Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive axle housing processing technology, and in particular to a driving axle housing pawl hole surface leveling mold. Background Technology
[0002] As a key component of the automotive chassis transmission system, the drive axle housing's structural strength and assembly precision directly affect the vehicle's transmission efficiency and safety. The bore, a crucial connecting surface of the drive axle housing, requires surface finishing through a leveling process after welding or casting to ensure tightness and geometric accuracy in subsequent assembly. Therefore, developing a dedicated mold for efficient and stable leveling of the bore surface of the drive axle housing is of great significance for improving product quality and manufacturing consistency.
[0003] Currently, leveling molds used for the pipa hole surface of drive axle housings typically consist of a base, a fixed seat, a positioning mechanism, and a clamping device. During use, the operator manually places the axle housing onto the mold, uses bolt-fastened limit blocks to achieve initial positioning, and then applies uniform pressure to the pipa hole surface using an upper pressure plate to achieve localized correction. This type of structure is simple in design, has low processing costs, and is widely used in small- to medium-batch production.
[0004] However, most existing mold limiting structures use a fixed installation method, which cannot be flexibly replaced and adjusted according to the different models of the drive axle housing, thus limiting the mold's adaptability. When the axle housing size changes or the process is adjusted, it is often necessary to replace the entire mold or perform repeated disassembly and debugging, which increases maintenance costs and seriously affects production efficiency and ease of operation. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a driving axle housing pipa hole surface leveling mold, which aims to improve the existing mold limiting structure, which is fixed and cannot be replaced according to different axle housing sizes, resulting in poor adaptability and low maintenance efficiency.

[0009] Furthermore, a side plate is fixedly connected to the outer wall of the base, and a hydraulic rod is fixedly connected to the upper surface of the side plate.
[0010] Furthermore, a connecting plate is fixedly connected to the output end of the hydraulic rod, and a limit rod is fixedly connected to the outer wall of the connecting plate.
[0011] Furthermore, a protective sleeve is fixedly connected to the outer wall of the connecting plate, and a motor is fixedly connected to the bottom of the inner wall of the protective sleeve.

[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, by setting a quick-release component inside the upright frame, the limit block and the electric slide rail can be quickly disassembled and replaced. Through the quick-release screw and the threaded sleeve, the conical block and the extrusion block are driven to move axially, thereby realizing the quick fixing and release of the limit block. This structure effectively solves the defect that the fixed connection of the traditional mold limit block is difficult to adapt to different specifications of bridge housing, improves the adaptability and maintenance efficiency of the mold, ensures the accurate positioning of the bridge housing, and reduces the leveling error caused by positioning deviation.
[0017] 2. In this utility model, two uprights are driven by a double-headed hydraulic cylinder to achieve sliding adjustment via electric slide rail one and electric slide rail two. This, together with the clamping gripper, achieves stable clamping of the axle housing body. The sliding cooperation of the slider on the slide rail allows the position of the clamping gripper to be flexibly adjusted according to the size of the axle housing. The support column provides stable support and ensures uniform clamping force. This movable clamping structure effectively prevents the axle housing from shifting and deforming during the leveling process, improves the alignment accuracy of the pressure mold and the consistency of leveling, and enhances the versatility of the mold and production efficiency.

