AI Technical Summary
After a long time of use, the existing blade peripheral grinder feeding device is prone to rotation at a small angle, which causes the angle change in the blade feeding level position. The main reason is that there is a gap between the hexagonal rod and the hexagonal sleeve, which affects the Material accuracy.

DETAILED DESCRIPTION
[0023] 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.
[0024] Example: Reference Figure 1-3 The blade peripheral grinder feeding device shown comprises a feeding cylinder barrel 1, a cylinder rod 2 and a hexagonal rod 4 are respectively mounted at the upper and lower ends of the feeding cylinder barrel 1, and a blade feeding position 3 is fixed at the end of the cylinder rod 2;
[0025] The lower end of the feeding cylinder 1 is detachably connected to a sleeve 8 through a connecting piece. The sleeve 8 is sleeved on the outside of the hexagonal rod 4. The sleeve 8 is provided with a long sliding hole 81.
[0026] A positioning rod 7 is fixed to one side of the lower end of the hexagonal rod 4, and one end of the positioning rod 7 slides through the sliding hole 81;
[0027] A positioning structure is provided on the upper end of the positioning rod 7 and the top of the sliding hole 81. The positioning structure limits the position of the positioning rod 7 when it is pressed against the upper end of the sliding hole 81, so that the angle between the hexagonal rod 4 and the cylinder rod 2 is always consistent.
[0028] Based on the above structure, by adding a sleeve 8 on the outside of the hexagonal rod 4 and opening a sliding hole 81 on the sleeve 8, in conjunction with the use of the positioning rod 7, the hexagonal rod 4 drives the positioning rod 7 to slide along the sliding hole 81 when it shrinks, and when the positioning rod 7 coincides with the sliding hole 81, the positioning rod 7 is fixed at a certain angle through the positioning structure, so that the angle between the hexagonal rod 4 and the cylinder rod 2 is always consistent, thereby achieving high-precision repeated positioning of the blade loading position 3, avoiding the blade loading position 3 from deflecting at a certain angle due to the gap between the hexagonal rod 4 and the hexagonal sleeve in the loading cylinder 1, thereby ensuring that the loading accuracy of the blade peripheral grinder loading device remains consistent during long-term use, thereby improving the loading accuracy of the blade peripheral grinder loading device.
[0029] Furthermore, the positioning structure includes a right-angle positioning groove 811 and a right-angle portion 71 . The right-angle positioning groove 811 is arranged at the upper end of the sliding hole 81 . The right-angle portion 71 is formed at the upper end of the positioning rod 7 . The right-angle portion 71 is adapted to the right-angle positioning groove 811 .
[0030] When the positioning rod 7 moves to the upper end of the sliding hole 81, the right-angle portion 71 and the right-angle positioning groove 811 are tightly fitted, so that the angle of the positioning rod 7 is limited by the right-angle portion 71 and the right-angle positioning groove 811, and further the angle of the hexagonal rod 4 remains consistent after the movement, so that the angles of the cylinder rod 2 and the blade upper material position 3 are always consistent, thereby achieving the purpose of high-precision repeated positioning of the blade upper material position 3.
[0031] Furthermore, air cavities 83 are provided at both ends of the right-angle positioning groove 811, and an air bag 84 is fixed in the air cavity 83. When the right-angle portion 71 is not in contact with the right-angle positioning groove 811, one end of the air bag 84 extends to the outside of the air cavity 83 and forms an arc-shaped protrusion.
[0032] Through the arrangement of the air cavity 83 and the air bag 84, when the right-angle portion 71 approaches the right-angle positioning groove 811, the two sides of the right-angle portion 71 first contact with the air bag 84 and squeeze the air bag 84, so that the gas in the air bag 84 is compressed and shrinks, and finally the air bag 84 shrinks into the air cavity 83, thereby playing a certain damping and buffering role when the right-angle portion 71 is about to be in contact with the right-angle positioning groove 811, avoiding the right-angle portion 71 from colliding with the inner side of the right-angle positioning groove 811, thereby reducing or avoiding to a certain extent the wear between the right-angle portion 71 and the inner side of the right-angle positioning groove 811, and extending the service life of the positioning structure, thereby ensuring that the blade loading position 3 of the blade peripheral grinder loading device always maintains a high-precision repeated positioning effect during long-term use, thereby reducing the frequency of later maintenance.
