Description

Technical Field

[0001] This utility model relates to the field of lathe technology, and in particular to a flat-bed CNC lathe. Background Technology

[0002] Turning is a common machining method in the field of machining. Its most prominent feature is that the workpiece and the cutting tool have relative rotational motion. The most common method is to keep the cutting tool in a straight feed while the workpiece rotates with the spindle. Due to the relative rotation, the chips produced by turning often become entangled and form clumps. This phenomenon is particularly obvious when machining materials with good toughness, such as ordinary carbon steel and non-metallic materials.

[0003] The inventors of this application have discovered the following problems during practical use:

[0004] During the current machine tool cutting process, the chips cut off often curl up and may get tangled on the workpiece surface or the cutting tool, scratching the machined surface. Therefore, machine tools can modify the tool holder of the cutting tool to add a separate high-pressure nozzle, so that high-pressure liquid can be sprayed out during cutting to break the chips. However, this modification requires the use of a special tool holder, which is expensive and has a short service life.

[0005] Therefore, it is necessary to provide a flatbed CNC lathe to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the modification requires the use of special tool holders, which are expensive and have a short service life. In view of the above-mentioned defects of the prior art, a flat bed CNC lathe is provided.

[0007] To achieve the above objectives, the technical solution of this utility model is: a flat-bed CNC lathe, including a lathe, a fixing mechanism is provided on the slide of the lathe, the fixing mechanism includes a U-shaped frame, a through hole is opened on one side of the U-shaped frame, a vertical rod is provided inside the through hole, a support plate is fixedly connected to one end of the vertical rod, a crossbar is fixedly connected to one side of the support plate, and a first clamp is rotatably connected to one end of the crossbar through a damping shaft, and a high-pressure nozzle is fixedly connected inside the first clamp.

[0008] By adopting the above technical solution, and by setting a fixing mechanism on the lathe slide, and specifically designing a structure including a U-shaped frame, upright, support plate, crossbar, damping shaft, first clamp and high-pressure nozzle, the high-pressure nozzle can be flexibly installed and its angle adjusted on the lathe.

[0009] Furthermore, a first magnet is fixedly connected to the bottom of the support plate, and a ball groove is formed on the inner wall of the support plate, with a ball bearing disposed inside the ball groove.

[0010] By adopting the above technical solution, a first magnet is fixedly connected to the bottom of the support plate, and a ball groove is opened to house the ball bearings. The first magnet can enhance the attraction between the support plate and the tool holder, so that the support plate remains stable when the tool holder rotates.

[0011] Furthermore, multiple ball grooves and balls are provided, and the multiple ball grooves and balls are arranged in a ring evenly.

[0012] By adopting the above technical solution, multiple ball grooves and balls are set and arranged in a uniform ring, which further enhances the stability and flexibility between the support plate and the tool holder.

[0013] Furthermore, the bottom end of the upright is threaded, and a first nut and a second nut are threaded onto the thread. The first nut, the U-shaped bracket, and the second nut are arranged sequentially from top to bottom.

[0014] By adopting the above technical solution, the bottom end of the pole is threaded, and a threaded connection is achieved through the first nut and the second nut.

[0015] Further, the two sides of the U-shaped frame are respectively threaded with a first bolt and a second bolt, and one end of the U-shaped frame is rotatably connected with a baffle.

[0016] By adopting the above technical solution, the first bolt and the second bolt are threaded to both sides of the U-shaped frame, and a baffle is rotatably connected to one end of the U-shaped frame, so that the U-shaped frame can be firmly fixed on the lathe slide.

[0017] Furthermore, a base is fixedly connected to the other end of the U-shaped frame, and a second magnet is fixedly connected to the bottom of one end of the baffle.

[0018] By adopting the above technical solution, the other end of the U-shaped frame is fixedly connected to the base, and a second magnet is fixedly connected to the bottom of one end of the baffle. The base provides an additional support point for the U-shaped frame, enhancing its stability.

