Description

Technical Field

[0001] The utility model belongs to the field of single polishing machine disk repair, in particular to a tool for repairing the single polishing machine disk. Background Art

[0002] The single-sided polishing machine has high pressure, high speed and high heat generation when in use, which will cause certain damage to the disc surface. In addition, water cooling is used to maintain the overall disc surface. Over time, the polishing disc is partially deformed and can only be removed for repair. After installation, it does not match the original single-sided polishing machine grinding head, which can easily cause the workpiece TTV (thickness change of the polishing disc), warping and other indicators to fail to meet the standards. In severe cases, it may cause the disc to be rubbed, and the entire workpiece and polishing film may be scrapped. Utility Model Content

[0013] Advantages: The positioning wheel acts as a limiter to prevent the grinding disc from moving during the repair process, which would affect the quality of the repair.

[0014] Furthermore, a plurality of bolt holes are arranged at intervals on the outer circumferential side surface of the single polishing machine grinding head, and a wheel mounting seat equipped with a positioning wheel is fixed in the bolt holes by bolts.

[0015] Furthermore, the positioning wheel and the coaxial wheel both use plastic-coated bearings.

[0016] Advantages: Plastic-coated bearings are light in weight, made entirely of lubricating materials, have low friction and long service life.

[0017] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented according to the contents of the specification. In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following preferred embodiments are specifically cited and described in detail with reference to the accompanying drawings.
