[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] Specific Embodiment 1: Please refer to Figures 1 to 7, in the embodiment of the present utility model, a device for detecting the welding strength of a sheet metal part includes a frame 1 and a control panel 3. Various parameters of the driving parts on the machine table can be set on the control panel 3. A workbench 2 is installed on the frame 1, and the control panel 3 is fixed on the workbench 2. A positioning fixture 5 is slidably installed above the workbench 2. The positioning fixture 5 is slidably connected to the workbench 2 through a first driving part 8. The positioning fixture 5 slides along the Y-axis direction of the workbench 2. A pushing mechanism 6 is installed at the rear side of the positioning fixture 5. The pushing mechanism 6 is used to contact and push the workpiece 9 on the positioning fixture 5. The pushing mechanism 6 is fixed on the workbench 2. A pressing mechanism 4 is installed above the positioning fixture 5. The pressing mechanism 4 is used to press and position the workpiece 9 on the positioning fixture 5. The pressing mechanism 4 is fixedly installed with the workbench 2.

[0020] The positioning fixture 5 includes a body seat 501 and baffles 502 vertically fixed at the left and right ends of the body seat 501. The length and width of the positioning fixture 5 match the external dimensions of the workpiece 9. The workpiece 9 to be tested includes a main body 901 and side plates 902. The side plates 902 are vertically fixed on one side of the top end of the main body 901. There are downward-bending bending parts on the front and rear sides of the main body 901, namely a first bending part 901-1 and a second bending part 901-2. The workpiece 9 is inserted and clamped on the body seat 501 of the positioning main body 901 through the first bending part 901-1 and the second bending part 901-2, and the side plates 902 are on the side close to the pushing mechanism 6.

[0021] In this embodiment, the pressing mechanism 4 includes a first support frame 401, a second driving part 402, and a pressing plate 403. The first support frame 401 is of a gantry structure and is fixed on the workbench 2. The second driving part 402 is fixed above the first support frame 401. The pressing plate 403 is installed with the second driving part 402 and is below the second driving part 402. The second driving part 402 drives the pressing plate 403 to move up and down to press the workpiece 9 on the positioning fixture 5.

[0022] The pushing mechanism 6 includes a second support frame 601 and several third driving parts 602 with the same structure. In this embodiment, four third driving parts 602 are adopted. The four third driving parts 602 are arranged side by side above the second support frame 601 and at the rear side of the positioning fixture 5. The second support frame 601 is fixedly installed with the workbench 2. A pushing plate 603 is installed on the third driving part 602. The third driving part 602 drives the pushing plate 603 to move towards the positioning fixture 5.

[0023] A material pushing mechanism 7 is further provided below the positioning fixture 5. The material pushing mechanism 7 includes a fourth driving member 701 and a material pushing plate 702. The fourth driving member 701 is fixed below the workbench 2. The material pushing plate 702 is installed on the fourth driving member 701 and above the fourth driving member 701. The material pushing plate 702 is on the front side of the positioning fixture 5, that is, the material pushing plate 702 is at the position below the first bending portion 901-1 of the workpiece 9. The fourth driving member 701 drives the material pushing plate 702 to move up and down to lift the workpiece 9 on the positioning fixture 5. After the test is completed, since the workpiece 9 is clamped on the positioning fixture 5, it is sometimes inconvenient to directly take it. The first bending portion 901-1 of the workpiece 9 can be lifted upward by the material pushing plate 702.

[0024] In this embodiment, the first driving member 8, the second driving member 402, the third driving member 602, and the fourth driving member 701 are all cylinder driving structures of the prior art.

[0025] Working principle: After the workpiece 9 to be tested is correspondingly clamped into the positioning fixture 5 manually or by a manipulator, the first driving member 8 drives the positioning fixture 5 to move towards the material pushing mechanism 6 until it reaches below the pressing plate 403. The pressing plate 403 moves downward under the drive of the second driving member 402 to press the workpiece 9. The material pushing plate on the material pushing mechanism 6 moves towards the workpiece 9 under the drive of the third driving member 602. The material pushing plate presses the side plate 902 until the strength reaches the set parameters. The material pushing plate and the pressing plate 403 reset. The material pushing plate 702 lifts the workpiece 9 to separate the first bending portion 901-1 and the second bending portion 901-2 from the positioning fixture 5. After the positioning fixture 5 moves to the outside through the first driving member 8, it is taken and unloaded manually or by a manipulator, and the operation is repeated.

[0026] Compared with the prior art, a sheet metal part welding strength detection device of the present application is easy to operate. The side plate position on the workpiece is pushed and pressed for testing through the material pushing mechanism. Whether the side plate and the main body are separated is detected according to the set pushing and pressing strength. If no fracture occurs after reaching the standard degree, it means that the sheet metal part meets the standard, otherwise it does not. The detection speed is fast and accurate, effectively improving the detection efficiency of the sheet metal part.
