The counter cone assembly machine of claim 1, wherein: the cone set placing station and the cone shaft penetrating station are respectively provided with a cone temporary storage bin (740) and a cone shaft temporary storage bin (750), the cone temporary storage bin (740) and the cone shaft temporary storage bin (750) are arranged side by side, and the cone set placing station and the cone shaft penetrating station are provided with a cone pushing mechanism (741) and a cone feeding mechanism (742) which are arranged corresponding to the cone temporary storage bin (740), and a cone shaft pushing mechanism (751) and a cone shaft feeding mechanism (752) which are arranged corresponding to the cone shaft temporary storage bin (750);

the cross section of the cone temporary storage bin (740) is adapted to a cone, the cone shaft temporary storage bin (750) comprises a storage hopper (753), a leveling channel (754) and a material waiting tank (755) which are sequentially arranged from top to bottom, wherein the leveling channel (754) is in a regular chord wave shape, and two ends of the material waiting tank (755) are open.

9. A method of assembling a counter cone assembly using the counter cone assembly machine of any one of claims 1-8, comprising the steps of:

s1, starting a machine, and respectively supplying a preset number of cones and bearing pins to the cone temporary storage bin (740) and the bearing pin temporary storage bin (750);

s2, the combined die (710) is initially opposite to the roller cone temporary storage bin (740), the roller cone pushing mechanism (741) is started, a preset number of roller cones are pushed into the combined groove (711), and pre-clamping is carried out through the side die block (713);

s3, the combined die (710) is moved to a position opposite to the cone shaft temporary storage bin (750) through the driving mechanism (720), the cone shaft pushing mechanism (751) is started, and the cone shaft is pushed out to penetrate all cones in the combined groove (711) to form a finished cone assembly;

s4, placing the counter with the character wheel assembly on a carrier (910), enabling the opening of a cone pulley shaft clamping groove in the counter to be vertically upward, starting a transfer mechanism (730), grabbing the finished cone pulley assembly to be right above the character pulley shaft clamping groove through a finger grabbing clamp (735), and moving downwards to enable two ends of the cone pulley shaft to be clamped into the corresponding cone pulley shaft clamping grooves;

s5, resetting the transfer mechanism (730), starting the code arranging assembly (800), arranging the character wheels on the counter, and ensuring that the characters on all the character wheels are aligned one by one to finish the assembly.
