Abstract

The utility model discloses a detector for hole-side detecting, which comprises a ruler, a cursor, a roller and a measuring head, and is characterized in that the ruler with scales and the cursor with scales are glidingly connected, the roller is arranged on the cursor, the measuring head which can move with ruler and vertical to the ruler is arranged on the ruler. While being used, the detector and the roller are leaned on the basis of a work; the ruler is stuck to the surface of the workpiece; moving the roller and the cursor, the measuring head and the ruler moves synchronously; the measuring head is inserted into the hole when gliding to the detected hole, now the data read from the detector scale is the hole-side distance of the detected hole. The utility model has the advantages of reasonable design, simple craft, easy manufacture, convenient use, quick and accurate measure, and high measurement precision.

Description

Cubing is measured on the limit, hole

(1) technical field

The utility model relates to a kind of measuring appliance, and cubing is measured on limit, particularly a kind of hole.

(2) background technology

At present, carry out the hole back gauge for the group hole on some long and narrow workpiece and measure, do not have a kind of specific purpose tool, can only measure, thereby measurement is difficult, measuring accuracy is low, has influenced surveying work efficient with traditional measuring method.

(3) summary of the invention

At the deficiencies in the prior art, the utility model provide a kind of reasonable in design, technology is simple, easy to manufacture, easy to use, measure rapidly accurately, limit, hole that measuring accuracy is high measures cubing.

Cubing is measured on limit, a kind of hole, form by blade, vernier, roller and measuring head, the vernier of the blade of band scale and band scale is slidingly connected, and roller is installed on the vernier, be equipped with on the blade with blade be synchronized with the movement, and can be on the vertical direction of blade movable measuring head.

During use, cubing body and roller are leaned against on the workpiece benchmark, blade is attached on the measured workpiece face, shifting roller and vernier, measuring head and vernier are synchronized with the movement, when measuring head slides into measured hole, promptly insert in the measured hole, at this moment the data of reading from cubing body scale promptly are the hole back gauges of measured hole.

Practical application shows, the utlity model has reasonable in design, technology is simple, easy to manufacture, easy to use, measure rapidly accurately, characteristics that measuring accuracy is high.

(4) description of drawings

Fig. 1 is a section of structure of the present utility model.

Wherein, 1, measuring head, 2, vernier, 3, blade, 4, roller.

(5) embodiment

Embodiment: structure of the present utility model as shown in Figure 1.Form by cubing body 5, blade 3, vernier 2, roller 4 and measuring head 1, the vernier 2 of the blade 3 of band scale and band scale is slidingly connected, roller 4 is installed on the vernier 2, be equipped with on the blade 3 with blade 3 be synchronized with the movement, and can be on the vertical direction of blade 3 movable measuring head 1.

Claims

1, cubing is measured on limit, a kind of hole, it is characterized in that, form that the vernier of the blade of band scale and band scale is slidingly connected by blade, vernier, roller and measuring head, roller is installed on the vernier, be equipped with on the blade with blade be synchronized with the movement, and can be on the vertical direction of blade movable measuring head.
