detailed description

Embodiments of the utility model will be further described below in conjunction with the accompanying drawings.

Referring to Figures 1 to 4, the base 1 is fixed with screws at both ends, and the surface has a support seat 2 with an increased friction belt knurled plate and a right-angled support column 15, and the support frame 19 is fixed with screws on the side wall of the support column. , the display 17 is installed on the support frame 19, the outer surface of the support column is the uppermost, the liner clip 16 and the spacer first 18 are fixed on the support column with screws, the strong frame 25 is clamped and fixed in the middle of the two liner clips 16, and the two liner clips are fixed with screws. The symmetrical elongated guide rail 14 is fixed on the middle position of the support column 15, and the two slide blocks 24 are respectively slidably matched with the slide grooves on both sides of the two guide rails 14.

The powerful frame 25 is hinged on the powerful rod 251 by the handle 252, and the lower end of the powerful rod is screwed to the floating joint 20 to form.

Both sides of the fixed frame 11 are respectively fixed on the two sliders 21 with screws to be connected with the slider and the guide rail as a whole, and the spacer B 22 is connected between the slider and the fixed frame, and the other side wall of the support column 15 is fixed with screws The positioning block 9 installed laterally, the fixed frame 11 and the pressure block 6 are connected with a sensor 8 . The upper and lower ends of the sensor 8 are connected with the screw holes in the middle of the fixed mount 11 and the briquetting block 6 respectively with screw rods, and are tightened with nuts to be connected into a fixed mount, a briquetting block, and a sensor that can move up and down.

The dial indicator 13 is screwed on the meter frame 10 through the meter chuck 12, and the meter frame 10 is connected to the side wall of the fixed frame 11. The lower surface of the meter frame rests on the positioning block 9 to adjust the percentage. The zero position of the table.

The fine-tuning knob 24 is installed on the middle position of the rear surface of the support column 15, and is connected with the slide block 21 for adjusting the height and locking of the slide block, the fixed frame 11, and fixing the slide block 21.

During use, 1. First loosen the fine-tuning knob 24, so that the slide block 21 connected to it can slide up and down freely, so that the fixed frame 11 and the sensor 8 connected with it can also move up and down with the slide block 21, and adjust to desired measurement location.

2. Lift the clamp 25 up to leave the measurement position, and the sensor 8 and the pressure block 6 connected to it are driven by the fixed frame 11 to move upward together, leaving a space for the measurement operation, and place the calibration piece 3' on the support base 2 , and make the calibration piece 3' close to the positioning column 4 for positioning, control it not to move, and cooperate with the pressure block 6.

3. Put down the strong frame 25, adjust the fine-tuning knob 24 to make the fixed frame reach the desired position, and then lock the fine-tuning knob 24 so that the position of the fixed frame 11 can no longer be moved, and the floating joint 20 at the lower end of the strong frame exerts pressure on the sensor 8, In order to make the operation and measurement stable, the upper and lower ball washers 7 and 5 matching the through holes are installed on the upper and lower parts of the through hole in the middle of the pressure block 6. When the value of the display 17 is 20 (the setting of the standard part and the calibration part value), at this time, if the reading value of the digital display dial indicator 13 is 0, then loosen the fine-tuning knob 24, lift up the clamp 25, and at the same time, the fixed frame and the sensor drive the pressure block 6 to move up to leave a space, and then it can be removed. The calibration part 3' is put into the test part 3 again.

4. Enter the next step of the program: put down the clamp 25 by hand, adjust the fine-tuning knob 24 to a suitable position, and lock the slider 22 to prevent the fixed frame 11 from moving again. When the reading of the display 17 is 20, the dial indicator The reading of 13 (dial indicator) is the assembly height of the angular contact bearing to be inspected, and it is qualified as the calibration part 3'.

If the value of the part to be inspected 3 is not the same as that of the calibration part 3', and exceeds the set value range, it is not a qualified product and needs to be reworked to become a qualified product, otherwise it is a waste product.

According to the above-mentioned steps, the detection and pairing of each piece 3 to be inspected are continuously carried out sequentially.
