Abstract
The invention discloses a rotary oil distributing device special for an internal grinding machine. The rotary oil distributing device special for the internal grinding machine comprises a main shaft and an oil cylinder. The oil cylinder is arranged at the front end inside the main shaft, four hydraulic oil channels are formed in the main shaft, one end of each hydraulic oil channel is connected with the oil cylinder, the other end of the corresponding hydraulic oil cylinder is connected with a hydraulic oil channel in a rotary inner ring, the rotary inner ring is fixedly connected with the main shaft, the hydraulic oil channel of the rotary inner ring is communicated with an oil inlet in the rotary inner ring, the rotary inner ring is fixed inside an oil distributing outer ring through a bearing, an oil filling ring is arranged on the oil distributing outer ring, the oil filling ring corresponds to the oil inlet in the rotary inner ring, and the oil filling ring is communicated with a hydraulic pipe connector. The rotary oil distributing device special for the internal grinding machine has the advantages that the problems that in the prior art, a pull rod is thin and long, deflection is generated easily and precision is influenced are solved thoroughly by chaining the structure of the pull rod of a chuck, the rotary oil distributing device is simple in structure and reduces cost, and a large space is available in the main shaft to allow a detecting device to be mounted.
Description
Technical field
The present invention 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 guaranteeing 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.
Summary of the invention
In order to solve the problems of the technologies described above, the object of this invention is to provide a kind of internal grinder Special rotary distributing device, the present invention breaks through tradition rotation and joins oily mode, thoroughly from structure, carries out technological improvement.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.
Described main shaft is fixed on main spindle box by mainshaft rear bearing, main spindle front bearing, inner spacing collar, outer separator, front gland, rear pressing cover and locking nut.
Advantage of the present invention is: 1. by the change to chuck Tiebar structure, thoroughly solved in prior art pull bar elongated, easily produced amount of deflection, affected the problem of precision; 2. rotation distributing device is simple in structure, has reduced cost; 3. in main shaft, there is larger space that checkout gear is set.
Accompanying drawing explanation
Fig. 1 is 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, 5 for joining oily outer ring, and 6 is hydraulic fitting, and 7 is belt wheel, and 8 is main shaft, 9 is locking nut, and 10 is rear pressing cover, and 11 is mainshaft rear bearing, and 12 is outer separator, 13 is inner spacing collar, and 14 is main spindle front bearing, and 15 is front gland, and 16 is oil cylinder cover, 17 is oil cylinder pull bar, and 18 is hydraulic oil channel, and 19 is fuel feed hole, and 20 is oiling ring, 21 is checkout gear installing hole, and 30 is oil cylinder, 50 oil cylinders that are existing structure, and 51 is pull bar.
The specific embodiment
Below in conjunction with accompanying drawing, illustrate the present invention, 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 invention 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.
