[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0021] Please see Figure 1-5 The present invention provides the following technical solution: a centrifugal grinding rod with strong applicability, including a mounting head 1, a mounting groove 2 at one end of the mounting head 1, a mounting rod 6 at the other end of the mounting head 1, an upper grinding rod 3 rotatably connected to one side of the upper end of the mounting rod 6 via a rotating shaft, a lower grinding rod 5 rotatably connected to one side of the lower end of the mounting rod 6 via a rotating shaft, the mounting rod 6 and the mounting head 1 are fixedly connected by a grinding rod disassembly and assembly mechanism 7, and a centrifugal grinding structure 4 is provided at the other end of the upper grinding rod 3 and the lower grinding rod 5.
[0022] Specifically, the grinding rod assembly / disassembly mechanism 7 includes a fixing hole 71, a fixing block 72, a fixing component 73, and a fixing groove 75. A fixing block 72 is provided at one end of the mounting rod 6. A fixing hole 71 is provided on the side of the fixing block 72. A fixing groove 75 corresponding to the fixing block 72 is provided on the side of the mounting head 1. A fixing component 73 is provided inside the mounting head 1.
[0023] By adopting the above technical solution, the fixing block 72 at one end of the mounting rod 6 is inserted into the fixing groove 75 on the side of the mounting head 1, and then, with the fixing component 73 and the fixing hole 71, the mounting rod 6 and the mounting head 1 can be installed and fixed.
[0024] Specifically, the grinding rod disassembly and assembly mechanism 7 also includes a pin 74 and a socket 76. The mounting head 1 is internally fitted with a pin 74, and the fixing block 72 has a corresponding socket 76 inside.
[0025] By adopting the above technical solution, the fixing reliability of the mounting head 1 and the mounting rod 6 can be improved by using the pin 74 in conjunction with the insertion hole 76.
[0026] Specifically, the fixing component 73 includes a fixing rod 731, a limiting plate 732, a spring 733, a pull rod 734, and a handle 735. The mounting head 1 has a limiting plate 732 inside. One end of the limiting plate 732 is provided with the fixing rod 731, and the other end of the limiting plate 732 is provided with the pull rod 734. The other end of the pull rod 734 is provided with a handle 735, and the surface of the pull rod 734 is fitted with a spring 733.
[0027] By adopting the above technical solution, pulling the handle 735 will pull the lever 734, which in turn will pull the limiting plate 732 and the fixing rod 731, and cause the spring 733 to compress. At this time, the fixing block 72 at one end of the mounting rod 6 will be inserted into the fixing groove 75 on the side of the mounting head 1. When the handle 735 is released, the spring 733 will rebound, thereby causing the fixing rod 731 to be inserted into the fixing hole 71, thus realizing the installation and fixing of the mounting head 1 and the mounting rod 6.
[0028] In this embodiment, when in use, the handle 735 is pulled, which in turn pulls the lever 734. The lever 734 pulls the limiting plate 732 and the fixing rod 731, and compresses the spring 733. Then, the fixing block 72 at one end of the mounting rod 6 is inserted into the fixing groove 75 on the side of the mounting head 1. The handle 735 is released, and the spring 733 rebounds, thereby driving the fixing rod 731 to be inserted into the fixing hole 71. This achieves the installation and fixing of the mounting head 1 and the mounting rod 6. The fixing reliability of the mounting head 1 and the mounting rod 6 can be improved by using the pin 74 in conjunction with the insertion hole 76. Example 2
[0029] The difference between this embodiment and Embodiment 1 is that the centrifugal grinding structure 4 includes a mounting hole 42, a stop 43, a groove 44, a centrifugal grinding head 45, and a slider 46. Mounting holes 42 are provided on the side of one end of the upper grinding rod 3 and the lower grinding rod 5. A slider 46 is provided on the inner wall of the mounting hole 42. A stop 43 is provided inside the lower grinding rod 5 corresponding to the position of the mounting hole 42. The centrifugal grinding head 45 is slidably connected inside the mounting hole 42. A groove 44 corresponding to the slider 46 is provided on the side of the centrifugal grinding head 45.
