[0011] Preferably, the alignment mechanism II includes an alignment rotating rod. An installation through slot is penetrated through the mounting chassis.

Alignment torsion springs are fixedly installed on both sides of the alignment rotating ring. The ends of the alignment torsion springs are fixedly connected to the inner wall of the installation through slot. An alignment insertion rod is integrally formed on the alignment rotating ring. Mirror-image distributed alignment grooves are formed in the limiting rotating ring. The alignment insertion rod can be slidably clamped in the alignment grooves.

[0012] Preferably, the detection mechanism I includes an electric steel body fixedly installed on the mounting chassis. The electric steel body has a symmetrical structure. Electric steel sliders are slidably arranged on the electric steel body. The tops of the two electric steel sliders are fixedly installed with a covering frame body. A receiving slot is formed on one side of the covering frame body. The stabilizing stop rod can be slidably clamped in the receiving slot. The covering frame body can be slidably sleeved on the conveying bottom frame. A heating device for cooperation is fixedly installed at the inner bottom end of the covering frame body.

[0013] Preferably, the second detection mechanism includes an arc-shaped rotating cylinder, a cooling fan, and a driving screw sleeve. The arc-shaped rotating cylinder is rotatably installed on the installation base frame, and the arc-shaped rotating cylinder is of a symmetrical structure. The covering frame body is provided with symmetrically arranged accommodating through grooves, and the arc-shaped rotating cylinder is rotatably clamped in the accommodating through grooves. Two installation support plates are fixedly installed on the inner wall of the arc-shaped rotating cylinder, and a connecting rotating shaft and a limiting stop rod are rotatably inserted between adjacent installation support plates. The middle part of the connecting rotating shaft is rotatably sleeved with an installation rotating rod, and the installation rotating rod can contact the limiting stop rod.

[0014] A method for using a motor performance testing device includes the following steps:

[0015] Step 1: Pull the operation grip at the upper end, which can drive the corresponding two fixed collar rings to move, and then drive the corresponding two fixed stop rods to move and stretch the corresponding two fixed springs. Subsequently, clamp any motor to be detected in the corresponding conveying bottom frame and release the corresponding operation grip. At this time, the corresponding two fixed springs will drive the corresponding two fixed collar rings to reset, so as to drive the corresponding two fixed stop rods to reset and conveniently fix the corresponding motor to be detected in the corresponding conveying bottom frame;

[0016] Step 2: Pull the driving push rod to the side away from the installation base frame, which can drive the limit sliding ring and the limit insertion rod to move synchronously and stretch the limit spring. When the end of the limit insertion rod separates from the corresponding limit insertion hole, stop pulling the driving push rod and rotate the conveying rotating rod, which can drive the limit rotating ring and the I-shaped conveying plate to rotate synchronously, and then drive the two conveying bottom frames to rotate, and further drive the motor to be detected to rotate synchronously. When the limit rotating ring rotates 180 degrees, stop rotating the conveying rotating rod and release the driving push rod. At this time, the limit spring will drive the limit sliding ring to reset, so as to drive the limit insertion rod and the stable stop rod to reset, and then enable the limit insertion rod to insert into another corresponding limit insertion hole and make the end of the stable stop rod contact the corresponding motor to be detected;

[0017] Step 3: During this period, when the limit rotating ring rotates, the first alignment mechanism or the second alignment mechanism will operate synchronously, and when the limit rotating ring rotates 180 degrees, the first alignment mechanism or the second alignment mechanism can remind the staff that the motor to be detected just turns to the appropriate position, so as to facilitate the limit insertion rod to quickly and accurately insert into the corresponding limit insertion hole again;

