[0022] 1. When detecting an automotive workpiece, the automotive workpiece is placed on the surface of the tooling housing and positioned by the test piece positioning member. Then, the positioning member driving member drives the automotive workpiece to move towards the profiling module. During the connection between the profiling module and the automotive workpiece, when there is a positioning error between the profiling module and the automotive workpiece, the profiling module can move relative to the test positioning frame under the action of the connection force provided by the positioning member driving member, thereby automatically adjusting the position of the profiling module to align the profiling module with the automotive workpiece and perform the connection, reducing the probability of damage at the connection between the automotive workpiece and the profiling module and improving the quality of the finished automotive workpiece.

[0023] 2. In the initial state, there is a gap between the connecting plate and the outer wall of the test positioning frame under the action of the moving spring. When the automotive workpiece moves towards the connecting plate under the action of the test piece positioning member and the positioning member driving member and abuts against the connecting plate, the moving spring is compressed. At this time, if the automotive workpiece and the profiling module are not completely aligned, the connecting plate will move relative to the test positioning frame under the action of the binding force provided by the positioning member driving member, causing the profiling module connected to the connecting plate to move and align with the connection port of the automotive workpiece.

[0024] 3. By adopting the method of driving the automotive workpiece to move instead of driving the profiling module to move, the probability of damage to the profiling module due to movement is reduced, thereby reducing the maintenance cost of the test tooling. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0032] The following will further elaborate on the present application in conjunction with the attached Figure 1-6 drawings.

[0033] The embodiment of the present application discloses an EOL test tooling. Referring to Figure 1 and Figure 2 , an EOL test tooling includes a tooling housing 1, a test positioning frame 2, a profiling module 3, a test piece positioning member 4, and a positioning member driving member 5.

[0034] The test positioning frame 2 is fixedly installed on the upper surface of the tooling housing 1. The profiling module 3 is connected to one side of the test positioning frame 2 and can move relative to the test positioning frame 2. The test piece positioning member 4 is arranged close to the profiling module 3. The bottom end of the test piece positioning member 4 is connected to a positioning member driving member 5 that can move towards the profiling module 3. Two buttons electrically connected to the positioning member driving member 5 are arranged on the tooling housing 1.

[0035] When testing an automotive workpiece, the automotive workpiece is placed on the test piece positioning member 4 for positioning. After the automotive workpiece is positioned, the operator presses the two buttons simultaneously with both hands, so that the positioning member driving member 5 drives the automotive workpiece positioned by the test piece positioning member 4 to move towards the test positioning frame 2. When the operator presses only one button, the positioning member driving member 5 drives the test piece positioning member 4 to move away from the test positioning frame 2. When the automotive workpiece abuts against the profiling module 3 connected to the test positioning frame 2 and there is a positioning error between the profiling module 3 and the automotive workpiece, the profiling module 3 moves relative to the test positioning frame 2, thereby reducing the positioning error and realizing the connection between the profiling module 3 and the automotive workpiece. The probability of damage at the connection between the automotive workpiece and the profiling module 3 is reduced, and the quality of the finished automotive workpiece is improved.

[0036] Referring to Figure 1And Figure 2 The test piece positioning member 4 includes a positioning plate 41 and positioning blocks 42. The number of the positioning blocks 42 can be selected as 4, 6, or 8. The positioning blocks 42 are bolted to the upper surface of the positioning plate 41, and the automotive workpiece is fixed between different positioning blocks 42. The lower surface of the positioning plate 41 is bolted to the positioning member driving member 5.

[0037] After the automotive workpiece is positioned by the positioning blocks 42, under the action of the positioning member driving member 5, the automotive workpiece moves in the direction of the profiling module 3. After the test is completed, the positioning member driving member 5 drives the automotive workpiece to separate from the profiling module 3.

[0038] Refer to Figure 1 And Figure 3 The tooling housing 1 includes an upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 are connected by a hinge, and an installation space 13 is formed between the upper housing 11 and the lower housing 12. A communication port 111 communicating with the installation space 13 is opened on the upper end surface of the upper housing 11. An air spring 9 is arranged in the installation space 13. One end of the air spring 9 is hinged to the inner wall of the lower housing 12, and the other end of the air spring 9 can abut against the inner wall of the upper housing 11 to provide support when the upper housing 11 and the lower housing 12 are opened, reducing the probability of the natural closing of the upper housing 11 and the lower housing 12.

