The application provides a compressor and an air conditioner, the compressor comprising: a shell, an inside of the shell being provided with a positioning structure, the positioning structure dividing the inside of the shell into a first containing cavity and a second containing cavity; a stator core, the stator core being arranged in the first containing cavity, and at least part of the positioning structure being connected with a first end of the stator core; a snap ring assembly, the snap ring assembly being arranged in the first containing cavity, the snap ring assembly comprising a plurality of clamping portions, the snap ring assembly being connected with a second end of the stator core through the clamping portions, and a first backflow channel being formed between adjacent clamping portions and between part of an outer wall of the stator core and part of a surface of the first containing cavity; and a pump body assembly, the pump body assembly being arranged in the second containing cavity, and the first backflow channel being arranged in communication with the second containing cavity. The path of vibration transmission of the stator core to the shell can be blocked, an efficient oil return channel can be constructed to improve the oil return efficiency of the compressor, and the problems of excessive vibration and noise of the motor part of the compressor and low heat dissipation efficiency of the motor can be solved.

The utility model provides a motor end cover structure and a motor, the motor end cover structure comprises a cover body, a bearing seat and a reinforcing rib assembly, the outer periphery of the cover body is provided with an annular projection, the bearing seat is arranged on the cover body, and an annular installation space is formed between the inner wall surface of the annular projection and the outer wall surface of the bearing seat. The reinforcing rib assembly comprises first reinforcing ribs and second reinforcing ribs, the multiple first reinforcing ribs are arranged in the circumferential direction of the bearing seat at intervals, one ends of the first reinforcing ribs are connected with the bearing seat, and the other ends of the first reinforcing ribs extend in the radial direction of the cover body and are connected to the annular protrusion; a second reinforcing rib is arranged between every two adjacent first reinforcing ribs, and the distance between the first end of each second reinforcing rib and the axis of the bearing seat is smaller than the distance between the second end of each second reinforcing rib and the axis of the bearing seat. The structure that the first reinforcing ribs and the second reinforcing ribs are arranged in a matched mode can solve the problem that in the prior art, a motor end cover cannot overcome tangential vibration, and consequently the performance of a motor is affected.

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.
