Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a multifunctional precision testing device. Background Technology

[0002] There are many types of testing equipment. Factories commonly use a variety of testing equipment, including measuring instruments such as calipers, balances, and marking machines.

In the packaging process, common equipment includes packaging material testing instruments, metal testing equipment, non-metal testing equipment, and non-destructive testing equipment.

[0003] Currently, conventional precision testing equipment still has many shortcomings: 1. Extremely low testing efficiency: It relies on manual handling of the parts to be tested, adjustment of the placement angle, and positioning calibration. Single-part testing is time-consuming and cannot match the continuous production testing rhythm of multiple sets of molds for batch injection molded parts in factories; 2. High operating threshold: Professional personnel are required to master the equipment operation logic and parameter debugging skills. The personnel training cycle is long, and the proficiency of operation directly affects the testing accuracy, resulting in high labor costs; 3. Limited and singular functions: It focuses on the detection of geometric parameters such as hole position and size. It has weak ability to identify appearance defects such as burrs and minor scratches on the surface of injection molded parts. It needs to be combined with other equipment for secondary testing, which is cumbersome; 4. Poor adaptability: For injection molded parts of different specifications, it is necessary to repeatedly adjust the tooling fixtures and testing parameters. Switching is time-consuming and cannot quickly respond to the testing needs of multi-category production; 5. Large human intervention error: During the testing process, manual placement and data reading are easily affected by human operation deviations, resulting in poor testing consistency and a high rate of missed detection and misjudgment of defective products.

[0004] Therefore, those skilled in the art have provided a multifunctional precision testing device to solve the problems mentioned in the background art. Utility Model Content
