Embodiment
In order to solve current survey instrument efficiency and the lower problem of accuracy when measuring trapezoidal inwall lateral dimension, present embodiment provides a kind of trapezoidal workpiece inwall lateral dimension measurement mechanism 100.Below in conjunction with specific embodiment, trapezoidal workpiece inwall lateral dimension measurement mechanism 100 is specifically described.
Please refer to Fig. 1 and Fig. 2, the trapezoidal workpiece inwall lateral dimension measurement mechanism 100 that present embodiment provides, comprise main scale 110, be arranged on pit gauge 120, sway brace 130 and the cushion block 140 on main scale 110 respectively.Pit gauge 120 and sway brace 130 are connected to the two ends of main scale 110, and cushion block 130 is arranged between pit gauge 120 and sway brace 130.For the ease of understanding, marked out measured trapezoidal workpiece 200 in Fig. 2.
In the present embodiment, pit gauge 120 comprises telescopic surveyingpin 122 and digital indicator 124.According to the needs of actual measurement, the length that operating personnel can control survey pin 122 stretch out.Simultaneously, digital indicator 124 can demonstrate the length that surveyingpin 122 stretches out.In the present embodiment, pit gauge 120 can be vernier depth gauge.
One end of sway brace 130 is fixed on main scale 110, and the other end of sway brace 130 is angular shape 132.The effect of angular shape 132 is mainly that an end of trapezoidal workpiece inwall lateral dimension measurement mechanism 100 is resisted against on measured trapezoidal workpiece 200 inwalls fully.Because if there is no sway brace 130, and directly allow main scale 110 lean against on measured trapezoidal workpiece 200 inwalls, the side end face of main scale 110 and measured trapezoidal workpiece 200 inwalls can not be fastened togather fully so, and main scale 110 also can't accurately measure size accurately like this.In the present embodiment, in this angular shape 132, the angle of wedge angle is 35～55 degree.Here angular shape 132 also can be substituted by the duck-beak type flat structure, in order to guarantee this duck-beak type flat structure, can play and the much the same effect of angular shape 132, and the thickness of duck-beak type flat structure should be less than 1 millimeter.
The effect of cushion block 140 is mainly to support main scale 110, pit gauge 120 and sway brace 130.Simultaneously, cushion block 140 can also guarantee that main scale 110 is parallel with the bottom surface of measured trapezoidal workpiece 200, makes trapezoidal workpiece inwall lateral dimension measurement mechanism 100 can measure exactly trapezoidal workpiece inwall lateral dimension.In the present embodiment, cushion block 140 1 has 3, and these 3 cushion blocks 140 are arranged on the middle part of main scale 110 equidistantly.Certainly, the number of cushion block 140 is not limited to 3, also can be for more than 3.Simultaneously, cushion block 140 is adjustable at the height perpendicular on main scale 110 directions.But in order to realize the regulatory function of cushion block 140, one knob and a double-screw bolt can be set on cushion block 140, double-screw bolt is for connecting cushion block 140 and main scale 110, it is flexible on cushion block 140 that knob can be regulated double-screw bolt, thereby regulate the distance between main scale 110 and cushion block 140, just can realize that by the rotation knob cushion block 140 is in the Height Adjustable function perpendicular on main scale 110 directions like this.That is to say, by regulating 140 at the height perpendicular on main scale 110 directions, can change the distance between main scale 110 and measured trapezoidal workpiece 200 bottom surfaces, thereby can measure the lateral dimension that trapezoidal workpiece inwall is positioned at differing heights.
Below simply introduce the using method of trapezoidal workpiece inwall lateral dimension measurement mechanism 100.
Regulate cushion block 140 at the height perpendicular on main scale 110 directions, make main scale 110 parallel with measured trapezoidal workpiece 200 bottom surfaces, again the angular shape of sway brace 130 132 is contacted with the inwall of measured trapezoidal workpiece 200, then release the surveyingpin 122 of pit gauge 120, until surveyingpin 122 contacts with the inwall of trapezoidal workpiece, numerical value on registered depth chi 120 digital indicators 124, now the numerical value on digital indicator 124 is only the length of surveyingpin 122 to inwall, obtain whole trapezoidal workpiece inwall lateral dimension and also will add the fixed part size.The length of fixed part refers to that main scale connects the total length of an end of pit gauge 120 to angular shape 132 most advanced and sophisticated places, and the length of this fixed part is known.
Be understandable that, the sway brace 130 in trapezoidal workpiece inwall lateral dimension measurement mechanism 100 also can replace with another pit gauge, thereby obtains the trapezoidal workpiece inwall lateral dimension measurement mechanism of another embodiment.
The cushion block 140 of above-mentioned trapezoidal workpiece inwall lateral dimension measurement mechanism 100 has guaranteed that main scale 110 can be parallel to the bottom surface of trapezoidal workpiece, therefore accuracy is higher, the length that pit gauge 120 can stretch out main scale 110 along with the actual length free adjustment surveyingpin 122 of tested distance simultaneously, and pit gauge 120 can be sticked in trapezoidal workpiece inwall by trapezoidal workpiece inwall lateral dimension measurement mechanism 100 fully with sway brace 130, make trapezoidal workpiece inwall lateral dimension measurement mechanism 100 can record size accurately, further guaranteed the accuracy of measurement result.In addition, add that by the digital indicator 124 on pit gauge 120 the fixed part size can obtain rapidly the lateral dimension of tested trapezoidal inwall.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
