Description

Technical Field

[0001] This invention relates to the field of non-cutting machining technology for metal pipes, specifically to a deformation correction device for axle half-shaft sleeves. Background Technology

[0002] The drive axle of an automobile is a device used to transmit the driving force from the engine to the drive wheels, thereby reducing speed and increasing torque, while also changing the direction of power transmission.

[0003] The axle sleeve is an important component of the automotive drive axle assembly. It is integrated with the drive axle housing to fix the axial relative position of the left and right drive wheels, together supporting the frame and the mass of the various assemblies on it. At the same time, it bears the road reaction force and torque transmitted from the wheels when the car is in motion, and transmits them to the frame through the suspension.

[0004] The existing axle sleeves are mainly of two types: integral and split. The difference between the two lies in whether the axle sleeve body and the flange are integrally formed.

[0005] After the split-type half-shaft sleeve is formed, it is directly pressed into the bridge housing from both ends.

[0006] Half-shaft sleeves are mostly made of hot-rolled seamless steel pipes of carbon structural steel and alloy steel. Their forming process mainly includes material selection, extrusion, assembly welding, and precision machining. However, since half-shaft sleeves are hollow tubes with a certain length and thin walls, they are prone to bending and torsional deformation during machining, resulting in large deviations in the formed half-shaft sleeves and affecting the quality of the finished product. Therefore, in the processing of half-shaft sleeves, a straightening process is usually added after extrusion forming and before assembly welding to compensate for the bending deformation of the parts.

[0007] However, existing equipment and processing methods, due to their limited functionality and poor specialization, generally suffer from the following problems when used for bending and straightening of axle sleeves:

[0008] 1. Limited straightening methods and poor adaptability to different deformations. Specifically, during the processing of axle sleeves, various deformations such as bending and twisting will occur. However, existing equipment is limited by a single straightening method, which can only compensate for specific deformations, resulting in poor processing adaptability and affecting the straightening effect.

[0009] 2. Inconvenient adjustment of the straightening area. Specifically, the deformation of the axle sleeve during processing is random. This means that the axle sleeve needs to be clamped differently according to the different deformed areas during the straightening process. It may even be necessary to adjust and move the axle sleeve in real time during the straightening process. However, the existing equipment used for axle sleeve bending straightening has two problems: firstly, the clamping is inconvenient; secondly, the axle sleeve cannot be adaptively moved and adjusted after clamping, which greatly reduces the straightening efficiency.

[0010] 3. It is difficult to achieve localized correction of deformation. Specifically, some localized deformations on the half-shaft sleeve cannot be corrected by overall torsional bending.

[0011] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0012] To address the shortcomings of existing technologies, this invention provides a vehicle axle sleeve deformation correction device, which solves the problems of traditional equipment and processing methods when used for axle sleeve deformation correction, such as the single correction method resulting in poor adaptability to different deformations, inconvenience in adjusting the correction location, and difficulty in achieving local correction of deformation.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] The positioning and clamping assembly in this invention enables the loading and clamping of axle axle sleeves during the straightening process, and transfers the axle axle sleeves from the longitudinal loading position to the transverse processing position by rotating the circular base. Specifically, the positioning and clamping assembly includes a circular base with two symmetrical support vertical plates. Each support vertical plate is equipped with a retractable circular clamping plate, which clamps the axle axle sleeves from both sides. An arc-shaped positioning plate is also raised and lowered on the circular base to press and position the axle axle sleeves. Furthermore, four cross-shaped support conveying wheels are rotatably mounted on the square worktable.

Overall bending correction of the axle sleeve can be performed by the longitudinal sliding of the sliding base, while local bending correction of the axle sleeve can be performed by rotating the correction positioning plate driven by the steering drive motor.

[0058] In use, the invention works as follows: First, the rolling drive motor 10 is started, which drives two longitudinally opposite support conveyor wheels 8 to rotate. The axle half-shaft sleeve to be corrected is placed longitudinally on one end of the square central platform 1. The support conveyor wheels 8 transport the half-shaft sleeve longitudinally to a specific position. The clamping telescopic cylinder 12 is extended, and the circular clamping plate 13 clamps and positions the half-shaft sleeve from both sides. The lifting telescopic cylinder 16 is then extended, driving the U-shaped lifting frame 17 to descend. The arc-shaped positioning plate 14 presses the half-shaft sleeve down and positions it. The stepper motor 6 is then started. The circular base 4 is rotated 90°, turning the half-shaft sleeve from longitudinal to transverse, and supporting it on two transversely opposite support conveyor wheels 8. Four sliding drive motors 19 are activated, driving the transverse threaded rod 20 to rotate, which in turn drives the two lateral moving seats 2 to move in opposite directions, approaching both ends of the half-shaft sleeve from both sides. When the end of the half-shaft sleeve moves between the straightening positioning plates 24, the clamping telescopic cylinder 12 is extended, using the circular clamping plate 13 to clamp the half-shaft sleeve. The middle part of the half-shaft sleeve is then clamped again using the positioning clamping assembly. The transmission drive is then activated. Motor 29 drives the main drive bevel gear 30 to rotate, which in turn drives the longitudinal threaded rod 27 to rotate circumferentially through the transmission of the auxiliary drive bevel gear 31. This, in turn, controls the sliding base 22 to slide longitudinally along the sliding limit port 21, thus performing overall bending correction on the half-shaft sleeve. The positioning clamping assembly is released from its clamping position on the half-shaft sleeve, and the bending correction position of the half-shaft sleeve is adjusted by the rotation of the support conveyor wheel 8 and the movement of the lateral moving seat 2. The steering drive motor 23 is then activated, driving the correction positioning plate 24 to rotate, thus performing partial bending correction on the half-shaft sleeve. After the bending correction is completed, adjust the position of the half-shaft sleeve so that its two ends pass through the two torsion retaining rings 32 respectively. Control the extension of the top support telescopic cylinder 34 respectively, and use the top support block 35 to support and position the half-shaft sleeve. Start the rotation drive motor 37, and the rotation drive motor 37 drives the support transmission wheel 38 to rotate, which in turn drives the torsion retaining rings 32 to rotate, twisting the half-shaft sleeve at a certain angle to correct the tortuous deformation of the half-shaft sleeve. After the correction is completed, drive the lateral moving seat 2 to move outward, control the circular base 4 to rotate, and turn the half-shaft sleeve from horizontal to vertical for unloading and picking up the part.
