Abstract
A telescoping mechanism of a numerical control car wheel lathe spindle comprises a spindle, a sleeve and a hydraulic motor, wherein the spindle is inserted into the sleeve; the inner end of the spindle is connected with a coupler through a connecting flange; the other end of the coupler is fixedly connected with a nut; a screw is sheathed in the nut to be connected with the nut; the other end of the screw is fixed with an output shaft of the hydraulic motor; a guide sleeve is arranged outside the screw; and under the action of the screw and the nut, the coupler is driven by a feather key to move in a guide sleeve hole. The hydraulic motor with low speed and high pulling torque is adopted by the telescoping mechanism to drive the screw to rotate in the nut; the coupler is driven by the feather key to move in the guide sleeve hole; the coupler is connected with the spindle through the connecting flange, so that the spindle can move stably in the sleeve; and the hydraulic motor has a good overload protection function; the screw has a reliable self-locking function. Therefore, the mechanism operates stably, is safe to use and can ensure that wheel pairs with different axial lengths can all be located correctly.
Description
Technical field
The utility model relates to a kind of cnc wheel lathe main shaft telescoping mechanism.
Background technology
At present vehicle wheel adopts turbine, scroll bar mechanical structure mostly to the main shaft retractor device of cnc wheel lathe, and driven by motor turbine, scroll bar, turbine, scroll bar drive screw mandrel again and come stretching of drive shaft and contract.The shortcoming of this structure is that fluctuation of service, accuracy are lower.
Summary of the invention
The purpose of this utility model just provides and a kind ofly operates steadily, cnc wheel lathe main shaft telescoping mechanism safe in utilization.
Cnc wheel lathe main shaft telescoping mechanism of the present utility model, comprise main shaft, sleeve, hydraulic electric motor, main shaft is inserted in the sleeve, the inner of main shaft links to each other with shaft coupling by connecting flange, and the affixed nut of the other end of shaft coupling, screw mandrel are enclosed within the nut and join with nut, the other end of screw mandrel and hydraulic electric motor output shaft are fixed, screw mandrel is provided with fairlead outward, and shaft coupling is provided with feather key, and shaft coupling is moving in the guiding trepanning by the feather key drive under screw mandrel and the nut effect.
Cnc wheel lathe main shaft telescoping mechanism of the present utility model, its main shaft is flexible to be to adopt the low-speed big hydraulic electric motor to drive screw mandrel to rotate in nut, driving shaft coupling by feather key moves in the guiding trepanning, shaft coupling is linked together by connecting flange and main shaft, makes main shaft can do steadily to move in sleeve.Hydraulic electric motor has good overload protection function, and screw mandrel has reliable self-locking action, thus this mechanism operate steadily, safe in utilization, can guarantee can obtain correct positioning to equal to the wheel of different axial lengths.
Description of drawings
Fig. 1 is the utility model structural representation.
