Abstract

The invention relates to a simple depth touch gauge. The simple depth touch gauge comprises a touch gauge through end, a measuring body, a first tensioning sleeve, a three-color handle, a second tensioning sleeve and a touch gauge stop end, wherein the measuring body is connected with the touch gauge through end in a sliding manner, and capable of sliding along the axial direction and rotating along the radial direction of the touch gauge through end, respectively; the touch gauge through end is fixed at one end of the three-color handle by the first tensioning sleeve; and the touch gauge stop end is fixed at the other end of the three-color handle by the second tensioning sleeve. Threads are arranged on each of the touch gauge through end and the touch gauge stop end; and the each of the touch gauge through end and the touch gauge stop end is smooth. The simple depth touch gauge has the advantages of being simple, compact and reasonable in structure, convenient to operate, low in manufacturing cost, high in detecting efficiency and the like. The measuring body can rotate on the through end, so that the step surface of the measuring body faces operating personnel for convenience in vision or touch judgment of the operating personnel; and moreover, the operating personnel use fingers to touch to improve detecting precision and reduce error in judgment.

Description

A kind of simple and easy degree of depth touches rule

Technical field

The present invention relates to a kind of touch rule, especially a kind of simple and easy screw thread (or smooth) degree of depth touches rule, belongs to the detection technique field of measuring.

Background technology

In prior art, the processing of internal thread or endoporus is very general operation in machining process, it mainly contains thread pitch diameter (or diameter of bore) and two detected parameters of the degree of depth internal thread, and thread pitch diameter (rough machined endoporus aperture) carries out qualitative detection with leading to/end thread profile gauge (smooth rule) usually; Screw thread (or endoporus) degree of depth common method is to carry out qualitative detection at feeler gauge go side some size grooves of processing, its accuracy of detection is low, testing result often causes error in judgement because of threaded hole or endoporus position influence operating personnel's vision, and its method is not suitable for threaded hole with the level or endoporus yet.

Summary of the invention

The object of the invention is to overcome above-mentioned weak point, provide a kind of simple and easy degree of depth to touch rule, these touch rule are measured physical efficiency and are rotated in the go side, make the cascaded surface of measuring body in the face of operating personnel, convenient operation personnel's vision or sense of touch are judged, and the finger touch with operating personnel can improve accuracy of detection, reduces error in judgement.

According to technical scheme provided by the invention, a kind of simple and easy degree of depth touches rule and comprises touch rule go side, measures body, the first expansion sleeve, three look handles, the second expansion sleeve and touch the rule not-go-end; Described measurement body is slidingly connected with touching the rule go side, can endwisely slip and radial rotating along touching the rule go side, touches the rule go side is fixed on three look handles by the first expansion sleeve a end, touches the rule not-go-end is fixed on three look handles by the second expansion sleeve the other end.

As a further improvement on the present invention, described measurement body top is provided with first disc C; Described measurement body bottom is provided with second disc B;

As a further improvement on the present invention, described measurement body is provided with second disc B, described measurement body is provided with first disc C, the axial distance of described second disc B and first disc C is A, the numerical value of described axial distance A equals the tolerance value of threaded hole (or endoporus) depth parameter, and D is the measurement face of go side.

As a further improvement on the present invention, described touch is advised on the go side and is provided with screw thread; Be provided with screw thread on the described touch rule not-go-end.

As a further improvement on the present invention, an end of described three look handles is green, and the other end of described three look handles is red end.

As a further improvement on the present invention, described touch rule go side is smooth go side; Described touch rule not-go-end is smooth not-go-end.

Compared with the prior art the present invention has the following advantages

The present invention is simple in structure, compact, reasonable, and easy to operate, cost of manufacture is low, the detection efficiency advantages of higher.The measurement physical efficiency is rotated in the go side, makes the cascaded surface of measuring body in the face of operating personnel, and convenient operation personnel's vision or sense of touch are judged, and improved accuracy of detection with operating personnel's finger touch, the minimizing error in judgement.

Description of drawings

Fig. 2 is the I partial enlarged view of Fig. 1.

Embodiment

Following the present invention is further described in connection with the embodiment in the accompanying drawing:

As shown in Figure 1 and Figure 2, the present invention mainly forms by measuring body screw thread go side 1, measurement body 2, the first expansion sleeve 3, three look handles 4, the second expansion sleeve 5 and measuring body screw thread not-go-end 6.

Measuring body 2 is slidingly connected with measurement body screw thread go side 1, can endwisely slip and radial rotating along measuring body screw thread go side 1, measure body screw thread go side 1 is fixed on three look handles 4 by the first expansion sleeve 3 green end, measure body screw thread not-go-end 6 is fixed on three look handles 4 by the second expansion sleeve 5 red end, B is for measuring second disc of body, C is for measuring first disc of body, A is B and C axial distance, and numerical value equals the tolerance value of threaded hole depth parameter, when for example the threaded hole depth parameter is 15 ± 0.2mm, then axial distance A is 0.4mm, and D is the measurement face of go side.

During detection, measure body screw thread go side 1 and measure the specification that body screw thread not-go-end 6 detects internal thread, screw thread go side 1 is screwed into measured threaded hole bottom, measure the end face of body 2 and the end contact of threaded hole, the measurement face D face that the go side is judged in operating personnel's vision or sense of touch whether at second disc B that measures body, measure between first disc C two sides of body, between B, C two sides, then the tested threaded hole degree of depth is qualified such as the D face, not between B, C two sides, then the tested threaded hole degree of depth is defective such as the D face.

Above-described embodiment is that a kind of simple and easy depth of thread touches rule, and the simple and easy smooth degree of depth touches rule need above-mentioned middle screw thread go side is changed into smooth go side, and the screw thread not-go-end changes smooth not-go-end into, and other structure is constant, and its principle of work touches the identical of rule with the simple and easy depth of thread.
