Description

Technical Field

[0001] This utility model relates to the field of pipe fitting processing equipment technology, and in particular to a pipe fitting processing device. Background Technology

[0002] Straight seam welding of pipe fittings is a critical process in pressure vessels, pipeline engineering, and other fields. Welding quality, especially the straightness, penetration uniformity, and aesthetic appearance of the weld, directly determines the structural strength and service life of the final product. To obtain high-quality welds, a core prerequisite is stable and precise positioning of the pipe fittings, ensuring that they do not shift during welding and that the straight seam to be welded is precisely aligned with the working path of the welding mechanism (such as a traveling welding trolley).

[0003] In existing straight seam welding equipment for pipe fittings, one method that provides excellent positioning stability is to use an internal support mandrel (or positioning rod). Specifically, a horizontal positioning rod is inserted into the pipe fitting; the fitting naturally sags under gravity and is supported by the positioning rod, thus stably exposing the straight seam at its top, making it ideal for welding operations. This method avoids deformation or interference with the welding path that external clamps may cause, making it an ideal pipe fitting positioning solution.

[0004] However, the aforementioned straight seam welding device for pipe fittings suffers from problems such as low automation in the pipe fitting loading and positioning process, high labor intensity, complex operation, and potential safety hazards. Specifically, it requires manual operation to align the pipe fitting axis with the positioning rod, allowing the positioning rod to "pass" into the pipe fitting. This is not only time-consuming and labor-intensive, but also prone to causing collisions between the pipe fitting and the positioning rod, damaging the equipment, and even leading to safety accidents. Summary of the Invention

[0005] The purpose of this utility model is to provide a pipe fitting processing device to solve the problems of low automation, high labor intensity, complex operation and safety hazards in the pipe fitting feeding and positioning process.

[0006] A pipe fitting processing device includes: a working mechanism; a pipe fitting positioning mechanism for carrying the pipe fitting and aligning the area of ​​the pipe fitting to be processed with the working mechanism; a lifting mechanism connected to the pipe fitting positioning mechanism for driving the pipe fitting positioning mechanism to move up and down between a loading / unloading position and a working position; and a feeding mechanism arranged on one side of the lifting mechanism. When the pipe fitting positioning mechanism is in the loading / unloading position, the feeding mechanism is used to feed the pipe fitting into or out of the pipe fitting positioning mechanism along a first direction, and the arrangement of the feeding mechanism does not interfere with the lifting / unloading movement of the pipe fitting positioning mechanism towards the working position.

[0007] As an optimization and / or instantiation of the above-mentioned pipe fitting processing device, further: the working mechanism is a welding mechanism for welding the weld seam of the pipe fitting.

[0008] As an optimization and / or instantiation of the above-mentioned pipe fitting processing device, further: the welding mechanism is a straight seam welding mechanism, used for welding the straight seam of the pipe fitting.

[0009] As an optimization and / or instantiation of the above-mentioned pipe fitting processing device, further: the pipe fitting positioning mechanism includes a positioning rod extending along the first direction, and the pipe fitting is sleeved on the positioning rod.

[0010] As an optimization and / or instantiation of the above-mentioned pipe fitting processing device, further: the positioning rod is horizontally positioned and the outer diameter of the positioning rod is smaller than the inner diameter of the pipe fitting, so that the pipe fitting hangs naturally on the positioning rod due to gravity.

[0011] As an optimization and / or instantiation of the above-mentioned pipe fitting processing device, further: the positioning rod is provided with a pipe fitting axial limiting structure, and when the pipe fitting is fed into the positioning rod by the feeding mechanism, the pipe fitting is axially limited by the pipe fitting axial limiting structure.

[0012] As an optimization and / or instantiation of the above-mentioned pipe fitting processing device, further: the lifting mechanism is arranged at one end of the positioning rod that is relatively far from the feeding mechanism, and includes a lifting mechanism for driving the pipe fitting positioning mechanism to perform vertical lifting and lowering movements, and a lifting guide mechanism for cooperating with the end guide of the positioning rod.

[0013] As an optimization and / or instantiation of the above-mentioned pipe fitting processing device, further: the feeding mechanism includes a feeding roller track formed by a plurality of support rollers.

