Description

Technical Field

[0001] The invention relates to the technical field of safety valve assembly, and in particular to safety valve assembly equipment. Background Art

[0002] Safety valve is a special branch of valve family. It is special because it is different from other valves that only play the role of opening and closing. More importantly, it plays the role of protecting equipment safety. With the rapid development of my country's economic construction, there are more and more equipment projects with pressure control, including the application of safety valves in the fields of fuel pressure control and gas emission control of spacecraft.

[0003] During the assembly process of the safety valve, the installation of the rubber ring is one of the key steps. The installation of the rubber ring needs to ensure that it fits tightly with the valve body to avoid medium leakage. In the process of installing the safety valve with traditional technology, most of the installation is done manually, which requires a lot of labor, has a slow installation efficiency, and uneven quality.

[0004] In order to solve the drawbacks of manual assembly, automatic assembly equipment is usually used to install rubber rings. For example, Chinese patent CN117182536A discloses a rubber ring assembly device, which realizes automatic installation of rubber rings by setting structures such as an external support mechanism, a set mechanism and a fixed plate, thereby improving work efficiency. However, when installing the rubber ring and the pump body, the patent requires the peripheral wall of the guide cylinder to push the rubber ring downward to make the rubber ring separate from the support mold and transfer to the periphery of the pump body. In the process of installation, the rubber rings will move relative to each other, resulting in wear and tear, which may cause damage to the rubber rings. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0029] An embodiment of a safety valve assembly device of the present invention is as follows Figures 1 to 9 shown.

[0030] A safety valve assembly device is used to assemble a rubber ring 500 on a safety valve body 400, comprising a workbench 100, a bearing platform 200 and a mounting mechanism 300. The bearing platform 200 is mounted on the workbench 100, and the safety valve body 400 is arranged on the bearing platform 200. The mounting mechanism 300 is mounted on the workbench 100, and the mounting mechanism 300 comprises a revolving belt 310 and a supporting cylinder 320. The supporting cylinder 320 is arranged along a first direction, and is located on a side of the safety valve body 400 away from the workbench 100 in the first direction, and the first direction is a vertical direction. The two ends of the supporting cylinder 320 along the first direction are respectively referred to as a first end and a second end, and the first end is located on a side of the second end away from the workbench 100 in the first direction. The two ends of the revolving belt 310 along the first direction are respectively referred to as a head end and a tail end, and the head end is sequentially wound around the first end and the second end along the first direction to form a closed loop with the tail end.

[0031] The side of the rotating belt 310 located in the second direction close to the central axis of the support tube 320 is called the inner ring 311. The second direction is the radial direction of the support tube 320. The side of the rotating belt 310 located in the second direction away from the central axis of the support tube 320 is called the outer ring 312. The inner ring 311 can be mutually sleeved with the safety valve body 400, and the inner ring 311 and the outer ring 312 can move in opposite directions in the first direction. The rubber ring 500 is installed on the rotating belt 310. The rubber ring 500 has an installation state and an assembly state. In the installation state, the rubber ring 500 is located on the side of the inner ring 311 close to the central axis of the support tube 320 in the second direction; in the assembly state, the rubber ring 500 is located on the side of the outer ring 312 away from the central axis of the support tube 320 in the second direction. In the initial state, the rubber ring 500 is in the installation state. The inner ring 311 and the outer ring 312 are away from each other in the first direction, which can switch the rubber ring 500 from the installation state to the assembly state.

[0032] In this embodiment, by providing the mounting mechanism 300, when in use, by mounting the rubber ring 500 on the rotating belt 310, the rubber ring 500 can be driven to move synchronously when the inner ring 311 and the outer ring 312 move away from each other in the first direction, so that the rubber ring 500 rotates around the support tube 320. In addition, since the rubber ring 500 is located on the side of the inner ring 311 close to the central axis of the support tube 320 in the second direction in the initial state, as the inner ring 311 and the outer ring 312 move away from each other in the first direction, the rubber ring 500 will also move from the inner ring 311 to the outer ring 312. The rubber ring 500 is moved synchronously with the rotating belt 310 during the whole assembly process, and the two are in a relatively static state, thereby avoiding possible wear and damage to the rubber ring 500 to a certain extent. In addition, in the process of expanding the rubber ring 500, the deformation amount of the rubber ring 500 is the diameter difference between the inner ring 311 and the outer ring 312, which is relatively small, thereby avoiding excessive deformation of the rubber ring 500.

