Description

Technical Field

[0001] The utility model belongs to the technical field of detection of brass-plated steel wires, and particularly relates to a fixture for detecting the coating content of brass-plated steel wires. Background Technique

[0002] Brass electroplating on steel wires is a surface coating process in which a brass layer is plated on the surface of steel wires by electroplating. The coating composition is about 65% - 70% copper and about 35% - 30% zinc. The purpose of brass electroplating on steel wires is to increase the bonding force between tire steel wires and rubber. The coating itself is also suitable for plastic processing, can deform simultaneously with the steel wires, and is beneficial for drawing. In order to ensure the quality of the brass layer electroplated on the steel wire surface, after the brass layer is electroplated, it is necessary to detect the coating content. For the detection of the coating content, an X-ray fluorescence spectrometer is usually used to detect the coating content of brass-plated steel wires. During the detection, the steel wire samples need to be closely and neatly arranged and fixed. During the detection process, the samples cannot be loose and there should be no gaps between the samples. If the steel wires move during the detection, it will directly affect the detection data and lead to inaccurate detection results. For this reason, we have proposed a fixture for detecting the coating content of brass-plated steel wires. Summary of the Invention

[0003] The utility model provides a fixture for detecting the coating content of brass-plated steel wires, which solves the problems raised in the above background technique.

[0004] To achieve the above object, the utility model is realized through the following technical solutions: A fixture for detecting the coating content of brass-plated steel wires, including a clamping base and a clamping top seat. The clamping top seat is placed on the clamping base. The clamping base is hollow, and two opposite connecting parts are fixedly installed on the top of the clamping base. Threads are provided on the outer sides of the connecting parts, and the clamping top seat is threadedly connected to the outer sides of the connecting parts. A first spring is fixedly connected to the middle of the bottom of the clamping top seat, and the bottom end of the first spring is fixedly connected to a limiting plate that can contact the top of the steel wire sample.

[0005] Further, the steel wire sample is placed on the top of the clamping base between the two connecting parts, and the bottom of the limiting plate contacts the top of the steel wire sample.

[0006] Further, the surfaces of the clamping base and the limiting plate that contact the steel wire sample are made of rubber material.

[0007] Further, a circular depression is formed inwardly at the connection between the connecting part and the top of the clamping base, and a limiting block that can contact the top of the circular depression is connected to the clamping top seat.

[0008] Further, the limiting block is movably connected to the bottom end inside the clamping top seat, and the top of the inner side end of the limiting block is arc-shaped, and the arc-shaped surface of the limiting block abuts against the top of the circular depression.

[0009] Further, a cylindrical transmission column is fixedly connected to the top of one end of the limiting block inside the clamping top seat, and a second spring is fixedly connected to one end of the limiting block inside the clamping top seat, and the second spring is fixed to the clamping top seat.

[0010] Further, a rotation ring plate with an L-shaped cross-section is movably sleeved on the bottom end outside the clamping top seat. A driving chute corresponding to the transmission column is formed on the rotation ring plate. The driving chute is an arc-shaped structure that gradually approaches the center of the rotation ring plate, and the transmission column is movably connected to the driving chute. Beneficial effects

[0011] 1. For the fixture for detecting the coating content of brass-plated steel wires, since the center of the clamping base is empty, the light source of the instrument can be projected from the bottom onto the surface of the placed sample. The clamping can be completed by screwing the clamping top seat and the connecting part. With the action of the first spring and the limiting plate, the steel wire samples can be pressed tightly and all the steel wire samples can be arranged on the same plane, thus ensuring that the steel wire samples can be stably detected.

[0012] 2. For the fixture for detecting the coating content of brass-plated steel wires, under the action of the elastic force of the second spring, the arc-shaped surface of the limiting block can abut against the circular depression between the connecting part and the clamping base, and then the clamping top seat can be locked to avoid the situation of thread slipping of the clamping top seat, making its fixation more firm.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 5 , a fixture for detecting the coating content of brass-plated steel wire, including a clamping base 1 and a clamping top seat 2. The clamping top seat 2 is placed on the clamping base 1. The clamping base 1 is hollow, so that the light source of the instrument can enter from the bottom and shine on the surface of the placed steel wire sample 3, so that the steel wire sample 3 can be smoothly detected. And two opposite connecting parts 6 are fixedly installed on the top of the clamping base 1. Threads are provided on the outer side of the connecting part 6, and a clamping top seat 2 is threadedly connected to the outer side of the connecting part 6. Through the threaded connection between the clamping top seat 2 and the connecting part 6, the clamping top seat 2 can be connected to the clamping base 1 and fixedly installed. The middle of the bottom of the clamping top seat 2 is fixedly connected with a first spring 4, and the bottom end of the first spring 4 is fixedly connected with a limiting flat plate 5 that can contact the top of the steel wire sample 3. When the clamping top seat 2 is continuously screwed and installed, the first spring 4 is gradually compressed, so that the limiting flat plate 5 can apply pressure to the steel wire sample 3, so that the steel wire sample 3 can be gradually clamped, giving a certain buffer, so as to better protect the steel wire sample 3.

