[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please refer to the following: Figures 1 to 5The present invention will now describe a specific embodiment of an automatic installation device. This automatic installation device is used to install a gas spring 6 comprising an outer cylinder 61, an inner cylinder 62, and an end cap 63. It includes a frame 1, a clamping assembly 2, a limiting assembly 3, a pushing assembly 4, and a tightening assembly 5. The clamping assembly 2 is connected to both the frame 1 and the outer cylinder 61 to fix the outer cylinder 61; the limiting assembly 3 is connected to both the frame 1 and the inner cylinder 62 to fix the inner cylinder 62; the pushing assembly 4 is connected to the frame 1 to push the end cap 63 along the direction of the inner cylinder 62, with both the inner cylinder 62 and the end cap 63 coaxially arranged with the outer cylinder 61; and the tightening assembly 5 is connected to the end cap 63 to lock and fix the end cap 63 to the outer cylinder 61.

[0048] For ease of explanation, please refer to Figure 2 A rectangular coordinate system is established with any point in space as the origin, the setting direction of the clamping component 2 relative to the gas spring 6 as the Z-axis, the setting direction of the gas spring 6 as the Y-axis, and the straight line direction that is perpendicular to both the Y-axis and the Z-axis as the X-axis. The XY plane is a horizontal plane, the direction indicated on the horizontal plane is the horizontal direction, and the direction indicated by the Z-axis is the vertical direction.

[0049] Compared with the prior art, this automatic installation device is a device for automatically installing and tightening the end cap 63 of the gas spring 6, and is responsible for automatically completing the assembly of the end cap 63 of the gas spring 6. By setting up the clamping assembly 2 and the frame 1, the centers of the inner cylinder 62, outer cylinder 61, and end cap 63 are designed at the same height according to the size of the gas spring 6. After the device clamps all the parts of the gas spring 6, the inner cylinder 62, outer cylinder 61, and end cap 63 are automatically aligned. The end cap 63 is easier to install and easier to operate. Even inexperienced workers can operate and install it without easily damaging the end cap 63, thus effectively improving installation efficiency. The limiting assembly 3 pulls the inner cylinder 62 so that when the end cap 63 is rotated and tightened, the inner cylinder 62 will not retract to the bottom of the outer cylinder 61 due to friction. The end cap 63 is placed on the tightening assembly 5 and then placed on the pushing assembly 4. The pushing assembly 4 pushes the end cap 63 to the required position so that the external thread of the end cap 63 and the internal thread of the outer cylinder 61 maintain a certain gap and do not contact each other, ensuring that the thread teeth do not collide or deform, and ensuring installation quality. This device solves the problems of current technology, which requires operators to have high assembly experience, and is prone to scratching mating surfaces and damaging seals, which greatly affects assembly quality and efficiency.
