The present application relates to a railway rail polishing device. The traditional post-welding rail polishing mainly relies on manual operation of a hand-held grinder, which is time-consuming and laborious, and the operating environment is poor, which can easily cause occupational diseases of workers. The present application comprises two fixed arms, which are symmetrically wrapped on both sides of the rail, and the top of the two fixed arms are hingedly connected to each other. The side of the fixed arm in contact with the rail is provided with a containing groove. A position limiter is sleeved on the top hinged portion of the fixed arm, and a power assembly is arranged on the position limiter. The power assembly is engaged with the polishing belt. The polishing belt is annular, and the polishing belt is wrapped around the outer periphery of the fixed arm and the position limiter, and is simultaneously arranged in the containing groove on the inner side of the fixed arm and tightly contacts the rail. A plurality of abutting assemblies are arranged in the containing groove of the fixed arm and abut the side of the polishing belt away from the rail. The present application not only saves labor consumption, but also realizes automatic polishing and dust reduction, thereby ensuring the health of the polishing environment and avoiding harm to workers.

The utility model relates to the technical field of polishing devices, in particular to an alloy audio cable connector polishing device. The polishing device comprises a rack, a rotating chassis and an adjusting assembly, two oppositely-distributed limiting plates and a plurality of hydraulic cylinders are arranged on the rack, a top plate is arranged at the output ends of the hydraulic cylinders, and two oppositely-distributed polishing assemblies are arranged on the top plate; the rotating base plate is rotationally arranged on the rack, and a rotating top plate is detachably arranged on the rotating base plate; the adjusting assemblies are evenly arranged on the rotating base plate in the annular direction, and each adjusting assembly comprises an air cylinder arranged on the rotating base plate, a pulling plate arranged at the output end of the air cylinder, two adjusting plates arranged on the pulling plate in a relatively sliding mode and rolling wheels b rotationally arranged on the adjusting plates. The pulling plate is driven by rotating the air cylinder on the base plate, the multiple idler wheels b are matched with the limiting plate to convey connectors to the position below the grinding assembly one by one, and therefore the grinding efficiency of the connectors is improved.

This invention provides an automated femoral condyle grinding device and method. The device includes: an articular surface grinding mechanism for grinding the articular surfaces of the workpiece; an intercondylar grinding mechanism for grinding the intercondylar region of the workpiece; a workpiece adjustment mechanism for adjusting the position of the workpiece held by a robotic arm, ensuring the workpiece fits against a positioning reference surface; the end of the robotic arm can be selectively fitted with a first or second clamp; the robotic arm moves the gripped workpiece to the articular surface grinding mechanism for grinding the articular surfaces; the robotic arm can be replaced with the second clamp from a clamp magazine and move the workpiece to the intercondylar grinding mechanism for grinding the intercondylar region. This invention automates the grinding of the workpiece, solving the problems of slow grinding efficiency and unstable grinding quality caused by existing manual grinding of the femoral condyle.

This invention discloses a cavity grinding device for die-casting mold manufacturing, relating to the field of die-casting mold manufacturing technology. It includes a machine base, a processing table fixedly connected to the top surface of the machine base, a first linear motor on one side of the machine base, and a guide rod on the other side of the machine base. The mover of the first linear motor is fixedly connected to a gantry frame, with the side of the gantry frame away from the first linear motor sleeved on the guide rod. This invention, through the cooperation of the X-axis and Y-axis linear motors, facilitates precise adjustment of the grinding position, improving grinding positioning accuracy, and thus enabling automated grinding of the mold cavity and inner wall of the channel. The cooperation of the first motor and the wire brush roller facilitates efficient grinding of the cavity and inner wall of the channel, improving grinding smoothness and ensuring mold processing accuracy. The cooperation of the air jet, conical nozzle, vacuum machine, and air outlet pipe facilitates timely removal of metal debris generated during grinding, improving debris cleaning efficiency.

This application discloses an automatic grinding device for angle steel saw blades, relating to the technical field of metal processing equipment. It includes a base, a positioning shaft, a fixing structure, an angle steel saw blade feeding mechanism, a damping braking mechanism, and a grinding mechanism. The feeding mechanism drives the saw blade to rotate and controls each rotation by one tooth pitch angle, achieving precise feeding of the saw blade. The damping braking mechanism eliminates the rotational inertia of the saw blade, allowing it to stop accurately. The grinding mechanism precisely grinds each tooth of the saw blade, ensuring grinding quality and achieving automated grinding of angle steel saw blades, thus improving grinding efficiency and quality.

This utility model provides an automatic knife sharpener, including a housing and a sharpening assembly. The sharpening assembly is movably fixed inside the housing via a stroke component and moves back and forth within the housing. The sharpening assembly includes a base, a grinding wheel, and a support component. The housing is provided with a knife inlet and a switch. The housing contains a circuit board and a water pump. The switch controls the opening and closing of the sharpening assembly, the stroke component, and the water pump via the circuit board, which can realize the automatic sharpening of the knife edge, eliminating cumbersome steps in the sharpening process, making operation convenient and improving the user experience.

This invention discloses a raw material extraction device for detecting anthocyanin content in pure black rice breeding materials, relating to the field of anthocyanin extraction technology in pure black rice breeding materials. The device includes a main structure comprising an extraction tank. A support is fixedly installed on the bottom surface of the extraction tank, and a tank lid is fixedly installed on the upper surface of the extraction tank. A discharge pipe is fixedly connected to the bottom of the extraction tank, and an extraction processing mechanism is provided on the outside of the extraction tank. This raw material extraction device for detecting anthocyanin content in pure black rice breeding materials, through a grinding and air separation unit, can precisely grind the pure black rice breeding materials using grinding rollers, efficiently separating the rice husks from the rice grains. After filtration through a filter screen, the pure rice grains and seed coats enter the extraction tank through the husks, while the broken rice husk impurities are discharged through the discharge chamber. This achieves automated grinding, screening, and conveying of the raw materials, effectively solving the problem of rice husks hindering the contact between the extraction solvent and anthocyanins.
