The pin hole 1011 of the outer cover 101 is a through hole to allow the pin 105 to pass through. The carrier rear wall 152 is fixedly provided with a plug rod seat sleeve 158, and a pre-insertion positioning rod 159 can slide horizontally in the seat sleeve. The rod end of the pre-insertion positioning rod 159 is opposite to the front wall hole 153 to realize accurate alignment of the shaft 104 with the hole position of the outer cover 101. The front wall hole 153 and the carrier rear wall 152 are also provided with a square avoiding groove 154 to facilitate the clamping of the outer cover 101 by the clamping jaw.

[0057] The outer cover mounting assembly 1 is used to place the outer cover 101 in the fixed carrier 150; the inner seat mounting assembly 2 located at the inner seat mounting workstation is used to place the inner seat 102 in the outer cover.

[0058] The pin installation assembly 5 at the pin installation station includes a pin installation mechanism and a pin conveying mechanism 50 for conveying the pin; the pin positioning mechanism 86 is used to press down the shaft 104 to maintain the current position; the pin installation mechanism is used to horizontally insert the conveyed pin 105 through the shaft 104 and the outer cover 101 and to top off the pre-insertion positioning rod 159 (partly). The pin riveting assembly 7 at the pin riveting station is used to rivet the pin at one end to form a twist lock product.

[0059] In order to enable the pin 105 to be inserted in place and to avoid the product from being unable to be removed due to the pre-insertion positioning rod 159 not being fully reset, the equipment table 145 is further provided with a pin insertion station between the pin installation station and the pin riveting station; the insertion positioning mechanism 82 is fixedly arranged on the fixed disc corresponding to the pin insertion station; the insertion positioning mechanism 82 is used to press down the shaft 104 to maintain the current position. The twist lock automatic assembly equipment further includes a pin insertion assembly 6 at the pin insertion station, which is used to top punch the inserted pin into place and to fully reset the pre-insertion positioning rod 159.

[0060] The conveying mechanism of each part, such as the outer cover conveying mechanism 10, the inner seat conveying mechanism 20, the spring conveying mechanism 30, the shaft conveying mechanism 40 and the pin conveying mechanism 50, is preferably a vibration disc conveying mechanism, which can arrange the scattered parts in an orderly manner and convey them to the designated position to wait for the gripper to grab.

[0061] Referring to Figure 13 The outer cover installation assembly 1 includes an outer cover installation mechanism and an outer cover conveying mechanism 10; the outer cover conveying mechanism 10 is used to convey the outer cover 101; and the outer cover installation mechanism is used to place the conveyed outer cover 101 into the fixed carrier 150. The outer cover installation assembly 1 is mainly composed of a three-axis motion mechanism. The outer cover moving mechanism 11 is a linear module arranged horizontally to realize reciprocating motion in the X-axis direction. The outer cover moving mechanism 11 is provided with an outer cover vertical moving mechanism 12 arranged vertically, which is a linear module or a pneumatic cylinder to realize lifting in the Z-axis direction. The outer cover vertical moving mechanism 12 is connected with an outer cover carrying mechanism 13, which is provided with an outer cover electric gripper 14 and an outer cover rotating part (such as a rotating motor) for adjusting the posture.

[0062] Specifically, the cover mounting mechanism comprises: a cover moving mechanism 11, a cover vertical moving mechanism 12 horizontally reciprocally arranged on the cover moving mechanism 11, and a cover carrying mechanism 13 vertically reciprocally arranged on the cover vertical moving mechanism 12; wherein the cover carrying mechanism 13 is provided with a cover rotating part and a cover electric clamp 14 connected below the cover rotating part; the cover electric clamp 14 is used for clamping the cover 101; the cover rotating part can rotate the cover electric clamp 14 around a vertical axis to rotate the incoming material by 90 degrees. A plurality of cover vertical moving mechanisms 12 are arranged on the cover moving mechanism 11, and each cover vertical moving mechanism 12 is provided with one cover carrying mechanism 13.

