Description
Technical field
The utility model relates to tooth positioning devices outside a kind of plate-straightening machine working roll spline, belong to metallurgy rolling equipment skill
Art field.
Background technique
Plate-straightening machine is the important equipment on hot rolled steel plate production line, and main function is the straight of guarantee steel plate
Degree, service performance directly decides the quality of plate finished product, particularly important to plate surface quality.
Working roller of straightening machine quantity is more, when failure, needs to replace simultaneously.In new working roll push-on process, by
It is in not can guarantee that all working roller spline external tooth and corresponding universal shaft spline housing internal tooth is accurately circumferentially positioned, cause often
Individual work roller spline external tooth and universal shaft spline housing internal tooth dieback occurs, the problems such as docking, entire roller system be can not be successfully
Push-in is in place；Simultaneously because limitations, it is difficult directly to observe working roll spline external tooth and is docked with universal shaft spline housing internal tooth
Situation.When production scene encounters such problem, it can only take and remove universal shaft and universal shaft spline housing one by one, be pushed into new roller system
Afterwards, then one by one universal shaft and universal shaft spline housing are connected, influences the roll change efficiency of working roller of straightening machine, when some straightener roll-changings
Between even will be up to 26 hours as long as, seriously affect normal rhythm of production.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of positioning of plate-straightening machine working roll spline external tooth to fill
It sets, rapidly and accurately straightener new roller system working roll spline external tooth can be positioned, to promote the roll change effect of working roller of straightening machine
Rate guarantees normal production.
The technical solution for solving above-mentioned technical problem is:
The outer tooth positioning device of plate-straightening machine working roll spline, including upper mounted plate, multiple external tooth positioning plates and lower fixation
Plate；External tooth positioning plate includes shank and curved portion, and one end of shank and the midpoint of curved portion are fixed, the other end and upper mounted plate or
Bottom plate is fixed；Multiple internal tooths, the spline external tooth phase of multiple internal tooths and working roller of straightening machine are distributed on the inner arc of curved portion
Matching.
The outer tooth positioning device of above-mentioned plate-straightening machine working roll spline, the multiple external tooth positioning plate are divided into two groups, the
One group of shank upper end is connected and fixed with upper mounted plate underrun bolt, nut, second group of shank lower end and bottom plate
Upper surface is connected and fixed by bolt, nut.
The outer tooth positioning device of above-mentioned plate-straightening machine working roll spline, on the curved portion inner arc of the external tooth positioning plate point
3 internal tooths are furnished with, the facewidth, height of teeth top and the modulus of 3 internal tooths match with the spline external tooth of working roller of straightening machine respectively.
The application method of the utility model are as follows:
When needing replacing straightener top working roll roller system, loose bolts and nut first, enable external tooth positioning plate with
Bolt is axis rotation；The upper mounted plate for being equipped with multiple external tooth positioning plates is moved to the old working roll roller side of fastening, pushes external tooth
Positioning plate withstands spline housing external tooth end face, so that 3 internal tooths of external tooth positioning plate and spline housing external tooth are intermeshed, guarantees engagement
After in place, external tooth positioning plate is elapsed into about 150mm to the spline external tooth other end along working roll spline external tooth is axial, it is therefore an objective to be
Guarantee external tooth positioning plate can axially be passed through in entire working roll spline external tooth and accurate positioning, then passes through fastening bolt
External tooth positioning plate is completely fixed with nut；The external tooth positioning plate adjusted is put into the roller side of fastening of new working roll, rotation is rectified
Straight roller engages the spline housing external tooth of new working roll roller system accurately with the multiple external tooth positioning plates adjusted, and completes on straightener
Working roll roller system it is circumferentially positioned, to realize the quick-replaceable of top working roll roller system；Using the achievable lower work of identical method
Make the quick-replaceable of roller roller system.
The outer tooth engagement of the spline housing that the utility model first fastens external tooth positioning plate and old working roll roller, realizes that external tooth is fixed
Then the accurate positionin of position plate, and fixing bolt and nut pass through the external tooth positioning plate fixed and new working roll roller system again
The outer tooth engagement of spline housing, so that the external tooth of new roller system spline housing and the spline housing external tooth of old roller system are in identical position, in this way
The spline housing external tooth of new roller system can smoothly be pushed into along the position of original old roller system spline housing external tooth and spend with former roller system
Key covers the intermeshing universal shaft spline housing internal tooth of external tooth, solves the problems, such as that roller system is difficult to be pushed into place, has prevented the replacement of roller system
Recurrent working roll spline external tooth and universal shaft spline housing internal tooth dieback in the process, are asked so as to cause the technology that do not dock
Topic.
The beneficial effects of the utility model are:
The quick circumferentially positioned of upper and lower working roller of straightening machine spline external tooth may be implemented in the utility model, avoids working roll
The generation of universal shaft spline housing internal tooth and straightener spline assembly tooth form misalignment, realizes that disposable push roller arrives in replacement process
Position, greatly improves the replacement efficiency of working roller of straightening machine, ensure that normal production.The utility model has structure simply, again
The advantages that light, easy to operate, at low cost, dismounting is rapid, and positioning accuracy is high is measured, solves current each medium plate mill's roller system of straightening machine more
Change that the time is long, cumbersome technical problem.
