[0057] In one embodiment, see Figure 3Each circular support base 16 has a circular clamping groove for clamping the stator core 201. A circular guide wheel 161 is rotatably mounted on the bottom of each circular support base 16. A plurality of circular guide holes 151 are arranged in a circular array along the center of the circular rotating disk 15.

After the dome assembly is completed, the stator body 20 can be removed by the line-moving component 8. Subsequently, the assembly rotating component 17 drives the assembly rotating disk 15 to rotate in the opposite direction.

This structure, through the alignment and fit between the welding guide pillars and the fixture positioning holes, enables the transfer fixture 24 and the welding base 41 to be aligned and installed, and also prevents the transfer fixture 24 from rotating relative to the welding base 41. The number of welding guide pillars can be multiple, the same as the number of fixture positioning holes. Multiple welding guide pillars can be inserted into multiple fixture positioning holes respectively, improving the alignment accuracy between the transfer fixture 24 and the welding base 41.

The unloading lifting member 53 is mounted on the unloading fixture bracket 51 and connected to the unloading ejector seat 52. The unloading lifting member 53 can be a cylinder, electric cylinder, etc. In this structure, the unloading ejector seat 52 is driven to rise by the unloading lifting member 53, allowing the unloading ejector seat 52 to extend into the mounting hole 241 and eject the stator body 20 from the transfer fixture 24, so that subsequent operations can be performed on the welded stator body 20.

[0069] Optionally, a discharge sensing element is installed on the discharge top seat 52, and a discharge sensor is installed on the discharge fixture bracket 51. This structure, through the sensing interaction between the discharge sensing element and the discharge sensor, can limit the lifting stroke of the discharge top seat 52. The number of discharge sensors can be two, with the discharge sensing element positioned between the two sensors.

[0070] In one embodiment, see Figure 10As a specific embodiment of the welding measuring device provided in this application, the welding measuring device further includes a detection and transfer assembly 9. This assembly 9 includes a first gripper 91 for gripping the stator body 20 ejected from the ejector seat 52, a gripping rotating component 92 for driving the first gripper 91 to rotate, a first support frame 93 and a second support frame 94 respectively mounted on the frame 10, a second gripper 95 for gripping the stator body 20 on the first gripper 91, and a gripping drive unit 96 for driving the second gripper 95 to reciprocate between the first gripper 91 and the outer diameter detection assembly 6. The gripping rotating component 92 is mounted on the first support frame 93 and connected to the first gripper 91, and the gripping drive unit 96 is mounted on the second support frame 94 and connected to the second gripper 95. Both the first gripper 91 and the second gripper 95 can be finger cylinders; the gripping rotating component 92 can be a rotary motor. This structure allows the first gripper 91 to grip the stator body 20 ejected from the discharge ejector seat 52; the clamping rotating member 92 can drive the first gripper 91 to rotate, thereby achieving the flipping of the stator body 20, specifically flipping the stator body 20 by 180 degrees, so that the wire harness 202 at the top of the stator body 20 can be flipped to the bottom position, realizing the position adjustment of the wire harness 202; the second gripper 95 can grip the stator body 20 gripped by the first gripper 91, and the clamping driving unit 96 can transfer the stator body 20 to the outer diameter detection component 6 or the inner diameter detection component 7.

[0071] Optionally, the clamping drive unit 96 may include at least one of the following: a clamping lifting module for driving the second gripper 95 to rise and fall, a clamping lateral movement module for driving the second gripper 95 to move laterally, and a clamping longitudinal movement module for driving the second gripper 95 to move longitudinally.

[0072] In one embodiment, see Figure 11As a specific embodiment of the welding measurement equipment provided in this application, the outer diameter detection assembly 6 includes an outer diameter detection bracket 61 mounted on the frame 10, an outer diameter gripper 62 for clamping the stator body 20, an outer diameter rotating seat 63 supporting the outer diameter gripper 62, an outer diameter rotating component 64 for driving the outer diameter rotating seat 63 to rotate, two outer diameter detection heads 65 for detecting the outer diameter of the stator body 20, and two outer diameter moving components 66 for respectively driving the two outer diameter detection heads 65 closer to or further away from the stator body 20. The two outer diameter detection heads 65 are located on both sides of the outer diameter gripper 62, the outer diameter rotating component 64 is mounted on the outer diameter detection bracket 61 and connected to the outer diameter rotating seat 63, and the two outer diameter moving components 66 are respectively mounted on the outer diameter detection bracket 61 and respectively connected to the two outer diameter detection heads 65. The outer diameter gripper 62 can be a finger cylinder or a three-jaw cylinder, etc. This structure allows the stator body 20 to be transferred onto the outer diameter rotating seat 63 via the second gripper 95 and the clamping drive unit 96, and the stator body 20 to be clamped and fixed via the outer diameter gripper 62. Two outer diameter moving parts 66 drive two outer diameter detection heads 65 to approach the stator body 20 to detect its outer diameter. The outer diameter rotating part 64 drives the outer diameter rotating seat 63 to rotate, thus allowing for repeated rotational measurements of the stator body 20's outer diameter. The final outer diameter dimension of the stator body 20 is obtained by averaging the multiple sets of measured outer diameter data.