[0063] At this station, the cover conveying mechanism 10 (such as a vibrating disc) sends the cover 101 to the material taking position. The cover electric clamp 14 is lowered and grabs the cover 101, and the cover vertical moving mechanism 12 lifts it. Then the cover moving mechanism 11 is translated to directly above the fixed carrier 150. If necessary, the cover rotating part can rotate the cover horizontally by 90 degrees to adjust the posture, and finally the cover vertical moving mechanism 12 is lowered to accurately place the cover 101 into the carrier groove.

[0064] Referring to Figure 13 , the inner seat mounting assembly 2 comprises an inner seat mounting mechanism and an inner seat conveying mechanism 20; the inner seat conveying mechanism 20 is used for conveying the inner seat 102; and the inner seat mounting mechanism is used for placing the conveyed inner seat 102 on the cover 101 on the fixed carrier 150. The structure of the inner seat mounting assembly 2 is basically the same as that of the cover mounting assembly 1. It also comprises an inner seat moving mechanism 21 for horizontal movement, an inner seat vertical moving mechanism 22 for vertical lifting, and an inner seat carrying mechanism 23 provided with an inner seat electric clamp 24 at the end.

[0065] Specifically, the inner seat mounting mechanism comprises: an inner seat moving mechanism 21, an inner seat vertical moving mechanism 22 horizontally reciprocally arranged on the inner seat moving mechanism 21, and an inner seat carrying mechanism 23 vertically reciprocally arranged on the inner seat vertical moving mechanism 22; wherein the inner seat carrying mechanism 23 is provided with an inner seat rotating part (a rotating motor) and an inner seat electric clamp 24 connected below the inner seat rotating part; the inner seat electric clamp 24 is used for clamping the inner seat 102; and the inner seat rotating part can rotate the inner seat electric clamp 24 around a vertical axis to rotate the incoming material by 90 degrees. A plurality of inner seat vertical moving mechanisms 22 are arranged on the inner seat moving mechanism 21, and each inner seat vertical moving mechanism 22 is provided with one inner seat carrying mechanism 23.

[0066] In this station, the carrier rotates to this station, and the inner seat installation assembly 2 repeats the action similar to the outer cover installation. The inner seat electric clamping jaw 24 grabs the inner seat 102 from the inner seat conveying mechanism 20, and after translation and lifting, accurately places it inside the already installed outer cover 101.

[0067] Referring to Figure 14 , the spring installation assembly 3 comprises a spring installation mechanism and a spring conveying mechanism 30; the spring conveying mechanism 30 is used to convey the spring 103; the spring installation mechanism is used to vertically insert the conveyed spring 103 into the shaft hole of the inner seat 102 of the fixed carrier 150.

[0068] Specifically, the spring installation mechanism comprises a spring rotating mechanism 34, a spring moving mechanism 31, a spring vertical moving mechanism 32 horizontally reciprocally arranged on the spring moving mechanism 31, and a spring carrying mechanism 38 vertically reciprocally arranged on the spring vertical moving mechanism 32; wherein the spring carrying mechanism 38 is provided with a spring electric clamping jaw 33; the spring electric clamping jaw 33 is used to clamp the spring 103.

[0069] The spring installation assembly 3 has a unique structure design to adapt to the characteristics of the spring being easily deformed. It comprises a spring carrying mechanism 38 (composed of a spring moving mechanism 31, a spring vertical moving mechanism 32, and a spring electric clamping jaw 33) for grabbing the spring and a spring rotating mechanism 34. The spring rotating mechanism 34 comprises a rotating disc that can rotate around a horizontal axis, and the side of the rotating disc is fixed with a spring inner inserting rod 35 with a diameter slightly smaller than the inner diameter of the spring. The rotating disc is located below the spring carrying mechanism 38 and can switch the spring inner inserting rod 35 between a horizontal receiving position and a vertical feeding position through 90-degree reciprocating rotation.

[0070] In this station, the spring rotating mechanism 34 is located at the horizontal receiving position, and the spring sleeve in the conveying slide of the spring vibrating disc is sleeved into the inner inserting rod 35. Then, it is rotated by 90 degrees, so that the inner inserting rod 35 with the spring becomes a vertical feeding position vertically upward, and the spring electric clamping jaw 33 grabs a spring 103 from the inner inserting rod 35. Then the spring carrying mechanism 38 is lifted and translated, and finally the spring carrying mechanism 38 is lowered as a whole, so that the spring 103 is inserted into the shaft hole of the inner seat 102.