[0033] In this embodiment, the mounting mechanism 300 further includes a first transmission block 330 and a second transmission block 340. The first transmission block 330 is fixedly mounted on one side of the inner ring 311 of the rotating belt 310, and the first transmission block 330 can move in the first direction to a side away from the workbench 100. The second transmission block 340 is fixedly mounted on one side of the outer ring 312 of the rotating belt 310, and the second transmission block 340 can move in the first direction to a side close to the workbench 100. In the initial state, the first transmission block 330 is located on the side of the second transmission block 340 close to the workbench 100 in the first direction.

[0034] Specifically, the mounting mechanism 300 further includes a supporting rail 350 and a telescopic rod 360. The supporting rail 350 is arranged on the workbench 100. The telescopic rod 360 is arranged on the supporting rail 350. The telescopic rod 360 is driven by a first driving member so that the telescopic rod 360 can move and retract along a first direction. The first transmission block 330 is installed on the telescopic rod 360 and can move with the telescopic movement of the telescopic rod 360. A sliding seat 351 is arranged on the supporting rail 350. The sliding seat 351 is driven by a second driving member so that the sliding seat 351 can slide along the first direction on the supporting rail 350. The second transmission block 340 is installed on the sliding seat 351 and can move synchronously with the sliding seat 351. Both the first driving member and the second driving member are hydraulic telescopic cylinders.

[0035] In this embodiment, by setting the first transmission block 330 and the second transmission block 340, when the first transmission block 330 moves, it can drive the inner ring 311 of the rotating belt 310 to move synchronously, and when the second transmission block 340 moves, it can drive the outer ring 312 of the rotating belt 310 to move synchronously, thereby making the inner ring 311 and the outer ring 312 move away from each other in the first direction.

[0036] In this embodiment, a hanging ring assembly is provided on the rotating belt 310, and the hanging ring assembly includes a plurality of hooks 370, and the plurality of hooks 370 are evenly distributed on the rotating belt 310 around the first direction, and the hook 370 has a concave surface and a convex surface, and the concave surface and the convex surface are arranged in sequence in the first direction. In the initial state, the concave surface of the hook 370 is located on the side of the convex surface away from the workbench 100 in the first direction, and when the hook 370 is located at the inner ring 311 of the rotating belt 310, the rubber ring 500 is installed on the plurality of hooks 370 and is in a natural state, and when the hook 370 is located at the outer ring 312 of the rotating belt 310, the rubber ring 500 is installed on the plurality of hooks 370 and is in a tensioned state.

[0037] Furthermore, the hook 370 is elastic, so that the hook 370 can be deformed under pressure when passing through the safety valve body 400, and can be reset after passing through the safety valve body 400, thereby facilitating adaptation to safety valve bodies 400 of different sizes.

[0038] In this embodiment, a hook 370 is provided. When the hook 370 is located at the inner ring 311 of the rotating belt 310, the rubber ring 500 can be supported to prevent the rubber ring 500 from moving in the first direction. When the hook 370 of the inner ring 311 moves to the outer ring 312, the rubber ring 500 can be temporarily fixed on the rotating belt 310 through its own tension force and continue to move with the rotating belt 310 under the urging of the hook 370.

[0039] In this embodiment, a plurality of hanging loop assemblies are provided, and the plurality of hanging loop assemblies are evenly divided into two hanging loop parts, each hanging loop part includes three hanging loop assemblies, and in the initial state, one of the hanging loop parts is provided on the inner ring 311 of the rotating belt 310, and the plurality of hanging loop assemblies of the hanging loop part are arranged sequentially in the first direction. The other hanging loop part is provided on the outer ring 312 of the rotating belt 310, and the plurality of hanging loop assemblies of the hanging loop part are arranged sequentially in the first direction.

