Abstract
The utility model discloses a shallow-step-hole diameter-size measurement device mainly including a dial gauge (1), a support ring (2), a pressing plate (3), screws (4) and a positioning pin (5). The support ring (2) is a circular ring with certain rigidity and a clamping groove and connecting threads are arranged on the support ring (2). A support end of the dial gauge (1) is fixed in the clamping groove of the support ring (2) through the pressing plate (3) and the screws (4). The positioning pin (5) is a fixed contact of the measurement device and is connected with threads on the support ring (2) through threads on the positioning pin (5). The shallow-step-hole diameter-size measurement device is capable of carrying out measurement of a diameter size of a shallow step hole which has a comparatively large size and higher precision demands and improved in detection efficiency of bulk products. The shallow-step-hole diameter-size measurement device is simple in structure, low in cost and convenient to operate.
Description
Technical field
The utility model relates to a kind of shallow stepped hole diameter dimension measurement mechanism, belongs to the mechanical measurement field.
Background technology
In the processing of product parts and components, often can run into some diameter dimensions larger, accuracy requirement is higher; and the shallow stepped hole of depth dimensions between 2～4mm; can not meet accuracy requirement with conventional vernier caliper measurement, because step hole depth is too shallow, can not measure with micrometer inside caliper again.In order to address this problem, improve measuring accuracy and the detection efficiency of shallow stepped hole diameter dimension, need a kind of measurement mechanism of measuring shallow stepped hole diameter dimension that is specifically designed to badly.
Summary of the invention
The technical matters that the utility model solves: the defect existed for overcoming traditional diamond-making technique, realize the measurement of the shallow stepped hole diameter dimension to thering is certain accuracy requirement, providing a kind of can carry out the device of accurately measuring to this size.
The technical solution of the utility model:
A kind of shallow stepped hole diameter dimension measurement mechanism of the utility model, mainly by clock gauge (1), bracing ring (2), pressing plate (3), screw (4), register pin (5), formed, bracing ring (2) is the annulus with certain rigidity, be processed with draw-in groove and connecting thread on it, the support end of clock gauge (1) is fixed in the draw-in groove of bracing ring (2) by pressing plate (3), screw (4), register pin (5) is the fixed contact of measurement mechanism, and it is connected with the screw thread on bracing ring (2) by the screw thread of self.
The beneficial effects of the utility model have:
1, the utility model can be realized the measurement to the shallow stepped hole diameter dimension of large-size, degree of precision requirement, has improved the detection efficiency of bulk article.
2, utilize clock gauge as measuring display unit, effectively improved measuring accuracy.
3, the utility model has been expanded the range of application of clock gauge.

Fig. 1 is front view of the present utility model
Fig. 2 is stereographic map of the present utility model
Embodiment
Embodiment of the present utility model: describe in conjunction with Fig. 1.
As shown in fig. 1, the shallow stepped hole diameter dimension of the utility model measurement mechanism is mainly consisted of parts such as clock gauge (1), bracing ring (2), pressing plate (3), screw (4), register pins (5).Clock gauge (1) is the display unit of measurement mechanism; Bracing ring (2) is the annulus with certain rigidity, be processed with draw-in groove and connecting thread on it, mainly play support and connection clock gauge (1) and register pin (5), the diameter of bracing ring (2) is determined by the pore size of required measurement; Pressing plate (3), screw (4) are retaining elements, for clock gauge (1) is fixed in the draw-in groove of bracing ring (2); Register pin (5) is the fixed contact of measurement mechanism, can make the product of series length size, and is selected according to measuring diameter, and it is connected by screw thread with bracing ring (2).
Using method of the present utility model is as follows:
1, size calibration
The size of the aperture size of measuring at first as required, choose applicable measurement mechanism, and the bracing ring of respective diameters size (2) and register pin (5), then carry out initial calibration with the outside micrometer of dimension.
2, measure
The register pin (3) of take is fixed contact, and clock gauge (1) is moving contact, and the stepped hole internal diameter is measured.By the upper scale shown of clock gauge (1), the size while adding initial calibration, just can obtain the stepped hole internal diameter size.
Claims (1)
1. a shallow stepped hole diameter dimension measurement mechanism, mainly by clock gauge (1), bracing ring (2), pressing plate (3), screw (4), register pin (5), formed, it is characterized in that: bracing ring (2) is the annulus with certain rigidity, be processed with draw-in groove and connecting thread on it, the support end of clock gauge (1) is fixed in the draw-in groove of bracing ring (2) by pressing plate (3), screw (4), register pin (5) is the fixed contact of measurement mechanism, and it is connected with the screw thread on bracing ring (2) by the screw thread of self.
