In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a detection apparatus for be used for quartzy ceramic crucible outer bottom roughness, is provided with fixed baseplate including the horizontal square pipe that is used for the device main part, and horizontal square intraductal middle part is provided with fixed baseplate, is provided with the display amesdial of fixed number on the fixed baseplate, and fixed baseplate's both sides symmetry respectively are provided with the removal base, is provided with first digital display amesdial and second digital display amesdial on the removal base respectively, and the both ends of horizontal square pipe are provided with the supporting legs respectively.

Furthermore, the flatness of the horizontal square tube is less than or equal to 0.1mm, and the length is 1.2-1.6m.

Furthermore, two sides of the interior of the horizontal square tube are respectively provided with a sliding groove track, the moving base is connected in the sliding groove tracks in a sliding mode, and the length of each sliding groove track is 30-50cm.

Furthermore, the horizontal two sides of the end part of the horizontal square tube are respectively provided with a guide rail, and the supporting legs are connected on the guide rails in a sliding manner.

Furthermore, the height between the bottom of the supporting leg and the bottom of the horizontal square tube is 3-10mm.

Furthermore, a level ruler is arranged on the horizontal square tube.

Compared with the prior art, the utility model the advantage lie in: the utility model discloses an improvement level bar to but install the portable digital display percentage table on the different positions of level bar, through the numerical value of the biggest and minimum point of record, calculate and obtain the bottom roughness.

The utility model has more accurate detection data and less influence of operators on the detection data; the sensed data may be subject to process control analysis.
