Detailed Implementation

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] like Figure 1 - Figure 5 As shown, this application provides a filament tensioning device for diamond coating processing, including a filament support 1 and a filament contact post 101 disposed on the filament support 1. A tension spring 2 is disposed on the side wall of the filament support 1, and multiple sets of contact grooves 1011 are disposed on the top of the filament contact post 101.

[0027] Specifically, such as Figure 2 As shown, a fixing component 3 is provided between the filament bracket 1 and the tension spring 2. The fixing component 3 is used to fix the tension spring 2. The fixing component 3 includes a connector 301, which is fixedly connected to the end of the tension spring 2 and inserted into the inside of the filament bracket 1. A fixing component 303 is slidably connected inside the filament bracket 1 and inserted into the top of the connector 301. By setting the fixing component 3 between the filament bracket 1 and the tension spring 2, the tension spring 2 can be disassembled and assembled by moving the fixing component 303, which facilitates the quick replacement of the worn and loose tension spring 2.

[0028] Specifically, such as Figure 3 As shown, the top of the filament bracket 1 is threaded with a lead screw 302, which is rotatably connected to the fixing member 303.

[0029] The side wall of the filament bracket 1 has multiple sets of connecting grooves 3012. The connector 301 is inserted into the connecting groove 3012. The top of the connector 301 has a fixing hole 3011. The fixing member 303 is inserted into the fixing hole 3011. By inserting the connector 301 on the tension spring 2 into the connecting groove 3012 of the filament bracket 1, and rotating the screw 302 downward, the fixing member 303 can be moved downward until the fixing member 303 is inserted into the fixing hole 3011 on the connector 301, thus fixing the tension spring 2.

[0030] Specifically, such as Figure 4 As shown, an adjustment assembly 4 is provided between the filament support 1 and the filament contact post 101. The adjustment assembly 4 is used to move the filament contact post 101. The adjustment assembly 4 includes a movable plate 402, which is located at the bottom of the filament contact post 101. A screw 403 is rotatably connected to the bottom of the filament support 1. The movable plate 402 is threadedly connected to the outer periphery of the screw 403. By providing the adjustment assembly 4 between the filament support 1 and the filament contact post 101, the height of the filament contact post 101 can be adjusted by rotating the screw 403. This facilitates adjustment according to different filament tensions and improves its applicability.

[0031] A stabilizing rod 401 is fixedly connected to the bottom of the filament contact post 101. The stabilizing rod 401 passes through the bottom of the filament bracket 1. The movable plate 402 is fixedly connected to the bottom of the stabilizing rod 401. By rotating the screw 403, the movable plate 402 and the filament contact post 101 can be moved upward. At the same time, the stabilizing rod 401 improves the stability of the filament contact post 101 when it moves.

[0032] Specifically, such as Figure 5 As shown, a gear 404 is fixedly connected to the top of the screw 403. The gear 404 is rotatably connected inside the filament bracket 1. A limiting member 405 is slidably connected inside the filament bracket 1. The limiting member 405 and the gear 404 mesh with each other. By stretching the round rod 4051 and the limiting member 405 outward to move them away from the gear 404, the screw 403 can be rotated.

[0033] A round rod 4051 is fixedly connected to the end of the limiting member 405. The round rod 4051 passes through the side wall of the filament bracket 1. A return spring 406 is sleeved on the outer peripheral wall of the round rod 4051. The return spring 406 is fixedly connected between the filament bracket 1 and the limiting member 405. After the round rod 4051 is released, the elastic force of the return spring 406 can reset the round rod 4051 and the limiting member 405. At this time, the limiting member 405 will be inserted into the side wall of the gear 404 to limit the screw 403 and prevent the screw 403 from rotating randomly.

[0034] The specific steps of this solution are as follows: First, insert the connector 301 on the tension spring 2 into the connecting groove 3012 of the filament bracket 1. Then, rotate the screw 302 downwards to move the fixing member 303 downwards until the fixing member 303 is inserted into the fixing hole 3011 on the connector 301 to fix the tension spring 2. Next, connect the filament sequentially between the cylinder of the filament bracket 1 and the tension spring 2. At this time, the filament will overlap and contact the contact groove 1011 on the filament contact post 101. Finally, according to the tension of the filament, rotate the screw 403 to move the movable plate 402 and the filament contact post 101 upwards to increase the tension.

[0035] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.
