Embodiment
Swinging mounting 17 first, support 17 rotate around rotation seat 10, and the horizontal block 27 for turning to rotation seat 10 is in perpendicular
After straight state, universal joint standard is installed on scroll chuck 15, the horizontal block 27 for then turning to rotation seat 10 is in water
Level state, the breach 30 of the protruding block 29 of the lower end of horizontal block 27 just with fixed seat 18 interlocks, in the revolution of the bottom of actuator 13
Heart gauge head 14 extend into universal joint and (notices that centre of gyration gauge head 14 must reach over to universal joint raceway groove inwall stroke 1-2mm).
First left and right carrys out back rotation scroll chuck 15 and finds raceway groove (raceway groove position at the C shown in Fig. 5) central point, in raceway groove
Heart point is position of the pointer of measuring instrumentss 11 when 0 graduation mark has been spot wobble, and measuring instrumentss 11 typically select dial gauge, then
Swing rotary handle 9, rotating disk 19 is with fixed seat 18, rotation seat 10, support 17, measuring instrumentss 11 and overall turn of actuator 13
Dynamic, centre of gyration gauge head 14 rotates along universal joint raceway groove, sees that percentage list index fluctuation direction slowly adjusts height rotation adjustment
Switch 6, height rotation adjustment switch 6 rotate the upper-lower height adjustment of control connecting seat 22, until the fluctuation of percentage list index exists
Center principle is found by swinging revolution within 0.01mm, determines universal joint raceway groove centre of gyration position (the B points position shown in Fig. 5
Put), digital display electronic slide calliper rule zero.Centre of gyration gauge head 14 is adjusted to the position with universal joint Internal Spherical Surface inwall stroke 1-2mm again
Put, swing rotary handle 9, height rotation adjustment switch 6 rotates the upper-lower height adjustment of control connecting seat 22, until percentage list index
Fluctuation finds universal joint Internal Spherical Surface centre of gyration position (the A points position shown in Fig. 5) within 0.01mm by swinging revolution, number
The reading that aobvious electronic caliper is shown is the centre-to-centre spacing size of universal joint standard.
The universal joint product for needing to measure is found into two centres of gyration by above step again, draws product center carpenters square
Very little, product center carpenters square cun subtracts each other with universal joint standard centre-to-centre spacing size can draw error amount.
Centre-to-centre spacing size is distance of the A points to two points of B points, and A points are that (raceway groove can also be called for the central point of universal joint raceway groove
Alley), B points are the central points of universal joint Internal Spherical Surface, and the broken circle that D is represented is universal joint Internal Spherical Surface, as shown in figure 5, A-B away from
From be alley center to a distance from Internal Spherical Surface center (assuming that distance is E), because the kit of the universal joint also has a center
Away from that is, the spherical outside surface center of kit is to alley distance (assuming that distance is F), and in theory during E=F, universal joint could be such as axle
Hold and equally rotate, if E is not equal to F, ball rail just can not combine a complete positive round, and universal joint will turn motionless or clamping stagnation.
The utility model more can accurately measure the centre of gyration of universal joint away from can be very good control universal joint
Product quality, reduce the defect rate to dispatch from the factory；Reading is shown by digimatic calipers, more convenient.This practicality also has structure
Simply, the advantages that comfortable, low manufacture cost easy to use.
