Four-wheel alignment refers to adjusting the toe value of the vehicle's four wheels to ensure driving safety. In automobile production, four-wheel alignment equipment is commonly used to test and adjust the toe value of the vehicle's four wheels to ensure the vehicle travels straight on the road. During the adjustment process, the operator places an angle meter behind the steering wheel. When the angle meter value is within the detection range, the operator pulls the "roller rotation measurement switch" (switch). The equipment's roller rotates the vehicle's four wheels, and the equipment's laser sensor begins collecting toe value data. After adjusting the toe value to within the acceptable range, the operator uses an NR wrench (New Rapid wrench, pneumatic wrench) to tighten the suspension mounting nuts.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0032] Vehicle inspection line equipment is used to test vehicle performance data, adjust the four-wheel balance, and headlight data to ensure normal performance. Four-wheel alignment refers to adjusting the toe-in values ​​of the vehicle's four wheels to ensure driving safety. In automobile production, four-wheel alignment equipment is commonly used to test and adjust the toe-in values ​​of the vehicle's four wheels to ensure the vehicle travels straight on the road. During the adjustment operation, the operator places the angle meter behind the steering wheel. When the angle counter value is within the detection range, they reach out and pull the "Roller Rotation Measurement SW" button. The equipment roller rotates the vehicle's four wheels, and the equipment's laser sensor begins collecting toe-in data. After adjusting the toe-in value to within the acceptable range, the operator uses the NR wrench to tighten the suspension fixing nut. The NR wrench's auxiliary mobile bracket swings with the operation. However, due to the excessive force on the axle pin on the NR wrench auxiliary mobile bracket, coupled with the increased swing frequency of the NR wrench as vehicle production increases, the axle pin is prone to fatigue and breakage, affecting normal production.

[0033] After careful research by the applicant, it was found that the NR wrench bracket weighed 80kg, the NR wrench was used too frequently, and was subject to impact forces generated by swinging and vibration during use. The axle pin was only connected to the fixed shaft at the bottom, which made the bottom of the axle pin prone to breakage. After the axle pin broke, normal production was seriously affected, mainly in the following aspects:

[0034] ① Production: The wrench telescopic cylinder and bracket in-situ sensor could not sense the in-situ position, causing abnormal alarms on the equipment and resulting in 5 line stoppages per year;

[0035] ② Working hours: After the wrench axle pin breaks, the spare part needs to be replaced for 2 hours / time x 3 people / time x 5 times / year = 30 hours / year; the engineering hours consumed by the vehicle re-passing the functional line due to the broken axle pin are: 120 units / time x 8 minutes / unit x 6 people x 5 times / year = 8 hours / year; the maintenance and disassembly labor hours are: 1 time / year x 4 hours / piece x 4 pieces / year = 16 hours / year;

[0036] ③ Cost: Spare pin ordering cost: 8,000 yuan / pin, 8,000 yuan / pin x 5 times / year = 40,000 yuan / year; Maintenance cost: 2,800 yuan / pin x 4 pins / year = 11,200 yuan / year;

[0037] ④ Safety and health: When the axle pin breaks during use, the bracket will fall and hit the operator, resulting in 5 frightening incidents per year;

[0038] ⑤ Equipment life: The wrench auxiliary bracket fixes the shaft pin under great force, which affects the service life cycle of the shaft pin, and the average pin breakage is 5 times / year.

[0039] The main purpose of the utility model is to provide a wrench-assisted mobile bracket for four-wheel alignment equipment to solve the problem of how to avoid the breakage of an axle pin.
