Description

Technical Field

[0001] This utility model belongs to the technical field of thickness detection devices, and in particular relates to a thickness detection device with linkage multi-point detection. Background Technology

[0002] A thickness measurement device is an automated device used to measure the thickness of materials or objects. It is widely used in manufacturing, materials processing, new energy, semiconductor and other fields.

[0003] During thickness detection, probes can only detect specific points or areas and cannot cover the entire surface of the object being measured. This is especially true when there is uneven thickness distribution, which may lead to incomplete measurement data, low efficiency, and even affect product quality control. Therefore, it is necessary to provide a measurement probe with adjustable spacing to improve the accuracy of thickness detection. Utility Model Content

[0004] The purpose of this invention is to provide a thickness detection device with linkage multi-point detection. Through threaded transmission, inclined groove limiting and synchronous movement, the left and right positions of the thickness probe can be precisely controlled to adapt to the thickness measurement needs of different detection points, improve the accuracy of measurement data, and avoid problems that may lead to incomplete measurement data, low efficiency, or even affect product quality control.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A thickness detection device with linkage multi-point detection includes a measuring platform, a controller, a connecting line, an ultrasonic thickness gauge and a thickness probe. The controller is fixed in the middle of the upper surface of the measuring platform, the connecting line is fixedly connected to one side of the controller, the ultrasonic thickness gauge is connected to the end of the connecting line, and the thickness probe is fixed at the lower end of the ultrasonic thickness gauge.

[0007] The interval assembly includes a fixed frame, a fixed bracket, a threaded rod, a lifting plate, and an inclined groove. The fixed frame is located above the measuring table, the fixed bracket is fixed to the middle of the upper surface of the fixed frame, the threaded rod is threaded through the inside of the fixed bracket, the lifting plate is slidably disposed inside the fixed frame, and the inclined groove is formed on the outer surface of the lifting plate.

[0008] Preferably, the upper surface of the measuring table is fixed with a slide rail, and the slide rail is connected to an external power source, and the workpiece to be measured is slidably placed on the surface of the slide rail.

[0009] By adopting the above technical solution, the measuring table serves as a support platform for the workpiece being measured, providing a stable foundation for placement. The connecting cable physically connects the controller and the ultrasonic thickness gauge, transmitting electrical signals and data. The ultrasonic thickness gauge emits and receives ultrasonic signals, and determines the thickness of the workpiece by calculating the time difference of sound wave propagation in the material. The thickness probe, as the ultrasonic transmitter and receiver, directly contacts or approaches the workpiece being measured. The fixed frame serves as the outer shell of the spacer assembly, supporting components such as the lifting plate and threaded rod. The fixed frame is used to install the threaded rod and support its rotation. The threaded rod drives the fixed block to move up and down through rotational motion, thereby adjusting the position of the lifting plate and the ultrasonic thickness gauge. The lifting plate connects the fixed block and the ultrasonic thickness gauge, converting the rotational motion of the threaded rod into vertical linear motion. Through the angle and shape of the inclined groove, the vertical motion of the lifting plate is converted into the horizontal motion of the limiting rod.

[0010] Preferably, the rear side wall of the fixed frame is provided with a square groove, and the rear side wall of the lifting plate is fixed with a fixing block, which slides through the square groove.

[0011] By adopting the above technical solution, the controller, as the core control unit of the system, is responsible for coordinating the actions of components such as the ultrasonic thickness gauge and the threaded rod.

[0012] Preferably, the upper surface of the fixing block is provided with a threaded hole, and the threaded rod is threaded through the threaded hole. A limit rod is fixed on the rear side of the lifting plate, and the limit rod slides through the inclined groove.

[0013] By adopting the above technical solution, the fixed block restricts its movement to only up and down through the square groove, thus avoiding horizontal displacement.

[0014] Preferably, three limiting posts are fixed inside the fixed frame, and the ultrasonic thickness gauge slides through the limiting posts.

[0015] By adopting the above technical solution, the limiting rod slides in the inclined groove, pushing the ultrasonic thickness gauge to move horizontally along the limiting column. The limiting column provides horizontal guidance and limitation for the ultrasonic thickness gauge.

[0016] Preferably, it also includes a lifting assembly, which includes a motor, a first connecting rod, a second connecting rod, a movable plate, and a fixed column. The motor is fixed inside the lower end of the controller. One end of the first connecting rod is fixed to the output end of the motor. One end of the second connecting rod is rotatably mounted on the end of the first connecting rod. The movable plate contacts the end of the second connecting rod, and the fixed column is fixed on one side of the outer surface of the movable plate, and the fixed column rotatably passes through the end of the second connecting rod.

[0017] By adopting the above technical solution, the motor serves as the power source, driving the first connecting rod through rotational motion, thereby driving the movement of the entire lifting assembly. The first connecting rod transmits the rotational motion of the motor to the second connecting rod, acting as a bridge for power transmission. One end of the second connecting rod is connected to the first connecting rod, and the other end contacts the movable plate through a fixed column, forming a rotation fulcrum.

[0018] Preferably, the controller has two limiting rails fixed to its front side, and the movable plate is slidably placed inside the limiting rails. A connecting plate is fixed to one side of the movable plate, and a fixing frame is fixed inside the connecting plate.

