Description

Technical Field

[0001] This utility model relates to the field of photoelectric measurement technology, specifically to a diameter measuring instrument swing measuring device. Background Technology

[0002] A laser diameter gauge is a device that uses laser light to scan the object being measured and convert it into a usable output signal to measure the size of the object, based on the geometric principles of optics. It is widely used for measuring the size of various materials such as wires, cables, wire rods, enameled wires, optical fibers, rubber, plastics, wires, rods, pipes, and rolled steel.

[0003] However, when measuring flat wires with a laser rangefinder, the width and thickness of the flat wire cannot be made to be exactly perpendicular to the light curtain during the placement process. This requires the separate manufacture of special guide wheels suitable for the specifications of the flat wire, as well as the adjustment of the light curtain and the tooling to make the width and thickness perpendicular. The whole process is difficult to adjust and has high manufacturing costs. Summary of the Invention

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Unless otherwise specified, the technical means used in the implementation examples are conventional means well known to those skilled in the art.

[0023] refer to Figures 1-2 This utility model discloses a diameter gauge swing measuring device, including a vertically arranged mounting plate 1. A diameter gauge 2 is rotatably mounted on one side of the mounting plate 1. Guide wheels 3 are respectively arranged on both sides of the mounting plate 1. The guide wheels 3 correspond to the measuring area of ​​the diameter gauge 2. The object to be measured is placed on the guide wheels 3, passing through the measuring area of ​​the diameter gauge 2 through one guide wheel 3 and placed on the other guide wheel 3. A crank mechanism is provided on the mounting plate 1 to drive the diameter gauge 2 to rotate. The crank mechanism drives the diameter gauge to rotate, so that the light curtain is perpendicular to the object to be measured (such as a flat wire), thereby enabling the diameter gauge to collect the width and thickness of the object to be measured.

[0024] Furthermore, a rotating central shaft 4 is provided on the side of the diameter gauge 2 opposite to the mounting plate 1. The shaft hole of the rotating central shaft 4 corresponds to the measuring area of ​​the diameter gauge 2. One end of the rotating central shaft 4 passes through the mounting plate 1 and rotates relative to the mounting plate 1. It should be noted that the rotating central shaft has a through-hole, allowing the object to be measured to pass through the rotating central shaft into the measuring area of ​​the diameter gauge, or to pass through the diameter gauge and exit from the rotating central shaft, while the object passes through the two guide wheels. Figure 1 As shown. Meanwhile, the rotating central shaft and the mounting plate can be fixed together by bearings; that is, the bearings are sleeved and fixed on the rotating central shaft, and the bearings pass through the mounting plate for fixation.

[0025] Furthermore, to increase the stability of the mounting plate, the bottom of the mounting plate 1 is provided with a base plate 5 perpendicular to it, the guide wheel 3 is provided on the support rod 6, and the support rod 6 is fixed on the base plate 5, or the support rod 6 is L-shaped and fixed on the mounting plate 1.

[0026] Furthermore, a fixing plate 7 is provided at one end of the rotating central shaft 4 that passes through the mounting plate 1. The fixing plate 7 has a through hole 8 coaxial with the rotating central shaft 4. One end of the fixing plate 7 is fixed to the base plate 5. Alternatively, the fixing plate 7 is L-shaped, with one end fixed to the mounting plate 1. The shape and installation of the support rod and fixing plate can be set according to actual needs, such as... Figure 2As shown, it can be fixed to the base plate, or its function can be achieved by setting the fixing plate and support rod into an L-shape and fixing the other end to the mounting plate.

[0027] Furthermore, the crank mechanism includes a motor 18, with a crank disc 9 fixedly mounted on the output end of the motor 18. A connecting rod 10 is rotatably connected to the crank disc 9, and a fixed shaft 11 is rotatably connected to the other end of the connecting rod 10. The fixed shaft is perpendicular to the connecting rod, and the other end of the fixed shaft 11 passes through the mounting plate 1 and is fixed to the L-shaped support frame 12 on which the diameter measuring instrument 2 is placed, i.e., fixed to the side wall corresponding to the vertical plate of the support frame and the mounting plate. The hole on the mounting plate 1 through which the fixed shaft 11 passes is an arc-shaped hole. The connecting rod and the crank disc are eccentrically positioned. The motor drives the connecting rod to rotate, thereby causing the other end of the connecting rod to move along the arc-shaped hole, causing the diameter measuring instrument to swing around the central axis of rotation, thereby adjusting the position of the diameter measuring instrument and making the light curtain on the diameter measuring instrument perpendicular to the object being measured.

[0028] Furthermore, in one embodiment, the motor 18 is mounted on the mounting plate 1 and on the same side as the diameter gauge 2, with the output end of the motor 18 passing through the mounting plate 1 and connected to the crankshaft disc 9. The connecting rod is parallel to the mounting plate.

[0029] Furthermore, the mounting plate 1 is equipped with a power supply 13 and a controller 14. The power supply 13 is connected to both the diameter gauge 2 and the controller 14. The controller 14 is connected to a display 15, and an alarm light 16 is connected to the display 15. The diameter gauge 2 is connected to the controller 14. The controller controls the motor's start-up and rotation angle. The data measured by the diameter gauge is displayed on the display. When the thickness or width of the measured object exceeds the tolerance value, an alarm is triggered.

[0030] Furthermore, the motor 18 is connected to the power supply 13, or to an external power supply. The display 15 can be fixed to the base plate 5 by the upright 17. The shape and size of the mounting plate of this utility model are not fixed and can be set as needed. At the same time, for aesthetic purposes, the mounting plate can be used as a side plate, and a shell can be set on the side where the power supply and other components are set to enclose all the components and form a box, with only the guide wheels exposed.

[0031] When using this invention, the object to be measured simply needs to be inserted into the rotating central shaft through the guide wheel, pass through the diameter gauge, and then through another guide wheel. The angle of the diameter gauge's swing is then controlled by a motor to ensure that the diameter gauge's light curtain is perpendicular to the object. The measuring device disclosed in this invention is compatible with various sizes of objects, has a simple structure, low cost, high integration, and facilitates data acquisition and interaction.
