Description

Technical Field

[0001] This invention relates to the technical field of fitting a sealing ring into the annular groove of each of the two branch pipes of a tubular product, and in particular to a highly efficient fitting device and method for fitting sealing rings onto the two branch pipes of a tubular product. Background Technology

[0002] Workers in a certain workshop produced a batch of products like Figures 1-2 The pipe product shown is used to be installed on a valve body to facilitate fluid flow. The pipe product includes a branch pipe 2 welded to the top surface of the pipe body 1 and at its left and right ends. The cross-section of the pipe body 1 is rectangular, and the two branch pipes 2 are cylindrical and connected to the pipe body 1. An annular groove 3 is opened on the outer cylindrical surface of the two branch pipes 2.

[0003] After a batch of these pipe products is produced in the workshop, the process requires that a [missing information - likely a type of fitting] be installed in the annular groove 3 of each of the two branch pipes 2 of each pipe product. Figures 3-4 The sealing ring 4 shown is made of elastic rubber. The structure of a tubular product with two sealing rings 4 is as follows: Figure 5 As shown.

[0004] The method by which workers in the workshop install a sealing ring 4 in the annular groove 3 of each of the two branch pipes 2 of the tubular product is as follows: R1, The worker takes out a... Figures 1-2 The tubular product shown is supported on the table surface by the tubular body 1. R2, The worker takes out a... Figures 3-4 As shown, the sealing ring 4 is opened outwards by hand, and then the opened sealing ring 4 is pre-fitted onto the left branch pipe 2 of the tubular product, as follows. Figure 6 As shown, the sealing ring 4 is then pushed downward by hand so that it moves downward along the branch pipe 2. When the sealing ring 4 is pushed to the annular groove 3 of the left branch pipe 2, the sealing ring 4, which is in an open state, contracts inward to hold the annular groove 3 tightly, thereby realizing the installation of a sealing ring 4 on the left branch pipe 2 of the pipe product. R3. The worker repeats step R2 once to install a sealing ring 4 on the right branch pipe 2 of the pipe product. This ultimately ensures that a sealing ring 4 is installed in the annular groove 3 of both branch pipes 2 of the first pipe product. Figure 5 The diagram shows a structural schematic of a tubular product with two sealing rings 4. R4. Workers repeat steps R2 to R3 multiple times to install sealing rings 4 on both branch pipes 2 of multiple pipe products.

[0005] However, although the method used in the workshop can fit a sealing ring 4 on both branch pipes 2 of the tubular product, it still has the following technical defects: I. In step R2, the worker needs to manually push the sealing ring 4 outward first, and then put the pushed sealing ring 4 on the branch pipe 2 of the pipe product. Then, the worker needs to push the sealing ring 4 downward by hand in order to put a sealing ring 4 on the left branch pipe 2 of the pipe product. The entire operation is done manually by workers, which undoubtedly increases their workload. In addition, the many steps involved in the operation result in a long time required to install a sealing ring 4 on a branch pipe 2, which undoubtedly reduces the efficiency of installing sealing rings 4 on pipe products.

[0006] II. In steps R2 to R3, workers need to perform two separate processes to install a sealing ring 4 on each of the two branch pipes 2 of the tubular product. However, there are hundreds of tubular products in the workshop that need to have sealing rings installed. This method of installing the sealing rings in two separate processes results in a long time to install the sealing rings 4 on each of the two branch pipes 2 of a batch of tubular products. This undoubtedly further reduces the efficiency of installing the sealing rings 4 on the tubular products.

[0007] Therefore, there is an urgent need for a device and method for fitting sealing rings on pipe products that can greatly reduce the workload of workers and greatly improve the efficiency of fitting sealing rings. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide an efficient device for fitting sealing rings onto two pipes of a tubular product.

[0009] The objective of this invention is achieved through the following technical solution: a high-efficiency device for fitting sealing rings onto two pipes of a tubular product, comprising a worktable and a lifting cylinder fixed to the bottom surface of the worktable. The piston rod of the lifting cylinder extends upward through the worktable, and a strip-shaped seat is fixed to its extended end. A horizontally arranged strip-shaped positioning groove is formed on the top surface of the strip-shaped seat, and the strip-shaped positioning groove matches the outer contour of the tubular product. An arched frame is fixed on the worktable and mounted directly above the strip-shaped seat. A floating driving component for pushing the sealing ring downward is provided on the bottom surface of the crossbeam of the arched frame at both its left and right ends. The kit also includes two guide components for connecting to the branch pipe of the tubular product. The guide components include a conical head, a cylindrical head, and an insert block that are fixed together from top to bottom. The conical head, cylindrical head, and insert block are coaxial. The diameter of the cylindrical head is equal to the outer diameter of the branch pipe of the tubular product, and the diameter of the insert block is equal to the inner diameter of the branch pipe.

