Specific embodiment
The principle and embodiment that the invention will now be described in detail with reference to the accompanying drawings.
As shown in Figure 1, double-end polishing machine main shaft of the invention is the main shaft of high-power, large torque steel ball bearing.This pair
Head polishing machine main shaft is mainly by rotor assembly 27, body assembly 17, front axle bearing assembly 10, rear axle bearing assembly 16 and end-cap assembly
26 compositions.
The fixed polishing wheel shank 22 in 27 both ends of rotor assembly and polishing wheel (not shown), in the present embodiment, rotor
Component uses ER32 interface, standardize the size for polishing wheel shank 22 can, easy to use, at low cost, interchangeability it is high and repeat it is fixed
Position precision is high.Rotor assembly 27 specifically includes: central spindle 4, mouse cage 15, collet chuck 23 and nut 20.Mouse cage 15 is fixed on 4 outer wall of central spindle
On, it is interference fitted with central spindle 4, the both ends of central spindle 4 are equipped with inner hole, and for installing polishing wheel shank 22, polishing wheel shank 22 is put in
There are certain distances for end and the bottom of inner hole, and polishing wheel shank 2 is hollow structure, and collet chuck 23 is stuck in inner hole inner wall and polishing wheel
Between 22 outer wall of handle, 20 sets of the nut outsides in central spindle 4 and polishing wheel shank 22 are locked, to carry out to polishing wheel shank 22
It is fixed, from the figure we can see that, the inner wall of inner hole is the conical surface that internal diameter is gradually reduced, and 23 outer wall shape of collet chuck matches with it
It closes.Wherein inner hole, collet chuck 23 and nut 20 use ER32 interface, versatile and the case where guarantee precision for polishing tool dismounting
Under provide a great convenience.
End-cap assembly includes two end caps, 12, four end cap pressing plates and two pressure rotary oil seals 21, two end caps 12
It covers outside rotor assembly 27, end cap pressing plate 2,13 is arranged in two sides of each end cap 12, and pressure rotary oil seal 21 is by two
End cap pressing plate 2,13 is sealed between end cap and rotor assembly.Wherein the side of end cap 12 namely its periphery is equipped with and can make
The water inlet interface 28 of its central water outlet, the i.e. inlet pipeline of end cap 12 are radially arranged, water outlet and 28 phase of water inlet interface
To setting, as shown in Fig. 2, injecting certain pressure to polishing wheel shank 22 by the water inlet interface 28 when main shaft polishes or grinds
Coolant liquid or polishing fluid, coolant liquid or polishing fluid polishing wheel end face is entered everywhere by polishing wheel shank 22, main shaft is made to work
When polishing wheel and product between can cool down and lubricate in real time, to reach ultraprecision grinding and polishing.2,13 points of end cap pressing plate
Not Tong Guo bolt pressure rotary oil seal 21 is locked at 12 center of end cap, since to be made into separation removable for end cap pressing plate 2,13, make
The replacement of pressure rotary oil seal 21 becomes simple, time saving and energy saving.Pressure rotary oil seal 21 with make here main shaft in high revolving speed (1
Ten thousand revs/min) when water inlet interface 28 enter coolant liquid or polishing fluid will not enter main shaft in, be directly entered the end of polishing wheel
Face.
Rear axle bearing assembly 16 specifically includes: rear bearing block 6, bearing, bearing prestretching sliding sleeve 9 and O-ring seal.Rear bearing
Seat 6 band flange and boss, positioned in main shaft it is more convenient, 9 one end of bearing prestretching sliding sleeve be set to body assembly 17 in, the other end with
6 end face of rear bearing block and inner circle clearance fit, specifically, bearing prestretching sliding sleeve 9 and 6 end face of rear bearing block are wide arc gap cooperation,
Fit clearance can eliminate the error in processing and assembling process in 1mm or so as far as possible.9 outer circle of bearing prestretching sliding sleeve and rear bearing
Seat 6 inner holes using small―gap suture cooperate, fit clearance is about 0.001-0.004mm, enable bearing prestretching sliding sleeve 9 slide and have compared with
High positioning accuracy, 9 outer diameter of bearing prestretching sliding sleeve are bolted rear bearing block 6 and directly bear against on the end face of bearing, bearing
Firmly beforehand means be pre- pull-type preload, improve the service precision of bearing.Sealing ring is O-ring seal, is arranged in rear bearing block
It is sealed between rotor assembly.
16 end face outside of rear axle bearing assembly also sets up bearing plate component, bearing plate component include bearing plate 18,
Bearing nut 3 and pressing plate copper sheathing 19 are equipped with closed type chamber between bearing plate and pressing plate copper sheathing.In spindle operation, gas
Enter from air inlet pipe 24, air pressure enters this closed type chamber, then the gear hobbing by 19 outer circle of pressing plate copper sheathing by the gas circuit on ontology
Gap is issued to main shaft both ends, labyrinth type air cavity is formed with bearing nut 3, as shown in Figure 3, Figure 4, to prevent outside main shaft
Dust, coolant liquid or polishing fluid, which enter, burns out motor inside main shaft.
Front axle bearing assembly mainly includes front-end bearing pedestal 5, bearing, front-end bearing pedestal cover board 1 and o type sealing ring etc..Fore bearing
Seat is also with flange and boss, good positioning effect.Cover board, which is arranged in body assembly, is located at front-end bearing pedestal inner side end, the sealing of o type
Circle setting is sealed between front-end bearing pedestal and rotor assembly.Front-end bearing pedestal 5 uses separation design, and the processing is simple, exchanges
Property it is high.
Body assembly mainly includes ontology 11, coil 14, warter connection 25 etc..Coil 14 is arranged in ontology 11 and turns
The mouse cage of sub-component interacts, and as shown in Figure 5, Figure 6, labyrinth type circulation waterway is equipped in ontology, warter connection 25 is connected to
The water route.Water route is made of a plurality of straight tube cooling water channel for being arranged in ontology and being parallel to central spindle, adjacent straight tube cooling water
Road is end to end, to form mazy cooling water channel, is cooled down at work for main shaft, it is ensured that the environment temperature of its work
Degree.
Ontology 11 is the core with external connection of entire main shaft, while being also the assembly of entire spindle core accessory
Main body.Ontology 11 assembles threaded hole by both ends of the surface and links together with rear axle bearing assembly 16, front axle bearing assembly 10.Coil 14 is logical
The coil location hole for crossing 11 side of ontology carries out axial direction and radial positioning.There is labyrinth type cooling circulating water on this main shaft body 11
Road, it is ensured that main shaft is in normal temperature state in the running.
Main shaft of the invention uses steel ball bearing, and assembly is simple.The firmly beforehand means of bearing are pre- pull-type preload, improve axis
The service precision held.Make main shaft that axially there is stronger axial force simultaneously, reaches the function of grinding.And maximum speed of spindle
It can reach 10,000 rpms.The ontology 11 of main shaft uses straight tube cooling water channel, and it is to make entirely that adjacent straight tube ending, which communicates,
The heat that main shaft generates at work in time take away by cooled recirculated water.Ensure that main shaft is in normal temperature state in the running, can make
It runs without interruption within motor 24 hours.Mouse cage in central spindle 4 uses inserted mouse cage, and with short production cycle, power of motor, torque are more
Greatly.It is big small below before central spindle bearings at both ends position, the quality (weight) of central spindle is reduced in the case where guaranteeing lateral force.And
Using novel 14 structure of coil, double-layer concentric winding, two-way in parallel, wye connection, so that main shaft is compared specifically are used
Similar main shaft has higher torque under identical revolving speed.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
