[0002] Brake calipers are crucial automotive parts. With the rapid development of automobiles in recent years, the automotive market has increasingly demanded higher standards for these parts. Not only are component dimensional accuracy and other criteria required, but also cleanliness, such as product appearance, is also crucial. The brake caliper's piston dust cover is used to protect against impurities such as mud and sand. The lip of the piston dust cover forms an interference fit with the caliper body's shield groove, necessitating lubrication of the lip during assembly for quick assembly. Currently, the piston dust cover requires manual application of assembly fluid to the lip with a brush before assembly can proceed. During the application process, the piston dust cover accumulates and can contaminate other areas that do not require lubrication. This poses a risk of contamination of other components, such as the brake pads, during subsequent assembly. Utility Model Content

[0019] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0020] The structural diagram of the utility model is as follows Figure 1 As shown, the utility model is used for the lip lubrication process of the piston dust cover 5, comprising a fixing seat 1, a positioning head 3 and a lubricating oil-absorbing sponge 4;

[0021] Among them, the positioning head 3 is installed on the top of the fixing seat 1, and an annular groove is provided on the top surface of the positioning head 3. An annular lubricating oil-absorbing sponge 4 is arranged in the annular groove. A central through hole is provided in the fixing seat 1 as an oil pipeline. The bottom end of the oil pipeline is connected to the external oil storage device, and the top of the oil pipeline is connected to the annular groove of the positioning head 3. The assembly liquid of the oil storage device enters the annular groove after passing through the oil pipeline and is absorbed by the lubricating oil-absorbing sponge 4 to lubricate the lip of the piston dust cover 5; the piston dust cover 5 is placed on the positioning head 3, and the lip of the piston dust cover 5 is in contact with the lubricating oil-absorbing sponge 4.

[0022] The cross-sectional view of the present invention is as follows Figure 2 As shown, in the positioning head 3, a plurality of oil delivery grooves are opened between the top of the oil delivery pipeline and the annular groove, so that the oil delivery pipeline is connected with the annular groove through the oil delivery groove. The assembly liquid of the oil storage device passes through the oil delivery pipeline and then enters the annular groove through the plurality of oil delivery grooves, and is then absorbed by the lubricating oil-absorbing sponge 4.

[0023] An internal threaded hole is provided at the top of the fixing seat 1, which is fixedly connected to the lower end of the positioning head 3 through threaded fitting. A sealing ring 2 is provided between the fixing seat 1 and the positioning head 3 to prevent grease from overflowing.
