The invention discloses a grinding device for a metal pipe. The grinding device comprises a machining table, grinding mechanisms and a clamping rotation mechanism, wherein a portal support frame is arranged on the machining table; the clamping rotation mechanism is arranged at the top of the portal support frame; two grinding mechanisms are arranged, and arranged at the two sides of the corresponding clamping rotation mechanism on the machining table; and each grinding mechanism comprises an installation fixing plate, an adjustment rod, a grinding abrasive belt installation frame, a grinding abrasive belt and a first drive motor. The grinding device disclosed by the invention is reasonable in structural design; through the design that a pipe clamping mechanism and the grinding abrasive belts are both equipped with motor drive structures, the grinded metal pipe and the grinding abrasive belts are both capable of automatically rotating, so that the grinding speed and the grinding efficiency are increased; and meanwhile, the crisis-fighting capacity of the device is improved, and the normal grinding machining of the device is not influenced in the case that the drive motor of any of the pipe clamping mechanism and the grinding abrasive belts is damaged, so that the machining progress for the product is ensured.

The invention relates to the mechanical polishing field, in particular to a rubber plate polishing device. The rubber plate polishing device comprises a frame, wherein a rubber plate fixing apparatus is arranged on the upper surface of the frame; guide rails and racks are arranged at the edges of two unconnected sides of the rubber plate fixing apparatus; a walking device is arranged on one side of the rubber plate fixing apparatus with the guide rails and the racks; gears are arranged at the lower part of the walking device, engaged with the racks on the rubber plate fixing apparatus and placed on a wheel; an automatic distance adjusting device is arranged at the front end of the walking device; a polishing wheel device is arranged at the front end of the automatic distance adjusting device; the polishing wheel device is connected with a polishing wheel rotating device; and the polishing wheel rotating device drives a cylinder on the polishing wheel device to rotate. The rubber plate polishing device provided by the invention has the advantages that the whole rubber plate can be polished, the polishing speed of the rubber plate is effectively increased, the polishing quality of the rubber plate is effectively improved, the labor intensities of workers are greatly reduced and a great deal of manpower and material resources are saved.

The invention discloses a pantograph slide plate double-head grinding device. The pantograph slide plate double-head grinding device comprises a flat plate type linear motor fixedly arranged on the ground and supports. The upper end of a rotor of the flat plate type linear motor is fixedly provided with a mounting column. A transmission shaft is mounted on the side face of the mounting column in arolling mode. The upper end of the mounting column is fixedly provided with a rotation motor driving the transmission shaft to rotate through a transmission mechanism I. One end of the transmission shaft I is fixedly provided with a push rod motor. A grinding mechanism is fixedly mounted on the head of a push rod of the push rod motor. A cross beam fixedly mounted on the supports is arranged above the grinding mechanism. The pantograph slide plate double-head grinding device has the beneficial effects that through the pantograph slide plate double-head grinding device and a grinding method thereof, the two side faces of a pantograph slide plate can be ground simultaneously; the pantograph slide plate does not need to be fixed manually in the grinding process; grinding workers are liberated; the labor intensity of the grinding workers is reduced; the grinding speed and efficiency are remarkably improved; time and labor are saved; and the pantograph slide plate double-head grinding device is good in practicality.

The invention discloses an electric power assisted worm grinding process and relates to the technical field of worm processing. The electric power assisted worm grinding process comprises the step of(1), pretreatment of a worm, specifically, spraying a rust remover to the surface of the worm to be ground, conducting simple grinding on the surface of the worm through abrasive paper, cleaning the worm in clean water, soaking the worm in 60-80% alcohol liquid for 5-10 min and then taking out and draining off the worm. According to the electric power assisted worm grinding process, before grinding, the surface of the worm is soaked through alcohol to remove impurities on the surface of the worm; an oxidation film on the surface of the worm is removed through acid treatment to prevent the grinding process from being impeded by the oxidation film; and finally, the surface of the worm is softened through normalizing treatment, at the moment, the surface and the interiors of tooth gaps of theworm can be ground through back-and-forth cooperation of a plurality of grinding cams on a grinding device, and burrs and protrusions on the softened surface of the worm are ground and removed. Through the electric power assisted worm grinding process, the grinding speed is increased, and the grinding precision is improved.
