The terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following describes the implementation method of the present utility model based on its overall structure.

[0030] Reference Figure 1 As shown, an embodiment of the present application provides a welding detection device, comprising:

[0031] A moving member 1, wherein the moving member 1 has a first end 11 and a second end 12;

[0032] The first end 11 of the moving member 1 contacts the workpiece 2, and the second end 12 of the moving member 1 is arranged close to the detection end of the sensor 3;

[0033] A fixing part 4 is sleeved in the middle of the moving part 1, a through slot 41 is formed in the fixing part 4, and the moving part 1 reciprocates along the direction in which the through slot 41 extends;

[0034] An elastic member 5 is sleeved on the outer wall of the middle position of the moving member 1 , one end of the elastic member 5 is mounted on the outer wall of the moving member 1 , and the other end of the elastic member 5 is mounted on the inner wall of the fixed part 4 for resetting the moving member 1 .

[0035] according to Figure 1 After welding the nut on the workpiece 2, the technicians in this field need to continue welding the workpiece 2. In the present application, the workpiece 2 and the moving part 1 can be set to conflict with each other. Further, the relative position of the moving part 1 is detected by the sensor 3, and then the welding condition on the workpiece 2 can be indirectly detected.

[0036] Specifically, a first end 11 and a second end 12 may be provided on the moving member 1. In one embodiment, the first end 11 of the moving member 1 contacts the portion to be measured of the workpiece 2. The second end 12 of the moving member 1 is provided in a corresponding and close relationship with the sensor 3.

[0037] By means of the above structure, those skilled in the art can set that when there is no nut welded on the workpiece 2, when the first end 11 of the moving member 2 contacts the workpiece 2, the distance between the second end 12 of the moving member 2 and the sensor 3 is the first distance. When a nut is welded on the workpiece 2, when the first end 11 of the moving member 2 contacts the workpiece 2, the distance between the second end 12 of the moving member 2 and the sensor 3 is the second distance.

[0038] Furthermore, when the workpiece 2 is detected, if the sensor 3 detects and displays the second distance, it means that the nut welding on the workpiece 2 is completed and the next processing can be carried out. If the sensor 3 detects and displays the first distance, it means that the nut on the workpiece 2 is not welded, and the workpiece 2 can be moved and the nut welding can be carried out again.

[0039] It is understandable that in the above process, if there is no nut welded on the workpiece 2, the first end 11 of the moving member 1 directly contacts the outer wall of the workpiece 2. If a nut is welded on the workpiece 2, the first end 11 of the moving member 1 directly contacts the end side of the nut.

[0040] A fixing part 4 is sleeved at the middle position of the moving member 1, a through slot 41 is provided in the fixing part 4, and the moving member 1 reciprocates along the direction in which the through slot 41 extends. That is, those skilled in the art can arrange that the outer wall of the moving member is sleeved with the fixing part 4, and the fixing part 4 can constrain the relative position of the moving member 1.

[0041] In the actual process, the moving member 1 is inserted into the through slot 41 in the fixing portion 4. It can be understood that the moving member 1 reciprocates along the extending direction of the through slot 41.

[0042] An elastic member 5 is also arranged on the outer wall of the moving member 1. The elastic member 5 is arranged at the middle position of the outer wall of the moving member 1. One end of the elastic member 5 is mounted on the outer wall of the moving member 1, and the other end of the elastic member 5 is mounted on the inner wall of the fixing portion 4.

[0043] By means of the above structure, a nut is welded on the workpiece 2, and the first end 11 of the movable member 1 directly contacts the end side of the nut. The movable member 1 moves toward the location of the sensor 3, and the elastic member 5 is compressed. When the detection is completed, the elastic member 5 restores the deformation. Then the movable member 1 can be reset. In one embodiment, the elastic member 5 can be set as a spring.

[0044] In summary, those skilled in the art can set the moving part 1 and the sensor 3 to detect the welding condition of the nut on the workpiece 2.

[0045] In the above-mentioned embodiment, the first end 11 of the moving member 1 is provided to abut against the workpiece 2. In this embodiment, preferably, a stopper 111 is installed near the first end 11, and the workpiece 2 abuts against the stopper 111. Specifically, according to Figure 3 A stopper 111 is provided near the first end portion 11 , and the stopper 111 may be provided in the form of a circular plate or in a stepped shape.

[0046] In the above embodiment, if the stopper 111 is set as a circular plate, specifically, the inner wall of the stopper 111 is fixedly connected to the side wall of the first end 11. The stopper 111 contacts the side wall of the workpiece 2, thereby detecting the welding condition of the workpiece.

[0047] In addition, if the stopper 111 is set to be stepped, specifically, the stepped stopper 111 extends and protrudes in a direction away from the central axis of the moving member 1. It can be understood that in this embodiment, the stepped stopper 111 can be set to extend and close along the outer wall of the first end portion 11. Further, the stopper 111 contacts the workpiece 2 toward the side wall of the workpiece 2. Then, the welding condition of the workpiece can be detected.

[0048] In the above arrangement, a stopper 111 is provided near the first end 11, and the stopper 111 contacts the workpiece 2. Preferably, the workpiece 2 is provided with a detection hole 21, the first end 11 is provided with the detection hole 21, and the stopper 111 contacts the workpiece 2. Figure 3, the detection hole 21 opened on the workpiece can allow the first end 11 of the moving member 1 to pass through. In addition, the nut can be in contact with the stopper 111 on the first end 11 over a larger area, which can make the welding of the nut on the workpiece 2 more accurate. More preferably, the first end 11 is set to a truncated cone shape. In the process of passing through the detection hole 21, the truncated cone-shaped first end 11 can avoid the jamming caused by collision with the hole wall of the detection hole 21.

[0049] In the above structure, a stopper 111 is provided, through which the welding condition on the workpiece 2 can be detected. Preferably, the cross section of the stopper 111 is set to be circular, and a circular step portion 411 is provided at one end of the through slot 41 on the fixing part 4, and the step portion 411 is set to conflict with the stopper 111. That is, a position relative to the stopper 111 is set in the through slot 41, and the relative position of the moving part 1 can be positioned. At the same time, the conflict between the step portion 411 and the stopper 111 can limit the setting position of the stopper 111.

[0050] In one embodiment, preferably, the end of the workpiece 2 away from the sensor 3 is abutted against a first positioning member 6. The first positioning member 6 can position the relative position of the workpiece 2, thereby making the sensor 3 detect the workpiece 3 more accurately.

[0051] Preferably, a second positioning member 7 is installed on the outer wall of the sensor 3. Those skilled in the art can fix the relative position of the sensor 3 by means of the second positioning member 7. The above arrangement can further make the detection of the sensor 3 more accurate.

The embodiments of data acquisition, processing, output, judgment methods, etc. after these modifications or deformations can still fall within the scope of the optional implementation plans of this application.

[0053] Although the present application has been described through embodiments, those skilled in the art will appreciate that there are many modifications and changes to the present application without departing from the spirit of the present application. It is intended that the attached embodiments include these modifications and changes without departing from the present application.
