[0035] Below is the accompanying drawings Figures 1 to 4 The technical solution of the utility model is further illustrated through specific implementation methods.

[0036] like Figure 1-4As shown, a welding gun adjustment mechanism includes an X-axis transmission assembly 1, a Y-axis transmission assembly 2, a Z-axis transmission assembly 3, a reciprocating movement assembly 4, a rotating assembly 5, a swinging assembly 6 and a welding gun;

[0037] The Y-axis transmission assembly 2 is installed on the X-axis transmission assembly 1, and the X-axis transmission assembly 1 is used to drive the Y-axis transmission assembly 2 to move along the X-axis direction;

[0038] The Z-axis transmission assembly 3 is installed on the Y-axis transmission assembly 2, and the Y-axis transmission assembly 2 is used to drive the Z-axis transmission assembly 3 to move along the Y-axis direction;

[0039] The reciprocating assembly 4 is installed on the Z-axis transmission assembly 3, and the Z-axis transmission assembly 3 is used to drive the reciprocating assembly 4 to move along the Z-axis direction;

[0040] The rotating assembly 5 is installed on the reciprocating assembly 4, and the reciprocating assembly 4 is used to drive the rotating assembly 5 to reciprocate;

[0041] The swing assembly 6 is mounted on the rotating assembly 5, and the rotating assembly 5 is used to drive the swing assembly 6 to rotate around the rotating axis of the rotating assembly 5;

[0042] The welding gun is mounted on the swing assembly 6 , and the swing assembly 6 is used to drive the welding gun to swing so as to adjust the angle between the welding gun and the rotating assembly 5 .

[0043] It can be understood that the position of the welding gun can be adjusted along the X-axis, Y-axis and Z-axis through the set X-axis transmission assembly 1, Y-axis transmission assembly 2, and Z-axis transmission assembly 3, and the direction of the welding gun can be adjusted through the rotating assembly 5 and the swinging assembly 6, and the welding gun can be driven to move back and forth by the reciprocating moving assembly 4 to perform welding operations to meet the welding requirements in different directions. It is worth noting that this equipment is used for gas-electric vertical welding and gas-electric horizontal welding equipment, and can also be used for other welding equipment.

[0044] like Figure 2 As shown, the X-axis transmission assembly 1 includes a fixed base 11, a groove is formed at the top of the fixed base 11, a first threaded rod 12 is rotatably connected between the inner side walls of the groove, and a movable base 13 is threadedly connected to the outer side of the first threaded rod 12. The top of the movable base 13 passes through the groove and extends to the outside of the fixed base 11 to be connected to the Y-axis transmission assembly 2;

[0045] A support plate 16 is installed at the top of the fixed seat 11, and the support plate 16 slides through the movable seat 13. A first driving member 15 is installed at the top of the support plate 16. The driving end of the first driving member 15 passes through the support plate 16 and extends into the groove and is coaxially connected to a first bevel gear 151. The first bevel gear 151 is meshed with a second bevel gear 121, and the second bevel gear 121 is fixedly sleeved on the outside of the first threaded rod 12.

[0046] Specifically, the first driving member 15 drives the first bevel gear 151 to rotate, the first bevel gear 151 drives the meshing second bevel gear 121 to rotate, and the second bevel gear 121 drives the first threaded rod 12 to rotate. During the rotation of the first threaded rod 12, the movable seat 13 moves along the support plate 16, thereby driving the Y-axis transmission assembly 2 to move along the X-axis direction through the movable seat 13.

[0047] like Figure 1-2 As shown, a guide rail pair 14 is installed on the side wall of the movable seat 13, and the guide rail pair 14 is installed on the inner side wall of the groove.

[0048] Specifically, the guide rail pair 14 can enable the movable seat 13 to move stably and smoothly.

[0049] like Figure 2-3 As shown, the Y-axis transmission assembly 2 includes a fixed sleeve 21 and a second driving member 24. The fixed sleeve 21 is fixedly inserted into the interior of the movable seat 13. An internal gear sleeve 22 is fixed in the fixed sleeve 21, and an external gear sleeve 23 is meshedly connected to the internal gear sleeve 22.

[0050] The driving end of the second driving member 24 passes through the fixed sleeve 21 and extends to the inside of one end of the external gear sleeve 23. The driving end of the second driving member 24 is threadedly connected to the external gear sleeve 23. The other end of the external gear sleeve 23 passes through the fixed sleeve 21 and extends to the outside to be connected to a first mounting seat 25. The Z-axis transmission assembly 3 is fixedly mounted on the first mounting seat 25.

