[0040] Referring to Figure 2 and Figure 7 , the long shaft feeding machine 4 comprises a long shaft storage bin 41 for long shaft storage, the bottom surface of the long shaft storage bin 41 is inclinedly arranged, the long shaft can roll to the lowest part of the bottom surface, the lowest part of the bottom surface of the long shaft storage bin 41 is provided with a long shaft discharging chute, the long shaft discharging chute is provided with a long shaft discharging plate 42, the lower part of the long shaft storage bin 41 is provided with a long shaft discharging cylinder 43 for pushing the long shaft discharging plate 42 to lift, the top of the long shaft discharging plate 42 is provided with a first long shaft V-shaped groove 44, one side of the long shaft storage bin 41 is provided with a long shaft feeding rack 45, the bottom of the long shaft feeding rack 45 is provided with a second long shaft V-shaped groove 46, and the end of the long shaft feeding rack 45 is provided with a long shaft feeding anti-falling piece 47.

[0041] The horizontal height of the long shaft feeding rack 45 is higher than the highest part of the side edge of the long shaft storage bin 41 and is flush with the top of the long shaft discharging plate 42 when the long shaft discharging plate 42 is ejected to the highest position, and the other side of the long shaft storage bin 41 is provided with a long shaft feeding cylinder 48 for pushing the long shaft from the long shaft discharging plate 42 into the long shaft feeding rack 45. The end of the long shaft feeding rack is provided with a long shaft clamping avoiding groove on both sides, and the long shaft clamping jaw cylinder 272 clamps the long shaft from the long shaft feeding rack after the long shaft is pushed into the long shaft feeding rack 45 from the long shaft discharging plate 42.

[0042] Referring to Figure 2 , Figure 5 and Figure 6 , the short shaft feeding machine 5 comprises a short shaft vibration disc 51, the output port of the short shaft vibration disc 51 is provided with a short shaft feeding rack 52, the short shaft feeding rack 52 is fixed on the supporting column of the conveying gantry 1, and a gap is left between the short shaft feeding rack 52 and the short shaft vibration disc 51 to avoid affecting the short shaft feeding rack 52 when the short shaft vibration disc 51 vibrates during screening, and the end of the short shaft feeding rack 52 is provided with a short shaft feeding anti-falling piece 53.

[0043] The bottom of the short shaft feeding rack 52 is provided with a first short shaft V-shaped groove 54, and the two sides of the end of the short shaft feeding rack 52 are provided with short shaft clamping avoidance grooves 55. The short shaft feeding rack 52 is provided with a supporting block 56 in the short shaft clamping avoidance groove 55. The supporting block 56 is provided with a second short shaft V-shaped groove 57. The two sides of the supporting block 56 are provided with side edge abutting blocks 58. The opposite wall surfaces of the side edge abutting blocks 58 are provided with abutting inclined surfaces.

[0044] The short shaft vibration disc 51 delivers the short shaft from the output port thereof into the short shaft feeding rack 52. The short shaft is blocked by the short shaft feeding anti-falling piece 53, thereby facilitating the short shaft clamping jaw cylinder 282 to clamp the short shaft through the short shaft clamping avoidance groove 55. Due to the arrangement of the short shaft clamping avoidance groove 55 and the short overall axial length of the short shaft, the arrangement of the supporting block 56 and the side edge abutting block 58 ensures that the end position of the short shaft does not deviate and the short shaft does not fall from the short shaft clamping avoidance groove 55, thereby improving the stability of the clamped short shaft.

[0045] It is worth noting that due to the arrangement of the side edge abutting block 58, in order not to affect the clamping of the short shaft by the short shaft clamping jaw cylinder 282, the short shaft clamping jaw cylinder 282 is provided with an avoidance slot 2857 on the short shaft clamping jaw 284.

[0046] Therefore, the long shaft clamping assembly 27 is used to clamp the long shaft in the long shaft feeding machine 4, the short shaft clamping assembly 28 is used to clamp the short shaft in the short shaft feeding machine 5, and the long shaft clamping assembly 27 and the short shaft clamping assembly 28 synchronously deliver the long shaft and the short shaft to the friction welding device 7 for friction welding.

[0047] In the present application, the long shaft driving part 276 and the short shaft driving part 285 are provided with a long shaft pushing spring 2766 and a short shaft pushing spring 2855, respectively. The spring force of the long shaft pushing spring 2766 is smaller than the clamping force of the long shaft clamping jaw cylinder 272 on the long shaft, and the spring force of the short shaft pushing spring 2855 is smaller than the clamping force of the short shaft clamping jaw cylinder 282 on the short shaft. Therefore, when the long shaft driving part 276 and the short shaft driving part 285 send the long shaft and the short shaft into the clamping jig of the friction welding device 7, respectively, the long shaft and the short shaft can be pushed into the predetermined position, and the clamping shallower or deeper situation can be avoided.

[0048] When the friction welding device 7 friction-welds the long shaft and the short shaft together, the finished product shaft clamping mechanism 3 clamps the finished product shaft out of the friction welding device 7 and delivers it to the finished product shaft conveyor 6.

[0050] The structure of the rotating shaft driving mechanism 33 is the same as that of the horizontal driving mechanism 23, so as to realize the horizontal movement of the rotating shaft clamping frame 31 along the conveying gantry 1. The lifting driving mechanism 34 comprises a lifting driving cylinder, the cylinder body of which is fixed on the rotating shaft clamping frame 31 in the vertical direction, and the output rod of which is connected to the rotating shaft clamping seat 32. The lifting driving cylinder can drive the rotating shaft clamping seat 32 to slide along the vertical direction on the rotating shaft clamping frame 31.

[0051] The rotating shaft clamping seat 32 is provided with a clamping rotating cylinder 35, and the output end of the clamping rotating cylinder 35 is provided with a rotating shaft clamping jaw cylinder 36. Thus, the rotating shaft clamping jaw cylinder 36 is moved to the position of the friction welding device 7 by the rotating shaft driving mechanism 33, the lifting driving cylinder drives the rotating shaft clamping jaw cylinder 36 to be flush with the position of the finished product rotating shaft, the rotating shaft clamping jaw cylinder 36 clamps the finished product rotating shaft out of the friction welding device 7, the finished product rotating shaft is conveyed to the finished product rotating shaft conveyor 6 by the rotating shaft driving mechanism 33, the finished product rotating shaft conveyor 6 is provided with rotating shaft placing frames at intervals, the finished product rotating shaft conveyor 6 can convey the rotating shaft placing frames, and the finished product rotating shafts are conveniently collected by the finished product rotating shaft conveyor 6.

[0052] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application.
