Detailed Description

The technical solution of the invention is described in further detail below with reference to specific embodiments and with reference to the attached drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

Example (b):

as shown in fig. 1, the cross section of the magnetic shoe is: the arc-shaped cross section comprises a top arc line and a bottom arc line, the circle centers of the two arc lines are on the symmetrical line of the cross section and are not in a concurrent point, and the radiuses of the two arc lines are different. Two ends of each arc line are respectively connected through a side wall line, the side wall lines are symmetrically arranged, the intersection points of the two side wall lines are also on the symmetrical line, the included angles of the two side wall lines are different according to different models of the magnetic tiles, and the included point is an angle vertex X; two virtual rays are symmetrically arranged at the circle center of the top arc line, the included angle of the virtual rays is the same as the included angle of the side wall line, and the value to be guaranteed is the offset distance between the virtual rays and the side wall surface.

This value is difficult to detect because of the high accuracy requirements. In addition, the position of the vertex X of the angle or the extension line of the side wall surface is virtual and cannot be directly obtained, in order to simplify the measurement process, the position is converted into the length between the highest point K of the top cambered surface 1 of the magnetic shoe and the vertex X of the angle through conversion, so that a virtual quantity is reduced, and the virtual quantity can be conveniently converted into real data which can be directly measured only by obtaining the position of the vertex X of the simulated angle through a tool.

As shown in fig. 2, 3 and 4, a magnetic shoe detects frock, magnetic shoe are equipped with the top cambered surface 1 of evagination and the lateral wall face 2 that links to each other with top cambered surface 1, including first anchor clamps 3 and second anchor clamps 4, be equipped with first recess 5 on the second anchor clamps 4, be equipped with second recess 6 on the first recess 5, second recess 6 laminating top cambered surface 1 is equipped with first lug 7 on the first anchor clamps 3, first lug 7 and first recess 5 adaptation are equipped with secondary recess 8 on the first lug 7, be equipped with the lateral wall 12 with the laminating of lateral wall face 2 on the secondary recess 8, second anchor clamps 4 lid dress is on first anchor clamps 3, and the magnetic shoe setting is between first anchor clamps 3, second anchor clamps 4. The first clamp and the second clamp are respectively provided with a first step 9 matched with the first clamp, and a second step 10 matched with the first convex block and the first groove. The outer side surface of the first bump 7 is a vertical surface vertical to the bottom surface. The intersection of the two side wall 12 faces of the secondary recess 8 is located on the bottom face of the first clamp 3. The first clamp 3 is divided into two abutting blocks 11 by the first bump 7, and the abutting blocks 11 are attached to the top surface of the second clamp 4. The first clamp 3 and the second clamp 4 are subjected to chamfering treatment at each edge. The first clamp 3 is higher than the second clamp 4.

The point of the bottom surface of the first clamp corresponding to the line of symmetry is called point O. Therefore, the positioning magnetic shoe is clamped through the matching of the first clamp and the second clamp, then the distance from the highest point K' of the secondary groove 8 of the second clamp 4 to the bottom surface O point of the first clamp 3 can be obtained through measurement in advance, then a corresponding correction value is obtained through comparison with an ideal value, in the subsequent detection, the actual distance from the angle vertex X of the product to the top arc surface 1 can be obtained only through measuring the distance from the highest point K of the top arc surface 1 of the magnetic shoe to the bottom surface O point of the first clamp and adding or subtracting the correction value brought by the tool, and then whether the product is qualified or not can be simply obtained through comparison with the corresponding ideal value.

In order to achieve the object that the distance between X and O is as close as possible, the extensions of both side wall surfaces of the secondary groove 8 are made as close as possible to the bottom surface, i.e., O. Thus, the correction value can be reduced, and the accuracy can be improved.

The arrangement of the steps in the above structure brings about an advantage that: by adjusting the position of the bottom surface of the first jig 3, the angle vertex X is set on the bottom surface of the first jig 3. In this way, when the product is a qualified product, the two steps should be fitted or the gap between the two steps is extremely small, and the magnetic shoe is fitted between the two clamps rather than in a loose state. The structure can be used for rapidly judging whether the product is qualified or not without detecting, so that the detected numerical value is displayed more visually. The structure can further improve the efficiency and the cost of detection.
