The main table 102 in the present disclosure is made of a structure that is not easily deformed, and has a high surface flatness, such as marble or stainless steel plate or aluminum alloy plate. The threaded hole of the base 101, this structure is mainly to ensure the flatness of the upper surface and ensure the installation accuracy. Of course, in practical applications, gaskets of different thicknesses can be used to adjust the horizontal accuracy after assembly to ensure that the two slide bars (to be described below) are in the same position. The horizontal height, the flatness of the base 101 after installation, will not be deformed by screw tightening, resulting in changes in the shape of the profiling surface.

The workbench 1 in the present disclosure includes a base 101 and a main table 102 that are detachably connected. The upper surface of the base 101 is provided with a placement position 1011 for placing the product 5 to be tested. The purpose of the detachable connection between the base 101 and the main table 102 is to It can be applied to a variety of products that need to detect the contour;

It should be noted that when testing the profile of different products 5 to be tested, it is necessary to install the base 101 and the detection part 2 corresponding to the product 5 to be tested on the main table 102, and the product 5 to be tested needs to be a single Axially curved products.

The function of the reference part 1012 is to facilitate testers to observe whether the product 5 to be tested is a qualified product after being tested by the test piece 2. When the test piece 2 moves along the first direction and passes through the entire upper surface of the product 5 to be tested, it is After completing a test, if the product 5 to be tested is an unqualified product, then the product 5 to be tested will be in contact with the test piece 2. As the test piece 2 moves, the test piece 2 will drive the product 5 to be tested to move together. At this time, By observing whether the product 5 to be tested moves relative to the reference part 1012 , it can be judged whether the product 5 to be tested is a qualified product.

The reference part 1012 can be constructed in any suitable manner according to actual application requirements. For example, in some embodiments, as shown in FIG. Between, the extension direction of the reference line is parallel to the outline of the lower side edge of the second side when the standard product 6 is placed in the placement position 1011. In this way, when the product 5 to be tested touches the detection part 2, by observing the positional relationship between the product 5 to be tested and the reference line, it can be concluded whether the product 5 to be tested is a qualified product.

Contour detection, when it is necessary to detect different uniaxial bending products, after the detection of the last product 5 to be tested, the detection part 2 and the base 101 need to be replaced. After the replacement, the detection part 2 and the Assembling errors will inevitably occur in the distance between the bases 101, which will affect the subsequent detection of the profile of the product 5 to be tested. At this time, the rapid positioning of the detection part 2 and the base 101 can be realized through the positioning part 1013 and the positioning matching part 201.

The positioning part 1013 and the positioning matching part 201 can be configured in any suitable manner according to actual application requirements. For example, shoulders are formed at opposite ends of the base 101 along the second direction, and the placement position 1011 is located between the two shoulders. The two shoulders are positioning parts 1013; the detection piece 2 is configured as a detection plate extending in the vertical direction, and the opposite ends of the detection plate along the second direction are formed with inverted L-shaped positioning grooves that match the shoulders. The detection part 202 is located between two positioning grooves, and the two positioning grooves are the positioning matching parts 201 .

The opposite ends of the test plate along the second direction are formed with inverted L-shaped positioning grooves that match the shoulders. After the test piece 2 and the base 101 are installed, it is necessary to ensure that the gap after installation is 0.01-0.03mm. Insert it into the gap between the positioning part 1013 and the positioning matching part 201 to confirm that the detection part 2 and the base 101 are in the expected assembly position through the plug gauge, and to ensure the gap accuracy between the installed detection part 2 and the placement position 1011 , to ensure the accuracy of the test.
