DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 7 The automated production line for assembling and testing an elevator control cabinet includes a support frame 1. Both sides of the support frame 1 are provided with movable grooves 2. The interior of the movable grooves 2 are movably sleeved with clamping components 4. The bottom of the clamping component 4 is fixedly connected to a cylinder 3. The interior of the clamping component 4 is clamped with a secondary fixing component 5. The side of the clamping component 4 is fitted with a control cabinet 6.

[0028] When inspecting the control cabinet 6, the control cabinet 6 can be placed at the distance between the clamping components 4 at both ends. At this time, the clamping components 4 are started so that the clamping components 4 at both ends will form a clamping force to fix the control cabinet 6. Then the cylinder 3 is started to push the clamping component 4 to move upward inside the movable groove 2. During the movement, the secondary fixing component 5 will be squeezed. When the secondary fixing component 5 is squeezed, the control cabinet 6 will be fixed for the second time. When the bottom of the control cabinet 6 needs to be inspected, the control cabinet 6 will be turned over. When the top of the control cabinet 6 needs to be inspected, it will be turned over again, thereby improving work efficiency.

[0029] See also Figure 2 The interior of the clamping assembly 4 includes a connecting plate A41, a motor 42, a screw A43, a screw B44, a threaded sleeve 45, a connecting plate B46 and a through-hole 47. The top of the cylinder 3 is fixedly connected to the connecting plate A41, the motor 42 is fixedly installed inside the connecting plate A41, the screw A43 is fixedly installed inside the motor 42, the outer wall of the screw A43 is threadedly sleeved with the screw B44, the outer wall of the screw B44 is threadedly connected to the threaded sleeve 45, and the outer wall of the threaded sleeve 45 is fixedly connected to the inside of the connecting plate A41. The side of the screw B44 away from the screw A43 is movably connected to the connecting plate B46, and a through-hole 47 is formed inside the connecting plate A41.

[0030] By starting the motor 42, the screw A43 fixedly connected to the outer wall of the motor 42 will rotate inside the screw B44, and the screw B44 will be limited by the threaded sleeve 45, so that the screw B44 will move along the outer wall of the screw A43 toward one end of the connecting plate B46. When the screw B44 rotates out inside the threaded sleeve 45, it will rotate inside the connecting plate B46, and at the same time push the connecting plate B46 to extend out from the inside of the connecting plate A41. The connecting plate B46 will also drive the rotating rod 411, the fitting plate 412, and the connecting cap 413 to move forward. When they are in contact with the side of the control cabinet 6, a limit will be formed. In this way, a clamping force can be formed during the work process, which is convenient for lifting the cylinder 3.

[0031] See also Figure 2 The interior of the clamping assembly 4 also includes a slide groove A48, a slide groove B49, a rotating sleeve 410, a rotating rod 411, a fitting plate 412, a connecting cap 413 and a rubber plug 414. The interior of the connecting plate B46 is provided with a slide groove A48, the interior of the slide groove A48 is provided with a slide groove B49, the side of the connecting plate B46 away from the screw B44 is fixedly connected to the rotating sleeve 410, the rotating rod 411 is movably installed inside the rotating sleeve 410, the outer wall of the rotating rod 411 is fixedly installed with the fitting plate 412, the side of the rotating sleeve 410 is movably installed with the connecting cap 413, and the outer wall of the fitting plate 412 is fixedly connected to the rubber plug 414;

[0032] During the forward movement of the connecting plate B46, the secondary fixing component 5 can always remain in place through the cooperation of the slide groove A48 and the through-hole 47, and a slide groove B49 is provided inside the slide groove A48. The slide groove B49 can be used to squeeze the secondary fixing component 5 during the upward movement of the connecting plate B46 pushed by the cylinder 3. When the angle of the control cabinet 6 needs to be adjusted, just pull the connecting cap 413 on the side of the rotating sleeve 410 outward, and the rotating rod 411 can be rotated ninety degrees, so as to facilitate the detection of the top and bottom of the control cabinet 6, thereby ensuring work efficiency and improving usage efficiency.

[0033] See also Figure 3 The interior of the rotating sleeve 410 is fixedly connected to an internal rod 422, and the outer wall of the internal rod 422 is movably connected to the end of the rotating rod 411 away from the laminating plate 412. An arc groove 423 is provided on the outer wall of the end of the rotating rod 411 close to the internal rod 422. A bayonet C424, a bayonet A425, and a bayonet B426 are arranged in an array inside the arc groove 423. The angle between the bayonet A425 and the bayonet C424 is ninety degrees, and the angle between the bayonet A425 and the bayonet B426 is ninety degrees.