[0071] Referring to Figure 11 , 15, 16, 17, 18. The shaft mounting mechanism comprises a shaft moving mechanism 42, a shaft vertical moving mechanism 43 horizontally reciprocally arranged on the shaft moving mechanism 42, a shaft carrying mechanism 45 vertically reciprocally arranged on the shaft vertical moving mechanism 43, and a hole aligning rotating mechanism 48 below the shaft carrying mechanism 45. The lower end of the shaft carrying mechanism 45 is provided with a shaft electrically operated gripper. The hole aligning rotating mechanism 48 is used to rotate and correct the pin hole 1041 on the shaft 104, and align the pin hole 1041 with the pin hole 1011 on the outer cover 101, so as to facilitate the subsequent penetration of the pin 105. The pin hole 1041 on the shaft 104 is a through hole, so as to facilitate the penetration of the pin 105.

[0072] The hole aligning rotating mechanism 48 comprises a hole aligning bearing seat 483, a hole aligning clamping unit 481, a hole aligning rotating support 49, and a light positioning part. The hole aligning rotating support 49 can be driven to rotate around a vertical axis. The hole aligning clamping unit 481 is arranged on the hole aligning rotating support 49, and is provided with a hole aligning clamping electric chuck 482 thereon. The hole aligning bearing seat 483 is fixedly installed below the hole aligning clamping electric chuck 482. The light positioning part can detect the position of the shaft pin hole, and control the hole aligning clamping electric chuck 482 to clamp and rotate the shaft so that the shaft pin hole is rotated to the target position.

[0073] The upper end of the hole aligning bearing seat 483 is provided with a bearing groove 484, which is coaxial with the hole aligning clamping electric chuck 482 below. The hole aligning rotating support 49 comprises a plurality of circumferentially arranged hole aligning connecting columns 485, and a hole aligning bearing plate fixedly connected to the upper ends of the plurality of hole aligning connecting columns 485. The hole aligning clamping unit 481 is fixedly arranged on the hole aligning bearing plate.

[0074] Two shaft carrying mechanisms 45 are horizontally spaced apart on the shaft moving mechanism 42. One shaft carrying mechanism 45 is used to carry the shaft from the shaft conveying mechanism 40 to the hole aligning rotating mechanism 48, and the other shaft carrying mechanism 45 is used to carry the shaft from the hole aligning rotating mechanism 48 to the fixed bearing 150. The hole aligning clamping electric chuck 482 is released after clamping the shaft by the other shaft carrying mechanism.

[0075] The light positioning part includes a light sensor (not shown) and a light emitter (not shown) that emits light to the through hole. The light sensor and the light emitter can be fixed to the lower surface of the hole bearing plate or the hole connecting column 485, and their approximate positions can be located on both sides of the hole clamping motorized chuck 482 respectively. The light emitter emits light, and the light sensor on the other side of the hole clamping motorized chuck 482 senses the light. When the shaft 104 is located on the hole bearing seat 483, the height of the pin hole on the shaft 104 is the same as the height of the light position. When the hole clamping motorized chuck 482 rotates, the shaft 104 remains stationary, and the light sensor senses the light when the light passes through the pin hole. The controller of the light positioning part can control the hole clamping motorized chuck 482 to clamp and fix the shaft 104, and rotate the pin hole 1041 of the shaft 104 to the target position until the other shaft carrying mechanism clamps the shaft and then releases the shaft, avoiding the shaft 104 from loosening and shifting due to premature release.

[0076] The pre-insertion ramming mechanism 85 includes a first linear drive mechanism and a pre-insertion ramming head 851 driven by the first linear drive mechanism to perform horizontal linear reciprocating ramming; when the fixed carrier 150 rotates to the shaft installation station, the pre-insertion ramming head 851 horizontally faces the pre-insertion positioning rod 159.

