The utility model discloses a regulation pad of different specifications can compensate the wearing and tearing volume of convex surface pad to keeping the work elevation of lead screw concave surface pad and convex spherical pad, avoiding the elevation low excessively, concave surface pad outer fringe interferes the contact to form the phenomenon of spinning with the thrust block pedestal, simultaneously, also can make convex spherical pad used repeatedly, reduction use cost.
Description
Technical field
The utility model belongs to metal shaping equipment technical field, is specifically related to a kind of connection joint of rolling mill screwdown device.
Background technology
The connection joint of rolling mill screwdown device is the flexible vitals transmitting power, and its quality overall performance to screwdown gear transmitting roll-force plays vital effect.But the convex spherical pad in existing connection joint adopts copper product to make, its material is softer, easy wearing and tearing, the work absolute altitude of screw mandrel concave surface pad and convex spherical pad is caused to reduce, concave surface pad outer rim is interfered with thrust block seat pedestal and is contacted, and formation is spinned, time serious, concave surface pad outer rim also can embed in thrust block seat pedestal, and convex spherical pad cannot successfully be departed from screw mandrel concave surface pad.Meanwhile, the convex spherical pad changed can not reuse due to wearing and tearing, can only work as copper scrap and reclaim, and cause spare part expense to remain high, use cost is high.
For the problems referred to above, be necessary to improve the structure in existing connection joint, pressure head convex spherical pad is recycled, and screw mandrel concave surface pad and thrust block seat pedestal are not interfered, thus effectively reduce cost of equipment, stop pressure head and to spin accident, guarantee production direct motion.
Utility model content
In view of this, the purpose of this utility model is the connection joint providing a kind of rolling mill screwdown device, causes so that the convex spherical pad solving prior art existence is easy to wear the problem that absolute altitude change causes pressure head to spin and use cost is high.
The purpose of this utility model is achieved through the following technical solutions:
The connection joint of rolling mill screwdown device, comprise thrust block seat, be fixed on convex spherical pad in thrust block seat bore and concave spherical surface pad intermeshing with convex spherical pad, equal pressure pad, bearing structure and supporting construction is disposed with below described convex spherical pad, be connected and fixed with screw mandrel above described concave spherical surface pad, be provided with the spacer that high-abrasive material is made between described convex spherical pad and equal pressure pad, described spacer arranges multiple specification by thickness difference.
Further, between described concave spherical surface pad and the bore of thrust block seat for gap is arranged.
Further, described gap is one side gap 0.5-3mm.
Further, the convex surface of described convex spherical pad is provided with multiple annular oil groove for storing lubricating oil, described annular oil groove is uniform toward extension along the convex surface center of convex spherical pad.
Further, the cross section of described annular oil groove is crescent.
The beneficial effects of the utility model are:
The utility model can be compensated the wear extent of convex surface pad by the spacer of different size, thus keep the work absolute altitude of screw mandrel concave surface pad and convex spherical pad, avoid absolute altitude too low, concave surface pad outer rim interferes with thrust block seat pedestal the phenomenon contacting and formed and spin, simultaneously, also convex spherical pad can be made to reuse, reduce use cost.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be realized by description below and obtain.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of the utility model convex spherical pad.
Detailed description of the invention
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only in order to the utility model is described, instead of in order to limit protection domain of the present utility model.
As shown in the figure, the connection joint of the rolling mill screwdown device of the present embodiment, comprise thrust block seat 1, be fixed on the convex spherical pad 2 in thrust block seat 1 bore and concave spherical surface pad 3 intermeshing with convex spherical pad 2, equal pressure pad 4 is disposed with below described convex spherical pad 2, bearing structure and supporting construction, be connected and fixed with screw mandrel 4 above described concave spherical surface pad 3, the spacer 5 that high-abrasive material is made is provided with between described convex spherical pad 2 and equal pressure pad 6, described spacer 5 arranges multiple specification by thickness difference, concrete, can arrange by concave spherical surface pad 3 and the acceptable maximal work absolute altitude of convex spherical pad 2 and the difference of nominal operation absolute altitude, when convex spherical pad 2 wearing and tearing reach this difference, the spacer of a replaceable thick specification, the compensation of identical difference can be obtained, this makes to change conveniently, simply, efficiently, can monitor in real time this work absolute altitude as more excellent selection, such as camera, scanner or position sensor etc., the present embodiment adopts the axial location of position sensor 7 pairs of concave spherical surface pads 3 to monitor, when reaching certain value, send replacing signal.
The present embodiment can be compensated the wear extent of convex surface pad by the spacer of different size, thus keep the work absolute altitude of screw mandrel concave surface pad and convex spherical pad, avoid absolute altitude too low, concave surface pad outer rim interferes with thrust block seat pedestal the phenomenon contacting and formed and spin, simultaneously, also convex spherical pad can be made to reuse, reduce use cost, in addition, also monitored by the axial location of position sensor to concave spherical surface pad, obtain real-time work absolute altitude, send signal, make operation accurate, timely, be beneficial to the connectivity of rolling work, increase work efficiency.
In the present embodiment, for gap is arranged between described concave spherical surface pad 3 and the bore of thrust block seat 1, after convex spherical pad 2 weares and teares, even if concave spherical surface pad 3 declines enter the bore of thrust block seat 1, both also can not produce interference, further increase the security of operation, preferred gap is one side gap 0.5-3mm or double-faced clearance 1-6mm, and this interference occurs hardly.
In the present embodiment, the convex surface of described convex spherical pad 2 is provided with multiple annular oil groove 8 for storing lubricating oil, described annular oil groove 8 is uniform toward extension along the convex surface center of convex spherical pad, make lubricant housings even, lubricant effect is better, the cross section of described annular oil groove 6 is crescent, avoids oil groove to cross the dark intensity reducing convex spherical pad 2.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of the technical program, it all should be encompassed in the middle of right of the present utility model.
