The utility model provides aluminum pipe inner wall spraying equipment, relates to aluminum pipe processing equipment technical field, including connecting block and machine body, the outer wall of connecting block is fixedly connected with two connecting seat, one end of connecting seat far away from connecting block is fixedly equipped with first motor, the output shaft of first motor is fixedly connected with rotating rod. During spraying work, the end of the aluminum pipe extrudes the outer surface of the cleaning head, then the cleaning head enters the aluminum pipe, pressure is applied to the cleaning head through a spring, the outer surface of the cleaning head is always attached to the inner wall of the aluminum pipe, and then the cleaning head is attached to the inner wall of the aluminum pipe to slide and rotate; dust and other impurities on the inner wall of the aluminum pipe can be efficiently cleaned, the falling impurities can be blown out through high-speed rotation of the fixing blocks, it is guaranteed that the cleanliness of the inner wall of the aluminum pipe meets the spraying requirement, it is guaranteed that the interior of the aluminum pipe can be evenly sprayed, the inner wall of the aluminum pipe is prevented from being corroded, and the service life of the aluminum pipe is prolonged.

This utility model discloses a cutting device for sintered metal mesh, relating to the field of sintered metal mesh processing technology. The utility model includes a worktable, a central rod, a support arm, and an I-shaped slider. A central rod is positioned at the center of the upper part of the worktable, with a pressure block rotatably connected to its bottom end. A support arm is rotatably connected to the lower outer circumference of the central rod, and an I-shaped slider is slidably inserted into the support arm. A servo motor is fixed to the top surface of the end of the I-shaped slider away from the support arm, and a rotating shaft is rotatably connected to the bearing. A cutting blade is fixed to the end of the rotating shaft away from the support arm. Support rods are fixed to both sides of the end of the I-shaped slider away from the support arm, and an arc-shaped pressure plate is fixed to the bottom of both support rods. This utility model, by setting up a worktable, support arm, I-shaped slider, cutting blade, central rod, pressure plate, and pressure block, solves the problems of not being able to cut circular sintered metal mesh in one go, the edges easily curling when cutting circular sintered metal mesh, and the inability to cut sintered metal mesh of different diameters.

This invention relates to the field of laser cutting equipment technology, specifically to a display screen laser cutting device and its usage method. The display screen laser cutting device includes a conveyor, a laser cutter, and an automatic quality verification component. The conveyor transports the display screen to be cut to the laser cutter. The automatic quality verification component verifies whether the display screen has been completely cut. The automatic quality verification component includes a mounting bracket, a detection card, and a photoelectric switch. The laser cutter and the mounting bracket are arranged sequentially along the conveyor's transport direction. The detection card is movably mounted on the mounting bracket. The photoelectric switch monitors the relative position of the detection card and the mounting bracket. The photoelectric switch is electrically connected to the conveyor's drive motor. This invention, through its automatic quality verification component, can automatically identify the cutting quality of the display screen, exhibiting a higher level of intelligence and effectively improving the processing efficiency of the display screen.

The utility model belongs to the technical field of notch polishing, and particularly relates to a plastic pipe notch polishing device which comprises a polishing table, a transmission belt is arranged in the polishing table, a pipe to be machined is placed on the top of the transmission belt, hydraulic machines are slidably installed on the two sides of one end of the top of the polishing table, and the output ends of the hydraulic machines are fixedly connected with driving motors. A polishing assembly is arranged at the output end of the driving motor; the grinding assembly comprises an assembly shell, a transmission ring is fixedly connected to the end, away from the driving motor, of the assembly shell, and an outer grinding head and an inner grinding head are arranged on one side of the transmission ring. According to the pipe polishing device, the diameter of the polishing head can be freely adjusted according to the requirement of a pipe through the design of the polishing assembly, the diameter of the polishing head on the inner side of the pipe can be changed through the design of the inner polishing assembly, and therefore the inner side and the outer side of a notch can be polished at the same time; and the pipe notches can be ground and beveled by adjusting the output distance of the hydraulic machine.

The invention relates to the technical field of orthopedic surgical instruments, in particular to an acetabulum file capable of continuously adjusting the size, which is used for solving the problem that the size of the existing acetabulum file is not easy to adjust, the acetabulum file comprises a transmission rod, the end part of the transmission rod is rotatably connected with a tool apron, and a plurality of blades are arranged on the tool apron in an annular array; the multiple blades jointly form the hemispherical acetabulum file head and can synchronously slide on the tool apron in the radial direction so as to be synchronously close to or away from each other, and therefore the size of the hemispherical acetabulum file head is adjusted. According to the acetabulum file, when the acetabulum file faces acetabulum with different sizes, the multiple blades are synchronously adjusted to synchronously linearly move towards the circle center position of the tool apron to be close to or far away from the circle center position, so that the diameter of the hemispherical tool bit formed by the multiple blades can be changed, and the acetabulum file is suitable for acetabulum with different sizes or different grinding requirements; and a plurality of acetabulum files with different sizes do not need to be alternately used.
