Description

Technical Field

[0001] This utility model relates to the field of welding clamping fixture technology, specifically an automated rectangular tube column base plate welding clamping fixture. Background Technology

[0002] Rectangular column base plates are crucial connecting components in steel structure engineering. They are primarily used to connect rectangular columns to the foundation, serving to transfer loads and fix the column's position. Welding is required during the fabrication of rectangular column base plates, necessitating the use of welding clamping fixtures. These fixtures are specialized tools for welding rectangular column base plates, their core function being to ensure the positional accuracy and stability of the components during welding through precise positioning and reliable clamping, thereby improving welding quality and efficiency.

[0003] Existing welding clamping fixtures mostly clamp and fix column base plates from both sides, resulting in incomplete constraint and weak resistance to deformation. Simultaneous clamping from all four sides requires an additional power source, reducing the effectiveness of the device and making it inconvenient to use. Therefore, we propose an automated welding clamping fixture for rectangular tube column base plates. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automated rectangular tube column base plate welding clamping fixture. This fixture solves the problems that most welding clamping fixtures clamp and fix the column base plate from both sides, resulting in incomplete constraint and weak resistance to deformation. Furthermore, clamping from all four sides simultaneously requires an additional power source, which reduces the effectiveness of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automated rectangular column base plate welding clamping fixture includes a support base. The support base has equidistantly spaced sliding grooves inside, and connecting frames are slidably connected inside the grooves. Two of the connecting frames have first clamping plates fixedly connected to their tops, and these first clamping plates are slidably connected to the support base. The other two connecting frames have connecting plates fixedly connected to their tops. Limiting rods are symmetrically slidably connected inside the connecting plates. A second clamping plate is fixedly connected to one end of each limiting rod. Anti-slip pads are provided on one side of both the second and first clamping plates. A threaded rod is threadedly connected inside the connecting plates, and the threaded rod is rotatably connected to the second clamping plate. The support base has an adjustment mechanism that cooperates with the connecting frames.

[0007] The adjustment mechanism includes a rotating shaft, which is rotatably connected inside the support base. A turntable is fixedly connected to the outside of the rotating shaft. Connecting grooves are equidistantly opened inside the turntable. A connecting block that mates with the connecting grooves is fixedly connected to one side of the connecting frame.

[0008] In a preferred embodiment, a support frame is symmetrically fixedly connected to the bottom of the support base, and mounting holes are equidistantly provided inside the support frame.

[0009] The technical advantage of adopting the above-mentioned further solution is that the support frame and mounting holes facilitate the installation and fixing of the device with bolts. During installation, it is only necessary to align the mounting holes with the preset hole positions to quickly complete the positioning of the device, which facilitates subsequent installation.

[0010] In a preferred embodiment, a limiting slide rod is fixedly connected to the inner wall of the chute, and the connecting frame is slidably connected to the limiting slide rod.

[0011] The technical effect of adopting the above-mentioned further solution is that the movement of the connecting frame can be limited by setting the limiting slide bar, so that the connecting frame can only slide along the limiting slide bar, preventing it from deviating during movement.

[0012] In a preferred embodiment, a limiting block is fixedly connected to the end of the limiting rod away from the second clamping plate, and the outer side of the limiting rod is provided with a scale.

[0013] The technical effect of adopting the above-mentioned further solution is that the limiting block can be used in conjunction with the limiting rod to limit the movement of the second clamping plate and prevent deviation. The distance the limiting rod moves can be observed by setting the scale, and the position of the second clamping plate can be pre-adjusted according to the size of the plate.

[0014] In a preferred embodiment, an operating knob is fixedly connected to the end of the threaded rod away from the second clamping plate, and the outer side of the operating knob is provided with anti-slip texture.

[0015] The technical effect of adopting the above-mentioned further solution is that the anti-slip texture can increase the friction, increase the roughness of the contact surface, improve the grip friction and operation stability, facilitate the rotation of the operating knob, and drive the threaded rod to rotate through the operating knob.

[0016] In a preferred embodiment, a support block is fixedly connected to the inner wall of the support base, a fixed rod is fixedly connected between the support block and the support base, an adjusting block is slidably connected to the outer side of the fixed rod, a connecting rod is fixedly connected to one side of the adjusting block, a rack is fixedly connected to one end of the connecting rod, and a gear that cooperates with the rack is fixedly connected to the outer side of the rotating shaft.

[0017] The technical effect of adopting the above-mentioned further solution is that the movement of the adjusting block can be limited by the setting of the fixed rod, so that the adjusting block can only slide along the fixed rod, preventing it from deviating during movement. The adjusting block drives the rack to move through the connecting rod, thereby driving the gear to rotate. The gear drives the turntable to rotate through the rotating shaft.

