Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of thickness gauges, and particularly relates to a coating thickness gauge with a temperature control function. BACKGROUND

[0002] In an industrial mechanical transmission system, gears are core power transmission components, and the surfaces of the gears are often sprayed with functional coatings such as wear-resistant, corrosion-resistant and friction-reducing coatings to improve the anti-wear capacity and prolong the service life. The actual effective thickness of the coating directly determines the protection performance and transmission reliability of the gear, and therefore, accurate detection of the thickness of the coating on the surface of the gear is a key quality control link in the whole process of gear manufacturing, assembly and operation and maintenance.

[0003] Most existing gear coating thickness detection technologies adopt a static measurement mode, that is, when a gear to be detected is in a static state, a coating thickness gauge is used to sample the thickness of the coating on the surface of the gear. However, the gear needs to be continuously rotated at a high speed in an actual working condition, and during the rotation, the coating will be stretched along the radial direction of the gear due to the centrifugal force, resulting in a change in the actual effective thickness of the coating compared with the static state, for example, the coating is stretched along the circumferential direction and the radial direction of the gear, and the thickness of a local area is thinned. At this time, the thickness data obtained by static measurement deviates from the actual coating thickness of the gear when the gear is running. If the static detection result is used to determine whether the coating meets the design requirements, a misjudgment may occur. For example, the coating thickness measured in the static state meets the standard, but the thickness is reduced to below the safety threshold due to the centrifugal force during running, thereby causing problems such as premature failure of the gear coating and excessive wear of the gear surface.

[0004] However, the traditional coating thickness gauge cannot effectively test the high-speed rotating gear. The traditional coating thickness gauge needs to be held by a worker close to the high-speed rotating gear, and the probe of the magnetic and eddy current coating thickness gauge needs to be stably attached to the high-speed rotating gear at all times. However, when the worker holds the probe of the magnetic and eddy current coating thickness gauge and contacts the gear, friction will be generated between the probe and the gear, causing damage. The sound wave emission and receiving path of the ultrasonic thickness gauge will also be offset due to the high-speed movement of the gear, resulting in interruption of the detection signal or severe fluctuation of the data, and it is difficult to obtain continuous and accurate thickness detection results. SUMMARY

[0005] The purpose of the present application is to provide a coating thickness gauge with a temperature control function to solve the technical problems in the prior art that when a high-speed rotating gear is tested, the worker holds a magnetic and eddy current thickness gauge, the probe of which needs to be stably attached to the gear, but is easily damaged due to friction; the sound wave path of the ultrasonic thickness gauge is offset due to the high-speed movement of the gear, resulting in interruption of the detection signal, fluctuation of the data, and difficulty in obtaining continuous and accurate results.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0007] A coating thickness gauge with temperature control function includes a working box with temperature control function, a drive adjustment mechanism installed inside the working box, a detection mechanism installed on the drive adjustment mechanism, and a spur gear. The detection mechanism includes a detection protection component, which includes: a coating thickness gauge body for measuring the actual effective thickness of the coating on the surface of the spur gear in a rotating state, with a fixing ring fixedly mounted on it, and the coating thickness gauge body rotating synchronously with the spur gear to match the actual operating conditions of the spur gear; multiple mounting seats, all slidably mounted inside the fixing ring, the mounting seats being connected to the fixing ring via a first spring; and ball bearings, rollingly mounted inside the mounting seats. When the drive adjustment mechanism controls the coating thickness gauge body to engage with the spur gear, the ball bearings first make rolling contact with the spur gear and buffer it, ensuring that the synchronously rotating coating thickness gauge body and the spur gear complete flexible engagement before rigid collision, thus protecting the coating thickness gauge body.

[0008] Preferably, the drive adjustment mechanism includes: a mounting plate, fixedly mounted on the work box, with a motor fixedly mounted on its bottom; and a drive shaft, fixedly mounted on the power output shaft of the motor, on which a spur gear is mounted, and the spur gear is fixed by a threaded fixing nut.

