Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing cooling devices, and particularly relates to a cooling device for a numerical control machine tool. Background Technique

[0002] As a highly automated machine tool, a numerical control machine tool controls the movement and processing process of the machine tool through a computer to achieve precise processing of workpieces. However, during high-speed and high-precision processing, a large amount of heat will be generated in various components of the machine tool, especially key parts such as the main shaft and cutting tool. If this heat cannot be dissipated in time, it will cause the temperature of the machine tool to rise, thereby affecting the processing accuracy, reducing the service life of the machine tool, and even causing machine tool failures. Therefore, the cooling device for a numerical control machine tool came into being, and its main purpose is to dissipate the heat generated by the machine tool in a timely and effective manner to ensure that the machine tool operates in a stable temperature environment.

[0003] During the processing of a numerical control machine tool, the cutting operation is one of the core links, and a large amount of cutting chips are often generated during the cutting operation. The cutting chips will move together with the circulating coolant and flow out of the processing area. In order to maintain the cleanliness of the coolant, a filter device is usually set in the cooling system. However, as the cutting operation continues, the cutting chips will gradually accumulate on the filter screen. The traditional treatment method often requires staff to manually clean the cutting chips on the filter screen. This cleaning method not only increases the labor intensity of the staff, but also affects the processing efficiency and continuity of the numerical control machine tool. Content of the Utility Model

Detailed implementation manners

[0020] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The following will describe the present application in detail with reference to the drawings and in combination with the embodiments.

[0021] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0022] As Figures 1-4 shown, the present application provides a cooling device for a numerically controlled machine tool, including a coolant pool 1; a mounting plate 2 fixedly installed on the coolant pool 1; a purging mechanism 7 installed on the mounting plate 2 for purging the cutting chips cut off; the purging mechanism 7 includes a fixed rod 701 installed on the mounting plate 2, an installation bracket 702 fixedly installed on the fixed rod 701, a fixing member 711 installed on the installation bracket 702, and a purging port 712 installed on the fixing member 711; a transmission mechanism 4 installed on the mounting plate 2 for driving the purging mechanism to move; the transmission mechanism 4 includes a second rack 405 installed on the mounting plate 2.

[0023] In this embodiment: Since the mounting plate 2 is installed on the coolant pool 1, and the transmission mechanism 4 is installed on the mounting plate 2, the staff can drive the collection box 407 and the purging mechanism 7 to move towards each other by controlling the transmission mechanism 4, so as to fully collect the cutting chips on the filter screen 3. By controlling the purging mechanism 7, the cutting chips can be fully purged, avoiding the clogging of the filter holes on the filter screen 3 and affecting the subsequent filtering operation.

[0024] Specifically, as Figure 2 shown, the filter screen 3 is fixedly installed on the coolant pool 1, the connecting pipe 5 is fixedly installed on the mounting plate 2, and the liquid spraying port 6 is fixedly connected to the connecting pipe 5.

[0025] In this embodiment: Since the connecting pipe 5 is installed on the mounting plate 2, and the liquid spraying port 6 is installed on the connecting pipe 5, the filtered coolant inside the coolant pool 1 can be reused through the liquid spraying port 6, avoiding the waste of resources.

[0026] Specifically, as Figure 4 shown, the purging mechanism 7 includes a second motor 703 installed on the mounting frame 702. The output end of the second motor 703 is provided with a rotating disc 704. A sliding sleeve 705 is rotatably connected to the rotating disc 704. A connecting piece 707 is slidably connected to the sliding sleeve 705. A connecting rod 708 is fixedly connected to the connecting piece 707. The connecting rod 708 is rotatably connected to the fixing piece 711. A rotating cylinder 710 is rotatably connected to the mounting frame 702. The rotating cylinder 710 is rotatably connected to the fixing piece 711; A sliding rod 706 is fixedly connected to the connecting piece 707. The sliding rod 706 is slidably connected to the sliding sleeve 705. The sliding sleeve 705 and the connecting piece 707 are slidably connected through the sliding rod 706; A hanging ear 709 is fixedly connected to the connecting rod 708. The hanging ear 709 is rotatably connected to the fixing piece 711. The fixing piece 711 and the connecting rod 708 are rotatably connected through the hanging ear 709.

[0027] In this embodiment: Since the fixing rod 701 is fixedly installed on the second rack 405, the fixing rod 701 is fixedly connected to the mounting frame 702. The second motor 703 is installed on the mounting frame 702. The output end of the second motor 703 is provided with a rotating disc 704. The sliding sleeve 705 is fixedly installed on the rotating disc 704. The sliding sleeve 705 and the connecting piece 707 are slidably connected through the sliding rod 706. The staff can drive the rotation of the rotating disc 704 by controlling the rotation of the mounting frame 702, thereby driving the rotation of the connecting rod 708, driving the rotation of the fixing piece 711, and the fixing piece 711 is fixedly connected to the purging port 712, so that the purging port 712 fully purges the cutting chips on the filter screen 3, thus avoiding the clogging of the filter holes on the filter screen 3.

[0028] Specifically, as Figure 3As shown in the figure, the transmission mechanism 4 includes a first motor 406 installed on the mounting plate 2. A gear 404 is provided at the output end of the first motor 406. The gear 404 is meshed with a first rack 403 and is also meshed with a second rack 405. The second rack 405 is slidably connected to the mounting plate 2. A collection box 407 is fixedly connected to the first rack 403. A waste slot 401 is slidably connected to the collection box 407.

[0029] In this embodiment: Since the transmission mechanism 4 includes the first motor 406 fixedly installed on the mounting plate 2, a gear 404 is provided at the output end of the first motor 406. The gear 404 is meshed with the first rack 403 and the second rack 405. The gears 404 and 495 are slidably connected to the mounting plate 2 through the chute 402. The staff controls the rotation of the first motor 406, thereby driving the first rack 403 and the second rack 405 to move towards each other. The fixed positions of the second rack 405 and the fixed rod 701 are different from the fixed positions of the first rack 403 and the collection box 407. When the purging mechanism 7 purges the cutting chips to one end of the filter screen 3, the cutting chips are just purged into the collection box 407, so that the cutting chips can be collected well.

[0030] The specific solution is as follows: When cutting a workpiece, the cutting chips accumulate on the filter screen 3. The staff controls the transmission mechanism 4, thereby driving the collection box 407 and the purging mechanism 7 to move towards each other, so that the purging mechanism 7 can purge the cutting chips accumulated on the filter screen 3 into the collection box 407, which can effectively reduce the working intensity of the staff. By controlling the purging mechanism 7, the cutting chips on the filter screen 3 can be purged evenly, effectively avoiding the blockage of the filter screen 3 and maintaining the cleanliness of the coolant. The coolant can be reused through the liquid spraying port 6.
