Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a pipe welding device. Background Art

[0002] Prior art CN108215216 A discloses a hot melt angle welding machine and a control method, comprising a first frame, on which is provided a first clamp for clamping a first pipe and a second clamp for clamping a second pipe, the first clamp and the second clamp being able to move linearly along the first frame, approaching or moving away from each other; and further comprising a second frame, on which is provided a milling cutter component, a hot plate component, a milling cutter driving device for driving the milling cutter component to move from a first position to a second position to mill the first pipe and the second pipe, and a hot plate driving device for driving the hot plate component to move from the first position to the second position to hot-seal the first pipe and the second pipe.

[0003] There are some problems with the welding machine of the prior art: the first frame and the second frame are relatively fixed, which results in the relative position of the milling cutter component and the hot plate component in the extension direction of the first frame being unadjustable. In some cases, the pipe to be welded is a fixed pipe of the user and is inconvenient to move, and the position between the milling cutter component and the hot plate component and the pipe end is not appropriate, resulting in the milling cutter component not being able to smoothly cut the pipe end or the hot plate component not being able to synchronously heat the pipe ends on both sides, that is, the applicable scenarios of the welding machine are relatively narrow. Moreover, the milling cutter component and the hot plate component need to adjust their positions along the extension direction of the second frame respectively through the milling cutter drive device and the hot plate drive device, and the two adjust their respective positions along the extension direction of the second frame respectively through a drive device. The drive device has many components and a complex structure.

[0004] Therefore, it is necessary to improve the pipe welding equipment to solve the problems in the prior art that the milling cutter component and the hot plate component cannot be adjusted in the extension direction of the first frame, resulting in a narrow application scenario of the welding machine, and the structure of the position adjustment mechanism of the milling cutter component and the hot plate component along the extension direction of the second frame is too complicated. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the purpose of the present utility model is to provide a pipe welding device, which solves the problem in the existing technology that the cutting part and the heating part cannot be adjusted in the extension direction of the first frame, resulting in a narrow application scenario of the welding machine, and simplifies the structure of the position adjustment mechanism of the cutting part and the heating part along the extension direction of the second frame.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A pipe welding device comprises a chassis, and a first clamp group, a second clamp group, a heating component and a flattening component mounted on the top of the chassis;

[0008] The first clamp group and the second clamp group are used to clamp two pipes to be welded respectively, and at least one of the two clamp groups can move relative to the chassis along a first direction to move the ends of the two pipes to be welded closer to or farther away from each other;

[0009] The machine also includes a movable base plate movable along a first direction, the movable base plate being located on the top of the chassis, and the heating assembly and the flattening assembly being synchronously moved relative to the chassis along the first direction via the movable base plate;

[0010] It also includes a clamping seat movable along the second direction, and a first clamping member and a second clamping member respectively provided at the bottom of the flattening assembly and the bottom of the heating assembly;

[0011] When the first clamping piece is clamped with the clamping seat, the flattening component can move along the second direction to extend between the first clamp group and the second clamp group or move out from between the first clamp group and the second clamp group. When the second clamping piece is clamped with the clamping seat, the heating component can move along the second direction to extend between the first clamp group and the second clamp group or move out from between the first clamp group and the second clamp group.

[0012] In the pipe welding equipment of the present invention, the heating component and the flattening component can move in the first direction and the second direction, so that the relative position relationship between the heating component and the flattening component and the end of the pipe to be welded can be finely adjusted when the first clamping group and the second clamping group remain stationary after the pipe is clamped; the movable base plate drives the heating component and the flattening component to move synchronously in the first direction, and the flattening component and the heating component correspond to the end of the pipe to be welded in turn, meeting the process arrangement of first planing the pipe end and then heating the pipe end; at the same time, the clamping seat is respectively engaged with the first clamping member and the second clamping member, so that the same component can respectively control the position of the flattening component and the heating component in the second direction, approaching or moving away from the end of the pipe to be welded, so as to realize planing or heating of the end of the pipe to be welded, thereby simplifying the driving structure of the heating component and the flattening component in the second direction, which not only makes the volume of the driving structure smaller, but also makes the operation simple, convenient, labor-saving, and highly automated, thereby improving the working efficiency of the pipe welding equipment, the displacement of the flattening component and the heating component is precise, and accurately matches the end of the pipe to be welded, with high planing accuracy and heating accuracy, effectively improving the welding quality.

