Specific implementation manner

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figures 1 - 6 shown, a technical solution provided by the present utility model:

[0028] A grinding device for machining metal workpieces, including a base plate 1, two mounting frames 2 are symmetrically arranged at the upper end of one side of the base plate 1, a flipping frame 3 is movably installed between the upper ends of the two mounting frames 2, clamping mechanisms are arranged on both sides of the flipping frame 3, the clamping mechanisms include a first clamping cylinder 11, the first clamping cylinder 11 is fixedly installed inside both sides of the flipping frame 3, a clamping plate 12 is arranged at the output shaft end of the first clamping cylinder 11, a frame 5, the frame 5 is arranged outside the same side of the base plate 1 close to the two mounting frames 2, a servo slide table module 6 is arranged at the top of the frame 5, a grinding mechanism is arranged below the servo slide table module 6, the grinding mechanism includes a support plate 7, the support plate 7 is movably installed below the servo slide table module 6, a second electric push rod 8 is arranged at the upper end of the other side of the support plate 7, a motor 9 is arranged at the output shaft end of the second electric push rod 8, and a grinding wheel 10 is fixedly connected to the output shaft end of the motor 9;

[0029] In this embodiment, since the lower end surface of the workpiece is horizontal with the surface of the flipping frame 3, it is necessary to start the clamping cylinder 11 and the clamping cylinder 13. The clamping cylinder 11 controls the clamping plate 12 to retract, while the clamping cylinder 13 drives the wedge 14 to push forward. In this way, the upper end surface of the workpiece can be pushed to be horizontal with the flipping frame 3, and the lower end surface is exposed. In this way, when placing the workpiece, the surface to be polished can be exposed, and after flipping, it can be automatically adjusted.

[0030] As Figure 2 and Figure 6 shown, the electric push rod 4 is arranged outside the bottom plate 1 near the right flipping frame 3. A flipping mechanism is arranged between the electric push rod 4 and the right flipping frame 3. The flipping mechanism includes a gear 15. The right end of the flipping frame 3 passes through the right mounting frame 2 and is fixedly installed with the gear 15. The output shaft end of the electric push rod 4 is provided with a fixing strip 17. One side of the fixing strip 17 is fixedly installed with a mounting strip 18 through bolts. The front surface of the mounting strip 18 is provided with a rack 19 meshing with the gear 15. A guide frame 20 is horizontally arranged on the side of the right mounting frame 2 away from the rack 19. A guide rod 16 movably connected with the guide frame 20 is vertically arranged on the left side of the fixing strip 17. Two clamping cylinders 13 are arranged outside the lower part of the mounting frames 2 near the flipping frame 3. The output shaft end of the clamping cylinder 13 is fixedly connected with a wedge 14;

[0031] In this embodiment, after the upper end surface of the workpiece is polished, the wedge 14 and the grinding wheel 10 are retracted, and the electric push rod 4 is started. After the electric push rod 4 is started, the rack 19 is lifted through the fixing strip 17 and the mounting strip 18. The rack 19 controls the gear 15 to rotate. After the gear 15 rotates, it drives the flipping frame 3 to flip 180°. When it is necessary to replace the worn gear 15 and rack 19 later, it is more convenient. The mounting strip 18 can be disassembled from the fixing strip 17, and then the gear 15 can be disassembled, so as to achieve the purpose of convenient maintenance.

[0032] Working principle: When grinding a metal workpiece, start the clamping cylinder II 13. The clamping cylinder II 13 controls the inclined block 14 to push forward and support on both sides below the flipping frame 3. Then place the workpiece in the flipping frame 3 and control the clamping plate 12 to clamp and fix it through the clamping cylinder I 11. Then start the electric push rod II 8 and the motor 9. The electric push rod II 8 controls the motor 9 to descend. The motor 9 drives the high-speed rotating grinding wheel 10 to grind the upper end face of the workpiece. And during the grinding process, the grinding wheel 10 can also be controlled to move horizontally by the servo slide table module 6 to complete the grinding of the upper end face of the workpiece at one time. After the upper end face of the workpiece is ground, retract the inclined block 14 and the grinding wheel 10, and start the electric push rod I 4. After the electric push rod I 4 is started, it drives the rack 19 to lift through the fixing strip 17 and the mounting strip 18. The rack 19 controls the gear 15 to rotate. After the gear 15 rotates, it drives the flipping frame 3 to flip 180°, so that the lower end face of the workpiece faces upward. Since the lower end face of the workpiece is horizontal with the surface of the flipping frame 3, it is necessary to start the clamping cylinder I 11 and the clamping cylinder II 13. The clamping cylinder I 11 controls the clamping plate 12 to retract, and the clamping cylinder II 13 drives the inclined block 14 to push forward. In this way, the upper end face of the workpiece can be pushed to be horizontal with the flipping frame 3, and the lower end face is exposed. Then control the clamping plate 12 to clamp the workpiece through the clamping cylinder I 11, and then grind the lower end face of the workpiece again.
