Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Fig. 1 is a partial cross-sectional view of a clamping device according to an embodiment of the present invention in a use state. FIG. 2 is a positioning assembly of the fixture apparatus shown in FIG. 1. As shown in fig. 1 and 2, the clamp device 100 is used for restraining a pipe assembly including a first pipe member 30 and a second pipe member 40 butted or inserted thereto. The clamping device 100 includes a bracket 1 and a clamping unit 2. Wherein the clamping unit 2 comprises a positioning assembly 21 and a righting assembly 22, the positioning assembly 21 being arranged on a worktable of the welding machine for receiving and positioning the first tubular element 30. The righting assembly 22 is disposed on the welding machine platform by the carriage 1 and is separate from the positioning assembly 21, and is capable of receiving or gripping the second tubular 40 and abutting or plugging it with the first tubular 30. Wherein, the pipe assembly includes but is not limited to air conditioner inlet pipe assembly. When the pipe assembly is selected as an air conditioner liquid inlet pipe assembly, the first pipe 30 is a pipe joint, and the second pipe 40 is a copper pipe connected with the pipe joint.

Therefore, the clamping device 100 can reduce the number of operators required for welding operation, reduce the labor intensity of workers, and meanwhile help to reduce the risk of scalding the operators in the welding process.
In the present embodiment, the positioning assembly 21 includes a plug portion 211 and an associated base portion 212. Wherein the plug portion 211 can be inserted into the end of the first pipe member 30 and prevent the first pipe member 30 from shaking. The base 212 is disposed outside the first tube 30 and can hold the first tube 30. When the first pipe 30 is selected as the pipe joint, since the plug portion 211 avoids the external thread of the pipe joint and positions the pipe joint in a manner of being inserted into the inside of the pipe joint, the clamp device 100 of the embodiment of the present invention can also play a role of avoiding damage to the external thread of the pipe joint. Preferably, the clearance between the plug of the positioning assembly 21 and the end of the first pipe 30 is less than 0.2mm, so as to prevent the first pipe 30 from shaking during welding, and to improve the welding quality. The material of the positioning component 21 is preferably 304 stainless steel with good processing performance and high toughness.
In this embodiment, the positioning assembly 21 further includes an air intake chamber 213 disposed within the plug portion 211 and the base portion 212. The gas inlet chamber 213 is used to receive an inert gas, such as nitrogen, which can be introduced into the first and second pipe members 30 and 40 in sequence, thereby preventing the inner walls of the first and second pipe members 30 and 40 from being oxidized during the welding process.

When the second pipe 40 abuts against the base plate 226, the elastic support assembly 225 can urge the first end of the first clamping bar 222 and the first end of the second clamping bar 224 away from each other by its own elastic force, urge the second end of the first clamping bar 222 and the second end of the second clamping bar 224 to approach each other and clamp the second pipe 40 abutting against the base plate 226, so that the second pipe 40 can be clamped and the second pipe 40 can be forced to abut against or be inserted into the first pipe 30.
Preferably, the material of the first clamping bar 222 and the second clamping bar 224 is selected from 304 stainless steel with good processability and high toughness. The material of the base plate 226 is preferably Q235A carbon steel having good weldability and hot workability.
In this embodiment, the centralizer assembly 22 further comprises a stop member 227 disposed on the base 226 between the first and second clamping bars 222, 224. The stopping member 227 is closer to the second end portion than the first rotating shaft 221 and the second rotating shaft 223, and can define the shortest distance between the second end portion of the first clamping bar 222 and the second end portion of the second clamping bar 224. Preferably, the shortest distance is less than the diameter of the second tubular 40, reducing the risk of pinching the second tubular 40 while ensuring that the centralizer assembly 22 can exert a secure restraint on the second tubular 40. The stopping member 227 may be a rectangular block or a polygonal block, but is preferably a cylinder that is not prone to damage the first clamping bar 222 and the second clamping bar 224. Preferably, a first arc surface 222a and a second arc surface 224a are respectively provided on the second end of the first clamping bar 222 and the second end of the second clamping bar 224, wherein the first arc surface 222a and the second arc surface 224a are splayed, so that the second pipe 40 can be easily inserted between the first clamping bar 222 and the second clamping bar 224.
In this embodiment, the resilient support assembly 225 includes a compression spring 225a disposed between a first end of the first clamping bar 222 and a first end of the second clamping bar 224, and a first bolt 225b capable of being threaded laterally out of the first clamping bar 222 and into one end of the compression spring 225a and a second bolt 225c capable of being threaded laterally out of the second clamping bar 224 and into the other end of the compression spring 225 a. The compression spring 225a is captured between the first end of the first clamp bar 222 and the first end of the second clamp bar 224 by the first bolt 225b and the second bolt 225c and is compressed by or urges the first end of the first clamp bar 222 and the first end of the second clamp bar 224 toward each other. In this embodiment, as shown in fig. 3 and 4, the clamping device 100 further includes a third bolt 228 penetrating through the base 226 and fixing the base to the bracket 1, and the through hole provided in the base 226 for receiving the third bolt 228 is a strip hole 226a, which can allow the third bolt 228 with the centering assembly 22 to slide along the strip hole 226a, so as to adjust the position of the second tubular member 40, so that the second tubular member 40 can be butted or inserted with the first tubular member 30.
