[0002] Die castings are metal parts formed using a pressure casting process. Also known as die casting parts or pressure castings, this process uses high pressure to inject molten metal into a mold for rapid forming.

[0003] Currently, most flatness testing instruments directly inspect the flatness of die-cast parts after fixing them in place. However, because the position of the die-cast parts is not corrected and adjusted, the initial horizontal position of the die-cast parts is affected, resulting in poor flatness inspection effect and low inspection accuracy.

The vacuum pump is existing technology and can be purchased according to the usage requirements to provide suction for the storage platform 2, which is convenient for adsorbing the die-cast parts. A cylinder 204 is located in the middle of the bottom of the support platform 1. The cylinder 204 is used in conjunction with the air pump. Positioning rods 205 that penetrate to the bottom of the support platform 1 are provided at both ends and sides of the bottom of the storage platform 2, making the lifting and adjustment of the storage platform 2 more stable.

[0027] Please refer to this carefully. Figure 2 and Figure 3 The top of the support rod 102 is provided with a top plate 3. Multiple sets of mounting holes 301 are provided inside the top plate 3.

[0028] Please refer to this carefully. Figure 1 and Figure 3The support leg 101 is welded to the bottom of the support platform 1, and the bottom of the support leg 101 is provided with an anti-slip groove to provide support and make the use of the detector more stable. The support rod 102 is welded to the top of the support platform 1. The suction hole 202 is connected to the negative pressure chamber 201. The suction tube connector 203 is connected to the negative pressure chamber 201 to quickly extract the air inside the negative pressure chamber 201 and generate negative pressure. The die-casting parts can be adsorbed through the suction hole 202. The bottom of the platform 2 is provided with an installation cylinder, and the outside of the installation cylinder is provided with fastening bolts. The telescopic end of the cylinder 204 is connected to the installation cylinder. The telescopic end of the cylinder 204 is connected to the bottom of the platform 2. The cylinder 204 is connected to the support platform 1 by bolt installation. The support platform 1 is provided with a movable hole at the position of the positioning rod 205, and the positioning rod 205 passes through the movable hole to provide a limiting effect and make the up and down adjustment of the platform 2 more stable.

[0029] Please refer to this carefully. Figure 1 and Figure 2 The bottom end of the top plate 3 is welded to the support rod 102. The top plate 3 is fixedly connected to the support platform 1 through the support rod 102. The support rod 102 fixes the top plate 3 to the support platform 1. The displacement sensor 302 is provided with a mounting ring on the outside, and the mounting ring is provided with a mounting bolt that penetrates into the top plate 3. The displacement sensor 302 can be fixedly installed through the mounting bolt. The displacement sensor 302 is detachably connected to the top plate 3 through the mounting hole 301. Multiple sets of displacement sensors 302 are kept on the same plane. The mounting holes 304 inside the two sets of fixing strips 303 are arranged alternately. The infrared emitter 305 is welded to the fixing strip 303 through the mounting hole 304, so that the mounting holes 304 inside the two sets of fixing strips 303 are arranged alternately, so that the infrared rays generated by the infrared emitter 305 are woven into an infrared mesh, which facilitates the leveling of the die-casting.

[0030] Furthermore, the bottom of the support platform 1 is equipped with a control panel, and the control panel has a built-in controller, which is electrically connected to the displacement sensor 302, the infrared transmitter 305, the infrared receiver and the display screen respectively.

[0031] Working principle: First, connect the power supply to the equipment and place the die-cast part to be tested on top of the platform 2. Then, start the cylinder 204 to drive the platform 2 to rise smoothly until the upper surface of the die-cast part enters the detection area defined by the fixing strips 303 on both sides. At this time, the horizontal correction system is activated, and the infrared emitters 305 arranged alternately on both sides emit infrared beams, which are received by the infrared receivers on the opposite sides, thus forming an invisible infrared grating within the detection area.

[0032] The controller analyzes the signal status of all infrared receivers in real time. If the die-cast part is tilted, its surface will partially block the infrared beam, causing the corresponding receiver to be unable to receive a signal. The controller processes this information about the obstructed position and displays the tilt direction and magnitude of the die-cast part on the screen in a graphical interface. Following the clear instructions on the screen, the operator precisely adjusts the die-cast part by inserting thin shims at the corresponding positions on its bottom before it is firmly held in place, until the screen shows that the die-cast part has reached a level position.

[0033] After confirming that the die-casting part is level, the vacuum pump connected to the air pipe and suction pipe connector 203 starts working, extracting the air from inside the vacuum chamber 201. This causes a strong and uniform suction force to be generated on the top of the platform 2 through the suction holes 202, firmly fixing the leveled die-casting part onto the platform 2. Subsequently, the cylinder 204 is activated again, and under the guidance of the positioning rod 205, the platform 2, along with the die-casting part on it, continues to be lifted upwards until its upper surface contacts the measuring probes of all the displacement sensors 302 arrayed below the top plate 3.

[0034] Multiple displacement sensors 302 simultaneously measure the precise height data of various points on the surface of the die-cast part and transmit this data to the controller. The controller calculates the height difference of all measurement points, accurately analyzes the flatness error of the die-cast part, and displays the final test results on the screen. This process, by calibrating before testing, eliminates measurement errors caused by uneven initial placement, thus making the test results more accurate and reliable.
