Description

Technical Field

[0001] The present application relates to the field of micrometer detection, and in particular to a micrometer detection device. Background Art

[0002] The micrometer is a high-precision, high-resolution measuring tool that can accurately measure the length, width, height and other dimensional parameters of the workpiece. It is often used to check the workpiece processing quality and dimensional control to ensure that the product meets strict tolerance standards. The micrometer is mainly used to check the shape and position errors of the workpiece, such as roundness, flatness, verticality, circular runout, etc. Through the contact between the probe and the workpiece surface, the micrometer can detect the slight difference in the workpiece surface, so as to determine whether its shape and position meet the requirements. In the manufacturing and assembly process, the micrometer is also often used for the precise alignment of the workpiece. By measuring the distance difference between the workpiece and the reference surface, the micrometer can help workers achieve accurate positioning and alignment, and improve assembly accuracy.

[0003] Micrometers are widely used in manufacturing quality control, equipment maintenance and calibration, materials science and mechanics research, etc. In the process of precision parts processing and assembly, micrometers are used to detect geometric parameters such as part size, concentricity, flatness, verticality, etc.

[0004] When a dial indicator is damaged, the measuring mechanism inside it may be affected, resulting in inaccurate readings. A damaged dial indicator may still be able to display readings in some cases, but these readings may be wrong or unreliable. For example, a damaged dial indicator may display a reading of 0 even if the actual measured verticality is not 0, thus misleading the operator. Utility Model Content

[0017] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0018] The present application provides a micrometer detection device, comprising a base 1, a slide 2, a column 3 and a gauge block 4 with at least two known standard values, wherein the slide 2 is mounted on the column 3, the slide 2 is used to mount the micrometer, the column 3 is mounted on the base 1, the gauge block 4 is arranged on one side of the slide 2, the slide 2 can drive the micrometer to perform lifting motion along the column 3, measure at least two known standard values ​​of the gauge block 4 in turn, record the reading of the micrometer, and compare it with the known standard value of the gauge block 4.

[0019] The present application provides a micrometer detection device, which ensures the high accuracy of the micrometer in verticality measurement through a precise calibration process. The device includes a base 1, a slide 2, a column 3 and at least two gauge blocks 4 with known standard values. The slide 2 is mounted on the column 3 for mounting the micrometer, and can be raised and lowered along the column 3 by a driving mechanism. The column 3 is firmly mounted on the base 1 to provide stable support for the entire device. The gauge block 4 is arranged on one side of the slide 2 to facilitate measurement by the micrometer.

[0020] In the design of the gauge block 4, we use two types of side surfaces: the first vertical side surface 41 is a completely vertical surface, indicating the standard value of "0 to 0", that is, no offset or error; while the second vertical side surface 42 has a known verticality error, such as "0 to 5" indicating that the side surface has a verticality error of 5 units (the specific unit depends on the measurement unit of the micrometer, such as millimeters, micrometers, etc.). This design allows us to simulate measurements under different verticality conditions, so as to fully evaluate the performance of the micrometer.

[0021] The calibration process is as follows: First, mount the dial indicator on slide 2 and move it to a completely vertical gauge block 4 (i.e., "0 to 0" gauge block 4). At this time, record the reading of the dial indicator and compare it with 0 to ensure the accuracy of the dial indicator in a completely vertical state. Next, move the dial indicator to a gauge block 4 with a known verticality error (i.e., "0 to 5" gauge block 4) and record the reading at this time. Compare this reading with the known verticality error (5 units) to evaluate the accuracy of the dial indicator when measuring non-perfectly vertical objects.

[0022] This calibration method allows us to more accurately evaluate the measurement performance of the dial gauge. Using two gauge blocks with different verticality characteristics4 can provide more comprehensive calibration data compared to a single standard value. This helps to identify potential problems in the verticality measurement of the dial gauge and perform calibration or repair in a timely manner to ensure the accuracy and reliability of its measurement results.

[0023] In summary, the micrometer detection device provided by the present application effectively improves the accuracy and performance of the micrometer in verticality measurement through a precise calibration process and a variety of gauge block 4 designs. This device is of great significance to the industrial field requiring high-precision measurement.

[0024] In this embodiment, the gauge block 4 includes a first vertical side surface 41 and a second vertical side surface 42 . The first vertical side surface 41 is a completely vertical surface, and the second vertical side surface 42 is a surface with a known verticality error.

[0025] By providing two sides with different verticality characteristics, this gauge block 4 can fully test the performance of the dial gauge in verticality measurement. The first vertical side 41 is used to calibrate the zero position or reference position of the dial gauge to ensure its accuracy in a completely vertical state; while the second vertical side 42 is used to simulate a non-perfect vertical situation to test the measurement ability of the dial gauge in the presence of verticality errors.

[0026] Since the second vertical side surface 42 has a known verticality error, the user can accurately evaluate the error range of the dial gauge when measuring verticality. By comparing the reading of the dial gauge on the second vertical side surface 42 with the known verticality error, the user can accurately understand the measurement performance of the dial gauge under non-perfect vertical conditions and perform corresponding calibration and adjustment.

[0027] By using two different sides on the same gauge block 4 for calibration, the user can complete a comprehensive calibration process without replacing multiple gauge blocks 4. This greatly simplifies the calibration process, reduces operational complexity, and improves calibration efficiency.

[0028] The gauge block 4 with two sides with different characteristics can meet different calibration requirements. The user can choose to use a completely vertical side or a side with a vertical error for calibration according to the needs to meet different measurement accuracy and requirements.

[0029] By comparing the readings of the dial gauge on the completely vertical and the side with errors, the user can more intuitively understand the performance of the dial gauge when measuring verticality. This intuitiveness helps the user better understand the measurement principle and working mechanism of the dial gauge and improve their understanding and application of the calibration results.

[0030] In this embodiment, a guide column 5 is further provided on one side of the column 3. The guide column 5 is vertically mounted on the base 1 and connected to the slide 2 via a slider. The vertical installation of the guide column 5 and the connection with the slider of the slide 2 ensure the stability of the slide 2 during the lifting process. This design reduces the shaking and deviation of the slide 2 during movement, thereby improving the stability and accuracy of the micrometer during the measurement process.

[0031] In this embodiment, a handle 6 is provided on the side of the base 1. The handle 6 provides a convenient holding point for the user, making it easier to move or reposition the entire dial gauge detection device. Whether moving from a storage location to a working location or moving between different working areas, the handle 6 greatly simplifies the transportation process.
