[0066] Furthermore, the gripper fixing plate 147 is provided with a 500S spindle mold positioning hole 155 and a 200S spindle mold positioning hole 156.

[0067] The workflow of this invention is as follows: First, place the housing 19 on the mobile platform 2, rotate the housing 19 by 90°, install the lower bearing, then rotate the housing 19 by 180°, install the gear and bearing, then rotate it by 180° again, install the upper bearing, then install the oil baffle ring, bushing, apply glue, install the through hole cover, bolt, labyrinth cover and spacer in sequence, then rotate it by 180° again, run it a second time, install the oil baffle ring, bushing, apply glue, install the through hole cover, bolt, labyrinth cover and spacer in sequence, then rotate it by 90° again, install the eccentric block, and finally unload the material after installation.

[0068] The working principle of this invention is as follows: The mobile worktable of this invention consists of three parts: a 360° mobile worktable, a 180° rotating worktable, and a flipping worktable, which can realize the fixing of the machine casing, 90° side flipping, 360° rotation, and overall movement along the track platform.

[0069] The 360° movable worktable consists of a first slewing support 13, an upper fixed plate, and a center-driven servo backlash-free reducer 22. The inner ring of the first slewing support 13 is fixed on the movable worktable. The center-driven servo backlash-free reducer 22 drives the upper fixed plate and the outer ring of the slewing support, thereby driving the tilting worktable and the vibrator housing to rotate 360°.

[0070] The frame platform 1 of this invention is made of steel plates welded together in a cross pattern to a length of 320mm. After the 460mm grid is completed and welded together to remove welding stress, the lower plane is machined as a reference, and then the corresponding positions on the upper plane are machined. The second guide rail 113 and rack 114 are installed. Each set of worktables is 4 meters long, 2460mm wide, and 763mm high. There are a total of six sets, and the two sets are connected by bolts. The guide rail joints and worktable joints are staggered. After the overall assembly of the worktable is completed, the overall straightness and flatness need to be corrected to ensure the straightness of the second guide rail 113 assembly and the assembly accuracy of the rack 114.

[0071] The workpiece housing 19 to be assembled is hoisted onto the moving platform 2. The inner ring of the first slewing support 13 is fixed to the moving platform 2. The central drive servo motor 17 drives the upper fixed plate and the outer ring of the first slewing support 13 to rotate the housing 19 360°. The second guide rail 113 and the rack 114 mesh, and the end is equipped with a servo backlash-free reducer 22, which drives the worktable to move linearly along the rack. The double-outlet hydraulic cylinder 21 drives the tilting support 15 and the housing 19 to achieve a 90° tilt. After tilting, the lower support of the housing 19 holds the lower side of the housing 19, thus fixing the housing 19 in the working position. The four-column three-beam hydraulic workstation 3 can drive the pressing mold to realize the pressing work of the bearing and the spindle. The four-column three-beam hydraulic workstation 3 is located on the lower crossbeam 25. The four corners are each fitted with a first guide post 26. A middle crossbeam 27 and an upper crossbeam 28 are sequentially installed on the first guide post 26 from bottom to top. The lower crossbeam 25 has guide post mounting holes at the four corners. These guide post holes must be machined during processing. The upper crossbeam 28 is a welded steel plate structure. After machining, it is assembled and fixed to the top of the first guide post 26, and four sets of hydraulic cylinders are mounted on it. The middle crossbeam 27 is also a welded steel plate structure. Its upper end is connected to the hydraulic cylinders, and its lower end is fitted with a pressing mold. Guide posts are fitted at the four corners. The middle crossbeam 27 is driven by hydraulic cylinders 29, moving up and down along the four guide posts. The hydraulic station connects to the four hydraulic cylinders, requiring the four sets of hydraulic cylinders to move synchronously. Multiple parallel T-slots 30 are machined on the lower surface of the middle crossbeam 27 to fix the pressing mold. It then moves to the oil baffle ring. The oil baffle ring is assembled on assembly unit 4. After the first screw jack 33 transports the oil baffle ring, the two first electric slides 35 move left and right to the appropriate positions, and the first gripper 38 transports the oil baffle ring to the vibrator to begin assembly. Next, the bushing is assembled. After the second screw jack 40 transports the bushing to the designated position, the two second electric slides 42 move left and right to the appropriate positions, and the second gripper 45 transports the bushing to the vibrator for assembly. Next, glue is applied. The up-down, left-right, and front-back positions of the glue gun 53 are adjusted by the third electric slide 48, the fourth electric slide 50, and the fifth electric slide 51. After the position is adjusted, the cylinder in the glue storage tank 52 squeezes the glue onto the glue gun 53 for application. Next, the through-hole cover is assembled. The third screw jack 5... After the through-hole cover is delivered, the two sixth electric slides 58 move left and right, and the third gripper 61 delivers the through-hole cover to the vibrator to begin assembly. Next, the labyrinth cover unit is assembled. After the fourth screw jack 64 delivers the labyrinth cover, the two seventh electric slides 66 move left and right to the appropriate position, and the fourth gripper 69 delivers the through-hole cover to the vibrator to begin assembly. Next, the spacer is assembled. After the fifth screw jack 72 delivers the spacer, the two eighth electric slides 74 move left and right to the appropriate position, and the fifth gripper 77 delivers the spacer to the vibrator to begin assembly. Next, the bolts are assembled. The automatic bolt feeder 82 delivers the bolts, and the two automatic bolt assembly and tightening robots 81 begin assembling the bolts under system control.Finally, the eccentric blocks are assembled. The support beam 111 is manually hoisted onto the eccentric block mounting plate. After the hydraulic cylinder fixing frame 109 is adjusted vertically as needed, the seventh screw jack 112 pushes the support beam 111 from the eccentric block mounting plate to the rotary support. After the rotary support rotates to the installation position, the two second guide columns 101 and the eccentric block support platform 103 are moved vertically and positioned. Then, the eccentric block rotary support 105 and the eccentric block rotary platform 106 push the support beam 111 to assemble it onto the main shaft, completing the eccentric block assembly. To avoid unilateral stress on the machine casing, both eccentric blocks must be assembled simultaneously to counteract each other's forces.
