Description
Technical field
The utility model belongs to field of sensor preparation, particularly relates to a kind of rolling mill screwdown position sensor.
Background technology
--finish rolling pressure leading screw moves up and down, and---working roll meets gap to adjust, and---position sensor detects the gap that its absolute altitude size---Computing---finish rolling pressure motor-driven adjustment working roll needs to finish rolling pressure motor-driven.
In use, due to finish rolling pressure leading screw excesssive gap, concentricity tolerance ensures the factors such as difficult, sensor clamp intensity is low, seal gap design is too small to hot rolling mill finish rolling depressing position sensor.Successively occur that the fault such as often to be thrown off at by clamp fracture, main stroke lever locking, connecting clamp place.Again because position sensor body is carbon steel structure part, in use, often tie condensed water by pressure temperature difference influence and depress the corrosion of oil gas, steam, causing position sensor each portion components and parts and structural member corrosion to come off, impel connecting portion to wear and tear.Make finish rolling depress inlet sensor equipment fault to take place frequently, serious threat administration measure runs and product quality.Position sensor operation principle:
Existing position sensor unworthiness:
When the main stroke lever axis of mounting and adjusting position sensor and finish rolling depress leading screw axis axiality, due to 1700 finishing mill pressure leading screw excesssive gaps, there is too great deviations in position sensor axis and screw mandrel axis, when causing working sensor and lead screw shaft decentraction cause connecting clamp to throw off, break the faults such as disconnected.Reason does not consider that when design attitude sensor finish rolling pressure leading screw and nut thereof are at long term wear excesssive gap, when causing its axis oscillating and rear transformation position sensor to install, axis deviant is large, and position sensor main carriage release lever location sealing gap cross design too small, when sensor moves up and down work along with pressure leading screw, do not have enough gaps inclined to compensate leading screw and the main carriage release lever axis of position sensor when there is diaxon misalignment of axe, because two work package disalignments make and position sensor swings greatly when its work.Often occur that the upper and lower connecting clamp of sensor main carriage release lever loosens, lower connecting clamp breaks the faults that take place frequently such as disconnected, cause product quality accident.
The trouble point existed comprises:
That light face contacts and designs between the main stroke lever of position sensor with connecting clamp between leading screw stirrup, between two connectors, stiction is too small, in addition sensor main stroke lever and leading screw journal offset larger, entrance location sensor connecting clamp design strength is inadequate, and because two cover location sealing cushion rubbers of sensor main stroke lever are by reasons such as the aging serious gap of impact of pressure environment temperature are too small, often cause the locking of sensor main stroke lever, lower connecting clamp loosens or fracture, thus sensor main stroke lever and leading screw are thrown off, the ineffective computer of sensor cannot testing roller physical location size.When steel rolling often there is misalignment of axe in sensor main stroke lever and leading screw, and the little bar of sensor (limiting rod) takes turns that intended diameter is little, and steamboat and its terminal pad often come off, and cause limit inferior fault alarm fault.Change sealing ring and bonding magnet ring etc. to check owing to taking place frequently, overhaul sensor, make frequent removal sensor core, sensor terminals subboard is is frequently plugged and unplugged, Pin contact loose contact, position sensor occurs and often carrys out position zero-bit dropout fault.
Utility model content
Loosen or the problem such as fracture, skew for the upper and lower connecting clamp existed in prior art, solve because problems such as the aging main stroke lockings brought of seal, technical problem to be solved in the utility model is to provide a kind of rolling mill screwdown position sensor.
The utility model realizes like this, a kind of rolling mill screwdown position sensor, comprise the sensor outer housing of one end open, connecting plate is installed, connecting plate is installed be connected with the openend of sensor outer housing, installation connecting plate arranges portal frame device, sensor core is arranged on its top, install in the middle of connecting plate and offer bolt hole for passing main stroke lever, one end of main stroke lever arranges magnet ring, the other end of main stroke lever is coaxially connected with leading screw by connecting stirrup through installing connecting plate, and sensor test rod is fixed on cover on portal frame and becomes owner of in stroke lever.
Sensor core further, is arranged on the top of portal frame device, is joined with bolts by the utility model scheme, and the bolt hole of fixation of sensor core is arranged to adjustable sensor mandrel string holes.
The utility model scheme further, larger than rodmeter diameter 2 ~ 4 millimeters of the bore dia of magnet ring.
The utility model scheme further, portal frame lateral column body is installed limit proximity switch and limit inferior proximity switch, and is arranged limit switch baffle plate on the top of main stroke lever.
Connecting plate bolt hole is installed and amplifies 1.5 millimeters than the diameter of main stroke lever.
Compared with prior art, beneficial effect is the utility model: eliminate existing sensor upper and lower connection rigidity clamp, eliminates because it produces fault.Sensor after the utility model improves can free adjustment magnet ring axially bored line and sensor measurement rod axis.Magnet ring bore dia and the sensor test rod diameter difference of sensor are 2 ~ 4 millimeters, and sensor is installed connecting plate bolt hole amplify 1.5 millimeters when designing than the diameter of main stroke lever, thus make leading screw axis and sensor axis have the adjustment of enough side-play amounts.Solve and axis offset problem is installed.The utility model portable construction is simple, be convenient to install, and broken away from the restriction that crane is installed.Inner detecting sensor core install simple and direct, check, change convenient and time-saving.Used by the tests of 9 months, primary fault does not appear in operational excellence, impact is normal produces little stopping and product quality accident.
