X, in step 3, 11, because the beam 92 has been securely fixed to the positioning grooves, the load nut 442 of the 5 shank 44 has no need to reload the weight of the 200909124 (four) 92 and the U axis, plus The length of the driven rod (4) is longer than the length of the driving hole 421, so the rod 44 = the end 441 having the load nut 442 will also gradually rise and approach the U 45 ' until the load screw The cap 442 touches the sensor C, as shown in FIG. After the sensor 45 is triggered, a signal is sent. Step 7: The signal stops the driving of the power source 41. Through the reduction gear 42, the rod 44 also stops rotating and does not continue to rise. Thus, the opposite of the height reduction of the beam 92 along the axial direction L is completed. 'If the crosspiece 92 is an action of ascending along the axial direction', the power source 41 in the above step drives the rod (1) to rotate in the other direction to raise the beam 92. f, it is worth noting that when the beam 92 is to be again along the axial direction, the power source 41 must drive the rod to rotate in the other direction. The load nut 442 is pressed against the reduction gear box, so that the load nut is again used to lift the beam % and the weight of the machining spindle, and then the actuators 322 are respectively pulled back to the positioning slot buckles. The locating pins 32 can perform the up or down movement of the lower beam once again. According to the above description, the beam positioning device 2 and the method of the machine tool of the present invention are respectively engaged with the positioning grooves 311 'located on the β-column 91 by the positioning locks 321 provided on the beam 92. The beam % can be preliminarily fixed to the column 91 ' along the axial direction L and because the rod 44 screwed to the beam V continuously rotates, a force can be applied to the beam 92 to make the positioning lock 321 The lower edge of the lower edge is fixed in the positioning groove 311. For example, 10 200909124, the beam 92 is well positioned, and there is no combined center of gravity between the δ 検 beam 12 and the machining spindle 丨 5 in the existing processing machine 1. Since the machining spindle 15 is moved to the left and right at different positions on the beam 12, after the beam 12 is raised or lowered, the beam 12 is inclined to one side. In addition, after the diaphragm 92 is set at the predetermined height, the rod 44 is reversely raised until the load nut 442 touches the inductor 45, so that the driving of the power source 41 can be stopped, and the beam is completed. 92 positioning action; this does solve the problem that the beam 12 of the existing guard machine i will tilt to one side after moving along the axial direction L. However, the above is only the preferred embodiment of the present invention, and is not limited thereto; t is the scope of implementation of the present invention, that is, the simple scope of the patent scope and the description of the invention in the present invention.
