Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pipe joint grinding, and in particular relates to a pipe joint corner grinding device. Background Art
[0002] A pipe fitting is a component used to connect two or more parts of a pipe. It usually includes an internal thread and an external thread, which can be connected and disconnected by rotating. Pipe fittings come in a variety of shapes and types, including straight fittings, elbow fittings, tee fittings, etc., and the appropriate type can be selected for use as needed. Pipe fittings are usually made of metal, plastic or other durable materials to ensure the firmness and sealing of the pipe connection. When the pipe fittings are actually installed on site, the edges and corners of the pipe fittings need to be polished during installation to facilitate a tighter connection between the pipes. However, most of the current polishing equipment is handheld, requiring one hand to hold the polishing gun and the other hand to hold the pipe fitting. When the polishing gun contacts the pipe fitting, the stability of the single-handed holding is poor, and the single-handed adjustment angle range is limited during polishing, which is not convenient for changing the polishing position. Therefore, the inventor proposes a pipe fitting edge polishing device. Utility Model Content

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] This specific implementation method is a pipe joint corner grinding device, and its structural schematic diagram is as follows Figure 1As shown, it includes a carrying plate 1, a protection box 2, and a swing rod 3. The carrying plate 1 is horizontally arranged, and two groups of protection boxes 2 are slidingly symmetrically arranged on the upper surface of the carrying plate 1.
[0024] Reference Figure 2 A driving column 6 is fixedly installed in the center of the upper surface of the supporting plate 1, and a grinding rod 4 and a grinding wheel 8 are installed at intervals on the outer surface of the driving column 6. Motors for driving the grinding rod 4 and the grinding wheel 8 to rotate are installed inside the driving column 6.
[0025] Reference Figure 3 The top side wall of the swing rod 3 is fixedly connected with a rotating shaft 9, which rotates through the carrier plate 1. The rotating shaft 9 passes through the outer wall of the carrier plate 1 and is fixed with a follower block 11, which is perpendicular to the swing rod 3. The interior of the follower block 11 slides through a limit rod 12, which is fixedly plugged with the outer wall of the carrier plate 1.
[0026] Reference Figure 4 The upper surfaces of the two groups of protection boxes 2 are respectively provided with a first handle 5 and a second handle 7, which are adapted to fit each other. A limited rotation block 10 is rotatably installed on the side wall of the carrier plate 1, and the limited rotation block 10 rotates to fit the side wall of the protection box 2. A swing rod 3 is rotatably installed on the bottom of the carrier plate 1, and the swing rod 3 is symmetrically distributed along the four corners of the carrier plate 1. A U-shaped clamping block 14 is fixed on the side wall of the first handle 5, and a screw 15 is threadedly installed on the side wall of the clamping block 14. A rotating disk 16 is rotatably installed on the side wall of the second handle 7, and a fixing rod 13 is fixedly connected to the outer circumferential surface of the rotating disk 16. The fixing rod rotates toward the inner side of the clamping block 14, and a fixing hole is provided on the outer wall of the fixing rod 13, and the fixing hole is threadably adapted to the screw 15.
[0027] Working principle: when in use, first flip the swing arm 3 from the bottom of the carrier plate 1 and unfold it. The swing arm 3 originally fits the bottom of the carrier plate 1. After flipping, it rotates from a horizontal state to a vertical state. The rotating shaft 9 rotates synchronously with the swing arm 3, and the follower block 11 on the outer wall of the rotating shaft 9 also rotates accordingly. Then, the limiting plug rod 12 is inserted into the side wall of the carrier plate 1, and the swing arm 3 is fixed. Then, the limiting rotating block 10 is rotated to make it leave the side wall of the protection box 2. The function of the limiting rotating block 10 is to prevent the protection box 2 from sliding freely on the upper surface of the carrier plate 1. Then, the screw rod 15 is rotated in the opposite direction. The screw rod 15 exits along the thread of the clamping block 14 and leaves the fixed rod 13. Then, the rotating disk 16 can be rotated. After the screw 15 is separated from the fixed rod 13, the first handle 5 and the second handle 7 lose their limits and can slide and unfold along the carrier plate 1. At this time, the driving column 6 is exposed, and the pipe joints to be polished can be placed on the grinding wheel 8 and the grinding rod 4 for edge grinding.
[0028] The inner and outer walls of the corners of the pipe joint are fitted with the grinding wheel 8 or the grinding column 4, and the excess parts on the pipe joint are ground and removed to facilitate subsequent connection with the pipeline. During the grinding process, the pipe joint can be held with both hands, which has higher grinding stability, reduces the burden on the hands, and improves the grinding quality. After the grinding of the pipe joint is completed, the pipe joint is inserted into the end of the pipeline, and a layer of sealant is evenly applied on the pipeline interface. The pipe joint connects the two pipes together to maintain sealing and prevent water leakage or seepage.
[0029] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