[0023] Please refer to Figures 1 to 5 , the steel wire sample 3 is placed on the top of the clamping base 1 between the two connecting parts 6, and the bottom of the limiting flat plate 5 is in contact with the top of the steel wire sample 3, so that the clamping base 1 and the limiting flat plate 5 can complete the clamping of the steel wire sample 3, so that it can be stably detected.

[0024] Please refer to Figures 1 to 5 , the surfaces of the clamping base 1 and the limiting flat plate 5 in contact with the steel wire sample 3 are made of rubber material, so as to increase the friction with the steel wire sample 3, so that the fixation of the steel wire sample 3 is more stable and can play a certain protective role on the steel wire sample 3.

[0025] Please refer to Figures 1 to 7 , the entire fixture is made of acetal resin.

[0026] Please refer to Figures 1 to 7 , a circular depression is formed inwardly at the connection between the connecting portion 6 and the top of the clamping base 1, and a limiting block 9 that can contact the top of the circular depression is connected to the clamping top seat 2. The position of the clamping top seat 2 can be locked by the limiting block 9, making its connection more secure.

[0027] Please refer to Figures 1 to 7 , the limiting block 9 is movably connected to the bottom end inside the clamping top seat 2. The limiting block 9 can move along a fixed trajectory on the clamping top seat 2, and the top of the inner end of the limiting block 9 is arc-shaped. The arc-shaped surface of the limiting block 9 abuts against the top of the circular depression, enabling the limiting block 9 to adapt to clamping in various situations, such as when the friction between the thread between the connecting portion 6 and the clamping top seat 2 increases.

[0028] Please refer to Figures 1 to 7 , a cylindrical transmission column 11 is fixedly connected to the top of the end of the limiting block 9 inside the clamping top seat 2. Driven by the transmission column 11, the limiting block 9 can move. And a second spring 10 is fixedly connected to the end of the limiting block 9 inside the clamping top seat 2. The second spring 10 is fixed to the clamping top seat 2. Under the action of the elastic force of the second spring 10, the limiting block 9 can automatically extend and abut against the circular depression, thereby limiting the clamping top seat 2.

[0029] Please refer to Figures 1 to 7 , a rotation ring plate 7 with an L-shaped cross-section is movably sleeved on the bottom end outside the clamping top seat 2. A driving chute 8 corresponding to the transmission column 11 is provided on the rotation ring plate 7. The driving chute 8 is an arc-shaped structure that gradually approaches the center of the rotation ring plate 7. And the transmission column 11 is movably connected in the driving chute 8. When the rotation ring plate 7 rotates, the transmission column 11 moves relatively in the driving chute 8, enabling the rotation of the rotation ring plate 7 to drive the limiting block 9 to move into the clamping top seat 2 to ensure that the clamping top seat 2 can be smoothly threadedly connected to the connecting portion 6.

[0030] In summary, when using the fixture for detecting the coating content of brass-plated steel wires, place the steel wire sample 3 on the clamping base 1 between the connecting parts 6, then align the limiting flat plate 5 between the connecting parts 6, and then screw the rotating ring plate 7, so that the driving column 11 can move relative to the driving chute 8, and then the driving column 11 can drive the limiting block 9 to move into the clamping top seat 2. Then screw the clamping top seat 2 again, so that the clamping top seat 2 can be installed on the connecting part 6, and its limiting flat plate 5 can contact the steel wire sample 3, and the steel wire sample 3 can be laid flat on the clamping base 1. As the clamping top seat 2 is gradually screwed, the first spring 4 is gradually compressed, so that the limiting flat plate 5 can press the steel wire sample 3. After the installation of the clamping top seat 2 is completed, loosen the rotating ring plate 7. Under the action of the elastic force of the second spring 10, it can push the limiting block 9 to move, and then the limiting block 9 can abut against the top of the circular depression, so as to lock the clamping top seat 2 and make the fixation of the clamping top seat 2 more stable.
