Problems solved by technology

The prior art of this type of typical tire support and expansion mechanism has an extremely complex structure, and the operation is not stable enough. When the screw drives the screw nut to run at a constant speed, the running speeds of the tire support shafts driven by the screw nut are different at different positions. , leading to poor controllability; secondly, the driving power is far away from the tire support shaft operating head, which also increases the difficulty of accurate control of the tire support shaft operating position

Embodiment Construction

[0007] Figure 1 and figure 2 As shown, the X-ray tire inspection machine mainly includes a tire transmission part 1, a tire specification measurement part 2, a tire centering part 3, a tire expansion mechanism part 4, and an X-ray and imaging system part. In the figure, the X-ray and imaging system Some parts are omitted to fully demonstrate the tire expansion mechanism of this support. The X-ray tire inspection machine of the present invention supports the tire expansion mechanism, and the specific implementation structure of its main body is as follows: image 3 As shown, the mechanism is two sets of symmetrical worm and gear transmission parts driven coaxially. Two worm gears 6 are arranged symmetrically on both sides of the two worms 50, and the tire support arm 7 and the worm gear 6 assembled with the tire support shaft 8 are fixedly arranged and formed on the worm 50, which is also a tire support part symmetrical to the center line of the axis 5. Figure 1, figure 2 As...

Abstract

The invention relates to a tire spreading mechanism for an X-ray tire inspection machine. The main body of the tire spreading mechanism is two groups of symmetrical gear worm driving parts with coaxial driving, and the two groups of symmetrical gear worm driving parts are a gear worm driving pair, with the mutually opposite spiral directions of the worms; two worm wheels are symmetrically meshed on the two sides of the worm section of each group of gear worm driving part, a tire spreading arm provided with a tire spreading shaft is fixed with the worm wheels to form a tire spreading part, and each tire spreading part is arranged symmetrically on the two sides of the central line of the worms. The technical proposal solves the technical problems of complex structure, poor control performance and low control stationarity in the prior art, and has the advantages of simplified structure, steady and accurate control and operation.

Description

technical field [0001] The invention relates to a tire expanding mechanism in an X-ray tire testing machine. Background technique [0002] The X-ray tire inspection machine mainly includes a tire transmission part, a tire specification measurement part, a tire expansion mechanism part and an X-ray and imaging system part. The tire is brought into the detection area of ​​the X-ray and imaging system along the tire transmission part. The mechanism part implements the operation of stretching and expanding the tire so that the X-ray tube enters the inner space of the tire for imaging detection. The existing tire support and expansion mechanisms all use four tire support shafts and two tire expansion heads for each tire support shaft to complete tire positioning and edge opening operations on both sides, so the design core of the tire support and expansion mechanism is to require four tire support The axes always run synchronously on the same circle center. The more common supp...
