Description

Technical Field

[0001] The invention belongs to the technical field of shock absorber assembly, in particular to a constant torque assembly device for a shock absorber spring nut. Background Art

[0002] At present, shock absorbers are mainly used to suppress the shock when the spring rebounds after absorbing shock and the impact from the road surface. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jumping. If the shock absorber is too soft, the car body will jump up and down. If the shock absorber is too hard, it will bring too much resistance and hinder the normal operation of the spring. In addition, when installing the spring of the existing shock absorber, if the nut specification that is not suitable for the equipment is mistakenly used, uneven force will be applied when tightening the nut, which will lead to assembly difficulties and abnormal wear and deformation of the installation part, thereby affecting the life of the shock absorber and other related components.

[0032] It should be noted that in the original text, "交错设置" is translated as "交错设置" in the Chinese part, which may be a typo. It is guessed that it should be "交错设置" (staggered arrangement). The above translation is based on the text provided. If there are any inaccuracies, please refer to the original intention for correction.As an embodiment of the present invention, a hole with the same shape and size as the inner tube of the telescopic rod 1 431 is opened in the middle of the nut box 456, and an electromagnet is arranged inside the nut box 456. A magnet is arranged at one end of the telescopic rod 2 4562 away from the fixed plate 457, and the magnetic force of the magnet on the telescopic rod 2 4562 is attracted to the magnetic force of the disc magnet block 54.

[0033] Specific working principle:

[0034] First, if Figure 2-6 As shown, the staff places the shock absorbing device 3 on the fixing device 2, and puts all the nuts into the storage box 455 at one time, and the staff does not need to put the nuts on the screws on the shock absorbing device 3 one by one; at this time, the double-headed motor 41 is started to drive the bevel gear 1 42 and the bevel gear 3 44 to rotate, and drive the bevel gear 2 43 and the bevel gear 4 45 to rotate synchronously, and the bevel gear 4 45 drives the cylinder 1 451 to rotate. Since the inclined surface of the cylinder 2 452 and the cylinder 1 451 are perpendicularly arranged and located at the end point of the inclined surface, and because the cylinder 3 453 is slidably connected in the square groove of the cylinder 4 454, when the inclined surface on the cylinder 1 451 rotates to face the cylinder 4 454, the cylinder 3 453 slides toward the bottom of the cylinder 4 454, and at this time, the cylinder 2 452 moves toward the cylinder When the inclined surface on the cylinder 1 451 rotates to face away from the cylinder 454, the cylinder 3 453 slides toward the top of the cylinder 454 to support the cylinder 2 452. At this time, the cylinder 2 452 tilts toward the direction of the block 51 and drives the storage box 455 to tilt in the same direction. During the tilting process of the storage box 455, the nut inside moves back and forth and is stuck in the nut opening 4561. If the inner diameter is the same as that of the telescopic rod 2 4562, it will move downward along the nut opening 4561. If they are different, they will slide through the nut opening 4561, so that nuts of different sizes enter the nut boxes 456 of corresponding sizes, thereby distinguishing nuts of different sizes and reducing the workload of staff.

[0035] Then, if Figure 4-6 As shown, when the nut enters the nut mouth 4561 and encounters the first baffle 4563 during the falling process, if the edge is exactly parallel to the baffle 4563, it will slide down directly; if the edge is not parallel to the baffle 4563, it will shake in the nut mouth 4561 during the shaking of the storage box 455, and look for the edge parallel to the first baffle 4563. When it finds the edge, it continues to fall downward and smoothly passes through the second baffle 4563. The second baffle 4563 fixes the nut to prevent the nut from changing shape due to continued shaking. At this time, each edge of the nut and the nut baffle 4464 are parallel, and because the size is exactly the same, the nut will not continue to slide downward, which is convenient for subsequent nut installation.

[0036] Then, if Figure 4-7 As shown, the motor 52 is started to drive the telescopic connecting rod 53 to rotate toward the storage box 455, and the electromagnet in the nut box 456 of the same size as the nut of the shock absorbing device 3 is started. The electromagnet is energized and emits a magnetic force in a direction different from that of the disc magnet 54, so that the disc magnet 54 is attracted by the nut box 456 of the started electromagnet and extends in that direction. Since the disc magnet 54 is provided with an inclined surface, it is convenient for the disc magnet 54 to pass through the edge of the storage box 455 to reach the upper part of the nut box 456 that emits magnetic force. 6 senses the magnetic force of the disk magnet 54 and moves toward the disk magnet 54, and the telescopic rod 4562 is also attracted by the magnetic force of the disk magnet 54 and connected to the disk magnet 54. At this time, the motor 52 rotates toward the shock absorber 3, driving the nut box 456 to move toward the shock absorber 3, and aligning the nut mouth 4561 with the screw on the shock absorber 3. At this time, the nut box 456 is stuck on the screw, and the motor 52 continues to rotate to bring the disk magnet 54 away from the nut box 456. The magnetic force of the nut box 456 attracts the telescopic rod 456. The magnetic block on the rod 1 431 makes the inner tube of the telescopic rod 1 431 extend and stretch the spring 432, and at the same time, it is stuck in the round hole in the middle of the nut box 456. At this time, the double-headed motor 41 is still rotating, and drives the bevel gear 2 43 to rotate, and the bevel gear 2 43 drives the gear 1 433 to rotate, and at the same time the gear 2 434 follows the rotation, and the nut in the nut box 456 of the gear 2 434 rotates smoothly and synchronously, and is tightened with the screws on the shock absorbing device 3, which reduces the workload of the staff and does not need the staff to tighten each one by one Tighten the nuts and ensure that each nut can be tightened; after tightening, close the electromagnet in the nut box 456, and the spring 432 pulls the inner tube of the telescopic rod 431 back to separate the telescopic rod 431 from the nut box 456. At this time, the motor 52 drives the telescopic connecting rod 53 to rotate in the direction of the shock absorbing device 3, so that the disc magnet 54 fits with the nut box 456, and restarts the electromagnet in the nut box 456, so that the two are attracted to each other, and the telescopic connecting rod 53 drives the nut box 456 back to its original position to continue collecting nuts.

[0037] like Figure 4-6 As shown, it should be noted that four equally divided hard sheets are provided at the connection between the storage box 455 and the nut box 456. When the nut box 456 is separated from the storage box 455, the four equally divided hard sheets seal the round hole of the storage box 455 to prevent other nuts from falling.

[0038] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
