A baffle (29) is fixedly connected to the inner wall of the base (1), and a limit rod (30) is fixedly connected to the surface of the baffle (29). At the same time, a vision detection assembly (28) is slidably connected to the limit rod (30). The vision detection assembly (28) is slidably disposed on the upper end of the base (1), and one end of a sliding rod (27) is rotatably connected to the surface of the vision detection assembly (28), and the other end of the sliding rod (27) is rotatably connected to the cylinder (26).

10. An automatic water meter gear assembly machine according to claim 1, characterized in that, The assembly method for the automatic water meter gear assembly machine was also disclosed, and the specific method is as follows: S1: The five-axis linkage execution component (2) accurately grabs the watch case, and the annular turntable indexing component (3) rotates the fixture at a preset angle to send it to the material picking station, while the fixture fixes the surface parts. S2: After starting the equipment, the monitoring component (5) inspects the parts to confirm that the deviation of the watch case placement position is ≤ ±0.01mm, and ensures that the gear shaft is precisely aligned with the watch case mounting hole and the gear with the shaft key. S3: The qualified parts group is transferred to the oil cotton applicator (6) station along with the annular turntable indexing component (3) to apply lubricating oil evenly to the gear meshing parts to ensure smooth operation and precise and controllable application amount; S4: After the coating is completed, the gears pass through the cleaning unit to remove the debris and residual oil on the surface, so as to avoid gear meshing jamming or assembly accuracy deviation caused by impurities. S5: The vision inspection component (28) acquires images of the gear through a camera on the surface, and the acquired images are transmitted to the embedded image processor in real time via the EtherCAT bus. S6: The processor sends a "rejection signal" to the PLC and marks the non-conforming type. After receiving the "rejection signal", the PLC pushes the non-conforming gear set from the turntable fixture to the scrap bin through the hydraulic push component (7).
