[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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 should fall within the protection scope of this utility model.

[0030] like Figures 1 to 6 As shown, the cutting and weaving fixture in one embodiment of the present invention includes: a base plate 1, a guide assembly 2, and a punching assembly 3.

[0031] like Figures 1 to 2 As shown, the guide assembly 2 is mounted on top of the base plate 1. The guide assembly 2 includes a fixing plate 201, which is fixedly mounted on top of the base plate 1. The fixing plate 201 assembles and fixes the guide member 202.

[0032] The fixing plate 201 has a wire-passing hole. The wire-passing hole provides assembly clearance space for the guide component 202.

[0033] like Figures 4 to 6As shown, a guide 202 is fixedly connected inside the threading hole. The guide 202 guides the threading and braiding, and can also be used for cutting and braiding through the cooperation of the guide 202 and the linkage rod 303.

[0034] It is worth noting that a guide hole is provided within the guide member 202. This guide hole facilitates threading and braiding guidance. The diameter of the guide hole at the end closest to the cutter bar 307 is smaller than the diameter at the other end, improving the smoothness of threading and guidance.

[0035] like Figures 2 to 3 As shown, a pair of reinforcing plates 203 are fixedly connected between the fixing plate 201 and the base plate 1. The pair of reinforcing plates 203 provide auxiliary support for the fixing plate 201, thereby improving the support stability of the fixing plate 201.

[0036] Specifically, a positioning threaded hole is provided on the upper part of the fixing plate 201, and the positioning threaded hole communicates with the wire hole. This facilitates locking and positioning of the guide 202 by installing a positioning bolt in the positioning threaded hole.

[0037] like Figures 2 to 3 As shown, the punching assembly 3 is mounted on one side of the fixed plate 201. The punching assembly 3 includes a punching cylinder 301, which is fixedly mounted on the top of the base plate 1. The movement of the cylinder piston 302 is controlled by controlling the air intake of the punching cylinder 301.

[0038] In practical applications, the punching cylinder 301 can be connected to an external control air source.

[0039] like Figures 2 to 3 As shown, a cylinder fixing plate 309 is fixedly mounted on the top of the base plate 1, and the punching cylinder 301 is fixedly connected to the side of the cylinder fixing plate 309. The punching cylinder 301 is assembled and fixed by the cylinder fixing plate 309. A pair of reinforcing side plates 310 are fixedly connected between the punching cylinder 301 and the base plate 1, and the pair of reinforcing side plates 310 are arranged on both sides of the punching cylinder 301. The pair of reinforcing side plates 310 provide auxiliary support for the cylinder fixing plate 309.

[0040] like Figures 3 to 5 As shown, a cylinder piston 302 is slidably mounted inside the punching cylinder 301. The movement of the cylinder piston 302 is controlled to synchronously move the linkage rod 303.

[0041] like Figures 3 to 5 As shown, the cylinder piston 302 consists of two parts: a piston rod 3021 and a piston block 3022. A cylindrical air chamber matching the piston block 3022 is provided inside the punching cylinder 301. The piston rod 3021 controls the movement of the connecting rod 311.

[0042] like Figures 3 to 5 As shown, a connecting rod 311 is fixedly connected to one end of the piston rod 3021 located outside the punching cylinder 301. The connecting rod 311 connects and limits the piston rod 3021 and the linkage rod 303.

[0043] like Figures 3 to 5 As shown, the piston 302 of the cylinder is engaged with a linkage rod 303 at one end outside the punching cylinder 301. The movement and rotation of the linkage rod 303 synchronously drive the cutting rod 307.

[0044] The linkage rod 303 has a slot at one end close to the connecting rod 311, and the connecting rod 311 is slidably fitted into the slot. The connection between the connecting rod 311 and the linkage rod 303 is limited by fitting the connecting rod 311 into the slot.

[0045] like Figures 2 to 4 As shown, an assembly block 312 is fixedly connected to the base plate 1, and a guide plate 305 is fixedly connected to the side of the assembly block 312. The assembly block 312 provides support and fixation for the guide sleeve 313 and the guide plate 305.