[0040] Furthermore, the rotating belt 310 includes a plurality of first belt bodies 313 and a plurality of second belt bodies 314, the plurality of first belt bodies 313 and the plurality of second belt bodies 314 are evenly distributed around the first direction, and the first belt bodies 313 and the second belt bodies 314 are alternately distributed in sequence around the first direction and fixedly connected, the hardness of the first belt body 313 is greater than the hardness of the second belt body 314, a plurality of hooks 370 are arranged one by one corresponding to the plurality of first belt bodies 313, and each hook 370 is installed on the first belt body 313 to which it is correspondingly arranged.

[0041] Specifically, a third driving member is provided on the workbench 100, and the carrier 200 is installed on the output shaft of the third driving member, so that the carrier 200 can be arranged to rotate around the first direction, and the third driving member is a motor. A plurality of safety valve bodies 400 are provided on the carrier 200, and the plurality of safety valve bodies 400 are evenly distributed around the first direction on the carrier 200. And the plurality of safety valve bodies 400 are installed on the carrier 200 through a fourth driving member, so that the safety valve bodies 400 can move along the first direction toward or away from the side of the rotary belt 310, and the fourth driving member is a hydraulic telescopic cylinder.

[0042] In this embodiment, a plurality of hanging ring assemblies are provided. When in use, the safety valve body 400 to be installed and the inner ring 311 of the rotating belt 310 are first connected to each other through the fourth driving member. As the rotating belt 310 moves, the plurality of rubber rings 500 located on the hanging ring portion of the outer ring 312 of the rotating belt 310 will be respectively installed on the corresponding safety valve body 400, and the plurality of rubber rings 500 located on the hanging ring portion of the inner ring 311 of the rotating belt 310 will be respectively installed on the corresponding hanging ring assemblies. That is, while the installation of the rubber ring 500 on the safety valve body 400 is completed, the rubber ring 500 is loaded, thereby improving the working efficiency. After each rubber ring 500 is installed, the fourth driving member is started again to move the installed safety valve body 400 along the first direction to be separated from the inner ring 311 of the rotating belt 310, and then the third driving member is started to drive the supporting platform 200 to rotate around the first direction, and drive the safety valve body 400 to be installed thereon to rotate, and then the fourth driving member is used again to make the safety valve body 400 to be installed and the inner ring 311 of the rotating belt 310 mutually engage with each other to carry out the next assembly, and this cycle is repeated.

[0043] By making the hardness of the first belt body 313 on which the hook 370 is installed greater than the hardness of the second belt body 314 on which the hook 370 is not installed, it is possible to prevent the first belt body 313 from being excessively deformed by the force of the hook 370 .

[0044] In this embodiment, the output end of the telescopic rod 360 is connected to the suction cup 380 through an air pump. When the air pump is started, the air pump will draw air from the suction cup 380, so that the suction cup 380 can adsorb the first transmission block 330, and then the first transmission block 330 can move with the telescopic rod 360. When the air pump stops, the suction cup 380 will be separated from the first transmission block 330.

[0045] Furthermore, the second transmission block 340 can rotate around the second direction relative to the sliding seat 351 and move synchronously with the sliding seat 351 along the first direction.

[0046] Specifically, an annular protrusion is provided on the outer peripheral wall of the second transmission block 340, and a groove for cooperating with the annular protrusion is provided on the sliding seat 351. The annular protrusion is rotatably installed in the groove, so that the second transmission block 340 can rotate around the second direction relative to the sliding seat 351 and move synchronously along the first direction with the sliding seat 351. A fifth driving member is provided on the workbench 100, and the fifth driving member is used to drive the second transmission block 340 to rotate around the second direction. The fifth driving member is a motor.

[0047] By setting the suction cup 380, this embodiment can be used. When the telescopic rod 360 is needed to drive the first transmission block 330 to move, it is only necessary to start the air pump and use the suction cup 380 to absorb the first transmission block 330. When the telescopic rod 360 needs to be separated from the first transmission block 330, it is only necessary to stop the air pump, and then the telescopic rod 360 can move relative to the first transmission block 330.

