(A)(b) pursues 2 graphs in 1 production practice, often need to add T graph 1(a) , (B) place shows inner cone and picture 2 show awl to sell, the dimension D(d) that place of this kind of work tags uses the groovy measure such as vernier calipers cannot accurate measure. To solve this one problem, we used the measurement unit that introduces as follows, can measure a D(d) size well and truly. The measurement of old way of 1 inner cone workpiece sees graph 1a, B, the measurement unit of dimension D sees a picture 3, its are basic the structure is: Pedestal 1 use magnetic force to express, clip of 3 one aspect of the matter holds fixed pinchcock in pedestal 1 on, clip of one aspect of the matter holds dial gauge of one many Cheng. the debus measuring a head that steel ball contains formerly on dial gauge, change special measure a head 4, measure a cone angle make it of 4 126 ° 52. By the graph 3 visible: D26=4C 1 of ° of Tg63 of 52/2)=2C · of =2C · Tg(126 ° .

Magnetic force express 2.

Many Cheng dial gauge 3.

Fixed pinchcock 4.

Measure a head 5.

Workpiece 6.

Bolt pursues 3 graphs 4 use methods: Move above all this clamping apparatus, make measure a 4 needles to contact B zero of face general dial gauge. Move after that measure a taper hole of the workpiece that insert a person, numerate dial gauge reading (it is C) namely, of this reading 4 times it is D of inner cone old way namely. Make measure a head 4 when should notice, measure a head to must hold pointed part, quench, grinding is rear can use. 2 outside the measurement of awl trail pursues 2 for bearing pin part drawing, the measurement unit of dimension D sees a picture 4, its are basic the structure is similar to measure inner cone, change merely measure a head 4; The inner cone that measure a head machines 126 ° 52; According to what measuring work measure certain measure D is some integer (D should make accurate) , get on this numeric and clear designation at F face. Use method: Will measure a 4 underside C to put face of park workpiece B above all, move dial gauge zero after that measure a head at measuring the place, numerate C of dial gauge indication, what measure 26=D-4C of ° of · Tg63 of workpiece trail D=D-2C, measure head sign indication to decrease the reading of 4 times to be workpiece trail dimension namely namely.
