[0002] As a precision clamping tool, the development of spring collets can be traced back to the early 20th century in the machining industry. In the early days, they were mainly used in precision fields such as watchmaking. With the popularization of CNC technology, spring collets have been widely used in the tool systems and precision shaft parts clamping of CNC lathes, milling machines and machining centers due to their high concentricity, fast clamping and excellent structural adaptability. They have become a key process equipment for modern manufacturing to achieve efficient and high-precision machining.

Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figures 1-4 This is an embodiment of the present invention, which provides a CNC lathe spring collet clamping device, comprising: The base plate 101, the enclosure 102 fixedly connected to the side wall of the base plate 101, the reserved hole 103 provided on the surface of the enclosure 102, the cylinder 104 adapted to be installed on the side wall of the enclosure 102, the push head 105 fixedly connected to the output end of the cylinder 104, the limiting component 106 movably connected to the inner wall of the reserved hole 103, the adjusting component 107 fixedly connected to the side wall of the base plate 101, and the fixing component 108 fixedly connected to the side wall of the adjusting component 107. The limiting component 106 includes a rod 106a movably connected to the inner wall of the reserved hole 103, a limiting spring 106b sleeved on the surface of the rod 106a, a limiting block 106c fixedly connected to the end of the rod 106a, and a reserved opening 106d opened on the side wall of the limiting block 106c.

[0019] Specifically, the adjustment assembly 107 includes a mounting block 107a fixedly connected to the side wall of the base plate 101, and a guide rod 107b fixedly connected to the inner wall of the mounting block 107a. The adjustment assembly 107 also includes a return spring 107c sleeved on the surface of the guide rod 107b, and a Z-shaped rod 107d fixedly connected to the end of the return spring 107c. The adjustment assembly 107 also includes a pulley 107e connected to the side wall of the Z-shaped rod 107d via a bearing, and a limiting opening 107f opened on the side wall of the Z-shaped rod 107d.

[0020] Furthermore, two Z-shaped rods 107d are provided, symmetrically arranged with the center of the Z-shaped rod 107d as the origin. When the push rod pushes the pulley 107e, the pulley 107e will drive the end of the Z-shaped rod 107d to move to both sides. The guide rod 107b is provided to facilitate the limitation of the movement direction of the Z-shaped rod 107d.

[0021] Preferably, the surface of the pulley 107e is in rolling connection with the surface of the push head 105, the inner wall of the limiting port 107f is in movable connection with the surface of the guide rod 107b, and the fixing assembly 108 includes a fixing pin 108a inserted into the side wall of the Z-shaped rod 107d, and a connecting bearing 108b fixedly sleeved on the side wall of the fixing pin 108a. The fixing assembly 108 also includes a pin 108c fixedly connected to the bottom of the fixing pin 108a, and a clamping block 108d fixedly connected to the side wall of the Z-shaped rod 107d.

[0022] It should be noted that the insertion rod 106a is designed to facilitate insertion into the reserved opening 106d of the limiting block 106c, ensuring the fixation of the fixing pin 108a and the stability of the device during use. The connecting bearing 108b is designed to facilitate the movement of the two Z-shaped rods 107d, and at the same time, facilitates the clamping block 108d to clamp the spring clamp.

[0023] In use, the cylinder 104 is activated, extending and driving the pusher 105 to move towards the clamping block 108d. This pushes the pulleys 107e on both sides, causing the pulleys 107e to move the ends of the two Z-shaped rods 107d away from the pusher 105. The fixing pin 108a is inserted into the center of the two Z-shaped rods 107d, limiting their movement. The other end of the Z-shaped rods 107d moves towards the center, causing the clamping blocks 108d to move closer together. The spring collet is then placed between the two clamping blocks 108d, holding the spring collet in place. The pin 108c works in conjunction with the limit block 106c to ensure the stability of the Z-shaped rod 107d during movement. The insert rod 106a is inserted into the reserved hole 103 and works in conjunction with the limit spring 106b to allow the limit block 106c to move slightly, ensuring that the Z-shaped rod 107d will not be mechanically damaged during use. When the cylinder 104 retracts, the cylinder 104 will drive the push head 105 back to its original position, and the return spring 107c on the surface of the guide rod 107b will push the Z-shaped rod 107d back to its original position, thereby causing the clamping block 108d to return to its original position and releasing the spring clamp.

[0024] In summary, the cylinder 104 drives the pusher 105 to push the pulley 107e, causing the symmetrically arranged Z-shaped rods 107d to move smoothly in both directions with the help of the guide rod 107b and the return spring 107c. This causes the clamping block 108d to move closer or separate, achieving stable clamping and rapid release of the spring collet. The insertion rod 106a and the limiting block 106c work together with the buffering effect of the limiting spring 106b, ensuring both the rigid locking of the fixing pin 108a when it is inserted and the flexible protection for the operation of the Z-shaped rods 107d, effectively avoiding mechanical damage. At the same time, the connecting bearing 108b ensures the synchronous and flexible movement of the two Z-shaped rods 107d, giving the entire clamping device good reliability, adaptability and durability during operation.
