Description

Technical Field

[0001] This utility model relates to the technical field of bow connection mechanism, specifically a bow connection mechanism for a stranding machine. Background Technology

[0002] Currently, the bow connection structure of a single-bow stranding machine includes a connector located on the outside of the rotating shaft. The middle part of the connector is fixed to the rotating shaft, and the two ends of the connector are connected to the bow and a counterweight, respectively. The rotating shaft drives the bow to rotate axially, and the counterweight maintains the dynamic balance of the bow during rotation and the balance of the force on the rotating shaft. However, the connection between the counterweight and the bow is only set at 180° on both sides of the connector, which results in the bow's balance not being optimal after connection.

[0003] In response, Chinese patent application number CN202223133676.7 discloses a bow connection mechanism for a stranding machine, including a rotating shaft. A disc-shaped mounting flange is detachably connected to the outside of the rotating shaft. A fixing plate for connecting the bow is provided on one side of the mounting flange, and a main counterweight is connected to the other side of the mounting flange. Several mounting holes are arranged in a ring around the mounting flange. The mounting holes, fixing plate, and main counterweight are staggered. A fine-tuning counterweight is detachably connected to any one or more mounting holes. This invention enables balance adjustment of the rotating shaft at any circumferential position, thereby improving the rotational stability of the bow.

[0004] This device balances the weight of the drawbar by screwing screws into the mounting holes on the mounting flange surface. However, the mounting holes are circumferentially distributed, and there is a large distance between adjacent sets of mounting holes. In the actual balancing process, the actual installation position of the screws will deviate significantly from the balance position of the drawbar, which will affect the rotational stability of the drawbar.

[0005] Therefore, in order to solve the above problems, a wire stranding machine bow connection mechanism is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a wire drawer connection mechanism for a wire stranding machine, in order to solve the problem mentioned in the background art where the prior art device balances the weight of the wire drawer by screwing screws into the mounting holes on the mounting flange surface. However, the mounting holes are circumferentially distributed, and there is a large distance between adjacent sets of mounting holes. In the actual balancing process, the actual installation position of the screw will be significantly offset from the balance position of the wire drawer, which will affect the rotational stability of the wire drawer.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wire stranding machine bow connection mechanism, comprising: a rotating shaft, an end of which is connected to a mounting flange, a counterweight block connected to the upper surface of the mounting flange, a wire routing hole connected to the middle of the surface of the mounting flange, a guide wheel rotatably mounted on the bottom surface of the wire routing hole, and a fixing plate connected to the lower surface of the mounting flange.

[0008] The outer wall of the mounting flange is provided with a T-slot, and the bottom surface of the mounting flange is provided with a notch;

[0009] A balancing structure is installed on the mounting flange. The balancing structure includes a T-block, which is slidably installed inside the T-slot. A first friction plate is bonded to the outer wall of the T-block. A threaded rod is welded to the middle of the outer wall of the T-block. Positioning pins are provided on both sides of the threaded rod. An abutment block is sleeved on the outer side of the threaded rod. A second friction plate is bonded to the bottom surface of the abutment block. A nut is threadedly connected to the outer side of the threaded rod.

[0010] Preferably, the outer wall of the T-shaped block is in contact with the inner wall of the T-shaped groove, and the first friction piece is in contact with the inner wall of the T-shaped groove.

[0011] Preferably, the upper end of the threaded rod is exposed on the outer wall of the mounting flange via a T-slot.

[0012] Preferably, the bottom surface of the abutment block has a circular hole, and the upper end of the positioning post is inserted into the circular hole.

[0013] Preferably, the positioning post is welded to the outer wall of the T-block.

[0014] Preferably, the abutment block is located on the outside of the mounting flange, the second friction plate is in contact with the outer wall of the mounting flange, and the nut is in contact with the outer wall of the abutment block.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by opening a T-slot on the outer wall of the mounting flange, the T-slot is annular, and the balancing structure can rotate more comprehensively around the outside of the mounting flange within the T-slot, so as to ensure that the position of the balancing structure can make the rotating shaft rotate smoothly and avoid vibration.

[0016] This invention features a balancing structure. A T-block is installed within a notch, and then the T-block is moved until it slides into the inner side of the T-slot. The threaded rod protrudes from the side wall of the mounting flange, and the first friction plate adheres to the inner wall of the T-slot. An abutment block is then fitted onto the outer side of the threaded rod. Moving the abutment block allows the upper end of a positioning pin to be inserted into a circular hole on the bottom surface of the abutment block. The positioning pin, in conjunction with the circular hole, limits the installation angle of the abutment block on the outer side of the threaded rod, ensuring that the angle of the abutment block is the same as the angle of the T-block, thus facilitating the second friction plate to... To maximize the contact area with the outer wall of the mounting flange, the nut is screwed onto the outside of the threaded rod. The surface of the nut abuts against the surface of the abutment block. As the nut continues to rotate, it causes the T-block and the abutment block to move closer together. This allows the first and second friction plates to fit more closely against the inner wall of the T-slot and the outer wall of the mounting flange, increasing the friction between the balancing structure and the mounting flange. This ensures the stability of the balancing structure. Furthermore, since the length of the threaded rod is greater than the thickness of the nut, the dynamic balance of the shaft during rotation can be improved by increasing or decreasing the number of nuts on the outside of the threaded rod.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 The present invention provides an embodiment of a wire winch connection mechanism for a wire winch machine:

