Detailed description of the invention
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further detailed.
As shown in fig. 3 to 7, the assistant pressing tool of a kind of valve oil seal that the utility model embodiment provides, comprises body 11 and guide post 12.Body 11 is generally cylindrical structural, and the diameter of mid portion is slightly less than the diameter at two ends, so that hand-held; A rectangular surfaces can also be milled out, for marking in addition at mid portion.One end end face of body 11 has prepackage hole 113, guide post 12 is installed in described prepackage hole 113, the axis of guide post 12 overlaps with the center line in described prepackage hole 113, and to ensure to press-fit precision, guide post 12 can be slidably matched through valve oil seal 21 and valve guide bushing 22.Described herein being slidably matched refers to there is certain fit clearance between guide post 12 and valve guide bushing 22, and guide post 12 can moving axially along valve guide bushing 22.
Press-fit in process, first valve oil seal 21 is positioned in prepackage hole 113 through guide post 12, then the valve oil seal 21 on assistant pressing tool is aimed at valve guide bushing 22, the other end of assistant pressing tool is knocked with "painted-face" character in opera, guide post 12 is along the axially-movable of valve guide bushing 22, valve oil seal 21 is enclosed within valve guide bushing 22 in the direction simultaneously, until one end of valve oil seal 21 is against on the step surface of cylinder cap 23, extracts assistant pressing tool.In said process, guide post 12 ensure that along valve guide bushing 22 axially-movable and press-fits direction, compared to the content introduced in background technology, the assistant pressing tool that the utility model provides has guide effect, to press-fit in process valve oil seal 21 not easily crooked causing press-fit warpage.
In practical application, press-fit direction for ensureing that valve oil seal 21 and valve guide bushing 22 contact just not depart from the beginning, one end that guide post 12 is slidably matched with valve guide bushing 22 should stretch in outward valve oil seal 21.Press-fiting in process like this, guide post 12 can contact with valve guide bushing 22 prior to valve oil seal 21, for valve oil seal 21 provides guide effect, thus ensures to press-fit direction.
Further, in the utility model embodiment, one end that guide post 12 is slidably matched with valve guide bushing 22 is simultaneously outer stretches in described prepackage hole 113.Like this before valve oil seal 21 and valve guide bushing 22 start to contact, guide post 12 can preferentially insert valve guide bushing 22, and operator can control to press-fit direction with coordinating of valve guide bushing 22 by observing the upper outside part stretching in prepackage hole 113 of guide post 12.And valve oil seal 21 is relative to the relative position of assistant pressing tool body 11, can be specifically limited according to the specification of valve oil seal 21, shape etc.
The part that guide post 12 contacts with valve guide bushing 22, because Long-Time Service will inevitably produce wearing and tearing, change after wearing and tearing for ease of guide post 12, guide post 12 and body 11 adopt and removably connect.On the other side, guide post 12 is integral type with the body 11 of assistant pressing tool, then need to change whole assistant pressing tool when wearing and tearing occur guide post 12.Comparatively speaking, the scheme that the utility model embodiment adopts not only can save material cost, can also simplify the structure of single part, be convenient to production and processing.
In the utility model embodiment, the body 11 of assistant pressing tool is also provided with guide rod installing hole 112, guide post 12 installing hole is located at the bottom in prepackage hole 113, and the center line of guide rod installing hole 112 overlaps with the center line in prepackage hole 113, and guide post 12 can directly be plugged in guide rod installing hole 112.Like this in process, guide rod installing hole 112 and prepackage hole 113 can a step completes, axiality is high, thus can ensure the positional precision in guide post 12 and prepackage hole 113.If adopt other connected modes, such as arrange bead in guide post 12 one end, bead arranges connecting hole, guide post 12 is fastened on prepackage bottom through connecting hole by screw; Then installing relatively can be more difficult, and is difficult to ensure guide post 12 and the axiality pre-installing hole 113, thus may reduce the installation accuracy of valve oil seal 21.
In addition, adopt guide post 12 after said structure to be slidably matched with guide rod installing hole 112 further, namely guide post 12 has multiple gear and connects position in guide rod installing hole 112 along own axes direction.Can, by the position of adjustment guide post 12 relative to guide rod installing hole 112, regulate guide post 12 relative to the extension pre-installing hole 113 or valve oil seal 21, to adapt to the valve oil seal 21 of different size like this.Described being slidably matched can be matched in clearance or interference fits, specifically can determine according to the installation accuracy of valve oil seal 21.
When adjust guide post 12 relative to valve oil seal 21 or prepackage hole 113 overhanging size after, need guide post 12 to fix, adopt threaded fastener to connect in the present embodiment, threaded fastener is arranged along the radial direction of guide rod installing hole 112.Particularly, screwed hole 111 can be set on the body 11 of assistant pressing tool, then use screw 13 fastening; Also on the body 11 of assistant pressing tool and guide post 12, through hole can be processed simultaneously, connect with bolt.In addition, the one end that can also be slidably matched with guide rod installing hole 112 on guide post 12 processes screw thread, with guide rod installing hole 112 threaded engagement while of such guide post 12, also can play fixation.With regard to the utility model embodiment, the first connected mode is more reliable, and does not affect the adjusting function of guide post 12.If form with bolts, in order to not affect the adjustability of guide post 12, needing on the body 11 of assistant pressing tool, to offer multiple described through hole or this through hole is extended along guide post 12 telescopic direction, such inconvenient operation, and being unfavorable for processing.Although last a kind of scheme is conducive to the adjustment of guide post 12, in use guide post 12 may loosen, fixing unreliable.Therefore the utility model embodiment preferably adopts the first connected mode.
Further, after adopting above-mentioned connected mode, one end that guide post 12 is slidably matched with guide rod installing hole 112 arranges taper seat 122, and one end of screw 13 withstands on described taper seat 122, like this can increasing friction force, improves the reliability connected.Further, no matter how the position of guide post 12 in guide rod installing hole 112 changes, and only needs to adjust being screwed into the degree of depth and can realizing fixing of screw 13, makes the structure of this assistant pressing tool simpler.
Preferably, one end end face that guide post 12 is slidably matched with valve guide bushing 22 has guide portion 121, and guide portion 121 comprises arc surface and/or taper seat.During installation, first valve guide bushing 22 is inserted in the one end with guide portion 121, arc surface or taper seat have guiding function, conveniently press-fit.
Mode above only by illustrating describes some one exemplary embodiment of the present utility model, undoubtedly, for those of ordinary skill in the art, when not departing from spirit and scope of the present utility model, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the utility model claims.
