The above definitions are only for the purpose of explaining and illustrating the present disclosure, and should not be construed as a limitation to the present disclosure.

[0026] For the sake of easy understanding, the following Figures 1 to 2 refers to the accompanying drawings and describes in detail the specific structure and working principle of the present disclosure in combination with the embodiments.

[0027] The present disclosure relates to a picking needle for a welding force testing device, which can effectively adjust the position of the picking needle so that when the picking needle is performing measurement, it can be perpendicular to the surface to be measured, thereby obtaining a more accurate test result. Referring to Figure 1 and Figure 2 , the picking needle of the welding force testing device of the present disclosure includes a picking needle body 1, a connecting rod 2 and a limiting member 3. The picking needle body 1 is perpendicular to the axis of the connecting rod 2 and is used to contact the component to be tested for welding force. One end of the connecting rod 2 is used to connect with the welding force testing device, and the second end is provided with an adjusting member 4. The adjusting member 4 can rotate around the axis of the connecting rod 2. The picking needle body 1 is located in the adjusting member 4 and can rotate synchronously with the adjusting member 4 to adjust the angle of the picking needle body 1 relative to the object to be tested, ensuring that the picking needle body 1 can be perpendicular to the object to be tested. The limiting member 3 is used to limit the movement of the adjusting member 4. When the adjusting member 4 is in a suitable position so that the picking needle body 1 is perpendicular to the component to be tested, the limiting member 3 can fix the adjusting member 4, making the adjusting member 4 no longer able to rotate around the connecting rod 2, and ensuring the stability of the picking needle body 1 during the test process.

[0028] The needle pusher of the welding force testing device of the present disclosure is structured such that an adjusting member 4 that can rotate relative to the axis of the connecting rod 2 is provided on the connecting rod 2, and the needle pusher body 1 is connected to the adjusting member 4. When the staff finds that the needle pusher body 1 is not perpendicular to the object to be tested, they can adjust the angle of the needle pusher body 1 relative to the object to be tested by rotating the adjusting member 4, ensuring that the needle pusher body 1 is perpendicular to the object to be tested, without having to adjust its own position or rotate the welding force testing device to adjust the position of the needle pusher body 1. Thus, the welding force testing device applying the needle pusher of the present disclosure can obtain more accurate data during welding force testing, reducing system errors and the impact on subsequent operations.

[0029] In an embodiment of the present disclosure, referring to Figure 1 and Figure 2 , anti-slip patterns 44 are provided on the outer wall of the adjusting member 4. By providing the anti-slip patterns 44, the friction between the fingers of the staff and the outer wall of the adjusting member 4 can be increased, making it convenient for the staff to rotate the adjusting member 4. Referring to Figure 2 , in this embodiment, the anti-slip patterns 44 are triangular protrusions provided on the outer wall of the adjusting member 4. There are multiple triangular protrusions, evenly distributed circumferentially around the adjusting member 4, to increase the friction between the fingers of the staff and the outer wall of the adjusting member 4. Of course, in other embodiments, the anti-slip patterns 44 can also be in other forms, as long as they can achieve an anti-slip effect, and the present disclosure does not limit this.

[0030] In an embodiment of the present disclosure, referring to Figure 1 and Figure 2 , a connecting groove 41 is provided in the adjusting member 4. The connecting groove 41 is cylindrical, facilitating cooperation with most connecting rods 2 in the shape of round rods, and the inner wall of the connecting groove 41 also fits against the outer wall of the second end of the connecting rod 2, so that the adjusting member 4 does not shake during rotation, ensuring the stability of the adjusting member 4 on the connecting rod 2. In some embodiments of the present disclosure, the adjusting member 4 can also be cylindrical to facilitate rotation by the staff.

[0031] In an embodiment of the present disclosure, referring to Figure 1 and Figure 2 , a flange 21 is provided at the second end of the connecting rod 2. The connecting groove 41 is sleeved on the flange 21. By providing the flange 21, the radius of the second end of the connecting rod 2 and the size of the adjusting member 4 can be increased, making it more convenient for the staff to make adjustments. To prevent the adjusting member 4 from falling off the connecting rod 2, a clamping ring 42 is further provided on the adjusting member 4. The outer ring of the clamping ring 42 is connected to the inside of the connecting groove 41, and the radius of the inner ring is smaller than the radius of the flange 21, so that the adjusting member 4 can be clamped on the flange 21 to prevent the adjusting member 4 from falling off the connecting rod 2 during the process of adjusting the angle of the needle pusher body 1.

[0032] In one embodiment of the present disclosure, refer to Figure 1 and Figure 2 , an opening 43 is provided on the connecting groove 41, and the opening 43 penetrates through the outer wall of the adjusting member 4. By providing the opening 43, space can be provided for the dialing needle body 1 to extend out of the adjusting member 4. In this embodiment, the adjusting member 4 is cylindrical, the connecting groove 41 is a cylindrical groove provided in the adjusting member 4, and the opening 43 is a strip-shaped groove provided on the outer wall of the adjusting member 4 and having the same height as the adjusting member 4, so that the dialing needle body 1 inside the adjusting member 4 can extend out of the adjusting member 4 through the strip-shaped groove. Of course, in other embodiments, the opening 43 can also be of other shapes, as long as it can enable the dialing needle body 1 to extend out of the adjusting member 4, and the present disclosure does not limit this.