[0010] Multiple support legs, which are fixed to the ground, are fixed on the bottom surface of the workbench.

[0011] The depth of the strip positioning groove of the strip seat is less than the height of the tube body of the tube product.

[0012] The floating driving assembly located at the left end of the arched frame includes two upright plates fixed to the bottom surface of the crossbeam of the arched frame. A fixed rod slides through each of the two upright plates, and an L-shaped floating driving plate is slidably fitted on each of the two fixed rods. A spring is fitted on each of the two fixed rods, and the left and right ends of the springs are fixed between the upright plates and the floating driving plates, respectively.

[0013] The fixed rod has a rectangular cross-section, and the floating driving plate has a guide groove inside, through which the floating driving plate is slidably sleeved on the fixed rod.

[0014] The two floating drive components are symmetrical about the bar seat.

[0015] The kit also includes a controller, which is electrically connected to the lifting cylinder via a signal line.

[0016] A method for efficiently installing sealing rings on two pipes of a tubular product includes the following steps: S1. Positioning of tubular products, the specific operational steps are as follows: S11. The worker takes a tubular product out of the material basket; S12. Insert the tube body of the tube product into the strip positioning groove of the strip seat from top to bottom, thereby achieving the positioning of the tube product. At this time, the left branch tube of the tube product is located directly below the area enclosed by the two floating driving plates of the left floating driving component, and the right branch tube of the tube product is located directly below the area enclosed by the two floating driving plates of the right floating driving component. S2. The worker takes out a guide component and inserts the guide component's insert from top to bottom into the inner cavity of the left branch pipe of the pipe product, ensuring that the cylindrical head of the guide component is supported on the top surface of the branch pipe, thereby installing a guide component onto the left branch pipe of the pipe product. S3. The worker repeats step S2 once to install the second guide assembly onto the right branch of the pipe product. S4. The worker takes out two sealing rings and initially puts the two sealing rings on the conical heads of the two guide components. At this time, the sealing rings are just suspended on the conical surface of the conical head. S5. The worker controls the piston rod of the lifting cylinder to extend upward, the piston rod drives the strip seat to move upward, the strip seat drives the tubular product to move upward, the tubular product drives the two guide components to move upward synchronously, and the two guide components drive the sealing ring initially fitted on them to move upward synchronously. When the piston rod of the lifting cylinder extends to a certain distance, the lower edges of the two floating driving plates of the floating driving assembly come into contact with the conical surface of the conical head of the guide assembly. At the same time, the bottom surfaces of the two floating driving plates come into contact with the top surface of the sealing ring. As the piston rod of the lifting cylinder continues to extend upward, the two floating drive plates of the floating drive assembly gradually drive the sealing ring downward. At this time, the sealing ring is gradually pushed outward by the conical surface of the conical head. Simultaneously, under the push of the conical surface of the conical head, the floating drive plate moves along the fixed rod gradually away from the conical head, and the floating drive plate also gradually compresses the spring. As the piston rod of the lifting cylinder continues to extend upward, the opened sealing ring is driven to the cylindrical head of the guide assembly. At the same time, the inner end faces of the two floating driving plates of the floating driving assembly come into contact with the cylindrical surface of the cylindrical head. At this time, the sealing ring is in a fully opened state. As the piston rod of the lifting cylinder continues to extend upward, the fully extended sealing ring is driven onto the branch pipe of the tubular product. As the piston rod of the lifting cylinder continues to extend upward, the sealing ring moves toward the annular groove of the branch pipe; When the piston rod of the lifting cylinder is fully extended, the sealing ring is just driven to the annular groove of the branch pipe. At this time, the sealing ring, which is in a fully extended state, contracts inward and holds the annular groove of the branch pipe tightly, thus finally achieving the goal of fitting a sealing ring in the annular groove of both branch pipes of the pipe product. S6. The specific steps for removing tubular products with two sealing rings are as follows: S61. The worker controls the piston rod of the lifting cylinder to retract downwards. The piston rod drives the strip seat to move downwards, the strip seat drives the tubular product to move downwards, and the tubular product drives the two guide components to move downwards synchronously. During the downward movement, under the action of the spring elastic restoring force, the floating drive plate resets along the fixed rod. S62. After the piston rod of the lifting cylinder is fully retracted, the strip seat and the tubular product move to the initial position. The worker removes the two guide components from the branch pipe of the tubular product. Finally, the worker removes the tubular product with two sealing rings from the strip seat. S7. Workers repeat steps S2 to S6 multiple times to install sealing rings on both branch pipes of multiple pipe products.