[0039] Refer to Figure 1-Figure 4 The positioning member driving member 5 includes a driving cylinder 51, a driving abutting plate 52, a moving slider 53, and a moving slide rail 54. The driving cylinder 51 is installed inside the installation space 13, and an air source inlet 14 communicating with the installation space 13 is opened on the lower housing 12. One end of the driving abutting plate 52 is located inside the installation space 13 and fixedly connected to the telescopic end of the driving cylinder 51. The other end of the driving abutting plate 52 passes through the communication port 111 and is located on the surface of the upper housing 11 and fixedly connected to the positioning plate 41. The moving slider 53 is bolted to the bottom end of the positioning plate 41, and the bottom end of the moving slider 53 is slidably connected to the moving slide rail 54. The moving slide rail 54 is fixedly connected to the upper end surface of the upper housing 11.

[0040] When the driving cylinder 51 expands and contracts, it drives the positioning plate 41 to move through the driving abutting plate 52. The moving slider 53 and the moving slide rail 54 reduce the resistance of the positioning plate 41 during movement, thereby facilitating the movement of the positioning plate 41.

[0041] Refer to Figure 1 And Figure 5, on the side of the profiling module 3 facing away from the test positioning frame 2, a connecting plate 6 is fixedly connected. A first bolt hole 61 is provided on the connecting plate 6, and a second bolt hole 21 is provided on the side of the test positioning frame 2 facing the profiling module 3. A connecting bolt 7 is provided between the connecting plate 6 and the test positioning frame 2. One end of the connecting bolt 7 is slidably connected to the first bolt hole 61, the other end of the connecting bolt 7 is fixedly connected to the second bolt hole 21, and a moving spring 8 is sleeved on the side wall of the connecting bolt 7.

[0042] Referring to Figure 5 and Figure 6 , the connecting bolt 7 includes a connecting nut 71, a first connecting column 72, a second connecting column 73, and a connecting cap 74 that are fixedly connected in sequence. The cross-sectional diameter of the connecting nut 71 is greater than the cross-sectional diameter of the first connecting column 72, the cross-sectional diameter of the first connecting column 72 is greater than the cross-sectional diameter of the second connecting column 73, and the cross-sectional diameter of the connecting cap 74 is between the first connecting column 72 and the second connecting column 73. The moving spring 8 is sleeved on the first connecting column 72, and the inner diameter of the moving spring 8 is greater than the cross-sectional diameter of the first connecting column 72. When the connecting nut 71 abuts against the connecting plate 6, there is a gap between the connecting plate 6 and the test positioning frame 2.

[0043] When the automotive workpiece abuts against the profiling module 3, if there is a positioning error between the automotive workpiece and the profiling module 3, the automotive workpiece gives a thrust to the profiling module 3, causing the profiling module 3 and the connecting plate 6 to move towards the test positioning frame 2. During the movement of the profiling module 3, due to the cooperation between the chamfer on the profiling module 3 and the interface on the automotive workpiece, a moving force is given to the connecting plate 6, causing the connecting plate 6 to move, and further aligning the interfaces on the profiling module 3 and the automotive workpiece, realizing the connection between the automotive workpiece and the profiling module 3.

[0044] Referring to Figure 1 and Figure 4 , a power interface 22 is provided on the side of the test positioning frame 2 facing away from the connecting plate 6. The wire is connected to the profiling module 3 through the power interface 22. When there are too many wires connected to the power interface 22, a wire harness is arranged to bundle the wires.

[0045] The implementation principle of an EOL test tooling in an embodiment of the present application is as follows: When the automotive workpiece is undergoing EOL testing, the automotive workpiece is clamped and fixed by the test piece positioning member 4, and the positioning member driving member 5 drives the test piece positioning member 4 and the automotive workpiece to move towards the profiling module 3 on the connecting test positioning frame 2, causing the automotive workpiece to abut against the profiling module 3. When there is a positioning error between the profiling module 3 and the automotive workpiece, the profiling module 3 can move relative to the test positioning frame 2, aligning the profiling module 3 with the interface on the automotive workpiece, reducing the probability of damage at the connection between the automotive workpiece and the profiling module 3, and improving the quality of the finished automotive workpiece.

[0046] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
