Flash testers with telecentric lenses, CNC program mode quick settings, autofocus and other functions can realize the simultaneous measurement of the contour, roundness, axial or radial dimensions and angles of multiple products. Most of the stage of commercially available flash testers are designed with transparent glass. For example, the CN217585676U patent discloses a one-button flash tester, such as Figure 1 As shown, the upper frame of the flash tester includes a telecentric lens, a camera and a screw-top mechanism, wherein the screw-top mechanism is used to adjust the position of the telecentric lens; the lower frame B is equipped with a stage A, a connecting plate and a light-emitting lighting device; the stage A is made of transparent glass, the upper part of the stage A protrudes from the upper surface of the lower frame B, and the lighting device is located below the stage A. When measuring lightweight circular structural parts, due to the lack of constraints, the structural parts are prone to sliding or rolling on the smooth upper surface of the stage A, resulting in measurement failure, and may even scratch or damage the surface of the glass stage. Therefore, it is very necessary to achieve batch, rapid and accurate measurement of lightweight cylindrical ceramic structural parts through the cooperation of auxiliary tooling.

DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] As shown in the figure, the auxiliary tooling main body of the utility model is made of a transparent material in one piece. Specifically, the transparent material can be epoxy resin, which is integrally formed through a 3D printing process.

[0027] Specifically, the main body of the auxiliary tooling includes a square frame 1, on which a plurality of parallel and spaced positioning plates 2 are arranged in sequence, and the two ends of each positioning plate 2 are respectively connected to two opposite frames located at the front and rear sides of the frame 1, and the upper surface of each positioning plate 2 is sequentially spaced along the length direction of the positioning plate and provided with a plurality of positioning grooves 21; the lower surface of each side frame of the frame 1 is also provided with a lower protrusion 3.

[0028] The above is the basic structure of the auxiliary tooling main body of the utility model, and its function is: when a plurality of lightweight cylindrical ceramic structural parts (hereinafter referred to as "structural parts") are tested simultaneously in batches, the auxiliary tooling main body is integrally mounted on the stage A of the flash tester, and the lower protrusions 3 on the lower surfaces of the four side frames of the frame are respectively abutted against the side edges of the stage A protruding from the upper surface of the lower frame B to limit the position, thereby realizing the positioning of the auxiliary tooling as a whole relative to the stage A, and the two ends of each structural part are respectively supported and limited by the positioning grooves 21 corresponding to the two positioning plates 2, and finally the stable limit of each structural part on the auxiliary tooling relative to the stage A is realized, the accuracy of the measurement is guaranteed, and because the structural parts are not in direct contact with the upper surface of the stage A, the possibility of the structural parts scratching the upper surface of the stage A is avoided. In addition, the auxiliary tooling main body is made of a transparent material in one piece, which will not affect the measurement.

[0029] Furthermore, the frame body 1 is also provided with side baffles 4 on both side frames parallel to the positioning plate 2, and a gap is left between each side baffle 4 and the adjacent positioning plate 2 to avoid affecting the function of the positioning groove 21 on the adjacent positioning plate 2, and the height of the side baffle 4 is greater than the height of the positioning plate 2 to prevent the structural parts from sliding from this direction.

[0030] At the same time, the side baffle 4 also provides an installation base for the connector of the handle 5 assembly, which helps to control the frame thickness of the frame 1, thereby shortening the distance between the structural member and the stage A as much as possible, and helps to improve the measurement accuracy.

[0031] The handle 5 allows the operator to lift and place the tooling on the stage stably; after the test is completed, the operator can quickly remove the tooling through the handle and dispose of defective products in time. In addition, this design can also realize the rapid replacement of two toolings, thereby improving the inspection efficiency.