[0017] The present invention has the following advantages: it greatly reduces the workload of workers and greatly improves the efficiency of installing sealing rings on pipe products. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description: like Figures 6-17 As shown, a high-efficiency device for fitting sealing rings onto two pipes of a tubular product includes a worktable 5 and a lifting cylinder 6 fixed to the bottom surface of the worktable 5. Multiple support feet, supported on the ground, are fixed to the bottom surface of the worktable 5. The piston rod of the lifting cylinder 6 extends upward through the worktable 5, and a strip-shaped seat 7 is fixed to its extended end. A horizontally positioned strip-shaped positioning groove 8 is formed on the top surface of the strip-shaped seat 7. The depth of the strip-shaped positioning groove 8 is less than the height of the pipe body 1 of the tubular product, and the strip-shaped positioning groove 8 matches the outer contour of the pipe body 1. An arched frame 9 is fixed on the worktable 5, directly above the strip-shaped seat 7. A floating driving component 10, which pushes the sealing ring 4 downwards, is installed on the bottom surface of the crossbeam of the arched frame 9 at both its left and right ends. The two floating driving components 10 are symmetrical about the strip-shaped seat 7.

[0020] The floating driving assembly 10 located at the left end of the arched frame 9 includes two upright plates 14 fixed to the bottom surface of the crossbeam of the arched frame 9. A fixed rod 15 slides through each of the two upright plates 14. An L-shaped floating driving plate 16 is slidably fitted on each of the two fixed rods 15. A spring 17 is fitted on each of the two fixed rods 15, with the left and right ends of the spring 17 fixed between the upright plate 14 and the floating driving plate 16, respectively. The fixed rod 15 has a rectangular cross-section. The floating driving plate 16 has a guide groove 18, and the floating driving plate 16 is slidably fitted onto the fixed rod 15 through the guide groove 18.

[0021] The kit also includes two guide components for connecting to the branch pipe 2 of the tubular product. The guide components include a conical head 11, a cylindrical head 12 and an insert 13 that are fixed together from top to bottom. The conical head 11, the cylindrical head 12 and the insert 13 are coaxial. The diameter of the cylindrical head 12 is equal to the outer diameter of the branch pipe 2 of the tubular product, and the diameter of the insert 13 is equal to the inner diameter of the branch pipe 2.

[0022] The kit also includes a controller, which is electrically connected to the lifting cylinder 6 via a signal line. The worker can control the extension or retraction of the piston rod of the lifting cylinder 6 through the controller, thereby facilitating the worker's operation.

[0023] A method for efficiently installing sealing rings on two pipes of a tubular product includes the following steps: S1. Positioning of tubular products, the specific operational steps are as follows: S11, The worker takes out a piece from the basket as shown in the image. Figures 1-2 The pipe products shown; S12. The tube body 1 of the tubular product is inserted from top to bottom into the strip positioning groove 8 of the strip seat 7, thereby achieving the positioning of the tubular product. Figure 18 As shown, at this time, the left branch pipe 2 of the pipe product is located directly below the area enclosed by the two floating driving plates 16 of the left floating driving component 10, and at the same time, the right branch pipe 2 of the pipe product is located directly below the area enclosed by the two floating driving plates 16 of the right floating driving component 10. S2, The worker takes out a... Figures 12-13 The guide assembly shown is inserted from top to bottom into the inner cavity of the left branch pipe 2 of the tubular product, ensuring that the cylindrical head 12 of the guide assembly is supported on the top surface of the branch pipe 2. This achieves the installation of a guide assembly onto the left branch pipe 2 of the tubular product. Figure 19 As shown; S3. The worker repeats step S2 once to install the second guide assembly onto the right branch pipe 2 of the pipe product, as follows. Figure 20 As shown; S4, the worker took out two such... Figures 3-4 As shown, the two sealing rings 4 are initially fitted onto the conical heads 11 of the two guide components, as follows. Figure 21 As shown, at this time, the sealing ring 4 is just suspended on the conical surface of the conical head 11; S5. The worker controls the piston rod of the lifting cylinder 6 to extend upward, the piston rod drives the strip seat 7 to move upward, the strip seat 7 drives the tubular product to move upward, the tubular product drives the two guide components to move upward synchronously, and the two guide components drive the sealing ring 4 initially fitted on it to move upward synchronously. When the piston rod of the lifting cylinder 6 extends to a certain distance, the lower edges of the two floating driving plates 16 of the floating driving assembly 10 contact the conical surface of the conical head 11 of the guide assembly. Simultaneously, the bottom surfaces of the two floating driving plates 16 contact the top surface of the sealing ring 4. Figure 22 As shown; As the piston rod of the lifting cylinder 6 continues to extend upward, the two floating driving plates 16 of the floating driving assembly 10 gradually drive the sealing ring 4 downward. At this time, the sealing ring 4 is gradually pushed outward by the conical surface of the conical head 11. Simultaneously, under the push of the conical surface of the conical head 11, the floating driving plate 16 gradually moves along the fixed rod 15 away from the conical head 11, and the floating driving plate 16 also gradually compresses the spring 17. As the piston rod of the lifting cylinder 6 continues to extend upward, the stretched seal ring 4 is driven onto the cylindrical head 12 of the guide assembly, as... Figure 23 As shown, at the same time, the inner end faces of the two floating driving plates 16 of the floating driving assembly 10 are in contact with the cylindrical surface of the cylindrical head 12. At this time, the sealing ring 4 is in a fully open state. As the piston rod of the lifting cylinder 6 continues to extend upward, the fully extended sealing ring 4 is driven onto the branch pipe 2 of the tubular product, such as... Figure 24 As shown; As the piston rod of the lifting cylinder 6 continues to extend upward, the sealing ring 4 moves toward the annular groove 3 of the branch pipe 2; When the piston rod of the lifting cylinder 6 is fully extended, the sealing ring 4 is just driven to the annular groove 3 of the branch pipe 2. At this time, the sealing ring 4, which is in a fully extended state, contracts inward and holds the annular groove 3 of the branch pipe 2 tightly. Thus, a sealing ring is finally installed in the annular groove 3 of both branch pipes 2 of the pipe product. Figure 25 As shown, the structure of the tubular product with two sealing rings 4 is as follows: Figure 5 As shown; As can be seen from step S5, the worker only needs to control the piston rod of the lifting cylinder 6 to extend upward so that the tubular product and the guide assembly move towards the floating drive assembly 10. This will automatically open the sealing ring 4 outward, automatically drive the sealing ring 4 downward, and automatically fit the sealing ring 4 into the annular groove 3 of the branch pipe 2 of the tubular product.

