[0004] Based on the aforementioned existing technology, the existing cover part wall thickness detection devices still have the following problems: the existing covers have different shapes, but the traditional fixed clamping mechanism cannot adjust the cover angle, resulting in a detection blind spot. Therefore, this utility model provides a cover part wall thickness detection device. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a cover part wall thickness detection device, which solves the following problems that existing cover part wall thickness detection devices still have: the shapes of existing covers are not uniform, but the traditional fixed clamping mechanism cannot adjust the cover angle, resulting in a detection blind zone.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a cover part wall thickness detection device, comprising a base, a linear motion slide rail fixedly mounted on the top of the base, and an ultrasonic thickness gauge fixedly mounted on the movable seat of the linear motion slide rail; an adjustment mechanism is provided above the base for rotating the cover to detect the wall thickness at different positions; the adjustment mechanism includes:
[0007] The rotating unit is located above the base and includes a rotating seat. A rotating shaft is rotatably mounted inside the rotating seat, and a large gear is fixedly mounted on the surface of the rotating shaft. A three-jaw chuck is rotatably mounted on the top of the rotating shaft. The large gear and the rotating shaft drive the three-jaw chuck to rotate, thereby rotating the cover plate and enabling the detection of the wall thickness at different positions of the cover plate.
[0008] The movable unit is located below the base and is used to adjust the detection distance between the cover plate and the ultrasonic thickness gauge.
[0009] Preferably, a mounting box is fixedly installed on one side of the rotating base, and a small gear is rotatably installed inside the mounting box. A handwheel is rotatably installed on the top of the mounting box, and the bottom end of the handwheel extends through the mounting box to the top of the small gear and is fixedly connected to the small gear to realize the rotation of the small gear.
[0010] Preferably, the small gear is installed by meshing with the large gear through the through slot of the rotating seat, so that the small gear drives the large gear to rotate.
[0011] Preferably, the moving unit includes a mounting base fixedly installed above the base, and the mounting base has a convex groove inside, and a convex block is slidably installed inside the convex groove. A moving plate is fixedly installed on the top of the convex block, and the moving plate slides linearly above the mounting base. A rotating seat is fixedly installed above the moving plate.
[0012] Preferably, the convex block has a plurality of threaded holes inside, and threaded pins are inserted into the threads of the threaded holes.
[0013] Preferably, the rotation of the threaded pin causes the bottom end to press against the bottom of the convex groove, thereby fixing the position of the convex block and adjusting the detection distance between the cover plate and the ultrasonic thickness gauge.
[0014] This invention provides a device for detecting the wall thickness of a cover part. Compared with the prior art, it has the following advantages:
[0015] 1. The cover part wall thickness detection device is equipped with a rotating unit.

[0016] 2. The cover part wall thickness detection device is equipped with a moving unit. The user pushes and pulls the convex block, so that the convex block is limited and slides inside the convex groove. The convex block drives the moving plate to move. The moving plate drives the cover to move through the rotating unit and the three-jaw chuck, thereby adjusting the distance between the ultrasonic thickness gauge and the cover. This prevents the cover from protruding too much and the distance from the ultrasonic thickness gauge from being inconsistent, which would result in poor detection results.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-4 This utility model provides a technical solution:
[0024] A cover plate wall thickness detection device includes a base 1, a linear motion slide rail 3 fixedly mounted on the top of the base 1, and an ultrasonic thickness gauge 4 fixedly mounted on the movable seat of the linear motion slide rail 3. An adjustment mechanism 2 is provided above the base 1 for rotating the cover plate to detect the wall thickness at different positions. The adjustment mechanism 2 includes:
[0025] The rotating unit 21 is located above the base 1 and includes a rotating seat 211. A rotating shaft 212 is rotatably mounted inside the rotating seat 211. A large gear 213 is fixedly mounted on the surface of the rotating shaft 212. A three-jaw chuck 5 is rotatably mounted on the top of the rotating shaft 212. The large gear 213 and the rotating shaft 212 drive the three-jaw chuck 5 to rotate, thereby rotating the cover plate and enabling the detection of the wall thickness at different positions of the cover plate.