[0051] Specifically, since the outer gear sleeve 23 is meshed with the inner gear sleeve 22, the second driving member 24 can drive the outer gear sleeve 23 to move along the axis of the inner gear sleeve 22 when the driving end of the second driving member 24 is threadedly connected to the outer gear sleeve 23. During the movement of the outer gear sleeve 23, the first mounting seat 25 is driven to move, thereby driving the Z-axis transmission assembly 3 to move along the Y-axis direction.

[0052] like Figure 3 As shown, the structure of the Z-axis transmission assembly 3 is consistent with the structure of the Y-axis transmission assembly 2.

[0053] Specifically, the structure of the Z-axis transmission assembly 3 is consistent with that of the Y-axis transmission assembly 2 , which can reduce the types of parts required to manufacture the device, thereby reducing the manufacturing difficulty of the device.

[0054] like Figure 1 As shown, the reciprocating component 4 is a reciprocating linear module.

[0055] Specifically, the reciprocating linear module can achieve precise position control and can operate smoothly, thereby making the position adjustment of the welding gun more accurate and driving the welding gun to move back and forth to perform welding.

[0056] like Figure 4 As shown, the rotating assembly 5 includes a second mounting seat 51, which is mounted on the driving end of the reciprocating assembly 4, and a worm 52 is rotatably mounted in the second mounting seat 51. A third driving member 56 is provided on the outside of the second mounting seat 51, and the driving end of the third driving member 56 passes through the second mounting seat 51 and is coaxially connected to the worm 52. A worm wheel 53 is meshed with one side of the worm 52, and a rotating shaft 54 ​​is coaxially mounted on the worm wheel 53. The rotating shaft 54 ​​is rotatably mounted in the second mounting seat 51, and one end of the rotating shaft 54 ​​passes through the second mounting seat 51 and extends to the outside to be connected to the third mounting seat 55. The swinging assembly 6 is mounted on the side of the third mounting seat 55 away from the second mounting seat 51.

[0057] Specifically, the worm 52 is driven to rotate by the third driving member 56, and the rotation of the worm 52 drives the worm wheel 53 to rotate, the worm wheel 53 drives the coaxially connected rotating shaft 54 ​​to rotate, the rotating shaft 54 ​​drives the third mounting seat 55 to rotate, and the third mounting seat 55 drives the swing assembly 6 to rotate, thereby driving the welding gun installed on the swing assembly 6 to rotate.

[0058] like Figure 4 As shown, the swing assembly 6 includes a fourth mounting seat 61 and a second threaded rod 63. One end of the fourth mounting seat 61 is hinged to the side of the third mounting seat 55 away from the second mounting seat 51. The welding gun is detachably mounted on the other end of the fourth mounting seat 61. A through hole 62 is formed in the side wall of the fourth mounting seat 61. The diameter of the through hole 62 is larger than the diameter of the second threaded rod 63.

[0059] The second threaded rod 63 is movably arranged to pass through the through hole 62. One end of the second threaded rod 63 is coaxially connected to the rotating shaft 54. The other end of the second threaded rod 63 is threadedly sleeved with a pressure cap 64. One end of the pressure cap 64 presses against a side of the fourth mounting seat 61 away from the third mounting seat 55.

[0060] A spring 65 is connected between the fourth mounting seat 61 and the third mounting seat 55 , and the spring 65 is sleeved on the outside of the second threaded rod 63 .

[0061] Specifically, the pressure cap 64 is rotated and moves along the axis of the second threaded rod 63. When the pressure cap 64 gradually approaches the third mounting seat 55, the pressure cap 64 drives the fourth mounting seat 61 to move, so that the fourth mounting seat 61 rotates in the direction of the third mounting seat 55, thereby reducing the angle between the welding gun and the third mounting seat 55. At this time, the spring 65 is in a compressed state. When the pressure cap 64 gradually moves away from the third mounting seat 55, the compressed spring 65 gradually returns to its original state. The spring 65 pushes the fourth mounting seat 61 to move, so that the fourth mounting seat 61 rotates in the direction away from the third mounting seat 55, thereby increasing the angle between the welding gun and the third mounting seat 55.

[0062] like Figure 1-4 As shown, the first driving member 15, the second driving member 24 and the third driving member 56 are manual levers or driving motors.

[0063] Specifically, when the first drive member 15, the second drive member 24 and the third drive member 56 use manual rods, their purchase price is cheap, which can reduce the manufacturing cost of the device. When the first drive member 15, the second drive member 24 and the third drive member 56 use drive motors, workers can remotely adjust the position of the welding gun quickly through the drive motor, thereby improving the degree of automation of the device and facilitating the use of the device in harsh welding environments.

[0064] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
