Description

Technical Field

[0001] This utility model relates to the field of support column welding technology, specifically a support column welding device. Background Technology

[0002] In building structures, mechanical equipment installation, and various engineering fields, the connection between the supporting columns and the base plate is a key link to ensure structural stability and load-bearing capacity.

[0003] However, traditional welding between support columns and base plates relies on the operator's visual judgment and experience, which is cumbersome, reduces welding efficiency, and causes centering errors, resulting in uneven weld joints that affect the mechanical properties of the weld joints and the overall stability of the structure. To address these issues, the inventors have proposed a support column welding device. Utility Model Content

[0004] In order to solve the problem of automatic alignment during welding between the support column and the base plate, the purpose of this utility model is to provide a support column welding device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a support column welding device, including a base, a rotating platform rotatably connected to the top of the base, a placement seat fixedly connected to the top of the rotating platform, a base plate placed on the top of the placement seat, a positioning component one provided on the placement seat, the positioning component one being used to position the base plate, an mounting plate fixedly connected to the top of the base near the rotating platform, a movable seat slidably connected to the mounting plate near the rotating platform, a positioning component two provided on the movable seat, a support column body placed on the top of the base plate, and the positioning component two being used to position the support column body.

[0006] Preferably, the turntable is rotatably connected inside the placement base. The turntable has centrally symmetrically distributed arc-shaped grooves. The top of the placement base has centrally symmetrically distributed transverse grooves. A slider is slidably engaged inside the transverse grooves. A guide post is fixedly connected to the bottom of the slider. The guide post is movably engaged in the arc-shaped groove. A positioning block is fixedly connected to the top of each slider. The opposite side of the positioning block contacts the base plate. A sliding groove is provided on one side of the placement base. An unlocking block is fixedly connected to one side of the turntable. The unlocking block is slidably engaged in the sliding groove. An electric cylinder is rotatably mounted on the side of the placement base near the unlocking block. The piston rod of the electric cylinder is rotatably connected to the unlocking block.

[0007] Preferably, the second positioning component includes a fixed plate, which is fixedly connected to one side of the movable seat. A bidirectional lead screw is rotatably connected between the two fixed plates. Two symmetrically distributed clamping plates are threaded to the outer side of the bidirectional lead screw. The clamping plates are slidably connected to the movable seat. V-grooves are formed on opposite sides of the clamping plates. A servo motor is fixedly installed on one side of one of the fixed plates. The drive end of the servo motor is fixedly connected to the bidirectional lead screw. A mounting seat is fixedly connected to the inner wall of the V-groove. Ball bearings are rolled inside the mounting seat. The center positions of the two clamping plates are on the same straight line as the center position of the placement seat.

[0008] Preferably, a threaded rod is rotatably connected to one side of the support column body, the movable seat is threaded to the outside of the threaded rod, and a stepper motor is fixedly installed at the top of the mounting plate, with the drive end of the stepper motor fixedly connected to the threaded rod.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. By extending the piston rod of the electric cylinder and utilizing the cooperation between the guide column and the arc groove, the three sliders and the interior of the transverse flue groove are simultaneously driven to move linearly towards or away from the center of the placement seat, positioning the base plate so that the base plate is placed at the top center of the placement seat. The servo motor drives the bidirectional lead screw to rotate, and at the same time drives the two clamping plates to move along the outside of the bidirectional lead screw towards one side of the support column body, aligning the position of the support column body. Since the center position is on the same straight line as the center position of the placement seat, the center line position of the support column body always corresponds to the center line position of the base plate, thereby achieving precise docking between the support column body and the base plate, further improving the welding efficiency between the support column and the base plate.

[0011] 2. The rotating platform drives the placement seat to rotate, which facilitates the welding of the mating surfaces of the base plate and the support column body. The stepper motor drives the threaded rod to rotate, which in turn drives the moving seat to move vertically along one side of the mounting plate. This allows the height of the positioning component two to be adjusted according to the height of the support column, further improving the equipment's usability. Attached Figure Description

[0019] 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.

[0020] Example: Figure 1-5 As shown, this utility model provides a support column welding device, including a base 1, a rotating platform 2 rotatably connected to the top of the base 1, a placement seat 3 fixedly connected to the top of the rotating platform 2, a base plate 5 placed on the top of the placement seat 3, a positioning component 4 provided on the placement seat 3 for positioning the base plate 5, an mounting plate 6 fixedly connected to the top of the base 1 near the rotating platform 2, a movable seat 7 slidably connected to the mounting plate 6 near the rotating platform 2, a positioning component 8 provided on the movable seat 7, and a support column body 9 placed on the top of the base plate 5, the positioning component 8 for positioning the support column body 9.

[0021] Positioning component 4 includes a turntable 41, which is rotatably connected inside the placement base 3. The turntable 41 has arc-shaped grooves 42 that are centrally symmetrically distributed. The top of the placement base 3 has transverse grooves 43 that are centrally symmetrically distributed. A slider 44 is slidably engaged inside the transverse groove 43. A guide post 45 is fixedly connected to the bottom of the slider 44. The guide post 45 is movably engaged in the arc-shaped groove 42. A positioning block 46 is fixedly connected to the top of each slider 44. The opposite side of the positioning block 46 is in contact with the base plate 5.

