Description
Technical Field
[0001] The utility model relates to the technical field of numerical control bulging machines, in particular to a clamping mechanism of a coil numerical control bulging machine. Background Art
[0002] The development of the clamping mechanism of the coil numerical control bulging machine is an inevitable result of the progress of industrial automation and precision manufacturing technology. It plays an important role in improving production efficiency, ensuring product quality, and reducing labor costs. With the continuous progress of technology, the application range of the clamping mechanism of the coil numerical control bulging machine will become wider and wider, and its functions and performance will also be continuously improved and enhanced.
[0003] In the prior art, traditional numerical control bulging equipment is designed for coils of specific sizes. This design limits the versatility and flexibility of the equipment, resulting in the need to replace or adjust the clamping mechanism when producing products of different specifications, increasing the production preparation time and cost. Frequent replacement or adjustment of the clamping mechanism not only increases the complexity of operation but also increases the cost of maintenance and replacement of components, which is not conducive to cost control. During multiple adjustment processes, the clamping mechanism may be worn or inaccurately positioned, affecting the machining accuracy and thus the product quality. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the defects existing in the prior art, and a clamping mechanism of a coil numerical control bulging machine is proposed.
[0005] To achieve the above object, the present utility model adopts the following technical solution: A clamping mechanism for a coil numerical control bulging machine, comprising a turntable. The spindle is rotatably connected inside the turntable. A chute is provided on the surface of the turntable. A telescopic arm is slidably connected to the circumferential surface of the turntable. A coupling is rotatably connected to the surface of the telescopic arm. An air pump is fixed to the front end face of the coupling. A slider is slidably connected inside the turntable. A support column is rotatably connected to the surface of the slider. A sliding frame is fixed to the upper end of the spindle. A limiting block is slidably connected to the inner wall of the sliding frame. The limiting block is rotatably connected to the support column. A device housing is fixed to the upper end face of the limiting block. In the prior art, traditional numerical control bulging equipment is designed for coils of specific sizes. This design limits the versatility and flexibility of the equipment, resulting in the need to replace or adjust the clamping mechanism when producing products of different specifications, increasing the production preparation time and cost. Frequent replacement or adjustment of the clamping mechanism not only increases the complexity of operation but also increases the cost of maintenance and replacement of components, which is not conducive to cost control. During multiple adjustment processes, the clamping mechanism may be worn or inaccurately positioned, affecting the processing accuracy and thus the product quality. To address such problems, the present utility model adopts an expansion tooth device. When a worker uses this clamping mechanism, after installing the spindle on the numerical control bulging machine, the worker also sleeves the coil on the surface of the device housing. At the same time, according to the coil diameter, the air pump is started to push the coupling forward, and the telescopic arm expands and rotates, thereby driving the disc to rotate. The slider drives the limiting block to expand along the arc groove. When the device housing expands until it supports the coil, the worker can turn off the air pump, thus achieving an increase in the versatility and flexibility of this clamping mechanism, adapting to coils of different diameters, and expanding the application range of the numerical control bulging machine.
[0006] Preferably, a pushing block is slidably connected to the inner wall of the device housing. A threaded rod is rotatably connected to the side end face of the pushing block. The threaded rod is threadedly connected to the device housing. A rotating knob is fixed to the side end face of the threaded rod. A sliding rod is slidably connected inside the device housing. A support frame is fixed to the side end face of the pushing block. A tooth is fixed to the upper end face of the sliding rod. In the prior art, traditional clamping mechanisms are often designed for coils of specific heights and lack the ability to adapt to coils of different heights, which limits their application in diversified production. When it is necessary to change the coil height, the traditional clamping mechanism may require complex adjustments or component replacements, which is not only time-consuming but also error-prone. Due to the cumbersome adjustment process, production may be interrupted or slowed down, affecting the overall production efficiency and the continuity of the process. To address such problems, the present utility model adopts an installation of telescopic teeth. The worker rotates the rotating knob to push the threaded rod forward inside the device housing towards the front end, causing the pushing block to lift the sliding rod upward with the help of the support frame, thereby enabling the clamping mechanism to better adapt to changing production requirements, reducing production interruptions, lowering labor costs, improving production efficiency and product quality, and meeting the requirements of modern manufacturing for high-efficiency and high-precision production.
[0007] Preferably, I-shaped sliding keys are fixed at both ends of the limit block. The I-shaped sliding keys usually have a large contact area and can bear a high load, thereby making the sliding process of the limit block more stable and steady.
[0008] Preferably, a rubber ring is sleeved on the surface of the rotary knob, thereby further improving the user's operation experience, making the operation smoother, and thus enhancing the user's hand feeling.
[0009] Preferably, a sector-shaped platform is provided at the upper end of the engaging teeth. The design of the sector-shaped platform helps to reduce the pushing force, makes the operation of pushing the coil into the device housing more convenient, reduces the operation difficulty and labor intensity.
