The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0017] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0018] Please see Figure 1-3 This utility model provides a technical solution: an axial positioning device for a wire drawing machine shaft assembly, including a wire drawing machine drive shaft 1, a drive gear 2 at the output end of the drive shaft 1, an installation groove 3 inside the drive gear 2, the interior of the installation groove 3 being slidably adapted to the output end of the drive shaft 1, an axial positioning groove 4 at the output end of the drive shaft 1, a positioning locking assembly on the outer surface of the drive shaft 1, the positioning locking assembly including a circular cover plate 8, the interior of the circular cover plate 8 being slidably sleeved with the output end of the drive shaft 1, the circular cover plate 8 being located on one side of the drive gear 2, two positioning rods 7 being fixedly connected to one end of the circular cover plate 8, a fixing ring 9 being fixedly installed on the side of the circular cover plate 8 away from the positioning rods 7, two positioning holes 6 being opened inside the drive gear 2, the two positioning holes 6 being located on the upper and lower sides of the installation groove 3 respectively, and the interiors of the two positioning holes 6 being slidably connected to the outer surfaces of the two positioning rods 7 respectively.

[0019] Furthermore, the inside of the fixed ring 9 is slidably sleeved with the output end of the wire drawing machine drive shaft 1, and a positioning plate 13 is fixedly installed inside the fixed ring 9. The outer surface of the positioning plate 13 is slidably connected with the inside of the axial positioning groove 4.

[0020] Furthermore, circular holes 5 are provided on both sides of the output end of the wire drawing machine drive shaft 1, and the two circular holes 5 are respectively connected to the interior of the axial positioning groove 4.

[0021] Furthermore, a first threaded groove 10 is provided on both sides of the fixing ring 9, and the interior of the two first threaded grooves 10 is connected to the interior of the fixing ring 9 respectively. A locking bolt 11 is threadedly connected to the interior of the two first threaded grooves 10.

[0022] Furthermore, the positioning plate 13 has second threaded grooves 12 on both sides, and the opposite ends of the two locking bolts 11 pass through the interior of the corresponding circular holes 5, and the opposite ends of the two locking bolts 11 are respectively threaded into the interior of the corresponding second threaded grooves 12.

[0023] Furthermore, during the assembly stage, the transmission gear 2 is fitted onto the output end of the wire drawing machine drive shaft 1 through its internal mounting groove 3, allowing them to slide and adapt, thus initially completing the installation of the transmission gear 2 on the drive shaft. Next, the circular cover plate 8 is fitted onto the output end of the wire drawing machine drive shaft 1, at which point the circular cover plate 8 is located on one side of the transmission gear 2. Since the two positioning rods 7 fixedly connected to one end of the circular cover plate 8 correspond to the positions of the two positioning holes 6 opened inside the transmission gear 2, pushing the circular cover plate 8 causes the positioning rods 7 to insert into the positioning holes 6. This step initially restricts the movement of the transmission gear 2 along the axial direction of the drive shaft, thus playing a pre-positioning role.

[0024] Furthermore, the retaining ring 9 slides along the output end of the transmission shaft, causing the positioning plate 13 to be embedded in the axial positioning groove 4, further strengthening the limitation of the axial position of the transmission gear 2. At this time, the relative position of the retaining ring 9 and the transmission shaft is also initially determined.

[0025] Furthermore, finally, locking bolts 11 are screwed into the first threaded grooves 10 on both sides of the fixed ring 9. Since the circular holes 5 on both sides of the output end of the wire drawing machine drive shaft 1 are connected to the axial positioning groove 4, and the second threaded grooves are provided on both sides of the positioning plate 13, the locking bolts 11 are rotated so that their opposite ends pass through the circular holes 5 and are screwed into the second threaded grooves 12. By tightening the locking bolts 11, the fixed ring 9, the positioning plate 13 and the drive shaft are tightly connected, and the drive gear 2 is firmly fixed at the output end of the drive shaft, thus completing the axial positioning work.

[0026] Furthermore, through the coordinated arrangement of the positioning plate 13, the axial positioning groove 4, the positioning rod 7, and the positioning hole 6, the transmission gear 2 can be conveniently axially installed and positioned on the wire drawing machine transmission shaft 1, thereby effectively preventing the transmission gear 2 from moving axially along the wire drawing machine transmission shaft 1. This ensures that the transmission gear 2 stably transmits power, guarantees the stability and reliability of the wire drawing machine shaft assembly, reduces equipment wear and failures caused by axial displacement, improves the overall working performance of the wire drawing machine, and further enhances the practicality of the positioning device.

