Description

Technical Field

[0001] The utility model relates to the technical field of diameter measuring instruments, in particular to a diameter measuring instrument for steel bar building materials. Background Technique

[0002] A diameter measuring instrument is a precision instrument used to measure the diameter of an object, and it can measure the diameter information of various workpieces or materials online or offline.

[0003] When common steel bar building materials are produced, it is necessary to measure the diameter. Generally, the steel bar is placed in the measuring device, and the measuring plate is moved along the surface of the scale. When the measuring plate contacts the surface of the steel bar, the diameter of the steel bar can be measured.

[0004] However, since the whole steel bar is cylindrical, when the measuring plate contacts the surface of the steel bar, the steel bar will be extruded, and the steel bar will roll due to the extrusion, resulting in the measuring plate being easily separated from the surface of the steel bar, and the diameter of the steel bar cannot be accurately measured. Content of the Utility Model

[0028] Installation plates 4 are arranged on both sides of the surface of the guide rod 3. The thread directions on both sides of the surface of the guide rod 3 are opposite. Please refer to Figure 4 , the installation plates 4 are both screwed to both sides of the surface of the guide rod 3, and positioning plates 5 are provided above the installation plates 4;

[0029] Please refer to Figure 1 , an installation frame 6 is arranged at the rear part of the upper surface of the base 1. A driving machine 7 is installed on the lower surface of the top plate of the installation frame 6. Please refer to Figure 2 , a driving rod 8 is coaxially installed on the rotor of the driving machine 7. A lifting plate 9 is screwed to the surface of the driving rod 8, and a measuring rod 10 is installed at the bottom end of the lifting plate 9;

[0030] Pointers 11 are arranged on both sides of the lifting plate 9, and scale lines 12 are engraved on both sides of the front surface of the installation frame 6;

[0031] Put the steel bar between the positioning plates 5. Starting the motor 2 can drive the guide rod 3 to rotate, and then can drive the installation plates 4 to move. Moreover, the thread directions on both sides of the surface of the guide rod 3 are opposite, so that the positioning plates 5 can be driven to move relatively, and the two sides of the steel bar can be squeezed to prevent the steel bar from shaking during measurement. Starting the driving machine 7 can drive the driving rod 8 to rotate, thereby driving the lifting plate 9 to lift, and then driving the measuring rod 10 to move downward to contact the upper surface of the steel bar. At this time, the pointer 11 will also move upward along the surface of the scale line 12. According to the scale pointed by the pointer 11, the diameter of the steel bar can be measured.

[0032] The bottom of the scale line 12 is the initial scale. The pointer 11 contacts the surface of the scale line 12. When the pointer 11 moves upward, the contact position with the scale line 12 will also change, so as to measure the diameter of the steel bar.

[0033] Please refer to Figure 1 , on the upper surface of the base 1 at the corresponding position of the driving rod 8, there is an installation table 13. Please refer to Figure 2 , the bottom end of the driving rod 8 is connected to the surface of the installation table 13 through a bearing. The installation table 13 is used to raise the height of the driving rod 8, so that when the lifting plate 9 moves to the lowest position, the bottom end of the measuring rod 10 can contact the surface of the base 1. When a steel bar is placed below the measuring rod 10, the measuring rod 10 will contact the surface of the steel bar, and then the diameter of the steel bar can be measured.

[0034] On the back of the lifting plate 9, there is a lifting block 14. A lifting groove 15 is longitudinally opened on the surface of the mounting frame 6. The lifting block 14 is embedded in the lifting groove 15, which can limit the lifting plate 9, so that the lifting plate 9 can move vertically.

[0035] Please refer to Figure 4 , on both sides of the upper surface of the mounting plate 4, there are mounting blocks 16. The upper surfaces of the mounting blocks 16 are connected to the bottom of the positioning plate 5, so that the positioning plate 5 can move along with the mounting plate 4.

[0036] Please refer to Figure 3 , on both sides of the upper surface of the base 1, there are mounting grooves 17. The mounting blocks 16 are inserted into the interior of the mounting grooves 17. The mounting blocks 16 and the mounting grooves 17 enable the mounting plate 4 to move linearly.

[0037] The working process of this device is as follows: First, place the steel bar between the positioning plates 5. Starting the motor 2 can drive the guide rod 3 to rotate, and then drive the mounting plate 4 to move. Then, the thread directions on both sides of the surface of the guide rod 3 are opposite, so as to drive the positioning plates 5 to move relative to each other, and can squeeze both sides of the steel bar to prevent the steel bar from shaking during measurement. Finally, starting the drive motor 7 can drive the driving rod 8 to rotate, so as to drive the lifting plate 9 to rise and fall, and then drive the measuring rod 10 to move downward to contact the upper surface of the steel bar. At this time, the pointer 11 will also move upward along the surface of the scale line 12. According to the scale pointed by the pointer 11, the diameter of the steel bar can be measured.
