Description

Technical Field

[0001] The invention relates to the technical field of mechanical assembly, and in particular to a temporary filling mechanism for side wall holes in the assembly process of a pipe product. Background Art

[0002] Tube products are widely used in machinery, petrochemical, automotive and other fields. During their production and assembly, they often need to be sealed with O-rings. However, tube products with sidewall holes usually have obvious edges, which will scratch the O-rings during assembly, causing damage to the rings, which in turn affects the sealing effect and even causes sealing failure.

[0003] In the prior art, some companies have adopted the method of manually trimming the edges of the side wall holes, but this method is inefficient, costly, and has the problem of inconsistent manual operation. In addition, some mechanical assembly methods lack targeted plugging mechanisms. During the assembly process, it is easy for the side wall holes to damage the sealing rings due to inaccurate positioning of the plugging parts or unreasonable design of the plugging parts, further reducing the assembly quality.

[0004] At present, there is no efficient and automated temporary plugging mechanism for the side wall holes on the market that can effectively solve the above problems. Therefore, it is urgent to design an assembly mechanism that can accurately plug the side wall holes and protect the O-ring. Summary of the invention

[0005] The purpose of the present invention is to provide a temporary filling mechanism for side wall holes during the assembly process of pipe products, so as to achieve temporary blocking of the side wall holes and avoid edges from scratching O-rings, thereby improving assembly quality and sealing effect.

[0006] The present invention is implemented by adopting the following technical scheme: a temporary filling mechanism for the side wall holes in the assembly process of pipe products, including a driving cylinder, a pull rod, a bevel wedge, a sealing piece, an outer tube, a lifting cylinder, an outer shell and a positioning clamp, characterized in that: the driving cylinder drives the bevel wedge through the pull rod, and the bevel wedge drives the sealing piece to slide radially along the outer tube through the bevel transmission; the lifting cylinder controls the lifting and lowering of the outer tube to move the sealing piece to the position of the side wall hole of the product to complete the sealing.

[0007] Furthermore, the outer wall of the blocking member is flush with the outer wall of the product.

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

[0009] Furthermore, the positioning clamping claw is driven by a clamping cylinder to achieve clamping and fixing of the product.

[0010] Furthermore, the driving cylinder and the lifting cylinder are both installed on the outer shell.

[0011] Furthermore, the inclined wedge piece and the blocking piece are connected by sliding.

[0012] Furthermore, the plugging piece and the outer tube have replacement components of various specifications to adapt to pipe products of different specifications.

[0013] The temporary filling mechanism for side wall holes in the assembly process of a pipe product described in the present invention has the following beneficial effects: Effectively protect the O-ring: avoid the scratching of the sealing ring by the edge of the side wall hole during assembly, and improve the assembly quality.

[0014] High assembly precision: accurate radial movement of the plugging piece is ensured through precise transmission of the inclined wedge.

[0015] Easy to operate: The mechanism has a high degree of automation and is suitable for mass production. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. 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.

[0020] like Figure 1-3 As shown, a temporary filling mechanism for side wall holes in the assembly process of a tube product includes a driving cylinder 1, a pull rod 2, a bevel wedge 8, a sealing piece 9, an outer tube 3, a lifting cylinder 7, an outer shell 4 and a positioning clamp 6. The driving cylinder 1 drives the bevel wedge 8 through the pull rod 2, and the bevel wedge 8 causes the sealing piece 9 to slide radially along the outer tube 3 through the bevel transmission; the lifting cylinder 7 controls the lifting and lowering of the outer tube 3 to move the sealing piece 9 to the position of the side wall hole of the product to complete the sealing.

[0021] The driving cylinder 1 is used to provide axial tension and drive the inclined wedge 8 through the pull rod 2. One end of the pull rod 2 is connected to the driving cylinder 1, and the other end is connected to the inclined wedge 8 to transmit the driving force. The inclined wedge 8 is connected to the pull rod 2, and pushes the blocking piece 9 to move radially through the inclined sliding. The blocking piece 9 is arranged in the outer tube 3 and can slide radially to block the side wall hole of the product. The outer tube 3 accommodates the blocking piece 9 and controls its position through the lifting cylinder 7. The lifting cylinder 7 controls the lifting and lowering of the outer tube 3 to move the blocking piece 9 to the position to be blocked. The outer shell 4 supports the driving cylinder 1, the lifting cylinder 7 and other components to form the main frame of the mechanism. The clamping cylinder mounting plate 5 is used to install the clamping cylinder and provide a clamping function. The positioning jaw 6 is driven by the clamping cylinder and is used to clamp and position the product 11. The guide head 10 is arranged at the top of the outer tube 3 to guide the outer tube to be smoothly inserted into the inner cavity of the product. Product 11 is a tube product with side wall holes. After the product outer wall 12 and the sealing member outer wall 13 are sealed, the two are in the same plane.

[0022] During operation, the clamping cylinder mounting plate 5 drives the clamping cylinder to clamp the outer wall 12 of the product through the positioning claw 6, fix the product 11 to keep it stable, and prepare for assembly. The lifting cylinder 7 contracts, driving the outer cylinder 3 to descend, and the guide head 10 guides the outer cylinder 3 to be inserted through the inner cavity of the product 11. During the movement of the outer cylinder 3, the mechanism is ensured to remain coaxial with the product 11 to ensure the precise positioning of the plugging piece 9. The driving cylinder 1 contracts and pulls the pull rod 2, which slides through the inclined surface of the inclined wedge 8 and pushes the plugging piece 9 to slide radially along the outer cylinder 3. The round head of the plugging piece 9 is inserted into the side wall hole of the product, and the outer wall 13 of the plugging piece is flush with the outer wall 12 of the product, completing the temporary plugging. The plugging piece 9 effectively fills the side wall hole, preventing the edge of the side wall hole from scratching the O-ring, thereby protecting the integrity of the sealing ring. After the assembly is completed, the driving cylinder 1 moves in the opposite direction, the inclined wedge 8 returns to its initial position, and the plugging piece 9 retracts radially into the outer cylinder 3. The lifting cylinder 7 drives the outer tube 3 to rise, and the mechanism withdraws from the product cavity.

[0023] The above embodiments describe the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the changes and modifications made by those skilled in the art shall be within the scope of protection of the appended claims of the present invention without departing from the spirit and scope of the present invention.
