The purpose of invention:
The objective of the invention is the structure of existing moulding-sand property on-line measuring device is made improvements,, adopt more simple, components and parts and mechanism reliably in conjunction with the concrete condition of Foundry Production, make that whole on-line measuring device is simple in structure, the location accurately, detection reliably.
Technical scheme:
The moulding-sand property on-line measuring device of the present invention's design comprises long stroke cylinder, compaction cylinder, ejects cylinder, clears up cylinder, rotary cylinder, gets sand hopper, main shaft, displacement transducer, headgear and turntable positioning mechanism.Headgear is made up of flywheel, reversed column and dial, and reversed column is fixed on the outer of dial, flywheel and dial and main shaft, the coaxial installation of rotary cylinder.Turntable positioning mechanism comprises block, locating piece and electromagnet, totally four of blocks, the equidistant rotating disk circumferential edge that is fixed on is along the below, and electromagnet is fixed in below, top board edge, and locating piece and electromagnet link, during energising, electromagnet picks up locating piece, and this moment, rotating disk can freely rotate, during outage, locating piece stretches out, with the control rotating disk anglec of rotation.
Beneficial effect:
The moulding-sand property on-line measuring device of the present invention's design, owing to adopted the type of drive that cooperates with flywheel mechanism by rotary cylinder, make simple in structurely, rotating disk is located the mode that the employing electromagnet cooperates with block, prevented that rotating disk block and locating piece from bumping the bounce-back when brushing lightly, thereby guaranteed bearing accuracy.

Embodiment:
Below in conjunction with accompanying drawing, introduce content of the present invention in detail with embodiment.
Among Fig. 3～Fig. 6, the 7th, long stroke cylinder, the 8th, sand hopper, the 9th, compaction cylinder, straight 0 is to eject cylinder, the 11st, the cleaning cylinder, the 12nd, get sand hopper, the 13rd, top board, the 14th, rotating disk, the 15th, be in the test specimen tube of first station, the 16th, block plate, the 17th, intermediate plate, the 18th, base plate, the 19th, send sand belt, the 20th, be in the test specimen tube of second station, the 21st, displacement transducer I, the 22nd, pressure head, the 23rd, electromagnet, the 24th, block, the 25th, shear cylinder, the 26th, displacement transducer II, the 27th, rotary cylinder, the 28th, locating piece, the 29th, main shaft, the 30th, flywheel, the 31st, dial, the 32nd, reversed column, the 33rd, be in the 4th station test specimen tube, the 34th, be in the test specimen tube of the 3rd station, the 35th, the flywheel outer rim, the 36th, return sand hopper, the 37th, permanent magnet.
The function of four stations is respectively:
I one extracts molding sand and adds test specimen tube from belt;
II one consolidation sand sample is also surveyed compact rate of molding;
III one ejects sand sample 15MM and surveys shear resistance and deformation limit;
IV one discloses sand sample, cleaning sample tube.
Automatically controlled-pneumatic mechanism is adopted in main action, detects performance and carries out collection, storage and the processing of data by computing machine, can adapt to the abominable working environment of casting department, acquisition interval is the fastest to reach 10 seconds, can reflect in time that moulding-sand property changes, the reliability height, easy to maintenance.Its course of work is as follows:
Station I: long stroke cylinder (7) descends, and drives to get sand hopper (12) sand sampling from the belt, and long then stroke cylinder (7) lifting is got sand hopper to the top, pour sand sample into sand hopper (8), fall into test specimen tube (15) again, in rotation process, scrape the molding sand at dry sample tube (15) top;
Station II: compaction cylinder (9) drive pressure head (22) presses down the molding sand in the test specimen tube (20), detects the compacting distance by displacement transducer I (21), and machine is calculated compact rate of molding as calculated:
Station III: eject cylinder (10) and will from test specimen tube (34), eject 15mm at the sand sample after the compacting of II station, by shearing cylinder (25) sand sample is sheared then, shear pressure is by determination of pressure sensor and output, simultaneously measure deformation limit, signal input Computer Processing by displacement transducer II (26);
Station IV: cleaning cylinder (11) will have been surveyed the sand sample of shear resistance and deformation limit and disclose from test specimen tube (33), and clear up sample tube inside simultaneously, and the sand sample of disclosing is fallen on the belt through returning sand hopper (36);
More than the action of four stations carry out simultaneously, so per 10～15 seconds (making by oneself) rotates 90 °,, works continuously the online detection of realization molding sand can detect one group of data in per 10～15 seconds.
Embodiments of the invention have designed special-purpose dial rotation mechanism and turntable positioning mechanism, its gear train is: adopt 90 ° of rotary cylinders (27), stir flywheel outer rim (35 by the reversed column (32) on the dial (31), driving main shaft (29) by flywheel (30) rotates, as shown in Figure 5, thus rotating disk (14) is rotated.For making rotating disk intermittently rotate 90 ° forward exactly, adopt detent mechanism, promptly installing four blocks (24) on rotating disk are fixed an electromagnet (23) and locating piece (28) on top board (13), moving 90 ° of rotating disk (14) revolution, electromagnet (23) is even locating piece (28) moves down, block block (24), the bounce-back when preventing to collide is equipped with permanent magnet (37) in side, locating piece top, accurately, see Fig. 6 to guarantee the location.
