Abstract
Description
Technical Field
[0001] This application relates to the field of brake fluid reservoir airtightness testing, and more particularly to an airtight tooling fixture for a brake fluid reservoir. Background Technology
[0002] Brake fluid reservoirs are used to hold brake fluid and are used in the braking system of vehicles. They are typically installed at the rear of the engine compartment. During the manufacturing process of brake fluid reservoirs, their airtightness must be tested.
[0003] like Figure 1 As shown, the brake fluid reservoir 5 has an inlet head 51 at its upper end and an outlet head 52 on one side. When conducting an airtightness test on the brake fluid reservoir, the operator first tightens the reservoir cap onto the inlet head, then connects the air hose to the outlet head to inflate the reservoir. The airtightness of the reservoir is then determined by measuring the air pressure inside.
[0004] However, after the brake fluid reservoir airtightness test is completed, the staff still need to loosen and remove the reservoir cap, which is a rather cumbersome operation and results in low airtightness test efficiency, so it needs to be improved. Utility Model Content
[0005] To improve the efficiency of testing the airtightness of brake fluid reservoirs, this application provides an airtight tooling fixture for brake fluid reservoirs.
[0006] The airtight tooling fixture for a brake fluid reservoir provided in this application adopts the following technical solution:
[0007] An airtight fixture for a brake fluid reservoir includes a mounting frame, a placement seat, a first sealing assembly, and two second sealing assemblies; the placement seat is disposed on the mounting frame and is used to place the brake fluid reservoir.
[0008] The first sealing assembly includes a first driving member and a sealing block; the first driving member is disposed on the mounting bracket and is used to drive the sealing block to approach or move away from the upper end of the inlet head of the brake fluid reservoir, and the diameter of the sealing block is larger than the diameter of the inlet head;
[0009] Two second sealing assemblies are disposed opposite each other; each second sealing assembly includes a second drive member and a sealing seat; the second drive member is disposed on the mounting bracket and is used to drive the sealing seat closer to or away from the periphery of the inlet head.
[0010] By adopting the above technical solution, in practical applications, the operator positions the brake fluid reservoir in the placement seat, first activates the first drive component to make the sealing block press against the upper end of the inlet head, and then activates the second drive component to make the sealing seat abut against the periphery of the sealing block, thereby sealing the inlet head. The operator does not need to tighten the reservoir cap to the inlet head or loosen and remove the reservoir cap, which can quickly seal the inlet head. The operation is simple and convenient, thereby effectively improving the testing efficiency of the brake fluid reservoir's airtightness.
[0011] Preferably, the first sealing assembly further includes a connecting block, the connecting block being disposed on the power output shaft of the first driving member, the sealing block being disposed on the connecting block, and the diameter of the connecting block being the same as the diameter of the sealing block.
[0012] By adopting the above technical solution, a connecting block is set for the installation of the sealing block, and the diameter of the connecting block is the same as the diameter of the sealing block, so that the sealing seat can simultaneously abut against the sealing block and the connecting block, thereby improving the sealing performance between the sealing block and the liquid inlet head.
[0013] Preferably, the sealing block is detachably connected to the connecting block.
[0014] By adopting the above technical solution, and by setting the sealing block to be detachably connected to the connecting block, the severely worn sealing block can be replaced individually, thereby reducing maintenance costs.
[0015] Preferably, the sealing seat has a fitting groove at one end near the liquid inlet head to fit the periphery of the sealing block.
[0016] By adopting the above technical solution and setting the fitting groove, the sealing seat can be more tightly abutted against the sealing block, further improving the sealing performance between the sealing block and the fluid inlet head, thereby improving the accuracy of brake fluid reservoir air tightness testing.
[0017] Preferably, the sealing seat is provided with an abutment strip at the lower end of the fitting groove.
[0018] By adopting the above technical solution and setting an abutment strip that abuts against the periphery of the liquid inlet head, the sealing performance between the sealing block and the liquid inlet head can be further improved.
[0019] Preferably, the sealing seat has a clearance groove at the end away from the liquid inlet head, and the second driving member is partially located in the clearance groove.
[0020] By adopting the above technical solution, and by setting a relief groove, with the second driving component part located in the relief groove, the overall size of the second sealing assembly can be reduced, making the airtight tooling fixture structure more compact.
