Description

Technical Field

[0001] The invention relates to the technical field of welding devices, and in particular to a welding device for multi-variety non-standard parts of special-purpose vehicles. Background Art

[0002] Special-purpose vehicles refer to a type of vehicle that is specifically used for a specific purpose or task. They can be divided into many types according to different usage scenarios and functional requirements, such as engineering vehicles, fire trucks, etc. Their performance, functions and designs vary greatly. Since the needs of each industry are different, the design and production of special-purpose vehicles need to be carried out in a targeted manner. This also requires special-purpose vehicle manufacturers to have strong customization and service capabilities to meet the different needs of customers.

[0003] Non-standard automotive parts mainly include engine system parts, transmission system parts and chassis system parts. Transmission system parts are mainly used to connect and transmit power between various components, and transmission system parts are mainly composed of shaft-type automotive parts. Because each car model and configuration are different, this means that each car requires specific shaft-type parts to meet its specific needs, so shaft-type automotive parts are usually non-standard parts. These parts include bearing seats, universal joints, differential cases, half shafts, etc.

[0004] These automotive parts need to follow specific process principles during the actual production and assembly process, the most important of which is welding, which is one of the commonly used connection methods in the machinery manufacturing industry. For non-standard automotive parts such as shafts, welding can not only form a firm connection between parts, but also effectively solve the problem of fitting clearance between parts, thereby improving the operating reliability and stability of the entire vehicle.

[0005] When welding shafts and automotive parts with certain curved surfaces, the welding gun needs to move along the contour of the parts. However, due to the complex shape of automotive parts, factors such as the stability of the welding gun and the technical level of the operator, the movement trajectory of the welding gun may deviate from the predetermined welding path, resulting in inconsistency between the welding position of the welding gun and the part during the welding process, resulting in uneven welding, which in turn affects the strength and stability of the welded joint.

DETAILED DESCRIPTION

[0095] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0096] like Figures 1 to 13 As shown, this embodiment proposes a welding device for multi-variety non-standard parts of special-purpose vehicles, including a machine tool 1, a supporting frame 2 is fixedly installed on the back of the machine tool 1, and also includes a loading platform 3, a bearing component, a sliding groove 4, an adaptive clamping component, a lateral adjustment component, an angle offset component, a mounting frame 5 and a welding component. The loading platform 3 is arranged on the machine tool 1, and the loading platform 3 is slidably matched with the machine tool 1. The bearing component is installed inside the machine tool 1 for supporting the loading platform 3. The bearing component includes a bearing frame 6, an arc frame 7 and a guide block 8. Two bearing frames 6 are symmetrically and fixedly installed inside the machine tool 1, and two arc frames 7 are symmetrically and fixedly installed at the bottom of the loading platform 3. The two arc frames 7 are respectively slidably matched with the two bearing frames 6, and guide blocks 8 are fixedly installed at the four corners of the loading platform 3.

[0097] Specifically, when welding automobile parts, first measure the parts to be welded, determine the size of the parts, turn on the lateral adjustment component, move the adaptive clamping component to the clamping position, then place the parts to be welded on the adaptive clamping component and fix them, then turn on the welding component to weld them. During the welding process of the curved surface, the welding position can be automatically adjusted by the welding component to weld them. At the same time, the lateral adjustment component can drive the automobile parts to move along the position of the sliding groove 4, and in order to improve the welding efficiency, the angle of the loading platform 3 can also be adjusted by setting the angle offset component. The loading platform 3 drives the arc frame 7 to rotate. At this time, relative sliding occurs between the arc frame 7 and the supporting frame 6, thereby improving the stability during the adjustment process. The guide block 8 is set to avoid the loading platform 3 from being stuck, which facilitates welding and improves the welding quality.

[0098] like Figure 4 , Figure 5 As shown, a plurality of sliding grooves 4 are provided on the loading platform 3 at equal distances, and an adaptive clamping assembly is installed on the sliding groove 4 for clamping parts of different varieties. The adaptive clamping assembly comprises a sliding frame 9, an arc-shaped clamping seat 10, an arc-shaped sliding groove 11, a slider 12, a clamping claw 13 and a clamping portion.

[0099] Specifically, after adjusting the position of the sliding frame 9, the clamping part can be opened, and the position of the slider 12 can be adjusted according to the size of the parts to improve the stability of the clamping. When the slider 12 moves to the specified position along the arc-shaped slide groove 11, the parts to be welded are placed on the arc-shaped clamping seat 10. At this time, the parts are in contact with the clamping claws 13, and the clamping claws 13 automatically rotate with the slider 12 to adapt to the shape of the automobile parts, thereby facilitating the stable clamping of the automobile parts. Then, after clamping the automobile parts, the welding operation can be started.

[0100] The above, such as Figure 5As shown, the clamping part includes a partition 14, a first electric cylinder 15, a sliding frame 16, a connecting frame 17 and a second electric cylinder 18.

[0101] Specifically, when adjusting the position of the slider 12, the first electric cylinder 15 is turned on, the first electric cylinder 15 drives the sliding frame 16 to move, and the sliding frame 16 drives the connecting frame 17 to move, thereby pushing the corresponding slider 12 to move through the connecting frame 17. At this time, relative rotation occurs between the slider 12 and the connecting frame 17, and relative movement occurs between the connecting frame 17 and the sliding frame 16, thereby driving the slider 12 to move on the arc-shaped slide groove 11 until the position of the corresponding slider 12 is adjusted. The first electric cylinder 15 can be closed and locked, and after the parts are placed on the corresponding clamping claws 13, the corresponding second electric cylinder 18 is turned on, thereby driving the corresponding clamping claws 13 to move until the clamping claws 13 on the output end of the second electric cylinder 18 contact the automobile parts and cooperate with the clamping claws 13 on the slider 12 to fix the automobile parts, and then the second electric cylinder 18 can be closed and locked.

When welding shafts or automobile parts with a certain arc surface, the fifth motor 49 is started, and the fifth motor 49 drives the driving gear 50 to rotate, thereby driving the slide 46 to move on the semicircular frame 45 through cooperation with the semi-gear ring 48. The position adjustment between the welding device body 37 and the slide 46 by the fourth electric cylinder 47 can make the moving position of the welding gun more closely fit the welding position, thereby improving the welding quality.

[0117] In addition, in order to improve the welding efficiency, the angle of the loading platform 3 can also be adjusted. At this time, the third motor 35 is started, and the third motor 35 drives the driving shaft 34 to rotate, thereby driving the two transmission gears 36 to rotate through the driving shaft 34, and the corresponding half gear 33 can be driven to rotate, so that the position of the loading platform 3 can be adjusted. The loading platform 3 drives the arc frame 7 to rotate. At this time, relative sliding occurs between the arc frame 7 and the supporting frame 6, thereby improving the stability during the adjustment process. Through the setting of the guide block 8, the loading platform 3 can be prevented from being stuck, which facilitates welding and improves the welding quality.

[0118] At the same time, the first motor 21 is started, the first motor 21 drives the first screw rod 20 to rotate, and the first screw rod 20 drives the corresponding first nut 23 to move. The movement of the first nut 23 can drive the displacement box 22 to move, thereby driving the adjustment frame 24 to move. The adjustment frame 24 drives the two sliding frames 9 to move on the sliding groove 4 at the same time, which can drive the automobile parts to move during the welding process, adjust the welding position, and thus improve the welding efficiency.
