Description

Technical Field

[0001] This invention relates to the field of laser measurement technology, specifically to a laser measuring instrument for measuring the dimensional tolerances of machined workpieces. Background Technology

[0002] Laser measurement, simply put, is a technique that uses a laser beam as an "electronic ruler" or "optical probe" to accurately determine the geometric or kinematic parameters of a target object, such as distance, displacement, velocity, shape, and vibration, by detecting the changes in physical quantities between its emission and reception.

[0003] A search revealed a Chinese patent with application number "CN202511713024.6", which specifically describes a laser measuring instrument for the dimensions of metal after forming. The instrument includes a housing, with a connecting block connected to the upper part of one side of the housing, a fixed frame connected to one side of the connecting block, and support frames connected to the lower ends of the fixed frames. Conveyor belts are connected to both sides of the inner wall of the fixed frames. A laser measuring mechanism is connected to one side of the upper end of the housing, and a centering mechanism is connected to one side of the lower end of the fixed frames. The centering mechanism includes four sets of connecting rods, with the upper ends of the connecting rods connected to the lower sides of the fixed frames. A support plate is connected to the lower ends of the connecting rods, and a moving mechanism is connected to the upper sides of the support plate.

[0004] In the machining field, flanges are critical connecting components, and their dimensional accuracy directly affects the assembly quality and operational reliability of equipment. Currently, laser measurement technology, due to its advantages of non-contact operation, high precision, and high efficiency, has been widely used in flange dimensional inspection. However, in actual measurement operations, the flange surface often has residual metal shavings, coolant stains, and environmental dust adhering to it. These contaminants can scatter or block the laser beam, leading to measurement data deviations and seriously affecting the authenticity and consistency of the test results. Because laser measurement requires a high degree of cleanliness of the optical path, if the flange surface is not thoroughly cleaned before measurement, it is easy to cause repeated measurement errors and misjudgments, thereby reducing quality control efficiency and product qualification rate.

[0005] Therefore, this invention proposes a laser measuring instrument for the external dimensional tolerances of machined workpieces to solve the aforementioned problems. Summary of the Invention

When measuring the size of the flange, the workpiece is conveyed by the conveyor belt 2. When the workpiece is conveyed to the bottom of the mounting frame 3, the dust on the surface of the workpiece is cleaned by the processing unit 6 and the surface cleaning unit 7.

A cleaning roller 744 is fixedly connected to the middle of the rotating rod 743. A motor 612 and an air pump 613 are fixedly connected to the upper side of the mounting plate 63. A conveying pipe 614 is fixedly connected to the outer side of the air pump 613 and communicates with the rotating tube 641.

The lower end of the rotating tube 641 is fixedly connected to the lifting cylinder 642. The outer side of the lifting cylinder 642 is provided with a central cleaning component 65, a connecting component 66 and a blowing component 68. When cleaning the dust on the flange surface, the hydraulic cylinder 4 drives the lifting plate 5 to descend, and the lifting plate 5 drives the cleaning roller 2 744 to descend (at this time, the cleaning roller 2 744 is in contact with the workpiece). At this time, the motor 612 is started, the motor 612 drives the rotating shaft 644 to rotate, the rotating shaft 644 drives gear component 2 645 to rotate, gear component 2 645 drives gear component 1 643 to rotate, gear component 1 643 drives the rotating tube 641 to rotate, the rotating tube 641 drives the fixed plate 71 to rotate, the fixed plate 71 drives the base plate 73 to rotate, and the base plate 73 drives the cleaning roller 2 744 to rotate, so that the cleaning roller 2 744 can clean the dust on the workpiece surface.

When cleaning dust, the lifting cylinder 642 is controlled to descend, which in turn drives the base plate 666 to descend, bringing the base plate 666 into contact with the conveyor belt 2. The lifting cylinder 642 is then controlled to descend further. The base rod 665 on the chassis 666 rises relative to the lifting cylinder 642. The base rod 665 drives the control disc 664 to rise, which in turn drives the inclined plate 662 to rotate. The inclined plate 662 drives the extension plate 654 to move. Due to the symmetrical distribution of the inclined plates 662 on both sides, the extension plates 654 on both sides separate from each other. The extension plates 654 drive the connecting frame 655 to move, which in turn drives the cleaning roller 656 to move.

Then, the rotating tube 641 rotates, and the rotating tube 641 carries... The rotating cleaning roller 656 facilitates the cleaning of dust from the inner wall of the workpiece hole. A gap exists between the gear ring 651 and the gear component 652, allowing the gear component 652 to mesh with the gear ring 651 when the cleaning roller 656 contacts the inner wall of the hole. As the cleaning roller 656 rotates, the gear component 652 on the rotating rod 653 on the connecting frame 655 also rotates. Under the action of the gear ring 651, the gear component 652 rotates, driving the cleaning roller 656 on the rotating rod 653 to rotate, further improving the cleaning effect of dust inside the workpiece hole.

[0031] Simultaneously, under the action of rotating rod 653, gear 652, and gear ring 651, the cleaning roller 656 is controlled to rotate, further improving the cleaning of dust in the hole. At the same time, the chassis 666 drives the upright 669 to rise, and the upright 669 drives the lifting plate 792 to rise. Under the action of rotating block 799, control plate 798, rocker plate 795, control plate 797, and upright plate 791, the cleaning roller 744 is lowered to contact the workpiece surface. The linkage component 75 increases the rotation of the cleaning roller 744, increasing the cleaning effect.
