Abstract

The utility model relates to a manipulator centering device for a tyre moulding vulcanizer, which is composed of a support frame 1, a guide sleeve 3, a centering rod 4, a press cover 2 and a compression spring 5. The support frame is fixed on a fixed disk 6 of a manipulator, and the center of the support frame is vertical and coaxial with the center of the fixed disk. The centre of the support frame is provided with the vertically downward guide sleeve, and the centering rod is sheathed in the guide sleeve. The upper end of the centering rod is provided with the press cover, and the centering rod vertically downwards passes through the central hole of the fixed disc to expose a sheathing head at the lower end. The sheathing head is provided with a trepan boring which is sheathed with the head part of a piston rod 9 of a central mechanism, and the centering rod is also sheathed with the compression spring. The utility model has the advantages of high speed and high precision for installing the tyre and centering.

Description

Tire forming vulcanizer manipulator centralising device

The utility model relates to the tire forming vulcanizer manipulator, and tool is stopped relevant with the centralising device of Type B tire forming vulcanizer manipulator.

In the tire shaping vulcanizing process, can the manipulator of tire shaping vulcanizing place the tire base impartially on the central authority of tire forming vulcanizer and make both complete coaxial meetings directly have influence on the Forming Quality of tire.The existing mechanical hand is not owing to there is special centralising device, but centering is located in the flexible and rotation that relies on the pivoted arm of manipulator, so its location is centered in radially and the circumferential deviation that all exists, affect the Forming Quality of tire, therefore, each tire plant in dress tire operation often earlier with manipulator with tire base centering mechanism on, manual according to circumstances by the operative employee again with tire base normotopia, also not only increase operative employee's trouble and danger, also be difficult to the centering requirement that reaches desirable simultaneously.

The purpose of this utility model is the centralising device that will disclose a kind of tire forming vulcanizer manipulator to the public, it can make manipulator with fetus exactly on the centering mechanism, thereby greatly improve the coaxial precision of manipulator calvus and central authority, and finally improve the first cure quality of tire.

The utility model is become by bracing frame, fairlead, centering rod, gland and compression spring set.Umbrella frame frame shape bracing frame is fixedly mounted on the fixed disk of manipulator of tire forming vulcanizer, the bracing frame center is coaxial with the fixed disk central vertical, and connecting vertically downward a fairlead in the bracing frame center fixation, in the fairlead again suit centering rod, the gland that prevents that centering rod from skidding off downwards from fairlead is equipped with in the centering rod upper end, the centering rod lower end is passed manipulator fixed disk centre bore vertically downward and is exposed the pullover of lower end, the pullover center of this lower end has a trepanning that can entangle the central authority piston rod head, simultaneously, in the centering rod outside, be set with a compression spring between the pullover and upper end fairlead in its lower end, if pushing tow centering rod lower end is pullover, then centering rod can move upward in fairlead, if pushing tow not, then centering rod under the effect of compression spring automatically withdrawal reset.

The utlity model has following advantage: 1, because the application of this centralising device on manipulator, make the catching tire base calvus on the manipulator fixed disk realize coaxial by centering rod and central authority piston rod, this just fundamentally eliminated both radially with the deviation of circumferencial direction, improved matched moulds quality and the final first cure quality that improves tire; 2, owing to the realization of mechanical centering, exempted the trouble of artificial centering, this has not only shortened the dress tire time, has improved work efficiency, has also avoided the operative employee by hand with the operational hazards of tire base normotopia simultaneously, has ensured the safety that the workman produces.

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:

Fig. 1, the shape and structure schematic diagram of facing of the present utility model

Fig. 2, plan view shape structural representation of the present utility model

As depicted in figs. 1 and 2, the utility model is made up of bracing frame 1, fairlead 3, centering rod 4, gland 2 and compression spring 5.Bracing frame 1 is a umbrella frame frame shape, and its supporting leg is fixed on by screw on the fixed disk 6 of manipulator of tire forming vulcanizer; The bracing frame center is coaxial with the fixed disk center; Connecting vertically downward a fairlead 3 in the bracing frame center fixation, in the fairlead again suit centering rod 4; A gland 2 that prevents centering rod landing from fairlead downwards is equipped with in the upper end of centering rod, the centering rod lower end is passed the centre bore of manipulator fixed disk 6 vertically downward and is exposed the pullover of lower end, and this lower end pullover has a trepanning of head that can entangle the piston rod 9 of central authority; Simultaneously in the centering rod outside, also be set with a compression spring 5 between the pullover and upper end fairlead in its lower end, if the lower end of pushing tow centering rod, then centering rod can move upward in fairlead, if pushing tow not, then centering rod under the effect of compression spring automatically withdrawal reset.During the dress tire, the manipulator pivoted arm 11 of tire forming vulcanizer stretches earlier and rotates to the precalculated position, catching tire base calvus 7 below its manipulator fixed disk 6 hanging tire base 8 be positioned at tire forming vulcanizer central authority directly over, along with manipulator descends, the head of its centering rod 4 is inserted in the head of center machinery piston rod 9, and then capsule 10 is realized accurate contraposition with the tire base, typing back calvus shrinks and separates with the tire base, manipulator rises, and centering portion is separated gradually, then adorns tire and finishes.

Claims

1, tire forming vulcanizer manipulator centralising device, by bracing frame (1), fairlead (3), centering rod (4), gland (2) and compression spring (5) are formed, it is characterized in that: umbrella frame frame shape bracing frame (1) is fixedly mounted on the fixed disk (6) of tire forming vulcanizer manipulator, the bracing frame center is coaxial with the fixed disk central vertical, connecting vertically downward a fairlead (3) in the bracing frame center fixation, in the fairlead again suit centering rod (4), gland (2) is equipped with in the centering rod upper end, the centering rod lower end is passed the centre bore of manipulator fixed disk (6) vertically downward and is exposed the pullover of lower end, the pullover center of this lower end has the trepanning that can entangle central authority piston rod (9) head, simultaneously, in centering rod outside, be set with one in its lower end between pullover and the upper end fairlead and compress spring (5).
