Description

Technical Field

[0001] This utility model relates to the field of detection devices, and in particular to a detection mechanism for detecting verticality. Background Technology

[0002] The Z-axis is perpendicular to the X and Y axes. During the assembly and adjustment of an image measuring instrument, the perpendicularity of the Z-axis to the X and Y axes is a crucial technical parameter. Currently, there are two methods for checking the Z-axis perpendicularity. The first method involves placing a right-angle gauge on the worktable and attaching a dial indicator to the Z-axis. As the Z-axis moves up and down, the operator observes the movement of the dial indicator needle and calculates the perpendicularity. Its structure is as follows: Figure 1 As shown; the second method uses the reflector of the image measuring instrument as the light source, moves the camera and lens on the Z-axis of the image measuring instrument to focus, uses dedicated software of the image measuring instrument to capture the two stepped circles on the fixture, determines the center coordinates of the two circles, and then calculates the center offset of the two circles, thereby obtaining the Z-axis perpendicularity data of the image measuring instrument. Its structure is as follows. Figure 2 As shown.

[0003] The above-mentioned detection methods all have significant drawbacks. The first method is cumbersome and inefficient, and its operation is extremely inconvenient due to space limitations after the Z-axis housing of the imaging device is installed. The second method uses a reflected light source to illuminate the stepped cylindrical fixture and employs imaging device software to capture the fixture's outline. However, the captured outline lacks clear distinction between light and dark areas, and traces may exist on the fixture surface and working plane, interfering with the software's contour capture and resulting in low accuracy in determining the outline's position. Therefore, it is necessary to propose a new solution to address these problems. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a detection mechanism for detecting perpendicularity, which can effectively solve the problems of cumbersome operation, low detection efficiency and low detection accuracy of the existing Z-axis detection method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A testing mechanism for detecting verticality includes a platform, a fixture, and a light source. The platform is made of a light-transmitting material. The fixture is placed on the platform and is also made of a light-transmitting material. The fixture includes a main body and a boss. The boss extends upward from the center of the upper surface of the main body, and the center of the boss and the center of the main body are vertically aligned. The main body has a slot. The light source is placed below the platform, and the light emitted by the light source is vertically upward.

[0007] As a preferred embodiment, the slot is formed on the upper end face or the lower end face of the main body.

[0008] As a preferred embodiment, a step extends upward from the center of the upper surface of the main body, and the boss extends upward from the center of the step.

[0009] As a preferred embodiment, the main body is cylindrical, and correspondingly, the boss is also cylindrical.

[0010] As a preferred embodiment, the light source is located directly below the fixture.

[0011] As a preferred embodiment, the light source is a transmission lamp.

[0012] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0013] By moving the lens and camera of the image measuring instrument up and down along the Z-axis, the dedicated software of the image measuring instrument captures the contour of the fixture. In addition, the light source is set below the platform, and the direction of light emitted by the light source is vertically upward. The main body has a slot to reduce the medium through which the light emitted by the light source passes, ensuring that the light emitted by the light source can completely pass through the fixture. This makes the dedicated software of the image measuring instrument capture a clear contour image of the fixture with accurate contour position, which greatly improves the detection accuracy. Moreover, it is simple to operate and has high detection efficiency.

[0014] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0024] Please refer to Figure 3 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a platform 10, a fixture 20, and a light source 30.

[0025] The platform 10 is made of a light-transmitting material.

[0026] The fixture 20 is mounted on the platform 10 and is also made of a transparent material. The fixture 20 includes a main body 21 and a boss 22. The boss 22 extends upward from the center of the upper surface of the main body 21, and the center of the boss 22 and the center of the main body 21 are directly opposite each other. The main body 21 has a slot 211. In this embodiment, the slot 211 can be opened on the upper surface or the lower surface of the main body 21. Specifically, in this embodiment, the slot 211 is opened on the upper surface of the main body 21. In addition, a step 23 extends upward from the center of the upper surface of the main body 21, and the boss 22 extends upward from the center of the step 23. This design allows the software to capture the outline of the boss 22 and the main body 21 more clearly. The main body 21 is cylindrical, and correspondingly, the boss 22 is also cylindrical.

[0027] The light source 30 is located below the platform 10, and the light emitted by the light source 30 is vertically upward. In this embodiment, the light source 30 is located directly below the fixture 20, and the light source 30 is a transmission lamp.

[0028] The usage method of this embodiment is described in detail below:

[0029] In the image measuring instrument, a support 40 that moves with the Z-axis is set on the Z-axis. The camera 50 and lens 60 are both set on the support 40. The detection mechanism for detecting verticality described in this utility model is placed in the image measuring instrument and located below the camera 50 and lens 60. The Z-axis is started, and the Z-axis drives the support 40 to move up and down, which in turn drives the camera 50 and lens 60 to move up and down. At the same time, the special software of the image measuring instrument is used to capture the contour of the fixture. After determining the coordinates of the center of the main body 21 and the center of the boss 22, the offset of the two centers during the up and down movement of the camera 40 and lens 50 is calculated, and the verticality data of the Z-axis 60 can be obtained.

[0030] The key design feature of this utility model is:

[0031] By moving the lens and camera of the image measuring instrument up and down along the Z-axis, the dedicated software of the image measuring instrument captures the contour of the fixture. In addition, the light source is set below the platform, and the direction of light emitted by the light source is vertically upward. The main body has a slot to reduce the medium through which the light emitted by the light source passes, ensuring that the light emitted by the light source can completely pass through the fixture. This makes the dedicated software of the image measuring instrument capture a clear contour image of the fixture with accurate contour position, which greatly improves the detection accuracy. Moreover, it is simple to operate and has high detection efficiency.

[0032] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
