Marble roughness testing platform

summary:

The roughness meter platform is one of the main accessories of portable roughness measuring instruments, suitable for various domestic handheld roughness metersTR200、TR210、NDT150、 By providing it with a high-precision measurement platform and column lifting system, it is easy to adjust the instrument, which greatly reduces the difficulty of instrument operation, especially when measuring high-precision parts, the effect will be more obvious. This product is also suitable for users who use roughness measuring instruments from other manufacturers (including foreign manufacturers), but a dedicated connecting component needs to be customized. Of course, special users for other purposes cannot be excluded. For specialized sensors, this set of accessories is necessary for complex and precise adjustments.

Name of each section:

working principle:

The operator drives the screw nut system to move by rotating the lifting handwheel. The nut is connected to the carriage, and the carriage is connected to the instrument, thereby driving the instrument to move up and down along the precision dovetail guide rail. Due to the special design of eliminating gaps in the screw nut system, the lifting return difference is adjusted to be very small, therefore, the lifting adjustment accuracy of this system is very high. And it adopts centering and thrust bearings to improve the smoothness of rotation.

Technical parameters:

Screw rod lifting, set on the platformV-shaped groove is used to measure workpieces with smaller shapes, which can improve measurement accuracy.

Lifting height:300±1mm；

Lift return error: not greater than the rotation of the handwheel1/6 circle;

Flatness of measurement platform:Grade 00 (plane tolerance value 3 μ m);

Measurement platform size:400*250*80mm。

Operation steps:

According to the instructions of the roughness meter, first install the sensor onto the instrument, then install the platform connection board onto the mainframe of the roughness meter, and finally install the instrument onto the slide of the column, locking it securely.

Place the workpiece on the platform (orV block), and then adjust the lifting handwheel to make the sensor close to the workpiece. When the sensor is about to approach the workpiece, the sensor must slow down its lowering speed. When the sensor contacts the workpiece, carefully observe the position of the stylus. When the stylus is near the zero position, the measurement can be made. When measuring cylindrical workpieces axially, the workpiece can be placed on a randomly configured V-shaped block, and the centerline of the V-shaped block is in the same vertical plane as the contact pin of the sensor (which has been adjusted at the factory), that is, the busbar measured by the sensor after contacting the workpiece is the highest point of the cylindrical workpiece. Before adjusting the lifting handwheel, first loosen the locking handwheel of the carriage; When measuring high-precision parts, the column locking handwheel can be tightened to make the measurement more stable and accurate. Regularly clean and prevent rust; Do not forcefully move the slide sideways; When moving, do not directly move the column. Instead, hold the platform and move it to prevent the column from loosening and positioning errors.

Standard configuration;

Note: Various customization requirements can be provided to adapt to the use of roughness measuring instruments of various manufacturers and models.