[0014] As an optimization and / or instantiation of the above-mentioned pipe fitting processing device, further: the feeding roller conveyor includes a left roller conveyor and a right roller conveyor, and the support surface of the support roller of the left roller conveyor and the support surface of the support roller of the right roller conveyor form a V-shaped support surface for centering support of the pipe fitting.

[0015] As an optimization and / or instantiation of the above-mentioned pipe processing device, further: a pipe posture adjustment mechanism is provided at one end of the feeding roller conveyor away from the pipe positioning mechanism, which is used to adjust the pipe in a horizontal state on the feeding roller conveyor to a vertical state.

[0016] The beneficial effects of this utility model are as follows: By setting up a lifting mechanism, the pipe fitting positioning mechanism can be driven to move up and down between a low loading / unloading position and a high working position. When the pipe fitting positioning mechanism is in the loading / unloading position, the feeding mechanism can easily and automatically feed the pipe fitting into the pipe fitting positioning mechanism along the first direction, replacing the complex operation of manually loading and positioning the pipe fitting in the prior art. After the pipe fitting is loaded, the lifting mechanism then lifts it to the working position to cooperate with the working mechanism for processing. The entire process realizes the automation of pipe fitting loading and positioning, significantly improving production efficiency and reducing labor intensity; at the same time, since the arrangement of the feeding mechanism does not interfere with the lifting and lowering movement of the pipe fitting positioning mechanism to the working position, it ensures the smooth operation of the pipe fitting processing device, effectively avoids the risk of collision, and improves operational safety.

Detailed Implementation

[0022] The present invention will now be clearly and completely described in conjunction with the accompanying drawings. Those skilled in the art will be able to implement the present invention based on these descriptions.

[0023] The embodiments of the present invention described below are generally only some embodiments and not all embodiments. Based on these embodiments, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of patent protection.

[0024] The terms "comprising," "including," "having," and any variations thereof in this specification, the corresponding claims, and related sections are intended to cover non-exclusive inclusion. Other related terms and units can be reasonably interpreted based on the relevant content provided in this specification.

[0025] Please see Figure 1 , Figure 3 This utility model provides a pipe fitting processing device, which includes four core parts: a working mechanism 11, a pipe fitting positioning mechanism 12, a lifting mechanism 13, and a feeding mechanism 14.

[0026] In this embodiment, the working mechanism 11 is mounted on top of the pipe processing device via a frame and is used to process the positioned pipes. Specifically, the working mechanism 11 can be a welding mechanism, more specifically, a straight seam welding mechanism, such as a welding trolley that can move along a track in a first direction (i.e., the pipe axis), for automated welding of the straight seams of the pipes.

[0027] See also Figure 1 and Figure 3 The pipe positioning mechanism 12 is crucial for achieving precise pipe support. Specifically, the pipe positioning mechanism 12 includes a positioning rod 121 extending along the first direction. The positioning rod 121 is horizontally positioned, and its outer diameter is designed to be smaller than the inner diameter of the pipe to be processed. This design allows the pipe 20 to be smoothly fitted onto the positioning rod 121 and naturally suspended on the positioning rod 121 due to its own weight, thereby achieving stable and stress-free support and ensuring the stability of the working area (such as the weld seam) at its top. In order to achieve precise axial positioning after the feeding mechanism 14 feeds in the pipe 20, the positioning rod 121 is also provided with a pipe axial limiting structure (e.g., a fixed stop 122). When the pipe is fed into place, its end face abuts against the pipe axial limiting structure, thereby completing the axial limiting.

[0028] The lifting mechanism 13 is the mechanism that realizes the core function of this utility model. It is connected to the pipe positioning mechanism 12 and is used to drive the entire pipe positioning mechanism 12 (together with the pipes it carries) to move up and down between the low loading and unloading position and the high working position.

[0029] like Figure 1 and Figure 3As shown, the lifting mechanism 13 is preferably arranged at one end of the positioning rod 121 that is relatively far from the feeding mechanism 14. This arrangement allows for complete operating space for the feeding mechanism 14. Specifically, the lifting mechanism 13 may include a lifting mechanism (e.g., a first hydraulic cylinder 131, an electric push rod, or a lead screw module) for driving the pipe positioning mechanism 12 to perform vertical lifting movements, and a lifting guide mechanism (e.g., a linear guide slider pair 132) for guiding and engaging with the end of the positioning rod 121, to ensure the smoothness and accuracy of the lifting process.

