[0021] An embodiment of the present application discloses a cross-shaped welding manipulator. Referring to Figure 1 , Figure 2 and Figure 3 , the cross-shaped welding manipulator includes a fixed seat 1, an X-axis servo slide rail 2, a Y-axis servo slide rail 3 and a welding gun head 4. The X-axis servo slide rail 2 is connected to the fixed seat 1, and the X-axis servo slide rail 2 is arranged in a direction perpendicular to the fixed seat 1. The Y-axis servo slide rail 3 is connected to the movable seat of the X-axis servo slide rail 2, and the Y-axis servo slide rail 3 is arranged perpendicular to the X-axis servo slide rail 2. An installation frame 31 is connected to the movable seat of the Y-axis servo slide rail 3. An installation ring 41 is connected to the welding gun head 4. The installation ring 41 is sleeved outside the welding gun head 4. The installation ring 41 is rotatably connected to the installation frame 31. An adjusting plate 5 is connected to the installation frame 31. The adjusting plate 5 is arranged in a semi-circular arc shape. The center of the adjusting plate 5 is concentric with the center of rotation of the installation ring 41. A locking component 6 for cooperating with the adjusting plate 5 to lock the welding gun head 4 is provided on the installation ring 41.

[0022] A fixed shaft 411 is connected to the installation ring 41. The fixed shaft 411 is arranged along the radial direction of the installation ring 41. One fixed shaft 411 is provided on each of the opposite sides of the installation ring 41. A connection hole for the fixed shaft 411 to penetrate and rotate is provided on the installation frame 31. The rotational connection of the installation ring 41 is realized by setting the fixed shaft 411 and providing a connection hole on the installation frame 31.

[0023] The locking assembly 6 includes a fixed cylinder 61, a cylinder cover 62, a pull rod 63, a slider 64, a spring 65, a pull block 66 and a locking post 67. The fixed cylinder 61 is connected to the mounting ring 41. The fixed cylinder 61 is arranged radially along the mounting ring 41, and one is provided on each of the opposite sides of the mounting ring 41. A chute 51 for the fixed cylinder 61 to slide is formed on the adjusting plate 5. The cylinder cover 62 is connected to the mouth of the fixed cylinder 61. The pull rod 63 passes through the cylinder cover 62 and is arranged inside the fixed cylinder 61. The axis of the pull rod 63 is collinear with the axis of the fixed cylinder 61. The slider 64 is connected to the end of the pull rod 63 inside the fixed cylinder 61. The side wall of the slider 64 is slidably attached to the inner wall of the fixed cylinder 61. The spring 65 is sleeved on the rod body of the pull rod 63 inside the fixed cylinder 61. One end of the spring 65 abuts against the slider 64, and the other end abuts against the cylinder cover 62. The pull block 66 is connected to the end of the pull rod 63 that does not penetrate into the fixed cylinder 61. The locking post 67 is connected to the pull block 66. The locking post 67 is arranged in a direction perpendicular to the pull block 66. A locking hole 52 for the locking post 67 to insert is formed on the adjusting plate 5, and a plurality of locking holes 52 are uniformly arranged along the length direction of the adjusting plate 5.

[0024] When locking, the locking post 67 is inserted into the locking hole 52 of the adjusting plate 5, so that the welding gun head 4 cannot rotate. When adjusting, the pull block 66 is pulled outwards, so that the locking post 67 is disengaged from the locking hole 52. After the welding gun head 4 is adjusted to the appropriate position, the pull block 66 is released, and the spring 65 is used to push the slider 64 to drive the pull block 66 through the pull rod 63, so that the locking post on the pull block 66 is inserted into the locking hole 52 of the adjusting plate 5.

[0025] The end of the locking post inserted into the locking hole 52 is rounded, so that it is convenient for the locking post to be inserted into the locking hole 52, which is beneficial to improving the locking efficiency.

[0026] A handle 661 is connected to the pull block 66. The handle 661 is located on the surface of the pull block 66 facing away from the adjusting plate 5. By providing the handle 661, it is convenient for the operator to grasp the pull block 66.

[0027] The mounting ring 41 is made of heat-insulating material. The heat of the welding gun head 4 is isolated through the mounting ring 41 to avoid scalding the operator.

[0028] The implementation principle of a cross-shaped welding manipulator in an embodiment of this application is as follows: When manual welding is required, the welding torch 4 is adjusted to the vicinity of the welding point through the X-axis servo slide guide 2 and the Y-axis servo slide guide 3. Then, the pull block 66 is pulled outwards, so that the locking column 67 disengages from the locking hole 52, and the user can manually rotate the welding torch 4 for manual welding operation or adjust the angle of the welding torch 4. When the appropriate angle is reached, the pull block 66 is released, and the spring 65 is used to push the slider 64 to drive the pull block 66 through the pull rod 63, so that the locking part on the pull block 66 is inserted into the locking hole 52 of the adjusting plate 5. When the welding point is flat and welding can be performed mechanically, the welding torch 4 is locked through the locking assembly 6, and welding can be completed through the X-axis servo slide guide 2 and the Y-axis servo slide guide 3.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
