When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be an intermediate component.

[0070] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0071] like Figures 1 to 11As shown, the present application provides an automatic grinding machine 100 for grinding a workpiece 101, wherein the workpiece 101 has a through hole 102. The automatic grinding machine 100 includes a body 10, a tooling 20 and a friction wheel 30. The tooling 20 is installed on the body 10, and the workpiece 101 can be sleeved on the tooling 20; the friction wheel 30 is movably installed on the body 10, and the friction wheel 30 can contact the workpiece 101 and can drive the workpiece 101 to rotate. The friction wheel 30 and / or the tooling 20 can grind the workpiece 101. The workpiece 101 is placed on the tooling 20, the friction wheel 30 contacts the workpiece 101, and the workpiece 101 is pressed against the tooling 20. The friction wheel 30 rotates, and the friction wheel 30 drives the workpiece 101 to rotate around the tooling 20, so that the friction wheel 30 and / or the workpiece 101 can grind the workpiece 101, thereby achieving the effect of grinding the workpiece 101 and improving the efficiency of grinding the workpiece 101; wherein the grinding of the workpiece 101 includes chamfering and / or deburring, etc.

[0072] In this embodiment, if Figures 4 to 6 As shown, the workpiece 101 is generally annular; for example, the workpiece 101 is a circular ring. The workpiece 101 has an axis in space. The through hole 102 extends along the axis of the workpiece 101 and is open at both ends of the workpiece 101. The workpiece 101 is a magnetic core.

[0073] In this embodiment, if Figures 1 to 6As shown, the tooling 20 is a columnar structure with an axis in space. When the workpiece 101 is placed on the tooling 20, the axis of the workpiece 101 is approximately parallel to the axis of the tooling 20. Along the axis of the tooling 20, the outer diameter of the tooling 20 gradually decreases and then gradually increases. When the workpiece 101 is placed outside the tooling 20, the tooling 20 contacts the inner walls of the through hole 102 at both ends, allowing the tooling 20 to grind the inner walls of the through hole 102 at both ends. The outer wall of the tooling 20 is curved, which facilitates surface wear of the workpiece 101 by the tooling 20. The tooling 20 is movably mounted on the machine body 10 and includes multiple workstations, namely a first workstation 23, a second workstation 231, a third workstation 232, and a fourth workstation 233. There is at least one tooling 20; for example, there can be one, two, three, four, five, or more tools 20. Preferably, the number of tooling 20 corresponds to the number of workstations; the tooling 20 can be located at different workstations. For example, there are four tooling 20, namely, a first tooling, a second tooling, a third tooling, and a fourth tooling. When the first tooling is located at the first workstation 23, the second tooling is located at the second workstation 231, the third tooling is located at the third workstation 232, and the fourth tooling is located at the fourth workstation 233. Alternatively, when the first tooling is located at the second workstation 231, the second tooling is located at the third workstation 232, the third tooling is located at the fourth workstation 233, and the fourth tooling is located at the first workstation 23. Alternatively, when the first tooling is located at the third workstation 232, the second tooling is located at the fourth workstation 233, the third tooling is located at the first workstation 23, and the fourth tooling is located at the second workstation 231. Alternatively, when the first tooling is located at the fourth workstation 233, the second tooling is located at the first workstation 23, the third tooling is located at the second workstation 231, and the fourth tooling is located at the third workstation 232.

[0074] In this embodiment, if Figures 1 to 6As shown, the automatic grinding machine 100 further includes a turntable 21 and a third driving member 22. The turntable 21 is rotatably mounted on the machine body 10, and the tooling 20 is mounted on the turntable 21. The first station 23, the second station 231, the third station 232, and the fourth station 233 are sequentially spaced along the circumference of the turntable 21. When the turntable 21 drives the tooling 20 to rotate, the tooling 20 switches between the first station 23, the second station 231, the third station 232, and the fourth station 233. The third driving member 22 can drive the turntable 21 to rotate. When the third driving member 22 drives the turntable 21 to rotate, the turntable 21 drives the tooling 20 to rotate around the rotation axis of the turntable 21, and the tooling 20 can switch between the first station 23, the second station 231, the third station 232, and the fourth station 233. Preferably, the third driving member 22 is an indexer, which is fixed to the body 10 by welding or bolts, and the rotating shaft of the indexer is connected to the geometric center of the turntable 21. The tooling 20 is connected to the turntable 21 by bolts or welding. The axis of the tooling 20 is arranged parallel to the rotation axis of the turntable 21.

