Problems solved by technology

Since one end of the guide rod extends into the corresponding pair of radial holes on the two fixed disks, and the two are in a sliding fit, the guide rod and the radial holes are in direct contact, and the contact area is large, resulting in greater frictional resistance
However, if the friction resistance is large, the guide rod and the radial hole are easy to wear
Once the guide rod and the radial hole are worn out, the fit gap between the two will increase, and it may even be unusable
Therefore, adopting the above-mentioned structure requires frequent replacement of the guide rod or the fixed plate, which not only requires a large amount of maintenance work, but also increases the production cost.

Embodiment Construction

[0011] As shown in Fig. 1, Fig. 2 and Fig. 3, the drum tile telescoping mechanism of the tire building machine of the present invention contains a main shaft 2, two fixed discs 1 and some strip tiles 4 and forming drum tiles 5. Wherein, the diameters of the two fixed discs 1 are the same, they are all fixed on the main shaft 2, and there is a space between them, which corresponds to the center distance of the strip tiles 4 . There are 12 radial holes evenly distributed on the outer circumference of the two fixed disks 1 , and there are 12 guide rods 8 between both ends of each strip tile 4 and the corresponding fixed disk 1 . The formed drum tiles 5 are fixed on the outside of the strip tiles 4 one by one. Screw holes are processed at both ends of the strip tiles 4. One end of the guide rod 8 is processed with external threads. Screw into the screw holes at both ends of the strip tile 4, so that the guide rod 8 is arranged radially along the strip tile 4. Linear motion ball b...

Abstract

The present invention discloses a tire molding machine drum watt telescopic mechanism which comprises a spindle, two fixed disks and a plurality of banding tiles and a molding drum watt. A space is between the two fixed disks and the two fixed disks are both fixed on the spindle. A radial hole is arranged equally on the outer circle. The banding tile is provided with an oriented rod on the inside of two ends. One end of the oriented rod is fixed on and connected with two ends of the banding tile, and the other end of the oriented rod slides and extends into the corresponding radial hole which is arranged on the fixed disk. A cylinder is arranged between the two fixed disks. And the cylinder is shape of cone. An axial stomata is arranged on the spindle and is communicated with a cylinder body intracavity. A piston is arranged in the cylinder body. A inside boss club is arranged on the same position of the banding tile inside. An inclined plane is arranged on the inside boss club. The inclined plane sliding cooperates with the cone-shaped cylinder body. A pullback spring is also connected with the outside of the banding tile. The present invention is characterized in that a linear motion ball bearing is arranged in the radial hole of the fixed disk; the oriented rod sliding cooperates with the radial hole by the linear motion ball bearing. Using the present invention can reduce maintenance workload and production cost. The present invention is suitable for manufacturing tires of motorcycle and bicycle.

Description

technical field [0001] The invention relates to a tire production equipment. Specifically, it is the drum tile telescoping mechanism on the tire building machine that is used to produce motorcycles and bicycle tires. Background technique [0002] At present, the drum shoe telescoping mechanism that is used to produce motorcycle and bicycle cover all is traditional mechanism. This traditional mechanism includes a main shaft, two fixed discs and some strip tiles and shaped drum tiles. Both fixed disks are fixed on the main shaft, and there is a distance between them, which is equivalent to the length of the strip tile. Radial holes are evenly distributed on the outer circumference of the two fixed disks, and guide rods are provided on the inside of both ends of each strip tile. Said guide rods are arranged radially along the strip-shaped tiles, one end of which is fixed on the inner surface of both ends of the strip-shaped tiles, and the other end extends into a pair of cor...
