Technical field
The utility model relates to diesel engine field, particularly a kind of main spindle hole cubing.
Background technology
The position that the cylinder of diesel engine bottom is used for installing bent axle is called crankcase, and crankcase divides upper crankcase and lower crankcase.Upper crankcase usually and the cylinder block cast solid, lower crankcase is used for storing lubricating oil, and the sealing upper crankcase, the upper and lower lunette of spindle hole is opened in respectively on upper crankcase and lower crankcase, is formed by the upper and lower lunette closure on upper crankcase and lower crankcase.
Spindle hole is as the important mating part of crankshaft of diesel engine, require it to have higher circularity and right alignment, easily produce at faying face circularity and the right alignment that left and right dislocation (upper and lower lunette left and right is unjustified) affects spindle hole and upper and lower lunette is closed when forming whole spindle hole, larger magnitude of misalignment can affect assembling and the behavior in service of diesel engine.
(being limited to the diameter of measuring the 45° angle direction) measured in existing aperture of just adopting the stock dial bore gage to coordinate smooth master ring to detect spindle hole to the detection of main spindle hole, and in the analysis in main spindle hole, adopt traditional stock dial bore gage to detect the magnitude of misalignment that can not detect intuitively the spindle hole faying face, detect of low quality, thereby affect the assembly quality of main spindle hole.
The utility model content
The utility model is in order to overcome defective in above-mentioned prior art, to provide a kind of simple and reasonable, the magnitude of misalignment that detects the spindle hole faying face of energy simple, intuitive, the high main spindle hole cubing of detection quality.
For achieving the above object, provide a kind of main spindle hole cubing according to the utility model, comprise: support and the clock gauge that is arranged on support, support comprises: back-up block, the two ends, left and right of back-up block have respectively the isocentric circular arc end face adaptive with the hole wall circular arc of standard diesel oil owner axis hole; Clock gauge comprises: dial plate, measuring staff and gauge head, and axially vertically wear by the left-right symmetric of measuring staff along described back-up block.
In technique scheme, clock gauge is inside dial indicator.
In technique scheme, support also comprises: locking copper sheathing and lock-screw, and the sidewall of locking copper sheathing has axially open, and the measuring staff of clock gauge is inserted in the locking copper sheathing, then plug-in mounting enters back-up block; Lock-screw vertically is screwed into back-up block compression locking copper sheathing opening and fixes clock gauge.
Compared with prior art, the utlity model has following beneficial effect: this main spindle hole cubing is simple and reasonable, and the magnitude of misalignment that detects the spindle hole faying face of energy simple, intuitive is simple to operate, detects quality high.

Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.It will be appreciated that, mentioned in following embodiment of the present utility model " on ", D score, " left side ", " right side ", " front " and " reverse side " be all take the direction shown in each figure as benchmark, these words that are used for limiting direction are only for convenience of explanation, do not represent the restriction to the concrete technical scheme of the utility model.
As depicted in figs. 1 and 2, main spindle hole cubing of the present utility model is to draw (check point near faying face) of the left and right magnitude of misalignment of spindle hole on faying face through calculated difference by the aperture that the clock gauge gauge head detects respectively the upper and lower lunette of spindle hole again, and concrete structure comprises: support and be located in inside dial indicator on this support as far as possible.
Support as the core component of main spindle hole cubing comprises: back-up block 11, locking copper sheathing 12 and lock-screw 13, wherein, the upper and lower limit of back-up block 11 be arranged in parallel, from main apparent direction, the two ends, left and right have symmetrical isocentric circular arc end face 111, and the hole wall circular arc of isocentric circular arc end face 111 mock standard main spindle holes is during measurement, be used for the main spindle hole hole wall of fitting to be detected, make back-up block 11 become the round simulation tangent line in spindle hole cross section.In addition, for the main spindle hole hole wall to be detected of better fitting, chamfering is carried out in the corner of isocentric circular arc end face 111, keeps fitting with the linearity of main spindle hole hole wall to be detected as far as possible.The left-right symmetric of back-up block 11 axially offers clock gauge jack 112, the upper and lower side of clock gauge jack 112 vertical support pieces 11.Vertical clock gauge jack 112 offers locking screw holes, by lock-screw 13 locking copper sheathings 12.Lock-screw 13 adopts the M6 screw.The sidewall of locking copper sheathing 12 has axially open, is arranged in clock gauge jack 112, is used for plug-in mounting clock gauge measuring staff.
Inside dial indicator comprises: dial plate 21, measuring staff 22 and gauge head 23, telescopic measuring staff 22 front ends that are arranged on of gauge head 23.
During assembling, first will lock copper sheathing 12 plug-in mountings enters in the clock gauge jack 112 of back-up block 11, again measuring staff 22 plug-in mountings are entered to lock in copper sheathing 12, after stretching out the distance of back-up block 11 when adjusting gauge head 23 measurement, inwardly screw in by lock-screw 13 opening that compresses locking copper sheathing 12 and fix inside dial indicator.
As shown in Figure 3, during detection, this cubing is placed in spindle hole 3, the left and right isocentric circular arc end face 111 of back-up block 11 is fitted on the upper and lower lunette of spindle hole as far as possible fully, then, detect the radius of the upper and lower lunette of spindle hole spindle hole by clock gauge gauge head 23, check point is as far as possible near faying face, like this, the radius difference of the upper and lower lunette of spindle hole produces the left and right magnitude of misalignment at faying face when very forming whole spindle hole near upper and lower lunette closure, can satisfy the needs of measurement, analysis spindle hole assembly quality.
This main spindle hole cubing is simple and reasonable, and the magnitude of misalignment that detects the spindle hole faying face of energy simple, intuitive is simple to operate, detects quality high.
Above disclosed be only several specific embodiment of the present utility model, still, the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