[0034] When it is necessary to rotate the rotating rod 411, the connecting cap 413 can be pulled, and the connecting cap 413 will be detached from the inside of the bayonet A425, and the rotating rod 411 can be rotated inside the built-in rod 422. When the connecting cap 413 and the side of the bayonet B426 are in contact, it cannot be rotated. At this time, the angle becomes ninety degrees. The connecting cap 413 can be loosened and pulled, causing the connecting cap 413 to be embedded in the inside of the bayonet B426 to form an angle limit. When it is necessary to detect the top, the connecting cap 413 is clamped to the inside of the bayonet C424 in the same way as above, thereby forming a ninety-degree limit at the reverse angle.

[0035] See also Figure 4 The outer wall of the connecting cap 413 is fixedly connected to the telescopic rod 431, and a spring A432 is wound around the outer wall of the telescopic rod 431. A limit plate 433 is fixedly installed on the end of the telescopic rod 431 away from the connecting cap 413. The outer wall of the limit plate 433 is fixedly connected to a plug pin 444. The outer wall of the telescopic rod 431 is movably connected to the side of the rotating sleeve 410, and the spring A432, the limit plate 433 and the plug pin 444 are all located inside the rotating sleeve 410. The outer wall of the plug pin 444 and the inside of the bayonet C424, the bayonet A425 and the bayonet B426 are adapted to each other.

[0036] When the connecting cap 413 is pulled again, the telescopic rod 431 fixedly connected at the bottom will extend from the inside of the rotating sleeve 410. When extending, the limit plate 433 and the spring A432 are retained in the rotating sleeve 410, causing the limit plate 433 to squeeze the spring A432 wrapped around the outer wall of the telescopic rod 431, and the plug pin 444 fixedly connected to the bottom of the limit plate 433 and the above-mentioned bayonet C424, bayonet A425, and bayonet B426 are embedded and installed to form a limit. When the plug pin 444 is pulled out of the inside of the bayonet A425, it is always located in the inside of the arc groove 423, so that the plug pin 444 can fit with the side of the arc groove 423 during the rotation process, and then a preliminary limit can be formed. When the control cabinet 6 needs to be vertical, the connecting cap 413 can be pulled out of the bayonet C424 or the bayonet B426 in advance. At this time, the limiting force is cancelled and the control cabinet 6 can be flipped over. When flipping, the connecting cap 413 is released so that the bottom connecting pin 444 can fit into the bottom of the arc groove 423. During the flipping process, the connecting pin 444 will move along the bottom of the arc groove 423 to the inside of the bayonet A425 to form a snap connection. At this time, no shaking will be caused, thereby improving work efficiency.

[0037] See also Figure 1 The interior of the secondary fixing component 5 includes an air cylinder 51, a push rod 52, an air hose 53, a bottom tube 54 and a clamp 55. The push rod 52 is clamped inside the slide groove B49, and the top of the push rod 52 is movably connected to the air cylinder 51. The top of the air cylinder 51 is fixedly connected to the top of the support frame 1, and the side of the air cylinder 51 is fixedly connected to the air hose 53. The air hose 53 passes through the inside of the through-port 47 and is fixedly connected to the inside of the bottom tube 54, and the top of the bottom tube 54 is fixedly connected to the bottom of the connecting plate A41. The clamp 55 is movably installed on one side of the bottom of the bottom tube 54. An air storage chamber A59 is opened inside the air storage chamber A59, and an extrusion plug 58 is movably connected inside the air storage chamber A59. The bottom of the extrusion plug 58 is fixedly connected to the push rod 52, and a slide 57 is fixedly installed on the bottom of the push rod 52. The two sides of the slide 57 are clamped with the inside of the slide groove B49.

[0038] When the cylinder 3 pushes the clamping assembly 4 to move upward, the internally movable connecting plate B46 will also move upward. When the connecting plate B46 moves upward, the internally engaged slide 57 will drive the push rod 52 to move toward the inside of the air cylinder 51. During the movement, the extrusion plug 58 fixedly connected to the top of the push rod 52 will squeeze the air stored in the air storage chamber A59, so that the air will be transported from the air supply hose 53 to the inside of the bottom tube 54. At this time, the clamp 55 will extend out from the inside of the bottom tube 54, forming a secondary fixation on the side of the control cabinet 6. It should be noted that the slide 57 fixedly connected to the bottom of the push rod 52 is movably connected to the slide B49 opened inside the slide A48. When the connecting plate B46 moves forward, the slide 57 can be kept at a distance and will not be pushed by the connecting plate B46, so that it is convenient to squeeze the air inside the air cylinder 51 later, thereby improving work efficiency.

