The specific embodiment
Embodiment; As depicted in figs. 1 and 2, a kind of roll grinding machine high precision full-automatic on-line measurement system, comprise measuring appliance, measuring appliance comprises electromagnetism-gas-driving valve 1, measuring stick 2, extension spring 3 (starting force indentation left as shown in Figure 1), short lines grating chi 4, support 5 and gage outfit 6, short lines grating chi is fixed in the support, short lines grating chi carries air cavity 13 and piston 12, described piston cooperation places described air cavity, the one side of piston (being top among Fig. 4) is provided with piston rod 121, described piston rod part passes air cavity, short grating gauge head is located at piston rod part, piston another side (being following among Fig. 4) constitutes seal cavity with air cavity, electromagnetism-gas-driving valve communicates in described seal cavity, piston maintains in air cavity away from the thrust of its seal cavity direction and (is thrust upwards among Fig. 4, among Fig. 1 thrust left), gage outfit 6 is located at the lower end of measuring stick 2, the measuring stick intermediate point is articulated in the support, the extension spring 3 one ends rack body that is connected, the be connected top of measuring stick hinged place of the extension spring other end, also be provided with a drag hook 7 in the measuring appliance, drag hook one end is fixed in the measuring stick upper end, the drag hook other end is provided with an opening 10 (this opening internal diameter is less than this weak point grating gauge head external diameter) over against short grating gauge head, the neck of short grating gauge head freely is arranged in (drag hook trace activity displacement relatively) in this drag hook other end opening, lack grating gauge head stop in this drag hook opening inner edge in case deviate from.
Drag hook 7 one ends are fitted and are fixed in the measuring stick upper end.
The thrust structure that piston maintains in air cavity away from its seal cavity direction is: be provided with an elastic device 14, elastic device one end resilient abutment piston another side (being following among Fig. 4), the seal cavity inner bottom surface (in Fig. 4 be air cavity bottom surface) of the elastic device other end in this air cavity, seal cavity bottom surface (being the air cavity bottom surface among Fig. 4) is provided with air inlet 16.
Electromagnetism-gas-driving valve communicates by the seal cavity of this air inlet with short lines grating chi air cavity.
The short lines grating chi of the piston of band described in this example is an outsourcing piece, and this example of concrete structure no longer describes in detail.
Operation principle of the present invention is: (being contact 8 installation portions) adds the upper end that a drag hook 7 will be lacked 9 pullings of grating gauge head and drag hook 7 applyings will be fixed on measuring stick 2 in measuring stick 2 upper ends in employing.See Fig. 1, Fig. 2 and Fig. 3: when gage outfit 6 past moving right, by measuring stick 2 drive contacts 8 past moving left, at this moment the starting force of elastic device 14 piston 12 (see figure 4)s of boosting in the short lines grating chi 4, make short grating gauge head 9 follow contact 8 and carry out servo-actuated (to moving to left, see Fig. 1), make the short grating gauge head 9 be located at these piston rod 121 upper ends can keep in touch with contact 8 all the time during (among Fig. 1 for left) propelling forward like this; When some in particular cases (refers to damage or the wear measurement head) gage outfit 6 is broken away from measure roll surfaces the time, then want gage outfit 6 to move to left (shown in Fig. 1), at this moment the electromagnetism-gas-driving valve 1 that is loaded on the support 5 is opened the generation negative pressure, make piston 12 in short lines grating chi 4 air cavitys 13 form backward the suction of (among Fig. 4 for downwards), thereby overcome the thrust of elastic device 14, making piston 12 drive the short grating gauge head of being located on the piston rod 121 9 hauls measuring stick 2 by drag hook 7 and carries out servo-actuated (contact 8 is moved right), thereby gage outfit 9 is broken away from measure roll surface, when will arriving the setting measurement roll surface again, gage outfit 9 (also do not touch roll surface), electromagnetism-gas-driving valve 1 is closed, gage outfit 9 move to right (shown in Fig. 1) arrive the setting measurement roll surface and measure, when open and to set according to the roll crown that will measure in advance as for electromagnetism-gas-driving valve 1, as measuring roll tail or low spot when gage outfit 9 will remeasure the time, gage outfit 9 collides roll easily and damages, just need open electromagnetism-gas-driving valve 1 and produce negative pressure, and when measuring roll crown, always close electromagnetism-gas-driving valve 1, this example of detailed process no longer describes in detail.Therefore this example has not only solved the servo-actuated problem of measuring stick 2, has avoided the wearing and tearing of gage outfit 6 in practical operation and measuring stick to be wound again better, makes measuring appliance can carry out high-precision full-automatic on-line measurement.
This measuring appliance can cooperate following gage beam to use, and on-line Full like this detection better effects if is as Fig. 5.
See Fig. 5, Fig. 6 and Fig. 7: the mobile employing ball screw transmission of gage beam 36, promptly the servomotor 22 with decelerator 23 is connected with ball wire bar pair 25 by shaft joint 24, again by being loaded on advancing or retreating of nut seat 26 driving gage beams 36 on the ball wire bar pair 25.Its position is detected and is fed back to system host and handle (prior art) by being loaded on long grating chi 38 on the gage beam 36.The drive gap and the backlass of selected ball wire bar pair 25 minimum (being 0.018mm).So can cooperate with long grating chi 38 on the gage beam 36 by the round grating chi 39 of servomotor 22 gage beam 36 mobile carried out closed-loop control (prior art), in addition, the line slideway 35 of the guide rail that gage beam 36 moves for using, import high accuracy line slideway 35 has effectively been guaranteed stationarity, kinematic accuracy and the rigidity that gage beam 36 moves, and the assurance of strong basic precision is provided for the on-line measurement of system.
