[0049] (1) Feeding: Place the oil cylinder assembly on the feeding rail 8, and push the workpiece to the shaping station through the pushing mechanism 9 and the inductive push plate 11. After the position sensor senses that the workpiece is in place, shaping is performed. At the same time, the oiling device oils the assembly parts fed into the carrier rail 5;

[0050] (2) Shaping: The crank shaping assembly 19 lifts up the crank portion of the workpiece and is clamped and positioned by the positioning pin 27. Subsequently, the cylinder shaping assembly 18 lifts up the cylinder portion of the workpiece to make it warp upward, and the workpiece is bent into a V shape;

[0051] (3) Material taking: the material taking device 6 takes the shaped workpiece and places it on the orienting device 3;

[0052] (4) Orientation: The shaped workpiece is placed in the correction seat 34, the correction clamp 35 clamps the cylinder part, and the rotation mechanism 32 rotates the correction mechanism 33 and the workpiece as a whole by 90°, so that the workpiece as a whole is parallel to the carrier track 5;

[0054] (6) Assembly: the pressure rod 69 in the pressing mechanism 17 is pressed down to compress the spring in the assembly part, and then the clamping device 7 places the cylinder assembly on the assembly part for assembly;

[0055] (7) Positioning riveting: the positioning dot punching mechanism 60 moves forward, and its guide pin 65 extends out and is inserted into the riveting holes of the cylinder assembly and the assembly part to position the two. The feed head 55 accurately drives the rivet onto the guide pin 65, so that the rivet is inserted into the riveting hole and then riveted by the subsequent riveting device.

[0056] The present invention relates to a fully automatic hinge assembly production equipment for a cylinder assembly and an assembly method thereof. A carrier track 5 horizontally arranged in the middle of a frame 1 circulates and transports the carrier from the feed end to the discharge end in sequence. The carrier is loaded with workpieces for assembly with the cylinder assembly. Along the feeding direction of the carrier track 5, an oiling device, a feeding device 2, an orienting device 3 and a positioning device 4 are respectively installed on the frame 1 from the feed end to the discharge end of the carrier track 5. The oiling device and the feeding device 2 are respectively arranged on both sides of the feed end of the carrier track 5. The carrier is first sent to the oiling device through the carrier track 5. At this time, the oil nozzle on the oiling device moves downward, and the oiling operation is performed on the assembly part of the carrier through its oiling valve.

[0057] Furthermore, a cylinder assembly for assembling with the assembly parts on the carrier is manually placed on the feeding device 2. The cylinder assembly includes a crank portion and a cylinder portion that can be bent to each other. The cylinder assembly is first placed on the feeding rail 8 of the feeding device 2. The feeding rail 8 transports the cylinder assembly to the pushing mechanism 9 installed on the feeding rail 8. When the induction push plate 11 on the pushing mechanism 9 senses that the cylinder assembly is in place, the first drive 14 is started. At the same time, the blocking rod 30 located in front of the induction push plate 11 is driven by the fourth drive 29. The action of the fourth drive 29 causes the induction push plate 11 to withdraw from the feeding rail 8, so that the induction push plate 11 pushes the cylinder assembly at that position on the feeding rail 8 to the discharge port (shaping station) of the feeding rail 8. After pushing is completed, the induction push plate 11 returns to the starting position, and the blocking rod 30 is again extended into the feeding rail 8 by the action of the fourth drive 29, blocking the front of the induction push plate 11. At the same time, after the position sensor 12 located at the end of the discharge port of the feeding rail 8 senses the cylinder assembly, the shaping mechanism 10 arranged at the discharge port of the feeding rail 8 starts to work.

[0058] Furthermore, the air cylinder 22 arranged at a certain inclination angle below the feeding rail 8 is started, and the push block 23 is pushed upward at a certain inclination angle through its transmission shaft 24, and the crank part on the cylinder assembly is lifted by the push block 23. The third drive 26 is started to extend the positioning needle 27, and the crank part is clamped and positioned by the positioning needle 27. At the same time, the cylinder shaping assembly 18 lifts the top block 21 through the second drive 20, so that the cylinder part of the cylinder assembly is warped upward, so that the crank part and the cylinder part of the cylinder assembly form a V-shape with a certain angle to each other, and the picking device 6 clamps the entire shaped cylinder assembly through the picking head and moves it to the orienting device 3.

