[0015] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application (for the convenience of description and understanding, the following is Figure 2 All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0016] See also Figure 1-3The present application provides a technical solution: a welding pull-out detection device for a heating wire, comprising a work surface 3, the upper surface of the work surface 3 is provided with a guide shaft mounting seat 4, a connecting long shaft 13 is sleeved in the guide shaft mounting seat 4, and the connecting long shaft 13 is connected to the telescopic end of a telescopic cylinder 2 arranged on the lower surface of the work surface 3.

[0017] The work surface 3 is the basic support platform of the entire device, and the work surface 3 provides a stable installation foundation and operating space for other components.

[0018] The guide shaft mounting seat 4 provides precise guidance and support for the connecting long shaft 13; a finely machined inner hole is provided in the guide shaft mounting seat 4, and the inner hole size is precisely matched with the outer diameter of the connecting long shaft 13, so that the connecting long shaft 13 can slide smoothly therein, while limiting its radial and circumferential degrees of freedom, ensuring that it can only move along a preset straight line direction. The accuracy of the movement of the connecting long shaft 13 is ensured, and detection errors caused by deflection or vibration are prevented.

[0019] The connecting long shaft 13 is tightly matched with the inner hole of the guide shaft mounting seat 4 to achieve precise guiding; when the telescopic cylinder 2 is working, the telescopic action of its telescopic end will be converted into linear motion through the connecting long shaft 13, thereby driving the heating wire clamping seat 12 to move up and down, completing the clamping, lifting, lowering and pulling operations of the heating wire; to withstand the large load generated during the drawing process and maintain good rigidity and stability.

[0020] A support frame 6 is arranged on the connecting long axis 13, an upper support frame 7 is arranged on the support frame 6, guide shafts 9 are arranged around the lower surface of the upper support frame 7, cross braces are arranged between the guide shafts 9, and hanging blocks 5 are arranged between the cross braces.

[0021] The support frame 6 is used to support the upper bracket 7 and provide a relatively independent and stable bearing platform for the upper bracket 7. The upper bracket 7 has sufficient strength and rigidity to cope with various stresses generated during the drawing process and ensure the stable operation of the upper structure.

[0022] The guide support shaft 9 is located around the lower surface of the upper bracket 7, and the guide support shaft 9 provides precise guidance for the cross support bracket; through its own linear bearing or ball bearing structure, it ensures that the cross support bracket moves smoothly along the preset path during the pulling process, reduces undesirable phenomena such as deflection and shaking, and ensures the accuracy of the pulling test.

[0023] The cross brace bracket is installed between the guide support shafts 9, and the cross brace bracket plays the role of connecting and supporting the suspension block 5. It has sufficient strength and bending resistance to resist the bending force and torsional force generated during the drawing process, ensuring the stable posture of the suspension block 5 and the heating wire clamping seat 12.

[0024] A heating wire clamping seat 12 is arranged in the middle of the hanging support block 5 , and the heating wire clamping seat 12 is arranged corresponding to a heating wire placement seat 14 arranged on the lower surface of the work table 3 . Tensile testers 11 are arranged on both sides of the hanging support block 5 .

[0025] The heating wire clamping seat 12 is the part that directly contacts the heating wire to be tested, and takes into account both the firmness of clamping and the protection of the heating wire.

[0026] The heating wire placement seat 14 corresponds to the heating wire clamping seat 12. It is used to place the heating wire to be tested before testing, ensuring that the heating wire is in the correct position and posture, so that the heating wire clamping seat 12 can clamp it.

[0027] The tension tester 11 monitors the tension of the heating wire in real time during the drawing process. It is connected to the suspension block 5 to convert the tension acting on the heating wire into an electrical signal, which is displayed on the instrument screen after processing for the operator to read and record.

[0028] Furthermore, a measuring support plate 10 is provided on the upper surface of the work table 3 , and the measuring support plate 10 is provided corresponding to a measuring card seat 16 provided on one side of the hanging support block 5 .

[0029] By measuring the relative position change of the support plate 16 to the measuring support plate 10, the displacement or deformation of the heating wire during the drawing process can be intuitively reflected.

[0030] Furthermore, guide shafts 15 are symmetrically arranged on the work surface 3 , and a heating wire placement seat 14 is sleeved between the guide shafts 15 .

[0031] The heating wire placement seat 14 is located on the guide shaft 15 and can move in a straight line along the guide shaft 15. According to the length of the heating wire, the position of the heating wire placement seat 14 on the guide shaft 15 can be adjusted so that the heating wire clamping seat 12 can conveniently clamp the heating wire.

[0032] Furthermore, the connecting long shaft 13 located at the upper end of the support frame 6 is sleeved with an adapter sleeve 8 .

[0033] Furthermore, a supporting leg 1 is provided on the lower surface of the work surface 3 .

[0034] Furthermore, the heating wire clamping seat 12 includes an installation guide shaft, a slot, an adjustment shaft and a welding wire clamping seat plate. The lower end of the installation guide shaft is provided with a slot, the two sides of the slot are sleeved with adjustment shafts, and the end of the adjustment shaft is provided with a welding wire clamping seat plate.

[0035] The installation guide shaft is connected to the suspension block 5 or other supporting structure, and a slot is provided at the lower end to cooperate with the adjustment shaft to form an adjustable clamping structure; by changing the position of the adjustment shaft in the slot (usually by rotation or sliding), the distance between the welding wire clamping plates can be adjusted to adapt to heating wires of different diameters or specifications; the surface of the welding wire clamping plate is finely polished or textured to increase the friction and clamping stability with the heating wire. At the same time, the design of the welding wire clamping plate must also take into account the protection of the heating wire to avoid damage to the surface of the heating wire during the clamping process.

[0036] When in use: place the heating wire to be tested on the heating wire placement seat 14 on the lower surface of the work table 3, and adjust the position of the heating wire placement seat 14 along the guide shaft 15 according to the length of the heating wire to ensure that both ends of the heating wire are aligned and in the correct position and posture.

[0037] Adjust the heating wire clamping seat 12 to rotate or slide the adjustment shaft so that its position in the slot adapts to the diameter of the heating wire, so that the distance between the welding wire clamping plates matches the diameter of the heating wire. Make sure that the surface of the welding wire clamping plate is flat and undamaged to protect the surface of the heating wire;

[0038] Set the maximum tension threshold of the tension tester 11; start the telescopic cylinder 2, drive the suspension block 5 to rise through the connecting long shaft 13, so that the heating wire clamping seat 12 clamps the heating wire;

[0039] The telescopic cylinder 2 extends, driving the support frame 6 to rise, and then driving the heating wire clamping seat 12 to pull the heating wire. The tension tester 11 monitors and displays the tension of the heating wire in real time during the pulling process;

[0040] At the same time, observe the relative position change of the measuring fixture 16 on the measuring support plate 10, record the displacement or deformation of the heating wire during the drawing process; and record the maximum tension value displayed by the tension tester 11, the tension value when it breaks, and the corresponding displacement or deformation.

[0041] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
