DETAILED DESCRIPTION

[0038] The present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] Example 1

[0040] A comprehensive detection device for annular magnetic blocks, such as Figure 1 As shown, it includes a housing, a deflection structure arranged in the housing in a natural state and coaxially arranged with the annular magnetic block to be tested, a magnetic eccentricity detection component and a magnetic tension detection component, wherein:

[0041] A positioning assembly for positioning the annular magnetic block is disposed on the top of the housing to ensure that the annular magnetic block to be measured maintains a coaxial center with the deflection structure in the initial state, thereby avoiding measurement errors and improving measurement accuracy.

[0042] The deflection structure includes a magnetic ring 3, a deflection frame driven by the magnetic ring 3 to deflect and move upward at the top, and a stabilizing component for stabilizing the bottom of the deflection frame; there is a gap between the magnetic ring 3 and the top opening formed on the top of the shell, and the magnetic ring 3 is attracted by the annular magnetic block to drive the top of the deflection frame to deflect and move upward in the gap; the stabilizing component includes a base 15 fixed to the bottom of the deflection frame, a fixing plate 9 fixed on the bottom of the shell, a group of at least three centripetal springs that balance and pull the base 15 to the periphery of the fixing plate 9, a support shaft 13 fixed to the lower surface of the fixing plate 9, and a support shaft socket 14 formed in the center of the base 15, and the end of the support shaft 13 is in contact with the support shaft socket 14;

[0043] When the deflection structure is in a natural state (a state without an annular magnetic block), the deflection structure and the component to be detected (the annular magnetic block to be detected) are coaxial, and the centripetal spring group provides an upward pulling force to the deflection structure as a whole, and maintains a balance with the overall gravity of the deflection structure. When the deflection structure is under the magnetic force of the annular magnetic block to be detected, the support shaft 13 provides a point-contact lower support for the deflection structure, which can ensure that the deflection structure can use its contact point with the lower support as a fulcrum, and under the magnetic field of the annular magnetic block to be detected with magnetic eccentricity, it presents a radial deflection along the magnetic center direction like an inverted pendulum.

[0044] The magnetic eccentricity detection component is an optical positioning measurement component or a laser positioning measurement component with the annular magnetic block to be detected;

[0045] The magnetic tension detection component is fixed between the support shaft 13 and the fixed plate 9, and includes a force sensor 11 fixed below the fixed plate 9 and a probe seat 12 fixed at the bottom of the force sensor 11, wherein the probe of the force sensor 11 is coaxially arranged with the magnetic ring 3 and the bottom is inserted into the probe seat 12, wherein the support shaft 13 is fixed below the probe seat 12.

[0046] The deflection structure is connected to the fixed plate 9 fixed on the bottom of the housing through a symmetrical spring group. The center of the deflection is connected to a force sensor 11. The support shaft 13 on the probe seat 12 contacts the support shaft socket 14, and the deflection structure can swing around the support point. When the deflection structure is in a natural state, the force sensor 11 returns to zero. After the annular magnetic block to be detected is placed on the positioning assembly for positioning, the annular magnetic block applies an upward magnetic pulling force to the magnetic ring 3, driving the deflection structure to move upward. Under the vertical upward combined pulling action of the symmetrical spring group, the central shaft socket 14 at the lower part of the deflection structure forms an shaft socket with the support shaft 13 on the force sensor 11, and applies axial pressure to the force sensor 11. The force sensor 11 measures the pressure as the magnetic pulling force of the annular magnetic block to be tested. The force sensor 11 is connected to a processor (i.e., an industrial computer) for communication. The processor receives the signal of the force sensor 11 and displays the magnetic pulling force value.

[0047] Specifically, in this embodiment, the magnetic eccentricity detection component uses an optical positioning measurement component. The optical positioning measurement component includes a positioning spot 26 fixed to the lower surface of the top of the yaw frame, and an industrial camera 30 and a light source fixed in the housing by a fixing component, and the light source is located between the industrial camera 30 and the positioning spot 26.

