Description

The vertical machining centre of processing screw pump screw rod profile
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:
Embodiment 1, and shown in Fig. 1-3, the utility model is made up of parts such as the machine tool chief axis 6 of the platen 4 of high precision dividing head 1, screw rotor 2, tailstock 3, vertical machining centre, profile milling cutter 5, vertical machining centre, push rods 7.This platen 4 can be realized moving horizontally on vertical machining centre, and the utility model is on vertical machining centre, to improve, and the structure of this vertical machining centre is a prior art, does not do at this and gives unnecessary details.One end of said platen 4 is dividing head 1 fixedly; The other end is tailstock 3 fixedly, and said tailstock 3 is provided with push rod 7, and an end of said push rod 7 is provided with top 7a; The other end of said push rod 7 is set in the installing hole of tailstock 3; And between the inwall of installing hole and push rod 7, bearing is housed, and an end of screw rotor 2 is installed in the main shaft endoporus of dividing head 1, and the top 7a of the other end and push rod 7 pushes against.Said profile milling cutter 5 is installed in the lower end of machine tool chief axis 6, and said profile milling cutter 5 is above the platen 4 and at tailstock 3 and fixedly between the dividing head 1.Said profile milling cutter 5 is a finger cutter, and has four cutting blades, and these four cutting blades are evenly distributed on the circular cone cutting face.Be the driving screw milling cutter among Fig. 2, be used to process driving screw, Fig. 3 is from the screw rod milling cutter, is used for processing from screw rod.
