DETAILED DESCRIPTION

[0029] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0030] Embodiment 1: A differential assembly line for parts assembly, such as Figure 1-Figure 6As shown, it includes a conveyor 1, a shell 2, a fixed plate 3, an electric drive wheel 4, an assembly base 5, a stopping mechanism and a lifting mechanism. Several shells 2 are arranged between the two conveyors 1. A fixed plate 3 is installed on each shell 2. Several electric drive wheels 4 are evenly spaced on both sides of each shell 2. An assembly base 5 is placed on the fixed plate 3. The bottom of the assembly base 5 is in contact with the several electric drive wheels 4. A stopping mechanism is arranged in each shell 2, and the stopping mechanism is used to stop the assembly base 5. A lifting mechanism is arranged in one of the shells 2, and the lifting mechanism is used to lift the assembly base 5 to separate the assembly base 5 from the electric drive wheel 4.

[0031] The stopping mechanism includes a stopping cylinder 61, a stopping wheel 62 and a release button 63. A stopping cylinder 61 is installed in each shell 2 by bolts, and a stopping wheel 62 is installed on the telescopic rod of each stopping cylinder 61. A hole is opened on each fixed plate 3, and the stopping wheel 62 is located directly below the hole. A release button 63 is installed on one side of each shell 2, and each release button 63 is electrically connected to each stopping cylinder 61.

[0032] The lifting mechanism includes a mounting frame 71, a guide frame 72, a lifting frame 73, a lifting cylinder 74, a vertical rod 741 and a contact plate 75, wherein a mounting frame 71 is provided in one of the housings 2, and two guide frames 72 are slidably provided on the mounting frame 71, and the guide frames 72 will slide up and down along the mounting frame 71, and the two guide frames 72 are symmetrically arranged, and a lifting frame 73 is installed between the two guide frames 72, and an opening is opened on one of the fixing plates 3, and the lifting frame 73 is located directly below the opening, and a lifting cylinder 74 is installed in the middle part of the mounting frame 71 by bolts, and a vertical rod 741 is installed on the telescopic rod of the lifting cylinder 74 through a coupling, and a contact plate 75 is installed at one end of the vertical rod 741, and the contact plate 75 is located directly below the lifting frame 73.

[0033] When assembling parts, several workers first take up their positions at corresponding workstations. The workers power on the entire device, and the conveyor 1, the electric drive wheel 4 and the stop cylinder 61 all start to start. The telescopic rod of each stop cylinder 61 will extend, and each stop cylinder 61 will drive the stop wheel 62 to extend out from the hole on the fixed plate 3. The position of the top of each stop wheel 62 is higher than the position of the top of each fixed plate 3. The conveyor 1 transports the assembly base 5 to one of the fixed plates 3 on one side, and the bottom of the assembly base 5 contacts the electric drive wheels 4 on both sides. Under the action of the electric drive wheels 4, the assembly base 5 moves along the electric drive wheels 4. When one side of the assembly base 5 contacts one of the stop wheels 62, the assembly base 5 will be intercepted there. When the parts are assembled, the worker presses one of the release buttons 63, and the telescopic rod of one of the stop cylinders 61 is shortened, and the telescopic rod of the stop cylinder 61 drives the stop wheel 62 to move downward. After the stop wheel 62 moves down from the hole on the fixing plate 3 to the bottom of the fixing plate 3, the assembly base 5 is driven to move by the electric drive wheel 4. After the assembly base 5 leaves this station, the worker releases the release button 63 of this station, and the stop cylinder 61 drives the stop wheel 62 to extend out from the hole on the fixing plate 3. This is repeated to realize differential assembly of parts. When the parts are assembled for several steps, the last step requires the worker to use rubber The rubber hammer is used to knock on each assembled part for tightening operation. The worker controls the telescopic rod of the jacking cylinder 74 to extend. The telescopic rod of the jacking cylinder 74 drives the vertical rod 741 and the contact plate 75 to move upward. After the contact plate 75 moves upward and contacts the top of the jacking frame 73, the contact plate 75 drives the jacking frame 73 and the guide frame 72 to move upward. The jacking frame 73 drives the assembly base 5 on which the parts assembled in several steps are placed to move upward. The assembly base 5 on which the parts assembled in several steps are placed will be separated from the electric drive wheels 4 on both sides. The worker can use the rubber hammer to knock on the assembled parts for tightening operation, thereby avoiding the vibration of the knocking to be transmitted to the electric drive wheel 4 through the assembly base 5, protecting the electric drive wheel 4 from damage, and also avoiding the knocking During the beating, the assembly base 5 slides on the electric drive wheel 4, so that the assembly base 5 on which the parts assembled in several steps are placed is more stable, and the efficiency of the workers' beating is improved. After the fastening operation of the assembled parts is completed, the worker controls the telescopic rod of the jacking cylinder 74 to shorten, and the telescopic rod of the jacking cylinder 74 drives the vertical rod 741 and the contact plate 75 to move downward. Under the action of gravity, the jacking frame 73, the guide frame 72 and the assembly base 5 will move downward. After the jacking frame 73, the guide frame 72 and the assembly base 5 move downward for a certain distance, the jacking frame 73 and the guide frame 72 will stay at the installation top, and the assembly base 5 on which the parts assembled in several steps are placed will contact the electric drive wheel 4, and the jacking frame 73 will be separated from the assembly base 5 on which the parts assembled in several steps are assembled;By contacting one side of the assembly base 5 with one of the stop wheels 62, the assembly base 5 will be stopped at the position of one of the stop wheels 62, and the worker can assemble the parts on the assembly base 5 accordingly. After the parts are assembled accordingly, the worker releases the release button 63 of this station, and the stop cylinder 61 drives the stop wheel 62 to extend from the hole on the fixed plate 3. This is repeated to achieve differential assembly of parts. The lifting frame 73 drives the assembly base 5 on which the parts assembled in several steps are placed to move upward. The worker knocks the assembled parts to tighten them, thereby preventing the vibration of the knocking from being transmitted to the electric drive wheel 4 through the assembly base 5, protecting the electric drive wheel 4 from damage, and also preventing the assembly base 5 from sliding on the electric drive wheel 4 during knocking, making the assembly base 5 on which the parts assembled in several steps are placed more stable, and improving the knocking efficiency of the workers. ;