[0048] The magnetic ring 3 is attracted by the annular magnetic block to be measured, driving the top of the deflection frame to deflect in the gap, driving the positioning light spot 26 fixed on the lower surface of the top of the deflection frame to swing, and the positioning light spot 26 is imaged and processed by the CCD industrial camera 30. The industrial camera 30 is communicatively connected with the processor (i.e., the industrial computer). After receiving the measurement and processing signal of the industrial camera 30, the processor can obtain the radial position of the center of the deflection structure relative to the geometric center of the magnetic steel assembly under the action of the permanent magnet magnetic field, and the phase angle corresponding to the position point, thereby easily and quickly obtaining the magnetic eccentricity and magnetic declination of the annular magnetic block to be measured, displaying them on the industrial computer, and automatically storing the measured values.

[0049] Specifically, the fixing assembly includes a camera bracket 31 fixed on the fixing plate 9, a left side plate 27 and a right side plate 29 respectively fixed on both sides of the camera bracket 31, and a clamping ring 28 fixed between the top ends of the left side plate 27 and the right side plate 29, and the light source is fixed in the clamping ring 28.

[0050] The positioning assembly includes a positioning sleeve 1 fixed in the top opening of the shell, two positioning posts 20 fixed above the positioning sleeve 1 and protruding from the top surface of the shell, and an upper positioning surface formed on the top surface of the positioning sleeve 1 and / or the top surface of the shell. The positioning sleeve 1 is arranged in the top opening of the top of the shell, and its outer edge is fixed to the top of the shell by screws 2. When in use, the annular magnetic block to be measured is sleeved on the outer edges of the two positioning posts 20 for axial positioning and placed on the upper positioning surface. The two positioning posts 20 position the inner ring side wall of the annular magnetic block, and the upper positioning surface positions the bottom surface of the annular magnetic block. The two positioning posts 20 and the upper positioning surface cooperate with each other to achieve precise positioning of the annular magnetic block.

[0051] Example 2

[0052] This embodiment introduces the deflection structure in detail based on the embodiment 1.

[0053] The deflection frame includes a circular top support 5 and a bottom support 16 coaxial with the magnetic ring 3, and a hanging basket frame 7 is arranged between the top support 5 and the bottom support 16. The hanging basket frame 7 is three or more evenly distributed support rods, which can minimize the weight of the deflection structure and facilitate the inspection and maintenance of the magnetic tension detection component located inside. The hanging basket frame 7 and the top support 5 are fixed by a set screw 25, the magnetic ring 3 is fixed to the outside of the annular protrusion 5-1 in the middle of the top support 5, and the base 15 is fixed to the upper surface of the bottom support 16 by a fixing nut 17. The hanging basket frame 7 can be deformed so that the top of the deflection structure is offset while the bottom remains stable.

[0054] The fixing plate 9 is a three-pronged plate, which is fixed to the bottom of the housing by three columns 18. The spring group includes three springs 32 of the same material and length. The bottoms of the three springs 32 are fixed to the base 15, and the tops are fixed to the earrings 10 of the three-pronged plate 9. The three springs are symmetrically arranged with the axis of the annular magnet as the axis.

[0055] In order to avoid the influence of the unbalanced mass of the deflection structure itself (mass error that may exist during the processing) on ​​the magnetic eccentricity measurement, the deflection structure is constrained by three evenly distributed centripetal spring groups with consistent stiffness dimensions through structural design, so as to avoid arbitrary rotation of the deflection structure, thereby avoiding the influence of the unbalanced mass of the deflection structure on the magnetic eccentricity measurement. Similarly, with the help of the centripetal spring group on the deflection structure, the impact of the deflection structure on the force sensor and the influence on the measurement are avoided. In addition, with the restraint of the centripetal spring group on the deflection structure, when the measured deflection structure is evacuated after the measurement is completed, it can also maintain balance with the overall gravity of the deflection structure to achieve the acceptance of the deflection structure, thereby ensuring reliable and efficient measurement.

