Utility model content
The utility model object is to provide the gear rolling machine that a kind of Dual-Servo Motor drives, the synchromesh gear tooth bar existed to solve prior art can wear and tear in During Process of Long-term Operation, the relative positional accuracy of upper and lower gear rolling knife can be affected for a long time, affect processing work quality; And hydraulic-driven slide unit must be furnished with hydraulic system that is high-power, large discharge, it cover an area of, consume energy large, noise greatly and the problem of not energy-conserving and environment-protective.
The technical solution of the utility model is: the gear rolling machine that a kind of Dual-Servo Motor drives, and comprises upper cover, base, upper slide unit, lower slide unit; Top cap is connected on the upper end of base, between upper cover and front of chassis, be provided with cavity, this cavity top and bottom Central Symmetry, slip, flatly install slide unit and lower slide unit; The front end of upper cover extends forward and is provided with tailstock, in the front of upper cover, guidance panel is housed; Described upper slide unit and lower slide unit are in transmission connection with upper drive unit and lower drive unit respectively, it is characterized in that, described upper drive unit is identical with lower drive unit, comprise servomotor and ball-screw, the output shaft of servomotor is coaxially connected with screw mandrel one end of ball-screw, the screw mandrel of the ball-screw of upper and lower drive unit is rotatably supported on upper cover and base respectively, and corresponding with upper slide unit and lower slide unit, and the nut of upper and lower drive unit is connected with upper slide unit and lower slide unit respectively; Described upper cover and base install a grating scale respectively, and the read head of two grating scales is connected on upper slide unit and lower slide unit respectively by a read head support.
At least reinforcing is interconnected with two pieces of connecting plates between before described upper cover and base.
The utility model has the advantages that: adopt servo-drive system and grating scale to detect, drive two ball-screws to ensure the synchronism of two slide units respectively, structure is simple, without the need to the gear pair of complex precise; Two slide units can distinguish action, not only can ensure the precise synchronism of two slide units, and can revise the error between gear rolling knife and fixture, therefore can reduce the error of Workpiece Machining Accuracy.The cancellation of Hydraulic Station simultaneously, can realize saving the objects such as space, economize energy, minimizing noise.Automatically controlled machine by guidance panel, the labour intensity of workman reduces, easy left-hand seat easy to learn, and the spline precision of processing is very high, and processing cost is very low, and applicable factory is extensive, production in enormous quantities.
