[0015] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0016] like Figure 1-3As shown, a hexagonal flange nut edge grinding device includes a mounting plate 1, a limiting groove is provided on the mounting plate 1, a bottom plate 3 is provided at the bottom of the limiting groove, a wedge 4 is provided at the lower end of the bottom plate 3, a placement cavity 5 is provided at one end of the mounting plate 1, a cylinder 6 is provided inside the placement cavity 5, a bottom shell 7 is provided at the lower end of the mounting plate 1, a push rod 8 is slidably connected inside the bottom shell 7, one end of the push rod 8 abuts against the lower surface of the wedge 4, an output end of the cylinder 6 is fixedly connected to the other end of the push rod 8, a through groove for moving the push rod 8 is provided on the mounting plate 1, a clamping plate 9 is provided on the output end of the cylinder 6, and a placement cavity 5 is provided with a clamping plate 9. A receiving groove is provided, and the card plate 9 is located inside the receiving groove. Limiting plates 10 are respectively provided on both sides of the upper surface of the mounting plate 1, and side plates 11 are respectively provided on both sides of the bottom plate 3. A fixing ring 12 is provided on the upper end of the side plate 11. A turntable 13 is rotatably connected inside the fixing ring 12. A box body 14 is provided on the turntable 13. A motor 15 is slidably connected inside the box body 14. An elastic block 16 is also provided inside the box body 14. A waist hole 17 for moving the output end of the motor 15 is provided on the turntable 13. A grinding wheel 18 is provided at the output end of the motor 15. A handle 19 is provided on the upper end of the box body 14.

[0017] In the initial state, the elastic block 16 is used to pull the motor 15 toward the center of the turntable 13. At this time, the output end of the motor 15 abuts against the end of the waist hole 17 close to the center of the turntable 13. When the flange nut 2 enters onto the bottom plate 3, the grinding wheel 18 is squeezed by the flange nut 2, so that the motor 15 moves away from the center of the turntable 13, and the elastic block 16 is in a stretched state.

[0018] When grinding the outer edge surface of the flange end of the flange nut 2, first control the rotation of the turntable 13 by the handle 19 to move the grinding wheel 18 to the side of the mounting plate 1, then align the two side surfaces of the flange nut 2 with the limit plates 10 on both sides respectively, and then start the cylinder 6, and the cylinder 6 pushes the flange nut 2 to move through the clamping plate 9. The clamping plate 9 is V-shaped, which is convenient for improving the stability of pushing the flange nut 2 to move. When the clamping plate 9 pushes the flange nut 2 to move, the cylinder 6 simultaneously pushes the push rod 8 to move. One end of the push rod 8 cooperates with the wedge block 4 and pushes the wedge block 4 to move upward. When the wedge block 4 moves upward, it drives the bottom plate 3 to move upward. When the bottom plate 3 moves upward, it pushes the flange nut 2 in the limit groove to move upward. When the upper surface of the bottom plate 3 and the upper surface of the mounting plate 1 are in the same plane, the flange nut 2 pushed by the clamping plate 9 is now ready to connect with the flange nut 2 on the bottom plate 3. When the output end of the cylinder 6 continues to extend, the height of the base plate 3 will not continue to rise, and the clamping plate 9 will push the flange nut 2 in contact with it to the top of the base plate 3, and the flange nut 2 originally located above the base plate 3 will be pushed out by the newly pushed flange nut 2. When the unground flange nut 2 enters the base plate 3, the previous flange nut 2 falls off the mounting plate 1, and then the output end of the cylinder 6 stops extending. When the unground flange nut 2 enters the base plate 3 from the outside of the base plate 3, the elastic potential energy of the elastic block 16 enables the grinding wheel 18 to tightly abut against the outer edge surface of the flange nut 2, and then the output end of the cylinder 6 is controlled to retract. When the output end of the cylinder 6 retracts, the height of the wedge block 4 is reduced through the cooperation of the push rod 8 and the wedge block 4, and the height of the base plate 3 is reduced, thereby facilitating the unground flange nut 2 to enter the limiting groove.

[0019] When grinding the flange nut 2, the motor 15 is started, the motor 15 drives the grinding wheel 18 to rotate, and then the turntable 13 is controlled to rotate in the fixing ring 12 through the handle 19, so that the outer edge surface of the flange end of the flange nut 2 can be ground.

[0020] Furthermore, a limit rod 20 is provided on the lower surface of the turntable 13. When the lower end of the limit rod 20 abuts against the upper surface of the flange nut 2 in the placement groove, the grinding wheel 18 can grind the upper and lower sides of the outer edge surface of the flange end of the flange nut 2 at the same time.

[0021] Furthermore, an inclined surface is provided between the upper surface of the placement cavity 5 and the upper surface of the mounting plate 1, and the flange nut 2 can be moved from the upper surface of the placement cavity 5 to the upper surface of the mounting plate 1 through the inclined surface. Multiple flange nuts 2 can be pre-placed on the placement cavity 5. When the unground flange nut 2 is placed on the base plate 3, the flange nut 2 on the placement cavity 5 is first pushed onto the mounting plate 1 through the inclined surface on the placement cavity 5, and then the flange nuts 2 are pushed and moved in sequence through the cooperation of the cylinder 6 and the block.

[0022] Furthermore, a marking point 21 for indicating the grinding wheel 18 is provided on the handle 19, so that the position of the grinding wheel 18 can be determined through the marking point 21. Before placing the unground flange nut 2 on the base plate 3, the grinding wheel 18 needs to be moved to the side position of the mounting plate 1 to prevent the grinding wheel 18 from affecting the movement of the flange nut 2 on the mounting plate 1.

[0023] Furthermore, the limiting plate 10 is made of nylon plastic, which is convenient for reducing the friction between the limiting plate 10 and the flange nut 2 .

[0024] When the device is grinding the edge of the flange nut 2, the staff only needs to place the flange nut 2 on the mounting plate 1. The subsequent accurate placement of the flange nut 2 and the transfer of the previously ground flange nut 2 do not require the staff to manually move it away, and the placement of the unground flange nut 2 and the transfer of the ground flange nut 2 can be carried out at the same time, thereby reducing work intensity and improving processing efficiency.

[0025] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
