Description

Technical Field

[0001] The utility model relates to the technical field of magnetic product processing, in particular to a coating adhesion detection device. Background Art

[0002] Magnetic materials are usually used as matching structures in the fields of mechanics, electronics, etc. For example, they cooperate with the coil in the motor to realize the rotation of the main shaft. They are the key structure to ensure the normal operation of the equipment.

[0003] At present, due to the differences in the use environment of many equipment using magnetic materials, for some equipment in poor use environments such as high temperature and humidity, the magnetic materials inside are usually plated on their surfaces, and there are many types of plating on the market, including black-yellow oxide plating, nickel plating, copper-nickel plating, etc., and the protection of magnetic materials is achieved through plating, such as anti-corrosion and anti-rust of neodymium iron boron magnetic materials, so as to ensure the use performance and life of magnetic materials. However, due to the arrangement of the plating, when using the existing magnetic materials, if the bonding force between the plating and the magnetic material body is poor, there is a risk of plating falling off. Once the plating falls off and falls into the core precision space of the equipment, it is very easy to cause safety risks such as jamming, wear, and short circuit, which will affect the normal use of the equipment at the least, and cause direct damage to the equipment at the worst. Therefore, when manufacturing the magnetic materials with plating, it is necessary to consider whether the size of the bonding force of the plating on the magnetic material meets the design requirements. After the product processing is completed, it is necessary to sample and collect some magnetic materials with plating for testing, and judge whether the plating on the batch of magnetic materials is qualified through testing. However, at present, there are no devices on the market for direct testing. The industry usually uses other existing testing equipment to conduct indirect testing, such as using salt spray equipment to test the oxidation time. Although it can also meet the testing needs, the indirect testing method has the disadvantages of long testing time, the test results cannot intuitively reflect the problem, and it is difficult to ensure the accuracy of the test results.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 2 The technical solution provided by the utility model is described in detail, but the following content is not intended to limit the utility model.

[0023] Figure 1 FIG. 1 is a structural diagram of an embodiment of a coating adhesion detection device of the utility model. Figure 1 As shown, the coating adhesion detection device provided in this embodiment includes: a frame 1, a friction head 3 and a sliding component 4.

[0024] Specifically, the frame 1 has a base frame 11 and a side frame 12. At this time, the base frame 11 is placed horizontally, and both ends of the base frame 11 are provided with side frames 12 arranged vertically upward. The side frames 12 form an upper support structure at both ends of the base frame 11, which provides a support and guide basis for the installation of the subsequent sliding assembly 4. In addition, a clamping station 2 is provided on the base frame 11 and between the two side frames 12. The test piece 6 is installed through the clamping station 2 to ensure the stability of the test piece 6 during the test, thereby ensuring the accuracy of the test result.

[0025] Specifically, the friction head 3 is arranged between the two side frames 12, so as to facilitate the subsequent movement guide of the friction head 3 and maintain the stability of the friction head 3 when it moves. In addition, the friction head 3 is located above the clamping station 2, and the friction head 3 slides back and forth between the two side frames 12, so that the friction head 3 can rub the to-be-detected part 6 clamped by the clamping station 2, and judge whether the bonding force of the coating on the to-be-detected part 6 meets the design requirements by the number of frictions and the pressure applied during friction, so as to realize the direct detection of the bonding force of the coating, which is simple and convenient to operate, and the test results are intuitive and reliable, which not only improves the test efficiency, but also ensures the accuracy of the test results.

[0026] Specifically, the sliding assembly 4 is arranged between the side frame 12 and the friction head 3, and the sliding assembly 4 supports the friction head 3 and serves as a reciprocating sliding guide for the friction head 3, that is, the sliding assembly 4 is installed through the side frame 12, and the friction head 3 is supported and guided for movement by the sliding assembly 4, thereby maintaining the stability of the friction head 3 during testing and ensuring the accuracy of the test results.