[0039] See also Figure 6 An air storage chamber B591 is provided at the bottom of the bottom tube 54. The interior of the air storage chamber B591 is movably connected to the moving plug 510. An extension rod 511 is fixedly connected to the side of the moving plug 510. A side of the extension rod 511 away from the moving plug 510 is fixedly connected to a rotating shaft 512. A side of the rotating shaft 512 away from the extension rod 511 is fixedly connected to the side of the chuck 55. A fitting block 513 is movably installed inside the chuck 55. A support plate 514 is provided at the bottom of the fitting block 513. The outer wall of the support plate 514 is movably connected to the bottom of the chuck 55.

[0040] When the gas enters the bottom tube 54, it will be stored inside the gas storage chamber B591. At this time, the movable plug 510 will be pushed by the gas to extend the extension rod 511 out from the inside of the gas storage chamber B591, so that the clamp 55 that is movably connected to the side of the rotating shaft 512 can form a secondary fixation with the side of the control cabinet 6. It should be noted that when the control cabinet 6 rotates, the clamp 55 that is movably connected to the side can also follow the clamping assembly 4 through the rotating shaft 512 to rotate 90 degrees, thereby enhancing the fixation and improving the use efficiency.

[0041] See also Figure 6 The chuck 55 has an inner cavity A515 formed inside, a cross bar 516 is fixedly installed inside the inner cavity A515, a spring B517 is wound around the outer wall of the cross bar 516, an extension plug B518 is fitted and connected to the side of the spring B517, a side of the extension plug B518 away from the spring B517 is fixedly connected to the outer wall of the fitting block 513, and the interiors of the fitting block 513 and the extension plug B518 are movably connected to the outer wall of the cross bar 516, the bottom of the inner cavity A515 is connected to the inner cavity B521, an extension plug A520 is movably connected to the interior of the inner cavity B521, the outer wall of the extension plug A520 is fixedly connected to the bottom rod 519, and the side of the bottom rod 519 is fixedly connected to the outer wall of the support plate 514;

[0042] When the sides of the chuck 55 and the control cabinet 6 fit together, the fitting block 513 will be squeezed, which will cause the fitting block 513 to shrink toward the inside of the chuck 55. During the shrinkage process, the extension plug B518 fixedly connected to the outer wall of the fitting block 513 will squeeze the spring B517 along the cross bar 516. At the same time, the extension plug B518 will discharge the air stored in the inner cavity A515 into the inner cavity B521 in the process of squeezing the spring B517. In the process of entering the inner cavity B521, the extension plug A520 will be pushed to extend out from the inner cavity B521. During the extension process, the support plate 514 fixedly connected to the side of the bottom rod 519 will move to the bottom of the control cabinet 6 to form a support for the bottom of the control cabinet 6, thereby preventing it from detaching from the inside of the clamping assembly 4 due to excessive gravity when vertical, thereby enhancing practicality.

[0043] See also Figure 2 , the interior of the chute A48 and the interior of the through-port 47 are vertically parallel, and the bottom of the gas hose 53 passes through the chute A48;

[0044] The slide groove A48 and the through-hole 47 are arranged to be vertically parallel to each other, so that the gas hose 53 can be easily inserted inside and the connecting plate B46 can be prevented from being pulled by the gas hose 53 during the forward movement, thereby improving work efficiency.

[0045] Working principle: During use, when inspecting the control cabinet 6, the control cabinet 6 can be placed at the distance between the clamping components 4 at both ends. At this time, the clamping components 4 are started, so that the clamping components 4 at both ends will form a clamping force to fix the control cabinet 6. Then, the cylinder 3 is started to allow the cylinder 3 to push the clamping component 4 to move upward inside the movable groove 2. During the movement, the secondary fixing component 5 will be squeezed. When the secondary fixing component 5 is squeezed, the control cabinet 6 will be fixed for the second time. When the bottom of the control cabinet 6 needs to be inspected, the control cabinet 6 will be flipped over, and when the top of the control cabinet 6 needs to be inspected, it will be flipped over again, thereby enhancing work efficiency.
