Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a welding clamping fixture for anti-shaking irregular steel pipes. Background Technology

[0002] Special-shaped steel pipes refer to seamless steel pipes with cross-sectional shapes other than round pipes. They are widely used in structural components, mechanical parts and other fields. Special-shaped steel pipes can be divided into square, rectangular, equilateral triangle and other shapes according to their cross-sectional shape.

[0003] When grinding and processing equilateral triangular steel pipes, the steel pipes may shake due to the action of external forces. This not only affects the processing accuracy, but may also cause safety hazards to equipment and operators. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a non-swaying welding clamping fixture for irregularly shaped steel pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sway-resistant welding clamping fixture for irregularly shaped steel pipes includes a base plate. A fixing plate is mounted on the upper surface of the base plate via a guide assembly. The upper surface of the base plate is provided with a power assembly that moves the fixing plate up and down. Two support frames are fixedly connected to the upper surface of the fixing plate. Two dovetail grooves are formed at the top of the fixing plate, and sliders are movably connected in each of the two dovetail grooves. A pushing assembly that drives the two sliders to move is provided on the upper surface of the fixing plate. A clamping plate is detachably connected to the top of the sliders via bolts. A U-shaped frame is fixedly connected to the upper surface of the fixing plate. A second electric push rod is fixedly connected to the top of the U-shaped frame. A connecting plate is fixedly connected to the extended end of the second electric push rod. Pressure blocks are fixedly connected to both ends of the connecting plate.

[0006] As a further embodiment of this utility model, the guide assembly includes two guide rods, which are fixed to the upper surface of the base plate by bolts. Both ends of the fixing plate are fixedly connected to a fixing frame, and the fixing frame is slidably connected to the guide rod.

[0007] As a further embodiment of this utility model, the power assembly includes a first electric push rod, which is fixed to the upper surface of the base plate by bolts, and the extended end of the first electric push rod is fixed to the fixing plate.

[0008] As a further embodiment of this utility model, the pushing component includes a fixing block, which is fixed to the upper surface of the fixing plate by bolts. Two electric telescopic rods facing opposite directions are fixedly connected to the fixing block, and the two piston rods of the electric telescopic rods are respectively fixed to two sliders.

[0009] As a further improvement of this utility model, anti-slip pads are fixedly connected to the clamping surfaces of the clamping plate and the pressure block.

[0010] As a further embodiment of this invention, the connecting plate is located above the clamping plate.

[0011] As a further improvement of this utility model, the clamping plate is inclined and the pressure block has a V-shaped groove.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model uses clamping plates that move towards each other to clamp the side of the steel pipe. In conjunction with the connecting plate, the pressure block moves downward until it presses the top of the protruding triangular steel pipe. This, combined with the lateral clamping, achieves lateral and vertical restriction and fixation, preventing the triangular steel pipe from shaking or falling during welding and ensuring the subsequent welding quality.

[0013] 2. In this utility model, the friction between the clamping plate and the pressure block and the triangular steel pipe is enhanced by the anti-slip pad, which further prevents the steel pipe from sliding easily.

[0014] 3. This utility model guides the fixing plate through the guide component, preventing the fixing plate from tilting during the up and down movement. It can also adjust the height of the clamped triangular steel tube, thus improving the effectiveness of the device. Attached Figure Description

[0017] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0018] Reference Figures 1-4 A non-swaying welding clamping fixture for irregularly shaped steel pipes includes a base plate 5. A fixing plate 7 is installed on the upper surface of the base plate 5 through a guide assembly. Fixing brackets 2 are fixed to both ends of the fixing plate 7 by bolts. The guide assembly includes two guide rods 6, which are fixed to the upper surface of the base plate 5 by bolts. The fixing brackets 2 are slidably connected to the guide rods 6. The top ends of the two guide rods 6 can contact the lower surface of the fixing plate 7. By setting the guide assembly, the fixing plate 7 is guided, preventing the fixing plate 7 from tilting during the up and down movement. The upper surface of the base plate 5 is provided with a power assembly that moves the fixed plate 7 up and down. The power assembly includes a first electric push rod 4, which is fixed to the upper surface of the base plate 5 by bolts. The extended end of the first electric push rod 4 is fixed to the fixed plate 7 by bolts. The extension and retraction of the first electric push rod 4 causes the fixed plate 7 to move up and down along the guide rod 6 through the fixing frame 2 until it is adjusted to the required height.

[0019] It should be noted that the upper surface of the fixing plate 7 is fixed with two support frames 11 by bolts. The top of the support frame 11 is a platform structure for placing the equilateral triangular steel pipe. The top of the fixing plate 7 has two dovetail grooves 15, and each dovetail groove 15 is slidably connected to a slider 16. The dovetail grooves 15 can guide the slider 16. The upper surface of the fixed plate 7 is provided with a pushing assembly that drives the two sliders 16 to move. The pushing assembly includes a fixed block 13, which is fixed to the upper surface of the fixed plate 7 by bolts. Two electric telescopic rods 14 facing opposite directions are fixed to the fixed block 13 by bolts. The two electric telescopic rods 14 are independently controlled. The piston rods of the two electric telescopic rods 14 are fixed to the two sliders 16 by bolts respectively. The top of the slider 16 is detachably connected to a clamping plate 17 by bolts. The clamping plate 17 is set at an inclination of 60 degrees. Place the triangular steel pipe on top of the two support frames 11. At this time, the triangular steel pipe is located between the two clamping plates 17. Activate the switches of the two electric telescopic rods 14 respectively. The piston rod pushes the slider 16 to move towards each other along the dovetail groove 15, so that the clamping plates 17 on both sides clamp the side of the steel pipe. The anti-slip pad 3 enhances the friction and prevents lateral sliding.

[0020] In particular, a U-shaped frame 1 is fixed to the upper surface of the fixing plate 7 by bolts, a second electric push rod 8 is fixed to the top of the U-shaped frame 1 by bolts, a connecting plate 9 is fixed to the extended end of the second electric push rod 8 by bolts, and pressure blocks 10 are fixed to both ends of the connecting plate 9 by bolts. A V-shaped groove is provided on the pressure block 10; the V-shaped groove is set at 60 degrees, and the connecting plate 9 is located above the clamping plate 17. Anti-slip pads 3 are adhered to the clamping surfaces of the clamping plate 17 and the pressure block 10. The extension of the second electric push rod 8 causes the connecting plate 9 to move the pressure block 10 downward until the pressure block 10 presses the top of the triangular steel tube protrusion, thereby achieving lateral and vertical restriction and fixation to prevent the triangular steel tube from shaking during subsequent welding.

[0021] Working principle: When it is necessary to clamp the triangular steel pipe, Lateral positioning: Place the triangular steel tube on top of the two support frames 11, at which point the triangular steel tube is located between the two clamping plates 17; Vertical clamping: Activate the second electric push rod 8, drive the connecting plate 9 to move the pressure block 10 downward until the pressure block 10 clamps the top of the triangular steel tube protrusion, thus achieving vertical restriction and fixation; Lateral clamping: Start the electric telescopic rod 14 respectively, the piston rod pushes the slider 16 to move towards each other along the dovetail groove 15, so that the two side clamps 17 clamp the side of the steel pipe. The anti-slip pad 3 enhances the friction and prevents lateral sliding, avoiding the triangular steel pipe from shaking during subsequent welding.

[0022] Height adjustment: Activate the first electric push rod 4 to drive the fixed plate 7 to move up and down along the guide rod 6 via the fixed frame 2 to adjust to the required height.

[0023] The fixed triangular steel pipe is welded using external welding equipment.