[0030] By adopting the above technical solution, when installing the centrifugal grinding head 45, the upper grinding rod 3 and the lower grinding rod 5 are offset by the rotating shaft. Then, the centrifugal grinding head 45 is placed into the mounting hole 42. The stop block 43 prevents the centrifugal grinding head 45 from sliding out of the mounting hole 42 during use. Then, the mounting head 1 is fixed to the side of the rotating head, and the grinding rod is placed into the inner hole of the workpiece. When the rotating head drives the grinding rod to rotate, the centrifugal grinding head 45 will slide outward due to the centrifugal force, thereby grinding the inner hole of the workpiece. When the centrifugal grinding head 45 slides outward, it will drive the slider 46 to slide inside the groove 44, thereby improving the stability of the centrifugal grinding head 45 sliding outward.
[0031] Specifically, the centrifugal grinding structure 4 also includes an arc groove 41 and an arc block 47. An arc block 47 is provided on one side of the lower end of the upper grinding rod 3, and an arc groove 41 corresponding to the arc block 47 is provided on the upper end of the lower grinding rod 5.
[0032] By adopting the above technical solution, when the upper grinding rod 3 rotates through the shaft, it will drive the arc block 47 to slide inside the arc groove 41 at the upper end of the lower grinding rod 5, thereby avoiding the problem of the upper grinding rod 3 and the lower grinding rod 5 being misaligned too much.
[0033] In this embodiment, when installing the centrifugal grinding head 45, the upper grinding rod 3 and the lower grinding rod 5 are offset by the rotating shaft. Then, the centrifugal grinding head 45 is placed inside the mounting hole 42. The stop block 43 prevents the centrifugal grinding head 45 from sliding out of the mounting hole 42 during use. The mounting head 1 is then fixed to the side of the rotating head, and the grinding rod is placed into the inner hole of the workpiece. When the rotating head drives the grinding rod to rotate, the centrifugal grinding head 45 will slide outward due to centrifugal force, thereby grinding the inner hole of the workpiece. When the centrifugal grinding head 45 slides outward, it will drive the slider 46 to slide inside the groove 44, thereby improving the stability of the centrifugal grinding head 45 sliding outward. When the upper grinding rod 3 rotates by the rotating shaft, it will drive the arc block 47 to slide inside the arc groove 41 at the upper end of the lower grinding rod 5, thereby avoiding the problem of excessive misalignment between the upper grinding rod 3 and the lower grinding rod 5.
[0034] The working principle and usage process of this utility model are as follows: When using this utility model, pulling the handle 735 pulls the pull rod 734, which in turn pulls the limiting plate 732 and the fixing rod 731, and compresses the spring 733. At this time, the fixing block 72 at one end of the mounting rod 6 is inserted into the fixing groove 75 on the side of the mounting head 1. Releasing the handle 735 causes the spring 733 to rebound, thereby driving the fixing rod 731 to be inserted into the fixing hole 71, thus realizing the installation and fixing of the mounting head 1 and the mounting rod 6. The fixing reliability of the mounting head 1 and the mounting rod 6 can be improved by using the pin 74 in conjunction with the insertion hole 76. When installing the centrifugal grinding head 45, the upper grinding rod 3 and the lower grinding rod 5 are offset by the rotating shaft. Then, the centrifugal grinding head 45 is placed into the mounting hole. Inside the mounting hole 42, the stop block 43 prevents the centrifugal grinding head 45 from sliding out of the mounting hole 42 during use. Then, the mounting head 1 is fixed to the side of the rotating head, and the grinding rod is placed into the inner hole of the workpiece. When the rotating head drives the grinding rod to rotate, the centrifugal grinding head 45 will slide outward due to centrifugal force, thus grinding the inner hole of the workpiece. When the centrifugal grinding head 45 slides outward, it will drive the slider 46 to slide inside the groove 44, thereby improving the stability of the centrifugal grinding head 45 sliding outward. When the upper grinding rod 3 rotates through the shaft, it will drive the arc block 47 to slide inside the arc groove 41 at the upper end of the lower grinding rod 5, thereby avoiding the problem of the upper grinding rod 3 and the lower grinding rod 5 being misaligned too much.
