Description

Technical Field

[0002] A CNC lathe is an automated lathe with digital program control as its core. It is mainly used to process rotating parts such as shafts and discs.

For thin-walled parts, excessive clamping force can directly cause workpiece deformation and damage its original dimensional accuracy. For soft materials such as aluminum and copper, it may leave obvious indentations or damage at the clamping point, affecting the workpiece's surface quality and even its performance.

[0034] 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.

[0035] like Figure 1-6 As shown, this utility model provides a technical solution: a centrifugal chuck adaptive CNC lathe, comprising:

[0036] Machine tool body 1;

[0037] Centrifugal clamping assembly 2 includes a motor 21 and a base frame 22 installed inside the machine tool body 1. A series rod 24 is slidably connected to the base frame 22. A lever 25 is slidably connected to the series rod 24. A centrifugal block 27 is connected to the lever 25. A sliding block 23 and an outer slider 26 are slidably connected to the centrifugal block 27. An outer top frame 210 is slidably connected to the sliding block 23. A lever 211 is rotatably connected to the machine tool body 1. A square block 214 is connected to the lever 211 via a stop rod 213. A clamping plate 217 is fixedly connected to the square block 214 via an outer lever 216.

[0038] Firstly, this utility model eliminates the reliance on hydraulic or pneumatic systems. It generates centrifugal force by driving the series rod 24 to rotate through the motor 21. This centrifugal force is transmitted through mechanical structures such as the paddle 25 and centrifugal block 27 to achieve clamping. This eliminates the need for pump stations, pipelines, and rotary joints required by traditional chucks, thereby eliminating the uncertainty of clamping force caused by pipeline pressure loss from the root and avoiding uncontrolled clamping force caused by pressure fluctuations.

[0039] The clamping force can be adjusted by the speed of motor 21. The magnitude of centrifugal force changes regularly with the speed, and the clamping force can be flexibly adjusted according to the material and structural characteristics of the workpiece. When clamping thin-walled or soft materials, the centrifugal force can be controlled by reducing the speed. The clamping force is limited by the volume of the outer slider 26, which avoids excessive clamping force causing workpiece deformation, surface indentation and other damage, and effectively protects the dimensional accuracy and surface quality of the workpiece.

[0040] Furthermore, the simplified structure improves clamping stability and reliability. The sliding block 23 and the outer slider 26 are linked through the series frame 5 to ensure that multiple levers 25 move synchronously. Together with the square block 214 and the outer lever 216 connected by the universal joint 215, the clamping plate 217 is subjected to uniform force, reducing the risk of local overload. At the same time, it avoids the interference of hydraulic system oil leakage and pneumatic system pressure loss on the clamping effect.

[0041] In addition, the overall system complexity is reduced, maintenance points and troubleshooting difficulty are reduced, and the energy transmission efficiency of the 21-motor drive is higher and the response speed is faster, which can quickly adapt to the clamping requirements of different workpieces and improve the machining adaptability and safety of CNC lathes.

[0042] Furthermore, such as Figures 1 to 6 As shown, a series frame 5 is fixedly connected to the sliding block 23, and an opening is provided on the bottom frame 22. The sliding block 23 is slidably connected in the opening on the bottom frame 22. In use, by setting the series frame 5 fixedly connected to the sliding block 23, it is convenient to connect multiple paddles 25 in series.

[0043] like Figure 4 As shown, the bottom of the connecting rod 24 is fixedly connected to the output end of the motor 21. A vertical groove is provided on the connecting rod 24. A vertical shaft 29 is fixedly connected to the lever 25. The vertical shaft 29 is slidably connected in the vertical groove on the connecting rod 24. A first rotating shaft 28 is rotatably connected to the lever 25. The first rotating shaft 28 is rotatably connected to the centrifugal block 27. In use, by setting the bottom of the connecting rod 24 to be fixedly connected to the output end of the motor 21, it is convenient to control the displacement of the connecting rod 24 through the motor 21.

[0044] The machine tool body 1 has an opening. The lever 211 is rotatably connected to the opening on the machine tool body 1 through the third rotating shaft 3. The outer top frame 210 is slidably connected to the lever 211. When in use, the opening on the machine tool body 1 facilitates the installation of the third rotating shaft 3. The third rotating shaft 3 rotates in the opening and is fixedly connected to the lever 211.

[0045] A fixed plate 4 is fixedly connected to the machine tool body 1. A vertical hole is opened on the fixed plate 4. The outer lever 216 is slidably connected in the vertical hole on the fixed plate 4. When in use, the fixed plate 4 is fixedly connected to the machine tool body 1, and the fixed plate 4 serves as a support.

[0046] like Figures 1 to 2 As shown, a stop bar 213 is rotatably connected to the lever 211 via a second rotating shaft 212. A universal joint 215 is fixedly connected to the stop bar 213. The side of the universal joint 215 on the stop bar 213 away from the stop bar 213 is fixedly connected to the square block 214. In use, the universal joint 215 makes the connection between the stop bar 213 and the directional block more flexible.

[0047] Sliding block 23 and outer slider 26 are both fixedly connected by series frame 5. In use, by setting sliding block 23 and outer slider 26 to be fixedly connected by series frame 5, when one of sliding block 23 or outer slider 26 is moved, it will drive the other sliding block 23 and outer slider 26 to move synchronously.

[0048] Working principle:

[0049] like Figure 1-6 As shown, during use, starting the motor 21 causes the connecting rod 24 to rotate within the bottom frame 22, which in turn causes the paddle 25 to rotate, swinging the centrifugal block 27. This causes the centrifugal block 27 to gradually press against the sliding block 23, causing the sliding block 23 or the outer slider 26 to extend out and press against the outer top frame 210. This causes the outer top frame 210 to drive the paddle 211 to rotate, which in turn causes the paddle 211 to drive the second rotating shaft 212 to slide down. This causes the paddle 211 to drive the abutment 213 to slide down, which in turn causes the abutment 213 to drive the square block 214 to press inward through the universal joint 215. This causes the outer paddle 216 and the clamping plate 217 to clamp inward, tightly clamping the material placed on the machine tool body 1 and completing the material clamping process.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
