Description

Technical Field

[0001] This utility model relates to the technical field of steering gear casting shell structure, and in particular to a quick-release steering gear casting shell structure. Background Technology

[0002] As an essential component for automobile steering, the housing of the steering gear is usually manufactured by die casting for safety reasons.

[0003] However, for workpieces with complex overall structures such as steering gear housings, the initial casting and die-casting processes are costly and have long lead times. The subsequent CNC machining process often requires four-axis / five-axis CNC machining, which requires a large travel range and many processing limitations, thus restricting the production efficiency of one-piece steering gear housings. To address this, we propose a quick-release steering gear housing structure. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a quick-release steering gear casting shell structure.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a quick-release steering gear casting shell structure, including a first casting shell and a second casting shell. The first casting shell is detachably connected to the second casting shell. A sealing groove is provided at one end of the first casting shell corresponding to the second casting shell. A sealing structure is provided inside the sealing groove. First slots are provided at equal intervals on the outer side of the first casting shell. A first block is engaged inside the first slot. A protrusion is fixedly installed on the side of the first block. A first movable ring is movably installed on the outer side of several first blocks. A connecting internal threaded ring is fixedly installed at one end of the first movable ring. Second slots are provided at equal intervals on the outer side of the second casting shell. A second block is engaged inside the second slot. The second block is an "L"-shaped block. A second movable ring is movably installed on the outer side of the second block. An external threaded cylinder is fixedly installed at one end of the second movable ring corresponding to the connecting internal threaded ring. The external threaded cylinder is threadedly connected to the inside of the internal threaded ring.

[0006] Preferably, the sealing structure includes a sealing ring snapped into the sealing groove, the sealing groove being an annular groove, the sealing ring being an annular ring, and a compression ring fixedly installed on the second cast shell at the position corresponding to the sealing groove.

[0007] Preferably, the connecting internal threaded ring has an "L"-shaped circular cross-section, and a first groove is provided on the side of the connecting internal threaded ring corresponding to the position of the protrusion, with the protrusion engaging inside the first groove.

[0008] Preferably, two mounting cavities are symmetrically opened on the outer side of the second movable ring, and a swing block is rotatably installed inside the mounting cavity. The swing block is provided with a second groove, which is a rectangular groove.

[0009] Preferably, movable cavities are provided on both sides of the mounting cavity.

[0011] Beneficial effects

[0012] This utility model provides a quick-release steering gear housing structure. It has the following advantages:

[0013] (1) The quick-release steering gear housing structure, when the first and second housings are close to each other, achieves a seal between the first and second housings through a sealing structure, so that the external threaded cylinder rotates relative to each other, and the internal threaded ring and the external threaded cylinder move closer to each other. The internal threaded ring drives the first housing, and the external threaded cylinder drives the second housing, so that the first and second housings move relative to each other and connect the first and second housings together. This makes the complex steering gear housing form a two-section structure that can be disassembled and assembled into a relatively simple structure, which is conducive to simplifying the manufacturing process of each part of the steering gear housing, reducing the manufacturing difficulty of the steering gear housing, and improving production efficiency.

