Abstract
The utility model discloses a rotating oil distribution device special for an internal grinding machine. The rotating oil distribution device comprises a spindle and an oil cylinder. The oil cylinder is arranged at the front end of the inside of the spindle, the spindle is provided with hydraulic oil channels, and the number of the hydraulic oil channels is four. One end of each hydraulic oil channel is connected with the oil cylinder, and the other end of each hydraulic oil channel is communicated with one hydraulic oil channel in a rotating inner ring. The rotating inner ring is fixedly connected with the spindle. The hydraulic oil channel of the rotating inner ring is communicated with an oil inlet hole formed in the rotating inner ring, the rotating inner ring is fixedly arranged inside an oil distribution outer ring through a bearing, and the oil distribution outer ring is provided with an oiling ring which corresponds to the oil inlet hole in the rotating inner ring. The oil distribution ring is communicated with a hydraulic pipe joint. The rotating oil distribution device special for the internal grinding machine has the advantages that the chuck pull rod structure is changed, so that the problems that a pull rod is long and thin, deflection can happen easily and precision can be affected in the prior art are thoroughly solved; the rotating oil distribution device is simple in structure and lowers cost; large space can be achieved in the spindle so as to be provided with a detection device.
Description
Technical field
The utility model relates to a kind of rotation distributing device, is a kind of rotation distributing device driving for internal grinder oild chuck specifically.
Background technology
Existing rotation distributing device structure as shown in Figure 2, adopts oil cylinder 50 driven chuck to unclamp and clamped by pull bar 51.Oil cylinder 50 is arranged on the rear end of main shaft, distant with the chuck of front end, and the piston of oil cylinder is driven chuck to unclamp and clamped by pull bar 51.There is following problem in this mechanism: the one, and pull bar is elongated, easily produce amount of deflection, the precision of pull bar is difficult for ensureing and then affecting the transmission accuracy of pull bar, the 2nd, rotary oil cylinder buying expenses is higher, increase use cost, the 3rd, in the case of modern times processing is more and more higher to the requirement of precision, often need to arrange the device that machining accuracy is detected, and existing structure is owing to adopting Tiebar structure, checkout gear cannot be set.
Utility model content
In order to solve the problems of the technologies described above, the purpose of this utility model is to provide a kind of internal grinder Special rotary distributing device, and the utility model is broken through tradition rotation and joined oily mode, thoroughly carries out technological improvement from structure.Concrete technical scheme is as follows:
A kind of internal grinder Special rotary distributing device, comprise main shaft, oil cylinder, described oil cylinder is arranged on the front end of main shaft inside, on described main shaft, hydraulic oil channel is set, described hydraulic oil channel is four, one end of described hydraulic oil channel is connected with oil cylinder respectively, and one end is communicated with the hydraulic oil channel on temperature of inner ring during rotation in addition; Described temperature of inner ring during rotation is fixedly connected with main shaft, and the hydraulic oil channel of described temperature of inner ring during rotation is communicated with the fuel feed hole being arranged on temperature of inner ring during rotation; Described temperature of inner ring during rotation is fixed on and is joined in oily outer ring by bearing, described in join oily outer ring oiling ring be set, described oiling ring is corresponding with the fuel feed hole on temperature of inner ring during rotation; Described distribution oil ring is communicated with hydraulic fitting.
Checkout gear installing hole is set in described main shaft.

Detailed description of the invention
Illustrate the utility model below in conjunction with accompanying drawing, as shown in Figure 1, comprise main shaft 8, oil cylinder 30, described oil cylinder 30 is arranged on the front end of main shaft 8 inside, on described main shaft 8, hydraulic oil channel 18 is set, and described hydraulic oil channel 18 is four, as Fig. 1, upper and lower two, dotted line are two of left and right, and one end of described hydraulic oil channel 18 is connected with oil cylinder 30 respectively, and one end is communicated with the hydraulic oil channel 18 on temperature of inner ring during rotation 4 in addition; Described temperature of inner ring during rotation 4 is fixedly connected with main shaft 8, and the hydraulic oil channel 18 of described temperature of inner ring during rotation 4 is communicated with the fuel feed hole 19 being arranged on temperature of inner ring during rotation; Described temperature of inner ring during rotation 4 is fixed on and is joined in oily outer ring 5 by bearing 2, described in join oily outer ring 5 oiling ring 20 be set, described oiling ring 20 is corresponding with the fuel feed hole 19 on temperature of inner ring during rotation 4; Described distribution oil ring 20 is communicated with hydraulic fitting 6.
The interior checkout gear installing hole 21 that arranges of described main shaft 8.
Described main shaft 8 is fixed on main spindle box by mainshaft rear bearing 11, main spindle front bearing 14, inner spacing collar 13, outer separator 12, front gland 15, rear pressing cover 10 and locking nut 9.
Principle of the present utility model is: join oily outer ring 5 and fix, temperature of inner ring during rotation 4 rotates with main shaft 8; Hydraulic oil enters oiling ring 20 by hydraulic fitting 6, the fuel feed hole 19 of temperature of inner ring during rotation 4 is all the time in oiling ring 20, and therefore, hydraulic oil enters hydraulic oil channel 18 by fuel feed hole 19, then be connected with the oil filler point of oil cylinder 30, thus the motion of control oil cylinder pull bar 17; And then by the motion of oil cylinder pull bar 17, control unclamping and clamping of chuck.
