Three-station assembly flipping mechanism and assembly method

Abstract

This invention discloses a three-station assembly flipping mechanism and assembly method. The worm gear reducer and rotary reducer control the 360° forward and reverse rotation of the three stations, enabling precise adjustment of the flange angle of the three-station housing. During housing cleaning, the angle can be adjusted to a suitable position for the human body based on the area to be cleaned, improving cleaning speed. When assembling the moving and stationary insulators, adjusting the three-station housing to an appropriate angle enables rapid assembly, conductor position correction, and avoids collisions and scratches between the conductor and housing during assembly, thereby improving assembly quality and efficiency. The worm gear reducer, ball screw, and box-type linear bearing control the vertical height adjustment of the three-station housing, allowing adjustment to a suitable position based on the human body's height, thus reducing fatigue.

Description

Technical Field

[0001] This invention belongs to the technical field of three-station assembly equipment, and in particular relates to a three-station assembly flipping mechanism and assembly method. Background Technology

[0002] The current assembly process for the three-station unit is as follows: 1. Cleaning the three-station housing: During the assembly process, the housing needs to be flipped over for cleaning; 2. Assemble the moving-side insulator onto the three-station housing; 3. Flip the housing to the correct position and assemble the stationary-side insulator onto the three-station housing; 4. After the stationary-side insulator is installed, flip the three-station unit so that the stationary side faces down, so that the phase spacing of the stationary conductor can be corrected using tooling; 5. Flip the housing to the correct position and assemble the grounding switch, operating mechanism, etc. onto the three-station housing.

[0003] The problems encountered in the three-station assembly process are as follows: the shell is flipped many times in the three-station process, and each time it is flipped, a crane is used to lift it to ensure safety. If it is flipped manually, it may cause bumps and scratches to the shell surface; the crane takes a long time, delaying the use of the crane in other processes; and relying on manual flipping is labor-intensive and poses significant safety hazards. Summary of the Invention

This invention effectively solves the above technical problems, improves product assembly quality and production efficiency, and reduces labor intensity and safety hazards. The technical solution of this invention is as follows:

The controller controls the forward and reverse rotation of the second worm gear reducer, thereby realizing 360° forward and reverse rotation of the three workstations. It also controls the forward and reverse rotation of the first worm gear reducer to realize the up and down lifting of the three workstations, so that the height of the three workstations can be adjusted to a suitable position to facilitate the assembly of the three workstations.

[0018] The present invention also provides a three-station assembly method, comprising the following steps:

[0019] a. Installation of the three-station housing: Rotate the housing fixing base to the appropriate position and fix the three-station housing on the housing fixing base;

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] The worm gear reducer and rotary reducer control the 360° forward and reverse rotation of the three-station housing, enabling precise adjustment of the flange angle of the housing. During cleaning, the angle can be adjusted to a comfortable position for the user, improving cleaning speed. When assembling the moving and stationary insulators, adjusting the housing to the appropriate angle allows for rapid assembly, conductor position correction, and avoids collisions and scratches between the conductors and housing during assembly, thus improving assembly quality and efficiency. The worm gear reducer, ball screw, and box-type linear bearing control the vertical height adjustment of the housing, allowing it to be positioned appropriately according to the user's height, thereby reducing fatigue.

[0029] The three-station assembly and flipping mechanism reduces the time the crane is used in cleaning the inside of the housing and assembling the moving and stationary insulators, thus allowing the crane to be used for other processes, improving overall production efficiency and reducing safety hazards.

[0049] Example 1: Three-station assembly flipping mechanism

[0050] like Figures 1-5 As shown, it includes a tilting platform support assembly 1, a worm gear reducer 5 mounted on the tilting platform support assembly 1, a geared motor 14 connected to the worm gear reducer 5, and a vertically mounted ball screw 6;

[0051] The worm gear reducer 5 and the geared motor 14 are mounted on the top of the tilting platform support assembly 1; the top of the ball screw 6 is connected to the first worm gear reducer 5, which provides driving force to the ball screw 6. The ball screw 6 is connected to the worm gear mounting plate assembly 3. Two guide shafts parallel to the ball screw 6 are provided on both sides of the tilting platform support assembly 1. Box-type linear bearings 12 are provided on both sides of the worm gear mounting plate assembly 3. The box-type linear bearings 12 cooperate with the guide shafts to provide guidance for the vertical lifting and lowering of the worm gear mounting plate assembly 3.

[0052] Specifically, the worm gear mounting plate assembly 3 includes a worm gear mounting plate body and a screw wheel mounting plate 301, a lead screw support welded assembly 302, and a reducer support 303 disposed on the worm gear mounting plate body.

[0053] The two sides of the screw wheel mounting plate assembly 3 are connected to the box-type linear bearing 12 by bolts through the screw wheel mounting plate, and the intermediate screw support assembly is connected to the ball screw 6. The ball screw 6 is connected to the worm gear reducer 5. The worm gear reducer 5 drives the ball screw 6 to rotate, so as to realize the up and down lifting of the worm wheel mounting plate assembly 3.

[0054] The housing mounting base 4 is mounted on the partition mounting plate 2; the partition mounting plate 2 is mounted on the connecting flange 11; the connecting flange 11 is mounted on the rotary reducer 10; the rotary reducer 10 is mounted on the worm gear mounting plate 301 of the worm gear mounting plate assembly 3 by screws.

[0055] A worm gear reducer 8 is installed on the reducer support 303. The worm gear reducer 8 drives the rotary reducer 10 to rotate through the rotary reducer shaft 7, thereby realizing the rotation of the housing fixing seat 4.

[0056] The second worm gear reducer 8 is disposed on the side of the tilting platform support assembly 1.

[0057] The partition mounting plate 2 is also provided with a shell tightening rope 13 for binding the shell tightening rope 13.

[0058] This structure uses a second worm gear reducer 8 and a rotary reducer 10 to control the three-station rotation in both forward and reverse directions, enabling precise adjustment of the flange angle of the housing at each station.

The first worm gear reducer 5, ball screw 6, and box-type linear bearing 12 control the vertical height adjustment of the housing at each station, allowing it to be positioned appropriately according to the user's height, thereby reducing fatigue.