[0019] Furthermore, a water pipe is fixedly connected to the other side of the high-pressure nozzle, and the water pipe is connected to an external water pump.

[0020] By adopting the above technical solution, a water pipe is fixedly connected to the other side of the high-pressure nozzle, and the water pipe is connected to an external water pump, so that the high-pressure nozzle can continuously and stably obtain a high-pressure liquid supply, ensuring that it can continuously and effectively break the chips during the cutting process.

[0021] As a further feature, a second clip is fixedly connected to each of the adjacent sides of the top of the support plate, and the second clip is used to fix the water pipe.

[0022] By adopting the above technical solution, second clips are fixedly connected to the top adjacent sides of the support plate to fix the water pipe, so that the water pipe can be firmly fixed on the support plate and avoid affecting the spraying effect of the high-pressure nozzle due to shaking or falling off during the cutting process.

[0023] Compared with related technologies, the flat-bed CNC lathe provided by this utility model has the following beneficial effects:

[0024] This utility model provides a flat-bed CNC lathe. By setting a fixing mechanism, a high-pressure nozzle can be firmly installed on the lathe's slide plate, ensuring that the high-pressure nozzle will not shake or fall off during the cutting process, thereby improving the cutting accuracy and stability. The fixing mechanism also has a cutting area to effectively break up the chips and prevent them from getting tangled on the workpiece or tool, further improving the processing quality and efficiency.

[0032] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings show typical embodiments of this utility model. Example

[0033] like Figure 1 As shown, this utility model discloses a flat-bed CNC lathe, including a lathe 1. A fixing mechanism 3 is provided on the slide plate 2 of the lathe 1. The fixing mechanism 3 includes a U-shaped frame 301. A through hole 302 is opened on one side of the U-shaped frame 301. A vertical rod 303 is provided inside the through hole 302. A support plate 304 is fixedly connected to one end of the vertical rod 303. A crossbar 305 is fixedly connected to one side of the support plate 304. A first clamp 307 is rotatably connected to one end of the crossbar 305 through a damping shaft 306. A high-pressure nozzle 308 is fixedly connected inside the first clamp 307. The high-pressure nozzle 308 can accurately spray high-pressure liquid onto the cutting area, effectively breaking up the chips and preventing the chips from getting tangled on the workpiece or tool, thus improving the processing quality and efficiency.

[0034] like Figure 2 As shown, a first magnet 319 is fixedly connected to the bottom of the support plate 304. A ball groove 309 is provided on the inner wall of the support plate 304. A ball ball 310 is provided inside the ball groove 309. The ball groove 309 and the ball ball 310 reduce the friction between the support plate and the tool holder, so that the support plate 304 can move more smoothly with the tool holder, thereby improving the flexibility and stability of the entire fixing mechanism.

[0035] like Figure 2 As shown, multiple ball grooves 309 and balls 310 are provided. The multiple ball grooves 309 and balls 310 are arranged in a ring and uniformly. No matter how the tool holder rotates or moves, the support plate 304 can maintain balance and stability through the uniform distribution of multiple balls 310, thereby ensuring the spray direction and stability of the high-pressure nozzle 308.

[0036] like Figure 2 As shown, the bottom end of the upright 303 is provided with a thread 311, and a first nut 312 and a second nut 313 are threaded onto the thread 311. The first nut 312, the U-shaped frame 301 and the second nut 313 are arranged sequentially from top to bottom. The overall structure allows the height and position of the upright 303 to be easily adjusted, thereby adjusting the position of the high-pressure nozzle 308 and adapting to different lathes. Through the cooperation of the two nuts, the position of the upright 303 can be firmly locked to ensure the stability of the high-pressure nozzle 308 during the cutting process.

