[0039] Example

[0040] See Figures 1-7 As shown, a press-fit collet assembly includes a base plate 1, on which a rotary table 4 driven by a motor 2 is mounted. A vertical channel is centrally located on the rotary table 4, and a support column 8 passing through the vertical channel is mounted on the base plate 1, providing stable support and precise guidance for the entire structure. A sleeve 5 is mounted on the rotary table 4, and a collet assembly 9 is embedded in the upper end of the sleeve 5. The outer frame 91 of the collet assembly 9 is secured to the sleeve 5 by bolts 92, ensuring a secure and reliable connection. A limiting block 93 on the collet assembly 9 is detachably mounted on the support column 8. When the collet assembly 9 needs to be replaced, simply loosening the bolts and limiting block on the outer frame allows for replacement of the entire collet assembly 9, meeting the clamping requirements of different types of rotating shafts.

[0041] In this embodiment, when the outer frame 91 is assembled with the sleeve 5, the corresponding bolt holes are designed as slotted holes. This design allows the outer frame 91 to be flexibly adjusted within a certain range during installation, effectively compensating for manufacturing and assembly errors, ensuring a precise fit between the outer frame 91 and the sleeve 5, and improving overall installation accuracy and efficiency.

[0042] The lower end of the substrate 1 is provided with a drive assembly 3, and the drive rod 31 of the drive assembly 3 corresponds to the upper and lower top block 94 on the collet assembly. The top block 94 is fixedly connected with the collet 95, so that the two work together. The top block 94 and the outer frame 91 are provided with a spring 96. When the drive assembly 3 is in an expanded state, the top block 94 is driven by the drive assembly 3 to move upward and move the collet 95 upward so that the collet is in an open state. At this time, the artificial can place the product to be processed in the collet 95. When the drive assembly 3 is in a retracted state, the spring 96 exerts a downward force on the collet 95 to move the collet 95 in the open state downward, and the collet 95 clamps and fixes the product to be processed in it.

[0043] Specifically, the drive assembly 3 includes a cylinder bracket 32 fixed on the substrate 1, a drive cylinder 33 provided on the cylinder bracket 32, a piston of the drive cylinder 33 fixedly connected with a drive adapter plate 34, and a lower end of the drive rod 31 fixed on the drive adapter plate 34. The substrate 1 is provided with a gap for the drive rod 31 to pass through. The drive cylinder 33 drives the piston to move stably by virtue of the strong air pressure driving capacity, drives the drive rod 31 to move up and down, and cooperates with the spring 96 to realize the opening and closing action of the collet 95.

[0044] In the embodiment, the number of drive rods 31 is two and is distributed at 180 degrees. In this way, it not only ensures uniform and balanced stress and avoids deviation caused by uneven unilateral stress, but also ensures efficient power transmission, so that the top block 94 stably ascends and descends, and the opening and closing state of the collet 95 is accurately controlled, thereby greatly improving the assembly precision and efficiency.

[0045] In the embodiment, the top block 94 is in a ring structure and is sleeved on the support column 8, and plays a key role in connecting the front and the back in the entire collet assembly. A plurality of springs 96 are arranged in a ring array between the top block 94 and the outer frame 91 in a number of at least two, and a highly stable and balanced elastic force transmission network is constructed. The upper end of the spring 96 is fixed on the outer frame 91, and the lower end of the spring 96 is fixed on the top block 94. The effective transmission of force is realized through the above structure.

[0046] When the drive cylinder 33 is expanded, the top block 94 moves upward against the elastic force of the spring 96 and drives the collet 95 to open to adapt to the placement of different specifications of products to be processed; when the drive cylinder 33 is retracted, the spring 96 exerts a downward force on the collet 95 by virtue of its excellent elastic restoring force, so that the opened collet 95 is stably reset and tightly clamped.

[0047] In the embodiment, the outer frame 91 is provided with an outer cover 6 at the upper end, which serves as a protection and auxiliary structure and plays a key role. The opening 61 provided on the outer cover 6 corresponds to the collet 95 in an accurate manner, which not only ensures the normal operation of the collet 95, but also effectively prevents foreign matter from invading and maintains the internal cleanliness.

[0048] The opening 61 is composed of an upper opening 611 and a lower opening 612 arranged coaxially.

[0049] In the embodiment, the outer frame 91 is provided with an annular clamping groove 911, and the screw 7 passes through the outer cover 6 and is embedded into the annular clamping groove 911 to fix the outer cover 6 on the outer frame 91, so that the outer cover 6 is always stable during protection and auxiliary assembly.

[0050] The chuck assembly can be quickly disassembled and replaced from the sleeve, greatly shortening the production conversion time and meeting the clamping requirements of different types of rotating shafts. The chuck clamping action is realized through the double action of the driving assembly and the spring, which complement each other, simplifies the overall structure, reduces the maintenance cost, and improves the assembly efficiency and quality.
