[0056] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings of the specification and the specific implementation mode.

[0057] Embodiment:

[0058] As Figure 1 and Figure 2As shown, an embodiment of the present application discloses a pneumatic damper installation device for assisting in the assembly of a pneumatic damper, and its specific structure includes: a machine table 1, a frame 2, a pad 3, a positioning block 4, at least one pair of limit members 5, a support plate 6, at least one pair of limit members 7, a first lifting mechanism 8, a shell cover installation mechanism 9 and a second lifting mechanism 10.

[0059] The machine 1 is a box-like structure, the interior of which is used to install components, and the four corners of the bottom are provided with telescopically adjustable feet, so as to facilitate the equipment to remain level.

[0060] The frame 2 is installed on the machine platform 1 and is used to support the pad 3 described below.

[0061] The pad 3 is arranged horizontally and mounted on the frame 2, and the two are specifically connected by bolts, thereby ensuring the stability of the connection and facilitating disassembly and assembly.

[0062] The positioning block 4 is mounted on the bottom surface of the backing plate 3 , and the bottom surface has a positioning groove 401 ; the positioning groove 401 is matched with the protrusion on the top surface of the damping shell, and is used to position and fix the damping shell.

[0063] At least one pair of limiting members 5 is installed on the bottom surface of the pad 3, and each pair of limiting members 5 is arranged in an offset mirror image on both sides of the positioning block 4; the limiting member 5 can be engaged with the upper part of the cylinder body in the pneumatic damper, thereby playing a role in limiting and locking the pneumatic damper.

[0064] The support plate 6 is located between the machine platform 1 and the backing plate 3, and a docking through hole 601 is opened on the top surface; the docking through hole 601 is matched with the flange ring on the damping shell, thereby playing a positioning role.

[0065] At least one pair of limiting members 7 is installed on the top surface of the support plate 6 and corresponds to the limiting member 5; the limiting member 7 can be engaged with the lower half of the cylinder body in the pneumatic damper, thereby playing a role in limiting and locking the pneumatic damper.

[0066] It should be noted that the number of the limiting members 1 5 and the limiting members 2 7 corresponds to the number of the upper cylinders of the pneumatic damper, so if the upper cylinders of the pneumatic damper have a pair, the limiting members 1 5 and the limiting members 2 7 also have a pair accordingly.

[0067] The first lifting mechanism 8 is installed on the machine platform 1 and is in driving connection with the support plate 6, preferably fixedly connected with the side surface, for driving the support plate 6 to move up and down.

[0068] The shell cover mounting mechanism 9 can pass through the docking through hole 601 up and down, and is used to dock the shell cover with the flange ring on the damping shell.

[0069] Specifically, the shell cover installation mechanism 9 includes: a pillar 901, at least two positioning rods 902 and a lifting drive assembly 903. The pillar 901 is arranged above the machine 1, and a plug hole 9011 is opened on the top surface; at least two positioning rods 902 are arranged vertically and evenly arranged around the pillar 901; the lifting drive assembly 903 is installed on the outer periphery of the pillar 901 and is connected to the positioning rod 902 by transmission.

[0070] It should be noted that the insertion hole 9011 is used to insert the rotating shaft in the pneumatic damper, and the positioning rod 902 is inserted into the mounting hole on the shell cover to position the shell cover.

[0071] The second lifting mechanism 10 is installed on the machine platform 1 and is in driving connection with the support column 901 to drive the support column 901 to move up and down.

[0072] The technical solution of this application has the following working mode:

[0073] Step S1: Figure 3 As shown, the damping shell is placed on the top surface of the support plate 6, and the flange ring is inserted into the docking through hole 601, and the lower half of each pair of cylinder bodies is engaged with the limiting member 2 7 one by one, so that the damping shell is firmly placed and accurately positioned.

[0074] Step S2: Figure 4 As shown, the support plate 6 is driven to rise by the first lifting mechanism 8 until the protrusion on the top surface of the damping shell and the positioning groove 401 are inserted, and the upper parts of each pair of cylinder bodies are engaged with the limit members 5 one by one, so that the damping shell is clamped and fixed up and down.

[0075] Step S3: Figure 5 As shown, each positioning rod 902 is driven to rise to the top through the lifting drive assembly 903, and then the shell cover is placed on the top surface of the pillar 901, and the positioning rod 902 and the corresponding mounting holes on the shell cover are plugged in, so that the shell cover is firmly placed and accurately positioned, and the stepped hole on the shell cover is aligned with the plug hole 9011.

[0076] Step S4: Figure 6 As shown, bearings are respectively installed on the upper and lower ends of the rotating shaft, and then the rotating shaft is inserted into the stepped hole on the shell cover and connected with the socket 9011, so that the rotating shaft is installed and fixed.

[0077] Step S5: Figure 7 As shown, the shell cover installation mechanism 9 is driven to rise by the second lifting mechanism 10 until the shell cover extends into the docking through hole 601 and abuts against the flange ring, and at the same time, the positioning rod 902 is inserted into the corresponding installation hole on the flange ring, thereby completing the calibration of the shell cover and the flange ring.

[0078] Step S6: As Figure 8 shown, drive the support plate 6 to descend through the first lifting mechanism 8 until the support plate 6 is reset. At the same time, drive each positioning rod 902 to descend to the lowest point through the lifting drive assembly 903. At this time, the flange ring and the outer periphery of the shell cover are in an exposed state, and the positioning rod 902 will no longer be inserted into the corresponding mounting holes on the flange ring and the shell cover.

[0079] Step S7: As Figure 9 shown, bolt-connect the flange ring and the shell cover to complete the locking and fixing, and then it is completed.

[0080] Step S8: As Figure 10 shown, drive the shell cover mounting mechanism 9 to descend through the second lifting mechanism 10 until the shell cover mounting mechanism 9 is reset. During this process, the damping housing that has completed the shell cover installation will fall back onto the support plate 6 again and be stably placed. At this time, the damping housing can be taken away and the assembly of the next cycle can be carried out.

[0081] Through the above settings, it can assist in completing the installation of the pneumatic damper quickly and conveniently, with simple operation and low labor intensity, thereby greatly improving the production efficiency and reducing the production and manufacturing costs.

Then, they are driven by a plurality of evenly arranged third driving cylinders 9033, which can keep the force evenly distributed, thus reducing stress concentration and significantly enhancing the overall stability of the structure.
