Description

Technical Field

[0001] This utility model belongs to the field of steel pipe processing technology, and in particular relates to a clamping device for welding steel pipe rods. Background Technology

[0002] Steel pipes are steel materials with hollow cross sections, whose length is much greater than their diameter or circumference. Steel pipe welding clamping devices are clamping devices used to secure the steel pipes to be welded, so as to facilitate welding at the joints of the steel pipes.

[0003] Chinese utility model patent CN220312350U discloses a clamping device for steel pipe welding, comprising a clamping frame, a horizontal component, and an alignment component. The horizontal component includes support platforms fixedly installed on both sides of the clamping frame, and a support frame fixedly installed at the center of the upper part of the support platforms. The clamping device for steel pipe welding described in this utility model uses a clamping table installed within the support frame at the upper part of the support platform to horizontally clamp the steel pipes placed on the upper parts of the support platforms on both sides, maintaining their horizontal alignment. This, combined with the opening and closing of the clamping plates on both sides between the support platforms and the clamping table, achieves horizontal and vertical alignment of the ends of the steel pipes after clamping and fixing them with the clamping frame. This ensures the accuracy of the connection between the ends of the steel pipes on both sides, improves the welding accuracy, and this clamping frame can ensure the horizontal and vertical alignment of the connection ends when welding steel pipes of various sizes.

[0004] However, the above-mentioned device has the following technical problems in actual use:

[0005] 1. The above-mentioned device places the bidirectional threaded rod on the top of the clamping frame and below the adjacent ends (the welding positions) of the two steel pipes. When welding the ends of the two adjacent steel pipes, the high-temperature welding slag produced may fall onto the clamping frame and the bidirectional threaded rod. After the high-temperature welding slag cools, the resulting residue will adhere to the bidirectional threaded rod and the clamping frame, forming protruding obstacles, which will hinder or affect the movement of the subsequent two slides.

[0006] Second, the steel pipes need to be rotated during the welding process to weld the ends of two adjacent steel pipes from all angles. The above-mentioned device lacks a rotation drive structure for the steel pipes, requiring manual intervention to rotate them during welding. This method consumes a lot of manpower and reduces production efficiency. Utility Model Content

[0007] This utility model provides a clamping device for welding steel pipe rods, aiming to solve the problems mentioned in the background art. In the above-mentioned device, because the bidirectional screw is set above the clamping frame, the high-temperature welding slag generated during steel pipe welding may fall onto the bidirectional screw. After the welding cools down, it will form an adhering substance on the bidirectional screw, thereby affecting the relative movement of the two slides. At the same time, the above-mentioned device lacks a rotation drive structure for the steel pipe, and manual rotation is still required, which greatly increases the labor cost.

[0008] This utility model is implemented as follows: a clamping device for welding steel pipe rods includes: a fixed platform with symmetrically fixed feet on its bottom wall; two placement platforms symmetrically fixed on the top of the fixed platform, each placement platform supporting a steel pipe body, with adjacent ends of the two steel pipe bodies abutting against each other; and a clamping mechanism having: a first sliding groove formed on each placement platform; two sliding frames symmetrically slidably connected in each first sliding groove; the two sliding frames being arranged opposite each other on both sides of the steel pipe body; and a driving assembly provided at the bottom of the fixed platform. The two sliding frames on the placement platform are movably connected, and each placement platform is provided with a pipe rotating mechanism. The pipe rotating mechanism is located above the steel pipe body and abuts against the outer wall of the steel pipe body. The pipe rotating mechanism is used to drive the two steel pipe bodies on both sides to rotate synchronously and in the same direction. In this scheme, the bidirectional screw is set at the bottom of the fixed platform. When welding the adjacent ends of the two steel pipe bodies, the high-temperature welding slag produced will fall onto the fixed platform, avoiding the problem of high-temperature welding slag falling onto the bidirectional screw, thereby avoiding the problem of the two moving frames being obstructed due to the high-temperature welding slag cooling on the bidirectional screw.

[0009] Furthermore, in this device, when the steel pipe body is supported on the placement platform for welding, the electric push rod pushes the lifting block down, causing the drive roller to abut against the outer wall of the top of the steel pipe body. Subsequently, the clamping plates on both sides clamp the steel pipe body from both sides, while the rollers abut against the outer wall of the sensor body from both sides. When the drive roller rotates, it will transfer the rotational kinetic energy to the steel pipe body through friction. With the support and cooperation of the rollers on both sides, the steel pipe body rotates, and the two steel pipe bodies rotate synchronously, thus avoiding the amount of work required for manual rotation.

