Description

Technical Field

[0001] The utility model relates to the technical field of metrological verification and calibration devices, in particular to a high-precision metrological verification and calibration device. Background Art

[0002] In the field of metrological verification and calibration technology, high-precision metrological verification and calibration equipment is the key equipment to ensure measurement accuracy and reliability.

[0003] Referring to the existing authorized announcement number CN217465970U of "a high-precision metrology verification and calibration device", it can clamp the measured object to prevent the object from shaking during the measurement process. At the same time, it can measure the height of the object, which is convenient for height recording, easy to operate, and has the advantages of strong practicality. It solves the problem that in the process of measuring objects on the existing platform scale, the object is placed on the scale surface with poor stability and cannot be directly fixed on the scale. At the same time, when measuring the height of the object on the scale, the scale surface drops due to the gravity of the object, resulting in inaccurate height measurement, and when measuring the height, it cannot be compared with the reference starting point, and direct observation with the naked eye will also result in certain errors. Therefore, a high-precision metrology verification and calibration device is proposed.

[0004] At the same time, the existing "a high-precision metrology verification and calibration mechanism" with authorized announcement number CN220490206U can effectively prevent the object from shaking during weighing through the setting of the clamping mechanism and the guide mechanism, thereby effectively ensuring the accuracy of the scale's measurement of the object's height change. It solves the problem that during the existing scale's measurement of objects, the object is prone to slide and tilt on the scale surface due to the lack of a certain fixing mechanism on the scale, thereby affecting the accuracy of the scale's measurement of the object's height change.

[0005] In actual application, the above existing patent can only realize the height calibration of the object to be calibrated. When the width calibration of the object to be calibrated is required, the object to be calibrated can only be placed on its side for calibration, which is cumbersome to operate and does not have the function of performing height calibration and width calibration at the same time.

[0006] Therefore, the utility model proposes a high-precision metrology verification and calibration equipment to solve the above problems.

The top of the support box 1 is symmetrically fixed with two support plates 32 based on the support plate 3 as the center, and a pull rod 33 is slidably installed on the two support plates 32. A clamping plate 34 is fixedly installed at one end of the two pull rods 33 close to each other, and the clamping plate 34 is in damping sliding contact with the top side of the support plate 3. The same damping spring 35 is fixedly installed between the clamping plate 34 and the support plate 32, and the damping spring 35 is movably sleeved on the outside of the pull rod 33, which is convenient for clamping and fixing the object to be calibrated placed on the support plate 3, so as to ensure that there will be no problem when measuring height and width. The two ends of the two pull rods 33 that are away from each other are fixedly installed with handles 36, and the two handles 36 are respectively located on the sides of the two support plates 32 that are away from each other, which is convenient for operating the pull rods 33, so that it is convenient for the operator to quickly control the clamping plate 34 to quickly clamp and fix the object to be measured and calibrated. Slide blocks 4 are slidably installed on the inner walls of the front and rear sides of the support frame 11, and two guide rods 41 that are arranged parallel to each other are fixedly installed on the side where the two slide blocks 4 are close to each other. Two mounting plates 42 are slidably installed on the two guide rods 41, and two support rollers 45 are rotatably installed on the corresponding mounting plates 42, and the two support rollers 45 are mutually They are arranged in parallel, and the electric cylinder 2 44 and the scale bar 2 43 are both fixedly mounted on the mounting plate 42 on the rear side. The working end of the electric cylinder 2 44 is fixedly connected to the mounting plate 42 on the front side, and the scale bar 2 43 is slidably connected to the mounting plate 42 on the front side, so as to control the spacing between the two mounting plates 42, thereby controlling the contact between the two support rollers 45 and the object to be calibrated, thereby facilitating the rapid measurement and reading of the width value of the object to be measured.

The two toothed plates 5 are both meshed with the gear 51, so that the mounting support roller 45 can move upward when the electric cylinder 1 21 controls the top plate 2 to move downward.

[0030] In this embodiment, in order to enable the support plate 3 to maintain good stability during operation, annular grooves are provided on the mutually adjacent sides of the support plate 3 and the support box 1, and a plurality of balls are rotatably installed in the two annular grooves.

[0031] In this embodiment, in order to enable the slider 4 to maintain stable sliding on the inner wall of the support frame 11 and effectively avoid the tilting of the support roller 45, guide grooves are opened on the front and rear inner walls of the support frame 11, the cross-section of the slider 4 is convex, and the slider 4 is in sliding contact with the corresponding inner wall of the guide groove.

[0032] Working principle: First, turn on the power, and the operator controls the pull rod 33 and the clamp 34 to move away from the center position of the support plate 3 by pulling the handle 36, and places the object to be measured and calibrated in the center position on the support plate 3, and then releases the handle 36. Under the action of the damping spring 35, the clamp 34 can stably clamp and fix it, thereby preventing the object from shaking during the measurement process and affecting the measurement accuracy. Then, the operator controls the servo motor 31 to work and rotate the support plate 3, so as to facilitate the operator to perform all-round measurement operations on the object.

[0033] When measuring the height, the operator controls the electric cylinder 1 21 to move the top plate 2 downward. The top plate 2 drives the slider 4 and the mounting plate 42 on the rear side to move upward through the transmission action of the toothed plate 5 and the gear 51. During the descent of the top plate 2, the electric cylinder 2 44 adjusts the distance between the two mounting plates 42 to keep the two support rollers 45 in contact with the calibration object to be measured. As the top plate 2 moves downward continuously, the reading on the scale bar 2 43 is read in real time, so that the change in the width of the calibration object can be measured from bottom to top in real time. When the top plate 2 contacts the top side of the object to be calibrated, the electric cylinder 1 21 is closed and the top plate 2 is moved downward. The height and width readings can be taken respectively on the scale bar 12 and the scale bar 2 43. When it is necessary to measure and calibrate the width of the object to be calibrated in different directions, the pull rod 33 is pulled by the handle 36 to make the clamp 34 break contact with the object to be calibrated and the support plate 3 is controlled by the servo motor 31 to deflect. After the object to be calibrated is adjusted to the required direction, the handle 36 is released so that the clamp 34 clamps and fixes it again, and then the distance between the two mounting plates 42 is controlled by the electric cylinder 2 44 to operate the two support rollers 45 to measure and calibrate the width of the object to be calibrated and read the readings on the scale bar 2 43.

[0034] Through this device, operators can conveniently and quickly perform height and width measurement and calibration operations on the objects to be measured and calibrated, which improves the practicability and measurement accuracy of the equipment. At the same time, the device has a simple structure and is easy to operate. It is suitable for various environments and usage scenarios and has broad application prospects.