[0009] Preferably, the detection mechanism further includes: a fixed box with threaded grooves on the bottom and left and right sides; a second movable frame slidably installed inside the fixed box, with an electric telescopic rod fixedly installed on its bottom; and a first movable frame fixedly connected to the telescopic end of the electric telescopic rod and fixedly connected to the coating thickness gauge body.

[0010] Preferably, the detection mechanism further includes a transmission assembly, which includes a drive frame connected to the first movable frame via two telescopic columns, and a row of locking teeth fixedly installed inside the drive frame.

[0011] Preferably, the detection mechanism further includes a one-way rotation component, which includes: a reciprocating lead screw, rotatably mounted inside the fixed box and threadedly connected to the second movable frame; and a fixed frame, fixedly mounted inside the fixed box and rotatably connected to the reciprocating lead screw, with a slide rod slidably connected to the drive frame fixedly mounted at its bottom.

[0012] Preferably, the unidirectional rotation assembly further includes: a second gear, which has an internal actuating plate and a rotating column fixedly mounted on the left side and rotatably connected to the fixed box; and a mounting plate, which is fixedly connected to the actuating plate on one side and to the reciprocating lead screw on the other side.

[0013] Preferably, the detection and protection assembly further includes: a grinding rod, which is slidably mounted on the fixed ring and connected to the fixed ring via a second spring; wherein, under the thrust of the second spring, the grinding head at the end of the grinding rod is continuously in contact with the surface of the ball.

[0014] Preferably, the drive adjustment mechanism further includes an adjustment component, which includes: a rotating disk fixedly mounted on the drive shaft, on which a gear ring is rotatably mounted; a first rotating shaft rotatably mounted on the rotating disk, on which a first gear meshing with the gear ring is fixedly mounted; and multiple support plates, all fixedly mounted on the gear ring.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] 1. In this invention, when the driving adjustment mechanism drives the coating thickness gauge body close to the spur gear, the ball first forms rolling contact with the rotating spur gear; at the same time, the first spring provides elastic buffer for the ball through the mounting seat, avoiding direct rigid collision between the coating thickness gauge body and the spur gear, which reduces the wear of the coating thickness gauge body and prevents scratches on the coating surface of the spur gear, ensuring the integrity of the components and the accuracy of the test during the test.

[0017] 2. This invention utilizes a silicone sheet fixedly mounted on the coating thickness gauge body. After the driving adjustment mechanism brings the coating thickness gauge body into contact with the spur gear, the silicone sheet can accommodate any protrusions or shallow depressions that may exist on the surface of the spur gear. When there is a protrusion at the contact point, the silicone sheet uses its own elasticity to alleviate the pressure of the protrusion on the coating thickness gauge body, preventing damage to the thickness gauge. When there is a shallow depression at the contact point, the silicone sheet is compressed to fill the depression, eliminating the gap between the coating thickness gauge body and the spur gear, ensuring that the thickness gauge can stably collect coating thickness data and improving detection accuracy.

[0018] 3. In this invention, the rotating disk of the adjusting component is fixed to the drive shaft, the gear ring is rotatably mounted on the rotating disk, and the support plate is fixed to the gear ring. When the detection mechanism is bolted to the support plate, rotating the first rotating shaft can drive the first gear meshing gear ring to rotate, thereby causing the support plate to drive the detection mechanism to adjust its position around the spur gear. At the same time, the electric telescopic rod in the detection mechanism drives the coating thickness gauge body to move, and combined with the unidirectional rotation component, drives the coating thickness gauge body to switch detection points, ultimately realizing the detection of coating thickness in different areas such as the tooth surface, tooth groove, and tooth end of the spur gear, and comprehensively evaluating the quality of the gear coating.

[0032] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0035] This invention is described in detail with reference to the accompanying drawings. When detailing the embodiments of this invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not to scale. Furthermore, the accompanying drawings are merely examples and should not be construed as limiting the scope of protection of this invention.