[0032] Furthermore, the positioning plates 2 on the frame 1 are arranged in pairs of two, and the spacing between the same pair of positioning plates 2 is smaller than the spacing between two adjacent pairs of positioning plates 2. Figure 2 As shown, positioning plates 2a and 2b are a pair, and positioning plates 2c and 2d are another adjacent pair. The spacing between 2a and 2b of the same pair is smaller than the spacing between 2b and 2c, and the spacing between 2b and 2c is the spacing between the two pairs of positioning plates. Compared with equal spacing, the spacing structure design of the positioning plates can make the auxiliary tooling applicable to structural parts of more lengths. It should be noted that when in use, the two ends of a structural part are not only supported and limited by the positioning grooves 21 of two adjacent positioning plates respectively. If the length of the structural part is long, it can span one or more positioning plates, for example, one end is supported and limited by the positioning groove of 2a, and the other end is supported and limited by the positioning groove of 2c, and the positioning groove of 2b is spanned in the middle.

[0033] Furthermore, the size specifications of the positioning grooves of each positioning plate 2 can not only be completely consistent, but also can be as follows: Figure 6 As shown, the positioning grooves 21 on each positioning plate 2 are divided into three groups: the first group of positioning grooves 21a, the second group of positioning grooves 21b and the third group of positioning grooves 21c. The size specifications of the positioning grooves in the same group are the same, while the size specifications of the positioning grooves in different groups are different. The ultimate purpose of the present utility model is to support and limit cylindrical structural parts, that is, the maximum diameters of the structural parts supported by the positioning grooves in the same group are the same, while the maximum diameters of the structural parts supported by the positioning grooves in different groups are different. Preferably, from the perspective of the arrangement order along the length direction of the positioning plate 2, the maximum diameters of the structural parts supported by the positioning grooves in each group increase successively, for example Figure 6 In the embodiment shown, the first group of positioning grooves 21a, the second group of positioning grooves 21b and the third group of positioning grooves 21c are suitable for increasing the maximum diameter of the structural member supporting the limit position in sequence, the second group of positioning grooves 21b is larger than the first group of positioning grooves 21a, and the third group of positioning grooves 21c is larger than the second group of positioning grooves 21b. The above structural form can realize the simultaneous measurement of the dimensions of lightweight cylindrical structural members with different diameters.

[0034] Preferably, Figure 6 As shown, the cross-section of the positioning groove 21 is an inverted triangle, that is, the positioning groove 21 is a V-shaped groove. The depth and width of the V-shaped groove determine the maximum diameter of the structural member for which it is suitable for supporting and limiting. The use of this type of positioning groove 21 can be downwardly compatible with the supporting and limiting of structural members with smaller diameters.

[0035] Preferably, at least two lower protrusions 3 are arranged in sequence and spaced apart on the lower surface of each side frame of the frame body 1 along the length direction of each frame itself, that is, there are at least two lower protrusions 3 on the same side frame, and no matter they are on the same side or adjacent sides, there is a gap between the two adjacent lower protrusions 3, so as to achieve weight reduction and shorten the width of a single lower protrusion 3, so that when the main part of the auxiliary tooling is integrally mounted on the stage A, it is convenient for the single lower protrusion 3 to be adaptively slightly bent, so as to achieve interference fit with the stage A through the lower protrusion 3, thereby enhancing the accurate positioning and fastening function between the device and the flash tester.

[0036] Preferably, Figure 5As shown, the surface area between two adjacent positioning grooves 21 on the upper surface of the same positioning plate 2 is used as the number position 22, and the sorting number is etched or written on the number position 22. For example, the sorting number on the number position 22 can be set by laser engraving or by engraving with a 0.3mm or 0.5mm ballpoint pen. The purpose of setting the sorting number on the number position 22 is to facilitate the operator to quickly confirm and pick out the unqualified products according to the test imaging results and the sorting number on the corresponding number position. Specifically, after the test is completed, the specific imaging photos of this measurement will be presented on the software interface, and the qualified and unqualified products will be marked with "OK" and "NG"; the operator can quickly find the unqualified products for processing (placed in the unqualified product tray) according to the corresponding sorting number on the number position next to the "NG" mark.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