[0059] Furthermore, the picking device 6 places the shaped cylinder assembly on the orienting device 3 located on one side of the feeding device 2, and the cylinder assembly is placed in the correction mechanism 33. Specifically, the correction seat 34 has a precise positioning groove 36, and the crank part of the cylinder assembly is clamped in the positioning groove 36 to achieve further shaping, and the positioning groove 36 is connected to the negative pressure adsorption component 37, and the crank part is sucked by the negative pressure adsorption component 37, and the cylinder part is precisely corrected and positioned by the correction clamp 35. The rotating mechanism 32 is powered by the motor to rotate 90°, and the correction mechanism 33 is synchronously rotated with the rotation of the rotating mechanism 32, so that the cylinder assembly originally in a perpendicular relationship with the carrier track 5 is rotated to a position parallel to the carrier track 5, waiting for the clamping device 7 to pick up the material.

[0060] Furthermore, the sliding mechanism 39 on the clamping device 7 is started, the slider 42 slides along the slide rail 41, and drives the clamping mechanism 40 installed thereon to slide synchronously along the slide rail 41, so that the clamping mechanism 40 slides to the top of the correction seat 34 after the turn. At this time, the first lifting drive 45 pushes the connecting plate 44 from the mounting plate 43 to the correction seat 34. After reaching the maximum stroke, the second lifting drive 47 pushes the clamping jaw 46 toward the correction seat 34. At the same time, the correction clamp 35 releases the cylinder part, and the clamping jaw 46 clamps the cylinder assembly parallel to the carrier track 5. Subsequently, the clamping jaw 46 with the cylinder assembly is moved to the front of the positioning device 4 through the slider 42, and the cylinder assembly is transported to the top of the carrier track 5 of the carrier carrying the workpiece after oiling.

[0061] Further, when the clamping device 7 clamps the workpiece and moves to the front of the positioning device 4, the pressing mechanism 17 on the support frame 66 is started, the support frame 66 is integrally mounted above the carrier track 5 and fixedly mounted on the frame 1, the sliding seat 67 is installed on the support frame 66 at a certain angle, and the seventh drive 70 installed on the sliding seat 67 is started, and the guide block 68 arranged on the sliding seat 67 is pushed out in the direction of the carrier track 5 through the output shaft 71, so that the pressure rod 69 arranged at the bottom of the guide block 68 is pushed toward the carrier track 5. The guide mechanism 16 starts to start, and the bending arm 61 on the mounting platform 58 pushes the transmission block 62 toward the carrier track 5, and the transmission block 62 drives the positioning and dotting mechanism 60 to be pushed toward the carrier track 5. Specifically, the positioning and dotting mechanism 60 includes a positioning plate 63, a sixth drive 64 and a plurality of guide pins 65, wherein the positioning plate 63 is connected to the transmission block 62, and the transmission block 6 2, the positioning plate 63 slides along the guide rail on the mounting table 58 to the side of the carrier track 5, the sixth drive 64 is started, and the guide pin 65 is pushed into the carrier track 5, so that the guide pin 65 is respectively inserted into the riveting holes of the assembled crank part and the assembly part, so that the oil cylinder assembly and the assembly part are positioned with each other. Then, the material distribution assembly 48 on the rivet conveying mechanism 15 feeds the material, and its material tray 51 conveys the rivets to its material distribution rail 52 by vibration. The material distribution rail 52 rivets the rivets one at a time or multiple at a time according to the production requirements. The rivets are fed in two ways here. The rivets are fed to the feeding head 55 by the fan through the tube body connected to the dividing rail 52 and the feeding head 55. A guide assembly 50 is provided on one side of the feeding head 55. The rivets fed to the feeding head 55 are corrected by the correction block 57 of the guide assembly 50, and then the push rod 54 is pushed out by the fifth drive 56 located on the fixed seat 53, so that the push rod 54 can penetrate the corrected rivet in the feeding head 55 into the guide needle 65, so that the rivet can accurately enter the riveting hole of the positioned crank part and the assembly part that cooperate with each other.

[0062] Furthermore, the assembly part with the rivet installed in the crank part is transported by the carrier along the carrier track 5 to the riveting mechanism of the next processing unit of the positioning device 4, and the rivet is riveted by the riveting mechanism.
