Description

Technical Field

[0001] This utility model relates to the field of braiding machine technology, and in particular to a positioning fixture for a braiding machine guide mold. Background Technology

[0002] High-speed braiding machines are commonly used braiding equipment for cables, mainly used to braid metal wires such as copper wire and aluminum wire, and to braid the fine metal wires into cables.

[0003] This type of braiding machine uses a mold to wrap and wind cables and aluminum foil into a complete cable. It feeds from the bottom and then extends from the top to wind the wrapping layer, finally forming the cable.

[0004] The die at the bottom of the braiding machine that restricts the feeding is called the lower eyelet die. Its function is to pre-form the aluminum foil, making it easier to wrap around the surface of the wire. Lower eyelet dies come in various sizes and need to be locked onto the mounting plate at the bottom of the braiding machine. Because the bottom of the braiding machine needs to wind the cable, both the aluminum foil and the metal wire must be fed and guided through the lower eyelet die. Above the lower eyelet die is the upper eyelet die, which determines the direction of the cable's extension. Other covering materials need to be wound around the upper eyelet die to wrap both the cable and the aluminum foil. Therefore, the lower eyelet die needs to be installed near the center of the braiding machine for easy wrapping.

[0005] Depending on the cable model, different sizes of lower eyelet dies need to be replaced or installed for matching production. However, the location of the lower eyelet dies makes their installation quite inconvenient. The space of the lower eyelet dies mounting plate in the center of the braiding machine is narrow, and the wrench will interfere with other winding devices, making it impossible to use a wrench to hold them. They can only be turned by hand. The lower eyelet dies are smooth cylinders, making it difficult to apply force with either a wrench or by hand. It is also very difficult to turn the knob when the hand is inside the equipment, making the installation of the lower eyelet dies even more difficult.

[0006] The braiding machine vibrates at a high frequency during operation. If the lower eyelet is not tightened or not tightened properly, it is easy for the lower eyelet to loosen and detach during cable operation and winding, causing it to fall off the base plate of the braiding machine. If it does not fall off, the threads will loosen on their own due to vibration, causing the lower eyelet to tilt off the base plate of the braiding machine, affecting the angle of aluminum foil feeding and discharging, and adversely affecting the wrapping of aluminum foil and cable.

[0007] Based on this, this utility model designs a positioning fixture for a braiding machine guide mold to solve the above problems. Utility Model Content

[0008] The purpose of this invention is to provide a positioning fixture for a guide mold of a braiding machine. This device no longer connects the braiding mold to the equipment base plate via threads. Instead, a positioning cylinder is pre-installed. The positioning cylinder is locked to the equipment base plate via threads through a locking cylinder. A knob hole is added, allowing a long rod to be inserted into the knob hole to apply force, thus facilitating the rotation of the positioning cylinder. This ensures that the positioning cylinder is stably locked onto the equipment base plate. The braiding mold is held in place by a magnetic ring inside the positioning cylinder, making it easy to replace and simple to operate. Moreover, there is no need to consider the installation position of the braiding mold. The magnetic ring automatically and tightly holds the braiding mold into place, ensuring accurate positioning.

[0009] This utility model is implemented as follows: a positioning fixture for a braiding machine guide mold, comprising:

[0010] Magnetic ring, positioning cylinder, locking cylinder, and weaving mold;

[0011] The magnetic ring is a ring-shaped strong magnetic sheet;

[0012] The positioning cylinder is a cylindrical sleeve with openings at the top and bottom. Multiple knob holes are provided on the side wall of the positioning cylinder, and every two knob holes are symmetrically arranged on the side wall of the positioning cylinder.

[0013] A locking cylinder is fixed at the top of the positioning cylinder. The locking cylinder is a sleeve with threads on its outer wall. The positioning cylinder and the locking cylinder are an integral structure.

[0014] The inner cylinder of the locking cylinder and the inner cylinder of the positioning cylinder form a stepped hole, and the magnetic ring is stably set at the top of the inner hole of the positioning cylinder. The magnetic ring is snapped into the step between the positioning cylinder and the locking cylinder.

[0015] The weaving mold is a mold covered with aluminum foil on a weaving machine. The weaving mold is cylindrical and is stably adsorbed into the positioning cylinder by a magnetic ring.

[0016] Furthermore, there are four knob holes, which are evenly distributed on the side wall of the positioning cylinder.

[0017] Furthermore, the axis of each of the knob holes is on the same plane, and the axes of every two symmetrically arranged knob holes are on the same straight line;

[0018] Furthermore, each of the aforementioned knob holes has the same diameter, and each of the aforementioned knob holes penetrates laterally through the side wall of the positioning cylinder.

[0019] Furthermore, the magnetic ring is fixedly bonded to the step between the positioning cylinder and the locking cylinder;

[0020] The vertical axes of the positioning cylinder and the locking cylinder coincide.

[0021] Furthermore, the aperture of the positioning cylinder is the same as the outer ring diameter of the magnetic ring;

[0022] The inner diameter of the braiding mold is smaller than the inner diameter of the magnetic ring.

[0023] Furthermore, the weaving mold and the positioning cylinder are in clearance fit, and the lower end of the weaving mold extends below the positioning cylinder, that is, the length of the weaving mold is greater than the inner hole depth of the positioning cylinder.

[0024] The beneficial effects of this utility model are: 1. This device adds a positioning cylinder, and the top of the positioning cylinder is connected to a locking cylinder. The positioning cylinder is installed and locked to the mounting base plate of the equipment through the locking cylinder. After locking, the positioning cylinder does not need to be disassembled. It is easy to install, the positioning is accurate, and the non-disassembly structure makes the fit tighter and more stable.

