Abstract
Description
Technical Field
[0001] This utility model relates to the field of brake master cylinder ring assembly technology, specifically an integrated plunger-type brake master cylinder ring assembly fixture. Background Technology
[0002] The brakes of a car are a key device to ensure safe driving. Brakes are generally hydraulically driven. When the brake pedal is pressed, the master cylinder pumps brake fluid from the reservoir, which flows through the outlet pipe to the brake calipers. The pistons in the brake calipers push the brake pads to brake the wheels.
[0003] To prevent high-pressure brake fluid from leaking out from the gap between the piston and cylinder, resulting in a complete loss of braking force, multiple sealing rings with different orientations are fitted in various locations within the master cylinder to form a sealed cavity. However, the opening of the master cylinder has a small diameter and a large internal space, making it difficult to observe deeper parts of the master cylinder. This makes it impossible to accurately install the sealing rings in these deeper parts of the master cylinder, making the installation of the sealing rings in these deeper parts of the master cylinder more complicated and affecting the assembly efficiency of the brake master cylinder rubber ring. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an integrated plunger-type brake master cylinder seal assembly fixture, which solves the problem of the cumbersome installation of the seal ring located deep within the master cylinder.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An integrated plunger-type brake master cylinder rubber ring assembly fixture includes a guide post and a limiting block. A threaded rod that is threadedly connected to the limiting block is fixedly installed on the guide post, and a rubber ring sleeve is sleeved on the guide post.
[0007] The guide post is equipped with an assembly mechanism that facilitates the installation of the brake ring sleeve at the corresponding position inside the brake master cylinder.
[0008] Preferably, the assembly mechanism includes a pressure column slidably mounted on a guide column, and the pressure column has a beveled edge.
[0009] Preferably, the assembly mechanism further includes a guide tube that is slidably mounted on the pressure column and used in conjunction with the limiting block, and two sets of semi-circular rubber rings are slidably mounted on the guide tube.
[0010] Preferably, the assembly mechanism further includes a limiting ring that is slidably mounted on the guide tube and used in conjunction with a semi-circular rubber ring, and the limiting ring is threaded with a fastening bolt.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention, through the assembly mechanism, uses a movable guide post to send the limiting block into the brake master cylinder and make contact with its bottom. A guide tube is then inserted into the brake master cylinder, leaving space for the installation of the brake ring sleeve. The locking bolts limit its position, and the brake ring sleeve is tilted and placed onto the guide post. A pressure post is inserted into the guide post and moves the brake ring sleeve, allowing it to pass through the pre-drilled opening in the guide tube and fit inside the brake master cylinder. This completes the installation of the brake ring sleeve, avoiding the cumbersome installation of seals located deep within the master cylinder. Attached Figure Description

[0019] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0020] Reference Figures 1-4 This embodiment proposes an integrated plunger-type brake master cylinder rubber ring assembly fixture, including a guide post 1 and a limiting block 2. The limiting block 2 of different heights can be replaced according to the rubber ring sleeve 12 of different depths. The limiting block 2 is a cylinder. A threaded rod 11 that is threadedly connected to the limiting block 2 is fixedly installed on the guide post 1, which facilitates the replacement of the limiting block 2 and also facilitates the movement of the limiting block 2 by the guide post 1. The rubber ring sleeve 12 is sleeved on the guide post 1. The rubber ring sleeve 12 can be installed in either the front or back side according to different installation positions.
[0021] The guide post 1 is equipped with an assembly mechanism 3 that facilitates the installation of the rubber ring sleeve 12 at the corresponding position in the brake master cylinder, thereby improving the assembly efficiency of the brake master cylinder rubber ring.
[0022] Assembly mechanism 3 includes a pressure post 31 slidably mounted on guide post 1. The pressure post 31 has a bevel 32. Because the cylinder bore size of the brake master cylinder is smaller than the size of the brake ring sleeve 12, the brake ring sleeve 12 is tilted onto the guide post 1, and then the bevel 32 of the pressure post 31 moves the brake ring sleeve 12 to maintain its tilted state, facilitating the pressing of the brake ring sleeve 12 into the brake master cylinder. Assembly mechanism 3 also includes a guide tube 33 slidably mounted on the pressure post 31 and used in conjunction with the limiting block 2. The guide tube 33 has a sliding... The assembly mechanism 3 includes two sets of semi-circular rubber rings 34. It also includes a limiting ring 35 that slides on the guide tube 33 and engages with the semi-circular rubber rings 34. A fastening bolt 36 is threaded onto the limiting ring 35. Adjusting the fastening bolt 36 adjusts the tightness of the limiting ring 35 around the two sets of semi-circular rubber rings 34, facilitating the adjustment of the positions of the semi-circular rubber rings and the limiting ring 35. When installing the rubber ring sleeve 12, a limiting block 2 of the corresponding height is selected and threaded onto the guide post 1. The guide post 1 is moved to send the limiting block 2 into the brake master cylinder and make contact with its bottom. The guide tube 33 is inserted into the brake master cylinder and, after contact with the limiting block 2, the guide tube 33 is moved outward a short distance to leave space for the installation of the rubber ring sleeve 12. The positions of the semi-circular rubber ring 34 and the limiting ring 35 are adjusted so that they contact the surface of the brake master cylinder. Then, the fastening bolt 36 is used to limit them, preventing the guide tube 33 from continuing to move into the brake master cylinder and closing the reserved space. The rubber ring sleeve 12 is then distinguished as positive or negative. After tilting the face, it is placed on the guide post 1. The pressure post 31 is inserted into the guide post 1 and drives the rubber ring sleeve 12 to move so that it contacts the limiting block 2. The pressure post 31 is rotated so that the tilted rubber ring sleeve 12 becomes vertical and is placed inside the brake master cylinder through the pre-reserved opening of the guide tube 33. The guide tube 33, pressure post 31, guide post 1 and limiting block 2 are moved out of the brake master cylinder in sequence, thereby completing the installation of the rubber ring sleeve 12, avoiding the more complicated installation of the sealing ring deep in the master cylinder.
[0023] Working principle: After selecting the appropriate height limit block 2, thread it onto the guide post 1. Move the guide post 1 to send the limit block 2 into the brake master cylinder and make contact with its bottom. Insert the guide tube 33 into the brake master cylinder and, after contact with the limit block 2, move the guide tube 33 outward a short distance to leave space for the installation of the rubber ring sleeve 12. Adjust the positions of the semi-circular rubber ring 34 and the limit ring 35 to make them contact the surface of the brake master cylinder. Then, limit the guide tube 33 by tightening the fastening bolt 36 to prevent it from moving further inward. The space reserved in the master cylinder is closed. After distinguishing the front and back sides of the rubber ring sleeve 12, it is tilted and placed on the guide post 1. The pressure post 31 is inserted into the guide post 1 and moves the rubber ring sleeve 12 to contact the limiting block 2. The pressure post 31 is rotated so that the tilted rubber ring sleeve 12 becomes vertical and is placed inside the master cylinder through the reserved opening of the guide tube 33. The guide tube 33, pressure post 31, guide post 1 and limiting block 2 are moved out of the master cylinder in sequence to complete the installation of the rubber ring sleeve 12.
