Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figures 1 to 11 As shown: An automatic assembly mechanism for Y-type sealing rings includes a feeding unit 1, an assembly unit 2, and a picking unit 3. The picking unit 3 is located on the right side of the feeding unit 1, and the assembly unit 2 is located in front of the feeding unit 1. The feeding unit 1 includes a vibratory feeder mounting base 11, a vibratory feeder 12, a linear vibrator 13, a toothed plate 14, and a material channel 15. The vibratory feeder 12 is connected to the vibratory feeder mounting base 11, and the material channel 15 is connected to the outlet of the vibratory feeder 12. The linear vibrator 13 is located at the bottom of the material channel 15 and is connected to the vibratory feeder mounting base 1. The free end of the material channel 15 is provided with a lifting tool insertion slot 16. The lifting tool 323 of the lifting mechanism 32 moves upward and passes through the lifting tool insertion slot 16 to lift the workpiece 4, facilitating the picking unit 3 to grip it. Figure 5 As shown, the toothed plate 14 has arc-shaped toothed grooves of different diameters on both sides, with each diameter corresponding to a different type of sealing ring. The arc-shaped toothed plate positions the workpiece. When replacing, the toothed plate is manually lifted and rotated 180° before being placed into the material outlet of the material channel. One toothed plate can accommodate two types of sealing rings. The vibratory feeder mounting base 11 is fixed on the ground, and the vibratory feeder 12 and the straight vibrator 13 are fixed above the vibratory feeder mounting base 11. The vibratory feeder outlet is connected to the straight vibrator material channel, and the toothed plate 14 is installed at the end of the material channel for limiting. The toothed plate 14 is connected to the straight vibrator outlet by spring bolts 17. The feeding unit enables automatic feeding of the vibratory feeder, automatic alignment of the sealing ring, and delivery of the material to the toothed limiting plate for positioning, awaiting material removal.

[0035] like Figure 6 As shown, the material handling unit 3 includes a material handling unit base 31, a lifting mechanism 32, a frame 33, a material handling mechanism 34, a transfer mechanism 35, and a lifting cylinder 36. The lifting mechanism 32 and the frame 33 are connected to the material handling unit base 31, the transfer mechanism 35 is connected to the top of the frame 33, the lifting cylinder 36 is connected to the transfer mechanism 35, and the material handling mechanism 34 is connected to the telescopic end of the lifting cylinder 36. Figure 8As shown, the lifting mechanism 32 includes a support 321, a lifting cylinder 322, and a lifting fixture 323. The bottom end of the support 321 is connected to the base 31 of the material handling unit, the lifting cylinder 322 is connected to the top plate of the support 321, and the lifting fixture 323 is connected to the telescopic end of the lifting cylinder 322. The base 31 of the material handling unit is fixed on the ground. The Y-shaped sealing ring is conveyed to the toothed plate 14 for limiting. The lifting mechanism lifts the workpiece 1, i.e., the sealing ring. The material handling mechanism descends through the lifting cylinder 36 to grab the sealing ring. Then, the lifting cylinder drives the material handling mechanism to rise, and the transfer mechanism 35 moves the material handling mechanism to the assembly station.

[0036] like Figure 9 , Figure 10 As shown, the material handling mechanism 34 includes a cylinder mounting base 341, a clamping mechanism 342, a rotary cylinder 343, and a knurled knob 344. The rotary cylinder 343 is connected to the cylinder mounting base 341, and the cylinder mounting base 341 is connected to the clamping mechanism 342 via the knurled knob 344. The lower part of the rotary cylinder 343 is connected to the clamping mechanism. The clamping mechanism includes a guide sleeve 3421, a spline bearing assembly 3422, a spherical gripper 3423, and an inner limiting ring 3424. The guide sleeve 3421 has an inner limiting ring 3424 inside, which is connected to the inner wall of the guide sleeve. The spline bearing assembly 3422 is connected to the inner wall of the guide sleeve, and the spherical gripper 3423 is located at the bottom of the spline bearing assembly. The inner limiting ring 3424 is positioned within the groove of the sealing ring for limiting its movement. The rotary cylinder 343 rotates, driving the spline bearing assembly 3422 to rotate, causing the spherical grippers to clamp the inner arc groove of the sealing ring, thus completing the workpiece gripping. During assembly, the guide sleeve first performs secondary positioning of the workpiece to ensure the coaxiality of the sealing ring and the mounting hole of the workpiece to be assembled. After the spherical grippers 3423 smoothly grip the sealing ring and enter, the rotary cylinder 343 actuates, the spherical grippers close, releasing the sealing ring, and then retract, completing the assembly of the seal. During production changeover, the knurled knob 344 is unscrewed to replace the sealing ring gripping mechanism, making operation convenient.

[0037] like Figure 7 As shown, the assembly unit 2 includes an assembly worktable 21, a pneumatic slide table 22, and an assembly fixture 23. The pneumatic slide table 22 is connected to the top wall of the assembly worktable 21, and the assembly fixture 23 is slidably connected to the pneumatic slide table 22. The assembly unit adopts a dual-station pneumatic slide table structure. One station of the dual-station pneumatic slide table performs automatic assembly, while the other station performs loading and unloading, alternating actions, resulting in high production efficiency.

[0038] The automatic assembly mechanism for Y-type sealing rings of this utility model adopts a structure including automatic feeding by a vibratory feeder, limiting by a toothed plate, lifting mechanism to lift the sealing ring, clamping mechanism to automatically clamp the sealing ring, transfer mechanism, and assembly station.
