DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] like Figures 1 to 6 As shown, a commutator hook mold includes a base 1, a support platform 2 and a pressing mechanism, wherein the base 1 is fixedly arranged on a workbench 7, a mounting hole 11 is arranged inside the base 1, and a commutator body 3 is placed in the mounting hole 11; a threaded column 21 is arranged at the bottom of the support platform 2, and the threaded column 21 is threadedly connected to the inner wall of the mounting hole 11, a socket 22 is arranged between the support platform 2 and the threaded column 21, and the commutator body 3 is arranged in the socket 22, and a plurality of hooks 31 are arranged on the top of the commutator body 3, and the hooks 31 are placed on the top of the support platform 2, and the pressing mechanism is arranged above the hooks 31 to flatten the hooks 31; a clamping mechanism is arranged at the bottom of the base 1.

[0030] First, place the commutator body 3 into the mounting hole 11 of the base 1, and the support platform 2 is threadedly connected to the inner wall of the mounting hole 11 through the bottom threaded column 21, so that the commutator body 3 is placed in the socket 22 of the support platform 2 for easy placement. The height of the support platform 2 can be adjusted through the threaded cooperation between the threaded column 21 and the mounting hole 11 to adapt to commutator bodies 3 of different lengths, ensuring that the bent hook 31 at the top of the commutator body 3 can be accurately located at the top of the support platform 2, thereby improving the versatility and flexibility of the device, enabling it to meet the whole hook processing requirements of commutators of various specifications, reducing the processing errors and equipment adjustment time caused by differences in commutator sizes, and improving production efficiency and product quality.

[0031] The sheet pressing mechanism includes a mounting frame 4, a telescopic motor 41 and a pressing plate 43. The bottom of the mounting frame 4 is fixedly arranged on the workbench 7. The side wall of the mounting frame 4 is provided with a horizontal plate 42. The top of the horizontal plate 42 is provided with the telescopic motor 41. The output end of the telescopic motor 41 passes through the horizontal plate 42 and is connected to the pressing plate 43. The pressing plate 43 is located above the hook 31.

[0032] The telescopic motor 41 is fixed on the horizontal plate 42 of the side wall of the mounting frame 4. When the telescopic motor 41 receives the working signal, its output end generates telescopic movement, driving the pressing plate 43 connected to the output end to move up and down. Since the pressing plate 43 is located above the hook 31, the hook 31 is flattened by downward pressure, and the precise control ability of the motor is used to achieve precise control of the flattening force and stroke, thereby improving the work efficiency and flattening accuracy, avoiding the problem of inconsistent flattening caused by human factors, ensuring the stability of product quality, and reducing the labor intensity of operators.

[0033] The clamping mechanism includes a screw rod 5, a first bevel gear 51 and a rotary motor 6. The base 1 is provided with an escape opening 12 around it. The workbench 7 is provided with a slide groove 71, which extends along the escape opening 12 toward the center of the base 1. The screw rod 5 is provided in the slide groove 71. The first bevel gear 51 is provided at one end of the screw rod 5 close to the center of the base 1. The rotary motor 6 is provided at the bottom of the workbench 7. The output end of the rotary motor 6 is connected to a second bevel gear 61, which meshes with the first bevel gear 51. The screw rod 5 is provided with a clamping ring 52, which is provided around the base 1 to clamp the outer peripheral wall of the commutator body 3. The first bevel gear 51 and the second bevel gear 61 are located inside the workbench 7.

[0034] The rotating motor 6 drives the second bevel gear 61 to rotate. Since the second bevel gear 61 meshes with the first bevel gear 51, the first bevel gear 51 will rotate accordingly, thereby driving the screw 5 connected thereto to rotate. The clamping ring 52 on the screw 5 is threadedly connected to the screw 5. According to the transmission principle of the screw 5, when the screw 5 rotates, the clamping ring 52 will move in the slide groove 71 of the workbench 7, thereby clamping or loosening the outer peripheral wall of the commutator body 3, ensuring that the commutator body 3 will not be displaced or shaken during the processing, thereby ensuring the processing accuracy and stability. This clamping mechanism driven by the bevel gear and the screw 5 has high clamping accuracy and reliability, can adapt to commutator bodies 3 of different sizes, and improves the versatility of the equipment.

[0035] The outer wall of the support platform 2 is provided with friction lines 23. The friction lines 23 facilitate the adjustment of the height of the threaded column 21 relative to the base 1. Improve work efficiency,

[0036] A limiting ring 8 is disposed on the top of the avoidance opening 12 of the base 1 , and the limiting ring 8 is located at the bottom of the threaded column 21 .