[0022] By adopting the above technical solution, by rotating the turntable 41, the cooperation between the guide column 45 and the arc groove 42 is used to drive the three sliders 44 to move linearly towards or away from the center of the placement seat 3. The cooperation between the positioning blocks 46 is used to position the base plate 5 so that the base plate 5 is placed at the top center of the placement seat 3.

[0023] A groove 47 is provided on one side of the placement seat 3, and an unlocking block 48 is fixedly connected to one side of the turntable 41. The unlocking block 48 is slidably engaged in the groove 47. An electric cylinder 49 is rotatably installed on the side of the placement seat 3 near the unlocking block 48. The piston rod of the electric cylinder 49 is rotatably connected to the unlocking block 48.

[0024] By adopting the above technical solution, the extension and retraction of the piston rod of the electric cylinder 49 pushes the unlocking block 48 to slide along the inside of the slide groove 47, while simultaneously rotating the turntable 41, thereby achieving the centering operation of the positioning component 4.

[0025] Positioning component 2 8 includes a fixing plate 81, which is fixedly connected to one side of the movable seat 7. A bidirectional lead screw 82 is rotatably connected between the two fixing plates 81. Two symmetrically distributed clamping plates 83 are threaded to the outer side of the bidirectional lead screw 82. The clamping plates 83 are slidably connected to the movable seat 7. V-grooves 84 are provided on the opposite side of each clamping plate 83. A servo motor 87 is fixedly installed on one side of one of the fixing plates 81. The drive end of the servo motor 87 is fixedly connected to the bidirectional lead screw 82.

[0026] By adopting the above technical solution, the servo motor 87 drives the bidirectional lead screw 82 to rotate, and at the same time drives the two clamping plates 83 to move symmetrically along the outside of the bidirectional lead screw 82, so that the center position between the two clamping plates 83 remains unchanged, thereby realizing the centering operation of the support column body 9.

[0027] The inner wall of the V-groove 84 is fixedly connected to the mounting base 85, and the inside of the mounting base 85 is connected to the ball bearing 86.

[0028] By adopting the above technical solution, by setting the ball bearing 86, the sliding friction between the contact surface of the clamping plate 83 and the support column body 9 is converted into rolling friction, thereby reducing the friction between the contact surface of the ball bearing 86 and the V-groove 84, so that the support column body 9 can still rotate while being clamped and positioned.

[0029] The center positions of the two clamps 83 and the center position of the placement seat 3 are on the same straight line.

[0030] By adopting the above technical solution, since the center position of the clamping plate 83 and the center position of the placement seat 3 are on the same straight line, the center line position of the support column body 9 always corresponds to the center line position of the base plate 5, thereby achieving precise docking between the support column body 9 and the base plate 5.

[0031] A threaded rod 10 is rotatably connected to one side of the support column body 9, and the movable seat 7 is threadedly connected to the outside of the threaded rod 10. A stepper motor 11 is fixedly installed on the top of the mounting plate 6, and the drive end of the stepper motor 11 is fixedly connected to the threaded rod 10.

[0032] By adopting the above technical solution, the stepper motor 11 drives the threaded rod 10 to rotate, and at the same time drives the moving seat 7 to move vertically along one side of the mounting plate 6, thereby adjusting the height of the positioning component 8 according to the height of the support column, further improving the application range of the equipment.

[0033] Working principle: When welding the support column body 9 and the base plate 5, the base plate 5 is placed on the top of the placement seat 3 and located between the three positioning blocks 46. The extension of the piston rod of the electric cylinder 49 pushes the unlocking block 48 to slide along the inside of the slide groove 47. At the same time, the turntable 41 is rotated. The cooperation between the guide column 45 and the arc groove 42 drives the three sliders 44 to move linearly towards or away from the center of the placement seat 3. The cooperation between the positioning blocks 46 positions the base plate 5 so that the base plate 5 is placed at the top center of the placement seat 3.

[0034] The support column body 9 is placed vertically at the top of the base plate 5 and between the two clamping plates 83. The servo motor 87 drives the bidirectional lead screw 82 to rotate, and at the same time drives the two clamping plates 83 to move along the outside of the bidirectional lead screw 82 to one side of the support column body 9, so as to center the position of the support column body 9. Since the center position is on the same straight line as the center position of the placement seat 3, the center line position of the support column body 9 always corresponds to the center line position of the base plate 5, thereby achieving precise docking between the support column body 9 and the base plate 5.

[0035] Then, the rotating platform 2 drives the placement seat 3 to rotate, which facilitates the welding of the mating surfaces of the base plate 5 and the support column body 9. The stepper motor 11 drives the threaded rod 10 to rotate, which in turn drives the moving seat 7 to move vertically along one side of the mounting plate 6. This adjusts the height of the positioning component 8 according to the height of the support column, further improving the equipment's usability.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
