Description

Technical Field

[0001] This utility model relates to the field of CNC lathe machining technology, specifically a water supply device for CNC lathe machining. Background Technology

[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting and machining the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other machining operations.

[0003] Chinese Utility Model Publication No. CN212917645U discloses a water supply device for CNC lathe machining, including a CNC lathe and a lathe rotating device for driving the material to rotate. The lathe rotating device extends into the CNC lathe. A water storage box is fixedly connected to the top of the CNC lathe. A cooling nozzle extending into the CNC lathe is fixedly connected to the bottom of the water storage box. A lifting plate is fixedly connected to the top of the spring. A water inlet valve extending into the water storage box and located below the piston pressure plate is fixedly connected to the side wall of the water storage box.

[0004] This device serves to cool the cutter head by spraying water in case of emergencies. However, the piston plate, spring, and water tank are mostly fixed together. When the piston plate and spring are worn out after a period of use or under external force, they are difficult to disassemble and take a long time to repair or replace, so their practicality is not very good.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2This utility model discloses a water supply device for CNC lathe machining, comprising a CNC lathe 1 and a lathe rotating device 2. A housing 3 is fixedly installed on the upper part of the CNC lathe 1, and a water inlet valve 10 is installed through the side wall of the housing 3. An external water pipe is connected to the water inlet valve 10 to supply water into the housing 3. A cooling nozzle 4 is fixedly connected to the lower part of the housing 3 and extends to a position corresponding to the lathe cutting head inside the CNC lathe 1. The water in the housing 3 enters the cooling nozzle 4 and is sprayed onto the lathe cutting head to cool it down.

[0021] The box body 3 has fixing plates on both sides. The fixing plates have a threaded hole in the middle and a bolt is threadedly connected to it. The upper part of the bolt is fitted with a box cover 5 that covers the upper opening of the box body 3 to prevent water from flowing out of the box body 3. The lower part of the box cover 5 is fitted with a sealing strip. The side wall of the sealing strip abuts against the inner wall of the box body 3 to improve the sealing between the two. The middle part of the box cover 5 is fitted with a through groove 6. A guide block 7 is connected through the through groove 6. A piston pressure plate 8 is fixedly installed at the lower part of the guide block 7. When the guide block 7 moves downward in the through groove 6, it pushes the piston pressure plate 8 downward, presses down the water below, applies sufficient pressure, and then sprays it onto the lathe tool head through the cooling nozzle 4.

[0022] The cover 5 has a set of threaded holes 2, and each of them is threadedly connected to a fixed tube 9. A lifting device is slidably connected inside the fixed tube 9. The piston plate 8 has a threaded hole 3. The lower outer wall of the lifting device has an external thread 3 that matches the threaded hole 3, and is threadedly connected to the threaded hole 3.

[0023] The lower outer wall of the fixed tube 9 is provided with an external thread that matches the threaded hole 2. The operator passes the lifting device through the threaded hole 2 and then presses it on the upper part of the threaded hole 3. Then, the operator presses the fixed tube 9 so that the lower part of the fixed tube 9 is pressed on the upper part of the threaded hole 2. The operator then rotates the fixed tube 9, which drives the lifting device to rotate together, rotating into the threaded hole 2 and the threaded hole 3 respectively, which facilitates disassembly and installation.

[0024] The lifting device includes a lifting rod 11 that slides within a fixed tube 9. A spring 12 is fixedly installed on the upper part of the lifting rod 11. The upper part of the spring 12 is fixedly installed within the fixed tube 9. When the lifting rod 11 moves downward, it stretches the spring 12, and the spring 12 provides an upward pulling force to the lifting rod 11.

[0025] A connecting block 13 is provided at the lower part of the lifting rod 11, and an external thread is provided on the outer wall of the connecting block 13.

[0026] The lifting rod 11 has a rectangular cross-section, which prevents it from rotating inside the fixed tube 9 and ensures that it slides up and down inside the fixed tube 9.

[0027] The upper part of the guide block 7 is provided with a threaded hole four and a bolt two is threadedly connected. The upper part of the bolt two is threadedly connected to a load-bearing box 14. When a weight is added to the load-bearing box 14, it generates downward pressure on the lifting rod 11. The pressure is greater than the tension of the spring 12 and the buoyancy of the water. Then, water is pressed into the cooling nozzle 4.

[0028] In summary, this water supply device for CNC lathe machining is used by the operator by passing the lifting rod 11 of the lifting device through the threaded hole two on the box cover 5, aligning the connecting block 13 with the threaded hole three on the piston pressure plate 8. The lower part of the fixing pipe 9 is pressed against the upper part of the threaded hole two, and rotating the fixing pipe 9 causes the lifting device to rotate together, completing the threaded connection between the fixing pipe 9 and the threaded hole two, and between the connecting block 13 and the threaded hole three, thus achieving a stable installation of the lifting device. Because the lifting rod 11 has a rectangular cross-section, after installation, it can only slide up and down within the fixing pipe 9 and will not rotate. The load-bearing box 14 is fixed to the upper part of the guide block 7 using bolt two. Afterwards, a weight is added to the load-bearing box 14. At this time, the load-bearing box 14 and the weight exert downward pressure on the lifting rod 11. This pressure is greater than the tension of the spring 12 and the buoyancy of the water. The downward movement forces the water into the cooling nozzle 4 and sprays it onto the lathe tool head to cool it down. When the piston pressure plate 8 and other devices need to be repaired or replaced after a period of use, the fixed tube 9 is rotated in the reverse direction, which drives the fixed tube 9 and the lifting rod 11 and other devices to rotate in the reverse direction and remove them from the piston pressure plate 8 and the box 3. Then, the bolt 2 on the load-bearing box 14 is removed, and the guide block 7 can be taken out from the through groove 6 of the box cover 5. Then, the piston pressure plate 8 and other devices can be repaired or replaced.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
