[0031] In one embodiment of the present invention, Figure 1-4 As shown, a detection structure for chamfer measurement is provided, including a placement table 10, a light-emitting plate 20, a fixing plate 30, a limit block 40 and a measuring mechanism. A center table 101 is provided in the center of the placement table 10. A plurality of groups of circumferentially distributed light-transmitting grooves 11 are provided between the placement table 10 and the center table 101. The light-emitting plate 20 is arranged in the placement table 10 and is located below the light-transmitting grooves 11. The fixing plate 30 is arranged at the bottom end of the placement table 10 and is located below the light-emitting plate 20, and is used to fix the light-emitting plate 20 in the placement table 10. The limit block 40 is arranged on the placement table 10 and is located outside the light-transmitting groove 11, and is used to limit the position of the product. The measuring mechanism (not shown in the figure) is arranged above the center of the placement table 10, and is used to measure the size of the product.
[0032] In this embodiment, the measuring mechanism is a visual image testing device, such as a two-dimensional image measuring instrument, which is a well-known technology well known to those skilled in the art, so it is not described in detail. The measuring mechanism processes the image of the local illumination area of the product on the placement table 10, and then obtains the outer diameter of the chamfer of the product, thereby improving the measurement efficiency.
[0033] By setting a placement table 10, a light-emitting board 20 and a limit block 40, the product is placed on the center table 101 and quickly positioned by the limit block 40, thereby simplifying the positioning steps. After positioning, the light-emitting board 20 is started, and the light is transmitted through the light-transmitting groove 11 to locally illuminate the chamfered part of the product, so that the edge to be measured is revealed, and then the measurement is performed through the measuring mechanism, thereby completing the dimensional measurement of the chamfered outer diameter, simplifying the measurement steps, shortening the measurement time, improving the measurement efficiency, and reducing the cost.
[0034] Preferably, a plurality of connecting parts 12 are provided between the placement table 10 and the center table 101. The connecting parts 12 are located between two adjacent groups of light-transmitting grooves 11. The number of connecting parts 12 is determined according to the number of light-transmitting grooves 11. In this embodiment, there are four groups of light-transmitting grooves 11, and four groups of connecting parts 12 are formed between the four groups of light-transmitting grooves 11. By providing the connecting parts 12, the placement table 10 and the center table 101 are connected to ensure stability and fixity between the two.
[0035] Furthermore, the center table 101 is circular, and the outer diameter of the center table 101 is 36.9 mm to 37.5 mm. By setting the circular center table 101 to be consistent with the shape of the product, it is convenient to measure the chamfer of the product, improve the measurement accuracy of the product, and when testing products of different sizes, the user can select the placement table 10 corresponding to the outer diameter of the center table 101 according to the actual situation to measure the product, so as to adapt to the measurement of different products.
[0036] Specifically, the limit blocks 40 are provided in two groups, and the two groups of limit blocks 40 are symmetrically distributed on the placement table 10. The limit blocks 40 include a positioning portion 41 and a limit portion 42. The positioning portion 41 is provided on the placement table 10. The limit portion 42 is provided on one side of the positioning portion 41 and is used to limit the position of the product. During positioning, the two groups of limit portions 42 are in contact with the outermost edge of the product to achieve two-point positioning, so that the product can be quickly positioned, the positioning steps are simplified, and the test efficiency is improved.
[0037] Furthermore, an adjustment slot 411 is provided in the positioning portion 41, and the adjustment slot 411 is connected to the placement table 10 by screws. When fine-tuning, the screws are loosened, and the position of the positioning portion 41 on the placement table 10 is adjusted to move it to a desired position, and the screws are locked, thereby completing the adjustment of the limit block 40 to adapt to the testing of products of different sizes and improve the testing efficiency.
[0038] Furthermore, the limiting portion 42 is located above the connecting portion 12, and the width of the limiting portion 42 is not greater than the width of the connecting portion 12. By setting the width of the limiting portion 42 to be not greater than the width of the connecting portion 12, the limiting portion 42 is prevented from blocking the illumination area, thereby improving the test accuracy of the product and the measurement effect of the product.
[0039] Furthermore, the positioning portion 41 and the limiting portion 42 are integrally formed. By integrally forming the positioning portion 41 and the limiting portion 42, the processing of the limiting block 40 is facilitated, the processing steps are simplified, and the cost is reduced.
[0040] Preferably, the four corners of the placement table 10 are respectively provided with adjustment holes 13. Adjustment screws 14 are arranged in the adjustment holes 13. When the placement table 10 is tilted, the adjustment screws 14 at the tilted position are adjusted upward or downward to make the plane area of the placement table 10 parallel, thereby completing the horizontal adjustment of the placement table 10 and improving the measurement accuracy of the product.
[0041] Preferably, a lighting cavity 15 is provided in the placement table 10. The light-emitting board 20 is provided in the lighting cavity 15. Position limiting bosses corresponding to the light-emitting board 20 are provided on both sides of the lighting cavity 15. The position limiting bosses are provided to facilitate the installation and fixation of the light-emitting board 20, and simplify the installation steps of the light-emitting board 20.
[0042] Furthermore, both sides of the lighting cavity 15 are provided with wiring grooves 16 for placing the lighting wires. A wire pressing plate 17 for preventing the lighting wires from falling off is provided at the bottom of the placement platform 10. The wiring grooves 16 are provided to facilitate the fixing of the lighting wires, and to prevent the lighting wires from being arranged in a disorderly manner in the lighting cavity 15 and affecting the lighting effect. The wire pressing plate 17 is also used to limit the lighting wires to prevent the lighting wires from falling off.
[0043] like Figure 5 The light-emitting board 20 illuminates the product, and its irradiated light is diffracted upward. When the light irradiates the inner wall of the top of the lighting cavity 15, the light cannot penetrate, so that the outer surface of the corresponding area of the placement table 10 cannot be illuminated. The light irradiated into the light-transmitting groove 11 continues to diffract upward directly, and then locally illuminates the chamfered part of the product, showing the edge to be measured, which is convenient for the testing organization to perform image processing on the illuminated area and obtain the outer diameter of the chamfered part of the product.
[0044] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the utility model, which does not depart from the content of the technical solution of the utility model, belongs to the scope of the technical solution of the utility model.