[0036] Furthermore, it should be noted in the description of this invention that the terms "first," "second," or "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] Unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" in this invention should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; similarly, they can refer to mechanical connections, electrical connections, or direct connections, or indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] Example 1: As Figures 1 to 11 As shown, a coating thickness gauge with temperature control function includes a working box 100 with temperature control function, a drive adjustment mechanism 200 installed inside the working box 100, a detection mechanism 300 installed on the drive adjustment mechanism 200, and a spur gear 400. The detection mechanism 300 includes a detection protection component 310, which includes: a coating thickness gauge body 314 for measuring the actual effective thickness of the coating on the surface of the spur gear 400 when it is rotating, and a fixing ring 311 is fixedly installed on it. The coating thickness gauge body 314 rotates synchronously with the spur gear 400. To match the actual operating conditions of the spur gear 400; multiple mounting seats 315 are slidably installed inside the fixed ring 311, and the mounting seats 315 are connected to the fixed ring 311 through the first spring 317; ball bearings 312 are rolled inside the mounting seats 315; wherein, when the drive adjustment mechanism 200 controls the coating thickness gauge body 314 to fit with the spur gear 400, the ball bearings 312 first roll and contact the spur gear 400 and buffer, ensuring that the synchronously rotating coating thickness gauge body 314 and the spur gear 400 complete flexible fitting before rigid collision, thus protecting the coating thickness gauge body 314.

[0039] It should be noted that the rotation of the spur gear 400 will generate centrifugal force on the coating. The coating on the spur gear 400 will change due to the continuous action of the centrifugal force, causing the coating on the spur gear 400 to have a stretching effect in the radial direction of the spur gear 400. The coating on the tooth surface, tooth end and tooth groove area of ​​the spur gear 400 needs to move in a circular motion with the spur gear 400. The centrifugal force will have an outward pulling effect on the coating, causing the coating to extend radially as a whole. This extension will further reduce the actual effective thickness of the coating compared to the static state.

[0040] The detection mechanism 300 is mounted on the drive adjustment mechanism 200, and the spur gear 400 can also be fixedly mounted on the drive adjustment mechanism 200. When the drive adjustment mechanism 200 starts running, it causes the spur gear 400 and the detection mechanism 300 to rotate synchronously. During rotation, the coating thickness gauge body 314 in the detection mechanism 300 is brought closer to the spur gear 400. The coating thickness gauge body 314 is equipped with ball bearings 312, which preferentially contact the spur gear 400. Since the ball bearings 312 can roll inside the mounting base 315, after contacting the spur gear 400, they roll along the gear, similar to a wheel rolling over the ground, creating rolling friction. The rolling friction is much smaller than the sliding friction of the coating thickness gauge body 314 directly pressing against the spur gear 400. The complete movement process is as follows: after the ball 312 rolls over the surface of the spur gear 400, the coating thickness gauge body 314 will continue to move until the fixing ring 311 and the coating thickness gauge body 314 itself also press against the spur gear 400. At this time, the ball 312 retracts into the fixing ring 311. Although the coating thickness gauge body 314 and the spur gear 400 are in direct contact at this point, the critical initial contact stage has been protected by the rolling friction of the coating thickness gauge body 314. The surfaces of the coating thickness gauge body 314 and the spur gear 400 have not been subjected to sliding friction, so wear can be greatly reduced.

[0041] The working chamber 100 is equipped with a heating module and a cooling module. The heating module and cooling module are used to change the temperature environment of the spur gear 400 and adjust the test environment temperature by means of the real-time temperature feedback from the temperature monitoring instrument, so as to realize the coating thickness detection of the spur gear 400 at different temperatures.

[0042] like Figure 1 and Figure 2 As shown, the drive adjustment mechanism 200 includes a drive assembly 210, which includes a mounting plate 211, a drive shaft 212, a fixing nut 213, and a motor 214.

[0043] Mounting plate 211 is fixedly mounted on the work box 100, and motor 214 is fixedly mounted on the bottom of mounting plate 211; drive shaft 212 is fixedly mounted on the power output shaft of motor 214, and spur gear 400 is mounted on drive shaft 212. Drive shaft 212 fixes spur gear 400 by threaded fixing nut 213.

