[0020] The utility model provides a flexible positioning auxiliary device: including an adjustment base plate 1, a flexible positioning mechanism 2, a positioning piece 3 and a positioning auxiliary mechanism, the positioning auxiliary mechanism including a fixed block 4, multiple pin holes 5, multiple positioning pins 6, multiple limiting components 7, a protective component 8, multiple identification blocks 13, a stabilizing bar 14, a storage box 15 and a storage cover 16, the limiting component 7 including a limiting column 9 and a twisting head 10, the protective component 8 including a protective pad 11 and multiple protective layers 12, the above-mentioned solution solves the problem that the existing axial automated flexible auxiliary positioning device can only squeeze the workpiece for positioning, cannot constrain the position of the vertical plane of the workpiece, which will cause errors during processing and reduce product quality.

[0021] According to this specific embodiment, the adjustment base plate 1 is arranged on the workbench of the automation equipment, the flexible positioning mechanism 2 is arranged above the adjustment base plate 1, the positioning piece 3 is arranged on one side of the flexible positioning mechanism 2, the fixed block 4 is fixedly connected to one side of the positioning piece 3, a plurality of the latch openings 5 ​​are arranged on the fixed block 4, a plurality of the positioning pins 6 are respectively threaded into the plurality of the latch openings 5, each of the limiting components 7 is arranged at one end of each of the positioning pins 6, and the protective component 8 is arranged on the fixed block 4. When fixing the workpiece, according to needs, the plurality of limiting components 7 are installed in the corresponding plurality of latch openings 5 ​​through the plurality of positioning pins 6, and the flexible positioning mechanism 2 is started so that the positioning piece 3 drives the fixed block 4 to move toward the workpiece. When the fixed block 4 is about to press the workpiece, the flexible positioning mechanism 2 is paused, and the workpiece is placed in the desired position through the plurality of positioning pins 6 and the plurality of limiting components 7. The flexible positioning mechanism 2 is started again until the auxiliary component on the fixed block 4 is in close contact with the workpiece, and the positioning is completed.

[0022] Among them, the limiting column 9 is fixedly connected to one end of the positioning pin 6, and the twisting head 10 is fixedly connected to the end of the limiting column 9 away from the positioning pin 6. When installing the positioning pin 6, align the positioning pin 6 with the corresponding pin hole 5, twist the twisting head 10, and screw the positioning pin 6 into the pin hole 5 through the limiting column 9.

[0023] Secondly, the protective pad 11 is fixedly connected to the side of the fixed block 4 away from the positioning plate 3, each of the protective layers 12 is arranged on one side of each of the positioning pins 6, and each of the protective layers 12 is fixedly connected to the surface of each of the limiting columns 9. The protective pad 11 replaces the fixed block 4 to contact the workpiece, thereby preventing the fixed block 4 from wearing against the workpiece, and multiple protective layers 12 replace multiple limiting columns 9 to contact the workpiece, thereby preventing the limiting columns 9 from wearing against the workpiece.

[0024] At the same time, each of the identification blocks 13 is fixedly connected to the top of each of the pin holes 5, and the stabilizing bar 14 is fixedly connected to the top of the fixing block 4. When installing the positioning pin 6, it can be determined where it should be installed based on the contents on the multiple identification blocks 13. The stabilizing bar 14 can make the positional relationship between the fixing block 4 and the flexible positioning more stable, thereby improving the stability of the device.

[0025] Finally, the storage box 16 is arranged on one side of the adjustment base plate 1, and the storage cover 16 is hinged on the top of the storage box 15. When using the multiple positioning pins 6 and the multiple limiting components 7, open the storage cover 16 and take them out from the storage box 15 for use. When not in use, put the multiple positioning pins 6 and the multiple limiting components 7 into the storage box 15 and close the storage cover 16. This makes it easy to take and use the multiple positioning pins 6 and the multiple limiting components 7, and can also effectively prevent them from being lost.

[0026] When fixing the workpiece, according to needs, multiple limiting components 7 are installed in the corresponding multiple latch holes 5 through multiple positioning pins 6. During installation, the positioning pins 6 are aligned with the corresponding latch holes 5, and the twisting head 10 is twisted to screw the positioning pins 6 into the latch holes 5 through the limiting columns 9. The flexible positioning mechanism 2 is started to make the positioning piece 3 drive the fixing block 4 to move toward the workpiece. When the protective pad 11 on the fixing block 4 is about to press the workpiece, the flexible positioning mechanism 2 is paused, and the workpiece is moved to be close to the protective layer 12 on the multiple limiting columns 9 installed on the fixing block 4. The multiple positioning pins 6 and the multiple limiting components 7 are placed in the desired position, and the flexible positioning mechanism 2 is started again until the auxiliary component on the fixing block 4 is in close contact with the workpiece, and flexible positioning is completed. When using multiple positioning pins 6 and multiple limiting components 7, the storage cover 16 is opened and the workpiece is taken out from the storage box 15 for use. Yes, when not in use, the plurality of positioning pins 6 and the plurality of limiting components 7 can be placed in the storage box 15 and the storage cover 16 can be closed. This can facilitate the use of the plurality of positioning pins 6 and the plurality of limiting components 7 and effectively prevent them from being lost. When installing the positioning pins 6, the content on the plurality of identification blocks 13 can be used to determine where they should be installed. The stabilizing bar 14 can make the positional relationship between the fixed block 4 and the flexible positioning mechanism 2 more stable, thereby improving the stability of the device. The protective pad 11 replaces the fixed block 4 in contact with the workpiece to prevent the fixed block 4 from wearing against the workpiece. The plurality of protective layers 12 replace the plurality of limiting columns 9 in contact with the workpiece to prevent the limiting columns 9 from wearing against the workpiece. This avoids the problem that the existing axial automated flexible auxiliary positioning device can only squeeze the workpiece for positioning and cannot constrain the position of the vertical plane of the workpiece, which will cause errors during processing and reduce product quality. This achieves the effect of extending the service life of the device, improving positioning accuracy, and improving product quality.