[0075] In this embodiment, if Figures 1 to 8 As shown, the friction wheel 30 has a rotation axis in space; the rotation axis of the friction wheel 30 is parallel to the axis of the tooling 20; the outer periphery of the friction wheel 30 can contact the outer wall of the workpiece 101; when the friction wheel 30 rotates the workpiece 101, the rotation direction of the friction wheel 30 is opposite to that of the workpiece 101; the friction wheel 30 rotates the workpiece 101 through friction with the workpiece 101. Along the rotation axis of the friction wheel 30, the outer diameter of the friction wheel 30 gradually decreases and then gradually increases; when the friction wheel 30 is engaged with the workpiece 101 placed on the tooling 20, the friction wheel 30 contacts the outer walls of the workpiece 101 at both ends, and the friction wheel 30 can grind the outer walls of the workpiece 101 at both ends. The outer wall of the friction wheel 30 is curved, which facilitates surface wear of the workpiece 101 by the tooling 20. The choice of tooling 20 and friction wheel 30 can be determined based on the position of the workpiece 101 to be ground: for example, along the rotation axis of the friction wheel 30, the outer diameter of the friction wheel 30 gradually decreases and then gradually increases, and along the axis of the tooling 20, the outer diameter of the tooling 20 gradually decreases and then gradually increases; or, along the rotation axis of the friction wheel 30, the outer diameter of the friction wheel 30 gradually decreases and then gradually increases, and the tooling 20 is a cylindrical shape extending with equal diameters; or, the roller is a cylindrical shape extending with equal diameters, and along the axis of the tooling 20, the outer diameter of the tooling 20 gradually decreases and then gradually increases. Specifically, when the tooling 20 is in the second workstation 231, the friction wheel 30 can fit the workpiece 101 and drive the workpiece 101 to rotate.

[0076] In this embodiment, if Figures 1 to 8As shown, the automatic grinding machine 100 further includes a mounting base 31, a first driving member 32, and a second driving member 33. The friction wheel 30 is rotatably mounted on the mounting base 31. The first driving member 32 is mounted on the machine body 10 and can drive the mounting base 31 away from or toward the tooling 20. The second driving member 33 is mounted on the mounting base 31 and can drive the friction wheel 30 to rotate. When the workpiece 101 is placed on the tooling 20, the first driving member 32 drives the mounting base 31 and the friction wheel 30 toward the tooling 20 until the friction wheel 30 contacts the outer wall of the workpiece 101 and presses the workpiece 101 against the tooling 20. The second driving member 33 drives the friction wheel 30 to rotate, which in turn drives the workpiece 101 to rotate. The structure of the mounting base 31 is not strictly limited; it can simply support the second driving member 33 and the friction wheel 30. The first driving member 32 can drive the mounting base 31 to reciprocate, and the second driving member 33 can drive the friction wheel 30 to rotate. Preferably, the first driving member 32 is a cylinder, and the second driving member 33 is a motor. The cylinder comprises a cylinder body and a piston, which reciprocates along the cylinder body. The cylinder body is fixed to the machine body 10 by welding or bolts, and the piston is connected to the mounting base 31 by pins or bolts. The motor drives the friction wheel 30 via a gear train, and the motor is connected to the mounting base 31 by welding or bolts.

[0077] In this embodiment, if Figures 1 to 9 As shown, the automatic grinding machine 100 also includes a sensor 34 and a controller 35. The sensor 34 is used to detect the pressure between the friction wheel 30 and the workpiece 101. The sensor 34 sends the detected pressure signal to the controller 35, which controls the first driving member 32 based on the processed pressure signal. When the friction wheel 30 is in contact with the outer wall of the workpiece 101 and the workpiece 101 is pressed against the workpiece 101, the sensor 34 detects the pressure signal between the friction wheel 30 and the workpiece 101. The pressure sensor 34 sends the detected pressure signal to the controller 35, which controls the first driving member 32 based on the processed pressure signal. The first driving member 32 drives the friction wheel 30 to adjust the pressure between the friction wheel 30 and the workpiece 101. This allows the automatic grinding machine 100 to effectively grind workpieces 101 with different outer diameters and / or different inner diameters of through-holes 102. Both the controller 35 and the pressure sensor 34 utilize existing technologies; for example, the controller 35 is a single-chip microcomputer, and the sensor 34 is a pressure sensor.

[0078] In this embodiment, if Figures 1 to 6As shown, the automatic grinding machine 100 also includes a loading device 40, an unloading device 50, and a dust removal device 60.

The loading device 40 can automatically remove the workpiece 101 from the automatic grinding machine 100, thereby improving the loading efficiency of the automatic grinding machine 100. The dust removal device 60 can improve the working efficiency of the automatic grinding machine 100. When the tooling 20 is in the first workstation 23, the loading device 40 can transport the workpiece 101 to the tooling 20. After the loading device 40 places the workpiece 101 on the tooling 20, the turntable 21 rotates, and the workpiece 101 arrives at the second workstation 231. When the tooling 20 is in the third workstation 232, the unloading device 50 can remove the processed workpiece 101 from the tooling 20. After grinding at the second workstation 231, the workpiece 101 moves to the third workstation 232, where it is removed by the unloading device 50 and placed on an external conveyor belt or workbench.
