Technical Field

[0001] The present application relates to the technical field of pipeline welding, for example, to a positioning device for process pipe welding. Background Art

[0002] The related art (Announcement No.: CN218657573U) discloses a welding machine for process pipes, including a welding table, a centering combined drive mechanism is arranged inside the welding table, a support cylinder is arranged on the top of the centering combined drive mechanism, a welding height control mechanism is arranged inside the support cylinder, a clamping table is arranged on the top of the welding height control mechanism, and a process pipe clamping assembly is arranged on the surface of the clamping table. The purpose of adjusting the welding height is achieved, and the use needs of different welders can be met.

[0003] In the process of implementing the above embodiments, it is found that there are at least the following problems in the related art:

[0004] The assembly welding machine of the process pipe can clamp the process pipe body to prevent the process pipe body from shaking through the design of the process pipe clamping assembly. Then, through the design of the centering combined drive mechanism, the two support cylinders can be driven to approach each other, driving the ends of the process pipe body to contact each other, so as to perform welding.

[0010] Optionally, it also includes: a sleeve connected to one of the first support plate and the second support plate; a first optical axis connected to the other of the first support plate and the second support plate, and slidably installed inside the sleeve; wherein the movement direction of the first optical axis relative to the sleeve is the same as the movement direction of the moving end of the electric push rod.

[0011] Optionally, it also includes: a first linear bearing installed between the sleeve and the first optical axis.

[0012] Optionally, it further includes: a base, which is respectively installed at the four corners of the second support plate; wherein, along the thickness direction of the second support plate, the base and the electric push rod are located on both sides of the second support plate.

[0016] Optionally, each of the clamping blocks comprises: a V-shaped groove, and the V-shaped grooves of two clamping blocks that are arranged opposite to each other are arranged opposite to each other.

[0017] The present disclosure provides a positioning device for process pipe welding, which can achieve the following technical effects:

[0018] A positioning device for process pipe welding provided by an embodiment of the present disclosure includes a first support plate, a linear slide, a rectangular frame, a cushion block, a thumb cylinder, a clamping arm, a spring and a clamping block. The linear slide is installed on the second support plate along the length direction of the first support plate to realize the linear motion function. The rectangular frame is movably mounted on the first support plate and installed on the moving end of the linear slide, and moves along the length direction of the first support plate under the drive of the linear slide. The cushion block is installed on the first support plate to play the role of supporting and raising. Along the length direction of the first support plate, the cushion block and the rectangular frame are located on both sides of the first support plate, and the cushion blocks and rectangular frames on both sides are respectively used to support and install the thumb cylinder. The thumb cylinders are respectively installed on the cushion block and the rectangular frame, and are both used to clamp the process pipe. The clamping arms are respectively installed on each moving end of each thumb cylinder, and are respectively used to support and install the springs. The clamping arms connected to the two moving ends of the same thumb cylinder are relatively distributed so that the two springs on the two relatively distributed clamping arms can be distributed directly opposite to each other. The springs are respectively connected to each clamping arm, and are respectively used to provide elastic force. The springs on the two clamping arms that are arranged opposite to each other are arranged opposite to each other, so that the two clamping blocks on the two springs that are arranged opposite to each other are arranged opposite to each other. The clamping blocks are respectively connected to each spring and are respectively used to abut against the outer wall of the process pipe. The clamping blocks on the two springs that are arranged opposite to each other are arranged opposite to each other so as to clamp the process pipe.

[0019] During use, the cylinders on both sides are controlled to work respectively, so that the two clamping arms on both sides can be driven to move toward each other. Driven by the two springs on both sides, the two clamping blocks on both sides can be moved toward each other. When the two clamping blocks on both sides are against the outer walls of the process tubes on both sides, the two springs on both sides can be compressed, thereby providing elastic force to clamp and fix the process tubes on both sides. Then the linear slide is controlled to work, so that the rectangular frame can be driven to approach the pad until the process tubes on both sides are against each other. At this time, the contact points of the process tubes on both sides can be welded. In addition, during the welding process, since the two springs on both sides can be compressed, the circumferential position of the process tubes on both sides can be adjusted by manually rotating them, so as to facilitate welding of the entire circumferential surface of the process tube. At the same time, the design of the linear slide and the thumb cylinder located on both sides of the first support plate along the thickness direction of the first support plate can prevent welding slag from falling directly on the surface of the linear slide, thereby causing the linear slide to get stuck.

