Description

A voice digital display vernier caliper

technical field

The invention specifically relates to a vernier caliper, in particular to a voice digital display vernier caliper. the

Background technique

Vernier calipers are often used in electronic PCB design or installation design of various workpieces to ensure the accuracy of the design package. Existing digital display vernier calipers need to remove the vernier caliper from the workpiece to read when measuring. However, once the digital display vernier caliper is separated from the workpiece to be measured, the measured data is easily changed due to the displacement of the caliper vernier, resulting in reading errors. the

Contents of the invention

The present invention aims at the deficiencies of the prior art, and provides a voice digital display vernier caliper which can digitally display and play data. the

In order to achieve the above object, the present invention adopts the following technical solutions, the present invention includes a scale body, a sliding block, a fixed arm beam and a moving arm beam; the scale body passes through the slide block; Fixing screws; the fixed arm beam is installed at the bottom of the scale body, and the movable arm beam is installed at the bottom of the slider; the top of the slider is also equipped with a voice player; the front of the slider is equipped with a voice key, a digital display key and display; the fixed arm beam and the movable arm beam are equipped with diameter sensors; the diameter sensor is connected to the controller through the A/D converter; the controller is respectively connected to the voice key, digital display key, display and voice playback device. the

Preferably, the fixed arm beam and the movable arm beam are installed on the same horizontal plane. the

Preferably, the display can be a digital tube or a liquid crystal screen. the

Beneficial effects of the present invention:

Press the digital display key, and the display can be connected to display the measurement data through the single-chip microcomputer; press the voice key, and the voice key can be connected to the voice player through the single-chip microcomputer, and the measured data can be broadcast; It can be measured in the workpiece that the measurer cannot reach; the measurer can obtain the measured data without moving the measuring tool during the measurement process, which can effectively avoid the measurement error caused by moving the measuring tool. the

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings. The following descriptions are only used to illustrate specific embodiments of the present invention, and do not limit the protection scope of the present invention. the

As shown in accompanying drawing 1 and accompanying drawing 2, the present invention comprises ruler body 1, sliding block 2, fixed arm beam 4 and movable arm beam 5; Described ruler body 1 passes through sliding block 2; Described sliding block 2 top is installed There are fixing screws 3 fixed to the ruler body 1; the fixed arm beam 4 is installed at the bottom of the ruler body 1, and the boom beam 5 is installed at the bottom of the sliding block 2; a voice player is also installed on the top of the sliding block 2 7; the front side of the sliding block 2 is equipped with a voice key 9, a digital display key 10 and a display 6; a diameter sensor 8 is installed on the fixed arm beam 4 and the moving arm beam 5, and the diameter sensor 8 passes through the fixed arm beam 4 and the moving arm beam. The distance that arm 5 beams draw apart judges the diameter size of measured workpiece; Described diameter sensor 8 is connected controller 11 by A/D converter, and the analog signal that measures is converted into digital signal and is given to controller 11 to process; Said control The device 11 is respectively connected to the voice key 7, the digital display key 10, the display 6 and the voice player 7; when the voice key 9 and the digital display key 10 are pressed, the controller 11 detects the key signal and performs corresponding operations. the

Wherein, the fixed arm beam 4 and the movable arm beam 5 are installed on the same horizontal plane; the display 6 can be a nixie tube or a liquid crystal screen. the

The present invention can display data and broadcast data, and can be used in an environment with poor light, and can also be used for measurement in workpieces that cannot be reached by the measurer's line of sight; during the measurement process, the measurer can obtain the measured data without moving the measuring tool, It can effectively avoid measurement errors caused by moving measurement tools. the

The foregoing embodiment is only an example of the present invention, and is not intended to limit the implementation and scope of rights of the present invention. All technical solutions identical or equivalent to those described in the claims of the present invention shall be included in the protection scope of the present invention. the
