Description

Technical Field

[0001] The invention relates to the technical field of fire extinguishing agent bottle welding, in particular to a welding device for a heptafluoropropane gas fire extinguishing agent storage bottle. Background Art

[0002] Heptafluoropropane is a clean gas chemical fire extinguishing agent that mainly uses chemical fire extinguishing and also has physical fire extinguishing effects. Heptafluoropropane is generally stored in a storage bottle. The storage bottle is welded from the bottle mouth, the upper bottle body and the lower bottle body. In the manufacturing process of the storage bottle, welding is a very critical link. The quality of welding will directly affect the sealing of the storage bottle and the safety of use under high pressure.

[0003] In the conventional welding, the bottle mouth, the upper bottle body and the lower bottle body are first butted together, and then the bottle mouth, the upper bottle body and the lower bottle body are placed between the left and right clamps for clamping. After that, the left and right clamps drive the bottle mouth, the upper bottle body and the lower bottle body to rotate circumferentially, and the weld between the three is welded by a welding gun.

[0004] However, the above welding process still has the following shortcomings: 1. Since the left and right clamps only clamp and fix the bottle mouth and the lower bottle body, the upper bottle body is fixed by the inward clamping force of the bottle mouth and the lower bottle body. Therefore, during the welding process, the upper bottle body is prone to misalignment, resulting in misalignment of the welding parts, affecting the quality of welding; 2. During the welding process, the upper bottle body and the welding part are in a suspended state, lacking effective support, affecting the stability of welding; 3. The bottle mouth, the upper bottle body and the lower bottle body are only fixed as a whole by the clamping force at both ends. During the inward squeezing process of the clamping force at both ends, it is easy to cause the welding part to be squeezed and deformed. At the same time, the docking stability between the bottle mouth, the upper bottle body and the lower bottle body is not ideal during the subsequent rotation and welding. Summary of the invention

[0035] See also Figure 1 and Figure 4 The top of the guide seat 1 is provided with an arc groove 11 and an arc groove 2 12 from right to left in sequence. The arc groove 11 and the arc groove 2 12 are connected to each other and their axes coincide with each other.

[0037] See also Figure 1 , Figure 3 , Figure 4 and Figure 6 The clamping mechanism 4 includes a left clamping plate 41 and a right clamping plate 42 which are distributed from left to right along the axial direction of the arc groove 12 and are respectively located on the left and right sides of the arc groove 12.

[0038] See also Figure 3 , Figure 7 and Figure 8 The inner support mechanism 7 includes a center rod 71 fixedly installed on the right side of the left clamping plate 41, and a plurality of inner support rods 72 are evenly distributed on the outer circumference of the center rod 71. A support assembly 73 for pushing the inner support rods 72 to expand and move outward is installed on the center rod 71. An inner support plate 74 and an adjustment assembly 75 for adjusting the inner support plate 74 left and right are installed on the right end of the center rod 71.

[0039] See also Figure 1 , Figure 2 , Figure 4 and Fig. 9 The right end of the arc groove 11 passes through the right side of the guide seat 1, and the left end of the arc groove 2 12 passes through the left side of the guide seat 1. The arc groove 11 and the arc groove 2 12 are respectively adapted to the bottle body and the bottle mouth of the storage bottle. A support plate 13 is fixedly connected to the rear side of the guide seat 1, and two support frames 14 for clamping and fixing two welding gun heads are fixedly installed on the top of the support plate 13.

[0040] Before welding the storage bottle, place the bottle mouth in the arc groove 2 12, and then place the upper bottle body and the lower bottle body in the arc groove 1 1 in sequence from left to right. The arc groove 1 1 is used to support the upper bottle body and the lower bottle body, and the arc groove 2 12 is used to support the bottle mouth, so that the axes of the three can be overlapped, so that the welding surfaces of the three can be aligned, avoiding the misalignment of the welding surfaces during subsequent clamping.

