Existing grinding methods typically involve placing the pipe on a support frame, fixing it in place, and then grinding it with grinding equipment. After grinding, the fixing must be removed before the pipe can be taken out. The whole process is cumbersome and time-consuming. Therefore, it is of great significance to study a new end grinding device for HDPE water supply pipe processing production lines to solve the above problems. Utility Model Content

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The end grinding device of this HDPE water supply pipe processing production line is equipped with a rotating component, a sector wheel, ball bearings, a piston assembly, and a clamping assembly. By placing the water pipe between two clamping plates, the rotating component drives the rotating plate to rotate, causing the water pipe to move. The ball bearings are squeezed by the arc surface of the sector wheel, which in turn drives the piston assembly to move. The piston assembly forces the liquid inside the shell into the cylinder, and the two clamping assemblies automatically clamp and fix the water pipe, and make the end of the water pipe fit against the grinding assembly. At this time, the end of the water pipe can be ground by the grinding assembly. Therefore, this method does not require separate fixing of the water pipe, thus improving the processing efficiency.

[0015] 2. The end grinding device of this HDPE water supply pipe processing production line, by setting up a piston assembly and a fan-shaped wheel, after the water pipe is ground, the rotating plate continues to drive the water pipe to rotate, so that the ball moves away from the arc surface of the fan-shaped wheel. At this time, the elastic force of the spring can drive the first piston to reset, so that the liquid is reintroduced into the shell. At this time, the clamping assembly can remove the water pipe, thus facilitating the discharge of the water pipe.

[0016] 3. The end grinding device of this HDPE water supply pipe processing production line is equipped with a rotating component and a rotating plate. The rotating shaft is driven to rotate by a dual-axis motor. The rotating shaft drives the rotating plate to rotate, so that the rotating plate can change the direction of the water pipe through the clamping component, so that the end of the water pipe is in contact with the grinding wheel, which facilitates subsequent grinding operations. At the same time, the positions of multiple clamping components can be switched, so that the water pipe can continue to be placed during the grinding process, which is conducive to continuous processing operations.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figure 1-4As shown, this utility model provides a technical solution: an end grinding device for an HDPE water supply pipe processing production line, including a base 1. A grinding component 3 and two fixing rods 5 are fixedly connected to the top of the base 1. The grinding component 3 includes a fixing column 31, and a first motor 33 is fixedly connected to the top of the fixing column 31. A grinding wheel 32 is fixedly connected to the output shaft of the first motor 33. The grinding wheel 32 is driven to rotate by the first motor 33, so that the grinding wheel 32 can perform grinding operations on the end of the water pipe. A fan-shaped wheel 8 is fixedly connected to the upper end of the fixing rods 5. A rotating component 2 is fixedly connected to the top of the base 1. The rotating component 2 includes a dual-axis motor 21. A fixing frame 24 is fixedly connected to the lower part of the dual-axis motor 21. The fixing frame 24 can fix the dual-axis motor 21, thereby ensuring... To ensure the stability of the dual-axis motor 21, a mounting bracket 24 is fixedly connected between two mounting plates 23. Both output shafts of the dual-axis motor 21 are fixedly connected to rotating shafts 22. One end of each rotating shaft 22 is fixedly connected to a rotating plate 4. The dual-axis motor 21 drives the rotating shaft 22 to rotate, which in turn drives the rotating plate 4 to rotate. This allows the rotating plate 4 to change the direction of the water pipe via the clamping assembly 6, ensuring the end of the water pipe fits against the grinding wheel 32 for subsequent grinding operations. Furthermore, the positions of the multiple clamping assemblies 6 can be switched, allowing the water pipe to continue being placed during grinding, thus facilitating continuous processing. The rotating shaft 22 is rotatably connected to a bearing 25, which ensures the smooth operation of the rotating shaft 22 and reduces rotational resistance. The bearing 25 is fixedly connected to the mounting plate 23. The fixed plate 23 is fixedly connected to the base 1. Rotating plates 4 are fixedly connected to both ends of the rotating assembly 2. Four housings 7 are fixedly connected to one side of the rotating plate 4. Two piston assemblies 9 are provided in each housing 7. Each piston assembly 9 includes a first piston 92. The housing 7 is divided into two inner cavities, each storing liquid separately to ensure uniform liquid flow into the corresponding cylinder 13. The two first pistons 92 are respectively located in the two inner cavities. The first pistons 92 are fixedly connected to the movable column 10. A spring 91 is fixedly connected between the first piston 92 and the side wall of the housing 7. After the water pipe is polished, the rotating plate 4 continues to rotate the water pipe, causing the ball bearing 11 to move away from the arc surface of the fan-shaped wheel 8. At this time, the elastic force of the spring 91 can drive the first piston 92 to reset, allowing the liquid to be reintroduced into the housing 7. The water pipe can be removed by clamping component 6, facilitating water discharge. Movable columns 10 are fixedly connected to both piston assemblies 9. These columns 10 extend from the housing 7 and are fixedly connected to ball bearings 11. The ball bearings 11 reduce friction with the sector wheel 8, improving smoothness. Furthermore, the arc surface of the sector wheel 8 can compress the ball bearings 11, thus pushing the first piston 92 through the movable columns 10. The ball bearings 11 cooperate with the sector wheel 8. Both sides of the housing 7 are connected to infusion pipes 12, which facilitate liquid transport. One end of each infusion pipe 12 is connected to a cylinder 13, which is fixedly connected to the rotating plate 4. A clamping component 6 is installed in the cylinder 13, including a second piston 61 located within the cylinder 13.A connecting rod 62 is fixedly connected to one side of the second piston 61. One end of the connecting rod 62 extends out of the cylinder 13 and is fixedly connected to the clamping plate 63. The clamping plate 63 is provided with a rubber layer, which, through deformation, improves the clamping reliability of the water pipe and prevents damage to the surface of the water pipe.

[0024] The working principle of this utility model is as follows: By placing the water pipe between two clamping plates 63, and then controlling the dual-axis motor 21 to drive the rotating shaft 22 to rotate the rotating plate 4, the rotating plate 4 drives the clamping plate 63 to move, and the ball bearing 11 moves along the arc surface of the fan-shaped wheel 8, so that the arc surface of the fan-shaped wheel 8 squeezes the roller, drives the movable column 10 and the first piston 92 to move, so that the first piston 92 squeezes the spring 91 to move, so that the piston forces the liquid inside the shell 7 into the cylinder 13, so that the second piston 61 drives the clamping plate 63 to move through the connecting rod 62, so that the clamping plate 63 clamps the water pipe, and the water pipe is in contact with the grinding wheel 32. At this time, the first motor 33 can be controlled to drive the grinding wheel 32 to rotate and grind the end of the water pipe. After grinding, the rotating plate 4 continues to drive the water pipe to rotate. When the ball bearing 11 moves away from the arc surface of the fan-shaped wheel 8, the spring 91 drives the first piston 92 to reset, so that the liquid is introduced into the shell 7, and the second piston 61 drives the clamping plate 63 away from the water pipe through the connecting rod 62, so that the water pipe can fall smoothly for discharge.
