In the manufacture process of conventional small commercial or alternator for vehicle or engine, end cap many employings metal casting of generator or engine forms, and in order to ensure rigidity and weight reduction, it adopts aluminium alloy casting; Generally all need to leave process redundancy in the process of casting, carry out cut more afterwards, become finished product.
In order to adapt to the matching requirements of end cap, need the relative dimensions controlling end cap, therefore need to carry out dimensional measurement after finalization of the manufacture, it is qualified to guarantee.End cap 10 as shown in Figure 1, it is most regular circumferential that its outward appearance has, qualified in order to ensure its fitted position, needs to carry out dimension control after finalization of the manufacture, to guarantee that the circular constant of the periphery 101 of end cap 10 is in scope of design; Conventional way utilizes kind of calliper diameter, multimetering, gets average; Then after comprehensive every size, whether qualified with the casting and processing of determining end cap.
Traditional way is manual measurement, this kind of mode time and effort consuming, and detection efficiency is low, poor reliability, and manual measurement error rate is high, easily tired, have certain technical requirement, and the error of measurement own is comparatively large, not precisely to operating personnel.
Summary of the invention
For above problem, the object of this invention is to provide a kind of small-sized end cover surface circularity dial type measuring instrument, detect effectively reliably, directly perceived, efficiency is high, and error rate is low, to human users without technical requirement, is beneficial to manual operation and not easily produces fatigue; And cubing operating accuracy is high, cost of manufacture is low, and make and easily process, spare part is easily changed, and interchangeability is strong.
For realizing above object, the technical solution used in the present invention is: a kind of small-sized end cover surface circularity dial type measuring instrument, it comprises pedestal (1), described pedestal (1) is horizontally disposed with flexible clamp (3) by vertical main vertical rod (2), described elasticity clamp (3) is provided with dial gauge (4); Described main vertical rod (2) is other is provided with supporting seat (7), and described supporting seat (7) upper surface is provided with some back-up blocks (8) for spacing end cap to be measured; The indicator of described dial gauge (4) points to described supporting seat (7).
Further, the below of described supporting seat (7) is connected with turntable (5), and described turntable (5) is rotatably connected on pedestal (1) by the rotating connector (9) be embedded on pedestal (1).
Further, described brace table (7), turntable (5) are truncated cone-shaped, and the radius of described turntable (4) is greater than the radius of brace table (7).
Further, described rotating connector (9) is ball bearing.
Further, the center hollow of described brace table (7), turntable (5), and communicate with rotating connector (9) mounting hole of pedestal (1).
Further, the side of described turntable (5) is provided with handle (6).
Principle of work of the present invention: we know that qualified product has a metrics range, all qualified within the scope of this; This place uses the ultimate principle of gauge block, and make use of the attribute of dial gauge, the circular constant (i.e. diameter dimension change) of part is converted into the pointer display of dial gauge, and reflect that whether the size of part is qualified intuitively by the deflection of the indicator of dial gauge, so, avoid the operation of artificial very complicated, and measure accurately directly perceived, and precision is high, not easily produce fatigue.
Beneficial effect of the present invention: 1, reflect that whether the size of part is qualified intuitively by the deflection of the indicator of dial gauge, detects effectively reliably, directly perceived, efficiency is high, and error rate is low.
2, to human users without technical requirement, simple, be beneficial to manual operation and not easily produce fatigue.
3, cubing operating accuracy is high, and precision reaches 0.01mm, and cost of manufacture is low, and make and easily process, spare part is easily changed, and interchangeability is strong.
