Description

Technical Field

[0001] The utility model relates to the technical field of broaching machine equipment, in particular to a self-lubricating component of a vertical broaching machine. Background Art

[0002] A broaching machine is a machine tool that uses a broach as a tool to process through holes, planes, and formed surfaces of workpieces. Broaching can achieve high dimensional accuracy and low surface roughness, with high productivity, and is suitable for batch mass production. Most broaching machines only have the broach as the main motion for linear broaching, without feed motion. During the operation of the broaching machine, the broach is mainly driven by the slider to make reciprocating motion in the slideway. The sliding contact wall of the slider and the slideway generates sliding friction. Therefore, in order to reduce wear and prevent rust, as well as for later use and maintenance, it is necessary to regularly apply lubricating oil to the sliding interface to ensure smooth operation of the broach. However, the current lubrication method has the following defects:

[0003] 1. At present, applying lubricating oil usually requires manual shutdown and the broaching machine needs to be stopped. The degree of automation is low and it will also affect production.

[0004] 2. At present, there are also oil filling holes opened in the slideway to inject lubricating oil, and self-lubrication is achieved through the reciprocating motion of the slider. However, this method of oil filling is always ongoing, and it is easy to over-inject oil, which not only wastes lubricating oil, but also easily overflows and is contaminated with dust due to excessive lubricating oil.

[0005] For this reason, we propose a self-lubricating component of a vertical broaching machine to solve the above problems. Utility Model Content

[0027] Working principle: When the utility model is in use, the slider reciprocates on the slide. When the slider moves to the boss, the groove wheel is lifted up by force and drives the piston to move up to the top of the oil channel. At this time, the lubricating oil cannot enter the slide through the oil channel. When the groove wheel leaves the boss, the groove wheel falls under the action of the spring, and then drives the piston to fall below the oil channel. At this time, the lubricating oil enters the slide from the oil channel for lubrication. The utility model does not require manual oiling and lubrication. During the movement of the slider, the lubricating oil falls into the slide, which can achieve self-lubrication and has a high degree of automation. The utility model adopts the cooperation of the groove wheel, the boss and the piston, so that the lubricating oil leaks into the slide at intervals, avoiding excessive oil filling, saving lubricating oil, and also avoiding the phenomenon of lubricating oil overflowing and being contaminated by dust.