[0021] Preferably, the second sealing assembly further includes a slide rail and a slider, the slide rail being disposed on the mounting bracket, the slider being disposed on the lower side of the sealing seat, and the slider being slidably connected to the slide rail.
[0022] By adopting the above technical solution and setting slide rails and sliders, the stability of the second driving component driving the sealing seat to move is improved, so that the sealing seat can more stably and accurately abut and fit against the sealing block.
[0023] Preferably, the lower side of the sealing seat has an installation groove, and the slider is located in the installation groove.
[0024] By adopting the above technical solution, and by setting an installation groove with the slider located in the installation groove, the overall height of the second sealing component can be reduced, making the airtight tooling fixture structure more compact.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. The operator positions the brake fluid reservoir in the mounting base, first activates the first drive mechanism to press the sealing block against the upper end of the inlet head, then activates the second drive mechanism to press the sealing seat against the periphery of the sealing block, thus sealing the inlet head. The operator does not need to tighten or loosen the reservoir cap to the inlet head, which allows for quick sealing of the inlet head. The operation is simple and convenient, thereby effectively improving the efficiency of brake fluid reservoir airtightness testing.
[0027] 2. By setting a connecting block for the installation of the sealing block, and the diameter of the connecting block being the same as the diameter of the sealing block, the sealing seat can simultaneously abut against both the sealing block and the connecting block, thereby improving the sealing performance between the sealing block and the liquid inlet head;

By setting the fitting groove, the sealing seat can fit more tightly against the sealing block, further improving the sealing performance between the sealing block and the inlet head, thereby improving the accuracy of brake fluid reservoir air tightness testing.

[0035] The following is in conjunction with the appendix Figure 2-5 This application will be described in further detail.
[0036] This application discloses an airtight tooling fixture for a brake fluid reservoir.
[0037] Reference Figure 2 and Figure 3 The airtight tooling fixture includes a mounting frame 1, a placement seat 2, a first sealing component 3, and two second sealing components 4. The mounting frame 1 is placed horizontally on the table, and the placement seat 2 is fixedly connected to the mounting frame 1. The shape of the upper side of the placement seat 2 is adapted to the brake fluid reservoir 5 to achieve the positioning and placement of the brake fluid reservoir 5.
[0038] The first sealing assembly 3 includes a first driving member 31 and a sealing block 32. In this embodiment, the first driving member 31 is a cylinder. In other embodiments, the first driving member 31 can also be a hydraulic cylinder, an electric push cylinder, etc., and this application is not limited thereto. The first driving member 31 is fixedly connected to the mounting bracket 1 and located above the placement seat 2. The sealing block 32 is semi-circular and fixedly connected to the power output shaft of the first driving member 31. The first driving member 31 drives the sealing block 32 to move vertically, and the sealing block 32 is located directly above the fluid inlet head 51 of the brake fluid reservoir 5, so that the sealing block 32 moves closer to or further away from the fluid inlet head 51. At the same time, the diameter of the sealing block 32 is larger than the diameter of the fluid inlet head 51, so that when the sealing block 32 abuts against the upper end of the fluid inlet head 51, it seals the fluid inlet head 51.
[0039] Two second sealing components 4 are arranged opposite to each other. Specifically, the second sealing component 4 includes a second driving member 41 and a sealing seat 42. The second driving member 41 can be, but is not limited to, a cylinder, a hydraulic cylinder, an electric push cylinder, etc. The second driving member 41 is horizontally arranged and fixedly connected to the mounting bracket 1. The sealing seat 42 is fixedly connected to the power output shaft of the second driving member 41, and the sealing seat 42 is driven by the second driving member 41 to approach or move away from the periphery of the liquid inlet head 51.
[0040] In practical applications, the operator positions the brake fluid reservoir 5 in the placement seat 2, aligning the inlet head 51 with the sealing block 32. First, the first drive unit 31 is activated, causing the sealing block 32 to press firmly against the upper end of the inlet head 51. Then, the two second drive units 41 are activated, causing the two sealing seats 42 to simultaneously abut against the periphery of the sealing block 32, thus sealing the inlet head 51 and ensuring the airtightness of the brake fluid reservoir 5. Next, the air pipe is connected to the outlet head 52 to inflate the brake fluid reservoir 5. Finally, the air pressure inside the brake fluid reservoir 5 is measured to test its airtightness. During this process, the operator does not need to tighten or loosen the reservoir cap on the inlet head 51, allowing for quick sealing of the inlet head 51. The operation is simple and convenient, effectively improving the efficiency of testing the airtightness of the brake fluid reservoir 5.
