3results about How to "Solve the machining accuracy" patented technology

This application relates to the field of fixture technology, and discloses a positioning device and a fixture positioning system. The positioning device provided in this application includes a base assembly, a drive mechanism, an identification unit, and at least two positioning members. The base assembly has a mounting portion, and each positioning member is movably mounted on the base assembly. The drive mechanism includes a rotating member and a drive assembly. The rotating member and at least part of the drive assembly are mounted on the base assembly. The rotating member is driveably connected to each positioning member, and the drive assembly is driveably connected to the rotating member. The drive assembly moves relative to the base assembly, causing the rotating member to rotate, thereby driving each positioning member to move towards the center of the mounting portion. Each positioning member abuts against a positioning body, pushing the positioning body to the center of the mounting portion. The identification unit performs image recognition on the orientation of the positioning body relative to the center. According to the positioning device provided in this application, precise adjustment of the orientation of the assembly can be achieved, thereby ensuring the processing or assembly accuracy of the product.

The utility model provides a kind of double RGV logistics trolley and its butt joint structure, belong to machining technical field, wherein double RGV logistics trolley includes the trolley support that can cooperate with logistics bed body guide rail, trolley support is provided with two, the side of each trolley support is fixed with oil cylinder connecting plate, fixed with positioning oil cylinder on oil cylinder connecting plate, the piston rod of positioning oil cylinder is towards downwards and penetrates oil cylinder connecting plate;Correspondingly, the side of logistics bed body guide rail is equipped with fixed block, fixed block is equipped with shaft sleeve inside, when piston rod extends, the lower end of piston rod can be inserted into shaft sleeve;The bottom of each trolley support is also installed with motor, the output of motor is fixed with gear, gear can be engaged with rack of logistics bed body guide rail side portion.The utility model solves the problem that the part on conveying tooling plate is prone to deviation in position when being clamped by tooling due to inaccurate positioning of double RGV trolley in the prior art, which is conducive to improving the machining precision of subsequent machining units for parts.