[0037] like Figure 4As shown, the U-shaped frame 301 is threaded with a first bolt 314 and a second bolt 315 on both sides, and a baffle 316 is rotatably connected to one end of the U-shaped frame 301. The presence of the baffle 316 can further enhance the stability of the entire fixing mechanism. The rotatable connection of the baffle 316 also facilitates installation to adapt to different installation environments.

[0038] like Figure 3 As shown, the other end of the U-shaped frame 301 is fixedly connected to the base 317, and the bottom of one end of the baffle 316 is fixedly connected to the second magnet 318. The second magnet 318 can magnetically attract the base 317 to further fix the position of the baffle 316 and prevent it from shaking or falling off during the cutting process.

[0039] like Figure 4 As shown, a water pipe 4 is fixedly connected to the other side of the high-pressure nozzle 308. The water pipe 4 is connected to an external water pump. The connection of the water pipe 4 also facilitates quick replacement in case of damage, improving the maintenance efficiency of the equipment and reducing installation time.

[0040] In practice, the frame consisting of U-shaped frame 301 and baffle 316 is fitted onto the root of the tool post. The U-shaped frame 301 is fastened to the root of the tool post of the lathe 1 by the first bolt 314 and the second bolt 315 to ensure that the frame is stable and does not move. The base 317 and the second magnet 318 attract each other to fix the baffle 316, making the frame more robust.

[0041] Next, the support plate 304 is placed on top of the tool holder and connected to the U-shaped frame 301 through the through hole 302 via the upright 303. The bottom end of the upright 303 is locked by engaging the first nut 312 and the second nut 313 with the thread 311.

[0042] When installing the high-pressure nozzle 308, loosen the first nut 312 and the second nut 313, and adjust the position of the support plate 304 and the high-pressure nozzle 308 by rotating or moving the upright 303 up and down, so that the inner wall of the support plate 304 can touch the top of the knife holder. After the adjustment is completed, tighten the first nut 312 and the second nut 313 again to fix the upright 303 in the U-shaped frame 301.

[0043] Then, the high-pressure nozzle 308 is fixed to one end of the crossbar 305 by the first clamp 307 and the damping shaft 306. The high-pressure nozzle 308 can rotate around the damping shaft 306 at a certain angle so as to adjust the spray direction of the nozzle according to the cutting requirements.

[0044] During the cutting process, an external water pump delivers high-pressure liquid to the high-pressure nozzle 308 through water pipe 4. The high-pressure liquid is sprayed out from the nozzle, forming a powerful water flow that directly impacts the cutting area, breaking and carrying away the chips, thus preventing the chips from entangled on the workpiece surface or the tool. After breaking, the spray can be manually stopped to avoid wasting water flow, and it also reduces the stress on the U-shaped frame 301 and the baffle 316.

[0045] In addition, a first magnet 319 is provided at the bottom of the support plate 304, which can be attracted to the tool holder, so that the high-pressure nozzle can remain stable when the tool holder rotates to change tools, further enhancing the stability of the support plate. Example

[0046] like Figure 5 As shown, based on Embodiment 1, this utility model provides a technical solution: a second clip 5 is fixedly connected to the top adjacent sides of the support plate 304. The second clip 5 is used to fix the water pipe 4. The second clip 5 also facilitates the quick installation and disassembly of the water pipe, improving the convenience and maintainability of the entire device.

[0047] The implementation principle of this utility model is as follows: First, the water pipe 4 can be fixed to the top adjacent side of the support plate 304 by the second clamp 5 to ensure that the water pipe 4 will not shake or fall off during the cutting process.

[0048] The advantages of this technical solution in practical applications include, but are not limited to, the following:

[0049] 1. By setting a fixing mechanism, the high-pressure nozzle can be firmly installed on the lathe's slide plate. The structure is compact, the installation speed is fast, and the modification cost is low.

[0050] 2. The second clamp provides a stable fixing point for the water pipe, ensuring that the water pipe will not shake or fall off due to the impact of the sudden start of water flow during the cutting process.

[0051] 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.
