[0024] As Figures 3-4 As shown in different structure schematic view of carbon slide plate edge distance detection tool provided by the utility model, from the drawing, the utility model carbon slide plate edge distance detection tool includes: support plate 1 for setting the carbon slide plate to be detected on its one end face is the inclined end face forming the included angle greater than 0 degrees between adjacent end face, a plurality of positioning members 2 for positioning the multiple holes near the end face to be detected on the carbon slide plate are arranged on the upper surface of the support plate, the baffle 3 for positioning the end face of the carbon slide plate is vertically installed on the above one end face of the support plate, and the baffle extends along the inclined direction of the end face.

[0025] Specifically, the support plate is a flat plate, which is a trapezoidal plate, that is, as Figure 3 As shown, the upper and lower end faces are parallel, the left end face is the inclined end face forming the included angle greater than 0 degrees between adjacent end face (referred to as adjacent end face), and the right end face is the vertical end face perpendicular to the adjacent end face. When designing, the included angle between the left end face and the adjacent end face is the same as the included angle between the end face to be detected of the carbon slide plate (i.e. the end inclined surface of the carbon slide plate) and its adjacent end face.

[0026] In order to quickly position the carbon slide plate on the tool during detection of the carbon slide plate, a plurality of positioning members are arranged on the upper surface of the support plate, and the multiple holes 4 near the end face to be detected on the carbon slide plate are positioned by the plurality of positioning members respectively (see Figure 1 Two holes can be arranged on the end of the carbon slide plate, and the number of positioning members is also two, which can be seen from Figure 3 When designing, the number of positioning members is the same as the number of holes near the end of the carbon slide plate.

[0027] The positioning component is a positioning platform fixedly mounted on the support plate and extending perpendicular to the support plate. The positioning platform is frustoconical in shape, with the diameter of its bottom face connecting to the support plate greater than the diameter of its top face furthest from the support plate. The diameter of the bottom face of the positioning platform matches the diameter of the hole on the carbon slide plate. In the design, the lower limit of the diameter of the bottom face of the positioning platform is the lower limit of the diameter of the hole on the carbon slide plate, and the upper limit of the diameter of the bottom face of the positioning platform is less than the upper limit of the diameter of the hole on the carbon slide plate. The diameter of the top face of the positioning platform is approximately 1 mm smaller than the diameter of the bottom face of the positioning platform, while the height of the positioning platform can be approximately equal to the thickness of the support plate.

[0028] To locate the inclined end face of the carbon slide plate when detecting the edge distance, this invention includes a baffle plate near the inclined end face of the support plate. The baffle plate is vertically mounted on the upper surface of the support plate, and its length extends along the inclined direction of the inclined end face. The height of the baffle plate can be adapted to the thickness of the carbon slide plate end face.

[0029] In addition to the aforementioned carbon slide plate edge distance detection fixture, this utility model also provides a carbon slide plate edge distance detection component, which, in addition to the aforementioned carbon slide plate edge distance detection fixture, also includes a feeler gauge. During detection, the carbon slide plate is placed on the support plate of the detection fixture, and there is a certain gap between the end face of the carbon slide plate to be detected and the baffle. Whether the carbon slide plate edge distance meets the requirements can be determined by whether the feeler gauge can be inserted into the gap.

[0030] Below, we will discuss the detection capabilities. Figure 1 The tooling for detecting the edge distance of a carbon slide plate of the dimensions shown should be described.

[0031] like Figure 1 As shown, a certain carbon slide plate is a straight carbon slide plate. The tilt angle between its tilted end and the adjacent end is 75 degrees, with an upper tolerance of +10 degrees and a lower tolerance of -10 degrees. The distance between the center of the nearest hole to the tilted end and the tilted end is 35, with an upper tolerance of +0.3 and a lower tolerance of -0.3. The center distance between two adjacent holes is 30, with an upper tolerance of +0.3 and a lower tolerance of -0.3. The diameter of the hole is 8.5, with an upper tolerance of +0.05 and a lower tolerance of -0.05.

[0032] In order to detect Figure 1 The carbon skateboard shown uses, for example Figure 5 , Figure 6The detection tool is shown, the two edges of the support plate extending along the length direction are parallel to each other, the length of the long edge of the two edges is 80.49, the length of the short edge is 71.11, one edge adjacent to one end of the two edges is an inclined edge, and the other edge is a vertical edge, the inclined edge and the long edge or the short edge form an included angle with the inclined end of the carbon slide, that is, an included angle of 75 degrees, and the upper limit of the angle tolerance is +10 degrees, and the lower limit of the tolerance is -10 degrees. A baffle is arranged at a distance of 5 from the inclined edge of the support plate, the bottom of the baffle can be fixed on the upper surface of the support plate, the height of the baffle is 26, the upper limit of the tolerance is +0.05, the lower limit of the tolerance is 0, the baffle can also be fixed on the inclined end of the support plate, the height of the baffle is 31, the upper limit of the tolerance is +0.05, and the lower limit of the tolerance is 0. The length of the baffle is the same as the length of the inclined edge of the support plate, and both are 35. Two positioning tables are arranged on the support plate, the height of the two positioning tables is 5, the diameter of the top end face of the positioning table is 7.5, the upper limit of the tolerance is +0, and the lower limit of the tolerance is -0.05, the diameter of the bottom end face of the positioning table is 8.5, the upper limit of the tolerance is +0, and the lower limit of the tolerance is -0.05, the distance between the adjacent positioning tables is equal to the distance between the two holes on the carbon slide, that is, the center distance between the two adjacent positioning tables is 30, the upper limit of the tolerance is +0.05, and the lower limit of the tolerance is -0.05. The distance between the hole closest to the inclined end and the baffle is 35.8, the upper limit of the tolerance is 0, and the lower limit of the tolerance is -0.05. Then by Figure 5 、 Figure 6 It can be known that the distance (along the center line) from the hole center of the positioning table on the support plate to the inclined end is 35.5±0.3, that is, 35.2-35.9. Wherein, the units of the above-mentioned sizes are the same as the size units of the prior art carbon slide, such as millimeters.

[0033] When the detection tool is used to detect the edge distance of the left inclined end of the carbon slide, the hole on the left side of the carbon slide is correspondingly sleeved on the conical positioning table of the detection tool, and there is a certain gap between the inclined surface of the left end of the carbon slide and the inclined surface of the baffle of the detection tool. Then 0.5mm plug gauge is used for inspection, and the plug gauge cannot be inserted into the above-mentioned gap, which is qualified: when the 0.5mm plug gauge inspection cannot be inserted into the above-mentioned gap, if the maximum gap is 0.49mm, the minimum edge distance of the carbon slide is 35.26-35.31mm (35.75-0.49=35.26, 35.8-0.49=35.31), which meets the requirement that the edge distance of the carbon slide is 35, the upper limit of the tolerance is +0.3, and the lower limit of the tolerance is -0.3; when the 0.5mm plug gauge inspection cannot be inserted into the gap, if the minimum gap is 0.01mm, the maximum edge distance of the carbon slide is 35.74-35.79mm (35.75-0.01=35.74, 35.8-0.01=35.79), which also meets the requirement. The detection principle and method of the right edge distance of the carbon slide are the same as those of the left end.

[0034] It can be seen that the detection result calculated by the detection tool and the component detection of the utility model is in the range of the slide plate margin size, the detection margin is accurate, convenient and fast, the size precision is ensured and the efficiency is improved.

[0035] Although the application has been described in detail above, the application is not limited thereto, and those skilled in the art can make modifications according to the principles of the application, therefore, all modifications made according to the principles of the application should be understood as falling within the scope of the application.