[0077] Specifically, the shaft installation assembly 4 includes two parallel shaft carrying mechanisms 45, which are installed on the mechanism synchronization frame 44 and can perform three-dimensional motion under the drive of the shaft moving mechanism 42 and the shaft vertical moving mechanism 43. In the shaft installation assembly 4, the hole rotating mechanism 48 and the pre-insertion ramming mechanism 85 fixed on the equipment fixed disc 8 serve as main functional components. The hole rotating mechanism 48 includes a base, on which a plurality of hole connecting columns 485 support a hole rotating support 49. The support 49 is provided with a hole clamping unit 481, which mainly includes a hole clamping motorized chuck 482 that can rotate with the hole rotating support 49. A hole bearing seat 483 with a bearing groove 484 is coaxially arranged below the hole clamping motorized chuck 482, which is used to initially place and position the shaft 104. The pre-insertion ramming mechanism 85 is a horizontally arranged linear drive mechanism (such as a pneumatic cylinder), which has a pre-insertion ramming head 851 at the end.

[0078] When taking out and aligning, the first shaft handling mechanism 45 grabs the shaft 104 from the shaft conveying mechanism 40 and places it into the bearing slot 484 of the aligning rotating mechanism 48. The aligning clamping motorized chuck 482 is lowered to clamp the shaft 104. The light positioning unit detects the current angle of the pin hole on the shaft 104 and feeds back to the control system, which controls the aligning clamping motorized chuck 482 to rotate until the pin hole is corrected to the target position. When handling and installing, the second shaft handling mechanism 45 moves above the aligning rotating mechanism 48, grabs the shaft 104 with the corrected posture, and handles it above the fixed carrier 150, and then vertically lowers it to insert the shaft into the spring 103. When pre-inserting and positioning, after the shaft 104 is properly placed, the pre-insertion jacking mechanism 85 is activated, and the jacking head 851 pushes the pre-insertion positioning rod 159. The pre-insertion positioning rod 159 passes through the carrier front wall hole 153, the pin hole 1011 of the outer cover 101, and the calibrated pin hole 1041 on the shaft 104, achieving accurate temporary locking of the outer cover and the shaft.

[0079] Referring to Figure 10 、 19 , the pin mounting assembly comprises a pin conveying mechanism 50, a pin moving mechanism 51, a pin vertical moving mechanism 52 horizontally reciprocally arranged on the pin moving mechanism 51, and a pin handling mechanism 53 vertically reciprocally arranged on the pin vertical moving mechanism 52; wherein the pin handling mechanism 53 is provided with a pin motorized clamping jaw; the pin motorized clamping jaw is used to clamp the pin 105.

[0080] The pin conveying mechanism 50 comprises a pin vibrating disc, a conveying slot 505, a pin handling base 57 arranged at the end of the conveying slot 505, and a pin detection unit 55 for detecting the pin. The pin handling base 57 has a pin placing slot 571 and pin taking-out slots 572 located on both sides of the pin placing slot 571, which can move along the horizontal direction perpendicular to the conveying slot 505 to switch between the pin taking-in position and the pin feeding position. The pin taking-out slots 572 are arranged close to the pin head position. When the pin handling base 57 is at the pin taking-in position, the pin placing slot 571 is located in front of the conveying slot 505 in communication; when the pin handling base 57 is at the pin feeding position, the pin taking-out slots 572 are located directly below the pin motorized clamping jaw.

[0081] The pin inserting positioning mechanism 86 comprises a pin support 861, a first downward driving mechanism 862 mounted on the pin support 861, and a first downward head 863 vertically and linearly reciprocally moved by the first downward driving mechanism 862; when the fixed carrier 150 rotates to the pin mounting station, the first downward head 863 vertically faces the shaft 104.

