Description

Technical Field

[0001] The present invention relates to the technical field of instruments and meters, and in particular to an angle measuring instrument. Background Art

[0002] Angle measuring instruments are widely used. At present, they are used to measure the specified angles of large-scale mechanical equipment parts, tooling instruments and equipment, the angles between two planes formed by the installation positioning angles or the angle between a single plane relative to the horizontal plane. They can also be used to measure the angle perpendicular to the horizontal position or the parallelism between columns. They are mainly used in the on-site installation and commissioning of machine tools in the shipbuilding industry, aerospace machinery manufacturing, etc. High-precision angle measuring instruments include optical inclinometers, electronic inclinometers, etc., and the error range they can measure is relatively small.

[0003] The more advanced existing angle measuring instruments only need to place the device on the surface of the object to accurately measure the inclination angle of the bottom. A magnet is usually set at the bottom of this type of device, which can be adsorbed on the surface of the metal plate to be tested for inclination measurement. However, when measuring non-metallic material plates, the bottom magnet of the device loses its function and cannot fix the device on the surface of the plate to be measured. If the inclination angle of the non-metallic material plate is too large, the placed device is prone to slip, causing the bubble to shake and unable to be accurately centered or aligned, which in turn affects the correct measurement of the inclination angle and cannot be used for normal readings.

[0004] Therefore, in response to the above-mentioned existing angle measuring instruments, a method of using a magnet designed at the bottom to adsorb on the surface of the metal plate to be tested to measure the inclination angle results in that when measuring non-metallic material plates, the device cannot be properly fixed on the surface of the plate to be measured, and it is easy to slip. The bubble shaking cannot be accurately centered or aligned normally, which in turn affects the correct measurement of the inclination angle and cannot be used normally. The problem can be solved by designing an angle measuring instrument with a detachable mounting column, etc., which can keep the goniometer body part independent for use and can also be quickly assembled. After adjustment, the entire device can be fixed on the inclined surface of the material plate using a fixing splint in conjunction with the mounting column to complete stable fixation, thereby solving the problem of being unable to stabilize the goniometer body when encountering non-metallic material testing, thereby avoiding affecting the measurement results. Summary of the Invention

[0005] In order to overcome the problem that the existing angle measuring instruments use a bottom-designed magnet to adsorb on the surface of the metal plate to be tested for inclination measurement, when measuring non-metallic material plates, the device cannot be properly fixed on the surface of the plate to be measured, and it is easy to slip. The bubble shaking cannot be accurately centered or combined, which in turn affects the correct measurement of the inclination and cannot be used for normal readings.

The left end of the goniometer body 1 is rotatably connected to the column 4 via the damping rotating shaft. After the device is fixed to the material plate, the goniometer body 1 can be freely rotated vertically to adjust the display angle of the display 3 for convenient reading. The bottom of the column 4 is rotatably connected to the base 5 via the damping rotating shaft. After the device is fixed to the material plate, the goniometer body 1 can be freely rotated horizontally to adjust the display angle of the display 3 for convenient reading.

[0024] The goniometer body 1 in this device can adopt the electronic inclinometer model of Swiss WYLER. This device is an existing technology. The electronic inclinometer is to replace the optical reading system of the optical inclinometer with electronic measurement calculation and display. The core of the design is to use an absolute encoding digital angle measurement system to ensure measurement accuracy. It is composed of a light source, a code disk, a sensor, and a calculation circuit. The code disk is engraved with fixedly arranged light windows and dark windows. The widest light window is the fixed zero position of the code disk. The code disk is divided into M fixed sectors, representing different degree intervals, and the measured angle value is electronically subdivided to obtain accuracy to a single degree. The angular value of the second is obtained by using two sets of light sources and sensors, which are respectively arranged at the 180° radial position of the code disk. The two sets of collected data of the code disk are read and calculated at the same time, which can reduce the error by 1 / 2, greatly improving the measurement error of the instrument. The external display screen will present the angular value processed by the microcomputer in the format of 271°32′57″ on the display screen, and the operator can read it directly. The display screen displays the time and date at the same time as the angular value, enriching the display content. Therefore, the working principle of the device is the existing technology, and this application will not elaborate on this detection process.

[0025] During operation, when encountering a non-metallic material plate with a large inclination angle, first insert the connecting column 22 into the circular through-hole 21 in the base 5 and the magnetic plate 6, and rotate the bidirectional screw 28 by the knob 3 29 to control the two movable plates 24 to move relatively close, drive the two arc-shaped clamping blocks 25 to clamp the connecting column 22, and at the same time, insert the locking column 26 into the lock hole 27 to complete the fixation, and then rotate the threaded rod 2 19 by the knob 2 20, and the lifting plate 18 controls the rectangular hollow plate 12 to move downward from between the two L-shaped connecting plates 11. Then, the bottom of the mounting post 7 is brought into contact with the inclined surface of the material plate and the threaded rod 15 is rotated by the knob 16. The lifting block 13 controls the upward movement of the fixing clamp 14 and the mounting post 7 to fix the entire device on the inclined surface of the material plate to achieve a stable fixation. Finally, the goniometer body 1 is rotated horizontally and vertically by the knob 20 to adjust its viewing angle. After the combined image bubble portion 2 is stabilized, the detected inclination angle data displayed on the display 3 can be read.

[0026] Through the above steps, by providing a detachable mounting post 7 and the like, the goniometer body 1 can be partially used independently while also being quickly assembled. After adjustment, the entire device can be secured to the inclined surface of the material plate using the fixing clamp 14 in conjunction with the mounting post 7, achieving stable fixation. This solves the problem of the goniometer body 1 being unable to stabilize when testing non-metallic materials, preventing it from sliding on the inclined surface of the material, which would cause the image bubble portion 2 to shake and prevent accurate centering or alignment. This allows the device to perform normal inclination measurement and readings, is easy to use, and improves the flexibility and wide applicability of the device, thereby solving the above-mentioned technical problems.