[0025] 2. The positioning cylinder of this device is also equipped with a knob hole. By cooperating with the long rod and the knob hole, the positioning cylinder can be rotated easily without the need for wrenches or other tools. At the same time, because the long rod can reach a far distance, it can avoid constantly reaching into the equipment with your hands, making the installation of the positioning cylinder more convenient.

[0026] 3. This device also includes a magnetic ring, which is bonded between the positioning cylinder and the locking cylinder. This allows for convenient positioning of the braiding mold. The magnetic ring also facilitates easy disassembly and assembly, enabling faster mold replacement. During installation, simply pull out the mold. Operation and installation are more convenient and simpler. Furthermore, the magnetic ring's positioning ensures that the braiding mold and the magnetic ring's end face are in close contact, preventing the mold from tilting due to equipment vibration and ensuring accurate guidance of the cable and aluminum foil braiding.

[0036] Please see Figures 1 to 6 As shown, this utility model provides a positioning fixture for a guide mold of a braiding machine. In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] In a specific embodiment of the technical solution of this utility model:

[0038] Includes magnetic ring 1, positioning cylinder 2, locking cylinder 21, and weaving mold 3;

[0039] Magnetic ring 1 is a ring-shaped strong magnetic sheet;

[0040] The positioning cylinder 2 is a cylindrical sleeve with openings at the top and bottom. Multiple knob holes 22 are opened on the side wall of the positioning cylinder 2, and every two knob holes 22 are symmetrically arranged on the side wall of the positioning cylinder 2.

[0041] There are four knob holes 22, which are evenly distributed on the side wall of the positioning cylinder 2.

[0042] Furthermore, the axis of each knob hole 22 is on the same plane, and the axes of every two symmetrically arranged knob holes 22 are on the same straight line;

[0043] Furthermore, each knob hole 22 has the same diameter, and each knob hole 22 penetrates the side wall of the positioning cylinder 2 laterally, so that a long rod can be inserted into the two opposite knob holes 22. In this way, the positioning cylinder 2 can be rotated by rotating the long rod, making the operation simpler and eliminating the need for additional large tools. The rotation of the long rod is less likely to affect other devices. Alternatively, a small screwdriver can be inserted into the knob hole 22 to rotate the positioning cylinder 2.

[0044] A locking cylinder 21 is fixed at the top of the positioning cylinder 2. The locking cylinder 21 is a sleeve with threads on its outer wall. The positioning cylinder 2 and the locking cylinder 21 are an integral structure.

[0045] The locking cylinder 21 and the inner cylinder of the positioning cylinder 2 form a stepped hole. The magnetic ring 1 is stably set at the top of the inner hole of the positioning cylinder 2. The magnetic ring 1 is snapped into the step between the positioning cylinder 2 and the locking cylinder 21.

[0046] The magnetic ring 1 is fixedly bonded to the step between the positioning cylinder 2 and the locking cylinder 21;

[0047] The vertical axes of the positioning cylinder 2 and the locking cylinder 21 coincide, making this step the positioning point of the magnetic ring 1. This facilitates the positioning and magnetic attraction of the braiding mold 3, ensuring accurate positioning and accurate guidance of the cable and aluminum foil.

[0048] The braiding mold 3 is a mold covered with aluminum foil on the braiding machine. The braiding mold 3 is cylindrical and is stably adsorbed into the positioning cylinder 2 by the magnetic ring 1.

[0049] The braiding mold 3 and the positioning cylinder 2 are in clearance fit. The braiding mold 3 is the lower eyelet mold of the braiding machine. The lower end of the braiding mold 3 extends below the positioning cylinder 2, that is, the length of the braiding mold 3 is greater than the inner hole depth of the positioning cylinder 2.

[0050] The diameter of the positioning cylinder 2 is the same as the outer ring diameter of the magnetic ring 1, and the inner diameter of the magnetic ring 1 is larger than the inner diameter of the locking cylinder 21; the inner diameter of the braiding mold 3 is smaller than the inner diameter of the magnetic ring 1, which facilitates the smooth installation, docking or removal and replacement of the braiding mold 3 inside the positioning cylinder 2, and the magnetic ring 1 does not affect the cable travel in the inner hole of the braiding mold 3.

[0051] During installation, the positioning cylinder 2 is first aligned with the threaded hole on the base plate of the original equipment. The locking cylinder 21 is then locked to the base plate of the braiding machine through the external thread. At the same time, a long rod is inserted into the two symmetrical knob holes 22. Rotating the long rod will rotate the positioning cylinder 2, thereby stabilizing its installation.

[0052] The torque can be increased by using a long rod to ensure a tight fit of the positioning cylinder 2. Furthermore, the long rod can be inserted into the equipment without manual intervention, making operation more convenient.

[0053] After ensuring that the locking cylinder 21 is locked to the equipment, the braiding mold 3 can be installed. The magnetic ring 1 is itself bonded and fixed to the top of the inner cavity of the positioning cylinder 1. The magnetic ring 1 is positioned through the stepped hole. The installation of the braiding mold 3 only requires aligning it with the bottom opening of the positioning cylinder 2 and pushing it. The braiding mold 3 itself is made of stainless steel and has strong magnetic properties, ensuring stable adsorption.

[0054] Disassembly is also very convenient; simply pull out the braiding mold 3. Replacement is very easy, without needing to disassemble or reassemble the threads. The connection is also more stable, as the magnetic ring 1 will adhere and attract the top end face of the braiding mold 3, ensuring accurate connection direction. It is simple to use. Moreover, even if the braiding mold 3 originally has threads, it does not need to be replaced, and the same equipment end does not need to be modified. Only the positioning cylinder 2 needs to be added to complete the equipment modification.

[0055] Furthermore, in the description of this utility model, the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0056] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
