Detailed implementation manner
[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0020] The present invention provides a technical solution: As Figures 1 to 4 shown, in this embodiment, a positioning device for plastic part processing includes a processing table 1. Two symmetrically distributed movable blocks 3 are arranged on the upper surface of the processing table 1. The bottoms of the two movable blocks 3 are fixedly connected with sliders 5. The two sliders 5 are slidably installed in a sliding groove 2 opened on the upper surface of the processing table 1. A driving component acting on the two sliders 5 is arranged in the processing table 1. A positioning and fixing component is arranged on the movable block 3. The positioning and fixing component includes a fixed plate 7, a movable rod 8, a clamping roller 9, a spring 10, a telescopic rod 11 and a locking component acting on the movable rod 8. A plurality of through grooves 12 are opened on the movable block 3. The plurality of through grooves 12 are arranged side by side at equal intervals. Movable rods 8 are respectively slidably inserted in the plurality of through grooves 12. One end of the movable rod 8 is rotatably connected with a vertically arranged clamping roller 9. The other end of the movable rod 8 is internally slidably inserted with a telescopic rod 11. The other ends of the plurality of telescopic rods 11 are fixedly connected with a fixed plate 7. The fixed plate 7 is fixedly connected to the side wall of the movable block 3. A spring 10 is sleeved on the outer surface of the telescopic rod 11. The spring 10 is made of carbon steel. The two ends of the spring 10 are respectively fixedly connected to the end of the movable rod 8 and the side wall of the fixed plate 7. A locking component acting on the movable rod 8 is arranged on the movable block 3.
[0021] During use, place the plastic processing part on the processing table 1. Control the two sliders 5 to approach each other through the driving component, thereby controlling the two movable blocks 3 to approach each other. The clamping rollers 9 on the two movable blocks 3 will press against the processing part. The movable rod 8 is slidably inserted into the through groove 12 on the movable block 3. As the clamping roller 9 presses against the processing part, the movable rod 8 will contract into the through groove 12 and compress the spring 10. The acting force of the spring 10 restoring deformation will cause the clamping roller 9 to generate a clamping force on the processing part. At the same time, each movable rod 8 will contract different lengths according to the unevenness of different positions on the surface of the workpiece, so that the clamping rollers 9 are automatically arranged into the shape of the outer surface of the processing part. Then, lock the movable rod 8 through the locking component to prevent the movable rod 8 from moving. Finally, continue to use the driving component to control the two movable blocks 3 to approach each other, so that the clamping roller 9 tightly presses against the processing part, thereby completing the positioning and fixing of the processing part. This device can automatically adjust the shape of the clamping surface according to the different shapes of different processing parts, so that the clamping surface can always fit the outer surface of the processing part, and the applicable range is wider.
[0022] The locking component includes a clamping plate 14, a connecting plate 15, an adjusting lead screw 16 and a guiding column 18. Activity grooves 13 extending to the upper surface of the movable block 3 are respectively opened on the top walls of the inner cavities of multiple through grooves 12. Multiple clamping plates 14 are respectively slidably inserted into the multiple activity grooves 13. The multiple clamping plates 14 are fixedly connected to the bottom of the connecting plate 15. The bottom of the guiding column 18 slidably penetrates one end of the connecting plate 15 and is fixedly connected to the upper end of the movable block 3. The adjusting lead screw 16 penetrates the other end of the connecting plate 15 and is connected to the connecting plate 15 through a threaded fit. The bottom of the adjusting lead screw 16 is rotatably connected to the upper end of the movable block 3. The upper end of the adjusting lead screw 16 is fixedly connected with an adjusting member 17.
[0023] During use, rotate the adjusting member 17 to drive the adjusting lead screw 16 to rotate, control the connecting plate 15 to move downward, thereby controlling the multiple clamping plates 14 to move downward, so that the multiple clamping plates 14 are inserted into the activity grooves 13 and press against the upper ends of the movable rods 8, and the locking of the movable rods 8 can be completed.
[0024] Among them, the bottom of the clamping plate 14 is subjected to frosted treatment.
[0025] Such a setting can increase the friction between the clamping plate 14 and the movable rod 8.
[0026] Among them, the driving component includes a double-headed lead screw 6 and a motor 4. The two ends of the double-headed lead screw 6 respectively penetrate the two sliders 5 and are respectively connected to the two sliders 5 through a threaded fit. The two ends of the double-headed lead screw 6 are rotatably connected to the two inner walls of the sliding groove 2. The motor 4 is fixedly installed on the outer wall of the processing table 1. The output shaft of the motor 4 is fixedly connected to the end of the double-headed lead screw 6.
[0027] During use, start the motor 4 to drive the double-headed lead screw 6 to rotate, thereby controlling the two sliders 5 to approach each other, and further controlling the two movable blocks 3 to approach each other.
[0028] The utility model provides a positioning device for plastic part processing, and the specific working principle is as follows:
[0029] During use, place the plastic processing part on the processing table 1, and control the two sliders 5 to approach each other through the driving component, thereby controlling the two movable blocks 3 to approach each other. The clamping rollers 9 on the two movable blocks 3 will press on the processing part, and the movable rod 8 is slidably inserted into the through groove 12 on the movable block 3. As the clamping roller 9 presses on the processing part, the movable rod 8 will contract into the through groove 12 and compress the spring 10. The acting force of the spring 10 to restore deformation will cause the clamping roller 9 to generate a clamping force on the processing part. At the same time, each movable rod 8 will contract different lengths according to the unevenness of different positions on the surface of the workpiece, so that the clamping rollers 9 are automatically arranged into the shape of the outer surface of the processing part. Then, lock the movable rod 8 through the locking component to complete the positioning and fixing of the processing part. This device can automatically adjust the shape of the clamping surface according to the different shapes of different processing parts, so that the clamping surface can always fit the outer surface of the processing part, and the scope of application is wider.
[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
