[0018] Example:

[0019] Please see Figure 1-4 The speed sensor and chip multifunctional testing device shown includes a base plate 1, on which an XYZ adjustment slide 2 and a motor base 3 are mounted. A detection base plate 4 is fixedly connected to the moving platform of the XYZ adjustment slide 2. The detection base plate 4 is provided with an insertion hole 401 and a fixing groove 402. Clamping bolts 5 are threaded to the sides of the insertion hole 401 and the fixing groove 402. A chip test seat 6 is arranged between the clamping bolts 5 located at the fixing groove 402 on the detection base plate 4. A servo motor 7 is fixedly connected to the motor base 3. A signal wheel 701 is detachably connected to the rotating shaft of the servo motor 7.

[0020] Multiple mounting holes 101 are provided on the base plate 1, and the multiple mounting holes 101 are distributed in a rectangular array on the base plate 1. The XYZ adjustment slide 2 and the motor base 3 can be fixedly connected to the base plate 1 by screws at different positions of the mounting holes 101 according to the usage requirements.

[0021] A slot 601 is provided on the chip test socket 6. When the chip is tested, the chip is inserted into the slot 601. A conductive sheet is provided on the chip test socket 6 in the slot 601. After the chip is inserted, it contacts the conductive sheet and is energized. A PIN pin 602 is fixedly connected to the chip test socket 6. The PIN pin 602 is electrically connected to the conductive sheet.

[0022] The chip test socket 6 is specifically a rectangular block. After the chip test socket 6 is placed in the fixing groove 402, it is fixed by rotating the clamping bolts 5 to abut against the upper and lower ends of the chip test socket 6. The signal wheel 701 is mainly composed of a wheel body and a connecting cylinder. The wheel body and the connecting cylinder are integrated, and the connecting cylinder is detachably connected to the servo motor 7 through a screw.

[0023] The working principle of this utility model is as follows: when it is necessary to test a chip, the chip to be tested is installed in the slot 601 of the chip test socket 6, and the PIN pin 602 of the chip test socket 6 is connected to an external data acquisition device through a wire.

[0024] When it is necessary to test the sensor, the signal wheel 701 can be replaced as needed, the speed sensor can be installed in the corresponding socket 401 and fixed by the clamping bolt 5, and the speed sensor can be connected to the external data acquisition device through the wire.

[0025] During testing, after the chip under test or speed sensor is installed, its relative position to the signal wheel can be adjusted by using the XYZ adjustment slide to improve detection accuracy.
