[0019] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0020] like Figure 1 and Figure 2 As shown, an embodiment of the present invention discloses a pin insertion fixture for inserting a pin shaft 200 into the pin holes 103 of the two discs 101 of the prefabricated component 100. The fixture includes: a turntable 10, a feeding mechanism 20, an adjusting mechanism 30, a swing arm mechanism 51, a pin pressing mechanism 40, and a pin feeding mechanism 60.

[0021] The turntable 10 is arranged horizontally, and a first rotation drive mechanism 14 is installed below the turntable 10. The first rotation drive mechanism 14 is used to drive the turntable 10 to rotate and keep the turntable 10 at the angle reached after rotating at a preset angle. The turntable 10 is provided with a plurality of positioning grooves 11, which are evenly distributed circumferentially. The positioning grooves 11 radially penetrate the edge of the turntable 10 and form a slot at the edge of the turntable 10. A positioning hole 12 is provided on the turntable 10 on the radially inner side of each positioning groove 11. The positioning hole 12 radially penetrates the groove wall of the positioning groove 11 and forms a notch. Preferably, the positioning groove 11 is a U-shaped groove. Two rollers 13 are installed on the groove wall of the positioning groove 11, and the wheel surface of the rollers 13 protrudes from the groove wall of the positioning groove 11.

[0022] Feeding station, pinning station and discharge station are arranged in sequence around turntable 10. Feeding mechanism 20 corresponds to the feeding station and pinning mechanism 40 corresponds to the pinning station.

[0023] The feeding mechanism 20 includes two parallel plates 21 defining guide grooves 22. The guide grooves 22 extend radially and have a proximal radial end and a distal radial end. The proximal radial end corresponds to the positioning groove 11 at the feeding station, and the guide grooves 22 are arranged at an angle with the distal radial end higher than the proximal radial end. The prefabricated component 100 slides onto the guide groove 22 from its distal radial end, with its spindle 102 positioned within the guide groove 22 and its disc 101 straddling the two plates 21. Under gravity, the prefabricated component 100 slides towards and into the positioning groove 11 at the feeding station. Furthermore, since rollers 13 are installed on the walls of the positioning groove 11, the outer circumferential surface of the spindle 102 of the prefabricated component 100 contacts the rollers 13, allowing the prefabricated component 100 to rotate.

[0024] After the prefabricated component 100 is received by the positioning groove 11 at the feeding station, the first rotation drive mechanism 14 drives the turntable 10 to rotate to move the prefabricated component 100 to the pin station. The adjustment mechanism 30 first corrects the pin hole 103 of the prefabricated component 100 that has been moved to the pin station, specifically so that the positioning pin on the disc body 101 of the prefabricated component 100 is rotated to a position coaxial with the positioning hole 12 of the positioning groove 11. The adjustment mechanism 30 is used to rotate the pin hole 103 on the disc body 101 of the prefabricated component 100 to a position coaxial with the positioning hole 12.

[0025] The adjustment mechanism 30 is located on the periphery of the turntable 10 and between the feeding station and the pin station. The adjustment mechanism 30 includes a linear drive mechanism 31, a second rotation drive mechanism 32 mounted on the linear drive mechanism 31, a friction wheel 33 mounted on the second rotation drive mechanism 32, and an infrared sensor 34. The linear drive mechanism 31 can drive the second rotation drive mechanism 32 to move the friction wheel 33 closer to or away from the turntable 10. The infrared sensor 34 is arranged below the turntable 10, and after the prefabricated component 100 rotates to the pin station, the probe of the infrared sensor 34 is coaxial with the positioning hole 12 on the radially inner side of the positioning groove 11 and emits detection light upward. Before the prefabricated component 100 rotates to the pin station, the linear drive mechanism 31 moves the friction wheel 33 away from the turntable 10. After the prefabricated component 100 rotates to the pin station, the linear drive mechanism 31 drives the friction wheel 33 to approach the turntable 10 and contact the edge of the disc body 101 of the prefabricated component 100. The second rotation drive mechanism 32 drives the friction wheel 33 to rotate so as to drive the prefabricated component 100 to rotate, and makes the pin hole 103 of the prefabricated component 100 coaxial with the positioning hole 12 on the turntable 10 (based on the fact that the light emitted by the infrared sensor 34 is not blocked by the prefabricated component 100 to determine that the pin 200 is coaxial with the positioning hole 12).

[0026] The pin feeding mechanism 60 is located on the periphery of the turntable 10. The pin feeding mechanism 60 includes a pin feeding guide rail 61 and a transverse guide rail 62 that intersects the pin feeding guide rail 61 perpendicularly. The height of the side where the pin feeding guide rail 61 intersects the transverse guide rail 62 is lower than that of the other side of the pin feeding guide rail 61. A pin shaft 200 is arranged inside the pin feeding guide rail 61. Under the action of gravity and vibration, the pin shaft 200 slides to one side of the transverse guide rail 62. The pushing mechanism 63 is used to send the pin shaft 200 at the intersection of the pin feeding guide rail 61 and the transverse guide rail 62 to the near end of the transverse guide rail 62 for the pin pressing mechanism 40 to pick up.

[0027] The swing mechanism 50 drives the pin-pressing mechanism 40 to swing, thereby horizontally transporting the pin 200 above the prefabricated component 100 at the pin-mounting station. Specifically, the swing mechanism 50 includes a column 52, a swing arm 51 mounted on the upper end of the column 52, and a third rotation drive mechanism 53 that drives the column 52 to rotate, thereby causing the swing arm 51 to swing horizontally back and forth. A cylindrical gear 54 is mounted on the column 52, and a sector gear 55 is mounted on the output shaft of the third rotation drive mechanism 53. The sector gear 55 meshes with the cylindrical gear 54 on the column 52, thereby enabling the third rotation drive mechanism 53 to drive the column 52 to swing the swing arm 51 horizontally. The pin-pressing mechanism 40 is vertically fixed to the swing arm 51. The pin-pressing mechanism 40 includes a cylinder 41 and a magnet 42 mounted on the lower end of the piston rod of the cylinder 41.

[0028] After the prefabricated component 100 is moved to the pin insertion station, the third rotation drive mechanism 53 drives the swing arm 51 to drive the pin pressing mechanism 40 to rotate horizontally above the pin shaft 200 of the pin feeding mechanism 60. Then, the cylinder 41 of the pin pressing mechanism 40 drives the piston rod to extend and attract and pick up the pin shaft 200 by means of the magnet 42. Then the piston rod retracts. Then, the third rotation drive mechanism 53 drives the swing arm 51 to drive the pin pressing mechanism 40 to rotate above the prefabricated component 100 and face the pin hole 103 of the prefabricated component 100. Then, the piston rod extends again to drive the pin shaft 200 through the pin hole 103. Then, the piston rod retracts again, thereby completing the pin insertion process.

[0029] After the pinning process is completed at the pinning station, the first rotation drive mechanism 14 drives the turntable 10 to rotate to rotate the prefabricated component 100 with the pin 200 inserted to the discharge station. The prefabricated component 100 is moved radially outward by manual labor and mechanical equipment. At this time, the pin 200 is dislodged from the notch of the positioning hole 12, and thus the prefabricated component 100 is finally dislodged from the positioning groove 11.

[0030] The first, second, and third rotation drive mechanisms 53 mentioned above can be rotary motors or rotary cylinders 41, and the linear drive mechanism 31 mentioned above can be linear motors or linear cylinders 41.
