Abstract
Description
Technical Field
[0001] This utility model relates to the field of automated equipment technology, and in particular to a vehicle axle stabilizer bar tightening mechanism. Background Technology
[0002] A stabilizer bar, also known as a torsion bar spring, is a special auxiliary elastic element in a car's suspension system. Its function is to prevent the vehicle body from experiencing excessive roll angles and lateral angular vibrations when cornering, increase the overall roll stiffness of the vehicle, thereby preventing lateral rollover and improving the overall comfort and handling stability of the vehicle.
[0003] Currently, when assembling the stabilizer bar assembly, there is a lack of a dedicated tightening device for the bolts and nuts on the stabilizer bar ball joint. Therefore, the following problems have been found during the assembly process of the stabilizer bar: 1. Most existing fixtures are fixed on the worktable. After the workpiece is clamped, the ball head is tightened. However, since there are many product models of stabilizer bars, it is necessary to design fixtures with various structures to match the stabilizer bars. The versatility between fixtures is poor.
[0004] 2. Stabilizer bars are mostly cylindrical in shape, which makes them easy to slip out. The clamping method is not suitable for installing stabilizer bars with ball heads.
[0005] 3. The tightening method of stabilizer bars is mostly manual tightening. However, manual tightening often results in problems such as not tightening the nuts to the specified torque, missing tightening, or incorrectly installing other types of products on other products. The quality cannot be guaranteed and the production efficiency is low. Utility Model Content
