In order to enhance the structural strength of the upright 12, the inner walls of the through slots 1211 are provided with cross-type reinforcing ribs (not shown).

In order to facilitate the removal of the numerical control drilling, tapping and milling integrated processing equipment with the central through hole for water outlet, at least one group of protruding parts 121 are symmetrically arranged on the vertical frame 12, rope penetrating holes for ropes to pass are formed in the protruding parts 121, when the processing equipment is moved, a lifting arm of a forklift is inserted into the bottom of the base 11, the rope penetrating holes in the protruding parts 121 are connected with one ends of the ropes, the other ends of the ropes are fixed on the forklift, and therefore the processing equipment is fixed, the movement of the processing equipment is facilitated, and meanwhile the lifting of the processing center is facilitated.

Referring to fig. 9 and 14, in order to facilitate the installation of the synchronous pulley 142, a bushing 1421 capable of tightly holding a rotating shaft is disposed on an inner wall of the synchronous pulley 142, the bushing 1421 is symmetrically provided with two open slots 1423 along an axial direction thereof, the two open slots 1423 divide the bushing 1421 into two same tightly holding portions, an outer diameter of the bushing 1421 gradually increases from an open end to a sealed end of the open slot 1423, so that an outer wall of the bushing 1421 forms an inclined outer ring surface with an inverted trapezoid cross section, the inner wall of the synchronous pulley 142 is tightly pressed against the outer wall of the bushing 1421, a minimum value of an inner diameter of the synchronous pulley 142 is smaller than a minimum value of the outer diameter of the bushing 1421, a limit block 1422 for preventing the synchronous pulley 142 from coming off is disposed on a side wall of the bushing 1421 at a position far from the open slot 1423, a lock ring sleeve 1424 for tightly pressing the synchronous pulley 142 is detachably disposed on a position of the bushing 142, and two sides of the synchronous pulley 142 are annularly provided with a limit ring 1425 for preventing the synchronous belt 143 from deviating.

When the synchronous pulley 142 is installed, the bushing 1421 is axially sleeved on the rotating shaft of the motor, the limiting table 1422 is on the same side as the motor when in sleeving, the clasping portion is close to the rotating shaft, then the synchronous pulley 142 is sleeved outside the bushing 1421, the inner wall of the synchronous pulley 142 is pressed against the outer wall of the bushing 1421, because the minimum value of the inner diameter of the synchronous pulley 142 is smaller than the minimum value of the outer diameter of the bushing 1421, as shown in fig. 9, that is, the inner diameter of the lower end of the synchronous pulley 142 is smaller than the outer diameter of the lower end of the bushing 1421, after the synchronous pulley 142 is completely sleeved, the clasping portions of the two segments are pressed inwards, so that the bushing 1421 clasps on the rotating shaft of the motor, and because the outer wall of the bushing 1421 forms an inclined outer ring surface with an inverted trapezoid cross section, the inner wall of the synchronous pulley 142 is pressed against the inner wall of the synchronous pulley 142 through the inclined outer ring surface, therefore, the lining 1421 and the synchronous pulley 142 are clamped, and the locking ring sleeve 1424 is installed on the lining 1421, so that the installation of the synchronous pulley 142 is completed.

Based on the above scheme, in actual operation, the first driving device, the second driving device, and the third driving device may also be hydraulic telescopic rods.

Modifications and variations of the present invention are within the scope of the claims and are not limited by the disclosure of the embodiments.
