Description

Technical Field

[0001] The invention relates to the technical field of workpiece assembly, in particular to an anti-vibration type automobile brake rectangular ring auxiliary installation device. Background Art

[0002] The rectangular ring is also called the rectangular sealing ring. It is used for brake pumps. The function of the rectangular ring is to automatically adjust the piston brake clearance. The rectangular sealing ring is generally installed between the piston groove and the sealed surface. It has a certain amount of compression. The elastic force generated by this gives the sealed smooth surface and the bottom of the groove an initial compression stress. When the air ring with a rectangular cross-section moves back and forth with the piston, it will continuously send the engine oil on the cylinder wall into the cylinder.

[0003] During the assembly and disassembly process of the rectangular sealing ring, since its installation position is between the brake caliper and the piston, it is not easy to quickly locate it to the installation area inside the caliper during the initial assembly process. During the braking process, the piston of the brake caliper will extend. If the rectangular sealing ring is improperly assembled or the rectangular sealing ring is aged, due to the existence of friction, the rectangular ring mounted on the piston will produce axial movement with the movement of the piston, thereby causing oil leakage.

[0004] Furthermore, when the rectangular ring is disassembled and replaced, it is easy to deform due to long-term compression or oil leakage, resulting in the rectangular ring and the caliper body being stuck, making it difficult to remove. Summary of the invention

[0016] (III) Beneficial effects: Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: 1. By providing a clamping mechanism, when the user needs to install a rectangular sealing ring, the rectangular sealing ring is pre-received and fixed in the piston body by controlling the clamping plate, and the clamping plate is released after the piston body is installed in the brake caliper body, so that the rectangular sealing ring enters the slot through its own elastic force, and docks with the slide groove inside the slot through its surface ring block, so that the device can synchronize the installation action of the piston body with the installation action of the rectangular ring. The integrated implementation not only reduces the difficulty, but also is more conducive to the positioning of the rectangular sealing ring in the narrow space of the piston body. When there is a need to replace the rectangular sealing ring, the clamping plate can be controlled to clamp the installed rectangular sealing ring by controlling the movement process and rotation amplitude of the clamping plate, so that the device can conveniently complete the disassembly action of the rectangular sealing ring, further reducing the risk of jamming.

[0017] 2. By providing a leveling mechanism, when the clamping plate releases the clamping action on the fixed rectangular sealing ring, the wave plate can be continuously triggered by the clamping plate, so that the push plate provides auxiliary driving force for the rectangular sealing ring that pops into the slot, and under the continuous resistance of the clamping plate to the wave plate, the airbag is intermittently inflated, and then the rectangular sealing ring is subjected to wave resistance, so that the rectangular sealing ring is fully fitted into the slot, so as to ensure that the rectangular sealing ring is fully assembled to the specified position, and when the rectangular sealing ring needs to be removed, the same operation can be performed to make the airbag again resist the rectangular sealing ring, thereby eliminating the oil adhesion between the surface of the rectangular sealing ring and the inner wall of the slot, thereby helping the subsequent rectangular sealing ring to be smoothly removed from the slot.

[0018] 3. When the rectangular sealing ring is in the installed state, after running for several cycles, the user can trigger the inflation operation of the airbag again. If the rotating rod can rotate smoothly, it means that the airbag can be inflated smoothly, which means that there is no misalignment in the installation posture of the rectangular sealing ring. Otherwise, it means that there is misalignment, which enables the device to perform effective self-inspection, further avoid errors in manual identification, and help personnel effectively judge and know the operating status of the piston body and the rectangular sealing ring.

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] The present invention will be further described below in conjunction with the embodiments.

[0039] Embodiment 1: This embodiment is a vibration-proof automobile brake rectangular ring auxiliary installation device, such as Figure 1-Figure 10 As shown, it includes a brake caliper body 1, the interior of the brake caliper body 1 is slidably connected to a piston body 2, a groove 7 is provided on the inner wall of the brake caliper body 1, a rectangular sealing ring 4 is provided inside the groove 7, the surface of the rectangular sealing ring 4 is provided with an annular protrusion, and an annular convex groove corresponding to the annular protrusion on the surface of the rectangular sealing ring 4 is provided on the inner wall of the groove 7, and a clamping mechanism, a leveling mechanism and an adjusting mechanism are provided inside the piston body 2, wherein: the clamping mechanism includes a connecting plate 32 and a clamping plate 36, and the clamping mechanism is used to synchronously complete the clamping, clamping and releasing installation of the rectangular sealing ring 4 by adjusting the displacement distance of the connecting plate 32 and the rotation amplitude of the clamping plate 36.

