Abstract
The utility model discloses a skirt sleeve type line measuring tool for pistons, which comprises a base, a stop lever, a guide rail and dial gauges. The stop lever and the guide rail are perpendicularly fixed to the upper end surface of the base, and all four dial gauges are perpendicularly connected with the guide rail. The skirt sleeve type measuring tool can position measured positions accurately, greatly eliminates unstable human factors during measurement by the aid of an outside micrometer, and improves accuracy of detected data.
Description
Technical field
The utility model relates to a kind of piston skirt molded lines measurer, particularly a kind of GEVO piston skirt cover molded lines measurer.
Background technology
The GEVO piston is used for the HXN5 type locomotive, the discharging of this diesel locomotive, energy consumption, starts shipment acceleration and dynamic performance is all reached advanced world standards.
Because along its short transverse Temperature Distribution very inhomogeneous (head temperature height, the skirt section temperature is low), and material thickness is also different on each cross section during pistons work, so the swell increment in each cross section of piston is also different, up big and down small.For satisfying the low emission of HXN5 type locomotive, low energy consumption and remarkable power performance requirement, piston shape under operating mode gets subcylindrical, keep little and uniform gap with cylinder sleeve, so the skirt cover is made up-small and down-big a series of profiles, the skirt nested structure as shown in Figure 1.
For GEVO piston skirt cover, we are by controlling four sectional dimensions, each cross section is measured major diameter reference mark, minor axis diameter reference mark respectively and is located the diameter reference mark for 45 ° with the minor axis angle, reach the purpose of the whole molded lines size of control, and our currently used measurer is an outside micrometer, detects the cylindrical molded lines by the control item spot size of measuring four cross sections one by one.But, detect with outside micrometer and then following point can occur: 1, because when measuring outside dimension with outside micrometer, at first must find the cross section axial location accurately, even if but the testing staff of specialty also can't find the axial location in these cross sections accurately, thereby cause personal error to increase, measurement result is inaccurate.Especially crucial for tolerance has only the major diameter of 0.02mm, in case measure inaccurately, quality accidents such as piston knock, scuffing of cylinder bore very easily appear; 2, since each cross section need measure major diameter reference mark, minor axis diameter reference mark respectively and locate the diameter reference mark for 45 ° with the minor axis angle, therefore the molded lines of each skirt cover partly has 12 control corners, also just mean and overlap to such an extent that measure 12 times, increased workman and testing staff's burden greatly for each skirt.
The utility model content
The purpose of this utility model provides a kind of piston skirt cover molded lines measurer, and is easy to use, simple to operate, can effectively increase work efficiency, and detect the accuracy height of numerical value.
The technical scheme that realizes the utility model purpose is: a kind of piston skirt cover molded lines measurer, comprise base, pin, guide rail and dial gauge, and pin and guide rail are vertically fixed on the upper surface of base, and dial gauge is provided with four, and all is connected with guide rail is vertical.
Described four dial gauges all are slidingly connected with guide rail.
A kind of piston skirt cover molded lines measurer also comprises standard skirt cover.
The utlity model has positive effect: the artificial labile factor when using outside micrometer to measure has accurately been eliminated greatly in location, (1) the utility model measuring position, has improved the accuracy that detects numerical value.
(2) dial gauge of the present utility model is provided with four, and all laterally is installed on the guide rail, needs to measure the work that ten secondaries just can be finished before this structure makes, only need can finish for three times now, has shortened about three times of man-hours, has improved work efficiency greatly.
(3) installation site of dial gauge of the present utility model on guide rail can be regulated, and this structure makes the utility model can be very easy to find accurately the position of major axis or minor axis, greatly reduces the measurement difficulty.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and according to specific embodiment also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is a GEVO piston skirt nested structure synoptic diagram.
Fig. 2 is a structural representation of the present utility model.
Label in the accompanying drawing is:
Base 1, pin 2, guide rail 3, dial gauge 4, standard skirt cover 5.
Embodiment
(embodiment 1)
See Fig. 2, present embodiment comprises base 1, pin 2, guide rail 3, dial gauge 4 and standard skirt cover 5, and pin 2 and guide rail 3 are vertically fixed on the upper surface of base 1, and dial gauge 4 is provided with four, and all with guide rail 3 vertical being slidingly connected.
This measurer one end is with pin 2 location, and an other end is four dial gauges 4, and the axial location of dial gauge 4 on guide rail 3 can be regulated.At first adjust each dial gauges 4 with standard skirt cover 5, make the pointer nulling of each dial gauge 4, measure the cylindrical molded lines of skirt cover to be measured then, the gained reading just be the difference that actual measured value and standard skirt overlap 5 size, can draw actual measured value thus.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is a specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (3)
1. a piston skirt overlaps the molded lines measurer, it is characterized in that: comprise base (1), pin (2), guide rail (3) and dial gauge (4), pin (2) and guide rail (3) are vertically fixed on the upper surface of base (1), and dial gauge (4) is provided with four, and all with vertical connection of guide rail (3).
