The utility model belongs to universal machine and field of plastic machinery, relates to the inner diameter measurement of longer straight inner hole part or equipment, especially a kind of diameter of bore continuous coverage pick-up unit that can be used for charging barrel of plastic extruder.
Background technology
At present, following two kinds are had to the testing tool of some deep-hole parts or equipment hole size:
1. use dial bore gage to detect, the shortcoming of this instrument is: often detect a size, just needs a manually record size, and accurately can not draw the depth data of detected position from this size of record.If when needing the diameter data of multiple diverse location in measured hole, need repetitive measurement and manual record, elapsed time is long, simultaneously this testing tool fathom restricted, the depth capacity that this type of conventional on the market at present instrument can be measured is usual all in 1 meter.
2. use vernier caliper to detect, the shortcoming of this instrument is: the internal diameter size that can only detect part or equipment opening end face, the size of inside, hole can not be detected.Also be need frontier inspection to survey limit hand-kept data simultaneously.
For the detection of equipment endoporus, the cylinder bore size detection on extruder or injection machine production line:
Extruder or injection machine cylindrical shell are all generally assembled by a few joint or the short cylindrical shell of tens joints, then are assembled into the production line of an applicable production technology further, and the length of General Production Lines has several meters even more than ten meters.Then in inner barrel, screw to convey materials is installed, when after use a period of time, needs to do abrasion detection to the hole size of cylindrical shell.If use existing testing tool, need to disassemble often saving cylindrical shell, then use dial bore gage or vernier caliper to detect each endoporus abrasion size saving cylindrical shell and hand-kept, detect a production line (comprise and removing and installing) so general about needs 1-2 consuming time days.
In sum, all there is same problem in two kinds of main testing tools on the market at present:
1. the degree of depth detecting endoporus is restricted;
2. when detecting, need manual record data;
3. detecting depth location corresponding to diameter data can not Measurement accuracy;

Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of can the pick-up unit of continuous coverage deep hole internal diameter, comprise guide wheel 4, measuring sonde 5 and laser range sensor 2, described measuring sonde comprises housing 12, inductosyn 13 and fixed leg 14, in housing, by fixed leg radial symmetry, multiple inductosyn is installed, or organizes inductosyn in the axial parallel installation of fixed leg more.Install two guide wheels in the outer symmetria bilateralis of housing, described inductosyn is by data acquisition unit and computing machine 1 connecting communication, and laser range sensor is by RS232 or RS485 interface and computing machine connecting communication.
Make two minor axis 11, two minor axises in the axis two middle side part symmetries of fixed leg and stretch out housing, be shaped with the minor axis hole coordinated with minor axis at the end face of guide wheel, by fastening bolt 10, they are fixed in the minor axis hole of the minor axis insertion guide wheel of fixed leg.
Described guide wheel comprises cross erecting frame 9, pulley 8, wheel shaft 15 and spring 17, four races are shaped with in outer face, the corner radial symmetry of cross erecting frame, in race, pulley is installed, in the both sides of each race, equal symmetry is shaped with two spring mounting holes, coaxial mounting spring in spring mounting hole, runs through and vertically with race and spring mounting hole is shaped with an axis hole 16, plug-in mounting wheel shaft in axis hole, wheel shaft inserts in the center pit of pulley simultaneously, and plane is made at two positions of wheel shaft and spring contact.Described axis hole is strip hole, and wheel shaft can move in the length range of axis hole.
The installation method of this guide wheel is: first in spring mounting hole, insert spring, then insert pulley in race, and finally inserted from axis hole by wheel shaft and be enclosed within the center pit of pulley simultaneously, two planes of wheel shaft are just to the end face of spring.After such installation, spring is in compression stress, wheel shaft by the spring supporting on both sides, pulley can along the telescopic moving in the length range of axis hole of the center line of cross erecting frame, and then realize also making pulley still fit closely with endoporus inwall when endoporus changes greatly, also achieve simultaneously and move freely in the axis of endoporus.
Described inductosyn is contactlessly measure displacement transducer, and be arranged on fixed leg in the mode of radial symmetry, the arrangement of inductosyn can be mounted to Fig. 4 or Fig. 5 pattern according to the actual requirements.Simultaneously also according to actual conditions, one picture group 4 pattern or installation diagram 5 pattern simultaneously can be installed respectively at the two ends of fixed leg simultaneously, the precision stability of measurement can be improved.
The principle that this inductosyn measures endoporus is: when measuring sonde and guide wheel installation are placed in endoporus to be measured, inductive probe can sense the distance between metal inner surface and inductive probe, and the so final diameter measured is exactly the basis distance that the distance of reaction of two sensors of both sides on centerline adds the installation of upper sensor.
