Abstract
The utility model relates to a kind of dry cylinder liner inner bore honing fixture, comprises base and cylinder sleeve clamping device; Described cylinder sleeve clamping device comprises retinue cover and clamping cylinder piston; Described retinue cover is fixedly connected on base; Be provided with platen above described retinue cover, described upper platen is connected to the lower end of clamping cylinder piston; Described retinue cover is the non-uniform thickness opening sleeve of inside and outside circle decentraction; The excircle of the open side of described retinue cover is equidistantly provided with three and holds oil cylinder tightly.Dry cylinder liner inner bore honing fixture described in the utility model, structure is simple, reasonable in design, eliminate the gap of retinue cover and cylinder sleeve, " cutter relieving " phenomenon of the little cylindrical of cylinder sleeve is overcome in honing process, both solved and takeed on the problem that the processing suitable for reading of corresponding endoporus forms " upper horn mouth " afterwards with supporting, turn improved grinding efficiency.
Description
Technical field
The utility model relates to a kind of fixture used in explosive motor dry liner inner bore honing process, especially can prevent a kind of dry cylinder liner inner bore honing fixture cylinder sleeve bore being formed " horn mouth " after hole machined.
Background technology
Dry cylinder liner refers to the cylinder sleeve directly do not contacted with cooling water in engine working process, during assembling, cylindrical and cylinder body generally take interference fits, wall thickness is generally not more than 4mm, because wall is thinner, so the difficult point just having become producer to pay close attention in the control of process to distortion, be especially out of shape more complicated inner bore honing operation.
At present, common dry cylinder liner inner bore honing fixture, be made up of retinue cover and clamping cylinder, upper platen is driven to realize clamping and release action by moving up and down of clamping cylinder piston, upper platen is pressed on the supporting shoulder of cylinder sleeve, realizes locating up and down, and excircle orientation is realized by retinue cover, retinue cover is a kind of matched in clearance with cylinder sleeve, and general gap is within 0.12mm.Because the supporting shoulder of cylinder sleeve in honing process is killed by upper platen, and this place's wall is thicker, can not be swelled by honing abrasive belt, actual is high-rate grinding, and swelled by honing abrasive belt in the little excircle part honing process of cylinder sleeve, extremely could realize grinding at retinue cover inwall until paste, the hole taper corresponding with little cylindrical can be ensured by adjustment bistrique stroke, but be formed after takeing on the processing suitable for reading of corresponding endoporus with supporting " upper horn mouth ".
Utility model content
The utility model object provides to overcome the deficiencies in the prior art a kind of dry cylinder liner inner bore honing fixture preventing from cylinder sleeve bore being formed " horn mouth " after hole machined.
For achieving the above object, the technical solution adopted in the utility model is: a kind of dry cylinder liner inner bore honing fixture, comprises base and cylinder sleeve clamping device; Described cylinder sleeve clamping device comprises retinue cover and clamping cylinder piston; Described retinue cover is fixedly connected on base; Be provided with platen above described retinue cover, described upper platen is connected to the lower end of clamping cylinder piston, it is characterized in that: described retinue cover is the non-uniform thickness opening sleeve of inside and outside circle decentraction; The opening that described retinue puts is positioned at the thinnest side of retinue sleeve wall thickness; The spaced set of open side of described retinue cover has multiplely holds oil cylinder tightly.
Preferably, hold oil cylinder described in tightly and have three.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The dry cylinder liner inner bore honing fixture of the utility model scheme, the non-uniform thickness opening sleeve of inside and outside circle decentraction made by its retinue cover, and realize clamping and release action by holding oil cylinder tightly, ensure clamping rear retinue cover endoporus fourth contact by adjustment opened gap, and size is suitable with the little outside diameter of cylinder sleeve to be processed.The dry cylinder liner inner bore honing fixture of this structure, eliminate the gap of retinue cover and cylinder sleeve, in honing process, overcome " cutter relieving " phenomenon of the little cylindrical of cylinder sleeve, both solved and takeed on the problem that the processing suitable for reading of corresponding endoporus forms " upper horn mouth " afterwards with supporting, and turn improved grinding efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of dry cylinder liner honing fixture of the present utility model when clamping cylinder sleeve to be processed;
Accompanying drawing 2 is the A-A sectional view of dry cylinder liner honing fixture of the present utility model;
Wherein: 1, base; 2, retinue cover; 3, clamping cylinder piston; 4, upper platen; 5, opening; 6, oil cylinder is held tightly; 7, cylinder sleeve.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As accompanying drawing 1,2 is depicted as dry cylinder liner honing fixture described in the utility model, comprise base 1 and cylinder sleeve clamping device; Described cylinder sleeve clamping device comprises retinue cover 2 and clamping cylinder piston 3; Described retinue cover 2 is fixedly connected on base 1; Described retinue cover 2 is provided with platen 4 above, and described upper platen 4 is connected to the lower end of clamping cylinder piston 3; Described retinue cover 2 is the non-uniform thickness opening sleeve of inside and outside circle decentraction; Opening 5 on described retinue cover 2 is positioned at the thinnest side of retinue cover 2 wall thickness; The open side spaced set of described retinue cover 2 has multiplely holds oil cylinder 6 tightly.During dry cylinder liner honing fixture work described in the utility model, workpiece to be processed cylinder sleeve 7 is installed in retinue cover 2, realize unclamping then clamping cylinder sleeve 7 to be processed by holding oil cylinder 6 tightly, ensure clamping rear retinue cover 2 endoporus fourth contact by adjustment opening 5 gap, and the little outside diameter of size and cylinder sleeve 7 to be processed is suitable.Dry cylinder liner honing fixture in the present embodiment, described in hold oil cylinder spaced set tightly and have three, to ensure that holding oil cylinder 6 tightly clamps the even fourth contact of retinue cover 2 endoporus.
Dry cylinder liner honing fixture structure described in the utility model is simple, reasonable in design, the non-uniform thickness opening sleeve of inside and outside circle decentraction made by its retinue cover, and realize clamping and release action by holding oil cylinder tightly, after ensureing clamping by adjustment opened gap, retinue cover endoporus restores, and size is suitable with the little outside diameter of cylinder sleeve to be processed.The dry cylinder liner inner bore honing fixture of this structure, eliminate the gap of retinue cover and cylinder sleeve, in honing process, overcome " cutter relieving " phenomenon of the little cylindrical of cylinder sleeve, both solved and takeed on the problem that the processing suitable for reading of corresponding endoporus forms " upper horn mouth " afterwards with supporting, and turn improved grinding efficiency.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
