[0002] Painted parts are components that are coated with paint on a metal or plastic surface and then baked at high temperatures. During production, a coating thickness gauge is needed to measure the thickness of the paint layer. The coating thickness gauge uses electromagnetic induction or magnetic measurement principles and is suitable for measuring the coating thickness on metal substrates. It has high precision and is convenient.
[0003] The coating thickness gauge includes the main body of the gauge, connecting lines, and a sensing head. The main body is equipped with a data processing system, a display component, and control buttons. The connecting lines connect the main body and the sensing head. The sensing head is used to sense and measure the thickness of the paint layer. The thickness information sensed by the sensing head is transmitted to the main body through the connecting lines, where it is processed by the data processing system and then displayed on the display component.
[0004] Regarding the above-mentioned technical conditions, there is also a defect that when using the coating thickness gauge, one hand needs to hold the main body and the other hand needs to hold the sensing head to make the sensing head contact the object to be measured. However, the contact between the sensing head and the object to be measured by holding it by hand is not stable enough, resulting in inaccurate measurement results.
[0005] Based on this, this utility model designs a thickness gauge to improve testing accuracy in order to solve the above problems. Utility Model Content

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0022] A thickness gauge for improving testing accuracy includes a main body 1, a connecting cable 2, and an inductive measuring head 4. One end of the connecting cable 2 is connected to the main body 1, and the other end is connected to the inductive measuring head 4. The inductive measuring head 4 is equipped with a positioning structure, which makes the inductive measuring head 4 more stable when in contact with the object to be measured, thus making the measurement results more accurate.
[0023] The positioning structure includes a base 5, a support rod 6, a positioning plate 13, and a threaded rod 7. The support rod 6 is fixedly mounted on the base 5, and a mounting bracket 10 is fixedly connected to the support rod 6. A movable plate 11 is slidably connected to the mounting bracket 10, and the positioning plate 13 is fixedly connected to the movable plate 11. A spring 14 is connected to the movable plate 11, and one end of the spring 14 is fixedly connected to the mounting bracket 10.
[0024] The positioning plate 13 has a positioning hole 3 and a threaded hole, which communicates with the positioning hole 3. The inductive measuring head 4 is inserted into the positioning hole 3 with the direction in which the inductive head is facing. The threaded rod 7 is threaded into the threaded hole, and one end of the threaded rod 7 passes through the threaded hole and abuts against the inductive measuring head 4. The inductive measuring head 4 is clamped between the positioning hole 3 and the threaded rod 7.
[0025] An auxiliary rod 9 is fixedly connected to the movable plate 11. When measuring the thickness of an item, place the item on the base 5, hold the auxiliary rod 9 and press down. The movable plate 11 slides down on the mounting bracket 10, and the spring 14 extends. Under the action of the movable block and the spring 14, the positioning plate 13 moves down steadily with the sensing measuring head 4. The sensing measuring head 4 makes stable contact with the item, so that the measurement result obtained by the sensing measuring head 4 is more accurate.
[0026] A limiting plate 8 is fixedly connected to the movable plate 11. A limiting hole is opened on the limiting plate 8 and the limiting hole is sleeved on the support rod 6. The end of the spring 14 away from the mounting frame 10 is fixedly connected to the limiting plate 8. The spring 14 is between the mounting frame 10 and the limiting plate 8. The limiting plate 8, the movable plate 11 and the spring 14 cooperate with each other to make the up and down movement of the movable plate 11 more stable.
[0027] A limiting groove 12 is provided on the support rod 6, and a limiting block is fixedly connected in the limiting hole. The limiting block is inserted into the limiting groove 12. The limiting groove 12 and the limiting block are designed to further increase the movement stability of the moving plate 11. A buffer layer is fixedly connected to the inner wall of the positioning hole 3, and a buffer plate is fixedly provided on the end of the threaded rod 7 near the positioning hole 3. When the sensing measuring head 4 is clamped between the positioning hole 3 and the threaded rod 7, the buffer layer and the buffer plate protect the sensing measuring head 4.
[0028] The implementation principle of this embodiment is as follows: In use, the inductive measuring head 4 is inserted into the positioning hole 3 with the inductive head facing downwards, and then the threaded rod 7 is tightened so that the inductive measuring head 4 is clamped between the positioning hole 3 and the threaded rod 7. The object to be measured is placed on the base 5, the auxiliary rod 9 is held and pressed down, the moving plate 11 moves downwards on the mounting bracket 10, the spring 14 extends, and the limiting block moves downwards in the limiting groove 12. Under the action of the moving plate 11, the spring 14 and the limiting block, the positioning plate 13 moves the inductive measuring head 4 downwards stably, and the inductive measuring head 4 makes stable contact with the object. In this way, the measurement result obtained by the inductive measuring head 4 is more accurate, thereby improving the accuracy of the thickness gauge measurement result.
