Rotary distance measuring instrument

Abstract

The invention discloses a rotary distance measuring instrument, which comprises a base; left and right ends on the upper surface of the base are connected with a first support and a second support which are provided with horizontal through holes; a spline shaft is arranged between the two supports in a penetrating way; two ends of the spline shaft respectively passes through the two horizontal through holes; one end of the spline shaft arranged outside the second support is connected with a plane bearing of which the inside is connected with a first shaft; the outer wall of the first shaft isconnected with a ball bearing; the outer wall of the ball bearing is connected with a rolling element; one end of the rolling element is connected with the side wall of the plane bearing, while the other end is connected with a contact plate; the spline shaft arranged between the second support and the plane bearing is sleeved with a spring; the spline shaft arranged between the first support andthe second support is sleeved with an adjustable slide block which is connected with a reading head; and the reading head and two connecting blocks are connected with a grating digital display ruler.The rotary distance measuring instrument has the advantages of simple structure, improvement of production efficiency, conservation of production time, and accurate control of sink depth.

Description

Technical field: [0001] The invention relates to a measuring device, in particular to a rotary distance measuring instrument. Background technique: [0002] In the port machinery industry, there are many large workpieces that need to be bored, and the workpiece itself is too heavy and too large for ordinary floor boring machines to process it. Large boring tooling, boring row and power head must be manufactured to meet this type of workpiece. The processing needs of these tools cannot control the depth of the counterbore when boring the counterbore. To control the depth of the hole, the length of the bored hole must be estimated first, but it must not reach the size, and then the boring The tool exits, measures the depth of the bored hole with a depth gauge, calculates the margin from the standard size, and then continues boring, and reaches the specified size by continuously withdrawing, measuring, calculating, and entering the tool, so that not only the size of the counter...
