At the same time, it can also improve the traceability and statistical analysis capabilities of production data, providing a more scientific basis for the company's production management.

[0022] For example, the turbocharger housing is a housing part that contains components such as the turbine shaft, turbine, and valve cover. It generally includes flow channels, air chambers, inlet / exhaust flanges, bypass valves, etc. Its structure is very complex, so it has high requirements for machining dimensions. It is usually produced by casting and processed by machining.

For example, the first measuring component 3 is on the left side of the testing platform 1, the fourth measuring component 12 and the fifth measuring component 13 are on the right side, the seventh measuring component 18 is arranged on the upper left near the first measuring component 3, the sixth measuring component 17 can be arranged behind the seventh measuring component 18, and the second measuring component 7 and the third measuring component 8 can be arranged on one side of the fourth and fifth measuring components; a cover is provided on the workbench to cover these measuring components, and a safety door that can be opened and closed is provided on the front. When the safety door is opened, the material loading and unloading operations can be carried out; a display and a control panel are also provided on the cover, and instructions or programs can be input to control the internal moving parts and measuring components and receive detected data.

[0024] The fixture includes a positioning base arranged on the detection platform, as well as components such as a pressure claw and an angular positioning component. The positioning base supports the positioning surface of the material to be detected. The pressure claw can press the material from the upper end surface of the material to be detected, and there can be multiple pressing points. The angular positioning component can limit and position the material to be detected on its outer peripheral surface (side) to keep it in a predetermined detection position so that the subsequent measurement components can measure it in sequence.

[0025] Some measuring components have only one measuring part, while some measuring components have multiple measuring parts. The multiple measuring parts basically move synchronously, and are driven by the measuring component to perform detection together, and multiple indicators at the same detection position, such as thickness and aperture, or face distance and aperture, can be detected at the same time; the seven measuring components are not independent of each other, and will be regularly matched according to the detection of materials. For example, the second measuring component and the third measuring component move up and down at the same time, but measure in steps, the fourth measuring component and the fifth measuring component also move up and down at the same time and measure in steps, the first measuring component, the second measuring component, the fourth measuring component and the sixth measuring component measure synchronously, and the third measuring component, the fourth measuring component and the seventh measuring component measure synchronously.

[0026] Further, combined with Figure 3 and Figure 4 As shown, the first measuring component 3 includes a first support 301 arranged on one side of the detection platform 1, a first horizontal slide 302 is provided on the first support 301 (a horizontal slide rail is provided, and a slider is provided on the horizontal slide rail), one end of the first horizontal slide 302 is connected to the first cylinder 303 through a connecting piece, one end of the first cylinder 303 is provided with the thickness measuring piece 304, and the thickness measuring piece 304 is a pair of measuring jaws; a first vertical plate 305 is provided on the first horizontal slide 302, one side of the first vertical plate 305 is provided with a first vertical slide 306 (a vertical slide rail is provided, and a slider is provided on the vertical slide rail), and the first vertical slide 306 is connected to the first aperture measuring piece 308 arranged vertically through a first horizontal mounting plate 307.

[0027] The thickness measuring component 304 and the first aperture measuring component 308 on the first measuring component 3 act synchronously, and both move in two directions, and can simultaneously measure the thickness of a certain characteristic part on the periphery of the material to be inspected and the aperture of the hole set thereon.

[0028] The first horizontal slide 302 drives the first cylinder 303, the first vertical plate 305 and the first horizontal mounting plate 307 to move horizontally synchronously, so that the thickness measuring piece 304 and the first aperture measuring piece 308 can move simultaneously and reach the periphery of the material; then the thickness measuring piece 304, driven by the cylinder, allows a pair of measuring jaws to clamp the measured part to measure its thickness. At the same time, the first aperture measuring piece 308, driven by the first vertical slide 306, moves downward and is inserted into the hole of the part to detect the aperture; for example, the measured thickness is 16.93±0.2mm, and the hole diameter is 9.03±0.02mm; then the first aperture measuring piece rises and returns to its original position together with the thickness measuring piece.

[0037] From the structure of the second support 4 and the third support 9, and the arrangement of the second measuring component 7 and the third measuring component 8, the fourth measuring component 12 and the fifth measuring component 13, the second measuring component 7 and the third measuring component 8 will not be detected at the same time, and the fourth measuring component 12 and the fifth measuring component 13 will not be detected at the same time.
