Description

Technical Field

[0001] The utility model relates to the technical field of tire quality inspection devices, in particular to an auxiliary operating device for tire appearance inspection. Background Art

[0002] As the only part of a car that comes into contact with the ground, the performance of automobile tires directly affects the car's driving safety. Therefore, before leaving the factory, automobile tires must undergo comprehensive quality inspections to ensure that the tires meet the specified requirements in terms of safety, performance, and durability, thereby ensuring driving safety and the normal operation of the vehicle. The safety performance index system for automobile tire inspection includes appearance quality. The so-called appearance quality refers to whether there are any visually visible structural defects on the outer surface of the tire. It is usually visually inspected by the operator. For example, the National Passenger Car Tire Quality Standard (GB9743-2024) specifically stipulates that "the appearance quality of the tire should not have defects that seriously affect the service life, such as delamination between components, sponginess, broken wire rings, severe wire ring pull-up, multiple cord breakage, folding of the inner tire cord, and rubber edge cord protrusions in the crown. If a flap is used, the flap should not be damaged or cracked." In current production, tire appearance quality inspections typically require operators to repeatedly manually move and flip the tires on the ground or on an operating platform to fully inspect the entire inner and outer treads. During the inspection process, operators also need to hold or operate necessary lighting fixtures for auxiliary illumination. This is not only labor-intensive and inefficient, and cannot meet the needs of industrialized tire production development, but also requires high coordination of operators' movements. The slightest negligence can easily lead to defects being missed, posing a significant safety hazard to tires leaving the factory. Therefore, it is necessary to research and develop auxiliary tooling and specialized equipment specifically for tire appearance inspections, improve existing tire appearance inspection methods, and meet the actual production needs of tire manufacturing.

[0012] The beneficial effect of the present utility model is that it provides an auxiliary operation device for tire appearance inspection, which utilizes a freely rotatable rotating roller to hang the inspection tire, and lifts the inspection tire to the inspection station height through a pneumatically controlled lifting frame. At the inspection station, the operator can easily rotate the inspection tire, and at the inspection station, the overall visual inspection of the inspection tire can be completed at one time only by rotating the inspection tire. During the entire operation process, there is no need to perform other other moving or flipping operations on the inspection tire.

At the same time, an upper travel switch 22 and a lower travel switch 23 corresponding to the limit block 12 are also provided. The upper travel switch 22 is provided at the lower part of the limit block 12, and the lower travel switch 23 is provided at the upper part of the limit block 12. Two rotating rollers 4 arranged horizontally and parallel to each other are connected and installed at the front side end of the lifting frame 3. The rotating roller 4 is supported by the structural beam 14, and one side end extends toward the inspection work area of ​​the operator. Limiting rings 15 are respectively provided at the front and rear ends of the rotating roller 4; the external lighting lamp 8 is provided at the upper part of the rotating roller 4, as shown Figure 3 and Figure 4 As shown, the base frame 1 is connected to the base frame 1 by a lamp pole, and the two internal lighting lamps 5 are correspondingly arranged between the two rotating rollers 4. Figure 4 As shown, it is fixedly connected to the structural beam 14; the driving cylinder 2 is vertically arranged, the cylinder sleeve is fixedly connected to the connecting plate 13, and the piston rod is directly fixedly connected to the lifting frame 3. The lifting frame 3 is balanced and mounted on the base frame 1 through the connection of the driving cylinder 2 and the matching connection between the vertical track groove 11 and the vertical track beam 21; the roller bed 10 is composed of a roller frame 6, a support seat 7 and a threaded rod 9, as shown Figure 2As shown, a strip hole is opened at the bottom of the support seat 7, and the strip hole corresponds to the ground bolt 17 to select the positioning and fixed installation of the support seat 7. The roller frame 6 has a roller surface composed of a roller combination, which is hingedly connected to the support seat 7, and a limited hole is opened on the side plate of the support seat 7. A group of positioning holes is opened at the corresponding position of the side plate of the roller frame 6. Flipping the roller frame 6 relative to the support seat 7 can make each of the positioning holes correspond to the limiting holes. Different positioning holes and limiting holes are connected and locked with each other by positioning pins 19 to set and adjust the angle A of the roller surface relative to the ground. The threaded rod 9 is horizontally arranged in the same direction as the strip hole opened on the support seat 7, one end is connected to the support seat 7 axially for limiting rotation, and the other end is equipped with a turn wheel 18. The rod body and the threaded sleeve 16 fixedly installed on the basic frame 1 correspond to each other. Turning the threaded rod 9 can push and pull the support seat 7 for reciprocating linear movement.

[0024] The auxiliary operation device for tire appearance inspection described in this embodiment is used to perform appearance inspection operations on tires. Before the inspection operation, according to the model and specifications of the tire 20 to be inspected, first rotate the threaded rod 9 by turning the turning wheel 18 to adjust the setting position of the roller bed 10. After confirming the position, tighten the ground bolts 17 to fix the support seat 7. The selected positioning holes of the flip roller frame 6 are connected to the corresponding limiting holes on the support seat 7 and the positioning pins 19 are inserted into the connected hollow to lock the connection. The inclination angle A of the roller surface on the roller frame 6 is set. At the same time, the two internal lighting lamps 5 are adjusted to the appropriate illumination angles, and then the inspection operation can be carried out. The specific operation method is: control the lifting frame 3 to descend to the tire loading position height, such as Figure 5 and Figure 7 As shown, the tire 20 to be inspected is rolled and pushed to the inspection work area, so that the side tread of the tire 20 is perpendicular to the rotating roller 4, and the tire hole is aligned with the rotating roller 4. Then, the upper part of the tire 20 is gently pushed to turn it over and hang on the rotating roller 4; then, the lifting frame 3 is controlled to be lifted to the inspection position height, as shown in FIG. Figure 6 and Figure 7 As shown, the inner and outer lights 5 and 8 are turned on, and the operator then begins to gently turn the inspection tire 20 so that it is guided by the rotating roller 4 to rotate. While turning, the operator visually inspects the inner and outer treads of the inspection tire 20 respectively under the illumination of a fixed light. During the inspection process, any quality defects found are marked and recorded on the inspection tire 20 at any time. After completing the comprehensive inspection of the inner and outer treads, the lifting frame 3 is lowered to the tire loading position. During the lowering process, the inspection tire 20 will fall on the roller bed 10 provided below the rotating roller 4, as shown in FIG. Figure 7As shown, the roller surface on the roller bed 10 will guide the bottom end of the inspection tire 20 to slide forward to the outside of the end of the rotating roller 4, so that the inspection tire 20 is hung on the rotating roller 4 in an inclined state. At this time, the operator only needs to lift the upper end of the inspection tire 20 and straighten the inspection tire 20 to unload it from the rotating roller 4, completing the inspection operation of the inspection tire 20. Finally, the inspection tire 20 after the inspection is completed is rolled out of the inspection work area. During the entire inspection operation, the operator does not need to lift or move the inspection tire 20 off the ground. The operation process is simple and the labor intensity is low. It can fully achieve the purpose of the utility model and solve the problems of the existing technology.