[0034] Embodiment 2: Based on embodiment 1, Figure 7-Figure 9 As shown, it also includes a locking mechanism, which is arranged on the mounting frame 71 and the contact plate 75. The locking mechanism is used to lock the lifting frame 73 after it rises. The locking mechanism includes a sliding frame 82, a locking frame 83, a reset spring 84 and a driving frame 85. A locking groove 81 is respectively opened on the side where the two guide frames 72 are close to each other. Two sliding frames 82 are slidably arranged on the mounting frame 71. The sliding frames 82 will slide horizontally along the mounting frame 71. The two sliding frames 82 are symmetrically arranged. A locking frame 83 is slidably provided on the side where the two sliding frames 82 are away from each other. Two reset springs 84 are arranged between the locking frame 83 and the sliding frame 82. A driving frame 85 is installed on the vertical rod 741.

[0035] The driving frame 85 consists of two inclined parts and two vertical parts, and the two sliding frames 82 are respectively located in the two inclined parts of the driving frame 85.

[0036] When the vertical rod 741 drives the driving frame 85 to move upward, the two inclined parts of the driving frame 85 drive the two sliding frames 82, the clamping frame 83 and the return spring 84 to move away from each other. After the two clamping frames 83 contact the two guide frames 72, the return spring 84 is stretched accordingly. When the two sliding frames 82 are located at the two vertical parts of the driving frame 85, the contact plate 75 just contacts the top of the lifting frame 73. The contact plate 75 drives the lifting frame 73, the guide frame 72 and the clamping slot 81 to move upward, and the two sides When the card slot 81 moves upward to the card frame 83, under the action of the return spring 84, the two card frames 83 will move away from each other, and the two card frames 83 will be stuck in the card slots 81 on both sides; the vertical rod 741 drives the driving frame 85 and the contact plate 75 to move downward, and after the two inclined parts of the driving frame 85 contact the two sliding frames 82, the two sliding frames 82, the card frame 83 and the return spring 84 move in a direction close to each other, and the card frame 83 will be separated from the card slot 81, and the frame 83 will be lifted up under the action of gravity. The two inclined parts of the driving frame 85 will drive the two sliding frames 82, the clamping frame 83 and the return spring 84 to move away from each other. After the two clamping frames 83 contact the two guide frames 72, the return spring 84 is stretched accordingly. When the clamping grooves 81 on both sides move upward to the clamping frames 83, under the action of the return spring 84, the two clamping frames 83 will move in the direction away from each other. The two clamping frames 83 will be clamped into the clamping grooves 81 on both sides. The two clamping frames 83 cooperate with the clamping grooves 81 on both sides, so that the guide frame 72 and the lifting frame 73 can be clamped, and then the position of the lifting frame 73 can be fixed. When the worker knocks and tightens the assembled parts, the vibration of the knocking can be reduced and transmitted to the lifting cylinder 74 through the assembly base 5, so that the lifting cylinder 74 can be protected. At the same time, the lifting frame 73 can be made more stable after rising, which is more convenient for the operator to knock and tighten the parts, thereby further improving the efficiency of parts assembly.