[0073] In one embodiment, see Figure 11 Multiple outer diameter support guide posts 631 are installed on the outer diameter rotating seat 63. The multiple outer diameter support guide posts 631 can support the bottom of the stator body 20 to avoid the wire harness 202 on the stator body 20.

[0074] In one embodiment, see Figure 11 Each outer diameter detection head 65 includes an outer diameter detection sliding seat 651 slidably mounted on an outer diameter detection bracket 61, an outer diameter detector 652 mounted on the outer diameter detection sliding seat 651, and an outer diameter detection push seat 653 slidably mounted on the outer diameter detection sliding seat 651. The end of the outer diameter detector 652 abuts against the outer diameter detection push seat 653. The outer diameter detector 652 can be any commonly used detector on the market, and will not be described in detail here. In this structure, the outer diameter detection head 65 is driven closer to the stator body 20 by the outer diameter moving member 66. When the outer diameter detection push seat 653 abuts against the outer circumferential surface of the stator body 20, it pushes against the outer diameter detector 652. When the outer diameter detector 652 is pushed by the outer diameter detection push seat 653, it generates a compression. The outer diameter of the stator body 20 is detected by the compression amount detected by the outer diameter detector 652 when the outer diameter detection sliding seat 651 moves a target distance.

[0075] In one embodiment, see Figure 12 As a specific embodiment of the welding measurement equipment provided in this application, the inner diameter detection assembly 7 includes an inner diameter gripper 71 for clamping the stator body 20, an inner diameter rotating seat 72 for supporting the inner diameter gripper 71, an inner diameter rotating member 73 for driving the inner diameter rotating seat 72 to rotate, an inner diameter sliding seat 74 for supporting the inner diameter rotating member 73, an inner diameter driving member 75 for driving the inner diameter sliding seat 74 to reciprocate, an inner diameter detection head 76 for detecting the inner diameter of the stator body 20, and an inner diameter lifting member 77 for driving the inner diameter detection head 76 to move in and out of the stator body 20; the inner diameter driving member 75 is mounted on the frame 10 and connected to the inner diameter sliding seat 74, and the inner diameter lifting member 77 is mounted on the frame 10 and connected to the inner diameter detection head 76. The inner diameter gripper 71 can be a finger cylinder or a three-jaw cylinder, etc.; the inner diameter rotating component 73 can be a rotary motor; the inner diameter driving component 75 can be a cylinder / electric cylinder / screw drive mechanism, a linear motor, etc.; the inner diameter detection head 76 is a commonly used detector on the market, which will not be described in detail here; the inner diameter lifting component 77 can be a cylinder / electric cylinder / screw drive mechanism, a linear motor, etc. In this structure, the stator body 20 transferred by the second gripper 95 and the clamping drive unit 96 can be supported by the inner diameter rotating seat 72, and the stator body 20 can be clamped and fixed by the inner diameter gripper 71. The inner diameter lifting component 77 can drive the inner diameter detection head 76 to extend into the stator body 20, and the inner diameter of the stator body 20 can be detected by the inner diameter detection head 76. The inner diameter rotating component 73 drives the inner diameter rotating seat 72 to rotate, thus enabling repeated detection of the inner diameter of the stator body 20. The average value of the multiple inner diameter values ​​obtained is used to obtain the final inner diameter dimension of the stator body 20. After the detection is completed, the stator body 20 can be removed by the inner diameter driving component 75, making it easy for manual or robotic arms to pick up the stator body 20.

[0076] In one embodiment, see Figure 12 Multiple inner diameter support guides 721 are installed on the inner diameter rotating seat 72. The multiple inner diameter support guides 721 can support the bottom of the stator body 20 so as to avoid the wire harness 202 on the stator body 20.

[0077] In one embodiment, see Figure 12 The inner diameter rotating seat 72 is also equipped with multiple inner diameter positioning seats 722. Each inner diameter positioning seat 722 has an inner diameter positioning rib protruding. The multiple inner diameter positioning ribs can be inserted into the stator groove 203 of the stator body 20 to achieve positioning of the stator body 20 and prevent the stator body 20 from rotating.
