Description
Technical field
The present invention relates to a kind of rotation distributing device, specifically one is for internal grinder hydraulic pressure
The rotation distributing device of chuck drive.
Background technology
Existing rotation distributing device structure is as in figure 2 it is shown, use oil cylinder 50 to be carried by pull bar 51
Dynamic chuck unclamps and clamps.Oil cylinder 50 is arranged on the rear end of main shaft, with the chuck distance of front end
Farther out, the piston of oil cylinder is driven chuck to unclamp by pull bar 51 and is clamped.This mechanism exists
Problems with: one is that pull bar is elongated, easily produces amount of deflection, the precision of pull bar be difficult to ensure and then
Affecting the transmission accuracy of pull bar, two is that rotary oil cylinder buying expenses is higher, increases use cost,
Three is in the case of modern times processing is more and more higher to the requirement of precision, generally require arrange right
The device of precision measurement and detection, and existing structure is owing to using Tiebar structure, it is impossible to inspection is set
Survey device.
Summary of the invention
In order to solve above-mentioned technical problem, it is an object of the invention to provide a kind of internal grinder special
Rotating distributing device, the present invention breaks through tradition rotation and joins oil mode, thoroughly carries out skill from structure
Art is improved.Concrete technical scheme is as follows:
A kind of internal grinder Special rotary distributing device, including main shaft, oil cylinder, described oil cylinder sets
Put and hydraulic oil channel is set on the front end within main shaft, described main shaft, described hydraulic oil channel
Being four, one end of described hydraulic oil channel is connected with oil cylinder respectively, and other end is interior with rotation
Hydraulic oil channel connection on circle；Described temperature of inner ring during rotation is fixing with main shaft to be connected, in described rotation
The hydraulic oil channel of circle connects with the fuel feed hole being arranged on temperature of inner ring during rotation；Described temperature of inner ring during rotation leads to
Cross bearing be fixed on join oil outer ring in, join oil outer ring fix, temperature of inner ring during rotation rotates with main shaft；
Described oil outer ring of joining arranges oiling ring, and described oiling ring is corresponding with the fuel feed hole on temperature of inner ring during rotation；
Described distribution oil ring connection hydraulic fitting；Hydraulic oil enters hydraulic oil channel by fuel feed hole, so
It is connected with the oil filler point of oil cylinder afterwards, thus controls the motion of oil cylinder pull bar.
Detection device installing hole is set in described main shaft.
Described main shaft passes through mainshaft rear bearing, main spindle front bearing, inner spacing collar, outer separator, front pressure
Lid, rear pressing cover and locking nut are fixed on main spindle box.
The invention have the advantage that 1. by the change to chuck Tiebar structure, thoroughly solve existing
There is pull bar in technology elongated, be easily generated amount of deflection, the problem affecting precision；2. rotate distributing device
Simple in construction, reduces cost；3. in main shaft, there is bigger space to arrange detection device.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of prior art；
In figure, 1 is gland, and 2 is bearing, and 3 is oil sealing, and 4 is temperature of inner ring during rotation, and 5 for joining oil
Outer ring, 6 is hydraulic fitting, and 7 is belt wheel, and 8 is main shaft, and 9 is locking nut, and 10 are
Rear pressing cover, 11 is mainshaft rear bearing, and 12 is outer separator, and 13 is inner spacing collar, before 14 are main shaft
Bearing, 15 is front gland, and 16 is oil cylinder cover, and 17 is oil cylinder pull bar, and 18 is hydraulic oil channel,
19 is fuel feed hole, and 20 is oiling ring, and 21 is detection device installing hole, and 30 is oil cylinder, 50
For the oil cylinder of existing structure, 51 is pull bar.
Detailed description of the invention
Illustrate the present invention below in conjunction with the accompanying drawings, as it is shown in figure 1, include main shaft 8, oil cylinder
30, described oil cylinder 30 is arranged on the front end within main shaft 8, and described main shaft 8 arranges hydraulic pressure
Oil passage 18, described hydraulic oil channel 18 is four, such as Fig. 1, upper and lower two, dotted line be left
Right two, one end of described hydraulic oil channel 18 is connected with oil cylinder 30 respectively, other end with
Hydraulic oil channel 18 on temperature of inner ring during rotation 4 connects；Described temperature of inner ring during rotation 4 is fixed with main shaft 8
Connect, the hydraulic oil channel 18 of described temperature of inner ring during rotation 4 and the oil-feed being arranged on temperature of inner ring during rotation
Hole 19 connects；Described temperature of inner ring during rotation 4 is fixed on by bearing 2 joins in oil outer ring 5, described
Join oil outer ring 5 and oiling ring 20, described oiling ring 20 and the fuel feed hole on temperature of inner ring during rotation 4 are set
19 is corresponding；Described distribution oil ring 20 connects hydraulic fitting 6.
Detection device installing hole 21 is set in described main shaft 8.
Described main shaft 8 is by mainshaft rear bearing 11, main spindle front bearing 14, inner spacing collar 13, outer
Spacer 12, front gland 15, rear pressing cover 10 and locking nut 9 are fixed on main spindle box.
The principle of the present invention is: joining oil outer ring 5 and fix, temperature of inner ring during rotation 4 is with 8 turns of main shaft
Dynamic；Hydraulic oil enters oiling ring 20, the fuel feed hole of temperature of inner ring during rotation 4 by hydraulic fitting 6
19 all the time in oiling ring 20, and therefore, hydraulic oil enters hydraulic oil by fuel feed hole 19 and leads to
Road 18, then the oil filler point with oil cylinder 30 is connected, thus controls the motion of oil cylinder pull bar 17；
And then by the motion of oil cylinder pull bar 17, control unclamping and clamping of chuck.
