Abstract
The utility model discloses a vertical machining centre for machining a screw sectional surface of a screw pump, which comprises a machine tool working platform, a machine tool main shaft and a molding milling cutter, wherein the molding milling cutter is arranged at the lower end of the machine tool main shaft; the machine tool working platform is arranged under the molding milling cutter; a dividing head is fixed at one end of the machine tool working platform, and a tailstock is fixed at the other end of the machine tool working platform; the tailstock is provided with an ejector rod which is sheathed in a mounting hole of the tailstock; and one end of a screw rotor is arranged in a main shaft inner hole of the dividing head, and the other end of the screw rotor tightly leans against the ejector rod. The vertical machining centre is reasonable in design, easy to implement, simple in equipment, low in manufacturing cost, low in cutting force during machining, small in deformation of workpieces, and easy for ensuring dimensional accuracy and form and position tolerance.
Description
Technical field
The utility model relates to a kind of vertical machining centre that is used to process screw pump screw rod profile.
Background technology
Screw pump is dynamical element and an executive component important in the hydraulic system, is widely used in industrial circles such as boats and ships, weaponry, engineering machinery, wind-powered electricity generation, food.The processing of tradition screw pump screw rod profile is generally carried out Milling Process by the method that the bolt special milling machine adopts whirlwind to mill, and need design bigger disc milling cutter man-hour adding with screw milling machine, and complex design costs an arm and a leg.And it is big to adopt the bolt special milling machine to add man-hour cutting force, and workpiece deformation is big, and dimensional accuracy, form and position tolerance cannot say for sure card.
The utility model content
The utility model technical problem to be solved is to provide the vertical machining centre of the processing screw pump screw rod profile that a kind of equipment is simple, cost is low, machining accuracy is high.
The technical scheme of the utility model is following: a kind of vertical machining centre of processing screw pump screw rod profile, comprise platen, machine tool chief axis and profile milling cutter, and said profile milling cutter is installed in the lower end of machine tool chief axis; It is characterized in that: an end of said platen is dividing head fixedly; The other end is tailstock fixedly, and said tailstock is provided with push rod, and said top stem casing is contained in the installing hole of tailstock; One end of screw rotor is installed in the main shaft endoporus of dividing head; The other end and push rod push against, and said profile milling cutter is above the platen and between tailstock and dividing head, and said profile milling cutter is a finger cutter; And have four cutting blades, these four cutting blades are evenly distributed on the circular cone cutting face.
Adopt technique scheme, add man-hour, processing work is contained on the screw rotor; Drive the profile milling cutter rotation during machine tool chief axis rotation, dividing head drives the processing work rotation by corresponding rotating speeds, and meanwhile workbench also axially moves according to certain speed; Realize the cut of screw rod profile; This device does not need special-purpose screw milling machine, and profile milling cutter need not adopt expensive disc milling cutter yet, only needs simple in structure; Low-cost finger cutter, and add man-hour cutting force little, workpiece deformation is little, dimensional accuracy, form and position tolerance are prone to guarantee.
In technique scheme, in order to make the power that pushes against of push rod big, guarantee the precision of processing: the end that pushes against that said push rod and screw rotor push against is provided with top.
In technique scheme: between the inner hole wall of the installing hole of said push rod and tailstock bearing is housed.
In technique scheme in order to guarantee machining accuracy: said dividing head is the precision indexing head.
In technique scheme, said finger cutter is a driving screw milling cutter or from the screw rod milling cutter.When the processing driving screw, use the driving screw milling cutter, when processing, use from the screw rod milling cutter from screw rod.
Beneficial effect: the utility model is reasonable in design, enforcement is easy, equipment is simple, low cost of manufacture, add man-hour cutting force little, workpiece deformation is little, dimensional accuracy, form and position tolerance are prone to guarantee.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the driving screw milling cutter of the utility model;
Fig. 3 be the utility model from the screw rod milling cutter.
The specific embodiment.
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
