[0047] As Figure 12As shown, the torsion spring longitudinal drive assembly includes a torsion spring longitudinal cylinder 52, one end of the torsion spring longitudinal cylinder 52 is connected to the torsion spring transfer rack 51 through a torsion spring transverse drive assembly, and the other end is an output end and is provided with a torsion spring movable plate 53. The torsion spring transfer seat 7 is installed on the torsion spring movable plate 53, and the torsion spring transfer seat 7 is driven to move axially back and forth by the torsion spring longitudinal cylinder 52. The torsion spring transverse drive assembly includes a torsion spring transverse mounting seat 54 arranged on the torsion spring transfer rack 51, a torsion spring transverse cylinder 55 arranged on one side of the torsion spring transverse mounting seat 54, and a torsion spring transverse movable plate 56 arranged on the side of the torsion spring longitudinal cylinder 52 close to the torsion spring transverse mounting seat 54. The torsion spring longitudinal cylinder 54 is arranged on the torsion spring transverse movable plate 56, and the torsion spring transverse cylinder 55 is connected to the torsion spring transverse movable plate 56, and drives the torsion spring transfer seat 7 to move radially back and forth along the torsion spring transverse mounting seat 54.

[0048] like Figures 1-7 As shown, when the torsion spring assembly mechanism of the present invention is used on the automatic assembly line of razor heads, its main function is to extract the torsion spring 14 at the torsion spring fixture 41 and send it to the cutter head fixture loaded with the cutter head shell 1, fixed blade 11, movable blade 12, and pressure block 13, so that the torsion spring transfer mechanism 5 replaces the worker to assemble the torsion spring 14 with the cutter head shell 1, and its torsion arm 142 will be installed in the card groove 131 at both ends of the pressure block 13, and the torsion spring body 141 and the torsion spring connecting part 143 will be installed in the card seat 15 and the connecting part seat 16 on the cutter head shell 1 respectively, wherein the torsion spring 14 is uniformly placed on the torsion spring vibration disk 64, and enters the torsion spring conveying channel 63 in the same state after being screened by the torsion spring vibration disk 64. At this time, the torsion spring conveying marbles 66 and the torsion spring conveying spring 65 form an elastic buckle structure that is clamped on the torsion spring conveying channel 63 near the torsion spring fixture 41. In this state, the torsion spring conveying marble 66 will pop out of the torsion spring conveying plate 61 due to the elastic force of the torsion spring conveying spring 65, thereby preventing the tilted torsion spring 14 from sliding down due to its gravity, and the torsion spring feeding claw 68 is set on both sides of the torsion spring conveying channel 63. The torsion spring feeding cylinder 69 can drive the torsion spring 14 at the lower end to move downward and press the torsion spring conveying marble 65 into the torsion spring conveying plate 61, thereby making the torsion spring 14 slide into the torsion spring clamp 41 of the attachment. After completion, the feeding reset cylinder 691 will drive the torsion spring feeding claw 68 to move downward and then rise through the torsion spring feeding cylinder 69. The feeding reset cylinder 691 will then send the torsion spring feeding claw 68 to the upper position of the current lowermost torsion spring 14, thereby forming a quadrilateral motion trajectory and completing the reset, thereby enabling the torsion spring feeding assembly to intermittently send the torsion spring 14 from the torsion spring conveying channel 63 to the torsion spring clamp 41, thereby realizing automated mechanical feeding.

[0049] like Figures 8-11As shown, when the torsional spring 14 in the torsional spring conveying mechanism enters the torsional spring clamp, the body positioning pull plate 441 pulls the torsional spring body 141 into the torsional spring accommodating groove 411, and cooperates with the torsional spring clamp 41, so that the torsional spring body 141 enters the torsional spring accommodating groove 411 and stays above the torsional spring ejection plate 431, and the torsional arm positioning push plate 451 pushes the two sides of the torsional arm 142 to the body positioning pull plate 441, so that the two sides of the torsional arm 142 are deformed to the middle, and then the torsional arm 142 stays in the torsional arm positioning space 46 between the torsional arm positioning push plate 451 and the body positioning pull plate 441, so that the torsional arm 142 stays above the torsional spring ejection plate 432, and the torsional spring 14 is fixed to avoid being rotated and falling off. At this time, the torsional spring rotating drive machine (motor) 42 drives the two sides of the torsional spring clamp 41 on the torsional spring ejection seat 4 to adjust the position, and is accurately positioned through the bottom photoelectric sensor, so that the torsional spring conveying mechanism on this side can wait for feeding, and the torsional spring clamp 41 at the other end can transfer the torsional spring 14 in the torsional spring clamp 41 to the second tool clamp 31 of the torsional spring assembly station A through the torsional spring rotating mechanism 5, so as to realize one-to-wait, improve the efficiency of torsional spring assembly, and realize automatic assembly of the torsional spring.

[0050] As Figure 3 , Figures 8-15As shown, when the torsional spring transfer seat 7 extracts the torsional spring 14 at the torsional spring clamp 41, the torsional spring longitudinal cylinder 52 drives the body profiling groove 71 and the torsional arm clamping groove 72 of the torsional spring transfer seat 7 to be in abutment with the torsional spring accommodating groove 411 and the torsional arm positioning space 46 at the torsional spring clamp 41 respectively, at this time the torsional spring top charging cylinder 43 drives the torsional spring top charging plate 431 and the torsional spring top charging piece 432 to pass through the torsional spring clamp 41, and then the torsional spring 14 is topped away from the torsional spring clamp 41 and enters the torsional spring transfer seat 7, wherein the body locking cylinder 73 drives the body locking shaft 74 to penetrate into the torsional spring body 141 to fix the torsional spring body 141 on the body profiling groove 71, the torsional arm 142 is fixed by the elastic potential on both sides abutting in the arc hole-shaped torsional arm clamping groove 32, at this time the pressing block locking cylinder 33 on the fixed disc 32 drives the pressing block locking rod 34 to insert into the pressing block 13 in the torsional spring assembly station A to fix the pressing block 13, then the torsional spring longitudinal cylinder 53 and the torsional spring transverse cylinder 55 bring the torsional spring 14 to abut with the second tool head clamp 31 above the second indexing disc 3, at this time the body locking cylinder 73 drives the body locking shaft 74 to disengage from the torsional spring body 141, the body unloading cylinder 75 drives the body unloading plate 751 to pass through the torsional spring transfer seat 7, and then pushes the torsional spring body 141 out of the body profiling groove 71, and then covers the torsional spring body 141 in the clamping seat 15, the torsional arm unloading cylinder 77 drives the torsional arm unloading ejector pin 771 to pass through the torsional arm unloading hole 76, and then pushes the torsional arm 142 on both sides out of the torsional arm clamping groove 72, and clamps the torsional arm 142 in the pressing block clamping groove 131 on both sides of the pressing block 13, at the same time the torsional arm unloading cylinder 77 also synchronously drives the connecting part unloading plate 773 to pass through the connecting part unloading groove 78, and then pushes the torsional spring connecting part 143 out of the connecting part unloading groove 78, and then clamps the torsional spring connecting part 143 into the connecting part seat 16 of the tool head housing 1, realizing the full-automatic assembly of the torsional spring.
