Description

Technical Field

[0001] This utility model relates to the technical field of verticality measuring equipment, specifically to a verticality measuring instrument with positioning and adsorption. Background Technology

[0002] In fields such as machinery manufacturing, construction, and aerospace, perpendicularity is a key indicator for measuring the geometric accuracy of objects, which directly affects product performance and engineering quality. With the development of industrial intelligence, higher requirements are placed on the automation, portability, and adaptability of measuring equipment, and the shortcomings of existing technologies urgently need to be overcome.

[0003] Currently, commonly used perpendicularity measuring equipment in the industry mainly includes traditional right-angle rulers, dial indicator combinations, coordinate measuring machines, and dedicated perpendicularity checkers. Existing measuring instruments mostly use a single-drive system. While pure electric drive enables rapid movement, its accuracy is insufficient for small displacement adjustments, making it difficult to meet high-precision measurement requirements. Pure manual drive is inefficient, cumbersome, and labor-intensive for measuring the full height of large workpieces. Furthermore, the position adjustment of the measuring stylus is limited, with a narrow adjustment range and poor versatility.

[0004] Therefore, this invention proposes a verticality measuring instrument for positioning and adsorption to solve the above-mentioned problems. Utility Model Content

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0025] like Figure 1-5As shown, a verticality measuring instrument with positioning and adsorption includes a base 1, a measuring column 6, and a positioning and adsorption assembly. The measuring column 6 is connected to the upper end of the base 1. A dovetail-shaped groove 13 is formed on the inner side of the measuring column 6. A sliding seat 4 is slidably connected in the dovetail-shaped groove 13. A corrugated tube 17 is sleeved between the sliding seat 4 and the measuring column 6. A lead screw 5 passes through the middle of the sliding seat 4 and is threadedly connected to the sliding seat 4. The two ends of the lead screw 5 are rotatably connected to the upper and lower ends of the measuring column 6, respectively. A dual-drive assembly is connected to the bottom of the measuring column 6 and is disposed in the base 1. The dual-drive assembly includes a first drive motor 7 and a manual crank 8. The output shaft of the first drive motor 7 is coaxially connected to the lead screw 5. The manual crank 8 is connected to the lead screw 5 through a bevel gear assembly 9 and is slidably connected to the base 1.

[0026] Furthermore, the sliding seat 4 is connected to a measuring stylus 16 via a vertical adjustment assembly. The vertical adjustment assembly includes a first connecting rod 10 and a second connecting rod 11. The first connecting rod 10 is fixedly connected to the sliding seat 4, and the second connecting rod 11 is slidably connected to the first connecting rod 10 and fixed by a locking bolt 15. A fine-tuning seat 14 is also connected to the end of the second connecting rod 11 away from the first connecting rod 10. The fine-tuning seat 14 is slidably connected to the second connecting rod 11, and the measuring stylus 16 is connected to the fine-tuning seat 14. A linear guide rail 12 is connected to the inner side of the first connecting rod 10 along the sliding direction of the second connecting rod 11, and a sliding groove 13 is formed on the second connecting rod 11 corresponding to the first connecting rod 10.

[0027] Furthermore, the positioning and adsorption assembly is connected to the base 1. The positioning and adsorption assembly includes a three-jaw chuck 18 and a second drive motor 19. The second drive motor 19 is coaxially connected to the bottom of the three-jaw chuck 18 via a reducer and is fixed inside the base 1. An adsorption positioning block 20 is connected to the middle of the three-jaw chuck 18. The adsorption positioning block 20 has multiple adsorption grooves 21 evenly distributed on it. The adsorption positioning block 20 has a threaded hole 22 axially distributed on it. A screw 23 is threaded into the threaded hole 22. A handwheel 24 is connected to the upper end of the screw 23, and a pressing plate 25 is connected to the lower end. An elastic sheet 26 is connected to the lower end of the pressing plate 25. A strip-shaped deformation groove is distributed in the middle of the elastic sheet 26, and the deformation groove is arranged along the length direction of the elastic sheet 26.

[0028] Furthermore, each of the four corners of the lower end face of the base 1 is threaded with a horizontal adjusting bolt 27, and the lower end of the horizontal adjusting bolt 27 is connected with a rubber pad 28. A level 2 is embedded in the upper end face of the base 1, and the level 2 is arranged parallel to the upper end face of the base 1.

[0029] The working process of this utility model is as follows:

[0030] First, the instrument is leveled. Observe the level indicator 2 on the upper surface of the base 1. Adjust the level of the base 1 by rotating the leveling bolts 27 at the four corners of the lower end of the base 1. During the rotation, the rubber pads 28 rise and fall synchronously with the bolts to ensure the base 1 is placed stably until the level indicator 2 shows that the base 1 is in a horizontal position. This completes the level calibration of the measurement benchmark and provides a basis for subsequent measurement accuracy. Then, place the workpiece to be measured on the three-jaw chuck 18 for positioning and fixing. Rotate the handwheel 24 above the adsorption positioning block 20 to drive the screw 23 to move downward along the threaded hole 22, causing the lower pressing plate 25 to press down synchronously. The pressing plate 25 pushes the elastic sheet 26 to contact the workpiece surface. The strip deformation groove in the middle of the elastic sheet 26 deforms adaptively with the pressure, increasing the fit with the workpiece and further fixing the workpiece through mechanical pressure. If the workpiece surface is flat, the adsorption groove 21 on the adsorption positioning block 20 can help enhance the fit stability and prevent the workpiece from loosening during measurement. Then, based on the height and position of the part of the workpiece to be measured, the position of the measuring stylus 16 is adjusted. The locking bolt 15 between the first connecting rod 10 and the second connecting rod 11 is loosened, and the second connecting rod 11 is slid along the linear guide rail 12 to make a coarse adjustment of the stylus height. After adjusting it to roughly correspond to the area of ​​the workpiece to be measured, the locking bolt 15 is tightened to fix it. The fine adjustment seat 14 is slid along the second connecting rod 11 to make a fine positioning of the measuring stylus 16, ensuring that the tip of the stylus is aligned with the vertical side of the workpiece to be measured, thus completing the precise alignment of the measurement point.

[0031] For vertical plane measurements, the sliding seat 4 drives the measuring stylus 16 to move along the workpiece height direction to measure perpendicularity. If electric drive is used, the first drive motor 7 is started, and the motor output shaft directly drives the lead screw 5 to rotate. The lead screw 5 is threadedly connected to the sliding seat 4, and the sliding seat 4 slides smoothly up and down along the dovetail groove 13 of the measuring column 6. The bellows 17 extends and retracts with the sliding seat 4 to prevent dust from entering the sliding groove 13. If manual fine-tuning is required, the manual crank 8 is pushed, which drives the lead screw 5 to rotate through the bevel gear assembly 9, achieving slow movement of the sliding seat 4. During the movement of the sliding seat 4, the measuring stylus 16 remains in contact with the measured surface of the workpiece, and the offset of the stylus at different heights is recorded as the basic data for perpendicularity calculation.

[0032] If it is necessary to measure the perpendicularity of the workpiece in the entire circumference, start the second drive motor 19 to drive the three-jaw chuck 18 and the workpiece to rotate slowly.
