[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] A fully automatic grinding machine for grinding six sides of hexagonal parts, such as Figure 1 and Figure 2 The system includes a grinding machine body 1 and a worktable 11 mounted on the grinding machine body 1. An L-shaped support plate 12 is mounted on the worktable 11. A rotating plate 121 is rotatably connected to the vertical surface of the support plate 12. An electromagnetic chuck 122 is mounted on the side of the rotating plate 12 facing away from the vertical surface of the support plate 12. A power component for driving the rotating plate 121 to rotate is mounted on the support plate 12. The worktable 11 can move along the XY axes on the grinding machine body 1 using existing structures, which will not be described in detail here.

[0026] like Figure 1 and Figure 2The workpiece is placed on the electromagnetic chuck 122. At this time, the surface of the workpiece to be processed is higher than the upper surface of the electromagnetic chuck 122, which facilitates the processing by the grinding machine. The surface processed at this time is called the first surface, which is the reference surface. The workpiece is removed from the electromagnetic chuck 122, and the first surface is attached to the electromagnetic chuck 122. The two intersecting surfaces, the second surface and the third surface, which are perpendicular to the first surface, are released from the outer wall of the electromagnetic chuck 122. The grinding machine processes the second surface first, and then the power component drives the rotating plate 121 to rotate 90° to facilitate the processing of the third surface, thereby facilitating the processing of workpieces with mutually perpendicular surfaces.

[0027] like Figure 1 and Figure 2 and Figure 5 The power component includes a DD motor 123 mounted on the vertical surface of the support plate 12. The DD motor 123 is a direct drive motor, which has unique characteristics such as low speed, high torque, simple structure, reduced mechanical loss, low noise, and low maintenance. The rotating plate 121 is fixed on the rotor of the DD motor 123. At this time, the rotating plate 121 is driven to rotate by the DD motor 123.

[0028] like Figure 1 and Figure 2 and Figure 5 A rotary plate 121 has a rotary cylinder 124 on one side of the electromagnetic chuck 122. The piston rod of the rotary cylinder 124 has a horizontal bar 125 parallel to the surface of the electromagnetic chuck 122. At the end of the horizontal bar 125 away from the piston rod of the rotary cylinder 124, there is a pressure rod 126 parallel to the piston rod of the rotary cylinder 124. At the end of the pressure rod 126 facing the electromagnetic chuck 122, there is a pressure block 127. When the workpiece is attracted to the electromagnetic chuck 122, the piston rod of the rotary cylinder 124 rotates towards the workpiece while pressing the workpiece, providing a compressive force to the workpiece, thereby improving the stability of the workpiece during grinding. The rotary cylinder 124 is positioned away from the grinding wheel 162 on the grinding machine body 1. One end of the pressure rod 126 has a connecting rod (not shown in the figure) that enters the horizontal bar 125 and is threadedly connected to the horizontal bar 125, facilitating the replacement and disassembly of the pressure rod 126.

[0029] like Figure 2 and Figure 3 and Figure 4 A sleeve 13 is fixed on the side of the rotating plate 121 away from the electromagnetic chuck 122. The sleeve 13 is fitted on the outer wall of the DD motor 123. A protective cover 131 is provided on the vertical surface of the support plate 12, covering the outer wall of the sleeve 13 away from the rotating plate 121. The sleeve 13 rotates inside the protective cover 131 as the rotating plate 121 rotates. At this time, the sleeve 13 and the protective cover 131 protect the DD motor 123 and reduce water ingress. The sleeve 13 has an annular retaining ring 132 on the outer wall inside the protective cover 131. The retaining ring 132 further reduces water ingress into the DD motor 123. The protective cover 131 has an arc-shaped opening that matches the outer wall of the sleeve 13.

