Abstract

The utility model discloses a transfer ring claw piece self-centering device, which comprises an optical axis arranged between adjacent claw pieces, wherein the left end of the optical axis is connected with the claw piece at the lower left side through a supporting seat, the right end of the optical axis is provided with a linear bearing which runs through, the linear bearing is arranged in a guide seat through a retaining ring, and the guide seat is connected with the claw piece at the lower right side; the spring pressing device is characterized in that movable hinge holes are formed in two sides of the guide seat, a guide pin shaft is sleeved in each movable hinge hole, a spring is sleeved on each guide pin shaft, a gasket used for pressing the spring is arranged at the end of each movable hinge hole, and the end parts of the two guide pin shafts are hinged to the claw piece on the lower right side. This from centering device sets up the guide pin axle that the cover was equipped with the spring in the both sides of guide holder, can make linear bearing reciprocate under the effect of spring and guide pin axle, effectively avoids when the claw piece atress is too big, and the optical axis damages linear bearing extrusion, stops equipment trouble, avoids the unplanned to shut down, guarantees that production goes on smoothly.

Description

Transfer ring claw piece self-centering device

Technical Field

The utility model relates to a tire design vulcanizer spare part, concretely relates to transmission ring claw piece is from centering device.

Background

The transfer ring claw piece self-centering device ensures that each claw piece is always kept in a circular shape at any position by radial expansion or contraction. At present, this from centering device is including locating the optical axis between the adjacent claw piece, and the left end of this optical axis passes through the supporting seat to be connected with the claw piece below the left side, and the right-hand member of this optical axis is equipped with and runs through a linear bearing, and this linear bearing installs in the guide holder, and this guide holder is connected with the claw piece below the right side. The self-centering device is simple in structure, easy to manufacture and low in manufacturing cost, but because the rubber tire is soft and the weight of the tire is large, the stress of each claw piece on the transmission ring is uneven, and the requirement on the processing precision of the claw pieces is high. In addition, because the linear bearing cannot move in the guide seat, when a certain claw piece is stressed greatly, the optical axis connected with the claw piece extrudes the linear bearing, so that the linear bearing is damaged, equipment failure is caused, and unplanned shutdown is caused.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model provides a transmission ring claw piece is from centering device, this from centering device set up the uide pin axle that the cover was equipped with the spring in the both sides of guide holder, can make linear bearing reciprocate under the effect of spring and uide pin axle, effectively avoid when the claw piece atress is too big, the optical axis damages linear bearing extrusion, stops equipment trouble, avoids the unplanned shutdown, guarantees that production goes on smoothly.

In order to achieve the purpose, the utility model discloses the technical scheme who takes:

the transfer ring claw piece self-centering device is the same as the prior structure in that: the optical axis is arranged between adjacent claw pieces, the left end of the optical axis is connected with the claw piece at the lower left side through a supporting seat, the right end of the optical axis penetrates through a linear bearing, the linear bearing is installed in a guide seat through a retaining ring, and the guide seat is connected with the claw piece at the lower right side; the difference is that: the movable hinge hole is formed in each of two sides of the guide seat, a guide pin shaft is sleeved in each movable hinge hole, a spring located in each movable hinge hole is sleeved on each guide pin shaft, a gasket used for pressing the spring is arranged at the end of each movable hinge hole, and the end portions of the two guide pin shafts are hinged to the claw piece on the lower right side.

Compared with the prior art, the utility model discloses the beneficial effect who has:

this from centering device sets up the guide pin axle that the cover was equipped with the spring in the both sides of guide holder, can make linear bearing reciprocate under the effect of spring and guide pin axle, effectively avoids when the claw piece atress is too big, and the optical axis damages linear bearing extrusion, stops equipment trouble, avoids the unplanned to shut down, guarantees that production goes on smoothly.

Detailed Description

As shown in fig. 1, the present invention provides a specific embodiment, a transfer ring claw piece self-centering device, which is the same as the existing structure: the optical axis 2 is arranged between adjacent claw pieces 1, the left end of the optical axis 2 is connected with the claw piece 1 on the lower left side through a supporting seat 3, a linear bearing 4 penetrates through the right end of the optical axis 2, the linear bearing 4 is installed in a guide seat 6 through a retaining ring 5, and the guide seat 6 is connected with the claw piece 1 on the lower right side; the difference is that: a movable hinge hole 7 has all been seted up to the both sides of guide holder 6, a guide pin axle 8 is established to movable hinge hole 7 endotheca, the cover is equipped with on the guide pin axle 8 is located spring 9 in the movable hinge hole 7, just the tip of movable hinge hole 7 is equipped with the gasket 10 that is used for pushing down spring 9, as shown in fig. 2, the tip of two guide pin axles articulates on the claw piece of the right below, and the embodiment sets up the screw thread end of guide pin axle and is fixed with claw piece 1, then guide holder 6 can be along the 1 luffing motion of claw piece of the right below, makes linear bearing 4 in it reciprocate simultaneously.

The utility model discloses during the use: install this self-centering device on the transfer ring as shown in fig. 3, claw piece 1 is in the inoperative state this moment, and spring 9 is in natural state, when waiting to the claw piece radial expansion as shown in fig. 4, if claw piece 1 grabs child atress too big, make optical axis 2 that this claw piece 1 is connected also the pressurized removal extrusion linear bearing 4, spring 9 compression this moment, linear bearing 4 can reciprocate under the effect of guide pin axle to effectively avoid linear bearing 4 to press the damage, also guarantee that all claw pieces on the transfer ring can still maintain on a circle.
