Description
Technical field
The invention belongs to oil and belong to the dynamic balance test technical field of oil press, relate in particular to a kind of for measuring the device with the horizontality of correction oil press master cylinder.
Background technology
Oil press in process of production, the vertical movement situation of master cylinder directly affects the quality of compacted products, especially suppress the 9000 ton large-scale wheel forge press that wheel is used, the dynamic horizontal degree of upper and lower two planes of master cylinder is inconsistent, the wheel rim height circumferential asymmetry that directly affects wheel is even, causes qualification rate low, and the weight that feeds intake increases, lumber recovery is low, and production cost is high.The domestic and international dynamic monitoring for master cylinder level at present still belongs to blank, because be subject to the impact of the severe rolling factors such as environment, all do not have good way to complete dynamic monitoring, can only in follow-up rolling process, find after product defects, then adjust the level of master cylinder.Therefore, thirst for having a kind of master cylinder levelness on-Line Monitor Device, solve a difficult problem for on-line monitoring.
Summary of the invention
The defect existing in order to overcome prior art, the object of this invention is to provide a kind of large-sized hydraulic press master cylinder levelness on-Line Monitor Device, finds in time the master cylinder tilt problem in the operation of rolling, improves the qualification rate of rolled products, avoids producing waste product in enormous quantities.
Large-sized hydraulic press master cylinder levelness on-Line Monitor Device, comprises master cylinder, is characterized in that master cylinder four sides at least arrange the one-sided position monitoring mechanism of the above master cylinder of three covers; The one-sided position monitoring mechanism of described master cylinder is connected and composed by pipe support, displacement transducer, magnet ring stock and base; Orienting sleeve is established in described pipe support lower end, and through hole is established in upper end, is bolted on upper beam, and pipe support is sleeved on the measuring staff of displacement transducer; On described magnet ring stock, establish magnet ring, magnet ring stock one end is sleeved on the measuring staff of displacement transducer, and the other end is connected with master cylinder, and magnet ring stock moves up and down with master cylinder, is shown the movement position of master cylinder by displacement transducer; The installation threaded engagement of threaded hole and measuring staff is established in described base upper end, and through hole is established in base lower end, is bolted on heel post; Through hole center on the measuring staff of described sensor, pipe support, orienting sleeve, base coexists on a perpendicular line.During use, the one-sided position monitoring mechanism of master cylinder is contained on the Si Ge side, all directions of master cylinder, master cylinder moves up and down, and drives magnet ring motion, by displacement transducer, its numerical value is outputed to computer screen, by contrasting the sensor values of 4, just can measure master cylinder whether in same level.
The present invention further improves, and described pipe support is tubular, and pipe support is established screw, and it is tubular that orienting sleeve is, and is bolted in pipe support, stablizes the measuring staff with safeguard bit displacement sensor; Boss is established in pipe support upper end, and boss is established through hole, is bolted on upper beam.
The present invention further improves, and on described magnet ring stock, establishes threaded hole, and on magnet ring pad, magnetism isolating spacer circle is fixed on magnet ring stock by screw, and magnet ring stock is sleeved on measuring staff, and the magnet ring stock other end is connected with master cylinder, and the displacement signal of master cylinder passes to sensor.
The present invention further improves, and described base takes the shape of the letter U, and upper limb is established threaded hole, and with the threaded engagement that establish measuring staff lower end, turn screw thread is fixed.
Compared with prior art, advantage is novel, simple in structure, compact; Measure in time, accurately, reliably, realization is monitored in real time to the levelness of master cylinder, find in time the master cylinder tilt problem in the operation of rolling, reduce wheel eccentricities and rim face crooked, avoid a large amount of waste products that produce because of master cylinder levelness deviation, improve product percent of pass, improve product quality, guarantee to produce and carry out smoothly.
