Dynamic device is in contact with linear displacement transducer, and the movement of floating installation makes linear displacement transducer record measuring rod relative movement
Displacement, on-line measurement to blind hole depth is completed by PLC operation.
Conceived according to foregoing invention, adopted the following technical solutions:
A kind of hole depth on-line measurement device of depth blind hole, including a measured workpiece and a mounting rack, the measured workpiece
Positioned at the mounting rack left side, on the mounting rack, a guide rail is fixedly mounted, the guide rail front-end and back-end respectively install one
A limited block installs two sliding blocks on the guide rail, a measurement mounting base, the survey is fixedly mounted on described two sliding blocks
Mounting base left end front and back respectively one linear bearing of installation is measured, the interior piece guide rod of installation of slide fit respectively of each linear bearing, two are led
A left link block is fixedly mounted in bar left end, and right end installs a right link block, the left link block and the right link block phase
When can move together in an entirety；Between the left link block and the linear bearing, it is set on each guide rod
A piece spring, so that the left link block has thrust to the left always；Sliding sleeve installs a measurement among the left link block
It is fixedly connected among bar, the measuring rod right end and the measurement mounting base left end, the left link block can be in the measurement
It is moved on bar；A sensor contact block is fixedly mounted in intermediate in the right link block, among the measurement mounting base
A linear displacement transducer is fixedly mounted, the gauge head of the linear displacement transducer withstands on the right side of the sensor contact block
End；A cylinder block is fixedly mounted in the right on the mounting rack, and a pusher cylinder is fixedly mounted on the cylinder block, described to push away
The piston rod of cylinder of taking offence is connect by a floating cylinder connector with the measurement mounting base.
The present invention compared with prior art, has following obvious prominent substantive distinguishing features and remarkable advantage:
The phenomenon that low, low efficiency that the present invention overcomes manual measurement bring measuring speeds, error are big, are unable to on-line measurement, together
When can be directed to different-diameter size and different depth height blind-hole parts on-line measurement, improve the processing efficiency of production line,
And structure is simple, and manufacturing cost is low, and precision is high.
Detailed description of the invention
Fig. 1 is main view of the present invention.
Fig. 2 is top view of the invention.
Fig. 3 is standard component cross-sectional view of the invention.
Specific embodiment
Details are as follows for the preferred embodiment of the present invention combination attached drawing:
Referring to Fig. 1, Fig. 2, a kind of hole depth on-line measurement device of depth blind hole, including a measured workpiece 13 and a mounting rack
1, the measured workpiece 13 is located at 1 left side of mounting rack and a guide rail 14 is fixedly mounted on the mounting rack 1, described to lead
A limited block 12 is respectively installed in 14 front-end and back-end of rail, and two sliding blocks 16, described two sliding blocks 16 are installed on the guide rail 14
A linear bearing 15, Mei Gezhi is respectively installed in one measurement mounting base 4 of upper fixed installation, 4 left end of the measurement mounting base front and back
Spool holds difference slide fit in 15 and installs a guide rod 8, and a left link block 10, right end installation is fixedly mounted in two 8 left ends of guide rod
One right link block 7, the left link block 10 and the right link block 7 are equivalent to an entirety, can move together；The left side
Between link block 10 and the linear bearing 15, a spring 9 is set on each guide rod 8, so that the left link block
10 have thrust to the left always；A piece measuring rod 11,11 right end of measuring rod are installed in the intermediate sliding sleeve of the left link block 10
It is fixedly connected among 4 left end of measurement mounting base, the left link block 10 can move on the measuring rod 11；Institute
A sensor contact block 6 is fixedly mounted in the intermediate of the right link block 7 stated, and is fixedly mounted one among the measurement mounting base 4
A linear displacement transducer 5, the gauge head of the linear displacement transducer 5 withstand on the right end of the sensor contact block 6；The peace
It shelves the right on 1 and a cylinder block 3 is fixedly mounted, a pusher cylinder 2, the promotion gas is fixedly mounted on the cylinder block 3
The piston rod of cylinder 2 is connect by a floating cylinder connector 17 with the measurement mounting base 4.
The working principle of the present embodiment is as follows:
Before the start of the measurement, the linear displacement transducer 5 need to be demarcated with master body C, as shown in figure 3, obtaining
The blind hole hole depth numerical value of standard depth, the measured workpiece 13 is equal to the sum of standard depth, the amount of deflection；When jacking apparatus 18 will
When the measured workpiece 13 is jacked in place, the piston rod of the pusher cylinder 2 stretches out, the measuring rod 11, the left link block
10 and the right link block 7 it is described measurement mounting base 4 drive under move along a straight line to the left, when left 10 left side of link block
When meeting the nozzle end face A of the measured workpiece 13, the left link block 10 is no longer moved, this nozzle end face A is to measure base
Quasi- face, the measuring rod 11 continues to the left under the pusher cylinder 2 effect, when the quilt is encountered in 11 left side of measuring rod
When surveying the blind-hole bottom face B of workpiece 13, the relative shift between the measuring rod 11 and the left link block 10, as relatively
In the departure of standard blind hole depth；The right link block 7 moves simultaneously with the left link block 10, therefore the right link block 7
The movement of the sensor contact block 6 is driven, so that so that the linear displacement transducer 5 is measured relative shift is transferred to PLC
On, the on-line measurement to 13 depth of measured workpiece is realized by the calculating of PLC；When the piston rod of the pusher cylinder 2 contracts
Hui Shi drives the measurement mounting base 4, the measuring rod 11 and linear displacement transducer 5 to lead on the sliding block 16 along described
Rail 14 moves right, and the measuring rod 11 is made to exit the blind hole of measured workpiece 13, and the measured workpiece 13 drops in jacking apparatus 18
Under, complete all processes of the blind hole depth measurement to the measured workpiece 13.
