Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a copper-aluminum composite plate thickness detection device. Background Art

[0002] Copper-aluminum composite material is a layered composite conductor material that combines the advantages of copper and aluminum or aluminum alloy. It has the advantages of conductivity, lightweight, low cost and corrosion resistance. It plays an important role in high-end equipment fields such as new energy, rail transportation, aerospace, etc. Copper-aluminum composite plates are made of copper-aluminum composite materials. However, in the production process of copper-aluminum composite plates, in order to ensure production quality, the thickness of the copper-aluminum composite plates needs to be tested. Nowadays, there are many instruments for testing copper-aluminum composite plates, including ultrasonic thickness gauges.

[0003] Nowadays, when ultrasonic thickness gauges are used to detect the thickness of copper-aluminum composite plates, coupling agent needs to be applied to the surface of the plates to improve the detection effect. However, the operation of applying coupling agent is generally manual, so it is easy to apply too much or too little coupling agent during the application process. When too much coupling agent is used, when the probe leaves the workpiece, the instrument indication may show the thickness value of the coupling agent layer rather than the actual thickness of the object being measured. If too little coupling agent is used or the application is uneven, the air gap between the probe and the object being measured cannot be completely eliminated, which will lead to the obstruction of ultrasonic wave propagation, reduce the sound intensity transmittance, and thus affect the accuracy of the measurement results.

[0024] like Figures 1-9 As shown, the present invention provides a copper-aluminum composite plate thickness detection device, which includes a detector 1, a probe 2, a protective cover 3, a rotating disk 6, a plurality of material blocks 7, a rotating mechanism, and a storage cylinder 4.

[0025] like Figures 1-9 As shown, the probe 2 is arranged on the detector 1, the protective cover 3 is arranged on the probe 2, the rotating disk 6 is arranged in the protective cover 3, and multiple material blocks 7 are arranged on the rotating disk 6. The material selection of the material blocks 7 can be selected according to the material to be detected, thereby improving the applicability of the detection device. The rotating mechanism is arranged on the protective cover 3, and the positions of the multiple material blocks 7 are adjusted by the rotating mechanism. The storage cylinder 4 is installed on the protective cover 3, and the bottom of the storage cylinder 4 is in contact with the top of the rotating disk 6.

[0026] like Figure 3 As shown, a through hole 1 is provided on the top of the protective cover 3, and a buffer member 5 is provided above the through hole. The buffer member 5 is composed of a connecting ring, a connecting rod and a connecting spring. The connecting ring is provided above the through hole 1, and the connecting rod is installed at the bottom of the connecting ring. The connecting rod passes through the protective cover 3 and is slidably connected to the protective cover 3. The connecting spring is sleeved on the connecting rod. During actual use, the outer diameter of the outer wall of the bottom end of the probe 2 is the same as the inner diameter of the inner wall of the connecting ring. The buffer member 5 ensures the position of the probe 2 while facilitating pressing the probe 2, so that the probe 2 can better contact with the material block 7, thereby improving the detection effect of the probe 2.

[0027] like Figure 9 As shown, the top and bottom of the storage tube 4 are both set as the second opening. The top of the storage tube 4 is provided with a plug 18, which is threadedly connected to the storage tube 4. The coupling agent can be pre-stored through the storage tube 4.

[0028] like Figure 3 and Figure 8As shown, the rotating mechanism includes a rotating assembly and a limiting assembly. The rotating assembly includes a rotating column 8 rotatably mounted on the protective cover 3. The bottom end of the rotating column 8 is connected to the rotating disk 6. The top of the rotating column 8 is set in a T shape. The limiting assembly includes a pulling block 11 slidably mounted on the rotating column 8. A connecting member 13 is slidably mounted on the rotating column 8. The connecting member 13 is connected to the pulling block 11. A rotating button 9 is installed on the connecting member 13. Two grooves 2 are provided on the outer wall of the rotating column 8. The connecting member 13 is composed of two arc plates. The two arc plates are respectively arranged on the two In the second groove, the two arc-shaped plates are respectively slidably connected to the two second grooves, a limit spring is provided on the connecting piece 13, a plug rod 12 is installed on the pulling block 11, a positioning hole 10 is provided on the protective cover 3, the plug rod 12 is adapted to the positioning hole 10, and the positioning holes 10 are arranged in a ring around the rotating column 8. The number of positioning holes 10 is twice the number of material blocks 7. By inserting the plug rod 12 into the positioning hole 10, the rotation of the rotating column 8 is limited, thereby limiting the rotating disk 6, thereby ensuring the stability of the position of the material block 7.

[0029] like Figure 4-Figure 7 As shown, a placement slot 14 is provided on the rotating disk 6, and the placement slot 14 is set in a countersunk shape. After the material block 7 fills the placement slot 14, the thickness of one end of the placement slot 14 is the filling thickness of the coupling agent. In this way, the setting thickness of the coupling agent can be accurately controlled to improve the detection effect of the probe 2. A positioning slot 17 is provided on the inner wall of the placement slot 14, and a mounting ring 15 is provided on the material block 7. A groove 1 is provided on the mounting ring 15, and a positioning block 16 is slidably installed in the groove 1. The outer wall of one side of the positioning block 16 is set in an inclined surface. In the process of installing the material block 7, the positioning block 16 will shrink into the groove 1 when it contacts the inner wall of the placement slot 14. Therefore, the material block 7 can be quickly installed by pressing, thereby improving the installation efficiency of the material block 7. A return spring is installed in the groove 1, and the return spring is connected to the positioning block 16, and the positioning block 16 is adapted to the positioning slot 17.

[0030] like Figure 5 and Figure 6 As shown, a socket is provided at the bottom of the rotating disk 6, and the socket is connected to the positioning groove 17. In this embodiment, a round needle adapted to the socket is also required. When the material block 7 is disassembled, it is only necessary to insert the round needle into the socket. The positioning block 16 can be pushed into the groove 1 by the round needle. As a result, under the action of gravity, the mounting ring 15 drives the material block 7 to separate from the rotating disk 6, thereby improving the replacement efficiency of the material block 7.

[0031] In this embodiment, before use, the same material as the copper-aluminum composite plate is selected as the material block 7. The material block 7 is then placed into the placement groove 14 by pressing. The material block 7 is limited by the positioning block 16 and the positioning groove 17. Then, an appropriate amount of coupling agent is injected into the storage tube 4. The coupling agent falls above the material block 7 under the influence of gravity. The probe 2 is then installed on the protective cover 3.

[0032] During use, the knob 9 can be pulled to drive the insertion rod 12 out of the positioning hole 10, and the knob 9 can be turned to drive the rotating disk 6 to rotate, and then the material block 7 can be driven to rotate, so that the material block 7 with the coupling agent on the top is moved to the bottom of the probe 2. Then, by pressing the probe 2, the probe 2 can be better contacted with the material block 7, and the thickness of the copper-aluminum composite plate can be detected by the detector 1. The thickness of the copper-aluminum composite plate is obtained by subtracting the thickness of the material block 7 from the test result.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