[0030] like Figure 2 and Figure 3 and Figure 4 The upper side wall of the protective cover 131 is provided with an inclined surface 14 that bends towards the sleeve 13. The inclined surface 14 is located on the side of the retaining ring 132 facing the rotating plate 121. The inclined surface 14 reduces the gap between the inner wall of the upper end of the protective cover 131 and the outer wall of the sleeve 13, reducing the amount of water entering the DD motor 123. The sleeve 13 is provided with a connecting plate 15 that is bolted to the rotating plate 121. A sealing gasket is provided between the connecting plate 15 and the rotating plate 121. The sealing gasket further reduces water seepage into the sleeve 13.

[0031] like Figure 1 and Figure 6 A column 16 is provided on one side of the grinding machine body 1. A slide plate 161 is slidably connected to the column 16 in the vertical direction. A grinding wheel 162 is rotatably connected to the slide plate 161. A motor is provided on the slide plate 161 to drive the grinding wheel 162 to rotate. At this time, the vertical sliding of the slide plate 161 on the column 16 can be driven by a motor screw module, which is an existing structure and will not be described in detail here. The vertical surface of the support plate 12 is distributed close to the column 16. A housing 163 is provided on the side of the slide plate 161 and the grinding wheel 162. A fixing block 164 is slidably connected to the inner wall of the housing 163 in the vertical direction. A wired probe 165 for measuring the height of the workpiece surface is provided on the fixing block 164. A cylinder 166 for driving the fixing block 164 to slide up and down is provided inside the housing 163. An opening is provided at the lower end of the housing 163 for the wired probe 165 to slide out.

[0032] like Figure 1 and Figure 2 and Figure 6 After the workpiece has been ground to the third side, in order to continue grinding the remaining three sides, the workpiece is removed from the electromagnetic chuck 122, with the third side facing the grinding wheel 162. The fourth side to be processed extends beyond the edge of the electromagnetic chuck 122. Through the movement of the XY axes of the worktable 11 and the movement of the slide plate 161 on the column 16, the wired probe 165 moves out of the opening and closer to the workpiece. The cylinder 166 drives the wired probe 165 to move, as well as the XY axes of the worktable 11 and the slide plate 161 to move. The movement of plate 161 on column 16 causes wired probe 165 to measure several points on the third surface of the workpiece. If the height of the measured points is the same, it indicates that the third surface is horizontal. At this time, rotating plate 121 rotates 90° so that the fourth surface faces grinding wheel 162. Wired probe 165 extends into the opening, and grinding wheel 162 grinds the fourth surface of the workpiece. This ensures the perpendicularity of the fourth surface and the third surface. If the height of the measured points is different, rotating plate 121 can be rotated to make the third surface horizontal.

[0033] like Figure 1 and Figure 2 and Figure 6 After the fourth side is processed, the workpiece is removed so that the fourth side faces upward. The fifth side to be processed extends out of the edge of the electromagnetic chuck 122. At this time, both the fourth and fifth sides extend out of the edge of the electromagnetic chuck 122. The work of the wired probe 165 is repeated to make the fourth side horizontal. Then the rotating plate 121 is rotated so that the fifth side faces upward, thereby ensuring the perpendicularity of the fifth and fourth sides. The grinding wheel 162 processes the fifth side. At this time, all four sides perpendicular to the first side are ground.

[0034] like Figure 1 and Figure 2 and Figure 6 After the fifth side is processed, the workpiece is removed, and the second side is attached to the electromagnetic chuck 122, so that the third and sixth sides extend beyond the edge of the electromagnetic chuck 122. At this time, the third side is facing upwards. The operation of the wired probe 165 is repeated to make the third side horizontal. Then, the rotating plate 121 is rotated to make the sixth side facing upwards, thus ensuring the perpendicularity of the sixth side and the third side. The grinding wheel 162 grinds the sixth side. At this time, the sixth side and the first side are parallel to each other. After the grinding wheel 162 finishes grinding the sixth side, all six sides of the hexagon are ground. The process is highly accurate, saves time, and is simple to operate.

[0035] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
