Description

Technical Field

[0001] This utility model belongs to the field of length measurement and testing technology, and relates to an integrated length measuring device. Background Technology

[0002] In the production process of substrate glass, the removal inspection is a crucial step in ensuring product quality. Precise measurement of position height, glass-spacer offset, and glass loading offset is particularly important. Currently, these parameters are mainly measured using a ruler, with the measurement data manually read from the ruler's scale. However, this traditional measurement method has many problems. From the perspective of error sources, it includes both systematic errors and human errors. Systematic errors may include deviations in perpendicularity, deformation of the measuring ruler, and displacement of calibration points; human errors manifest in the difficulty of ensuring the consistency of measurement readings and subjective differences in the judgment of horizontality and perpendicularity. In practical measurement work, due to changes in external conditions, limitations in instrument performance, and differences in the observer's skill level, even when measuring the same object several times, the results often differ, and discrepancies between observed values ​​and their theoretical values ​​are inevitable. For traditional visual measurement, the existence of errors is even more unavoidable. Specifically in stadia measurement, reading errors, measurement errors caused by inaccurate perpendicularity when the two rulers are manually in contact, and errors caused by the tilt of the stadia ruler all have a significant negative impact on measurement accuracy. This method, which relies on manual visual inspection and traditional measuring tools, lacks advanced technology and equipment support, directly resulting in a complex and inefficient measurement process with low accuracy, making it difficult to meet the high-quality measurement requirements of substrate glass production. Utility Model Content

[0003] The purpose of this invention is to solve the technical problem that length measuring instruments in the prior art rely on visual measurement, resulting in low measurement accuracy, and to provide an integrated length measuring device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides an integrated length measuring device, including a height gauge and a vernier caliper; The vernier caliper is connected to the vertical height gauge; the height gauge is equipped with a height gauge vernier, which is slidably sleeved on the height gauge; a rotating wheel is provided on the height gauge vernier, and the movement of the height gauge vernier is controlled by the rotating wheel; a height gauge measuring end is provided at one end of the height gauge vernier near the vernier caliper; a height gauge display screen is provided on the height gauge vernier for displaying height data.

[0005] Furthermore, the height gauge vernier is equipped with a height gauge button for converting between relative and absolute measurement values.

[0006] Furthermore, the vernier caliper is equipped with a dual-caliper measuring end.

[0007] Furthermore, the dual-card measuring end is connected to a vernier caliper display screen.

[0008] Furthermore, the vernier caliper display screen is equipped with a serial interface.

[0009] Furthermore, the height gauge is a single-column structure.

[0010] Furthermore, the vernier caliper is welded onto the height gauge.

[0011] Furthermore, a horizontal bracket is provided at the bottom of the height gauge.

[0012] Furthermore, a caliper is provided at the lower part of the height gauge.

[0013] Furthermore, the height gauge display screen is equipped with a serial interface.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This utility model discloses an integrated length measuring device. By vertically fixing a vernier caliper to a height gauge to form a spatial rigid reference, it completely eliminates the measurement reference drift caused by assembly gaps in split tools. The height gauge vernier is slidably sleeved on the height gauge column and is precisely vertically driven by a rotating wheel, improving the contact positioning accuracy of the height gauge measuring end to ±0.01mm. The measuring end is located at the end of the vernier caliper near the vernier caliper, ensuring that the height measurement and the horizontal measurement reference are spatially consistent. The height gauge display screen is integrated into the vernier body to provide real-time feedback of height data, directly avoiding errors from manual secondary readings, and ultimately achieving high-precision and rapid traceability of spatial dimensions by a single person and a single machine.

[0015] Furthermore, by adding a height gauge button to the height gauge vernier, the device further realizes one-click measurement reference switching: the operator does not need to reset the zero point or perform manual calculations, but can directly press the button to instantly switch the raw data collected by the height gauge measuring end between relative measurement value (the difference based on any point) and absolute measurement value (the absolute value based on the device zero point), completely eliminating the risk of cumulative errors caused by the complexity of mode switching operations in traditional equipment; the measurement mode switching process does not interrupt data acquisition, so that a single height measurement action can simultaneously meet the dual needs of process dimension comparison and absolute coordinate positioning, significantly improving measurement efficiency and data reliability under complex working conditions.

[0016] Furthermore, the dual-jaw measuring end configuration allows the device to simultaneously measure inner diameter, depth, and step dimensions while retaining the basic outer diameter measurement function of the vernier caliper. The rigid, one-piece molding design of the dual jaws eliminates the assembly gap of traditional movable jaws, keeping the repeatability error of horizontal measurement within ±0.01mm. Combined with the vertical fixed connection between the vernier caliper and the height gauge, the spatial position of the dual-jaw measuring end and the height gauge measuring end form a permanent orthogonal reference, enabling the acquisition of all parameters of the internal and external dimensions and height dimensions of complex workpieces in a single clamping, completely avoiding the cumulative error of reference conversion caused by multiple positioning of separate tools.

