Description

Technical Field

[0001] The utility model relates to the technical field of vehicle repair and maintenance, in particular to a rotating tire and a positioning device for a motorcycle tire dynamic balancing machine. Background Art

[0002] The wheel of a vehicle is composed of two parts: the tire and the wheel hub. During the processing, manufacturing and assembly process, the mass distribution may be uneven. When the wheel rotates at high speed, an unbalanced state will be formed, causing the steering lever to shake and the tire to wear unevenly, seriously affecting the service life of the tire and even causing safety hazards. Therefore, a balancing machine is needed to correct it. When the motorcycle balancing machine corrects the dynamic balance of the motorcycle tire, the motor directly drives the balancing machine spindle to drive the tire to rotate. Due to the low machining accuracy of the motorcycle balancing machine spindle, when the tire rotates, it will affect the tire dynamic balance measurement results. Utility Model Content

[0003] In order to solve the above problems, that is, to solve the problems raised by the above background technology, the utility model proposes a rotating tire and positioning device for a motorcycle tire dynamic balancing machine, including a support plate and a balancing machine main shaft, a rotating shaft is installed on the support plate, a motor connecting plate is installed on the rotating shaft, a cylinder and a motor are installed on the motor connecting plate, a rotating shaft is installed on the motor driving end, and the other end of the cylinder is installed on the balancing machine main box, an encoder, a tire and a locking sleeve are installed on the balancing machine main shaft, and the encoder is electrically connected to the cylinder through the balancing machine main body.

[0004] Preferably, the connection position between the cylinder and the motor connecting plate is located between the main shaft of the balancing machine and the rotating shaft.

[0005] Preferably, the outer edge surface of the rotating shaft is covered with a rubber anti-slip layer.

[0006] Preferably, a pair of shaft retaining springs are installed at both ends of the rotating shaft.

[0007] Preferably, the tire is located between the encoder and the locking sleeve.

[0008] The beneficial technical effect of the utility model is: it realizes the measurement method of the rotation of the motorcycle tire around the fixed main shaft of the balancing machine, that is, relying on the rolling bearing of the tire itself, the friction force is used to drive the tire installed on the main shaft of the dynamic balancing machine to rotate, and at the same time, the encoder installed on the main shaft of the balancing machine and performing synchronous rotation movement with the tire will use a motor with forward and reverse rotation and braking functions to position the measured tire imbalance position at a predetermined angular position, such as the 12 o'clock direction of the tire according to the measured tire imbalance position. In this way, it is only necessary to stick a lead block of the required weight at the 12 o'clock direction of the tire, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0013] The utility model proposes a rotating tire and positioning device for a motorcycle tire dynamic balancing machine, comprising a support plate 11 and a balancing machine main shaft 5, a rotating shaft 10 is installed on the support plate 11, a motor connecting plate 8 is installed on the rotating shaft 10, a cylinder 1 and a motor 7 are installed on the motor connecting plate 8, a rotating shaft 6 is installed on the driving end of the motor 7, the other end of the cylinder 1 is installed on the balancing machine main box, an encoder 3, a tire 2 and a locking sleeve 4 are installed on the balancing machine main shaft 5, the encoder 3 is electrically connected to the cylinder 1 through the balancing machine main body; the connection position between the cylinder 1 and the motor connecting plate 8 is located between the balancing machine main shaft 5 and the rotating shaft 6; the outer surface of the rotating shaft 6 is covered with a rubber anti-skid layer; a pair of shaft retaining springs 9 are installed at both ends of the rotating shaft 10; the tire 2 is located between the encoder 3 and the locking sleeve 4.

[0014] Working principle: first push the piston rod of cylinder 1 to the maximum stroke. During this process, cylinder 1 will drive the motor connecting plate 8 to rotate in the direction away from the balancing machine main shaft 5. After the piston rod is fully pushed out, install the tire 2 on the fixed balancing machine main shaft 5, use the locking sleeve 4 to lock the motorcycle tire to the balancing machine main shaft 5, and allow the encoder 3 to rotate with the tire 2. After locking the tire 2, the piston rod of cylinder 1 retracts. At this time, the rotating shaft 6 gradually approaches the outer surface of the motorcycle tire 2. When the rotating shaft 6 is tightly attached to the tire surface, the motor 7 is energized. At this time, the cylinder 1 is in a pressure-maintaining state. Due to the pressure of the rotating shaft 6, there is a constant friction force in size and direction between the rotating shaft 6 and the tire surface. When the motor 7 drives the rotating shaft 6 to rotate, the tire 2 will also rotate together. When a certain speed is reached, the encoder 3 will send a signal, so that The inlet and outlet of cylinder 1 are reversed, and the piston rod of cylinder 1 is pushed out to complete the separation of rotating shaft 6 and tire 2. At this time, tire 2 will continue to rotate 6 to 12 times due to inertia. During this period, the motorcycle tire dynamic balancing machine will measure the unbalanced position of tire 2, and due to the effect of damping, when the rotation speed of tire 2 is lower than the set value, encoder 3 will give an electrical signal. At this time, the piston rod of cylinder 1 will retract, and motor 7 will be started and reversed. When rotating shaft 6 gradually comes close to the outer surface of tire 2, since the rotation direction of the motor shaft is opposite to that of motorcycle tire 2, the rotation speed of motorcycle tire 2 will gradually decrease, and the braking function of motor 7 will be used to position the unbalanced position of tire 2 at a predetermined angle. After affixing lead blocks at the unbalanced position, fully extend the piston rod of cylinder 1, remove the locking sleeve 4, and then remove tire 2 from the main shaft 5 of the balancing machine.
