Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metal pipe processing technology, and specifically relates to a welding and cutting tool for metal pipe processing. Background Technology
[0002] Metal pipe processing welding and cutting fixtures refer to auxiliary support and positioning devices in the processing of metal pipes for welding and cutting. They are used to fix, adjust and stabilize the workpiece during welding and cutting. The fixtures themselves do not include welding or cutting structures.
[0003] During the aforementioned processing steps, tooling is required. While existing welding and cutting tooling can meet the basic needs of auxiliary support and positioning of metal pipes, it typically only supports and fixes one side of the pipe at the cutting location, leaving the other side often suspended. This causes the pipe to vibrate or deform due to uneven stress during processing, especially when cutting or welding long or large-diameter pipes, where the cantilever effect is significant, severely affecting processing accuracy and operational safety. Furthermore, when the pipe undergoes localized thermal expansion under high temperatures, the side lacking effective support is prone to bending or shifting, leading to quality problems such as skewed cuts and misaligned welds; therefore, it cannot fully meet the needs of users. Utility Model Content
[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a welding and cutting fixture for metal pipe processing. It not only meets the basic requirements for auxiliary support and positioning of metal pipes, but also provides support and fixation on both sides of the metal pipe welding and cutting processing position, thereby better meeting people's usage needs.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a welding and cutting fixture for metal pipe processing, including a processing table. The top of the processing table has a support groove with an arc-shaped inner wall, provided along the left-right direction by a vertical rod. A processing through hole is also provided on the support groove. Support plates are also provided between the processing table and the support groove, located on both sides of the processing through hole. Sliding connecting frames are also provided on the processing table, located on the front and rear sides of the support groove. A first clamping module is slidably mounted on one side of the two sliding connecting frames, and a second clamping module is slidably mounted on the other side of the two sliding connecting frames. A discharge through hole is also provided at the bottom of the support groove. With a discharge through hole at the bottom of the support groove, metal chips or slag generated during welding and cutting can fall and be discharged in a timely manner, avoiding accumulation that affects processing quality or damages the equipment.
[0006] As a further improvement of this utility model, the first pressing module includes a first pressing frame that is slidably connected to the sliding connecting frame. A first telescopic push rod is vertically arranged on the first pressing frame. A first pressing plate with an arc-shaped bottom wall is arranged at the lower end of the first telescopic push rod. A first guide cylinder is arranged on the first pressing frame. A first guide rod that is inserted into the first guide cylinder is arranged on the first pressing plate.
[0007] As a further improvement of this utility model, the first clamping module includes a second clamping frame slidably connected to the sliding connecting frame. A second telescopic push rod is vertically arranged on the second clamping frame, and a second clamping plate with an arc-shaped bottom wall is provided at the lower end of the second telescopic push rod. A second guide cylinder is provided on the second clamping frame, and a second guide rod that inserts into the second guide cylinder is provided on the second clamping plate. The design of the sliding connecting frame and the adjustable clamping module allows this fixture to flexibly adjust the clamping position according to metal pipes of different lengths and diameters, meeting the processing needs of various pipe specifications and exhibiting good versatility.
[0008] As a further improvement of this utility model, a fixed frame is also provided on a sliding connecting frame. The fixed frame is provided with an installation groove with an opening opposite to the machined through hole. A bidirectional screw is rotatably provided in the installation groove. The two sides of the bidirectional screw are respectively screwed with mounting blocks that are slidably connected to the installation groove. The two sides of the first clamping frame are respectively provided with first connecting sleeves that are slidably connected to the two sliding connecting frames. The two sides of the second clamping frame are respectively provided with second connecting sleeves that are slidably connected to the two sliding connecting frames. A first connecting plate connected to the first connecting sleeve is provided on one mounting block, and a second connecting plate connected to the second connecting sleeve is provided on the other mounting block.
[0009] As a further improvement of this utility model, the mounting slot is also provided with a drive motor for driving the rotation of the bidirectional screw, and the drive motor is a servo motor.
[0010] As a further improvement of this utility model, a support rod is also provided between the fixed frame and the processing table.
[0011] As a further improvement of this utility model, the bottom of the processing table is also provided with support legs, and the bottom side of the support legs is also provided with an extension plate, on which anchor bolts for connecting to the ground are provided. The support legs with anchor bolts and the extension plate at the bottom of the processing table can firmly fix the entire device to the ground, effectively reducing the impact of processing vibration and ensuring operational safety.
