Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-3 As shown in the figure, this utility model embodiment proposes an automatic tightening mechanism for valve seat gaskets, comprising:

[0022] The fixed disk 2 can be mounted on a bracket, thus providing stable support for the fixed disk 2. A rotating disk 1 is rotatably connected to the fixed disk 2. A cam divider 5 is located below the rotating disk 1. The cam divider 5 is also called an intermittent divider, which is existing technology and can realize the intermittent rotation of the rotating disk 1. The cam divider 5 is connected to the rotating disk 1. Multiple sensors 4 are installed on the fixed disk 2 through the cam divider 5. A tooling 3 that cooperates with the fixed disk 2 is installed on the rotating disk 1. The sensors 4 are used to detect whether there is a product on the tooling 3.

[0023] To ensure the stability of the rotating disk 1 after it stops, a stop mechanism is also included. The stop mechanism includes a support cylinder 6 located below the rotating disk 1. A stop block is fixed at the output end of the support cylinder 6. A stop pin 8 that cooperates with the stop block is fixed at the bottom of the rotating disk 1. The number and position of the stop pins 8 are set in accordance with the tooling 3. The support cylinder 6 (which is pneumatic) drives the stop block to move upward and abut against the stop pin 8, which can position the rotating disk 1.

[0024] Tightening assembly; the tightening assembly includes a fixed bracket 7 located on one side of the fixed plate 2, a tightening gun 13 that can move up and down is mounted on the fixed bracket 7, a cylinder 9 is mounted on the fixed bracket 7, the output end of the cylinder 9 is fixed to the mounting plate 12, and the tightening gun 13 is mounted on the mounting plate 12. The tightening gun 13 is prior art and can be purchased from the market, such as a tightening gun with model number QST42-50CT-T50-L134-H13.

[0025] The output end of the tightening gun 13 is equipped with a mounting base 14, and a tightening head 15 is mounted on the mounting base 14. A guide rail 10 is mounted on the fixed bracket 7, and a slider connecting plate 11 is slidably connected to the guide rail 10. The mounting plate 12 is fixed on the slider connecting plate 11, which ensures that the mounting plate 12 moves stably up and down. A limit plate is fixed on the fixed bracket 7, and a buffer and anti-collision screws are installed on the limit plate to cooperate with the mounting plate 12. The buffer can buffer the downward movement of the mounting plate 12, and the anti-collision screws can limit the downward movement of the mounting plate 12 to avoid excessive downward movement and collision between the tightening head 15 and the tooling 3.

[0026] In actual use: When the product is placed on fixture 3, after sensor 4 on fixed plate 2 detects the product on fixture 3, support cylinder 6 extends and presses against stop pin 8 under rotating plate 1. Cylinder 9 extends and drives tightening gun 13 to move down. At the same time, tightening gun 13 drives mounting base 14 to rotate. Mounting base 14 drives tightening head 15 to rotate. When it contacts the product, the boss on tightening head 15 inserts into the product groove and tightens valve seat gasket with tightening gun 13. Cylinder 9 retracts and drives tightening gun 13 to move up. Support cylinder 6 retracts and cam divider 5 drives rotating plate to rotate one station to start the next cycle.

[0027] In summary, this utility model can automatically tighten valve seat gaskets, is simple to operate, highly efficient, saves time, and has promotional significance. It reduces the workload of workers and greatly improves efficiency and quality.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
