[0054] AsFigures 1 to 6 As shown, the embodiment provides a magnetic shoe height detection device, which comprises a jacking assembly 1 and a detection assembly 3. The jacking assembly 1 is provided with a gland assembly 2 above. The jacking assembly 1 is used to jack the shell 200, and the gland assembly 2 is used to limit the upward displacement of the shell 200 along the Z-axis direction. The detection assembly 3 is arranged at the output end of the jacking assembly 1. The detection assembly 3 comprises a test head 31, a first spring 32, a displacement sensor 33, a test seat 34 and a reference block 35. The test seat 34 is arranged at the output end of the jacking assembly 1. The test head 31 is movably inserted into the test seat 34 along the Z-axis direction. The first spring 32 is arranged between the jacking assembly 1 and the test head 31, and is used to support the test head 31. The jacking assembly 1 drives the detection assembly 3 to rise along the Z-axis direction, so that the test head 31 extends into the inside of the shell 200 and abuts against the bottom of the magnetic shoe 100. The displacement sensor 33 is fixedly connected to the test seat 34, and is used to detect the deformation amount of the first spring 32. The reference block 35 is fixedly installed at the top of the test seat 34, and is used to abut against the bottom port edge of the shell 200.

[0055] Specifically, when the shell 200 moves above the detection assembly 3, the jacking assembly 1 drives the detection assembly 3 upward. The detection assembly 3 pushes the shell 200 towards the gland assembly 2 until the shell 200 contacts the gland assembly 2. The gland assembly 2 is used to limit the rising height of the shell 200 along the Z-axis direction. In the process of jacking the shell 200, the test head 31 first abuts against the bottom of the magnetic shoe 100, and the first spring 32 is compressed. Then, the reference block 35 abuts against the bottom port of the shell 200, so that the first spring 32 stops compressing and deforming. The distance error from the bottom of the magnetic shoe 100 to the bottom port of the shell 200 can be fed back through the compression deformation amount of the first spring 32. When the distance from the bottom of the magnetic shoe 100 to the bottom port of the shell 200 is less than the qualified value, the compression deformation amount of the first spring 32 is greater than the preset value. When the distance from the bottom of the magnetic shoe 100 to the bottom port of the shell 200 is the qualified value, the compression deformation amount of the first spring 32 is equal to the preset value. When the distance from the bottom of the magnetic shoe 100 to the bottom port of the shell 200 is greater than the qualified value, the compression deformation amount of the first spring 32 is less than the preset value.

[0056] In the embodiment, the first spring 32 also plays a buffering role, which reduces the influence caused by the rigid contact between the test head 31 and the magnetic shoe 100.

[0057] In the embodiment, the reference block 35 is taken as the reference. After the reference block 35 abuts against the bottom port of the shell 200, the deformation amount of the first spring 32 no longer changes, which ensures that the number detected by the displacement sensor 33 fixedly connected to the test seat 34 is an accurate value.

[0058] In the embodiment, the magnetic tile 100 is in an arc-shaped sheet structure, and the test seat 34 is provided with an arc-shaped slot, and the magnetic tile 100 is movably inserted into the arc-shaped slot of the test seat 34 along the Z-axis direction.

[0059] Optionally, the detection assembly 3 further comprises a connecting plate 36 and a second spring 37, the connecting plate 36 is fixedly installed at one end of the test head 31 inserted into the test seat 34, and the first spring 32 abuts against the bottom of the connecting plate 36; one end of the second spring 37 abuts against the test seat 34, and the other end of the second spring 37 abuts against the connecting plate 36, and the second spring 37 is used for supporting the test seat 34.

[0060] In the rising stage without contacting the shell 200, the test seat 34 and the test head 31 are synchronously raised, the test seat 34 is supported by the first spring 32, the connecting plate 36 and the second spring 37 connected in sequence from bottom to top, and the rigidity impact between the shell 200 and the gland assembly 2 is slowed down.

