The manual three-coordinate measuring instrument is also a type of coordinate measuring instrument. Its main operation process is that the user holds the main shaft with his hand and moves him back and forth along the X, Y, and Z axes. When measuring, it is necessary to pay attention to the measurement pressure between the probe and the workpiece, the acceleration of the probe or the bending of the shaft when the probe moves, which will lead to deviations in the measurement results.
The manual three-coordinate measuring instrument adopts a bridge structure, its rigid structure is better, the weight of the fixed worktable is relatively light, and it adopts a fully enclosed frame-type movement. Has good sports performance. With perfect mass-to-rigidity ratio, optical imaging system can be optionally selected to meet various inspection needs of various workshop sites.
1. First of all, you need to open the total air source and computer to ensure that the air pressure reaches the required level of the machine. Open the measuring software, and perform zeroing of the measuring machine, so that the machine automatically moves to the zero position.
2. After installing the probe stylus, perform stylus calibration. After selecting the relevant parameters, select the standard ball to calibrate the stylus. In the test results, the measured diameter should be smaller than the theoretical diameter.
3. Then establish a coordinate system: part alignment, rotation axis and setting origin. There are many ways to establish a coordinate system, the more common is the way of surface line points.
4. Then make dots and construct measurement elements. The PC-DMIS menu visually displays the subdivision measurement elements under the point, line and surface. Press the menu selection operation to complete the element construction.
5. After the construction is completed, the measurement and evaluation can be started, and whether the measurement results meet the requirements can be judged according to the drawings. The final output report, which PC-DMIS supports multiple formats of report output.
6. After the three-coordinate use is explained, the Z state should be raised and the angle A of the probe should be rotated to a 90° direction and moved to a safe position. Then, close the software, turn off the power supply, and turn off the gas source. After completing the work, clean the work surface and keep it clean. In the follow-up, you need to refer to the manual to maintain the measuring machine.
First, turn on the air conditioner before starting the machine, keep the measured temperature at about 20 degrees Celsius, and the humidity should be less than or equal to 2% RH, then turn on and turn on the freeze dryer, and then turn on the compressor air switch to see if the air pressure is 0.45Mpa , If it is not within this range, check the air source, then clean the guide rails, it is best to use a silk cloth dipped in alcohol to clean, then clean all other objects, and scrub the countertop with anhydrous alcohol.
Second, turn on the power, turn on the computer, start the software icon on the desktop, then turn on the servo switch, return the measuring instrument to zero, and then start the measuring machine calibration.
Third, calibrate the measuring machine according to the operation steps, so that he can enter the normal working state, and save the working data of each day. After a day's work, close the software, then turn off the computer, and turn off the power supply.
1. Daily maintenance
When starting the machine for the first time every day, use a clean cotton (silk) cloth or cotton wool to dip a small amount (it is advisable not to flow downward when scrubbing the facade of the guide rail) ethanol alcohol or 120# aviation gasoline to wipe the guide rail surface (must be used when cleaning the guide rail surface). clean gasoline);
Check whether the system air pressure is normal;
Check the guide rails of each axis for new scratches;
Check whether the machine is running abnormally;
2. Weekly maintenance
In order to avoid the clogging of the precision filter and affect the normal operation of the measuring machine, the filters at all levels should be checked every week and the accumulated water should be drained. Check the Z-axis balance wire rope and its connections for damage.
3. Monthly maintenance
Check the filter element of the triple filter for contamination. If serious pollution is found, the filter element needs to be cleaned or replaced, and if necessary, additional air filter and freeze dryer are required to improve the air quality.
4. Quarterly maintenance
Check for contamination, loose or damaged wiring within the control system.
Check the air system and piping for ruptures.
Check whether the grating scale and reading head are too dirty (refer to the original manual for detailed operation).
