A temporary filling mechanism for sidewall holes during the assembly process of tubular products

Abstract

This invention provides a temporary filling mechanism for sidewall holes during the assembly of tubular products. It includes a drive cylinder, a pull rod, an inclined wedge, a sealing component, an outer cylinder, a lifting cylinder, a housing, and positioning grippers. The key feature is that the drive cylinder drives the inclined wedge via the pull rod, and the inclined wedge, through inclined surface transmission, causes the sealing component to slide radially along the outer cylinder. The lifting cylinder controls the lifting and lowering of the outer cylinder, moving the sealing component to the position of the product's sidewall hole to complete the sealing. This effectively protects the O-ring seal, preventing scratching of the seal by the edge of the sidewall hole during assembly, thus improving assembly quality. The precise transmission of the inclined wedge ensures accurate radial movement of the sealing component. The mechanism has a high degree of automation and is suitable for mass production.

Description

Technical Field

[0001] This invention relates to the field of mechanical assembly technology, and in particular to a temporary filling mechanism for sidewall holes during the assembly process of tubular products. Background Technology

[0002] Pipe products are widely used in machinery, petrochemical, and automotive industries. During their production and assembly, O-rings are often required for sealing. However, pipe products with sidewall holes typically have prominent edges. These edges can scratch the O-rings during assembly, causing damage and affecting the sealing effect, or even leading to seal failure.

[0003] In existing technologies, some companies use manual trimming of the sidewall hole edges, but this method is inefficient, costly, and prone to inconsistencies in human operation. Furthermore, some mechanical assembly methods lack targeted sealing mechanisms, making it easy for inaccurate positioning or poor design of the sealing components during assembly to damage the sealing ring from the sidewall hole, further reducing assembly quality.

[0004] Currently, there is no efficient and automated temporary sealing mechanism for sidewall holes on the market that can effectively solve the above problems. Therefore, designing an assembly mechanism that can accurately seal sidewall holes and protect O-ring seals has become an urgent need. Summary of the Invention

[0005] The purpose of this invention is to provide a temporary filling mechanism for side wall holes during the assembly process of pipe products, so as to temporarily seal the side wall holes, avoid the edges from scraping the O-ring seal, and thus improve the assembly quality and sealing effect.

[0006] This invention is achieved using the following technical solution: a temporary filling mechanism for side wall holes during the assembly process of tubular products, comprising a drive cylinder, a pull rod, an inclined wedge, a sealing component, an outer cylinder, a lifting cylinder, a housing, and positioning grippers, characterized in that: the drive cylinder drives the inclined wedge through the pull rod, and the inclined wedge causes the sealing component to slide radially along the outer cylinder through inclined surface transmission; the lifting cylinder controls the lifting and lowering of the outer cylinder, moving the sealing component to the position of the product side wall hole to complete the sealing.

[0007] Furthermore, the outer wall of the sealing component is flush with the outer wall of the product.

[0008] Furthermore, a guide head is provided at the top of the outer cylinder to help the outer cylinder be inserted into the inner cavity of the product.

[0009] Furthermore, the positioning gripper is driven by a clamping cylinder to clamp and fix the product.

[0010] Furthermore, both the drive cylinder and the lifting cylinder are mounted on the outer casing.

[0011] Furthermore, the inclined wedge and the sealing member are slidably connected.

[0012] Furthermore, the sealing element and outer cylinder have multiple replacement components to adapt to pipe products of different specifications.

[0013] The temporary filling mechanism for sidewall holes during the assembly process of tubular products described in this invention has the following advantages:

[0014] Effective protection of O-ring seals: Prevents the sidewall hole edges from scratching the seals during assembly, thus improving assembly quality.

[0015] High assembly precision: The precise transmission of the inclined wedge ensures accurate radial movement of the sealing component.

[0016] Easy to operate: The mechanism is highly automated and suitable for mass production. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0024] like Figure 1-3 As shown, a temporary filling mechanism for side wall holes in the assembly process of tubular products includes a drive cylinder 1, a pull rod 2, an inclined wedge 8, a sealing component 9, an outer cylinder 3, a lifting cylinder 7, a housing 4, and a positioning gripper 6. The drive cylinder 1 drives the inclined wedge 8 through the pull rod 2, and the inclined wedge 8 causes the sealing component 9 to slide radially along the outer cylinder 3 through inclined surface transmission. The lifting cylinder 7 controls the lifting and lowering of the outer cylinder 3, moving the sealing component 9 to the position of the side wall hole of the product to complete the sealing.

[0025] A drive cylinder 1 provides axial tension, driving the inclined wedge 8 via a pull rod 2. One end of the pull rod 2 is connected to the drive cylinder 1, and the other end is connected to the inclined wedge 8, transmitting the driving force. The inclined wedge 8 is connected to the pull rod 2, and slides along the inclined surface to push the sealing member 9 to move radially. The sealing member 9 is located inside the outer cylinder 3 and can slide radially to seal the side wall holes of the product. The outer cylinder 3 houses the sealing member 9, and its position is controlled by a lifting cylinder 7. The lifting cylinder 7 controls the lifting and lowering of the outer cylinder 3, moving the sealing member 9 to the position to be sealed. The outer shell 4 supports the drive cylinder 1, the lifting cylinder 7, and other components, forming the main frame of the mechanism. A clamping cylinder mounting plate 5 is used to mount the clamping cylinder, providing a clamping function. The positioning gripper 6 is driven by the clamping cylinder and is used to clamp and position the product 11. A guide head 10 is located at the top of the outer cylinder 3 to guide the outer cylinder to smoothly insert into the inner cavity of the product. Product 11 is a tubular product with side wall holes. After the outer wall 12 of the product and the outer wall 13 of the sealing component are sealed, they are on the same plane.

[0026] During operation, the clamping cylinder mounting plate 5 drives the clamping cylinder, which clamps the outer wall 12 of the product via the positioning jaws 6, fixing the product 11 in a stable position, ready for assembly. The lifting cylinder 7 retracts, causing the outer cylinder 3 to descend, and the guide head 10 guides the outer cylinder 3 through the inner cavity of the product 11 for insertion. During the movement of the outer cylinder 3, the mechanism is kept coaxial with the product 11 to ensure the precise positioning of the sealing component 9. The driving cylinder 1 retracts, pulling the pull rod 2. The pull rod 2 slides along the inclined surface of the inclined wedge 8, pushing the sealing component 9 to slide radially along the outer cylinder 3. The circular head of the sealing component 9 inserts into the side wall hole of the product, and the outer wall 13 of the sealing component is flush with the outer wall 12 of the product, completing the temporary sealing. The sealing component 9 effectively fills the side wall hole, preventing the edge of the side wall hole from scraping the O-ring seal, thus protecting the integrity of the seal. After assembly is completed, the driving cylinder 1 reverses its movement, the inclined wedge 8 returns to its initial position, and the sealing component 9 retracts radially into the outer cylinder 3. The lifting cylinder 7 drives the outer cylinder 3 to rise, and the mechanism retracts from the inner cavity of the product.

[0027] The above embodiments describe the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Modifications and variations made by those skilled in the art without departing from the spirit and scope of the invention should be within the protection scope of the appended claims.
