[0010] The filtering mechanism includes a liquid guide groove installed on one side of the support base provided with a chip guide hole. The liquid guide groove is divided into sub-grooves corresponding to the number of the spiral members by corresponding partitions. In each sub-groove, a filter member with a W-shaped longitudinal section can be installed to move up and down. The filter member includes a filter guiding part with a conical surface in the middle and correspondingly arranged directly below the discharging end of the spiral member, and an aggregate part in the shape of a bucket formed by bending and folding upwards from the end part of the filter guiding part. A plurality of filtrate holes penetrating through the upper and lower parts thereof are evenly distributed on the side wall of the filter guiding part.

[0011] The connection mechanism includes a support base fixedly installed in the sub-groove and correspondingly arranged directly below the filter member. At least one embedding hole is recessed downward on the upper end surface of the support base. A connection rod is installed to move up and down in the embedding hole through a corresponding elastic member. The other end of the connection rod not connected to the elastic member is connected to the filter member. A corresponding pressure gauge is fixedly connected to the bottom of the embedding hole in the middle, and the elastic member in the embedding hole is fixedly connected to the pressure gauge.

[0012] The filter member is arranged at an interval from the inner side wall of the sub-groove, and the inner side wall of the sub-groove forms a corresponding aggregate groove by welding an annular member with an L-shaped cross section. The aggregate groove is arranged below the gap between the filter member and the sub-groove, and the width of the aggregate groove is greater than the width of the gap between the filter member and the sub-groove.

[0013] The sub-grooves are communicated by arranging a space between the bottom of the partition and the bottom surface of the liquid guide groove, and both side edges of the partition are fixedly welded to the inner side wall of the liquid guide groove. The bottom surface of the liquid guide groove is inclined downward, and a liquid outlet is arranged at the inclined downward end thereof, and is connected to the cutting fluid collecting bucket through a corresponding liquid guide pipe and a liquid pumping pump.

[0014] On the other end of the support base where the mounting base is not provided, a vertical transverse plate is integrally formed and installed. A vertical plate is fixedly installed on the outer side surface of the vertical transverse plate corresponding to the position of the driving rod.

[0019] A plurality of bottom corner seats are arranged around the lower part of the support base, and adjustable bottom corners for adjusting the balance are fixedly installed on the bottom corner seats by screwing corresponding nuts.

[0020] Advantages of the present utility model:

[0021] 1) In the present utility model, a corresponding sub-groove is installed below the discharge end of the spiral member, and a filter member with a W-shaped longitudinal section is installed in the sub-groove corresponding to the spiral member. The metal iron filings in the mixed cutting fluid are conveyed onto the filter member, and the cutting fluid is filtered through the filtrate holes and collected in the liquid guiding groove. The metal iron filings are isolated and collected in the aggregate part along the inclined surface of the filter guiding part, achieving the effect of timely filtration.

[0022] However, due to the friction characteristics, the metal iron filings are prone to accumulate on the filter guiding part and block the filtrate holes. Therefore, in the present utility model, a connecting mechanism composed of a support base, an elastic member, and a connecting rod is used to move the filter member up and down. When the metal iron filings fall on the filter member, it will drive the filter member to vibrate up and down, thereby forming the effects of vibrating sieving and vibrating material guiding. In this way, filtration and material guiding are realized, further improving the practical effect.

[0023] 2) Although the present utility model can filter and collect metal iron filings and cutting fluid in real time, it is easy to cause the accumulation amount of metal iron filings to exceed the bearing capacity of the filter member after a long time, and it is necessary for personnel to observe the accumulation situation at any time and remove the metal iron filings in time, which increases the labor intensity. Therefore, in the present utility model, a corresponding pressure gauge is installed in the embedding hole of the support base, one end of the elastic member is fixedly connected to the pressure gauge, and the other end is connected to the filter member. As pressure is generated by the falling and collection of materials, the alarm upper limit value of the pressure gauge is set according to the material quantity, and personnel can process the metal iron filings in time according to the alarm, reducing the labor intensity.

[0024] 3) To ensure the up-and-down movement setting of the filter element, it needs to be spaced from the slotted part, which easily causes metal filings to fall into the liquid guide groove from the gap and mix with the filtered cutting fluid. Therefore, in the present utility model, a corresponding aggregate groove is formed by welding an annular part with an L-shaped cross-section below the filter element on the inner side wall of the liquid guide groove, so as to collect the metal filings falling from the gap, effectively prevent them from falling into the filtered cutting fluid again, and further ensure the filtering effect.

[0025] 4) In the present utility model, chip guide grooves are integrally formed on both sides of the support base, an installation seat is integrally formed above the end of the chip guide groove and the support base, and chip guide holes penetrating the installation seat are arranged at the position of the installation seat corresponding to the chip guide groove. Not only are the chip guide grooves communicated through the chip guide holes, enabling the chips to be smoothly and continuously discharged outwards, but also the discharge of the chips at the end part is promoted through the cooperation of the hole walls, effectively preventing blockage at the end part and improving the chip discharge effect.

[0026] 5) The installation seat integrally provided in the present utility model not only facilitates chip discharge but also helps to form sufficient support above the chip discharge mechanism for installing the column, and the contact surface for installing the column can be significantly increased, thereby improving the stability of the column support installation and ensuring the rigidity of the column.
