The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:

See Fig. 1, Fig. 2, Fig. 3, the novel rolling mill manipulator, comprise motor 13, sychronisation 12, reductor 1, push pedal 7, enclosed framework 8, guider 9, support roller device 10, be provided with pair of push plates 7 in the enclosed framework 8,7 with enclosed framework 8 tops be provided with guider 9, the bottom is provided with support roller device 10, one thruster plates 7 and is provided with two groups of transmission mechanisms 3, two groups of transmission mechanisms 3 are connected with reductor 1, sychronisation 12, motor 13 respectively successively, and push pedal 7 homonymy sychronisations 12 are connected.

Transmission mechanism 3 comprises splined shaft 4, spline housing 2, hollow leading screw 5, screw 6 compositions, reductor 1 is connected with splined shaft 4, splined shaft 4 is meshed with spline housing 2 in being embedded in hollow leading screw 5, hollow leading screw 5 one ends are provided with screw 6, screw 6 is arranged on the enclosed framework 8, and hollow leading screw 5 tops are connected with push pedal 7.

See Fig. 4, enclosed framework 8 is provided with 4 axle sleeves 19 for the quadra 18 of band lower margin 20 in same horizontal plane, and this axle sleeve 19 minutes two rows be provided with, and two axle sleeves 19 of every row are coaxial.

Among the embodiment, realize that the utility model mainly is made of 7,1 enclosed framework 8 of 3,2 push pedals of 12,4 groups of drive mechanisms of 13,2 groups of sychronisations of 4 motors, wherein the specification of enclosed framework 8, splined shaft 4, leading screw 5 and motor 13 is to determine according to the stroke and the straightening force of manipulator.Push pedal 7 motions are in closed framework 8, and motor 13 finally passes to the push pedal 7 that is positioned at enclosed framework 8 to moment by sychronisation 12, reductor 1, splined shaft 4 transmissions, hollow leading screw 5, screw 6 transmissions, thereby realize the motion and the straightening function of manipulator.

The both sides of manipulator 7 have two motors 13 to link to each other with reductor 1 by sychronisation 12 respectively, wherein sychronisation 12 is made up of two bevel gear reducers and shaft coupling, be provided with clutch apparatus simultaneously, can control motor according to different operating modes by the closure of solenoidoperated cluthes and whether export torque synchronously.

The output shaft of reductor 1 is a female splined shaft, and it and splined shaft 4 are by the splined driving torque.The spline housing 2 in addition that is connected with splined shaft 4, torque just is delivered on the spline housing 2 by two splined on the same splined shaft 4 like this.Since spline housing 2 be by bolted on hollow leading screw 5, rotate when motion when splined shaft 4 is subjected to torque like this, hollow leading screw 5 also can rotate and biography be decided torque with spline housing 2.Owing in common spline transmission, have certain clearance, the situation of not feeling relieved can appear swinging up and down in splined shaft, be unfavorable for the steady of transmission like this, therefore the spline transmission of the utility model milling train manipulator has adopted spline self-centering structure to handle, splined shaft 4 utilizes self-centering characteristic to regulate automatically in transmission process like this, all the time keep concentric with hollow leading screw 5, guarantee stable drive, efficient.

The screw 6 that is connected with hollow leading screw 5 is fixed on the enclosed framework 8, because enclosed framework 8 lower margins 20 are to be fixed on the basis, when leading screw 5 rotations, screw 6 is fixed in the axle sleeve 19 motionless, thereby leading screw 5 will move forward and produce thrust, travel forward thereby promote to be installed on the leading screw 5 push pedal 7, thereby produce thrust.

Between framework 8 and the push pedal 7 dust cover 11 is installed, this dust cover can stretch along with the reciprocating motion of push pedal 7, this dust cover also has the oil resistant corrosion resistance simultaneously, lubricating oil on the leading screw 5 can also reclaim by return line after dropping on dust cover 11 in motion process like this, has guaranteed the integrality and the recyclability of lubricating system.

Steady, smooth and easy in order to ensure that push pedal 7 is moved in enclosed framework 8, push pedal 7 tops are equipped with guider 9, and the bottom is equipped with support roller device 10.Guider 9 is made up of two directive wheels, it can prevent thrust plate 7 in motion process, occur about the skew situation.Support roller device 10 is made up of rolling pulley, on the enclosed framework 8 tracks is arranged, push pedal 7 is carried out rolling movement by support roller device 10 on enclosed framework 8, has significantly reduced resistance suffered in the motion process.Push pedal 7 just can not depart from the definitive orbit on the enclosed framework 8 in traveling process down guider 9 and support roller device 10 common auxiliary, has also reduced push pedal 7 suffered resistance in advancing simultaneously, has improved utilization efficiency of energy.

Adopt motor 13 as power source, utilize spline, lead screw transmission that turning moment is converted to linear thrust and realize that manipulator can provide the function of big straightening force.