[0037] When the rotating motor 6 drives the clamping ring 52 to move and clamp the commutator body 3, if there is no limit ring 8, the threaded column 21 may be in a lower position due to the rotation adjustment of the support platform 2, thereby blocking the moving path of the clamping ring 52. The limit ring 8 is located at the bottom of the threaded column 21. When the threaded column 21 is adjusted downward to a certain extent, it will be blocked by the limit ring 8 and cannot continue to descend, thereby ensuring that the threaded column 21 will not enter the moving area of ​​the clamping ring 52, avoiding obstruction to the clamping ring 52.

[0038] The size of the socket 22 is larger than the outer circumference of the commutator body 3. Since the size of the socket 22 is larger than the outer circumference of the commutator body 3, the commutator body 3 can be easily placed in the socket 22 of the support table 2, which is convenient for installation and positioning. During the processing, even if the commutator body 3 is subjected to a certain external force such as the pressure of the sheet pressing mechanism, the gap between the socket 22 and the commutator body 3 can provide a certain buffer space to prevent the commutator body 3 from being damaged due to excessive extrusion, and it is also convenient to remove the commutator body 3 after the processing is completed.

[0039] The base 1 is fixedly mounted on the workbench 7 by bolts. The stability of the base 1 on the workbench 7 is ensured, providing a reliable foundation for the normal operation of the entire commutator hook mold. The processing error and equipment failure caused by the instability of the base 1 are reduced, the reliability and processing accuracy of the equipment are improved, and the installation and disassembly of the equipment are also convenient for maintenance and overhaul.

[0040] A positioning plate 9 is provided at the bottom of the mounting frame 4, and the positioning plate 9 is fixedly provided on the workbench 7 by bolts. The installation accuracy of the sheet pressing mechanism is improved, and the relative position between the pressing plate 43 and the hook 31 of the commutator body 3 is ensured to be accurate, thereby improving the accuracy and quality of the flattening of the hook 31. The stable position of the mounting frame 4 also reduces the vibration and shaking of the equipment during operation, prolongs the service life of the equipment, and improves the reliability and stability of the equipment.

[0041] The size of the pressing plate 43 is larger than that of the support platform 2. In this way, when the telescopic motor 41 drives the pressing plate 43 to press down, the pressing plate 43 can completely cover the hooks 31 on the support platform 2, ensuring that all the hooks 31 are evenly and effectively pressed flat, avoiding the situation where some hooks 31 cannot be flattened or are not completely flattened due to the small size of the pressing plate 43, ensuring the integrity and consistency of the flattening of the hooks 31, and improving the quality and qualified rate of the product. At the same time, since all the hooks 31 can be effectively flattened at one time, the work efficiency is improved, and the processing time and cost are reduced.

[0042] The working principle of the present invention is as follows: first, the commutator body 3 is placed in the mounting hole 11 of the base 1, and the support platform 2 is threadedly connected to the inner wall of the mounting hole 11 through the bottom threaded column 21. The commutator body 3 is placed in the plug hole 22 of the support platform 2. The support platform 2 is rotated according to the length of the commutator body 3 to adjust its height to ensure that the hook 31 is in a suitable position. The friction pattern 23 on the outer peripheral wall of the support platform 2 facilitates this operation and improves efficiency. Next, the rotary motor 6 at the bottom of the workbench 7 drives the second bevel gear 61 to rotate, and the meshing first bevel gear 51 drives the screw 5 to rotate, so that the clamping ring 52 on the screw 5 moves in the slide groove 71 to clamp the outer peripheral wall of the commutator body 3. During this process, the limit ring 8 at the top of the avoidance opening 12 of the base 1 limits the height of the threaded column 21 to prevent it from hindering the movement of the clamping ring 52. Then, the telescopic motor 41 on the side wall horizontal plate 42 of the mounting frame 4 works, driving the pressing plate 43 to move up and down. The pressing plate 43 is larger than the support table 2 and can completely cover the hook 31, and accurately flatten it. The motor is used to accurately control the flattening force and stroke to avoid the influence of human factors and ensure product quality. Among them, the size of the socket 22 is larger than the outer periphery of the commutator body 3, which is convenient for installation, positioning and buffering. The base 1 is bolted to the workbench 7 to ensure stability. The positioning plate 9 at the bottom of the mounting frame 4 is bolted to the workbench 7 to ensure the accuracy of the sheet pressing mechanism. Finally, the flattening process of the commutator hook 31 is completed efficiently, improving production efficiency and product quality. The device can adapt to commutators of various specifications and has strong versatility.
