[0002] A fire extinguisher is a portable fire-fighting tool. Chemicals are placed inside the fire extinguisher to put out fires. Fire extinguishers are one of the common fire prevention facilities and are stored in public places or places where fires may occur. Different types of fire extinguishers are filled with different ingredients and are designed for different causes of fire. When a fire extinguisher is produced, a valve needs to be assembled on the fire extinguisher;

[0018] S2: Rotate and place;

[0019] S3: Rotational assembly.

[0020] The present invention has the following beneficial effects:

[0021] 1. In the present invention, when the rotating clamp puts the valve body into the placement hole on the right side, the edge of the valve body will be at the top of the rotating ring, and then when the rotating clamp presses the valve body downward, the valve body will squeeze the elastic frame through the rotating ring, and the elastic frame will drive the fixed ring to move downward and squeeze the multiple telescopic spring columns when squeezing downward, and then when the fixed ring moves to the bottom, the elastic frame that continues to move downward will contact the inner wall of the placement hole under the downward pressure from the top, and then when the elastic frame continues to move downward, the elastic frame will bulge outward from bottom to top, and when the elastic frame is deformed, the bulged part will contact the inclined surface of the right-angle bar, and then with the elastic As the elastic skeleton continues to deform, the elastic skeleton will generate an upward extrusion force on the inclined surface of the right-angled bar during deformation. At this time, the right-angled bar will move upward inside the T-slot under the push of the extrusion force. When the T-slot moves upward, it will push the inclined plate to rotate through the middle rod. When the inclined plate rotates, it will push the top surface of the elastic skeleton relatively. When the top of the elastic skeleton is pushed by the inclined plate, it will drive the two semicircular plates to move relatively. When the semicircular plates move relatively, they will cover the surface of the valve body and keep it in the middle of the slot, thereby realizing precise positioning of the valve body, reducing the impact on the assembly accuracy between the valve body and the valve stem nut when the valve body is rotated for assembly, and reducing the occurrence of deviations.

[0022] 2. In the present invention, when the top of the elastic skeleton moves downward after being squeezed, the downward movement of the elastic skeleton will drive multiple auxiliary plates to move downward synchronously, and then when the elastic skeleton moves downward, the auxiliary plates on the elastic skeleton will squeeze the bottom of the arc plate, and when the bottom of the arc plate is pushed by the auxiliary plates, it will drive the rubber ring to stretch to both sides, and then when the valve body moves downward, the stretched rubber ring can form a flexible layer at the bottom of the nut, and then when the valve body is rotated and assembled, the rotation of the nut can be reduced, so that the relative position between the nut and the valve body remains stable, which can ensure the accuracy of assembly between the valve body and the nut and improve the assembly accuracy.

[0023] 3. In the present invention, when the elastic skeleton pushes the fixing ring to move downward, the multiple insertion rods on the fixing ring will slide inside the arc groove, and then when the fixing ring slides down, the insertion rods will guide the fixing ring to rotate along the trajectory of the arc groove, and when the fixing ring rotates, it will drive the gear ring to rotate synchronously through the multiple telescopic spring columns, and when the gear ring rotates, it will drive the multiple gear shafts to rotate, and when the gear shaft rotates, it will drive the spherical rod and the hollow column between the multiple spherical rods to rotate and slide upward through the obtuse plate, because when the nut is placed inside the placement hole, the hollow column is in the nut. When the hollow column slides upward, the piston rod on the hollow column will contact the valve body. Then, when the hollow column continues to move upward, the upward movement of the hollow column will push the push plate to expand upward through the rotating plate at the bottom. When the push plate expands, it will support the inner wall of the nut, which can further reduce the synchronous rotation of the nut caused by the valve body during rotation assembly, further enhance the stability of the nut assembly, and reduce the assembly deviation or slippage caused by the rotation of the nut and the valve body during the assembly process, thereby further improving the assembly accuracy.

[0024] 4. In the present invention, when the top of the piston rod contacts the valve body, the piston rod will slide downward inside the hollow column as the hollow column continues to move upward. When the piston rod slides downward inside the hollow column, the gas inside the piston rod will be squeezed. When the gas inside the hollow column is squeezed, it will enter the push plate and the airbag layer through the opening at the bottom of the piston rod and the connecting tube. Then, the airbag layer will expand under the entry of gas and form a flexible buffer layer between the push plate and the inner wall of the nut, which can avoid hard contact between the push plate and the inner wall of the nut during expansion, reduce the local excessive pressure on the inner wall of the nut during expansion of the push plate, reduce the risk of damage to the inner wall of the nut due to local uneven force, and reduce the deformation of the inside of the nut during expansion of the push plate, so as to maintain the assembly quality of the components during assembly.

[0049] A method for using a fire extinguisher valve automatic assembly device, the fire extinguisher valve automatic assembly device, the method comprising the following steps:

[0050] S1: parts conveying;

[0051] S2: Rotate and place;

[0052] S3: Rotational assembly.

