Technical Field

The invention relates to the technical field of adjusting devices, in particular to a ratchet adjusting device for position change of a backing bearing roller.

Background

The invention relates to the spatial positioning and adjustment of multi-roll (8-roll and over 8-roll) rolling mill backing bearing rolls in a frame. The positioning of the "backing bearing roll" consisting of several backing bearings in a cluster mill is the basis for the stability of the cluster mill roll train. The roll diameters of the individual layers of the roll system vary continuously due to variations in the thickness of the rolled workpiece, and due to wear of the roll system during operation and the grinding of the rolls from time to eliminate cracks in the roll surfaces. The spatial position of the backing bearing roll, which is the basis for the position of the roll system, in the rolling mill needs to be constantly adjusted.

The existing design is adjusted by the mandrel eccentricity of the backing bearing roll, see pennsheng '20-roll mill and high-precision cold-rolled strip production' 2007 edition of the publication of metallurgy industry.

During rolling, the back lining bearing roller is stressed greatly, and a large torsional moment can be generated by a small eccentric amount. Because the outer diameter of the backing bearing is far larger than the shaft diameter of the mandrel, namely the balancing moment arm is far smaller than the torsion moment arm, the clamping force of the eccentric mandrel needs to be quite large to balance the torsion moment. And the torsional stress borne by the mandrel is also large.

The invention utilizes the eccentricity of the outer circle and the inner hole of the saddle to balance the torsional force, thereby not only increasing the adjustment range of the backing bearing roller, but also thoroughly eliminating the torsional stress born by the core shaft and improving the space positioning and the adjustment working condition of the backing bearing roller.

Disclosure of Invention

In view of the shortcomings of the prior art, it is an object of the present invention to provide a ratchet adjusting device for changing the position of a backing bearing roller, which has the advantage of adjusting the position of the backing bearing roller.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a back lining bearing roller position variation's ratchet adjusting device, includes the frame, install the tooth lock in the frame, one side of tooth lock is provided with eccentric saddle, the inside of eccentric saddle is provided with back lining bearing roller, the axial lead of back lining bearing roller and the axial lead dislocation of the dabber of wearing to establish in back lining bearing roller, eccentric saddle is provided with the stabilizing gear who meshes with the tooth lock towards one side of tooth lock.

Through adopting above-mentioned technical scheme, when the adjustment, let eccentric saddle rotate, after eccentric saddle no longer rotates, drive tooth lock removes until both meshings towards stabilizing gear's direction, and tooth lock can restrict stabilizing gear's rotation. The core shaft of the backing bearing roller eccentrically moves around the circle center of the sector of the saddle to drive the backing bearing roller to move or position in the inner cavity of the frame.

The invention is further configured to: one side of eccentric saddle is provided with the slider of being connected with eccentric saddle rotation, the middle part of slider articulates there is the dwang, the one end that the slider was kept away from to the dwang is provided with the rotation motor.

Through adopting above-mentioned technical scheme, the setting of slider can make things convenient for the rotation of eccentric saddle, reduces the friction between eccentric saddle and the frame. In addition, when the eccentric saddle does not need to move, the rotating motor is started to drive the rotating rod to rotate so as to drive the sliding piece to rotate to the inside of the eccentric saddle, and the spontaneous movement of the eccentric saddle is avoided.

The invention is further configured to: the slider includes the dead lever of being connected with the dwang rotation, the both ends of dead lever are provided with the gyro wheel.

Through adopting above-mentioned technical scheme, the dead lever rotates under the effect of dwang to with the surface contact of frame, eccentric saddle can conveniently rotate under the effect of gyro wheel afterwards.

The invention is further configured to: the frame is provided with support piece that is in eccentric saddle both sides, support piece includes the support cylinder with frame fixed connection, support cylinder is connected with the backup pad.

Through adopting above-mentioned technical scheme, when eccentric saddle need not rotate, can start the support cylinder and drive the backup pad and remove, remove when the backup pad and produce the extrusion back as for eccentric saddle, the backup pad that is in eccentric saddle both sides will restrict the rotation of eccentric saddle.

The invention is further configured to: the utility model discloses a safety gear lock, including the tooth lock, the tooth lock is provided with the first gag lever post of one side fixedly connected with of saddle, be provided with the second gag lever post parallel with first gag lever post on the tooth lock, the top of first gag lever post is provided with connects the rope, the upper end of second gag lever post is provided with the solid fixed ring that is used for connecting the rope and passes, the middle part of second gag lever post is provided with the live-rollers, the middle part of live-rollers is provided with the depressed groove that holds the connection rope, the middle part fixed connection of the one end of keeping away from first gag lever post and live-rollers of connection rope, be provided with the locating part that.

Through adopting above-mentioned technical scheme, after eccentric saddle no longer rotates, let the live-rollers rotate around the axial lead of self, the live-rollers can drive and connect the rope and rotate to the side of live-rollers, play the effect of drawing in and connecting the rope, after connecting the rope and being in the state of tensioning, utilize the removal of locating part restriction tooth lock, first gag lever post and second gag lever post will be in the state of mutual restriction this moment, thereby avoid first gag lever post and second gag lever post to produce relative movement's action, consequently tooth lock and stabilizing gear can not produce relative removal.

The invention is further configured to: the gear lock is characterized in that a fixed block matched with the clamping groove is arranged above the gear lock, a rotating gear is sleeved on the outer ring of the rotating roller and meshed with a gear strip, the clamping groove is formed in the middle of the gear strip, and a fastening bolt at one end of the clamping groove penetrates through the gear strip.

Through adopting above-mentioned technical scheme, live-rollers pivoted in-process live-rollers will drive the running gear and rotate, and the rotation of running gear will drive the gear rack and remove along the length direction of self, and the gear rack will move towards the direction of tooth lock, and the fixed block on the tooth lock will block into the centre gripping inslot, and along with the removal of gear rack, the fixed block will be stronger and stronger with the extrusion of the cell wall in centre gripping groove.

The invention is further configured to: and rubber is arranged on the groove wall of the clamping groove.

Through adopting above-mentioned technical scheme, the setting of rubber can strengthen the frictional strength between the cell wall of fixed block and centre gripping groove.

In conclusion, the invention has the following beneficial effects:

when the gear lock is adjusted, the eccentric saddle is rotated, and after the eccentric saddle does not rotate any more, the gear lock is driven to move towards the direction of the stabilizing gear until the eccentric saddle and the stabilizing gear are meshed, and the gear lock can limit the rotation of the stabilizing gear. The core shaft of the backing bearing roller eccentrically moves around the circle center of the sector of the saddle to drive the backing bearing roller to move or position in the inner cavity of the frame.
