[0006] The end cover is a circular ring structure, has the same diameter as the circular structure surrounded by the clamping block, and is provided with a threaded hole matching the threaded hole on the upper end surface of the clamping block and the clamping channel;

[0007] A clamping bolt connects the end cover to the clamping block and clamps the processed part in the clamping channel.

[0008] In a preferred solution, eight clamping blocks are provided and eight clamping channels are also provided.

[0009] In a preferred solution, the base of the clamp seat is connected to a three-jaw chuck, the base is provided with a clamping block, and the three-jaw chuck is detachably connected to the base via the clamping block.

[0010] In a preferred solution, the head of the clamping bolt is hexagonal or octagonal.

[0011] In a preferred solution, the clamping blocks form a circular structure with a detachable positioning cylinder installed inside, so that the ends of all processed parts are aligned with the surface of the positioning cylinder, ensuring that all processed parts have the same rotation center.

[0012] The beneficial effects achieved by the utility model are:

[0013] First, the utility model designs a clamping seat composed of a circular base and a plurality of arc-shaped clamping blocks, and a clamping channel is provided between adjacent clamping blocks, which can clamp and load turned parts in batches, and can process multiple parts at the same time, thereby improving the efficiency and accuracy of batch processing of CNC lathes, and simplifying the operation process, making the fixture more practical and efficient.

[0014] Second, the design of the three-jaw chuck allows for quick loading and unloading, and the block design of the base allows the three-jaw chuck to be detachably connected to the base, making operation and maintenance easier.

[0015] Third, the head of the clamping bolt is designed to be an inner hexagon or an inner octagon, so that the clamping bolt is easy to operate with tools, thereby improving the practicality and convenience of operation of the clamp.

[0016] Fourth, a removable positioning cylinder is installed inside the circular structure surrounded by the clamping blocks, which ensures the precise positioning of the processed parts, guarantees the processing accuracy and processing quality, and also facilitates the replacement of parts during batch processing.
