Description

Technical Field

[0001] The utility model relates to the technical field of pipe joint processing, in particular to a pipe joint positioning device. Background Art

[0002] A pipe joint is a device that connects two pipes and is used to make the pipes connect tightly and firmly. Pipe joints are usually made of metal, plastic or other materials, and have different models and specifications. Appropriate pipe joints can be selected according to the requirements of the pipeline. Pipe joints can be divided into different types such as welding type, threaded type, flange type, etc., and are commonly used in industrial pipeline systems, plumbing systems and other fields. Pipe joints have the characteristics of easy installation, reliable sealing, and high pressure resistance. They are important connectors in pipeline systems. When testing and processing pipe joints, positioning devices are required. The function of the positioning device is to clamp and fix the pipe joints. Since most pipe joints are in the shape of a ring, it is necessary to arrange clamping blocks around the pipe joints, and operate them one by one to clamp the pipe joints. The positioning efficiency is slow, so the inventor proposes a pipe joint positioning device. Utility Model Content

[0027] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a pipe joint positioning device, including a fixing frame 1, a support plate 6, and a clamping disk 5. A driving motor 2 is fixed to the back of the fixing frame 1, and the support plate 6 is installed on a side of the fixing frame 1 away from the driving motor 2, and the support plate 6 is rotatably connected to the fixing frame 1; a clamping ring 7 is rotatably installed on the inner side of the support plate 6, and a clamping block 8 is protruding on the inner circular surface of the clamping ring 7, and the upper surface of the clamping ring 7 is recessed and has a mounting groove 12, and a clamping disk 5 is rotatably installed in the mounting groove 12, and the inner wall of the clamping disk 5 fits the end of the clamping block 8, and the clamping block 8 can move through the clamping ring 7, and the upper surface of the clamping disk 5 is connected to a vertically arranged driving rod 4; a connecting block 10 is protruding on the surface of the support plate 6 facing the fixing frame 1, and a rotating gear 18 is rotatably installed inside the connecting block 10. Rotating teeth 9 are distributed around the outer wall of the clamping ring 7 , and the rotating teeth 9 are adapted to the rotating gear 18 . The adjusting shaft 3 is fixedly installed on the center surface of the rotating gear 18 , and the adjusting shaft 3 rotates vertically and passes through the connecting block 10 .

[0028] Reference Figure 2 , Figure 3 A driving block 13 is protruding from the bottom of the clamping disk 5. The driving block 13 contacts the portion of the clamping block 8 located in the mounting groove 12. A driving rod 4 is fixed to the upper surface of the clamping disk 5. The clamping disk 5 is threadedly connected to the mounting groove 12.

[0029] Reference Figure 4A fixing tube 14 is also fixedly mounted on the side wall of the connecting block 10, and an operating rod 16 is horizontally passed through the interior of the fixing tube 14. A spring 15 is sleeved on the part of the operating rod 16 located outside the fixing tube 14. One end of the spring 15 is fixedly connected to the outer wall of the operating rod 16, and the other end is fixedly connected to a fixing block 19, and the fixing block 19 is fixedly connected to the inner wall of the fixing tube 14.

[0030] The working principle provided by the utility model is that when in use, the pipe joint is first placed in the clamping ring 7, and then the driving rod 4 is rotated, and the driving rod 4 drives the clamping plate 5 to descend along the thread of the installation groove 12. During the rotation of the clamping plate 5, the driving block 13 at the bottom rotates synchronously, and the driving block 13 rotates and contacts with the clamping block 8. The clamping block 8 is forced to move toward the center position of the clamping ring 7 to clamp the outer wall of the pipe joint. At this time, the pipe joint can be fixed in the center of the clamping ring 7. Only one step is required to rotate the clamping plate 5 to drive the four groups of clamping blocks 8 to move synchronously to clamp the pipe joint. The operation is simple and the steps are convenient. After the pipe joint is clamped, its surface or inner hole can be overhead tested. If it needs to be turned over, the driving motor 2 is started, and the driving motor 2 drives the support plate 6 to turn over. During the turning process of the support plate 6, the pipe joint rotates to adjust the upward processing surface;

[0031] At the same time, the pipe joint can also rotate in the plane within the support plate 6. First, pull the operating rod 16 to drive the limit head 17 to leave the tooth gap of the rotating gear 18, and then rotate the adjusting shaft 3. The adjusting shaft 3 drives the driving gear to rotate, and the rotating teeth 9 meshing with the driving gear drive the clamping ring 7 to rotate as a whole, and then the pipe joint clamped on the inner side of the clamping ring 7 starts to rotate in the plane. Release the pull on the operating rod 16, and the spring 15 resets and pulls the operating rod 16 toward the connecting block 10, so that the limit block is again plugged into the tooth gap of the outer wall of the rotating gear 18.
