Technical Field

[0001] This utility model belongs to the technical field, specifically relating to a tooling and measuring equipment for measuring the flatness of die-casting end plates. Background Technology

[0002] During the production of die-cast end plates, it is necessary to conduct 100% flatness inspection of the product according to the product drawings.

[0003] Currently, there are two common methods for inspecting the flatness of die-cast end plates: one is to use a 2.5D coordinate measuring machine or a three-coordinate measuring machine for measurement; the other is to place the die-cast end plate on a marble surface and manually inspect it with a feeler gauge.

[0004] However, using Method 1 to measure the flatness of die-cast end plates cannot achieve 100% accuracy; it can only perform sampling and will consume a large amount of measurement equipment resources. Using Method 2 to measure the flatness of die-cast end plates relies entirely on human measurement and subjective judgment, which may lead to misjudgment due to human fatigue from long hours of work. In addition, the manual inspection time for the flatness of each die-cast end plate is about 12 seconds, which is time-consuming. Utility Model Content

[0047] In this embodiment, the guide baffle 23 and the limiting baffle 24 are arranged perpendicularly to each other, which can position the product under test 100 placed on the base plate 22, that is, the two sides of the product under test 100 can be pressed against the guide baffle 23 and the limiting baffle 24 respectively; after the product under test 100 is placed in place, the pressing device 25 can press the product under test 100 onto the base plate 22; finally, the Z-axis coordinate data of the product under test 100 at the corresponding position is collected by the contact displacement sensor 26, thereby obtaining its flatness.

[0048] Furthermore, to detect whether the product under test 100 is placed in the correct position, proximity sensors 27 are provided at the connected ends of the guide baffle 23 and the limiting baffle 24. For example, if the product under test 100 is placed in the correct position, the indicator lights on both proximity sensors 27 will light up; if the indicator lights do not light up, it indicates that the product is not placed in the correct position.

Then, a fastener is screwed into the locking hole 2223, thereby tightening the blocks on both sides of the notch 2222 to fix the contact displacement sensor 26 in the mounting hole 2221. Then, the upper end of the contact displacement sensor 26 is inserted into the through hole 221, and a fastener is passed through the fixing hole 2224 and screwed into the corresponding fixing hole on the base plate 22, thereby fixing the fixing block 222 on the bottom surface of the base plate 22, thus completing the installation of the contact displacement sensor 26.

[0054] In this embodiment, the number and position of the contact displacement sensors 26 can be adjusted as needed. The detachable mounting method of the fixing block 222 also facilitates the adjustment of the model and length of the contact displacement sensors 26.
