[0047] The grinding arc plate 618 at the outer end of the gear shaft 4 is wrapped around the two ends of the gear shaft 4.

[0048] like Figure 10-12 As shown, as a preferred embodiment, on the basis of the above-mentioned method, it further includes: a gear grinding mechanism 7, which is used to cooperate with the shaft grinding mechanism 6 to grind the gear synchronously, and the gear grinding mechanism 7 includes two groups of gear grinding plates 71 and two groups of fixed shafts 72 located in the arc groove 9, and the lower ends of the two groups of gear grinding plates 71 are provided with a positioning seat 73, the outer end of the positioning seat 73 is provided with a first rotating rod 74, the upper end of the first rotating rod 74 is provided with a second rotating rod 75, the two ends of the first rotating rod 74 are provided with embedded grooves 78, the inner end of the embedded groove 78 is provided with a second spring 710, the center of the second rotating rod 75 is provided with a hollow groove 76, the inner end of the hollow groove 76 is provided with a central rod 77, and the outer end of the central rod 77 is provided with a first spring 79.

[0050] The inner ends of the two groups of first rotating rods 74 are movably connected to the second rotating rod 75, and the embedded groove 78 passes through the inner surfaces of the front and rear ends of the first rotating rod 74. The inner ends of the embedded groove 78 are movably connected to the second spring 710. The first rotating rod 74 and the second rotating rod 75 are slidingly connected.

The upper end of the central rod 77 is fixedly connected to the arc groove 9, and the first spring 79 is wrapped around the outer end of the central rod 77.

[0051] The telescopic cylinder 10 drives the arc disk 8 to move to the upper end of the gear shaft 4. At this time, through the rotation of the gear grinding plate 71 along the fixed shaft 72, according to the tooth profile size of the different gear shafts 4, the first rotating rod 74 and the second rotating rod 75 connected by the positioning seat 73 change the size of the angle between the two sets of gear grinding plates 71, and the first spring 79 and the second spring 710 can ensure that after each gear grinding is completed, it can return to its original state.

[0052] like Figure 2As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a rotating mechanism 5 is used to link the gear shaft 4 movable in the grinder 1, the feed belt 2 and the discharge belt 3, and the rotating mechanism 5 includes a turntable 51 located between the feed belt 2 and the discharge belt 3, a positioning shaft 53 is provided at the inner end of the turntable 51, a linkage plate 54 is provided at the outer end of the positioning shaft 53, a rotating hook 52 is provided at the outer end of the linkage plate 54, a power shaft 55 is provided in the center of the turntable 51, and a linkage belt 56 is provided at the outer end of the power shaft 55.

[0053] The inner end of the turntable 51 is fixedly connected to the positioning shaft 53. The number of the positioning shafts 53 is set to three groups. The three groups of positioning shafts 53 are arranged in a circular array along the periphery of the turntable 51. The outer end of the positioning shaft 53 is movably connected to the linkage plate 54. The outer end of the linkage plate 54 is fixedly connected to the rotating hook 52. The center of the turntable 51 is fixedly connected to the power shaft 55. The outer end of the power shaft 55 is movably connected to the motor through a linkage belt 56. The movable end of the feed belt 2 is movably connected to the linkage belt 56.

[0054] The power shaft 55 is driven by the motor to rotate, promoting the synchronous rotation of the feed belt 2 and the turntable 51. During the rotation of the three groups of rotating spoons outside the turntable 51, when passing the lower end of the feed belt 2, the gear shaft 4 falls on the corresponding rotating spoons. The rotating spoons are driven by the turntable 51 to move to the center of the shaft grinding mechanism 6, and the connecting cylinder drives the outer positioning cylinder 611 connected to the linkage motor 610 to move forward, so that the corresponding positioning suction cups 61 outside the retraction rod 62 are adsorbed on the two end sides of the gear shaft 4.

[0055] After grinding is completed, the corresponding rotating mechanism 5 drives the ground gear shaft 4 to rotate and move to the discharge belt 3. In this process, the rotating hook 52 at the lower end grabs the gear shaft 4 to be ground, and the grabbed rotating hook 52 is interconnected with the shaft grinding mechanism 6 and the gear grinding mechanism 7. Grinding here realizes the cycle and accelerates the grinding process.

[0056] When the present application is in use: the gear shaft 4 to be ground is placed equidistantly on the feed belt 2, and the power shaft 55 of the rotating mechanism 5 is driven by the motor to rotate, which promotes the synchronous rotation of the feed belt 2 and the turntable 51. During the rotation process, the three groups of rotating spoons outside the turntable 51 pass through the lower end of the feed belt 2, and the gear shaft 4 falls on the corresponding rotating spoon. The rotating spoon is driven by the turntable 51 to move to the center of the shaft grinding mechanism 6, and the connecting cylinder drives the outer positioning cylinder 611 connected to the linkage motor 610 to move forward, so that the corresponding positioning suction cup 61 outside the retracting rod 62 is adsorbed on both ends of the gear shaft 4. From the side, at this time, the grinding arc plate 618 at the outer end of the gear shaft 4 is wrapped around the two ends of the gear shaft 4, and the linkage motor 610 is started to drive the gear shaft 4 to rotate, so that the axial surface of the outer end of the gear shaft 4 and the grinding arc plate 618 can contact each other, and the axial surface grinding of the gear shaft 4 is realized. The axial surfaces of many existing gear shafts 4 are provided with a number of layers, and the axial surface radius increases layer by layer. Then, the linkage motor 610 can be pushed to move in the outer positioning cylinder 611 by connecting the cylinder, and the grinding arc plate 618 connected by the hole groove 615 at the tail end of the linkage motor 610 can be expanded, which can facilitate the grinding of multiple groups of different axial surface diameters;

[0057] At the same time, in the process of grinding the shaft surface, the tooth surface of the gear shaft 4 can be contacted with each other through the tooth grinding mechanism 7 (the contact of the tooth surface is driven by the telescopic cylinder 10 to move the arc plate 8 to the upper end of the gear shaft 4. At this time, the tooth grinding plate 71 rotates along the fixed shaft 72. According to the tooth profile size of the different gear shafts 4, the first rotating rod 74 and the second rotating rod 75 connected by the positioning seat 73 change the size of the angle between the two sets of tooth grinding plates 71, and the first spring 79 and the second spring 710 can ensure that each time the gear is ground, it can return to the original state). In the process of the positioning suction cup 61 driving the gear shaft 4 to be ground to rotate, the tooth grinding mechanism 7 moves along the gear surface, realizing synchronous grinding, avoiding the non-standard size of the gear shaft 4 caused by inconsistent grinding of the shaft surface and the tooth surface, and increasing the number of grinding times;

[0058] After grinding is completed, the corresponding rotating mechanism 5 drives the ground gear shaft 4 to rotate and move to the discharge belt 3. In this process, the rotating hook 52 at the lower end grabs the gear shaft 4 to be ground, and the grabbed rotating hook 52 is interconnected with the shaft grinding mechanism 6 and the gear grinding mechanism 7. Grinding here realizes the cycle and accelerates the grinding process.

[0059] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods.
