Description

Technical Field

[0001] This application relates to the technical field, and in particular to an oil collection hood for an oil bath feeder. Background Technology

[0002] As shown in the patent document with publication number CN205651158U, the hydraulic station of the oil bath feeder supplies oil to the feed pipe. The oil pressure pushes the push rod to pass the bar through the end of the feed pipe and through the oil collection hood to the CNC lathe. Since the bar was previously immersed in the feed pipe, its surface is covered with oil. When the bar is connected to the lathe spindle in the oil collection hood, it rotates at high speed under the drive of the CNC lathe. The oil film on its surface automatically flies off into the oil collection hood under the action of centrifugal force to achieve oil removal.

[0003] In related technologies, traditional oil collection hoods are relatively short in length, resulting in short oil detachment time and poor oil collection effect. Therefore, the above comparative case uses a brush to further wash the oil film off the bar stock.

[0004] However, the device cannot effectively filter the lubricating oil during the recovery process. When the oil bath feeder is running, the lubricating oil or coolant comes into direct contact with the mechanical parts, inevitably carrying in impurities such as metal shavings, dust, and sand. If these impurities are not filtered in time, they can easily cause damage during the bar stock conveying process.

[0005] Therefore, those skilled in the art have provided an oil collection hood for an oil bath feeder to solve the problems mentioned in the background art. Utility Model Content

[0015] By adopting the above technical solution, the oil on the surface of the bar stock can be brushed off when it passes through the brush body, so as to better clean the oil on the surface of the bar stock.

[0016] Preferably, a stabilizing ring is fixedly installed on the top of the filter frame, and the stabilizing ring is sleeved on the surface of the oil inlet pipe and slidably connected thereto;

[0017] By adopting the above technical solution, the stability of the filter frame can be maintained, and the filter frame can be prevented from shaking during oil filtration, which would affect the oil filtration effect.

[0023] By adopting the above technical solution, this device can be installed on the surface of the feeding pipe of the feeder, so that the device can recover the oil on the surface of the bar stock.

[0024] In summary, this application includes the following beneficial technical effects:

[0025] 1. The oil collection hood of this oil bath feeder, through the cooperation between the filtration mechanism and the brush washing parts, can collect and return the lubricating oil for recycling. When the lubricating oil enters the interior of the filtration mechanism, the activated carbon filter and the filter screen can filter the lubricating oil. The lubricating oil automatically flows out of the interior of the filter frame and is further filtered by the sponge filter plate.
