[0002] CNC machine tools are a widely used type of processing equipment. During the processing, there is no separation between the tool head and the machine tool body, which makes it easy for processing debris to fall into the tool head. This causes aluminum shavings to adhere to the tool holder, which in turn causes vibration during the next tool's processing. To address this, existing technologies can install a water curtain structure on CNC machine tools.

[0003] A water curtain is a continuous curtain of water formed around the cutting tool of a CNC machine tool. Firstly, it can cool the cutting tool; secondly, it can block splashing metal debris. For example, there is a water curtain device for CNC machine tools in the prior art with the publication number CN214722766U.

[0004] Existing water curtains are generally composed of multiple dense water columns, but there will inevitably be gaps between two adjacent water columns. Therefore, the blocking effect of existing water curtains needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a cooling water curtain. By swinging the water curtain nozzles left and right, each water column that makes up the water curtain swings left and right, thus increasing the coverage area of ​​the water column.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-7 The cooling water curtain shown includes a main pipe 1 installed on the rear side of the CNC machine tool cutter head, a sliding component 2 provided at the outer end of the main pipe 1, and a driving component 6 for driving the sliding component 2 to slide left and right on the rear side of the main pipe 1.

[0029] The sliding component 2 includes a sleeve 201 sleeved on the outer end of the main pipe 1. The outer end of the main pipe 1 has a plurality of through holes 8 located inside the sleeve 201. A plurality of water curtain spray pipes 3 are fixed on the front side of the sleeve 201. A spring 203 is fixed on one end of the sleeve 201.

[0030] The sleeve 201 is provided with a first end plate 204 and a second end plate 205 fixed to the outer end of the main pipe 1 on both sides. The first end plate 204 and the second end plate 205 limit the sliding range of the sleeve 201. One end of the spring 203 is fixedly connected to the first end plate 204.

[0031] A bellows 202 is provided between the sleeve 201 and the first end plate 204. The spring 203 is located outside the main pipe 1, and the bellows 202 is located outside the spring 203. Both ends of the sleeve 201 are inlaid with sealing rings, and the inner side of the sealing ring is in contact with the outer end of the main pipe 1.

[0032] The cooling water curtain is installed at the cutter head of the CNC machine tool. During use, cooling water is injected into the main pipe 1. The cooling water entering the main pipe 1 flows into the sleeve 201 through the through hole 8 and is sprayed out through the water curtain nozzle 3 to form multiple water columns. The water curtain is located between the cutter head and the machine tool, which can isolate the debris splashed during the machining process and prevent the debris from falling into the cutter head and causing aluminum chip residue to adhere to the tool holder, thereby preventing vibration during the next tool machining.

[0033] While forming the water curtain, the sleeve 201 is driven by the drive component 6 to slide left and right at the outer end of the main pipe 1. During the sliding process, the spring 203 is repeatedly stretched and compressed as the sleeve 201 moves. The movement of the sleeve 201 causes the water curtain nozzle 3 to swing left and right. In this way, each water column that makes up the water curtain swings left and right, thus increasing the coverage area of ​​the water column. The gaps between the water columns change position continuously with the swing, reducing the probability of debris passing through the gaps. As a result, the overall blocking effect of the water curtain is improved.

[0034] In order to drive the sleeve 201 to move quickly left and right, such as Figure 1 , 4 As shown in Figure 5, a bracket 9 is fixedly provided at the top of the sleeve 201. One end of the bracket 9 is bent horizontally backward and fixedly provided with an iron sheet 10, with the iron sheet 10 facing downward.

[0035] The drive assembly 6 includes a mounting plate 601. A rotating wheel 602 is provided on the front side of the mounting plate 601 via a rotating shaft. A magnet 603 is fixedly provided on the outer end of the rotating wheel 602. A motor 604 for driving the rotating wheel 602 to rotate is fixedly provided on the rear side of the mounting plate 601. The rotating wheel 602 is located at the bottom of the iron sheet 10.

[0036] Both ends of the main pipe 1 are fixed with fixing plates. The water curtain is installed on the machine tool through the fixing plates. The mounting plate 601 is located on the rear side of the main pipe 1 and fixed on one of the fixing plates. The top end of the main pipe 1 is fixed with a water injection pipe. Water is introduced into the main pipe 1 through the water injection pipe.

[0037] During the processing, the motor 604 is turned on, which drives the rotating wheel 602 to rotate at high speed. The magnet 603 at the outer end of the rotating wheel 602 rotates with it. When the magnet 603 rotates close to the iron piece 10, the magnet 603 and the iron piece 10 will attract each other with magnetic force. When the magnet 603 rotates further, the magnetic force will drive the iron piece 10 and the bracket 9, and then drive the sleeve 201 to move laterally. The spring 203 is thus stretched. As the rotating wheel 602 rotates further, the distance between the magnet 603 and the iron piece 10 increases, the magnetic force between them weakens, and the elastic force of the spring 203 will pull the sleeve 201 to move back. Therefore, the rotation of the rotating wheel 602 drives the sleeve 201 to move back and forth.

[0038] In addition to blocking debris, water cooling is also necessary, such as... Figure 1 , 6 As shown in Figures 7 and 8, a lower branch pipe 4 is provided at the bottom of the main pipe 1. Both ends of the lower branch pipe 4 are fixedly connected to the main pipe 1. Multiple cooling spray pipes 5 are connected to the front side of the lower branch pipe 4 through a movable connector 7.

[0039] The movable connector 7 includes a spherical shell 701. A pipe connected to the lower branch pipe 4 is fixedly provided on the rear side of the spherical shell 701. An adjusting ball 702 is fixedly provided at one end of the cooling spray pipe 5 facing the lower branch pipe 4. The adjusting ball 702 is located inside the spherical shell 701 and its outer end is in contact with the inner wall of the spherical shell 701. A fastening bolt is provided on the outer end of the spherical shell 701 through a thread. After the fastening bolt is tightened, the adjusting ball 702 can no longer rotate.

[0040] The cooling water entering the main pipe 1 also enters the lower branch pipe 4 and flows into the cooling spray pipe 5 through the movable connector 7. The cooling water sprayed from the cooling spray pipe 5 is directed at the contact area between the tool and the workpiece to cool the tool and the workpiece. The cooling spray pipe 5 and the lower branch pipe 4 are connected by the movable connector 7. The adjusting ball 702 can rotate inside the ball shell 701 to adjust the direction of the cooling spray pipe 5, so that the cooling spray pipe 5 is more accurately pointed at the contact area between the tool and the workpiece. After the adjustment is completed, tighten the fastening bolt to fix the adjusting ball 702 and the cooling spray pipe 5.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
