Description

High-precision sensor protection device
Technical field
The present invention relates to the installation and protection of sensor in circle pulsation measurement equipment, more particularly to circle pulsation measurement equipment.
Background technology
On the periphery of part, certain section of periphery is caused to connect due to punching or opening up groove, technology groove etc. Continuous, this section of periphery is referred to as discontinuous circular surfaces.In the measurement of the circle bounce of discontinuous circular surfaces, if making the shifting of sensor Dynamic measuring probe takes the directly point way of contact with discontinuous circular surfaces, then due to hole or the groove opened up, technology groove etc. Influence, not only result in larger measurement error or measurement failure, and easily cause expensive sensor colliding With being damaged in vibrations.
The content of the invention
It is an object of the invention to solve the accurate measurement of circle bounce of the discontinuous circular surfaces of part and the protection of sensor Problem, and provide high-precision sensor protection device.
For the above-mentioned purpose, the present invention adopts the following technical scheme that.
High-precision sensor protection device, it is characterised in that:
The tubular shell being connected on adjustable support, the centre bore of tubular shell are arranged to three rank stepped holes, upper step Hole connects hollow cutting ferrule, cutting ferrule (4) endoporus socket sensor;
Lower section stepped hole connection is mobile foxy, and mobile foxy one end sets the cap coordinated with lower section stepped hole step surface, The mobile foxy other end sets contact foxy, and the arc surface coordinated with Cylindrical Surfaces Contact to be detected is set on contact slippery fellow;
Connecting spring between mobile foxy and cutting ferrule;The traverse measurement probe of sensor contacts with mobile slippery fellow.
According to such scheme, there are following further technical schemes:
Holding screw is connected in the side wall in upper step hole, holding screw compresses cutting ferrule, cutting ferrule clamping sensor.
Guide groove is set on mobile slippery fellow;Guider screw is connected in the stepped hole side wall of lower section, guider screw is matched somebody with somebody with guide groove Close and slide.
After adopting the above technical scheme, the traverse measurement probe for avoiding sensor is directly put with discontinuous circular surfaces and connect Touch so that motion and the special delivery of power can be effectively reduced pit or opened up in discontinuous circular surfaces with the transmission of steady and continuous The measurement on circle bounce such as hole, technology groove influences, and effectively protects sensor.
Brief description of the drawings
Fig. 1 is the front view of the present invention;
Fig. 2 is the A-A sectional views of the present invention.
Embodiment
High-precision sensor protection device, as shown in Figures 1 and 2, including universal pillar 1, universal pillar 1 pass through adjustable armful 2a adjustably connecting cantilever 2 are bound round, the one end of cantilever 2 is fixedly connected by fixed anchor ear 2b with cylindrical tube shape housing 3, tubular shell The centre bore of body 3 is arranged to three rank step cutting pattern hole 3a, and set screw hole 3b, lower section step are set in the side wall in upper step hole Rotation stop hole 3c is set in the side wall in hole, and rotation stop hole 3c is screwed hole.Hollow cylinder cutting ferrule 4, cutting ferrule 4 are assembled in upper step hole Endoporus is socketed sensor 5.Assembling holding screw 6 in set screw hole 3b, holding screw 6 compress cutting ferrule 4, the clamping of cutting ferrule 4 sensing Device 5.
Assembling cylinder movement slippery fellow 8 in the stepped hole of lower section, 8 one end of mobile slippery fellow set cylindrical cap 8b, cap 8b with Lower section stepped hole step surface coordinates, and 8 other ends of mobile slippery fellow set cuboid to contact foxy 8c, and it is in movement to contact foxy 8c One end chamfered edge of slippery fellow 8 and be made, contact the arc surface 8d that foxy 8c end sets and Cylindrical Surfaces Contact to be detected coordinate, circular arc Face 8d nominal diameter is equal or slightly larger than the nominal diameter on the face of cylinder to be detected;Set in the axial direction on mobile slippery fellow 8 Strip rotation stop groove 8a.Assembling rotation stop part 9 in the 3c of rotation stop hole, rotation stop part 9 preferentially selects holding screw, rotation stop part 9 and rotation stop groove 8a coordinates to mobile foxy 8 circumferential rotation stops.
Connecting spring 7 between mobile slippery fellow 8 and cutting ferrule 4, spring 7 are placed in middle bench hole.The traverse measurement of sensor 5 Probe 5a and mobile foxy 8 end contacts.
Operation principle is summarized
As shown in Figures 1 and 2, workpiece for measurement 10 is installed in the live spindle 11 of testing stand, adjust universal pillar 1 and Cantilever 2 is to appropriate location so that the arc surface 8d on mobile slippery fellow 8 connects with the face of cylinder forming face to be measured on workpiece for measurement 10 Touch, and under the elastic force effect of spring 7, mobile slippery fellow 8 is in contact condition all the time with workpiece for measurement 10.
Firing test motor drives live spindle 11 to rotate, and workpiece for measurement 10 is also with rotation.
In rotary course, with the change of the profile of workpiece for measurement 10, mobile slippery fellow 8 can transport with the change of profile Dynamic, so as to which the traverse measurement probe 5a on sensor 5 can also move with the motion of mobile slippery fellow 8, so, sensor 5 is just Collect the data of the profile of workpiece for measurement 10.
In rotary course, because the contact between mobile slippery fellow 8 and workpiece for measurement 10 is that low minor face contacts, therefore work to be measured The technology groove 10a opened up on part 10 does not interfere with the data that sensor 5 collects, while does not interfere with mobile slippery fellow 8 with treating yet The power surveyed between workpiece 10 and the transmission of motion.
In overall process, rotation stop part 9 and rotation stop groove 8a coordinates, and producing circumferential rotation stop to mobile slippery fellow 8 acts on.In fact, Because mobile slippery fellow 8 and workpiece for measurement 10 are in contact condition all the time, and mobile foxy 8 contacts with workpiece for measurement 10 belong to Circular arc camber contacts, so this kind of way of contact can also play circumferential rotation stop effect to mobile slippery fellow 8 in measurement process, still Mobile foxy 8 when can not be to disengaging play circumferential rotation stop effect.
