Description

Technical Field

[0001] This utility model relates to the field of plastic rod processing technology, specifically a CNC tooling for processing plastic rods. Background Technology

[0002] In the plastics processing industry, CNC tooling is the core equipment for achieving efficient and precise processing of plastic rods, especially suitable for scenarios requiring continuous production and adaptability to multiple specifications. Through the design of specialized tooling, the stability of rod feeding, processing accuracy, and equipment versatility can be improved, meeting the dual needs of mass production and customized processing. Therefore, it is necessary to develop CNC tooling for plastic rod processing that is more adaptable and easier to operate.

[0003] Existing CNC tooling for processing plastic rods often suffers from insufficient adaptability to multiple specifications and inadequate continuous feeding capabilities. Specifically, traditional tooling lacks an adjustable positioning chuck and feeding component design, resulting in frequent mold changes or equipment adjustments when processing rods of different diameters or lengths, leading to long mold change times and low efficiency. During feeding, the lack of coordinated rotational thrust from the tilting drive wheel and rotating roller easily causes unstable rod feeding, wobbling, or even deviation, affecting processing accuracy. The positioning chuck height is inconvenient to adjust and cannot adapt to the clamping requirements of rods of different diameters, resulting in unstable rod fixation during processing and increasing the defect rate. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a CNC tooling for processing plastic rods to solve the technical problems of insufficient multi-specification adaptation and continuous feeding capacity in the prior art.

Detailed Implementation

[0010] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0011] The embodiments of this utility model will be described below based on its overall structure.

[0012] Example 1 Please see Figures 1-5This utility model provides a technical solution: a CNC tooling for processing plastic rods, including a base plate 1, a worktable 2 on the base plate 1, a movable frame 3 movably mounted on the worktable 2, a processing device 31 for processing plastic rods mounted on the movable frame 3, a height-adjustable positioning chuck 21 on the worktable 2, and a rod feeding assembly 4 on the base plate 1; through modular design, processing, positioning, and feeding functions are integrated, improving the overall coordination and ease of operation of the equipment; The bar feeding assembly 4 includes a lifting column 42 mounted on a base plate 1. A platform 43 is mounted on the top of the lifting column 42. A rotating roller 45 is mounted on the platform 43. A movable plate 46 is slidably mounted on the platform 43. Multiple second mounting frames 461 are mounted on the movable plate 46. A transmission wheel 462 is rotatably mounted in each second mounting frame 461. The second mounting frames 461 are inclined. Through the rotational cooperation between the inclined transmission wheel 462 and the rotating roller 45, the rotational transmission of the plastic bar is realized, reducing frictional resistance during the transmission process and improving the smoothness of feeding. When the rotating roller 45 rotates, the plastic rod is conveyed to the worktable 2 in a rotating manner under the action of the inclined transmission wheel 462. The rotating conveying method makes the rod evenly stressed, avoids deformation or scratches caused by local stress concentration, and ensures the quality of the processed surface. Furthermore, an adjustment groove 41 is provided on the base plate 1, and the lifting column 42 is slidably disposed in the adjustment groove 41 to adjust the position of the plastic rod; by sliding the lifting column 42 in the adjustment groove 41, it can be adapted to the positioning chuck 21 at different height positions to ensure that the feeding path is accurately aligned with the processing position and improve the positioning accuracy. Furthermore, the bar feeding assembly 4 includes a telescopic rod 463 mounted on the table 43, with the output end of the telescopic rod 463 fixedly connected to the outside of the movable plate 46. When the telescopic rod 463 is in an extended or retracted state, the movable plate 46 moves closer to or further away from the rotating roller 45 on the table 43 to meet the feeding needs of plastic sheets of different sizes and specifications. By adjusting the position of the movable plate 46 through the telescopic rod 463, the distance between the transmission wheel 462 and the rotating roller 45 can be dynamically adjusted to adapt to bars of different diameters and improve the versatility of the equipment. Furthermore, a first mounting frame 44 is provided on the table 43, and the rotating roller 45 is rotatably mounted in the first mounting frame 44; a mounting base 451 is provided on the table 43, and a drive motor 452 is embedded in the mounting base 451. Both the output shaft of the drive motor 452 and the outside of the rotating roller 45 are provided with pulleys 453, and a belt 454 is connected to the two pulleys 453 for transmission; through the transmission structure of the pulleys 453 and the belt 454, the drive motor 452 can stably drive the rotating roller 45, ensuring the consistency of the conveying speed and improving the processing efficiency.

