Embodiment Construction

[0019] The present invention will be further described below in conjunction with specific embodiments, and the advantages and characteristics of the present invention will become clearer along with the description. However, these embodiments are only exemplary and do not constitute any limitation to the scope of the present invention. Those skilled in the art should understand that the details and forms of the technical solutions of the present invention can be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements all fall within the protection scope of the present invention.

[0020] see Figure 1 to Figure 4 , the present invention relates to a measuring device for quickly measuring the runout of a shaft workpiece, comprising a measuring motion unit for adjusting a measuring contact so that the measuring contact is in contact with a shaft workpiece; a measuring pretension unit for making the measur...

Abstract

The invention relates to a measuring device for quickly measuring runout of a shaft workpiece, which is characterized by comprising: a measuring motion unit for adjusting a measuring contact to enable the measuring contact to be in contact with the shaft workpiece; a measuring and pre-tightening unit which is used for forming constant pre-tightening force between the measuring contact and the shaft workpiece; and a measurement run-out unit which is used for measuring the shaft diameter run-out of the shaft workpiece. The measuring device has the advantages that 1, the shaft diameter runout measuring device can adapt to large-range shaft diameter runout measurement without frequent adjustment and the like in a mode that the measuring motion unit is additionally arranged and the needle type air cylinder pushes the measuring rod to be lifted; and 2, by arranging the measurement pre-tightening unit, different measurement pre-tightening forces can be applied under the condition of different shaft diameters, the timeliness of motion response during measurement is ensured, and the measurement speed can be effectively improved.

Description

technical field [0001] The invention relates to a measuring device for rapidly measuring the runout of shaft workpieces, which is used for measuring the runout of shaft diameters of shaft workpieces within the range of shaft diameter difference within 20mm (the difference between the maximum shaft diameter and the minimum shaft diameter is 20mm). Background technique [0002] Existing measuring shaft runout devices can only measure a specific shaft diameter. If the shaft diameter is exceeded, manual alignment adjustment is required. The measurement steps are cumbersome and largely depend on user experience. In the existing patent CN205843528U, the shaft workpiece to be measured is placed on the V-shaped block, and the workpiece is pressed by the roller, and the user moves the measuring seat left and right through the worm gear to realize the measurement of the shaft runout. This method cannot measure shafts with large shaft diameter differences, and requires manual adjustmen...
