Description

Technical Field

[0001] The invention relates to the technical field of measurement, and in particular to a measuring device for calibrating a wedge-shaped feeler gauge. Background Art

[0002] The wedge-shaped feeler gauge is in the shape of a wedge with a wedge-shaped angle. There is a set of orderly scale marks and scale numbers on the scale surface. The scale numbers indicate the thickness of the corresponding mark position perpendicular to the measured base surface. According to the calibration specification JJF1584-2015 "Wedge-shaped Feeler Gauge", the wedge-shaped feeler gauge uses a pointed digital micrometer to measure on a flat plate through a table stand.

[0003] Referring to the Chinese invention patent, the publication number is: CN 109163632 B, and the name is: A measuring device for calibrating a wedge-shaped feeler gauge. The invention controls the up and down movement of the probe by a shift fork, and the positioning block is used to align the line. Under the action of the counterweight block, the measuring blade contacts the wedge surface of the feeler gauge, and the measured value is displayed on the display screen, so that the thickness of the wedge-shaped feeler gauge can be measured. The device has a simple structure, is easy to operate, can quickly align the line, and can measure accurately, which can reduce the workload of personnel and improve work efficiency.

[0004] However, in actual use, the above and similar technical solutions still have some problems:

[0005] 1. During the calibration of the wedge-shaped feeler gauge, when the dial indicator moves along the inclined surface of the wedge-shaped feeler gauge, the operator needs to continuously monitor the value changes on the display screen or the dial indicator. This process requires frequent comparison of the wedge-shaped feeler gauge's own scale and the dial indicator reading to evaluate the measurement error. This operation mode is not only cumbersome, but also increases the risk of human observation error and reduces measurement efficiency;

[0006] 2. After completing the test process, the current method fails to provide an intuitive means to instantly evaluate the error state of the wedge-shaped feeler gauge. It lacks an effective comparison reference mechanism or instant feedback system, making the interpretation and analysis of the test results complicated and not intuitive enough.

[0007] 3. When an error is found in the wedge-shaped feeler gauge, the current operation process does not include a clear step to mark the specific location or point of the error. This means that in the subsequent analysis or correction process, it is necessary to locate the error point based on data comparison one by one. This process is not only time-consuming and labor-intensive, but also reduces the efficiency of the overall inspection and calibration work and increases the complexity of the operation. Summary of the invention

[0008] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a measuring device for calibrating a wedge-shaped feeler gauge, which is convenient for recording and comparing the surface deviation of the wedge-shaped feeler gauge, can mark on the wedge-shaped feeler gauge, and quickly find the position.

The measuring device of the calibrated wedge-shaped feeler gauge has the needle tip of the contact needle in contact with the surface of the wedge-shaped feeler gauge, and the distance from the needle tip to the bottom of the placement groove corresponds to the scale, so that the height of the wedge-shaped feeler gauge at that point can be obtained by observing the distance the contact needle moves downward, and the value of the point on the wedge-shaped feeler gauge is read and compared with the value on the scale.

During the testing process, the laser head on the floating rod marks on the recording card and draws lines following the movement of the electronic micrometer. When the probe of the electronic micrometer detects the up and down movement of the concave and convex, it drives the floating rod to move up and down, thereby driving the laser head to move up and down, so that the laser head draws jagged lines on the recording card. By comparing with the scale lines on the recording card, the concave and convex value of the point on the wedge-shaped feeler gauge can be determined.

[0024] 3.

[0050] Embodiment 3:

[0051] Based on Example 2, Figure 7 , Figure 8 and Fig. 9, a measuring device for calibrating a wedge-shaped feeler gauge, the floating rod 55 is connected with a marking mechanism 9, the marking mechanism 9 includes a fixed block 91, the floating rod 55 is installed with a fixed block 91, the fixed block 91 is connected with an ink block 93 for graffiti on the wedge-shaped feeler gauge 6, the slider 48 is installed with an extrusion rod 94, the extrusion rod 94 is slidably connected with the fixed block 91, one end of the extrusion rod 94 is provided with a groove, a pair of air bags 98 are fixed inside the fixed block 91, the pair of air bags 98 are arranged inside the groove of the extrusion rod 94, a connected air pipe 97 is installed on the air bag 98, the end of the air pipe 97 is slidably connected with a piston rod 95, one end of the ink block 93 is installed on the piston rod 95, so that when the measuring needle of the electronic micrometer 43 detects the up and down movement of the concave and convex, the ink block 93 can be used to graffiti on the surface of the wedge-shaped feeler gauge 6, so as to facilitate the rapid finding of the concave and convex positions on the wedge-shaped feeler gauge 6.

