Abstract
For solving the operating difficulties that prior art crankcase cylinder face size detecting method exists, being difficult to ensure the problems such as the accuracy of test, the utility model proposes a kind of crankcase cylinder face cubing.The utility model crankcase cylinder face cubing, comprises surveyor's staff, milscale and test handle, and milscale detection head axis and surveyor's staff plane perpendicular are sleeved on surveyor's staff center; Test handle is L shape, the upper end on its long limit of L shape is connected with milscale measuring head and both axis coaxle, the minor face of L shape test handle is bent to form detection head to the inside, and its cross sectional shape is for being inverted isosceles triangle, and the intersection of two waists and milscale measuring head axis are on a plane; The through hole front of surveyor's staff suit milscale is provided with adjusting bolt.The Advantageous Effects of the utility model crankcase cylinder face cubing certainly can be about to test arbor line overlap with perpendicular radii, and size reading is accurate, and structure is simple, easy and simple to handle.
Description
Technical field
The utility model relates to crankcase cylinder face detection technique, is related specifically to a kind of crankcase cylinder face cubing.
Background technology
Crankcase is generally aluminum alloy die casting, and its shape is comparatively complicated, various hole and face more, and position and size dimension require strict.In numerous various hole, spindle hole beyond doubt most important hole, except self position and size dimension require strict except, itself and other hole and the position in face and the requirement of size dimension also very strict.A plane be connected with cylinder (being commonly referred to cylinder face) is had in the oblique upper of spindle hole, comparatively strict to the required distance at spindle hole center to cylinder face, need to detect it.But, because cylinder face and the vertical radius of spindle hole have an angle, therefore, detect comparatively difficulty.Prior art crankcase cylinder face size detecting method adopts the detection cylinder matched with spindle hole to insert in spindle hole, vernier height gauge is adopted to extend into cylindrical circumference face from cylinder face, cylindrical circumference face (i.e. spindle hole radius) distance to cylinder face is detected, adds spindle hole radius after obtaining physical size and be the distance of cylinder face to spindle hole center.For ensureing accuracy of detection, the test lead axis of vernier height gauge must just overlap to the radius of cylinder perpendicular to cylinder face.But in actual test process, the test lead of vernier height gauge needs to release by artificial, the axial location of test lead also needs by artificial visually examine, not only operating difficulties, and be difficult to ensure that test lead axis overlaps with perpendicular radii, be difficult to the accuracy ensureing test.Obviously, prior art crankcase cylinder face size detecting method also exists operating difficulties, is difficult to the problems such as the accuracy ensureing to test.
Summary of the invention
For solving the operating difficulties that prior art crankcase cylinder face size detecting method exists, being difficult to ensure the problems such as the accuracy of test, the utility model proposes a kind of crankcase cylinder face cubing.The utility model crankcase cylinder face cubing, comprises surveyor's staff, milscale and test handle, and milscale detection head axis and surveyor's staff plane perpendicular are sleeved on surveyor's staff center; Test handle is L shape, the upper end on its long limit of L shape is connected with milscale measuring head and both axis coaxle, the minor face of L shape test handle is bent to form detection head to the inside, and its cross sectional shape is for being inverted isosceles triangle, and the intersection of two waists and milscale measuring head axis are on a plane; The through hole front of surveyor's staff suit milscale is provided with adjusting bolt.
The Advantageous Effects of the utility model crankcase cylinder face cubing certainly can be about to test arbor line overlap with perpendicular radii, and size reading is accurate, and structure is simple, easy and simple to handle.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic three dimensional views of crankcase;
Accompanying drawing 2 is prior art crankcase cylinder face detection method schematic diagram;
Accompanying drawing 3 is the structural representation of the utility model crankcase cylinder face cubing;
Accompanying drawing 4 is adopt the utility model cubing to carry out the schematic diagram detected.
Below in conjunction with the drawings and specific embodiments, the utility model crankcase cylinder face cubing is further described.
Embodiment
Accompanying drawing 1 is the schematic three dimensional views of crankcase, and accompanying drawing 2 is prior art crankcase cylinder face size detecting method schematic diagram, and in figure, 1 for detecting cylinder, and 2 is vernier height gauge, and A is spindle hole, and B is cylinder face.As seen from the figure, there is a plane be connected with cylinder (being commonly referred to cylinder face B) in the oblique upper of crankcase spindle hole A, comparatively strict to the required distance at cylinder face B to spindle hole A center, need to detect it.Prior art crankcase cylinder face size detecting method adopts the detection cylinder 1 matched with spindle hole to insert in spindle hole, vernier height gauge 2 is adopted to extend into cylindrical circumference face from cylinder face, cylindrical circumference face (i.e. spindle hole radius) distance to cylinder face is detected, adds spindle hole radius after obtaining physical size and be the distance of cylinder face to spindle hole center.
Accompanying drawing 3 is the structural representation of the utility model crankcase cylinder face cubing, and accompanying drawing 4 is adopt the utility model cubing to carry out the schematic diagram detected, in figure, 3 is the utility model crankcase cylinder face size checking device, 31 is surveyor's staff, and 32 is milscale, and 33 is test handle.As seen from the figure, the utility model crankcase cylinder face cubing, comprise surveyor's staff 31, milscale 32 and test handle 33, milscale 32 detection head axis and surveyor's staff 31 plane perpendicular are sleeved on surveyor's staff center; Test handle 33 is L shape, the upper end on its long limit of L shape is connected with milscale measuring head and both axis coaxle, the minor face of L shape test handle is bent to form detection head to the inside, and its cross sectional shape is for being inverted isosceles triangle, and the intersection of two waists and milscale measuring head axis are on a plane; The through hole front being set with thousand point of 32 chi at surveyor's staff 31 is provided with adjusting bolt.When adopting the utility model crankcase cylinder face cubing to detect, surveyor's staff bottom surface is placed on cylinder face, simultaneously, the detection head of test handle lower end is placed in crankcase spindle hole inner circle, because two waist intersections of test handle detection head and milscale measuring head axis are on a plane, test handle upper end is connected with milscale measuring head and both axis coaxle, milscale detection head axis and surveyor's staff plane perpendicular are sleeved on surveyor's staff center, therefore, can ensure that test arbor line overlaps with perpendicular radii, and not need range estimation or carry out other adjustment.And adopt milscale, not only reading is directly perceived, but also improves precision.Adopt adjusting bolt can regulate test handle length, with adapt to different main pitch-row from detection, the test handle changing different semi arch radius can adapt to the detection of different pore size spindle hole.
The Advantageous Effects of the utility model crankcase cylinder face cubing certainly can be about to test arbor line overlap with perpendicular radii, and size reading is accurate, and structure is simple, easy and simple to handle.
