AI Technical Summary
In complex integrated equipment, traditional manual lubrication methods are difficult to effectively lubricate guide rails in narrow and confined spaces, resulting in low maintenance efficiency and potentially causing abnormal wear and decreased motion accuracy of the guide rails.
An oil injection device was designed. By installing a block and internal oil passage on the slider and combining it with an oil delivery component, the lubricating medium is accurately delivered to the surface of the guide rail. Dynamic coverage is achieved by utilizing the relative movement between the slider and the guide rail, thus avoiding disassembly and maintenance of the equipment.
It achieves efficient lubrication of enclosed equipment, improves the service life of guide rails and sliders, and enables precise delivery of lubricating medium in confined spaces, thereby improving maintenance efficiency.

Description
TECHNICAL FIELD
[0001] The present application relates to the field of linear motion modules, in particular to an oil injection device and a linear module. BACKGROUND
[0002] In the field of linear motion module maintenance, the traditional lubrication method mainly relies on manual direct oil injection operation on the guide rail surface. The conventional method requires a technician to manually apply lubricating grease to the contact surface of the guide rail slider, and through the reciprocating motion of the slider and the guide rail, the oil gradually penetrates into the ball circulation system. This operation mode can be implemented in open equipment or contactable structures, but in the actual application scenario of complex integrated equipment, it exposes significant defects: as industrial equipment evolves towards compactness and modularity, the internal space layout of a large number of precision machines is increasingly compact, especially for large equipment using multi-axis linkage structure, the core motion components are often packaged in narrow and closed spaces. This structural characteristic makes it difficult for technicians to directly contact the guide rail slider assembly for routine lubrication, not only significantly reducing maintenance efficiency, but also possibly causing guide rail abnormal wear, motion precision decline, and other problems due to the inability to timely supplement lubricating medium.