[0018] In a preferred embodiment, a lead screw is rotatably connected between the support block and the support base, the adjusting block is threadedly connected to the lead screw, a servo motor is fixedly connected to the outside of the support base, and the output end of the servo motor is fixedly connected to the lead screw.

[0019] The technical effect of adopting the above-mentioned further solution is that the servo motor drives the lead screw to rotate, causing the adjusting block to slide along the fixed rod.

[0020] This utility model provides an automated rectangular tube column base plate welding clamping fixture. Compared with the prior art, it has the following advantages: This automated rectangular tube column base plate welding clamping fixture, through the setting of a servo motor, lead screw, adjusting block, connecting rod, rack, gear, adjusting mechanism, connecting frame, first clamping plate, connecting plate, threaded rod, and second clamping plate, realizes the function of centering and clamping during the welding of rectangular tube column base plates. It can keep the plate in a fixed position during welding, and ensure that the welding rod or welding wire evenly fills the weld during the welding process, avoiding defects such as uneven weld width and insufficient penetration depth caused by plate displacement, thus improving the welding quality and facilitating use; When welding the rectangular tube column base plate, the plate is placed on top of the support base, and the operating knob is turned. The operating knob drives the threaded rod to rotate, thereby moving the second clamping plate. The two sets of limit rods limit the movement of the second clamping plate to prevent deviation. The position of the limit rods can be observed through the scale, so the position of the second clamping plate can be pre-adjusted according to the size of the plate. After the adjustment is completed, the servo motor is started by the PLC controller on the outside of the support base. The servo motor drives the lead screw to rotate, so that the adjusting block slides along the fixed rod. The adjusting block drives the rack to move through the connecting rod, so that the gear rotates. The gear drives the turntable to rotate through the rotating shaft, so that the connecting groove and the connecting block cooperate. When the turntable rotates, it squeezes and drives the connecting block to move. The connecting block drives the connecting frame to slide along the limit slide rod, and then the plate is clamped and fixed on all four sides by the first clamping plate and the second clamping plate.

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Please see Figures 1 to 7 This utility model provides a technical solution:

[0038] An automated rectangular column base plate welding clamping fixture includes a support base 1. The support base 1 has equidistantly spaced sliding grooves 13 inside. Connecting frames 14 are slidably connected inside the sliding grooves 13. Two of the connecting frames 14 have first clamping plates 11 fixedly connected to their tops, and the first clamping plates 11 are slidably connected to the support base 1. The other two connecting frames 14 have connecting plates 2 fixedly connected to their tops. Limiting rods 25 are symmetrically slidably connected inside the connecting plates 2. One end of each limiting rod 25 is fixedly connected to a second clamping plate 21. One side of the second clamping plate 21... Anti-slip pads are provided on one side of the first clamping plate 11. A threaded rod 26 is threadedly connected inside the connecting plate 2. The threaded rod 26 is rotatably connected to the second clamping plate 21. An adjustment mechanism 3 is provided inside the support base 1 to cooperate with the connecting frame 14. The adjustment mechanism 3 includes a rotating shaft 31. The rotating shaft 31 is rotatably connected inside the support base 1. A turntable 32 is fixedly connected to the outside of the rotating shaft 31. A connecting groove 34 is equidistantly opened inside the turntable 32. A connecting block 33 that cooperates with the connecting groove 34 is fixedly connected to one side of the connecting frame 14.

[0039] In this scheme, an external power supply can provide power support for the device. When welding the column base plate of the rectangular tube column, the plate is placed on top of the support base 1. The rotation of the threaded rod 26 drives the second clamping plate 21 to move. The movement of the second clamping plate 21 can be limited by the setting of two sets of limiting rods 25 to prevent displacement. Thus, the position of the second clamping plate 21 can be pre-adjusted according to the size of the plate. The rotating shaft 31 drives the turntable 32 to rotate, so that the connecting groove 34 and the connecting block 33 cooperate. When the turntable 32 rotates, it squeezes and drives the connecting block 33 to move. The connecting block 33 drives the connecting frame 14 to slide. Then, the first clamping plate 11 and the second clamping plate 21 clamp and fix the plate on all four sides. Thus, the plate is centered and clamped when welding the column base plate of the rectangular tube column. This keeps the plate in a fixed position during welding, and the welding rod or welding wire fills the weld evenly during the welding process. This avoids defects such as uneven weld width and insufficient penetration depth caused by plate displacement, thus improving the welding quality.

[0040] like Figure 1 and Figure 2 As shown: In this scheme, the bottom of the support base 1 is symmetrically and fixedly connected to the support frame 12, and the support frame 12 has mounting holes equidistantly opened inside; the inner wall of the slide groove 13 is fixedly connected to the limiting slide rod 15, and the connecting frame 14 is slidably connected to the limiting slide rod 15.

