Description

Technical Field

[0001] The utility model relates to the technical field of altimeters, and more specifically, to an altimeter for workpiece detection. Background Art

[0002] A height measuring instrument, abbreviated as an altimeter or height gauge, is mainly used to measure the height of workpieces, and can also measure shape and position tolerance dimensions, such as perpendicularity and straightness. It can also be used to measure depth, groove width, internal and external diameters, high points, low points, flatness, angles, etc. At present, during the production and processing of workpieces, the processing height of the workpieces is detected to judge whether the workpieces meet the standards.

[0003] After retrieval, it is found that a Chinese patent with the authorization announcement number CN218545647U discloses an altimeter for quality inspection of hardware parts. This structure uses a horizontally adjustable device, and the supporting platform slides along the adjustable chute of the inspection table by means of adjustable sliders, and can smoothly adjust the position of the hardware parts in a straight line direction, which is convenient for multi-point detection of the same straight line direction on the surface of the hardware parts. The method of manually moving the hardware parts is not adopted, which can prevent the position of the hardware parts from shifting on the supporting platform. Moreover, during use, the limiting pressure plate is adaptively pressed against the hardware parts under the elastic force of the return spring, which can reduce the trouble of the position of the hardware parts shifting when the supporting platform is translated.

[0004] However, when this structure is actually used, it is impossible to clean the dust on the surface of the workpiece. Since a large amount of dust and debris are easily generated on the surface of the workpiece during the production and processing process, if these dust and debris are not cleaned, it is easy to affect the final measurement accuracy of the workpiece. In view of this, the present utility model proposes an altimeter for workpiece detection. Summary of the Utility Model
