Description

Pin-and-hole location survey isolated plant

Technical field

The utility model relates to a kind of measurement mechanism, but especially relates on a kind of measuring workpieces pin-and-hole to the pin-and-hole location survey isolated plant of workpiece end face distance.

Background technology

Pin hole processing is a very common manufacturing procedure on workpiece, and still, the Working position of pin-and-hole is important parameters in the process, and the pin-and-holes of processing that adopt are determined apart from the distance of workpiece end face more.People at present adopts special-purpose calliper class measurer to measure pin-and-hole apart from the distance of workpiece end face or the distance that adopts the three-dimensional method to come test pin pitch-row workpiece end face, with the Working position of determining pin-and-hole and and adjustment equipment, but since adopt calliper class measurer measure pin-and-hole apart from workpiece end face apart from the time, how can't realize direct measurement, the data of measuring are inaccurate, cause the accuracy rate of measured value low, influence is to the adjustment of equipment and the machining precision of pin-and-hole; And use the long of three-dimensional method test pin pitch-row workpiece end face apart from the time, and influenced production to a certain extent, reduced production efficiency.

Summary of the invention

Technical problem to be solved in the utility model has provided a kind of pin-and-hole location survey isolated plant, and it has improved on the workpiece pin-and-hole to the adjustment precision of workpiece end face distance detection accuracy, detection efficiency and equipment, and easy to operate.

For solving the problems of the technologies described above, the technical solution of the utility model is: pin-and-hole location survey isolated plant, comprise body, described body is provided with two register pins that can insert in the workpiece pin-and-hole to be measured, be respectively equipped with the thrust unit that can promote in the register pin slip insertion workpiece pin-and-hole to be measured between register pin and the body, described pin-and-hole location survey isolated plant also comprises the guide-localization piece that described body two ends are respectively equipped with, and is respectively equipped with the measurement display device on the described guide-localization piece.

As a kind of improvement, described thrust unit is a spring.

As further improvement, described measurement display device is a milscale.

As further improvement, be provided with milscale respectively near both ends on the described guide-localization piece.

The pin-and-hole location survey isolated plant of technique scheme, owing to be to have adopted on body, to be provided with two register pins that can insert in the workpiece pin-and-hole to be measured, be respectively equipped with the thrust unit that can promote in the register pin insertion workpiece pin-and-hole to be measured between register pin and the body, and the guide-localization piece that is respectively equipped with at the body two ends, on the guide-localization piece, be respectively equipped with the measurement display device, like this pin-and-hole to be measured on the measuring workpieces to workpiece end face apart from the time, earlier with this measurement mechanism at standard workpiece colonel measuring basis just in time, high-ranking officers' measurement mechanism just in time moves on on the workpiece for measurement by body two ends guide-localization piece then, register pin is inserted on the workpiece in the pin-and-hole to be measured, by workpiece end face and the interaction of measuring display device, record pin-and-hole to be measured on workpiece both ends of the surface distances and the standard workpiece pin-and-hole apart from both ends of the surface apart from difference, and by with standard workpiece on pin-and-hole compare apart from the distance of both ends of the surface, draw its actual value, solve current employing calliper and can't directly measure the problem that three-dimensional method length detection time is forbidden and utilized to the measurement data that causes, improve the workpiece pin-and-hole to the workpiece end face distance detection accuracy, the adjustment precision of detection efficiency and equipment.Thrust unit adopts spring, measures display device and adopts milscale, and be provided with milscale respectively near both ends on the guide-localization piece, and is not only simple in structure, be convenient to operation, and measured value is directly perceived.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Fig. 1 is the structural representation of the utility model pin-and-hole location survey isolated plant;

Fig. 2 is Fig. 1 vertical view.
