[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention shall not be limited thereto.

[0018] The invention is used for measuring the distance between points and between a point and a straight line on a processed part.

[0019] Please refer to Figure 1 and Figure 2 The measuring tool for the processing point is placed on the processed part, including a coordinate base shell 1, an X measuring ruler 2-1, a Y measuring ruler 2-2, a top seat 3, a measuring top 4 and a positioning top 5.

[0020] The coordinate base shell 1 is a right square, which is composed of an X-axis angle side 1-1 and a Y-axis angle side 1-2 that are perpendicular to each other. One end of the X-axis angle side 1-1 and one end of the Y-axis angle side 1-2 are fixedly connected to each other to form a measurement coordinate system; both the X-axis angle side 1-1 and the Y-axis angle side 1-2 are provided with size scales.

[0021] The positioning tip 5 is fixed at the end connection of the X-axis corner edge 1-1 and the Y-axis corner edge 1-2 by a screw 6. The lower part of the positioning tip 5 is an inverted cone, which can be closely connected with the measured circular hole to achieve the center positioning. The vertex of the inverted cone is a pointed top, and the pointed top is located at the origin of the measurement coordinate system.

[0022] The X-measurement ruler 2-1 is placed in parallel with the X-axis corner edge 1-1 of the coordinate base shell 1, one end of which is connected to the Y-axis corner edge 1-2 of the coordinate base shell 1, and can move along the Y-axis corner edge 1-2. The Y-measurement ruler 2-2 is placed in parallel with the Y-axis corner edge 1-2, one end of which is connected to the X-axis corner edge 1-1, and can move along the X-axis corner edge 1-1. The X-measurement ruler 2-1 and the Y-measurement ruler 2-2 intersect vertically. The X-axis corner edge 1-1 and the Y-axis corner edge 1-2 are provided with guide grooves in the longitudinal direction, and the ends of the X-measurement ruler 2-1 and the Y-measurement ruler 2-2 are provided with guide pins that cooperate with the guide grooves.

[0023] The top seat 3 is arranged at the vertical intersection of the X measuring ruler 2-1 and the Y measuring ruler 2-2, and is connected to the X measuring ruler 2-1 and the Y measuring ruler 2-2, and can slide on the X measuring ruler 2-1 and the Y measuring ruler 2-2 at the same time; the X-axis angle edge 1-1, the Y-axis angle edge 1-2, the X measuring ruler 2-1, the Y measuring ruler 2-2 and the top seat 3 form a rectangular measuring frame with variable side length.

[0024] The top seat 3 is provided with mutually perpendicular slide grooves for accommodating the X measuring ruler 2-1 and the Y measuring ruler 2-2 for sliding respectively. The two slide grooves are distributed in two layers and are not connected. The slide grooves are in sliding cooperation with the X measuring ruler 2-1 and the Y measuring ruler 2-2.

[0025] The measuring tip 4 is connected to the tip seat 3, and the center of the tip seat 3 is provided with a fixing hole for inserting the measuring tip 4. The X measuring ruler 2-1 and the Y measuring ruler 2-2 are provided with a long groove for accommodating the sliding of the measuring tip 4 in the longitudinal direction. The lower part of the measuring tip 4 is an inverted cone, which can be closely connected with the measured circular hole to achieve the center positioning. The apex of the inverted cone is a pointed top, which is located at the intersection of the X measuring ruler 2-1 and the Y measuring ruler 2-2, and is used to locate the measured processing point.

[0026] The method of measuring the distance of the machined parts by the measuring tool is as follows:

[0027] Measuring the distance between points - for example, measuring the distance between the centers of circular holes on machined parts.

[0028] First, one of the measured circular holes is used as the measurement reference point, and the positioning tip 5 is inserted into the reference circular hole. Since the reference hole is a circular hole, the inverted cone of the positioning tip 5 can fit tightly with the edge of the hole opening, and its tip automatically falls at the position of the center of the circular hole; then the X measuring ruler 2-1 is moved along the Y-axis angle edge 1-2, and the Y measuring ruler 2-2 is moved along the X-axis angle edge 1-1, so that the measuring tip 4 is placed in the other measured circular hole through the tip seat 3. Similarly, since the measured hole is a circular hole, the inverted cone of the measuring tip 4 can fit tightly with the edge of the hole opening, and its tip automatically falls at the position of the center of the measured circular hole; then, by reading the values ​​indicated by the size scales on the X-axis angle edge 1-1 and the Y-axis angle edge 1-2, the hole center distance of the two measured circular holes is calculated, thereby completing the measurement of the distance between points on the processed part.

[0029] Measurement of the distance between a point and a line - for example, measurement of the distance between the center of a circular hole on a machined part and the straight edge of the part.

[0030] First, the straight edge of the part is taken as the measurement reference point, the positioning tip 5 is placed on the reference line, and the X-axis angle edge 1-1 or the Y-axis angle edge 1-2 is made to coincide with the measured straight line; then the X measuring ruler 2-1 is moved along the Y-axis angle edge 1-2, and the Y measuring ruler 2-2 is moved along the X-axis angle edge 1-1, so that the measuring tip 4 is placed in the measured circular hole through the tip seat 3. Since the measured hole is a circular hole, the inverted cone of the measuring tip 4 can fit tightly with the edge of the hole mouth of the measured circular hole, and its tip automatically falls at the position of the center of the measured circular hole; then, by reading the value indicated by the size scale on the X-axis angle edge 1-1 or the Y-axis angle edge 1-2, the vertical distance from the center of the measured circular hole to the edge of the straight line can be obtained, thereby completing the measurement of the distance between a point on the machined part and the straight line.

[0031] It effectively reduces the extra work of the operator, avoids the problem of parts not being able to be measured and needing to be re-machined, improves processing efficiency and reduces labor costs.

[0032] The present invention utilizes the measuring tool for processing points to greatly improve the measuring efficiency and accuracy. On the other hand, the actual operation on site is also relatively simple and convenient, which effectively reduces the labor intensity and reduces the cost while ensuring the health of the operator.

[0033] The protection scope required by the present invention is not limited to the above-mentioned implementation cases, but should also include other obvious changes and alternatives to the present invention. All equivalent changes and modifications made according to the contents of the present invention belong to the scope of the present invention.
