Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0019] Embodiment

[0020] Please refer to Figure 1 and Figure 2As shown in the figure, a pipe orifice grinding device for processing glass fiber reinforced plastic sand-filled pipes in this embodiment includes a workbench 1. Support legs are connected to the bottom of the workbench 1. A fixing frame 2 is connected to the top of the workbench 1 for supporting. A grinding assembly 3 is arranged between the two inner side walls of the fixing frame 2. A clamping and rotating assembly 4 is arranged below the grinding assembly 3. It is characterized in that: The grinding assembly 3 includes a guide rod 31, a moving block 32, a screw rod 33, a first motor 34, a first electric push rod 35, an inverted U-shaped plate 36, a grinding cylinder 37, and a grinding motor 38. The guide rod 31 is fixed to the upper parts of the two inner side walls of the fixing frame 2 and is slidably connected to the upper part of the moving block 32. The lower part of the moving block 32 is threadedly connected to the screw rod 33. Both ends of the screw rod 33 are rotatably connected to the two inner side walls of the fixing frame 2 through bearings respectively, and the right end of the screw rod 33 also passes through the right side wall of the fixing frame 2 and is connected to the output end of the first motor 34. The bottom of the moving block 32 is connected to the first electric push rod 35. The driving end of the first electric push rod 35 is fixedly connected to the center of the top of the inverted U-shaped plate 36. Both ends of the grinding cylinder 37 are rotatably connected to the two inner side walls of the inverted U-shaped plate 36 through bearings respectively. A grinding motor 38 is also arranged in the left direction of the inverted U-shaped plate 36. The output end of the grinding motor 38 passes through the left side wall of the inverted U-shaped plate 36 and is connected to the left end of the grinding cylinder 37.

[0021] It can be understood that by starting the forward and reverse rotation of the first motor 34 through the controller during implementation, the moving block 32 and the grinding cylinder 37 can be moved left and right. By starting the telescopic movement of the first electric push rod 35 through the controller, the grinding cylinder 37 can be moved up and down, that is, the grinding cylinder 37 can move freely up, down, left, and right. Then, by starting the grinding motor 38 through the controller to drive the grinding cylinder 37 to rotate, the pipe 10 can be ground.

[0022] Furthermore, the clamping and rotating assembly 4 includes a rotating cylinder 41, a fixed cylinder 42, an electric slider 43, a second electric push rod 44, and a clamping block 45. Both ends of the rotating cylinder 41 are rotatably connected to the two fixed cylinders 42 through bearings respectively. The two fixed cylinders 42 are symmetrically fixed on the top of the electric slider 43 with respect to the rotating cylinder 41. The electric slider 43 is slidably matched with the workbench 1. Three second electric push rods 44 are connected along the radial direction in the middle of the rotating cylinder 41, and the three second electric push rods 44 are evenly distributed circumferentially with the axis of the rotating cylinder 41 as the reference. The driving ends of the three second electric push rods 44 are all connected with clamping blocks 45.

[0023] Furthermore, the number of the clamping and rotating assemblies 4 is two. A gear ring 5 is fixedly sleeved in the middle of the outer side wall of the rotating cylinder 41 of the clamping and rotating assembly 4 on the right. A gear 6 is arranged at the bottom of the gear ring 5. A second motor 7 is arranged in the left direction of the gear 6. The second motor 7 is fixed on the top of the electric slider 43, and the gear 6 is meshed with the gear ring 5. The gear 6 is fixed on the output end of the second motor 7.

[0024] Further, the bottom of the electric slider 43 is in an inverted T shape, and an inverted T-shaped sliding groove 8 is formed on the workbench 1. The bottom of the electric slider 43 is slidably connected to the sliding groove 8.

[0025] Further, a limiting block 9 is further arranged between the two clamping and rotating assemblies 4, and the limiting block 9 is fixed at the middle of the top of the sliding groove 8.

[0026] It can be understood that in implementation, the limiting block 9 is arranged to prevent the two clamping and rotating assemblies 4 from colliding due to being too close, and clamping members for preventing the clamping and rotating assemblies 4 from detaching are further arranged at both ends of the sliding groove 8.

[0027] Further, the first motor 34, the grinding motor 38, the first electric push rod 35, the second electric push rod 44, the electric slider 43, and the second motor 7 are all electrically connected to an external controller.

[0028] It can be understood that in implementation, first, the electric slider 43 is started through the controller to make the distance between the two clamping and rotating assemblies 4 adapt to the length of the pipe 10. Then, the second electric push rod 44 is started through the controller to contract. Then, both ends of the pipe 10 are placed into the rotating cylinder 41. Next, the second electric push rod 44 is started through the controller to extend. The extension of the second electric push rod 44 will drive the clamping block 45 to clamp and fix the pipe 10, so that both ends of the pipe 10 with different diameters can be clamped. Then, the second motor 7 is started through the controller to drive the gear 6, the gear ring 5, and the rotating cylinder 41 to rotate. The rotation of the rotating cylinder 41 can drive the pipe 10 to rotate. Finally, in cooperation with the grinding assembly 3, burrs can be removed by grinding at various positions of the pipe 10. There is no need to manually adjust the grinding position of the pipe 10, which saves time and effort and is very convenient. Moreover, it can adapt to pipes 10 with different lengths and diameters, and has strong adaptability.

[0029] It can also be understood that since both ends of the pipe 10 are clamped and fixed, the clamped parts at both ends of the pipe 10 cannot be ground. At this time, the controller can be used to control one clamping and rotating assembly 4 to remain stationary, control the electric slider 43 to move the other clamping and rotating assembly 4, clamp the pipe 10 at another position, and then the original clamping position can be ground. Therefore, the pipe 10 can be comprehensively ground.
