Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a pipeline welding clamp. Background Art

[0002] Pipeline welding is mostly used for welding between metal pipes, such as stainless steel pipes, which are mostly used for the transportation of liquids or gases. Multiple pipes are welded together to form a long pipe to meet the needs of use. Pipeline welding will inevitably use clamps. Pipeline welding clamps are used to ensure the correct alignment, fixation and support of the pipes, thereby ensuring the quality of the welding.

[0003] At present, the fixtures used for pipe welding mostly place the pipe in a clamping ring, and now welding is mostly automated, so the pipe will be inserted into the interior of the welding equipment. The welding equipment is in a ring shape, and all-round welding of the pipe is achieved by controlling the rotation of the welding head.

[0004] The above method can clamp the pipeline, but the above clamping method is to clamp the pipe body, extend the pipeline into the clamping ring, and clamp the pipeline through the control mechanism on the clamping ring. The control mechanism is also mostly manually operated to clamp the pipeline, such as controlling the rotation of the bolt to drive the clamping block to move, so as to achieve stable clamping of the pipeline. However, this method is cumbersome to install and disassemble, wastes time, and reduces work efficiency. Therefore, we propose a pipeline welding clamp to solve the above problems.

[0029] Example

[0030] Reference Figure 1-Figure 7 The utility model provides a technical solution: a pipeline welding fixture, including a processing plate 1 and a fixture mechanism 3, a moving block 2 is slidably installed on the upper surface of the processing plate 1, the fixture mechanism 3 includes a clamping block 31, the clamping block 31 is fixedly installed on the upper surface of the processing plate 1, the inner part of the clamping block 31 is slidably connected to the clamping plate 311, a sliding groove 321 is provided on the upper surface of the processing plate 1, the inner wall of the sliding groove 321 is fixedly connected to a supporting spring 32, one end of the supporting spring 32 is fixedly connected to a sliding block 322, one side of the sliding block 322 is fixedly connected to the moving block 2, and a limiting plate 33 is slidably installed on one side of the moving block 2.

[0031] In a preferred embodiment, a through hole 4 is provided on one side of the moving block 2, and the through hole 4 passes through the interior of the moving block 2. A sliding cylinder 5 is fixedly connected to one side of the moving block 2, and the interior of the sliding cylinder 5 is slidably connected to a limiting plate 33. To facilitate the installation and removal of the pipeline, the present device is provided with a through hole 4 inside the moving block 2. The pipeline can slide into the interior of the clamping block 31 through the interior of the through hole 4, and under the action of the limiting plate 33, the pipeline is limited so that the pipeline can be processed stably. Similarly, the limiting plate 33 is controlled to move to open the through hole 4, so that the processed pipeline can be removed from the interior of the moving block 2 for easy operation.

[0032] In a preferred embodiment, the inner wall of the sliding cylinder 5 is fixedly connected to the sliding rod 6, a sliding groove 7 is opened on one side of the limit plate 33, and the inner wall of one side of the sliding groove 7 is fixedly connected to the limit spring 8. One end of the limit spring 8 is fixedly connected to the sliding rod 6. In order to ensure the stable movement of the limit plate 33, the sliding rod 6 is installed on the inner wall of the sliding cylinder 5, and a sliding groove 7 is opened on one side of the limit plate 33. The sliding rod 6 moves inside the sliding groove 7, and moves out to control the stable movement of the limit plate 33, thereby realizing the limitation of the pipeline.

[0033] In a preferred embodiment, the internal rotation of the clamping block 31 is connected to the annular block 16, and a circular groove 9 is provided on the inner side of the annular block 16. The inner bottom of the circular groove 9 is fixedly connected to the clamping spring 10. One end of the clamping spring 10 is fixedly connected to the clamping plate 311, and one side of the clamping plate 311 is fixedly connected to the rubber pad. This device extends the pipeline into the interior of the clamping block 31. In order to improve the clamping effect of the pipeline, the clamping spring 10 and the clamping plate 311 are installed inside the clamping block 31. By using the clamping plate 311 and the clamping spring 10 in combination, the pipeline can be stably clamped and limited.