[0061] Optionally, the magnetic tile height detection device further comprises a rotating assembly 4, the rotating assembly 4 comprises a rotating motor 41, a first transmission wheel 42, a bottom plate 43, a second transmission wheel 44 and a transmission belt, the rotating motor 41 is arranged at the output end of the jacking assembly 1; the first transmission wheel 42 is arranged at the output end of the rotating motor 41; the bottom plate 43 is arranged at the output end of the jacking assembly 1 and rotates around the Z-axis, the bottom end of the first spring 32 abuts against the bottom plate 43, and the test seat 34 is movably arranged on the bottom plate 43 along the Z-axis direction; the second transmission wheel 44 is arranged on the peripheral portion of the test seat 34, and the second transmission wheel 44 is used for driving the test seat 34 to rotate around the Z-axis; and the transmission belt is arranged between the first transmission wheel 42 and the second transmission wheel 44.

[0062] The inner wall of the shell 200 is attached with a plurality of magnetic tiles 100, for example, four, six, eight or even more, and in the embodiment, the inner wall of each shell 200 is attached with four magnetic tiles 100. Two symmetrical test heads 31 are inserted into the test seat 34, and the detection assembly 3 synchronously detects two symmetrical magnetic tiles 100 each time to improve the detection efficiency, and after the first detection is completed, the detection assembly 3 is driven by the rotating motor 41 to rotate 90° around the Z-axis, so as to facilitate the detection of the other two symmetrical magnetic tiles 100.

[0063] Optionally, the rotating assembly 4 further comprises a sleeve 45, the sleeve 45 is fixedly installed on the bottom plate 43, a limiting opening is formed in the middle of the top wall of the sleeve 45, the top of the test seat 34 passes through the limiting opening upwards, and the limiting opening is matched with the top outer wall of the test seat 34 to limit the rotation of the test seat 34 relative to the sleeve 45, and the second transmission wheel 44 is transmissionally arranged on the peripheral portion of the sleeve 45.

[0064] The cooperation between the sleeve 45 and the test seat 34 ensures that the test seat 34 can rotate synchronously with the sleeve 45 around the Z-axis, and also allows the test seat 34 to rise and fall relative to the sleeve 45 along the Z-axis.

[0065] Optionally, the bottom of the test seat 34 is larger than the limiting port, and the top wall of the sleeve 45 can restrict the bottom of the test seat 34 inside the sleeve 45 to prevent the test seat 34 from being pushed away from the sleeve 45 by the first spring 32 and / or the second spring 37.

[0066] Optionally, the detection assembly 3 also includes a guide rod 38, the top end of which is fixedly connected to the test seat 34, and the bottom end of which passes through the base plate 43 and is fixedly connected to the displacement sensor 33.

[0067] The displacement sensor 33 is located below the connecting plate 36. The optimized layout allows for better detection of the compression deformation of the first spring 32. The displacement sensor 33 is fixedly connected to the guide rod 38 to prevent the displacement sensor 33 from shifting relative to the test seat 34 and to avoid detection errors.

[0068] Optionally, the detection assembly 3 also includes a third spring 39, one end of which abuts against the test seat 34 and the other end of which abuts against the base plate 43. The third spring 39 is used to support the test seat 34, further improving the support stability of the test seat 34.

[0069] Optionally, the detection assembly 3 also includes a support plate 310, the bottom end of the guide rod 38 is fixedly connected to the support plate 310, and the displacement sensor 33 is fixedly installed on the support plate 310.

[0070] As an optional technical solution, the lifting assembly 1 includes a lifting cylinder 11, and a pressure sensor 12 is provided at the output end of the lifting cylinder 11. The pressure sensor 12 is used to detect the thrust of the test head 31 on the magnetic tile 100.

[0071] Since the magnetic tile 100 is glued to the inner wall of the outer shell 200, its adhesion ability needs to be tested and analyzed to determine whether it is qualified. The adhesion ability of the magnetic tile 100 to the inner wall of the outer shell 200 is determined by a thrust test. The stronger the adhesion ability of the magnetic tile 100 to the inner wall of the outer shell 200, the greater the thrust that the magnetic tile 100 can withstand. The qualified value of the thrust is set as the first preset value. As long as the thrust of the test head 31 on the magnetic tile 100 reaches the first preset value and the magnetic tile 100 does not loosen, it is determined that the adhesion ability of the magnetic tile 100 to the inner wall of the outer shell 200 meets the standard. When the pressure value fed back by the pressure sensor 12 reaches the first preset value, it is determined that the adhesion ability of the magnetic tile 100 to the inner wall of the outer shell 200 meets the standard, and the detection value fed back by the displacement sensor 33 is accurate by default. When the pressure value fed back by the pressure sensor 12 does not reach the first preset value, it is determined that the adhesion ability of the magnetic tile 100 to the inner wall of the outer shell 200 does not meet the standard. That is, when the magnetic tile 100 is subjected to a thrust less than the first preset value, it will shift relative to the outer shell 200, causing the detection of the third preset value to be interfered with. At this time, the detection value fed back by the displacement sensor 33 is inaccurate by default, so as to avoid defective products leaving the factory.

