[0018] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0019] like Figures 1-5 As shown in the figure, this utility model provides a welding fixture for a hybrid cavity sub-assembly robot, including a fixture base plate 1. A flipping power device 2 and a clamping unit 3 connected to the flipping power device 2 are mounted on the fixture base plate 1. The clamping unit 3 is used to simultaneously clamp or simultaneously release hybrid cavity sub-assembly workpiece 4 and hybrid cavity sub-assembly workpiece 5. The flipping power device 2 can provide a driving force to the hybrid cavity sub-assembly workpiece 4 and hybrid cavity sub-assembly workpiece 5 clamped by the clamping unit 3 to rotate around their bodies. The fixture base plate 1 is set on a welding platform, which is part of the robot.

[0020] The clamping unit 3 can simultaneously clamp or release the first mixing chamber subassembly workpiece 4 and the second mixing chamber subassembly workpiece 5. After being clamped by the clamping unit 3, the first mixing chamber subassembly workpiece 4 and the second mixing chamber subassembly workpiece 5 can be rotated by the flipping power device 2.

[0021] It should be noted that this can be referred to Figure 2A weld 6 is provided between the first part of the mixing chamber subassembly 4 and the second part of the mixing chamber subassembly 5. The weld 6 includes a first section 601, a second section 602, and a third section 603 arranged sequentially and in a closed distribution.

[0022] The first segment 601, the second segment 602, and the third segment 603 have a lateral deviation. In order to complete the weld 6, a first support frame 7 and a second support frame 8 need to be set on the fixture base plate 1 to support the first mixing chamber sub-assembly workpiece 4 and the second mixing chamber sub-assembly workpiece 5. The first support frame 7 is rotatably engaged with the first mixing chamber sub-assembly workpiece 4, and the second support frame 8 is rotatably engaged with the second mixing chamber sub-assembly workpiece 5.

[0023] Specifically, an end plate is provided at the mixing chamber sub-assembly workpiece 4, the first support frame 7 includes two mounting plates that fit together, the two mounting plates surround a storage groove that rotates and engages with the end plate, and the second support frame 8 rests on the end face of the mixing chamber sub-assembly workpiece 5 on the side away from the end plate.

[0024] It should be noted that the fixture base plate 1 is provided with a transverse moving unit 9 connected to the first support frame 7 and the second support frame 8. The transverse moving unit 9 is used to drive the first support frame 7 and the second support frame 8 to move left and right. The stroke of the transverse moving unit 9 is greater than the maximum transverse distance of the first segment 601, the second segment 602 and the third segment 603 in the weld 6.

[0025] A welding torch is provided at the base plate 1 of the fixture for welding the mixing chamber sub-assembly workpiece 4 and the mixing chamber sub-assembly workpiece 2 5. The mixing chamber sub-assembly workpiece 4 and the mixing chamber sub-assembly workpiece 2 5 are stored on the first support frame 7 and the second support frame 8. The lateral movement unit 9 can adjust the left and right positions of the mixing chamber sub-assembly workpiece 4 and the mixing chamber sub-assembly workpiece 2 5. With the help of the flipping power device 2, which can drive the mixing chamber sub-assembly workpiece 4 and the mixing chamber sub-assembly workpiece 2 5 to rotate around, the area where the entire weld seam 6 is located can be aligned with the welding torch, thereby completing the welding work of the weld seam 6 with the curved distribution on the surface of the mixing chamber sub-assembly workpiece 4 and the mixing chamber sub-assembly workpiece 2 5.

[0026] For details, please refer to Figure 1 The lateral movement unit 9 includes at least two nuts 901, a lead screw 902 connected to the nuts 901 by threads, a power housing 903 that is rotatably engaged with the lead screw 902 and slidably engaged with the nuts 901, and a power motor 904 connected to the lead screw 902 and mounted on the fixture base plate 1. One nut 901 is mounted on the bottom of the first support frame 7, and the other nut 901 is mounted on the lower side of the second support frame 8. The fixture base plate 1 is provided with a sliding groove that is slidably engaged with the first support frame 7, and a wear-resistant plate 905 is provided in the sliding groove that abuts against the first support frame 7.

[0027] To ensure that components such as the clamping unit 3 can always be pushed by the flipping power device 2 as the first support frame 7 moves, a structural guarantee can be provided, as detailed in the following reference. Figure 5 A corresponding insert rod is provided at the rotary motor 302 in the clamping unit 3. The flipping power device 2 is provided with a drive motor for driving and a connecting sleeve connected to the output shaft of the drive motor and slidingly engaged with the insert rod. The insert rod can be a square rod. In this way, when the insert rod and the rotary motor 302 move, the rotating connecting sleeve can still drive the insert rod and the rotary motor 302 to rotate, thereby driving the mixing chamber sub-assembly workpiece 1 4 and the mixing chamber sub-assembly workpiece 2 5 to rotate.

[0028] For details, please refer to Figure 3-5 The clamping unit 3 includes a rotating shaft 301 that coincides with the center line of the workpiece 4 of the mixing chamber sub-assembly, a rotary motor 302 connected to the rotating shaft 301, a movable seat 303 that is threadedly connected to the threaded part on the rotating shaft 301, a first inclined plate 304 rotatably mounted on the movable seat 303, a second inclined plate 305 rotatably engaged with the first inclined plate 304, a support block 306 mounted on one end of the second inclined plate 305, and a fixed seat 307 that is aligned with the movable seat 303 and movably engaged with the second inclined plate 305.

[0029] The rotary motor 302 can drive the rotary shaft 301 to rotate. Through the threaded connection of the rotary shaft 301 and the movable seat 303, when the rotary shaft 301 rotates, the movable seat 303 will move left and right. During the movement of the movable seat 303, the first inclined plate 304 pushes and pulls the second inclined plate 305, thereby causing the support block 306 on the second inclined plate 305 to abut against the inner wall of the mixing chamber sub-assembly workpiece 4 or to separate the support block 306 from the mixing chamber sub-assembly workpiece 4, thereby completing the clamping and loosening effect of the mixing chamber sub-assembly workpiece 4 and the mixing chamber sub-assembly workpiece 5.

[0030] To prevent the movable seat 303 from rotating together with the rotating shaft 301, a positioning rod 308 is provided in the clamping unit 3, which is distributed parallel to the rotating shaft 301. The positioning rod 308 is set on the motor bracket for mounting the rotary motor 302, and the positioning rod 308 slides with the two movable seats 303.

[0031] In summary, this utility model provides a welding fixture for a hybrid cavity sub-assembly robot. A welding torch for welding hybrid cavity sub-assembly workpiece 4 and hybrid cavity sub-assembly workpiece 2 5 is provided on the fixture base plate 1. Hybrid cavity sub-assembly workpiece 4 and hybrid cavity sub-assembly workpiece 2 5 are stored on a first support frame 7 and a second support frame 8. A lateral movement unit 9 can adjust the left and right positions of hybrid cavity sub-assembly workpiece 4 and hybrid cavity sub-assembly workpiece 2 5. Combined with a flipping power device 2 that can drive hybrid cavity sub-assembly workpiece 4 and hybrid cavity sub-assembly workpiece 2 5 to rotate around their bodies, the area containing the entire weld seam 6 can be aligned with the welding torch, thereby completing the welding work of the weld seam 6 with its curved surface distribution on hybrid cavity sub-assembly workpiece 4 and hybrid cavity sub-assembly workpiece 2 5.

[0032] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
