Description

Technical Field

[0001] The invention relates to the technical field of automatic assembly equipment, and in particular to a pneumatic spring assembly device. Background Art

[0002] In the field of automated assembly, pneumatic springs are a common mechanical component widely used in various mechanical equipment. The assembly quality of pneumatic springs directly affects the performance and reliability of the final product, so the accuracy and efficiency of the assembly process are crucial. Traditional pneumatic spring assembly is mostly done manually or semi-automatically, which is not only inefficient but also difficult to ensure assembly accuracy and consistency. With the increase in production demand, traditional methods can no longer meet modern high-efficiency and high-precision production requirements.

[0003] In an existing pneumatic spring assembly technology, multiple assembly stations are arranged in sequence, and each station is responsible for different assembly tasks. Although this arrangement improves the assembly efficiency to a certain extent, there are still some shortcomings. For example, the loading and positioning process of the piston rod usually requires manual intervention, which not only increases the labor intensity, but also reduces the overall assembly speed and accuracy. In addition, the loading of the sealing ring is often not completed by a special mechanism 7, resulting in low efficiency of the sealing ring assembly and prone to poor assembly.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the invention

The transmission shaft of the shaft gear is threadedly connected to the mounting plate, and the mounting plate is also provided with multiple guide columns, and the guide columns are vertically fixed on the main frame.

[0008] The beneficial effects of the above embodiment are: the combination of the active gear ring and the first driving member provides stable and controllable rotation of the mounting disk, ensuring assembly accuracy, while the engagement of the shaft gear with the active gear ring and the use of the guide column further stabilize the operation of the mounting disk, making the assembly process smoother and more precise.

[0009] In one embodiment of the present invention, the sealing ring feeding mechanism includes a vibrating loader, a material distribution track and a loading bracket. The feed port and the discharge port of the material distribution track are respectively connected to the vibrating loader and the loading bracket. The loading bracket is located directly below the manipulator.

[0010] The beneficial effects of the above embodiment are: the vibrating loader and the material distribution track realize automatic sorting and precise feeding of the sealing rings, and the position of the loading bracket is adjusted to be directly below the robot arm, ensuring that the sealing rings can be accurately grasped and assembled by the robot arm.

[0012] The beneficial effect of the above embodiment is that the clamping block cooperates with the first slide rail and the second driving member, so that the manipulator has higher flexibility and accuracy when clamping and placing the sealing ring, can adapt to sealing rings of different sizes and shapes, and improves the applicability of the equipment.

[0013] In one embodiment of the present invention, it also includes a driving mechanism that can be lifted and lowered on the operating table, the driving mechanism includes a second slide rail and a third driving member, the sleeve clamp is arranged at the output end of the third driving member and can be movably arranged on the second slide rail, and the first slide rail and the second slide rail are arranged in parallel.

[0014] The beneficial effect of the above embodiment is that the second slide rail and the third drive member provide the sleeve clamp with precise vertical movement capability, so that the protective sleeve can better dock with the piston rod without interfering with the assembly process of the sealing ring.

[0015] In one embodiment of the present invention, it further comprises a material unloading mechanism disposed on the peripheral side of the mounting plate, and the material unloading mechanism is located on the lower station of the assembly mechanism.

[0016] The beneficial effect of the above embodiment is that the setting of the unloading mechanism automatically moves the product out of the workstation after assembly is completed, which not only improves production efficiency, but also reduces manual intervention and reduces possible errors and damages during operation.

[0017] As described above, the pneumatic spring assembly equipment of the present invention has the following beneficial effects: the mounting plate then rotates to deliver the spring to the piston rod feeding mechanism for feeding.

[0037] See also Figures 1 to 5 The present invention provides a pneumatic spring assembly device, which mainly includes a main frame 1, a mounting plate 2, a fixture 3, a piston rod feeding mechanism and an assembly mechanism. A plurality of the fixtures 3 are installed at intervals at the edge of the mounting plate 2 rotatably arranged on the main frame 1, and the fixtures 3 are used to fix the pneumatic spring to be assembled.

[0038] In order to achieve an efficient assembly process, this embodiment adopts the design of an active gear ring 8, a first driving member 9, a shaft gear 10 and a guide column 11.

[0039] While improving the assembly efficiency, this embodiment also focuses on the automation and accuracy of the assembly process. The sealing ring feeding mechanism includes a vibration feeder 12, a material distribution track 13 and a loading bracket 14. The vibration feeder 12 cooperates with the material distribution track 13 to achieve automatic sorting and accurate feeding of the sealing ring.

[0042] In summary, the pneumatic spring assembly equipment of the present invention then rotates the mounting plate 2 to deliver the spring to the piston rod loading mechanism for loading. Afterwards, the spring is sequentially transferred to three assembly stations, each of which completes specific steps; on the operating table 4, the piston rod is vertically clamped, and the protective sleeve 5 and the sealing ring are sleeved; the sealing ring is supplied by a special loading mechanism and accurately placed by the manipulator 7.
