Overview of YY1045-2021 Dental Phone Locking Torque Tester:

1. Basic Overview

The YY1045-2021 dental mobile phone stalling torque tester is an important device used to accurately evaluate the torque performance of dental mobile phones in a stalling state. In dental treatment, dental phones are indispensable high-speed cutting tools, and their performance stability directly affects the safety and efficiency of treatment. This tester can ensure that dental phones meet relevant standards, avoiding equipment damage or patient treatment risks caused by abnormal torque.

2. Technical Specifications

Display Screen and Control

Adopting a 7-inch K600+core/dot matrix 65 color 800 * 480 resolution touch screen display, the operation interface can be switched between Chinese, English or Chinese English, making it convenient for different users to use. At the same time, it has a PLC control system that can dynamically display the loading force value.

3. Control and Collection

Adopting digital closed-loop control, the AD acquisition speed is 500KHz, with an internal code of 1 million (some products have an internal code of 500000); It is also equipped with a high-precision clock chip with power-off storage function. In addition, there is an overload alarm shutdown protection function to ensure the safety of equipment and use.

Torque and time setting

The torque setting range is 0-0.01N. m, with an error not exceeding ± 0.0005N. m, using a contact torque sensor. The test time can be set arbitrarily within 1 to 99 seconds, with an error not exceeding ± 1 second.

4. Printing method

Print the average data of 10 tests and their total average and deviation values.

Other parameters

Net weight of 10.5kg, external dimensions of 400 × 290 × 275 (mm), power requirement of AC90V-240V/50Hz, input mode supporting Chinese and English input, some products support remote control and multi-level permission management.

5. Functional Features

automated operation

The menu on the LCD screen is controlled by a touch screen (some products can also use a keyboard), which can automatically load pressure, record data, display tension and peak force data in real time, output data reports automatically, and print ten test reports onboard.

6. Standard execution

Implement the provisions of 7.16 in YY1045-2021 standard to ensure the standardization and reliability of the testing.

7. Instructions for use

Pre-test preparation

Confirm that the power connection of the tester is normal, and check that the torque sensor and fixture are not damaged.

Check if the air/power interface of the dental mobile phone matches the tester. If the pneumatic mobile phone needs to be connected to a stable air source, adjust the air pressure to the manufacturer's calibration value (usually 0.2-0.25MPa).

Perform zero calibration on the torque tester according to the instructions, and if necessary, use a standard torque wrench to verify accuracy. Fix the head of the phone onto the fixture of the tester, ensuring clamping and alignment of the axis to avoid eccentric forces affecting the results.

8. Testing steps

Set parameters: Select the measurement mode (such as peak torque, dynamic torque) on the tester interface, set the sampling frequency and testing duration (usually 3-5 seconds for stall testing to avoid overheating).

Start test: Press the start button on the tester to trigger the operation of the dental phone (the pneumatic phone requires stepping on the foot switch). The tester will automatically apply resistance to simulate a locked state and record real-time torque values.

Data recording: Observe the peak torque value (in N · cm or mN · m) to ensure that it does not exceed the nominal value of the mobile phone (such as high-speed mobile phones, which are usually 0-0.01N. m), save the data, and some devices can generate curve graphs for analysis.

Repeated testing: It is recommended to repeat 3-5 times and take the average to avoid accidental errors.

Operation after testing

Turn off the device: First stop the dental phone, then turn off the power/air source of the tester, disassemble the phone, and check for any abnormal heating or wear.

Data analysis: If the torque does not meet the standard, it may indicate internal bearing loss or transmission failure of the phone.

9. Application Fields

production process

In the production process of dental mobile phones, this tester is the core tool for quality control, ensuring that each phone meets the YY1045-2021 standard requirements and enhancing the product's market competitiveness.
