[0016] A process according to the above-mentioned high wear-resistant gear processing equipment comprises the following steps:

[0017] Step 1: Cleaning, start the gear hobbing and the support seat to rotate, and the rotating gear hobbing will cut the side surface of the gear to be processed into teeth. The rotation of the support seat will drive the transmission gear to rotate through the transmission gear block, and the rotation of the transmission gear will drive the rotating rod to rotate through the belt. Since the rotating rod is in a 'Z' shape, the rotation of the rotating rod will drive the movable collar to make a circular motion with the turning point of the rotating rod as the axis. Since the movable collar is movably clamped on the outer surface of the swing rod, and the radius of the movable collar to make a circular motion is small, when the movable collar rotates in the first and second quadrants, it will drive the swing rod to rotate around the first rotation axis toward the gear to be processed. When the movable collar rotates in the fourth and third quadrants, it will drive the swing rod to rotate around the first rotation axis away from the gear to be processed. When the swing rod swings left and right, the brush on the swing rod will clean the debris on the surface of the gear to be processed to prevent interference with the quality inspection of the gear.

[0018] Step 2: Positioning. When the swing arm swings left and right, it will drive the sleeve to move in the positioning groove. When the swing arm rotates toward the gear to be processed, the positioning rod on the side surface of the sleeve moves in the inner groove above the positioning groove. When the positioning rod is located in the inner groove above the positioning groove, the brush fixed on the side surface of the sleeve will not contact the gear to be processed. When the swing arm swings to the maximum angle, the positioning rod is located at the connection between the upper and lower inner grooves on the far right of the positioning groove. Due to the elasticity of the first spring, the first spring will squeeze the sleeve downward to make the positioning rod slide to the inner groove below the positioning groove. At this time, the brush will contact the gear to be processed, and the swing arm will rotate away from the gear to be processed. There is a horizontal section in the inner groove below the positioning groove on the right side, and its length is equal to the radius of the gear to be processed. When the positioning rod is located in this horizontal inner groove, the brush will The debris is cleaned to make the debris on its surface fall off. The continued rotation of the swing arm will drive the positioning rod to gradually lift upward in the inner groove below the positioning groove and knock open the obstruction of the limit block and lift it to the connecting part of the upper and lower inner grooves of the leftmost positioning groove. Subsequently, the elasticity of the second spring drives the limit block to reset. Since the movable plate and the second limit plate are directly contacted by the second spring, the limit block under the limit of the second limit plate can only rotate clockwise but not counterclockwise. Therefore, when the positioning rod moves from the connecting part of the upper and lower inner grooves of the leftmost positioning groove to the upper inner groove of the right positioning groove, it will be supported by the limit block, thereby realizing the circular movement of the positioning rod in the positioning groove, and the brush will only clean the gear to be processed from the inside to the outside, and will not clean the debris to other parts of the upper surface of the gear to be processed, thereby cleaning the debris accumulated on the surface of the gear to be processed.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] Start the gear hobbing and support seat to rotate, and the rotating gear hobbing will cut the side surface of the gear to be processed into teeth. The rotation of the support seat will drive the transmission gear to rotate through the transmission gear block, and the rotation of the transmission gear will drive the rotating rod to rotate through the belt. Since the rotating rod is in a 'Z' shape, the rotation of the rotating rod will drive the movable collar to make a circular motion with the turning point of the rotating rod as the axis. Since the movable collar is movably clamped on the outer surface of the swing rod, and the radius of the movable collar for the circular motion is small, when the movable collar rotates and is located in the first and second quadrants, it will drive the swing rod to rotate around the first rotation axis toward the gear to be processed. When the movable collar rotates and is located in the fourth and third quadrants, it will drive the swing rod to rotate around the first rotation axis away from the gear to be processed. When the swing rod swings left and right, the brush on the swing rod will clean the debris on the surface of the gear to be processed to prevent interference with the quality inspection of the gear.

Then, due to the elasticity of the second spring (33), the limit block (31) is driven to reset. Since the movable plate (34) and the second limit plate (37) are squeezed and directly contacted by the second spring (33), the lower limit of the second limit plate (37) is The positioning block (31) can only rotate clockwise but not counterclockwise. Therefore, when the positioning rod (24) moves from the connecting point of the upper and lower inner grooves of the leftmost positioning groove (30) to the upper inner groove of the right positioning groove (30), it will be supported by the limiting block (31), thereby realizing the circular movement of the positioning rod (24) in the positioning groove (30). The brush (27) will only clean the gear (3) to be processed from the inside to the outside, and will not clean the debris to other parts of the upper surface of the gear (3) to be processed, so that the debris accumulated on the surface of the gear (3) to be processed can be cleaned.
