Description

Technical Field

[0001] This utility model relates to the field of carbon skateboard technology, and in particular to a tooling for detecting the thickness of the end of a carbon skateboard. Background Technology

[0002] With the rapid development of high-speed rail, carbon sliding plates for pantographs are widely used in urban rail transit, for example... Figure 1 , Figure 2 The carbon slide plate shown is used in large quantities because it is a consumable part.

[0003] During the production of carbon skateboards, the thickness of the skateboard's ends must be strictly controlled. Therefore, in existing technologies, inspectors often use conventional measuring tools such as vernier calipers to measure the end thickness of carbon skateboards. For example... Figure 1 , Figure 2 The carbon skateboard shown needs to have its end thickness checked by the inspector. Furthermore, all carbon skateboards must undergo full inspection.

[0004] However, when using conventional measurement methods to measure the thickness of carbon slide plate ends, inspectors may need to check a single carbon slide plate multiple times to determine if its thickness meets the requirements. Moreover, multiple carbon slide plates need to be checked per day, and the repeated handling and observation are extremely inconvenient. Even slight errors in the inspection area can lead to inaccurate test results, resulting in low efficiency, increased workload for inspectors, and a significant impact on the carbon slide plate inspection progress.

[0024] like Figures 1-4 The figures show different structural diagrams of a carbon slide plate and the carbon slide plate end thickness detection fixture of the present invention. As can be seen from the figures, the carbon slide plate end thickness detection fixture of the present invention includes: a square detection plate; and a through hole opened in the center of the detection plate for inserting the end of the carbon slide plate to detect the end thickness of the carbon slide plate. The through hole is a square through hole.

[0025] Specifically, the carbon slide plate end thickness detection fixture of this utility model is used to detect the end thickness of an arc-shaped carbon slide plate. It includes a rectangular detection plate with a relatively thin thickness. The length of the detection plate is greater than the width of the carbon slide plate, and the width of the detection plate is greater than the thickness of the thickest part of the carbon slide plate. A square through hole adapted to the shape of the end of the carbon slide plate is opened in the center of the detection plate. By inserting the end of the carbon slide plate into the square through hole of the detection plate, it is possible to detect whether the end thickness of the carbon slide plate meets the preset requirements.

[0026] In this test, the size of one end of the through hole in the center of the test plate is larger than the size of the other end of the through hole, the size of one end of the through hole is less than or equal to the upper limit of the thickness of the end of the carbon slide plate to be tested, and the size of the other end of the through hole is less than or equal to the lower limit of the thickness of the end of the carbon slide plate to be tested.

[0027] In the design, one sidewall of the through hole is a straight sidewall 3 extending horizontally, and the sidewall opposite the straight sidewall is an inclined sidewall 1 extending in an inclined direction. The other two sidewalls that together with the straight sidewall and the inclined sidewall form the through hole are vertical sidewalls 2 that are parallel to each other and perpendicularly connected to the straight sidewall. The minimum dimension enclosed by the straight sidewall and the inclined sidewall is less than or equal to the lower limit of the thickness of the end of the carbon slide plate to be tested, and the maximum dimension enclosed by the straight sidewall and the inclined sidewall is less than or equal to the upper limit of the thickness of the end of the carbon slide plate to be tested.

[0028] The following describes the structure of the carbon slide plate end thickness detection tool of this utility model, taking a certain carbon slide plate that is detected by the carbon slide plate end thickness detection tool of this utility model as an example.

[0029] like Figures 5-8 The figures shown are schematic diagrams of different structures of a carbon slide plate whose end thickness is to be detected and the tooling for detecting the end thickness. Figure 5 , Figure 6It can be seen that the length l of the carbon slide plate is 1050, with an upper tolerance of +1 and a lower tolerance of -1; the width w of the carbon slide plate is 63.4; the thickness t of the center part of the carbon slide plate is 36.8, with an upper tolerance of +1 and a lower tolerance of -1; and the thickness t1 of the end of the carbon slide plate is 26, with an upper tolerance of +1 and a lower tolerance of 0. After the carbon slide plate is processed, it is necessary to quickly measure its end thickness dimension, i.e.,

[0030] In order to detect such Figure 5 , Figure 6 The carbon skateboard shown uses, for example, Figure 7 , Figure 8 The inspection fixture shown has an inspection plate with a length (a) of 75, a width (b) of 37, and a thickness (c) of 7. It has a through hole with unequal dimensions at both ends, with a distance (a1) between the two vertical sidewalls of the through hole of 65. The thickness (a-a1) between the horizontal sidewall of the through hole and the outer wall of the inspection plate is 5. The size of the through hole relative to the smaller end is... The size of the through hole relative to the size of the larger end is

[0031] The units for the above dimensions are the same as those for existing carbon skateboard dimensions, such as millimeters.

[0032] During testing, the end of the carbon slide plate to be tested is inserted into the through hole of the testing fixture, which has a size of [missing information]. At the port (during design, corresponding marks can be set at the corresponding port, such as color or text markings), if the end of the carbon slide plate can be inserted, it indicates that the thickness of the carbon slide plate end meets the upper limit tolerance requirement; otherwise, it indicates that the thickness of the carbon slide plate end is unqualified. After the above-mentioned end of the carbon slide plate passes the inspection, turn the inspection fixture around, and then insert the same end of the carbon slide plate to be inspected into the through hole of the inspection fixture with a size of [missing information]. If the carbon slide plate end cannot be inserted at the port (similarly, during the design, corresponding marks can be set at the corresponding port, such as color or word marks), it indicates that the thickness of the carbon slide plate end meets the lower limit requirement; otherwise, it indicates that the thickness of the carbon slide plate end is unqualified.

[0033] It is evident that the inspection fixture of this invention is suitable not only for process inspection in the manufacturing of carbon skateboards, but also for the inspection of finished carbon skateboards. The inspection is both fast and accurate, greatly improving the inspection efficiency.

[0034] Although the present invention has been described in detail above, the present invention is not limited thereto. Those skilled in the art can make modifications based on the principles of the present invention. Therefore, all modifications made in accordance with the principles of the present invention should be understood as falling within the protection scope of the present invention.