[0018] Step 4: Fix another motor to be inspected according to the above steps. During subsequent operations, the motor to be inspected after detection needs to be removed first, and then a new motor to be inspected is fixed. After that, the two inspection cameras will be started synchronously, so that the motor to be inspected at the lower end can be photographed to inspect its appearance. When the appearance inspection of the corresponding motor to be inspected is completed, the corresponding inspection camera is turned off and the electric steel body is started, so that the covering frame can be driven to move by the electric steel slider until the covering frame is clamped with the conveying bottom frame at the lower end, then the electric steel body is turned off, and then the heating device is started for heating treatment, so that the high-temperature operation stability of the motor to be inspected can be detected. During this period, while the covering frame is moving, it will drive the two driving screw sleeves to move synchronously, so that the corresponding arc-shaped drum can be driven to rotate by the driven lead screw and the inspection camera. When the covering frame stops moving, the arc-shaped drum can block the accommodating through groove on the corresponding side, and under the action of gravity, the inspection camera and the installation rotating rod will rotate automatically, so that the installation rotating rod can be separated from the corresponding limit stop rod and contact with the corresponding heat insulation block. Subsequently, the cooling fan will be started to cool the inspection camera. When the high-temperature operation stability detection operation of the corresponding motor to be inspected is completed, the covering frame is reset. At this time, the arc-shaped drum and the inspection camera will rotate in reverse and reset, so that the installation rotating rod can contact the corresponding limit stop rod again.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. Through the combined use of the conveying mechanism and the limiting mechanism, it provides convenience for the disassembly and assembly of the motor to be inspected, and can quickly and conveniently replace the positions of the two motors to be inspected and stably fix them, thus providing convenience for the operation and use of the user, effectively improving the detection efficiency of the motor to be inspected, and ensuring the stable development of the detection operation of the motor to be inspected.

[0021] 2. Through the setting and use of the alignment mechanism 1 or the alignment mechanism 2, it can perform synchronous operations when the limiting rotating ring rotates and remind the staff that the motor to be inspected just turns to the appropriate position when the limiting rotating ring rotates 180 degrees, so as to facilitate the rapid and accurate insertion of the limiting insertion rod into the corresponding limiting insertion hole again.

[0022] 3. Through the combined use of the detection mechanism 1 and the detection mechanism 2, it can conveniently and quickly perform appearance inspection and high-temperature operation stability inspection on the motor to be inspected, thus effectively improving the practicability of the motor performance testing device. At the same time of switching detection items, the inspection camera can be turned to the side away from the heating device, and the connection area between the inspection camera and the arc-shaped drum can be effectively reduced, thereby effectively reducing the influence of the heat generated by heating on the inspection camera, ensuring the normal use of the inspection camera. In addition, the inspection camera can be cooled by air cooling, further ensuring the normal use of the inspection camera. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1: As Figures 1-7 shown, the present invention provides a motor performance testing device, including an installation chassis 1. A conveying mechanism 2 is provided on one side of the installation chassis 1, and a motor to be inspected 3 is detachably provided on the conveying mechanism 2. A limiting mechanism 4 cooperating with the conveying mechanism 2 is provided at the upper end of one side of the installation chassis 1, and an alignment mechanism I 5 and an alignment mechanism II 6 cooperating with the conveying mechanism 2 are provided on the limiting mechanism 4. A detection mechanism I 7 and a detection mechanism II 8 cooperating with the motor to be inspected 3 are provided on the installation chassis 1. The cooperation between the conveying mechanism 2 and the limiting mechanism 4 facilitates the disassembly, rapid replacement, and stable fixation of the motor to be inspected 3. The setting and use of the alignment mechanism I 5 can remind the staff that the motor to be inspected 3 just rotates to the appropriate position, so as to facilitate rapid and accurate fixation again. The cooperation between the detection mechanism I 7 and the detection mechanism II 8 can conveniently and quickly perform appearance detection and high-temperature operation stability detection on the motor to be inspected 3.

