Description
Technical field
The utility model relates to a kind of heavy-duty mill roll weldering bed hydraulic tailstock.
Background technology
Large-scale roller, in welding process, owing to heat-treating, along with the rising of temperature, can make the axial dimension of workpiece change.And traditional tailstock is leading screw, screw structure, there is auto-lock function, so easily cause roll axial bending.Originally manually can only adjust tailstock, along with the change of temperature, stroke also can be different, if adjustment not in time, roll mandrel is comparatively large to change in size, the bending or roll of roll shaft can occur and come off.
Summary of the invention
The purpose of this utility model is to provide a kind of heavy-duty mill roll weldering bed hydraulic tailstock, at weldering tailstock seat, hydraulic cylinder is installed, advanced top to welding workpiece pre-tightening by PLC hydraulic control cylinder, moving forward and backward of the automatic regulator solution cylinder pressure of stroke that can produce because of variations in temperature according to workpiece, make top can to workpiece auto lock, effectively prevent roll bending or come off in welding process., toply freely can to rotate along with workpiece meanwhile, the mutual wearing and tearing between top and workpiece can be prevented.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of heavy-duty mill roll weldering bed hydraulic tailstock, comprise hydraulic cylinder, adpting flange, end cap A, end cap B, tailstock mandrel, single direction thrust ball bearing, taper roll bearing, top, dust cap, dead head, needle bearing, described hydraulic cylinder body is connected with the end of tailstock by bolt, hydraulic cylinder piston rod stretches in tailstock, end winding support adpting flange, adpting flange is connected with tailstock mandrel by bolt, the other end of tailstock mandrel is bolted dead head, the top axle center being arranged on dead head, dead head and top between successively needle bearing is installed, single direction thrust ball bearing, taper roll bearing, needle bearing is arranged on one end that is top and dead head, end cap A is by the outer ring of needle bearing and dead head axial restraint, end cap B is by the inner ring of needle bearing and top axial restraint, taper roll bearing and single direction thrust ball bearing are axially fixed in the other end of dead head by dust cap.
Compared with prior art, the beneficial effects of the utility model are:
A kind of heavy-duty mill roll weldering bed hydraulic tailstock, at weldering tailstock seat, hydraulic cylinder is installed, advanced top to welding workpiece pre-tightening by PLC hydraulic control cylinder, moving forward and backward of the automatic regulator solution cylinder pressure of stroke that can produce because of variations in temperature according to workpiece, make top can to workpiece auto lock, effectively prevent roll bending or come off in welding process., toply freely can to rotate along with workpiece meanwhile, the mutual wearing and tearing between top and workpiece can be prevented.

Detailed description of the invention
Below in conjunction with Figure of description, utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following embodiment.
As Figure 1-Figure 2, a kind of heavy-duty mill roll weldering bed hydraulic tailstock, comprises hydraulic cylinder 1, adpting flange 4, end cap A6, end cap B5, tailstock mandrel 7, single direction thrust ball bearing 8, taper roll bearing 9, top 10, dust cap 11, dead head 12, needle bearing 13, described hydraulic cylinder 1 cylinder body is connected by the end of bolt with tailstock 3, hydraulic cylinder piston rod 2 stretches in tailstock 3, end winding support adpting flange 4, adpting flange 4 is connected with tailstock mandrel 7 by bolt, the other end of tailstock mandrel 7 is bolted dead head 12, and the top 10 axle centers being arranged on dead head 12, are provided with needle bearing 13 successively between dead head 12 and top 10, single direction thrust ball bearing 8, taper roll bearing 9, needle bearing 13 is arranged on one end of top 10 and dead head 12, end cap A6 is by the outer ring of needle bearing 13 and dead head 12 axial restraint, end cap B5 is by the inner ring of needle bearing 13 and top 10 axial restraints, and single direction thrust ball bearing 8 and taper roll bearing 9 are axially fixed in the other end of dead head 12 by dust cap 11.
Positioning key 14 is installed between tailstock mandrel 7 and tailstock 3, tailstock mandrel 7 radial rotating can be prevented.
Tail end top 10 is installed needle bearing 13 and is played the effect of counterweight, prevents top 10 heads from sinking because of deadweight, make top 10 remain with tailstock mandrel 7 on the same axis.
Single direction thrust ball bearing 8 and taper roll bearing 9 are also play the effect into top 10 location, make top 10 axis and radial displacement can not occur.
The inner ring of three bearings all with top 10 interference fit, outer ring all with dead head 12 interference fit, make top 10 in the course of work of top tight workpiece, can rotate along with workpiece, thus prevent from producing wearing and tearing because of friction between top 10 and workpiece.
The utility model adopts hydraulic cylinder 1 to realize welding holding out against of bed tailstock centre 10 pairs of large-scale roller welding work pieces, what can produce because of variations in temperature according to welding work pieces under the control of PLC stretches, the pressure of regulator solution cylinder pressure 1, roll extends tailstock centre 10 and bounces back, roll shortens tailstock centre 10 and stretches out, tailstock locked hydraulic cylinder 1 ensures all the time in the range of pressure values of a setting, to guarantee to be consistent to the pretightning force of welding work pieces, thus effectively prevent roll from bending in welding process or coming off.
Be only the general principle of the utility model patent above, not impose any restrictions the utility model patent, every foundation the utility model carries out equivalent variations and modification to it, all within the category of the art of this patent protection scheme.
