A vertical machining center water collecting device with filtering structure

Abstract

This utility model discloses a water collection device for a vertical machining center with a filtration structure, including a collection box. A ring-shaped filter screen is installed in the middle of the collection box. The ring-shaped filter screen is a ring-shaped transmission belt. A chip collection box is fixedly installed at one end of the collection box. By driving the ring-shaped filter screen to rotate, cutting fluid and iron chips flow above the ring-shaped filter screen through the chip discharge channel of the vertical machining center. Since the filter screen is in a continuous state of motion, the continuously transported cutting fluid and iron chips will move to different positions on the ring-shaped filter screen, which can prevent iron chips from accumulating in one position on the filter screen for a long time and reducing the filtration effect. By controlling the rotation of the rotating shaft, the first pulley at one end of the rotating shaft will be driven to rotate. The transmission belt drives the first pulley and the second pulley to rotate the brush roller. The brush roller can clean the surface of the ring-shaped filter screen under movement, further improving the continuous filtration effect of the cutting fluid.

Description

Technical Field

[0001] This utility model relates to the field of vertical machining center technology, specifically a water collection device for vertical machining centers with a filtration structure. Background Technology

[0002] A vertical machining center is a highly automated, multi-functional CNC machine tool equipped with a tool magazine and an automatic tool changer. During the machining process, cutting fluid is used to cool the workpiece and the cutting tool. The cutting fluid and metal chips flow into the cutting fluid collection box at the bottom through the flow channel, where they are filtered and separated by an oil-water separator to achieve the reuse of the cutting fluid.

[0003] Existing collection boxes are generally located at the bottom of vertical machining centers. A filter screen installed on the collection box is used to initially filter the cutting fluid. However, since the position of the filter screen is fixed, the cutting fluid and iron filings flowing from the cutting point of the vertical machining center fall into a specific position on the filter screen. When the filter screen is used to filter the cutting fluid and iron filings for a long time, it will cause blockage at this position, affecting the continuous filtration effect of the cutting fluid. Utility Model Content

[0004] The purpose of this invention is to provide a vertical machining center water collection device with a filtration structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vertical machining center water collection device with a filtration structure, comprising a collection box, a ring-shaped filter screen being driven and installed in the middle of the collection box, the ring-shaped filter screen being a ring-shaped transmission belt, a chip collection box being fixedly installed at one end of the collection box, and a feed inlet being opened at the end of the collection box corresponding to the top position of the chip collection box, the top of the feed inlet being tangentially contacted with the outer surface of the ring-shaped filter screen, and a brush roller being rotatably installed at the end of the collection box away from the chip collection box via a bearing, the brush roller being provided with brush cloth, the brush roller being positioned below the ring-shaped filter screen, and the brush roller being in contact with the lower surface of the ring-shaped filter screen.

[0006] As a further preferred embodiment of this technical solution, both ends of the collection box are rotatably mounted with rotating shafts via bearings, and both ends of the rotating shafts are fixedly mounted with positioning transmission wheels. The annular filter screen is driven between the four positioning transmission wheels on the two rotating shafts. A motor is fixedly mounted on one side of the collection box, corresponding to the position of one of the rotating shafts, and the output end of the motor is fixedly connected to one end of the rotating shaft via a shaft connector.

[0007] As a further preferred embodiment of this technical solution, the rotation direction of the brush roller is the same as the rotation direction of the ring filter screen.

[0008] As a further preferred embodiment of this technical solution, a first pulley is fixedly installed at one end of one of the rotating shafts, and a second pulley is fixedly installed at one end of the brush roller, with a transmission belt connecting the first pulley and the second pulley.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 3 As shown in this embodiment, a water collection device for a vertical machining center with a filtration structure includes a collection box 1. A ring-shaped filter screen 2 is mounted in the middle of the collection box 1. The ring-shaped filter screen 2 is a ring-shaped transmission belt. A chip collection box 3 is fixedly mounted at one end of the collection box 1. An inlet 4 is provided at the end of the collection box 1 corresponding to the top of the chip collection box 3. The top of the inlet 4 is tangentially contacting the outer surface of the ring-shaped filter screen 2. A brush roller 5 is rotatably mounted on the end of the collection box 1 away from the chip collection box 3 via a bearing. The brush roller 5 is provided with brush fabric and is positioned below the ring-shaped filter screen 2, contacting the lower surface of the ring-shaped filter screen 2, thus driving the ring-shaped filter screen 2 to move... Rotating like a conveyor belt, the cutting fluid and iron filings flow through the chip removal channel of the vertical machining center above the ring filter screen 2. Since the ring filter screen 2 is in continuous motion, the continuously conveyed cutting fluid and iron filings will move to different positions on the ring filter screen 2, which can prevent iron filings from accumulating in one position on the filter screen for a long time and reducing the filtration effect. At the same time, as the ring filter screen 2 moves, the iron filings on the ring filter screen 2 will enter the chip collection box 3 through the feed port 4 to collect the iron filings. The control drives the brush roller 5 to rotate, and the brush roller 5 can clean the surface of the ring filter screen 2 under movement, further improving the continuous filtration effect of the cutting fluid. The filtered cutting fluid will fall to the bottom of the collection box 1.

