[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] In addition, to clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The top, bottom, left, right, front, and back sides are shown.

[0020] like Figures 1 to 3As shown, the present application provides a full-open clamping assembly. The clamping assembly comprises a first clamping piece 1 and a second clamping piece 2, a plurality of alignment components 3, a plurality of locking components 4, and a hot sleeve assembly 5.

[0021] Specifically, the first clamping piece 1 and the second clamping piece 2 are detachably connected, and after assembly, they form a circular mounting hole. The alignment components 3 are arranged at the left and right ends of the first clamping piece 1 and the second clamping piece 2, and are fixedly connected or integrally formed with the first clamping piece 1 and the second clamping piece 2, for realizing the positioning connection of the first clamping piece 1 and the second clamping piece 2, to ensure the positional consistency between the two clamping pieces, avoid installation deviation, and ensure the structural symmetry and stability. The locking components 4 are arranged on the alignment components 3, for locking the first clamping piece 1 and the second clamping piece 2, to enhance the structural strength and reliability of the whole. The hot sleeve assembly 5 comprises a punching sheet 51 and a pressing plate 52. The punching sheet 51 is arranged in the mounting hole and is arranged in close contact with the inner wall of the first clamping piece 1 and the second clamping piece 2, and realizes thermal expansion or contraction fixation through the material characteristics. The pressing plate 52 is detachably arranged on the top of the first clamping piece 1 and the second clamping piece 2, and at least part of the pressing plate 52 is arranged in the mounting hole and abuts against the punching sheet 51, to limit the axial movement of the punching sheet 51 and ensure that the punching sheet 51 will not be displaced due to vibration or external force during use.

[0022] Through the above arrangement, the full-open clamping assembly realizes a modular and detachable structure, which is convenient for installation, maintenance and replacement. The cooperation of the alignment components 3 and the locking components 4 provides high-precision assembly effect, ensuring the stability and safety during use. The hot sleeve assembly 5 improves the connection fastening force through physical pressure connection, which helps to prevent the punching sheet 51 from loosening, and at the same time, the structure of the pressing plate 52 also simplifies the operation steps and improves the work efficiency. The close cooperation between the circular mounting hole and the punching sheet 51 effectively improves the clamping accuracy, so that the whole system is suitable for application scenarios with high clamping accuracy requirements.

[0023] As shown in the Figure 2 The alignment components 3 are provided with a plurality of positioning holes 31 in the front-rear direction, and the locking components 4 are positioning pins. The locking components 4 pass through the positioning holes 31 to lock the first clamping piece 1 and the second clamping piece 2. By adopting the structure of the positioning hole 31 and the positioning pin, the clamping assembly has the advantages of stable connection, accurate positioning, and convenient assembly and disassembly, and is especially suitable for clamping application scenarios that need to be frequently disassembled or have high positioning accuracy requirements.

[0024] The first clamping piece 1 and the second clamping piece 2 are provided with a limiting portion 11 around the bottom of the inner wall, which cooperates with the pressing plate 52 to limit the movement of the punching sheet 51 along its own axis, which can effectively prevent the punching sheet 51 from producing axial displacement under the action of thermal expansion or external force, thereby ensuring the stability and reliability of the hot sleeve structure.

[0025] As shown in the Figure 3As shown, the difference between the outer diameter of the punch 51 and the diameter of the mounting hole is greater than or equal to 0.06mm and less than or equal to 0.4mm, so as to ensure the smooth installation of the punch 51 and the pressing plate 52, and also prevent the structural looseness caused by the excessively large installation gap, thereby improving the stability and reliability of the overall system.

[0026] As shown in Figure 3 and Figure 4 The pressing plate 52 comprises a pressing portion 521 and a connecting portion 522, the connecting portion 522 is arranged around the pressing portion 521, and the pressing portion 521 is fixedly connected or integrally formed with the connecting portion 522. The connecting portion 522 is fixedly connected with the top of the first clamping piece 1 and the second clamping piece 2, respectively. Through the above arrangement, the precise pressing of the punch 51 is realized, and the overall assembly and maintenance are facilitated.

[0027] Further, the pressing plate 52 further comprises a fastening bolt 523. The connecting portion 522 is provided with a plurality of through holes 524, and the top of the first clamping piece 1 and the second clamping piece 2 is correspondingly provided with a threaded hole 12, and the fastening bolt 523 is connected with the threaded hole 12 through the through hole 524, so as to fix the pressing plate 52 to the first clamping piece 1 and the second clamping piece 2. The above structure can uniformly and stably apply the pressing force to the surface of the punch 51, so as to prevent the axial displacement or warping of the punch 51, and further improve the fastening effect and stability of the hot-jacket assembly 5.

[0028] As shown in Figure 2 The first clamping piece 1 and the second clamping piece 2 are provided with a chamfer 13 around the top of the inner wall, which can help the punch 51 and the pressing plate 52 to be automatically centered and guided into the hole, thereby improving the assembly efficiency and accuracy. The chamfer 13 can also slow down the structural fatigue caused by local stress concentration, and improve the overall life of the clamping assembly.
