Description

Technical Field

[0001] This utility model relates to the field of detonator welding strength testing technology, specifically a detonator welding strength tester. Background Technology

[0002] In the detonator manufacturing process, the welding strength between the lead wire and the detonator shell is a key indicator to ensure product reliability and safety.

[0003] Traditional detonator welding strength testing equipment typically only tests axial tensile force (i.e., vertical pull-out force), evaluating the tensile performance of the weld joint by applying unidirectional tensile force.

[0004] However, in real-world applications, detonator leads may be subjected to circumferential torsional forces due to improper installation, transportation, or operation (such as lead entanglement or accidental twisting). Axial tensile testing alone cannot fully reflect the comprehensive mechanical properties of the welded parts.

[0005] Therefore, we propose a detonator welding strength tester. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a detonator welding strength tester that integrates axial tensile force and circumferential torsional force testing functions, improving the accuracy of testing the welding strength between lead wire and detonator, and effectively solving the problems in the background technology.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a detonator welding strength tester, comprising a processing table, a bracket fixedly installed on the lower outer surface of the processing table, a circumferential torsion structure fixedly installed in the middle of the upper outer surface of the processing table, a fixing plate fixedly installed on one side of the upper outer surface of the processing table, and an axial tension structure fixedly installed on the upper part of the front outer surface of the fixing plate. The circumferential torsion structure includes a mounting box, a motor, a power shaft, a load shaft, a torque sensor, a second mounting block, a worm gear and a worm wheel. The axial tension structure includes a fixing block, a hydraulic rod, a connecting shaft, a first mounting block, a tension sensor, an arm plate, a guide rod, a fixing arm and a guide ring. A lead wire fixing clamp is fixedly installed on the lower outer surface of the first mounting block, and a detonator fixing clamp is fixedly installed on the upper outer surface of the second mounting block. The fixing block is fixed to the top of the front outer surface of the fixing plate, and the mounting box is fixed to the middle of the upper outer surface of the processing table.

[0008] Preferably, the hydraulic rod is fixed on the fixing block, the connecting shaft is fixed on the lower outer surface of the piston rod in the hydraulic rod, and the tension sensor is fixed between the middle of the upper outer surface of the first mounting block and the lower outer surface of the connecting shaft.

[0009] Preferably, the arm plate is fixed to one side of the outer surface of the connecting shaft, the guide rod is fixed to the upper outer surface of the arm plate, the fixed arm is fixed to one side of the outer surface of the fixed block, the guide ring is opened on the upper outer surface of the fixed arm, the guide ring extends to the lower outer surface of the fixed arm, and the outer wall of the guide rod and the guide ring are slidably connected.

[0010] Preferably, the motor is fixed to one outer surface of the mounting box, the worm and the worm wheel are both located inside the mounting box, the worm is located on one outer surface of the worm wheel, the worm wheel is fixed to the outer wall of the lower part of the power shaft, and one outer surface of the worm and one outer surface of the worm wheel mesh with each other.

[0011] Preferably, a coupling is provided between the worm and the motor, and the outer surface of one end of the worm is fixedly connected to the outer surface of one end of the output shaft of the motor through the coupling. Bearings are provided between the worm, the drive shaft and the mounting box, and the worm and the drive shaft are rotatably connected to the mounting box through the bearings.

[0012] Preferably, the upper outer surface of the load shaft is fixedly connected to the middle of the lower outer surface of the second mounting block, and a coupling is provided between the torque sensor and both the load shaft and the power shaft. The torque sensor is installed between the upper end of the power shaft and the lower end of the load shaft through the coupling.

[0013] Compared with the prior art, this utility model provides a detonator welding strength tester, which has the following beneficial effects: This detonator welding strength tester integrates the axial tensile force structure and the circumferential torsion structure into the same testing platform, enabling the testing of axial tensile force and circumferential torsion force at the detonator welding site on a single device. This avoids the cumbersome operation of using different devices for separate testing as in traditional methods, significantly improving testing efficiency and reducing testing costs.

