Embodiment 1

[0028] Such as Figure 1 to Figure 6 As shown, a vernier-type comprehensive gauge for holes includes a gauge body with a scale line, a handle reference block 2, a vernier ruler 3, and an aperture measuring mechanism set on the gauge body. The graduation value on the gauge body 1 is 1mm , The graduation value on vernier 3 is 0.02mm. The handle reference block 2 is a cylinder with an outer diameter of 30 mm, which is larger than the commonly used hole diameter for processing, 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 18mm. The center angle of the vernier inserting port 5 on the peripheral surface of the handle reference block 2 is 90°, and the vernier 3 is in the shape of an arc tile. The outer peripheral surface of the gauge body 1 is matched with the inner concave surface of the vernier ruler 3. The handle reference block 2 is provide...

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 scale insertion opening 5 on the peripheral surface of the handle reference block 2 is 180°. The aperture measuring mechanism also includes a central sliding rod 12, an upper four-bar linkage group 13 and a lower four-bar linkage group 14. A radially penetrating notch 9 is provided between the two ends of the gauge body 1, and the notch 9 does not penetrate. At both ends of the gauge body 1, one inner wall of the notch 9 is provided with a sliding rod insertion groove 18 axially arranged along the gauge body 1. The sliding rod insertion groove 18 penetrates the top of the gauge body 1, and the cross section of the sliding rod insertion groove 18 is square. The cross section of the central slide bar 12 is also square. The central slide bar 12 is slidably arranged in the slide bar insertion groove 18 to realize the sliding connection with th...

Embodiment 3

[0034] The central angle of the vernier scale insertion opening 5 on the peripheral surface of the handle reference block 2 is 270°. The rest is the same as in Example 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 present invention relates to a measuring tool, more specifically, it relates to a comprehensive gauge for a vernier type hole. Background technique [0002] There are two main measurement items for machining holes in 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 carried out by the limit gauge, and the data is not judged during the measurement, but only qualified or not; Hole depth measurement, generally use general measuring tools, such as vernier depth calipers, the data read can be accurate to 0.02mm. Nowadays, some inspection tool manufacturers have designed comprehensive gauges that can detect whether the hole diameter and hole depth are qualified or not. However, when using this kind of comprehensive gauge to detect the depth of the processed hole, the scale of the reading scale is 1mm. The quality system standard TS16949 has MS...
