Description

multifunctional digital display angle ruler

technical field

The utility model relates to a measuring instrument, in particular to an angle ruler.

Background technique

In the woodworking sawing machine widely used by people at present, the angle of the saw blade relative to the workbench is marked by engraved lines. There is a main engraved line on the turntable where the saw blade sits. The table has a series of angular reticles with a resolution of 1°. Align the main engraved line on the turntable where the saw blade is located with the angle engraved line on the workbench to read the relative angle of the saw blade to the workbench. The angles measured in this way are very rough, resulting in inaccurate processed angles.

Utility model content

Aiming at the problems existing in the prior art, the purpose of this utility model is to overcome the above-mentioned shortcomings and provide a multifunctional digital display angle ruler with more convenient, accurate and time-saving reading.

The technical solution adopted by the utility model to solve the technical problems is: a multifunctional digital display angle ruler, which includes a display device with a control chip, two measuring arms, a connecting shaft is fixed on one measuring arm, two measuring The arms are connected and relatively moved through the connecting shaft, on which a capacitive angle sensor B is fixed, and on the measuring arm that moves relative to it, a capacitive angle sensor A is fixed, and the capacitive angle sensor A is set on the Below the display device, control buttons are arranged on the display device.

In the multifunctional digital display angle ruler, the two measuring arms are respectively the long measuring arm arranged on the upper part and the short measuring arm arranged on the lower part, and the connecting shaft is fixed on the short measuring arm. A capacitive angle sensor A is fixed on the long measuring arm, the display device is arranged on the long measuring arm, and the capacitive angle sensor A is arranged below the display device.

In the multifunctional digital display angle ruler, the two measuring arms are respectively the long measuring arm arranged on the upper part and the short measuring arm arranged on the lower part, and the connecting rotating shaft is fixed on the long measuring arm. A capacitive angle sensor A is fixed on the short measuring arm, the display device is arranged on the short measuring arm, and the capacitive angle sensor A is arranged below the display device.

The multifunctional digital display angle ruler is provided with a boss at the bottom of the short measuring arm.

In the multifunctional digital display angle ruler, the boss is integrated with the short measuring arm.

In the multifunctional digital display angle ruler, the boss is an accessory fixed on the bottom of the short measuring arm.

The utility model installs the capacitive angle sensor B on the connecting shaft because the two measuring arms can move relatively, and installs the capacitive angle sensor A on a measuring arm that moves relative to the connecting shaft. Due to the relative movement of the two measuring arms , so that the capacitive angle sensors A and B also rotate relative to each other, and the relative rotation angle can be displayed on the display device, and the button can realize the functions of starting, shutting down, clearing any position, and locking the value of the liquid crystal display. Because the utility model adopts a high-precision angular displacement sensor, its resolution is greatly improved, and the angle between the saw blade and the worktable can be adjusted to a very accurate position by using the instrument, so that the reading is more convenient, accurate and time-saving.

Detailed ways

As shown in Figure 1, the utility model multi-functional digital display angle ruler comprises a liquid crystal display 1 with a control chip, a button 2, a capacitive angle sensor A3 a capacitive angle sensor B4, a connecting shaft 5, and a measuring long arm 6, Measuring the short arm 7, the measuring long arm 6 is arranged on the top of the measuring short arm 7, the connecting shaft 5 is fixed on the measuring short arm 7, the measuring short arm 7 and the measuring long arm 6 are connected together through the connecting shaft 5, and can rotate relatively, A capacitive angle sensor B4 is fixed on the connection shaft 5, and a capacitive angle sensor A3 is fixed on the measuring long arm 6. The capacitive angle sensor A3 and the capacitive angle sensor B4 can rotate relatively, and the key 2 is arranged on the liquid crystal display 1. , the liquid crystal display 1 is installed and fixed on the measuring long arm 6 , and the capacitive angle sensor A is arranged at the bottom of the liquid crystal display 1 and connected with the liquid crystal display 1 . When the long measuring arm 6 rotates relative to the capacitive angle sensor A3 and the capacitive angle sensor B4 connected to the rotating shaft 5 , the relative rotation angle can be displayed on the liquid crystal display 1 . Button 2 can realize the functions of power on, power off, reset at any position, and lock the value of the LCD display. A boss 8 is provided at the bottom of the short measuring arm 7, and the boss 8 can be integrated with the short measuring arm 7, or can be installed and fixed on the short measuring arm 7 as a separate accessory.

As shown in Figure 2, when in use, the long measuring arm 6 of the multi-functional digital display angle ruler is placed close to the baffle plate 11 of the woodworking sawing machine, and the boss 8 on the lower side of the measuring short arm of the multi-function digital display angle ruler is snapped into the rotatable round table of the sawing machine 12 in the groove. Use a square to zero the multifunctional digital display angle ruler. In this way, when the turntable of the sawing machine rotates through an angle around the workbench, this angle is the angle at which the long arm 6 is measured and the short arm 7 is rotated relative to each other. This angle is displayed on the liquid crystal display 1 .

Because the multifunctional digital display angle ruler of the utility model adopts a high-precision angular displacement sensor, its resolution can reach 0.05°. The angle between the saw blade and the table can be adjusted to a very precise position using this instrument. It has the advantages of convenient, accurate and time-saving reading.