[0037] Embodiment 3: Based on embodiment 2, Figure 8-Figure 13 As shown, it also includes an adsorption mechanism, which is arranged on the lifting frame 73 and the contact plate 75. The adsorption mechanism is used to adsorb the assembly base 5. The adsorption mechanism includes a cylinder body 91, a piston 92, a through pipe 93, an air pipe 94 and a suction cup 95. A cylinder body 91 is installed on the top of the lifting frame 73, and a piston 92 is installed on the contact plate 75. The piston 92 is located in the cylinder body 91 and slides up and down along the cylinder body 91. A through pipe 93 is installed on the top of the lifting frame 73, and the through pipe 93 is connected with the cylinder body 91. Four air pipes 94 are installed at the lower part of the cylinder body 91, and the cylinder body 91 is connected with the air pipe 94. A suction cup 95 is installed on the other end of the four air pipes 94. The four suction cups 95 are all located on the lifting frame 73, and the suction cups 95 are made of rubber.

[0038] It also includes a limiting mechanism, which is arranged on the mounting frame 71 and the lifting frame 73. The limiting mechanism is used to limit the assembly base 5. The limiting mechanism includes a mounting seat 101, a rotating shaft 102, a limiting frame 103, a gear 104 and a fixed rack 105. One side of the lifting frame 73 is equipped with two mounting seats 101 by bolts, a rotating shaft 102 is rotatably provided between the two mounting seats 101 through a bearing, two limiting frames 103 are installed on the rotating shaft 102, and the limiting frames 103 are used to limit the assembly base 5. A gear 104 is respectively installed at both ends of the rotating shaft 102 in a key connection manner, and two fixed racks 105 are installed on one side of the mounting frame 71 by bolts. The two fixed racks 105 are meshed with the two gears 104.

[0039] A rubber pad 11 is also included, and a rubber pad 11 is installed on each of the two limiting frames 103 .

[0040] When the lifting frame 73 moves upward to lift the assembly base 5, the bottom of the assembly base 5 will be in close contact with the four suction cups 95, and the suction cups 95 are connected to the cylinder 91 through the air pipe 94. The vertical rod 741 moves upward to drive the piston 92 to move upward in the cylinder 91, and the gas on the upper part of the piston 92 is discharged through the through pipe 93. The gas density at the lower part of the piston 92 and the lower part of the cylinder 91 gradually decreases. Under the action of atmospheric pressure, the air pipe 94 and the suction cups 95 can adsorb the bottom of the assembly base 5; the vertical rod 741 moves downward to drive the piston 92 to move downward in the cylinder 91 through the through pipe 93. The external gas can be sucked into the cylinder 91, and the gas density at the bottom of the piston 92 and the lower part of the cylinder 91 gradually returns to normal, and the suction cup 95 no longer adsorbs the bottom of the assembly base 5; the piston 92 moves up and down, so that the gas density at the lower part of the cylinder 91 gradually decreases, and the suction cup 95 can adsorb the bottom of the assembly base 5 under the action of atmospheric pressure, and then fix the assembly base 5, so that the assembly base 5 is more stable after being lifted up by the lifting frame 73, and it is more convenient for the operator to knock and tighten the parts, thereby further improving the efficiency of part assembly.

[0041] When the lifting frame 73 moves upward, it drives the mounting seat 101, the rotating shaft 102, the limiting frame 103 and the gear 104 to move upward. Under the action of the fixed rack 105, the gear 104 will rotate. The rotation of the gear 104 drives the rotating shaft 102 to rotate. The rotation of the rotating shaft 102 drives the limiting frame 103 to rotate. The rotation of the limiting frame 103 can press down one side of the assembly base 5 placed on the lifting frame 73, so as to further fix the assembly base 5; when the lifting frame 73 moves downward, it drives the mounting seat 101, the rotating shaft 102, the limiting frame 103 and the gear 104 to move downward. Under the action of the fixed rack 105, the gear 104 will rotate in the opposite direction. The reverse rotation of the gear 104 drives the rotating shaft 102 rotates in the opposite direction, and the reverse rotation of the rotating shaft 102 drives the limiting frame 103 to rotate in the opposite direction. The reverse rotation of the limiting frame 103 can loosen the assembly base 5 placed on the lifting frame 73; the fixed rack 105 is meshed with the gear 104, and the gear 104 moves along the fixed rack 105, and the gear 104 rotates. The rotation of the gear 104 drives the rotating shaft 102 to rotate, and the rotation of the rotating shaft 102 drives the limiting frame 103 to rotate. The rotation of the limiting frame 103 can press down one side of the assembly base 5 placed on the lifting frame 73, so that the assembly base 5 is more stable after being lifted by the lifting frame 73, and it is more convenient for the operator to knock the parts for tightening operations, thereby further improving the efficiency of parts assembly.

[0042] When the limiting frame 103 swings to press the assembly base 5, the rubber pad 11 can provide buffer protection for the assembly base 5, while also increasing the friction force, so that the assembly base 5 is fixed more stably.