[0027] Figure 2 This is a cross-sectional view of the installation of a pressure regulating assembly and a friction head in a preferred embodiment of the utility model. Figure 1 and Figure 2As shown, a pressure regulating assembly 5 is also provided between the friction head 3 and the sliding assembly 4. The pressure regulating assembly 5 is used to adjust the pressure applied to the friction head 3, and the friction force of the friction head 3 when rubbing the coating is changed to meet different test requirements. In addition, the pressure regulating assembly 5 also includes a sheath 51 and a plurality of counterweights 52. At this time, the sheath 51 is installed on the sliding assembly 4, so that the subsequent movement of the sheath 51 can be guided by the sliding assembly 4. At the same time, the sheath 51 has a cavity 511 arranged in a vertical direction, so that the arrangement direction of the cavity 511 is consistent with the direction of gravity, which provides conditions for the subsequent installation of the counterweight 52 in the cavity 511 and the counterweight 52 pressing the friction head 3. During installation, the upper end of the friction head 3 is extended from the lower end of the cavity 511 of the sheath 51 into the cavity 511, and the friction head 3 can slide in the cavity 511 of the sheath 51 in the vertical direction. During subsequent testing, a number of counterweights 52 can be selected according to the testing requirements and placed in the cavity 511. The counterweights 52 contact and press the upper end of the friction head 3, so that the gravity of the counterweights 52 can be applied to the friction head 3, thereby changing the friction force of the friction head 3 on the coating on the part to be tested 6, meeting different testing requirements and having better adaptability. Preferably, the sheath 51 is a cylindrical structure and is arranged in the vertical direction, so that the hollow of the sheath 51 can be directly used as the cavity 511, which is more convenient to process.

[0028] More specifically, the sliding assembly 4 disposed on the side frame 12 further includes a plurality of sliding rods 41. At this time, a long strip slide groove 121 arranged in the horizontal direction is provided on both side frames 12. The long strip slide groove 121 forms a guide groove on both side frames 12, providing a guide basis for the subsequent movement of the friction head 3. In addition, one end of a sliding rod 41 is slidably disposed in the long strip slide groove 121, and the other end of the sliding rod 41 is connected to the friction head 3. The sliding of the sliding rod 41 in the corresponding long strip slide groove 121 guides the movement of the friction head 3, and maintains the stability of the direction of the friction head 3 when it moves. It is worth pointing out that when a pressure regulating assembly 5 is installed between the sliding assembly 4 and the friction head 3, the other end of the sliding rod 41 connected to the friction head 3 is connected to the sleeve 51 on which the friction head 3 is installed. At this time, the sliding rod 41 can support the sleeve 51. At the same time, the sleeve 51 is used to guide the movement of the friction head 3. In addition, different numbers of counterweights 52 can be placed in the sleeve 51 to provide different pressures for the friction head 3, so that the friction force exerted by the friction head 3 on the coating of the test piece 6 is different, thereby meeting the testing requirements of different parameters of different products and having better adaptability. In addition, the sliding rod 41 is a bolt, and a threaded mounting hole is opened on the outer wall of the sleeve 51. The threaded end of the sliding rod 41 is connected to the threaded mounting hole, which makes disassembly and assembly more convenient. The cap head of the sliding rod 41 itself can be abutted against the side surface of the side frame 12 on the corresponding side, so that the length of the sliding rod 41 connected to the side frames 12 on both sides of the sleeve 51 cannot be changed, thereby avoiding the circumferential rotation of the sleeve 51, maintaining the stability of the sleeve 51 when driving the friction head 3 to move, and improving the accuracy of the test results.

[0029] More specifically, at least two long strip slides 121 are provided on each side frame 12. At this time, different long strip slides 121 on the same side frame 12 are located at different heights in the vertical direction and are arranged parallel to each other, so that the arrangement directions of different long strip slides 121 on the same side frame 12 are consistent, and multiple limit positions can be formed at different heights in the vertical direction, which provides conditions for preventing the friction head 3 from tilting and rotating in the future. At the same time, for the two side frames 12, the arrangement heights and directions of the long strip slides 121 on the two side frames 12 correspond one to one and are arranged symmetrically with respect to the friction head 3, ensuring that the force exerted by the two side frames 12 on the friction head 3 is consistent. During installation, a sliding rod 41 is provided in each long strip slide 121, so that the sliding assembly 4 can have multiple contact points with the two side plates, further ensuring the stability of the friction head 3 test. It is worth pointing out that the sliding rods 41 of different heights are respectively connected to the upper and lower ends of the sleeve 51, so that the sleeve 51 can be restricted at multiple points, thereby ensuring that the sleeve 51 will not tilt in the vertical direction, thereby maintaining the vertical state of the friction head 3, so that the friction head 3 can maintain a stable contact area to rub the coating on the test piece 6, thereby ensuring the accuracy of the test structure.

