The second station 5 is specifically the manual loading station 10, and the accessories are manually placed at the second station 5. In the corresponding assembly position of the clamp structure 3, the third station 6 is specifically the bolt feeding station 11, and the fourth station 7 is specifically the bolt locking station 12.
 The central part of the circular track 2 is a fixed workbench structure 13, the workbench structure 13 is provided with a vertical lock bolt track 14 corresponding to the fourth station 7, and the side of the lock bolt structure 15 is embedded in the vertical direction. Lock the bolt track 14, the locking part of the bolt structure 15 is located directly above the clamp structure 3 of the fourth station 7;
 The locking bolt structure 15 includes a locking center screwdriver 16, a drive motor 17, a guide spring 18, a vertical drive cylinder 19, an upper mounting seat 20, and a lower mounting seat 21. The inner sides of the upper mounting seat 20 and the lower mounting seat 21 are respectively embedded in the vertical A guide spring 18 is arranged between the upper mounting seat 20 and the lower mounting seat 21 to lock bolt track 14, the vertical drive cylinder 19 is fixed to the vertical lock bolt track, and the piston rod of the vertical drive cylinder 19 is fixed to the upper mounting seat. 20. A drive motor 17 is fixedly mounted on the lower mounting base 21 directly above the fourth station 7, and the lower output end of the drive motor 17 is exposed below the bottom end surface of the lower mounting base 21, and the lower output end of the drive motor 17 is fixedly mounted There is a locking center screwdriver 16, and the locking center screwdriver 16 is arranged toward the upper driving center of the bolt. The vertical drive cylinder 19 drives the upper mounting seat 20 to go down, and drives the lower mounting seat 21 to go down until the locking center driver 16 is attached to the corresponding bolt. Then adjust the vertical position under the action of the guide spring 18, and then drive the motor 17 to rotate, and at the same time drive the cylinder 19 down vertically until the central screwdriver 16 is locked and the bolt is fastened to the corresponding nut, and then the central screwdriver 16 is locked and installed on the top The seat 20 and the lower mounting seat 21 are reset, waiting for the next structure to be tightened;
 A bolt clamping structure 22 is provided directly above the third station 6, one side of the bolt clamping structure 22 is fixed to the first vertical lifting structure 23, and the first vertical lifting structure 23 is arranged outside the circular track 2 , The bolt clamping structure 22 is arranged at the position of the discharge port of the bolt feeding track 24, and the inlet of the bolt feeding track 24 is connected to the outlet of the bolt hopper 25;
 A finished product blanking station 8 is provided on one side of the first station 4, and the finished product blanking station 8 includes a contoured clamping jaw 26, which is used to clamp the finished product. The mounting base 27 of the clamping jaw 26 is fixed to the output block of the horizontal and lateral translation structure 28, which extends to the finished chute area 30, and the base of the horizontal and lateral translation structure 28 is fixed to the second vertical The output block of the lifting structure 29, the bottom of the second vertical lifting structure 29 is fixed to the frame 1;
 The position of the first station 4 is provided with a sensor (not shown in the figure, arranged according to the actual situation). The sensor is used to detect whether the finished product in the fixture structure 3 corresponding to the first station 4 has been removed, and the finished product is After removal, the nut loading station 9 moves to put the nut into the corresponding nut placement position in the fixture structure 3;
 The nut loading station 9 includes a nut clamping structure 31, one side of the nut clamping structure 31 is fixed to the third vertical lifting structure 32, and the base of the third vertical lifting structure 32 is fixed to the horizontal and vertical translation structure 33 In the output block, the nut clamping structure 31 in the nut-taking state is located at the outlet of the nut feeding rail 34, and the inlet of the nut feeding rail 34 is connected to the outlet of the nut hopper 35.
 The working process is as follows. Turn on the power switch of the automatic bolt-locking machine, and the machine can work. Driven by the circular track, each fixture structure stops in sequence to the first station, the second station, the third station, and the fourth station. Station, and then cycle:
 1. The first station: the nut loading station automatically loads nuts;
 2. The second station: Place rollers and roller brackets at the manual loading station;
 3. The third station: The bolt feeding mechanism takes a bolt from the automatic bolt feeding and places it in the roller hole;
 4. The fourth station: automatically lock bolts at the bolt-locking station;
 5. The first station: The finished product blanking station has priority over the nut loading station, and the finished product blanking station takes out the finished product and places it in the chute;
 6. The first station: the nut loading station automatically loads nuts;
 7. Each fixture structure works in turn.