[0041] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 The bottom of the horizontal section and the vertical section of the L-shaped pressing block 21 are respectively provided with a groove 1 and a groove 2 adapted to the bottle body and the bottle mouth of the storage bottle, the groove 1 and the groove 2 are respectively located directly above the arc groove 1 11 and the arc groove 2 12, and the vertical section of the L-shaped pressing block 21 is pressed against the top of the guide seat 1, and the inner surfaces of the arc groove 1 11, the arc groove 2 12, the groove 1 and the groove 2 are all provided with balls.

[0042] Before the bottle mouth, upper bottle body and lower bottle body are clamped left and right, the L-shaped clamping block 21 first presses the bottle mouth, upper bottle body and lower bottle body from above to improve the stability of the bottle mouth, upper bottle body and lower bottle body, and avoid the upper and lower movable misalignment when the bottle mouth, upper bottle body and lower bottle body are clamped left and right later, ensuring that the welding surfaces of the three are aligned, and by arranging balls on the arc groove 1 11, the arc groove 2 12, the groove 1 and the groove 2, it is beneficial for the bottle mouth, the upper bottle body and the lower bottle body to move smoothly left and right when clamped and rotate smoothly during welding.

[0043] See also Figure 2 , Figure 3 and Figure 5 The elastic downward pressing component 22 includes a connecting rod 221 located above the L-shaped pressing block 21, and the front end of the connecting rod 221 is fixedly connected to a horizontal plate 222. The left and right ends of the horizontal plate 222 are both slidably installed with guide rods 223. The bottom of the guide rod 223 is fixedly connected to the top of the L-shaped pressing block 21, and a first compression spring 224 is fixedly connected between the L-shaped pressing block 21 and the horizontal plate 222 and is sleeved on the outside of the guide rod 223.

[0044] By providing an elastic pressing assembly 22 on the L-shaped pressing block 21, when the driving mechanism 5 drives the connecting rod 221 to move downward so that the L-shaped pressing block 21 is pressed against the storage bottle, the driving mechanism 5 can continue to drive the connecting rod 221 to move downward, so that the first compression spring 224 is compressed, thereby providing sufficient displacement for the subsequent left clamping plate 41 and the right clamping plate 42 to clamp on the left and right ends of the storage bottle.

[0045] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The limiting mechanism 3 includes two groups of card joints 31 which are slidably installed inside the guide seat 1 and are symmetrically distributed front and back about the arc groove 11. The number of card joints 31 in each group is two. The top of the card joint 31 is wedge-shaped, and the bottom of the card joint 31 is fixedly connected with a connecting plate 32. A return spring 33 is fixedly connected between the right side of the connecting plate 32 and the inner wall of the guide seat 1. A push rod 34 is fixedly connected to the left side of the connecting plate 32. The left end of the push rod 34 slides through the outside of the guide seat 1. A plurality of arc plates 35 corresponding to the card joints 31 are fixedly installed on the L-shaped clamping block 21. A card interface 36 is provided at the bottom of the arc plate 35, and the card joint 31 cooperates with the card interface 36.

[0046] When the L-shaped clamping block 21 is pressed downward on the storage bottle, the arc plate 35 gradually approaches the top of the guide seat 1. At this time, the card interface 36 contacts the top inclined surface of the card joint 31 and pushes the card joint 31 to move to the right. When the bottom of the arc plate 35 contacts the top of the guide seat 1, the rebound force of the return spring 33 is used to push the connecting plate 32 to move to the left, so that the top of the card joint 31 is clamped on the upper end of the card interface 36, thereby connecting the L-shaped clamping block 21 and the guide seat 1 together. The arc plate 35 cannot move up and down, thereby improving the firmness of the L-shaped clamping block 21 to press the storage bottle.

[0047] See also Figure 1 , Figure 2 , Figure 3 and Figure 6 The driving mechanism 5 includes a shell 51 fixedly mounted on the top of the support plate 13, a two-way telescopic assembly 52 for driving the left clamping plate 41 and the right clamping plate 42 to move toward each other is mounted on the shell 51, and an up-and-down moving assembly 53 for driving the connecting rod 221 to move up and down is also mounted on the shell 51, and a driving motor 54 for driving the two-way telescopic assembly 52 and the up-and-down moving assembly 53 is fixedly mounted on the rear side of the shell 51.

