Description

Technical Field

[0001] The utility model relates to the technical field of mechanical bearing processing, in particular to a pressing device for mechanical bearing processing. Background Art

[0002] Bearing is an important component in contemporary mechanical equipment. Its main function is to support mechanical rotating bodies, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The general process of bearing processing includes bearing steel raw materials, turning into inner sleeves, outer sleeves, and bead blanks, heat treatment, grinding into finished products (grinding processes include internal cylindrical grinding, external cylindrical grinding, and centerless grinding), and assembling finished products. Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling elements, and cage. The function of the inner ring is to cooperate with the shaft and rotate with the shaft; the function of the outer ring is to cooperate with the bearing seat and play a supporting role; the rolling elements are evenly distributed between the inner ring and the outer ring with the help of the cage. The shape, size, and number of the rolling elements directly affect the performance and life of the rolling bearing. The cage can evenly distribute the rolling elements, guide the rolling elements to rotate, and play a lubricating role. At present, when assembling the bearing, a tool is needed to press the inner gear ring into the inside of the bearing ring.

[0003] According to the patent application number 201921945565.1, a bearing pressing device for machining is disclosed, including a base, a support seat, a frame and a support cylinder, the support seat is installed in the middle of the base by bolts, and a plurality of pressing cavities are arranged on the support seat; the frame is vertically fixed on both sides of the base, a support plate is installed on the top of the frame, and a pressing drive mechanism is installed on the support plate; the pressing drive mechanism includes a motor, a cam, a push plate, a push rod and an upper pressing block, the motor is fixed on the support plate through the support seat, and the output end of the motor is connected to the cam; one end of the push plate cooperates with the cam, and the end of the push plate away from the cam is connected to the push rod and is in a T shape with the push rod, a first spring is sleeved on the push rod, the first spring is connected between the push plate and the support plate, and the end of the push rod passes through the support plate and is connected to the upper pressing block.

[0004] By adopting the above scheme, the impact force output by the pressing drive mechanism does not directly act on the bearing workpiece through the cooperation of the pressure plate and the pressing plate, thereby avoiding impact on the bearing workpiece, and the gear ring can be quickly pressed into the bearing. However, the above scheme only calibrates the gear ring and the bearing ring to be concentric by visual observation, and there is a certain error in visual observation, so when the gear ring is pressed down, it may be damaged due to the deviation of the gear ring; for this reason, we provide a pressing device for mechanical bearing processing to solve the above problems.