[0044] It should be noted that the drive shaft 212 has threads on its surface. The spur gear 400 is placed on the drive shaft 212, and then the spur gear 400 can be fixed by the fixing nut 213 connected to the drive shaft 212. Then the motor 214 is started, and the drive shaft 212 is rotated by the motor 214. Since the detection mechanism 300 is also fixedly installed on the drive shaft 212, the spur gear 400 and the detection mechanism 300 can rotate synchronously.

[0045] like Figure 5 and Figure 8 and Figure 11 The testing mechanism 300 also includes a moving component 320, which includes a first moving frame 321, a second moving frame 322, an electric telescopic rod 323, a fixing box 324, and a threaded groove 325.

[0046] The fixed box 324 has threaded grooves 325 on the bottom and left and right sides; the second movable frame 322 is slidably installed inside the fixed box 324, and an electric telescopic rod 323 is fixedly installed on the bottom of the second movable frame 322; the first movable frame 321 is fixedly connected to the telescopic end of the electric telescopic rod 323 and fixedly connected to the coating thickness gauge body 314.

[0047] It should be noted that a mounting hole is provided through the drive shaft 212. By aligning the threaded groove 325 on the fixed box 324 with the mounting hole on the drive shaft 212 and using bolts, the fixed box 324 can be fixed to the drive shaft 212. In this way, the fixed box 324 can rotate synchronously with the spur gear 400. When the fixed box 324 rotates synchronously with the spur gear 400, the electric telescopic rod 323 is activated. The electric telescopic rod 323 will move the first moving frame 321, which will move the coating thickness gauge body 314. In this way, the coating thickness gauge body 314 will come into contact with the spur gear 400, thereby detecting the coating condition of the spur gear 400 under high-speed rotation.

[0048] like Figures 9 to 11 The testing mechanism 300 also includes a transmission assembly 330, which includes a drive frame 331, a telescopic column 332, and a locking tooth 333.

[0049] The drive frame 331 is connected to the first movable frame 321 via two telescopic columns 332, and a row of locking teeth 333 is fixedly installed inside the drive frame 331.

[0050] The testing mechanism 300 also includes a one-way rotation assembly 340, which includes a rotating column 341, a second gear 342, a toggle plate 343, a mounting plate 344, a fixing frame 345, a reciprocating lead screw 346, and a slide bar 347.

[0051] A reciprocating lead screw 346 is rotatably installed inside a fixed box 324 and is threadedly connected to a second movable frame 322. A fixed frame 345 is fixedly installed inside a fixed box 324 and is rotatably connected to the reciprocating lead screw 346. A slide rod 347 that is slidably connected to a drive frame 331 is fixedly installed at the bottom of the fixed frame 345. A toggle plate 343 is provided inside the second gear 342. A rotating column 341 that is rotatably connected to the fixed box 324 is fixedly installed on the left side of the second gear 342. One side of the mounting plate 344 is fixedly connected to the toggle plate 343, and the other side of the mounting plate 344 is fixedly connected to the reciprocating lead screw 346.

[0052] The actuating piece 343 is a ratchet-type one-way actuating structure that engages with the ratchet on the second gear 342. When the coating thickness gauge body 314 approaches the spur gear 400, the locking teeth 333 drive the second gear 342 to rotate in the forward direction, and the actuating piece 343 idles without driving the second gear 342. When the coating thickness gauge body 314 moves away from the spur gear 400, the second gear 342 rotates in the reverse direction, and the actuating piece 343 engages the ratchet, driving the spur gear 400 and the reciprocating screw 346 to rotate.