[0052] In the present invention, a sliding block 92 is slidably connected to the fixed block 91, a third spring 99 is installed between the sliding block 92 and the fixed block 91, the ink block 93 is slidably connected to the sliding block 92, and a second spring 96 is installed between the ink block 93 and the sliding block 92, thereby ensuring stable sliding of the ink block 93.

[0053] Working principle: When calibrating the wedge-shaped feeler gauge 6, insert the wedge-shaped feeler gauge 6 into the placement slot 47, turn the second knob 7, the bottom end of the second knob 7 contacts the wedge-shaped feeler gauge 6, thereby limiting the movement of the wedge-shaped feeler gauge 6, turn the first knob 42, the first knob 42 drives the push rod 45 to move downward, thereby driving the contact needle 41 to move downward, the needle tip of the contact needle 41 contacts the surface of the wedge-shaped feeler gauge 6, and the distance from the needle tip to the bottom end of the placement slot 47 corresponds to the scale 44, so that the height of the wedge-shaped feeler gauge 6 at that point can be obtained by observing the downward distance of the contact needle 41, and by reading the value of the point on the wedge-shaped feeler gauge 6 and comparing it with the value on the scale 44, if the values ​​are consistent, it indicates that the wedge-shaped feeler gauge 6 is accurate at that point, and if the values ​​are different, it indicates that there is a problem at that point on the wedge-shaped feeler gauge 6 When a pair of push rods 45 slide, the two movable shafts 49 are driven to move, thereby adjusting the inclination of the fixed frame 46, so that the fixed frame 46 is parallel to the inclined surface of the wedge-shaped feeler gauge 6. The motor 83 is controlled to rotate by the button 3 and the host 2. The motor 83 drives the screw rod 81 to rotate, thereby driving the slider 48 to slide on the slide bar 82. The slide bar 82 is parallel to the surface of the wedge-shaped feeler gauge 6. The probe of the electronic micrometer 43 is in conflict with the surface of the wedge-shaped feeler gauge 6. When the slider 48 drives the electronic micrometer 43 to move, the probe moves on the surface of the wedge-shaped feeler gauge 6. When the inclined surface of the wedge-shaped feeler gauge 6 is uneven and an error occurs, the probe of the electronic micrometer 43 will move up and down, resulting in numerical fluctuations, which are recorded and displayed by the host 2, so as to facilitate the judgment of whether the wedge-shaped feeler gauge 6 is qualified;

[0054] Before testing the wedge-shaped feeler gauge 6, insert the recording card 52 into the plug plate 51, the plug plate 51 follows the deflection of the fixed frame 46, and the sliding rod 54 is driven to move when the slider 48 slides, that is, the sliding rod 54 drives the floating rod 55 and the electronic micrometer 43 to move synchronously. During the testing process, the laser head 56 on the floating rod 55 marks on the recording card 52 and draws lines following the movement of the electronic micrometer 43. When the probe of the electronic micrometer 43 detects the up and down movement of the concave and convex, it drives the floating rod 55 to move up and down, thereby driving the laser head 56 to move up and down, so that the laser head 56 draws uneven lines on the recording card 52. By comparing with the scale line 57 on the recording card 52, the concave and convex value of the point on the wedge-shaped feeler gauge 6 can be determined. After the measurement is completed, the recording card 52 can be pulled out, and the starting end of the line of the recording card 52 is aligned with the wedge-shaped feeler gauge 6. By observing the lines, the condition of the wedge-shaped feeler gauge 6 can be intuitively determined.

[0055] When the measuring needle of the electronic micrometer 43 detects the up and down movement of the concave and convex, it drives the fixed block 91 to move. The fixed block 91 makes the sliding block 92 close to the surface of the wedge-shaped feeler gauge 6 through the third spring 99, and the fixed block 91 and the extrusion rod 94 are displaced. The extrusion rod 94 will squeeze the two air bags 98 respectively, so that the gas inside the air bags 98 is injected into the air pipe 97, pushing the piston rod 95 to move, thereby pushing out the ink block 93. The second spring 96 is compressed, and the ink block 93 conflicts with the inclined surface of the wedge-shaped feeler gauge 6, thereby graffiti on the inclined surface of the wedge-shaped feeler gauge 6, so that it is convenient to quickly identify the unqualified position of the wedge-shaped feeler gauge 6 according to the ink dots on the wedge-shaped feeler gauge 6, so as to facilitate calibration.
