[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] like Figure 1 As shown;

[0041] An irregular stepped short shaft feeding mechanism for assembling a gearbox comprises a machine base 1, a connecting seat 2 is arranged on the top surface of the machine base 1, a feeding component 3 is fixedly arranged on the top surface of the connecting seat 2, a feeding component 4 is penetrated through one side of the feeding component 3, a posture adjustment component 5 is fixedly connected to the side of the feeding component 3 away from the feeding component 4, and a clamping conveyor belt 6 is connected to one end of the posture adjustment component 5.

[0042] In the present embodiment: the irregular short shaft located in the material box 31 is always pushed by the feeding component 4 to move toward the upper material end, and then the irregular short shaft in the material box 31 can be transported to the posture adjustment component 5 through the loading component 3, and the posture of the irregular short shaft is automatically adjusted to the posture required by the installation station, and transported to the assembly station through the clamping conveyor belt 6, and then through this mechanism, the irregular short shaft in the material box 31 can be conveniently and quickly transported to the assembly installation station, and in this process, the posture of the irregular short shaft can be automatically adjusted, which is convenient for the subsequent station to take, thereby improving the efficiency of feeding irregular stepped short shafts for gearbox assembly, and at the same time has the characteristics of reasonable structural design, convenience and practicality.

[0043] It should be noted that the clamping conveyor belt 6 is two symmetrically arranged vertical conveyor belts, and the distance between the two conveyor belts is consistent with the bottom outer diameter of the irregular short shaft, thereby facilitating its transportation.

[0044] like Figure 2 and Figure 3 and Figure 5 As shown;

[0045] In an optional embodiment: the feeding assembly 3 includes a material box 31, a three-axis cylinder 32, a lifting plate 33, a feeding plate 1 34, a feeding plate 2 35 and a limit piece 36, the material box 31 is fixedly connected to the top of the connecting seat 2, a feeding assembly 4 is penetrated on one side of the material box 31, the three-axis cylinder 32 is fixedly connected to the machine base 1 through a fixed mounting plate, a lifting plate 33 is fixedly provided on the top of the piston of the three-axis cylinder 32, a feeding plate 1 34 and a feeding plate 2 35 are symmetrically provided on the top of the lifting plate 33, and the feeding plate 1 34 penetrates the material box 31 and extends to the inside of the material box 31, the feeding plate 2 35 is located on the outer wall of the material box 31 and slidably cooperates with the outer wall of the material box 31, and a plurality of limit pieces 36 for buffering are fixedly provided on the bottom end surface of the material box 31.

[0046] It should be noted that the angles between the inclination surface 341, the outclination surface 342 and the bottom end surface of the loading plate 1 34 are all acute angles, and the inclination directions of the inclination surface 341 and the outclination surface 342 are opposite. The top of the loading plate 2 35 is provided with an inclined surface 1 351, and the inclination angle and inclination direction of the inclined surface 1 351 are consistent with those of the outclination surface 342. The height of the loading plate 2 35 is greater than the height of the loading plate 1 34.

[0047] In this embodiment, by starting the three-axis cylinder 32, the lifting plate 33 is driven to lift, and the loading plate 1 34 and the loading plate 2 35 are driven to lift at the same time. Due to the acute angle between the outer inclined surface 342 and the inner wall of the material box 31, the two irregular shafts can be driven to lift. When the bottom end of the top inclined surface of the loading plate 1 34 is flush with the top of the inclined surface of the side wall of the material box 31, under the action of gravity, the two irregular short shafts roll down to the side wall of the material box 31 and the loading plate 2 35. At the angle between them, since the height of the second loading plate 35 is greater than the height of the first loading plate 34, the irregular short shaft can stay stably on the top of the side wall of the material box 31, and then when the three-axis cylinder 32 retracts, it drives the lifting plate 33 to fall back, and when the top of the inclined surface of the second loading plate 35 is flush with the bottom of the inclined surface of the side wall of the material box 31, under the action of gravity, the irregular short shaft slides along the inclined surface and falls into the posture adjustment component 5, completing the loading operation from the material box 31 to the posture adjustment component 5.