[0012] As a further improvement of this utility model, an anti-slip pad layer is also provided on the inner wall of the support groove, a first anti-slip pad is also provided on the bottom of the first clamping plate, and a third anti-slip pad is also provided on the bottom of the second clamping plate. Through the cooperation of the support pad layer, the first anti-slip pad, and the second anti-slip pad, the pipe can be prevented from slipping, while reducing damage to the pipe surface.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, by setting a support groove with an arc-shaped inner wall at the top of the processing table, metal pipes of different diameters can be effectively positioned and supported. Combined with the first and second pressure plates with arc shapes at the bottom, the pipes are stably clamped in the vertical direction, preventing the pipes from rolling or shifting during processing, and avoiding the situation where only one side is supported while the other side is suspended, which would affect the processing effect.
[0014] Secondly, the first and second clamping modules are respectively set on both sides of the processing through hole, and their positions can be adjusted by sliding connecting brackets. This allows the pipe to be clamped and fixed on both sides of the welding and cutting position at the same time, avoiding pipe deformation or cutting deviation caused by unilateral force and improving processing accuracy.
[0015] Third, a servo motor drives a bidirectional screw to rotate, causing the two mounting blocks to move in opposite directions. This synchronously pushes the first and second clamping frames to slide along the sliding connecting frame, achieving automatic opening and closing clamping action. The operation is convenient, the response is rapid, and the work efficiency is improved.
[0016] Fourth, the design incorporates a cooperative structure between the first guide cylinder and the first guide rod, and between the second guide cylinder and the second guide rod, which enhances the rigidity and straightness of the clamping plate during lifting and lowering, prevents jamming or skewing, and ensures uniform and reliable clamping force.

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.
[0021] like Figure 1 , 2 As shown, a welding and cutting fixture for metal pipe processing includes a processing table 101. The top of the processing table 101 has a support groove 103 with an arc-shaped inner wall, provided along the left-right direction via a vertical rod 102. A processing through hole 104 is also provided on the support groove 103. Support plates 105 are also provided between the processing table 101 and the support groove 103, located on both sides of the processing through hole 104. Sliding connecting frames 106 are also provided on the processing table 101 on the front and rear sides of the support groove 103. A first clamping module is slidably mounted on one side of the two sliding connecting frames 106, and a second clamping module is slidably mounted on the other side of the two sliding connecting frames 106. A discharge through hole 107 is also provided at the bottom of the support groove 103. With the discharge through hole 107 at the bottom of the support groove 103, metal chips or slag generated during welding and cutting can fall and be discharged in a timely manner, preventing accumulation in the support groove 103 and affecting processing quality or damaging the equipment.
[0022] like Figure 1 , 4As shown, the first clamping module includes a first clamping frame 201 that is slidably connected to the sliding connecting frame 106. A first telescopic push rod 202 is vertically arranged on the first clamping frame 201. A first clamping plate 203 with an arc-shaped bottom wall is arranged at the lower end of the first telescopic push rod 202. A first guide cylinder 204 is arranged on the first clamping frame 201. A first guide rod 205 that is inserted into the first guide cylinder 204 is arranged on the first clamping plate 203.
[0023] like Figure 1 , 4 As shown, the first clamping module includes a second clamping frame 301 slidably connected to the sliding connecting frame 106. A second telescopic push rod 302 is vertically mounted on the second clamping frame 301. A second clamping plate 303 with an arc-shaped bottom wall is mounted at the lower end of the second telescopic push rod 302. A second guide sleeve 304 is mounted on the second clamping frame 301, and a second guide rod 305 that inserts into the second guide sleeve 304 is mounted on the second clamping plate 303. The design of the sliding connecting frame 106 and the adjustable clamping module allows this fixture to flexibly adjust the clamping position according to metal pipes of different lengths and diameters, meeting the processing needs of various pipe specifications and exhibiting good versatility.
[0024] like Figure 1 , 3 As shown, a sliding connecting frame 106 is also provided with a fixed frame 401. The fixed frame 401 is provided with a mounting groove 402 with an opening facing away from the machining through hole 104, which can prevent machining debris from entering the mounting groove 402. A bidirectional screw 403 is rotatably provided in the mounting groove 402. The two sides of the bidirectional screw 403 are respectively screwed with mounting blocks 404 that are slidably connected to the mounting groove 402. The two sides of the first clamping frame 201 are respectively provided with first connecting sleeves 405 that are slidably connected to the two sliding connecting frames 106. The two sides of the second clamping frame 301 are respectively provided with second connecting sleeves 406 that are slidably connected to the two sliding connecting frames 106. A first connecting plate 407 connected to the first connecting sleeve 405 is provided on one mounting block 404, and a second connecting plate 408 connected to the second connecting sleeve 406 is provided on the other mounting block 404.
