The limiting component 532 is located between the movable base 7 and the placement assembly 3, and when the movable base 7 is driven by the operating part 6, When the placement assembly 3 is moved by a predetermined distance, the limiting component 532 will abut against the movable base 7 to prevent the movable base 7 from moving excessively, and the grinding head 81 interferes with the workpiece A. Therefore, when the grinding is to be performed, the first moving component 421 may be moved to a certain position, wherein the moving amount is the distance from the polishing head 81 to the central hole A1 minus the predetermined distance, and then the second movement is operated. The assembly 422 is moved downward to perform the grinding operation. In this way, when a large number of the workpiece A of the same size is to be ground, the user can perform the grinding by repeating the movement of the second moving component 422 after the first adjustment, thereby effectively improving the processing efficiency. More preferably, the limiting component 532 has a connecting base 533 and a limiting member 534 movably disposed on the connecting base 533. The two ends of the connecting base 533 are respectively connected to the base 53 and the limiting member. 534, the limiting member 534 is selectively abutted against the movable seat 7, and the limiting member 534 can be used to adjust the predetermined distance by matching the workpiece A of different sizes. In other embodiments, the connector 533 is regarded as a part of the pedestal 53 and is also indispensable.

It is to be noted that the center hole grinding machine 1 preferably further includes a positioning mechanism 9 for positioning the workpiece A. The positioning mechanism 9 is disposed on the frame 2, and the positioning mechanism 9 is located. The placement assembly 3 is between the polishing assembly 4. It can be understood that the positioning mechanism 9 is preferably connected to the frame 2 in an up-and-down manner, and can further adjust the length of the workpiece A to adjust a suitable positioning height to ensure that the workpiece A is not generated by the grinding process. The vibration is deflected or dumped. More specifically, the positioning mechanism 9 includes a body 91 having an opening 92 and at least one positioning component 93 disposed on the body 91. At least one of the positioning components 93 is disposed at the end of the opening 92 and can open toward the opening. Rotate in 92 directions. The operation method of positioning in detail is as follows. First, the centering hole A1 of the workpiece A is clamped up and down by the placement assembly 3 and the polishing head 81 to position the axial reference of the workpiece A, and then The positioning assembly 93 is fixed to the workpiece A by laterally abutting.

In summary, the center hole grinding machine of the present invention has a second moving mechanism having two first and second moving components of different moving modes, and the first moving component is actuated by a screw, so that it has the characteristics of continuous fine adjustment, and The two moving components have the characteristics of rapid feeding by the cooperation of the fixing member and the elastic member. Since the grinding mechanism is disposed on the second moving component, the grinding head can be quickly moved to the center hole of the workpiece, thereby effectively reducing the moving time.

Moreover, the second moving component is matched with the finite component. When a large number of workpieces of the same size are required to be ground, only the first machining process is performed, the displacement of the grinding head in the vertical direction is adjusted, and then the limiting member is passed through. The predetermined distance is set to the displacement stroke, and the subsequent machining operation can directly use the second moving component to drive the grinding head to grind the center hole of the workpiece, thereby greatly improving the production capacity and saving the working time.
