The length of the component can be measured by the first sensor assembly 35 cooperating with the first length clamping assembly 34, and the slide on the first length clamping assembly 34 is connected to a counterweight block 527 by a rope. The counterweight block 527 drives the first length clamping assembly 34 to move until it encounters material obstruction, and the first length clamping assembly 34 cannot move and stops; a distance sensor is installed on the frame 1 below the counterweight block 527 of the first length clamping assembly 34, and the length of the component can be measured again by the distance sensor, thereby ensuring the accuracy of the measurement; the length measuring jig 33 is installed with a first guide wheel 36 for supporting the sliding of the rope.

[0043] The first sensor component 35 is a distance sensor component, and its measurement principle is: when the industrial component is clamped, the distance from the first sensor component 35 to the limit block at one end of the length measuring fixture 33 away from the first length clamping component 34 is a fixed value, and the distance from the first sensor component 35 to the end of the first length clamping component 34 can be measured, and then the length of the industrial component can be obtained.

The parts are clamped in the width measuring jig 43; a second sensor assembly 45 cooperating with the second width clamping assembly 44 is installed on the side of the width measuring jig 43 away from the second length clamping assembly 42. The width of the parts can be measured by the second sensor assembly 45 cooperating with the second width clamping assembly 44, and the slide on the second width clamping assembly 44 is connected to the counterweight block 527 by a rope. A distance sensor is installed on the frame below the counterweight block 527 of the width measuring mechanism 4. The width of the parts can be further measured by the distance sensor to further ensure the accuracy of the measurement of the width of the parts. The width measuring jig 43 is installed with a second guide wheel 46 cooperating with the rope.

[0047] The sensor in the second sensor assembly 45 is a distance sensor assembly, and its measurement principle is that when the industrial component is clamped, the distance from the second sensor assembly 45 to the limit block on the width measuring jig 43 away from the end of the second width clamping assembly 44 is a fixed value, and the distance from the second sensor assembly 45 to the end surface of the slide of the second width clamping assembly 44 can be measured, and then the width of the industrial component can be obtained.

[0048] The principle of measuring by the distance sensor below the counterweight 527 is the same as that of this part in the length measuring mechanism 3.

[0049] like Figure 6-8 The middle thickness measuring mechanism 5 comprises: a first fixture switching component 51 and a middle thickness measuring component 52; two middle thickness measuring components 52 are arranged on one side of the first fixture switching component 51;

[0050] The first fixture switching assembly 51 includes a first base 511, a first screw module 512, a middle thickness fixture 513, and a thickness clamping assembly 514; the bottom of the first base 511 is fixedly installed on the frame 1, and two middle thickness fixtures 513 are slidably installed on the top of the first base 511, and the middle thickness fixture 513 is used to place the industrial parts to be tested; the top of the first base 511 is installed with a first screw module 512 that drives the two middle thickness fixtures 513 to move back and forth, and the middle thickness fixture 513 can be driven to move back and forth by the first screw module 512, thereby realizing The parts are transported to the middle thickness measurement position (i.e., below the lifting seat 523), and a thickness clamping assembly 514 is slidably installed on one side of the middle thickness fixture 513. The gear lever on the thickness clamping assembly 514 and the limit block on the middle thickness fixture 513 work together to clamp the parts to be measured; a plurality of photoelectric sensors are installed on one side of the first base 511, and a sensing plate cooperating with the photoelectric sensor is installed on the middle thickness fixture 513. The position of the middle thickness fixture 513 can be sensed by the photoelectric sensor, and then the middle thickness fixture 513 stops moving when it slides into place;

[0051] The thickness clamping assembly 514 is a structure in which a cylinder drives a stop rod.

When the seat 523 moves to the maximum stroke, buffering is performed; a third sensor assembly 524 is installed on the side of the lifting seat 523, and the third sensor assembly 524 is used to measure the middle thickness of the parts; the lifting seat 523 drives the third sensor assembly 524 to move, and the lifting seat 523 descends. When the lifting seat 523 contacts the industrial parts to be tested, the lifting seat 523 cannot descend, so the third sensor assembly 524 detects the distance between the lower surface of the lifting seat 523 and the upper surface of the middle thickness fixture 513, which is the thickness detection. The third guide wheel 526 is rotatably installed at the top of the first support frame 521, and the lifting seat 523 is connected to the counterweight block 527 through a rope, and the rope is supported by the third guide wheel 526. A distance sensor is installed below the counterweight block 527, and the middle thickness of the parts can be further measured through the distance sensor.

[0054] The measuring principle of the middle thickness measuring mechanism 5 is as follows: the sensor in the third sensor assembly 524 is a distance sensor, which is used to detect the distance between the lower surface of the lifting seat 523 and the upper surface of the middle thickness jig 513. A distance sensor is installed below the counterweight block 527 to measure the distance of the lifting seat 523 descending. The difference between the distance before the lifting seat 523 descends and the distance after the lifting seat 523 descends is the middle thickness of the component.

A linear guide rail 624 is installed on the outer side of the first lifting plate 623, and the lower pressing plate 625 is installed on the linear guide rail 624, so that the lower pressing plate 625 can slide relative to the first lifting plate 623. When measuring the end thickness, the lower surface of the lower pressing plate 625 contacts the component to be measured; a lifting rod 626 is fixedly mounted on one side of the lower pressing plate 625; a fourth sensor assembly 627 cooperating with the lifting rod 626 is installed on the second support frame 621, and the thickness of the end of the component can be measured by the fourth sensor assembly 627.

[0060] The measuring principle of the end thickness measuring mechanism 6 is as follows: the sensor in the fourth sensor assembly 627 is a distance sensor, the distance A between the fourth sensor assembly 627 and the surface of the end thickness jig 615 is a constant, the fourth sensor assembly 627 measures the distance B between the fourth sensor assembly 627 and the lower surface of the lifting rod 626, because the distance C between the lower surface of the lifting rod 626 and the lower surface of the lower pressure plate 625 is fixed, and then the thickness of the end of the component is obtained (A+ B-C).
