Description

Technical Field

[0001] This invention relates to the field of automotive axle welding technology, specifically to an automotive axle welding device. Background Technology

[0002] The axle of a car is connected to the chassis via the suspension, and wheels are mounted at both ends of it. The axle's function is to bear the load of the car and maintain its normal driving on the road. It is one of the key components of a car, and the quality of its welding is related to the safety of the car.

[0003] Current automotive axle welding methods typically involve placing the axle main housing and then connecting it to the axle housing at both ends. A ring weld is then performed at the connection point between the axle main housing and the axle housing. One end cap on the end face of the axle main housing also requires a ring weld. Since the axle housing undergoes a longitudinal plane ring weld while the end cap undergoes a horizontal plane ring weld, the welding positions differ, often requiring multiple steps. This not only reduces processing efficiency but also necessitates separate positioning, compromising welding quality. Summary of the Invention

[0004] The technical problem to be solved by this invention is that the circumferential welding planes of the axle main housing and the axle housing and the circumferential welding planes of the axle main housing and the end cover are perpendicular to each other, and the circumferential welding positions of the two are different. They are mostly carried out in multiple steps, which not only reduces the processing efficiency, but also requires separate positioning and cannot guarantee the welding effect.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: an automotive axle welding device, comprising a welding seat, a first welding head, and a second welding head. The welding seat has a bearing plate in the middle, and limiting seats are slidably provided on both sides of the bearing plate. The welding seat is provided with a driving component that can drive the limiting seats to slide relative to each other so that the two ends of the axle main housing and the axle housing can be aligned and locked together. The welding seat has a first circumferential welding component at the connection between the end of the axle main housing and the axle housing, and the first welding head is provided on the first circumferential welding component. The welding seat is provided with a gantry frame, and a fixing plate is provided in the middle of the gantry frame. The fixing plate is provided with a limiting component that can stably limit the end cover and the axle main housing, and a second circumferential welding component that can weld the axle main housing and the end cover.

[0006] Furthermore, the driving assembly includes sliding grooves on both sides of the welding seat, a slider at the bottom of the limiting seat that slides with the sliding groove, and a bidirectional screw that rotates through the sliding groove. The bidirectional screw passes through the slider via a thread.

[0007] Furthermore, the free end face of the limiting seat is provided with a conical limiting block that can fit with shaft housings of different diameters.

[0008] Furthermore, the first ring welding assembly includes a hollow incomplete ring seat with a gap between the ends of the incomplete ring seat. An arc plate is slidably provided inside the incomplete ring seat. The first welding head is located on the inner side of the arc plate. A gear ring is provided on the outer side of the arc plate. Gears one that mesh with the gear ring are respectively provided on both sides inside the incomplete ring seat. The gears one are driven by a driving component.

[0009] Furthermore, the driving component includes a first motor mounted on an incomplete ring seat. The power output end of the first motor is provided with a driving wheel. The driving wheel is symmetrically provided with a driven wheel on the other side of the incomplete ring seat via a synchronous belt. The driving wheel and the driven wheel are respectively provided with a second gear on the same axis. The second gear meshes with the first gear. A connecting shaft that rotates through the incomplete ring seat is provided between the first gear relative to the incomplete ring seat.

[0010] Furthermore, the limiting component includes a telescopic cylinder mounted on a fixed plate, the power end of the telescopic cylinder being provided with a limiting plate, and the limiting plate being disposed opposite to the end cap.

[0011] Furthermore, the second ring welding assembly includes a second motor mounted on a fixed plate. The power output end of the second motor rotates through the fixed plate and is provided with a gear three at its end. The fixed plate is provided with an annular groove, and an annular plate extending from the fixed plate is slidably mounted in the annular groove. A toothed ring that meshes with the gear three is provided on the outer periphery of the annular plate. The second welding head is located at the bottom end of the annular plate and its end is circumferentially oriented toward the end cover.

[0012] The advantages of this invention compared to the prior art are:

[0013] 1. By placing the axle main housing on the bearing plate, and then snapping the axle housing onto both ends of the axle main housing, the drive assembly drives the limiting seats to move closer to each other, so as to stably snap and limit the connection between the two ends of the axle main housing and the axle housing, so that the axle main housing can be centered and avoid displacement of the axle main housing or the snapping point between the axle main housing and the axle housing during subsequent welding, which would affect the welding effect; the setting of the first ring welding assembly on both sides facilitates the drive of the first welding head to perform ring welding operation on the connection between the axle main housing and the axle housing at the same time;

[0014] 2. The setting of the limiting component makes it easy to stably limit the end cover and the axle main shell. Then, the second welding head can be driven by the second circumferential welding component to perform circumferential welding between the end cover and the axle main shell, which can improve welding efficiency.

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

[0023] Combined with appendix Figure 1 Appendix Figure 2 and attached Figure 3 A welding device for automobile axles includes a welding seat 1, a first welding head 2 and a second welding head 3. The welding seat 1 is provided with a bearing plate 4 in the middle. Limiting seats 5 are slidably provided on both sides of the bearing plate 4. The free end face of the limiting seat 5 is provided with a conical limiting block 15 that can cooperate with axle housings of different diameters.

