Subsequently, the feeding manipulator 35 on the feeding mechanism 9 clamps a frame base combination 1 to be assembled from the feed line 34 through the clamping jaw 38 on the workpiece clamping head 36; then, the cylinder on the workpiece chuck 36 drives the feeding verification pin 39 to move up and down, if the feeding verification pin 39 can be inserted into the assembly hole on the frame base combination piece 1, the clamping posture of the workpiece chuck 36 is correct, otherwise, the clamping posture is incorrect. If the clamping posture of the workpiece clamp 36 is wrong, the workpiece clamp 36 places the clamped frame base assembly 1 at other positions, then clamps the new frame base assembly 1 again, and then the feeding verification pin 39 acts to verify the clamping posture of the frame base assembly 1. The operation is repeated until the workpiece chuck 36 clamps the frame seat combination piece 1 with correct posture; then the feeding manipulator 35 places the frame base combination piece 1 on the main bearing table 18 and the auxiliary bearing table 19 on the workpiece clamp 7 through the workpiece clamp 36, and at the moment, the frame base combination piece 1 is inserted into and connected with the positioning boss 32 on the auxiliary bearing table 19 and is inserted into and connected with the positioning pin 25 on the main bearing table 18; and then the holder-in-place bonding tool 1 can be pressed and fixed on the main bearing table 18 and the auxiliary bearing table 19 by the bonding tool pressing plate 22 under the cooperation of the pressing cylinder 20 and the rotating cylinder 21. At the moment, a frame seat combining piece 1 and a cradle subassembly 2 are fixedly arranged on a workpiece clamp 7 corresponding to the feeding mechanism 9.
After the holder-on-holder assembly 1 is fixed on the workpiece holder 7 by the assembly pressing plate 22, the index plate 6 rotates one station, and at this time, the workpiece holder 7 with the holder-on-holder assembly 1 and the cradle subassembly 2 rotates along with the index plate 6 to correspond to the pin checking mechanism 10. Then, the cylinder on the workpiece clamp 7 drives the action extrusion rod 31 to be inserted into the cradle subassembly 2, and then the positioning sheet 4 in the cradle subassembly 2 is extruded to the assembly station.
The extrusion rod 31 keeps still after acting, and then the pushing cylinder 26 pushes the sliding plate 27 to move towards the frame base combination piece 1; the sliding plate 27 drives the cradle subassembly 2 to move towards the frame base combining piece 1 in the moving process, and finally one end part of the cradle subassembly 2 is inserted into the frame base combining piece 1 to finish the assembling process to form an assembled workpiece.
After the cradle sub-assembly 2 and the frame base combination piece 1 are assembled, the pin checking cylinder 41 on the pin checking mechanism 10 drives the verifying pin 45 to move downwards for a certain distance through the lifting sliding seat 42 and then reset, if the verifying pin 45 can be inserted into the assembly hole of the assembled workpiece, the cradle sub-assembly 2 and the frame base combination piece 1 are proved to be qualified, otherwise, the assembly is not qualified.
If the combined assembly of the cradle sub-assembly 2 and the cradle seat combining piece 1 is unqualified, the cradle sub-assembly 2 and the cradle seat combining piece are required to be manually adjusted to be in a qualified state; the indexing disk 6 is then rotated through a station to rotate the workpiece holder 7 with the conforming assembled workpiece into correspondence with the press pin mechanism 11.
When the work holder 7 with the qualified combined work is rotated to correspond to the pin pressing mechanism 11, the vibration feeder 64 in the pin feeder 63 of the pin pressing mechanism 11 acts to output the cylindrical pins 3 in a uniform posture and enters the inside of the receiving hole 52 of the guide plate 49 under the guide of the hose. At this time, the blanking hole 53 of the sliding plate 51 corresponds to the receiving hole 52, the cylindrical pin 3 enters into the blanking hole 53 under the action of gravity, and the elastic plunger 54 clamps and limits the cylindrical pin 3 in the blanking hole 53.
After the above process is completed, when the sliding cylinder 50 of the pin feeder 63 drives the sliding plate 51 to move to the outer position, the blanking hole 53 provided with the cylindrical pin 3 and the extrusion pin 66 are arranged in opposite directions (see fig. 31 of the specification), and the lower end of the cylindrical pin 3 corresponds to the assembly hole of the combined workpiece. Then the pressing cylinder 65 of the pin pressing mechanism 11 drives the pressing pin 66 to move downwards; the extrusion pin 66 moves downwards to enable the extrusion cylindrical pin 3 to enter an assembly hole of the combined workpiece; in the process of downward moving of the cylindrical pin 3, the press-fit workpiece is firstly extruded to drive the floating plate 16 to move downward together; when the supporting sleeve 68 on the floating plate 16 is in contact with the bearing column 67, under the supporting action of the bearing column 67, the combined workpiece and the floating plate 16 stop moving downwards, and then the cylindrical pin 3 enters the inside of the assembly hole of the combined workpiece under the pressure action of the extrusion pin 66 to complete the pin pressing process of the cylindrical pin; in the pin pressing process, the cylindrical pin 3 enters the assembly hole, and the cylindrical pin 3 presses the support shaft 24 through the positioning pin 25 to be inserted into the avoidance hole 69, so that the purpose of finishing press fitting by relatively moving the cylindrical pin 3 and the workpiece is achieved.
After the pin pressing of the cylindrical pin 3 is finished, the pressing cylinder 65 drives the pressing pin 66 to reset, and the floating plate 16 is reset under the action of the elastic force of the reset spring 17; the sliding cylinder 50 of the pin feeder 63 drives the sliding plate 51 to reset, and the pin pressing process is completed by the pin pressing mechanism 11.
After the pin pressing mechanism 11 completes the pin pressing process, the index plate 6 rotates one station, and the assembled workpiece with the pin pressed at the moment rotates along with the workpiece clamp 7 to correspond to the riveting mechanism 12 corresponding to the pin pressing mechanism 11. At this time, the cylindrical pin 3 on the combined workpiece and the press riveting seat 55 are arranged in opposite directions; the clinching cylinder 56 then drives the clinching head 57 downward. During the downward moving process of the press rivet 57, the positioning pin 25 and the support shaft 24 are extruded through the cylindrical pin 3, and finally collide with the ejector rod 58 along with the support shaft 24; after the ejector rod 58 abuts against the support shaft 24, the rivet pressing head 57 continues to move downwards, and at the moment, the cylindrical pin 3 completes the rivet pressing work under the extrusion of the positioning pin 25 and the rivet pressing head 57. The rivet 57 is then reset and the floating plate 16 on the workpiece holder 7 is reset.
After the pin pressing mechanism 11 completes the press riveting work, the index plate 6 rotates a station, the workpiece which completes the press riveting at the moment rotates together with the workpiece clamp 7 to correspond to the blanking mechanism 13, then the extrusion rod 31 is reset, the combined part pressing plate 22 and the sub-assembly pressing plate 29 loosen the workpiece, then the traversing slide seat 60 on the blanking mechanism 13 moves to the upper part of the workpiece, the blanking cylinder 61 adsorbs and fixes the workpiece through the material sucking disc 62, and then the blanking cylinder 61, the material sucking disc 62 and the traversing slide seat 60 are matched with each other to move the workpiece to a specified position.
