[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0028] Example 1 like Figures 1 to 5 As shown, the present invention provides a tilt welding device, including a fixed base 1; an adjusting slide 2 is slidably arranged on the fixed base 1; a tilt angle adjustment assembly 3 is arranged on the side wall of the adjusting slide 2; an adjusting rod 4 movably passes through the adjusting slide 2; an adjusting disk assembly 5 is arranged on the side wall of the adjusting slide 2 away from the tilt angle adjustment assembly 3, and the two ends of the adjusting rod 4 in the length direction are respectively connected to the tilt angle adjustment assembly 3 and the adjusting disk assembly 5; the middle position of the welding gun 6 is movably connected with the adjusting rod 4, and the welding gun 6 is movably arranged on the adjusting disk assembly 5; the tilt angle adjustment assembly 3 includes a driving motor 31 arranged on the side wall of the adjusting slide 2, an active bevel gear 32 is provided on the output shaft of the driving motor 31, and a driven bevel gear 33 meshing with the active bevel gear 32 is provided at the end of the adjusting rod 4 near the driving motor 31; the adjusting disk assembly 5 includes a circular chassis 51 arranged on the side wall of the tilt angle adjustment assembly 3, a semicircular groove 52 is provided on the circular chassis 51, a circular ring 53 is provided in the semicircular groove 52, and the welding gun 6 is movably connected to the circular ring 53 and the adjusting rod 4 away from the gun head.

[0029] Before welding, the fixing base 1 is first fixed at the position where it is required, and the driving motor 31 drives the active bevel gear 32 to rotate, thereby driving the driven bevel gear 33 and the adjusting rod 4 to rotate, so that the welding gun 6 can be rotated and adjusted with the axis of the adjusting rod 4 as the axis according to the needs of the welding position (that is, relative to the circular chassis 51, the welding gun 6 can achieve an inclination angle at different positions). While the welding gun 6 is rotating, the welding gun 6 can slide on the ring 53 in the semicircular groove 52 away from the gun head end, which is conducive to keeping the position of the welding gun 6 stable during rotation; the position of the adjusting slide 2 can also be adjusted on the fixing base 1 to achieve adjustment of the position of the welding gun 6.

[0030] Example 2 Based on the first embodiment, Figure 4 As shown, a slide groove 21 is vertically provided on the fixing seat 1, and the adjusting slide plate 2 is vertically slidably provided in the slide groove 21; it is convenient to slide and adjust the position of the adjusting slide plate 2 in the slide groove 21, so as to adjust the position of the welding gun 6 according to different welding heights, thereby improving the applicability diversity; the bottom of the slide groove 21 may be provided with a lifting cylinder or a screw nut assembly that drives the adjusting slide plate 2 to move in the vertical direction (the lifting cylinder and the screw nut assembly are both existing technologies, so they are not described here).

[0031] Example 3 Based on the first embodiment, Figure 1 、 Figures 3 to 5 The cam 33 is rotated to move the adjusting rod 33 and the adjusting rod 33 is coaxial with the adjusting rod 33; the position of the adjusting rod 4 can be adjusted by sliding on the adjusting slide 2 (so that the adjusting rod 4 moves along the length direction of the axis of the driven bevel gear 33), thereby achieving the effect of adjusting the distance between the welding gun 6 and the fixed seat 1 according to the needs of the welding position, thereby improving the diversity of welding positions; at the same time, in order to fix the position of the adjusting rod 4 after sliding on the adjusting slide 2, a connecting bolt that penetrates into the adjusting rod 4 can be provided on the side wall of the adjusting disk assembly 5 (near the end of the driven bevel gear 33), that is, before the position of the adjusting rod 4 is slid on the adjusting slide 2, the connecting bolt and the adjusting rod 4 can be separated; after the position of the adjusting rod 4 is slid on the adjusting slide 2, the connecting bolt can be penetrated into the adjusting rod 4, so that the position of the adjusting rod 4 is fixed, thereby preventing the adjusting rod 4 from rotating during welding operation.

[0032] Example 4 Based on the first embodiment, Figure 1As shown, the semicircular groove 52, the circular ring 53, the circular chassis 51 and the adjusting rod 4 are coaxial; this is beneficial for maintaining the position of the welding gun 6 stable when adjusting the position of the adjusting rod 4; at the same time, the welding gun 6 can be rotated and adjusted around the axis of the adjusting rod 4 to achieve tilt angles at different positions.

[0033] Example 5 Based on the first embodiment, Figures 1 to 4 、 Figure 8 As shown, the welding gun 6 is provided with a plurality of mounting grooves 62 adapted to the adjusting rod 4 at intervals along the length direction. The adjusting rod 4 is movable through the circular chassis 51 away from the driven bevel gear 33 and inserted into the mounting groove 62 at the corresponding position. The adjusting rod 4 is also threadedly connected to the end away from the driven bevel gear 33 with a locking bolt 64. The locking bolt 64 is movable through the mounting groove 62 at the corresponding position and conflicts with the outer peripheral wall of the welding gun 6. The adjusting rod 4 is movably inserted with a limit plate 41 away from the driven bevel gear 33. The length of the limit plate 41 is greater than the radius of the semicircular groove 52, and the position of the limit plate 41 away from the end of the adjusting rod 4 is adapted to the position of the arc-shaped opening of the semicircular groove 52; a plurality of angle limiting holes 531 are evenly distributed along the circumferential direction on the circular ring 53, and two angle limiting rods 532 are movably inserted in the plurality of angle limiting holes 531. The end of the limit plate 41 away from the adjusting rod 4 is located between the two angle limiting rods 532.

