[0001] The utility model relates to the technical field of brackets, in particular to a scanning and positioning bracket. Background Art

[0002] In the process of production and manufacturing, part cracking is a common quality problem; cracking may lead to the failure of part functions, damage or safety hazards. Therefore, after the parts are produced, a scanner is needed to scan and detect the parts to check whether there is any cracking condition, so as to monitor their quality; currently, most of the scanning brackets are fixed to the corresponding positions on the scanner through quick positioning holes, and then the product is placed on several support blocks adapted to the shape of the product on the scanning bracket for supporting and fixing the product. Then, the scanning bracket and the product are sent into the scanner for scanning and analysis and detection of internal impurities and cracking of the product, so as to detect whether the quality of the workpiece is qualified.

A number of tooth grooves meshing with the gear 15 are opened at the top wall of the slide rail 11. One end of the rotating shaft 14 is sleeved with a fixing block 16 outside the upper plate 10. A chamber 24 is opened inside the fixing block 16. A baffle 17 is arranged in the chamber 24, and the baffle 17 is fixedly connected with one end of the rotating shaft 14. A spring 18 is sleeved on the outer side of the rotating shaft 14 on the side of the baffle 17 close to the upper plate 10. One end of the fixing block 16 is rotatably connected with a rotating handle 19. Limiting rods 20 are symmetrically arranged on the outer wall of the fixing block 16.

The baffle 17 has a hexagonal structure, and the chamber 24 is adapted to the baffle 17 to limit the fixed block 16 so that it rotates synchronously with the rotating shaft 14. In this example, the first support block 3, the second support block 4, the third support block 5 and the fourth support block 6 are all L-shaped and are all made of PA6 + 30% glass fiber nylon material. A support inclined surface adapted to the workpiece body 2 is provided on one side of the vertical part of the fourth support block 6. Limiting grooves adapted to the workpiece body 2 are provided on one side of the vertical parts of the first support block 3, the second support block 4 and the third support block 5 to better penetrate the product for detection.

[0023] The working principle of the present utility model: When in use, it is fixed on the scanner by using the positioning block 7, and then the workpiece body 2 is placed on the first support block 3, the second support block 4, the third support block 5 and the fourth support block 6, and the corresponding ends of the workpiece body 2 adapted to them are respectively corresponding to the first support block 3, the second support block 4, the third support block 5 and the fourth support block 6, so as to support, position and fix the workpiece body 2, and then it is sent into the scanner for scanning and detection. Before placing the workpiece body 2, the positions of the first support block 3, the second support block 4, the third support block 5 and the fourth support block 6 can be finely adjusted according to actual needs. By twisting the twist handle to drive the screw rod 12 to rotate, and then driving the slider 13 to move back and forth, so that the slider 13 drives the slide rail 11 and then drives the upper plate 10 to move synchronously. When the left and right positions of the upper plate 10 need to be adjusted, the turning handle 19 can be pulled to drive the fixed block 16, and then cooperate with the baffle 17 to squeeze the spring 18. At the same time, the fixed block 16 will drive the connected limit rod 20 to move out of the jack, and then the upper plate 10 can be dragged to slide left and right along the slide rail 11. When the upper plate 10 moves, it drives the rotating shaft 14 and the gear 15. The gear 15 rotates under the action of a number of tooth grooves on the slide rail 11, so that the gear 15 drives the baffle 17 and then drives the fixed block 16 to rotate synchronously. Until the upper plate 10 is moved to the appropriate position, the pulling force on the turning handle 19 can be released, so that the fixed block 16 moves back under the elastic force of the spring 18, and then drives the limit rod 20 to reset and insert into the corresponding jack, realizing the restriction and fixation of the fixed block 16, thus completing the fixation of the gear 15, and then the position of the upper plate 10 can be restricted and fixed. And this method is also convenient for disassembling and assembling the upper plate 10, easy to use and more practical.
