Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Example 1:

referring to fig. 1-3, the present invention provides a technical solution: a rapid positioning device for grinding teeth for an idler shaft comprises a bottom plate 1, wherein an inner embedded groove 11 is formed in the middle of the top surface of the bottom plate 1 in a penetrating mode; the top surface of the bottom plate 1 positioned at one end of the embedded groove 11 is fixedly connected with one end of a vertical bar I3, the inner wall of one end of the embedded groove 11 is fixedly connected with the bottom end of an electric push rod 2, the telescopic end of the electric push rod 2 is fixedly connected with one side wall of a sliding block 62, and the top wall of the sliding block 62 is fixedly connected with the bottom wall of a vertical bar II 6;

a clamping groove 31 is formed in the side walls of the first vertical bar 3 and the second vertical bar 6 in a penetrating mode, a clamping block 51 is movably clamped in the clamping groove 31, and the other side wall of the clamping block 51 is fixedly connected to the outer side wall of the collecting box 5.

A clamping groove 31 is formed in one side wall of each of the first vertical bar 3 and the second vertical bar 6, a clamping block 51 is clamped in the clamping groove 31, the clamping block 51 is fixedly connected to the outer side wall of the collection box 5, meanwhile, the collection box 5 is located below the threaded shaft 41, when external grinding equipment carries out tooth grinding operation on the idler wheel part 8, dropped debris drops into the collection box 5, and unified collection can be carried out on the debris;

a fixing block 7 is fixedly embedded in one third of the vertical bar II 6, a circular through groove is transversely formed in the fixing block 7 in a penetrating mode, one end of a spring 72 is fixedly connected to the inner wall of the through groove, and the other end of the spring 72 is fixedly connected to the outer ring wall of the annular sheet 71. The motor 4 is fixedly arranged at one third of the first vertical bar 3 in a penetrating way, one end of the motor 4 is fixedly connected with a threaded shaft 41, and the other end of the threaded shaft 41 is rotatably connected between the opposite annular sheets 71.

Example 2:

a fixed bolt 42 is fixedly sleeved on the threaded shaft 41 arranged between the vertical bar I3 and the vertical bar II 6, an idler wheel piece 8 is movably sleeved on the threaded shaft 41 beside the fixed bolt 42, and a movable bolt 44 is movably sleeved on the threaded shaft 41 beside the idler wheel piece 8. Idler member 8 is in close contact with one side wall to which fixed bolt 42 is attached, idler member 8 is in close contact with the other side wall to which movable bolt 44 is attached,

the height of the first vertical bar 3 is greater than that of the second vertical bar 6, and the collecting box 5 is positioned right below the threaded shaft 41. The threaded shaft 41 at one end of the motor 4 is different from the lead screw; the outer rings of the two ends of the threaded shaft 41 are not provided with threads until the threads are arranged at the middle section of the threaded shaft 41, the length of the threaded shaft 41 is smaller than that of the embedded groove 11, the length of the collecting box 5 is the same as that of the threaded shaft 41, and the direction in which the motor 4 drives the threaded shaft 41 to rotate is opposite to the direction in which the movable bolt 44 is rotatably sleeved on the threaded shaft 41.
