Description

Tire clamping device

Technical Field

The utility model relates to a tire grinding auxiliary machine, in particular to a tire clamping device.

Background

When the common tire is produced and delivered, the inner wall surface is attached with a release agent, and the anti-leakage layer needs to be sprayed and adhered to the inner wall of the corresponding ground surface of the tire in an upgrading process, so the release agent needs to be removed in the working procedure before processing. Automatic grinders on the market generally use the tire to rotate while simultaneously extending a grinding arm into the interior of the tire to remove the release agent from the rubber surface.

The tire needs to be fixed before polishing, and devices in the market use a stepping motor to mechanically control the stroke of a roller to clamp and position the tire. Because the tires are overlapped during storage or transportation, the width of the tread of some tires can be slightly changed, which causes the instability of tire clamping and influences the polishing effect.

The stroke limiter 460 may be a photoelectric sensor.

As shown in fig. 1 and 5, a tire pressing mechanism 500 is further disposed on the base 100, and the tire pressing mechanism 500 includes a roller set 510, a frame 520, a sliding table 530, a second cylinder 540, and a counterweight assembly 550. As shown in fig. 5, in the present embodiment, the roller group 510 is provided with two rotating rollers 511, and the roller group 510 is located above the driving roller group 200. Slide rails are arranged on two sides of the rack 520 and vertically extend along the height direction of the rack 520, and the sliding table 530 is slidably mounted on the slide rails of the rack 520, and the compression roller set 510 is mounted on the sliding table 530 and vertically ascends and descends along with the sliding table 530.

A driving wheel 551 is arranged on the upper part of the frame 520, and the counterweight assembly 550 and the sliding base are in driving connection through a chain 552 through the driving wheel 551, namely, the counterweight assembly 550 has upward pulling force on the sliding table 530. When the adjustment is carried out, the weight of the counterweight assembly 550 is equal to the sum of the weight of the sliding table 530 and the weight of each component such as the compression roller set 510 mounted on the sliding table 530, so that the left and right weight is balanced, and then the downward pull force on the sliding table 530 can be adjusted by only adjusting the air pressure of the second air cylinder 540. When the tire 600 is driven to roll by the driving roller group 200, the upward jumping amplitude of the tire 600 is reduced by the aid of the pressure roller group 510, air pressure of an air cylinder is downward pressure on the tire 600, and stability of the tire 600 during rolling is improved.

Further, since the tire 600 performs a certain range of side-to-side swinging within a controllable range during rolling, the pressing roller set 510 is connected to the sliding table 530 through a movable seat 560 in order to improve stability during tire pressing. In this embodiment, as shown in fig. 5, a rotating shaft 561 facing forward and backward in the axial direction is provided on the movable base 560, and the platen roller set 510 is connected to the rotating shaft, that is, the platen roller set 510 can swing left and right around the center axis of the rotating shaft 561. When the press roller group 510 presses the tire, the tire can swing left and right with a certain amplitude along with the tire 600, and the tire 600 is pressed well.
