[0002] Circular piston thin-wall parts usually refer to cylindrical or conical thin-wall parts used in mechanical equipment such as piston engines, compressors, and hydraulic cylinders. When detecting circular piston thin-wall parts, positioning tooling is usually used to ensure the stability of the workpiece during the detection process.

[0003] However, some existing positioning tooling for detecting circular piston thin-wall parts usually uses a six-jaw inner support and a single-piece inner support inner hole method. However, this method is easy to deform the circular thin-wall parts and cause unstable dimensions and low single-piece measurement efficiency. Moreover, when detecting circular piston thin-wall parts, it is necessary to adjust the six-jaw inner support according to the inner diameter of the workpiece, which cannot achieve rapid positioning, has low practicability and low positioning efficiency, and affects the subsequent detection efficiency of the staff for circular piston thin-wall parts. In view of this, we propose a multi-piece detection coordinate tooling for rapid and accurate positioning to solve the above problems. Summary of the Utility Model

The number of mounting screw holes 11 matches the number of positioning columns 3. The internal threads of the mounting screw holes 11 are connected with mounting screws 10. The bottom of the positioning column 3 also has mounting screw holes 11. The mounting screws 10 match the mounting screw holes 11 provided inside the positioning column 3. A first adjusting groove 12 is provided on the upper surface of the fixed base plate 1. An adjusting component is provided inside the first adjusting groove 12.

Subsequently, the staff places the circular piston thin-walled part to be processed inside the placement cavity 4. At this time, the inner hole of the circular piston thin-walled part will contact and squeeze the inclined surface on the upper part of the lateral positioning column 5. At this time, the lateral positioning column 5 will drive the guide block 7 to slide inside the guide groove 6, and the spring 9 will contract until the bottom of the circular piston thin-walled part contacts the bottom wall of the placement cavity 4. At this time, the elastic force of the spring 9 itself will The three lateral positioning columns 5 are used to position the circular piston thin-walled parts, and finally the circular piston thin-walled parts are quickly and accurately positioned.

The movement of the mounting plate 13 drives the movement of the electric push rod 14. The movement of the electric push rod 14 drives the movement of the connecting plate 15. The movement of the connecting plate 15 drives the movement of the second adjustment block 18 inside. Finally, the moving bottom plate 2 drives the positioning column 3 and the workpiece to move in the front-back direction. When the staff needs to adjust the position of the workpiece in the left-right direction, by rotating the second threaded rod 17, the rotation of the second threaded rod 17 drives the second adjustment block 18 to slide inside the second adjustment groove 16. Finally, the movement of the second adjustment block 18 drives the moving bottom plate 2 to move in the left-right direction. When the staff needs to adjust the height of the workpiece, by starting the electric push rod 14, the movement of structures such as the connecting plate 15 can be driven. Through the above structure, the flexibility of the device is further improved, facilitating the staff to adjust the position of the workpiece according to the actual work requirements, facilitating the detection of multiple workpieces, and further improving the work efficiency of the staff.

[0030] Working principle:

[0031] When the multi-piece detection coordinate tooling for rapid and precise positioning is in use, the positioning posts 3 are placed on the upper part of the moving base plate 2 by the staff. Subsequently, the mounting screws 10 are respectively threadedly connected to the mounting screw holes 11 inside the moving base plate 2 and the positioning posts 3, thereby realizing the installation of multiple positioning posts 3. Then, the circular piston thin-walled parts to be processed are placed inside the placement cavity 4 by the staff. At this time, the inner hole of the circular piston thin-walled part will contact and press against the inclined surface on the upper part of the lateral positioning post 5. At this time, the lateral positioning post 5 will drive the guide block 7 to slide inside the guide groove 6, and the spring 9 will contract until the bottom of the circular piston thin-walled part contacts the bottom wall of the placement cavity 4. At this time, relying on the elastic force of the spring 9 itself, the three lateral positioning posts 5 will position the circular piston thin-walled part, and finally realize the rapid and precise positioning of the circular piston thin-walled part.
