Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to a bearing processing three-process grinding machine. Background Technology

[0002] Bearings are crucial components in modern machinery, primarily functioning to support rotating parts, reduce friction, and ensure rotational accuracy. Their manufacturing process is complex, involving multiple stages including forging, annealing, machining, heat treatment, and grinding. Grinding, especially the grinding of rolling surfaces, is a critical step determining bearing precision, directly impacting bearing life and vibration / noise reduction performance. The strict tolerances for the inner diameter of bearing rings necessitate highly precise grinding machines to ensure dimensional accuracy and surface quality.

[0003] Traditional grinding machines typically can only complete a single operation at a time. For example, an external cylindrical grinding machine can only grind the outer diameter of a bearing, while an internal cylindrical grinding machine can only machine the inner diameter. To complete multiple grinding operations on a bearing, different parts of the same bearing need to be clamped and machined multiple times on different grinding machines. This not only consumes a lot of time and manpower, but may also lead to cumulative errors due to multiple clamping operations, affecting the bearing's accuracy. Utility Model Content

[0004] This invention addresses the technical problem that traditional grinding machines can typically only complete a single process at a time, requiring multiple clamping and processing on different grinding machines to process different parts of the same bearing, thus affecting bearing performance. It provides a three-process grinding machine for bearing processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bearing processing three-process grinding machine, comprising: a frame, a slide rail connected inside the frame, a transmission box slidably connected on the slide rail, the transmission box being able to slide along the slide rail self-locking, a turntable rotatably connected inside the transmission box, the output end of the transmission box being connected to the turntable, an eccentrically formed groove on the turntable, a support portion of a grinding motor slidably connected inside the groove, a threaded shaft rotatably connected inside the turntable, the threaded shaft being threadedly connected to the support portion of the grinding motor, the output end of the grinding motor being connected to a grinding rod, the grinding rod being connected to a grinding head, three clamping ring frames connected along the axial direction of the grinding rod on the frame, the upper part of the clamping ring frames being concentrically arranged with the grinding rod, each clamping ring frame being concentrically connected to a corresponding centering fixture, a through hole being formed at the center of the clamping ring frame, the centering fixture being hollow, and an outer ring, a flange, and an inner ring being sequentially clamped in different centering fixtures along the axial direction from the grinding rod to the grinding head.

[0006] Preferably, the grinding motor is powered by its own battery.

[0007] Preferably, a threaded shaft is rotatably connected inside the frame, and the threaded shaft is threadedly connected to the transmission box.

[0008] Preferably, the centering fixture includes a worm gear, which is rotatably connected to the upper part of the fixture ring frame. The worm gear meshes with a worm wheel, which is connected to a sleeve. The sleeve is rotatably connected to a through hole. A scroll guide rail is connected to the side of the worm wheel, which meshes with the bottom teeth of the gripper. The gripper is slidably connected to a gripper slide rail, which is connected to the fixture ring frame. Different clamping plates are connected to the grippers of different centering fixtures.

[0009] Compared with the prior art, the beneficial effects of this utility model are: Using three concentric clamps, the inner ring, outer ring, and flange of the bearing are concentrically clamped at one time. The inner rings of the three parts are concentrically precision ground by passing the grinding rod and grinding head through the through hole. By concentrically clamping and concentrically precision grinding the three parts of the same bearing, the concentricity of the bearing after grinding is greatly improved.

[0010] The grinding motor is powered by its own battery, which avoids the wire tangling when rotating eccentrically. Moreover, the torque required for fine grinding is not high, and the battery can fully supply low-torque grinding. Attached Figure Description