[0082] The moving part of the pin inserting assembly 5 is mainly composed of a pin moving mechanism 51, a pin vertical moving mechanism 52 and a pin carrying mechanism 53, and the end is a pin carrying electric clamp jaw 54. The pin positioning mechanism 86 fixed on the equipment fixed disc 8 is a vertical driving mechanism with a first pressing head 863. In operation, the first pressing head 863 of the pin positioning mechanism 86 first descends and gently presses the top end of the shaft 104 to prevent it from moving during pin insertion. The pin carrying electric clamp jaw 54 grabs a pin 105 from the pin feeding mechanism 50. Then, the clamp jaw moves horizontally to the side of the fixed carrier 150, aligns the pin 105 with the free end of the pre-insertion positioning rod 159, and pushes it forward horizontally. The front end of the pin 105 smoothly partially ejects the pre-insertion positioning rod 159 from the other end, completing the relative displacement of the position.

[0083] Referring to Figure 20 , 21 . The pin inserting assembly 6 includes a pin ejecting mechanism 61, which includes a second linear driving mechanism and an inserting ejecting head driven by the second linear driving mechanism for horizontal linear reciprocating ejection; when the fixed carrier 150 rotates to the pin inserting station, the inserting ejecting head is horizontally opposite to the pin installed by the pin installing mechanism.

[0084] The inserting positioning mechanism 82 includes an inserting support 821, a second pressing driving mechanism 822 installed on the inserting support 821, and a second pressing head driven by the second pressing driving mechanism 822 for vertical linear reciprocating movement; when the fixed carrier 150 rotates to the pin inserting station, the second pressing head is vertically opposite to the shaft 104. The inserting positioning mechanism 82 is similar to the pin positioning mechanism 86, and the repeated parts will not be described again.

[0085] The pin inserting assembly 6 mainly includes a horizontally arranged pin ejecting mechanism 61 (such as a small air cylinder). At the same time, the fixed disc 8 is provided with an inserting positioning mechanism 82 corresponding to this station, which is similar in structure to the pin positioning mechanism 86 and is also a vertical pressing device. In operation, when the carrier rotates to this position, the inserting positioning mechanism 82 presses the shaft 104 to fix the position. The pin ejecting mechanism 61 is quickly started to give a short and forceful impact on the tail of the inserted pin 105, ensuring that the pin is completely inserted in place, eliminating the installation allowance, and making the pre-insertion positioning rod 159 completely reset.

[0086] Referring to Figure 23 , 24,25. The pin riveting assembly 7 comprises a flanging mechanism 75, a lock body moving mechanism 71, a lock body vertical moving mechanism horizontally reciprocally arranged on the lock body moving mechanism 71, and a lock body carrying mechanism vertically reciprocally arranged on the lock body vertical moving mechanism; wherein the lock body carrying mechanism 73 is provided with a lock body rotating component (such as a rotating motor) and a lock body electric clamp jaw 74 connected below the lock body rotating component; the lock body electric clamp jaw 74 is used for clamping the outer cover of the rotating lock; the lock body rotating component can rotate the lock body electric clamp jaw 74 around a vertical axis to place the rotating lock in the flanging mechanism 75 after rotating the rotating lock by 90 degrees.

[0087] The flanging mechanism 75 comprises a flanging carrier 755 and impact mechanisms 751 located on both sides of the flanging carrier 755; both sides of the flanging carrier 755 are respectively provided with impact through holes 756; when the rotating lock is placed on the flanging carrier 755, both ends of the pin respectively face the impact through holes 756 on both sides; the impact mechanism 751 comprises an impact driving mechanism and an impact rod 753 driven by the impact driving mechanism; the rod end of the impact rod 753 is provided with an impact head capable of extending into the impact through hole 756 to impact the pin to form a flange.

[0088] The pin riveting assembly 7 further comprises a finished product carrying mechanism 76 and a finished product conveying groove 78; the finished product carrying mechanism 76 and the lock body carrying mechanism 73 are jointly installed on the lock body vertical moving mechanism to move synchronously; the finished product carrying mechanism 76 comprises a finished product electric clamp jaw 77 used for clamping the shaft of the rotating lock; wherein the lock body carrying mechanism 73 is used for placing the rotating lock in the flanging carrier 755 after rotating the rotating lock from the fixed carrier 150; the finished product carrying mechanism 76 is used for carrying the rotating lock after flanging the flanging carrier 755 to the finished product conveying groove 78.

