[0005] The existing filter has a simple structure and directly sets a filter screen for filtering. However, this design requires workers to frequently manually clean the chips accumulated on the filter screen, which not only increases the workload, but also makes the operation cumbersome and the work efficiency low.

[0027] Reference Figure 1-5 The utility model provides a filter for a lubrication system of a numerically controlled machine tool, which mainly comprises:

[0028] The main structure 100, such as Figure 1-2 The main structure 100 includes a filter box 101, a sealing cover 102 fixedly connected to the top of the filter box 101 by bolts, etc., and a first bearing plate 103 fixedly connected to the left inner wall of the filter box 101. An oil inlet pipe 104 is fixedly passed through the sealing cover 102, and an oil outlet pipe 105 is fixedly connected to the bottom of the filter box 101;

[0029] Filter plate 200, such as Figure 2 , the filter screen plate 200 is disposed in the filter box 101 and is fixedly connected to the top of the first bearing plate 103 by screws;

[0030] The impurity cleaning structure 300 is disposed on the left side of the filter box 101 and connected to the filter box 101, and is used to clean the impurities filtered out from the top of the filter screen plate 200;

[0031] The opening and closing structure 400 is disposed in the filter box 101 and connected to the right side of the filter screen plate 200;

[0032] The impurity receiving and discharging structure 500 is fixedly connected to the bottom of the opening and closing structure 400 , and the bottom end of the impurity receiving and discharging structure 500 is located outside the filter box 101 .

[0033] Specifically, Figure 3 The impurity cleaning structure 300 includes a scraper 301 movably fitted with the upper surface of the filter screen plate 200, a bracket 302 fixedly connected to the left outer wall of the filter box 101 by bolts, and a telescopic cylinder 303 fixedly connected to the bracket 302 by bolts. The piston end of the telescopic cylinder 303 is movably inserted into the filter box 101 and fixedly connected to the scraper 301 by bolts. When cleaning the accumulated chips of the filter screen plate 200, the telescopic cylinder 303 is started, and the piston end of the telescopic cylinder 303 drives the scraper 301 to move on the upper surface of the filter screen plate 200. During the movement, the accumulated chips can be pushed into the slag discharge frame 401, so that the filter screen plate 200 can be automatically cleaned without manual cleaning by the staff. It can not only reduce the workload of the staff, but also has high cleaning efficiency.

[0034] Specifically, Figure 4 The opening and closing structure 400 includes a slag discharge frame 401 fixedly connected to the right inner wall of the filter box 101, an opening and closing block 402 movably plugged into the inside of the slag discharge frame 401, and a lifting cylinder 403 fixedly connected to the top of the sealing cover 102 by bolts. The top piston end of the lifting cylinder 403 extends into the filter box 101 and is fixedly connected to the top of the opening and closing block 402 by bolts. The bottom of the slag discharge frame 401 facing the filter screen plate 200 is fixedly connected to a second bearing plate 404. The right side of the filter screen plate 200 is tightly fitted with the left side of the slag discharge frame 401 and is fixedly connected to the second bearing plate 404 by bolts. The upper surface of the filter screen plate 200 is flush with the upper surface of the slag discharge frame 401. The surrounding side of the opening and closing block 402 is connected to the slag discharge frame 401. A rubber ring 405 is provided between the inner walls of the frame 401. The rubber ring 405 is slidably connected to the inner wall of the slag discharge frame 401 and is fixedly connected to the opening and closing block 402, so as to improve the sealing between the slag discharge frame 401 and the opening and closing block 402. When the filter screen 200 is cleaned, the opening and closing block 402 is first driven upward by the lifting cylinder 403 to move the opening and closing block 402 to the top of the slag discharge frame 401, and the opening of the slag discharge frame 401 is exposed. Then, the scraper 301 is used to scrape the chips accumulated on the filter screen 200 into the slag discharge frame 401, and then the chips fall into the receiving box 501 through the slag discharge frame 401, so as to facilitate the collection of the chips. After the cleaning is completed, the opening and closing block 402 is reset by the lifting cylinder 403.

[0035] Specifically, Figure 5The impurity receiving and discharging structure 500 includes a receiving box 501 fixedly connected to the bottom of the slag discharge frame 401 by bolts and a slag discharge pipe 502 fixedly connected to the center of the bottom of the receiving box 501. The bottom end of the slag discharge pipe 502 passes through the filter box 101 and is installed with a valve. The internal space of the receiving box 501 is a trapezoidal groove structure with a larger upper part and a smaller lower part. The advantage of this arrangement is that after the chips fall from the slag discharge frame 401 into the receiving box 501, they can automatically gather at the mouth of the slag discharge pipe 502, thereby facilitating the chips to be discharged from the receiving box 501.

[0036] In summary, when in use, the lubricating oil enters the filter box 101 through the oil inlet pipe 104, and then, after being filtered by the filter screen plate 200, it is discharged through the oil outlet pipe 105. When the filter screen plate 200 needs to be cleaned, the filtering is stopped, and then the lifting cylinder 403 is turned on. The lifting cylinder 403 drives the opening and closing block 402 to move upward, so that the opening and closing block 402 moves to the top of the slag discharge frame 401, and the slag discharge frame 401 is exposed. Then, the telescopic cylinder 303 is started, and the piston end of the telescopic cylinder 303 drives the scraper 301 to move on the upper surface of the filter screen plate 200. During the movement, the accumulated chips can be pushed into the slag discharge frame 401, so that the filter screen plate 200 can be automatically cleaned without manual cleaning by the staff. Not only can the workload of the staff be reduced, but also the cleaning efficiency is high. The chips that fall into the slag discharge frame 401 fall into the receiving box 501 under the action of gravity, and are then discharged through the slag discharge pipe 502. After cleaning is completed, the opening and closing block 402 is reset by the lifting cylinder 403 to continue the filtering operation. The overall operation is simple, and the filter screen plate 200 can be cleaned quickly without easily affecting work efficiency.

[0037] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
