The operation principle of the present invention：Front and rear adjective-centre structure is connected by bolt with laser detection system, rear adjective-centre structure profit
Spring and sphenoid are positioned with the polished rod of laser mount.Sphenoid cooperates with rolling steel ball, tapered shaft, leverage,
According to hole wall centering, ensure that post-positioning device axis overlaps with axially bored line.Two springs act power to sphenoid, make wedge
Block has the trend that holding moves right.Leverage are extruded by voussoir inclined-plane, radially outward side slip, keep rolling steel ball
It is in close contact with hole wall, and then realizes certralizing ability.Preceding adjective-centre structure is positioned using nut, spring, slider-crank mechanism.
Nut screws in extruding, and spring is compressed and promotes sliding block, and connecting rod around hinge rotates, and the top of three connecting rods contacts simultaneously with hole wall
And certain contact force is maintained, realize centering.Contact is adjusted indirectly by nut precession amount.The light beam warp of laser generator
Too small axicon lens is irradiated on hole wall, and then diffusing reflection is to receiver.The displacement of receiver record hot spot is with the time or along axis
The change of direction displacement.Photoelectric encoder records the rotating speed of motor, records the displacement of copper cash, i.e. detector indirectly along taper hole axis
Displacement change with time.Two groups of data constituting-functionses relations, are recorded in computer, bellmouth are obtained by data analysis
Taper, length, geometric data and the relevant parameter such as roughness.The present invention is suitable for appropriate diameter, the hole of different tapers, and protects
Card device axis relative to axially bored line registration.
During work, motor driving drum and copper cash, traction detection means move along a straight line with the axis in hole.Adjective-centre structure afterwards
Nut pretension spring is produced pre compressed magnitude, the spring pressure of formation promotes connecting rod-slide block mechanism action, and three connecting rods are around hinge
Chain rotates simultaneously and connecting rod end keeps certain contact force with hole wall, is realized and arrived using three points centering and force balance principle
The purpose that detection means central shaft overlaps with deep hole axis.In the course of work, when aperture becomes big, spring promotes sliding block towards fixation
Hinge, move along axis, drive long connecting rod to open a business simultaneously and keep contacting with hole wall, to be adapted to the increase in aperture；When aperture diminishes
When, long connecting rod rotates in the case where conic hole wall pressure is compeled around fixed hinge, promotes sliding block and compression spring.Axial arranged spring is realized
The trans-utilization of potential energy and the steady contact power with hole wall.The acting force of the spring of preceding centring means promotes voussoir to be transported along axis
It is dynamic, leverage is radially acted by voussoir inclined-plane, to keep the contact between rolling steel ball and hole wall.The change in aperture
Making the straight-line displacement of sliding block and tapered shaft generation along voussoir inclined-plane, extruding sphenoid, installation axle produce movement tendency vertically,
Change amount of spring compression.Photelectric receiver of the present invention receives the light that generating laser is sent, for detecting hole in piece part
Circularity, taper change relative to the micro-displacement of theoretical axis, during work, if the actual pattern in hole only has relative to theoretical axis
Micro-displacement changes, and hot spot produces a micro change on photelectric receiver, and the variable is exactly micro-displacement change, reflects the position
The deviation of lower pore radius relative ideal radius, and then calculate circularity.
Photelectric receiver of the present invention receives the light that generating laser is sent, and can detect the real radius of hole in piece part
Relative to the micro change of principal radii, during work, if real radius only has micro change relative to principal radii, hot spot is in light
On electric receiver produce a variation, according to reflection amplification principle, using function the variation can be converted to radius or
The micro change of person hole pattern.
Motor of the present invention is connected to computer with photoelectric encoder, realizes the data storage of photoelectric encoder and turns
Change.The data of photelectric receiver are imported into computer after the completion of experiment, corresponding with the data of photoelectric sensor, construct aperture
And function of the other parameters on axial location.
Photoemitter of the present invention, size axicon lens, photelectric receiver are on the outside of mounting ring, axially disposed, edge
Circumferentially three groups of optoelectronic transceiver devices, it is ensured that measurement accuracy.
Rolling steel ball of the present invention, leverage, tapered shaft coordinate sphenoid form before adjective-centre structure.Rolling steel ball and hole
Wall is advantageous to reduce the frictional force in advancing, improves accuracy of detection in being in rolling contact.Leverage possess one to the hole of different tapers
Determine adaptability.On the polished rod for the thin portion that spring II, spring III are arranged on laser mount.Sphenoid be arranged on two springs it
Between, balanced by pressure and the spring thrust of tapered shaft.Tapered shaft passes to rolling steel ball under ramp effect and holds out against hole wall.Roll
The lever balance effect that steel ball is formed by tapered shaft hinged support, it is adapted to the taper hole of different tapers.Three tapered shafts 17
Simultaneously by the radial thrust from spring and sphenoid inclined-plane, good contact is kept with hole wall, realize front retainer center line with
Axially bored line overlaps.Simultaneously because steel ball is in that point contacts with hole wall, and its rollability so that the friction in steel ball and hole is smaller.For
Sphenoid rotation in sleeve is prevented, designs anti-rotation pin, in case tapered shaft rotates with sphenoid and damages device.
The installation axle of adjective-centre structure is connected by screw with laser mount after of the present invention.Nut thread is connected to peace
Dress axle simultaneously screws in, and adjusts the stroke of spring.Under spring action, sliding block slides in the axial direction, changes two connecting rods
The spacing of respective hinge, rotates connecting rod around hinge.The connecting rod top of three connection rod sets and the hole inwall of deep-hole parts connect all the time
Touch, according to three-point circle principle, centering machine center line overlaps with deep hole axis after realization.
Detection means described in invention drives, under copper cash draw in motor, is fed along the axis in hole.Institute
The copper cash stated is connected on the polished rod of laser positioning part end around fixed pulley, so as to which motor power is passed into detection means,
Fixed pulley changes copper cash transmission direction, makes motor installation adaptability stronger.
The present invention integrates mechanical, electrical, light, and using laser technology and photoelectric sensor, structure is based on spring-voussoir system
Device, simple in construction, cost is cheap, easy to use, it is possible to achieve whole dynamic detection deep hole diameter with axial location change
Change, extrapolate cylindricity, taper, the means for making to carry out circularity to deep-hole parts, taper detects tend to height and refined, and are deep hole detections
Technical important breakthrough.
