Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, and more specifically, to a tooling fixture for coating grooved large-diameter pipelines. Background Art

[0002] During the pipeline coating process, coating large-diameter pipelines itself poses certain challenges because of their large size, and more meticulous operations are required for surface treatment and paint coverage. Especially for the grooved parts, due to their complex structure, it is often difficult to achieve uniform spraying with traditional coating methods. Therefore, a tooling fixture for pipeline coating is needed.

[0003] However, the following deficiencies still exist in the prior art: 1. During the pipeline coating process, the coating at the contact points between the fixture and the pipeline often gets damaged, which affects the uniformity and integrity of the pipeline surface coating and results in low coating efficiency; 2. Due to the large volume and heavy weight of the pipeline, it is not convenient for operators to easily move the pipeline to the ideal position when using the fixture to fix the pipeline. This not only increases the operation difficulty but also reduces the work efficiency and practicality.

[0004] Therefore, there is an urgent need for a tooling fixture for coating grooved large-diameter pipelines to solve the above problems. Summary of the Utility Model

[0005] The purpose of the present utility model is to address the problems that currently, during the pipeline coating process, the coating at the contact points between the fixture and the pipeline often gets damaged, which affects the uniformity and integrity of the pipeline surface coating and results in low coating efficiency; due to the large volume and heavy weight of the pipeline, it is not convenient for operators to easily move the pipeline to the ideal position when using the fixture to fix the pipeline. This not only increases the operation difficulty but also reduces the work efficiency and practicality.

[0006] To achieve the above-mentioned invention purpose, the present utility model provides the following technical solutions:

[0007] A tooling fixture for coating grooved large-diameter pipelines to improve the above problems.

[0008] Specifically, this application is as follows:

[0009] A fixture for coating large-diameter grooved pipes, comprising a base and a support frame fixedly connected to the top wall of the base. A positioning ring is rotatably connected to the top wall of the support frame through a rotating groove. A positioning component for fixing the pipe is connected to the outer wall of the positioning ring. The positioning component includes a first toothed ring rotatably connected to the outer wall of the positioning ring. Uniformly distributed linkage plates are fixedly connected to the outer wall of the positioning ring. A first gear is rotatably connected to the side wall of the linkage plate. The first gear is meshed with the first toothed ring. An adjusting component is slidably connected to the inner wall of the positioning ring. A stabilizing component for improving the convenience during pipe fixing is connected to the side wall of the support frame.

[0010] As a preferred technical solution of the present application, the adjusting component includes a rack slidably connected to the inner wall of the positioning ring. A positioning bolt is fixedly connected to the side wall of the rack. The rack is meshed with the first gear. A fixing plate is fixedly connected to the outer wall of the positioning ring. A second gear is rotatably connected to the side wall of the fixing plate. A first servo motor is fixedly connected to the side wall of the fixing plate. The output end of the first servo motor is fixedly connected to the second gear. The second gear is meshed with the first toothed ring.

[0011] As a preferred technical solution of the present application, a second toothed ring is fixedly connected to the outer wall of the positioning ring. A second servo motor is fixedly connected to the side wall of the support frame. A third gear is rotatably connected to the side wall of the support frame. The output end of the second servo motor is fixedly connected to the third gear. The third gear is meshed with the second toothed ring.

[0012] As a preferred technical solution of the present application, the stabilizing component includes a stabilizing plate fixedly connected to the side wall of the support frame. A stabilizing ring is slidably connected to the inner wall of the stabilizing plate. A support wheel is rotatably connected to the top wall of the stabilizing ring.

[0013] As a preferred technical solution of the present application, an adjusting screw is rotatably connected to the bottom wall of the stabilizing ring. The adjusting screw is threadedly connected to the stabilizing plate.

[0014] In the solution of the present application:

[0015] 1. By making the positioning bolt contact the position of the bow-shaped sealing ring on the pipe, the contact area is reduced. At the same time, during the spraying process, the rotation of the positioning ring is driven by the second servo motor, thereby improving the uniformity of pipe coating, with stronger practicability. It solves the problem that in the prior art, during the pipe coating process, the coating at the contact point between the fixture and the pipe often gets damaged, thus affecting the uniformity and integrity of the pipe surface coating and resulting in low coating efficiency.

