Technical Field

The invention relates to the technical field of automobile part assembly tools, in particular to a tire quick resetting device.

Background

The emergency safety device for automobile tire burst and the tire pressure monitor are both safety devices which are arranged in the automobile tire and play a role in guaranteeing or early warning. The state has already made a regulation: GB7258-2017, JT/T1178.1-2018, JT/T1094-2016, JT/T325-2018 and JT/1178.2-2019, and the requirements are mandatory that after 9/1 of 2020, a newly-dispatched passenger car, a school bus, a dangerous chemical vehicle, an armor cash carrier, a heavy-duty truck and the like must be provided with a tire burst emergency safety device and a tire pressure monitor when the passenger car, the school bus, the hazardous chemical vehicle, the armor cash carrier, the heavy-duty truck and the like are dispatched from the factory. In addition, some domestic manufacturers of passenger vehicles, light trucks and heavy trucks are also beginning to install a tire burst emergency safety device and a tire pressure monitor at the front end in order to improve the safety of vehicle driving.

At present, automobile manufacturers install tire burst emergency safety devices and tire pressure monitors at the front end in batches, all use tire burst emergency safety device installation tools, will treat that operation tire bead pushes down, expose the rim recess, accomplish the assembly operation of tire burst emergency safety devices and tire pressure monitors, then utilize the resilience force of tire, let tire bead automatic re-setting, get into at last one and inflate the process for the tire. However, when the weather is cold or some tires with small resilience force are encountered, the condition that the tire bead of the tire cannot be reset can occur after the assembly operation of the tire burst emergency safety device and the tire pressure monitor is completed, and at the moment, the next inflation process cannot be completed. When the situation occurs, a worker on an assembly line generally takes out a tire which cannot be reset from a tool, forcibly falls the tire to the ground for many times to assist in completing the resetting of a tire bead, and then can enter the next tire inflation process.

At present, automobile manufacturers lack an auxiliary tool for completing the quick resetting of a tire lip at the front end of assembly after the assembly operation of a tire burst emergency safety device and a tire pressure monitor is completed. The manual whipping method is used for resetting the tire bead, and has the following defects: 1. the labor intensity of workers is high; 2. The rim is easy to scratch; 3. easily causes damage to the ground.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a tire quick reset device comprises a right base 5 and a left fixing frame 6, wherein a fixing frame with a structure similar to that of the left fixing frame 6 is arranged on one side, close to the left fixing frame 6, of the right base 5, a first roller 2 and a second roller 10 are arranged between the right base 5 and the left fixing frame 6, position regulators 8 are arranged at two ends of the first roller 2 and the second roller 10, each position regulator 8 comprises a regulator support 81, a fixing pin 82, an opening pin 83 and a regulator fixing hole 84, the first roller 2 and the second roller 10 are identical in structure, the first roller 2 consists of a fixing shaft 21 and a shaft sleeve 22, the shaft sleeve 22 is mounted on the surface of the fixing shaft 21 through a bearing, shaft fixing holes 23 are formed in two ends of the fixing shaft 21, and the fixing shaft 21 is fixed on the regulator support 81 through the shaft fixing holes 23 and the fixing pins 82;

a first inclined plane 1 and a second inclined plane 9 are fixedly connected between the right machine base 5 and the left fixing frame 6, and the first inclined plane 1 and the second inclined plane 9 are used for facilitating rolling-in and rolling-out of a tire 11 to be operated;

the center position of the right base 5 close to one side of the left fixed frame 6 is provided with an ejection disc 4, a pneumatic element is arranged in the right base 5, the pneumatic element can adopt an air cylinder, the ejection disc 4 is fixed at the working end of the pneumatic element, and the distance between the first rolling shaft 2 and the second rolling shaft 10 and the ejection disc 4 is adjusted to adapt to the resetting of tires with different diameters; the position regulator 8 is arranged on one side of the right base 5 close to the first inclined plane 1 and the second inclined plane 9 and one side of the left fixing frame 6 close to the first inclined plane 1 and the second inclined plane 9.

The surface of the ejecting disc 4 is provided with a protective rubber pad for preventing the rim from being scratched and contacted.

The bottom of one side of the right machine base 5 is also provided with a control pedal 3, the control pedal 3 is used for controlling the stretching and shrinking of a pneumatic element, and the ejection disc 4 can drive the rim to move towards one side of the left fixing frame 6, so that the purpose of quickly resetting the tire bead is realized.

Limiting plates 7 are fixedly connected to two sides of the top of the inner frame of the left fixing frame 6, and when the rim is ejected out by moving towards one side of the left fixing frame 6, the limiting plates 7 are used for limiting the position of a tire to be kept still, so that the purpose of quick resetting of a tire bead of the tire is achieved.

The use steps of the tire quick reset device comprise:

step 1, rolling a tire 11 to be operated with a non-reset tire bead into a region between a left fixing frame 6 and a right base 5 from a front first inclined plane 1, wherein the tire 11 to be operated can be automatically aligned with an ejection disc 4 due to the fact that shaft sleeves 22 which can freely rotate relative to a fixed shaft 21 are arranged on a first roller 2 and a second roller 10, and if the tire is not aligned with the ejection disc 4, adjusting position adjusters 8 at two ends of the first roller 2 and the second roller 10 to align the tire 11 to be operated with the ejection disc 4;

step 2, a control pedal 3 below the front surface of a right base 5 is stepped, a cylinder in the right base 5 is ejected leftwards to drive an ejection disc 4 to move leftwards, the ejection disc 4 is in contact with a rim of a tire 11 to be operated to drive the rim to move leftwards, and because two limiting plates 7 on the front side and the rear side above a left fixing frame 6 can limit the tire to move leftwards, only the rim in the tire moves leftwards, so that the tire bead of the unset tire is quickly reset;

and 3, when the tire bead which is not reset is reset, another control pedal 3 below the front surface of the right base 5 is stepped on, the cylinder in the right base 5 drives the ejection disc 4 to retract until the ejection disc 4 returns to the initial position, the control pedal 3 is released, the tire rolls out from the rear second inclined surface 9, and one-time tire resetting operation is completed.
