Description

Technical Field

[0001] This utility model relates to the field of bearing synchronous alignment technology, and in particular to a synchronous alignment mechanism for the inner and outer rings of an automatic bearing assembly machine. Background Technology

[0002] In the manufacturing process of bearings, the assembly process is a crucial step to ensure their performance and precision. In particular, the alignment of the inner and outer rings directly affects the bearing's rotational accuracy, service life, and operational stability. Traditional bearing assembly relies heavily on manual labor, requiring workers to manually align the inner and outer rings. This process is not only labor-intensive and inefficient, but the subjectivity and instability of manual operation can also lead to insufficient alignment accuracy, resulting in problems such as eccentricity and tilting, which seriously affect the consistency of bearing quality. With the continuous improvement of automation in the manufacturing industry, automatic bearing assembly machines are gradually replacing manual operation and have become important equipment for improving production efficiency and ensuring product quality.

[0003] For bearings of different models and sizes, frequent replacement of positioning components or complex parameter adjustments are often required to meet alignment requirements. This not only increases equipment debugging time and reduces production efficiency but also significantly increases production costs. Furthermore, existing technologies still suffer from the problem of synchronous alignment between the inner and outer rings of the bearing. Currently, the market addresses this by dividing positioning components into a basic module and a replaceable adjustment module. The basic module remains fixed, while the adjustment module is standardized according to the dimensional parameters of the inner and outer rings of the bearing. A quick-connect structure using slide rails and bolts achieves precise docking with the basic module. However, the problem of synchronous alignment between the inner and outer rings of the bearing still exists in existing technologies. This directly affects the bearing's rotational accuracy, causing significant vibration and noise during operation and reducing the stability of the equipment. Especially for high-precision mechanical equipment, such accuracy deviations can lead to malfunctions. Summary of the Invention

[0004] To overcome the above deficiencies, this utility model provides a synchronous alignment mechanism for the inner and outer rings of an automatic bearing assembly machine, aiming to improve the problem that the inner and outer rings of bearings cannot be synchronously aligned in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a synchronous centering mechanism for inner and outer rings of an automatic bearing assembly machine, comprising a frame, a motor fixedly connected to the top of the outer wall of the frame, a rotating shaft fixedly connected to the output end of the outer wall of the motor, a small gear fixedly connected to the top of the outer wall of the rotating shaft, a large gear meshing around the outer wall of the small gear, a push rod slidably connected to the middle of the outer wall of the large gear, a limit ring slidably connected around the outer wall of multiple push rods, a fixed frame fixedly connected to the top of the outer wall of the frame, a connecting ring fixedly connected to the bottom of the outer wall of the fixed frame, a motor fixedly connected to the bottom of the outer wall of the connecting ring, a gear shaft fixedly connected to the output end of the motor, a disc meshing around the outer wall of the gear shaft, a gear groove formed in the middle of the outer wall of the disc, a push rod slidably connected to the top of the outer wall of the disc, and a balancing mechanism fixedly connected to the bottom of the outer wall of the frame, the balancing mechanism being used to balance the device.