[0072] Optionally, the lifting assembly 1 also includes a floating joint 13 and a mounting frame structure 14. The floating joint 13 is installed at the output end of the lifting cylinder 11; the mounting frame structure 14 is installed on the floating joint 13, the rotary motor 41 is fixedly installed on the mounting frame structure 14, and the base plate 43 is rotatably mounted on the mounting frame structure 14.

[0073] In this embodiment, the pressure sensor 12 is located at the floating joint 13, and the floating joint 13 is provided between the lifting cylinder 11 and the mounting frame structure 14 to improve the detection accuracy.

[0074] Optionally, the rotating assembly 4 further includes a forward rotation limiting plate 46 and a reverse rotation limiting plate 47. The forward rotation limiting plate 46 is fixedly installed on the periphery of the sleeve 45. The mounting frame structure 14 is provided with a forward limiting member 15, which is used to abut against the forward rotation limiting plate 46 and limit the forward rotation angle of the forward rotation limiting plate 46. The reverse rotation limiting plate 47 is fixedly installed on the periphery of the sleeve 45 and is spaced apart from the forward rotation limiting plate 46. The mounting frame structure 14 is provided with a reverse limiting member 16, which is used to abut against the reverse rotation limiting plate 47 and limit the reverse rotation angle of the reverse rotation limiting plate 47.

[0075] When the rotary motor 41 drives the sleeve 45 to rotate, the forward rotation limiting plate 46 and the forward limiting member 15 cooperate to limit the forward deflection angle of the sleeve 45, and the reverse rotation limiting plate 47 and the reverse limiting member 16 cooperate to limit the reverse deflection angle of the sleeve 45, so as to ensure that the test head 31 can be aligned with the magnetic tile 100.

[0076] Optionally, the capping assembly 2 includes a capping cylinder 21 and a pressing block 23. The output end of the capping cylinder 21 is provided with a wedge 22. The pressing block 23 has a limiting groove 231. The bottom of the limiting groove 231 has an inclined downward fitting groove 232. The capping cylinder 21 drives the wedge 22 to pass through the limiting groove 231 in a horizontal direction. The bottom of the wedge 22 is provided with an inclined fitting part 221, which is used to fit and abut against the inclined wall of the fitting groove 232.

[0077] Different specifications of the outer shell 200 have different axial lengths. For example, when the outer shell 200 is longer, it will contact the pressing block 23 earlier, and the lifting stroke of the lifting cylinder 11 needs to be adjusted. Otherwise, the outer shell 200 may be damaged. However, the lifting stroke of the lifting cylinder 11 is not easy to adjust and the accuracy is not easy to control. Therefore, the adjustment of the lifting stroke of the lifting cylinder 11 should be minimized. For this purpose, in this embodiment, the pressure cap assembly 2 is adjusted first, and the wedge 22 is driven by the pressure cap cylinder 21. The adapter part 221 of the wedge 22 moves away from the adapter groove 232. The distance between the wedge 22 and the adapter groove 232 along the Z-axis is the second preset value. Then, the lifting cylinder 11 lifts the detection assembly 3, and the detection assembly 3 will... The shell 200 is pushed toward the pressing block 23. The inclined wall of the adapter groove 232 of the pressing block 23 contacts the adapter part 221 of the wedge 22, and the pressing block 23 stops rising, thus completing the test. When the length of the shell 200 is short, the capping cylinder 21 drives the wedge 22 in the opposite direction. The adapter part 221 of the wedge 22 approaches the adapter groove 232. The distance between the wedge 22 and the adapter groove 232 along the Z-axis is a third preset value. The third preset value is less than the second preset value. Then, the lifting cylinder 11 lifts the detection component 3. The detection component 3 pushes the shell 200 toward the pressing block 23. The inclined wall of the adapter groove 232 of the pressing block 23 contacts the adapter part 221 of the wedge 22, and the pressing block 23 stops rising, thus completing the test.
