Description

[Detailed Description of the Invention] The present invention relates to a separator that separates chips from cutting oil adhering to chips generated by cutting operations of a machine tool.

In particular, this invention cuts by the centrifugal force generated by the rotation of a basket that stores chips dropped from the input port of the separator and the vertical movement of an elevating plate fixed to an elevating shaft coaxial with the rotation axis of the basket. Concerning a centrifugal separator that separates powder and cutting oil. In this type of centrifugal separator, if the chips thrown into the basket concentrate locally and accumulate, the rotation of the basket becomes unstable, causing vibrations, and the basket screen may become clogged. For this reason, a satisfactory separation effect cannot be expected. The present invention provides a separator intended to eliminate these drawbacks.

Hereinafter, the present invention will be explained based on practical drawings.

Reference numeral 1 denotes a centrifugal separator having a main body 1A having an input port 1a for chips, an exit port 1b for chips separated by centrifugal force, and a recovery port 1c for cutting oil.
In A, a rotating basket 3 having a rotating shaft 2 and an elevating plate 5 provided on an elevating shaft 4 coaxial with the rotating shaft 2 move up and down inside the basket 3 when the basket 3 rotates, and move the basket 3 up and down. Chips and cutting oil are separated by centrifugal force generated during rotation.
When the lifting plate 5 ascends, the chips are discharged from the basket 3 toward the upper discharge port 1b, and the cutting oil is discharged through a screen 3a provided on the peripheral wall of the basket 3.
This separator has a centrifugal separation structure in which cutting oil is expelled by centrifugal force and is recovered from the recovery port 1c. The lifting plate 5 provides a new technology in the present invention. Projections 6 extending in the radial direction of the elevating plate 5 are arranged at equal intervals on the circumference of the elevating plate 5 of the present invention, so that the chips are locally transferred to the basket 3 from the input port 1a.
Even if the chips are dropped into the interior, the chips hit the protrusions 6 when the basket 3 rotates and the lifting plate 5 moves up and down, and the chips are evenly dispersed on the lifting plate 5, resulting in a separation effect between chips and cutting oil. It is possible to improve this and prevent clogging of the screen with chips.

[Brief explanation of the drawing]

Fig. 1 is a cross-sectional view of the separator of the present invention, and Fig. 2 is a projection provided on the lifting plate.

Claims (1)

[Scope of utility model registration request] The basket rotates with a rotating shaft, and the lifting plate provided on the lifting shaft coaxial with the rotating shaft moves up and down inside the basket when the basket rotates, and the centrifugal force generated during the rotation of the basket causes the basket to move up and down. In a centrifugal separator that separates chips from cutting oil by removing the cutting oil from a screen installed around it and expelling the chips from the top of the basket, a protrusion extending in the radial direction of the lifting plate is placed on the circumference of the lifting plate. A centrifugal separator characterized by multiple arranged at equal intervals.
