Description
Technical field
The present invention relates to a kind of height detecting device of workpiece, be specifically related to a kind of magnetic floating support assembling height on-line measuring device.
Background technology
Traditional load-bearing bearing is single-piece assembling as bridge steel support, the main contents of factory inspection are the performance test of bearing, and mainly is that Thickness Design and control by each part realizes to control of its height.Because lower to the accuracy requirement of height of support on the bridge, the error of measuring height of support when dispatching from the factory can meet the demands in ± 1～2mm scope.
But for the magnetic flotation line, its linear requirement to track girder is very high, and the difference in height of promptly adjacent two track girders must not surpass 1mm, thus also very high to the requirement for height of the magnetic over draft seat of supporting track beam, require its error control in ± 0.5mm.Prior art to the dispatch from the factory method of inspection of height of magnetic over draft seat is: after bearing assembling is finished, highly measuring the whole height of station place measurement bearing under state of nature on the assembly line, as the height that records and the error between the design height surpass ± 0.5mm, then adjusts in the error range by regulating the bearing elevating mechanism.But because the duty of magnetic over draft seat at the bottom of track girder is to be subjected to track girder deadweight and vehicle-mounted variable amplitude loading effect, and bearing dispatches from the factory and does not highly consider this type of loading, there is the fit-up gap unavoidably, thereby the height when causing with the bearing operate as normal is inconsistent, need increase when causing the scene to adjust line style and consider this influence factor.
Summary of the invention
Purpose of the present invention is to overcome the problem that above-mentioned prior art exists, and provides a kind of and eliminate the fit-up gap, satisfies a kind of magnetic floating support assembling height on-line measuring device of actual working state.
To achieve these goals, the present invention has adopted following technical scheme: a kind of magnetic floating support assembling height on-line measuring device, be arranged on the height detection station of magnetic over draft seat assembly belt, comprise frame, hydraulic jack, pressure transducer and displacement transducer, frame be erected on the streamline and with the streamline cover cap interior, hydraulic jack vertically is installed in the bottom of frame, its piston rod stretches out upward, pressure transducer is connected the upper end of piston rod, displacement transducer is connected the side of hydraulic jack, and its carriage release lever links to each other with pressure transducer.
Described frame is four column type frames or two column type frames.
The present invention makes it compared with prior art owing to adopted above technical scheme, has following advantage and characteristics:
1., detect, eliminated the fit-up gap of magnetic over draft seat, reached approaching, thereby made the linear adjustment work of later stage magnetic levitation track girder convenient more with bearing actual working state situation by adopting magnetic floating support assembling height on-line measuring device of the present invention.
2., the magnetic floating support assembling height on-line measuring device is arranged on the former assembly line, thereby guarantee that the height of support Control work carries out on line, do not influence other operations, help the industrialization of magnetic over draft seat and produce.
3., magnetic floating support assembling height on-line measuring device detection method of the present invention is simple, detects accurately and reliably, the height error that can guarantee magnetic over draft seat is within the permissible error scope.
Description of drawings
Fig. 1 is the basic structure synoptic diagram of magnetic floating support assembling height on-line measuring device of the present invention.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, magnetic floating support assembling height on-line measuring device of the present invention is arranged on the height detection station of magnetic over draft seat assembly belt 4, comprises frame 1, hydraulic jack 5, pressure transducer 3 and displacement transducer 6.Frame 1 be erected on the streamline and with streamline 4 cover caps interior, can adopt four column type frames or two column type frames, upper rack is provided with one and is used for the crossbeam of conflicting and to link to each other with magnetic over draft seat.Hydraulic jack 5 vertically is installed in the bottom of frame, and its piston rod stretches out upward, and pressure transducer 3 is connected the upper end of piston rod, and displacement transducer 6 is connected the side of hydraulic jack 5, and its carriage release lever links to each other with pressure transducer 3.
The method step that adopts magnetic floating support assembling height on-line measuring device of the present invention to detect is: when magnetic over draft seat 2 flows to the height detection station, suspend the several seconds at this station, control hydraulic jack 5 side's motion vertically upward this moment, the piston rod for the treatment of hydraulic jack 5 promotes pressure transducer 3 slowly withstand bearing 2 after, exert oneself to about 300kN by pressure transducer 3 Comprehensive Control oil cylinders, the pressurize several seconds, after treating that bearing 2 fit-up gaps are eliminated, be scaled the true altitude H of bearing 2 again by the reading L of displacement transducer 6
1, this moment is the true altitude H of bearing 2 relatively
1Error amount with operational height H | Δ |.
If | Δ |≤0.5mm (true altitude of magnetic over draft seat and the permissible error of operational height), then the height of bearing 2 meets the demands, slowly unload oil cylinder 5 this moment, treat that oil cylinder 5 piston rods retreat to the appropriate location, bearing 2 falls to being back on the streamline 4, assembly belt 4 continues operation, and bearing 2 flows into subsequent processing.
As | Δ |＞0.5mm, then need regulate the height of bearing 2, this moment is with oil cylinder 5 unloadings, treat that oil cylinder 5 piston rods retreat to the appropriate location, bearing 2 falls to being back on the streamline 4, according to error amount | Δ | size, by regulating the height that other structures on the bearing 2 are regulated bearing 2, duplicate measurements bearing 2 height, circulation successively again after having adjusted.Within the permissible error scope, the magnetic over draft seat of letting pass then is to subsequent processing until the error of the true altitude of magnetic over draft seat and operational height.
