Detailed Description

The present invention will be described in further detail with reference to the following examples, which are illustrative of the present invention and are not intended to limit the present invention.

Example 1:

as shown in fig. 1 and 2, the winding mechanism for the in-slot winding machine according to the present embodiment includes a frame 1, a motor 2, a spindle 3, a cam box 4, and a spline shaft 5; the cam box 4 comprises a power input shaft 41 and a power output shaft 42, the transmission structure of the cam box 4 in the embodiment is the prior art, and is a structure in the prior art that a cam rotates to drive a driven wheel to swing, specifically, the power input shaft 41 of the cam box 4 rotates by 0-35 degrees to drive the power output shaft 42, and the power output shaft 42 is not moved when the power input shaft 41 rotates by 35-90 degrees; when the power input shaft 41 rotates by 90-125 degrees, the power output shaft 42 is driven, and when the power input shaft 41 rotates by 125-180 degrees, the power output shaft 42 is not moved; and the process is circulated. In the embodiment, the motor 2 drives the spindle 3 to rotate, and the spindle 3 rotates around the central axis thereof; the main shaft 3 is in transmission connection with a power input shaft 41 of the cam box 4, specifically, synchronous belt transmission or gear or chain transmission can be adopted, a power output shaft 42 of the cam box 4 drives a spline shaft 5 to swing, the spline shaft 5 is connected with the frame 1 in a sliding mode, the spline shaft 5 can rotate around the axis of the spline shaft, the spline shaft 5 is connected with a sliding block 6, the sliding block 6 and the spline shaft 5 are arranged in a circumferential rotating and axial fixing mode, one end of a connecting rod 9 deviates from the central axis of the main shaft 3 and is connected with the main shaft 3 in a rotating mode, and the other end; the spline shaft 5 is of a hollow structure, a wire nozzle 7 is arranged at the upper end of the spline shaft 5, and an enameled wire 8 is arranged in the spline shaft 5 and extends out of the wire nozzle 7; the input-output transmission ratio of the cam box 4 is 1:2, namely the power input shaft 41 rotates 360 degrees, and the power output shaft 42 swings for 2 times; the rotation ratio of the main shaft 3 to the power input shaft 41 is 2:1, namely, the main shaft 3 rotates 2 circles, and the power input shaft 41 rotates 1 circle.
