Description

Technical Field

[0001] This utility model relates to the field of brake hose manufacturing technology, and in particular to a brake braided hose tension sensing device and braiding machine. Background Technology

[0002] The application of steel braided brake hoses is an inevitable product of the pursuit of "precise control" and "absolute reliability" in automotive braking technology development. Through advancements in materials science (Teflon liner + stainless steel braiding), it fundamentally solves the core problems of traditional rubber hoses, such as expansion under high pressure and poor durability. While original rubber hoses are sufficiently safe for ordinary commuter vehicles within their normal service life, upgrading to steel hoses is a key technology that significantly improves vehicle active safety and driving confidence for any scenario with higher braking performance requirements. In manufacturing high-quality steel brake hoses, ensuring consistent tension in each (or bundle of) steel wire during the braiding process is one of the most critical indicators of its manufacturing process and product quality. Uneven tension leads to inconsistent braid density, affecting overall compressive strength and fatigue life; in extreme cases, localized stress concentration may occur, causing premature wire breakage. Utility Model Content

This is one of the most critical core indicators for measuring the level of craftsmanship and product quality. Uneven tension will lead to inconsistent density of the braided layer structure, affecting the overall compressive strength and fatigue life.

[0023] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0024] Please combine them together Figures 1 to 2 The present invention will now describe the brake braiding throat tension sensing device. The brake braiding throat tension sensing device is used in a braiding machine.

[0025] The brake braided throat tension sensing device includes: a frame 1, a mounting base 2, a drive assembly 3, a winder 4, and a pull-out force sensor 5. The drive assembly 3 is fixed to the mounting base 2 and is connected to the winder 4. The mounting base 2 is slidably connected to the frame 1. One end of the pull-out force sensor 5 is fixed to the frame 1, and the other end is mounted on the mounting base 2. The drive assembly 3 drives the winder 4 to rotate. The winder 4 winds up the wire released by the unwinding device and can generate tension. The mounting base 2, the drive assembly 3, and the winder 4 slide relative to the frame 1. The pull-out force sensor 5 senses the tension to obtain the tension of the wire.

[0026] Understandably, the drive assembly 3 of the brake braided throat tension sensing device is fixed to the mounting base 2 and is connected to the winding device 4. The mounting base 2 is slidably connected to the frame 1. One end of the pull-out force sensor 5 is fixed to the frame 1, and the other end is installed on the mounting base 2. The drive assembly 3 drives the winding device 4 to rotate. The winding device 4 winds up the wire released by the wire release device and can generate tension, so that the mounting base 2, drive assembly 3 and winding device 4 slide relative to the frame 1. The pull-out force sensor 5 senses the tension to obtain the tension of the wire, thereby avoiding uneven wire tension that leads to inconsistent braiding layer structure, improving overall compressive strength and fatigue life, avoiding local stress concentration, and preventing premature wire breakage.

[0027] It should be noted that the drive assembly 3 drives the take-up reel 4 to rotate. The take-up reel 4 can wind the steel wire released from the pay-off wheel of the pay-off device. During this process, the steel wire exerts a certain tension on the take-up reel 4, causing the take-up reel 4, drive assembly 3, and mounting base 2 to move relative to the frame 1 towards the pay-off device. At this time, the tension sensor 5 is subjected to the tension of the mounting base 2, thereby sensing this tension and converting it into tension. When the tension of a certain bundle of steel wire deviates from the preset range (±3%), the pay-off device can adjust the torque of the corresponding pay-off wheel to achieve automatic tension correction. Multiple or multiple bundles of steel wire are limited to one yarn bobbin. Therefore, during rotation, only the tension of one yarn bobbin is adjusted. After the tension adjustment is completed, the device switches to the next yarn bobbin, repeating this action until the tension of all yarn bobbins is completed.

[0028] In this embodiment, the pull force sensor 5 includes a body 51 and a connector 52 connected to the body 51. The brake braided hose tension sensing device also includes a pulling member 6, which is fixed to the mounting base 2 and used to connect to the connector 52. Thus, when the mounting base 2 moves, the mounting base 2 drives the pulling member 6 to move, and the pulling member 6 generates a pulling force on the connector 52, which is then sensed by the body 51.

[0029] Specifically, the connector 52 includes a connecting rod 521 and an abutment 522 connected to the connecting rod 521. The pull member 6 has a groove 61, the connecting rod 521 is disposed in the groove 61, and the abutment 522 abuts against one side of the pull member 6. The mounting base 2 drives the pull member 6 to move. When the pull member 6 abuts against the abutment 522, the pull member 6 generates a pulling force on the abutment 522, and the abutment 522 generates a pulling force on the connecting rod 521. The body 51 then senses this pulling force.

[0030] In one embodiment, such as Figure 1 As shown, the brake braided hose tension sensing device also includes a sliding structure 7, which is used for sliding the mounting base 2 relative to the frame 1. This allows the mounting base 2 to move relative to the frame 1 in a preset direction.

[0031] In this embodiment, the sliding structure 7 includes a slide rail 71 and a slider 72. The slide rail 71 is fixed to the frame 1, and the slider 72 is fixed to the mounting base 2. The slider 72 is slidably connected to the slide rail 71. This allows the mounting base 2 to slide relative to the frame 1.

[0032] In one embodiment, continue as follows Figure 1 As shown, the drive assembly 3 includes a drive motor 31 and a connecting shaft 32. The drive motor 31 is connected to the winder 4 via the connecting shaft 32. The drive motor 31 drives the connecting shaft 32 to rotate, and the connecting shaft 32 drives the winder 4 to rotate, thereby winding the steel wire.

[0033] In this embodiment, the brake braided throat tension sensing device further includes a guide 8, which is fixed to the frame 1 and used to guide the steel wire to be wound onto the winder 4. This allows the steel wire to be smoothly wound onto the winder 4.

[0034] Specifically, the guide 8 is provided with a guide hole 81 through which the steel wire passes.

[0035] In one embodiment, continue as follows Figure 1 As shown, the brake braided throat tension sensing device also includes a controller 9, which controls the switching and operating speed of the drive assembly 3. This allows control over the switching of the device and the winding speed of the take-up coil 4.

[0036] This utility model also provides a braiding machine, which includes a wire feeding device and a brake braiding throat tension sensing device according to any of the above embodiments. The brake braiding throat tension sensing device is used to sense the wire tension of the wire feeding device.

[0037] It is understood that the braiding machine of this utility model uses the aforementioned brake braiding throat tension sensing device, so that the drive component 3 of the brake braiding throat tension sensing device is fixed to the mounting base 2 and is connected to the winding device 4 for transmission. The mounting base 2 is slidably connected to the frame 1. One end of the pull force sensor 5 is fixed to the frame 1 and the other end is installed on the mounting base 2. The drive component 3 drives the winding device 4 to rotate. The winding device 4 winds up the steel wire released by the unwinding device and can generate tension, so that the mounting base 2, drive component 3 and winding device 4 slide relative to the frame 1. The pull force sensor 5 senses the tension to obtain the tension of the steel wire, thereby avoiding uneven steel wire tension that leads to uneven braiding layer structure, improving overall compressive strength and fatigue life, avoiding local stress concentration, and avoiding premature breakage of the steel wire.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
