Description

Technical Field

[0001] This utility model relates to the field of oil seal processing technology, specifically to a fixing fixture for processing automotive brake oil seals. Background Technology

[0002] In automotive braking systems, brake fluid seals play a crucial role, effectively preventing brake fluid leakage and ensuring the normal operation of the braking system. With the continuous development of the automotive industry, the specifications of automotive brake fluid seals are becoming increasingly diverse to meet the needs of different vehicle models and braking system designs.

[0003] Traditional fixtures for machining automotive brake oil seals typically use clamping components of fixed dimensions. These clamping components are designed to be adapted to a specific specification of oil seal. When encountering automotive brake oil seals of different specifications, existing fixtures often cannot effectively clamp and fix them. Due to the limited clamping range of the fixtures, they cannot be flexibly adjusted according to the differences in the diameter, thickness, and other dimensions of the oil seal. This leads to the need to frequently change fixtures when machining oil seals of different specifications.

[0004] Therefore, a fixing fixture for machining automotive brake oil seals is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a fixing fixture for processing automotive brake oil seals in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A fixing fixture for machining automotive brake oil seals includes a ring body and an oil seal ring. A frame is fixedly installed on the inner wall of the ring body, and an inner diameter clamping assembly is provided inside the frame. A first rubber pressure roller is fixedly installed on the movable part of the inner diameter clamping assembly. An outer diameter clamping assembly is provided on the surface of the ring body, and a second rubber pressure roller is fixedly installed on the movable part of the outer diameter clamping assembly. The first rubber pressure roller and the second rubber pressure roller are adjusted by the inner diameter clamping assembly and the outer diameter clamping assembly, respectively, to fix the inner and outer diameters of the oil seal ring.

[0008] Furthermore, the inner diameter clamping assembly includes a knob that is rotatably inserted into the top of the frame, with a first bevel gear fixedly installed at the bottom end of the knob. A first threaded rod is rotatably inserted into both sides of the frame, and a second bevel gear is fixedly installed at the end of the first threaded rod. The second bevel gear meshes with the first bevel gear. A movable block is threadedly fitted onto the surface of the first threaded rod, and a first rubber pressure roller is fixed to the top of the movable block.

[0009] Furthermore, guide rods are fixedly installed on the inner walls of both sides of the frame, and the movable block is slidably sleeved on the surface of the guide rods inside the frame.

[0010] Furthermore, the outer diameter clamping assembly includes a conical toothed ring rotatably sleeved on the surface of the ring body, and a dial is fixedly sleeved on the surface of the conical toothed ring. An internally threaded sleeve rod is rotatably inserted into the ring body, and a third conical gear is fixedly sleeved on the surface of the internally threaded sleeve rod. The third conical gear meshes with the conical toothed ring. A second threaded rod is internally threaded into the internally threaded sleeve rod, and a movable frame is fixedly installed at the end of the second threaded rod. A second rubber pressure roller is fixed on the movable frame.

[0011] Furthermore, the cross-section of the ring body is L-shaped, and its conical toothed ring and dial are rotatably arranged on the stepped surface of the ring body, and the surface of the ring body is provided with mounting protrusions.

[0012] Furthermore, the movable frame is slidably inserted inside the frame to guide the lateral movement of the movable frame and the second rubber pressure roller.

[0013] The beneficial effects of this utility model are as follows:

[0014] The inner diameter clamping assembly's movable part radially supports and presses the inner wall of the oil seal ring from the inside via a first rubber pressure roller. The outer diameter clamping assembly's movable part, located on the ring surface, presses the outer wall of the oil seal ring from the outside via a second rubber pressure roller.

Therefore, they should not be construed as limitations on this utility model.

[0024] like Figures 1 to 4 As shown, a fixing fixture for processing automotive brake oil seals includes a ring body 1 and an oil seal ring 5. A frame body 2 is fixedly installed on the inner wall of the ring body 1, and an inner diameter clamping assembly 3 is provided inside the frame body 2. A first rubber pressure roller 31 is fixedly installed on the movable part of the inner diameter clamping assembly 3.

[0025] like Figure 2 and Figure 3 As shown, specifically, the inner diameter clamping assembly 3 includes a knob 301 that is rotatably inserted into the top of the frame 2. A first bevel gear 302 is fixedly installed at the bottom end of the knob 301. A first threaded rod 303 is rotatably inserted into the two side walls of the frame 2. A second bevel gear 304 is fixedly installed at the end of the first threaded rod 303. The second bevel gear 304 meshes with the first bevel gear 302. A movable block 305 is threadedly sleeved on the surface of the first threaded rod 303. A first rubber pressure roller 31 is fixed to the top of the movable block 305.