[0025] like Figure 1 , 3 As shown, the mounting slot 402 is also equipped with a drive motor 409 for driving the rotation of the bidirectional screw 403. The drive motor 409 is a servo motor.
[0026] like Figure 1 , 3 As shown, a support rod 410 is also provided between the fixed frame 401 and the processing table 101. The support rod 410 can support the fixed frame 401, giving the fixed frame 401 better stability.
[0027] The metal pipe to be processed is placed in the support groove 103 on the top of the processing table 101. The inner wall of the support groove 103 is arc-shaped, which can accommodate pipes of different diameters, achieving initial positioning and support. The drive motor 409 (servo motor) is started, and the motor drives the bidirectional screw 403 to rotate in the mounting groove 402. Since the threads on both sides of the bidirectional screw 403 are opposite, the two mounting blocks 404 move synchronously in opposite directions on it. One mounting block 404 drives the first clamping frame 201 to slide along the sliding connecting frame 106 through the first connecting plate 407; the other mounting block 404 drives the second clamping frame 301 to slide along the other side of the sliding connecting frame 106 through the second connecting plate 408. In this way, the first clamping module and the second clamping module move towards each other from both sides of the processing through hole 104, approaching the part of the metal pipe to be fixed.
[0028] The first telescopic push rod 202 pushes the first pressure plate 203 with an arc-shaped bottom wall downwards, which cooperates with the support groove 103 to clamp one side of the pipe; at the same time, the second telescopic push rod 302 pushes the second pressure plate 303 with an arc-shaped bottom wall downwards to clamp the other side of the pipe; the arc-shaped pressure plate fits well with the outer wall of the pipe, ensuring stable clamping and preventing rolling or displacement during processing.
[0029] During the pressing process of the clamping plate, the first guide rod 205 slides within the first guide cylinder 204, and the second guide rod 305 slides within the second guide cylinder 304, effectively improving the rigidity and straightness of the lifting process, preventing skewing or jamming, and ensuring uniform and reliable clamping force. After the pipe is securely clamped, welding and cutting operations are performed at the machining through hole 104. Metal chips or slag generated during processing fall out and are discharged in time through the discharge through hole 107 at the bottom of the support groove 103, avoiding accumulation that could affect processing quality or damage the equipment. Furthermore, the support groove 103 and the support plate 105 can support the parts of the metal pipe corresponding to the machining through hole 104 on both sides, giving the metal pipe better stability during processing, avoiding deformation and cantilever effects, and thus better meeting people's usage needs.
[0030] After processing, the telescopic push rod retracts, lifting the clamping plate; the drive motor 409 reverses, causing the bidirectional screw 403 to drive the two mounting blocks 404 away in opposite directions, thereby pulling apart the first clamping frame 201 and the second clamping frame 301, releasing the clamping force, and making it easier to remove the finished pipe; for pipes of different lengths or diameters, the position of the clamping module on the sliding connecting frame 106 can be adjusted, and the stroke of the telescopic push rod can be adjusted to achieve flexible adaptation and meet the processing needs of multiple specifications.
[0031] According to another embodiment of the present invention, such as Figure 1As shown, the bottom of the processing table 101 is also equipped with a support leg 108, and the bottom side of the support leg 108 is also equipped with an extension plate 109. Anchor bolts 110 for connecting to the ground are provided on the extension plate 109. The support leg 108 with anchor bolts 110 and the extension plate 109 at the bottom of the processing table 101 can firmly fix the entire device to the ground, effectively reducing the impact of processing vibration and ensuring operational safety.
[0032] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, an anti-slip pad layer 501 is also provided on the inner wall of the support groove 103, a first anti-slip pad 502 is also provided on the bottom of the first clamping plate 203, and a third anti-slip pad 503 is also provided on the bottom of the second clamping plate 303. Through the cooperation of the support pad layer, the first anti-slip pad 502 and the second anti-slip pad, the pipe can be prevented from slipping, while reducing damage to the pipe surface.
[0033] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
