Abstract
The invention relates to a gear cutting machine, in particular to a numerical control gear hobbing machine hob spindle mechanism. An oil mist lubricating port, an operation gas circuit port and an operation oil circuit port are arranged on the mechanism. A pull claw, a pull rod, a mold spring and a nut are all arranged in a spindle. An angular contact bearing is arranged at a front shaft neck of the spindle, and a double-line cylindrical roller bearing is arranged at a rear shaft neck. An operation oil cylinder at the rear end of the spindle is fixed on a spindle box. The numerical control gear hobbing machine hob spindle mechanism has the advantages that a spindle rear bearing is the double-line cylindrical roller bearing and is good in rigidity; a spindle bearing adopts an oil mist lubrication method which enables the spindle bearing to be fully lubricated so as to increase rotary speed of the spindle; the center of the spindle blows gas and can blow a locating conical hole on the front portion of the spindle cleanly so as to guarantee repeated installing precision of a hob; and the mold spring is used for locking the pull claw, installing is convenient, and cost is low.
Description
Technical field
The present invention relates to a kind of gear cutting machine, especially relate to a kind of hobboing cutter mainshaft mechanism of gear-hobbing machine.
Background technology
Gear-hobbing machine generally uses spiral hobbing cutter to press the generating Machining of Gear at present, and the hobboing cutter Machining of Gear generally all is an interrupted cut, and the suffered impulsive force of hobboing cutter main shaft changes greatly and be rapid; Main shaft rigidity and rotating speed are required than higher; And hobboing cutter mainshaft mechanism common configuration is complicated at present, and cost is high, poor rigidity; Rotating speed is low, can not well satisfy the demand of automation.
Summary of the invention
The object of the invention is exactly the deficiency that will solve above-mentioned existing hobboing cutter main shaft, and a kind of simple in structure, compact and reasonable, easy for installation is provided, and can bear the high rigidity mainshaft mechanism of hobboing cutter of interrupted cut.For this reason, the present invention adopts following technical scheme:
A kind of hobboing cutter mainshaft mechanism that is used for gear-hobbing machine; It is characterized in that: pulling claw is fixed on the pull bar, the adjustable the whole series of nut are stuck on the main shaft endoporus shoulder block at the die springs pressure on the pull bar, die springs front end; Main shaft fixes on the main spindle box through the angular contact bearing of preceding axle journal and the Biserial cylindrical roller bearing of back axle journal, and the piston of rear-end of spindle is connected on the oil cylinder housing.
As the further of such scheme improved and replenish, the present invention also comprises following additional technical feature:
Said main spindle box is provided with the fog lubrication passage, and the Biserial cylindrical roller bearing of the angular contact bearing of preceding axle journal and back axle journal all uses fog lubrication.
Described hobboing cutter mainshaft mechanism is characterized in that: said pull bar and pulling claw are hollow structure, and oil cylinder housing and piston all have passage.
Use the present invention can reach following beneficial effect: because of it uses die springs locking, simple in structure, easy for installation, cost is low; Because of it uses Biserial cylindrical roller bearing, good rigidly can bear the hobboing cutter interrupted cut, can improve hobboing cutter service life.Because of it uses fog lubrication, can improve the speed of mainshaft greatly, promote working (machining) efficiency; Blow because of it uses the alignment of shafts, main shaft prelocalization taper hole is blown off guarantee that hobboing cutter repeats the qualification rate that installation accuracy improves product processing simultaneously greatly, reduced production cost, can realize the automated production requirement.
Description of drawings:
Fig. 1, Fig. 2 are cutaway views of the present invention.
The specific embodiment
Be described in detail below in conjunction with the accompanying drawing specific embodiments of the invention.
The fog lubrication interface is arranged, operation air-path interface and operation oil circuit interface in this mechanism.
Shown in Fig. 1-2, the present invention includes: pulling claw 10 is fixed on the pull bar 8, nut 9 will be enclosed within the die springs 5 rear ends locking on the pull bar 8 and can adjust spring pressure, die springs 5 front ends are stuck on the main shaft 1 endoporus shoulder block; Main shaft 1 is fixed on the main spindle box 4 through the angular contact bearing 2 of preceding axle journal and the Biserial cylindrical roller bearing 3 of back axle journal, and the piston 7 of main shaft 1 rear end is connected on the oil cylinder housing 6.Have the fog lubrication passage on the main spindle box 4, pull bar 8 and pulling claw 10 are hollow structure, and oil cylinder housing 6 and piston 7 all have passage.
The present invention in use, mist of oil gets into bearing chambers through a plurality of fog lubrication passages of opening on the main spindle box 4, and the angular contact bearing 2 of preceding axle journal and the Biserial cylindrical roller bearing 3 of back axle journal are carried out sufficient lubrication; Shown in Figure 1 is pulling claw 10 tensions, and die springs 5 relies on strain that pull bar 8 is strained to the right, and this moment, piston 7 did not contact with pull bar 8 right sides; Be moved to the left through operation oil circuit control piston 7 and force pull bar 8 to drive nuts 9 to continue compression mould springs 5 to pulling claw shown in Figure 2 10 releasing orientations; This moment, pull bar 8 and pulling claw 10 were the passage formation gas circuit path on hollow structure and oil cylinder housing 6 and the piston 7; Compressed air arrives taper hole place, front-end of spindle location through this gas circuit path, and iron filings etc. blow clean here; After treating to be installed in hobboing cutter on the pulling claw 10, move to right through operation oil circuit control piston 7, the gas circuit path breaks off and stops to blow, and die springs 5 dependence strains are strained pull bar 8 to the right and also finally reached pulling claw 10 tensions shown in Figure 1.