[0040] There are three connecting plates 32, which are equidistantly and slidably connected to the inside of the piston body 2. A toothed plate 34 is slidably connected to the surface of the connecting plate 32. Gears 33 are meshed at both the upper and lower ends of the toothed plate 34. The central axis of the gear 33 is rotatably connected to the surface of the connecting plate 32. One end of the clamping plate 36 is fixedly connected to the surface of the toothed plate 34. Three sleeves 31 are provided on the surface of the piston body 2.

[0041] The interior of the toothed plate 34 is rotatably connected to a rotating rod 35 via a thread. The end of the rotating rod 35 away from the toothed plate 34 passes through the piston body 2 and is rotatably connected to the piston body 2. The piston body 2 limits the moving trajectory of the rotating rod 35 so that the adjustment operation can be completed conveniently.

[0042] Compared with the prior art, by pre-fixing the rectangular sealing ring 4, the installation behavior of the piston body 2 is converted into the installation behavior of the rectangular sealing ring 4, so that the rectangular sealing ring 4 can quickly find the installation position during the installation process, and in this process, the function of the clamping related components can be switched, so that it is converted from the installation function to the disassembly function of the installed rectangular sealing ring 4, thereby enriching the functionality while greatly reducing the difficulty of disassembling the aged or deformed rectangular sealing ring 4.

[0043] Embodiment 2: In other aspects, this embodiment also provides a leveling mechanism, such as Figure 3 As shown, the leveling mechanism includes a wave plate 51, the number of the wave plates 51 is the same as the clamping plate 36, a single wave plate 51 is correspondingly arranged on one side of the single clamping plate 36, one end of the wave plate 51 is slidingly connected to the inner wall of the piston body 2, one end of the wave plate 51 is fixedly connected to a movable rod 52, the movable rod 52 is slidingly connected to the inner wall of the piston body 2, a spring 53 is sleeved on the surface of the movable rod 52, one end of the spring 53 is fixedly connected to one end of the movable rod 52, and the other end of the spring 53 is fixedly connected to the inner wall of the piston body 2.

[0044] A push plate 55 is provided at one end of the movable rod 52 away from the wave plate 51, and a hollow rod 57 is fixedly connected to one end of the push plate 55. Two air bags 59 are installed inside the push plate 55, and the air bags 59 are connected to the hollow rod 57. A connecting block 56 is rotatably connected to the surface of the hollow rod 57, and one end of the connecting block 56 is fixedly connected to the inner wall of the piston body 2. A spring 2 58 is sleeved on the surface of the hollow rod 57, and one end of the spring 2 58 is fixedly connected to the surface of the hollow rod 57, and the other end of the spring 2 58 is fixedly connected to the inner wall of the connecting block 56. A ventilation groove 54 is provided on the inner wall of the piston body 2 near the movable rod 52, and the ventilation groove 54 is connected to the connecting block 56 and the hollow rod 57.

[0045] Compared with the prior art, by switching the rotation direction of the clamp plate 36, it can correspondingly complete the fitting process of the newly installed rectangular sealing ring 4 and the loosening process of the rectangular sealing ring 4 to be removed, so that it can realize important functions in different cycles. Compared with the traditional manual prying and removal method using a screwdriver, it is more convenient and not easy to damage the inner wall of the brake caliper body 1.

[0046] Embodiment 3: In this embodiment, as Fig.10 As shown, an adjustment mechanism is also provided, which includes a movable groove 61, which is provided on the inner wall at the top of the piston body 2, and a sliding block 62 is slidably connected inside the movable groove 61, and a driving block 63 is rotatably connected to the bottom end of the sliding block 62, and three connecting rods 64 are equidistantly arranged at the top of the driving block 63, and the bottom ends of the three connecting rods 64 are all fixedly connected to the top of the connecting plate 32, and a spiral pattern is provided on the surface of the lower side of the inner wall of the movable groove 61, and the driving block 63 is rotatably connected to the movable groove 61 through the spiral pattern and limits the moving trajectory, and the ends of the three connecting rods 64 that are close to each other are slidably connected to the sliding block 62, and the ends of the three connecting rods 64 that are away from each other are slidably connected to the inner wall of the piston body 2.

