[0022] The following is combined with Figure 1 To Attachment Figure 7 The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0023] A universal parts inner diameter detection and positioning device comprises a base plate 1, a limit frame group 2, a telescopic push rod 3, a measuring resisting group 4, a push rod limit plate 7 and a spring 8. A limit frame group 2 is arranged above the base plate 1, push rod limit plates 7 are fixed on both sides of the limit frame group 2, and the push rod limit plates 7 are clamped with the telescopic push rod 3; a measuring resisting group 4 is arranged on the limit frame group 2; the limit frame group 2 comprises a first limit frame 21 and a second limit frame 22, and the measuring resisting group 4 comprises a fixed resisting block 41 and a movable resisting block 42; the fixed resisting block 4 1 is fixed at the inner end of the first limit frame 21, and the mobile stopper 42 is clamped inside the second limit frame 22; a spring 8 is fixed at the bottom of the mobile stopper 42, and the other end of the spring 8 is fixedly connected to the second limit frame 22; the distance between the fixed stopper 41 and the mobile stopper 42 matches the push plate of the telescopic push rod 3; the mobile stopper 42 is provided with an arc-shaped lead-in angle to facilitate the placement of the measured object. When the measured object is placed, the measured object pushes the mobile stopper 42 and squeezes the spring 8 to place the measured object. A position sensor 5 is installed on the fixed stopper 41, and the measuring plane of the position sensor 5 is flush with the deepest point of the fixed stopper 41; a display screen 9 is provided on the first limit frame 21, and the display screen 9 is electrically connected to the position sensor 5. A position measuring block 6 is installed on the movable resisting block 42, and the measured plane of the position measuring block 6 is flush with the deepest point of the recessed movable resisting block 42; a first dividing plate 10 and a second dividing plate 11 are movably installed on both sides of the base plate 1, one end of a first telescopic rod 13 is hinged on the middle fixed block 12, and the other end is hinged on the first dividing plate 10; one end of a second telescopic rod 14 is hinged on the middle fixed block 12, and the other end is hinged on the second dividing plate 11; an middle fixed block 12 is fixedly installed at the bottom of the base plate 1, and the first telescopic rod 13 and the second telescopic rod 14 are hinged on both sides of the middle fixed block 12 respectively; sliding support rods 15 are fixedly installed at the four corners of the base plate 1, and support columns 16 are fixedly connected to the four corners of the limit frame group 2.

[0024] The position sensor 5 identifies the position of the measured object and transmits it to the display screen 9. If the displayed value does not meet the standard of the measured object, the telescopic push rod 3 on the side of the second dividing plate 11 extends to push the measured object, and at the same time, the second telescopic rod 14 retracts to drive the first dividing plate 10 to move downward, so that the measured object is pushed down; if the displayed value meets the standard of the measured object, the telescopic push rod 3 on the side of the first dividing plate 10 extends to push the measured object, and at the same time, the first telescopic rod 13 retracts to drive the second dividing plate 11 to move downward, so that the measured object is pushed down.

If other positions of the same part need to be measured, the sliding support rod 15 is controlled to move downward or upward to adjust the measured position of the part. Different positions of the same part can be measured without the need to separately match a set of special detection devices; the sliding support rod 15 is parallel to the support column 16, and the sliding support rod 15 and the support column 16 are connected together through the base sleeve 17.

[0026] How it works

[0027] The measured piece is placed between the fixed stop block 41 and the movable stop block 42. The movable stop block 42 is provided with an arc-shaped lead-in angle to facilitate the placement of the measured piece. When the measured piece is placed, the measured piece pushes the movable stop block 42 and squeezes the spring 8 to place the measured piece. After the measured piece is placed, the position sensor 5 identifies the position of the measured piece and transmits it to the display screen 9. If the displayed value does not meet the standard of the measured piece, the telescopic push rod 3 on the side of the second material dividing plate 11 extends to push the measured piece, and at the same time, the second telescopic rod 14 retracts to drive the first material dividing plate 10 to move downward to push the measured piece down; if the displayed value meets the standard of the measured piece, the telescopic push rod 3 on the side of the first material dividing plate 10 extends to push the measured piece, and at the same time, the first telescopic rod 13 retracts to drive the second material dividing plate 11 to move downward to push the measured piece down. If other positions of the same part are to be measured, the sliding support rod 15 is manipulated to move downward or upward to adjust the measured position of the part.
