[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The fastener grinding device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, the fastener grinding device of this utility model embodiment may include a base plate 10, a rotating mechanism 40, an intermittent rotating mechanism 60, and a plurality of fixing mechanisms 80. The top surface of the base plate 10 is provided with an electric slide rail 20, the electric slide rail 20 is connected to a first electric push rod 30, the rotating mechanism 40 is connected to the piston end of the first electric push rod 30, and the rotating mechanism 40 is connected to a plurality of grinding frames 50, and the plurality of grinding frames 50 are all different.

[0023] It should be noted that four fixing mechanisms 80 are used in this embodiment, and the grinding frame 50 is made of cemented carbide, which has high hardness and wear resistance, and matches the shape of the hexagonal nut. The multiple grinding frames 50 are all of different sizes, which can grind nuts of different specifications.

[0024] The top surface of the base plate 10 is provided with a protective shell 11. Intermittent rotation mechanisms 60 are respectively set inside the protective shell 11 and on the upper surface. One end of the intermittent rotation mechanism 60 passes through the protective shell 11 and is connected to the turntable 70. Multiple fixing mechanisms 80 are arranged circumferentially on the top surface of the turntable 70. The grinding frame 50 is located above the fixing mechanism 80.

[0025] Specifically, the workers first install each nut to be polished on the outside of each fixing mechanism 80. The fixing mechanism 80 clamps and fixes the inner wall of the nut. During the fixing process, the placement direction of adjacent nuts differs by 90 degrees. The nuts located below the polishing frame 50 are placed in the same direction as the polishing frame 50. This way, when other nuts are rotated to the bottom of the polishing frame 50, their placement direction can be consistent with the polishing frame 50.

[0026] After fixing, start the electric slide rail 20 to adjust the position of the grinding frame 50 so that the grinding frame 50 is moved directly above the nut. Then start the first electric push rod 30 to drive the grinding frame 50 to move downward so that the six inner walls of the grinding frame 50 fit into the six outer walls of the nut. Then control the first electric push rod 30 to drive the grinding frame 50 to move back and forth. The grinding frame 50 will move up and down on the outer wall surface of the nut, and use its six inner walls to grind the six outer walls of the nut.

[0027] Then, the intermittent rotation mechanism 60 is activated, which drives the turntable 70 to rotate intermittently. This causes each nut to rotate to the bottom of the grinding frame 50, and multiple nuts are continuously ground. When it is necessary to grind nuts of different sizes, the rotation mechanism 40 is activated, which drives multiple grinding frames 50 to rotate and adjust the position of the multiple grinding frames 50 so that the grinding frame 50 located above the turntable 70 is adapted to the size of the nut.

[0028] The fastener grinding device of this utility model can grind the outer wall of the nut comprehensively without grinding each side, thereby effectively shortening the grinding time and improving the grinding efficiency.

[0029] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the rotating mechanism 40 may include a first driver 41, a rotating plate 42 and a plurality of support rods 43. The first driver 41 is connected to the piston end of the first electric push rod 30, the rotating plate 42 is connected to the output end of the first driver 41, the plurality of support rods 43 are respectively connected to the rotating plate 42, and the plurality of grinding frames 50 are respectively connected to the corresponding support rods 43.

[0030] It should be noted that the first driver 41 described in this embodiment can be a servo motor. The first driver 41 can drive the rotating plate 42 to rotate at a certain angle, thereby driving multiple support rods 43 to move, thereby adjusting the position of multiple grinding frames 50, so that the grinding frame 50 above the fixing mechanism 80 can be adapted to the size of the nut.

[0031] In one embodiment of this utility model, such as Figure 1 and Figure 3As shown, the intermittent rotation mechanism 60 may include a disc 61, an arc plate 62, an eccentric rod 63, a second driver 64, a rotating frame 65, and a rotating shaft 67. The disc 61 is disposed inside the protective shell 11. The arc plate 62 and the eccentric rod 63 are respectively connected to the disc 61. The second driver 64 is disposed on the upper surface of the protective shell 11, and the output end of the second driver 64 passes through the protective shell 11 and is connected to the disc 61. The rotating frame 65 is in contact with the arc plate 62. The rotating frame 65 is provided with a plurality of grooves 66 that cooperate with the eccentric rod 63. The rotating frame 65 is connected to the rotating shaft 67, and one end of the rotating shaft 67 passes through the protective shell 11 and is connected to the turntable 70.

[0032] It should be noted that the second driver 64 described in this embodiment can be a motor, and four grooves 66 are selected. The second driver 64 can drive the disc 61, the arc plate 62 and the eccentric rod 63 to rotate. When the eccentric rod 63 rotates into the groove 66 of the rotating frame 65, it will push the rotating frame 65 to rotate. Whenever the eccentric rod 63 completes a round of entering and exiting the groove 66, the rotating frame 65 and the rotating shaft 67 experience a pause followed by rapid rotation, thereby causing different nuts to stay below the grinding frame 50, so as to continuously grind multiple nuts.

[0033] In one embodiment of this utility model, such as Figure 4 As shown, the fixing mechanism 80 may include a T-shaped block 81, a second electric push rod 82, a first arc-shaped clamping plate 83, and a second arc-shaped clamping plate 84. The T-shaped block 81 is disposed on the top surface of the turntable 70, the second electric push rod 82 is disposed on one side of the T-shaped block 81, the first arc-shaped clamping plate 83 is connected to the piston end of the second electric push rod 82, and the second arc-shaped clamping plate 84 is connected to the T-shaped block 81.

[0034] It should be noted that by controlling the extension and retraction of the piston end of the second electric push rod 82, the position of the first arc-shaped clamping plate 83 can be moved, thereby adjusting the distance between the first arc-shaped clamping plate 83 and the second arc-shaped clamping plate 84, so that the first arc-shaped clamping plate 83 and the second arc-shaped clamping plate 84 respectively fit against the inner wall of the nut and clamp and fix it.

[0035] In one embodiment of this utility model, such as Figure 1 As shown, an inspection door 12 is hinged to one side of the protective shell 11.

[0036] It is understandable that the inspection door 12 is provided to facilitate staff to open the protective shell 11 and perform maintenance on the internal structure.

[0037] In summary, the fastener grinding device of this utility model embodiment can grind the outer wall of the nut comprehensively without grinding each side individually, thereby effectively shortening the grinding time and improving grinding efficiency.
