2results about How to "Good accuracy and stability" patented technology

This invention discloses an integrated power device combining a low-tooth-difference reducer and a motor, comprising a motor, a housing, and an output shaft coaxially arranged, with the housing rotatably connected to the output shaft. The housing has a hollow cavity inside, into which the motor output shaft extends and is linked via a reduction mechanism. A camshaft is connected to one end of the motor output shaft near the output shaft. The reduction mechanism includes a needle roller bearing mounted on the camshaft, a drive gear mounted on the needle roller bearing, and a transmission assembly installed between the drive gear and the output shaft. The inner wall of the housing has an internal gear ring, with the drive gear meshing with the internal gear ring using low-tooth-difference gears. This invention improves transmission stability and efficiency by designing the motor output shaft and camshaft as an integrated unit, while also making the space more compact. The drive gear and output shaft are driven by transmission steel balls, allowing the output end to directly bear radial force. The structure is simplified, with fewer parts, easier control of part machining accuracy, and lower manufacturing costs.

This invention relates to a universal contour detection device and assembly method for assisted robotic optical processing, belonging to the field of advanced optical manufacturing technology, and solves the technical problem of the lack of an in-situ high-precision detection device in the optical processing of large-aperture mirrors by robotic arms in the prior art. The contour detection device includes: a workpiece turntable and a swing-arm air-floating turntable; a workpiece table is provided on the upper surface of the workpiece turntable; the workpiece to be measured is placed on the workpiece table; the upper end of the swing-arm air-floating turntable is connected to the end effector of the robotic arm via a quick-change detection fixture; the lower end of the swing-arm air-floating turntable is connected to the arm via an arm fixture; a probe is provided at one end of the arm, which is located near the upper surface of the workpiece to be measured. In the contour detection device of this invention, the end effector of the robotic arm remains stationary during the measurement of the optical element's surface shape; compared to the measurement mode of a moving probe at the end effector, the accuracy and stability of the robotic arm in the stationary state are better.
