[0036] The present invention also includes a high-efficiency edge grinding device for precision gear machining, and the operation method is as follows:

[0037] S1. First, the inner ring of the gear is placed on the outer side of the clamping plate 103 and supported by the pad 104. The output end of the electric push rod 107 is controlled by the control panel 12 to drive the pressure sensor 108 and the top head 109 to rise, so that the top head 109 contacts the adapter groove 105, and the clamping plate 103 is pressed outward along the moving groove, so that the connecting spring 106 is compressed, and then the clamping plate 103 clamps the inner ring of the gear.

[0039] S3. Finally, the output end of the lifting cylinder 5 drives the first connecting frame 6 and the first connecting seat 7 to descend along the through hole, and at the same time, the output end of the edge grinding motor 8 drives the edge grinder 9 to rotate until the edge grinder 9 grinds the outer side of the gear. At the same time, under the support of the second connecting frame 111, the output end of the rotating motor 112 drives the electric push rod 107 to rotate, and further drives the second connecting seat 102 to rotate along the inside of the rotating groove 113, and the limiting ring 114 to rotate along the inside of the limiting groove 115, thereby rotating the gear, which is convenient for uniform edge grinding of the outer side of the gear.

[0040] The working principle of the present invention is as follows: during the use of the edge grinding device, the gear is clamped by the clamping assembly 10, the movement of the support frame 2 is controlled by the moving assembly 3, the output end of the lifting cylinder 5 is controlled by the control panel 12 to drive the first connecting frame 6 and the first connecting seat 7 to descend, the edge grinding motor 8 is started to drive the edge grinder 9 to grind the gear, and at the same time, the control panel 12 controls the rotating assembly 11 to drive the clamping assembly 10 and the gear to rotate, so that the outer side of the gear is evenly ground.

[0041] It should be noted that, through the setting of the moving component 3, when the support frame 2 and the edge grinder 9 need to be moved, the control panel 12 is used to control the moving distance of the support frame 2, and the output end of the electric telescopic rod 36 is controlled to drive the slider 32 to move along the inside of the slide groove 31, and at the same time drive the guide hole 35 to slide along the outside of the guide rod 34.

[0042] It should be noted that through the setting of the clamping assembly 10, when clamping the gear, the output end of the electric push rod 107 is controlled by the control panel 12 to drive the pressure sensor 108 and the top head 109 to rise, so that the top head 109 contacts the adapter groove 105, and the clamping plate 103 is squeezed outward along the moving groove, so that the connecting spring 106 is compressed, and then the clamping plate 103 clamps the inner ring of the gear. At this time, the output end of the electric push rod 107 continues to operate, and the rising pressure of the top head 109 is detected by the pressure sensor 108. After reaching the set interval value, it is fed back to the control circuit board, thereby stopping the operation of the output end of the electric push rod 107, and automatically clamping and fixing the gear.

[0043] It should be noted that through the setting of the rotating component 11, when the gear clamped by the clamping component 10 is rotated, under the support of the second connecting frame 111, the output end of the rotating motor 112 drives the electric push rod 107 to rotate, and further drives the second connecting seat 102 to rotate along the inside of the rotating groove 113, and the limiting ring 114 to rotate along the inside of the limiting groove 115, thereby rotating the gear, making it convenient to evenly grind the outer side of the gear.
