Description
Technical field
The utility model relates to a kind of fixture used in explosive motor dry liner inner bore honing process, especially can ensure a kind of dry cylinder liner honing fixture of cylinder sleeve bore circularity.
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 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.Due to during upper platen clamping, differential pressure is produced to cylinder sleeve upper surface, make cylinder-liner distortion uneven, cause endoporus circularity over tolerance; Or the circularity of retinue cover own is bad, the cylinder sleeve circularity circularity one that and then retinue is overlapped changes.
Utility model content
The utility model object provides a kind of dry cylinder liner honing fixture that can ensure cylinder sleeve bore circularity to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of dry cylinder liner 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 clamping cylinder piston and upper platen are that hemisphere face coordinates; Described upper platen and retinue are provided with protective cover between overlapping, and described protective cover is that step is circular; The step of described protective cover and the supporting of cylinder sleeve to be processed are takeed on suitable.
Preferably, rigid liner is provided with in described retinue cover.
Preferably, described rigid liner and described retinue overlap matched in clearance.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The dry cylinder liner honing fixture of the utility model scheme, upper platen is coordinated with the straight seam of clamping cylinder piston and changes hemisphere face into and coordinate, therefore described upper platen is the platen that floats, make the direction of clamping force automatically adjust during clamping take on upper surface with the supporting of cylinder sleeve vertical as far as possible, slackened the impact of clamping force pinching deformation on cylinder sleeve bore circularity; And be provided with protective cover between upper platen and cylinder sleeve, upper platen directly to be become by protective cover the focus pressure of the supporting of cylinder sleeve shoulder upper surface and disperses distribution pressure more uniformly, slackened the impact of the internal hole circle degree of clamping force further.
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;
Structural representation when accompanying drawing 2 is dry cylinder liner honing fixture clamping machining workpiece of the present utility model;
Wherein: 1, base; 2, retinue cover; 3, clamping cylinder piston; 4, cylinder sleeve; 5, upper platen; 6, protective cover; 7, rigid liner.
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 (5) above, and described upper platen (5) is connected to the lower end of clamping cylinder piston (3); Described clamping cylinder piston (3) with upper platen (5) for hemisphere face coordinates; Described upper platen (5) and retinue are overlapped between (2) and are provided with protective cover (6), described protective cover (6) for step circular; The step of described protective cover (6) and the supporting of cylinder sleeve to be processed (4) are takeed on suitable.When the dry cylinder liner honing fixture of the utility model scheme works, workpiece to be processed cylinder sleeve (4) is installed in retinue cover (2), the outside diameter of described cylinder sleeve (4) equals to accompany and overlaps the interior circular diameter of (2), its cylinder sleeve (4) supporting shoulder to be just stuck between retinue cover (2) and protective cover (6) in the cavity that formed, then go up platen (5) to be pressed on protective cover (6), and then realize the location up and down to cylinder sleeve (4); Because upper platen (5) is that hemisphere face coordinates with coordinating of clamping cylinder piston (3), therefore platen (5) is gone up for the platen that floats, make the direction of clamping force automatically adjust during clamping take on upper surface with the supporting of cylinder sleeve (4) vertical as far as possible, slackened the impact of clamping force pinching deformation on cylinder sleeve bore circularity; And be provided with protective cover (6) between upper platen (5) and cylinder sleeve (4), upper platen (5) directly to be become by protective cover (6) the focus pressure of the supporting shoulder upper surface of cylinder sleeve (4) and disperses distribution pressure more uniformly, slackened the impact of the internal hole circle degree of clamping force further.
In addition, rigid liner (7) is provided with in described retinue cover (2); Described rigid liner (7) and described retinue overlap (2) matched in clearance.The interior circular diameter of described rigid liner (7) equals the outside diameter of cylinder sleeve (4) to be processed, described rigid liner (7) adopts resilient steel material, uses front autogenous grinding shaping, can well hold cylinder sleeve tightly, better avoid cylinder sleeve cylindrical to be out of shape during processing cylinder sleeve, ensure the requirement of endoporus circularity.
Dry cylinder liner honing fixture structure described in the utility model is simple, reasonable in design, effectively can reduce cylinder sleeve supporting and take on the pressure be subject to, and then the endoporus circularity of cylinder sleeve when improve honing, rigid liner well holds cylinder sleeve tightly, avoid cylinder sleeve cylindrical to be out of shape, further ensure cylinder sleeve bore circularity.
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.
