The invention discloses a parallel polishing, paint spraying and drying sheet spraying system which comprises a polishing room and a paint spraying and baking room connected with the polishing room, wherein a lifting heat-preservation roller shutter door is arranged between the polishing room and the paint spraying and baking room; a rail is arranged on the ground of each of the polishing room and the paint spraying and baking room; sliding trolleys are arranged on the rails. The parallel polishing, paint spraying and drying sheet spraying system is reasonable in structural design, high in operability, completeness, automation degree and safety, and is energy-saving and environment-friendly, labor hours can be greatly saved particularly, the machining efficiency is more than 3 times higher than that of the prior art, high-quality air environments in the whole polishing and paint spraying and baking rooms can be ensured, stable and reliable temperature heating conditions and illumination requirements in the polishing and paint spraying and baking rooms are met, the painted surface of a manufactured automobile workpiece has good mirror effects, and is high in compactness, firmness and anticorrosive performance, and good technical effects are achieved.

The invention relates to the technical field of jewelry processing equipment, and discloses a device for polishing inner holes of jewelry by utilizing a centrifugation principle. The device for polishing the inner holes of the jewelry by utilizing the centrifugation principle comprises a box body, wherein rotary pipes are connected in a polishing device, an inclined hole is formed in the outer side of the lower end of each rotary pipe in a surrounding mode, a drive device is connected with the outer side of each rotary pipe, a coil is arranged in each drive device, a fixing disk is connected with the outer side of the upper end of each rotary pipe, and a permanent magnet is connected with the outer side of each fixing disk in a surrounding mode. According to the device for polishing the inner holes of the jewelry by utilizing the centrifugation principle, a magnetic field opposite to the permanent magnet is generated by the coil, the magnetic field generated by the coil pushes the permanent magnet to rotate, the permanent magnet drives the rotary pipes to rotate through the fixing disk, the inclined holes in the lower ends of the rotary pipes spray water or water-sand mixed liquidfor polishing the inner holes of the jewelry, and the structure achieves the effect of evenly polishing the inner holes of the jewelry, and avoids the problems that due to vibration of a motor and a polishing rod of an existing polishing device, the diameter of the inner holes of the jewelry is different from the top down, and abrasion is easily caused to the jewelry.

The invention relates to the field of production of optical glass, in particular to an optical glass recycling process. The optical glass recycling process comprises the following steps that 1, an optical glass smashing device is prepared; 2, optical glass is cut; 3, the optical glass is unloaded into receiving sliding grooves; 4, a separation unit separates waste optical glass from optical glasson a supporting board; 5, the waste optical glass is crushed into optical glass particles through a crushing nail; and 6, the optical glass particles slide to receiving cloth, the two receiving sliding grooves are driven to get close to each other, and the optical glass inside the receiving sliding grooves is polished. By the adoption of the technical scheme, leftover materials can be automatically smashed and collected, and the optical glass is polished at the same time.

The invention discloses a double-sided deburring device, which comprises a controller, a transmission mechanism, a deburring mechanism and an overturning mechanism, and the controller is respectively connected with the transmission mechanism, the deburring mechanism and the overturning mechanism; the transmission mechanism includes One-way intermittent drive mechanism and several linearly arranged fixed pins advanced by the drive mechanism, there are at least four deburring mechanisms, and the four deburring mechanisms are divided into two groups and are arranged opposite to each other on On the left and right sides above the linearly arranged fixed pins, the turning mechanism is located between the deburring mechanisms on the same side of the linearly arranged fixing pins, and there are two turning mechanisms; the present invention uses an intermittent driving mechanism The workpiece can be propelled intermittently to increase the grinding time of the workpiece at one station, and during the grinding process, the drive mechanism can also improve the stability of the workpiece and prevent it from deviating from the grinding position, thereby ensuring grinding and removal glitch effect.

The invention discloses a processing technology for removing the fast opening of a pump core by rolling with an oil pressure jack, which specifically includes the following steps: S1, blanking a sheet material to form a pump core, and extruding and forming an annular notch at the end of the pump core; S2. Insert the pump core into the tooling fixture of the machine tool, and the annular notch is located on the outside of the tooling fixture; S3. Take two rolling knives and align them with the inner walls on both sides of the same annular notch, and press the two rolling tools The tools are synchronously fed to the inside of the annular notch, the tooling fixture drives the pump core to rotate, and the two rolling knives roll and grind the inner walls on both sides of the annular notch at the same time. The invention improves the grinding efficiency of the pump core annular notch. integrity.