[0026] More specifically, rotating the knob 301 causes the first bevel gear 302 fixed at its bottom to rotate. The first bevel gear 302 meshes with the second bevel gear 304 at the end of the first threaded rod 303, causing the four first threaded rods 303 to rotate synchronously. The movable block 305, which is threadedly connected to the first threaded rod 303, moves linearly, thereby driving the first rubber pressure roller 31 at its top to move radially, thus clamping and loosening the inner diameter of the oil seal ring 5.

[0027] In some practical applications, guide rods are fixedly installed on the inner walls of both sides of the frame 2, and the movable block 305 is slidably sleeved on the surface of the guide rod inside the frame 2.

[0028] More specifically, the guide rod can limit and guide the lateral movement of the movable block 305, preventing it from rotating with the first threaded rod 303.

[0029] The surface of the ring 1 is provided with an outer diameter clamping assembly 4. A second rubber pressure roller 41 is fixedly installed on the movable part of the outer diameter clamping assembly 4. The first rubber pressure roller 31 and the second rubber pressure roller 41 are adjusted by the inner diameter clamping assembly 3 and the outer diameter clamping assembly 4 respectively to fix the inner and outer diameters of the oil seal ring 5.

[0030] like Figures 1 to 4 As shown, specifically, the outer diameter clamping assembly 4 includes a conical toothed ring 401 rotatably sleeved on the surface of the ring body 1, and a dial 402 is fixedly sleeved on the surface of the conical toothed ring 401. An internally threaded sleeve 403 is rotatably inserted into the ring body 1, and a third conical gear 404 is fixedly sleeved on the surface of the internally threaded sleeve 403. The third conical gear 404 and the conical toothed ring 401 mesh with each other. A second threaded rod 405 is internally threaded into the internally threaded sleeve 403. A movable frame 406 is fixedly installed at the end of the second threaded rod 405, and a second rubber pressure roller 41 is fixed on the movable frame 406.

[0031] More specifically, by actuating the dial 402 fixedly sleeved on the conical gear ring 401, the conical gear ring 401 can be driven to rotate. The internal threaded sleeve 403 is rotatably inserted into the ring body 1 through a bearing. The third conical gear 404 fixed on its surface meshes with the internal conical teeth of the conical gear ring 401. Therefore, the rotation of the conical gear ring 401 will drive the third conical gear 404 and the internal threaded sleeve 403 to rotate together. The second threaded rod 405 is threadedly inserted into the inside of the internal threaded sleeve 403. The rotation of the internal threaded sleeve 403 will drive the second threaded rod 405 to produce axial linear motion, thereby pushing the movable frame 406 fixed at its end and the second rubber pressure roller 41 to move radially, thereby achieving the clamping and loosening of the outer diameter of the oil seal ring 5.

[0032] like Figure 3 As shown, in some practical applications, the cross-section of the ring 1 is L-shaped, and its conical tooth ring 401 and dial 402 are rotatably arranged on the stepped surface of the ring 1, and mounting protrusions are provided on the surface of the ring 1.

[0033] More specifically, the conical tooth ring 401 and the dial 402 are mounted on the stepped surface of the ring body 1 via a plane bearing, allowing them to rotate smoothly.

[0034] like Figure 3 As shown, in some practical applications, the movable frame 406 is slidably inserted inside the frame 2 to guide the lateral movement of the movable frame 406 and the second rubber pressure roller 41.

[0035] More specifically, the movement of the movable frame 406 is guided by the inner wall of the frame 2.

[0036] In summary: The movable part of the inner diameter clamping assembly 3 supports and presses the inner wall of the oil seal ring 5 radially from the inside through the first rubber pressure roller 31 thereon. The movable part of the outer diameter clamping assembly 4 provided on the surface of the ring body 1 presses the outer wall of the oil seal ring 5 from the outside through the second rubber pressure roller 41 thereon. By adjusting the inner diameter clamping assembly 3 and the outer diameter clamping assembly 4 respectively, the first rubber pressure roller 31 and the second rubber pressure roller 41 can be driven to move in opposite directions or in opposite directions, so as to firmly clamp and fix the oil seal rings 5 ​​of different specifications from both the inside and outside sides at the same time, preventing them from moving or deforming during the processing of the oil seal ring 5.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