[0089] The pin riveting assembly 7 is the core of the finished product process. It comprises a lock body moving mechanism 71 for carrying, a riveting vertical moving mechanism 72, a lock body carrying mechanism 73 (with a lock body electric clamp jaw 74), and a finished product carrying mechanism 76 (with a finished product electric clamp jaw 77). The core device is the flanging mechanism 75, which comprises a flanging carrier 755 with a groove matching the shape of the rotating lock, impact through holes 756 are respectively opened on both sides of the carrier, and impact mechanisms 751 are correspondingly arranged outside the through holes. Each impact mechanism 751 is composed of an impact driving mechanism (such as a powerful cylinder) and an impact rod 753 capable of performing impact motion under the driving of the impact driving mechanism.

[0090] For the pin riveting station, when taking and placing, the lock body electric clamping jaw 74 is lowered to clamp the rotating lock semi-finished product in the fixed carrier 150, then is lifted, rotated by 90 degrees, and accurately placed on the flanging carrier 755. At this time, the two ends of the pin 105 are opposite to the impact through holes 756 on the two sides. When flanging and riveting, the impact mechanisms 751 on the two sides are started, the impact rods 753 are extended at high speed, the front ends of the impact rods 753 impact the two ends of the pin with great force, the material at the ends of the pin is plastically deformed, flanges are formed, and the pin is permanently fixed. When the finished product is discharged, after riveting is completed, the finished product electric clamping jaw 77 of the riveting finished product conveying mechanism 76 is lowered to clamp the completed rotating lock finished product, the completed rotating lock finished product is taken out of the flanging carrier 755, and is placed in the finished product conveying groove 78, thereby completing a complete automatic assembly cycle.

[0091] In combination Figures 1 to 25 The working process of the embodiment is described in detail below, so that the application can be better understood.

[0092] After the equipment is started, the carrier rotating ring disc 9 is stepwise rotated to sequentially send the empty fixed carrier 150 to each station to complete corresponding assembly tasks.

[0093] The cover mounting station: the cover mounting assembly 1 is responsible for mounting the cover 101 into the fixed carrier 150. The cover conveying mechanism 10 sends the cover to a taking position. The cover electric clamping jaw 14 on the cover conveying mechanism 13 is lowered to grab the cover 101, is lifted through the cover vertical moving mechanism 12, is translated to above the fixed carrier 150 through the cover moving mechanism 11, and is finally lowered to accurately place the cover 101 into the carrier groove.

[0094] The inner seat mounting station: the structure and action of this station are similar to those of the cover mounting station. The inner seat electric clamping jaw 24 of the inner seat mounting assembly 2 takes the inner seat 102 from the inner seat conveying mechanism 20, accurately places the inner seat 102 into the already mounted cover 101 through translation and vertical movement.

[0095] The spring mounting station: referring to Figure 14 , the design of the spring mounting assembly 3 is unique. The spring rotating mechanism 34 is located at a horizontal taking position, the spring 103 in the conveying slide of the spring vibrating disc is sleeved on the inner inserting rod 35. Then, the inner inserting rod 35 with the spring 103 is rotated by 90 degrees to become a vertical feeding position vertically upward. The spring electric clamping jaw 33 grabs the spring 103 from the inner inserting rod 35. Then, the spring conveying mechanism 38 is lifted and translated, and finally, the spring conveying mechanism 38 is lowered as a whole to insert the spring 103 into the shaft hole of the inner seat 102.

[0096] The shaft mounting station: referring to Figure 11 , 15, 16, 17 and 18, in particular comprising the following steps:

[0097] Shaft hole alignment and handling: The shaft mounting assembly 4 comprises two shaft handling mechanisms 45. The first handling mechanism picks up a shaft 104 from the shaft feeding mechanism 40 and places it on the hole alignment carrier 483 of the hole alignment rotation mechanism 48.

[0098] Hole alignment rotation mechanism 48: This mechanism is the core of the pin hole alignment. The shaft 104 is placed in the carrier slot 484 and the hole alignment clamping motorized chuck 482 above clamps it. The optical positioning unit detects the current angle of the pin hole on the shaft 104 and controls the rotation of the hole alignment rotation support 49 until the pin hole is rotated to the preset target position.

