Description

Technical Field

[0001] This invention belongs to the technical field of axle processing, specifically a friction welding connection device for half-shaft sleeves and axle housings. Background Technology

[0002] As key components of the automotive drive axle, the axle sleeve and axle housing bear the brunt of torque transmission, impact loads, and radial loads during vehicle operation. The strength, sealing, and coaxiality of their connection directly affect the service life of the drive axle and driving safety. Friction welding, as a high-quality and efficient solid-state joining technology, offers significant advantages such as a dense weld interface, absence of porosity and slag inclusions, high joint strength, minimal thermal deformation, fast production cycle, and strong process stability. It has been widely applied in the automated welding production of axle sleeves and axle housings, becoming the mainstream joining process for these heavy-duty components.

[0003] However, existing friction welding equipment for axle housings and half-shaft sleeves generally suffers from the following problems in practical applications: the axle housing is large in size, heavy in weight, and long in length. Existing equipment requires the axle housing to be directly hoisted and aligned with the central clamping mechanism and the welding units of the sleeves on both sides. During the assembly process, the workpiece is prone to shaking and displacement, making it difficult to align successfully in one go. It requires manual support and adjustment of posture multiple times, which is not only labor-intensive but also poses safety hazards. Furthermore, the single-station sequential loading and unloading mode requires waiting for the workpiece to exit the fixture after welding before the next workpiece can be clamped. It is impossible to achieve simultaneous welding and material preparation, resulting in long equipment waiting time, slow overall production cycle, and difficulty in meeting the needs of large-scale continuous production. Summary of the Invention

[0004] This invention provides a friction welding connection device for axle sleeve and axle housing, which can solve the technical problems of high labor intensity and low material loading and unloading efficiency when the connection device adopts the hoisting and loading method in the prior art.

[0005] A friction welding connection device for a half-shaft sleeve and an axle housing includes a support box. Pushing mechanisms are provided on both sides of the support box. A flipping and fixing mechanism is provided inside the support box. A receiving mechanism is fixed at the front and rear of the support box. A clamping mechanism is movably installed on the top of the support box on both sides of the flipping and fixing mechanism.

[0006] As a further technical solution of the present invention, the clamping mechanism includes a movable box, the middle part of which is recessed, and positioning blocks are movably installed on both sides of the recess.

[0007] As a further technical solution of the present invention, the front and rear edges of the top of the support box are fixed with moving rails, the bottom of the moving box is slidably connected to the moving rails, and a pushing hydraulic rod is fixed to the rear wall of the support box. The pushing hydraulic rod is fixed to the support box through a connecting plate.

[0008] As a further technical solution of the present invention, the pushing mechanism includes an L-shaped plate fixed to the support box, a hydraulic cylinder fixed to the outside of the L-shaped plate, a motor box provided on the inside of the L-shaped plate, a hydraulic chuck provided on the outside of the motor box, a guide rail fixed to the top surface of the L-shaped plate, and the bottom of the motor box slidably connected to the guide rail.

[0009] As a further technical solution of the present invention, the flipping and fixing mechanism includes a flip plate located on the top surface of the support box and a bottom plate located inside the support box. A first bearing seat is fixed at the bottom center line and both sides of the flip plate, and a second bearing seat is fixed at the top center of the bottom plate. A folding rod is connected to the adjacent ends of the first and second bearing seats. One end of the folding rod is fixedly connected to the shaft of the second bearing seat, and the other end of the folding rod is movably connected to the shaft of the first bearing seat. The folding part of the folding rod is connected by a rotating shaft. A drive housing is fixed at the bottom center of the bottom plate, and a limit block is fixed at the ends of the first bearing seats on both sides of the top surface of the bottom plate. A limit rod for limiting the shaft of the first bearing seat is also provided on the top surface of the bottom plate.

[0010] As a further technical solution of the present invention, the top surface of the limiting block is provided with an arc-shaped groove, and a limiting groove is provided at one corner of the limiting block. The drive shaft of the drive housing passes through the top surface of the base plate and is fixed with an active bevel gear. The shaft of the second shaft seat is fixed with a driven bevel gear, and the driven bevel gear meshes with the active bevel gear.

[0011] As a further technical solution of the present invention, a fixing plate is fixed to the bottom of the limiting rod, and a hydraulic push rod is connected to one side of the fixing plate. The bottom surface of the fixing plate is fixed to the top surface of the base plate, and the hydraulic push rod is fixed to the top surface of the base plate. The limiting rod is located on one side of the limiting block.

[0012] As a further technical solution of the present invention, a supporting chassis is fixed at the center of the top surface of the flip plate, and vertical plates are fixed on both sides of the top surface of the flip plate located on the supporting chassis. Clamping blocks are slidably connected inside the vertical plates, and positioning hydraulic rods for driving the clamping blocks to move are installed on the vertical plates.

