Detailed description of the invention
This device have employed the addition principle of laser ranging, arranges the first laser instrument 3 and the second laser 4 of two reversely measurements point-blank during making, and measurement data can be transmitted to industrial computer 11.Its fundamental measurement principle is as shown in Figure 3.In figure, the first laser instrument 3 and second laser 4 are arranged dorsad with constant spacing B3, and are in the diameter line of pipe die 5 from the first laser instrument 3 and second laser 41 laser emitting of popping one's head in.During work, the beam of laser that the probe 1 of second laser 4 emits is radiated at the inwall below pipe die, on the C MOS chip of the receiver 2 again returning to second laser 4 that diffuses of pipe die inwall, by to the position analysis of hot spot on C MOS chip and calculating, second laser 4 can be obtained to the actual range B1 of inwall below pipe die 5；In like manner can obtain the first laser instrument 3 and arrive distance B2 of symmetrical upper inner wall.Spacing B3 of the first laser instrument 3 and second laser 4 arrives, plus two probes 1, the internal diameter size D that distance B1 of measured object upper and lower surface, B2 i.e. can get pipe die.
Two C-MOS chips can be in data transmission to industrial computer 11, and industrial computer 11 calculates pipe die 5 internal diameter size and tapering, and can draw inside radius curve according to result of calculation, and all of data are finally storable on industrial computer 11 hard disk, it is simple to subsequent quality is reviewed.
As depicted in figs. 1 and 2, the device of measurement pipe die internal diameter of the present utility model and tapering includes: the first laser instrument 3, second laser 4, measurement support 6, standard cushion block 7, dolly 8, pull bar 10 and industrial computer 11, it is respectively provided with probe 1 and receiver 2 in first laser instrument 3 and second laser 4, second laser 4 is fixed on dolly 8, first laser instrument 3 is fixed on measurement support 6, standard cushion block 7 is detachably combined on dolly 8, size according to pipe die 5 diameter, the height of standard cushion block 7 is adjustable, in the most extreme case, standard cushion block 7 can be cancelled, it is placed on folded for the first laser instrument 3 on dolly 8.Measurement support 6 is contained on standard cushion block 7, and vertically upward, the probe 1 in second laser 4 is vertically downward for the probe 1 in the first laser instrument 3, they are installed on same straight line, receiver 2 is C-MOS chip, and this C-MOS chip is connected with industrial computer 11 respectively, in the side of dolly 8 equipped with pull bar 10.Dolly 8 is attached separately on the symmetrical position of dolly 8 equipped with 9,4 wheels 9 of 4 wheels, 1 is at the diametrical position of pipe die 5 to ensure to pop one's head in.
During measurement, first have to adjust the distance between the probe 1 of two laser instruments 3 and 4 according to actual conditions, and input this value in industrial computer 11；Then can be slowly pushed into from pipe die 5 female end by 10 measurement apparatus of pull bar, arrange spacing at initiating terminal and end end, can stop in time after probe 1 puts in place；When described measurement apparatus is positioned at a certain position, the probe 1 of the first laser instrument 3 upwards launches laser, laser is back on the receiver 2 of C MOS chip of the first laser instrument 3 at pipe die 5 upper wall after diffusing reflection, the position of hot spot can be analyzed by described C MOS chip, can show that described laser probe, to the distance above pipe die 5 inwall, and transmits result of calculation to industrial computer 11；C MOS chip in like manner lower section measurement second laser 4 can be by the Distance Transmission below this measuring probe 1 to pipe die 5 inwall to industrial computer 11；With being slowly pushed into of pull bar 10, the internal diameter numerical value of whole pipe die 5 length can be measured；Industrial computer 11 can carry out record to these numerical value, obtains the internal diameter numerical value of all positions, and draws inside radius curve and tapering curve, is saved in all data on hard disk simultaneously and is used for later stage size quality and reviews；
When measuring small-bore pipe die 5, can place overlapping for two laser instruments, due to two laser instruments not on same diameter line, record two groups of data can be entered line misregistration and be added, to reduce error by industrial computer 11；In the measurements when bore and heavy caliber pipe die, as long as installing corresponding standard cushion block additional in measurement support workshop little with measurement.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range sees claim, and in the case of without prejudice to spirit of the present utility model, the utility model can make any type of modification.
