The fixed base is installed on the top of the testing table, and a first through groove is opened at the bottom of the fixed base. Two stepped surfaces are provided on one side of the fixed base, respectively located on both sides of the first through groove, and a through hole is opened at the top of the fixed base. The force application component includes a drive source, a pressure block, and a tension / compression sensor. The drive source is located on the top of the fixed base, and the pressure block is slidably connected in the through hole. The top of the pressure block is connected to the output end of the drive source through the tension / compression sensor. By setting the stepped surfaces and the first through groove, when the crossbar of the workpiece is placed on the stepped surface, the support rod below is suspended. The pressure block driven by the drive source presses down on the support rod. The tension / compression sensor connected between the pressure block and the drive source detects the magnitude of the downward pressure in real time. The welding strength is determined by detecting the magnitude of the force when the welding position between the crossbar and the support rod is damaged.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0029] Example 1: Refer to Figures 1-5 As shown, the present invention provides a welding strength testing device, comprising:

[0030] Test bench 1;

[0031] The fixed base 2 is installed on the top of the test bench 1. The bottom of the fixed base 2 has a first through groove 21 extending along the Y-axis direction, and the side of the fixed base 2 has a second through groove extending along the X-axis direction to form two stepped surfaces 22 located on both sides of the first through groove. The top of the fixed base 2 has a through hole 23 extending along the Z-axis direction.

[0032] The force application component 3 includes a drive source 31, a pressure block 32, and a tension / compression sensor 33. The drive source 31 is located on the top of the fixed base 2. The pressure block 32 is slidably connected in the through hole 23. The top of the pressure block 32 is connected to the output end of the drive source 31 through the tension / compression sensor 33. A U-shaped notch 321 is provided at the bottom of the pressure block 32.

[0033] Specifically, when testing the welding strength of a workpiece, one end of a support rod of the workpiece is first inserted into the first through groove 21, and a crossbar is laid across the two stepped surfaces 22, with the position of the crossbar corresponding to the position of the notch 321 at the bottom of the pressure block 32. At this time, the end of the support rod inserted into the first through groove 21 is suspended in the air. When the drive source 31 drives the pressure block 32 to move downward, the bottom of the pressure block 32 applies a downward force to the crossbar. At the same time, the tension and pressure sensor 33 between the drive source 31 and the pressure block 32 detects the magnitude of the applied force in real time. When the drive source 31 applies a pressure exceeding the predetermined magnitude, the welding position between the crossbar and the support rod is broken, which proves that the welding strength is qualified.

[0034] This utility model discloses a welding strength testing device. By setting a stepped surface 22 and a first through groove 21, the support rod below the workpiece's crossbar is suspended when placed on the stepped surface 22. A pressure block 32 driven by a drive source 31 presses down on the support rod. A tension / compression sensor 33 connected between the pressure block 32 and the drive source 31 detects the magnitude of the downward pressure in real time. The welding strength is determined by detecting the force required when the weld between the crossbar and the support rod is damaged. The test is conducted using a downward pressure method, eliminating the need for connection between the testing device and the workpiece, thus simplifying the testing process. This effectively improves testing efficiency and reduces production costs for workpieces with numerous weld points. Furthermore, the entire device has a simple structure, is easy to operate, and possesses high practicality.

[0035] Reference Figure 5As shown, further, it includes a connecting rod assembly 4, which is provided in multiple sets. Each set of connecting rod assemblies 4 includes a connecting post 41 and a bolt 42. One end of the connecting post 41 is coaxially connected to a stud head 411 and screwed to the top of the fixing base 2 through the stud head 411. The other end of the connecting post 41 is coaxially provided with a threaded hole. One end of the bolt 42 is screwed into the threaded hole, and the other end is connected to the drive source 31. Specifically, the top of the fixing base 2 is symmetrically provided with multiple threaded connection holes. The connecting post 41 is screwed into each threaded connection hole through the stud head 411. Multiple bolts 42 are threadedly connected to the housing of the drive source 31, and each bolt 42 is screwed into the threaded hole of each connecting post 41. The drive source 31 can be easily installed and disassembled through the connecting rod assembly 4, which is convenient for maintenance.

[0036] Furthermore, the connecting post 41 is a round rod structure, and two flat positions 412 are symmetrically arranged on the side of the connecting post 41. The position and height of the driving source 31 can be finely adjusted by turning each connecting post 41 through the flat positions 412. The position and height of the driving source 31 can also be finely adjusted by adjusting the degree of tightening between the bolt 42 and the connecting post 41.

[0037] Reference Figure 2 As shown, further, a horizontal support plate 5 is connected to one side of the fixed base 2 by fasteners. A vertical handle 6 is connected to the support plate 5, and a control button 7 is installed on the handle 6. Specifically, during testing, the operator holds the handle 6 and controls the action of the drive source 31 by pressing the control button 7 on the handle 6.

[0038] Furthermore, it includes a controller, which connects to the drive source 31 and the control button 7.

[0039] Reference Figure 1 As shown, the system further includes a display screen 8, which is mounted on the test bench 1 and located on one side of the mounting base 2, and is connected to the controller. Specifically, the pressure value detected by the tension / compression sensor 33 can be displayed on the display screen 8 in real time.

[0040] Furthermore, the bottom of the test bench 1 is symmetrically equipped with multiple casters 11 with braking functions. The entire testing device can be easily moved to the designated workstation for testing.

[0041] Furthermore, the drive source 31 employs a hydraulic cylinder.

[0042] Furthermore, including hydraulic station 9, drive source 31 is connected to hydraulic station 9 via oil pipe, and pressure gauge is connected to oil pipe.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