[0024] Combined with appendix Figure 3 The welding seat 1 is provided with a drive assembly 6 that can drive the limiting seat 5 to slide relative to each other so that the two ends of the axle main housing and the axle housing can be aligned and locked together. The drive assembly 6 includes a sliding groove 12 on both sides of the welding seat 1. The bottom end of the limiting seat 5 is provided with a slider 13 that slides with the sliding groove 12. A bidirectional screw 14 is rotatably passed between the relative sliding groove 12. The bidirectional screw 14 is set to pass through the slider 13 by thread.

[0025] First, place the axle main housing horizontally on the bearing plate 4, and snap the axle housing to both ends of the axle main housing respectively;

[0026] Then, by driving the bidirectional screw 14, the bidirectional screw 14 drives the slider 13 through the threaded connection with the slider 13, causing the limiting seat 5 to slide relative to the slide groove 12. The limiting seat 5 can lift the ends of the axle housings of different diameters inward through the conical limiting block 15, thereby making the axle main housing and the axle housing collinear and making both sides symmetrical and stable, avoiding workpiece displacement during welding and affecting the welding effect.

[0027] Combined with appendix Figure 2 Appendix Figure 4 and attached Figure 5 The welding seat 1 is provided with a first ring welding assembly 7 at the connection between the end of the axle main housing and the axle housing. The first welding head 2 is provided on the first ring welding assembly 7. The first ring welding assembly 7 includes a hollow incomplete ring seat 16. There is a gap between the ends of the incomplete ring seat 16. An arc plate 17 is slidably provided inside the incomplete ring seat 16. The first welding head 2 is provided inside the arc plate 17. A gear ring 18 is provided outside the arc plate 17. Gears 19 that mesh with the gear ring 18 are provided on both sides inside the incomplete ring seat 16. The gears 19 are driven by the driving component.

[0028] Combined with appendix Figure 2 and attached Figure 5 The driving component includes a first motor 20 mounted on an incomplete ring seat 16. The power output end of the first motor 20 is provided with a driving wheel 21. The driving wheel 21 is symmetrically provided with a driven wheel 22 on the other side of the incomplete ring seat 16 via a synchronous belt. The driving wheel 21 and the driven wheel 22 are respectively coaxially provided with a second gear 23. The second gear 23 meshes with a first gear 19. A connecting shaft 24 that rotates through the incomplete ring seat 16 is provided between the first gear 19 and the incomplete ring seat 16.

[0029] By starting the first motor 20, the first motor 20 drives the driving wheel 21, which in turn drives the driven wheel 22 via a synchronous belt, thereby causing the gears 23 on both sides to rotate synchronously. Since gear 23 meshes with gear 19 and gear 19 meshes with the gear ring 18, as long as the angle between the end of the arc plate 17 and the axis of the arc plate 17 is less than the angle between the gears 23 on both sides and the axis of the arc plate 17, the arc plate 17 can drive the first welding head 2 to perform circumferential welding.

[0030] Combined with appendix Figure 6The welding seat 1 is provided with a gantry frame 8, and a fixing plate 9 is provided in the middle of the gantry frame 8. The fixing plate 9 is provided with a limiting component 10 that can stably limit the end cover and the main shell of the axle, and a second ring welding component 11 that can weld the main shell of the axle and the end cover. The limiting component 10 includes a telescopic cylinder 25 provided on the fixing plate 9. The power end of the telescopic cylinder 25 is provided with a limiting plate 26, which is positioned opposite the end cover. The second ring welding component 11 includes a second motor 27 provided on the fixing plate 9. The power output end of the second motor 27 rotates through the fixing plate 9 and is provided with a gear 3 28 at its end. The fixing plate 9 is provided with an annular groove. An annular plate 29 extending the fixing plate 9 is slidably provided in the annular groove. A toothed ring 30 that meshes with the gear 3 28 is provided on the outer periphery of the annular plate 29. The second welding head 3 is provided at the bottom end of the annular plate 29 and its end is circumferentially facing the end cover.

[0031] After the drive assembly 6 aligns and positions the axle main housing and the axle housing, the axle main housing is located in the middle of the bearing plate 4. The end cover is then fitted with the axle main housing. At this time, the end cover is coaxial with the ring plate 29, which makes it easier for the second welding head 3 to be aligned with the circumferential direction of the end cover for welding.

[0032] By activating the telescopic cylinder 25 to extend, the telescopic cylinder 25 drives the limiting plate 26 to abut against the end cover, thereby achieving stable positioning of the end cover.

[0033] Then, by starting the second motor 27, the second motor 27 drives the gear 3 28, and the gear 3 28 drives the ring plate 29 through meshing with the gear ring 30 to drive the second welding head 3 to perform circumferential welding operation on the end cover synchronously, thereby improving the welding efficiency.