[0019] By adopting the above technical solution, the limiting rail provides vertical guidance and limitation for the movable plate, ensuring that its lifting process proceeds along a fixed path, and the connecting plate, as the connecting component between the movable plate and the fixed frame, transmits the lifting motion.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model, through a measuring platform, controller, slide rail, connecting line, ultrasonic thickness gauge, thickness probe, and spacing assembly, allows for precise control of the thickness probe's left and right positions during testing. During testing, the operator rotates a threaded rod clockwise, causing a fixed block to move downwards. This movement synchronously moves a lifting plate downwards, and under the constraint of the inclined groove, a limiting rod moves to both sides within the groove, causing the ultrasonic thickness gauge to move on both sides of the outer surface of the limiting post. Simultaneously, the thickness probe moves to both sides. The operator then rotates the threaded rod counterclockwise, causing the fixed block to move upwards. Under the constraint of the inclined groove, the limiting rod moves towards the center within the groove, causing the ultrasonic thickness gauge to move towards the center of the outer surface of the limiting post. Through threaded transmission, inclined groove limiting, and synchronous movement, the left and right positions of the thickness probe can be precisely controlled, adapting to the thickness measurement needs of different testing points and improving the accuracy of the measurement data.

[0022] 2. This utility model, through its lifting assembly, enables the controller to start the motor during testing. The motor drives the first connecting rod to rotate, and the rotation of the first connecting rod synchronously rotates one end of the second connecting rod, causing the other end of the second connecting rod to rotate on the fixed column. This causes the movable plate to reciprocate up and down on the limit rail. The lifting and lowering of the movable plate synchronously drives the lifting and lowering of the connecting plate and the interval assembly. The motor drives the movable plate to move up and down, causing the connecting plate and the interval assembly to lift and lower as a whole. The lifting and lowering range of the movable plate can cover the test objects of various thicknesses, enhancing the versatility of the equipment.

[0023] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The operator rotates the threaded rod 23 counterclockwise, causing the fixed block 25 to move upwards.

[0034] Example 2:

[0035] Please see Figure 1-5As shown, a multi-point thickness detection device with linkage includes a lifting assembly. The lifting assembly comprises a motor 31, a first connecting rod 32, a second connecting rod 33, a movable plate 34, and a fixed column 35. The motor 31 is fixed inside the lower end of the controller 12. One end of the first connecting rod 32 is fixed to the output end of the motor 31. One end of the second connecting rod 33 is rotatably mounted on the end of the first connecting rod 32. The movable plate 34 contacts the end of the second connecting rod 33, and the fixed column 35 is fixed to one side of the outer surface of the movable plate 34, and the fixed column 35 rotatably passes through the end of the second connecting rod 33.

The motor 31 drives the first connecting rod 32 to rotate. The rotation of the first connecting rod 32 synchronously rotates one end of the second connecting rod 33, causing the other end of the second connecting rod 33 to rotate on the fixing column 35. This causes the movable plate 34 to reciprocate up and down on the limit rail 36. The lifting and lowering of the movable plate 34 synchronously drives the connecting plate 37 to lift and lower, and drives the interval assembly to lift and lower. The motor 31 drives the movable plate 34 to move up and down, driving the connecting plate 37 and the interval assembly to lift and lower as a whole. The lifting and lowering range of the movable plate 34 can cover the test objects of various thicknesses, enhancing the versatility of the equipment.

[0036] The working principle is as follows:

[0037] During testing, the operator rotates the threaded rod 23 clockwise, causing the fixed block 25 to move downwards. The movement of the fixed block 25 synchronously moves the lifting plate 24 downwards. Under the constraint of the inclined groove 241, the limiting rod 26 moves to both sides within the inclined groove 241, causing the ultrasonic thickness gauge 15 to move on both sides of the outer surface of the limiting post 27. Simultaneously, the thickness probe 16 moves to both sides. The operator then rotates the threaded rod 23 counterclockwise, causing the fixed block 25 to move upwards. Under the constraint of the inclined groove 241, the limiting rod 26 moves towards the center within the inclined groove 241, causing the ultrasonic thickness gauge 15 to move towards the center of the outer surface of the limiting post 27. Through threaded transmission, the limiting function of the inclined groove 241, and synchronous movement, precise control can be achieved. The thickness probe 16 is positioned left and right to adapt to the thickness measurement needs of different detection points, improving the accuracy of measurement data. During detection, the controller 12 starts the motor 31, which drives the first connecting rod 32 to rotate. The rotation of the first connecting rod 32 synchronously rotates one end of the second connecting rod 33, causing the other end of the second connecting rod 33 to rotate on the fixed column 35. This causes the movable plate 34 to reciprocate up and down on the limit rail 36. The lifting and lowering of the movable plate 34 synchronously drives the connecting plate 37 to lift and lower, and also drives the interval assembly to lift and lower. The motor 31 drives the movable plate 34 to move up and down, driving the connecting plate 37 and the interval assembly to lift and lower as a whole. The lifting and lowering range of the movable plate 34 can cover the measured objects of various thicknesses, enhancing the versatility of the equipment.
