Abstract
The utility model relates to an elastic honing head, which is formed by connecting a honing pole and an elastic sleeve into a whole by a drive mechanism, wherein the elastic sleeve is a sleeve with four or more spiral chip flutes thereon; one end of each spiral chip flute is provided with an opening, and the other end is provided with a sealing; moreover, the opening and the sealing of each flute are distributed in a mutual staggered mode; the honing pole matches with the corresponding spiral chip flutes on the elastic sleeve in a floating mode and is connected into a whole with the spiral chip flutes by pulling teeth on the drive mechanism, and the number of the pulling teeth matches with the number of the spiral chip flutes. The external surface of the elastic sleeve is plated or adhered with abrasive materials. When the utility model works, the honing pole drives a drive sheet by the connection of a spline. The pulling teeth on the drive sheet match with the spiral chip flutes on the elastic sleeve in a floating mode so as to drive the elastic sleeve to rotate and perform reciprocating honing processing. The honing pressure can be adjusted by adjusting and tightly pressing a butterfly-shaped elastic sheet by a cap. The elastic sleeve can directly perform pressurizing and processing to the walls of holes. The contact area is large, so the processing and the centering are good. The utility model has the advantages of strong applicability, sensitive float and high productive efficiency, and is a honing tool with simple structure, high speed and efficiency and high precision.
Description
Technical field
The utility model relates to and a kind of the workpiece endoporus is carried out precision machined instrument, particularly a kind of elastic honing heads that suits to carry out honing processing on multiple processing equipment.
Background technology
In machining, the Precision Machining of workpiece endoporus is difficult together processing technology.Along with the manufacturing development of modern mechanical, the Precision Machining in high-precision requirement, special material, big L/D ratio and blind hole structure hole is more and more.And honing is to carry out the precision machined effective process means of endoporus, but tradition is carried out honing and is processed employed honing head, its structure generally is that the honing emery stick is clamped on the fixed mount, inclined-plane on the fixed mount and the cone match on the feed bar realize the radial feed of emery stick by the axial location that changes feed bar.Though feed bar axially can add loading damp spring regulating honing pressure, hole wall is not to be directly passed to damping spring to the pressure of emery stick, moves but the cone match of the inclined-plane by fixed mount and feed bar promotes feed bar.Obviously the insensitive and complex structure of this mechanical feeding damping mechanism reaction, when the grinding characteristic of form accuracy, surface roughness and the material in or hole improper when the feeding adjustment changes in honing processing, cause stuck bistrique phenomenon easily, even cause workpiece and bistrique to damage.In addition, because whole grinding wheel head structure complexity, honing head can not be done very for a short time, and therefore, original honing head also is not suitable for the processing of aperture.It is same because on the said structure, the blind hole bottom also can't completely process.
Number of patent application 93102082.4 " improved honing mandrel construction " also provides a kind of honing head, but its structure is more complicated, difficult again processing, poor practicability.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of high speed, efficient, high-precision elastic honing heads are provided, and simple in structure, suit on various processing equipments, to install and use, and the production efficiency height, can satisfy various processing requests, and crudy is good.
The technical scheme in the invention for solving the above technical problem is: elastic honing heads is made of through the integral body that driving mechanism and resilient sleeve connect into honing lever, described resilient sleeve is for there being the cover of 4 or 4 above spiral chip flutes on it, described honing lever by on the driving mechanism and spiral chip flute quantity be complementary pull out tooth, cooperate with spiral chip flute corresponding on the resilient sleeve is unsteady, connect in aggregates.One end opening of spiral chip flute, the other end seals, and opening, seals mutually and be in staggered distribution, and the outer surface plating of resilient sleeve has high performance honing material, directly or by driving chip is fixed on the honing lever and pull out tooth.
Compared with prior art, advantage of the present utility model is: this honing head is directly exerted pressure to the honing hole wall by the resilient sleeve of band spiral chip flute and is implemented honing processing, add that honing lever is connected with the involute spline self-centering of driving chip and the full floating of driving chip and resilient sleeve links, whole drive system self adaptation is good, be quick on the draw, precision stability is good, and the grinding performance susceptibility of form accuracy, surface roughness and the material in hole is reduced, can not produce the bistrique stuck phenomenon man-hour adding.In addition, the processing of resilient sleeve can reach higher form accuracy, thereby the form error in hole had correcting action preferably, can regulate honing pressure easily by the dish-shaped shell fragment pressure of regulating two ends, and can make pressure at two ends not wait the tapering that is beneficial to trimming hole.Resilient sleeve coating surface area is big, and the grinding efficiency height can plate again after the coating wearing and tearing, so resilient sleeve can be repeatedly used.The spiral chip flute on resilient sleeve surface makes that inwall is with holes, the processing of the inner bore honing of groove becomes feasible easily.During less or blind hole, can adopt the structure of simplifying honing head when the aperture, honing lever be floated with resilient sleeve be connected, the work of drive resilient sleeve.Can process less hole or blind hole is carried out back chipping processing, processing accommodation is wide.

The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing embodiment.
Driving chip 4 endoporus are processed into the internal spline 11 of involute spline, and outer rim is processed with 4 protrusion cylinders and pulls out tooth 7.And make the groove number that pulls out the spiral chip flute that ading up to of tooth be mated on the honing head identical.
Driving mechanism be driving chip 4 or directly be fixed on moving tooth 7 on the honing lever 1 '.
At first two driving chips 4 are pressed fit into the two ends of resilient sleeve 5 respectively, and the moving tooth 7 insertion resilient sleeve spiral chip flutes 8 on driving chip 4 outer rims are sealed in the circular hole of 10 ends, making driving chip 4 insert resilient sleeve spiral chip flute 8 with respect to 7 by assemblage gap seals in the circular hole of 10 ends, make driving chip 4 a certain amount of free floating be arranged by assemblage gap with respect to resilient sleeve 5, then honing lever 1 is inserted the endoporus of driving chip 4, external splines 12 on the honing lever 1 is matched with internal spline 11 on the driving chip, and can be in axial sliding, load onto dish-shaped shell fragment 3 at last at the two ends of resilient sleeve 5, and with also cap 2 adjustment are also tight, honing head is promptly assembled and is finished, as shown in Figure 1.
During use, honing head is installed in that main shaft can rotate and vertical honing machine, vertical boring mill or the drilling machine of axially reciprocating on carry out honing processing.
As required, also can honing lever 1 ' on directly process upper and lower two row, respectively have 4 protrusion cylinders pull out tooth 7 ', and the resilient sleeve 5 of cylinder-shaped thin wall cover ' on process corresponding 8 spiral chip flutes 8 ', by honing lever 1 ' on 8 pull out tooth 7 ', directly and resilient sleeve 5 ' on 8 seal 10 ' be connected integral body, be made into simplified structure, by honing lever 1 ' rotation, by pulling out the whole resilient sleeve 5 of tooth 7 ' drive ' rotation on it, carry out the honing processing of aperture and blind hole back chipping, as shown in Figure 2.
