The working principle is as follows:
step one, superposing gears which are required to be assembled in a gear box according to the same diameter, and then placing the gears in a corresponding blanking structure 5; the second electric slide rail 531 in the blanking unit 53 is controlled to drive the lifting rods 532 to drive the pallet 533 to be separated relatively, namely, gears which are stacked and placed can be put into the pallet 533, and the relative distance between the gears with different diameters to be put into the pallet 533 can be adjusted;
step two, when gears with different diameters are put into, a third electric sliding rail 534 is required to be driven, the distance between the side baffles 5355 in the gear assembly 535 is adjusted, and along with the corresponding adjustment between the container racks 533 according to the adjustment of the diameters of the gears, namely, the container racks 533 are used for limiting and bearing the bottoms at the left side and the right side, and the side baffles 5355 are positioned at the front side and the rear side of the push-out port for auxiliary limiting and shielding;
meanwhile, the diameters of the gears are different, the thicknesses of the gears are also changed, so that the gears with different thicknesses are required to be discharged from the pushing-out openings at the front sides between the container racks 533, in the pushing-out process of the gears at the bottommost part, the second gear and the third gear are required to be synchronously moved out due to friction stress, the second gear and the third gear are required to be shielded, the adjusting screw 5352 is required to be rotated, the adjusting screw 5352 can be rotated in the adjusting rack 5351 due to the installation and the limitation of the assembling screw 5353, and the adjusting screw 5352 is kept vertical due to the supporting stress of the adjusting seat 5354, so that the adjusting seat 5354 is stressed to be lifted by the rotation of the adjusting screw 5352 to drive the side baffle 5355 to adjust according to the thickness of the gears;
note that the side guards 5355 on the rear side of the pallet 533 are slightly lower than the side guards 5355 on the front side of the pallet 533 and higher than the push rod 625; the side baffle 5355 at the front side of the container 533 is required to be positioned above the upper wall of the bottommost gear, so that the bottommost gear cannot be shielded, the gear can be pushed out through the side baffle 5355, and a second or third gear can be shielded and limited at the same time, so that the gear is prevented from being moved out to drive the second gear;
step three, in the gear throwing process, the hydraulic cylinder 51 can be controlled to stretch to drive the plurality of blanking units 53 on the bracket 52 to rise firstly, then the gears which are overlapped and placed are placed above the conveyer belt units 2 according to a set throwing sequence, the gears need to be positioned below the corresponding container racks 533, then the blanking units 53 are controlled to descend and clamp by means of the relative movement of the container racks 533 after being regulated according to the diameters of the gears, the overlapped gears are directly thrown into storage (the operation needs to be carried out under the bottommost gears to apply cushion blocks smaller than the diameters of the gears to a certain extent, namely the bottoms can be directly clamped and carried), and then the blanking units 53 are controlled to be positioned at the corresponding heights of the conveyer belt units 2;
step four, after the gear is put in, according to the installation sequence of the gears, driving a pushing unit 62 corresponding to the blanking unit 53 in the pushing structure 6, driving a push rod 625 to move forwards by means of extension driving of an electric push rod 624, pushing out the corresponding gear at the bottommost, passing through a pushing outlet and a side baffle 5355, enabling the bottommost gear to move to the conveyor belt unit 2, and driving the conveyor belt unit 2 to move the gear leftwards to a position opposite to the mechanical arm 3 according to actual setting;
step five, during pushing out the bottommost gear by the push rod 625, the second gear loses the releasing force of the first gear and descends in turn to fall on the upper wall of the push rod 625, at this time, the second gear is positioned on the push rod 625 and above the bottom of the container 533, when the push rod 625 is reset and pulled away, the second gear replaces the original bottommost gear, further, the second gear can be used for discharging when the operation is performed again, and the discharging of other gears with different diameters is the same as the operation;
step six, the pushing unit 62 can move on the carriage 61 by means of the sleeve frame 621, and can perform transverse movement according to actual requirements, adjustment and correction alignment, and fastening by means of the mounting bolts 623; and the electric push rod 624 can be detached from the sleeve 622 through the detaching and installing bolt 623;
after the gears are fed and conveyed, the mechanical arm 3 drives the feeding structure 4 to move to align with the gears, and then the first electric sliding rail 42 is driven to drive the two corresponding groups of clamping units 43 to move relatively, so that the gears are clamped by the clamping rods 435; in the clamping process, because the diameters of the gears are different, the number of teeth on the outer sides of the gears is also different, and the clamping rod 435 cannot be ensured to be continuously positioned between the teeth of the gears for clamping and limiting;
step seven, however, the clamping rod 435 can swing back and forth for a certain angle in the swing box 432 by means of the second limit bolt 434, meanwhile, the clamping rod 435 can also bear force, and the clamping rod 435 can move in a forced way and be clamped between teeth by means of the limit of the swing box 432 in the first limit bolt 433 and swing left and right for a certain range in the swing frame 431;
the gear clamped by the mechanical arm 3 is carried and put into the corresponding part or the gear box for assembly, and in the assembly process, teeth of the gear cannot be completely meshed with the gear after being installed, so that the first motor 41 can be driven to drive the gear clamped to rotate and adjust to a certain extent, and the gear assembly is matched.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