[0036] The conveying mechanism 2 includes a conveying rotating rod 21 which is rotatably inserted into the mounting chassis 1. A T-shaped conveying plate 22 is fixedly sleeved on the conveying rotating rod 21. Both ends of the T-shaped conveying plate 22 are fixedly connected with conveying bottom frames 23. The motor to be inspected 3 can be slidably inserted into the conveying bottom frames 23. A pair of symmetrically arranged fixed stop rods 24 are slidably inserted into one side of the conveying bottom frames 23, and the fixed stop rods 24 can be attached to the outer wall of the motor to be inspected 3. A fixed collar 25 is fixedly sleeved at one end of the fixed stop rod 24. A fixed spring 26 is fixedly installed on one side of the fixed collar 25, and the end of the fixed spring 26 is fixedly connected with the conveying bottom frame 23. An operation grip rod 27 for cooperative use is fixedly installed between the two fixed collars 25. The limiting mechanism 4 includes a limiting sliding ring 41 and a limiting rotating ring 42. The limiting sliding ring 41 is slidably sleeved on the conveying rotating rod 21. A limiting spring 43 is fixedly installed in the middle of one side of the limiting sliding ring 41, and the end of the limiting spring 43 is fixedly connected with the mounting chassis 1. A pair of symmetrically distributed limiting insertion rods 44 are fixedly installed on the side of the limiting sliding ring 41 close to the limiting spring 43. A driving push rod 47 is fixedly installed on the limiting sliding ring 41. The arrangement and use of the driving push rod 47 facilitate the convenient pushing of the limiting sliding ring 41. A layer of anti-slip pattern is covered on the outer wall of the driving push rod 47, and the anti-slip pattern can increase friction and facilitate operation. The limiting insertion rods 44 are slidably inserted into the mounting chassis 1. A stabilizing stop rod 45 is fixedly connected to the limiting sliding ring 41, and the end of the stabilizing stop rod 45 can be attached to the motor to be inspected 3. The limiting rotating ring 42 is fixedly sleeved on the conveying rotating rod 21, and symmetrically arranged limiting insertion holes 46 are formed through the limiting rotating ring 42. The limiting insertion rods 44 can be slidably inserted into the limiting insertion holes 46.

[0037] By adopting the above technical solution, pulling the operation grip rod 27 at the upper end can drive the corresponding two fixed collar rings 25 to move, and then drive the corresponding two fixed stop rods 24 to move and stretch the corresponding two fixed springs 26. Subsequently, any motor 3 to be inspected is clamped in the corresponding conveying bottom frame 23 and the corresponding operation grip rod 27 is released. At this time, the corresponding two fixed springs 26 will drive the corresponding two fixed collar rings 25 to reset, so as to drive the corresponding two fixed stop rods 24 to reset and conveniently fix the corresponding motor 3 to be inspected in the corresponding conveying bottom frame 23. Pull the driving push rod 47 to the side away from the installation base frame 1, so as to drive the limit sliding ring 41 and the limit insertion rod 44 to move synchronously and stretch the limit spring 43. When the end of the limit insertion rod 44 is separated from the corresponding limit insertion hole 46, stop pulling the driving push rod 47 and rotate the conveying rotating rod 21, so as to drive the limit rotating ring 42 and the I-shaped conveying plate 22 to rotate synchronously, and then drive the two conveying bottom frames 23 to rotate, and further drive the motor 3 to be inspected to rotate synchronously. When the limit rotating ring 42 rotates 180 degrees, stop rotating the conveying rotating rod 21 and release the driving push rod 47. At this time, the limit spring 43 will drive the limit sliding ring 41 to reset, so as to drive the limit insertion rod 44 and the stable stop rod 45 to reset, and then enable the limit insertion rod 44 to insert into another corresponding limit insertion hole 46 and make the end of the stable stop rod 45 contact the corresponding motor 3 to be inspected.

[0038] The alignment mechanism I 5 includes a ball head alignment rod 51. Symmetrically distributed sliding through holes 48 are formed through the limit rotating ring 42, and the ball head alignment rod 51 is slidably inserted into the sliding through holes 48. Two alignment concave holes 11 are formed in the installation base frame 1, and the end of the ball head alignment rod 51 can be slidably inserted into the alignment concave holes 11. A alignment collar ring 52 is fixedly sleeved at one end of the ball head alignment rod 51 away from the alignment concave holes 11, and a alignment spring 53 is fixedly installed on one side of the alignment collar ring 52. The end of the alignment spring 53 is fixedly connected to the limit rotating ring 42.

[0039] By adopting the above technical solution, when the limit rotating ring 42 starts to rotate, the end of the ball head alignment rod 51 will be separated from the corresponding alignment concave hole 11 and drive the corresponding alignment collar ring 52 to move to the side away from the limit rotating ring 42, so as to stretch the corresponding alignment spring 53. When the limit rotating ring 42 rotates 180 degrees, the alignment spring 53 will quickly drive the corresponding alignment collar ring 52 and the ball head alignment rod 51 to reset, so as to enable the ball head alignment rod 51 to be clamped into another corresponding alignment concave hole 11 and generate a vibration prompt sound, and then remind the staff that the motor 3 to be inspected just turns to the appropriate position, which is further convenient for the limit insertion rod 44 to quickly and accurately insert into the corresponding limit insertion hole 46 again.

