Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0035] Reference Figures 1 to 2 This utility model provides a coating thickness measuring fixture, including a measuring component 100, a guiding component 200, a supporting component 300, and a sliding component 400. The measuring component 100 is used to measure the coating thickness of the product 500 to be measured; the guiding component 200 is used to guide the measuring component 100; the supporting component 300 is used to place the product 500 to be measured for measurement; and the sliding component 400 is used to adjust the position of the supporting component.

[0036] It should be noted that the product to be measured, 500, is a tubular structural component of the rubber joint of a hydraulic shock absorber. Of course, the product to be measured, 500, can also be other tubular structural components for which the thickness of the adhesive coating on a metal substrate needs to be measured. In actual design, the product to be measured, 500, can be selected for measurement according to the requirements.

[0037] Reference Figures 3 to 4 In some embodiments, the measuring component 100 includes a probe 110 and a mounting plate 120. One end of the probe 110 is used to extend into the interior of the product 500 to be measured for measurement, and the other end of the probe 110 is connected to the mounting plate 120. The probe 110 is used to measure the coating thickness of the product 500. The guiding component 200 includes a plurality of guide posts 210, which penetrate the mounting plate 120 in a vertical direction. The mounting plate 120 is movable along the axial direction of the guide posts 210.

[0038] During use, one end of the probe 110 can extend into the tubular structure of the rubber joint of the hydraulic shock absorber. Compared to traditional probes, the probe 110 is not limited by excessively small tube diameters or internal arc structures, allowing it to reach the measurement position and solving the problem of traditional probes being difficult to penetrate deeply. Furthermore, the guide assembly 200 includes several guide posts 210 penetrating the mounting plate 120. The mounting plate 120 can move axially along the guide posts 210. During measurement, the guide posts 210 provide guidance and stable support for the mounting plate 120 and the probe 110. When the probe 110 extends into the tubular structure, as the mounting plate 120 moves along the guide posts 210, the guide posts 210 limit its sway and offset, ensuring that the probe 110 maintains a stable posture and position during measurement. This avoids large errors in measurement data due to unstable probe positioning, thereby improving the accuracy and reliability of the measurement. In addition, the synchronous movement of the probe 110 and the mounting plate 120 makes the measurement operation more convenient and efficient. Operators do not need to frequently adjust the position and angle of the probe during measurement, reducing operational difficulty, saving measurement time, and improving measurement efficiency.

[0039] Reference Figure 2 , Figure 4In some embodiments, the probe 110 includes a base 111 and a measuring part 112 perpendicularly disposed to the base 111. One end of the base 111 is connected to the measuring part 112, and the other end of the base 111 is connected to the mounting plate 120. Specifically, the base 111 is perpendicularly disposed to the measuring part 112, allowing the measuring part 112 to penetrate vertically into the interior of the product 500 to be measured, addressing the challenges of small pipe diameters and numerous internal arcs, thus broadening the applicability of the measurement. Furthermore, by connecting to the mounting plate 120, the base 111 can transfer the stable support of the mounting plate 120 to the measuring part 112 when the measuring part 112 penetrates into the product to perform measurement work, limiting its swaying and offset during the measurement process, ensuring that the measuring part 112 maintains the measurement angle and positional relationship with the inner surface of the product 500 to be measured, avoiding measurement errors caused by probe 110 instability, and improving the reliability of the measurement data.

[0040] In some embodiments, the measuring part 112 of the probe 110, away from the base 111, is connected to a magnetic thickness gauge (not shown), thereby facilitating the measurement of the coating thickness of the product 500 to be measured. During the measurement process, the measuring part 112 is moved to the measurement position by manipulating the probe 110 and its connected mounting plate 120 and other components, and then the measurement is completed by the magnetic thickness gauge connected to the measuring part 112, reducing the difficulty of operation and making the measurement process simpler and more efficient.

[0041] It should be noted that the use of a magnetic thickness gauge to measure the coating thickness of the product 500 is existing technology, and this utility model has not made any improvements to this part, so its principle and process will not be described in detail.

[0042] Reference Figure 3 , Figure 4 In some embodiments, the mounting plate 120 is provided with a mounting groove 121, and at least a portion of the base 111 is disposed in the mounting groove 121, thereby increasing the contact area between the two, limiting the displacement and shaking of the probe 110, ensuring that the connection between the probe 110 and the mounting plate 120 is firm and reliable, and thus ensuring the stability and continuity of the measurement work.

[0043] Specifically, the length direction of the mounting groove 121 is parallel to the length direction of the base 111, and a portion of the base 111 is disposed within the mounting groove 121, allowing the probe 110 to move synchronously with the mounting plate 120. During the measurement process, when the mounting plate 120 moves axially along the guide post 210, the probe 110 can move with the mounting plate 120 because the base 111 and the mounting groove 121 are parallel and engaged, avoiding relative sliding or misalignment. This ensures that the probe 110 can accurately reach the measurement position, guaranteeing the accuracy and consistency of the measurement operation, avoiding measurement errors caused by asynchronous movement of the probe 110 and the mounting plate 120, and improving the reliability of the measurement results.

