Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, in particular to a photovoltaic main shaft connector and a bearing testing tool. Background Art

[0002] In the bearing wear life test, since the spindle and plastic bearings have multiple specifications, the existing test fixture can only test the spindle and plastic bearings of one specification at a time. After the test of the spindle and plastic bearing of one specification is completed, the spindle and plastic bearing of the next specification must be replaced. The test efficiency is low and the operation is cumbersome. For this reason, we proposed a photovoltaic spindle connector and bearing test fixture. Utility Model Content

[0003] The purpose of the utility model is to provide a photovoltaic main shaft connector and bearing testing tool to solve the problems of low testing efficiency and cumbersome operation in that the existing testing tool proposed in the background technology can only test the main shaft and plastic bearing of one specification at a time, and can only replace the main shaft and plastic bearing of the next specification after the test of the main shaft and plastic bearing of one specification is completed.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a photovoltaic main shaft connector for clamping photovoltaic main shafts of different specifications and sizes, comprising a clamp (1), characterized in that: a plurality of clamps (1) are provided, the clamp (1) comprising a first connecting portion (2), a second connecting portion (3) and a connecting plate (4), the first connecting portion (2) and the second connecting portion (3) are located on the same axis, the connecting plate (4) is located between the first connecting portion (2) and the second connecting portion (3), and the ends of the first connecting portion (2) and the second connecting portion (3) close to the connecting plate (4) are respectively welded to the corresponding side surfaces of the connecting plate (4).

[0005] A first connecting portion and a second connecting portion are provided on the clamp to match two main shafts of different specifications and sizes. By arranging two identical clamps on both sides of the main shaft, the main shaft is clamped and fixed. By welding the connecting plate to the connection between the first connecting portion and the second connecting portion, the strength of the clamp can be increased.

[0006] In some embodiments, the tops of the first connecting portion (2) and the second connecting portion (3) are both provided with waist holes (5). The waist holes are used to securely connect the main shaft and the clamp, and the waist holes are designed to be long strips to facilitate adjustment of the position of the main shaft.

[0007] In some embodiments, the bottoms of the first connecting portion (2) and the second connecting portion (3) are both provided with an outwardly extending extension portion (6), and the extension portion (6) is provided with at least one through hole (7). The through hole is used to securely connect the two clamps on both sides of the main shaft.

[0008] In some embodiments, a plurality of the clamps (1) pass through the waist hole (5) and the through hole (7) via fasteners (8) to clamp and fix the photovoltaic main shaft. The fasteners are bolts, which pass through the through holes on the clamps on both sides of the main shaft to fix the two clamps.

[0009] In some embodiments, the bottom of the connecting plate (4) is flush with the lower surface of the extension portion (6), ensuring that the two clamps can be stably clamped on both sides of the main shaft to avoid deviation.

[0010] The present application also provides a bearing testing tool, including a first main shaft, a second main shaft, a first bearing ring seat installed on the first main shaft, a second bearing ring seat installed on the second main shaft, a first motor fixedly connected to the first main shaft, and a second motor fixedly connected to the second main shaft. The first main shaft and the second main shaft are fixedly connected by the photovoltaic main shaft connector to form a whole.

[0011] The technical effects of this application are:

[0012] By providing a clamp with a first connecting part and a second connecting part that can match two specifications of main shafts, it is possible to connect two specifications of main shafts at the same time, so that the two specifications of main shafts and their plastic bearings can be tested for wear resistance at the same time, saving space and improving test efficiency.
