[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The present invention provides a wall thickness measuring device. Figure 1-4As shown, the wall thickness measuring device includes: a mounting frame 1, which is a U-shaped structure with one end open, which is formed by connecting a connecting rod, a connecting rod and a connecting rod in sequence; a mounting plate 2, which is fixedly mounted on a connecting rod; an electric telescopic rod 3, which is fixedly mounted on the mounting plate 2; a support frame 4, which includes a horizontal section and a vertical section, and the horizontal section is fixedly connected to the output rod of the electric telescopic rod; a spring 5, one end of the spring 5 is fixedly mounted on the vertical section, and the other end of the spring 5 is equipped with a resistance piece 6 extending to the three-section connecting rod; an adjusting rod 7, one end of the adjusting rod 7 is fixedly mounted on the resistance piece 6, and the other end of the adjusting rod passes through the spring 5 and the vertical section; a detection component, which is arranged on the support frame 4, and the detection component is used to assist in detecting the wall thickness.

[0022] In this embodiment, the mounting frame 1 and the mounting plate 2 constitute the basic structure of the entire device. The length of one connecting rod of the mounting frame is less than the length of three connecting rods, providing a stable support platform. The arrangement of the electric telescopic rod 3 enables the entire support frame 4 to adjust the height or position as needed, thereby enhancing its adaptability and flexibility. The combined design of the support frame 4, the spring 5 and the resistance member 6 enables the device to adaptively adjust the contact with the device wall during the detection process. The elastic action of the spring 5 ensures the stable contact between the resistance member 6 and the device wall, while reducing the measurement error caused by poor contact. The introduction of the adjustment rod 7 can detect the movement of the position of the resistance member 6, thereby further improving the measurement accuracy. This design is particularly suitable for devices with different wall thicknesses, so that the device can more accurately adapt to various measurement requirements.

[0023] In a further preferred embodiment of the utility model, the detection component includes a linear magnetic grating encoder 9 and a micro camera 10, and the linear magnetic grating encoder 9 and the micro camera 10 are both installed on a horizontal section. The linear magnetic grating encoder 9 is in contact with the adjusting rod 7, and the adjusting rod 7 is provided with a plurality of scale lines 8.

[0024] In this embodiment, the linear magnetic grating encoder 9 is a high-precision measuring device. Through direct contact with the adjusting rod 7, it can detect and record the displacement changes of the adjusting rod 7 in real time. The scale line 8 not only provides an intuitive reference for the operator, but also provides an accurate measurement benchmark for the linear magnetic grating encoder 9. This design enables the device to more accurately measure slight changes in the wall thickness of the equipment, thereby improving the measurement accuracy and reliability. The introduction of the micro camera 10 adds a visual detection function to the device.

[0025] In a further preferred embodiment of the utility model, a plurality of fill light beads 11 are installed at the bottom of the miniature camera 10, and two limit rods 12 are fixedly installed at the bottom of the miniature camera 10, and the two limit rods 12 clamp the adjustment rod 7 therein, and a positioning rod 13 is fixedly installed between the two limit rods 12, and the positioning rod 13 is located at the bottom of the miniature camera 10, and a transparent plastic section is provided on the positioning rod 13.

[0026] In this embodiment, the introduction of the fill light beads 11 effectively solves the problem that the micro camera 10 is difficult to obtain a clear image in a dim or uneven lighting environment. The fill light beads 11 can emit uniform and soft light, providing sufficient lighting for the micro camera 10, ensuring that the captured image of the device wall is clear and rich in details. The setting of the limit rod 12 makes the position of the adjustment rod 7 more stable.

[0027] In a further preferred embodiment of the utility model, a threaded rod 15 is threadedly installed on the first connecting rod, a clamping plate 17 located between the first connecting rod and the second connecting rod is rotatably installed on the threaded rod 15, and an adjustment block 16 located outside the mounting frame is fixedly installed on the threaded rod 15.

[0028] In this embodiment, the threaded rod 15 is installed on the mounting frame 1 by means of threads, so that its position can be fine-tuned as needed. The adjustment block 16 facilitates the operator to manually rotate the threaded rod 15, thereby adjusting the position of the clamping plate 17. The setting of the adjustment block 16 makes the adjustment process more intuitive and convenient, and improves the operating efficiency. By adjusting the position of the threaded rod 15, the clamping plate 17 can be tightly clamped on the equipment to ensure the stability of the device during the measurement process. This design not only improves the accuracy of the measurement, but also effectively prevents the device from slipping or shifting during the measurement process.

[0029] In a further preferred embodiment of the present invention, a plurality of balls 18 are embedded on a side of the clamping plate 17 away from the electric telescopic rod 3 , and a rubber protective sleeve 14 is provided on an outer fixed sleeve of the electric telescopic rod 3 .

[0030] In this embodiment, the introduction of the ball 18 changes the friction mode between the clamping plate 17 and the contact surface of the device from sliding friction to rolling friction, which greatly reduces the friction force. In this way, when adjusting the position of the device or performing wall thickness detection, the clamping plate 17 can slide more smoothly, reducing the operating resistance and improving the working efficiency. At the same time, the rolling friction also reduces the wear on the surface of the device and protects the integrity of the device. The rubber protective cover 14 has good elasticity and wear resistance, and can effectively protect the electric telescopic rod 3 from erosion and wear of the external environment, especially impurities such as oil, dust, etc. that may exist in the working environment. The rubber protective cover 14 can prevent these impurities from contacting the electric telescopic rod 3, thereby extending the service life of the electric telescopic rod 3.

[0031] In a further preferred embodiment of the utility model, a clamping rod 19 is fixedly installed on the side of the clamping plate 17 away from the multiple balls 18, and a limiting opening is provided on the connecting rod. The clamping rod 19 can pass through the limiting opening, and the clamping rod 19 contacts the inner wall of the limiting opening.

[0032] In this embodiment, the clamping rod 19 and the clamping plate 17 form a whole. When the clamping plate 17 is moved to a suitable position through the adjustment of the threaded rod 15, the clamping rod 19 will also move accordingly. The coordinated use of the clamping rod 19 and the limit mouth not only plays a role in positioning and fixing, but also enhances the overall stability of the device, effectively preventing the clamping plate 17 from rotating with the threaded rod 15 and affecting the stability of the clamping plate 17 translation.

[0033] In a further preferred embodiment of the utility model, the resistance member 6 is composed of a U-shaped plate 20 and a roller 21, the U-shaped plate 20 is fixedly mounted on the spring 5, the roller 21 is rotatably mounted on the U-shaped plate 20, and the roller 21 is made of plastic.

[0034] In this embodiment, the U-shaped plate 20 is fixedly mounted on the spring 5 to form a stable supporting structure. The roller 21 can rotate freely when needed, thereby reducing the friction between the roller and the wall of the equipment. The roller 21 is made of plastic material, which not only has a light weight but also has a certain wear resistance. When the plastic roller 21 contacts the wall of the equipment, it can effectively reduce friction and wear and protect the integrity of the wall of the equipment.

[0035] In summary, compared with the related art, the present device can adjust the position of the detection component by setting the electric telescopic rod 3, so that the wall thickness of the device at different depths can be detected. The moving distance of the adjustment rod 7 can be detected by setting the detection component, so that whether the inner wall of the device is flat can be understood while detecting the wall thickness. The threaded rod 15 and the clamping plate 17 can be set to stabilize the present device on the device without affecting the adjustment of the position of the device.
