[0015] Figure 4 for Figure 3 AA section view. DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] Reference Figure 1-4 The present specific implementation adopts the following technical scheme: it includes a fixture body 1, a first support block 2, a positioning reference seat 3, a mold-changing support block 4, a threaded pull rod 5, a second support block 6, a center pull rod 7, a first stroke adjustment block 8, a link body 9, a second stroke adjustment block 10 and an expansion sleeve 11. The first stroke adjustment block 8 is connected to the center pull rod 7 through the second stroke adjustment block 10. The thread on the center pull rod 7 is screwed to the threaded pull rod 5. The threaded pull rod 5 is positioned and matched with the positioning reference seat 3. The positioning reference seat 3 is fixed between the fixture body 1 and the link body 9. The top of the threaded pull rod 5 is connected to the expansion sleeve 11. A second support block 6 is arranged in the center of the positioning reference seat 3. The second support block 6 is connected to the first support block 2 through the mold-changing support block 4. A processed part 12 is placed on the first support block 2, and the outer wall of the processed part is clamped and matched with the expansion sleeve 11.

[0018] The upper portion of the outer wall of the expansion sleeve 11 is tilted outward, and the upper portion of the inner wall of the clamp body 1 is also tilted outward. The outer wall of the expansion sleeve 11 is in top contact with the inner wall of the clamp body 1, and the lower portion of the expansion sleeve 11 and the lower portion of the inner wall of the clamp body 1 are both axially parallel to the center pull rod 7.

[0019] It is worth noting that the upper end of the threaded pull rod 5 is plug-fitted into the hole in the positioning reference seat 3 .

[0020] It is worth noting that the lower outer ring of the link body 9 is provided with a mounting thread 91 .

[0021] In addition, the center of the processed part 12 is also fixed to the first support block 2 by a fastening bolt 13 .

[0022] This specific implementation method adjusts the moving distance of the precise center pull rod 7 through the first stroke adjustment block 8 and the second stroke adjustment block 10, thereby controlling the moving distance of the threaded pull rod. When the center pull rod is pulled downward, the threaded pull rod is driven downward, thereby causing the expansion sleeve to move downward, and the outer part of the upper part of the expansion sleeve moves downward along the inner wall of the fixture body 1, thereby causing the expansion sleeve to shrink and clamp the processed part 12 (middle shell part) for easy processing; conversely, when the center rod moves upward, the expansion sleeve is loosened, and the completed processed part can be disassembled.

[0023] The specific implementation method has a simple structure and a reasonable design. The movement stroke of the center pull rod can be controlled by the first stroke adjustment block and the second stroke adjustment block, thereby controlling the clamping and loosening of the expansion sleeve. The control accuracy is accurate, the parts processing efficiency is high, the loading and unloading speed is fast, and the manufacturing cost is greatly reduced, and the practicability is strong.

[0024] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
