Specific implementation mode

As shown in Fig. 1 ~ 5, a kind of stonecutter main shaft adjustment structure, including engine base moving up and down 100, the engine base 100 lower parts have to install the support shaft 200 of saw blade 600 along horizontally disposed, are provided with positioned at support shaft both ends on the engine base And the coaxially connected main shaft 300 with support shaft, both sides are provided with and can be led with respect to the motor 400 that engine base horizontally slips above engine base One end is connect axis with respective side motor drive outwardly；Engine base lower part both sides are provided with can be with respect to the spindle drum that engine base horizontally slips 500, the motor 400 of both sides and the spindle drum 500 of both sides can synchronize be moved to the left or right；It is moved to the left or to the right by spindle drum It is dynamic, can realize the adjusting to supporting shaft position, to realize that saw blade position is adjusted, realize cut stone to knife and correcting function, Simultaneously when spindle drum move, the motor of main axis also synchronizes movement in the same direction on driving spindle seat, ensure motor and main shaft it Between steady and continuous drive connection.

In the present embodiment, 100 lower part both sides of engine base are separately installed with the master for driving respective side spindle drum 500 to move Axis Shift cylinder 310,100 top both sides of engine base are respectively arranged with the motor passive oil for driving respective side motor 400 to move Cylinder 410；100 lower part both sides of engine base are additionally provided with by the flexible motor actuating cylinder 420 of the driving of main axle moving oil cylinder 310, described The oil inlet and outlet of the passive oil cylinder of the oil inlet and outlet of motor actuating cylinder 420 and the motor of respective side 410 is connected, the main shaft of homonymy The telescopic rod of Shift cylinder 310 and motor actuating cylinder 420 is connected to same on the connecting plate 510 of 500 side of spindle drum； When main axle moving cylinder efficient, motor actuating cylinder is driven to do identical action, motor actuating cylinder interior oil by connecting plate Buckling forces the passive oil cylinder of motor to make action identical with motor actuating cylinder, and then realizes that motor is synchronous with main shaft and move It is dynamic；The synchronization-moving structure of the realization is relatively simple, stable and reliable in work.
