It is put into slot, has an outer small interior big angle slot (angle and voussoir 3 are consistent) in 2 installation end of lower claw, then by voussoir 3 as schemed
4 are put into angle slot, are fastened with voussoir screw 4 and ontology 1, and lower claw 2 makes this in the case where voussoir 3 acts on tight process to external support force
Body 1 is as shown in Figure 1 as an entirety with lower claw 2.
C-type spring 13 as shown in Figure 5 processes an outer small interior big opening, in the hanging pin 9 of c-type spring as shown in Figure 6
Portion is machined with the slot of an introversion, and 9 shaft end of hanging pin of two c-type springs is connected symmetrically placed by when assembly, is blocked with c-type spring 13
Mouth is stuck in the 9 middle part introversion slot of hanging pin of c-type spring as shown in fig. 7, the effect of 13 elastic force of c-type spring is lower with two c-type springs
Hanging pin 9 is connected as one,
Measuring claw 11 as shown in Figure 8 has the slot of 6 mm pin hole and 6 mm wide of a Φ in the middle part of its thickness direction, there is 2 Φ
3 hole pin impenetrating thickness, wherein 13 hole pin of Φ and 6 mm axially bored line square crossing of Φ, in addition there is 1 on measuring claw lower end surface
R1.5 loses half slot,
Component is connected as one as shown in Figure 7 together with the hanging pin 9 of two c-type springs under the effect of 13 elastic force of c-type spring
Being put into the middle part of 1 upper thickness direction of ontology has in the cavity of 6 mm pin hole of a Φ and 6 mm wide, and the hanging pin 9 of c-type spring is placed on
In 6 mm pin hole of Φ, c-type spring 13 is fallen in 6 mm wide cavitys, because ontology 1 has one to intersect vertically with 6 mm pin hole of Φ
Φ 3mm pin hole, the hanging pin 9 of same c-type spring also have intersection Φ 3mm pin hole perpendicular to the axis, with Φ 3mm straight pin 8 by they
It links together.
Its structure of lever pin 10 as shown in Figure 9 is intermediate 6 both ends mm Φ of Φ, 3 mm Step Shaft, intermediate 6 mm axis of Φ
Length is 6 mm, its 6 mm shaft length of Φ is consistent with groove width in the middle part of ontology 1,11 thickness of measuring claw, places it into and has assembled
The complete lower hanging pin 9 with two c-type springs of 13 elastic force of c-type spring effect is connected as one two in 6 mm sipes of component body 1
1 R1.5 that end 3 mm Step Shaft of Φ is fallen on 1 upper surface of ontology loses in half slot.
By the lower other end C for being connected as one component with the hanging pin 9 of two c-type springs of 13 elastic force of c-type spring effect
One end hanging pin 9(of type spring is connected with ontology 1) measuring claw 11 is connected, and the hanging pin 9 of c-type spring is placed on 6 mm pin hole of Φ
In, c-type spring 13 is fallen in 6 mm sipes, because measuring claw 11 has one to intersect vertically Φ 3mm pin hole with 6 mm pin hole of Φ,
The hanging pin 9 of same c-type spring also has intersection Φ 3mm pin hole perpendicular to the axis, they are linked together with Φ 3mm straight pin 8.
Ontology 1 and measuring claw 11 become an entirety after connection, and at this moment bayonet end is under the effect of 13 elastic force of c-type spring, due to lever pin
10 support size is minimum, as having the tipper in 3 hole mm and 3 mm wide a Φ, slot difference position on Figure 10 hooked hand 14
The difference at a distance from hole is set, hooked hand 14 is penetrated from 1 lower end through slot of ontology until using in the cavity of 6 mm wide of measuring claw 11
The Φ 3mm pin hole that Φ 3mm fixed pin 16 penetrates measuring claw 11 connects hooked hand 14, then is worn with hooked hand's sliding pin 15 of a Φ 3mm
Enter another Φ 3mm pin hole of ontology 1 slot of 3 mm wide on hooked hand 14 is connected, due to 3 mm pin hole of Φ and 3 on hooked hand 14
Mm slot, slot different position distance is different, so measuring claw 11 and ontology 1,13 elastic force of c-type spring acts on lower measuring claw 11 and ontology
1 bayonet becomes smaller, and moving 14 measuring claw 11 of hooked hand and 1 bayonet of ontology will swing around lever pin 10 to big, may be implemented to product
Part without rub measurement.Its theoretically precision is very high as can be seen from Table I.
It measures the linearity error such as table one: L of workpiece after progress operation as follows as shown in figure 13: being measurement workpiece
Centre distance of the center to lever pin 10, (Ln arbitrary dimension), r: being workpiece radius (rn arbitrary dimension), H measurement point to lever
Centre distance is sold, (Hn arbitrary dimension), Δ: being that table corresponds to various sizes of measured value, and α n, β n and θ n are derivation process angles,
ε n: being influence value of the table measuring head diameter in any angle butt contact to lever central distance.