The linear slide 2 is installed on the first support plate 1 along the length direction of the first support plate 1. The rectangular frame 3 is movably mounted on the first support plate 1 and is installed on the moving end of the linear slide 2. The cushion block 4 is installed on the first support plate 1, and along the length direction of the first support plate 1, the cushion block 4 and the rectangular frame 3 are located on both sides of the first support plate 1. The thumb cylinder 5 is installed on the cushion block 4 and the rectangular frame 3 respectively. The clamping arm 6 is installed on each moving end of each thumb cylinder 5 respectively, and the clamping arms 6 connected to the two moving ends of the same thumb cylinder 5 are relatively distributed. The spring 7 is connected to each clamping arm 6 respectively, and the springs 7 on the two clamping arms 6 that are relatively distributed are arranged oppositely. The clamping block 8 is connected to each spring 7 respectively, and the clamping blocks 8 on the two springs 7 that are arranged oppositely are arranged oppositely. Among them, along the thickness direction of the first support plate 1 , the linear slide 2 and the thumb cylinder 5 are located on both sides of the first support plate 1 .

[0037] A positioning device for process pipe welding provided by an embodiment of the present disclosure includes a first support plate 1, a linear slide 2, a rectangular frame 3, a cushion block 4, a thumb cylinder 5, a clamping arm 6, a spring 7 and a clamping block 8. The linear slide 2 is installed on the first support plate 1 along the length direction of the first support plate 1 to realize the linear motion function. The rectangular frame 3 is movably mounted on the first support plate 1 and installed on the moving end of the linear slide 2. It moves along the length direction of the first support plate 1 under the drive of the linear slide 2. The cushion block 4 is installed on the first support plate 1 to play a supporting and cushioning role. Along the length direction of the first support plate 1, the cushion block 4 and the rectangular frame 3 are located on both sides of the first support plate 1, and the cushion blocks 4 and the rectangular frame 3 on both sides are respectively used to support and install the thumb cylinder 5. The thumb cylinder 5 is respectively installed on the cushion block 4 and the rectangular frame 3, and both are used to clamp the process pipe. The clamping arm 6 is respectively installed on each moving end of each thumb cylinder 5, and is respectively used to support and install the spring 7. The clamping arms 6 connected to the two moving ends of the same thumb cylinder 5 are relatively distributed so that the two springs 7 on the two relatively distributed clamping arms 6 can be arranged oppositely. The springs 7 are respectively connected to each clamping arm 6 and are respectively used to provide elastic force. The springs 7 on the two relatively distributed clamping arms 6 are arranged oppositely so that the two clamping blocks 8 on the two oppositely distributed springs 7 are arranged oppositely. The clamping blocks 8 are respectively connected to each spring 7 and are respectively used to abut against the outer wall of the process pipe. The clamping blocks 8 on the two oppositely distributed springs 7 are arranged oppositely so as to clamp the process pipe.

[0038] During use, the cylinders on both sides are controlled to work respectively, so that the two clamping arms 6 on both sides can be driven to move toward each other. Driven by the two springs 7 on both sides, the two clamping blocks 8 on both sides can be moved toward each other. When the two clamping blocks 8 on both sides are against the outer walls of the process tubes on both sides, the two springs 7 on both sides can be compressed, thereby providing elastic force to clamp and fix the process tubes on both sides. Then the linear slide 2 is controlled to work, so that the rectangular frame 3 can be driven to approach the pad 4 until the process tubes on both sides are against each other. At this time, the contact points of the process tubes on both sides can be welded. In addition, during the welding process, since the two springs 7 on both sides can be compressed, the circumferential position can be adjusted by manually rotating the process tubes on both sides, so as to facilitate welding of the entire circumferential surface of the process tube. At the same time, the design that the linear slide 2 and the thumb cylinder 5 are located on both sides of the first support plate 1 along the thickness direction of the first support plate 1 can prevent welding slag from falling directly on the surface of the linear slide 2, thereby causing the linear slide 2 to get stuck.
