[0002] The automobile dynamic balance plate is a kind of accessory used to correct the wheel balance. It corrects the wheel balance by adding weights on the inner or outer side of the wheel rim, so as to reduce the vibration of the vehicle when driving at high speed and the vibration of the steering wheel. The dynamic balance plate is one of the important parts of the automobile. During the production process of the dynamic balance plate, it is necessary to detect the dynamic balance plate. Therefore, a gauge is needed. However, the existing gauges still have the following deficiencies:

Push the heightening movable block 503 to make the heightening movable block 503 move backward along the standard linear guide rail 501. Then, drive the lever dial indicator 505 to move backward through the dial indicator bracket 504. Gently lift the lever dial indicator 505 and perform zeroing calibration on the zeroing block 3 with the dial indicator probe 506 to ensure the accuracy of the detection data. After that, take out the zeroing block 3, place the detection product on the detection seat 508 and fix it. Then, perform height detection again with the dial indicator probe 506. If the reading of the lever dial indicator 505 is within the tolerance range, it is qualified; otherwise, it is unqualified.

[0024] Please refer to Figure 1 and Figure 3, a dial gauge bracket 504 is installed at the rear end of the upper surface of the raised movable block 503, and a lever dial gauge 505 is arranged on the upper side of the dial gauge bracket 504. The rear end of the lever dial gauge 505 is rotatably connected with a dial gauge probe 506. A thrust ball bearing 507 is arranged on the inner side of the rear end of the fixed base plate 1, and a detection seat 508 is arranged on the upper side of the thrust ball bearing 507. A detection pin 509 is installed at the upper end inside the detection seat 508, and a guiding pin head 510 is arranged on the upper surface of the detection pin 509. Bending handles 6 are installed on the front and rear surfaces of the fixed base plate 1, and two groups of bending handles 6 are symmetrically arranged.

A support vertical plate 802 is installed on the upper surface of the front end of the support frame body 801, and a support horizontal plate 803 is arranged on the upper surface of the support vertical plate 802. The rear surface of the support horizontal plate 803 is connected to the upper front surface of the support frame body 801, and an electric push rod 804 is installed on the upper surface of the front end of the support horizontal plate 803.

[0025] The specific operation is as follows. When in use, after fixing the product to be detected on the detection seat 508, start the electric push rod 804 to drive the fixed frame body 805 to move downward, so that the fixed frame body 805 drives the two limiting members 809 to move downward to both sides of the product. Start the servo motor 806 to drive the bidirectional lead screw 807 to rotate, thereby driving the connecting ring 808 to move along the surface of the bidirectional lead screw 807. At the same time, the limiting member 809 slides along the surface of the limiting scale 811 until the two limiting members 809 are stuck at both outer ends of the product, and then the outer diameter of the product can be measured through the sensor 810. After that, through the electric push rod 804 and the servo motor 806, the limiting members 809 are placed inside the product, and the two limiting members 809 are moved towards both ends until the two limiting members 809 are in contact with the inner surface of the product, and then the inner diameter of the product can be measured through the sensor 810.

Push the height-adjusting movable block 503 to move the height-adjusting movable block 503 backward along the standard linear guide rail 501. Then, drive the lever dial indicator 505 to move backward through the dial indicator support 504. Gently lift the lever dial indicator 505 and perform zeroing correction on the zeroing block 3 with the dial indicator probe 506 to ensure the accuracy of the detection data. After that, take out the zeroing block 3, place the product to be detected on the inspection seat 508 and fix it. Again, perform height detection with the dial indicator probe 506. If the reading of the lever dial indicator 505 is within the tolerance range, it is qualified; otherwise, it is unqualified. Subsequently, after fixing the product to be detected on the inspection seat 508, start the electric push rod 804 to drive the fixed frame 805 to move downward, so that the fixed frame 805 drives the two sets of limit parts 809 to move downward to both sides of the product. Start the servo motor 806 to drive the bidirectional lead screw 807 to rotate, and then drive the connecting ring 808 to move along the surface of the bidirectional lead screw 807. At the same time, the limit parts 809 slide along the surface of the limit scale 811 until the two sets of limit parts 809 are stuck at both outer ends of the product, and then the outer diameter of the product can be measured by the sensor 810. After that, through the electric push rod 804 and the servo motor 806, make the limit parts 809 located inside the product and move the two sets of limit parts 809 to both ends until the two sets of limit parts 809 are in contact with the inner surface of the product, and then the inner diameter of the product can be measured by the sensor 810.
