Detailed description of the invention
Below in conjunction with accompanying drawing and concrete better embodiment, the application is described in further detail.
As shown in Figure 1, a kind of energy-saving environment-friendly rolling mill guiding device with zero offset capability, comprises inlet guide, outlet guide and can regulate the left side wall of inlet guide and the control system of right side wall spacing.
Above-mentioned control system comprises servomotor 10 and leading screw; Can also comprise computer, interface card, driver, code-disc, interface card etc., concrete setting and enforcement principle can be the patent application of 200910012061.9 with reference to application number in background technology.The bearing matched with leading screw all adopts self-lubricating mode, thus more energy-conserving and environment-protective.
Leading screw comprises the synchronous regulation mechanism of front initiatively leading screw 60, front passive leading screw, rear active leading screw, rear passive leading screw formation.The concrete setting of synchronous regulation mechanism and and implement principle, can be also the patent application of 200910012061.9 with reference to application number in background technology.
Servomotor 10 connects output shaft 20 by the first shaft coupling 30, and the other end of output shaft 20 connects front initiatively leading screw 60 by the second shaft coupling 50.Second shaft coupling 50 and be interference fit between output shaft 20 and front active leading screw 60.
Servomotor 10 is fixed in motor fixing seat 12, and the first shaft coupling 30 is fixed in positioning seat 40.Between positioning seat 40 and motor fixing seat 12, be connected by several crossed countersunk head screws 41.
Motor shaft 11 interference fit of the first shaft coupling 30 and servomotor 10,
One end that output shaft 20 is connected with servomotor 10 is disposed with ring-type positioning convex portion 21 from left to right and ring-type stops protuberance 22.
Spring 31 is provided with in the first shaft coupling 30 cavity between motor shaft 11 and output shaft 20; Be positioned on the first shaft coupling 30 inner surface above ring-type positioning convex portion 21 and be provided with the centring ring 22 that can match with ring-type positioning convex portion 21; Be positioned on the first shaft coupling 30 inner surface that ring-type stops on the left of protuberance 22 and be at least evenly provided with two elastic cylindrical pins 33, be preferably four, but also can be two, three or more.
Front active leading screw 60 arranged outside has the striking gear 70 that front initiatively leading screw 60 can be driven to move axially to the right.Striking gear 70 has the following two kinds preferred embodiment:
Embodiment 1
Striking gear 70 is match with the screw thread of front active leading screw 60 and the transmitting gear of slippage before and after energy.
Embodiment 2
Striking gear 70 is the expansion link that height can be elevated, and the inner side of expansion link has the groove matched with the screw thread of front active leading screw 60.
Inlet guide is also connected with overall moving-out device; Overall moving-out device comprises hydraulic cylinder and travelling carriage, and hydraulic cylinder and travelling carriage are arranged on the bottom of guiding protector for entry.The setting of overall moving-out device, when can make on-bne repair and change consumable accessory, efficiency is high, labour intensity is little, and operating rate of rolling mill is high.
Above-mentioned energy-saving environment-friendly rolling mill guiding device, when normally using, all elastic cylindrical pins 33, are all in elongation locking state, and elastic cylindrical pin 33 can form tight fit with output shaft 20 after extending, thus make motor shaft 11 and output shaft 20 form integrative-structure.After servomotor 10 runs a period of time, carry out calibrating and revise according to setting-up time to output shaft 20, can avoid output shaft 20 that the faults such as stuck or idle running occur.In addition, when an error occurs, do not need installing/dismounting servomotor 10, can automatically revise fast, thus operating efficiency is high, long service life, simple to operate.
When reaching above-mentioned setting-up time or output shaft 20 breaks down, the automatic correcting method of above-mentioned energy-saving environment-friendly rolling mill guiding device, comprises the steps:
The first step, makes all elastic cylindrical pins 33 automatically shrink, and removes the first shaft coupling 30 and being fixedly connected with between output shaft 20.
Second step, striking gear 70 works: striking gear 70 and front active leading screw 60 near and with the threaded engagement of front active leading screw 60, under the drive of striking gear 70, front active leading screw 60 is pressed shown in Fig. 1, move axially to the right, thus drive output shaft 20 to move axially to the right; In the process that output shaft 20 moves axially to the right, namely complete an auto modification; Now, striking gear 70 stops stirring, and returns to original position.
3rd step, output shaft 20 resets: in the process that output shaft 20 moves axially to the right, meeting Compress Spring 31, after striking gear 70 stopping is stirred, spring 31 resets, output shaft 20, under the effect of spring 31, moves axially left, and ring-type stops that protuberance 22 can carry out stopping to the displacement of spring 31 and limit; Ring-type positioning convex portion 21 pairs of output shafts 20 position, and prevent output shaft 20 from shaking.
4th step, repeat the above-mentioned first step to the 3rd step, number of repetition, can determine according to actual needs, all elastic cylindrical pins 33 of rear locking, makes motor shaft 11 and output shaft 20 again form integrative-structure, completes auto modification.