[0030] See Figure 1 and Figure 2 The feeding mechanism 14 is arranged on one side of the lifting mechanism 13. Its core function is that when the pipe positioning mechanism 12 is in the low loading and unloading position, the feeding mechanism 14 can conveniently feed the pipe into or out of the pipe positioning mechanism 12 along the first direction.

[0031] A key structural feature of the feeding mechanism 14 is that the overall arrangement of the feeding mechanism 14 (including its height and the space it occupies) does not interfere with the lifting and lowering movement of the pipe positioning mechanism 12 from the loading and unloading position to the higher working position.

[0032] In this embodiment, the feeding mechanism 14 specifically includes a feeding roller track 141 formed by multiple support rollers. In order to effectively center and support the cylindrical pipe during the conveying process and prevent it from rolling off course, the feeding roller track 141 preferably includes a left roller track 141a and a right roller track 141b. The support surfaces of the support rollers of the left roller track 141a and the support surfaces of the support rollers of the right roller track 141b together form a V-shaped support surface, so that the pipe can be stably conveyed while sitting in the V-shaped groove.

[0033] Furthermore, to further improve the level of automation, a pipe posture adjustment mechanism 15 can be added to one end of the feeding roller conveyor 141 away from the pipe positioning mechanism 12. This pipe posture adjustment mechanism 15 includes tilting arms 151 located on both sides of the feeding roller conveyor 141, and a crank mechanism for driving the tilting arms 151 to tilt (this crank mechanism can convert the reciprocating linear motion generated by a second hydraulic cylinder 152 or a pneumatic cylinder into the rotational motion of the tilting arms 151), thereby adjusting the pipes that are horizontal on the feeding roller conveyor 141 to a vertical position, avoiding manual tilting. The vertically adjusted pipes can be removed from the feeding roller conveyor 141 and placed directly vertically on the ground.

[0034] The workflow of the pipe fitting processing device in this embodiment is as follows: 1) In the initial state, the lifting mechanism 13 drives the pipe fitting positioning mechanism 12 (i.e., positioning rod 121) to descend to the low loading and unloading position. The height of this position matches the conveying height of the feeding mechanism 14 (i.e., feeding roller conveyor 141). 2) The feeding mechanism 14 starts and then conveys the pipe fitting along the first direction through the feeding roller conveyor 141, so that it can be smoothly fitted onto the low positioning rod 121 until its end touches the axial limiting structure (stop block 122) of the pipe fitting, completing the loading and positioning. 3) The lifting mechanism 13 starts and drives the pipe fitting positioning mechanism 12 carrying the pipe fitting to be lifted vertically upward to the preset high working position. At this position, the area to be worked on the pipe fitting is precisely aligned with the working mechanism 11 above. Since the feeding mechanism 14 is arranged on one side and at a low height, it does not affect this lifting process at all. 4) The working mechanism 11 (such as a straight seam welding mechanism) starts to work and performs welding processing on the pipe fitting. 5) After the operation is completed, the lifting mechanism 13 drives the pipe positioning mechanism 12 to descend and return to the low loading and unloading position. 6) The processed pipe is removed from the positioning rod 121 by the feeding mechanism 14. If there is a pipe posture adjustment mechanism 15, the pipe that is in a horizontal state on the feeding roller 141 is adjusted to a vertical state, and then the pipe is removed from the feeding roller 141 to complete one work cycle.

[0035] By introducing the lifting mechanism 13, two different height planes, the loading and unloading position and the working position, are cleverly set up, thereby decoupling the feeding mechanism 14 and the working mechanism 11 in space. This solves the structural contradiction between automated feeding and interference-free operation in the prior art and realizes the automation, efficiency and safety of the entire pipe fitting processing process.

[0036] The foregoing has described the relevant content of this utility model. Those skilled in the art will be able to implement this utility model based on these descriptions. All other embodiments obtained by those skilled in the art based on the foregoing content of this specification without inventive effort should fall within the scope of this utility model.