[0040] The first detection mechanism 7 includes a digital piano body 71. The digital piano body 71 is fixedly installed on the installation chassis 1, and the digital piano body 71 has a symmetrical structure. A digital piano slider 72 is slidably arranged on the digital piano body 71, and a covering frame 73 is fixedly installed at the top ends of the two digital piano sliders 72. A receiving slot 75 is opened on one side of the covering frame 73, and the stable stop rod 45 can be slidably clamped in the receiving slot 75. The arrangement of the receiving slot 75 can prevent the covering frame 73 from hitting the stable stop rod 45 when the covering frame 73 moves, thus ensuring the normal movement of the covering frame 73. The covering frame 73 can slide on the conveying bottom frame 23, and a cooperating heating device 74 is fixedly installed at the inner bottom end of the covering frame 73. The second detection mechanism 8 includes an arc-shaped rotating cylinder 81, a cooling fan 82 and a driving sleeve 83. The arc-shaped rotating cylinder 81 is rotatably installed on the installation chassis 1, and the arc-shaped rotating cylinder 81 has a symmetrical structure. Symmetrically arranged receiving through slots 76 are penetrated through the covering frame 73, and the arc-shaped rotating cylinder 81 is rotatably clamped in the receiving through slots 76. Two mounting support plates 84 are fixedly installed on the inner wall of the arc-shaped rotating cylinder 81, and a connecting rotating shaft 85 and a limiting stop rod 86 are rotatably inserted between adjacent mounting support plates 84. An installation rotating rod 87 is rotatably sleeved in the middle of the connecting rotating shaft 85, and the installation rotating rod 87 can contact the limiting stop rod 86. A detection camera 88 cooperating with the motor 3 to be detected is fixedly installed at the end of the installation rotating rod 87. A heat insulation block 810 is fixedly installed on the arc-shaped rotating cylinder 81. The heat insulation block 810 can effectively block the conduction of heat, and the installation rotating rod 87 can contact the heat insulation block 810. The cooling fan 82 is fixedly installed on both sides of the lower end of the installation chassis 1, and the cooling fan 82 cooperates with the detection camera 88. One end of the arc-shaped rotating cylinder 81 is fixedly inserted with a driven lead screw 89. The driving sleeve 83 is fixedly installed on both sides of the covering frame 73, and the driving sleeve 83 is threadedly sleeved on the driven lead screw 89.

[0041] By adopting the above technical solution, the two detection cameras 88 will be started synchronously, so that the motor 3 to be detected located at the lower end can be photographed to detect its appearance. After the appearance detection of the corresponding motor 3 to be detected is completed, the corresponding detection camera 88 will be turned off and the electric steel body 71 will be started. Thus, the covering frame 73 can be driven to move by the electric steel slider 72 until the covering frame 73 is clamped with the conveying bottom frame 23 located at the lower end, then the electric steel body 71 will be turned off, and then the heating device 74 will be started for heating treatment, so that the high-temperature operation stability of the motor 3 to be detected can be detected. During this period, the covering frame 73 will drive the two driving sleeves 83 to move synchronously while moving, so that the corresponding arc-shaped rotating cylinder 81 and the detection camera 88 can be driven to rotate by the driven lead screw 89. When the covering frame 73 stops moving, the arc-shaped rotating cylinder 81 can block the accommodating through groove 76 on the corresponding side, and under the action of gravity, the detection camera 88 and the mounting rotating rod 87 will rotate self, so that the mounting rotating rod 87 can be separated from the corresponding limit stop rod 86 and contact with the corresponding heat insulation block 810. Subsequently, the cooling fan 82 will be started, so that the detection camera 88 can be cooled. When the high-temperature operation stability detection operation of the corresponding motor 3 to be detected is completed, the covering frame 73 will be reset. At this time, the arc-shaped rotating cylinder 81 and the detection camera 88 will rotate in reverse and reset, so that the mounting rotating rod 87 can contact with the corresponding limit stop rod 86 again.

