Problems solved by technology
The existing shaving structure adopts the cylindrical surface of the hard core shaft and the positioning of the shaft end surface, and the end surface of the product is pressed by the washer and the nut for shaving processing. When the next workpiece is replaced after each processing, all the nuts and washers must be removed. , to replace the workpiece, using this structure, it takes a long time to replace the workpiece, and the operation is inconvenient
In addition, when the product is compressed by nuts and washers, uneven force on the pressing surface leads to inaccurate positioning of the product, resulting in low shaving precision. When producing sun gears, the precision requirements for each gear are particularly high. Using the above shaving structure Unable to meet the requirements, there is an urgent need for a shaving structure with simple structure, convenient operation and high shaving precision

The invention proposes a high-precision auxiliary structure. The high-precision auxiliary structure comprises a mandrel, wherein the mandrel comprises a mandrel body, a mandrel ring, a mandrel neck and a mandrel head arranged from left to right; an outer spiral groove is formed in the outer circular surface of the mandrel head; the mandrel head is coated with a pressing sleeve; an inner spiral groove is formed in the inner wall of the pressing sleeve; an annular groove communicated with the inner spiral groove is formed in the right wall of the right end of the pressing sleeve; an oil tank is formed in the outer surface of the mandrel neck; and an annular permanent magnet is inlaid in the edge of the left end surface of the pressing sleeve. The high-precision auxiliary structure is simple in structure, convenient for operation and high in gear shaving precision.
Description
technical field [0001] The invention relates to the field of machining, in particular to a high-precision auxiliary structure. Background technique [0002] Shaving is a key process in gear manufacturing. The precision of shaving directly determines the final precision of the gear. In addition to the performance of the shaving machine, the accuracy of the tool, and the level of operation, the quality of the shaving structure also directly affects the quality of the shaving machine. tooth precision. The existing shaving structure adopts the cylindrical surface of the hard core shaft and the positioning of the shaft end surface, and the end surface of the product is pressed by the washer and the nut for shaving processing. When the next workpiece is replaced after each processing, all the nuts and washers must be removed. , to replace the workpiece, using this structure, the time to replace the workpiece is long, and the operation is inconvenient. In addition, when the produ...
