Description

Technical Field

[0001] This invention relates to the field of zero-position instrument technology, and more particularly to a digital photoelectric projection zero-position instrument. Background Technology

[0002] With the continuous advancement of optoelectronic technology, such as the emergence of high-resolution photodetectors, high-performance light sources, and advanced optical imaging systems, a technological foundation has been provided for the development of digital optoelectronic projection null meters. Photodetectors can quickly and accurately convert light signals into electrical signals, thereby achieving precise capture and digital processing of projected images. High-resolution photodetectors can distinguish finer image details and improve measurement accuracy.

[0003] In many fields such as machining, aerospace, and precision instrument manufacturing, the requirements for measuring the dimensional accuracy, shape accuracy, and positional accuracy of parts are extremely high. Traditional measurement methods, such as calipers and micrometers, can meet basic measurement needs to a certain extent, but they often suffer from insufficient measurement accuracy, low efficiency, and complex operation when measuring complex-shaped parts, minute dimensions, and high-precision positional measurements.

[0004] Existing testing equipment typically has a measurement range of no more than 130 mm while ensuring high accuracy. It cannot perform a complete measurement of larger objects in one go. To measure large objects, multiple measurements must be taken and the data stitched together, which may introduce additional errors. These errors can also affect subsequent processes and steps, causing unnecessary trouble. Summary of the Invention

[0005] Given that the measurement range is typically no more than 130 mm while ensuring high accuracy, it is impossible to perform a complete measurement of larger objects in one go. If a large object needs to be measured, it is necessary to take multiple measurements and then stitch the data together. This may introduce additional errors, which will affect subsequent processes and steps, thus causing unnecessary trouble. Therefore, this invention is proposed.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] Reference Figure 1-4 The first embodiment of the present invention provides a digital photoelectric projection zero-position instrument, including: an instrument mounting base 1 and an arc-shaped mounting sleeve 2. A mounting rod is provided on the upper surface of the instrument mounting base 1, and an arc-shaped mounting sleeve 2 is provided on the vertical surface of the mounting rod. A display screen is provided on the arc surface outside the arc-shaped mounting sleeve 2. An instrument body 3 is mounted on the inner ring of the arc-shaped mounting sleeve 2. A detection structure 4 is provided on the upper surface of the instrument mounting base 1. The detection structure 4 includes: a U-shaped mounting plate 5. A T-shaped loading block 6 is provided on the inner ring of the U-shaped mounting plate 5. A drive motor 7 is mounted on the vertical surface outside the T-shaped loading block 6. A pair of rectangular moving slots 8 are formed on the upper surface of the T-shaped loading block 6.

[0029] One of the rectangular moving slots 8 has a threaded rod 9 inside, and a guide rod is also provided inside the rectangular moving slot 8. The threaded rod 9 is connected to the output end of the drive motor 7, and a pair of T-shaped moving blocks 10 are fitted on the rod body of the threaded rod 9 and the guide rod.

[0030] A rectangular limiting rod 11 is provided on the upper surface of each T-shaped moving block 10. A U-shaped storage sleeve 12 is also provided on the upper surface of the rectangular limiting rod 11. A cylindrical guide rod is also provided inside the U-shaped storage sleeve 12. A memory spring 13 is also provided on the short vertical surface inside the U-shaped storage sleeve 12. One end of the memory spring 13 is connected to the U-shaped storage sleeve 12, and the other end of the memory spring 13 is connected to the trapezoidal moving block.

[0031] The T-shaped moving block 10, which is away from the rectangular limiting rod 11, is provided with an L-shaped fixing rod 14 on its upper surface. The L-shaped fixing rod 14 and the trapezoidal moving block are provided with rectangular clamping plates 15 on their vertical surfaces. The rectangular clamping plates 15 are provided with protective layers on their vertical surfaces. The T-shaped loading block 6 is also provided with a rectangular support plate 16 on its upper surface. The rectangular moving groove 8 is also provided with a rectangular limiting plate 17 on its vertical surface.

[0032] When using, first manually pull the U-shaped handle on the inclined surface of the trapezoidal moving block. As the U-shaped handle is pulled, a pair of memory springs 13 will retract. Because the rectangular moving groove 8 is also equipped with a guide rod, a pair of T-shaped moving blocks 10 are fitted on the threaded rod 9 and the guide rod. The T-shaped moving blocks 10 away from the rectangular limit rod 11 are equipped with L-shaped fixing rods 14 on their upper surfaces. The vertical surfaces of the L-shaped fixing rods 14 and the trapezoidal moving blocks are equipped with rectangular clamping plates 15. The vertical surfaces of the rectangular clamping plates 15 are equipped with protective layers. So after pulling the U-shaped handle, you can directly place the material to be measured on the rectangular support plate 16. Note: When placing the material, one side of the material should be in contact with the rectangular clamping plate 15 away from the memory springs 13.

[0033] After placement, release the handle. Without any obstruction, a pair of memory springs 13 will rebound, clamping the material. Once clamped, simply start the instrument body 3 to collect data on the first half of the material. Then, the drive motor 7 will start. Since the output end of the drive motor 7 is connected to the threaded rod 9, several T-shaped moving blocks 10 will move as the drive motor 7 rotates. The distance they move will be the length of the rectangular support plate 16. After that, the drive motor 7 will stop, and the instrument body 3 will collect and merge the data to obtain the most accurate statistics. Then, the drive motor 7 will reverse, causing the T-shaped moving blocks 10 to reset.

[0034] Example 2

[0035] Reference Figure 1 , 2 5. This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a detection lens is also provided on the lower surface of the instrument body 3, an arc-shaped protective sleeve 18 is also provided on the lower surface of the instrument body 3, several corresponding holes are also provided on the lower surface of the arc-shaped protective sleeve 18, and an arc-shaped transparent shell 19 is provided at the lower end of the cross section of the several corresponding holes. Rectangular mounting strips 20 are provided on both sides of the arc-shaped protective sleeve 18, and temporary fixing holes are provided through the bottom surface of a pair of rectangular mounting strips 20. Temporary fixing rods 21 are rotatably connected to the rectangular mounting strips 20, and torsion bars 22 are provided on the lower surface of the temporary fixing rods 21.

[0036] After prolonged use of the device, dust will accumulate on the curved surface of the outer arc-shaped protective cover 18. This dust will affect data detection. To clean it, first twist several torsion bars 22 to remove the temporary fixing rods 21 set on the torsion bars 22. After twisting them off, simply remove the arc-shaped protective cover 18 and wipe off the dust. After wiping, carefully check whether there are scratches or continued dust adhesion on the several arc-shaped transparent shells 19 on the arc-shaped protective cover 18. If scratches appear on the arc-shaped transparent shells 19, a new arc-shaped protective cover 18 needs to be replaced. Then, install the new arc-shaped protective cover 18.

[0037] The remaining structure is the same as that in Example 1.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
