Description

Technical Field

[0001] This utility model relates to the field of industrial design technology, specifically a high-speed dual-spindle machine tool driven by a linear motor. Background Technology

[0002] Twin-spindle machine tools feature a dual-spindle system, allowing for the simultaneous machining of two workpieces or the simultaneous machining of the same workpiece using two different machining methods. The main advantages of this machine tool structure are improved machining efficiency, reduced production costs, and the ability to perform more complex machining tasks.

[0003] Existing machine tools have two processing modes: ordinary processing and high-precision processing. Both modes require water flow to control the heat generated during processing and prevent the drill bit from overheating. However, in high-precision processing, the water flow directly washes over the processing area, which can affect the processing accuracy. In addition, the impact force of ordinary nozzles is relatively large, which can damage the surface of the workpiece, thus having limitations.

[0004] The reason for this problem is that when using ordinary nozzles for rinsing during high-precision machining, the large impact force can damage the surface of the workpiece. When the water flow directly rinsing the machining area, the dynamic pressure and disturbance brought by the direct water flow will affect the tool path and cutting force during the machining process, thus leading to machining errors. Even such small disturbances can have a significant impact on the dimensional and shape accuracy of the final product. Therefore, we propose a high-speed dual-spindle machine tool driven by a linear motor to solve the above problems. Utility Model Content

[0029] Example 1

Figure 1 , 2As shown in Figures 4 and 5, the device includes a body 1. Cutting parts 2 are provided on both sides inside the body 1.

[0031] The nozzle 42 is movably latched inside the base 41. The nozzle 42 is divided into a normal nozzle 421 and a high-precision nozzle 422. The nozzle 42 can be selectively latched to the base 41. The fixing clip 43 is set on one side of the base 41. The fixing clip 43 is used to fix the nozzle 42 when it is slidably set inside the base 41.

[0032] Support cleaning component 3 includes support plate 31, water pipe 32 and cooling pipe 33;

[0033] Support plate 31 is fixedly assembled with body 1; water pipe 32 is arranged on both sides of support plate 31; cooling pipe 33 is arranged at both ends of water pipe 32 and is connected to water pipe 32; base 41 is fixedly installed at the end of cooling pipe 33; fixing clip 43 includes protective shell 431, rotating plate 432 and central shaft 433; protective shell 431 is fixedly assembled on one side of base 41; rotating plate 432 is rotatably connected to the inside of protective shell 431; central shaft 433 is arranged inside rotating plate 432 and rotating plate 432 is rotatably connected to central shaft 433; fixing clip 43 also includes insertion rod 434, push rod 435 and spring 436; insertion rod 434 is fixedly connected to the bottom of one side of rotating plate 432; push rod 435... The top of the rotating plate 432 is fixedly connected to the other side; the spring 436 is wound around one side of the push rod 435, one end of the spring 436 is fixedly connected to the push rod 435, and the other end of the spring 436 is fixedly connected to the protective shell 431. The base 41 has a guide groove 44 inside, and the outer surface of the nozzle 42 is provided with a guide strip 45. The guide strip 45 is slidably connected inside the guide groove 44. The two ends of the guide strip 45 are provided with sealing rings 46. The outer surface of the sealing rings 46 is tightly fitted to the inner wall of the base 41. The outer wall of the nozzle 42 is provided with an insertion hole 47. The insertion rod 434 is movably engaged inside the insertion hole 47. Linear motors 5 are provided on both sides of the cutting part 2. The linear motors 5 are used to drive the cutting part 2 to move laterally.

[0034] In this embodiment, when using the device, the raw material is placed on the support plate 31 and fixed. The linear motor 5 is started, and the linear motor 5 drives the cutting part 2 to move laterally to ensure the cutting effect. The cutting part 2 is internally equipped with a push-pull component and a rotating component. The push-pull component can drive the drill bit to move towards the raw material, facilitating drilling. The rotating component drives the drill bit to rotate, which can complete cutting, drilling and other tasks to meet the user's needs. The linear motor 5 mainly consists of a stator and a mover. The stator is usually fixed on the base, while the mover moves linearly along the axis of the stator. There is a certain gap between the stator and the mover to reduce friction and wear.

Grasp the nozzle 42 and pull it outward to complete the removal of the nozzle 42. Align the guide strips 45 on both sides of the required nozzle 42 with the guide grooves 44 and insert them. Push them to the bottom and release the push rod 435. Under the reaction force of the spring 436, the push rod 435 is pushed back to its original position, and the insertion rod 434 is inserted into the inside of the insertion hole 47 to complete the replacement of the nozzle 42. It should be noted that the function of the sealing ring 46 is to ensure that the fluid does not flow out along the gap between the nozzle 42 and the base 41, thus meeting the user's needs.

[0036] Example 2

[0037] This utility model discloses a high-speed dual-spindle machine tool driven by a linear motor. More specifically, based on Embodiment 1, it is further described according to the appendix... Figure 1 , 3 As shown, it includes a body 1, with cutting parts 2 on both sides inside the body 1, a support cleaning part 3 on one side of the cutting part 2, and a quick replacement unit 4 at the end of the support cleaning part 3. The quick replacement unit 4 includes a base 41, a nozzle 42, and a fixing clip 43.

[0038] The nozzle 42 is movably latched inside the base 41. The nozzle 42 is divided into a normal nozzle 421 and a high-precision nozzle 422. The nozzle 42 can be selectively latched to the base 41. The fixing clip 43 is set on one side of the base 41. The fixing clip 43 is used to fix the nozzle 42 when it is slidably set inside the base 41.

[0039] The high-precision nozzle 422 adopts a gradually expanding tube wall, and a diffusion cavity is opened inside the high-precision nozzle 422, and a perforated plate is provided on the top of the diffusion cavity.

[0040] In this embodiment, when the device is in use, water is injected into the interior of the cooling pipe 33 through the water pipe 32. The cooling pipe 33 is made of flexible material and can freely change direction to adapt to different processing points. The water flows into the interior of the high-precision nozzle 422 through the cooling pipe 33. As the pipe diameter gradually increases, the cross-sectional area of ​​the fluid flow also increases. With the flow rate remaining constant, the flow velocity decreases. Furthermore, the flow velocity decreases further as the fluid enters the diffuser chamber. The fluid is then sprayed out through the perforated plate, changing the original single-point spray to multi-point spray. This reduces the impact on the raw materials while ensuring the cleaning effect, thus meeting the user's needs.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