[0046] like Figures 2 to 4 As shown, a limiting through hole is provided in the assembly block 312, and the linkage rod 303 is provided through the limiting through hole. A guide sleeve 313 is fixedly connected in the limiting through hole, and the guide sleeve 313 is sleeved on the outside of the linkage rod 303. The guide sleeve 313 plays a role in assisting in the limiting and guiding of the linkage rod 303.

[0047] like Figures 2 to 5 As shown, a pulley 304 is fixedly connected to the outer side of the linkage 303. The linkage 303 is synchronously driven and controlled by guiding the movement of the pulley 304.

[0048] like Figure 5 As shown, a guide plate 305 is fixedly connected to the top of the base plate 1. A sliding groove 306 is formed in the guide plate 305, and a pulley 304 is slidably assembled in the sliding groove 306. The sliding groove 306 consists of two parts: a horizontal sliding groove and an inclined sliding groove, which are connected to each other. The pulley 304 can slide under the action of the horizontal sliding groove. When the pulley 304 moves along the inclined sliding groove, the linkage rod 303 will rotate at a certain angle as the pulley 304 moves.

[0049] like Figures 2 to 4 As shown, a cutting rod 307 is provided at the other end of the linkage rod 303. The cutting rod 307 is used to limit the installation of the braided tube to be cut. At the same time, the braided tube can be cut by the impact and rotation of the cutting rod 307 in conjunction with the guide member 202.

[0050] Specifically, the outer diameter of the cutting rod 307 and the inner diameter of the guide 202 can be adjusted synchronously according to the wire diameter, which improves the applicability of the cutting and braiding fixture.

[0051] like Figures 3 to 4 As shown, the cutting rod 307 consists of two parts: a fixed rod body 3071 and a cutting rod body 3072. The cutting rod body 3072 is integrally formed at the end of the fixed rod body 3071 that is close to the guide member 202. The length of the collar 308 is greater than the length of the fixed rod body 3071. This allows the collar 308 to fit the fixed rod body 3071 and the linkage rod 303 together, so that the cutting rod 307 can move synchronously with the movement and rotation of the linkage rod 303 under the action of the collar 308 and the fastening ring 314.

[0052] like Figures 3 to 4 A collar 308 is fitted around the outer side of the cutting rod 307 and the linkage rod 303. The collar 308 consists of two parts: a fixed collar 3081 and multiple contracting arc plates 3082. The multiple contracting arc plates 3082 are integrally formed on one side of the fixed collar 3081, and the multiple fixed collars 3081 cooperate to form a contraction gap. By shrinking with the contraction gap, the multiple contracting arc plates 3082 can clamp and fix the fixed rod body 3071.

[0053] like Figures 2 to 3 As shown, a fastening ring 314 is fitted on the outer side of the collar 308, and a locking bolt 315 is threaded onto the fastening ring 314. By controlling the rotation of the locking bolt 315, the fastening ring 314 can fasten the collar 308.

[0054] like Figure 6 As shown, a protective sleeve 316 is fixedly mounted on the top of the base plate 1. The protective sleeve 316 is fitted onto the outside of the assembly block 312 and the cylinder fixing plate 309. The protective sleeve 316 provides protection for the assembly block 312, the cylinder fixing plate 309, the linkage rod 303, the pulley 304, the guide plate 305, and the punching cylinder 301.

[0055] In practical use, the braided tube to be cut can be inserted along the guide 202 and fitted onto the outside of the cutting rod 3072. When it reaches the cutting length, the cylinder piston 302 can be driven to extend by supplying compressed air into the punching cylinder 301. During the extension of the cylinder piston 302, the linkage rod 303 extends synchronously with the extension of the cylinder piston 302 under the action of the connecting rod 311.

[0056] In this process, the linkage rod 303 is guided to move by the cooperation of pulley 304 and slide groove 306. When pulley 304 moves in the horizontal slide groove, linkage rod 303 is also moving horizontally. When pulley 304 moves along the inclined slide groove, linkage rod 303 will rotate under the action of pulley 304, so that linkage rod 303 is in a moving and rotating state. Through the impact rotation of linkage rod 303 and the cooperation of guide 202, the braided tube to be cut can be cut.

[0057] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0058] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
