Description

Technical Field

[0001] The utility model relates to the technical field of boring and milling machines, in particular to a spindle extension guide structure for boring and milling machines. Background Art

[0002] A boring and milling machine is a device that combines the functions of a boring machine and a milling machine, making processing more efficient and accurate, greatly improving product quality and labor efficiency. The boring and milling machine can process products that need to be processed into corresponding sizes. After searching, the prior art (publication number: CN218696599U) records "a boring and milling machine with a waste collection function, including a base, a mounting shell and a lifting block, a waste collection structure is arranged inside the base, a reduction box is movably connected inside the mounting shell, a guide structure is arranged inside the lifting block, a spindle box is fixed on one side of the lifting block, and a spindle is installed on one end of the spindle box. The utility model can collect waste debris from the processing table by providing a waste collection structure. When it is used, a lot of debris will be generated, which may affect the processing. At this time, the fan is started to exhaust air, and the fan extracts the air inside the feed chamber through the air outlet to generate negative pressure. The negative pressure inside the feed chamber will suck the fine debris into it through the feed hole, and then the debris slides into the inside of the mesh box through the feed chamber. The mesh box can filter the debris. After use, the mesh box can be taken out for cleaning, thereby realizing the collection of waste debris from the processing table."

[0003] The spindle box involved in the boring and milling machine in the prior art has the function of guiding up and down movement, but when the spindle inside the spindle box is axially extended and retracted, the sliding guiding effect is generally achieved through a key block set in the bushing. Long-term axial movement and rotational movement of the spindle can easily lead to wear of the key block, resulting in deviation gap in the axial guiding movement, affecting the machining accuracy; secondly, the prior art also has the effect of guiding the movement of the spindle through a slider (with a linear shaft bearing inside) and a guide rod, but the reciprocating friction between the slider and the guide rod will cause oil sludge to appear on the outside of the guide rod, which is not convenient for timely cleaning. The metal impurities in the oil sludge will accelerate the wear of the bearing, thereby shortening the service life of the linear bearing. Utility Model Content
