DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0018] Please refer to Figures 1-4, the present utility model provides a technical solution: a numerical control positioner, which includes a mounting plate 1. Both the upper and lower ends on the outside of the mounting plate 1 are provided with an inner support 2 and an outer support 3 through guide rails. The guide rails are existing linear guide rails, which have the characteristics of high precision, high rigidity and low friction, and can ensure the linear movement of the inner support 2 and the outer support 3 in the vertical direction, that is, the two groups of inner supports 2 and outer supports 3 can be closed or separated from each other. The top of the inner support 2 is fixed with a cylinder 4 that pushes the outer support 3 to move horizontally along the outer end of the inner support 2 through a support block. The output end of the cylinder 4 is fixedly connected to the inner end of the outer support 3 through a connecting block. And a rotary motor 5 is fixedly installed on the outside of the outer support 3 through a fixing bolt. A connecting frame 6 driven by the rotary motor 5 is installed inside the outer support 3. The output shaft of the rotary motor 5 is connected to the middle of the connecting frame 6. A multi-functional clamping plate 7 is detachably installed on the connecting frame 6. A plurality of assembly grooves are evenly arranged around the outside of the multi-functional clamping plate 7. A plurality of positioning clamping blocks 8 of different specifications are installed in the assembly grooves on the outside of the multi-functional clamping plate 7. In this structure, when positioning a workpiece, the cylinder 4 can push the outer support 3 to move horizontally along the outer end of the inner support 2, so that the relative distance between the inner support 2 and the outer support 3 can be adjusted to adapt to workpieces of different sizes. And the rotary motor 5 drives the connecting frame 6 to rotate. The multi-functional clamping plate 7 on the connecting frame 6 can select a suitable positioning clamping block 8 for clamping according to the shape and size of the workpiece. At the same time, the positioning clamping blocks 8 installed in the assembly grooves on the outside of the multi-functional clamping plate 7 can be quickly replaced according to the needs of the workpiece, reducing the inconvenience and cost caused by replacing the fixture. At the same time, the multi-functional clamping plate 7 is easy to disassemble and maintain from the connecting frame 6, reducing the difficulty and cost of regular calibration and maintenance, improving the adaptability and working efficiency of the numerical control positioner, and solving the problem that the existing numerical control positioner needs to frequently replace the fixture when facing workpieces of different materials and shapes, increasing the operation complexity and cost. One end of the outer support 3 connected to the inner support 2 is provided with a limiting shaft 12, and a limiting hole matching the structure of the limiting shaft 12 is arranged inside the inner support 2. In this structure, when the outer support 3 moves horizontally along the outer end of the inner support 2, the limiting shaft 12 will slide synchronously in the limiting hole inside the inner support 2, thereby restricting the moving range of the outer support 3 and ensuring the relative position relationship between the outer support 3 and the inner support 2. This not only ensures the stability of the outer support 3 during the movement process, but also makes the connection between the outer support 3 and the inner support 2 more firm and reliable, improving the positioning accuracy and stability of the numerical control positioner. Guide sleeves 9 are welded and fixed on both the front and rear sides of the outer end of the inner support 2. And a guide shaft 10 is horizontally inserted inside the guide sleeve 9. And the outer end of the guide shaft 10 is welded and fixed to the outer wall of the outer support 3. In this structure, when the outer support 3 moves horizontally along the outer end of the inner support 2, the guide shaft 10 will also horizontally insert and move inside the guide sleeve 9, further restricting the moving direction of the outer support 3 and making the stability of the outer support 3 during the movement process higher. Two groups of clamping blocks 11 are symmetrically arranged on the inner side of the multi-functional clamping plate 7.Moreover, the width between each group of clamping blocks 11 matches the width of the connecting frame 6. And a locking bolt is connected to the clamping block 11 through a threaded structure. There is a threaded hole on the connecting frame 6 that matches the locking bolt structure on the clamping block 11. In this structure, when it is necessary to replace the multifunctional clamping plate 7, only need to align the clamping block 11 with the connecting frame 6, and then fix the clamping block 11 and the connecting frame 6 together through the locking bolt. This not only simplifies the installation and disassembly process of the multifunctional clamping plate 7, but also makes the connection between the multifunctional clamping plate 7 and the connecting frame 6 firm and reliable, improving the adaptability and working efficiency of the numerical control positioner. A cross-shaped strip 13 is welded and fixed on the outer side of the connecting frame 6, and an embedding groove 14 that matches the structure of the strip 13 is provided on the inner side of the multifunctional clamping plate 7. In this structure, the embedding groove 14 of the multifunctional clamping plate 7 can be aligned with the strip 13 on the connecting frame 6 to effectively maintain the stability of the multifunctional clamping plate 7 after installation, making the connection between the multifunctional clamping plate 7 and the connecting frame 6 more firm and reliable. Socket seats 15 are fixedly installed on the outer parts of the inner ends of the positioning clamping blocks 8. And a number of convex columns 16 are arranged around in the assembly groove on the outer side of the multifunctional clamping plate 7. And a number of clamping sleeves 17 that match the structure of the convex columns 16 are arranged around the outer edge of the socket seat 15. In this structure, when it is necessary to install the positioning clamping block 8, only need to align the clamping sleeves 17 on the outer edge of the socket seat 15 with the convex columns 16 in the assembly groove on the outer side of the multifunctional clamping plate 7, and then slide the positioning clamping block 8 along the direction of the convex columns 16, then the quick installation of the positioning clamping block 8 can be realized. And the outside of the connection between the convex columns 16 and the clamping sleeves 17 can also be fixed by screwing in nuts, further improving the connection firmness between the positioning clamping block 8 and the multifunctional clamping plate 7.,
[0019] Working principle: When using this numerical control positioner, first, the two groups of inner supports 2 and outer supports 3 can be adjusted to an appropriate distance on the mounting plate 1 through the guide rails. Then, the outer support 3 is pushed by the cylinder 4 to horizontally displace along the outer end of the inner support 2, so that the relative distance between the inner support 2 and the outer support 3 is adjusted. When the outer support 3 horizontally displaces, it will drive the limit shaft 12 to slide in the limit hole inside the support 2, and the guide shaft 10 horizontally penetrates and moves inside the guide sleeve 9 until the outer support 3 is adjusted to an appropriate position. Then, the rotating motor 5 is driven to rotate the connecting frame 6. The multifunctional clamping plate 7 on the connecting frame 6 can select an appropriate positioning clamping block 8 for clamping according to the shape and size of the workpiece. When it is necessary to disassemble the multifunctional clamping plate 7 from the connecting frame 6, first loosen the locking bolt on the clamping block 11, and then make the strip 13 disengage from the embedding groove 14, then the multifunctional clamping plate 7 can be quickly disassembled. When it is necessary to replace a single positioning clamping block 8, the positioning clamping block 8 slides out from the outside of the convex columns 16 through the clamping sleeves 17 on the outer edge of the socket seat 15, then the disassembly of the positioning clamping block 8 can be quickly completed. Then reinstall the positioning clamping block 8 and screw in nuts on the outside of the connection between the convex columns 16 and the clamping sleeves 17 for fixation, thus completing a series of work.
[0020] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