[0041] In this design, the support frame 12 and the mounting holes facilitate the installation and fixing of the device with bolts. During installation, simply aligning the mounting holes with the preset hole positions allows for quick positioning of the device, facilitating subsequent installation. The limiting slide bar 15 limits the movement of the connecting frame 14, ensuring that the connecting frame 14 can only slide along the limiting slide bar 15, preventing it from shifting during movement.

[0042] like Figure 7 As shown: In this scheme, the end of the limiting rod 25 away from the second clamping plate 21 is fixedly connected to the limiting block 24, and the outer side of the limiting rod 25 is provided with a scale 22; the end of the threaded rod 26 away from the second clamping plate 21 is fixedly connected to the operating knob 23, and the outer side of the operating knob 23 is provided with anti-slip texture.

[0043] In this design, the anti-slip texture increases friction, improves the roughness of the contact surface, enhances grip and operational stability, and facilitates the rotation of the operating knob 23. The operating knob 23 drives the threaded rod 26 to rotate, thereby moving the second clamping plate 21. The movement of the second clamping plate 21 is limited by two sets of limiting rods 25 to prevent deviation. The position of the limiting rods 25 can be observed through the scale 22, allowing for pre-adjustment of the position of the second clamping plate 21 according to the size of the plate.

[0044] like Figure 3 , Figure 4 and Figure 5 As shown: In this scheme, a support block 4 is fixedly connected to the inner wall of the support base 1, a fixed rod 41 is fixedly connected between the support block 4 and the support base 1, an adjusting block 44 is slidably connected to the outer side of the fixed rod 41, a connecting rod 46 is fixedly connected to one side of the adjusting block 44, a rack 47 is fixedly connected to one end of the connecting rod 46, and a gear 43 that works with the rack 47 is fixedly connected to the outer side of the rotating shaft 31; a lead screw 42 is rotatably connected between the support block 4 and the support base 1, the adjusting block 44 is threadedly connected to the lead screw 42, a servo motor 45 is fixedly connected to the outer side of the support base 1, and the output end of the servo motor 45 is fixedly connected to the lead screw 42.

[0045] In this scheme, an external power supply can provide power support for the device. The servo motor 45 is started by the PLC controller on the outside of the support base 1. The servo motor 45 drives the lead screw 42 to rotate, causing the adjusting block 44 to slide along the fixed rod 41. The adjusting block 44 drives the rack 47 to move through the connecting rod 46, thereby driving the gear 43 to rotate. The gear 43 drives the turntable 32 to rotate through the rotating shaft 31, so that the connecting groove 34 and the connecting block 33 cooperate. When the turntable 32 rotates, it squeezes and drives the connecting block 33 to move. The connecting block 33 drives the connecting frame 14 to slide along the limiting slide rod 15. Then, the plate is clamped and fixed on all four sides by the first clamping plate 11 and the second clamping plate 21. This centering and clamping is performed when welding the column base plate of the rectangular tube column, which can keep the plate in a fixed position during welding. This allows the welding rod or welding wire to fill the weld evenly during the welding process, avoiding defects such as uneven weld width and insufficient penetration depth caused by plate displacement, thus improving the welding quality.

[0046] Working principle:

[0047] In use, an external power supply can provide power support for the device. When welding the column base plate of the rectangular tube column, the plate is placed on the top of the support base 1. The operating knob 23 is turned, which drives the threaded rod 26 to rotate, thereby driving the second clamping plate 21 to move. The movement of the second clamping plate 21 can be limited by the setting of two sets of limit rods 25 to prevent deviation.

[0048] The position of the limiting rod 25 can be observed through the scale 22, so that the position of the second clamping plate 21 can be pre-adjusted according to the size of the plate.

[0049] After adjustment, the servo motor 45 is started by the PLC controller on the outside of the support base 1. The servo motor 45 drives the lead screw 42 to rotate, causing the adjusting block 44 to slide along the fixed rod 41. The adjusting block 44 drives the rack 47 to move through the connecting rod 46, thereby driving the gear 43 to rotate. The gear 43 drives the turntable 32 to rotate through the rotating shaft 31, so that the connecting groove 34 and the connecting block 33 cooperate. When the turntable 32 rotates, it squeezes and drives the connecting block 33 to move. The connecting block 33 drives the connecting frame 14 to slide along the limiting slide rod 15. Then, the plate is clamped and fixed on all four sides by the first clamping plate 11 and the second clamping plate 21. This allows for centering and clamping when welding the column base plate of the rectangular tube column, keeping the plate in a fixed position during welding. This ensures that the welding rod or welding wire fills the weld evenly during the welding process, avoiding defects such as uneven weld width and insufficient penetration depth caused by plate displacement, thus improving the welding quality.
