Description

Technical Field

[0001] The utility model relates to the field of milling and grinding equipment, in particular to an automatic milling and grinding all-in-one machine. Background Art

[0002] Steel milling and grinding is the pre-process of metal cutting. The traditional processing method is to process steel through a set of milling and grinding equipment formed by a double-head milling machine, a gantry milling machine and a grinder. This type of milling and grinding equipment generally uses a motor to drive the grinding wheel to rotate through a pulley assembly to mill the workpiece. Since the motor and the grinding wheel are located on the same side and opposite to each other, this type of milling and grinding equipment has a relatively narrow distance between the motor and the grinding wheel. It is only suitable for installing grinding wheels with a width of 50-75mm. The milling and grinding efficiency of this wide range of grinding wheels needs to be greatly improved. At the same time, although the traditional milling and grinding equipment can realize milling and grinding of workpieces, its function is relatively single. After replacing the grinding wheels of different specifications, it needs to manually trim the grinding wheels, resulting in low work efficiency, high labor intensity of workers and high labor costs of enterprises.

[0003] Later, some integrated milling and grinding machines appeared on the market, which used abrasive belts to mill workpieces. Since the length of the abrasive belt is wider than the grinding wheel, it can improve the milling efficiency of the workpiece. However, the disadvantage of using abrasive belts to mill workpieces is that the abrasive belts are easy to wear, and the worn abrasive belts cannot be repaired, resulting in the abrasive belts being unsuitable for milling high-precision workpieces. It has problems such as high frequency of abrasive belt replacement, high cost of abrasive belt use, and poor processing accuracy of workpieces. In addition, although the current integrated milling and grinding machines can mill workpieces, they do not have a structure that can automatically measure the rough material size of the workpiece (i.e., the height of the workpiece before milling) and the semi-finished material size of the workpiece (i.e., the height of the workpiece before grinding), resulting in the inability to automatically formulate a plan for milling the workpiece based on the rough material size of the workpiece, the semi-finished material size of the workpiece, and the size of the workpiece to be processed (i.e., the fine material size of the workpiece), thereby resulting in the inability to achieve automated intelligent production.

[0024] Preferably, the automatic milling and grinding machine can be installed with a grinding wheel with a width of 50-150 mm.

[0025] By adopting the above technical solution, since traditional milling machines or grinders can only install grinding wheels with a width of 50-75mm due to the structure of the driving source, when they perform milling and grinding on workpieces of the same size, the processing efficiency of this product with a grinding wheel with a width of 50-150mm is more than twice that of traditional milling machines or grinders with a grinding wheel width of 50-75mm, so that the grinding efficiency of the grinding wheel can be greatly improved.

When the grinding head spindle 61 is installed with grinding wheels 62 of different specifications according to the processing needs, the first tool setting instrument 11 can contact the grinding wheel 62 with the magnetic disk 9 and driven by the displacement mechanism 2 to automatically measure the diameter, thickness and other parameters of the grinding wheel 62, and automatically feed back the measured parameters to the control system. After receiving the parameters fed back by the first tool setting instrument 11, the control system can automatically formulate a dressing plan and send commands to the displacement mechanism 2, the fourth screw drive module 24 and the grinding head spindle motor 63 respectively. The grinding wheel repair pen 10 can automatically move to the middle of the grinding wheel 62 after being displaced in the X and Y directions with the magnetic disk 9 and driven by the displacement mechanism 2. , the grinding wheel 62 is driven down by the fourth screw transmission module 24, the grinding wheel dressing pen 10 is driven by the displacement mechanism 2 and the grinding wheel 62 is driven by the fourth screw transmission module 24 until the grinding wheel dressing pen 10 is aligned with and in contact with the center of the grinding wheel 62, when the grinding wheel 62 rotates under the drive of the grinding head spindle motor 63, the grinding wheel dressing pen 10 can automatically dress the grinding wheel 62 that is in contact and rotating therewith, so as to realize automatic dressing of the grinding wheel 62; after the grinding wheel dressing pen 10 completes dressing of the grinding wheel 62, the first tool setting instrument 11 measures the dressed grinding wheel 62 again according to the aforementioned method, and automatically compensates the parameters measured after dressing to the control system, so as to reduce the dressing error to a minimum, so that it can greatly improve the accuracy of the grinding wheel 62 in the later stage of workpiece processing.