[0042] A method for using a motor performance testing device includes the following steps:

[0043] Step 1: Pull the operation grip 27 at the upper end, so that the corresponding two fixed collar 25 can be driven to move, and then the corresponding two fixed stop bars 24 can be driven to move and stretch the corresponding two fixed springs 26. Subsequently, any motor 3 to be detected is clamped in the corresponding conveying bottom frame 23 and the corresponding operation grip 27 is released. At this time, the corresponding two fixed springs 26 will drive the corresponding two fixed collar 25 to reset, so that the corresponding two fixed stop bars 24 can be driven to reset and the corresponding motor 3 to be detected can be conveniently fixed in the corresponding conveying bottom frame 23;

[0044] Step 2: Pull the driving push rod 47 to the side away from the installation base frame 1, so that the limit sliding ring 41 and the limit insertion rod 44 can be driven to move synchronously and stretch the limit spring 43. And when the end of the limit insertion rod 44 is separated from the corresponding limit insertion hole 46, stop pulling the driving push rod 47 and rotate the conveying rotating rod 21, so that the limit rotating ring 42 and the I-shaped conveying plate 22 can be driven to rotate synchronously, and then the two conveying bottom frames 23 can be driven to rotate, and further the motor 3 to be detected can be driven to rotate synchronously. When the limit rotating ring 42 rotates 180 degrees, stop rotating the conveying rotating rod 21 and release the driving push rod 47. At this time, the limit spring 43 will drive the limit sliding ring 41 to reset, so that the limit insertion rod 44 and the stabilizing stop bar 45 can be driven to reset, and then the limit insertion rod 44 can be inserted into another corresponding limit insertion hole 46 and the end of the stabilizing stop bar 45 can contact with the corresponding motor 3 to be detected;

[0045] Step 3: During this period, when the limit rotating ring 42 starts to rotate, the end of the ball head alignment rod 51 will separate from the corresponding alignment concave hole 11 and drive the corresponding alignment collar 52 to move away from the limit rotating ring 42, thereby stretching the corresponding alignment spring 53. When the limit rotating ring 42 rotates 180 degrees, the alignment spring 53 will quickly drive the corresponding alignment collar 52 and the ball head alignment rod 51 to reset, so that the ball head alignment rod 51 can be snapped into another corresponding alignment concave hole 11 and generate a vibration prompt sound, further reminding the staff that the motor 3 to be inspected just turns to the appropriate position, and further facilitating the rapid and accurate insertion of the limit insertion rod 44 into the corresponding limit insertion hole 46 again;

[0046] Step 4: Fix another motor 3 to be inspected according to the above steps. During later operations, the inspected motor 3 needs to be removed first and then a new motor 3 to be inspected is fixed. After that, the two inspection cameras 88 will be started synchronously, so as to take pictures of the motor 3 to be inspected at the lower end to detect its appearance. When the appearance inspection of the corresponding motor 3 to be inspected is completed, the corresponding inspection camera 88 will be turned off and the electro-steel body 71 will be started, so that the cover frame 73 can be driven to move by the electro-steel slider 72 until the cover frame 73 is clamped with the conveying bottom frame 23 at the lower end, then the electro-steel body 71 will be turned off, and then the heating device 74 will be started for heating treatment, so as to detect the high-temperature operation stability of the motor 3 to be inspected. During this period, when the cover frame 73 moves, it will drive the two driving nuts 83 to move synchronously, so that the corresponding arc-shaped drum 81 and the inspection camera 88 can be driven to rotate by the driven lead screw 89. When the cover frame 73 stops moving, the arc-shaped drum 81 can block the corresponding accommodation through groove 76, and under the action of gravity, the inspection camera 88 and the mounting rotating rod 87 will rotate automatically, so that the mounting rotating rod 87 can separate from the corresponding limit stop rod 86 and contact the corresponding heat insulation block 810. Subsequently, the cooling fan 82 will be started to cool the inspection camera 88.

