The rough machining process for sprockets specifically includes blank selection, turning, drilling (drilling the mounting hole in the sprocket center), milling the tooth profile, and deburring. For example, in mass production of sprockets, round steel blanks of appropriate size are first selected.

[0031] Example 1
[0032] like Figure 1-4 As shown, a sprocket rough processing device proposed by the present invention includes a processing table 1, a drilling mechanism 3 for drilling holes in the sprocket is arranged above the processing table 1, a clamping mechanism 5 located below the drilling mechanism 3 is installed on the processing table 1, and the clamping mechanism 5 includes a predecessor of the sprocket: a placement plate 51 of a disc, and two sets of relatively arranged movable arc plates 58 are arranged on the top of the placement plate 51. The inner arc surfaces of the two movable arc plates 58 and the bottom of the lower pressure plate 64 are provided with protective blocks for ensuring high friction of the collision, which are not shown in the figure; a lower pressure mechanism 6 is installed on the top of the two movable arc plates 58, and the lower pressure mechanism 6 includes a plurality of movable arc plates 58, each comprising ... The lower pressing plate 64 is installed on one side of the movable arc plate 58, and the lower pressing mechanism 6 also includes a threaded column 61 that is rotatably installed in the threaded hole 582. The bottom of the threaded column 61 is fixedly connected to a lifting block 62, and the bottom of the lifting block 62 is fixedly connected to a spring 63. The lifting block 62 is slidingly arranged in the lifting groove 581, and the bottom end of the threaded column 61 is rotatably arranged with the top of the lifting block 62. One side of the lifting block 62 is fixedly connected to the lower pressing plate 64. The height of the lifting block 62 in the lifting groove 581 is adjusted by rotating the threaded column 61, thereby adjusting the height of the lower pressing plate 64 connected to one side of the lifting block 62.
[0033] like Figure 3 and Figure 4As shown, a driving motor 53 is provided at the bottom of the placement plate 51, and a fixing seat 52 is fixedly connected to the bottom of the placement plate 51. The fixing seat 52 is fixedly connected to the top of the processing table 1, and the driving motor 53 is connected to the upper surface of the processing table 1. The outer ring of the output end of the driving motor 53 is fixedly sleeved with a gear plate 54. Racks 55 are provided on both sides of the gear plate 54 for meshing transmission. There are at least two groups of racks 55. Rectangular sliding holes are provided in both groups of racks 55. A rectangular rod 56 is slidably installed on the inner wall of the rectangular sliding hole. One end of the rectangular rod 56 is connected to a fixed block. The fixed block is connected to the placement plate 51. The bottom is fixedly connected, and the rectangular rod 56 is provided to guide the movement of the rack 55, so that the two racks 55 can move relatively stably. The tops of the two sets of racks 55 are provided with guide rods 57 fixedly connected to the bottom of the movable arc plate 58. Two guide holes 501 are provided on the placement plate 51.

[0034] The two gears 55 are meshed and driven by the racks 55 on both sides of the gear plate 54. The two racks 55 are guided relative to each other through the guidance of the rectangular rod 56, so that the two guide rods 57 slide along the inner wall of the guide hole 501, so that the movable arc plate 58 connected to the top of the guide rod 57 moves relatively close to each other, firmly clamping the outer periphery of the disc, and rotating the two threaded columns 61. The downward rotation of the threaded column 61 pushes the lifting block 62 to slide along the inner wall of the lifting groove 581, thereby moving the lower pressure plate 64 connected to one side of the lifting block 62 downward. The downward pressure of the lower pressure plate 64 limits the upper and lower positions of the disc on the placement disc 51, thereby clamping the upper and lower positions of the disc. Combined with the drilling of the drilling mechanism 3, the drilling processing of the disc is realized. At this time, the disc will not slide or deflect, and the drilling processing is more accurate.