[0026] The movable unit 22 is located below the base 1 and is used to adjust the detection distance between the cover plate and the ultrasonic thickness gauge 4.
[0027] The ultrasonic thickness gauge 4, model ULTRAMAC, drives the small gear 215 and the large gear 213 through the handwheel 216 to rotate the cover plate, thereby realizing the wall thickness detection of the cover at different angles. This completely eliminates the blind spot caused by the inability to adjust the angle in the traditional fixed clamping mechanism, and improves the detection coverage and accuracy.
[0028] In this embodiment, a mounting box 214 is fixedly installed on one side of the rotating base 211, and a small gear 215 is rotatably installed inside the mounting box 214. A handwheel 216 is rotatably installed on the top of the mounting box 214, and the bottom end of the handwheel 216 extends through the mounting box 214 to the top of the small gear 215 and is fixedly connected to the small gear 215 to realize the rotation of the small gear 215.
[0029] The handwheel 216 is directly and fixedly connected to the pinion 215, allowing operators to easily control the rotation of the cover plate by rotating the handwheel, simplifying the operation process and improving testing efficiency.
[0030] In this embodiment, the small gear 215 is meshed with the large gear 213 through the through slot of the rotating seat 211, so that the small gear 215 drives the large gear 213 to rotate.
[0031] The pinion 215 meshes precisely with the large gear 213 through a through slot, ensuring stable and slip-free transmission torque, avoiding detection deviations caused by transmission errors, and enhancing the reliability of rotation control and measurement repeatability.
[0032] In this embodiment, the moving unit 22 includes a mounting base 221 fixedly installed above the base 1, and the mounting base 221 has a convex groove 222 inside, and a convex block 223 is slidably installed inside the convex groove 222. A moving plate 224 is fixedly installed on the top of the convex block 223, and the moving plate 224 slides linearly above the mounting base 221. A rotating seat 211 is fixedly installed above the moving plate 224.
[0033] The convex block 223 slides within the convex groove 222, which drives the moving plate 224 and the rotating unit to move as a whole, flexibly adjusting the detection distance between the cover and the ultrasonic thickness gauge 4, adapting to cover parts of different sizes or shapes, and improving the versatility and applicability of the device.
[0034] In this embodiment, the convex block 223 has several threaded holes 225 inside, and threaded pins 226 are inserted into the threads inside the threaded holes 225.
[0035] By rotating the threaded pin 226 to press the bottom of the convex groove 222, the position of the convex block 223 is quickly locked, ensuring that the adjusted detection distance is fixed and reliable, avoiding displacement caused by vibration or external force during the detection process, and ensuring the stability of the measurement results.
[0036] In this embodiment, the rotation of the threaded pin 226 causes its bottom end to press against the bottom of the convex groove 222, thereby fixing the position of the convex block 223 and adjusting the detection distance between the cover plate and the ultrasonic thickness gauge 4.
[0037] The threaded design of the 226 threaded pin provides progressive locking force, enabling stepless adjustment and ensuring a secure hold through mechanical self-locking, simplifying the adjustment process and improving operational safety.
[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0039] During operation, the user first pushes and pulls the convex block 223 so that the convex block 223 is limited and slides inside the convex groove 222. The convex block 223 drives the moving plate 224 to move. The moving plate 224 drives the cover to move through the rotating unit 21 and the three-jaw chuck 5, adjusting the distance between the ultrasonic thickness gauge 4 and the cover.
[0040] Then, the user turns the handwheel 216, which drives the large gear 213 to rotate. The small gear 215 drives the large gear 213 to rotate, and the large gear 213 drives the rotating shaft 212 to rotate. The rotating shaft 212 drives the three-jaw chuck 5 to rotate, which in turn drives the cover plate to rotate. At the same time, the ultrasonic thickness gauge 4 is activated and moves up and down through the linear motion slide rail 3 to detect the wall thickness at different positions of the cover.