When the alignment insertion rod 64 is completely separated from the corresponding alignment groove 49, the limit rotating ring 42 is driven to rotate by the conveying rotating rod 21. Then the alignment insertion rod 64 is released. At this time, the alignment torsion springs 63 will make the alignment insertion rod 64 fit against the outer wall of the limit rotating ring 42 through the alignment rotating ring 62. When the limit rotating ring 42 rotates 180 degrees, the alignment torsion springs 63 can push the alignment insertion rod 64 to be clamped into another alignment groove 49, so as to limit the rotation of the limit rotating ring 42, and further remind the staff that the motor 3 to be inspected just turns to the appropriate position, which is further convenient for the limit insertion rod 44 to quickly and accurately insert into the corresponding limit insertion hole 46 again.

[0052] The first detection mechanism 7 includes a digital piano body 71, which is fixedly installed on the installation chassis 1, and the digital piano body 71 is of a symmetrical structure. A digital piano slider 72 is slidably arranged on the digital piano body 71, and a covering frame 73 is fixedly installed at the top ends of the two digital piano sliders 72. A receiving slot 75 is opened on one side of the covering frame 73, and the stable stop rod 45 can be slidably clamped in the receiving slot 75. The setting of the receiving slot 75 can prevent the covering frame 73 from hitting the stable stop rod 45 when the covering frame 73 moves, thus ensuring the normal movement of the covering frame 73. The covering frame 73 can slide on the conveying bottom frame 23, and a cooperating heating device 74 is fixedly installed at the inner bottom end of the covering frame 73. The second detection mechanism 8 includes an arc-shaped rotating cylinder 81, a cooling fan 82 and a driving sleeve 83. The arc-shaped rotating cylinder 81 is rotatably installed on the installation chassis 1, and the arc-shaped rotating cylinder 81 is of a symmetrical structure. Symmetrically arranged receiving through slots 76 are penetrated through the covering frame 73, and the arc-shaped rotating cylinder 81 is rotatably clamped in the receiving through slots 76. Two installation support plates 84 are fixedly installed on the inner wall of the arc-shaped rotating cylinder 81, and a connecting rotating shaft 85 and a limiting stop rod 86 are rotatably inserted between adjacent installation support plates 84. An installation rotating rod 87 is rotatably sleeved in the middle of the connecting rotating shaft 85, and the installation rotating rod 87 can contact the limiting stop rod 86. A detection camera 88 cooperating with the motor 3 to be detected is fixedly installed at the end of the installation rotating rod 87. A heat insulation block 810 is fixedly installed on the arc-shaped rotating cylinder 81, and the heat insulation block 810 can effectively block the conduction of heat, and the installation rotating rod 87 can contact the heat insulation block 810.

[0053] By adopting the above technical solution, the two detection cameras 88 will be started synchronously, so that the motor 3 to be detected located at the lower end can be photographed to detect its appearance. After the appearance detection of the corresponding motor 3 to be detected is completed, the corresponding detection camera 88 will be turned off and the electric steel body 71 will be started. Thus, the covering frame 73 can be driven to move by the electric steel slider 72 until the covering frame 73 is clamped with the conveying bottom frame 23 located at the lower end, then the electric steel body 71 will be turned off, and then the heating device 74 will be started for heating treatment, so that the high-temperature operation stability of the motor 3 to be detected can be detected. During this period, while the covering frame 73 is moving, it will drive the two driving nuts 83 to move synchronously, so that the corresponding arc-shaped drum 81 and the detection camera 88 can be driven to rotate by the driven lead screw 89. When the covering frame 73 stops moving, the arc-shaped drum 81 can block the corresponding accommodation through groove 76, and under the action of gravity, the detection camera 88 and the mounting rotating rod 87 will rotate automatically, so that the mounting rotating rod 87 can be separated from the corresponding limit stop rod 86 and contact with the corresponding heat insulation block 810. Subsequently, the cooling fan 82 will be started to cool the detection camera 88. When the high-temperature operation stability detection operation of the corresponding motor 3 to be detected is completed, the covering frame 73 will be reset. At this time, the arc-shaped drum 81 and the detection camera 88 will rotate in reverse to reset, so that the mounting rotating rod 87 can contact with the corresponding limit stop rod 86 again.

