Description

Technical Field

[0001] The utility model belongs to the technical field of bearing sleeve cutting, and in particular relates to a cutting device for processing a bearing sleeve. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. When bearings are first produced, the pipes need to be cut into the required size to be used as bearing sleeves.

[0003] The patent with application number 202222731518.5 discloses a cutting device for bearing sleeve production and processing, including a base, a clamping and feeding mechanism arranged on the base, a rotating mechanism installed at one end of the clamping and feeding mechanism, a limit assembly arranged near the other end of the clamping and feeding mechanism, and a driving and cutting mechanism, wherein the clamping and feeding mechanism includes a cylinder, a first motor, a lead screw and a limit adjustment part, and both ends of the cylinder are supported by a support plate fixed on the base. By setting up the clamping and feeding mechanism, the first motor is started to drive the lead screw to rotate, so that the limit adjustment part moves along the notches on the upper and lower sides of the cylinder toward one side of the limit assembly, driving the pipe to move synchronously to the length required for cutting and then stop feeding.

[0004] The above technical solution utilizes a clamping and feeding mechanism to transport and clamp the bearing sleeve raw material. Since the bearing sleeve raw material needs to be clamped and fixed before each cutting, and separated and fed after cutting, the cutting steps of the bearing sleeve are cumbersome. In addition, the above technical solution adjusts the cutting length of the pipe by driving a motor. After the motor stops rotating, the transmission mechanism inside it and the inertia of the pipe will cause it to move excessively, thereby affecting the accuracy of pipe cutting.