[0024] The rotating shaft 1, mounting flange 11, counterweight 12, cable routing hole 13, guide wheel 14 and fixing plate 15 used in this application are products that can be purchased directly on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0025] A wire stranding machine bow connection mechanism includes: a rotating shaft 1, a mounting flange 11 connected to the end of the rotating shaft 1, a counterweight 12 connected to the upper surface of the mounting flange 11, a wire routing hole 13 connected to the middle of the surface of the mounting flange 11, a guide wheel 14 rotatably mounted on the bottom surface of the wire routing hole 13, and a fixing plate 15 connected to the lower surface of the mounting flange 11.

[0026] A T-slot 16 is provided on the outer wall of the mounting flange 11, and a notch 17 is provided on the bottom surface of the mounting flange 11.

[0027] A balancing structure 2 is installed on the mounting flange 11. The balancing structure 2 includes a T-block 21, which is slidably installed inside the T-slot 16. A first friction plate 22 is bonded to the outer wall of the T-block 21. A threaded rod 23 is welded to the middle of the outer wall of the T-block 21. Positioning pins 24 are provided on both sides of the threaded rod 23. An abutment block 25 is sleeved on the outer side of the threaded rod 23. A second friction plate 26 is bonded to the bottom surface of the abutment block 25. A nut 27 is threadedly connected to the outer side of the threaded rod 23. By opening the T-slot 16 on the outer wall of the mounting flange 11, the T-slot 16 is annular. The balancing structure 2 can rotate more comprehensively around the outer side of the mounting flange 11 within the T-slot 16, so as to ensure that the position of the balancing structure 2 can make the rotating shaft 1 rotate smoothly and avoid vibration.

[0028] Furthermore, the outer wall of the T-block 21 is in contact with the inner wall of the T-groove 16, and the first friction plate 22 is in contact with the inner wall of the T-groove 16. The T-block 21 can slide stably in the T-groove 16. The setting of the first friction plate 22 can increase the friction between the T-block 21 and the T-groove 16.

[0029] Furthermore, the upper end of the threaded rod 23 protrudes from the outer wall of the mounting flange 11 via the T-slot 16, and the threaded rod 23 provides a position for the installation of the abutment block 25 and the nut 27.

[0030] Furthermore, a circular hole is provided on the bottom surface of the abutment block 25, and the upper end of the positioning post 24 is inserted into the circular hole. The positioning post 24 cooperates with the circular hole to provide positioning for the abutment block 25 to be installed on the top surface of the T-block 21, so as to prevent the abutment block 25 from rotating when the nut 27 is rotated.

[0031] Furthermore, the positioning post 24 is welded to the outer wall of the T-block 21, and the positioning post 24 provides a limit for the installation of the abutment block 25.

[0032] Furthermore, the abutment block 25 is located on the outside of the mounting flange 11, the second friction plate 26 is attached to the outer wall of the mounting flange 11, and the nut 27 is attached to the outer wall of the abutment block 25. The arrangement of the second friction plate 26 can increase the friction between the abutment block 25 and the mounting flange 11.

[0033] Working principle: During installation, the T-block 21 is installed in the notch 17, and then the T-block 21 is moved so that it slides into the inner side of the T-slot 16. The threaded rod 23 will protrude from the side wall of the mounting flange 11, and the first friction plate 22 will fit against the inner wall of the T-slot 16. The abutment block 25 is fitted onto the outside of the threaded rod 23, and the abutment block 25 is moved so that the upper end of the positioning pin 24 is inserted into the round hole on the bottom surface of the abutment block 25. The positioning pin 24, in conjunction with the round hole, can limit the installation angle of the abutment block 25 outside the threaded rod 23, so that the angle of the abutment block 25 is the same as the angle of the T-block 21, so that the second friction plate 26 can be positioned at the same angle. The largest area is in contact with the outer wall of the mounting flange 11. The nut 27 is screwed onto the outside of the threaded rod 23. The surface of the nut 27 will abut against the surface of the abutment block 25. As the nut 27 continues to rotate, it will drive the T-shaped block 21 and the abutment block 25 to move closer to each other. This will cause the first friction plate 22 and the second friction plate 26 to fit closer to the inner wall of the T-shaped groove 16 and the outer wall of the mounting flange 11. This will increase the friction between the balance structure 2 and the mounting flange 11, making the installation of the balance structure 2 stable. Furthermore, the length of the threaded rod 23 is greater than the thickness of the nut 27. By increasing or decreasing the number of nuts 27 on the outside of the threaded rod 23, the dynamic balance of the rotating shaft 1 during rotation can also be improved.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
