The invention discloses a series of processing technology for liquid-supply optical surface in the center of sub-aperture. The series of processing technology is a systematic process method from blank surface to ultra-smooth surface based on the principle of hydrodynamic pressure, mainly including the grinding and polishing process of hydrodynamic pressure consolidated abrasive , center liquid supply small grinding head polishing process and disk hydrodynamic pressure polishing process. The sub-aperture central liquid supply optical surface processing tool includes an elastic coupling, a polishing disc, and a polishing pad. The two ends of the flexible coupling are respectively connected to the polishing disc and the rotating shaft. Pads and polishing pads to realize the successive recursive suppression process of optical surface low frequency, medium frequency and high frequency errors. At the same time, in order to obtain a high-quality, low-damage ultra-precision smooth surface, the combined application of different grinding and polishing pads, after the previous process polished the surface, the residual sub-surface damage layer was removed and no new sub-surface damage was formed. Multiple processing minimizes subsurface damage.

The invention discloses an intelligent clamping transmission mechanism, which is characterized in that it includes a backboard, a workbench, a left mechanical arm, a right mechanical arm, a mechanical arm track, a left arm lifting device, a right arm lifting device, a left arm deceleration sensor, Left arm alignment sensor, right arm deceleration sensor and right arm alignment sensor. The intelligent clamping and conveying mechanism of the present invention can automatically detect the position of the object and intelligently clamp the object through the sensor, and can transmit the object at high speed after the object is clamped. An intelligent clamping transmission mechanism of the present invention, in the process of clamping and moving, directly uses switch value control instead of directly using digital control, and has high intelligence, strong anti-interference ability, simplified control system, safety and efficiency and No damage to the orderliness of the object and other characteristics.

The invention provides a flexible joint bearing structure. The flexible joint bearing structure effectively ensures that an outer ring of a joint bearing is in flexible contact with a shell during mechanical connection, effectively avoids the bearing damage caused by the abrasion of a bearing in use, and prolongs the service life of the bearing, thereby reducing the production cost. The flexible joint bearing structure comprises an outer ring and an inner ring and is characterized in that the outer ring is made from a flexible material.

The invention discloses a floating type leaf-stripping roller for a sugar cane harvester. The floating type leaf-stripping roller comprises a power input shaft, a roller rack, a leaf-stripping plate, clamping plates, a limit spring and the like. Six rib plates are radially welded to the roller rack. A plurality of mounting holes and spring limit holes are evenly distributed in each rib plate. The longitudinal section of the leaf-stripping plate is of an inverted-T shape, the upper portion of the leaf-stripping plate is evenly provided with V-shaped grooves, and a plurality of protruding teeth are machined in each V-shaped groove. The L-shaped clamping plates are provided with a plurality of mounting holes corresponding to the rib plates. The leaf-stripping plate is elastically connected with the rib plates through a plurality of limit springs mounted in the spring limit holes. The clamping plates are mounted on two sides of the rib plates of the roller rack through bolts and clamp the leaf-stripping plate. The floating type leaf-stripping roller has the advantages that the adaptability of the leaf-stripping roller to sugar canes of various diameters can be improved effectively, the contact area of the V-shaped grooves and the sugar canes is increased, flexible contact of the sugar canes and the leaf-stripping roller is guaranteed, sugar cane blocking and breaking probability is lowered, and stripping efficiency is increased.

The invention provides a checking fixture for measuring the depth of a bottom hole of a valve retainer of an engine cylinder cover, and the checking fixture is used for completing detection of the depth size of the bottom hole of the valve retainer of the engine cylinder cover. The checking fixture comprises a measurement execution mechanism, a displacement transmission mechanism, a support and control mechanism and a measurement data display mechanism, wherein the measurement execution mechanism comprises a guide measuring rod, a flange base and a flange cover; the guide measuring rod is located at the lower end of the checking fixture and consists of a measuring head and a connection base; the bottom face of the connection base is a test reference surface; the top end of the connection base is fixedly connected with the corresponding element of the support and control mechanism; the flange base is in an inverted disk structure; a large round hole is arranged on the top face of the flange base, and the bottom face of the flange base is provided with a measuring face; the flange cover is fixedly mounted on the top face of the flange base; and a disk-shaped groove is arranged at the center of the flange cover; and the disk-shaped groove is connected with a peripheral framework through three ribs. The checking fixture disclosed by the invention has the advantages of compact structure and simplicity in operation. The detection precision of a working piece to be measured can be ensured, and the service life of the checking fixture is prolonged.