[0099] Pre-insertion positioning: The second shaft handling mechanism picks up the shaft 104 with the corrected posture from the hole alignment rotation mechanism 48 and vertically inserts it into the spring 103 of the fixed carrier 150. At this time, the pre-insertion ramming mechanism 85 (such as a pneumatic cylinder or an electric cylinder) fixed on the equipment fixing disc 8 is activated, and its ramming head pushes the pre-insertion positioning rod 159 on the fixed carrier 150. The pre-insertion positioning rod 159 passes through the carrier front wall hole 153, the pin hole 1011 of the outer cover 101 and the pin hole 1041 of the shaft 104, thereby accurately temporarily locking the outer cover 101 and the shaft 104, preparing for the subsequent insertion of the pin.

[0100] Pin installation station: The carrier is rotated to this station. The first lower head of the pin positioning mechanism 86 fixed on the equipment fixing disc 8 is activated to lightly press down the top end of the shaft 104 to prevent it from floating during the pin insertion process. The pin electric clamping jaw 54 on the pin handling mechanism 53 of the pin mounting assembly 5 takes the pin 105 from the pin feeding mechanism 50. Subsequently, the pin handling mechanism 53 moves horizontally to align the pin 105 with the position where the pre-insertion positioning rod 159 is located, and inserts it horizontally. During the insertion process, the front end of the pin 105 smoothly pushes the pre-insertion positioning rod 159 out from the other end, completing the "replacement" of the pin 105 to the pre-insertion positioning rod 159, thereby ensuring the accurate implantation of the pin 105.

[0101] Pin seating station: To ensure that the pin 105 is completely in place, the equipment is provided with this station. Referring to Figure 19 , the carrier is rotated to this station, and the second lower head of the seating positioning mechanism 82 (similar in structure to the pin positioning mechanism 86) fixed on the equipment fixing disc 8 presses down the fixed shaft 104. The pin ramming mechanism 61 (such as a small stamping pneumatic cylinder) of the pin seating assembly 6 located outside the station is activated, and its seating ramming head performs a quick impact on the tail of the pin 105, ensuring that the pin is completely inserted in place, while the pre-insertion positioning rod 159 is completely reset.

[0102] Pin riveting station: This is the last step to form the final product. Referring to Figures 21 to 23.

[0103] Pick and place: the lock body electric gripper 74 of the lock body handling mechanism 73 is lowered to clamp the spin lock semi-finished product (clamping cover 101 part) in the fixed carrier 150, then it is lifted, rotated 90 degrees, and placed on the flanging carrier 755 in the flanging and riveting assembly 7.

[0104] Flanging and riveting: the impact through holes 756 are opened on both sides of the flanging carrier 755, and the ends of the pin 105 of the spin lock are exposed at the impact through holes 756 after being placed. The impact mechanisms 751 on both sides (impact rods 753 driven by impact driving mechanisms) are started simultaneously or sequentially, the impact heads of the impact rods 753 are inserted into the through holes, and the ends of the pin are impacted to cause plastic deformation of the ends to form flanges, thereby firmly locking the pin on the shaft 104 and the cover 101 to form the spin lock 100 finished product.

[0105] Finished product unloading: after riveting is completed, the finished product handling mechanism 76 that moves synchronously with the lock body handling mechanism 73 is started, the finished product electric gripper 77 thereof is lowered to clamp the shaft 104 part of the finished product, which is taken out of the flanging carrier 755 and placed in the finished product conveying groove 78, completing a complete production cycle.

[0106] In this embodiment, the spin lock automated assembly equipment realizes full-process automated assembly from part feeding to finished product riveting by setting a rotary equipment table 145 and multiple automated functional stations distributed in the circumferential direction thereof. The stations work cooperatively with compact rhythm, greatly improving production efficiency. In particular, the precise positioning problem of the shaft and the cover is ingeniously solved by setting the pre-insertion positioning rod 159 and the pre-insertion and punching mechanism 85, and the pin is installed by the pin installation assembly 5 in a replacement manner, ensuring the accuracy of pin insertion. The spin lock automated assembly equipment realizes efficient, accurate, and fully automated assembly of the spin lock.
