DETAILED DESCRIPTION

[0022] 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 the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0023] This embodiment provides a probe automatic testing tool, which realizes rapid testing of the test piece. No manual operation is required during the testing process. The detection length of the probe can be adjusted by increasing or decreasing the number of mounting blocks 40 according to the testing requirements of the test piece, thereby meeting the testing requirements of the test piece.

[0024] Combine Figures 1 to 3 As shown, the probe automatic testing tooling of this embodiment includes a positioning part 10, a testing part 20 and a control part 30. The positioning part 10 can install and position the test piece, the testing part 20 can perform probe testing on the positioned test piece, and the control part 30 can realize the overall control of the tooling and conduct information exchange.

[0025] In this embodiment, the probe automatic testing tool also includes a frame 50, and the positioning part 10, the testing part 20 and the control part 30 are all located on the frame 50. A control button 60 is provided on the frame 50, and the control button 60 is connected to the control part 30 to control the start and stop operation of the probe test to realize automatic testing of the test piece.

[0026] Furthermore, the control unit 30 of this embodiment is a control box, which is arranged on the frame 50 to achieve overall control of the test tooling.

[0027] Combine Figure 1 and Figure 3 As shown, the positioning portion 10 of this embodiment includes a bottom block 11 and a positioning pin 12. The positioning pin 12 is arranged on the bottom block 11. There are multiple positioning pins 12 and they are evenly installed on the bottom block 11. A positioning protrusion 121 is provided on the top of the positioning pin 12 to position the workpiece to be tested. The positioning pins 12 of this embodiment are located at the four corner positions of the bottom block 11. The positioning protrusion 121 on the positioning pin 12 accurately positions the workpiece to be tested to ensure the smooth progress of subsequent tests.

[0028] Combine Figure 1 and Figure 2 As shown, the test part 20 of this embodiment includes a drive module 21, a test head 22 and a probe body 23. A number of mounting blocks 40 are provided on the test head 22. The probe body 23 passes through the mounting blocks 40 and is installed on the test head 22. The drive module 21 drives the test head 22. There are three mounting blocks 40 and they are stacked. The part of the probe body 23 protruding from the mounting blocks 40 is the detection part. In the actual use of the probe automatic test tooling, if the detection part of the probe body 23 needs to be lengthened, the number of the mounting blocks 40 can be subtracted. If the detection part of the probe body 23 needs to be shortened, the number of the mounting blocks 40 can be increased. In this way, the detection part of the probe body 23 can be quickly adjusted to adapt to test pieces of different specifications and meet test requirements.

[0029] In this embodiment, the driving module 21 includes a mounting frame 211, a motor 212, a screw 213 and a moving block 214. The motor 212 drives the screw 213 to rotate to drive the moving block 214 to move along the length direction of the screw 213. The test head 22 is fixedly connected to the moving block 214. Under the driving action of the driving module 21, the test head 22 is driven to enable the probe body 23 to approach the piece to be tested and test the piece to be tested.

[0030] Furthermore, a plurality of guide rods 70 are provided on the mounting frame 211 of this embodiment. The guide rods 70 pass through the moving block 214. When the moving block 214 moves, the guide rods 70 can stably guide the moving block 214, thereby improving the test accuracy.

[0031] In actual use, the probe automatic testing fixture of this embodiment is installed on the positioning part 10, and the driving module 21 of the testing part 20 drives the test head 22 to approach the piece to be tested. After the probe body 23 completes the test of the piece to be tested, it can be reset. When it is necessary to adjust the length of the detection part of the probe body 23, if the detection part of the probe body 23 needs to be lengthened, the number of mounting blocks 40 can be subtracted. If the detection part of the probe body 23 needs to be shortened, the number of mounting blocks 40 can be increased. In this way, the detection part of the probe body 23 can be quickly adjusted to adapt to pieces to be tested of different specifications and meet the testing requirements of the pieces to be tested.

[0032] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
