Abstract
The utility model relates to a boss height measuring apparatus. The boss height measuring apparatus comprises a support, a probe, a dial gauge, a spring and a base, wherein the support is provided with a step hole; the probe is in sliding fit in the step hole of the support; one end of the probe is provided with a boss; the boss on the probe extends into the small-diameter hole of the step hole; the measuring rod of the dial gauge extends into the step hole of the support; the spring is disposed in the large-diameter hole of the step hole in the support; one end of the spring is connected with the probe; the other end of the spring is connected with the measuring rod of the dial gauge; the base is connected with the support; the base is provided with a through hole; the through hole communicates with the small-diameter hole of the step hole in the support; and the hole diameter of the through hole is greater than the hole diameter of the small-diameter hole of the step hole. The boss height measuring apparatus has the advantages of high precision, convenience and rapidness.
Description
Technical field
The utility model relates to a kind of boss height measurement mechanism.
Background technology
In order to reduce impact and the ablation of combustion gas combustion motor head gasket, extend the serviceable life of head gasket, the cylinder jacket of diesel engine is generally processed with boss in supporting shoulder upper surface.Cylinder jacket boss height size directly has influence on the serviceable life of internal combustion engine, and its height dimension is generally between 0.5-1.2mm, and tolerance is within 0.10, and degree of accuracy requires high especially.At present, the producer of production cylinder jacket, majority all adopts depth vernier gage to measure.Though this kind of method can be measured the height of cylinder jacket boss, due to blade, to measure face little, easily wearing and tearing, exist measuring error large, measure trouble, the low shortcoming of vernier apparent value accuracy.
Summary of the invention
Fundamental purpose of the present utility model is to provide a kind of boss height measurement mechanism, the utlity model has degree of accuracy Gao Yiyou advantage easily and efficiently.
The technical scheme solving the problems of the technologies described above is as follows:
Boss height measurement mechanism, comprise supporting, gauge head, dial gauge, spring and base, supporting is provided with stepped hole, gauge head is slidably fitted in the stepped hole of supporting, one of gauge head is provided with boss, boss on gauge head extend in the diameter holes of stepped hole, the measuring staff of dial gauge extend in the stepped hole in supporting, spring is arranged in the hole, large footpath of the stepped hole in supporting, one end of spring is connected with gauge head, the other end of spring is connected with the measuring staff of dial gauge, described base is connected with supporting, base is provided with through hole, this through hole is communicated with the diameter holes that supports the hole of topping bar, the aperture of through hole is greater than the aperture of stepped hole diameter holes.
Through hole on described base is stepped hole, and base is connected with support thread.
Adopted such scheme, during measurement, through hole by the boss of measured workpiece from base is inserted in the diameter holes that supports the hole of topping bar, make the make progress boss of top gauge head of the boss of workpiece, the boss of gauge head is subject to after acting force upwards force transmission to spring, spring promotes the measuring staff of dial gauge, thereby on dial gauge, has corresponding reading.Step surface when workpiece convex platform and workpiece body junction, contacts and cannot further move up with supporting lower surface, illustrates that movement that boss makes progress has arrived the root of boss, and at this moment the reading on dial gauge is the height value of boss.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
1 is supporting, and 2 is gauge head, and 2a is boss, and 3 is dial gauge, and 4 is spring, and 5 is base, and 5a is through hole.
Embodiment
With reference to Fig. 1, a kind of boss height measurement mechanism of the present utility model, comprises supporting 1, gauge head 2, dial gauge 3, spring 4 and base 5.Supporting 1 is provided with stepped hole, and gauge head 2 is slidably fitted in the stepped hole of supporting, and one of gauge head is provided with boss 2a, and the boss 2a on gauge head 2 extend in the diameter holes of stepped hole.The measuring staff of dial gauge 3 extend in the stepped hole in supporting 1.In the hole, large footpath of the stepped hole of spring position 4 in supporting, one end of spring 4 is connected with gauge head 2, and the other end of spring 4 is connected with the measuring staff of dial gauge 4.Described base 5 is connected with supporting 1, and base 5 is provided with through hole 5a, and this through hole is communicated with the diameter holes that supports the hole of topping bar, and the aperture of through hole is greater than the aperture of stepped hole diameter holes.Through hole on described base is stepped hole, and base is connected with support thread.
During measurement, through hole 5a by the boss of measured workpiece from base 5 is inserted into supporting 1 and tops bar in the diameter holes in hole, make the make progress boss 2a of top gauge head 2 of the boss of workpiece, the boss 2a of gauge head is subject to after acting force upwards force transmission to spring 4, spring 4 promotes the measuring staff of dial gauge 3, thereby on dial gauge, has corresponding reading.Step surface when workpiece convex platform and workpiece body junction, contacts and cannot further move up with supporting lower surface, illustrates that movement that boss makes progress has arrived the root of boss, and at this moment the reading on dial gauge is the height value of boss.
Claims (2)
1. boss height measurement mechanism, it is characterized in that: comprise supporting, gauge head, dial gauge, spring and base, supporting is provided with stepped hole, gauge head is slidably fitted in the stepped hole of supporting, one of gauge head is provided with boss, boss on gauge head extend in the diameter holes of stepped hole, the measuring staff of dial gauge extend in the stepped hole in supporting, spring is arranged in the hole, large footpath of the stepped hole in supporting, one end of spring is connected with gauge head, the other end of spring is connected with the measuring staff of dial gauge, described base is connected with supporting, base is provided with through hole, this through hole is communicated with the diameter holes that supports the hole of topping bar, the aperture of through hole is greater than the aperture of stepped hole diameter holes.