[0024] Therefore, it can be seen that this kit is superior to... Figure 6 The installation method shown eliminates the need for workers to manually expand the sealing ring 4 outwards, pre-install the expanded sealing ring 4 onto the branch pipe 2 of the tubular product, or manually drive the sealing ring 4 downwards. Instead, it automatically installs the sealing ring 4 into the annular groove 3 of the branch pipe 2 of the tubular product, thereby greatly improving the efficiency of installing sealing rings on tubular products.

[0025] S6. The specific steps for removing tubular products with two sealing rings (4) are as follows: S61, the worker controls the piston rod of the lifting cylinder 6 to retract downwards, the piston rod drives the strip seat 7 to move downwards, the strip seat 7 drives the tubular product to move downwards, the tubular product drives the two guide components to move downwards synchronously, during the downward movement, under the action of the elastic restoring force of the spring 17, the floating drive plate 16 resets along the fixed rod 15. S62. After the piston rod of the lifting cylinder 6 is fully retracted, the strip seat 7 and the tubular product move to their initial positions, such as... Figure 26 As shown, the worker removes the two guide components from the branch pipe 2 of the tubular product. Finally, the worker removes the tubular product with two sealing rings 4 from the strip seat 7, in the following direction. Figure 27 As indicated by the solid arrow in the center; S7. Workers repeat steps S2 to S6 multiple times to install sealing rings 4 on both branch pipes 2 of multiple pipe products.

[0026] Furthermore, in step S1, the tube body 1 of the tubular product is first embedded into the strip seat 7 to achieve positioning of the tubular product; then in steps S2-S3, the two guide components are respectively installed on the two branch pipes 2 of the tubular product; then in step S4, the two sealing rings 4 are initially fitted onto the conical heads 11 of the two guide components; finally, in step S5, the piston rod of the lifting cylinder 6 is controlled to extend upward, so that the tubular product and the two guide components move upward synchronously, thereby ultimately achieving the installation of a sealing ring 4 in the annular groove 3 of the two branch pipes 2 of the tubular product.

[0027] Therefore, it can be seen that this kit is superior to... Figure 6The assembly method shown eliminates the need for workers to perform two separate processes to assemble the sealing rings 4 onto the two branch pipes 2 of the tubular product. Instead, it achieves this by using the coordinated operation of the lifting cylinder 6, two guide components, and two floating drive components 10 to assemble a sealing ring 4 into the annular groove 3 of both branch pipes 2 of the tubular product in one go. This allows for the assembly of sealing rings 4 onto the two branch pipes 2 of a batch of tubular products in a short time, thereby significantly improving the efficiency of assembling sealing rings onto tubular products.
