Description

Technical Field

[0001] This application relates to the field of mechanical measurement technology, and in particular to a measuring device for machining the outer circle of a cylinder. Background Technology

[0002] In the field of machining, cylindrical outer diameter machining is a common manufacturing method for cutting the outer diameter of shaft parts. Shaft parts play a crucial role in many mechanical devices, and the accuracy of their cylindrical outer diameter parameters has a vital impact on the operating performance of the equipment.

[0003] Specifically, errors in the outer diameter of a cylinder directly affect the friction and wear of shaft parts, thus impacting equipment operating efficiency and energy consumption. Furthermore, the accuracy of the outer diameter parameter is crucial for the precision retention of shaft parts. Large errors can lead to a decline in precision over long-term use, affecting the machining accuracy and quality of the equipment. In addition, deviations in the outer diameter parameter negatively impact the service life of shaft parts, potentially causing premature failure and increasing maintenance costs and downtime. During equipment operation, the rigidity of shaft parts is critical for maintaining stable operation; inaccurate outer diameter parameters reduce rigidity, affecting normal equipment operation. Moreover, errors in the outer diameter parameter can also cause vibration and noise problems, affecting operational stability and the comfort of the working environment. Therefore, from the perspective of improving the performance of shaft products, accurate detection of the outer diameter parameter of the cylinder is essential.

[0004] In actual cylindrical outer diameter machining processes, although CNC machine tools can directly control the machined outer diameter, many factories still use conventional machine tools. When machining cylindrical outer diameters using conventional machine tools, to obtain the dimensions, the machining process needs to be paused, and then the outer diameter needs to be measured using a measuring tool. The machining parameters are then adjusted based on the measurement results before machining continues. This machining method has significant drawbacks. Because it requires repeated pauses for measurement, the machining efficiency is low, failing to meet the high-efficiency requirements of modern industrial production, and increasing production costs and time.

[0005] Therefore, there is still considerable room for improvement in the existing technology for detecting the outer diameter of cylindrical outer circles. A technical solution that can improve processing efficiency and accurately detect outer diameter parameters is needed to solve the above problems. Utility Model Content

[0007] This application provides a cylindrical outer circle machining measuring device, which includes a fixed support, a movable support, and a calibration mechanism. The movable support is mounted on the fixed support and can move longitudinally, and the calibration mechanism is mounted on the movable support and can move longitudinally.

[0009] Optionally, in the cylindrical outer circle machining measuring device of this application, the movable support includes a measuring base plate, an upper connecting plate disposed on the upper part of the measuring base plate, a lower connecting plate disposed on the lower part of the measuring base plate, a plurality of screws disposed on one side of the measuring base plate, and two slide rods vertically fixed between the upper connecting plate and the lower connecting plate.

[0011] Optionally, in the cylindrical outer circle machining measuring device of this application, a marking scale is vertically provided on the substrate, and the zero point of the marking scale is aligned with the center line of the side end face of the lower connecting plate.

[0012] Optionally, in the cylindrical outer circle machining measuring device of this application, a laser lamp is provided on the side end face of the lower connecting plate, and the light emitted by the laser lamp is horizontal with the lower connecting plate and aligned with the zero point of the marked scale.

[0013] Optionally, in the cylindrical outer circle machining measuring device of this application, the calibration mechanism includes a calibration slider and a calibration rod fixedly disposed on one side of the calibration slider.

[0017] The cylindrical outer circle machining measuring device of this application has the following beneficial technical effects:

[0018] 1. Improved Machining Efficiency: A movable support with adjustable height and markings is installed on the side of the machine tool chuck. After laterally aligning the zero point of the markings with the center point of the chuck, the cylinder to be measured is raised and lowered using a calibration rod support. The radius of the cylinder can be directly displayed through the scale lines. This allows operators to directly determine the dimensions of the cylinder during machining without disassembling it, significantly reducing measurement time and avoiding the low machining efficiency caused by repeated pauses for measurement. This effectively improves machining efficiency, shortens the production cycle, and reduces production costs.

