Description

A grinding machine cutting fluid iron chip filtering device

Technical Field

The invention relates to the technical field of cutting fluid filtration, and more specifically to a cutting fluid iron chip filtering device for a grinding machine tool.

Background Art

Cutting fluid is a liquid that plays a role in cooling, lubricating and cleaning during the metal processing process. It is widely used in the metal processing industry to provide the necessary lubrication and cooling protection for the machine tool grinding process. It also helps to extend the tool life and improve the processing quality. It has good lubricity and cooling properties and can effectively reduce friction and heat accumulation during cutting.

Traditional cutting fluid filtration devices for grinding machine tools usually use a filter screen to filter iron chips in the cutting fluid. During the filtration process, as the amount of cutting fluid filtered increases, the iron chips will gradually accumulate on the filter medium, requiring manual cleaning before continued filtration. In addition, the iron chips generated by cutting vary in size, and the existing filtration method lacks the operation of classified filtration, resulting in inadequate filtration. Small-volume iron chips can easily pass through the pores or tiny gaps of the filter medium during filtration and cannot be effectively intercepted, resulting in inadequate filtration.

The working principle of the second embodiment of the present invention is as follows: in the initial state, the rotating ring 7 between the two adjacent partitions 9 corresponding to each rotating ring 7 is connected to the discharge port 5, the feed pipe 6 is connected to the cutting fluid pipe to be filtered of the external grinding machine tool, the cutting fluid to be filtered is introduced into the work frame 1 through the feed pipe 6, and the cutting fluid to be filtered passes through each group of rotating rings 7 from the inside to the outside in turn, so as to realize screening and filtering of iron chips of different volumes in the cutting fluid.

After filtering for a period of time, by controlling the first electric push rod 25 to extend a specified length, the T-shaped plate 42 on the sliding member 23 is driven to slide synchronously along the slide groove 18. During this process, the guide ball 30 is slidably set on the guide rod 26, and each group of reset springs 35 is in a normal state. Each group of toothed plates 47 drives the corresponding second gear 19 to rotate, and drives the corresponding first gear 16 to rotate through the rotating shaft 15, thereby driving each group of rotating rings 7 to rotate synchronously by a specified angle, thereby realizing the replacement of the filtering position, preventing the cutting fluid to be filtered from working at the same position of the rotating ring 7, resulting in iron filings accumulation, so that the smaller iron filings in the cutting fluid to be filtered that is subsequently introduced remain in the unmatched rotating ring 7, reducing the effect of subsequent separation of iron filings of different volumes.

When the T-shaped plate 42 slides against an inner wall of the slide groove 18, the first pressure sensor 65 transmits a signal to the controller 67, and the controller 67 controls the first electric push rod 25 to stop, and at the same time controls the electromagnetic suction cup 62 to be electrically attracted to the iron block 63, so that the guide member 50 moves along the corresponding installation groove 49 on the vertical plate 37 toward the electromagnetic suction cup 62, and the corresponding connecting spring 64 is compressed. During the movement of the guide member 50, the ball head 60 is conveniently located on the second horizontal plate 54 from the initial state of being located on the first horizontal plate 52. Under the action of gravity, each group of tooth plates 47 descends along the corresponding fixed frame 38, so that the tooth plate 47 is disengaged from the corresponding second gear 19; at the same time, the second electric push rod 43 is controlled to extend to drive the rack 44 to descend, thereby driving the third gear 36 to rotate, so that the arc guide plate 27 rotates a specified angle.

In order to prevent the rotating component 2 from rotating after the tooth plate 47 is separated from the corresponding second gear 19, a ratchet is fixedly installed on the side of the rotating shaft 15, and a pawl and an arc spring are installed at the corresponding position on the side of the side cover 3 to form a ratchet and pawl assembly, so that each group of rotating rings 7 can only rotate in one direction.

The first electric push rod 25 is controlled to retract, driving the sliding member 23 to move in the opposite direction away from the electromagnetic suction cup 62. At this time, the tooth plate 47 and the corresponding second gear 19 are in a disengaged state. During the movement of the sliding member 23, the guide ball 30 is slidably set on the guide rod 26, and through the arc guide plate 27, in cooperation with the corresponding return spring 35, the scraper 32 on the scraper 12 is pressed to slide in and out of the working frame 1, and the corresponding iron filings between the two adjacent partitions 9 are scraped out from the working frame 1, and discharged and collected through the corresponding blanking channel 69. The ratchet pawl assembly is used to ensure that the position state of the rotating component 2 does not change during the scraping process.

When the second pressure sensor 66 on the T-shaped plate 42 abuts against the other opposite inner wall of the slide groove 18, the signal is transmitted to the controller 67. The controller 67 controls the first electric push rod 25 to stop, and controls the second electric push rod 43 to rise, shrink and reset, thereby driving the guide rod 26 to rotate in the opposite direction and reset, so that the arc guide plate 27 rotates downward, and at the same time controls the electromagnetic suction cup 62 to lose power, and drives the guide member 50 to slide and reset under the elastic reset force of the connecting spring 64, so that the ball head 60 is reset to the initial state of contact with the first cross plate 52. During this process, the tooth plate 47 rises along the fixed frame 38 to engage with the corresponding second gear 19.
