angle iron idles and slips until the short angle iron is clamped and stabilized, at which point the motor 11 stops running.

[0028] After welding is completed, motor 11 reverses. As mentioned above, the first engagement wheel 15 and the second engagement wheel 17 will spin and slip until the two clamping plates 5 are reset and motor 11 stops (this is achieved by using a limit switch or position sensor, which will not be described in detail for the sake of clarity of existing technology).

[0029] Specifically, it also includes a guide plate 24, which is connected to the side of the clamping plate 5. The guide plate 24 is used to guide the short angle iron. The clamping plate 5 is L-shaped, and the clamping entrance of the shoe 3 is opened as an inclined surface.

[0030] In the above embodiments, the guide plate 24 facilitates the rapid introduction of short angle iron and forms a stable structure with the clamping plate 5 to stably limit the short angle iron. The clamping plate 5 is set as "L" shape, which can clamp the side of the cross-section of the short angle iron and provide sufficient welding space for the welding torch 2 to prevent interference with the operation of the welding torch 2. The entrance of the shoe 3 is set as a slope to facilitate the insertion of the side plate of the long angle iron into the shoe 3.

[0031] Specifically, it also includes a first support 25, a second support 26, and a magnet 27. The first support 25 is fixed to the frame 1 and is used to support the short angle iron. The second support 26 is connected to the upper side of the frame 1, and the long angle iron abuts against the second support 26. The magnet 27 is embedded in the second support 26.

[0032] In the above embodiments, the first support 25 facilitates the placement of the short angle iron, the second support 26 facilitates the initial positioning of the long angle iron, and the magnet 27 attracts the long angle iron to make it vertical and stable, which facilitates subsequent positioning and clamping operations.

[0033] The working principle of this utility model is as follows: When performing the welding operation of the "T" type bracket, firstly, the short angle iron is placed horizontally on the first support 25, and then the long angle iron is placed vertically against the second support 26. The magnet 27 attracts the long angle iron to keep it vertical.

[0034] Then, the motor 11 is run. The power of the motor 11 is transmitted through two paths. The first path is that the motor 11 drives the mounting part 12 to rotate. The mounting part 12 drives the spline sleeve 13, spline shaft 14, and first engagement wheel 15 to rotate. Due to the elastic force of the second spring 18, the first engagement wheel 15 and the second engagement wheel 17 mesh at this time. The rotation of the second engagement wheel 17 drives the rotating shaft 16. The rotating shaft 16 drives the first gear 19, causing the first racks 20 on both sides to come closer together. This causes the shoe 3 and the pressure plate 4 to come closer together. Due to the inclined surface on the shoe 3, the long angle iron side plate is quickly inserted into the shoe 3. The pressure plate 4 and the shoe 3 cooperate to stably clamp the long angle iron and center it. After the shoe 3 and the pressure plate 4 stably clamp the long angle iron, the movement of the shoe 3 and the pressure plate 4 is restricted and they no longer move. At this time, the first engagement wheel 15 and the second engagement wheel 17 slip.

[0035] The second path involves the motor 11 simultaneously driving the bevel gear shaft assembly 23 to rotate, causing the second gear 21 to rotate simultaneously. The two second racks 22 move closer together, and the connecting parts 6, guide rods 7, and clamping plates 5 on both sides move. The two clamping plates 5 move closer together to clamp the short angle iron. Due to the action of the guide plate 24, the short angle iron is guided and limited. The short angle iron is restricted and clamped within the structure formed by the clamping plate 5 and the guide plate 24. The short angle iron is also centered until the first spring 8 is compressed. The pressure block 9 on the clamping plate 5 abuts against the pressure sensor 10. The control system of the equipment receives the signal and controls the motor 11 to stop running. Then, the welding torches 2 on both sides are operated to perform welding operations.

[0036] After welding is completed, motor 11 reverses, clamp shoe 3 and pressure plate 4 reset, clamp shoe 3 and pressure plate 4 are restricted from moving, first engagement wheel 15 and second engagement wheel 17 slip relative to each other again, while the two clamping plates 5 continue to move until clamping plates 5 reset, motor 11 stops, the welded "T" frame can be removed, and the next work cycle can be started.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
