Description

Part is saved on a kind of rolling coupling spindle

Technical field：

The present invention relates to a kind of component of machine, part is saved on specifically a kind of rolling coupling spindle.

Background technology：

The important part that coupling spindle is machine driven system is rolled, high, deflection is required for product stress and frictional force Greatly, it is desirable that part strength and precision are high, and complex process degree is also higher；At present, it is generally made using traditional machining Make coupling spindle, take a lot of work there are waste material, product is easy to wear or fracture.

Invention content：

The present invention proposes that a kind of roll saves part on coupling spindle, can be smaller under identical cooperation and positioning accuracy Expense manufactures.

Technical solution：

In order to solve the above technical problems, the present invention provides saves part on a kind of rolling coupling spindle, including cylindrical body, institute It states ontology and is divided into six parts, left end is coupling head, and the connector is cylinder, in the direction milling parallel with central shaft Two planes, and planar thickness range is between 5.9-6.0mm；And it is drilled with through-hole in the plane, and through-hole center line is away from connection The distance of axis left side is 9mm, and error is no more than 0.1mm；It is second step face on the right side of the connector, it is a diameter of 8.25mm, and error must not exceed 0.01mm；The coaxiality error of second step face outer circle and the coupling spindle central shaft is not It obtains more than 0.03mm；The second step right side of face is ring flange, left side edges and corners be equipped with width 0.5mm and x-axis it is at 45 ° Angle；Third step surface, the 4th step surface, the 5th step surface and the 6th step surface are followed successively by the right side of the ring flange；Every portion / escape is machined with, and escape width dimensions are between 1.05-1.15mm；The connection shaft through-hole also has Special positioning requirements, on the basis of the central axis for rolling coupling spindle, through-hole symmetry error is no more than 0.1mm；Through-hole institute Two planes also have positioning requirements, equally on the basis of the central axis for rolling coupling spindle, the symmetry error of two planes Also it is no more than 0.1mm.

Preferably, each chamfering rounding of the described part, no chatter mark burr.

Preferably, the described part material is 20CrMo.

It is same as the prior art or the prior art can be used realized that part is not directed in the invention.

Beneficial effects of the present invention：It provides and saves part on a kind of rolling coupling spindle, flash removed is removed after the completion of finished product, through gas Carburizing and quenching processing, reaches higher hardness, is suitble to mass production, and operation can simplify, and quality control easily waits spies Point, is most generally used at present；Higher hardness can extend the usage time of workpiece, and the long period can also keep workpiece Precision；The part is easy to use, easy to operation, and stability is good, and reliability is high, easy to process, at low cost, high yield rate, soon Speed is combined, dismantles and had both truly has apparent enhancement on connection positioning and clipping double effects, is rich in utility value in industry, raw It produces and easy to process, is easy to produce in batches and promote.

Description of the drawings：

Upon reading the detailed description of non-limiting embodiments with reference to the following drawings, other feature of the invention, Objects and advantages will become more apparent upon.

Fig. 1 is to save part overall structure figure on a kind of rolling coupling spindle of the present invention；

Fig. 2 is to save part coupling head sectional view on a kind of rolling coupling spindle of the present invention.

Figure label：1 it is coupling head, 2 be second step face, 3 be third step surface, 4 be the 4th step surface, 5 is the 5th Step surface, 6 be the 6th step surface, 7 be ring flange, 8 be through-hole.

Specific embodiment：

Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments, is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work Embodiment shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that term " on ", " under ", "front", "rear", "left", "right", " top ", The orientation or position relationship of the instructions such as " bottom ", " interior ", " outer " are based on orientation shown in the drawings or position relationship, merely to just In the description present invention and simplify description rather than instruction or imply signified device or element must have specific orientation, with Specific azimuth configuration and operation, therefore be not considered as limiting the invention.