[0053] It should be noted that when the electric telescopic rod 323 moves the first moving frame 321 and the coating thickness gauge body 314 upward, it also moves the drive frame 331 and the locking gear 333 upward via the telescopic column 332. Due to the tooth groove on the second gear 342, although the locking gear 333 meshes with the second gear 342 and can make the second gear 342 rotate, the second gear 342 will not drive the reciprocating screw 346 to rotate via the actuating plate 343 and the mounting plate 344. In this way, the coating thickness gauge body 314 will only move upward to contact the spur gear 400 and detect the coating on the spur gear 400. After the coating thickness gauge body 314 has completed the coating detection on the spur gear 400, the electric telescopic rod 323 can be controlled to move the coating thickness gauge body 314 away from the spur gear 400. The locking teeth 333 on the moving frame 331 will act on the second gear 342, causing the second gear 342 to rotate. However, this time, the rotation of the second gear 342 will cause the actuating plate 343 to drive the mounting plate 344 to rotate. The mounting plate 344 will drive the reciprocating screw 346 to rotate. The rotation of the reciprocating screw 346 will cause the second moving frame 322 to move. As a result, the coating thickness gauge body 314 and the electric telescopic rod 323 mounted on the second moving frame 322 will move. In this way, the coating thickness gauge body 314 will move to other positions of the spur gear 400 to inspect the coating at other positions of the spur gear 400. Regardless of which part of the spur gear 400 is inspected, the ball bearings 312 can reduce the friction between the coating thickness gauge body 314 and the spur gear 400, thereby reducing the damage to the coating thickness gauge body 314.

[0054] Furthermore, a silicone sheet 313 can be fixedly installed on the coating thickness gauge body 314. The specific installation location depends on the surface smoothness of the spur gear 400. Since the surface of the spur gear 400 is not necessarily smooth without any protrusions or depressions, when the coating thickness gauge body 314 contacts the spur gear 400, there may be a protrusion at the contact point. In this case, the silicone sheet 313 will protect the coating thickness gauge body 314 from the pressure of the protrusion on the spur gear 400, thus preventing damage to the coating thickness gauge body 314. When there is a shallow depression at the contact point, the silicone sheet 313 will fill the shallow depression of the spur gear 400 due to compression. In this way, there will be no gap between the coating thickness gauge body 314 and the spur gear 400, which can better detect the coating of the spur gear 400.

[0055] When the coating thickness gauge body 314 comes into contact with the spur gear 400, the friction mode is changed by the action of the ball bearing 312, turning the sliding friction between the coating thickness gauge body 314 and the spur gear 400 into rolling friction. Then, the silicone sheet 313 can further reduce the friction between the coating thickness gauge body 314 and the spur gear 400, and further protect the coating thickness gauge body 314.

[0056] Example 2: As Figure 6 and Figure 7 As shown, while all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0057] The detection protection component 310 also includes a retaining ring 311, a ball bearing 312, a silicone sheet 313, a coating thickness gauge body 314, a mounting base 315, a grinding rod 316, a first spring 317, and a second spring 318.

[0058] The grinding rod 316 is slidably mounted on the fixed ring 311, and the grinding rod 316 is connected to the fixed ring 311 through the second spring 318; wherein, under the thrust of the second spring 318, the grinding head at the end of the grinding rod 316 is continuously in contact with the surface of the ball 312.

[0059] It should be noted that when the ball 312 comes into contact with the spur gear 400, the ball 312 will rub against the spur gear 400. Over time, an oxide layer will form on the surface of the ball 312, affecting subsequent rolling assistance. The grinding rod 316, under the action of the second spring 318, always keeps in contact with the ball 312. When the ball 312 rolls, it rubs against the grinding rod 316 to remove the surface oxide layer and prevent the oxide layer from affecting the rolling assistance of the ball 312.

[0060] Example 3: As Figure 2 and Figure 3As shown, while all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0061] The drive adjustment mechanism 200 also includes an adjustment component 220, which includes a support plate 221, a gear ring 222, a first rotating shaft 223, a first gear 224, and a rotating disk 225.

[0062] A rotating disk 225 is fixedly mounted on a drive shaft 212, and a gear ring 222 is rotatably mounted on the rotating disk 225; a first rotating shaft 223 is rotatably mounted on the rotating disk 225, and a first gear 224 that meshes with the gear ring 222 is fixedly mounted on the first rotating shaft 223; multiple support plates 221 are all fixedly mounted on the gear ring 222.

[0063] It should be noted that since the detection mechanism 300 is connected to the drive shaft 212 by bolts, and the support plate 221 also has mounting holes, the detection mechanism 300 can be installed on the support plate 221 by bolts. After the detection mechanism 300 is installed on the support plate 221, the coating thickness gauge body 314 is moved by the electric telescopic rod 323 and will contact the tooth end of the spur gear 400, thus detecting the coating condition at the tooth end of the spur gear 400.

