Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1; The structural representation of the quick cubing 100 of the center pit degree of depth that it provides for the utility model preferred embodiments; The quick cubing 100 of the center pit degree of depth is used to measure the degree of depth of treating gaging hole, in this embodiment, mainly refers to the degree of depth of the center pit of measurement front axle.The quick cubing 100 of the center pit degree of depth comprises being housed in saidly to be treated the steel ball 10, fixed support 20, dial gauge 30 in the gaging hole and dial gauge 30 is installed in the dial gauge clamping mechanism 40 on the fixed support 20.
Fixed support 20 offers through hole 21, and through hole 21 vertically runs through fixed support 20.Dial gauge clamping mechanism 40 is used to step up dial gauge 30, must not hold tension and make dial gauge 30 distortion, so that its gauge head can't freely be beated.Dial gauge clamping mechanism 40 comprises screw 41 and is set in the tight loop 43 in the through hole 21 that in this embodiment, through hole 21 is the ladder intercommunicating pore.
Dial gauge 30 comprises gauge outfit 31; Gauge outfit 31 is through tight loop 43 and outside through hole 21 extends in fixed support 20; And be held in and be housed in the said steel ball of treating in the gaging hole 10, preferably, gauge outfit 31 sees through through hole 21, and to extend in fixed support 20 outer length be 1 millimeter.The end face of gauge outfit 31 is that plane and a side adjacent with fixed support 20 are parallel, thereby the adjacent side of the gauge head end face of principal security dial gauge 30 (being the end face of gauge outfit 31) and fixed support 20 is parallel.Screw 41 locks are paid on fixed support 20 sidewalls, be used for clamping tight loop 43 gauge outfit 31 is fastened on fixed support 20, are appreciated that the quantity of screw 41 can be no less than one, and as in this embodiment, the quantity of screw 41 is two.
In this embodiment, greater than the diameter of ladder intercommunicating pore 21 away from an end of dial gauge 30, tight loop 43 is housed in the bigger end of diameter to ladder intercommunicating pore 21 near the diameter of an end of dial gauge 30, can make things convenient in the vertical direction to settle tight loop 43 like this.Certainly in other embodiments, ladder intercommunicating pore 21 also can be less than the diameter of ladder intercommunicating pore 21 away from an end of dial gauge 30 near the diameter of an end of dial gauge 30.
The quick cubing 100 of the center pit degree of depth is mainly utilized: geometrical principle, and promptly equal according to the section of vertical line everywhere of parallel surface principle through measuring any place Face Parallel Clearance, is confirmed the height of steel ball, and then definite center pit degree of depth; Mechanical designing technique promptly guarantees that through design the right alignment of endoporus and cylindrical of verticality and the tight loop of support bracket fastened hole and end face guarantees the depth of parallelism of gauge head end face and tested center pit end face.The operating process of the quick cubing 100 of the center pit degree of depth is following:
1, tight loop 43 is packed in the fixed support 20,0-10/0.01 dial gauge 30 is packed in the tight loop 43 again, gently tighten solid screw 41 and clamp dial gauges 30, whether inspection dial gauge 30 gauge heads move sensitive;
2, the quick cubing 100 of the center pit degree of depth is lain on the platform, the position of adjustment dial gauge 30 in tight loop 43 guarantees that the gauge head end face exposes about 1mm, and the adjustment dial plate is to zero;
When 3, measuring the B4 center pit; φ 8 steel balls 10 are put into the B4 center pit, let steel ball 10 get in the interstitial hole (being through hole 21) of fixed support 20, read the dial gauge scale; Confirm the center pit degree of depth (the other types center pit detects according to the size of the definite steel ball of its size again).
In sum, the quick cubing of the center pit degree of depth that the utility model provides adopts dial gauge, through guaranteeing the flat of dial gauge gauge head end face and center pit end face, makes dial gauge measure final data and reduces reading error.The quick cubing of the said center pit degree of depth can be measured single center pit, and two ends thimble mensuration need possess two center pits; And measure accurately fast, and measurement and control center's hole collar extension diameter error is bigger.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
