Description

Technical Field

[0001] This utility model relates to the field of tire testing devices, specifically a zero-point positioning system for a tire dynamic balancing machine. Background Technology

[0002] As is well known, tires may have uneven weight distribution during manufacturing due to process and material factors. Currently, traditional tire dynamic balancing testing machines require rotating the tire at the testing position and uploading the acquired test data to an industrial control computer. However, the current testing starting point is random. Although it can detect the light and heavy points of the tire, it cannot systematically analyze the tire dynamic balancing machine test data and cannot meet the requirements for quality control improvement. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a tire dynamic balancing machine zero-point positioning system, which performs zero-point positioning on the tire and aligns the position of the barcode on the tire's appearance with the dynamic balancing zero-point position.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a zero-point positioning system for a tire dynamic balancing machine, comprising a tire scanning system, a tire lubrication system, a dynamic balancing testing machine, and a PLC electrical control system. The tire scanning system is installed directly above the tire lubrication system and is on the same axis as the center of the dynamic balancing testing machine. The tire scanning system has a bracket, and the scanning head is installed above the bracket, located at the center of the tire lubrication system. The tire lubrication system has conveyor rollers connected to conveyor roller motors via conveyor roller chains at both ends. Tire clamps are located on both sides of the conveyor rollers, and a lubrication roller is located in the middle of the conveyor rollers. The dynamic balancing testing machine has a main shaft zero point, a main shaft rotation motor on one side, and roller-loaded clamps on both sides. The detection data from the dynamic balancing testing machine is fed back through the PLC electrical control system.

[0005] The beneficial effects of this utility model are that, in the absence of a zero-point positioning function in the dynamic balancing testing machine, no major modifications to the dynamic balancing inspection equipment are required. It can keep the barcode position consistent with the zero-degree position of the testing machine spindle, and make the measurement data accurately correspond to the actual position of the internal half of the tire. This facilitates the analysis of products by process technicians and quality personnel, and improves product quality by using data analysis tools. Attached Figure Description

PLC electrical control system. Detailed Implementation

[0009] In the figure, this utility model includes a tire scanning system 1, a tire slippage system 2, a dynamic balancing machine 3, and a PLC electrical control system 4. The tire scanning system 1 is installed directly above the tire lubrication system 2 and is on the same axis as the center of the dynamic balancing machine 3. The tire scanning system 1 has a bracket 101, on which a scanning head 102 is fixed. The scanning head 102 is installed above the bracket 101 and located at the center of the tire lubrication system 2, and performs barcode recognition on the inlet tires. The tire lubrication system 2 includes a tire holding arm 205, a lubrication roller 204, a conveyor roller 201, a conveyor roller chain 202, and a conveyor roller motor 203. The conveyor roller motor 203 rotates and drives the conveyor roller chain 202 to rotate the tires. Roller 201 rotates to provide rotary lubrication for the inlet tire. The tire lubrication system 2 is equipped with a conveyor roller 201, which is connected to a conveyor roller motor 203 via conveyor roller chains 202 at both ends. Tire clamping arms 205 are located on both sides of the conveyor roller 201, and a lubrication roller 204 is located in the middle of the conveyor roller 201. The dynamic balancing machine 3 is equipped with a main shaft zero point 301, a main shaft rotation motor 303, and roller-supported arms 304. The main shaft rotation motor 303 is located on one side of the dynamic balancing machine 3, and roller-supported arms 304 are located on both sides. The detection data from the dynamic balancing machine 3 is fed back through a PLC electrical control system 4. The PLC electrical control system 4 includes a PLC module, detection switches, etc.

[0010] The spindle rotation motor 303 of the balancing testing machine 3 drives the spindle zero point 301 to rotate. After detecting the data of one tire A, the angle α between the spindle zero point 301 and the tire's center stop position 302 is fed back to the PLC electrical control system 4. The PLC electrical control system 4 makes a judgment and calculates the rotation time of the lubrication part according to the required rotation angle, and controls the next tire B. At this time, the next tire B is driven by the rotation of two conveyor roller motors 203 in the tire lubrication system 2, which drives the conveyor rollers 201. The lubrication roller 204 rises and is positioned before rotating. When the scanning head 102 detects the barcode, the PLC electrical control system 4 starts timing and rotation. After the timing ends, the conveyor roller motor 203 stops running. After the tire arm 205 sets the center, the tire stops rotating. At this time, the barcode of tire B is aligned with the zero point 301 of the main shaft of the dynamic balancing machine 3. The two conveyor roller motors 203 run in the same direction, and the conveyor roller 201 drives the tire to the roller arm 304 of the dynamic balancing machine 3. The tire barcode coincides with the zero point 301 of the main shaft of the dynamic balancing machine 3, realizing the rotation measurement starting with the tire barcode as the zero point.