[0049] When the left clamping plate 41 and the right clamping plate 42 are driven to clamp the storage bottle to the left and right, the bidirectional lead screw 522 is driven to rotate by the driving motor 1 54, and then the bidirectional lead screw 522 drives the movable block 523 and the clamping wall 524 to move toward the center of the shell 51, and then the clamping wall 524 drives the left clamping plate 41 and the right clamping plate 42 to move toward each other, and the right clamping plate 42 will first contact with the lower bottle body and push the lower bottle body to move to the left, so that the lower bottle body and the upper bottle body are in contact with each other, and then the right clamping plate 42 continues to push the lower bottle body When the upper bottle body is close to the bottle mouth, the left clamping plate 41 moves to the left side of the bottle mouth and pushes the bottle mouth to move to the right, so that the bottle mouth and the upper bottle body are in contact with each other. At this time, the left clamping plate 41 is still located on the left side of the guide seat 1 and the bottle mouth is still in the arc groove 12; after the storage bottle is clamped left and right, the rotating shaft 525 and the right clamping plate 42 are driven to rotate by the rotating motor 6, and then the right clamping plate 42 drives the clamped storage bottle and the left clamping plate 41 to rotate, so as to facilitate the subsequent welding of the weld by the welding gun.

[0050] See also Figure 1 , Figure 2 , Figure 3 and Figure 6 The up and down moving component 53 includes a gear 531 fixedly installed in the middle of the bidirectional screw 522, and a rack 532 is slidably installed on the shell 51.

[0051] When the driving motor 54 drives the bidirectional lead screw 522 to rotate, the bidirectional lead screw 522 will drive the gear 531 to rotate together, and then the gear 531 drives the rack 532 to move downward, and then the rack 532 drives the connecting rod 221 to move downward, so that the L-shaped clamping block 21 can clamp the storage bottle before the left clamping plate 41 and the right clamping plate 42 clamp the storage bottle, ensuring that the bottle mouth, the upper bottle body and the lower bottle body are on the same axis.

[0055] By arranging an inner support plate 74 at the right end of the center rod 71, when the left clamping plate 41 and the right clamping plate 42 clamp the storage bottle to the left and right, the inner support plate 74 can abut against the inner wall of the lower bottle body, and can limit the clamping degree between the left clamping plate 41 and the right clamping plate 42, so as to prevent the storage bottle from being deformed due to excessive clamping degree of the left clamping plate 41 and the right clamping plate 42, thereby affecting the alignment of the weld. Specifically, by pushing the movable sheet 752 to move to the right to separate the limit block 755 from the limit groove 754, and then rotating the inner support plate 74 and the threaded The rod 751 can adjust the distance between the inner support plate 74 and the center rod 71, so that the inner support plate 74 can support and limit the storage bottles with different internal lengths. Then, the movable plate 752 is loosened, and the rebound force of the reset spring 753 is used to push the movable plate 752 to move to the left, so that the limit block 755 can be inserted into the corresponding limit groove 754, so that the threaded rod 751 cannot rotate relative to the center rod 71, thereby limiting the distance of the inner support plate 74 and preventing the inner support plate 74 from moving during the rotation and welding of the storage bottle.

[0056] See also Figure 2 , Fig. 9 and Fig.10 The rolling mechanism 8 includes a guide rod 81 which is slidably installed in the right support frame 14 along the length direction of the welding gun and is symmetrically distributed about the welding gun. The end of the guide rod 81 away from the support frame 14 is fixedly connected with an arc frame 82, and a second compression spring 83 arranged on the outside of the guide rod 81 is fixedly connected between the arc frame 82 and the support frame 14. An axle rod 84 is fixedly connected between the upper and lower ends of the left and right arc frames 82, and rollers 85 symmetrically distributed on the left and right are rotatably installed on the axle rod 84. A pull rope 86 is fixedly connected to the right end of the right arc frame 82, and the pull rope 86 is fixedly connected to the connecting rod 221 after sliding through the support frame 14 at one end away from the arc frame 82.