[0016] 2. By adjusting the screw rod, the pipeline can be driven to move upward through the stabilizing ring, thereby adjusting the position of the pipeline when fixing the pipeline, which is more convenient to use. This solves the problem in the prior art that due to the large volume and heavy weight of the pipeline, it is not easy for the operator to move the pipeline to the ideal position when using the fixture to fix the pipeline, which not only increases the operation difficulty but also reduces the work efficiency and practicality.

A positioning ring 102 is rotatably connected to the top wall of the support frame 101 through a rotating groove 106. A positioning member for fixing the pipe is connected to the outer wall of the positioning ring 102. The positioning member includes a first toothed ring 103 rotatably connected to the outer wall of the positioning ring 102. Uniformly distributed linkage plates 104 are fixedly connected to the outer wall of the positioning ring 102. A first gear 105 is rotatably connected to the side wall of the linkage plate 104. The first gear 105 is meshed and connected to the first toothed ring 103. An adjusting component is slidably connected to the inner wall of the positioning ring 102. A stabilizing member for improving the convenience during pipe fixing is connected to the side wall of the support frame 101. By setting the positioning ring 102 to be rotatable, the convenience during pipe coating is improved.

[0025] As Figures 1-4 shown, as a preferred embodiment, on the basis of the above method, further, the adjusting component includes a rack 110 slidably connected to the inner wall of the positioning ring 102. A positioning bolt 111 is fixedly connected to the side wall of the rack 110. The rack 110 is meshed and connected to the first gear 105. A fixing plate 113 is fixedly connected to the outer wall of the positioning ring 102. A second gear 114 is rotatably connected to the side wall of the fixing plate 113. A first servo motor 112 is fixedly connected to the side wall of the fixing plate 113. The output end of the first servo motor 112 is fixedly connected to the second gear 114. The second gear 114 is meshed and connected to the first toothed ring 103. By setting the first toothed ring 103, the rack 110 can be synchronously driven to move under the action of the first gear 105, thereby realizing the fixing of the pipe and improving the synchronism during pipe clamping.

[0026] As Figures 1-3 shown, as a preferred embodiment, on the basis of the above method, further, a second toothed ring 116 is fixedly connected to the outer wall of the positioning ring 102. A second servo motor 115 is fixedly connected to the side wall of the support frame 101. A third gear 117 is rotatably connected to the side wall of the support frame 101. The output end of the second servo motor 115 is fixedly connected to the third gear 117. The third gear 117 is meshed and connected to the second toothed ring 116. The automation efficiency during pipe coating is improved under the action of the second toothed ring 116.

[0027] As Figures 1-2 shown, as a preferred embodiment, on the basis of the above method, further, the stabilizing member includes a stabilizing plate 120 fixedly connected to the side wall of the support frame 101. A stabilizing ring 121 is slidably connected to the inner wall of the stabilizing plate 120. A support wheel 122 is rotatably connected to the top wall of the stabilizing ring 121.

[0029] Specifically, when using this kind of tooling fixture for coating large-diameter grooved pipes: First, place both ends of the pipe onto the positioning ring 102, and then rotate the adjusting screw 123 to drive the stabilizing ring 121 to move upward. By driving the pipe to move upward through the stabilizing ring 121, the pipe can be adjusted to the central position of the positioning ring 102, which is convenient for improving the convenience of pipe positioning. Then, start the first servo motor 112 to drive the second gear 114 to rotate. By driving the first toothed ring 103 to rotate through the second gear 114, when the first toothed ring 103 rotates, it simultaneously drives the four groups of racks 110 to move inward into the positioning ring 102, and contacts the position of the mounting bow-shaped sealing ring on the pipe through the positioning bolt 111, thereby realizing the fixation of the pipe. Then, during the spraying process of the pipe, start the second servo motor 115 to drive the third gear 117 to rotate. By meshing the third gear 117 with the second toothed ring 116, the rotation of the positioning ring 102 is realized, so that the uniformity of the pipe spraying can be achieved. And because the volume of the positioning bolt 111 is small, it can improve the convenience of repairing the repair point, and the practicability is stronger.
