DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-3 A rotating assembly for automobile parts inspection shown in the figure includes a column 101 and a positioning mechanism. A mechanical arm 102 is sleeved on the outer wall of the column 101. A driving mechanism is provided at the bottom end of the column 101. A mounting seat is provided on the mechanical arm 102. The mounting seat is used to install a clamp. The clamp clamps the automobile parts, and then the column 101 is driven to rotate by the driving mechanism. The clamped automobile parts can be made to revolve under the connection with the mechanical arm 102, thereby realizing multi-station inspection of automobile parts.

[0022] In a preferred embodiment, the positioning mechanism is used to fix the robot arm 102 and the column 101, and the positioning mechanism includes a connecting ring 201 sleeved on the outer wall of the column 101, and the inner wall of the connecting ring 201 is provided with a plurality of movable grooves 202, and the interiors of the plurality of movable grooves 202 are movably provided with extrusion sheets 203, the connecting ring 201 is fixedly connected to the bottom end of the robot arm 102, and the interior of the connecting ring 201 is provided with a synchronization mechanism, and the synchronization mechanism is provided with an annular groove 301 at the bottom end of the connecting ring 201, and the inner wall of the annular groove 301 is interspersed with an extrusion ring 302, and the inner wall of the extrusion ring 302 is provided with a frustum 303, and a movable hole 304 is provided between the movable groove 202 and the annular groove 301, and the inner wall of the movable hole 304 is movably interspersed with a connecting rod 305, and the connecting rod 305 One end is fixedly connected to one side of the extrusion sheet 203, and the other end of the connecting rod 305 is set in a hemispherical shape, which can be moved upward in the annular groove 301 through the extrusion ring 302, so that the frustum 303 squeezes the connecting rod 305, and the connecting rod 305 drives the extrusion sheet 203 to move, so that multiple extrusion sheets 203 can move simultaneously in the movable groove 202, until multiple extrusion sheets 203 are pressed against the outer wall of the column 101 together, so that the connecting ring 201 and the column 101 are in a concentric state, that is, the robot arm 102 and the column 101 are in a concentric state, thereby improving the working stability of the rotating assembly, and through the setting of the frustum 303, the connecting rods 305 located at the same horizontal height can maintain the same state, thereby improving the working stability of the synchronization mechanism.

[0023] Among them, the outer wall of the extrusion ring 302 is provided with an external thread groove 401, and the inner wall of the annular groove 301 is provided with an internal thread groove 402. The outer wall of the internal thread groove 402 is meshed and connected with the outer wall of the external thread groove 401. Through the cooperation between the external thread groove 401 and the internal thread groove 402, the extrusion ring 302 can rotate in the annular groove 301 to perform lifting and lowering movements.

[0024] Among them, a threaded hole 501 is opened on the outer wall of the connecting ring 201, and the interior of the threaded hole 501 is connected with the interior of the annular groove 301.

When the extrusion ring 302 rotates and rises in the annular groove 301 until multiple extrusion sheets 203 all press against the outer wall of the column 101, the extrusion ring 302 also rises to the maximum height. Then, the locking bolt 502 is screwed in the threaded hole 501 so that multiple locking bolts 502 all press against the outer wall of the extrusion ring 302, so that the extrusion ring 302 can be positioned in the annular groove 301, so that the extrusion ring 302 will not automatically rise and fall, thereby improving the stability of the positioning mechanism and ensuring the stable operation of the rotating component.

[0025] Among them, an active cavity 601 is opened on the inner wall of the active hole 304, and a fixed ring 602 is slidably connected to the inner wall of the active cavity 601.