[0014] This detonator welding strength tester uses a worm gear reduction transmission in its circumferential torsion structure, which has a self-locking characteristic to prevent accidental rotation caused by reverse force during the test and ensure test safety. Attached Figure Description

A lead wire fixing clamp 11 is fixedly mounted on the lower outer surface of the first mounting block 9, and a detonator fixing clamp 22 is fixedly mounted on the upper outer surface of the second mounting block 21. The fixing block 6 is fixed to the top of the front outer surface of the fixing plate 4, and the mounting box 16 is fixed to the middle of the upper outer surface of the processing table 1.

[0023] Hydraulic rod 7 is fixed to fixed block 6. Connecting shaft 8 is fixed to the lower outer surface of piston rod in hydraulic rod 7. Tension sensor 10 is fixed between the middle of the upper outer surface of first mounting block 9 and the lower outer surface of connecting shaft 8. Arm plate 12 is fixed to one side outer surface of connecting shaft 8. Guide rod 13 is fixed to the upper outer surface of arm plate 12. Fixed arm 14 is fixed to one side outer surface of fixed block 6. Guide ring 15 is opened on the upper outer surface of fixed arm 14 and extends to the lower outer surface of fixed arm 14. The outer wall of guide rod 13 and guide ring 15 are slidably connected. Motor 17 is fixed to one side outer surface of mounting box 16. Worm 23 and worm wheel 24 are both located inside mounting box 16. Worm 23 is located on one side outer surface of worm wheel 24. The worm gear 24 is fixed to the outer wall of the lower part of the power shaft 18, and one side of the outer surface of the worm 23 meshes with one side of the outer surface of the worm gear 24. A coupling is provided between the worm 23 and the motor 17. One end of the outer surface of the worm 23 is fixedly connected to one end of the outer surface of the output shaft of the motor 17 through the coupling. Bearings are provided between the worm 23, the power shaft 18 and the mounting box 16. The worm 23 and the power shaft 18 are rotatably connected to the mounting box 16 through the bearings. The upper outer surface of the load shaft 19 is fixedly connected to the middle part of the lower outer surface of the second mounting block 21. A coupling is provided between the torque sensor 20 and the load shaft 19 and the power shaft 18. The torque sensor 20 is installed between the upper end of the power shaft 18 and the lower end of the load shaft 19 through the coupling.

[0024] It should be noted that this utility model is a detonator welding strength tester. The detonator fixing clamp 22 and the lead wire fixing clamp 11 described in this article are both existing technologies. The detonator is fixed by the detonator fixing clamp 22 and the lead wire is fixed by the lead wire fixing clamp 11. This is readily known to those skilled in the art, and will not be elaborated further. During testing, the detonator is clamped and fixed by the detonator fixing clamp 22 and the lead wire is fixed by the lead wire fixing clamp 11. Then the test begins. First, an axial tensile test is performed. The operation of the hydraulic rod 7 drives the first mounting block 9 to rise, applying tension to the lead wire. When the hydraulic rod 7 drives the connecting shaft 8 to rise, it drives the guide rod 13 to slide along the guide ring 15, improving the stability of the lifting and lowering of the first mounting block 9. Qualitatively, the tensile force is detected by the tensile sensor 10. The test ends when the value of the increased tensile force decreases or becomes zero. For the torsional force test, the sample is still fixed by the lead wire fixing clamp 11 and the detonator fixing clamp 22. Then, the lead wire is straightened by the operation of the axial tensile structure 5. The motor 17 drives the worm gear 23 to rotate, which in turn drives the power shaft 18 through the worm wheel 24. The power shaft 18 then drives the second mounting block 21 and the detonator fixing clamp 22 to rotate. The torque sensor 20 detects the change in torque. The test ends when the value decreases or becomes zero. The circumferential torsion structure 3 and the axial tensile structure 5 integrate axial tensile and circumferential torsional force testing functions, improving the accuracy of the test.
