[0013] like Figure 1 As shown, the utility model provides a precision grinding machine tool, which includes a frame 1, a material guide assembly 5 arranged on the frame 1, a material guide disc 2 arranged on the material guide assembly 5, the material guide disc 2 is circular, and the material guide disc 2 is provided with a plurality of workpiece placement grooves for placing workpieces, a grinding wheel assembly 3 arranged on the frame 1 and placed on both sides of the material guide disc 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 control system can be used to adjust the rotation speed of the grinding wheel 4, and the feed amount of the grinding wheel 4 can be adjusted forward and backward, so as to grind the end surface of the workpiece on the material guide disc 2, and the grinding wheel assembly 3 can be used to drive the grinding wheel 4 to rotate. The frame 1 is also provided with a material guide component 5 for driving the material guide disc 2 to rotate. The material guide component 5 drives the material guide disc 2 to rotate to achieve uninterrupted workpiece end face grinding. A precise feeding mechanism 6 is installed on the material guide component 5. The workpiece is introduced into the material guide disc 2 through the precise feeding mechanism 6. In addition, a material pressing component 9 is also installed on the material guide component 5. The material pressing component 9 is docked with the precise feeding mechanism 6, so that the workpiece enters the material pressing component 9 from the precise feeding mechanism 6, and then the material pouring component 5 drives the material guide disc 2 to rotate, and then the material pressing component 9 is used to realize stable and rapid correction of the position of the workpiece on the material guide disc 2, so that the position of the workpiece meets the end face grinding.
[0014] like Figure 2As shown, the precise feeding mechanism 6 includes a mounting plate 7 arranged on the material guide component 5 and placed on the inner side of the material guide disk 2, and a feed component 8 arranged on the mounting plate 7 and placed on the material guide disk 2; the feed component 8 includes an inner feed limit plate 13 arranged on the mounting plate 7 and placed on the inner side of the material guide disk 2, an outer feed limit plate 14 arranged on the mounting plate 7 and placed on the outer side of the material guide disk 2, and an upper material guide plate 15 and a lower material guide plate 16 arranged on the mounting plate 7, placed on both sides between the inner feed limit plate 13 and the outer feed limit plate 14, and forming 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 realize the loading of workpieces of different diameters and lengths.
[0015] The surfaces opposite to the guide plate 2 of the inner limit plate 13 and the outer limit plate 14 are in an inner step arc shape, and are the same as the arc surface of the guide plate 2; the inner limit plate 13 and the outer limit plate 14 have the same structure, and the bottom of the main body is in a circular arc shape; the front end of the bottom of the upper guide plate 15 is in a circular arc shape; the bottom surfaces of the upper guide plate 15 and the lower guide plate 16 are in an arc-shaped structure, and fit with the arc surface of the guide plate 2. The inner feed limit plate 13 and the outer feed limit plate 14 are set to this structure because the length of the workpiece is slightly larger than the thickness of the guide plate 2. Therefore, the inner feed limit plate 13, the outer feed limit plate 14 and the opposite surfaces of the guide plate 2 are set to an inner step arc shape to leave enough accommodating space for the workpiece to meet the needs of the workpiece entering the guide plate. The bottom of the main body is arc-shaped to cater to the guide plate 2, making the overall look more beautiful and coordinated. The front end of the bottom of the upper guide plate 15 is arc-shaped to prevent scratches on the workpiece.
[0016] The material pressing assembly 9 includes an inner material pressing limit plate 10 arranged on the mounting plate 7 and placed on the inner side of the material guide disk 2, an outer material pressing limit plate 11 arranged on the mounting plate 7 and placed on the outer side of the material guide disk 2, and a material pressing sheet 12 arranged on the mounting plate 7, placed between the inner material pressing limit plate 10 and the outer material pressing limit plate 11, and having an arc-shaped bottom surface that fits the arc surface of the material guide disk 2. The pressing component 9 is installed on the material guide component 5 on the inner side of the material guide disc 2 through the mounting plate 7. The pressing component 9 adjusts the position of the workpiece, specifically through the cooperation of the inner limiting plate 10 and the outer limiting plate 11. The workpiece is limited on the material guide disc 2 by the pressing piece 12 installed between the inner limiting plate 10 and the outer limiting plate 11. Since the material guide disc 2 is a circular structure, the pressing piece 12 is made into an arc structure and fits with the arc surface of the material guide disc 2, so as to better press the workpiece on the material guide disc 2, so as to facilitate the end face grinding of the workpiece later. By pressing the workpiece in the form of a sheet 12, millimeter-level workpiece end face grinding can be achieved, because the sheet 12 can be made into a millimeter level and its performance can be guaranteed. The sheet 12 can be a metal part or a non-metal part. Metal parts such as steel materials, alloy materials, etc., non-metal parts such as glass fiber composite boards, bakelite, nylon, etc., as long as the material can meet sufficient pressing strength, it can be used. Since the thickness limitation of the sheet 12 is relatively low, not only can the grinding of thin parts with a thickness of 1-10mm and a diameter of 2-30mm be achieved, but also the grinding of centimeter-level workpieces can be achieved.
[0017] The inner limit plate 10 and the outer limit plate 11 have the same structure and the main body is in an arc shape; the inner limit plate 10 and the outer limit plate 11 have an inner step arc shape on the surface opposite to the guide plate 2, and the front end has a feed slope (not shown in the figure); the inner limit plate 10 and the outer limit plate 11 have an arc surface on the surface opposite to the grinding wheel 4. The inner limit plate 10 and the outer limit plate 11 of the material pressure press are set to this structure because when the workpiece is ground, the length of the workpiece is slightly larger than the thickness of the guide disk 2. Therefore, the inner limit plate 10, the outer limit plate 11 and the opposite surface of the material guide disk 2 need to be set to an inner step arc shape to leave enough accommodating space for the workpiece to meet the grinding requirements of the workpiece, and the front end of the inner limit plate 10 and the outer limit plate 11 are provided with a feed slope in order to adjust the position of the workpiece to the optimal grinding position, and the inner limit plate 10, the outer limit plate 11 and the grinding wheel 4 have an arc surface to facilitate the connection with the grinding wheel 4 and effectively prevent the position of the workpiece from changing.
[0018] The pressing piece 12 is semicircular and its thickness is less than or equal to the thickness of the material guide disc 2. The pressing piece 12 is made into a semicircular shape so as to fit with the disc surface of the material guide disc 2 and better press the workpiece onto the material guide disc 2, and the thickness is less than or equal to the thickness of the material guide disc 2 so as not to hinder the grinding of the workpiece and ensure that the pressing piece 12 has sufficient pressing performance. When the thickness is less than the thickness of the material guide disc, the thickness slightly less than the thickness of the material guide disc 2 can be selected. Therefore, no matter what thickness of the pressing piece 12 is used, as long as it can ensure sufficient pressing performance.
[0019] The press-feeding mechanism 6 also includes a fixing column (not shown) disposed on the frame 1 and placed at the bottom of the guide plate 2 for fixing the press sheet 12. The fixing column is provided to fix the other end of the press sheet 12 so that the press sheet 12 can better press the workpiece onto the guide plate 2.
[0020] This type of precise feeding mechanism controls the size of the feed port through the cooperation of the inner feed limit plate, the outer feed limit plate, the upper guide plate and the lower guide plate, thereby realizing the feeding of thin-sheet workpieces of any size. In addition, this type of precise feeding mechanism has a simple structure, low cost and good feeding effect.
[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
