Description
Technical field
The utility model is related to numerically-controlled precise cylindrical grinder field, more particularly to a kind of numerically controlled cam shaft cylindrical grinder power
Head precision rotation oil cylinder.
Background technology
Numerically controlled cam shaft cylindrical grinder is that camshaft processes important process, and required precision is high, and clamping force is big, to dynamic
Power head precision and pressure requirements are high, and power head precision rotation oil cylinder is to ensure that the important component for transmitting hydraulic pressure.
Utility model content
Purpose of utility model：The purpose of this utility model is to solve deficiency of the prior art, provides a kind of nothing and oozes
Leakage, no pressure loss, pressure transmission speed is fast, good reliability, and the numerically controlled cam shaft cylindrical grinder power head of service life length is used
Precision rotation oil cylinder.
Technical solution：A kind of numerically controlled cam shaft cylindrical grinder power head precision rotation oil cylinder described in the utility model,
Including oil cylinder bar body, transmission shaft, fore bearing, rear bearing, before rear bearing gland, wherein fore bearing are inlaid in oil cylinder body interior
End, rear bearing is inlaid in oil cylinder body interior rear end, and oil cylinder ontology rear end is sealed by rear bearing gland, the oil cylinder ontology
Between inner wall front and back bearings there are three groups of annular grooves, and fore bearing and three groups are passed through equipped with oil sealing, the transmission shaft in annular groove
Rear bearing is penetrated after oil sealing, and the front end of transmission shaft and fore bearing contact surface is equipped with Front oil seal and realizes front end closing.
Preferably, when the transmission shaft is with rear bearing fit, rear axle brought forward end is equipped with adjusting pad, and rear bearing rear end is equipped with
Rear axle baffle ring.
Preferably, the oil cylinder inner body wall front edge is embedded with preceding baffle ring, back edge is embedded with rear baffle ring.
Advantageous effect：A kind of the utility model revealed numerically controlled cam shaft cylindrical grinder power head precision rotation oil
Cylinder has the advantages that：
Front and back bearings is set to realize the rotation of transmission shaft in rotary oil cylinder, while three oil are set between front and back bearings
Envelope, not only realizes the sealing passed in and out to hydraulic oil, while ensures that hydraulic oil does not channel bit during transmission shaft rotation, in oil cylinder body interior
Adjusting pad is set, and the baffle ring of multiple positions ensures that transmission shaft does not generate axial movement.
Compared with prior art, this rotary oil cylinder structure novel, small, transmission oil pressure pressure is big, using rolling friction
Instead of original sliding friction, service life is long, and non-leakage, and no pressure loss, rotation is flexible, and tracking response is fast, axially position
Simply, convenient disassembly is safeguarded.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of the utility model revealed numerically controlled cam shaft cylindrical grinder power head precision rotation oil
Cylinder, including oil cylinder bar body 1, transmission shaft 2, fore bearing 3, rear bearing 4, rear bearing gland 5.
Particularly, the fore bearing 3 is inlaid in oil cylinder body interior front end, and rear bearing 4 is inlaid in oil cylinder body interior
Rear end, the rear bearing gland, which is mounted on the oil cylinder ontology at rear bearing rear, realizes back-end sealing, while oil cylinder ontology is with after
There are three groups of annular grooves 7 on the contact surface of bearing gland between rear baffle ring 6, the oil cylinder inner body wall front and back bearings,
And equipped with oil sealing 8 in annular groove, the transmission shaft 2, which passes through, penetrates rear bearing 4 after fore bearing 3 and three groups of oil sealings 8, and transmission shaft with
The contact surface front-end and back-end of bearing are respectively equipped with adjusting pad 9 and rear axle baffle ring 10, the transmission shaft 2 and fore bearing contact surface afterwards
Front end be equipped with Front oil seal 11 realize front end closing, and oil cylinder ontology front edge go out equipped with preceding baffle ring 12 realize Front oil seal before
The sealing of end face.
The utility model sets the rotation of front and back bearings realization transmission shaft in rotary oil cylinder, while between front and back bearings
Three oil sealings are set, not only realize the sealing passed in and out to hydraulic oil, while ensure that hydraulic oil does not channel bit during transmission shaft rotation, in oil
Cylinder body interior sets adjusting pad, and the baffle ring of multiple positions ensures that transmission shaft does not generate axial movement.
The above descriptions are merely preferred embodiments of the present invention, and not the utility model is made in any form
Limitation, although the utility model has been disclosed with preferred embodiment as above, be not limited to the utility model, it is any ripe
Professional and technical personnel is known, is not being departed from the range of technical solutions of the utility model, when in the technology using the disclosure above
Hold the equivalent embodiment made a little change or be modified to equivalent variations, as long as being without departing from technical solutions of the utility model
Hold, any simple modification, equivalent change and modification that foundation the technical essence of the utility model makees above example, still
Belong in the range of technical solutions of the utility model.
