[0019] Please refer to Figures 1 to 4 , wherein Figure 1 is the structural schematic diagram of the welding arm with adjustable angle and height of the present utility model Figure 2 is of the present utility model Figure 1 The enlarged view of position A in Figure 3 is the structural schematic diagram of another direction of the welding arm with adjustable angle and height of the present utility model Figure 4 is the structural schematic diagram of the moving frame and the support frame of the welding arm with adjustable angle and height of the present utility model

[0020] The present utility model provides a welding arm with adjustable angle and height, including a base 101, a welding joint 113 and an adjusting mechanism. The adjusting mechanism includes a rotating table 117, a plurality of support frames 112, a driving assembly, a fixed frame 107, a servo motor 102, a lead screw 109, a moving block 110 and a moving frame 111. The driving assembly includes a mounting frame 103, a power kit and a driven gear 106. The power kit includes a rotating motor 108, a rotating shaft 104 and a driving gear 105. Through the foregoing solution, the problem in the prior art that the welding joint 113 of the device cannot be adjusted and the welding joint 113 can only weld at fixed positions, reducing the applicability of the device, is solved

[0021] In this embodiment, the welding joint 113 is located above the base 101. The rotating table 117 is fixedly connected to the base 101. The driving assembly is disposed on the rotating table 117 and the base 101. The fixing frame 107 is fixedly connected to the rotating table 117. The servo motor 102 is fixedly connected to the fixing frame 107. The lead screw 109 is fixedly connected to the output end of the servo motor 102 and is located within the fixing frame 107. The moving block 110 is threadedly connected to the lead screw 109. One end of the moving frame 111 is fixedly connected to the moving block 110. The welding joint 113 is fixedly connected to the other end of the moving frame 111. When adjusting the position of the welding joint 113, start the driving assembly. The driving assembly drives the rotating table 117 and the fixing frame 107 to rotate. The moving frame 111 and the welding joint 113 rotate about the rotating table 117 as the central axis, thereby adjusting the angle of the welding joint 113. Start the servo motor 102. The servo motor 102 drives the lead screw 109 to rotate. The moving block 110 and the moving frame 111 move up and down as the lead screw 109 rotates, thereby changing the height of the welding joint 113. The welding joint 113 can be adjusted to an appropriate position, increasing the applicability of the device.

[0022] Further, the mounting frame 103 is fixedly connected to the base 101. The power kit is disposed on the mounting frame 103. The driven gear 106 is fixedly connected to the rotating table 117.

[0023] Further, the rotating motor 108 is fixedly connected to the mounting frame 103. The rotating shaft 104 is fixedly connected to the output end of the rotating motor 108 and extends into the mounting frame 103. The driving gear 105 is fixedly connected to the rotating shaft 104. The driving gear 105 is meshed with the driven gear 106.

[0024] In this embodiment, when adjusting the position of the welding joint 113, start the rotary motor 108. The rotary motor 108 drives the rotating shaft 104 to rotate. The rotating shaft 104 drives the driving gear 105 to rotate. The driven gear 106 and the driving gear 105 are connected by meshing. The driving gear 105 drives the driven gear 106 and the rotating table 117 to rotate. The rotating table 117 and the fixing frame 107 rotate synchronously. The moving frame 111 and the welding joint 113 rotate around the rotating table 117 as the central axis, thereby adjusting the angle of the welding joint 113. Start the servo motor 102. The servo motor 102 drives the lead screw 109 to rotate. The moving block 110 and the moving frame 111 move up and down as the lead screw 109 rotates, thereby changing the height of the welding joint 113. The welding joint 113 can be adjusted to an appropriate position, increasing the applicability of the device.

[0025] Further, a plurality of the support frames 112 are fixedly connected to the moving frame 111 and are located inside the moving frame 111.

[0026] In this embodiment, to reduce the stress on the lead screw 109, the moving frame 111 adopts a hollow design to reduce the weight. A plurality of the support frames 112 reinforce the moving frame 111, ensuring that the structural strength of the moving frame 111 is increased as much as possible while the weight of the moving frame 111 is relatively light, increasing the structural rationality of the device.

[0027] Further, two of the support mechanisms are provided on the moving frame 111 and the fixing frame 107.

[0028] Further, one end of the support rod 114 is fixedly connected to the moving frame 111. The mounting seat 115 is fixedly connected to the other end of the support rod 114. The roller 116 is rotatably connected to the mounting seat 115 and is located inside the mounting seat 115. The roller 116 is slidably connected to the fixing frame 107.

[0029] In this embodiment, when the moving frame 111 and the welding joint 113 move up and down, due to the relatively large moment of the welding joint 113 on the moving block 110 and the lead screw 109, the moving frame 111 and the moving block 110 are subjected to strong pressure. When the moving frame 111 moves up and down, the two rollers 116 slide on both sides of the fixing frame 107. The two rollers 116 and the two support rods 114 provide an upward support force for the moving frame 111, ensuring that the moving frame 111 will not break or be misaligned during operation, increasing the stability of the device.

[0030] When adjusting the position of the welding joint 113 using the present utility model, start the rotary motor 108. The rotary motor 108 drives the rotating shaft 104 to rotate. The rotating shaft 104 drives the driving gear 105 to rotate. The driven gear 106 and the driving gear 105 are connected by meshing. The driving gear 105 drives the driven gear 106 and the rotating table 117 to rotate. The rotating table 117 and the fixed frame 107 rotate synchronously. The moving frame 111 and the welding joint 113 rotate around the rotating table 117 as the central axis, thereby adjusting the angle of the welding joint 113. Start the servo motor 102. The servo motor 102 drives the lead screw 109 to rotate. The moving block 110 and the moving frame 111 move up and down as the lead screw 109 rotates, thereby changing the height of the welding joint 113. The welding joint 113 can be adjusted to an appropriate position, increasing the applicability of the device.