[0021] like Figures 1 to 3 As shown, both ends of the collection box 1 are rotatably mounted with rotating shafts 6 via bearings, and both ends of the rotating shafts 6 are fixedly mounted with positioning transmission wheels 7. The ring filter screen 2 is driven between the four positioning transmission wheels 7 on the two rotating shafts 6. A motor 8 is fixedly mounted on one side of the collection box 1, corresponding to one of the rotating shafts 6. The output end of the motor 8 is fixedly connected to one end of the rotating shaft 6 via a shaft connector.

[0022] The motor 8 drives one of the rotating shafts 6 to rotate, and the ring filter screen 2 transmits power between the four positioning transmission wheels 7 on the two rotating shafts 6, which in turn drives the other rotating shaft 6 to rotate, thereby driving the ring filter screen 2 to rotate.

[0023] like Figures 1 to 3 As shown, the rotation direction of the brush roller 5 is the same as the rotation direction of the ring filter screen 2.

[0024] As the ring filter 2 moves, the position of the brush roller 5, which is in contact with the ring filter 2, can be controlled to be pushed against the forward direction of the ring filter 2.

[0025] like Figures 1 to 3 As shown, a first pulley 9 is fixedly installed at one end of one of the rotating shafts 6, and a second pulley 10 is fixedly installed at one end of the brush roller 5. A transmission belt 11 is connected to drive the first pulley 9 and the second pulley 10.

[0026] Since both shafts 6 rotate, the first pulley 9 at one end of the shaft 6 will rotate, and the transmission belt 11 will drive the brush roller 5 to rotate through the transmission between the first pulley 9 and the second pulley 10.

[0027] like Figures 1 to 3 As shown, an air pipe 12 is fixedly installed in the middle of the collection box 1. The air pipe 12 is connected to the air outlet of the blower. Air holes 13 are equidistantly opened in the middle of the bottom end of the air pipe 12. The air pipe 12 is located in the middle of the ring filter screen 2. The air pipe 12 is located in a position that contacts the brush roller 5 earlier.

[0028] Air is blown into the air pipe 12 by the blower, and air will be released from the air hole 13 at the bottom of the air pipe 12. This air can blow out the iron filings blocking the filter holes of the ring filter 2, preventing the iron filings from clogging the filter holes of the ring filter 2.

[0029] like Figures 1 to 3 As shown, a plate filter screen 14 is fixedly installed at one end of the air pipe 12 near the chip collection box 3, and a liquid outlet pipe 15 is fixedly installed at one end of the collection box 1 near the plate filter screen 14.

[0030] After the ring filter 2 filters the cutting fluid, the plate filter 14 can filter the cutting fluid at the bottom of the collection tank 1 again, further improving the filtration effect of the cutting fluid at the bottom of the collection tank 1.

[0031] This utility model provides a vertical machining center water collection device with a filtration structure, the specific working principle of which is as follows:

[0032] When the device is in use, the motor 8 drives one of the rotating shafts 6 to rotate. The ring filter 2 transmits power between the four positioning transmission wheels 7 on the two rotating shafts 6, synchronously driving the other rotating shaft 6 to rotate, which in turn drives the ring filter 2 to rotate, similar to the principle of a conveyor belt. The cutting fluid and iron filings flow through the chip removal channel of the vertical machining center above the ring filter 2. Because the ring filter 2 is in continuous motion, the continuously transported cutting fluid and iron filings will move to different positions on the ring filter 2, preventing iron filings from accumulating in one place and reducing the filtration effect. Simultaneously, as the ring filter 2 moves, the iron filings on it will enter the chip collection box 3 through the feed inlet 4, achieving chip collection. Air is also blown into the air pipe 12 by a blower, and air exits from the air hole 13 at the bottom of the air pipe 12, which can purify the ring filter 2. Air is blown through the ring filter 2 to blow out the iron filings blocking the filter holes, preventing them from clogging the filter holes. Then, since both shafts 6 rotate, the first pulley 9 at one end of the shaft 6 will rotate. The transmission belt 11 drives the first pulley 9 and the second pulley 10 to rotate the brush roller 5. The brush roller 5 can clean the surface of the ring filter 2 under movement, further improving the continuous filtration effect of the cutting fluid. The filtered cutting fluid will fall to the bottom of the collection tank 1. With the continuous supply of cutting fluid, the cutting fluid will undergo further fine filtration in the device through the outlet pipe 15, achieving further fine filtration. Before supplying the cutting fluid in the collection tank 1, the cutting fluid at the bottom of the collection tank 1 can be filtered again through the plate filter 14, further improving the filtration effect of the cutting fluid at the bottom of the collection tank 1.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
