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] See also Figure 1-6 The utility model provides a technical solution: a special-shaped plate chamfering wheel, comprising a chamfering wheel body 1 and a flange 12, a shaft sleeve 2 passing through the middle of the chamfering wheel body 1, a lower shell 6 is provided below the chamfering wheel body 1, and plug rods 9 are distributed at annular intervals on the side of the chamfering wheel body 1 close to the lower shell 6, a slot 10 is provided on the side of the lower shell 6 close to the plug rod 9, a screw sleeve 13 is threadedly sleeved on the outer side of the shaft sleeve 2, a knife block 11 is provided above the chamfering wheel body 1, mounting mechanisms 8 are provided at both ends of the chamfering wheel body 1 close to the lower shell 6, a protective mechanism 5 is provided on the inner side of the lower shell 6, the flange 12 is installed on one side of the lower shell 6 by bolts 3, a threaded hole 4 is opened on the side of the lower shell 6 close to the bolt 3, and a docking mechanism 7 is provided on the side of the lower shell 6 close to the flange 12.

[0025] according to Figure 1 and Figure 4-5 As shown, the protective mechanism 5 includes a buffer spring 51, a fixing ring 52 and a ball 53. The buffer spring 51 is provided in the built-in groove of the lower shell 6, and a ball 53 is provided on one side of the buffer spring 51. A fixing ring 52 is fixed to the outer side of the sleeve 2. There are four protective mechanisms 5.

[0026] In specific implementation, when the chamfering wheel rotates at high speed, wear will occur on the inner wall where the chamfering wheel and the sleeve 2 are sleeved due to the action of high-speed rotation and pressure. The fixing ring 52 on the outside of the sleeve 2 can rub and squeeze the ball 53, so that the ball 53 squeezes the buffer spring 51, making the ball 53 have buffering properties, which can reduce the wear and pressure between the sleeve 2 and the lower shell 6 and the chamfering wheel body 1, thereby increasing the service life of the chamfering wheel.

[0027] according to Figure 1-2 and Figure 4 As shown, the docking mechanism 7 includes a docking hole 71, a docking rod 72 and a fastening ring 73. The docking rods 72 are fixed to one side of the lower shell 6 with intervals. The flange 12 is provided with a docking hole 71 on the side close to the docking rod 72. The outer side of the docking rod 72 is sleeved with a fastening ring 73, and the fastening ring 73 and the docking rod 72 are threadedly sleeved.

[0028] During specific implementation, since the chamfering wheel will become loose after being used for a long time, the docking rod 72 can be engaged with the docking hole 71 when the lower shell 6 is connected to the flange 12, and then the fastening ring 73 is rotated to limit the docking rod 72. This can make the flange 12 and the lower shell 6 tightly connected, thereby improving the stability of the chamfering wheel.

[0029] according to Figure 1 and Figure 3-6 As shown, the mounting mechanism 8 includes a mounting hole 81, a limiting rod 82, a reset spring 83 and a connecting block 84. The two ends of the chamfering wheel body 1 close to the lower shell 6 are connected with connecting blocks 84. The interior of the connecting block 84 passes through the limiting rod 82. The outer side of the limiting rod 82 is sleeved with a reset spring 83. The lower shell 6 is provided with mounting holes 81 on both sides close to the limiting rod 82. There is a snap-fit ​​structure between the limiting rod 82 and the mounting hole 81, and the connecting block 84 is arc-shaped.

[0030] During specific implementation, when the chamfering wheel is worn and needs to be replaced, first rotate the screw sleeve 13 to remove the screw sleeve 13 from the shaft sleeve 2, and then pull the limit rod 82 to one side, so that the limit rod 82 drives the return spring 83 to contract, driving one end of the limit rod 82 to disengage from the mounting hole 81, and then pull the chamfering wheel body 1 upward to disengage the insertion rod 9 from the slot 10, so that the chamfering wheel body 1 can be quickly disassembled and replaced without removing the flange 12, thereby improving the convenience of the chamfering wheel.

[0031] Working principle: When using this type of special-shaped plate chamfering wheel, first, install the lower shell 6 and the flange 12 through the bolts 3 and the docking mechanism 7, and then connect the chamfering wheel body 1 and the lower shell 6 through the installation mechanism 8 and the insertion rod 9. During the high-speed rotation of the chamfering wheel to chamfer and grind the edge of the special-shaped plate, the protective mechanism 5 can reduce the wear between the sleeve 2 and the chamfering wheel body 1, thereby improving the convenience of the chamfering wheel and extending its service life. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or 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 invention shall be included in the protection scope of the present invention.
