Abstract
Description
Technical Field
[0001] This utility model relates to the field of countersunk hole machining technology, and in particular to a cooling device for countersunk hole machining. Background Technology
[0002] Countersinking is a key process in the processing of NdFeB permanent magnets. NdFeB, due to its excellent magnetic properties, is widely used in many fields, and countersinking aims to better meet practical installation and usage requirements. During processing, the high hardness and brittleness of NdFeB present significant challenges. On the one hand, cutting tools wear easily, so suitable carbide tools must be selected to ensure cutting efficiency. On the other hand, due to its brittleness, improper parameter control during processing can easily lead to cracks and chipping at the hole edge. Therefore, precise adjustment of cutting speed, feed rate, and other parameters is necessary, along with the use of appropriate cutting fluid to cool and reduce cutting forces. From a functional perspective, countersinking makes the installation of NdFeB permanent magnets more convenient. For example, in the installation of motor rotors or stators, countersinking allows the head of the fixing component to be concealed, resulting in a flat mounting surface. It also allows for precise control of the installation position and orientation, improving assembly accuracy. This is crucial for applications requiring high magnetic field precision, such as precision instruments and medical devices. In summary, although countersinking neodymium iron boron magnets is challenging, it plays an indispensable role in maximizing their magnetic properties and ensuring high-quality product installation.
[0003] Existing countersinking equipment often generates a large amount of heat during operation. This is because the continuous cutting friction between the tool and the workpiece during countersinking converts a significant amount of mechanical energy into heat. This friction is particularly intense when machining high-hardness materials, such as neodymium iron boron, leading to faster heat accumulation. Excessive heat not only easily causes excessive wear on the tool, shortening its service life, but may also affect the machining accuracy and surface quality of the workpiece. To address this technical problem, this application proposes a cooling device for countersinking. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cooling device for countersinking. The device sprays coolant from the water tank onto the drill bit of the countersinking machine by activating the nozzle, thereby reducing the temperature of the drill bit. When the device is used for a long time, the second motor is activated to drive the connecting rod to rotate the scraper and scrape off the scale on the inner wall of the water tank.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A cooling device for countersinking includes a processing box. A support rod is fixedly connected to the top of the processing box. A threaded rod is rotatably connected to the inner wall of the support rod. A connecting block is threadedly connected to the outer wall of the threaded rod.

The inner walls of the two limiting sliders are connected through a limiting assembly to control the distance between the two limiting sliders. The adjacent sides of the two limiting sliders are inserted into the left and right sides of the filter screen.
[0007] Furthermore, the rotating assembly includes a gear fixedly connected to the top of the scraper, and a toothed ring fixedly connected to the top side of the inner wall of the nozzle, with the outer wall of the gear meshing with the inner wall of the toothed ring.
[0008] Furthermore, a second motor is fixedly connected to the top of the water tank, and the top end of the connecting rod is fixedly connected to the drive end of the second motor.

[0015] In this invention, during operation, the coolant carries debris into the processing chamber, and after being filtered by the filter screen, it is discharged. The filter screen adsorbs and filters the iron filings. Rotating the adjustment knob releases the limit slider that limits the filter screen, allowing the filter screen to be removed for cleaning.

A gear 15 is fixedly connected, and a toothed ring 16 is fixedly connected to the top side of the inner wall of the nozzle 14. The outer wall of the gear 15 meshes with the inner wall of the toothed ring 16. During rotation, the gear 15 meshes with the toothed ring 16, causing the gear 15 to rotate. The gear 15 drives the scraper 13 to rotate and scrape the scale on the inner wall of the water tank 4. A second motor 8 is fixedly connected to the top of the water tank 4. The top of the connecting rod 12 is fixedly connected to the driving end of the second motor 8. The second motor 8 drives the connecting rod 12 to rotate. A first motor 7 is fixedly connected to the top of the support rod 2. The top of the threaded rod 6 is fixedly connected to the driving end of the first motor 7, driving the threaded rod 6 to rotate. Two limiting rods 11 are fixedly connected to the top of the processing box 1. The outer wall of the limiting rod 11 is slidably connected to the right side of the connecting block 3, making the connecting block 3 slide stably.
[0025] Reference Figure 1 , Figure 4 and Figure 5 The bottom side of the inner wall of the processing box 1 is equipped with a mechanical claw 9, which is a mechanical device widely used in many fields. It typically consists of multiple movable joints and grippers, and can be opened and closed by power to precisely grasp objects of different shapes and sizes. The processing box 1 has a sliding groove, and a filter screen 17 is inserted into the inner wall of the groove to adsorb and filter iron filings in the coolant. Two limit sliders 18 are slidably connected to the bottom of the inner wall of the sliding groove. The inner walls of the two limit sliders 18 are threaded with a bidirectional screw 19. The rotation of the bidirectional screw 19 drives the limit sliders 18 to slide. A worm wheel 20 is fixedly connected to the left side of the outer wall of the bidirectional screw 19. The rotation of the worm wheel 20 drives the bidirectional screw 19 to rotate. The side of the two limit sliders 18 that is close to each other is inserted into the left and right sides of the filter screen 17 to limit the filter screen 17. A worm 21 is rotatably connected to the front of the processing box 1. The outer wall of the worm 21 meshes with the outer wall of the worm wheel 20. An adjustment knob 10 is fixedly connected to the front end of the worm 21. Rotating the adjustment knob 10 causes the worm 21 to rotate, and the rotation of the worm 21 meshes with the worm wheel 20 to rotate.
[0026] Working principle: When starting work, the mechanical claw 9 clamps the material to be countersinked. The first motor 7 is started to drive the threaded rod 6 to rotate, so that the connecting block 3 drives the countersinking machine 5 to slide and countersink the material. During the operation, the nozzle 14 is started to spray the coolant in the water tank 4 onto the drill bit of the countersinking machine 5 to reduce the temperature of the drill bit. When the device is used for a long time, the second motor 8 is started to drive the connecting rod 12 to rotate. The connecting rod 12 drives the scraper 13 to rotate. During the rotation, the gear 15 meshes with the gear ring 16 to rotate the gear 15. The gear 15 drives the scraper 13 to rotate and scrape the scale on the inner wall of the water tank 4.
[0027] During operation, the coolant carries debris into the processing chamber 1, and is discharged after being filtered by the filter screen 17. The filter screen 17 adsorbs and filters the iron filings. When the filter screen 17 needs to be removed for cleaning after a long period of use, turn the adjustment knob 10 to rotate the worm 21. The rotation of the worm 21 engages with the worm wheel 20, causing the worm wheel 20 to drive the double-acting screw 19 to rotate. The rotation of the double-acting screw 19 causes the limit slider 18 to slide, releasing the limit slider 18 from the filter screen 17, allowing the filter screen 17 to be removed for cleaning.