[0057] When the welding gun is welding the weld between the upper bottle body and the lower bottle body, the roller 85 can roll and press on the bottle body on the left and right sides of the weld, and cooperate with the internal support of the inner support rod 72 for the upper and lower bottle bodies, so that the roller 85 can level and align the bottle bodies on the left and right sides of the weld, thereby improving the welding effect. When the L-shaped clamping block 21 moves upward to release the clamping of the storage bottle, the connecting rod 221 can pull the pull rope 86 to move upward, and then the pull rope 86 pulls the arc frame 82 to move upward, so that the roller 85 is away from the storage bottle and compresses the second compression spring 83, which is convenient for the subsequent loading and unloading of the storage bottle.

[0058] See also Figure 1-Figure 10 When in use, step 1, in the initial state, the L-shaped pressing block 21 is located above the guide seat 1 and does not contact the guide seat 1, and the left clamping plate 41 and the right clamping plate 42 are located on the left and right sides of the guide seat 1. First, the position of the inner support plate 74 is adjusted according to the depth of the inner cavity of the storage bottle. During adjustment, the movable piece 752 is first pushed to move to the right to separate the limit block 755 from the limit groove 754, and then the threaded rod 751 is rotated to move the inner support plate 74 left and right, so that the horizontal distance from the right side surface of the left clamping plate 41 to the rightmost end of the right side surface of the inner support plate 74 is equal to the horizontal distance from the left side surface of the bottle mouth to the rightmost end of the inner wall of the lower bottle body, and then the movable piece 752 is released, and the resilience of the reset spring 2 753 is used to push the movable piece 752 to move to the left, so that the limit block 755 is inserted into the corresponding limit groove 754 to prevent the threaded rod 751 from rotating.

[0059] Step 2: Place the bottle mouth into the arc groove 2 12, and place the upper bottle body and the lower bottle body into the arc groove 1 11 from left to right, so that the axes of the bottle mouth, the upper bottle body and the lower bottle body coincide.

[0060] Step 3, drive the bidirectional lead screw 522 and the gear 531 to rotate by driving the motor 1 54, and then the gear 531 drives the rack 532 to move downward, and then the rack 532 drives the connecting rod 221 and the cross plate 222 to move downward, and the cross plate 222 pushes the L-shaped clamping block 21 to move downward through the first compression spring 224, so that the vertical section of the L-shaped clamping block 21 is pressed on the bottle mouth, and the horizontal section is pressed on the upper bottle body and the lower bottle body, ensuring the stability of the bottle mouth, the upper bottle body and the lower bottle body. When the L-shaped clamping block 21 presses the storage bottle, the rack 532 will drive the connecting rod 221 and the cross plate 222 to continue to move downward, so that the bidirectional lead screw 522 can continue to rotate and drive the movable block 523 to move in the direction close to the shell 51.

[0061] Step 4. When the L-shaped clamping block 21 moves downward, the card interface 36 will first contact the top inclined surface of the card joint 31. As the L-shaped clamping block 21 continues to move downward, the card interface 36 can push the card joint 31 to move to the right. When the L-shaped clamping block 21 is completely pressed on the storage bottle, the bottom of the arc plate 35 just contacts the top of the guide seat 1. At this time, the top of the card joint 31 completely enters the card interface 36. The rebound force of the reset spring 33 is used to push the connecting plate 32 to move to the left, so that the top of the card joint 31 can be clamped on the upper end of the card interface 36, thereby locking the L-shaped clamping block 21 and the guide seat 1 together. The arc plate 35 cannot move up and down, thereby improving the firmness of the L-shaped clamping block 21.