[0033] In one embodiment of the present disclosure, refer to Figure 1 and Figure 2 , a clamping groove 431 is provided at the opening 43. Through the clamping groove 431, the dialing needle body 1 can be clamped on the adjusting member 4 to prevent the dialing needle body 1 from falling off during use. In this embodiment, the clamping groove 431 is a groove provided on the opening 43 and capable of fitting with the outer wall of the dialing needle body 1, so that the dialing needle body 1 can be clamped in the adjusting member 4. After the clamping is completed, the dialing needle body 1 can be further fixed by the pressure between the flange 21 of the connecting rod 2 and the adjusting member 4 to ensure the stability of the dialing needle body 1 in the adjusting member 4. Of course, in other cases, the clamping groove 431 can also be of other structures, and an anti-slip pad can also be provided on the clamping groove 431 to increase the friction between the clamping groove 431 and the dialing needle body 1, further improving the stability of the dialing needle body 1 in the adjusting member 4, and the present disclosure does not limit this.

[0034] In one embodiment of the present disclosure, refer to Figure 1 and Figure 2 , the limiting member 3 includes a limiting bolt 31. A bolt hole is provided on the adjusting member 4. The end of the limiting bolt 31 passes through the outer wall of the adjusting member 4 through the bolt hole and abuts against the outer wall of the connecting rod 2 to limit the rotation of the adjusting member 4 relative to the connecting rod 2. Specifically, when adjusting the angle of the dialing needle body 1, the staff needs to first remove the limiting bolt 31, then rotate the adjusting member 4 to adjust the dialing needle body 1 to a suitable position, and then the staff can reinstall the limiting bolt 31 to complete the adjustment of the angle of the dialing needle body 1. Of course, in other embodiments, the limiting member 3 can also be of other types, as long as it can limit the rotation of the adjusting member 4, and the present disclosure does not limit this.

[0035] In one embodiment of the present disclosure, refer to Figure 1 and Figure 2, a plurality of limit bolts 31 are provided and distributed along the circumferential direction of the adjusting member 4. By providing a plurality of limit bolts 31, the limiting effect of the limit bolts 31 on the adjusting member 4 can be increased, and the adjusting member 4 can be prevented from rotating during use. In this embodiment, the adjusting member 4 is cylindrical, and three limit bolts 31 are provided and distributed along the circumferential direction of the adjusting member 4, and the position of the opening 43 is avoided. Of course, in other embodiments, only one limit bolt 31 or more can also be provided, and other distribution methods can be adopted, as long as the adjusting member 4 can be fixed, and details will not be elaborated here.

[0036] In an embodiment of the present disclosure, referring to Figure 1 and Figure 2 , the dial needle body 1 is fixedly connected to the adjusting member 4. Such a setting can integrate the dial needle body 1 and the adjusting member 4 into a whole, making it more convenient for replacement. For example, before use, different-sized adjusting members 4 and different-length dial needle bodies 1 can be prepared, and then the appropriate-sized and -length adjusting member 4 and dial needle body 1 can be selected according to the object to be tested and connected to the welding force testing device to achieve better testing effects and better applicability.

[0037] In a second aspect of the present disclosure, a welding force testing device is further provided. Referring to Figure 1 , it includes a welding force testing device body and the welding force testing device dial needle described in the above embodiment. Among them, the first end of the connecting rod 2 is connected to the welding force testing device body. When the welding force testing device of the present disclosure is in use, first, the first end of the connecting rod 2 needs to be connected to the welding device body, and then the staff can select a suitable adjusting member 4 and connect it to the second end of the connecting rod 2 according to the object to be tested. Then, the welding force of the object to be tested is tested. During the testing process, if the staff finds that the dial needle body 1 is not perpendicular to the object to be tested, the angle of the dial needle body 1 needs to be adjusted.

[0038] The adjustment process is as follows: First, the limit bolt 31 on the adjusting member 4 needs to be removed, then the adjusting member 4 is rotated according to the position of the object to be tested so that the dial needle body 1 on the adjusting member 4 can be rotated to a position perpendicular to the object to be tested, and finally the limit bolt 31 is reinstalled on the adjusting member 4 to complete the adjustment of the position of the dial needle body 1 in the welding force testing device.

[0039] The welding force testing device of the present disclosure is configured such that an adjusting member 4 that can rotate relative to the axis of the connecting rod 2 is provided on the connecting rod 2, and the dial needle body 1 is connected to the adjusting member 4. When the staff finds that the dial needle body 1 is not perpendicular to the object to be tested, they can adjust the angle of the dial needle body 1 relative to the object to be tested by rotating the adjusting member 4, ensuring that the dial needle body 1 can be perpendicular to the object to be tested, without having to adjust its own position or rotate the welding force testing device to adjust the position of the dial needle body 1. Thus, the welding force testing device using the dial needle of the present disclosure can obtain more accurate data during welding force testing, reducing the influence of errors on systematic errors and subsequent operations.