[0053] When in use, first the valve body, valve core, nut and other parts that need to be assembled are transported to the feed rack 104 in sequence through the external conveying device, and then the motor 102 is started. When working, the motor 102 will drive the rotating disk 110 to rotate slightly and stop, and then the electric push rods 106 on the multiple support plates 105 in sequence, the electric push rods 106 will put the parts that need to be assembled except the valve body into the placement hole 202 on the right side in sequence when working, and then when rotating, the support plate 105 will control the electric clamp 108 to put the valve body into the placement hole 202 on the left side, and then when the rotating disk 110 drives the accessories that need to be assembled to rotate to the bottom of the rotating clamp 109, the electric push rod 106 on the last support plate 105 will control the rotating clamp 109 to clamp the valve body to the placement hole 202 on the right side, and then the rotating clamp 109 will press the valve body downward and rotate it to assemble it with the nut to complete the assembly purpose.

[0054] When the rotating clamp 109 puts the valve body into the placement hole 202 on the right, the edge of the valve body will be at the top of the rotating ring 303, and then when the rotating clamp 109 presses the valve body downward, the valve body will squeeze the elastic skeleton 301 through the rotating ring 303, and when the elastic skeleton 301 is squeezed downward, it will drive the fixing ring 304 to move downward and squeeze the multiple telescopic spring columns 601. Then, when the fixing ring 304 moves down to the bottom, the elastic skeleton 301 that continues to move downward will contact the inner wall of the placement hole 202 under the downward pressure from the top, and then when the elastic skeleton 301 continues to move downward, the elastic skeleton 301 will produce an outward bulging deformation from bottom to top, and when the elastic skeleton 301 is deformed, the bulging part will contact the inclined surface of the right-angle bar 401, and then as As the elastic skeleton 301 continues to deform, the elastic skeleton 301 will generate an upward extrusion force on the inclined surface of the right-angled bar 401 during deformation. At this time, the right-angled bar 401 will move upward inside the T-slot 204 under the push of the extrusion force. When the T-slot 204 moves upward, it will push the inclined plate 403 to rotate through the middle rod 402. When the inclined plate 403 rotates, it will push the top surface of the elastic skeleton 301 relatively. When the top of the elastic skeleton 301 is pushed by the inclined plate 403, it will drive the two semicircular plates 302 to move relatively.

[0055] When the top of the elastic skeleton 301 moves downward after being squeezed, the downward movement of the elastic skeleton 301 will drive multiple auxiliary plates 501 to move downward synchronously, and then when the elastic skeleton 301 moves downward, the auxiliary plates 501 on the elastic skeleton 301 will squeeze the bottom of the arc plate 502, and when the bottom of the arc plate 502 is pushed by the auxiliary plates 501, it will drive the rubber ring 503 to stretch to both sides, and then when the valve body moves downward, the stretched rubber ring 503 can form a flexible layer at the bottom of the nut, and then when the valve body is rotated and assembled, the rotation of the nut can be reduced, so that the relative position between the nut and the valve body remains stable, which can ensure the accuracy of the assembly between the valve body and the nut and improve the assembly accuracy.

[0056] When the elastic skeleton 301 pushes the fixing ring 304 to move downward, the multiple insertion rods on the fixing ring 304 will slide inside the arc groove 203, and then when the fixing ring 304 slides down, the insertion rods will guide the fixing ring 304 along the trajectory of the arc groove 203 to rotate. When the fixing ring 304 rotates, it will drive the gear ring 602 to rotate synchronously through the multiple telescopic spring columns 601, and the gear ring 602 will drive the multiple gear shafts 603 to rotate when rotating. When the gear shaft 603 rotates, it will drive the spherical rod and the hollow column 605 between the multiple spherical rods to rotate and slide upward at the same time through the obtuse plate 604. Since the hollow column 605 is 605 is located inside the nut. When the hollow column 605 slides upward, the piston rod 606 on the hollow column 605 will contact the valve body. Then, when the hollow column 605 continues to move upward, the upward movement of the hollow column 605 will push the push plate 702 to expand upward through the rotating plate 701 at the bottom. When the push plate 702 expands, it will support the inner wall of the nut, which can further reduce the situation where the valve body drives the nut to rotate synchronously during the rotation assembly, further enhance the stability of the nut assembly, and can also reduce the assembly deviation or slippage caused by the rotation of the nut and the valve body during the assembly process, further improve the assembly accuracy, and can also improve the assembly accuracy.

[0057] When the top of the piston rod 606 contacts the valve body, the piston rod 606 will slide downward inside the hollow column 605 as the hollow column 605 continues to move upward. When the piston rod 606 slides downward inside the hollow column 605, the gas inside the piston rod 606 will be squeezed. When the gas inside the hollow column 605 is squeezed, it will enter the push plate 702 and the airbag layer 703 through the opening at the bottom of the piston rod 606 and the connecting tube 704. Then, the airbag layer 703 will expand under the entry of gas and form a flexible buffer layer between the push plate 702 and the inner wall of the nut, which can avoid hard contact between the push plate 702 and the inner wall of the nut during expansion, reduce the situation where the push plate 702 causes excessive local pressure on the inner wall of the nut when the push plate 702 expands, and reduce the risk of damage to the inner wall of the nut due to local uneven force. At the same time, it can also reduce the deformation of the inside of the nut when the push plate 702 expands, and maintain the assembly quality of the components during assembly.