[0062] Step 5. When the driving motor 1 54 drives the bidirectional lead screw 522 to rotate, the bidirectional lead screw 522 can drive the movable block 523 and the clamping wall 524 to move toward the center of the shell 51. The clamping wall 524 on the left side drives the left clamping plate 41 to move gradually toward the bottle mouth. The clamping wall 524 on the right side drives the right clamping plate 42 to move leftward toward the lower bottle body through the rotating shaft 525. After the L-shaped clamping block 21 presses the storage bottle, the right clamping plate 42 contacts the lower bottle body and pushes the lower bottle body to move leftward and contact with the upper bottle body. Then, the right clamping plate 42 pushes the lower bottle body and the upper bottle body to move leftward together and contact with the bottle mouth. At the same time, the left clamping plate 41 contacts the left side of the bottle mouth, pushing and clamping the bottle mouth, the upper bottle body and the lower bottle body together.

[0063] When the left clamping plate 41 is used to clamp the bottle mouth, the center rod 71 and the inner support plate 74 pass through the center of the bottle mouth and enter the inner cavity of the upper bottle body and the lower bottle body. When the left clamping plate 41 and the right clamping plate 42 push and clamp the bottle mouth, the upper bottle body and the lower bottle body together, the inner support plate 74 just contacts the inner wall of the lower bottle body to prevent the left clamping plate 41 and the right clamping plate 42 from being too clamped and causing the storage bottle to be deformed. Then, the one-way screw 731 is driven to rotate by the driving motor 2 736, and then the one-way screw 731 drives the slider 732 to move to the right. Then, the slider 732 drives the end of the diagonal support rod 2 735 close to the center rod 71 to approach the end of the diagonal support rod 1 734 close to the center rod 71, so that the diagonal support rod 2 735 and the diagonal support rod 1 734 push the inner support rod 72 outward, so that the inner support rod 72 supports the upper bottle body and the lower bottle body from the inside.

[0064] Step 7, in the initial state, since the pull rope 86 pulls the arc frame 82 upward, the roller 85 is separated from the surface of the storage bottle, which facilitates the placement of the upper bottle body and the lower bottle body of the storage bottle into the arc groove 11. When the connecting rod 221 moves downward, as the pull rope 86 gradually relaxes, the rebound force of the second compression spring 83 is used to push the arc frame 82 downward, so that the roller 85 can be gradually pressed against the surface of the upper bottle body and the lower bottle body, and the rollers 85 are symmetrically distributed on the left and right sides of the weld of the upper bottle body and the lower bottle body. At this time, the welding gun is just aimed at the weld.

[0065] Step eight, the rotating motor 6 drives the rotating shaft 525 and the right clamping plate 42 to rotate, and then the right clamping plate 42 drives the storage bottle and the left clamping plate 41 to rotate together, and then the welding gun welds the welds between the bottle mouth and the upper bottle body and the upper bottle body and the lower bottle body. During the welding process, the roller 85 rolls and presses on both sides of the weld, cooperates with the inner support rod 72 to support the upper bottle body and the lower bottle body, and keeps the two sides of the weld aligned.

[0066] After the welding is completed, the one-way screw 731 is driven by the left clamping plate 41 to rotate in the opposite direction, so that the slider 732 drives the diagonal support rod 2 735 to move to the left, and the inner support rod 72 is retracted and pressed against the outer side of the center rod 71, and the push rod 34 is pushed to move to the right, and then the push rod 34 pushes the connecting plate 32 and the card joint 31 to move to the right, and the lock of the L-shaped clamping block 21 is released, and then the driving motor 1 54 is used to drive the two-way screw 522 to rotate in the opposite direction, so that the movable block 523 drives the clamping wall 524 to move away from the center of the shell 51, so that the left clamping plate 41 and the right The clamping plate 42 releases the left and right clamping of the storage bottle. During the movement of the left clamping plate 41 to the left, the center rod 71 gradually moves out of the storage bottle. At the same time, the gear 531 drives the rack 532 to move upward, and then the rack 532 pushes the connecting rod 221 and the cross plate 222 to move upward, gradually driving the L-shaped clamping block 21 to move upward to release the clamping of the storage bottle, and the connecting rod 221 will also drive the pull rope 86 to tighten upward during the upward movement, so that the pull rope 86 pulls the arc frame 82 and the roller 85 away from the surface of the storage bottle, and then the storage bottle is taken out of the arc groove 11.
