Description

Technical Field

[0001] This utility model belongs to the field of shock absorber assembly and production, and specifically relates to a shock absorber cylinder spin-on oiling device. Background Technology

[0002] In the traditional spin-on lubrication process for shock absorber cylinders, workers typically use a handheld spray gun to repeatedly spray the lubricant onto the cylinder bores, or fix the cylinder to a rotating table and spray while rotating. However, these methods have many problems.

[0003] Because the nozzle angle is fixed, when processing long tubular workpieces, the area near the nozzle receives sufficient oil, while the area further away tends to have insufficient coverage, making it difficult to guarantee uniform coating quality. Furthermore, when using single-point spraying, a large amount of oil is sprayed directly onto the surface of the workpiece, causing a bounce, and some oil mist also dissipates into the air, resulting in an effective oil utilization rate that is typically less than 60%.

[0004] Therefore, the above issues urgently need to be addressed. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a spin-on oiling device for shock absorber cylinders. The device achieves automated spin-on oiling through a rotating oiling component, which significantly shortens the production cycle and is suitable for mass production. At the same time, it reduces human error, ensures the consistency of the lubrication layer of each product, and improves product reliability. Furthermore, it provides precise oil control to reduce waste and lowers production costs in the long term.

[0006] Technical Solution: To achieve the above objectives, this utility model provides a shock absorber cylinder spin-on oiling device, including a frame, a platform, a cylinder placement seat, a lifting assembly, and a rotary oiling assembly; the platform is located in the middle of the frame; the cylinder placement seat is located on the platform; the lifting assembly is located on the platform and is situated on one side of the cylinder placement seat; the rotary oiling assembly is located on the lifting assembly and is situated directly above the cylinder placement seat; the rotary oiling assembly includes a mounting plate, an oil storage chamber, a rotary motor, a rotary spindle, several nozzles, and a cover; the mounting plate is located on the rotary oiling assembly and is driven by the rotary oiling assembly to move up and down; the oil storage chamber is located on the mounting plate; the rotary motor is located above the oil storage chamber; the upper end of the rotary spindle is connected to the output end of the rotary motor, and the lower end passes through the oil storage chamber and the mounting plate; the nozzles are located on the lower circumferential surface of the rotary spindle; the cover is located on the lower surface of the mounting plate. The rotary oiling assembly is designed to ensure that the oil is evenly sprayed onto the cylinder surface. The rotation of the spindle allows the nozzle to cover the inside of the cylinder from all angles, ensuring uniform oil distribution and effectively reducing cylinder wear and corrosion. By controlling the amount of oil in the reservoir and the spray pressure of the nozzle, the amount of oil applied can be precisely controlled, avoiding oil waste and ensuring the oiling effect. At the same time, compared with manual coating, the automated design of the rotary oiling assembly can significantly shorten the production cycle and is suitable for mass production.

[0007] Furthermore, the lifting assembly includes a set of guide columns and a cylinder; the guide columns are erected on the platform; the cylinder is located at the upper end of the guide columns, and its output end is connected to the mounting plate; the mounting plate is passed through by the guide columns and can move up and down along the axial direction of the guide columns. The use of the cylinder enables precise lifting control of the mounting plate. The output end of the cylinder is connected to the mounting plate, and by controlling the extension and retraction of the cylinder, the lifting height of the mounting plate can be accurately controlled.

[0008] Furthermore, the rotating spindle has several oil passage holes on its peripheral surface within the oil reservoir; the rotating spindle also has a passage connecting the oil passage holes to the nozzle. The design of the oil passage holes and the passage within the rotating spindle allows the oil in the oil reservoir to enter the rotating spindle through the oil passage holes and eventually reach the nozzle; when the rotating spindle rotates, the oil is sprayed out through the nozzle, completing the oiling operation on the cylinder body to be coated.

[0009] Furthermore, the oil reservoir is provided with an oil inlet. The oil inlet provides a channel for oil to enter the oil reservoir, allowing hydraulic oil to be quickly replenished into the reservoir, ensuring sufficient oil to maintain normal operating pressure and flow.

[0010] Furthermore, the mounting plate is also equipped with a shut-off valve; the shut-off valve is connected to the oil inlet of the oil storage chamber. The shut-off valve is used to control the flow rate and speed of oil entering the oil storage chamber, achieving precise oil control and reducing production costs.

[0011] Furthermore, the cross-sectional area of ​​the cap is slightly larger than the cross-sectional area of ​​the cylinder body to be coated. During the oiling process, the cap covers the upper surface of the cylinder body to be coated, preventing oil splashing and environmental pollution.

[0012] Furthermore, the bottom of the frame is equipped with several casters. The casters allow the frame to be repositioned along with the production line, facilitating flexible production line arrangement.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0014] 1. This utility model provides a shock absorber cylinder spin-on oiling device, which realizes automated rotary oiling through a rotary oiling assembly, greatly shortening the production cycle and making it suitable for mass production.

[0015] 2. This utility model provides a spin-on oiling device for shock absorber cylinders, which reduces human error, ensures the consistency of the lubrication layer for each product, and improves product reliability; moreover, precise oil control reduces waste and lowers production costs in the long term.