[0010] Preferably, an arc surface is formed on the front end face of the pushing block to reduce the resistance during the pushing process, thereby enhancing the user's hand feeling.
[0011] Beneficial effects
[0012] 1. In the prior art, traditional numerical control bulging equipment is designed for coils of specific sizes. This design limits the versatility and flexibility of the equipment, resulting in the need to replace or adjust the clamping mechanism when producing products of different specifications, increasing the production preparation time and cost. Frequent replacement or adjustment of the clamping mechanism not only increases the complexity of the operation but also increases the cost of maintenance and replacement of components, which is not conducive to cost control. During multiple adjustments, the clamping mechanism may be worn or inaccurately positioned, affecting the processing accuracy and thus the product quality. In view of such problems, the present utility model adopts an expanding engaging tooth device. When a staff member uses this clamping mechanism, after installing the main shaft on the numerical control bulging machine, the staff member sleeves the coil on the surface of the device housing. At the same time, according to the coil diameter, the air pump is started to push the coupling forward, and at the same time, the telescopic arm expands and rotates, thereby driving the disc to rotate. The slider drives the limit block to expand along the arc groove. When the device housing expands until it supports the coil, the staff member can turn off the air pump, thereby increasing the versatility and flexibility of this clamping mechanism, adapting to coils of different diameters, and expanding the applicable range of the numerical control bulging machine.
[0013] 2. In the prior art, traditional clamping mechanisms are often designed for coils of specific heights and lack the ability to adapt to coils of different heights, which limits their application in diversified production. When it is necessary to change the coil height, the traditional clamping mechanism may require complex adjustments or component replacements, which are not only time-consuming but also error-prone. Due to the cumbersome adjustment process, production interruptions or slowdowns may occur, affecting the overall production efficiency and the continuity of the process. To address such problems, in the present utility model, by adopting a telescopic clamping tooth, when a worker rotates the rotating knob, the threaded rod is pushed forward along the inside of the device housing, and the pushing block uses the support frame to lift the sliding rod upward, so that the clamping mechanism can better adapt to changing production requirements, reduce production interruptions, lower labor costs, improve production efficiency and product quality, and meet the requirements of modern manufacturing for high-efficiency and high-precision production.

At the upper end of the main shaft 106, a sliding frame 107 is fixed. Inside the inner wall of the sliding frame 107, a limiting block 108 is slidably connected. The limiting block 108 is rotatably connected to the support column 105. On the upper end face of the limiting block 108, a device housing 109 is fixed. In the prior art, traditional numerically controlled bulging equipment is designed for coils of specific sizes. This design limits the versatility and flexibility of the equipment, resulting in the need to replace or adjust the clamping mechanism when producing products of different specifications, increasing the production preparation time and cost. Frequent replacement or adjustment of the clamping mechanism not only increases the complexity of operation but also increases the cost of maintenance and replacement of components, which is not conducive to cost control. During multiple adjustment processes, the clamping mechanism may be worn or inaccurately positioned, affecting the machining accuracy and thus the product quality. To address such problems, the present utility model adopts an expansion tooth 2041 device. When a worker uses this clamping mechanism, after installing the main shaft 106 on the numerically controlled bulging machine, the worker also puts the coil on the surface of the device housing 109. At the same time, according to the coil diameter, the air pump 103 is started to push the coupling 102 forward, and at the same time, the telescopic arm expands and rotates, thereby driving the disc to rotate. The slider 104 drives the limiting block 108 to expand along the arc groove. When the device housing 109 expands until it supports the coil, the worker can turn off the air pump 103, thereby increasing the versatility and flexibility of this clamping mechanism, adapting to coils of different diameters, and expanding the applicable range of the numerically controlled bulging machine.
[0024] Inside the inner wall of the device housing 109, a pushing block 2 is slidably connected. On the side end face of the pushing block 2, a threaded rod 201 is rotatably connected. The threaded rod 201 is threadedly connected to the device housing 109. On the side end face of the threaded rod 201, a rotating knob 202 is fixed. Inside the device housing 109, a sliding rod 204 is slidably connected. On the side end face of the pushing block 2, a support frame 203 is fixed. On the upper end face of the sliding rod 204, a tooth 2041 is fixed. At both ends of the limiting block 108, I-shaped sliding keys are fixed. A rubber ring is sleeved on the surface of the rotating knob 202. On the upper end of the tooth 2041, a sector platform is provided. On the front end face of the pushing block 2, an arc surface is provided.
[0025] Working principle of the present utility model: When using this clamping mechanism, after installing the main shaft 106 on the numerical control bulging machine, the staff member puts the coil on the surface of the device housing 109. At the same time, according to the diameter of the coil, the air pump 103 is started to push the coupling 102 forward. Meanwhile, the telescopic arm expands and rotates, driving the disc to rotate. The slider 104 drives the limiting block 108 to expand along the arc groove. When the device housing 109 expands until it props up the coil, the staff member can turn off the air pump 103 to fix the coil.
