Description

Optical measuring devices for different sizes

Technical Field

The present invention relates to the technical field of optical measurement, in particular to optical measurement devices of different sizes.

Background technique

The Chinese utility model patent with publication number CN213455480U discloses an optical measuring device for different sizes. The device is provided with a rotating motor, which drives a rotating inner gear ring to rotate through a gear meshing structure. The rotating inner gear ring drives a linkage frame to rotate around a rotating hole through a linkage shaft, thereby driving a measuring device body above to perform rotational measurement, so as to facilitate all-round measurement of detection objects of different sizes. During measurement, the inclination angle of the measuring device body and the distance relative to the detection object can be adjusted according to the needs of use, so as to facilitate the adjustment of the detection distance. The device can adapt to the measurement of objects of different specifications, and the adjustment structure is simple, easy to use, and suitable for popularization.

In the related art, when existing optical measuring equipment measures objects of different sizes, in order to improve its measuring distance and angle, a corresponding adjustment structure is generally provided to adjust the end of the measuring instrument. However, in the actual measurement process, since the workpiece is placed on a reference plate, its coverage surface cannot be measured, so the workpiece needs to be manually flipped and positioned and calibrated. The lack of automatic flipping and calibration functions reduces the convenience of using the optical measuring equipment.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Embodiment 1:

Referring to Figures 1-10, for optical measuring devices of different sizes, the top of the housing 1 includes an optical measuring instrument body 2 that is fixedly mounted and adjustable in height, a rotatable and adjustable substrate assembly 3 is arranged on the top of the housing 1, a flip assembly 4 for flipping a workpiece is arranged on one side of the housing 1, a calibration assembly 5 for calibrating the workpiece on the top of the substrate assembly 3 is arranged on the other side of the housing 1, a driving assembly 6 for driving the flip assembly 4 and the calibration assembly 5 left and right is arranged inside the housing 1, a movable shaft 7 is rotatably connected to the top of the housing 1, and a cleaning wipe 8 is fixedly connected to the outer surface of the movable shaft 7;

The optical measuring instrument body 2 adopts the optical measuring instrument in the prior art, and can realize fast and accurate measurement by borrowing computer technology;

By setting the base plate assembly 3, not only can the supported and stored workpiece be rotated to meet the measurement of workpiece rotation and adapt to the all-round measurement of test objects of different sizes, but also it is convenient for the flipping assembly 4 to flip the workpiece and for the calibration assembly 5 to calibrate the workpiece, thereby improving the convenience and accuracy of subsequent measurement;

The provision of the cleaning wipe 8 facilitates the staff to clean the storage surface of the substrate assembly 3, thereby preventing repeated measurements from causing contamination of the storage surface and affecting the accuracy of subsequent measurements.

The flip assembly 4 includes a T-shaped plate 41 slidably connected to the bottom of the inner wall of the housing 1, a U-shaped frame 42 is slidably connected to the top of the T-shaped plate 41, and a first electric cylinder 43 is fixedly connected to the top of the T-shaped plate 41, and the telescopic end of the first electric cylinder 43 is fixed to the bottom of the U-shaped frame 42, a rotating member 44 is provided on the top of the U-shaped frame 42, and an electric clamp 45 for fastening the workpiece is provided at the rotating end of the rotating member 44;

By driving the T-plate 41 to the left and right, the rotating member 44 and the electric clamp 45 can be driven to move horizontally. By setting the electric clamp 45, the workpiece on the substrate assembly 3 can be automatically clamped.

By starting the first electric cylinder 43, not only can the workpiece fastened by the electric clamp 45 be lifted, so that the workpiece loses contact with the substrate assembly 3, but also the rotating member 44 can be driven to rotate automatically, thereby realizing the flipping of the workpiece during the lifting process;

It not only has the function of automatic flipping to realize optical measurement of different surfaces of the workpiece, but also does not require manual operation, thus improving the orderliness and convenience of optical measurement.

Referring to Figures 7, 9 and 10, the rotating member 44 includes a fixed block 441 fixed to the top of the U-shaped frame 42, a rotating shaft 443 is installed inside the fixed block 441 through a one-way bearing 442, one end of the rotating shaft 443 is fixedly connected to a driving shaft 444, and the outer surface of one end of the driving shaft 444 is fixedly connected to a gear 445, the top of the T-shaped plate 41 is slidably connected to a toothed plate 446, the top of the T-shaped plate 41 is fixedly connected to a tension spring 447 for resetting and pulling the toothed plate 446 through a bracket, the outer surface of the driving shaft 444 is sleeved with an elastic clamping sleeve 448, and the elastic clamping sleeve 448 is fixedly connected to the U-shaped frame 42 through a bracket;

The upward movement of the U-shaped frame 42 can drive the rotating shaft 443 to move upward, and the upward movement of the rotating shaft 443 can drive the workpiece clamped by the electric clamp 45 to move upward. When the upward movement reaches a certain distance, the gear 445 contacts the teeth on the tooth plate 446. The continuous upward movement of the gear 445 can roll on the tooth plate 446, and then drive the rotating shaft 443 to rotate, so as to realize the flipping of the workpiece clamped by the electric clamp 45.

The downward movement of the U-shaped frame 42 can drive the rotating shaft 443 to move downward, and then drive the workpiece clamped by the electric clamp 45 to move downward. Since the rotating shaft 443 is connected to the fixed block 441 for one-way rotation through the one-way bearing 442, the gear 445 will not roll on the tooth plate 446 when it moves downward, thereby ensuring the stability of the workpiece after the flip adjustment. As the gear 445 moves downward, the teeth on the gear 445 squeeze the teeth on the tooth plate 446, and then one side of the tooth plate 446 can be driven to move and lose contact with the gear 445, and then the gear plate 446 can be orderly lowered for work.

The inner ring of the one-way bearing 442 is fixed to the outer surface of the rotating shaft 443, and the outer ring is fixed to the inside of the fixed block 441, forming a one-way rotation operation of the rotating shaft 443.

The tension spring 447 is set to reset and pull the tooth plate 446 so that when the rotating part 44 moves upward, it can form a flipping operation.

It is set up using the connection method and encoding method of the prior art, and is used to drive one of the pulleys 64 to rotate. The two pulleys 64 are connected through a belt drive, so that the other pulley 64 rotates synchronously, thereby driving the screw rod 61 to rotate forward and reverse, thereby realizing the synchronous movement of one side or the other of the two connecting frames 62.
