[0031] As shown in Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 and Figure 6 The false welding detection tool includes a base 1 in the shape of a long plate, a placement plate 2, a limiting assembly, a pressing assembly, and a detection assembly. The limiting assembly is connected to the upper portion of the base 1. The placement plate 2 is in the shape of a long plate and is detachably connected to the upper portion of the base 1. When the placement plate 2 is connected to the base 1, the limiting assembly abuts against the left edge of the placement plate 2. The pressing assembly is connected to the right edge of the placement plate 2. After the pressing assembly is connected to the base 1, the pressing assembly can tightly press the placement plate 2 between the pressing assembly and the base 1. The upper portion of the placement plate 2 has a working portion 2a for placing a workpiece. The detection assembly is connected to the base 1, and the detection end of the detection assembly can extend into the working portion 2a to perform corresponding detection work.
[0032] Under the action of the pressing assembly, the placement plate 2 can be stably positioned on the upper portion of the base 1. After the detection end of the detection assembly extends into the working portion 2a, stable false welding detection can be achieved.
[0033] During the detection process, the limiting assembly can also appropriately apply a pushing force to the placement plate 2, thereby ensuring the stability of the test.
[0034] Of course, after the test work is completed, since the placement plate 2 is detachably connected to the base 1, the tested workpiece can be conveniently installed and taken out.
[0035] The limiting assembly includes a cylinder 3, a limiting rod 5, and an elastic reset mechanism. The sliding rail 4 and the cylinder 3 are both fixedly connected to the base 1. The limiting rod 5 is connected to the base 1 through the elastic reset mechanism and has a tendency to move toward the cylinder 3 under the action of the elastic reset mechanism. The cylinder 3 is opposite to the limiting rod 5, and the cylinder 3 can push the limiting rod 5.
[0036] Under the action of the elastic reset mechanism, the limiting rod 5 always has a tendency to abut against the placement plate 2. Therefore, during the test, the tested workpiece can also be subjected to a pushing force, thereby ensuring the stability of the test.
[0037] The elastic reset mechanism comprises a fixed block 6, a guide rod 7 and a spring 8, the fixed block 6 is fixedly connected at the edge of the base 1, the inner end of the guide rod 7 is fixedly connected on the fixed block 6, the inner side of the limiting rod 5 is provided with a recessed guide hole matched with the outer end of the guide rod 7, the outer end of the limiting rod 5 is embedded in the guide hole, and the spring 8 is tightly pressed at the bottom of the guide hole of the limiting rod 5.
[0038] The limiting rod 5 has a tendency to approach the cylinder 3 under the elastic force of the spring 8, and the cylinder 3 can control whether the placement plate 2 is subjected to the elastic force of the spring 8 after the cylinder 3 is actuated.
[0039] The outer end of the guide rod 7 is provided with a recessed spring hole 7a, and one end of the spring 8 is embedded in the spring hole 7a.
[0040] Such a structure can reduce the space occupied by the spring 8.
[0041] The base 1 is further fixedly connected with guide rails 9, and the lower part of the limiting rod 5 is embedded in the guide rails 9.
[0042] The number of the guide rails 9 is two, and the two guide rails 9 are arranged in parallel, the lower part of both ends of the limiting rod 5 is provided with a sliding block 10, the sliding block 10 is arranged in one-to-one correspondence with the guide rails 9, and the sliding block 10 is connected to the corresponding guide rail 9.
[0043] The cooperation of the guide rails 9 and the sliding blocks 10 can ensure the stable translation of the limiting rod 5.
[0044] The upper part of both ends of the limiting rod 5 is provided with a protruding limiting block 11, and the limiting block 11 can abut against the edge of the placement plate 2.
[0045] The protruding limiting block 11 can stably push the placement plate 2.
[0046] The number of the limiting assemblies is two, and the two limiting assemblies are arranged adjacent to each other and can abut against the adjacent two edges of the placement plate 2, respectively.
[0047] The two adjacent limiting assemblies can limit the adjacent two edges of the placement plate 2, and can appropriately provide a pushing force to the placement plate 2.
[0048] The abutting assembly comprises a buckling member 12 and a pressing plate 13 in the shape of a long plate, the inner edge of the pressing plate 13 is hinged to the edge of the placement plate 2, the buckling member 12 is connected to the base 1, and the buckling member 12 can be connected to the outer edge of the pressing plate 13.
[0049] In the initial state, the pressing plate 13 is away from the base 1.
[0050] After the pressing plate 13 swings around the hinge, the pressing plate 13 can be stably buckled and connected to the base 1. Of course, at this time, the placement plate 2 is buckled by the pressing plate 13.
[0051] The buckle member comprises a buckle base 12a, a buckle rod 12b, a connecting rod 12c and a spring 12d, the buckle base 12a is fixedly connected to the base 1, the inner end of the connecting rod 12c is fixedly connected to the lower end of the buckle rod 12b, the middle part of the connecting rod 12c is arranged in the buckle base 12a, and the outer end of the connecting rod 12c has a protruding head 12c1, the spring 12d is arranged between the middle part of the buckle rod 12b and the buckle base 12a, and the buckle rod 12b has a tendency to move away from the buckle base 12a under the elastic force of the spring 12d, and the head 12c1 abuts against the buckle base 12a.
[0052] The buckle rod 12b moves away from the buckle base 12a under the elastic force of the spring 12d, and when the pressing plate 13 contacts the buckle rod 12b, the buckle rod 12b always abuts against the edge of the pressing plate 13, thereby finally ensuring the stability of the buckle.
[0053] The upper end of the buckle rod 12b has a buckle hook 12b1 protruding from the side thereof, and the buckle hook 12b1 can be buckled to the outer edge of the pressing plate 13.
[0054] Of course, in order to facilitate the buckling of the pressing plate 13, the upper end of the buckle hook 12b1 has a smooth transition guide surface, and in the embodiment, the guide surface is an inclined surface of the upper part of the buckle hook. When the pressing plate is buckled, the edge of the pressing plate can smoothly enter the lower part of the buckle hook along the guide surface.

[0056] The cylinder 14 drives the guide plate 16 to move. Since the guide plate 16 contacts the sliding rail 15, the guide plate 16 can stably translate, and the test head 17 on the guide plate 16 can stably enter the working part after moving, thereby completing the corresponding detection work.
[0057] Since the workpiece is positioned on the placing plate, the limiting assembly one and the limiting assembly two can exert appropriate thrust force, whether the workpiece welding part can meet the design requirements after testing, that is, whether it can withstand appropriate thrust force, so that the test stability is high and the test content is rich.
