[0001] The utility model relates to the technical field of laser diameter gauges, and particularly relates to a guide wheel bracket assembly of a laser diameter gauge. Background Art

[0002] Laser diameter gauges can be used for on-line diameter measurement and are widely used in the enameled wire (round wire, flat wire) industry, wire and cable, optical fiber cable industry, aluminum-plastic composite pipe (plastic pipe) industry, copper strip and steel strip production equipment industry, hardware precision machining and tool and die detection industry, micro-fine wire drawing industry, iron and steel metallurgy industry, 3D printing consumables industry, and industries for measuring the width and thickness of various circular and flat objects.

[0003] A guide wheel bracket assembly is arranged on the laser diameter gauge for placing a workpiece to be measured during the conveying process. The existing guide wheel bracket assembly includes a bracket arranged on the laser diameter gauge body, two connecting shafts arranged on the bracket, and two guide wheels respectively installed on the connecting shafts through bearings.

[0004] In order to cooperate with workpieces to be measured with different diameters for measurement, it is usually necessary to make the height of the guide wheel adjustable so that the workpiece to be measured can be located in the middle of the measurement area when placed on the two guide wheels. The existing connecting shafts are usually locked and fixed with screws, resulting in inconvenient operation for adjusting the height of the connecting shafts, and thus inconvenient operation for driving the adjustment of the height of the guide wheels. Content of the Utility Model

[0005] The purpose of the utility model is to provide a guide wheel bracket assembly of a laser diameter gauge, which has the functions of facilitating the disassembly and assembly of the connecting shaft and the guide wheel and adjusting the height of the guide wheel.

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Embodiment 1: A guide wheel bracket assembly of a laser diameter measuring instrument, such as Figure 1 and Figure 2 As shown, it includes a bracket 1 for being set on the laser diameter meter, two connecting shafts 2 set on the bracket 1, and two guide wheels 3 rotatably connected to the connecting shafts 2.

[0023] like Figure 2 and Figure 3As shown in the figure, the cross-section of the bracket 1 is in a "U" shape. On both sides of the bracket 1 corresponding to the measurement areas of the laser diameter gauge, there are "U"-shaped notches 11. On both sides of the two ends of the bracket 1, a plurality of connection holes 12 for installing the connecting shaft 2 are symmetrically arranged. The plurality of connection holes 12 at one end of the bracket 1 extend obliquely upward towards the middle of the bracket 1. The guide wheel 3 is provided with a central hole 31. At both ends of the guide wheel 3, there are mounting grooves 32 communicating with the central hole 31. Bearings 4 are arranged in the mounting grooves 32. The guide wheel 3 is made of ceramic material. The outer diameter of the connecting shaft 2 matches the inner diameter of the connection hole 12. The connecting shaft 2 is fitted with the inner rings of the two bearings 4. At both ends of the connecting shaft 2, there are annular clamping grooves 21 located outside the bracket 1. Elastic retaining rings 5 for restricting the movement of the connecting shaft 2 are arranged on the annular clamping grooves 21.

[0024] Implementation effect: The two ends of the connecting shaft 2 are fixed by the elastic retaining ring 5, replacing the traditional screw fixing method, which has the function of being convenient for disassembly and assembly; and the guide wheel 3 is made of ceramic material, so that the workpiece to be measured will not be damaged when passing through; at the same time, the plurality of connection holes 12 at one end of the bracket 1 extend obliquely upward towards the middle of the bracket 1. At this time, by installing the connecting shaft 2 on the connection holes 12 at different positions, the installation height of the guide wheel 3 can be adjusted to adapt to the measurement of workpieces to be measured with different diameters; in addition, when measuring a workpiece to be measured with a larger diameter, as the installation height of the guide wheel 3 decreases, the distance between the two guide wheels 3 increases, making the workpiece to be measured more stable when placed.

[0025] Example 2: A guide wheel bracket assembly of a laser diameter gauge, as Figure 3 and Figure 4 shown. The difference from Example 1 is that the bracket 1 includes a first frame body 13 for installing on the laser diameter gauge, a second frame body 14 telescopically arranged on the first frame body 13, and an elastic fixing component 15 arranged between the first frame body 13 and the second frame body 14 to fix the second frame body 14. The two notches 11 are respectively arranged on the first frame body 13 and the second frame body 14. A plurality of connection holes 12 are respectively arranged at the two ends of the first frame body 13 and the second frame body 14.

[0026] As Figure 4 shown, there are two elastic fixing components 15. The two elastic fixing components 15 are respectively arranged at the two ends of the first frame body 13 and the second frame body 14. After the elastic fixing components 15 are installed, they do not interfere with the guide wheel 3 installed on any connection hole 12. The elastic fixing component 15 includes a guide shaft 151 arranged on the second frame body 14 and passing through the first frame body 13, a compression spring 152 sleeved on the part of the guide shaft 151 passing through the first frame body 13, and a limit end cover 153 arranged on the guide shaft 151 to prevent the compression spring 152 from falling off.

[0027] As Figure 4As shown, the lower surface height of the second frame 14 is higher than the lower surface height of the first frame 13, and the lower surface of the second frame 14 away from the first frame 13 is provided with a plurality of hemispherical protrusions 141, and the lowest point height of the protrusions 141 is the same as the lower surface height of the first frame 13.

[0028] Implementation effect: When the installation height of the guide wheel 3 needs to be adjusted, after removing the elastic retaining ring 5, the second frame 14 moves in the direction away from the first frame 13 by overcoming the action of the elastic fixing assembly 15. At this time, the combination of the connecting shaft 2, the guide wheel 3 and the bearing 4 can be directly removed and directly installed in the connecting hole 12 to be adjusted, which has the effect of conveniently adjusting the installation height of the guide wheel 3. When a force away from the first frame 13 is applied to the second frame 14, the compression spring 152 is compressed, so that the second frame 14 can move in the direction away from the first frame 13; at the same time, when the second frame 14 is released, the compression spring 152 is reset and drives the second frame 14 to reset; at the same time, the setting of the guide shaft 151 can limit the extension and contraction of the second frame 14. There are two elastic fixing assemblies 15, which are respectively arranged at the two ends of the first frame 13 and the second frame 14, which can ensure the stability of the first frame 13 and the second frame 14 when they are extended and contracted; at the same time, interference with the guide wheel 3 installed on any one of the connecting holes 12 can be avoided. By making the lower surface height of the second frame 14 higher than the lower surface height of the first frame 13 , the friction force when the second frame 14 is extended and retracted relative to the first frame 13 is reduced, and the setting of the protrusion 141 can be placed on a laser diameter gauge to ensure the stability of the second frame 14 .

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
