Description

Technical Field

[0001] The utility model relates to the field of cooling devices, in particular to a cooling device for a numerically controlled machine tool. Background Art

[0002] CNC machine tools are equipment for processing parts. Before processing, parts are usually preliminarily formed by male molds, and then further refined by CNC machine tools. The mold will heat up as a whole after use, so the mold needs to be cooled, and a mold cooling device will be used;

[0003] During the use of existing mold cooling equipment, some adopt water cooling for cooling. However, waste chips will enter the liquid along with the water cooling. Although the liquid will be collected, filtering the waste chips for a long time will cause the filter to be blocked, thereby reducing the filtering effect and affecting the subsequent continuous extraction of sufficient liquid for use.

[0004] In order to solve the above problems, the present application proposes a cooling device for a CNC machine tool. Utility Model Content

[0005] (I) Purpose of the utility model

[0009] A semicircular filter screen is fixedly installed inside the box body, and a rotating filter mechanism is rotatably arranged inside the box body;

[0010] A liquid discharge port is formed at the bottom of one side of the box body, and an extraction mechanism is connected to the liquid discharge port. When the extraction mechanism extracts liquid, it is transmitted to the rotating filtering mechanism.

[0011] Preferably, the rotary filtering mechanism includes a bucket tube and a rotating filter screen, the bucket tube is rotatably sleeved on the box body, the rotating filter screen is fixedly installed on the bucket tube, the bucket tube is provided with a leakage port located at the discharge end of the rotating filter screen, and the bucket tube is fixedly connected to a transmission gear through a rotating rod.

[0012] Preferably, a guide plate is fixedly mounted on the box body.

[0013] Preferably, the extraction mechanism includes an extraction pump, a bucket body, a hydraulic fan blade, a driving gear and a mounting shell, the bucket body is fixedly connected to the discharge port, the hydraulic fan blade is rotatably connected to the mounting rod through a rotating rod, and the mounting rod is fixedly connected to the inner wall of the bucket body, the mounting shell is fixedly installed on the box body, the transmission gear is located inside the box body, the bucket body and the mounting shell are rotatably sleeved with a transmission rod, one end of the transmission rod is transmitted to the rotating rod, and the other end of the transmission rod is transmitted to the transmission gear through the driving gear, and the liquid inlet end of the extraction pump is fixedly connected to the discharge port of the bucket body.

[0014] Preferably, the transmission rod and the rotating rod are fixedly provided with mutually transmitting bevel gears at their ends close to each other.

[0015] The above technical solution of the utility model has the following beneficial technical effects:

[0016] When the tool head is being processed, the waste chips are introduced into the box body by the liquid sprayed from the nozzle at the tool head. When they are scattered into the guide plate, they are diverted and the extraction pump extracts the liquid inside the box body. The extracted liquid acts on the hydraulic fan blades through the bucket body. The hydraulic fan blades rotate and rotate through the transmission rod, the driving gear and the transmission gear to drive the bucket tube to rotate. The bucket tube drives the rotating filter to rotate, and the waste chips filtered out of the semicircular filter can be moved. As the semicircular filter rotates, the semicircular filter is tilted and introduced into the leak of the bucket tube, and then enters the interior of the bucket tube. Since the bucket tube is tilted from one side to the other, it is conducive to the discharge of waste chips, thereby reducing the phenomenon of waste chips clogging the semicircular filter, which is conducive to continuous filtration, reduces the intensity of subsequent processing, and continuously provides sufficient liquid for the extraction pump. The liquid extracted by the vacuum pump is supplied to the nozzle at the tool head. BRIEF DESCRIPTION OF THE DRAWINGS
