Embodiment Construction

[0015] Such as figure 1 As shown, a central positioning device with a conical structure is a stepped structure as a whole, including a conical positioning part 1 and a central plane part 2. The conical positioning part includes two conical positioning surfaces up and down, and two conical The tapered slope of the shaped positioning surface is consistent with the tapered slope of the measuring fitting, and the structure of the tapered positioning part is matched with the tapered structure of the measured fitting. When the measured accessory is a concave structure, the conical center positioning device is a convex structure; when the measured accessory is a convex structure, the conical center positioning device is a concave structure. The central plane part 2 is a measuring plane, and a measuring plane is made on the positioning center plane of the conical central positioning device, and this plane is the center position of the conical central positioning device.

Abstract

The invention belongs to the technical field of an auxiliary device for mechanical manufacture measurement, is to solve the technical problems of low measuring precision, long measuring time and strict measurement space requirements caused when a conical structure center is measured through tools in the prior art and provides a conical structure center positioning device. The conical structure center positioning device is in a step structure wholly and comprises a conical positioning part and a center plane part. The conical positioning part comprises an upper conical positioning surface and a lower conical positioning surface. Cone inclination of the upper conical positioning surface and the lower conical positioning surface is consistent with that of a measurement part. The center plane part is a measurement plane. The measurement plane is arranged on a center plane of the two conical positioning surfaces. The conical structure center positioning device is simple in structure and convenient to use. The conical structure center positioning device improves center line measurement precision and efficiency, and the conical structure center positioning device can be used for measuring the conical structure center in any place.

Description

technical field [0001] The invention belongs to the technical field of auxiliary devices for mechanical manufacturing and measurement, and in particular relates to a center positioning device with a conical structure and a use method thereof. Background technique [0002] In the process of mechanical manufacturing, since the equilateral trapezoidal structure is a symmetrical structure with good orientation and central consistency, the trapezoidal structure is often used in the connection of accessories. For example, the connection between the brake beam pillar of the railway freight car and the brake beam beam frame adopts a tapered structure, between the axle box and the axle box draw bar of a certain type of railway engineering vehicle, between the frame and the axle box draw bar, and between the frame draw bar and the axle box draw bar. The mechanisms between the car bodies all adopt a tapered structure. However, it has always been a technical problem to determine the ce...