[0010] Preferably, the driving assembly includes: two first mounting seats symmetrically disposed on the bottom wall of the fixed platform; a bidirectional screw is rotatably connected between the two first mounting seats; a first motor is fixedly connected to the side wall of one of the first mounting seats, with its output end fixedly connected to the end of the bidirectional screw; a second mounting seat is also fixedly connected to the bottom wall of the fixed platform on both sides of each first mounting seat; a guide rod is fixedly installed between the two second mounting seats on the same side; a movable frame is screwed onto each of the two opposite threaded sections of the bidirectional screw, and the two ends of the movable frame are slidably connected to the guide rods on both sides; a second sliding groove is also provided on the fixed platform corresponding to the two first sliding grooves; the bottom end of the sliding frame passes through the... The second slide groove is fixed to the corresponding side of the movable frame. In this scheme, when the output end of the first motor rotates, it drives the bidirectional screw to rotate. The bidirectional screw then controls the movable frame threaded to its two opposite threaded sections to move towards or away from each other under the guidance and limitation of the guide rods on both sides. Since each movable frame has a sliding frame fixedly installed at both ends, when the two movable frames approach each other, they will drive the two sliding frames on the same side end to approach each other in the first slide groove (second slide groove). Conversely, when the two movable frames move away from each other, they will drive the two sliding frames on the same side to move away from each other. When the two sliding frames approach each other, they will clamp and fix the steel pipe body between them.

[0011] Preferably, a retaining plate is fixedly installed on the side wall of each of the two sliding frames that are close to each other, and the two retaining plates are respectively arranged opposite to each other on both sides of the steel pipe body. In this scheme, when the two sliding frames on the placement platform approach each other, they will drive the two retaining plates to move closer to the outer wall of the side of the steel pipe body, so that the retaining plates progressively fit against the outer wall of the steel pipe body, thereby achieving stable clamping and fixing of the steel pipe body.

[0012] Preferably, the pipe rotating mechanism includes: two symmetrically upright plates fixed to the placement platform, a horizontal plate fixed between the top ends of the two upright plates, a lifting block provided on the bottom wall of the horizontal plate, a rotating groove provided on the bottom wall of the lifting block, a rotating shaft rotatably connected in the rotating groove, a drive roller fixedly installed on the outer wall of the rotating shaft, and a second motor fixedly connected to one side of the outer wall of the lifting block, with its output end fixedly connected to one end of the rotating shaft. In this scheme, after the two clamping plates limit and fix the steel pipe body, the drive roller is now in contact with the top outer wall of the steel pipe body. The output end of the second motor drives the rotating shaft to rotate, the rotating shaft drives the drive roller to rotate, and the drive roller drives the steel pipe body to rotate using friction, thereby achieving the purpose of rotating and controlling the steel pipe body.

[0013] Preferably, an electric push rod is also fixedly installed on the top wall of the horizontal plate, with its output end passing through the horizontal plate and fixedly installed on the top wall of the lifting block; in this scheme, the electric push rod can control the lifting block to move up and down, thereby facilitating manual loading and unloading of the steel pipe body on the placement platform, while making the drive roller stably attached to the top outer wall of the steel pipe body.

[0014] Preferably, the abutment plate is C-shaped, with accommodating cavities at both ends, and mating rollers are rotatably connected within the accommodating cavities. The mating rollers are attached to the outer wall of the steel pipe body. In this design, the mating rollers at both ends of the abutment plate can reduce the friction between the steel pipe body and the abutment plate, while guiding the rotation of the steel pipe body to ensure the stability of the steel pipe body during rotation.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a clamping device for welding steel pipe poles.

[0016] 1. In this device, the bidirectional screw is set at the bottom of the fixed platform. When welding the adjacent ends of the two steel pipe bodies, the high-temperature welding slag produced will fall onto the fixed platform, avoiding the problem of high-temperature welding slag falling onto the bidirectional screw. This avoids the problem of the two moving frames being obstructed due to the high-temperature welding slag cooling on the bidirectional screw.

[0017] 2. When the steel pipe body is supported on the placement platform for welding, the electric push rod pushes the lifting block to move down, so that the drive roller abuts against the outer wall of the top of the steel pipe body. Then, the two side clamping plates clamp the steel pipe body from both sides, and at the same time, the rollers abut against the outer wall of the sensor body from both sides. When the drive roller rotates, it will transfer the rotational kinetic energy to the steel pipe body through friction. With the support and cooperation of the rollers on both sides, the steel pipe body rotates. The two sides of the steel pipe body rotate synchronously, thus avoiding the amount of work required for manual rotation. Attached Figure Description

[0030] See also Figure 1-3This utility model provides a technical solution: a clamping device for welding steel pipe rods, comprising: a fixed platform 1, on which symmetrical feet 11 are fixedly installed; two placement platforms 12 are also fixedly installed symmetrically on the top of the fixed platform 1, each placement platform 12 bearing a steel pipe body, with adjacent ends of the two steel pipe bodies abutting each other; a clamping mechanism 2, which has: a first sliding groove 21 opened on each placement platform 12; two sliding frames 22 symmetrically slidably connected in each first sliding groove 21; the two sliding frames 22 are arranged opposite to each other on both sides of the steel pipe body; a driving assembly 23 is also provided at the bottom of the fixed platform 1, the driving assembly 23 being movably connected to the two sliding frames 22 on each placement platform 12; and a pipe rotating mechanism 3 is provided on each placement platform 12, the pipe rotating mechanism 3 being located above the steel pipe body and abutting against the outer wall of the steel pipe body, the pipe rotating mechanism 3 being used to drive the two steel pipe bodies on both sides to rotate synchronously and in the same direction.

