Problems solved by technology

[0009] Conventionally, when replacing a measuring arm, first, a stylus that must measure the tip of the arm is placed on a measuring device for measuring force such as an electronic balance, and the measuring force adjustment mechanism is adjusted in this state so that the value of the measuring device is 0, so there are problems such as poor usability and poor work efficiency

Embodiment Construction

[0054] Description of surface texture measuring instrument (refer to Figure 1 to Figure 8 )

[0055] Such as figure 1 As shown, the surface texture measuring instrument of this embodiment has: a base 1; a workbench 10, which is placed on the base 1 and an object to be measured is placed on the upper surface; a stylus displacement detection part 20, which has a stylus 26A, 26B in contact with the surface of the object to be measured; and a relative movement mechanism 40 for relatively moving the stylus displacement detection part 20 and the table 10 .

[0056] The relative movement mechanism 40 has: a Y-axis driving mechanism 41, which is arranged between the base 1 and the workbench 10, and is used to move the workbench 10 to one direction (Y-axis direction) in the horizontal direction; a column 42, which is erected On the upper surface of the base 1; Z slider 43, which is arranged on the column 42 in a manner capable of moving up and down (Z-axis direction); Z-axis drivi...

Abstract

The invention provides a surface texture measuring instrument. In the surface texture measuring instrument, a measurement arm (24) includes: a first measurement arm (24A) that is supported by a bracket (22) around a support shaft (23) movably in a circular movement in a casing (28); and a second measurement arm (24B) having styluses (26A, 26B) that are attachably and detachably provided to an end of the first measurement arm (24A) via an attachment-detachment mechanism (25), the attachment-detachment mechanism (25) being arranged in the casing. A displacement detector (27) includes: a scale (27A) provided to the measurement arm; and a detection head provided to the bracket (22) to face the scale. A detecting surface of the scale is on an axis of the measurement arm and on a plane of the circular movement of the measurement arm.

Description

technical field [0001] The invention relates to a surface texture measuring instrument. Specifically, it relates to a surface texture measuring instrument capable of replacing a measuring arm having a stylus for contacting the surface of a measured object. Background technique [0002] There is known a surface texture measuring instrument that moves a stylus along the surface of the object to be measured while the stylus is in contact with the surface of the object to be measured. Displacement due to surface shape and surface roughness (displacement in a direction perpendicular to the direction of movement of the stylus), and the surface shape, surface roughness, and other surface properties of the object to be measured are measured based on the displacement of the stylus. [0003] Among the surface texture measuring instruments, there have been proposed surface texture measuring instruments in which styli (measuring arms) of various shapes are prepared in advance in order ...
