Abstract
The utility model belongs to checkout equipment field, in particular to a kind of crank phase angle detection device, comprise worktable, worktable is arranged V-type support, V-type support supports the king journal of bent axle, worktable both sides arrange guide rail, guide rail can slide along worktable, between guide rail, horizontally set lifting board, arranges dial gauge above lifting board, and dial gauge is fixed on fixed support, fixed support is laterally installed between the guide rails, bent axle one end arranges index dial, and corresponding index dial arranges vernier scale, and vernier scale is fixing on the table by bracing frame.The utility model have employed circular scale dish and the instruction of calibration vernier, the angular values of this point is directly read after coordinating the dial gauge on guide rail, lifting board, fixed support to find crank throw peak, then read each crank throw angle value successively at every turn, relative plus-minus calculates the phasing degree that just can draw each crank throw, and degree of accuracy is 0.05 degree.
Description
Technical field
The utility model relates to a kind of crank phase angle detection device, belongs to checkout equipment field.
Background technology
Bent axle is the core component of engine, between each crank throw, whether angle is accurate, directly have influence on engine running, existing detection method is placed on platform by bent axle, with support supports main shaft footpath, after levelling axis, find the tidemark height number of some crank throws with height gauge dial gauge, and then look for other crank throw peak record numerical value, calculated the phasing degree that just can draw crank throw by function according to recorded numerical value.The bent axle of this detection method six crank throws needs the time of about one day, and the data of measurement draw angular values, poor accuracy by after computing several times.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of accuracy high, and measuring speed is fast, crank phase angle detection device easy to use.
Crank phase angle detection device described in the utility model, comprises worktable, worktable is arranged V-type support, V-type support supports the king journal of bent axle, worktable both sides arrange guide rail, and guide rail can slide along worktable, horizontally set lifting board between guide rail, above lifting board, dial gauge is set, dial gauge is fixed on fixed support, and fixed support is laterally installed between the guide rails, and bent axle one end arranges index dial, corresponding index dial arranges vernier scale, and vernier scale is fixing on the table by bracing frame.
Guide rail can slide along worktable, to measure each crank throw; Lifting board horizontally set between the guide rails, when crank throw arrives peak, can move upward along guide rail under the force of crank throw, when crank throw leaves peak, lifting board moves downward, and moves up and down, thus detect whether arrive peak so that promote dial gauge gauge outfit; On guide rail, longitudinally chute can be set, so that lifting board moves up and down in chute; The setting of index dial and vernier scale is convenient to after finding basic point accurately, determines the angle of each crank throw, to calculate the phasing degree between two crank throws, measures convenient, directly perceived, makes measured result accurate, improve the quality of products.
Described fixed support exceeds lifting board 5mm ~ 6mm, and dial gauge gauge outfit contacts pressure amount with lifting board be 0.3mm ~ 0.5mm.It is flexibly movable to guarantee, measures accurately, easy to use.
The beneficial effects of the utility model are:
Have employed circular scale dish and the instruction of calibration vernier, the angular values of this point is directly read after coordinating the dial gauge on guide rail, lifting board, fixed support to find crank throw peak, then read each crank throw angle value successively at every turn, relative plus-minus calculates the phasing degree that just can draw each crank throw, degree of accuracy is 0.05 degree, for six crank throw bent axles, whole testing process completed within one hour, and accuracy is higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, index dial 2, bracing frame 3, worktable 4, V-type support 5, guide rail 6, vernier scale 7, lifting board 8, fixed support 9, dial gauge 10, crank throw 11, king journal.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, crank phase angle detection device described in the utility model, comprise worktable 3, worktable 3 is arranged V-type support 4, V-type support 4 supports the king journal 11 of bent axle, it is characterized in that: worktable 3 both sides arrange guide rail 5, guide rail 5 can slide along worktable 3, horizontally set lifting board 7 between guide rail 5, dial gauge 9 is set above lifting board 7, dial gauge 9 is fixed on fixed support 8, fixed support 8 is laterally arranged between guide rail 5, bent axle one end arranges index dial 1, corresponding index dial 1 arranges vernier scale 6, vernier scale 6 is fixed on worktable 3 by bracing frame 2.
Using method: the king journal 11 of bent axle is placed on the V-type support 4 of worktable 3 by the strong point of regulation; Index dial 1 and main bearing journal 11 are linked together fixing, after vernier scale 6 and index dial 1 relative position place, are fixed on worktable 3 by bracing frame 2; Guide rail 5 is placed on worktable 3, lifting board 7 position is adjusted to below crank throw 10 peak 1mm ~ 2mm, and fixed support 8 exceeds lifting board 5mm ~ 6mm, and is fixed on guide rail 5, installed by dial gauge 9, gauge outfit contacts pressure amount 0.3mm ~ 0.5mm with lifting board 7; Turning crankshaft finds crank throw 10 peak, reads this angle value, measure each crank throw successively, readout value by vernier scale 6 and index dial 1, any two turn between angle plus and minus calculation just can draw this two turn between phasing degree.
This checkout equipment not only can detect engine crankshaft phasing degree accurately, and can detect and have angle requirement related components in space, and efficiency is high, and precision is accurate.