[0047] Working principle: In the actual application process of the present invention, when the rectangular sealing ring 4 is initially installed, the piston body 2 remains separated from the brake caliper body 1, the rectangular sealing ring 4 is separated from the slot 7, and the three sleeves 31 are separated from the piston body 2.

[0048] like Figure 3 and Fig. 9 As shown, the user first inserts the rectangular sealing ring 4 into the piston body 2 so that three places on its surface are between the two clamping plates 36. During the insertion process of the rectangular sealing ring 4, the rectangular sealing ring 4 resists the push plate 55, and the push plate 55 is forced to drive the hollow rod 57 to rotate in the connecting block 56, and during the rotation process, the hollow rod 57 of the push plate 55 drives the spring 2 58 to stretch. As the push plate 55 continues to rotate, it will eventually resist the wave plate 51 and the inclined surface of the wave plate 51, so that the wave plate 51 is forced to drive the movable rod 52 to move and drive the spring 1 53 to stretch. When the push plate 55 moves to the limit distance, the spring 1 53 rebounds by its own resilience, thereby driving the wave plate 51 to reset, and the wave plate 51 temporarily limits and fixes the push plate 55.

[0049] The user can then rotate the rotating rod 35 by means of a tool such as a right-angle wrench, so that the rotating rod 35 drives the toothed plate 34 to move on its surface under the action of the thread and the limitation of the movement trajectory of the toothed plate 34 by the connecting plate 32. During the movement, the toothed plate 34 drives the gear 33 to rotate, and the two clamping plates 36 are correspondingly driven by the gear 33 to move closer to each other. During the process of the two clamping plates 36 approaching each other, the surface of the rectangular sealing ring 4 is fixed. During this process, the rectangular sealing ring 4 is in a state of being retracted into the piston body 2. The user can now install the piston body 2 into the brake caliper body 1. After the installation is completed, the rotating rod 35 is rotated in the opposite direction so that the clamping plate 36 releases the clamping of the rectangular sealing ring 4. At this time, the rectangular sealing ring 4 is inserted into the slot 7 through the rebound characteristics of the rectangular sealing ring 4 itself. Due to the annular block on the surface of the rectangular sealing ring 4 and the annular groove corresponding to the slot 7, the rectangular sealing ring 4 is effectively prevented from being misaligned during the movement of the piston body 2.

[0050] like Figure 3 ,and Figure 8 As shown, after the rectangular sealing ring 4 is installed, the user can rotate the rotating rod 35 in the opposite direction to make the clamping plate 36 move in the opposite direction, and the convex block on the surface of the clamping plate 36 continuously contacts the wavy convex block on the surface of the wave plate 51. During this process, the wave plate 51 is continuously subjected to force to drive the movable rod 52 in a cyclic movement and reset state, and the movable rod 52 continuously drives the spring 53 to stretch and reset. During the continuous rebound of the movable rod 52, the movable rod 52 continuously injects air into the connecting block 56 through the vent groove 54, so that the air enters the airbag 59 through the hollow rod 57. The airbag 59 is in a cyclic inflation and deflation state, and then fits and contacts the edge of the newly installed rectangular sealing ring 4, so that it is fully assembled into the slot 7. After confirming that the installation is complete, the piston body 2 can be taken out of the brake caliper body 1, and the sleeve 31 can be installed on the surface of the piston body 2.

[0051] In addition, when the rectangular sealing ring 4 needs to be disassembled, the piston body 2 can be removed, the sleeve 31 can be taken off and then reinstalled, and then the operation can be triggered by the same clamping plate 36 to loosen the mutual bonding state between the rectangular sealing ring 4 and the slot 7 caused by oil leakage or material aging.

[0052] like Figure 7 and 10 As shown, the user then pushes the push plate 55 to re-fix it with the wave plate 51, and then rotates the drive block 63 with a tool such as a screwdriver. Under the action of the thread, the drive block 63 rises in the movable groove 61 and pushes the sliding block 62 to rise. During the rising process, the sliding block 62 pushes the connecting rod 64 to slide on its surface, thereby driving the connecting plate 32 to move laterally, so that the clamping plate 36 probes into the slot 7. Then the user can rotate the rotating rod 35 again to make the clamping plate 36 clamp the rectangular sealing ring 4, and then rotate the drive block 63 in the opposite direction to make the clamping plate 36 take the rectangular sealing ring 4 out of the slot 7 to complete the disassembly.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