[0064] By rotating the first shaft 223, the first gear 224 will rotate, which in turn will cause the gear ring 222 to rotate. The rotation of the gear ring 222 will cause the support plate 221 to rotate around the spur gear 400. As a result, the detection mechanism 300 connected to the support plate 221 will also rotate. This will allow the coating thickness gauge body 314 to be aligned with different positions of the spur gear 400, such as the tooth groove or the side wall of the tooth groove. This allows for multi-directional detection of the coating condition at different locations under high-speed rotation, thereby determining whether the coating spraying is reasonable.

[0065] Working principle: After the motor 214 starts, the power is transmitted to the drive shaft 212 through the output shaft, which drives the drive shaft 212 to rotate; the spur gear 400 is fixed on the drive shaft 212 by the fixing nut 213 and rotates synchronously with the drive shaft 212 at high speed, simulating the actual running state of the gear; at the same time, the fixing box 324 is fixed to the mounting hole of the drive shaft 212 by bolts passing through the threaded groove 325, so that the detection mechanism 300 rotates synchronously with the drive shaft 212 and the spur gear 400, providing a basis for dynamic detection of coating thickness.

[0066] When the electric telescopic rod 323 is activated, the telescopic end pushes the first moving frame 321 to move, causing the coating thickness gauge body 314 to approach the spur gear 400. During this process, the ball bearing 312 first makes rolling contact with the rotating spur gear 400, and the mounting base 315 slides along the fixing ring 311 and compresses the first spring 317. The first spring 317 provides elastic buffering to avoid rigid collision between the coating thickness gauge body 314 and the spur gear 400. Subsequently, the coating thickness gauge body 314 continues to move until it fits against the spur gear 400. The silicone sheet 313 adapts to the protrusions or depressions on the gear surface to ensure that the thickness gauge stably collects the actual effective thickness data of the coating under rotating conditions.

[0067] Detection position switching drive: When other positions of the spur gear 400 need to be detected, the electric telescopic rod 323 retracts, causing the first moving frame 321 and the coating thickness gauge body 314 to move away from the spur gear 400; the first moving frame 321 drives the drive frame 331 to move through the telescopic column 332, and the locking teeth 333 inside the drive frame 331 mesh with the second gear 342, causing the second gear 342 to rotate around the rotating column 341; the actuating plate 343 inside the second gear 342 pushes the mounting plate 344 to rotate, and the mounting plate 344 drives the reciprocating screw 346 to rotate around the fixed frame 345; the reciprocating screw 346 is threadedly engaged with the second moving frame 322, driving the second moving frame 322 to slide along the slide bar 347, thereby causing the electric telescopic rod 323 and the coating thickness gauge body 314 to switch detection positions, realizing multi-area detection.

[0068] The working box 100 contains a transmission gear that meshes with the spur gear 400. When the spur gear 400 rotates, it meshes with the transmission gear to transmit power. During the meshing friction process, the gear accumulates heat, creating different temperature environments. The temperature monitoring instrument inside the working box 100 monitors the ambient temperature of the spur gear 400 in real time, providing temperature data support for analyzing the coating state at different temperatures.

[0069] During the rolling process of ball 312, the grinding rod 316 is always in contact with ball 312 under the thrust of the second spring 318. When ball 312 rotates, it rubs against grinding rod 316 to remove the oxide layer on the surface of ball 312, ensuring smooth rolling of ball 312 and maintaining the soft contact buffering effect.

[0070] When it is necessary to inspect the tooth grooves, tooth ends, and other positions of the spur gear 400, the inspection mechanism 300 is installed on the mounting hole of the support plate 221 by bolts; the first rotating shaft 223 is rotated, which drives the first gear 224 to rotate, and the first gear 224 meshes with the gear ring 222, causing the gear ring 222 to rotate around the rotating disk 225; the gear ring 222 drives the support plate 221 and the inspection mechanism 300 to adjust the angle around the spur gear 400, and combined with the electric telescopic rod 323 to drive the coating thickness gauge body 314 to move, so as to realize the coating thickness inspection of the spur gear 400 in different positions.
