Description

Technical Field

[0001] This utility model belongs to the field of metal detection technology, specifically relating to a device for measuring the surface roughness of metal wire. Background Technology

[0002] Surface roughness of metal wires refers to the characteristic of minute spacing and unevenness of the wire surface. This unevenness is formed during drawing, heat treatment, storage, or subsequent processing, and is a microscopic geometric error. Surface roughness has a crucial impact on the mechanical properties, fatigue life, corrosion resistance, coating quality, friction and wear, and electrical contact performance of metal wires.

[0003] When measuring the surface roughness of metal wires using existing technologies, it is often impossible to ensure that the wire axis and the moving direction of the roughness meter probe are kept in the same vertical plane, thus affecting the accuracy of the wire surface roughness measurement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a metal wire surface roughness measuring device to improve the accuracy of metal wire surface roughness measurement.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A surface roughness measuring device for metal wire includes a roughness meter and a wire feeding mechanism. The wire feeding mechanism includes a rotary slide, a displacement slide, and a wire feeding seat. The wire feeding seat is fixedly mounted on the displacement slide, and the displacement slide is fixedly mounted on the rotary slide. The wire feeding seat has multiple parallel wire feeding grooves. By adjusting the rotary slide and the displacement slide, the axis of the metal wire placed in the wire feeding groove is aligned with the moving direction of the measuring probe of the roughness meter in the same vertical plane.

[0007] In the metal wire surface roughness measuring device provided by this utility model, preferably, a positioning rod is detachably provided on the roughness meter, and the positioning rod can be installed at the same position as the sensor.

[0008] In the metal wire surface roughness measuring device provided by this utility model, more preferably, a positioning device for assisting in the alignment of the shaft is installed on the positioning rod.

[0009] In the metal wire surface roughness measuring device provided by this utility model, more preferably, the positioner is a dial indicator or a laser positioner.

[0010] In the metal wire surface roughness measuring device provided by this utility model, it is further preferred that the width and depth of the multiple wire feeding grooves are different.

[0011] In the metal wire surface roughness measuring device provided by this utility model, the wire feeding groove is further preferably "V" shaped.

[0012] In the metal wire surface roughness measuring device provided by this utility model, more preferably, a metal wire fixing member is also provided on the wire feeding seat, and the fixing member is located at the end of the wire feeding seat away from the roughness meter.

[0013] In the metal wire surface roughness measuring device provided by this utility model, the fixing element is even more preferably a pressure strip or tape.

[0014] In the metal wire surface roughness measuring device provided by this utility model, the pressure bar is preferably a metal block or a bar magnet.

[0015] The above technical solution incorporates a wire feeding mechanism, which includes a rotary slide, a displacement slide, and a wire feeding seat. A wire feeding groove is provided on the wire feeding seat, ensuring that the axis of the metal wire is always aligned with the displacement axis of the telescopic rod during surface roughness measurement, thus guaranteeing the accuracy of the measurement. The positioning rod and positioner allow for easy adjustment of the metal wire to ensure its axis is aligned with the travel axis of the telescopic rod. Multiple wire feeding grooves of different sizes allow for the measurement of surface roughness of metal wires with different diameters. The "V"-shaped wire feeding groove facilitates the placement and positioning of the metal wire and provides a self-centering effect. The fixing components effectively secure the metal wire to be measured, preventing movement during measurement and ensuring accuracy. Attached Figure Description

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Example 1

[0025] This embodiment provides a device for measuring the surface roughness of metal wires, such as... Figures 1 to 6 As shown, the device includes a roughness tester 1 (model TR3601) and a wire feeding mechanism. The wire feeding mechanism includes a rotary slide 2 (model RSP80-L), a displacement slide 3 (model LWX4060), and a wire feeding seat 4. The wire feeding seat 4 is fixedly mounted on the displacement slide 3 by screws, and the displacement slide 3 is fixedly mounted on the rotary slide 2 by screws. The wire feeding seat 4 has four parallel "V"-shaped wire feeding grooves 5 with different widths and depths, which can hold metal wires with diameters ranging from 0.2 mm to 5.0 mm. A positioning rod 6 is provided on the roughness tester 1. This positioning rod 6 is detachably mounted on the interface of the roughness tester 1 originally used to mount the sensor 10. A dial indicator (positioner 7) is mounted on the positioning rod 6. The positioning rod 6 shares a mounting position with the sensor 10 of the roughness tester 1, and is mounted on the telescopic rod 9 of the roughness tester 1. When the positioning rod 6 is needed, the sensor 10 is removed from the telescopic rod 9, and the positioning rod 6 is installed on the interface where the sensor 10 was originally installed. This is used to observe whether the axis of the wire to be tested is in the same vertical plane as the moving direction of the roughness tester 1 measuring probe 11.

[0026] The probe of the dial indicator (positioner 7) and the measuring probe 11 of the sensor 10 are in the same position. That is to say, the distance between the probe of the dial indicator and the roughness tester 1 is equal to the distance between the measuring probe 11 of the sensor 10 and the roughness tester 1.

[0027] In order to prevent the metal wire to be tested from shaking and make the measurement results more accurate, a metal wire fixing part 8 is also provided on the wire feeding seat 4. The fixing part 8 is located at the end of the wire feeding seat 4 away from the roughness tester 1, and the fixing part 8 is a metal block.

[0028] Example 2

[0029] In this embodiment, the positioner 7 dial indicator in embodiment 1 is replaced with a laser positioner, and the fixing part 8 is a bar magnet. Everything else is the same as in embodiment 1.

[0030] This utility model is used as follows: The roughness tester 1 and the wire feeding mechanism are fixed on the operating table, and the length direction of the wire feeding groove 5 is consistent with the travel direction of the telescopic rod 9 of the roughness tester 1. The sensor 10 of the roughness tester 1 is removed from the telescopic rod 9, and the positioning rod 6 is installed at the installation position of the sensor 10.

[0031] Turn the handle of the rotary slide 2 to adjust the angle of the wire feeding groove 5 on the wire feeding seat 4, so that the length direction of the wire feeding groove 5 is parallel to the travel direction of the telescopic rod 9 of the roughness tester 1. Place the metal wire to be tested in the wire feeding groove 5 and fix it with the fixing piece 8. The fixing piece 8 does not affect the measurement of the surface roughness of the metal wire. Turn the handle of the displacement slide 3 to precisely adjust the position of the metal wire so that the axis of the metal wire and the moving direction of the telescopic rod 9 of the roughness tester 1 are in the same vertical plane. Use the positioner 7—a dial indicator (or a laser positioner) installed on the positioning rod 6—to determine whether the axis of the metal wire and the travel axis of the telescopic rod 9 are in the same vertical plane. If a dial indicator is installed on the positioning rod 6, the judgment can be made by observing the runout of the dial indicator. When the runout is uniform, it indicates that the axis of the metal wire and the travel axis of the telescopic rod 9 are in the same vertical plane. If a laser positioning device is installed on the positioning rod 6, and the light spot emitted by the laser positioning device coincides with the highest point of the metal wire (i.e., the axis position), it indicates that the axis of the metal wire and the travel axis of the telescopic rod 9 are on the same vertical plane. After adjusting the position of the metal wire, the positioning rod 6 is removed, and the roughness meter 1 sensor 10 is reinstalled to measure the surface roughness of the metal wire.

[0032] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
