Description

Technical Field

[0001] The utility model relates to the technical field of profilers, in particular to a novel high-speed profiler. Background Art

[0002] A profilometer is a device that measures and records the shape, outline or curve of an object. By placing the object and scanning it with a detection probe, the shape of the object can be detected.

[0003] In the process of detecting an object, it is necessary to position the object to prevent it from moving and causing detection errors. For example, Chinese patent CN214372302U discloses a contour measuring instrument, including a workbench, both ends of the workbench are fixed with end plates, a first sliding rod is fixed between the end plates, one end of the end plates is fixedly embedded with a first bearing, a first screw rod is fixed between the first bearings, a first slider is slidingly sleeved on the outer wall of the first sliding rod, a first motor is fixedly provided on the outer wall of the end plate at one end, the rotating shaft of the first motor is fixedly connected to the first screw rod, and a lifting assembly is fixed on the first slider. Beneficial effects: the object to be detected can be clamped and fixed, so that the object is not easy to move during the detection process, the measurement error can be greatly reduced, and the object can be driven to rotate, so that the contour measurement from different directions of the object can be facilitated.

[0004] In the above technical scheme, the object is clamped and fixed by a clamp to ensure its stability, but the position of the detection probe remains unchanged, and a comprehensive detection is performed by adjusting the position of the clamped object, which makes the object move easily and cause unstable clamping, thereby causing the object position to shift. In the process of detecting objects of different sizes, it is necessary to adjust the distance between the detection probe and the object to facilitate the detection of the surface of larger objects. In view of this, the utility model proposes a new high-speed profilometer. Utility Model Content

When the adjusting screw 8 moves toward the center direction of the fixed ring 6, the adjusting screw 8 is rotated. When moving, the side surface of the object to be tested can be clamped and fixed by the arc clamping plate 10 to ensure that the object to be tested is located at the center of the fixed ring 6 and directly below the center of the disk 4 to prevent it from moving. Then, according to the size of the object to be tested, the position of the detection probe 5 is adjusted, and the hand wheel is turned to drive the screw rod 19 to rotate inside the linear guide 18, so that the slider 20 can be driven to slide inside the linear guide 18, and the position of the detection probe 5 is adjusted. Then, the drive motor 3 is turned on, and its operation drives the disk 4 and the detection probe 5 to rotate, so that the object to be tested can be fully detected.
