Description

Technical Field

[0001] The utility model relates to the technical field of glass processing equipment, in particular to a carriage integrating manual control and automatic control functions. Background Art

[0002] In order to meet various usage requirements of glass, it is often necessary to polish and edge grind the glass. At present, a relatively mature production method is to use a double-sided glass edging machine to grind the edges of the glass. A common double-sided glass edging machine generally includes a carriage mechanism for realizing the feed movement of the grinding wheel.

[0003] For the grinding wheel feed device of the existing double-sided glass edging machine, generally, the output end of a servo motor is directly connected to the sliding part of the carriage or connected through a speed reducer to realize the drive. Such a design method can realize the automatic feed of the grinding wheel. However, if an electrical fault occurs and the servo motor stops working, the carriage cannot be adjusted, resulting in the shutdown of the equipment, making the entire processing equipment unusable and further causing losses to the user. Moreover, due to the relatively precise and complex transmission system of the carriage, during long-term continuous processing, the continuous friction between the transmission structures (such as guide rails and lead screws) will cause wear and even damage to the machine parts, thereby reducing the working performance of the carriage and even shortening its service life.

[0004] Therefore, there is an urgent need in the prior art to invent a carriage mechanism that combines manual and automatic drive control functions and has a long service life. Summary of the Utility Model

Specifically, the guide rail is used as a transmission structure for realizing the feed of the slide plate 2. By arranging the first oil inlet passage 11 to deliver lubricating oil to the guide rail between the bottom plate 1 and the slide plate 2, an oil circuit system is formed between the matching guide rails, reducing friction and loss, and having functions such as rust prevention and oxidation prevention, ensuring that the guide rail transmission structure can still maintain high feed accuracy during long-term processing, thereby improving the working performance and service life of the equipment.
