Embodiment 1

[0028] Such as Figure 1 to Figure 6 As shown, a vernier-type comprehensive gauge for holes includes a gauge body 1 with scale marks, a handle reference block 2, a vernier ruler 3 and an aperture measuring mechanism arranged on the gauge body, and the graduation value on the gauge body 1 is 1 mm , the division value on vernier ruler 3 is 0.02mm. The handle reference block 2 is a cylinder, and its outer diameter is 30 mm, which is larger than the aperture of a commonly used machining hole, so that it is convenient to support the handle reference block 2 at the orifice. The main body of the gauge body 1 is also a cylinder, the cross-sectional diameter of the gauge body 1 is 18 mm, the central angle of the vernier ruler embedded opening 5 on the peripheral surface of the handle reference block 2 is 90°, and the vernier ruler 3 is in the shape of an arc tile, The outer peripheral surface of the gauge body 1 coincides with the inner concave surface of the vernier ruler 3 . The ha...

Embodiment 2

[0031] Such as Figure 7 to Figure 11 As shown, the cross-sectional diameter of the gauge body 1 is 14 mm. The central angle of the vernier ruler insertion opening 5 on the peripheral surface of the handle reference block 2 is 180°. The aperture measurement mechanism also includes a central sliding rod 12, an upper four-bar linkage 13 and a lower four-bar linkage 14, and a radially penetrating notch 9 is provided between the two ends of the gauge body 1, and the notch 9 does not pass through. At both ends of the gauge body 1, a sliding rod slot 18 is provided on the inner wall of the notch 9 along the axial direction of the gauge body 1. The sliding rod slot 18 runs through the top of the gauge body 1. The cross section of the sliding rod slot 18 is square. The cross section of the central sliding rod 12 is also square, and the central sliding rod 12 is adapted to slide and be arranged in the sliding rod slot 18 to realize the sliding connection with the gauge body 1, and the...

Embodiment 3

[0034] The central angle of the vernier ruler insertion port 5 on the peripheral surface of the handle reference block 2 is 270°. All the other are with embodiment 1.

Abstract

The invention discloses a vernier type comprehensive gauge for a hole. The vernier type comprehensive gauge comprises a gauge body with scale marks, a handle reference block, a vernier and an aperture measurement mechanism arranged on the gauge body, wherein an inner sliding cavity of which the two ends are open is formed in the handle reference block; the gauge body is adaptively arranged in the inner sliding cavity in a sliding penetration manner; the scale marks are axially arranged on the gauge body; a vernier embedding opening communicated with the inner sliding cavity is further formed in the circumferential surface of the handle reference block; the vernier is embedded into the vernier embedding opening; the aperture measurement mechanism comprises an aperture measurement main scale, a pair of radial verniers and a pair of internal diameter clamping legs; a radially through notch is formed between the two ends of the gauge body; the aperture measurement main scale is arranged in the notch in a penetration manner, exposed to the two sides of the notch, and perpendicular to the axis of the gauge body; the two radial verniers are connected to the aperture measurement main scale in a sliding manner, and are symmetrically distributed on the two sides of the axis of the gauge body. According to the vernier type comprehensive gauge, aperture and hole depth measurement accuracy can be improved, the vernier type comprehensive gauge is convenient to use, and working efficiency can be obviously improved.

Description

technical field [0001] The invention relates to a measuring tool, more specifically, it relates to a vernier type integrated gauge for holes. Background technique [0002] There are two main measurement items for the machining holes of mechanical products: one is the hole diameter and the other is the hole depth. In order to ensure the measurement efficiency, the general hole diameter measurement is to use the limit gauge for detection. The data is not judged during the measurement, but only whether it is qualified or not; The measurement of hole depth is generally detected by general-purpose measuring tools, such as vernier depth calipers, and the read data can be accurate to 0.02mm. Now some inspection tool manufacturers have designed a comprehensive gauge that can detect whether the hole diameter and hole depth are qualified or not at the same time. However, when using this comprehensive gauge to detect the depth of the processed hole, the scale division value used for re...