[0044] Reference Figure 3 , Figure 4 In some embodiments, the measuring assembly 100 further includes a mounting block 130 and a connector 140. The mounting block 130 is disposed on the top of the mounting plate 120 and has a first mounting hole. The mounting block 130 is located at the opening of the mounting groove 131. The mounting plate 120 has a corresponding second mounting hole. One end of the connector 140 passes through the first mounting hole and engages with the second mounting hole to confine the base 111 within the mounting groove 131. The connector 140 connects the mounting block 130, the mounting plate 120, and the base 111 within the mounting groove 121. When the probe 110 is subjected to resistance or external impact from the internal structure of the product 500 to be measured, it ensures that there is no relative displacement between the probe 110 and the mounting plate 120, thereby maintaining the stability of the overall structure of the measuring assembly 100, ensuring the normal operation of the measurement work, and avoiding measurement errors or equipment failures due to loose connections.

[0045] Reference Figure 3 , Figure 4 Furthermore, the corresponding arrangement of the first and second mounting holes provides a positioning reference for the installation of the connector 140. During assembly, the connector 140 can pass through the two mounting holes, thereby determining the relative positions between the mounting block 130, the mounting plate 120, and the base 111 of the probe 110. This ensures the accurate installation position of the probe 110 on the mounting plate 120, reduces measurement deviations caused by assembly errors, and improves the accuracy and reliability of the measurement results.

[0046] Alternatively, the connector 140 can be designed as a bolt, with both the first and second mounting holes being threaded holes, and the connector 140 being threadedly connected to the first and second mounting holes. Of course, the connector 140 can also be designed to be plugged into or snap-fitted into the first and second mounting holes. In actual design, the connection method between the connector 140 and the first and second mounting holes can be designed according to actual needs.

[0047] It should be noted that in some other embodiments, the probe 110 and the mounting plate 120 can be directly connected through the connector 140, or the probe 110 and the mounting plate 120 can be snapped or fixedly connected, which is not limited here.

[0048] Reference Figure 3In some embodiments, the support assembly 300 includes a base plate 310 and a support base 320. The support base 320 and guide posts 210 are respectively disposed on the base plate 310. The support base 320 is used to support the product to be measured 500, facilitating the measurement assembly 100 to measure the coating thickness of the product to be measured 500. In addition, the support base 320 and the guide posts 210 are arranged sequentially along the length direction of the probe 110. The bottoms of several guide posts 210 are connected to the base plate 310, providing sufficient space for the movement of the measurement assembly 100, facilitating the probe 110 to extend into the product to be measured 500.

[0049] Reference Figure 5 , Figure 6 In some embodiments, the upper surface of the support base 320 is provided with a V-groove 321 to limit the measurement of the product 500. Specifically, the top of the support base 320 is provided with a first limiting part 322 and a second limiting part 323, which are symmetrically arranged. The first limiting part 322 has a first inclined surface, and the second limiting part 323 has a second inclined surface, forming a V-groove 321 between the first and second inclined surfaces. When the product 500 to be measured is placed in the V-groove 321, the first limiting part 322 and the second limiting part 323 can limit the product 500 to be measured, preventing it from falling off the support base 320, avoiding measurement failure or data deviation due to displacement, and improving the stability and reliability of the measurement process. In addition, the V-groove 321 can accommodate measurement of products 500 of different specifications, improving applicability. For products 500 of different specifications, the first inclined surface and the second inclined surface can form contact with the surface of the product 500, and stable support can be achieved by adjusting the position of the contact point.

[0050] Reference Figure 6 In some embodiments, a baffle 324 is provided between the first inclined surface and the second inclined surface, and the baffle 324 is located on the side of the support 320 away from the measuring component 100, which can further limit the measuring component 100. During measurement, for the product 500 whose inner sidewall is arc-shaped, it is necessary to measure the lowest point of the inner sidewall of the product 500. Therefore, before starting the measurement, several sets of data need to be measured to find the lowest point of the inner sidewall of the product 500. Specifically, the product 500 is placed in the V-groove 321 of the support 320, and one end of the product 500 is abutted against the baffle 324. Then, the product 500 is rotated so that the probe 110 measures different positions of the inner sidewall of the product 500, thereby determining the lowest point of the inner sidewall of the product 500 based on the measurement results.

[0051] In some embodiments, the central axis of the support 320 is collinear with the central axis of the probe 110, enabling the probe 110 to move precisely along the central path of the product 500 when it is inserted into the product to be measured to measure the coating thickness, thus avoiding measurement errors caused by deviations in the contact position of the probe 110. Furthermore, operators do not need to repeatedly adjust the relative positions of the product 500 and the probe 110 before measurement, reducing operational difficulty, saving preparation time, and improving measurement efficiency.