[0033] Furthermore, a receiving groove 85 is opened at one end of the sliding hole 81 close to the right-angle positioning groove 811, and a round-head buffer rod 9 is slidably connected in the receiving groove 85. The round head end of the round-head buffer rod 9 extends out of the receiving groove 85, and the other end of the round-head buffer rod 9 is elastically connected to the inner wall of the receiving groove 85 through a compression spring 91.
[0034] Through the arrangement of the accommodating groove 85, the round-head buffer rod 9 and the compression spring 91, when the positioning rod 7 slides upward and approaches the right-angle positioning groove 811, the two sides of the right-angle portion 71 on the positioning rod 7 first contact with the round head end of the round-head buffer rod 9, and the round-head buffer rod 9 is forced to compress the compression spring 91, and finally the round-head buffer rod 9 is contracted in the accommodating groove 85. During this process, the round-head buffer rod 9 has a certain hindering effect on the movement of the positioning rod 7, so that the right-angle portion 71 is decelerated when it approaches the right-angle positioning groove 811. The simultaneous use of the air cavity 83 and the air bag 84 can better protect the right-angle portion 71 and the right-angle positioning groove 811, thereby achieving a better protection effect.
[0035] Further, the connecting piece includes a double-threaded nut 5 and an internally threaded nut sleeve 6. The double-threaded nut 5 is provided with threaded structures on both the inner and outer sides. The double-threaded nut 5 is threadedly connected to the lower end of the feeding cylinder barrel 1 through the inner threaded structure. The inner side of the internally threaded nut sleeve 6 is provided with a threaded structure. The internally threaded nut sleeve 6 is threadedly connected to the threaded structure on the outer side of the double-threaded nut 5 through the inner threaded structure.
[0036] The internally threaded nut sleeve 6 is sleeved on one end of the sleeve 8, and the sleeve 8 is detachably fixed to the end of the double-threaded nut 5 through the internally threaded nut sleeve 6. A gasket 82 is integrally formed at the upper end of the sleeve 8. The inner diameter of the gasket 82 is consistent with the inner diameter of the sleeve 8. The outer diameter of the gasket 82 is larger than the inner diameter of the double-threaded nut 5 and is the same as the inner diameter of the threaded structure of the internally threaded nut sleeve 6. The outer diameter of the gasket 82 is larger than the outer diameter of the sleeve 8, and the inner diameter of the lower end of the internally threaded nut sleeve 6 is the same as the outer diameter of the sleeve 8.
[0037] The sleeve 8 is detachably connected to the lower end of the feeding cylinder 1 through the double-threaded nut 5 and the internally threaded nut sleeve 6, which can facilitate the installation and disassembly of the sleeve 8, thereby facilitating the improvement of the existing blade peripheral grinder feeding device, which is beneficial to the promotion and use of the blade peripheral grinder feeding device, and also facilitates the replacement and maintenance of the damaged sleeve 8, making it more convenient to use.
[0038] The working principle of the utility model is as follows: in daily use, by adding a sleeve 8 on the outside of the hexagonal rod 4 and opening a sliding hole 81 on the sleeve 8, in conjunction with the use of the positioning rod 7, the hexagonal rod 4 drives the positioning rod 7 to slide along the sliding hole 81 when it is contracted. When the positioning rod 7 moves to the upper end of the sliding hole 81, the right-angle portion 71 and the right-angle positioning groove 811 are tightly matched, so that the angle of the positioning rod 7 is limited by the right-angle portion 71 and the right-angle positioning groove 811, and further the angle of the hexagonal rod 4 is always consistent after the movement, so that the angle of the cylinder rod 2 and the blade loading position 3 are always consistent, so as to achieve the purpose of high-precision repeated positioning of the blade loading position 3, and avoid the blade loading position 3 from deflecting a certain angle due to the gap between the hexagonal rod 4 and the hexagonal sleeve in the loading cylinder 1, thereby ensuring that the loading accuracy of the blade peripheral grinder feeding device is always consistent during long-term use, and improving the loading accuracy of the blade peripheral grinder feeding device.
[0039] 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.