[0013] As a further technical solution of the present invention, the receiving mechanism includes a lower plate fixed to the support box, an upper plate slidably mounted on the upper part of the lower plate via a slide rail, two parallel receiving hydraulic rods fixed on the top of the upper plate, and a receiving seat fixedly connected to the top of the receiving hydraulic rods.

[0014] As a further technical solution of the present invention, a translational hydraulic rod is fixed on the bottom surface of the lower plate, and a connecting rod is connected between the end of the translational hydraulic rod and the upper plate. A support frame is fixed on the outside of the support box, and the support frame is supported on the bottom of the lower plate.

[0015] The beneficial effects of this invention are: This invention, through the setting of a flipping and fixing mechanism in cooperation with a receiving mechanism, flips the flap and then uses the receiving seat on the receiving hydraulic rod to receive the axle shell. After the flap flips, the axle shell can be moved between two clamping blocks for clamping by moving the upper plate. After the flap is rotated to a horizontal state, friction welding can be performed. Therefore, during axle shell assembly, it is only necessary to hoist it onto the receiving seat for receiving, without having to hoist the axle shell onto the clamping mechanism and between the two clamping blocks. This makes the axle shell assembly more labor-saving and effectively avoids the situation where the axle shell shakes during assembly, requiring frequent manual support, and causing damage due to collision with the corresponding clamping structure. After the axle housing and the half-shaft sleeve are welded, they are supported by another receiving mechanism. After the two receiving seats support both ends of the axle housing, the two clamping blocks can be contacted to fix the middle of the axle housing. With the help of the translation hydraulic rod, the upper plate is moved to send the axle housing out between the two clamping blocks. After the friction welding is completed, the axle housing can be lifted out of the two receiving seats without having to be taken out of the clamping structure, making the operation more convenient. Furthermore, during the friction welding of the axle housing, another axle housing can be assembled onto the two bearing seats for preparation. After the welding of the previous axle housing is completed, the next axle housing can be quickly put into the welding process, which effectively improves work efficiency.

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1 - Figure 6 As shown, a friction welding connection device for a half-shaft sleeve and a bridge housing includes a support box 1. Pushing mechanisms 2 are provided on both sides of the support box 1. A flipping and fixing mechanism 3 is provided inside the support box 1. A receiving mechanism 4 is fixed at the front and rear of the support box 1. A clamping mechanism 5 is also movably installed on the top of the support box 1 on both sides of the flipping and fixing mechanism 3.

[0020] The clamping mechanism 5 includes a movable housing with a concave center and positioning blocks movably mounted on both sides of the concave portion. Movable rails are fixed to the front and rear edges of the top of the support housing 1. The bottom of the movable housing is slidably connected to the movable rails. A pushing hydraulic rod is fixed to the rear wall of the support housing 1, and the pushing hydraulic rod is fixed to the support housing 1 via a connecting plate.

[0021] Specifically, the flipping and fixing mechanism 3 fixes the middle part of the axle housing, pushes the hydraulic rod to move the moving box closer to the flipping and fixing mechanism 3, adapts to the distance between the two ends of the axle housing, and uses positioning blocks to fix the two ends of the axle housing, so that the middle and both ends of the axle housing are in a fixed state.

[0022] The pushing mechanism 2 includes an L-shaped plate fixed to the support box 1. A hydraulic cylinder is fixed to the outside of the L-shaped plate, a motor box is provided on the inside of the L-shaped plate, a hydraulic chuck is provided on the outside of the motor box, a guide rail is fixed to the top surface of the L-shaped plate, and the bottom of the motor box is slidably connected to the guide rail.

[0023] Specifically, in the pushing mechanism 2, the hydraulic chuck fixes the end of the half-shaft sleeve. The motor box drives the hydraulic chuck to rotate, and the hydraulic cylinder pushes the hydraulic chuck to move. Pressure is applied when the half-shaft sleeve rotates and rubs against the end of the axle housing to achieve welding fixation.