[0017] Furthermore, the direct connection between the caliper display screen and the dual-caliper measuring end creates a physical-level data closed loop for measurement and display. When the dual-caliper measuring end contacts the object being measured in the horizontal direction, the measurement data is transmitted to the display screen in real time through the built-in sensor, completely eliminating the display lag error caused by signal delay or mechanical transmission in traditional split instruments. The operator can read the real-time data on the display screen synchronously without leaving the measurement point, avoiding caliper offset or accidental touch caused by switching eyes, thus improving the operational stability of horizontal dimension measurement and achieving synchronization between measurement action and data capture.

[0018] Furthermore, the combined configuration of the horizontal bracket and the caliper creates an all-condition adaptive support system for the device: the horizontal bracket ensures a permanent reference plane when the device is placed on the ground through precision machining of the bottom surface, completely eliminating tilting errors caused by uneven support surfaces; the caliper is integrated into the lower part of the height gauge and achieves rigid anchoring of the device on production line guide rails, irregularly shaped workpieces, or vibration platforms through a mechanical locking mechanism, resisting external disturbances; the two can be seamlessly switched according to the working conditions, solving the problem of on-site measurement failure caused by the single fixing method of traditional measuring equipment.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings: See Figure 1 This invention provides an integrated length measuring device, including a height gauge 3 and a vernier caliper 1, wherein the vernier caliper 1 is welded and fixed perpendicularly to the column of the height gauge 3. The height gauge 3 adopts a single-column structure, with a height gauge vernier 8 slidably sleeved on its column. This vernier caliper achieves precise vertical movement via a top rotating wheel 10. A height gauge measuring end 4 is provided at the end of the height gauge vernier caliper 8 near the vernier caliper 1. A height gauge display screen 7 is integrated on the front of the vernier caliper body for real-time display of height measurement values, and a height gauge button 6 is also provided to switch between relative and absolute measurement modes. The vernier caliper 1 is equipped with a dual-clamp measuring end 2 for horizontal dimension measurement, and the measured value is displayed on the vernier caliper display screen 9 located on the vernier caliper body. This display screen is equipped with a serial interface for data output. A horizontal bracket can be optionally installed on the bottom base of the height gauge 3 to enhance placement stability, or a clamp 5 can be installed at the bottom to adapt to the clamping requirements of complex working conditions. The height gauge display screen 7 also has a serial interface to realize dual data output channels, ensuring efficient recording and analysis of measurement information.

[0029] The working principle of this utility model is as follows: This utility model relates to an integrated length measuring device that achieves synchronous dimensional measurement through a vertically welded structure between a height gauge 3 and a vernier caliper 1. When measuring height, the operator rotates the wheel 10 of the vernier caliper 8, driving the vernier to slide vertically along the single column of the height gauge 3, so that the measuring end 4 of the height gauge contacts the upper surface of the object being measured. At this time, the height gauge display screen 7 displays the Y-axis height value in real time, and the relative or absolute measurement mode can be switched via the height gauge button 6. When measuring horizontal distance, the operator horizontally stretches the double-clamp measuring end 2 of the vernier caliper 1, causing its inner measuring claws to fit against the two sides of the object being measured. The vernier caliper display screen 9 simultaneously outputs the X-axis distance data. The two measurement processes are independent and do not interfere with each other: the vertical movement of the height gauge vernier 8 and the horizontal extension and retraction of the vernier caliper 1 are orthogonally decoupled in space, and the rigid welded connection ensures a unified measurement reference. Measurement data can be output to external devices through the built-in serial interfaces of the height gauge display 7 and the vernier caliper display 9, respectively. The bottom horizontal bracket or caliper 5 provides stable support under multiple working conditions, ultimately achieving rapid and accurate acquisition of spatial point coordinates.

[0030] This utility model is an integrated length measuring device. The device achieves rigid unification of a three-dimensional spatial reference through a vertically welded structure between the height gauge 3 and the vernier caliper 1, completely eliminating the assembly accumulation errors of traditional split measuring tools. The precision drive of the rotating wheel 10 of the height gauge vernier 8 and the horizontal extension and retraction of the dual-clamp measuring ends 2 of the vernier caliper 1 form spatial orthogonal motion decoupling, ensuring that the synchronous measurement of height and horizontal distance does not interfere with each other and improving operational efficiency by more than 200%. Dual independent digital display systems (height gauge display 7 / vernier caliper display 9) combined with a serial interface enable real-time output of measurement data coordinates, avoiding errors from manual recording. The multi-condition adaptability design of the bottom horizontal bracket and caliper 5 significantly enhances the device's vibration resistance stability in complex environments, controlling measurement repeatability errors within ±0.01mm. The one-button switching function of the height gauge button 6 greatly simplifies the process parameter matching process, ultimately achieving a revolutionary breakthrough in single-person multi-process measurement efficiency and spatial dimension traceability accuracy in fields such as mechanical manufacturing and precision assembly.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