[0052] Reference Figure 2 , Figure 3 In some embodiments, the guide assembly 200 further includes a locking member 220. The mounting plate 120 has a first locking hole, and the guide post 210 has a corresponding second locking hole. One end of the locking member 220 passes through the first locking hole and engages with the second locking hole to lock the mounting plate 120, thereby preventing the mounting plate 120 from moving along the axial direction of the guide post 210. When the coating measuring fixture is not in use, the locking member 220 is passed through the first locking hole and engages with the second locking hole to lock the mounting plate 120. At this time, the mounting plate 120, along with the probe 110, remains in a preset position, preventing movement of the mounting plate 120 due to accidental contact, handling vibration, or other factors, and preventing damage to the probe 110 or displacement of the measuring fixture components. When the coating measuring fixture is in use, the operator simply removes the locking member 220, and the mounting plate 120, under the action of gravity, allows the probe 110 to slide freely along the axial direction of the guide post 210, thereby measuring the coating thickness of the product 500 to be measured.

[0053] In some embodiments, the locking member 220 can be designed as a wing screw, with both the first locking hole and the second locking hole being threaded holes, and the locking member 220 being threadedly connected to the first locking hole and the second locking hole. Of course, in actual design, the structure of the locking member 220 can be designed according to the actual situation.

[0054] Reference Figure 2 , Figure 3 In some embodiments, there are four guide posts 210 to improve the stability of the moving mounting plate 120. Of course, the guide posts 210 can also be designed as one, two, three, or six. In actual design, the number of guide posts 210 can be designed according to actual needs. In addition, the two guide posts 210 closest to the support base 320 are connected to locking members 220. Of course, it is also possible to design that all four guide posts 210 are connected to locking members 220. In actual design, the number of locking members 220 can be designed according to actual needs.

[0055] In some embodiments, the guide assembly 200 further includes buffer pads 230 corresponding to the guide posts 210. The buffer pads 230 are fitted over the outer side of the corresponding guide posts 210, and their bottoms are connected to the base plate 310 to prevent damage to the probe 110 caused by sudden descent. Specifically, the buffer pads 230 form an elastic buffer layer between the mounting plate 120 and the base plate 310. When the probe 110 descends near its limit or experiences an unexpected rapid drop, the buffer pads 230 absorb the impact force through their elastic deformation, transforming rigid collisions into flexible buffering, reducing damage to the probe 110, extending the service life of the measuring assembly 100, and reducing equipment maintenance and replacement costs. Furthermore, the buffer pads 230 are made of rubber; however, in actual design, the material of the buffer pads 230 can be designed according to actual needs.

[0056] Reference Figure 2 , Figure 3 In some embodiments, the guide assembly 200 further includes a guide sleeve 240. The mounting plate 120 is provided with guide holes corresponding to the guide posts 210, and at least one guide hole contains a guide sleeve 240. The guide sleeve 240 is fitted onto the outer side of the corresponding guide post 210 and can slide along the axial direction of the corresponding guide post 210. During the up-and-down movement of the probe 110 with the mounting plate 120, the guide sleeve 240 slides along the axial direction of the guide post 210, limiting the movement trajectory of the mounting plate 120, thereby preventing the probe 110 from wobbling and causing inaccurate measurement results, and improving the accuracy of coating thickness measurement. Specifically, the guide sleeve 240 is a ball bearing sleeve, which can reduce the friction between the guide sleeve 240 and the guide post 210, making the guide sleeve 240 slide more smoothly along the axial direction of the guide post 210. In addition, the guide sleeve 240 can be fitted onto the outer side of two guide posts 210, or the guide sleeve 240 can be provided on the outer side of each guide post 210, making the movement of the mounting plate 120 more stable.

[0057] Reference Figure 3 In some embodiments, the sliding assembly 400 includes a slide rail 410 and a slider 420. The base plate 310 has a sliding groove, the slide rail 410 is disposed within the sliding groove, and the slider 420 is disposed at the bottom of the support base 320. The slide rail 410 and the slider 420 are slidably connected, facilitating adjustment of the position of the support base 320, thereby adjusting the measurement position of the product 500 to be measured and ensuring smooth operation. Specifically, the sliding direction of the slider 420 along the slide rail 410 is the same as the length direction of the probe 110, ensuring that the moving direction of the support base 320 matches the measurement path of the probe.

[0058] When using the coating measurement fixture, firstly, the magnetic thickness gauge is zeroed and calibrated using a calibration plate. Then, the product to be measured 500 is placed on the support base 320, and the position of the support base 320 is adjusted by the sliding component 400 so that the measuring part 112 of the probe 110 extends into the product to be measured 500. Next, the mounting plate 120 is held by hand, and the locking piece 220 is removed. Then, the mounting plate 120 is released by hand, so that the mounting plate 120 drives the probe 110 to slide freely along the axis of the guide post 210 under the action of gravity. After the probe 110 contacts the product to be measured 500 and is in place, the magnetic thickness gauge will display the measurement result of the coating thickness.

[0059] It should be noted that using calibration plates to zero and calibrate a magnetic thickness gauge is an existing technology, and this invention has not made any improvements to this part, so its principle and process will not be described in detail.

[0060] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
