Abstract
The utility model provides a tool for machining a taper hole of a tractor shaft. The tool comprises a main shaft connection part and a central frame. A supporting bearing is arranged on the inner side of the central frame, and the outer ring of the supporting bearing is fixed to the inner side of the central frame. The tool for machining the taper hole of the tractor shaft guarantees normal machining, effectively prevents the surface of a bearing retainer in the middle of the tractor shaft from being damaged, improves the rate of finished products and increases the economic benefit.
Description
Technical field
The utility model relates to a kind of frock of processing the machine shaft taper hole, belongs to the mechanical device field.
Background technology
In the process of production machine shaft, need to be at a taper hole of front end processing of axle.During conventional production, at the bearing gear in the rear end of axle and stage casing, put and be respectively arranged with chuck and centre frame, be used for axle is fixed.Because the taper hole diameter of processing is less, roughness is had relatively high expectations, and cutting speed that must be higher just can reach effect preferably with higher lathe rotating speed (approximately 1000 rev/mins).But higher cutting speed can be brought very high friction at the bearing gear place, stage casing of centre frame supporting, high friction raises bearing gear place, stage casing temperature, make stage casing bearing gear size become large, cause centre frame and stage casing bearing gear gap smaller, HTHP makes bearing gear surface, stage casing produce damage, cause scrapping of part, reduced yield rate.
The utility model content
The technical problems to be solved in the utility model is to overcome existing defect, and a kind of frock of processing the machine shaft taper hole is provided, and prevents that the bearing gear surface, stage casing of machine shaft is impaired, improves yield rate.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of frock of processing the machine shaft taper hole, comprise main shaft connector and centre frame, and the centre frame inboard is provided with block bearing, and the outer ring of block bearing is fixed on the centre frame inboard.
Further, the block bearing both sides are equipped with dust cover.
Further, be provided with adjusting nut on the main shaft connector.
A kind of frock of processing the machine shaft taper hole of the utility model, when guaranteeing normal process, effectively prevented that the bearing gear surface, stage casing of machine shaft is impaired, improved yield rate, increased economic benefit.
The accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms the part of specification, with embodiment mono-of the present utility model, is used from explanation the utility model, does not form restriction of the present utility model.In the accompanying drawings:
Fig. 1 is a kind of structural representation of processing the frock of machine shaft taper hole of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of frock of processing the machine shaft taper hole, comprise main shaft connector 1 and centre frame 2, centre frame 2 inboards are provided with block bearing 3, the outer ring of block bearing 3 is fixed on centre frame 2 inboards, the stage casing bearing gear of axle 4 to be processed is through the inner ring of block bearing 3, and the rear end bearing gear is inserted in main shaft connector 1, fixing with adjusting nut 5.
The block bearing both sides are equipped with dust cover, prevent that iron filings and dust from entering bearing inside, keep the bearing cleaning inside; Be provided with adjusting nut on the main shaft connector, fixedly the axle to be processed of different size.
A kind of frock of processing the machine shaft taper hole of the utility model, by the friction between axle and centre frame, be converted into the ball friction of block bearing inside, effectively makes the axle surface can not produce damage.
A kind of frock of processing the machine shaft taper hole of the utility model, when guaranteeing normal process, effectively prevented that the bearing gear surface, stage casing of machine shaft is impaired, improved yield rate, increased economic benefit.
Finally it should be noted that: the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment, the utility model is had been described in detail, for a person skilled in the art, its technical scheme that still can put down in writing aforementioned each embodiment is modified, or part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
