Abstract

The utility model provides a measuring appliance, namely a hole inclination measurement device which is simple in structure, convenient and fast in use and can directly measure gradients of axial leads of various inner holes. The device is mainly composed of a supporting plate 1, a set rule 2, a pointer 3, a leaning needle 4, a cover plate 5 and a pointer guard plate 9. The pointer 3 is positioned on the facade of the supporting plate 1 and is connected therewith by a hinge 6, so the pointer 3 can rotate by taking the hinge 6 as a pivot, and the set rule 2 is positioned in a chute combined by the back of the supporting plate 1 and the cover plate 5 and can slide along the chute up and down, according to the self-alignment principle of cone, a positioning working face of the set rule 2 is processed into a taper shape, center lines of the set rule 2, the pointer 3 and the leaning needle 4 are collinear with the center line of the supporting plate 1, the leaning needle 4 is positioned on the back of the lower end of the pointer, and the leaning needle 4 swings to drive the pointer 3 to rotate, so the gradient of an axial lead of an inner hole of a test workpiece can be directly read out through the pointer 3 and the graduation on the facade of the supporting plate 1.

Description

The hole deviation measuring appliance

Affiliated technical field

The utility model relates to a kind of measuring appliance of measuring endoporus axial line degree of tilt.

Background technology

At present, be a great problem in that endoporus axial line degree of tilt is directly measured.

Summary of the invention

1. it is complicated and also need to calculate to measure the measuring method of endoporus axial line degree of tilt at present, and not only efficient is low and poor accuracy.The purpose of this utility model provides a kind of easy, quick and higher measuring appliance of accuracy.The utility model solves the scheme that its technical matters takes: the self-centering principle of utilizing tapering; the positioning reference plane of positioning rule 2 is processed into the tapering inclined-plane to realize precision centering; form a chute between cover plate 5 and the supporting plate 1; positioning rule 2 can slide up and down to adapt to the measured workpiece in different apertures along chute; the lower end of pointer 3 is connected with to be measured by pin 4; by pin 4 downside two ends as the surveying work head and the point and approach; pointer 3 also is connected with supporting plate 1 by hinge 6; thereby pointer backplate 9 is connected the front of supporting plate 1 pointer 3 is shielded by screw 11; positioning rule 2; pointer 3 reaches by the center line of pin 4 and the centerline collineation of supporting plate 1; drive the pointer rotation by the beat that contacts the back generation by pin two ends workplace with hole wall, thereby realize the degree of tilt of workpiece endoporus axial line is directly measured according to the groove on pointer 3 and the supporting plate 1 again.

2. the beneficial effects of the utility model are: can and need not calculate the degree of tilt that can measure measured workpiece endoporus axial line not by any aid.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is that the utility model front view (FV) is a front view.

Fig. 2 is that the utility model back view is a rear view.

Embodiment

1, in Fig. 1: shown mutual alignment and annexation thereof between pointer 3 and supporting plate 1, the pointer backplate 9;

2, in Fig. 2: shown positioning rule 2 and supporting plate 1, supporting plate 1 and cover plate 5, pointer 3 and by mutual alignment and annexation thereof between the pin 4.

3, positioning rule 2 is shaped as rectangle but the both sides, lower end are tapering with the centering workplace (consulting Fig. 2) when measuring, cover plate 5 left sides, totally two on the right side, the vernier scale of shape and vernier caliper is similar, thereby be connected supporting plate 1 back side by screw 10 and be combined into a chute, positioning rule 2 is contained in the chute with on the realization positioning rule, lower slider (consulting Fig. 2), pointer 3 is connected with supporting plate 1 front by hinge 6 and can be fulcrum rotation (consulting Fig. 1) by hinge 6, be similar to isosceles trapezoid by pin 4 shapes, with its with register pin and screw retention at the tail end back side of pointer 3 (consulting Fig. 2), clamping

screw

7,8 respectively to pointer 3 and 2 brakings of positioning rule and fixation (consulting Fig. 1 and Fig. 2), pointer backplate 9 is shaped as the π font, is fastened on supporting plate 1 front with protection pointer 3 (consulting Fig. 1) with screw 11; 12 is measured workpiece.

Claims

1. hole deviation measuring appliance, it is characterized in that: the lower end of pointer 3 is connected with to be measured by pin 4, in the both sides of pointer 3 main bodys, is used for the contact measurement of work by pin 4 two ends measuring head balanced configurations, pointer backplate 9 is connected the front of supporting plate 1, and pointer 3 is connected by hinge 6 with supporting plate 1.

2. hole deviation measuring appliance according to claim 1, it is characterized in that: (1) pointer 3 tops are triangle, its most advanced and sophisticated indicator when measuring is so that corresponding with the groove on the supporting plate 1, the precision centering that both sides, (2) positioning rule 2 bottom are a tapering inclined-plane when realizing measuring.
