Hole centering and marking device

Abstract

The invention relates to a hole centering and marking device which comprises a barrel, a centering component and a marking component. The barrel comprises a barrel bottom and a barrel top which are perpendicular to a barrel body, the centering component and the marking component are respectively connected with the barrel body and are coaxial with the barrel body, the centering component is connected with the barrel body through a cover arranged on the barrel top, and the marking component is arranged at the center of the centering component. By the hole centering and marking device, center points of holes in different size and depth can be centered conveniently, the different center points can be marked conveniently, and positions of the holes can be determined easily. The hole centering and marking device is a special tool for marking centers of holes and is an auxiliary tool for measuring size, and can be applied to objects which are connected or matched mutually and have requirements for assembling, centering, hole-to-hole aligning, hole-to-column aligning and the like widely.

Description

technical field [0001] The invention relates to the fields of mechanical processing and surveying and mapping, in particular to a device for finding the centers of holes with different heights and marking them for measurement or processing marks. Background technique [0002] When we want to measure the position or distance of the hole of the actual object, we often encounter the embarrassment that we cannot find the center of the hole and cannot locate it accurately. For example, when the aperture is too large, too small, too deep, too shallow, etc., general measurement The instrument cannot be stably inserted into the measurement. If a large-scale three-coordinate measuring device is used for measurement, the cost is high, and it can only find the center position, and cannot form a mark. The utilization rate is extremely low, and it is not very useful for processing. The operation is relatively cumbersome. The measurement of the hole and the marking of the center of the h...