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.
[0026] Reference Figures 1-5 An embodiment of this utility model is provided: a driving bridge housing pipa hole surface leveling mold, including a bracket 1. The bracket 1 provides a basic support structure for the entire mold, which is used to support the base 2 and the upper components to ensure the stability of the mold structure. The base 2 is fixedly connected to the upper surface of the bracket 1. An electric slide rail 3 is fixedly connected to the upper surface of the base 2. The electric slide rail 3 is set on the base 2 and a slider 6 is slidably connected on it to realize the adjustment of the clamping components moving back and forth in the horizontal direction. A stand 17 is fixedly connected to the upper surface of the electric slide rail 3. A quick-release component is provided inside the stand 17.
[0027] The quick-release assembly includes a limiting block 24, which is located outside the support frame 17. The support frame 17 supports the quick-release assembly and the limiting structure, and provides an installation positioning reference for the bridge housing body 8. A threaded sleeve 20 is fixedly connected to the outer wall of the support frame 17, and a quick-release screw 19 is threadedly connected to the inner wall of the threaded sleeve 20. The rotation of the quick-release screw 19 can drive the conical block 22 and the pressing block 23 to realize the quick release or locking of the limiting block 24, which facilitates the replacement of the limiting structure. One end of the quick-release screw 19 is fixedly connected to the conical block 22, and the pressing block 23 is slidably connected to the outer wall of the conical block 22. The pressing block 23 is connected to the outside of the conical block 22 and connected to the limiting block 24, undertaking the transmission process of clamping or releasing action. The limiting block 24 is fixedly connected to the outer wall of the pressing block 23, and a fixing block 21 is slidably connected to the outer wall of the threaded sleeve 20.
[0028] Reference Figures 1-5 A slider 6 is slidably connected to the upper surface of the electric slide rail 3. A double-headed hydraulic cylinder 18 is mounted on the slider 6 to achieve smooth sliding adjustment in the left and right directions in conjunction with the electric slide rail. The double-headed hydraulic cylinder 18 is fixedly connected to the upper surface of the slider 6. The two output ends of the double-headed hydraulic cylinder 18 are respectively connected to two uprights 17, which are used to simultaneously drive the two uprights 17 to clamp or open laterally. The two output ends of the double-headed hydraulic cylinder 18 are respectively fixedly connected to two uprights 17. A slider 9 is fixedly connected to the outer wall of the uprights 17. An electric slide rail 7 is slidably connected to the outer wall of the slider 9. A clamping gripper 10 is fixedly connected to the outer wall of the slider 9. The clamping gripper 10 is used to clamp the two sides of the bridge housing body 8 to achieve stable fixation and prevent the workpiece from shifting or sliding during the pressing process. A support column 25 is fixedly connected to the lower surface of the electric slide rail 2. A side plate 4 is fixedly connected to the outer wall of the base 2. A hydraulic rod 5 is fixedly connected to the upper surface of the side plate 4. The hydraulic rod 5 is vertically set. The hydraulic rod 5 is used to drive the leveling mold body 16 to move up and down, so as to realize the flattening operation of the bridge housing end face. The output end of the hydraulic rod 5 is fixedly connected to the connecting plate 12. The outer wall of the connecting plate 12 is fixedly connected to the limit rod 13. The outer wall of the connecting plate 12 is fixedly connected to the protective sleeve 14. The bottom of the inner wall of the protective sleeve 14 is fixedly connected to the motor 15. The output end of the motor 15 is fixedly connected to the leveling mold body 16. The leveling mold body 16 directly contacts the pipa hole end face of the bridge housing body 8. The locally warped end face is flattened by pressure. One end of the limit rod 13 is fixedly connected to the inner wall of the side plate 4. The upper surface of the support 17 is fixedly connected to the positioning block 11. The upper surface of the support 17 is fixedly connected to the bridge housing body 8. The driving bridge housing workpiece to be processed on the bridge housing body 8 needs to be positioned and leveled by this mold. The outer wall of the bridge housing body 8 is fixedly connected to the inner wall of the positioning block 11. The outer wall of the bridge housing body 8 is fixedly connected to the outer wall of the clamping gripper 10.
[0029] Working principle: When a driving axle housing vent leveling mold is needed, the driving axle housing is first placed manually or mechanically on the mold stand 17. The stand 17 is equipped with a positioning block 11 to limit the position and posture of the axle housing, ensuring that the vent end face of the axle housing body 8 is directly below the pressure mold to avoid uneven pressure. Under the action of the hydraulic rod 5, motor 15 and leveling mold body 16, the upper pressure mold contacts the vent end face of the leveling mold. By gradually applying uniform pressure, the local warped deformation area is leveled. After leveling is completed, the leveling mold body 16 moves upward to reset, releasing the clamping mechanism. The worker removes the leveled axle housing body 8, completing one correction cycle. When it is necessary to change to a different model of axle housing body 8 for leveling operations, the operator rotates the quick-release screw 19. This screw drives the tapered... The cone block 22 moves axially, and the cone block 22 further pushes the external extrusion block 23, causing the limiting block 24 to move, so that the limiting block 24 enters the fixed block 21. The fixed block 21 is fixed inside the electric slide rail 3, so that the electric slide rail 3 is fixed to the stand 17. When disassembly is required, the quick-release screw 19 can be rotated in the reverse direction, so that the quick-release screw 19 drives the cone block 22 to move vertically, causing the extrusion block 23 to retract, and at the same time, the limiting block 24 also retracts into the threaded sleeve 20, so as to quickly disassemble the electric slide rail 3 and the stand 17. Since the positioning block 11 is fixed on the stand 17, the positioning block 11 can be quickly replaced. This structure solves the problem of the traditional mold limiting structure being fixed and difficult to adapt to different bridge housing sizes, improves the mold's adaptability and replacement efficiency, and avoids the problem of positioning deviation caused by structural mismatch.
[0030] Furthermore, after the axle housing body 8 is positioned, the double-headed hydraulic cylinder 18 is controlled to work, and its two output ends push the two uprights 17 to move left and right along the electric slide rail 2 7. The slider 2 9 slides on the electric slide rail 2 7, so that the two clamping grippers 10 are brought closer to the outer walls of both sides of the axle housing body 8 under the guidance of the electric slide rail 2 7, so as to achieve stable clamping. The slider 1 6 slides horizontally on the electric slide rail 1 3, so that the clamping grippers 10 can flexibly adjust their positions according to the size of the axle housing, thereby completing the universal clamping and positioning of multiple axle housing models. The support column 25 provides stable support and ensures uniform force. This movable clamping structure can effectively avoid the leveling error caused by incomplete clamping, workpiece offset or deformation, further improve the positioning accuracy and leveling consistency of the mold, and at the same time reduce the dependence on manual operation, improve the flexibility and efficiency of the mold in production.
