Technical field
The utility model relates to a kind of drive unit that is applied to metal cutting processing, especially can directly apply to the technologies such as the surface of revolution, plane, forming surface of the various metal materials of Milling Process.
Background technology
At present, the structure of known milling drive unit is to be in series by motor, gearbox and mill principal axis assembly.At first, the output shaft of motor has rotatablely moving of constant speed, and the motive power of output milling passes to gearbox.Then, according to the cutting speed requirement of milling process, the rotary speed of motor output shaft passes to mill principal axis after the gearbox speed change.At last, drive milling cutter by milling spindle and be rotated motion, and then finish the requirement of milling workpiece.But such drive unit has big, the Heavy Weight of volume, and inertia is big, and shortcoming such as the system architecture spatial degrees of freedom is little.Especially the transmission mechanism of gearbox has adopted gear-driven mode, can't realize stepless speed change function.In addition, corresponding Machinery Control System is also complicated, and inconvenient operation is difficult for realizing automation and overload protection etc.
Summary of the invention
The deficiency of aspects such as, Heavy Weight big for the complex structure that overcomes traditional electrical machinery device, volume and output rigidity are little, the utility model provide a kind of and have had simple in structurely, and volume is little, in light weight; The transmission moment of torsion is big; The motion uniform and stable; Can in very big velocity interval, realize the milling drive unit of function of stepless speed regulation easily.
The technical scheme that adopts is:
A kind of milling drive unit of the present utility model, comprise hydraulic motor system and mill principal axis, described hydraulic motor system comprises hydraulic motor, adjusts valve, overflow valve, hydraulic pump, described hydraulic pump is a variable pump, and this variable pump and flow valve are formed volume-flow control circuit; It is characterized in that described cutter spindle by coupling sleeve directly and hydraulic motor output shaft link.
On above-mentioned oil return line, increase a sequence valve;
The utility model compared with prior art has the following advantages:
1, because inline prime mover scheme is adopted in the rotation of mill principal axis, and promptly hydraulic motor output shaft is exactly a main shaft, transmission link in the middle of not having can make mill principal axis not be subjected to the transmission moment of flexure.Like this, can make whole mill principal axis modular construction simple, compact, have a very strong practicality.
2, power weight ratio is big: the power weight ratio of hydraulic motor system is 10 times of electromechanical compo;
3, moment of torsion-ratio of inertias is big: the moment of torsion-ratio of inertias of swinging hydraulic motor is 10～20 times with the capacity motor;
4, easy to operate, laborsaving, the free degree in system architecture space is big, can realize the stepless speed regulation in the very big velocity interval;
5, power output and transmission moment of torsion are big, transmit the motion uniform and stable, are easy to realize overload protection;
6, hydraulic control component standardization and generalization degree height help shortening design, manufacturing cycle and the reduction manufacturing cost of complete machine, have very strong practicality.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a hydraulic motor system schematic diagram of the present utility model.
Fig. 2 is inline prime mover milling spindle installation diagram of the present utility model.
The specific embodiment
A kind of milling drive unit comprises hydraulic motor system and mill principal axis 1; Hydraulic motor system comprises hydraulic motor 2, fuel tank 3, filter 4, motor 5, hydraulic pump 6, flow speed control valve 7, oil pressure gauge 8, overflow valve 9, and wherein, hydraulic pump 6 adopts variable pump, to reduce heating, saves energy; Hydraulic pump 6 is formed volume speed-modulating loop with flow valve, to satisfy speed load characteristic and demanded power output; Hydraulic pump 6 is extracted hydraulic oil out under the driving of motor 5 from fuel tank 3, enter in the flow speed control valve 7, and then, after the speed governing of flow speed control valve 7, hydraulic oil enters into hydraulic motor 2, drives the milling cutter rotation, after in the overflow valve 9 inflow fuel tanks 3.For strengthening the speed rigidity, on oil return line, increase a sequence valve 13, play the back pressure effect.Hydraulic motor 2 is by being bolted on the main shaft casing 10, and the output shaft of hydraulic motor 2 directly extend into and connects in the axle sleeve 11, connects axle sleeve 11 and is connected with mill principal axis 1 by flat key 12, thereby transmit hot square and rotatablely move.The front end of mill principal axis 1 supports by a bearing 14, and its rear end is supported by a bearing 15.The structure that the axial location of forward and backward bearing adopts main shaft to protract is adjusted the gap of bearing 14,15 by rotating nut 16 and rotation nut 17.The front end of mill principal axis 1 has bearing (ball) cover 18, and this end cap 18 is by being bolted on the main shaft casing 10, and the end cap projection withstands the outer ring of bearing 14.Rear end cap 20 is fixed in the rear end of main shaft casing 10 by bolt 21, and the leading section of mill principal axis 1 has sealing felt collar 19, enters in the main shaft casing 10 to prevent the dust foreign material.Mill principal axis 1 is a hollow structure, and milling cutter pull bar 22 passes mill principal axis 1 inner chamber and milling handle links.
In addition, in order to strengthen mill principal axis 1 self rigidity, improve the resistance to shock of mill principal axis 1, the diameter dimension that shortens the front end amount of overhanging of mill principal axis 1 as far as possible and suitably increase mill principal axis 1.When condition is permitted, suitably increase the diameter dimension of mill principal axis 1, can reduce the amount of deflection that mill principal axis 1 produces under the load effect, improve the rigidity of axis system, improve the resistance to shock of spindle unit.