[0019] 2. Improved Measurement Accuracy and Convenience: By horizontally embedding a laser lamp inside the lower connecting plate, the emitted light is parallel to the lower connecting plate. When adjusting the height of the measuring substrate, the light emitted by the laser lamp can serve as an auxiliary alignment tool, making it easier and more accurate to align the lower connecting plate (zero point) with the center point of the chuck laterally. This not only improves measurement accuracy and ensures the reliability of measurement results, but also simplifies the alignment operation, reduces operational difficulty, and makes the measurement process more convenient, further improving the efficiency and quality of the processing.

[0039] Figure 6 This is a fourth partial structural example diagram of the cylindrical outer circle machining measuring device according to an embodiment of this application, as shown below. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a guide wheel 37 is provided below the outer end of the calibration rod 32, and the bottom of the guide wheel 37 is at the same level as the measurement line 35.

[0040] Figure 7 This is a schematic diagram illustrating the application principle of the cylindrical outer diameter machining measuring device according to an embodiment of this application, such as... Figures 1 to 7 As shown, the cylindrical outer circle machining measuring device in this embodiment operates on the following principle:

[0041] In use, the back plate 12 is supported by the base plate 11 and placed on the side of the chuck 41 of the machine tool 4. First, adjust and ensure that the guide wheel 37 at the bottom of the calibration rod 32 is coplanar with the center point of the machine tool chuck 41. Before use, turn on the laser lamp 28 to emit horizontal light. Then, loosen the locking nut 26 on the screw 24 so that the measuring base plate 21 can be placed in the upward or downward sliding position at the front end of the back plate 11, so that the light is horizontally aligned with the center point of the chuck 41, thereby achieving the horizontal alignment of the lower connecting plate 23 (zero point of the scale) with the center point of the chuck 41. Then, tighten the locking nut 26 to lock the height of the measuring base plate 21. Each time the outer circle of the cylinder 5 to be measured on the chuck 41 is processed, first pull the calibration rod 32 and the calibration slider. The calibration rod 31 slides upward on the slide bar 25, and then the cylinder 5 to be measured is installed. The calibration rod 32 is supported on the upper surface of the cylinder 5 through the guide wheel 37 at its bottom. Then, the machine tool 4 performs cutting and other machining on the outer circle of the cylinder 5 from the side. During the rotation and machining of the cylinder 5, the calibration rod 32 is always supported above the cylinder 5 through the rotatable guide wheel 37. When the radius of the cylinder 5 is reduced by cutting, the calibration rod 32 and the calibration slider 31 will also lower together. Since the bottom height of the guide wheel 37 is aligned with the measuring line 35 on the observation through hole 34, combined with the scale number of the marking scale 27 and the auxiliary marking scale 36, the radius of the outer circle of the cylinder 5 to be measured is obtained, which can display the dimensional changes of the outer circle of the cylinder 5 to be measured in real time during the machining process.

[0042] In practical applications, the cylindrical outer circle machining measuring device of this embodiment, through comprehensive structural design, has the following beneficial technical effects:

[0043] 1. Improved Processing Efficiency: A movable bracket 2 with adjustable height and markings 27 is installed on the side of the chuck 41 of the machine tool 4. After laterally aligning the zero point of the markings 27 with the center point of the chuck 41, the cylinder 5 to be measured is supported by the calibration rod 32 and raised and lowered. The radius of the cylinder 5 can be directly displayed through the scale lines. This allows operators to directly determine the dimensions of the cylinder 5 during processing without removing it for measurement, significantly reducing measurement time and avoiding the low processing efficiency caused by repeated pauses for measurement. This effectively improves processing efficiency, shortens the production cycle, and reduces production costs.

[0044] 2. Improved Measurement Accuracy and Convenience: By horizontally embedding a laser lamp 28 inside the lower connecting plate 23, the emitted light is parallel to the lower connecting plate 23. When adjusting the height of the measuring base plate 21, the light emitted by the laser lamp 28 can serve as an auxiliary alignment tool, making it easier and more accurate to align the lower connecting plate 23 (zero point) with the center point of the chuck 41 laterally. This not only improves the measurement accuracy and ensures the reliability of the measurement results, but also simplifies the alignment operation, reduces the operational difficulty, and makes the measurement process more convenient, further improving the efficiency and quality of the processing.

Therefore, the scope of protection of this application should be determined by the scope of the claims.
