Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical equipment of shock absorber manufacturing process, concretely relates to shock absorber connecting rod end thread oiling device. BACKGROUND

[0002] The end of shock absorber connecting rod is processed with thread and is used for connecting with the vehicle body. The thread of the end of shock absorber connecting rod is easy to rust due to long-term exposure to the external environment. Therefore, rust-proof treatment is needed. Since the thread head cannot be plated, the surface is usually oiled to prevent rusting of the thread of the end of connecting rod and ensure the quality of the shock absorber.

[0003] The existing oiling process usually uses brushes, rags, sprayers and other tools to apply lubricating oil to the thread of the shock absorber connecting rod. The whole process is operated manually. It is not possible to complete the operation in one step during the oiling process. The shock absorber connecting rod needs to be rotated to complete the oiling of the thread of the shock absorber connecting rod. The operation is relatively troublesome and the work efficiency is low. At the same time, due to the complex structure of the thread, the oiling may not be in place and the oil may accumulate, resulting in uneven distribution of the oil and incomplete rust prevention in the area with insufficient oil. In addition, only a thin layer of oil is needed on the surface of the thread of the shock absorber connecting rod. However, the amount of oil applied by the traditional manual application method cannot be controlled, which may result in excessive oiling, which may be misjudged by the customer as a leakage of the shock absorber. Therefore, the excess oil on the surface of the thread of the shock absorber connecting rod needs to be removed after the oiling is completed. The whole process is time-consuming and labor-intensive, which also causes waste of oil. SUMMARY

[0004] In order to overcome the deficiencies in the prior art, the utility model provides a shock absorber connecting rod end thread oiling device, which can uniformly and appropriately oil the thread of the end of the shock absorber connecting rod, can avoid the problem of incomplete rust prevention caused by uneven oiling, and can avoid excessive oiling, can avoid waste of oil, save production cost, and avoid misjudgment by the customer as a leakage of the shock absorber.

[0009] 2) The elastic oil absorption layer in the oiling device for shock absorber connecting rod end thread can be deformed under the extrusion after contacting the thread at the end of the shock absorber connecting rod, so as to adhere to the surface of the thread structure, so that the oil on the shock absorber connecting rod thread after processing is uniformly distributed.

[0010] 3) During the processing of the oiling device for shock absorber connecting rod end thread, the elastic oil absorption layer on the surface of the clamping blocks is deformed after contacting the surface of the thread at the end of the shock absorber connecting rod, thereby wrapping the thread at the end of the shock absorber connecting rod and extruding and seeping the oil to apply the oil to the surface of the shock absorber connecting rod thread; when the elastic oil absorption layer restores the shape, the excess oil on the surface of the shock absorber is absorbed, so that the amount of oil on the surface of the shock absorber connecting rod thread after processing is small, which can avoid being misjudged by the customer as shock absorber oil leakage; at the same time, the processing cost is reduced and the oil waste is reduced.