[0031] Specifically, the device can also have a collection box placed on the fixed platform 1. The top wall of the collection box has a collection cavity. The collection box is located between the two placement platforms 12 and below the adjacent ends of the two steel pipe bodies. When welding is performed, the welding slag will fall into the collection cavity. After the device is completed, the staff can directly remove the collection box from the fixed platform 1 to deal with the welding slag in the collection cavity and prevent the welding slag from falling onto the fixed platform 1 and affecting the overall appearance of the device.

[0032] Furthermore, the drive assembly 23 includes: two first mounting seats 231 symmetrically disposed on the bottom wall of the fixed platform 1, a bidirectional screw 232 rotatably connected between the two first mounting seats 231, a first motor 233 fixedly connected to the side wall of one of the first mounting seats 231, the output end of which is fixedly connected to the end of the bidirectional screw 232, a second mounting seat 234 fixedly connected to the bottom wall of the fixed platform 1 on both sides of each first mounting seat 231, a guide rod 235 fixedly installed between the two second mounting seats 234 on the same side, a movable frame 236 screwed onto the two opposite threaded sections of the bidirectional screw 232, and the two ends of the movable frame 236 slidably connected to the guide rods 235 on both sides, a second slide groove 13 corresponding to the two first slide grooves 21 on the fixed platform 1, the bottom end of the sliding frame 22 passing through the second slide groove 13 and fixedly connected to the movable frame 236 on the corresponding side.

[0033] Furthermore, abutment plates 221 are fixedly installed on the side walls of the two sliding frames 22 that are close to each other, and the two abutment plates 221 are respectively arranged opposite to each other on both sides of the steel pipe body.

[0034] Furthermore, the rotating mechanism 3 includes: two vertical plates 31 that are symmetrically and fixedly fixed on the placement platform 12; a horizontal plate 32 is fixedly fixed between the top ends of the two vertical plates 31; a lifting block 33 is provided on the bottom wall of the horizontal plate 32; a rotating groove 331 is provided on the bottom wall of the lifting block 33; a rotating shaft 34 is rotatably connected in the rotating groove 331; a drive roller 35 is fixedly installed on the outer wall of the rotating shaft 34; and a second motor 36 is fixedly connected to one side of the outer wall of the lifting block 33, with its output end fixedly connected to one end of the rotating shaft 34.

[0035] Furthermore, an electric push rod 37 is fixedly installed on the top wall of the horizontal plate 32, with its output end passing through the horizontal plate 32 and fixedly installed on the top wall of the lifting block 33.

[0036] Furthermore, the clamping plate 221 is C-shaped, with accommodating cavities at both ends, and mating rollers 38 are rotatably connected inside the accommodating cavities, with the mating rollers 38 adhering to the outer wall of the steel pipe body.

[0037] Specifically, the first slide 21 in this device can be divided into two sections, and the two sections of the first slide 21 are spaced apart. A support platform can be fixedly installed between the two sections of the first slide 21. The support platforms are spaced apart, and each support platform is rotatably connected to a support roller on its top. When the steel pipe body is placed, the steel pipe body overlaps on the two support rollers. The support rollers can reduce the friction between the steel pipe body and the placement platform 12, thereby ensuring the stability of the steel pipe body when it rotates.

[0038] Working principle and usage process of this utility model:

[0039] Two steel pipe bodies to be welded are placed on the placement platform 12, so that the adjacent ends of the two steel pipe bodies are pressed against each other. Then, the output end of the first motor 233 controls the bidirectional screw 232 to rotate. The bidirectional screw 232 drives the movable frame 236 screwed on its two threaded sections to move towards each other. Thus, the movable frame 236 controls the two sliding frames 22 in each first slide groove 21 to move towards each other, so that the two sliding frames 22 move towards the steel pipe body and the abutment plate 221 abuts and clamps the steel pipe body. The mating rollers 38 on both ends of the abutment plate 221 are attached to the outer wall of the steel pipe body.

[0040] Subsequently, the output end of the electric push rod 37 extends to push the lifting block 33 downward, causing the drive roller 35 to move downward and press against the outer wall of the top of the steel pipe body. The output end of the second motor 36 controls the rotating shaft 34 to rotate, and the rotating shaft 34 controls the drive roller 35 to rotate. The drive roller 35 transmits the rotational kinetic energy to the steel pipe body, and then controls the rotation of the steel pipe body.

[0041] It should be explained that this device is located below the welding head of the welding device, and the welding head is located above the adjacent ends of the two steel pipe bodies. When the steel pipe bodies are rotated, the welding head moves down to contact the position where the ends of the two steel pipe bodies abut, thereby performing welding processing on the two adjacent steel pipe bodies.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