[0048] In this embodiment, a plurality of rollers 390 are respectively disposed at both ends of the support cylinder 320 along the first direction, and the plurality of rollers 390 are evenly distributed on the support cylinder 320 along the first direction, and the rollers 390 can rotate around a reference axis, and the reference axis is along the tangent direction of the support cylinder 320. The head end of the rotary belt 310 is sequentially wound around the rollers 390 at the first end and the rollers 390 at the second end along the first direction, and then forms a closed loop with the tail end.

[0049] In this embodiment, by disposing a plurality of rollers 390 on both ends of the support tube 320 along the first direction, the friction between the revolving belt 310 and the support tube 320 can be reduced, thereby making the revolving belt 310 easier to move.

[0050] In combination with the above embodiments, the specific working process is as follows:

[0051] In the initial state, no rubber ring 500 is installed on the two hanging ring parts, and the state diagram of the installation mechanism 300 in the initial state is shown in the attached figure. Figure 4 As shown, when in use, first place a plurality of rubber rings 500 (the same number as the hanging ring components, specifically 3) on the inner ring 311 of the rotary belt 310, then start the first driving member and the air pump, the air pump absorbs the first transmission block 330, and drives the first transmission block 330 to move along the first direction to the side away from the workbench 100 through the telescopic rod 360, so that the inner ring 311 of the rotary belt 310 moves along the first direction to the side away from the workbench 100, and at the same time, start the second driving member to drive the second transmission block 340 to move along the first direction to the side close to the workbench 100 through the sliding seat 351, and move the outer ring 312 of the rotary belt 310 along the first direction to the side close to the workbench 100, during the movement, the plurality of rubber rings 500 will be respectively installed on the corresponding hanging ring components until the entire installation mechanism 300 is in the attached Figure 6 Status shown.

[0052] Then, the air pump is turned off, and the telescopic rod 360 is separated from the rotating belt 310 by the first driving member, and then the second transmission block 340 is driven by the fifth driving member to rotate 180° around the second direction relative to the sliding seat 351. At this time, the entire installation mechanism 300 is in the attached Figure 4In the state shown, a rubber ring 500 has been hung on the hanging ring portion located at the lower side, and then a plurality of rubber rings 500 (the same number as the hanging ring portions) are placed on the inner ring 311 of the rotating belt 310.

[0053] When the inner ring 311 and the outer ring 312 move away from each other in the first direction, the rubber ring 500 will be driven to move synchronously, so that the rubber ring 500 rotates around the support tube 320. During the rotation, the rubber ring 500 of the inner ring 311 will come to the outer ring 312, increasing the deformation and tension of the rubber ring 500 and stretching the rubber ring 500. When the rubber ring 500 of the outer ring 312 moves to the intersection of the inner ring 311 and the outer ring 312 on the second end side of the support tube 320, the rubber ring 500 will be separated from the rotating belt 310 under the action of its own tension and be sleeved on the safety valve body 400. During the entire assembly process, the rubber ring 500 moves synchronously with the rotating belt 310, and the two are in a relatively static state, thereby avoiding possible wear and damage to the rubber ring 500 to a certain extent.

[0054] After completing the installation of a rubber ring 500, while the inner ring 311 and the outer ring 312 of the rotating belt 310 are moving, the installed safety valve body 400 is moved along the first direction to the side close to the workbench 100 to be separated from the rotating belt 310, and then the supporting platform 200 is driven to rotate around the first direction to the next safety valve body 400, and the safety valve body 400 is moved along the first direction to the side close to the workbench 100 to be engaged with the inner ring 311 of the rotating belt 310, and the cycle is repeated.

[0055] When the multiple (3) hanging ring assemblies of the outer ring 312 have completed the installation of the rubber ring 500, the installation mechanism 300 comes to the adjacent Figure 6 The air pump is then turned off, and the telescopic rod 360 is disengaged from the rotating belt 310 by the first driving member, and then the second transmission block 340 is driven by the fifth driving member to rotate 180° around the second direction relative to the sliding seat 351 to reset. After the reset, the mounting mechanism 300 comes to the adjacent Figure 4 In the state shown, the rubber ring 500 can be assembled.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
