Description

Technical Field

[0001] The utility model relates to the technical field of optical parts processing, and more specifically to an angle measuring device based on a full-Euclidean goniometer. Background Art

[0002] At present, the height of the measuring light source of the full-Europe goniometer from its own measuring platform is only 110mm, and the effective measuring height is 55mm~110mm. When measuring the angle of a product at a certain height, it is necessary to adjust the product to achieve the measurement of the angles of the product at different heights. However, due to the height limit of the measuring light source from its own measuring platform, it is impossible to measure the angle of the part at any height. From the measurement operation point of view, when we measure the angle (dihedral angle) of the product, we need to adjust the reflected image of each measuring surface to the center of the field of view, and calculate the measured angle by the distance between the reflected images of the two surfaces. When adjusting the reflected image of the measuring surface, it is necessary to adjust it through the measuring platform adjustment knob of the full-Europe measuring instrument itself. The knob is not convenient to operate, and it is easy to accidentally touch the measuring platform during the adjustment process, causing the reflected image to jump out of the field of view. How to break the limitation of the part measurement height, realize the measurement of the angles of the part at different heights, and make the operation convenient and flexible has become an urgent problem to be solved.

[0003] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

The terms "first" and "second" are only used for the convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0027] The following describes the angle measuring device based on the full-Europe goniometer in the embodiment of the utility model in conjunction with the accompanying drawings. The angle measuring device is based on the full-Europe goniometer and includes two parts: a collimator platform and a product measurement platform. The problem of the full-Europe goniometer's limited optical part measurement height and inconvenient knob operation due to its own design height and design structure is solved, and the device is easy to operate and control.

[0028] See also Figure 1 , Figure 1An angle measuring device based on a full-Europe goniometer provided by the present application is shown, and the angle measuring device includes: a collimator platform 2, a product measuring platform 3 and a mounting platform 1, the collimator platform 2 and the product measuring platform 3 are arranged on the mounting platform 1 at intervals, the collimator 4 is arranged on the top of the collimator platform 2, the collimator platform 2 drives the collimator 4 to move in a direction perpendicular to the mounting platform 1, the product operating platform 31 is arranged at the upper end of the product measuring platform 3, and the product measuring platform 3 can drive the product operating platform 31 to move in three dimensions in space.

The three-dimensional movement is the movement in the X direction and the Y direction on the horizontal plane, and the movement in the Z-axis direction perpendicular to the horizontal plane. The mounting table 1 here can be regarded as a horizontal plane.

[0030] The collimator 4 on the collimator platform 2 is the light source for the full-Europe goniometer measurement system. The modified collimator platform 2 can adjust the height of the light source to achieve angle measurement of optical parts at different heights. It should be noted that the modification of the collimator platform must ensure the horizontality of the measurement light source and cannot change the emission angle of the measured light.

[0031] In addition, the product measurement platform 3 has an angle adjustment knob for the product measurement platform 3 that comes with the full-Europe goniometer, but the angle adjustment knob is located at the bottom of the product measurement platform 3, which is relatively close to the collimator platform 2. It is inconvenient to operate the angle adjustment knob, and it is easy to move the product measurement platform abnormally during adjustment, causing the reflected image of the optical parts placed on the product measurement platform 3 to move out of the measurement field of view. The modified product measurement platform 3 can realize convenient and rapid operation of adjusting the angle with the angle adjustment knob.

[0032] It should be noted that the lifting and lowering adjustment of the collimator platform 2 needs to adapt to optical parts of different heights, and the lifting and lowering adjustment feed unit of the collimator platform is in centimeters.

The collimator needs to be kept horizontal on the support platform to ensure that the emitted parallel light is vertically incident on the product measurement surface. The motor can drive the lifting platform to move up and down to drive the collimator to move up and down. The display operation screen shows the movement of the lifting platform.

[0035] like Figures 1 to 3 As shown, a clamping platform 25 and a clamping hoop 26 are provided on the support platform 24. The clamping platform 25 is provided with a clamping groove. The clamping hoop 26 is bolted to the clamping platform 25 to clamp the collimator 4 in the clamping groove.

The three-dimensional bracket 33 is used to adjust the movement of the optical parts in the three-dimensional direction of space to adapt to the detection of different surfaces of optical parts of different sizes. Before the detection, the three-dimensional bracket 33 is adjusted and kept still. During the detection process, the indicators of different surfaces of the optical parts can be detected by turning the knob of the digital disk.
