Abstract
The utility model relates to a self-centering chuck for face-lifting of a tire, which comprises a chuck, movable claws and a conical head, wherein the conical head is installed inside an inner hole of the chuck, a plurality of movable claws are uniformly distributed on the chuck, the movable claws are installed on the chuck through a connection rod, the lower end of the connection rod is contacted with the conical head, and the conical head is connected with a movable mechanism. The lower end of the connection rod is provided with an idler wheel. The movable mechanism can adopt an air cylinder, an oil cylinder or a helical movable mechanism. The conical head with taper drives the movable claws of the chuck to simultaneously extends out so as to realize the automatic centering of the tire, so that the self-centering chuck is safe and reliable and is convenient to use.
Description
Technical field
The utility model relates to the chuck that is used for the clamping tire in a kind of rubber tyre renovation on the detreader, belongs to tyre rebuilding mill tire equipment technical field.
Background technology
Junked tire is overhauled and utilized is the main path of tire resource circulation utilization, also is the major measure of junked tire decrement.Tire cost 70% on carcass, the just crown of wearing and tearing.Tyre rebuilding is exactly that the part that is ground off with damaged is handled through special process, change new rubber combination, make worn tire become a complete tire, its technical process generally is earlier with the size of old tire crown polishing to the best, to be coated on the carcass surface of the old tire of handling through polishing again through the tread rubber of high-pressure molding, become one through sulfuration adhesion.
Detreader is to be used to polish the equipment on old tire surface, mainly comprises frame, cutter head, cutter head tumbler, cutter head mobile device, cutter head frame, tire chuck for installing, tyre rotation device and electric apparatus control apparatus.On the at first rack-mounted tire chuck for installing of old tire, rotate under the drive of tyre rotation device, cutter head rotates under the drive of cutter head tumbler again, and the cutter head frame moves simultaneously, drives cutter head and polish satisfactory tire section exterior contour.The tire chuck for installing generally comprises a fixed-site chuck and a mobile chuck, be installed in the both sides of frame relatively, mobile chuck drives by rack-mounted cylinder or oil cylinder and moves, and by moving of mobile chuck rim clamp is held in fixedly between the chuck and mobile chuck.
At present, the tire bead diameter that contacts with chuck and the diameter of outer chuck are also unequal, and tire mouth and chuck are gapped when causing installation, make the center of circle of tire and the center of circle off-centre of chuck.Tire after the polishing is not circular, but oval, can make the quick heel and toe wear of tire, and damaging axle bearing even causing to blow out influences safety.This gap is because the difference of tire brand causes.
Summary of the invention
The utility model is at the problem that existing detreader chuck centering technology exists, and provides a kind of and can realize self-centering, safe and reliable tyre rebuilding self-centering chuck.
Tyre rebuilding self-centering chuck of the present utility model adopts following technical solution:
This tyre rebuilding self-centering chuck comprises chuck, moving jaws, conehead, connecting rod and travel mechanism, conehead is installed in the endoporus of chuck, is evenly distributed with moving jaws on the chuck, and moving jaws is installed on the chuck by connecting rod, the lower end of connecting rod contacts with conehead, and conehead is connected with travel mechanism.
The lower end of connecting rod is equipped with roller.
Travel mechanism can adopt cylinder, hydraulic cylinder or spiral travel mechanism.
The utility model drives the self-centering that the movable claw on the chuck stretches out the realization tire simultaneously by the conehead of band tapering, and is safe and reliable, easy to use.

The specific embodiment
As depicted in figs. 1 and 2, tyre rebuilding self-centering chuck of the present utility model comprises chuck 4, moving jaws 5, cylinder 1 and conehead 7.Conehead 7 is installed in the endoporus of chuck 4.Moving jaws 5 has six (quantity also can be determined according to the size of chuck 4), is evenly distributed on the chuck 4, and moving jaws 5 is provided with connecting rod 6, is installed on the chuck 4 by connecting rod 6, and the lower end of connecting rod 6 is equipped with roller, and roller contacts with conehead 7.The cylinder body of cylinder 1 is installed on the frame 2 of detreader, and the piston rod of cylinder 1 is connected with conehead 7 with a thrust bearing by a ball bearing.Chuck 4 is installed on the installing rack 3 by a ball bearing and a thrust bearing, and installing rack 3 is fixed on the frame 2 of detreader.In order to make moving jaws 5 self-returns, between chuck 4 and moving jaws 5, can be provided with spring (not drawing among the figure).
Drive conehead 7 by cylinder 1 and move, each moving jaws 5 that conehead 7 drives on the chuck 4 again moves simultaneously, plays the self centering purpose of tire.Cylinder 1 also can use other travel mechanisms such as hydraulic cylinder, spiral travel mechanism to replace, and these replacements all are protection domains of the present utility model.
Claims (2)
1. tyre rebuilding self-centering chuck, comprise chuck, moving jaws, conehead, connecting rod and travel mechanism, it is characterized in that: conehead is installed in the endoporus of chuck, be evenly distributed with moving jaws on the chuck, moving jaws is installed on the chuck by connecting rod, the lower end of connecting rod contacts with conehead, and conehead is connected with travel mechanism.
