§≡≡≡≡  Description  ≡≡≡≡

SJ2620 measures dial indicators accurately and automatically by using Heidenhain precision linear encoder system, accurate measurement and control technology of glass-sale displacement, long-life patented precision rail, imported motorized control system, patented non-reflective light source, high-resolution CCD camera, control system with LCD touch screen, and the newest intelligent image processing technology.

 

A motor controlled by computer drives glass-scale to travel accurately, without manual adjustment by hand wheel or microdrum; All data is acquired by software automatically, without manual sampling; Scale and indication value are identified automatically by the CCD camera which completely simulates manual reading, without observed and read by operator; That Significantly reduces human labour and brainwork, as well as improves the testing speed.

 

SJ2620 is a fully automated testing machine. The operator only needs to install the dial indicator and select indicator type, division value, measuring range and other parameters in software, then the machine measures automatically after click the "Start" button, in accordance with relevant regulations. After measurement, the test record and result can be printed quickly(including data list of measuring points, error carve of forward – reverse measuring, qualification & eligibility level of indication errors, and so on). 

 

§≡≡≡≡     Features    ≡≡≡≡

1. Artificial intelligence: Do not need manual reading & recording & calculating and manual adjustment with hand wheel or microdrum.

    (1) Scale and indication value are identified automatically by the CCD camera which completely simulates manual reading, without observed, read and recorded by operator

   (2) Function of automatic zeroing without manual zeroing before testing;

   (3) A motor controlled by computer drives measuring spindle to arrive measuring point accurately, without manual adjustment by hand wheel or microdrum

   (4) Powerful software automatically processes and qualifies the measured data, finally generates test result, additionally all test records can be queried, displayed, saved, printed.

 

2. Special light source:

   (1) Patented no-reflective light source(Patent No.: ZL200620056214.1) 

   (2) If the surface of dial indicator is convex, the no-reflective light source is necessary to assure reliability of test data.

 

3. New patented slider:

National utility model patent(Patent No.: ZL201220239454.0)

Eliminate gap in forward – reverse measuring by reducing the wear between the slider and the guide rail;

High repeatability: significantly improve lifespan of the slider and guide rail.

 

4. Humanized design:

With Humanized design for both machine and software, the operator can be trained to use it in a short time. Operation of software with user-friendly UI is extremely simple. Particularly the system can identify pointer on dial indicator and acquire the indication value accurately even if the dial indicator is not in the right center of camera, so the dial indicator can be installed fast, and that simplifies the operating procedure and save operating time.

 

5. Large-capacity database

With built-in large-capacity storage space for database, the system can record and save all test records automatically.

 

6. Powerful print

Output 3 formal and nice report formats(curve, sheet or error value). Test data can be saved automatically, particularly a number of test results can be printed at a time, which saves operating time.
