Description

Technical Field

[0001] The utility model relates to the technical field of vehicle balancing machines, specifically an automatic lead discharging mechanism for a balancing machine. Background Art

[0002] Uneven mass distribution of automobile tires will cause the vehicle to vibrate, thus affecting the safe driving performance of the automobile. In order to eliminate the vibration phenomenon, lead weights for counterweight need to be added to the rim to correct the imbalance of the tire. Most of the lead weights on the tire are of the inner pasting type, which can not only be firmly pasted to the rim, but also does not affect the beauty of the vehicle. At present, the method of manual counting is adopted to count the number of lead weights and determine the total weight of the lead weights according to the weight of each lead weight. When the weight of the lead weights required for tire counterweight is large, the method of manual counting not only has low efficiency, but also increases the possibility of counting errors, wasting time and increasing the labor intensity of workers. Content of the Utility Model

[0003] To solve the above problems, that is, the problems raised in the above background art, the utility model provides an automatic lead discharging mechanism for a balancing machine, which includes a front plate and a rear plate. A main hook and a sub-hook are installed between the front plate and the rear plate. A driving device is installed on the upper wall surface of the front plate, and the driving device is connected to the main hook. A guide plate and a support plate are also installed between the front plate and the rear plate. A lead bar is installed between the guide plate and the support plate. The main hook and the sub-hook are in contact with the lead bar. Photoelectric switches are installed on the guide plate and the support plate. An unlocking plate is installed on the lower wall surface of the rear plate.

[0004] Preferably, openings are formed on both the guide plate and the support plate, and the photoelectric switches are located at the formed openings.

[0005] Preferably, two cylindrical protrusions are provided on the unlocking plate.

[0006] Preferably, the positions of the two cylindrical protrusions on the unlocking plate respectively correspond to the positions of the main hook and the sub-hook.

[0007] Preferably, the main hook makes a reciprocating translational motion, and the translation stroke is 1.5 times the length of the lead block on the lead bar.

[0008] The beneficial technical effect of the utility model is that this device can automatically output lead blocks by electricity and determine the weight of the output lead blocks according to the number of turns of the driving device.

[0012] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0013] The present utility model provides an automatic lead discharging mechanism for a balancing machine, including a front plate 6 and a rear plate 7. A main hook 2 and a secondary hook 3 are installed between the front plate 6 and the rear plate 7. A driving device 1 is installed on the upper wall surface of the front plate 6, and the driving device 1 is connected to the main hook 2. A guide plate 4 and a support plate 5 are also installed between the front plate 6 and the rear plate 7. A lead strip 10 is installed between the guide plate 4 and the support plate 5. The main hook 2 and the secondary hook 3 are in contact with the lead strip 10. A photoelectric switch 9 is installed on the guide plate 4 and the support plate 5. An unlocking plate 8 is installed on the lower wall surface of the rear plate 7; openings are provided on both the guide plate 4 and the support plate 5, and the photoelectric switch 9 is located at the provided openings; two cylindrical protrusions are provided on the unlocking plate 8; the positions of the two cylindrical protrusions on the unlocking plate 8 respectively correspond to the positions of the main hook 2 and the secondary hook 3; the main hook 2 makes a reciprocating translational motion, and the translational stroke is 1.5 times the length of the lead block on the lead strip 10.

[0014] Working principle: The driving device 1 drives the main hook 2 to make a reciprocating translational motion. The translational stroke of the main hook 2 is 1.5 times the length of the lead block on the lead strip 10. In this way, every time the driving device 1 rotates one week, the hook head of the main hook 2 will slide into the gap between the two lead strips 10 along the surface of the lead strip 10 and continue to push the lead strip 10 upward. When the main hook 2 moves to the maximum stroke, the hook head of the secondary hook 3 also enters the same gap. At this time, when the driving device 1 continues to rotate, due to the action of the secondary hook 3, the situation that the lead strip 10 retreats when the main hook 2 returns is prevented. That is, every time the driving device 1 rotates one week, a lead block is pushed forward. In this way, the weight of the output lead block can be calculated by the number of turns of the driving device 1.

[0015] When stopping the output of lead blocks, the driving device 1 is turned off. At this time, the secondary hook 3 will automatically press into the gap between the two lead blocks, playing a function of preventing backward movement. If it is necessary to replace the unused lead bar, by pushing the unlocking plate 8 upward, the two protrusions on the unlocking plate 8 will push the main hook 2 and the secondary hook 3 upward, so that the hooks are disengaged from the lead bar 10. Due to the action of gravity, the lead bar 10 will slide down automatically.

[0016] When the automatic lead output mechanism is equipped with the lead bar 10, the lead bar 10 will block the square holes opened on the guide plate 4 and the support plate 5. When the lead bar 10 is used up, since there is no blockage at the openings opened on the guide plate 4 and the support plate 5, at this time, the photoelectric switch 9 will give a signal that the lead bar 10 is used up, which can play a role in reminding to replace the lead bar in time.

[0017] Although the present utility model has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various technical features mentioned in each embodiment can be combined in any way.
