Embodiment Construction
[0012] As shown in the accompanying drawings, a gear single-tooth quenching method is carried out according to the following steps:
[0013] A. Process the first tooth: place the workpiece to be processed on the Y-axis motor rotating frame, the Z-axis motor drives the table to move vertically, and the X-axis motor drives the table to move horizontally, so that the sensor drops to the workpiece Below, the sensor starts to heat and start auxiliary liquid spraying. The Z-axis motor drives the sensor to rise in the vertical direction, and the Y-axis motor drives the workpiece to rotate forward synchronously to spray quenching liquid. After the quenching of the first tooth is completed, the sensor Stop heating, stop spraying quenching liquid;
[0014] B. Processing the nth tooth: the Y-axis motor drives the workpiece to rotate to ×n, the X-axis motor drives the worktable to move in the horizontal direction, and the Z-axis motor drives the worktable to move in the vertical directi...

The invention discloses a method for single tooth quenching of a gear and scale division according to teeth. The method is implemented according to the following steps that: A. the first tooth is processed as follows: a sensor is used for heating and assists the liquid spraying, a Z-axis motor drives a the sensor to ascend along the vertical direction, a Y-axis motor drives a workpiece to synchronously rotate in the forward direction, and spray quenching bath, so that the first tooth is processed; B. the nth tooth is processed as follows: the Y-axis motor drives the workpiece to arrive the position 360*M*n / N, so that the sensor moves to the bottom of the tooth to be processed, then the sensor starts to heat and assists the liquid spraying, a Z-axis motor drives the sensor to ascend along the vertical direction, the Y-axis motor drives the workpiece to rotate synchronously and spray the quenching liquid so as to complete the quenching of the nth tooth, and the steps are repeated until the first round of quenching is completed; and C. repeating the step B. According to the invention, the workpiece does not need to be corrected repeatedly in the processing process, the work efficiency is improved, and the quenching quality is ensured.
Description
technical field [0001] The invention belongs to a method for processing gears, in particular to a single tooth quenching method for large gears. Background technique [0002] In the field of induction heating, when large-scale special gears (straight teeth, helical gears, bevel gears, etc.) are single-tooth scanned and quenched, three-coordinate drive is usually used, and the X-axis is the horizontal feed axis, which drives the quenching transformer to move left and right to adapt to different sizes. Gear quenching; Y-axis is the rotating indexing axis, which turns the gear to the quenching position; Z-axis is the lifting axis, which drives the sensor (coil) to the quenching position. In the gear indexing, the general numerical control system usually adopts the indexing by angle. The method is: set the number of gear teeth as N, and each indexing M teeth (incremental given), then the indexing angle is Spend. In this way, the following two situations will occur: 1. For mos...
