[0020] like Figure 1 As shown in Figure 4, the utility model provides a precision grinding machine tool, which includes a frame 1, a guide plate 2 is arranged on the frame 1, a plurality of workpiece placement grooves for placing workpieces are arranged on the guide plate 2, a grinding wheel assembly 3 is arranged on the frame 1 and placed on both sides of the guide plate 2, a grinding wheel 4 is arranged on the grinding wheel assembly 3, and the grinding wheel assembly 3 can drive the grinding wheel 4 to rotate, and the rotation speed of the grinding wheel 4 can be adjusted through the control system, and the feed amount of the grinding wheel 4 can be adjusted forward and backward, so as to grind the end face of the workpiece on the guide plate 2, and a guide assembly 5 for driving the guide plate 2 to rotate is also arranged on the frame 1, and the guide assembly 5 drives the guide plate 2 to rotate. The material disc 2 rotates to achieve uninterrupted workpiece end face grinding. In addition, a feeding assembly 8 and a pressing assembly 9 are installed on the material guide assembly 5. The feeding assembly 8 is connected to the pressing assembly 9. The external workpiece enters the material guide disc 1 through the feeding assembly 8, and the position of the workpiece is adjusted by the pressing assembly 9, and then the workpiece is transported to the grinding position. At the grinding position, the workpiece is pressed by the belt assembly 12 arranged on the frame 1 to perform grinding with a grinding wheel. The workpiece is placed on the material guide disc 2 stably and quickly through the feeding assembly 8, and the position of the workpiece on the material guide disc 2 is corrected by the pressing assembly 9 so that the position of the workpiece meets the end face grinding.

[0021] The precise feeding mechanism 6 includes a mounting plate 7 arranged on the material guide assembly 5 and placed on the inner side of the material guide disk 2, a feeding assembly 8 arranged on the mounting plate 7 and placed on the material guide disk 2, and a pressing assembly 9 arranged on the mounting plate 7, placed on the material guide disk 2, and docked with the feeding assembly 8; the pressing assembly 9 includes a pressing limiting plate 10 arranged on the mounting plate 7, placed on the material guide disk 2, and having a circular arc bottom surface, and a pressing outer limiting plate 11 arranged on the mounting plate 7 and placed on the outer side of the material guide disk 2. The precise feeding mechanism 6 is installed on the material guide assembly 5 on the inner side of the material guide disk 2 through the mounting plate 7, and guides the workpiece onto the material guide disk 2 through the feeding assembly 8 arranged on the mounting plate 7, and then adjusts the position of the workpiece through the pressing assembly 9, specifically, the position adjustment of the workpiece is achieved through the cooperation of the pressing limiting plate 10 and the pressing outer limiting plate 11, so as to facilitate the end face grinding of the workpiece later.

[0022] like Figure 2As shown, the feed assembly 8 includes an inner feed limit plate 13 arranged on the mounting plate 7 and placed on the inner side of the guide disk 2, an outer feed limit plate 14 arranged on the mounting plate 7 and placed on the outer side of the guide disk 2, and an upper guide plate 15 and a lower guide plate 16 arranged on the mounting plate 7 and placed on both sides between the inner feed limit plate 13 and the outer feed limit plate 14 to form a feed port 17. The feed assembly 8 is docked with the external loading assembly, and the loading assembly loads the workpiece to the feed port 17 of the feed assembly 8. The feed assembly 8 introduces the workpiece through the feed port 17, and limits the position of the workpiece in the feed assembly 8 through the inner feed limit plate 13 and the outer feed limit plate 14, so that the workpiece falls accurately onto the guide plate 2, and then the guide plate 2 drives the workpiece into the pressing assembly 9. The size of the feed port 17 can be controlled by the width and thickness of the upper guide plate 15 and the lower guide plate 16 to achieve grinding processing of workpieces of different diameters and lengths.

[0023] The inner limit plate 13 and the outer limit plate 14 of the feed are in an inner step arc shape on the surface opposite to the guide plate 2, and are the same as the arc surface of the guide plate 2; the inner limit plate 13 and the outer limit plate 14 of the feed are in the same structure, and the bottom of the main body is in an arc shape; the front end of the bottom of the upper guide plate 15 is in an arc shape; the bottom surfaces of the upper guide plate 15 and the lower guide plate 16 are in an arc structure, and fit the arc surface of the guide plate 2. The inner limit plate 13 and the outer limit plate 14 of the feed are set in this structure because the length of the workpiece is slightly larger than the thickness of the guide plate 2, so the inner limit plate 13, the outer limit plate 14 of the feed are set in an inner step arc shape on the surface opposite to the guide plate 2 to meet the workpiece entering the guide plate, the bottom of the main body is in an arc shape to cater to the guide plate 2, so that the overall look is more beautiful and coordinated, and the front end of the bottom of the upper guide plate 15 is in an arc shape to prevent scratches on the workpiece.

[0024] This type of feed assembly is suitable for processing workpieces with a length greater than 3 cm and a diameter greater than 1 cm.

[0025] like Figure 4As shown, the feeding assembly 8 includes a feeding guide block 18 provided on the mounting plate 6, with an inclined top surface and an arc-shaped bottom surface, a feeding adjustment block 19 provided on the feeding guide block 18, and a feeding guide pipe 20 provided on the feeding adjustment block 19 and passing through the feeding adjustment block 19. The feeding adjustment block 19 is provided with an adjustment slide groove 21 for adjusting the feeding adjustment block 19. The feeding guide block 18 is installed on the mounting plate 7. The bottom surface is arc-shaped in order to better fit the guide disk 2. The top is made into an inclined surface to allow the workpiece to slide onto the guide disk 2 with its own weight. The feeding adjustment block 19 is installed on the feeding guide block 18 to provide an installation position for the guide tube 20. In addition, an adjustment slot 21 is provided on the feeding adjustment block 19 to adjust the position of the feeding adjustment block 19 and further adjust the position of the guide tube 20 so that the bottom end of the outlet of the guide tube 20 is on the same horizontal plane with the contact surface of the feeding guide block 18, thereby allowing the workpiece to slide smoothly onto the feeding guide block 18.

[0026] This feeding assembly is suitable for processing workpieces with a length greater than 1 cm and less than 3 cm and a diameter greater than 2 mm and less than 1 cm.

[0027] The main body of the outer limit plate 11 of the press is in the shape of an arc; the surface opposite to the guide plate 2 of the outer limit plate 11 of the press is in the shape of an inner step arc, and the front end has a feed slope (not shown in the figure); the surface of the outer limit plate 11 of the press and the grinding wheel 4 is in the shape of an arc. The outer limit plate 11 of the press is set in this structure because when the workpiece is ground, the length of the workpiece is slightly greater than the thickness of the guide plate 2, so it is necessary to set the surface opposite to the guide plate 2 of the outer limit plate 11 of the press to an inner step arc, leaving enough space for the workpiece to meet the grinding requirements of the workpiece, and the front ends of the inner limit plate 10 and the outer limit plate 11 of the press are provided with a feed slope in order to adjust the position of the workpiece to the best grinding position, and the inner limit plate 10 and the outer limit plate 11 of the press and the grinding wheel 4 have an arc surface in order to facilitate the connection with the grinding wheel 4 and effectively prevent the position of the workpiece from changing.

[0028] This kind of precise feeding mechanism can meet the feeding needs of various centimeter-level workpieces. In addition, this kind of precise feeding mechanism has a simple structure, low cost and good feeding effect.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