[0041] In some embodiments, the first sealing assembly 3 further includes a connecting block 33, which is fixedly connected to the power output shaft of the first drive member 31. The sealing block 32 is fixedly connected to the connecting block 33. The shape of the connecting block 33 is the same as that of the sealing block 32, and the diameter of the connecting block 33 is the same as that of the sealing block 32. This allows the sealing seat 42 to simultaneously abut against both the sealing block 32 and the connecting block 33, thereby making the sealing seat 42 abut against the sealing block 32 more fully. This improves the sealing performance between the sealing block 32 and the inlet head 51, ensuring the accuracy of the airtightness test of the brake fluid reservoir 5.
[0042] In some embodiments, the sealing block 32 is detachably connected to the connecting block 33. In this embodiment, the sealing block 32 is fixedly connected to the connecting block 33 by bolts. In other embodiments, the sealing block 32 can also be detachably connected to the connecting block 33 by snap-fit, plug-in, or other means. This application does not limit this. Thus, the sealing block 32 can be detached from the connecting block 33 to facilitate maintenance of the sealing block 32 or to replace severely worn sealing blocks 32 individually, thereby reducing maintenance costs.
[0043] Reference Figure 4 and Figure 5 In some embodiments, the sealing seat 42 has a fitting groove 421 at one end near the liquid inlet head 51. The fitting groove 421 is semi-circular in shape to fit against the periphery of the sealing block 32 and the connecting block 33, so that the sealing seat 42 fits more tightly against the sealing block 32, further improving the sealing performance between the sealing block 32 and the liquid inlet head 51, thereby improving the accuracy of the airtightness test of the brake fluid reservoir 5.
[0044] In some embodiments, the sealing seat 42 protrudes from the lower end of the fitting groove 421 to form an abutment strip 422, which is also semi-circular in shape. The abutment strip 422 is used to abut against the periphery of the liquid inlet head 51, so that the sealing seat 42 is also tightly fitted to the liquid inlet head 51, which can further improve the sealing performance between the sealing block 32 and the liquid inlet head 51.
[0045] In some embodiments, a relief groove 423 is provided at the end of the sealing seat 42 away from the liquid inlet head 51, and the second driving member 41 is partially located in the relief groove 423, which can reduce the overall length of the second sealing assembly 4, that is, reduce the overall size of the second sealing assembly 4, making the airtight tooling fixture structure more compact.
[0046] In some embodiments, the second sealing assembly 4 further includes a slide rail 43 and a slider 44. The slide rail 43 is fixedly connected to the mounting bracket 1, and the slider 44 is fixedly connected to the lower side of the sealing seat 42. The slider 44 is slidably connected to the slide rail 43 to improve the stability of the second driving member 41 driving the sealing seat 42 to move, so that the sealing seat 42 can more stably and accurately abut against the sealing block 32. In this embodiment, there are two sliders 44, which makes the sliding of the sealing seat 42 more stable.
[0047] In some embodiments, a mounting groove 424 is provided on the lower side of the sealing seat 42, and the slider 44 is located in the mounting groove 424, which can reduce the overall height of the second sealing assembly 4 and further reduce the overall size of the second sealing assembly 4, making the airtight tooling fixture structure more compact.
[0048] The implementation principle of this embodiment is as follows: In practical application, the operator positions the brake fluid reservoir 5 in the placement seat 2, aligning the inlet head 51 with the sealing block 32. First, the first drive unit 31 is activated, causing the sealing block 32 to press against the upper end of the inlet head 51. Then, the two second drive units 41 are activated, causing the two sealing seats 42 to simultaneously abut against the periphery of the sealing block 32, thus sealing the inlet head 51 and ensuring the airtightness of the brake fluid reservoir 5. Next, the air pipe is connected to the outlet head 52 to inflate the brake fluid reservoir 5. Finally, the air pressure inside the brake fluid reservoir 5 is measured to test its airtightness. During this process, the operator does not need to tighten or loosen the reservoir cap on the inlet head 51, thus quickly sealing the inlet head 51. The operation is simple and convenient, effectively improving the efficiency of testing the airtightness of the brake fluid reservoir 5.
[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