[0027] Structural Description: Wire drawing machine drive shaft 1: As the core of power transmission for the entire shaft assembly, it is the carrier connecting the power source and the working parts such as the transmission gear 2. It is responsible for transmitting the rotational power of the power source to the transmission gear 2, providing the power foundation for the operation of the wire drawing machine. Its structural strength and stability directly affect the working performance of the shaft assembly.

[0028] Transmission gear 2: It slides and adapts to the output end of the wire drawing machine transmission shaft 1 through the internal mounting groove 3 to achieve connection with the transmission shaft. In the shaft assembly, it plays an important role in changing the direction and speed of power transmission, and transmits the power of the transmission shaft to the subsequent working parts. It is a key link in the power transmission system of the wire drawing machine.

[0029] Mounting slot 3: It is opened inside the transmission gear 2 and forms a sliding fit structure with the output end of the wire drawing machine transmission shaft 1. This design facilitates the installation and removal of the transmission gear 2 on the transmission shaft, and at the same time, it can perform preliminary radial positioning of the transmission gear 2 to a certain extent to ensure its coaxiality with the transmission shaft.

[0030] Axial positioning groove 4: It is set at the output end of the wire drawing machine drive shaft 1 and cooperates with the positioning plate 13 in the positioning and locking assembly. The sliding connection between the two realizes the precise limitation of the axial position of the transmission gear 2 and provides a stable axial positioning reference for the transmission gear 2.

[0031] Circular hole 5: Located on both sides of the output end of the wire drawing machine drive shaft 1 and connected to the inside of the axial positioning groove 4. Its function is to provide a through channel for the locking bolt 11, so that the locking bolt 11 can pass through the circular hole 5 from the outside of the drive shaft and connect with the second threaded groove 12 on the positioning plate 13, thereby realizing the fastening of the positioning locking assembly.

[0032] Positioning hole 6: Inside the transmission gear 2, located on the upper and lower sides of the mounting groove 3, it is slidably connected to the positioning rod 7 on the circular cover plate 8. By inserting the positioning rod 7 into the positioning hole 6, the transmission gear 2 is initially positioned axially, restricting its movement in the axial direction.

[0033] Positioning rod 7: It is fixedly connected to one end of the circular cover plate 8 and is set to correspond to the positioning hole 6 on the transmission gear 2. After being inserted into the positioning hole 6, it can pre-position the transmission gear 2 and prevent it from moving axially during installation.

[0034] Circular cover plate 8: It is slidably sleeved with the output end of the wire drawing machine drive shaft 1 and is located on one side of the drive gear 2. As a component of the positioning and locking assembly, the positioning rod 7 at one end cooperates with the positioning hole 6 on the drive gear 2 to achieve pre-positioning, and the other end is connected to the fixing ring 9, integrating the positioning and locking functions to enhance the positioning effect.

[0035] Fixed ring 9: It is slidably sleeved with the output end of the wire drawing machine drive shaft 1. The positioning plate 13 fixedly installed inside it cooperates with the axial positioning groove 4 to perform secondary axial positioning of the transmission gear 2. At the same time, the first threaded grooves 10 on both sides of the fixed ring 9 are used to install locking bolts 11 to achieve the fastening of the entire positioning and locking assembly.

[0036] First threaded groove 10: It is formed on both sides of the fixed ring 9 and communicates with the inside of the fixed ring 9. It is used to connect with the locking bolt 11 by thread. By tightening the locking bolt 11, the fixed ring 9, the positioning plate 13 and the transmission shaft are tightly connected, which enhances the stability and reliability of the positioning device.

[0037] Locking bolt 11: Screwed into the first threaded groove 10 on both sides of the fixing ring 9, and its opposite ends pass through the circular hole 5 at the output end of the wire drawing machine drive shaft 1 and are threadedly connected to the second threaded groove 12 on both sides of the positioning plate 13. The positioning locking assembly is firmly connected to the drive shaft by the threaded fastening method to ensure the axial positioning effect of the transmission gear 2.

[0038] The second threaded groove 12 is located on both sides of the positioning plate 13 and cooperates with the locking bolt 11 to provide a threaded connection structure for the locking bolt 11, so that the locking bolt 11 can tightly fix the positioning plate 13, the fixing ring 9 and the drive shaft together.

[0039] Positioning plate 13: It is fixedly installed inside the fixing ring 9. Its outer surface is slidably connected to the axial positioning groove 4 at the output end of the wire drawing machine drive shaft 1. Through this cooperation, the axial position of the transmission gear 2 is further limited. At the same time, it is connected to the locking bolt 11 to realize the combination of positioning and locking functions.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
