Description

Technical Field

[0001] This utility model relates to the field of auxiliary technology for pipeline welding, specifically a clamping device for welding HVAC pipelines. Background Technology

[0002] In the construction of HVAC engineering, pipe welding is an extremely important step. The quality of HVAC pipe connections directly affects the operational stability and safety of the entire HVAC system.

[0003] Current HVAC pipe welding methods largely rely on manual support for pipe positioning, which is not only labor-intensive but also makes it difficult to ensure the accuracy of pipe connections. This can easily lead to problems such as pipe centerline misalignment and uneven gaps, resulting in poor welding quality and potential air and water leaks. Although some pipe clamping devices are available on the market, most are complex in structure, lack versatility, and are only suitable for pipes of specific diameters. They cannot meet the welding needs of various pipe diameters in HVAC projects. In addition, some clamping devices are cumbersome and time-consuming to adjust, reducing construction efficiency and failing to meet current requirements. Utility Model Content

The rotating structure is disposed on the top of the base, and the clamping structure is disposed on the side of the rotating structure. A frame is fixedly installed on the top of the base, and an electric push rod is fixedly installed on the top of the frame. A welding component is fixedly installed on the moving end of the electric push rod.

[0006] The rotating structure consists of a U-shaped frame, a rotating shaft, a first motor, a first pulley, a fixing block, a circular ring, a second pulley, and a belt. The U-shaped frame is fixedly installed on the top of the base, the rotating shaft is rotatably installed inside the U-shaped frame, the first motor is fixedly installed on the side of the U-shaped frame, the first pulley is fixedly installed on the surface of the rotating shaft, the fixing block is fixedly installed on the top of the base, the circular ring is rotatably installed inside the fixing block, the second pulley is fixedly installed on the surface of the circular ring, and the belt is sleeved on the surface of the second pulley.

[0007] Preferably, the clamping structure consists of a mounting block, a sliding rod, a bidirectional threaded rod, a clamping plate, and a second motor.

[0008] Preferably, the output shaft and the rotating shaft of the first motor are fixedly connected. After the first motor is powered on, its internal stator winding will generate a rotating magnetic field. The rotor will be subjected to Ampere force due to the induced current, and thus begin to rotate. As the output part of the first motor, the output shaft will rotate synchronously with the rotor, which can drive the rotating shaft to rotate around its own axis.

[0009] Preferably, the first pulley and the second pulley are connected by a belt drive, and the ring can be rotated by rotating the shaft under the action of the first pulley, the second pulley, and the belt.

[0010] Preferably, both the ring and the mounting block are provided with ball bearings, which facilitates the sliding of the HVAC pipes within the ring and the mounting block.

[0011] Preferably, the clamping plate is slidably mounted on the surface of the slide rod, and the surface of the clamping plate is provided with an anti-slip layer. By rotating the bidirectional threaded rod, the clamping plate can be moved under the guidance of the slide rod. The anti-slip layer can increase the friction between the clamping plate and the HVAC pipe.

[0012] Preferably, the output shaft of the second motor and the bidirectional threaded rod are fixedly connected. After the second motor is powered on, its internal stator winding will generate a rotating magnetic field. The rotor will be subjected to Ampere force due to the induced current, and thus begin to rotate. As the output part of the second motor, the output shaft will rotate synchronously with the rotor, which can drive the bidirectional threaded rod to rotate around its own axis.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the special clamping device for welding HVAC pipes can move the clamping plate to clamp and fix two HVAC pipes by starting the second motor, and start the first motor to make the ring rotate, which can drive the mounting block to rotate, thereby making the two HVAC pipes rotate synchronously, which facilitates welding the two HVAC pipes together and has a good effect.

A frame 4 is fixedly installed on the top of the base 1, and an electric push rod 5 is fixedly installed on the top of the frame 4. A welding component 6 is fixedly installed on the moving end of the electric push rod 5.

[0021] The rotating structure 2 consists of a U-shaped frame 201, a rotating shaft 202, a first motor 203, a first pulley 204, a fixing block 205, a ring 206, a second pulley 207, and a belt 208.

The first motor 203 is fixedly installed on the side of the U-shaped frame 201. The output shaft of the first motor 203 is fixedly connected to the rotating shaft 202. After the first motor 203 is powered on, its internal stator windings will generate a rotating magnetic field. The rotor will experience an Ampere force due to the induced current, thus starting to rotate. This serves as the output of the first motor 203. The output shaft rotates synchronously with the rotor, which can drive the rotating shaft 202 to rotate around its own axis. The first pulley 204 is fixedly installed on the surface of the rotating shaft 202, the fixing block 205 is fixedly installed on the top of the base 1, the ring 206 is rotatably installed inside the fixing block 205, the second pulley 207 is fixedly installed on the surface of the ring 206, and the belt 208 is sleeved on the surface of the second pulley 207.

By rotating the rotating shaft 202, the ring 206 can be rotated under the action of the first pulley 204, the second pulley 207, and the belt 208.

[0022] The clamping structure 3 consists of a mounting block 301, a sliding rod 302, a bidirectional threaded rod 303, a clamping plate 304, and a second motor 305. The mounting block 301 is fixedly mounted on the side of the ring 206. Both the ring 206 and the mounting block 301 are equipped with ball bearings, which facilitates the sliding of HVAC pipes within the ring 206 and the mounting block 301. The sliding rod 302 is fixedly mounted inside the mounting block 301. The bidirectional threaded rod 303 is rotatably mounted inside the mounting block 301. The clamping plate 304 is threaded onto the surface of the bidirectional threaded rod 303 and slidably mounted on the surface of the sliding rod 302. The surface of the clamping plate 304 is provided with… The anti-slip layer allows the clamping plate 304 to move under the guidance of the slide rod 302 by rotating the bidirectional threaded rod 303. The anti-slip layer increases the friction between the clamping plate 304 and the HVAC pipes. The second motor 305 is fixedly installed on the side of the mounting block 301. The output shaft of the second motor 305 is fixedly connected to the bidirectional threaded rod 303. After the second motor 305 is powered on, its internal stator winding will generate a rotating magnetic field. The rotor will be subjected to Ampere force due to the induced current, and thus start to rotate.

The two HVAC pipes are moved so that their ends are connected and positioned below the welding assembly 6. The second motor 305 is started to rotate the bidirectional threaded rod 303.

The electric push rod 5 is started to move the welding assembly 6 to the ends of the two HVAC pipes. The first motor 203 is started to rotate the rotating shaft 202. Under the action of the first pulley 204, the second pulley 207, and the belt 208, the ring 206 can rotate, which can drive the mounting block 301 to rotate, thereby making the two HVAC pipes rotate synchronously. The two HVAC pipes can then be welded together by the welding assembly 6.
