Abstract
The utility model relates to a tool for grinding an excircle of a bearing seat. A spindle is tapered, and B3.15 central holes at two ends of the spindle are ground before the spindle is used. The tool is connected with a machine tool by the central holes and an apex, and the apex is arranged on an excircle grinding machine. The taper of the spindle is 0.03mm, and is matched with the taper of an inner hole of the bearing seat. When the tool is in use, the bearing seat is arranged on the spindle, and then a smooth gasket is arranged at one end of the spindle with threads and is fastened by a nut, so that the bearing seat is positioned between the spindle and the gasket. The tool for grinding the excircle of the bearing seat has the advantages of being good in positioning property, is capable of avoiding damage to the inner hole during processing as the contact area between the tool and the inner hole is small, and is convenient for installing and dismounting the bearing seat to be processed, and the like. Simultaneously, the production efficiency is improved and the good practical value is realized.
Description
Technical field
The utility model relates to the compressor end bearing seat cylindrical grinding frock that a kind of endoporus is a blind hole.
Background technology
Bearing block is the critical component of booster, mainly plays the effect of coupling housing and journal bearing, plays important effect when booster is worked, and is therefore very high to the processing request of this part.The endoporus of compressor end bearing seat is a blind hole.Be to guarantee the processing dimension and the form and position tolerance of bearing block, common processing method be after the operation of grinding endoporus, is through among the endoporus with common mandrel, after making endoporus and mandrel contacting fully, part is carried out the grinding of cylindrical and end face on grinding machine.The shortcoming of this processing method mainly contain following some:
The bad assurance of 1 machining accuracy.Adding man-hour, because endoporus is a blind hole, with contacting apart from weak point of mandrel, occurring the deviation of part easily in the process of processing, it is excessive that the part form and position tolerance appears in the result, or the uneven situation of the CHI-pulse and CUN-pulse being irregular of same batch of part.
2 working (machining) efficiencies are low.The gap of endoporus and mandrel is too small, and the time of artificial punching axle is long.After completion of processing, mandrel is difficult for taking out.
3 are unfavorable for the protection to bearing block.Endoporus has been worked into the drawing requirement before the punching axle, and the contact-making surface of endoporus and mandrel is big, and the rotating speed height of grinding machine can cause to a certain extent damage to endoporus.
Summary of the invention
The technical problems to be solved in the utility model is to be the unmanageable problem of compressor end bearing seat cylindrical of blind hole at endoporus, and a kind of bearing block cylindrical grinding frock is provided.
This bearing block cylindrical grinding frock, the centre bore to mandrel two ends B3.15 before using grinds.Frock is connected with top with the machine adopted centre bore, and is top on cylindrical grinder.Mandrel is the tapering mandrel, and tapering is 0.03mm, cooperates with the hole taper of bearing block.Bearing sleeve is contained on the mandrel, puts smooth smooth pad at the threaded end of mandrel, and is fastening with nut, and bearing block is in the middle of mandrel and the pad, and the nut that is screwed on the mandrel is pressed on the bearing block.Bearing block one end has nut fastening, and the other end has mandrel to support the location, adds at cylindrical grinder like this and just can remove original beat problem man-hour, makes the size of bearing block and form and position tolerance reach the drawing requirement.
Compared with prior art, this bearing block cylindrical grinding frock has that polarization is good, and mandrel and inner hole of bearing seat contact-making surface are little, adds not damage endoporus man-hour, the advantages such as bearing block of conveniently install, dismounting is to be processed.Simultaneously, improve production efficiency, had good practical value.
Description of drawings
Fig. 1 is a compressor end bearing holder structure schematic diagram.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail:
Fig. 1 is the bearing block structure schematic diagram.For the difficulty of this workpiece is that the endoporus of this workpiece is a blind hole, the design of drawing is to be benchmark with the endoporus, the excircle dimension that guarantees part is in the margin of tolerance, and the axiality that guarantees cylindrical is 0.015mm, when guaranteeing part end face 9mm and 27.1mm size, guarantee that the perpendicularity of end face and endoporus is 0.02mm.The drawing endoporus is a blind hole, so designing frock and adding necessary strict control in man-hour.
Fig. 2 is a structural representation of the present utility model.This bearing block cylindrical grinding frock is connected with top with the machine adopted centre bore, and is top on cylindrical grinder.Centre bore to mandrel two ends B3.15 grinds earlier before using, and can use after grinding, and the form and position tolerance when making the levelness of frock and lathe and use is guaranteed.
This bearing block cylindrical grinding frock adopts the good mandrel 1 of polarization, and mandrel 1 is the tapering mandrel.Through calculating, the tapering of 0.03mm cooperates with the endoporus of bearing block 4.Because endoporus is blind hole, the contact position of mandrel 1 and bearing block 4 endoporus guarantees over half in the endoporus distance, but mandrel 1 can not be run into the end face in the blind hole.Mandrel 1 is stuck in the middle of the endoporus, and is little with the contact-making surface of endoporus, is not easy to damage endoporus.Bearing block 4 is sleeved on the mandrel 1, bearing block 4 and mandrel 1 taper fit.Add smooth smooth pad 3 at mandrel 1 a threaded end, use nut 2 fastening again, make bearing block 4 be in the centre of mandrel 1 and pad 3.One end of bearing block 4 has nut 2 fastening, and the other end has tapering mandrel 1 to support the location, adds at cylindrical grinder like this and just can remove original beat problem man-hour, makes the size of bearing block 4 and form and position tolerance reach the drawing requirement.