[0034] When it is necessary to adjust the position of the welding gun 6 in the vertical direction, the connecting rod 63 can be removed first (i.e., the connecting rod 63 and the welding gun 6 are separated); then, according to the requirements of the installation position, the end of the adjusting rod 4 away from the driven bevel gear 33 is passed through the installation groove 62 at the corresponding position on the welding gun 6, and then the locking bolt 64 is tightened to thread the end of the adjusting rod 4 away from the driven bevel gear 33, and the locking bolt 64 is in conflict with the outer peripheral wall of the welding gun 6.

[0035] When it is necessary to adjust the inclination angle of the welding gun 6, the adjusting rod 4 can be rotated, and the welding gun 6 can be rotated simultaneously with the adjusting rod 4 to achieve inclination angle adjustment; when the welding gun 6 is rotated, if it is necessary to limit its rotation range, the position of the limit plate 41 away from the end of the adjusting rod 4 can be adapted to the position of the arc opening of the semicircular groove 52, and the two angle limit rods 532 can be inserted into the two angle limiting holes 531 respectively, and the limit plate 41 is away from the end of the adjusting rod 4 and located between the two angle limit rods 532. At this time, when the welding gun 6 is rotated, the two angle limit rods 532 can limit the limit plate 41 away from the end of the adjusting rod 4.

[0036] A notch 411 is provided at the end of the limiting plate 41 away from the adjusting rod 4, and the circular ring 53 is located in the notch 411. An extension rod 412 is provided on the notch 411, and the extension rod 412 is located between the two angle limiting rods 532; when the two angle limiting rods 532 are respectively inserted into the angle limiting holes 531 at the corresponding positions, the extension rod 412 can be maintained between the two angle limiting rods 532, so as to limit the position when the welding gun 6 is rotated and adjusted. At the same time, when the welding gun 6 is rotated, the extension rod 412 and the limiting plate 41 can rotate synchronously, and the notch 411 can move outside the circular ring 53 without interfering with the circular ring 53.

[0037] Since the limit plate 41 is movably inserted at the end of the adjusting rod 4 away from the driven bevel gear 33, when the limit plate 41 is not needed, the limit plate 41 can be slid and adjusted to the position at the end of the adjusting rod 4 away from the driven bevel gear 33, so that the distance from both ends of the limit plate 41 in the length direction to the adjusting rod 4 is the same, and at the same time, the two angle limit rods 532 are taken out from the angle limiting hole 531. At this time, when the adjusting rod 4 is rotated, the two ends of the limit plate 41 in the length direction will not interfere with the semicircular groove 52.

[0038] Example 6 Based on the first embodiment, Figure 1 、 Figures 3 to 7 、 Figure 9 As shown, the welding gun 6 is provided with a connecting rod 63 at the end away from the gun head, and the connecting rod 63 is movably arranged in the semicircular groove 52 at the end away from the welding gun 6. The connecting rod 63 is provided with an arc-shaped opening groove 61 at the end away from the welding gun 6, and the inner peripheral wall of the arc opening of the arc-shaped opening groove 61 is in contact with the outer peripheral wall of the circular ring 53; the connecting rod 63 is an externally threaded rod structure near the end of the welding gun 6, and the connecting rod 63 is threadedly connected to the welding gun 6 at the end near the welding gun 6, and is rotatably connected to the arc-shaped opening groove 61 at the end away from the welding gun 6; when the welding gun 6 is rotated to adjust its position (that is, the welding gun 6 is rotated to adjust its position with the axis of the adjusting rod 4 as the axis), the arc-shaped opening groove 61 slides synchronously on the outer peripheral wall of the circular ring 53, which is conducive to maintaining the stable position of the welding gun 6.

[0039] Since the connecting rod 63 is threadedly connected to the welding gun 6 at the end thereof near the welding gun 6, the connecting rod 63 is movable through the welding gun 6 at the end thereof near the welding gun 6, so that when the adjusting rod 4 is moved along the length direction of the axial center line of the driven bevel gear 33 on the adjusting slide 2, the connecting rod 63 can be rotated at the same time, thereby achieving the effect of adjusting the distance between the welding gun 6 and the fixing seat 1 according to the requirements of the welding position (the connecting rod 63 at the end thereof near the welding gun 6 is an externally threaded rod structure, and the external threads of the connecting rod 63 at the end thereof near the welding gun 6 are connected to a plurality of rotating nuts, which is conducive to fixing the position of the welding gun 6 on the connecting rod 63 at the end thereof near the welding gun 6).

[0040] Stoppers 521 are provided at both ends of the arc-shaped opening of the semicircular groove 52 , which are helpful in keeping the ring 53 located in the semicircular groove 52 .
