Description

A kind of accurate shell type honing head for Horizontal honing machine

Technical field

The utility model relates to hones, and in particular to a kind of accurate shell type honing head for Horizontal honing machine, It can be suitably used for the long accurate honing in any aperture, the hole of the be capable of processing range of Horizontal honing machine.

Background technique

Honing is a kind of method for metal working, forms grinding tool with several oilstones or emery stick, makees rotation and reciprocal in workpiece Movement.Honing can make workpiece reach very high precision and finish.There are two types of modes for honing at present, first is that horizontal honing, horizontal Honing device is simple, and it is fast to change production.Second is that vertical honing, vertical honing speculative investment is big, and it is slow to change production.However, Horizontal honing machine makes It is honing head with successful key.The honing of precision pair mesoporous is carried out using the honing head of original structure, machining accuracy is always Requirement cannot be reached.Referring to Fig. 1, crude oil stone 40 is welded on former oil stone base 30, and former oil stone base is mounted on former honing head body 20, Former honing head body and former feeding cone 10 cooperate.It is following to find that original honing head there is a problem of through analysis and research:

(1) honing stone is welded on oil stone base, and oil stone base is mounted in the rectangular channel in the honing head body of frame structure, is matched Conjunction face is more, and gap is also just more；Honing head body slot is more, poor rigidity, and such structure manufacture difficulty is also big；

(2) oil stone base is to cross taper body by two or three in feed bodies to support, and oilstone deforms in honing process, because And cause the processing request that Honing process precision is unable to satisfy us.

Therefore, it is necessary to develop a kind of novel honing head for being able to satisfy requirement on machining accuracy.

" a kind of Collapsible honing head " disclosed in CN 201264210, the solution is to existing Collapsible honing heads not Can directly process with width be greater than single oilstone groove or notch workpiece the technical issues of.The honing head include shell, Harmomegathus part, the oil stone base on harmomegathus part, the oilstone on oil stone base of the radial harmomegathus of energy on shell, feature Be: the oil stone base is to be sheathed on harmomegathus part and fixed open type lantern ring, along axis on the outer peripheral surface of open type lantern ring To at least one oilstone is set in parallel, the open type lantern ring, oilstone can be with harmomegathus part radial direction harmomegathus.It can be improved labour life Yield and product quality.But it is not directed to the problem of how improving Honing process precision.

Summary of the invention

The purpose of the utility model is to provide a kind of accurate shell type honing heads for Horizontal honing machine, can be used in a variety of The processing of the precision pair in size aperture guarantees Honing process precision.

A kind of accurate shell type honing head for Horizontal honing machine described in the utility model, including taper push rod, inner wall Ontology is covered with the honing that the outside of taper push rod cooperates, is fixed on upper a plurality of oilstone outside honing set ontology, it is characterized in that: described The full-shape α of the conical surface of taper push rod is 2-2.5 degree and left end is equipped with axial threaded hole；The side of the honing set ontology is equipped with It penetrates through axial opening and left end is equipped with flange.

Further, six oilstones are welded in honing set ontology right part, six oilstones cover this along the honing Body is circumferentially uniformly distributed.

Preferably, the full-shape α of the conical surface of the taper push rod is 2.29 °.

Further, the taper push rod and honing set ontology are connect with universal feeding machine structure.

Compared to the prior art the utility model has the advantage that

(1) honing set ontology and taper push rod (i.e. feeding cone) use full taper-face contact, and the two cooperates without any gap, So all oilstone positions can be supported, make honing head rigidity with higher, so that it is steady to improve hone processing course It is qualitative, it ensure that the high-precision of the product processed.

(2) honing set ontology and taper push rod are cooperated using Small Taper；The full-shape α of the conical surface selects less than 2.5 ° (general steel 8 ° of material can be self-locking), therefore there is height self-locking performance, it prevents taper push rod from voluntarily retreating, improves steady in honing process It is qualitative.

(3) weld together for the oilstone of honing and honing set ontology, form an entirety, avoid traditional honing head With glue bonding oilstone, oilstone generation allows knife phenomenon in honing process；Several oil stone bases are avoided the occurrence of to swell inconsistent show As improving the precision of honing head.

(4) this precision shell type honing head is connected through a screw thread mode and connect with general feed mechanism.Honing head replacement side Just.

Specific embodiment

Below in conjunction with attached drawing, the utility model will be further described.

Referring to fig. 2, Fig. 3 and a kind of accurate shell type honing head for Horizontal honing machine shown in Fig. 4, including taper push rod 1, the honing of the outside of inner wall and taper push rod cooperation covers ontology 2, is fixed on upper a plurality of oilstone 3 outside honing set ontology, special Sign is: the full-shape α of the conical surface of the taper push rod 1 is 2 ° -2.5 ° and left end is equipped with axial threaded hole 11；The honing set is originally The side of body 2 is equipped with the axial opening 21 of perforation and left end is equipped with flange.Taper push rod is connect with honing set ontology using the full conical surface Touching can support all forced positions of honing set ontology, to improve the feed accuracy of honing stone.

Six oilstones 3 are welded in honing set 2 right part of ontology, six oilstones 3 cover ontology 2 weeks along the honing To being uniformly distributed.Traditional honing head glue bonding oilstone is avoided, oilstone generation allows knife phenomenon in honing process.

Preferable scheme is that: the full-shape α of the conical surface of the taper push rod 1 is 2.29 ° (taper of 1:100).The conical surface it is complete Angle α is selected less than 2.5 °, therefore has height self-locking performance, taper push rod can be effectively prevent voluntarily to retreat, to improve honing Stability in journey.

The taper push rod 1 and honing set ontology 2 are connect with universal feeding machine structure.

Referring to Fig. 5, Fig. 6 and Fig. 7, the universal feeding machine structure includes honing head body 4, and the center of the honing head body is equipped with The middle part of the stepped hole of perforation, preceding push rod 41 and stepped hole cooperates, and the outside of preceding push rod is equipped with limiting slot, the limiting slot and radial direction Across 4 middle part fastening bolt of honing head body, 42 corresponding matching；The axial screw of the right end of preceding push rod 41 and 1 left end of taper push rod Pit 11 is cooperatively connected, and the flange of the honing set 2 left end of ontology is adapted with the right part of the stepped hole on honing head body, and is led to A loose joint nut 43 is crossed to connect with the left end of the honing head body 4.

Basic principle is: taper push rod turn right propulsion make honing set ontology uniformly swell, and make honing set ontology outer circle on Oilstone uniformly increase, to allow oilstone contact workpiece, realize honing.

The shortcomings that the utility model changes traditional single conical surface contact structure form, compensates for traditional honing head, this reality With novel by Reusability, and the processing of the precision pair for sizes aperture, effect also is obtained, effectively Solves the hole precision honing technique problem of the honing precision pair part on Horizontal honing machine.