[0013] Example 2 Please see Figures 3-6 Furthermore, in conjunction with Embodiment 1, the movable frame 3 is provided with an auxiliary support assembly 32 for supporting the plastic rod. The auxiliary support assembly 32 includes an L-shaped rod 321 disposed on the movable frame 3. Two L-shaped rods 321 are provided, and the two L-shaped rods 321 are symmetrically disposed on the movable frame 3. A height-adjustable support seat 322 is disposed in the two L-shaped rods 321, and a soft pad 323 is disposed in the support seat 322. Through the symmetrical arrangement of the L-shaped rods 321 and the height adjustment function of the support seat 322, stable support for the bottom of the rod is achieved, the shaking caused by gravity is counteracted, and the processing accuracy is improved. When the movable frame 3 moves on the workbench 2, the L-shaped rod 321 is in a sliding state, the position of the support seat 322 is in a changing state, and the soft pad 323 on the support seat 322 contacts the bottom end of the plastic rod to support the plastic rod; through the flexible contact design of the soft pad 323, scratches or damage to the surface of the rod caused by hard contact are avoided, ensuring the surface quality of the finished product. Furthermore, at least two positioning chucks 21 are provided, both movably mounted on the worktable 2. Each positioning chuck 21 has a movable seat 51 at its bottom, which slides on the worktable 2. Multiple pads 52 are provided on the movable seat 51. Both the movable seat 51 and the pads 52 have insertion slots 521. The bottom of each pad 52 has a magnetic insertion post 522 that can be inserted into the insertion slot 521. The bottom of the insertion slot 521 has a magnetic insertion post 522 that can be inserted into the magnetic insertion post. The bottom end of the connecting post 522 has a magnet with opposite magnetic properties; when multiple pads 52 are inserted and installed, the height of the positioning chuck 21 changes; through the magnetic cooperation between the magnetic connecting post 522 and the insertion slot 521, the pads 52 can be quickly inserted and installed, improving the convenience of adjusting the height of the positioning chuck 21 and adapting to the clamping requirements of bars of different diameters; through the stacking and insertion of the pads 52, the height of the positioning chuck 21 can be precisely adjusted, ensuring the stability of bar clamping and avoiding displacement or vibration during processing; Furthermore, the bottom of the support base 322 is also provided with a movable seat 51 and a pad 52 to adjust the height of the support base 322; through the combination structure of the movable seat 51 and the pad 52, the height of the support base 322 can be flexibly adjusted, ensuring that the soft pad 323 always maintains the best contact state with the bottom of the bar, thereby improving the support stability and processing accuracy.

[0014] The workflow for machining CNC fixtures from plastic rods is as follows: Before processing begins, the height of the table 43 is adjusted by sliding the lifting column 42 in the adjusting groove 41 to align the rotating roller 45 with the positioning chuck 21. The telescopic rod 463 pushes the movable plate 46 to slide on the table 43, adjusting the distance between the transmission wheel 462 and the rotating roller 45 to accommodate plastic rods of different diameters. One end of the rod is placed between the positioning chucks 21 and clamped, while the other end is attached to the rotating roller 45. The drive motor 452 drives the rotating roller 45 to rotate through the pulley 453 and belt 454. The inclined transmission wheel 462 generates a forward thrust as the rotating roller 45 rotates, causing the rod to be rotated and transferred to the positioning chuck 21 for fixing, thus completing the initial feeding and positioning. During processing, the movable frame 3 moves the processing equipment 31, and the L-shaped rod 321 of the auxiliary support component 32 slides with the movable frame 3. The support base 322 adjusts its height through the magnetic insertion structure between the movable base 51 and the pad 52. The soft pad 323 always fits against the bottom of the bar to counteract the shaking caused by gravity and ensure the accurate processing of the bar by the processing equipment 31. The positioning chuck 21 adjusts its spacing through the sliding of the movable base 51 to adapt to the clamping requirements of bars of different lengths. After one section of processing is completed, the positioning chuck 21 releases the rod, and the telescopic rod 463 pushes the movable plate 46 again, adjusting the distance between the transmission wheel 462 and the rotating roller 45. The rotating roller 45 rotates again, and the unprocessed part is pushed under the processing equipment 31 by the rotational thrust of the inclined transmission wheel 462. The support seat 322 of the auxiliary support component 32 moves with the movable frame 3, always maintaining stable support for the rod until the entire processing process is completed. The entire process is transmitted through the coordinated transmission of the rotating roller 45 and the inclined transmission wheel 462 of the rod feeding component 4, combined with the distance adjustment function of the telescopic rod 463, to achieve continuous and stable feeding and precise processing of plastic rods of different sizes, thereby improving processing efficiency and quality.