[0069] A milling head measuring module 7 is provided on the side of the milling head spindle 51 and a grinding head measuring module 8 is provided on the side of the grinding head spindle 61. Before the milling head cutter disc 52 processes the workpiece placed on the magnetic disk 9, the milling head measuring module 7 first descends to the surface of the workpiece to automatically measure the rough material size of the workpiece (i.e., measure the height of the workpiece before milling), and automatically feeds back the measured rough material size to the control system. The control system receives the rough material size fed back by the milling head measuring module 7 and automatically formulates a milling processing plan in combination with the fine material size of the workpiece input by the operator before production. Then, the control system sends driving commands to the third screw drive module 23 and the milling head spindle motor 53 respectively according to the formulated milling processing plan, so that the milling head cutter disc 52 descends to the surface of the workpiece under the drive of the third screw drive module 23. At the same time, the milling head spindle motor 53 drives the milling head cutter disc 52 to rotate to perform high-precision milling processing on the workpiece, which ensures that the milling processing accuracy of the milling head cutter disc 52 is high and the milling processing effect is good. When the milling head cutter 52 completes the milling process on the workpiece, the workpiece that has completed the milling process is transferred to the processing station of the grinding wheel 62 along with the magnetic disk 9 and driven by the displacement mechanism 2, and the grinding wheel 62 starts to grind the workpiece. The working principle of the grinding head measurement module 8 is the same as the working principle of the milling head measurement module 7. The difference is that the grinding head measurement module 8 automatically measures the semi-finished material size of the workpiece (that is, measures the height of the workpiece before grinding), and the grinding wheel 62 descends to the surface of the workpiece under the drive of the fourth screw transmission module 24. At the same time, the grinding head spindle motor 63 drives the grinding wheel 62 to rotate to perform high-precision grinding on the workpiece. After the workpiece is processed, the workpiece is reset along with the magnetic disk 9 and driven by the displacement mechanism 2 to move away from the grinding wheel 62, so as to facilitate the unloading of the workpiece that has completed the processing on the magnetic disk 9 and to facilitate the loading of the next workpiece to be processed onto the magnetic disk 9.

[0070] Its overall structural design enables a single device to have functions such as automatic grinding wheel 62 dressing, automatic compensation, automatic workpiece measurement, automatic milling and automatic grinding, and it can automatically compensate the measured parameters and the trimmed parameters to the control system through the use of the first tool setting instrument 11 and the grinding wheel dressing pen 10, so that it can automatically complete the dressing of the grinding wheel 62 according to the grinding wheel 62 of different sizes, so as to solve the problem that the traditional milling and grinding equipment and the current milling and grinding machine need to manually dress the grinding wheel 62 after replacing the grinding wheel 62. At the same time, it uses the milling head cutter disc 52 with the milling head measurement module 7 and the grinding wheel 62 with the grinding head measurement module 8 to ensure that the milling head cutter disc 52 and the grinding wheel 62 have high processing accuracy and good processing effect, and realizes automated and intelligent production, so as to solve the problem that the current milling and grinding machine cannot automatically formulate a milling processing plan according to the rough material size and fine material size of the workpiece, resulting in its inability to realize intelligent production. In addition, it can be installed with a grinding wheel 62 with a wider size range (50-150mm), so that it can greatly improve the processing efficiency of the grinding wheel 62, so as to solve the problem that traditional milling and grinding equipment can only be installed with a grinding wheel 62 with a width of 50-75mm, resulting in low grinding efficiency.