[0034] In order to facilitate the welding of pipelines, the device has a positioning frame 11 fixedly installed on the upper surface of the processing plate 1, a welding robot arm 12 is installed on the inner side of the positioning frame 11, and a welding head 13 is installed at one end of the welding robot arm 12. The movement of the welding head 13 is controlled by the welding robot arm 12, so that the welding head 13 can be conveniently controlled to weld the pipeline at various required angles to meet the needs of use.

[0035] The opposite ends of the two pipes are fitted together. In order to facilitate the complete welding of the connection, a driving mechanism 14 is installed on the processing plate 1. The driving mechanism 14 includes a driving motor 141, a driving block 142 and a rubber tube 143. The driving motor 141 is fixedly installed on the upper surface of the processing plate 1, and the output end of the driving motor 141 is fixedly connected to the transmission shaft 15, one end of the transmission shaft 15 is fixed to the driving block 142, and the rubber tube 143 is fixedly installed on one side of the annular block 16. The outer surfaces of the rubber tube 143 and the driving block 142 are respectively fixedly connected to a plurality of protrusions 17, and are evenly arranged on the outer surfaces of the rubber tube 143 and the driving block 142. In actual use, by installing the rubber tube 143 on one side of the annular block 16 and installing the driving motor 141 on the upper surface of the processing plate 1, the driving motor 141 controls the driving block 142 to rotate, and drives the rubber tube 143 to rotate, so as to drive the pipeline to rotate, thereby fully welding the welding part of the pipeline and improving the welding effect. Moreover, the welding part is exposed to the outside, which is convenient for observing the welding effect and convenient for use.

[0036] Specifically, the working process or working principle of a pipeline welding clamp is as follows: currently, the clamps used for pipeline welding mostly place the pipeline in a clamping ring, and now welding is mostly automated, so the pipeline will be inserted into the interior of the welding equipment. The welding equipment is in a ring shape, and by controlling the rotation of the welding head 13, all-round welding of the pipeline is achieved.

[0037] The above method can clamp the pipeline, but the above clamping method is to clamp the pipe body, extend the pipeline into the clamping ring, and clamp the pipeline through the control mechanism on the clamping ring. The control mechanism is also mostly manually operated to clamp the pipeline, for example, controlling the rotation of the bolt to drive the clamping block 31 to move, so as to achieve stable clamping of the pipeline. However, this method is cumbersome to install and disassemble, wastes time, and reduces work efficiency. Therefore, the present device is designed to solve this problem. An external power supply is connected, and the pipeline to be welded is installed inside the clamping block 31. Since the pipeline before welding is shorter, during installation, the moving block 2 is first pulled to lengthen the distance between the moving block 2 and the clamping block 31, and then one end of the pipeline is first against one side of the limit plate 33, and then the other end of the pipeline is aligned with the center of the clamping block 31, and the end is inserted into the inside of the clamping block 31. At this time, the clamping plate 311 will clamp and limit the pipeline under the action of the clamping spring 10.

[0038] At the same time, another pipe is installed inside the clamping block 31 according to the above method, and the opposite ends of the two pipes are fitted together. Under the action of the support spring 32, the limit plate 33 on the moving block 2 is stably pressed against one end of the pipe to limit the opposite end faces of the two pipes, and then the welding robot 12 can be controlled to work, and the working welding head 13 can weld the connection of the pipe.

[0039] In actual use, it is necessary to weld a circle of the pipe connection, so while welding the pipe, the drive motor 141 can be turned on, and the transmission shaft 15 can be driven to rotate by the drive motor 141. In order to reduce the rotation speed, the device installs a reducer at the output end of the drive motor 141, and controls the transmission shaft 15 to rotate slowly through the reducer, thereby driving the drive block 142 to rotate, and the protrusion 17 on the drive block 142 pushes the protrusion 17 on the outer surface of the rubber tube 143 to move, so that the drive block 142 can drive the rubber tube 143 to rotate, and the pipe runs through the inside of the rubber tube 143. The rubber tube 143 has a certain toughness and can fit tightly against the outer surface of the pipe, thereby driving the pipe to rotate, realizing comprehensive welding of the connection position of the pipe and improving the welding effect.

[0040] After welding is completed, the two pipes are combined into one pipe. At this time, the limit plate 33 is pulled to move, one end of the moving block 2 is opened, and then the pipe is directly pulled out from the inside of the moving block 2, thereby removing the processed pipe.

[0041] It should be noted that the welding robot arm 12 and the drive motor 141 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