[0030] More specifically, the clamping station 2 on the base frame 11 includes a clamping block 21 and an adjusting rod 22. At this time, two moving grooves 111 are symmetrically opened on both sides of the base frame 11 with the friction head 3 as the center, and the two moving grooves 111 are arranged in the same straight line direction, ensuring that the two moving grooves 111 are facing each other. In addition, a clamping block 21 is arranged in each moving groove 111, and at the same time, an adjusting hole 122 is opened on each side frame 12, and an adjusting rod 22 is installed in each adjusting hole 122, and each adjusting rod 22 is abutted against the clamping block 21 in the moving groove 111 on the corresponding side. When in use, the part to be detected 6 is first placed between the two clamping blocks 21, and the two clamping blocks 21 are pushed closer or farther by the adjusting rod 22, so that the part to be detected 6 placed below the friction head 3 and between the two clamping blocks 21 can be clamped or loosened by the two clamping blocks 21, meeting the stable clamping of the part to be detected 6 during testing and the material unloading requirements after the test is completed.

[0031] More specifically, the adjustment rod 22 of the clamping station 2 is preferably a threaded rod, and the corresponding adjustment hole 122 on the side frame 12 is preferably a threaded hole. When installed, the adjustment rod 22 and the adjustment hole 122 are threadedly connected. When in use, the operator only needs to turn the adjustment rod 22 in the forward and reverse directions to adjust the position of the adjustment rod 22 relative to the side frame 12, thereby pushing and pulling the clamp block 21 to move, meeting the use requirements of clamping or loosening the to-be-detected part 6. Preferably, the two clamp blocks 21 are provided with matching holes on the opposite sides, and one end of the adjustment rod 22 is provided with an annular groove and inserted into the matching hole. A pin is installed on the clamp block 21 and one end extends into the matching hole and is inserted into the annular groove, which can prevent the adjustment rod 22 and the corresponding clamp block 21 from axial movement, so that the adjustment rod 22 can drive the clamp block 21 to move back and forth in the moving groove 111, and can also meet the use requirements of the adjustment rod 22 to rotate, and the structural design is more reasonable.

[0032] More specifically, the base frame 11 of the frame 1 is a flat plate structure. At this time, a concave detection cavity 123 is set in the middle area of ​​the base frame 11, so that the thickness of the two ends of the base frame 11 is greater than the thickness of the middle area, which provides sufficient material processing allowance for the processing of the movable groove 111. At this time, one end of the movable grooves 111 on both sides of the base frame 11 is connected to the detection cavity 123, and one end of the two corresponding clamping blocks 21 in the two movable grooves 111 extends into the detection cavity 123, so that in subsequent tests, the part to be detected 6 is placed in the detection cavity 123, and the part to be detected 6 can be clamped by one end of the two clamping blocks 21 extending into the detection cavity 123, meeting the use requirements of stably clamping the part to be detected 6.

[0033] More specifically, first connecting holes are opened on both sides of the base frame 11, and at the same time, a second connecting hole matching the first connecting hole on the corresponding side of the base frame 11 is opened at the bottom end of each side frame 12. During installation, the first connecting hole and the second connecting hole are connected and locked by threaded fasteners, thereby realizing a detachable connection between the base frame 11 and the two side frames 12. The detachable connection method is a threaded fastener connection, which is more convenient for disassembly and assembly, and provides convenience for the maintenance and inspection of various structures in the subsequent device.

[0034] The coating adhesion detection device provided in this embodiment includes a frame 1, a friction head 3 and a sliding assembly 4; side frames 12 are arranged on both sides of the base frame 11 of the frame 1, and at the same time, a clamping station 2 is arranged on the base frame 11 and between the two side frames 12, and the friction head 3 is arranged between the two side frames 12 and above the clamping station 2, and at the same time, the sliding assembly 4 is installed between the two side frames 12 and the friction head 3, the to-be-detected piece 6 is clamped by the clamping station 2, and the friction head 3 contacts the coating on the to-be-detected piece 6, and the coating is rubbed by the reciprocating movement of the friction head 3, and the wear of the coating and the friction times and pressure of the friction head 3 are observed to determine whether the bonding force of the coating meets the design requirements. The operation is simple and convenient, and the test results are intuitive and reliable, ensuring the test efficiency and result accuracy.