[0054] A method for using a motor performance testing device includes the following steps:

[0055] Step 1: Pull the operation grip 27 at the upper end, so that the corresponding two fixed collar rings 25 can be driven to move, and then the corresponding two fixed stop rods 24 can be driven to move and stretch the corresponding two fixed springs 26. Subsequently, any motor 3 to be detected is clamped in the corresponding conveying bottom frame 23 and the corresponding operation grip 27 is released. At this time, the corresponding two fixed springs 26 will drive the corresponding two fixed collar rings 25 to reset, so that the corresponding two fixed stop rods 24 can be driven to reset and the corresponding motor 3 to be detected can be conveniently fixed in the corresponding conveying bottom frame 23;

[0056] Step 2: Pull the driving push rod 47 to the side away from the mounting base frame 1, so that the limit sliding ring 41 and the limit insertion rod 44 can be driven to move synchronously and stretch the limit spring 43. When the end of the limit insertion rod 44 is separated from the corresponding limit insertion hole 46, stop pulling the driving push rod 47 and rotate the conveying rotating rod 21, so that the limit rotating ring 42 and the I-shaped conveying plate 22 can be driven to rotate synchronously, and then the two conveying bottom frames 23 can be driven to rotate, and further the motor 3 to be detected can be driven to rotate synchronously. When the limit rotating ring 42 rotates 180 degrees, stop rotating the conveying rotating rod 21 and release the driving push rod 47. At this time, the limit spring 43 will drive the limit sliding ring 41 to reset, so that the limit insertion rod 44 and the stabilizing stop rod 45 can be driven to reset, and further the limit insertion rod 44 can be inserted into another corresponding limit insertion hole 46 and the end of the stabilizing stop rod 45 can contact with the corresponding motor 3 to be detected;

[0057] Step 3. During this period, when the limit rotating ring 42 needs to rotate, the alignment inserting rod 64 needs to be rotated first, so as to drive the alignment rotating ring 62 to rotate and twist the alignment torsion spring 63. And when the alignment inserting rod 64 is completely separated from the corresponding alignment groove 49, the limit rotating ring 42 is driven to rotate by the conveying rotating rod 21. Then the alignment inserting rod 64 is released. At this time, the alignment torsion spring 63 will make the alignment inserting rod 64 fit against the outer wall of the limit rotating ring 42 through the alignment rotating ring 62. And when the limit rotating ring 42 rotates 180 degrees, the alignment torsion spring 63 can push the alignment inserting rod 64 into another alignment groove 49, so as to limit the rotation of the limit rotating ring 42, and further remind the staff that the motor 3 to be inspected just turns to the appropriate position, which is further convenient for the limit inserting rod 44 to quickly and accurately insert into the corresponding limit insertion hole 46 again;

[0058] Step 4. Fix another motor 3 to be inspected according to the above steps. And during the later operation, the inspected motor 3 needs to be removed first and then a new motor 3 to be inspected is fixed. Then the two inspection cameras 88 will be started synchronously, so as to take pictures of the motor 3 to be inspected at the lower end to detect its appearance. And when the appearance inspection of the corresponding motor 3 to be inspected is completed, the corresponding inspection camera 88 is turned off and the electric steel body 71 is started, so as to drive the covering frame 73 to move through the electric steel slider 72 until the covering frame 73 is clamped with the conveying bottom frame 23 at the lower end, then the electric steel body 71 is turned off. Then the heating device 74 is started for heating treatment, so as to detect the high-temperature operation stability of the motor 3 to be inspected. During this period, while the covering frame 73 is moving, it will drive the two driving sleeves 83 to move synchronously, so as to drive the corresponding arc-shaped rotating cylinder 81 and the inspection camera 88 to rotate through the driven lead screw 89. And when the covering frame 73 stops moving, the arc-shaped rotating cylinder 81 can block the corresponding accommodating through groove 76. And under the action of gravity, the inspection camera 88 and the mounting rotating rod 87 will rotate self, so that the mounting rotating rod 87 is separated from the corresponding limit stop rod 86 and contacts with the corresponding heat insulation block 810. Then the cooling fan 82 is started, so as to cool the inspection camera 88. When the high-temperature operation stability detection operation of the corresponding motor 3 to be inspected is completed, the covering frame 73 is reset. At this time, the arc-shaped rotating cylinder 81 and the inspection camera 88 will rotate in reverse to reset, so that the mounting rotating rod 87 can contact with the corresponding limit stop rod 86 again.