[0048] It should be understood that the maximum stroke of the three-axis cylinder 32 is consistent with the height of the loading plate 34, an inclination surface 341 is arranged in the middle position of the top of the loading plate 34, and outclination surfaces 342 are symmetrically arranged on both sides of the inclination surface 341, and the lengths of the inclination surface 341 and the outclination surface 342 are consistent. By setting the inclination surface 341 in the middle position of the top of the loading plate 34, and the inclination direction of the inclination surface 341 is opposite to the inclination direction of the outclination surface 342, this makes it possible for one side of the loading plate 34 to lift at most two irregular short shafts, and there is a certain distance between the two irregular short shafts. This distance is the space reserved for the subsequent rolling adjustment of the irregular short shaft posture, thereby ensuring the efficiency of the subsequent posture adjustment.

[0049] like Figure 1 and Figure 2 and Figure 6 As shown;

[0050] In an optional embodiment: the posture adjustment component 5 includes a connecting plate 51, a shaping plate 52, an end plate 53, a slide rail 54, a guide rod 55, a slide seat 56, a transmission member 57 and a pen-shaped cylinder 58. The side of the material box 31 away from the feeding component 4 is fixedly connected with the connecting plate 51, and the shaping plate 52 is symmetrically arranged on one side of the connecting plate 51. The bottom of the two shaping plates 52 away from the connecting plate 51 is fixedly connected with the end plate 53, and the top of the end plate 53 facing the connecting plate 51 is fixedly connected with the guide rod 55. The middle part of the end plate 53 and below the guide rod 55 is provided with a slide rail 54, and the slide The other ends of the rail 54 and the guide rod 55 are fixedly connected to the bottom of the connecting plate 51, the top of the slide rail 54 is slidably connected to the slide seat 56, and the guide rod 55 passes through the top of the slide seat 56 and is slidably connected to the slide seat 56. One side of the connecting plate 51 is connected to a pen-shaped cylinder 58 through a fixed plate, and the piston rod of the pen-shaped cylinder 58 is fixedly connected to a transmission member 57, and the other end of the transmission member 57 is fixedly connected to the side wall of the slide seat 56. The two shaping plates 52 have the same structure, and the top of the shaping plate 52 is provided with an inclined surface two, and the distance between the two inclined surfaces two and the two shaping plates 52 constitutes a Y-shaped cavity 522.

[0051] It should be noted that the slide 56 includes a special-shaped slider 561 , a guide block 562 and a lever 563 . The guide block 562 is fixedly provided at the top of the special-shaped slider 561 , and the lever 563 is fixedly provided at the middle position of the top surface of the guide block 562 .

[0052] In this embodiment: when the irregular short shaft falls into the Y-shaped cavity 522, due to the characteristics of the irregular short shaft's own structure, its center of gravity is located at the top, and then under the action of gravity and the two inclined surfaces 2, the top large diameter section of the irregular short shaft contacts the inclined surface 2, and the bottom slides along the inclined surface 2 to the Y-shaped cavity 522, completing the posture adjustment, and then the pen-shaped cylinder 58 is started to drive the slide 56 along the slide rail 54 and move under the guidance of the guide rod 55. At this time, the slide 56 drives the lever 563 to move in the Y-shaped cavity 522, so that the lever 563 pushes the irregular short shaft to move until it contacts the clamping conveyor belt 6 and is transported to the assembly station.

[0053] like Figure 2 As shown;

[0054] In an optional embodiment: the feed assembly 4 includes a casing 41, a wedge block 42, a step guide column 43, a spring 44 and an end cover 45, the casing 41 is fixedly arranged on the top surface of the connecting seat 2, a plurality of step guide columns 43 are slidably connected inside the casing 41, and one end of the step guide column 43 located inside the material box 31 is fixedly connected to the wedge block 42, and the bottom of the wedge block 42 is slidably connected to the bottom plate of the material box 31 through a slide groove, the end of the casing 41 away from the material box 31 is fixedly connected to the end cover 45, and the step guide column 43 passes through the end cover 45 and extends to the outside of the end cover 45, a spring 44 is fixedly arranged between the hanging platform of the step guide column 43 and the end cover 45, and the inclination angle of the inclined surface of the wedge block 42 is greater than the inclination angle of the side wall of the material box 31.

[0055] In this embodiment: under the action of the elastic force of the spring 44, the stepped guide column 43 has a tendency to always move toward the material box 31, thereby driving the wedge block 42 to move along the slide groove, so that the wedge block 42 always squeezes the irregular short axis located in the material box 31 to ensure the loading efficiency of the loading component 3.

[0056] It should be noted that the number of the step guide pillars 43 is at least two, so as to form a limit between the step guide pillars 43 and the wedge block 42, ensuring that the step guide pillars 43 will not rotate when moving, and the wedge block 42 will move more smoothly and accurately without getting stuck.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
