If the cradle subassembly 2 is placed incorrectly, the subassembly pressing plate 29 is actuated to separate the cradle subassembly 2, and the above-described actions are repeated after a new cradle subassembly 2 is placed, until the cradle subassembly 2 with the correct position is placed on the work holder 7, and then the actions are stopped.
The cradle subassembly 2 with the correct position is placed on the workpiece fixture 7, and after the cradle subassembly 2 is fixedly pressed by the subassembly pressing plate 29, the index plate 6 rotates for one station, and at the moment, the workpiece fixture 7 provided with the cradle subassembly 2 rotates to correspond to the feeding mechanism 9 along with the index plate 6. The feeding manipulator 35 on the feeding mechanism 9 then grips a housing joint 1 to be assembled from the supply line 34 by means of the gripping jaws 38 on the workpiece gripping head 36; then the cylinder on the workpiece chuck 36 drives the loading check pin 39 to move up and down, if the loading check pin 39 can be inserted into the assembly hole on the frame seat joint part 1, the clamping posture of the workpiece chuck 36 is correct, otherwise, the clamping posture is wrong. If the workpiece chuck 36 has an incorrect clamping posture, the workpiece chuck 36 places the clamped frame seat joint member 1 at another position, then clamps a new frame seat joint member 1 again, and then the loading check pin 39 acts to verify the clamping posture of the frame seat joint member 1. The operation is repeated until the workpiece chuck 36 clamps the frame seat combining piece 1 with the correct posture; then the feeding manipulator 35 places the frame seat combining piece 1 on the main bearing platform 18 and the auxiliary bearing platform 19 on the workpiece fixture 7 through the workpiece chuck 36, and at the moment, the frame seat combining piece 1 is inserted and connected with the positioning boss 32 on the auxiliary bearing platform 19 and is connected with the positioning pin 25 on the main bearing platform 18 in an inserting way; the frame seat joint 1 can be pressed and fixed on the main bearing platform 18 and the auxiliary bearing platform 19 by the joint pressing plate 22 under the matching of the pressing cylinder 20 and the rotating cylinder 21. At this time, the work holder 7 corresponding to the feeding mechanism 9 is fixedly provided with the frame base connector 1 and the cradle subassembly 2.
After the frame seat combining part 1 is fixed on the workpiece fixture 7 by the combining part pressing plate 22, the indexing disc 6 rotates for one station, and at the moment, the workpiece fixture 7 provided with the frame seat combining part 1 and the cradle subassembly 2 rotates to correspond to the pin checking mechanism 10 along with the indexing disc 6. Then, the cylinder on the work fixture 7 drives the action extrusion rod 31 to be inserted into the cradle subassembly 2, and then the positioning piece 4 in the cradle subassembly 2 is extruded to the assembling station.
The extrusion rod 31 is kept still after being actuated, and then the pushing cylinder 26 pushes the sliding plate 27 to move towards the frame seat combining piece 1; the sliding plate 27 drives the cradle subassembly 2 to move towards the cradle connector 1 during moving, and finally one end part of the cradle subassembly 2 is inserted into the cradle connector 1 to complete the assembling process to form the assembled workpiece.
After the cradle subassembly 2 and the frame seat combining part 1 are assembled, the pin testing cylinder 41 on the pin testing mechanism 10 drives the verification pin 45 to move downwards for a certain distance through the lifting slide seat 42 and then reset, if the verification pin 45 can be inserted into the assembling hole of the assembled workpiece, the cradle subassembly 2 and the frame seat combining part 1 are assembled in a qualified mode, and if not, the cradle subassembly 2 and the frame seat combining part 1 are assembled in an unqualified mode.
If the cradle sub-assembly 2 and the cradle combination part 1 are not qualified, the cradle sub-assembly and the cradle combination part need to be manually adjusted to be in a qualified state; the index plate 6 is then rotated by one station, so that the workpiece holder 7 with the accepted multi-piece workpiece is rotated to correspond to the pressure pin mechanism 11.
When the workpiece holder 7 with the acceptable multi-workpiece is rotated to correspond to the pin pressing mechanism 11, the vibrating loader 64 in the pin feeder 63 of the pin pressing mechanism 11 is operated to output the cylindrical pins 3 in a uniform posture and enter the inside of the material receiving hole 52 of the guide plate 49 under the guide of the hose. At the moment, the blanking hole 53 of the sliding plate 51 corresponds to the material receiving hole 52, the cylindrical pin 3 enters 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 processes are 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 is arranged opposite to the extrusion pin 66 (see the attached drawing 31 in the specification), and the lower end of the cylindrical pin 3 corresponds to the assembly hole of the assembled workpiece. Then the pressing cylinder 65 of the pin pressing mechanism 11 drives the extruding pin 66 to move downwards; the extrusion cylindrical pin 3 enters the assembly hole of the assembled workpiece in the downward moving process of the extrusion pin 66; in the process of moving the cylindrical pin 3 downwards, firstly, the combined workpiece is extruded to drive the combined workpiece to move downwards to move the floating plate 16; when the supporting sleeve 68 on the floating plate 16 is abutted against the bearing column 67, the combined workpiece and the floating plate 16 stop moving downwards under the supporting action of the bearing column 67, and then the cylindrical pin 3 enters the inner part of the combined workpiece assembling hole under the pressure action of the pressing pin 66 to complete the pin pressing process of the cylindrical pin; in the pin pressing process, in the process that the cylindrical pin 3 enters the assembling hole, the cylindrical pin 3 extrudes the supporting shaft 24 through the positioning pin 25 to enable the supporting shaft to be inserted into the avoiding hole 69, and therefore the purpose that the cylindrical pin 3 and a workpiece move relatively to complete press fitting is achieved.
After the cylindrical pin 3 finishes pressing the pin, the pressing cylinder 65 drives the extrusion pin 66 to reset, and the floating plate 16 resets under the action of the elastic force of the reset spring 17; the sliding cylinder 50 of the pin conveyor 63 drives the sliding plate 51 to reset, and the pin pressing mechanism 11 completes the pin pressing process.
After the pin pressing mechanism 11 completes the pin pressing process, the index plate 6 rotates by one station, and the assembled workpiece which completes the pin pressing at this time rotates to correspond to the riveting mechanism 12 corresponding to the pin pressing mechanism 11 along with the workpiece clamp 7. At the moment, the cylindrical pin 3 on the combined workpiece is arranged opposite to the pressure riveting seat 55; the squeeze riveting cylinder 56 then drives the squeeze riveting head 57 downward. The squeeze rivet head 57 extrudes the positioning pin 25 and the support shaft 24 through the cylindrical pin 3 in the downward moving process, and finally butts against the ejector rod 58 along with the support shaft 24; after the push rod 58 is abutted against the support shaft 24, the squeeze rivet head 57 continues to move downwards, and at the moment, the cylindrical pin 3 completes squeeze riveting work under the extrusion of the positioning pin 25 and the squeeze rivet head 57. The squeeze rivet head 57 is then reset and the floating plate 16 on the work holder 7 is reset.
After the press riveting work of the press pin mechanism 11 is completed, the index plate 6 rotates one station, the workpiece which is subjected to press riveting at the moment and the workpiece clamp 7 rotate together to correspond to the blanking mechanism 13, then the extrusion rod 31 resets, the combination piece pressing plate 22 and the sub-assembly pressing plate 29 loosen the workpiece, then the transverse sliding 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 suction plate 62, and then the blanking cylinder 61, the material suction plate 62 and the transverse sliding seat 60 are matched with each other to move the workpiece to a specified position.
