The cutting head of formula stonecutter will generally be arranged to rotatably.The driving rotational structure of existing cutting head mainly includes lifting
Slide plate, the oil cylinder located at lifter slide top surface, the side of the oil cylinder are installed with rack fixing seat and rack, the piston of the oil cylinder
Bar is fixedly connected with one end of a connecting plate, and the other end of the connecting plate is fixedly connected with one end of rack, the gear and rotation
Turn support coaxially connected.The oil cylinder of above-mentioned driving rotating mechanism and the power transmission of rack rely primarily on connecting plate and transmitted,
The piston rod of oil cylinder and the stress of rack be not conllinear, so that the unbalance stress of rack, rack is easily damaged.
Utility model content
The utility model provides a kind of bridge type stone cutting machine hydraulic-driven rotational structure, and its main purpose is to overcome existing
With the presence of the above mentioned problem of technology.
The utility model, which is adopted the following technical scheme that, to be achieved：
A kind of bridge type stone cutting machine hydraulic-driven rotational structure, including lifter slide, the top surface of the lifter slide are provided with oil cylinder,
The front side of the oil cylinder is provided with the rack being connected with its piston rod, and the side of the rack is provided with the gear engaged, the lifting
The top surface of slide plate, which is provided with, is used for limiting gear rotational angle position-limit mechanism between 0-90 °, and the bottom of the gear is provided with bearing
Bearing is provided with box, the bearing box, the lower section of the lifter slide is provided with runing rest, and the bearing inner sleeve is provided through gear
With the axis of lifter slide, the top of the axis is lock onto on gear by round nut, and bottom and the runing rest of the axis connect
Connect.
Further, the circular arc distance that the periphery of the gear is provided between two limited mouths, two limited mouth is outside gear
The a quarter in week, the position-limit mechanism includes the locating oil cylinder that is obliquely installed, the piston rod of the locating oil cylinder be provided with it is spacing
The limited block that mouth is adapted.
From above-mentioned to description of the present utility model, compared to the prior art, the utility model has the following advantages that：This
Utility model structure is novel, ingenious in design, and the front side of the oil cylinder is provided with the rack being connected with its piston rod, so passes through control
The piston rod of oil cylinder it is flexible can the movement with carry-over bar so that the rotation with moving gear, rack in moving process all the time
With the piston rod of oil cylinder on the same line, this assures rack in moving process uniform force, the use longevity of rack
Life is longer.
