a ruler frame is arranged on one side face of the vernier, and the ruler frame is provided with the measuring claw;
and the other side surface of the vernier scale, the side surface of the micro-motion frame opposite to the connecting rod and the upper end surface of the vernier frame are respectively provided with a locking screw.
Furthermore, a notch penetrating through the front end face of the micro-motion frame is formed in the front end face of the micro-motion frame.
Furthermore, a measuring ball is arranged at the front end of the measuring claw.
Further, the measuring ball and the measuring claw are fixed by welding.
The utility model has the advantages that:
the front end plane of the original measuring claw of the height gauge is improved to be spherical when in measurement, and the contact surface with a workpiece is changed into point contact, so that the height gauge can be used for more accurately measuring the range of the shape and position tolerance size of the workpiece, especially curved surfaces such as holes, arcs and the like on the basis of the original height size of the workpiece.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1, as shown in fig. 1, an improved structure for height gauge measurement includes: the height measuring device comprises a base working surface 1, a ruler body 2, a height adjusting unit and a measuring claw 3;
the ruler body 2 is arranged on the base working surface 1, the height adjusting unit is connected to the ruler body 2 in a sliding mode, and the measuring claw 3 is clamped on the height adjusting unit.
The main invention point of the scheme is that after the plane of the height gauge measuring claw is changed into the ball head, the contact mode is changed into point contact, and the limitation of the original surface contact is broken.
The front end plane of the original measuring claw (the contact surface with a workpiece during measurement) of the height gauge is improved to be spherical, and the surface contact is changed into point contact, so that the height gauge can be used for more accurately measuring the range of the shape and position tolerance size of the workpiece, particularly curved surfaces such as holes, arcs and the like on the basis of the original height size of the workpiece. For example, the position tolerance size of a circular waveguide port is measured, the measurement can be directly carried out only by subtracting the radius of the waveguide port, and the measurement error is reduced to the maximum extent, so that the measurement is more accurate, more efficient and more convenient. The cost is reduced, and meanwhile, the working efficiency is greatly improved.
