Disclosure of Invention

Aiming at the defects of the prior art, the invention aims to provide the mechanical hand tire touching device of the vulcanizing machine, which can improve the running stability of the vulcanizing machine, improve the vulcanizing efficiency and safety of the vulcanizing machine and reduce the use cost of customers.

The technical scheme includes that the tire touching device is arranged on the outer side of a claw piece of the manipulator, the difference is that the tire touching device comprises a tire touching plate installed through a swinging mechanism, the swinging mechanism comprises a swinging rod, the inner end of the swinging rod is hinged to a supporting plate of the claw piece, a stop lever for limiting the swinging angle of the swinging rod before tire grabbing is arranged on the supporting plate, and the outer end of the swinging rod is connected with the outer end of the tire touching plate through a hinge mechanism; the hinge mechanism comprises a front sleeve and a rear sleeve which are sleeved on the shaft pin, the front sleeve is connected with the swing rod, the rear sleeve is connected with the touch tire plate, a limiting part for limiting the upper and lower swing angles of the swing rod is arranged between the front sleeve and the rear sleeve, and a baffle plate which can be induced by a proximity switch arranged on the supporting plate when a tire is grabbed is arranged on the touch tire plate.

One optimized structure of locating part includes the circular arc recess and locates the circular arc fender ring of 1/4 in the circular arc recess.

Furthermore, the semicircular arc-shaped groove is formed in the front end face of the rear sleeve, and the 1/4 circular arc-shaped baffle ring is arranged on the rear end face of the front sleeve.

Conventionally, the proximity switch position corresponds to the position at which the manipulator grabs the tire in place.

The invention has the beneficial effects that:

the tire touching device of the mechanical hand of the vulcanizing machine has a simple mechanism, adopts a movable rotating point structure, and the tire touching plate of the mechanical hand can not extend to the inner side of the claw piece to damage the capsule when the mechanical hand grabs the tire, thereby improving the safety of the vulcanizing machine and reducing the use cost of customers.

Detailed Description

The technical solution of the present invention will be further explained with reference to the embodiments shown in the drawings.

The tire touching device for the manipulator of the vulcanizing machine comprises a tire touching device which is arranged on the outer side of a vertical claw piece 1 uniformly distributed on the circumference of the manipulator, wherein the tire touching device is provided with a tire touching plate 2 through a swinging mechanism, the tire touching plate 2 is in a ship shape with an upturned inner end (namely, one end close to the claw piece 1), and an upward strip-shaped baffle 5 is arranged on the tire touching plate 2, as shown in figures 1, 2 and 3.

The swing mechanism comprises a swing rod 3, a shaft sleeve is sleeved on the inner end of the swing rod 3 and connected with a supporting shaft 14, the supporting shaft 14 is installed on the front side face of a vertical supporting plate 4, the supporting plate 4 is radially installed on the outer side face of a claw piece 1, a stop lever 10 is arranged on the supporting plate 4 below the outer side of the supporting shaft 14, the stop lever 10 blocks the swing rod 3 which freely swings downwards on the position obliquely arranged on the outer lower side, the outer end of the swing rod 3 is connected with the outer end of a tire touching plate 2 through a hinge mechanism, a proximity switch 9 is installed on the supporting plate 4 above the swing rod 3 in an oblique mode, and the position of the proximity switch 9 corresponds to the position where a tire is grabbed by the claw piece 1 of a manipulator, as shown in fig. 1, fig. 2 and fig. 3.

The hinge mechanism comprises a front sleeve 7 and a rear sleeve 8 which are installed on a shaft pin 6 (a bolt and nut assembly), the front sleeve 7 is arranged at the outer end of the swing rod 3, the rear sleeve 8 is connected with the outer end of the tire plate 2, a limiting part for limiting the upper and lower swinging angles of the tire plate 2 around the shaft pin 6 is arranged between the front sleeve 7 and the rear sleeve 8, the limiting part comprises a semi-circular arc groove 11 and an 1/4 circular arc-shaped retaining ring 12 arranged in the semi-circular arc groove 11, the semi-circular arc groove 11 is arranged on the front end surface of the rear sleeve 8, the 1/4 circular arc-shaped retaining ring 12 is arranged on the rear end surface of the front sleeve 7, the tire plate 2 is contacted to a limiting position where one end of the semi-circular arc-shaped groove 11 is abutted against the 1/4 circular arc-shaped retaining ring 12 around the shaft pin 6 in the inward lower direction, and the position where the tire plate 2 is contacted by a manipulator before tire gripping is shown in fig. 1, 2 and fig. 3, As shown in fig. 4.

When a tire is grabbed, the claw sheet 1 descends towards the vulcanized tire 13, the upper end of the vulcanized tire 13 jacks up the inner end of the touch tire plate 2 to enable the inner end to swing inwards and upwards (the swing rod 3 is located at the position limited by the stop lever 10 at the moment), when the other end of the semi-arc-shaped groove 11 is abutted against the 1/4 arc-shaped stop ring 12, the touch tire plate 2 drives the swing rod 3 to swing outwards and upwards around the support shaft 14, the front end of the touch tire plate 2 slides outwards on the upper end of the vulcanized tire 13, the baffle 5 on the touch tire plate 2 moves upwards to the approach switch 9 along with the touch rod and senses the approach switch 9, the approach switch 9 is connected with a signal that the claw sheet 1 of the manipulator has grabbed the vulcanized tire 13 and controls the claw sheet 1 to stop descending, and in the tire grabbing process, the touch tire plate 2 is always located on the outer side of the claw sheet 1 and cannot extend to the inner side of the claw sheet 1 to damage a capsule, as shown in fig. 1.

The manipulator is when no child snatchs, pendulum rod 3 and touch child board 2 all lean on the dead weight downswing, and pendulum rod 3 is by pin 10 restriction oscillating position, touch child board 2 by in the semi-circular arc recess 11 with 1/4 arc keep off the interact of ring 12 and restriction oscillating position, touch baffle 5 and proximity switch 9 on the child board 2 and stagger, proximity switch 9 loses sensing signal.