[0024] The flipping and fixing mechanism 3 includes a flip plate 301 located on the top surface of the support box 1 and a base plate 307 located inside the support box 1. A first bearing seat 305 is fixed to the bottom centerline and both sides of the flip plate 301. A second bearing seat 309 is fixed to the top center of the base plate 307. Folding rods 306 are connected to the adjacent ends of both the first and second bearing seats 305. One end of the folding rod 306 is fixedly connected to the shaft of the second bearing seat 309, and the other end is movably connected to the shaft of the first bearing seat 305. The folding portion of the folding rod 306 is connected via a rotating shaft. A drive housing 308 is fixed to the bottom center of the base plate 307, and limit blocks 310 are fixed to the top surface of the base plate 307 and the ends of the first bearing seats 305 on both sides. The top surface of the base plate 307 is also provided with a limiting rod 311 for limiting the shaft of the first shaft seat 305. The top surface of the limiting block 310 is provided with an arc-shaped groove 312, and a limiting groove 313 is provided at one corner of the limiting block 310. The drive shaft of the drive housing 308 passes through the top surface of the base plate 307 and is fixed with a driving bevel gear. The shaft of the second shaft seat 309 is fixed with a driven bevel gear, which meshes with the driving bevel gear. The bottom of the limiting rod 311 is fixed with a fixing plate 314, and a hydraulic push rod 315 is connected to one side of the fixing plate 314. The bottom surface of the fixing plate 314 is fixed to the top surface of the base plate 307, and the hydraulic push rod 315 is fixed to the top surface of the base plate 307. The limiting rod 311 is located on one side of the limiting block 310. Specifically, the drive housing 308 drives the active bevel gear to rotate, which in turn drives the driven bevel gear to rotate, thereby driving the second shaft seat 309 to rotate. The rotation of the second shaft seat 309 drives the folding rod 306 to unfold from the folded state. According to the rotation requirements of the flip plate 301, the hydraulic push rod 315 pushes the limit rod 311 to release the restriction on the first shaft seat 305 away from the rotation direction. The first shaft seat 305 on the rotating side is limited by the limit rod 311 and the limit block 310. As the folding rod 306 unfolds and flips, the bridge housing can be flipped to the position above the receiving mechanism 4.

[0025] A support chassis 304 is fixed to the center of the top surface of the flip plate 301, and vertical plates 302 are fixed on both sides of the top surface of the flip plate 301 located on the support chassis 304. A clamping block 303 is slidably connected inside the vertical plate 302, and a positioning hydraulic rod for driving the clamping block 303 to move is installed on the vertical plate 302.

[0026] Specifically, the bottom center of the axle housing is supported by a support chassis 304, and the clamping blocks 303 on both sides are clamped by positioning hydraulic rods, thereby fixing the center of the axle housing.

[0027] The receiving mechanism 4 includes a lower plate 401 fixed to the support box 1. An upper plate 402 is slidably mounted on the upper part of the lower plate 401 via a slide rail 403. Two parallel receiving hydraulic rods 404 are fixed on the top of the upper plate 402, and a receiving seat 405 is fixedly connected to the top of the receiving hydraulic rods 404. A translation hydraulic rod 407 is fixed on the bottom surface of the lower plate 401, and a connecting rod 406 is connected between the end of the translation hydraulic rod 407 and the upper plate 402. A support frame is fixed on the outside of the support box 1, and the support frame supports the bottom of the lower plate 401.

[0028] Specifically, after the welded bridge housing is flipped to a vertical position by the flip plate 301, the two receiving hydraulic rods 404 are extended, which drive the receiving seats 405 to support the two ends of the bridge housing. At this time, the middle part of the bridge housing is released from the fixation, and the bridge housing can be removed.

[0029] This invention discloses a friction welding connection device for a half-shaft sleeve and an axle housing. In use, the unwelded axle housing is first placed on the rear receiving mechanism 4. The distance between the two receiving hydraulic rods 404 in the rear receiving mechanism 4 is preset to match the width of both ends of the axle housing. The receiving seats 405 support both ends of the axle housing. Then, the driving flip plate 301 is rotated towards the axle housing. The driving housing 308 drives the active bevel gear to rotate, which in turn drives the driven bevel gear to rotate, thereby driving the second shaft seat 309 to rotate. The rotation of the second shaft seat 309 drives the folding rod 306 to unfold from the folded state. The hydraulic push rod 315 pushes the limiting rod 311 to release the restriction on the first shaft seat 305 away from the rotation direction. The first shaft seat 305 on the rotating side is limited by the limiting rod 311 and the limiting block 310. As the folding rod 306 unfolds and flips, the axle housing can be flipped to the position above the receiving mechanism 4. At this point, by extending and moving the hydraulic rod 404, the middle part of the axle housing is sent between the two vertical plates 302 and fixed by the clamping block 303, thus realizing the assembly of the axle housing.

[0030] During welding, the hydraulic chuck fixes the end of the half-shaft sleeve. The motor box drives the hydraulic chuck to rotate, and the hydraulic cylinder pushes the hydraulic chuck to move. Pressure is applied when the half-shaft sleeve rotates and rubs against the end of the axle housing to achieve welding fixation.

[0031] After welding is completed, release the hydraulic chuck from the half-shaft sleeve and reset the hydraulic chuck. At the same time, release the positioning block from the end of the axle housing and flip the flap 301 above the other receiving mechanism 4. At this time, only the middle part of the axle housing is fixed. By extending the receiving hydraulic rod 404 and cooperating with the movement of the upper plate 402, the receiving seat 405 is supported on both ends of the welded axle housing. Release the fixation on the middle part of the axle housing, and the welded axle housing can be removed. At this time, simply lift the axle housing until it is detached from the receiving seat 405 to remove it.

[0032] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
