[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] See also Figures 1-4 , the utility model provides a technical solution: a deburring device for a keyboard sealing ring, comprising a frame 1, an outer grinding wheel 2, a supporting mechanism and an inner grinding wheel 3;
[0024] The bottom end of the outer grinding wheel 2 passes through the frame 1 and is rotatably connected to the frame 1. The drive motor 4 is fixedly installed on the inner side of the frame 1, and the output shaft of the drive motor 4 is connected to the bottom end of the outer grinding wheel 2; the supporting mechanism includes a fixed wheel 5 and an auxiliary wheel 6 arranged above the frame 1. The auxiliary wheel 6 can move along the length direction of the frame 1, and the fixed wheel 5 and the auxiliary wheel 6 support the keyboard sealing ring; the inner grinding wheel 3 and the fixed wheel 5 are arranged side by side, and the bottom end of the inner grinding wheel 3 passes through the frame 1 and is rotatably connected to the frame 1.
[0025] like Figure 2 As shown, the bottom end of the outer grinding wheel 2 is fixedly sleeved with a driving gear 7 located on the inner side of the frame 1, and the bottom end of the fixed wheel 5 is fixedly sleeved with a driven gear 8 that meshes with the driving gear 7; when the driving motor 4 rotates the outer grinding wheel 2, it can drive the driving gear 7 to rotate, and the driving gear 7 cooperates with the driven gear 8 to provide power for the rotation of the fixed wheel 5.
[0026] like Figure 3 As shown, the bottom end of the fixed wheel 5 is fixedly sleeved with a transfer gear 9 located above the driven gear 8, and the bottom end of the inner grinding wheel 3 is fixedly sleeved with a terminal gear 10 engaged with the transfer gear 9; when the fixed wheel 5 rotates, it can drive the transfer gear 9 to rotate, and the transfer gear 9 provides power for the rotation of the inner grinding wheel 3 by cooperating with the terminal gear 10.
[0027] like Figure 3As shown, a through slot 11 is provided on the top of the frame 1, and there is a certain gap between the left side of the inner wall of the through slot 11 and the terminal gear 10; the through slot 11 provides a channel for the movement of the auxiliary wheel 6, and the moving block 14 will not contact the terminal gear 10.
[0028] like Figure 2 As shown, the support mechanism also includes a screw 12 rotatably connected to the through slot 11, the right end of the screw 12 passes through the frame 1 and is fixedly connected to a hand crank 13, a moving block 14 is threadedly connected to the outer wall of the screw 12, and the auxiliary wheel 6 is rotatably set on the top of the moving block 14; the hand crank 13 can control the rotation of the screw 12, and the screw 12 drives the moving block 14 to drive the auxiliary wheel 6 to move to tighten the keyboard sealing ring through thread transmission.
[0029] like Figure 4 As shown, the side cross-sections of the through groove 11 and the movable block 14 are both "I"-shaped, and the movable block 14 is located on the inner side of the through groove 11 and slides with the through groove 11; when the screw 12 drives the movable block 14 to move, the movable block 14 tends to rotate circumferentially, and at this time it is limited by the through groove 11, so that the movable block 14 can only move in a straight line along the through groove 11.
[0030] How to use and working principle of this device:
[0031] First, put the keyboard sealing ring between the fixed wheel 5 and the auxiliary wheel 6, and use the hand crank 13 to rotate the screw 12, driving the moving block 14 to slide along the through slot 11 and drive the auxiliary wheel 6 to move until the auxiliary wheel 6 moves to tighten the keyboard sealing ring and stops;
[0032] Then, the driving motor 4 is turned on, and the driving motor 4 directly drives the outer grinding wheel 2 to rotate. The rotation of the outer grinding wheel 2 will drive the driving gear 7 to cooperate with the driven gear 8 to rotate the fixed wheel 5. When the fixed wheel 5 rotates, it will drive the transfer gear 9 to cooperate with the terminal gear 10 to rotate the inner grinding wheel 3. Since the fixed wheel 5 and the auxiliary wheel 6 tighten the keyboard sealing ring and the fixed wheel 5 rotates, the keyboard sealing ring is transmitted between the fixed wheel 5 and the auxiliary wheel 6 through friction. At this time, the rotating outer grinding wheel 2 and the inner grinding wheel 3 grind the outer and inner sides of the keyboard sealing ring to remove burrs.
[0033] In summary, in the present invention, keyboard sealing rings of different sizes can be tensioned. After tensioning, the outer grinding wheel 2, the inner grinding wheel 3 and the fixed wheel 5 are rotated by driving the motor 4. While driving the keyboard sealing ring to move, the outer and inner sides are polished to remove burrs, which effectively solves the problem that the keyboard sealing ring is slender and not conducive to polishing. It also replaces manual operation, improves efficiency, reduces labor intensity, and reduces scrap rate.
[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