[0056] At the moment of placing the annular magnetic block to be measured, the magnetic ring 3 drives the deflection structure to swing instantaneously. After the deflection occurs, due to the effect of inertia, the unstable deflection structure will shake. In order to ensure the rapid stabilization of the deflection structure during measurement, the fluctuation of the deflection structure during the measurement is alleviated to make the measurement stable. The deflection structure also includes a damping component, which includes a groove formed by the annular protrusion 5-1 for filling the damping oil 34 and a vertical rod 1-1 fixed to the bottom of the positioning sleeve 1 and extending into the groove but not contacting the bottom of the groove. The vertical rod 1-1 forms damping with the damping oil 34, and the vertical rod 1-1 does not contact the bottom of the groove, reserving space for the upward movement of the deflection structure. The damping oil is composed of a special component with a flexible blocking effect, which can reduce the shaking of the deflection structure and promote its stabilization as soon as possible, thereby improving the measurement efficiency.

[0057] The magnetic conductive ring 3 is made of an iron-nickel alloy. Since the iron-nickel alloy is a soft magnetic material, it has a high magnetic permeability and a negligible residual magnetism. Therefore, in the detection device, after completing the measurement of a workpiece and removing the workpiece, the magnetic conductive ring 3 will be in a state of negligible magnetism due to the extremely small residual magnetism, and will not interfere with the measurement of the next annular magnetic block, thereby avoiding the influence of residual magnetism on the magnetic eccentricity measurement when detecting batch annular magnetic blocks.

[0058] Example 3

[0059] This embodiment introduces the shell and support structure in detail on the basis of Embodiment 1 and Embodiment 2.

[0060] The shell includes an upper end cover 4, a lower end cover 19 and a sleeve 6, an arc-shaped gasket 33 is arranged between the lower end cover 19 and the sleeve 6, the upper end cover 4 has an opening at the top, there is a gap between the magnetic ring 3 and the opening formed at the top of the upper end cover 4, and the column 18 is fixed on the lower end cover 19.

[0061] A door 8 is provided on the side wall of the sleeve 6, and opening the door allows for convenient maintenance of internal components.

[0062] The sleeve 6 is made of magnetic shielding material, preferably low carbon steel. Due to the magnetic shielding effect of the outer sleeve made of low magnetic resistance ferromagnetic material, the magnetic lines of force of the interfering magnetic field will be diverted and shunted along the surface of the sleeve, so that the deflection structure in the detection device is in a relatively closed magnetic circuit environment, thereby avoiding the influence of the dynamic interfering magnetic field on the measurement in the production detection site.

[0063] The industrial camera (30) is communicatively connected to the input end of the processor. After receiving the measurement signal of the industrial camera (30), the processor converts and displays the magnetic eccentricity value and the magnetic declination. The output end of the processor is communicatively connected to the annular display panel (21) arranged on the upper end cover (4). The annular display panel 21 is embedded in the upper end cover (4). Its upper surface is flush with the upper surface of the upper end cover (4). A dial seat 22 is arranged below. The dial seat 22 is fixed to the upper end cover 4 by a hexagonal screw 24. LED lights 23 are arranged on the annular display panel 21. The magnetic declination measurement result can be intuitively displayed through the LED lights 23 on the corresponding scale.

[0064] In order to facilitate measurement, the comprehensive detection device also includes a bracket, which includes a stable frame structure composed of a top plate 36, a bottom plate 37 and two side plates 40. A middle partition 38 is arranged between the top plate 36 and the bottom plate 37. An opening of the same shape and size as the top of the annular magnetic block performance detection device is opened in the middle of the top plate 36. The bottom of the annular magnetic block performance detection device is fixed on the middle partition 38, and the top is flush with the top plate 36. The top plate 36 forms a detection platform for convenient and rapid detection.

[0065] As a preferred embodiment, a shock absorber 39 is provided on the bottom support foot of the frame structure to prevent measurement deviation caused by vibration.

[0066] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0067] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0068] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