[0014] (2) The quick-release steering gear casting shell structure can reinforce the outer side of the first casting shell through the first locking block and the first moving ring, and can reinforce the outer side of the second casting shell through the second locking block and the second moving ring, so that it plays the role of a reinforcing rib and improves the strength.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-4As shown, a quick-release steering gear housing structure includes a first housing 1 and a second housing 2. The first housing 1 is detachably connected to the second housing 2. A sealing groove 3 is provided at one end of the first housing 1 corresponding to the second housing 2. A sealing structure is provided inside the sealing groove 3. First slots 6 are provided at equal intervals on the outer side of the first housing 1. First blocks 7 are engaged inside the first slots 6. Protrusions 8 are fixedly installed on the side of the first blocks 7. First moving rings 9 are movably installed on the outer side of several first blocks 7. The side of the first block 7 opposite to the inner side of the first moving ring 9 is arc-shaped and closely attached to the inner side of the first moving ring 9. On one side, a connecting internal threaded ring 10 is fixedly installed at one end of the first movable ring 9. A second slot 12 is equidistantly provided on the outer side of the second cast shell 2. A second locking block 13 is engaged inside the second slot 12. The second locking block 13 is an "L"-shaped block. A second movable ring 14 is movably installed on the outer side of the second locking block 13. An external threaded cylinder 15 is fixedly installed at one end of the second movable ring 14 corresponding to the connecting internal threaded ring 10. The external threaded cylinder 15 is threadedly connected to the inside of the connecting internal threaded ring 10. During use, when the first cast shell 1 and the second cast shell 2 are close together, a sealing structure is used to prevent the first cast shell 1 and the second cast shell 2 from coming into contact. The seal between the two cast shells 2 allows for relative rotation between the external threaded cylinder 15 and the connecting internal threaded ring 10 and the external threaded cylinder 15, causing them to move closer together. The connecting internal threaded ring 10 drives the first cast shell 1, which in turn drives the second cast shell 2 via the external threaded cylinder 15, resulting in mutual movement between the first and second cast shells 1 and 2. This connects the first and second cast shells 1 and 2 together, transforming the complex steering gear housing into a detachable, relatively simple two-section structure. This simplifies the manufacturing process of each part of the steering gear housing, reduces manufacturing difficulty, and improves production efficiency. The first locking block 7 and the first moving ring 9 can reinforce the outer side of the first cast shell 1, and the second locking block 13 and the second moving ring 14 can reinforce the outer side of the second cast shell 2, so that it acts as a reinforcing rib and improves the strength. The sealing structure includes a sealing ring 4 that is snapped into the sealing groove 3. The sealing groove 3 is a circular groove and the sealing ring 4 is a circular ring. The second cast shell 2 is fixedly installed with a compression ring 5 at the position corresponding to the sealing groove 3. When the first cast shell 1 and the second cast shell 2 approach each other, they compress the sealing ring 4, so that the sealing ring 4 fills the interior of the sealing groove 3 and achieves a sealing effect.

[0024] The connecting internal threaded ring 10 is an L-shaped circular ring. A first groove 11 is provided on the side of the connecting internal threaded ring 10 corresponding to the position of the protrusion 8. The protrusion 8 is engaged inside the first groove 11. By engaging the protrusion 8 inside the first groove 11, the movement of the connecting internal threaded ring 10 is constrained. The external threaded cylinder 15 is rotated by the second moving ring 14. The external threaded cylinder 15 rotates inside the connecting internal threaded ring 10, which facilitates the tightening of the second moving ring 14. Two mounting cavities 16 are symmetrically provided on the outer side of the second moving ring 14. A swing block 17 is rotatably installed inside the mounting cavity 16. The swing block 17 is provided with a second groove 18. The second groove 18 is a rectangular groove. The swing block 17 can rotate out from inside the mounting cavity 16 to form a force application point, which makes it easier to rotate the second moving ring 14.

[0025] Movable cavities 19 are provided on both sides of the mounting cavity 16. A rotating shaft 20 is fixedly installed on the side of the second groove 18 corresponding to the position of the movable cavity 19. The rotating shaft 20 is rotatably installed inside the movable cavity 19. A torsion spring 21 is fixedly installed at the end of the rotating shaft 20 away from the second groove 18. The end of the torsion spring 21 away from the rotating shaft 20 is fixedly installed on the end face of the movable cavity 19. The rotation of the second groove 18 is reset by the rotating shaft 20 and the torsion spring 21.

[0026] The working principle of this utility model:

[0027] In use, when the first cast shell 1 and the second cast shell 2 approach each other, a sealing structure achieves a seal between them, allowing the external threaded cylinder 15 to rotate relative to each other. The connecting internal threaded ring 10 and the external threaded cylinder 15 move closer together. The internal threaded ring 10 drives the first cast shell 1, which in turn drives the second cast shell 2 via the external threaded cylinder 15, causing them to move relative to each other and connecting them together. This transforms the complex steering gear housing into a detachable, relatively simple two-section structure, simplifying the manufacturing process of each part of the steering gear housing, reducing manufacturing difficulty, and improving production efficiency. The first locking block 7 and the first moving ring 9 can reinforce the outer side of the first cast shell 1. The second locking block 13 and the second moving ring 14 can reinforce the outer side of the second cast shell 2, making it act as a reinforcing rib and improving its strength. When the first cast shell 1 and the second cast shell 2 approach each other, they compress the sealing ring 4, causing the sealing ring 4 to fill the interior of the sealing groove 3, thus achieving a sealing effect. The movement of the connecting internal thread ring 10 is constrained by engaging the protrusion 8 inside the first groove 11. The external thread cylinder 15 is rotated by the second moving ring 14, and the external thread cylinder 15 rotates inside the connecting internal thread ring 10, making it easier to tighten the second moving ring 14. The swing block 17 can rotate out from inside the mounting cavity 16 to form a force application point, making it easier to rotate the second moving ring 14. The rotation of the second groove 18 is reset by the rotating shaft 20 and the torsion spring 21.