[0013] Preferably, the leveling assembly has a first mounting seat located at the bottom thereof, and the heating assembly has a second mounting seat located at the bottom thereof;

[0014] The movable substrate is provided with a first through-groove corresponding to the leveling assembly and a second through-groove corresponding to the heating assembly, and the first through-groove and the second through-groove extend along the second direction;

[0015] A first connecting plate fixed to the first mounting seat passes through the first through slot, and the first clamping member is fixed to the bottom of the first connecting plate and can be movably engaged with the clamping seat;

[0016] The second connecting plate fixed to the second mounting seat passes through the second through slot, and the second clamping piece is fixed to the bottom of the second connecting plate and can be movably clamped with the clamping seat.

[0017] The first mounting base is fixed to the bottom of the leveling component, the first clamping member is fixed to the bottom of the first mounting base through the first connecting plate, the second mounting base is fixed to the bottom of the heating component, the second clamping member is fixed to the bottom of the second mounting base through the second connecting plate, the first connecting plate and the second connecting plate respectively pass through the first through-slot and the second through-slot, the leveling component, the first mounting base, the first connecting plate, and the first clamping member are arranged vertically, and the heating component, the second mounting base, the second connecting plate, and the second clamping member are arranged vertically, thereby reducing the footprint of the above components and improving space utilization. The functions of the first through-slot and the second through-slot are as follows: on the one hand, the first through-slot allows the first connecting plate to pass through and to be movably engaged with the clamping member by the first clamping member located at the bottom of the first connecting plate; similarly, the second through-slot allows the second connecting plate to pass through and to be movably engaged with the clamping member by the second clamping member located at the bottom of the second connecting plate, that is, the clamping member is also located below the movable base, forming an up-down arrangement with the movable base, thereby improving space utilization; on the other hand, the first through-slot and the second through-slot can also guide the leveling component and the heating component to move along the second direction, thereby improving the movement accuracy of the leveling component and the heating component in the second direction.

[0018] Preferably, the movable base plate is provided with a second slide rail, extending along the second direction. The first mounting base includes a first body and a first slider, the first slider being fixed to the bottom surface of the first body, the first slider being slidably connected to the second slide rail, and the first connecting plate being fixed to the first body. The second slide rail cooperates with the first through-slot to further limit the movement accuracy of the leveling assembly in the second direction. The slidable cooperation between the first slider and the second slide rail also improves the smoothness of the leveling assembly during movement in the second direction, thereby optimizing the precision of the leveling assembly in planing the end of the pipe to be welded.

[0019] Preferably, the movable base plate is provided with a third slide rail, the third slide rail extending along the second direction, the second mounting seat including a second body and a second slider, the second slider being fixed to the bottom surface of the second body, the second slider being slidably connected to the third slide rail, and the second connecting plate being fixed to the second body. The third slide rail cooperates with the second through-slot, thereby limiting the movement accuracy of the heating assembly in the second direction. The sliding cooperation between the second slider and the second slide rail also improves the stability of the heating assembly when moving and stationary in the second direction, so that when the heating assembly is placed between the first clamp group and the second clamp group, the distance from the end of the pipe to be welded is accurate and controllable, thereby achieving precise heating of the pipe end and optimizing the welding effect.

[0020] Preferably, the pipe welding device further comprises a second motor for driving the clamping base to move along the second direction, the second motor being located inside the chassis, the top of the chassis having a top plate, a gap being defined between the top plate and the movable base plate, the first clamping member and the second clamping member being located in the gap;

[0021] A third through slot is provided on the top plate, and the third through slot extends along the second direction. The card holder is located inside the chassis and is connected to the output end of the second motor. The top end of the card holder passes through the third through slot and is placed in the gap.

[0022] When the movable substrate moves along the first direction so that the first through slot is aligned with the third through slot, the clamping seat is movably engaged with the first clamping member;

[0023] When the movable base plate moves along the first direction so that the second through slot is aligned with the third through slot, the clamping seat is movably clamped with the second clamping member.

[0024] The second motor is disposed inside the chassis, while the movable base is located above the top plate. This arrangement of the second motor can reduce the structure above the chassis top plate, fully utilizing the space inside the chassis. It can also reduce the height of the movable base plate and the heating and leveling components thereon, thereby reducing the height of the entire pipe welding apparatus. The top plate itself can improve the installation stability of the movable base plate. In particular, when the movable base plate supports a heavier heating and leveling component, the downward force exerted on the chassis by the movable base plate is greater. The top plate can effectively distribute the force exerted on the chassis by the movable base plate, thereby ensuring the stability of the overall structure. A gap is provided between the top plate and the movable base plate, thereby reducing friction when the movable base plate moves relative to the top plate. Furthermore, the top ends of the first and second clamping members and the base can be disposed within the gap, utilizing the gap space and facilitating the installation of the first and second clamping members. The majority of the second motor and base plate are disposed inside the chassis, below the top plate. A third through-slot on the top plate allows the top end of the base plate to pass through, allowing the base plate to engage with the first or second clamping member and restricting the direction of movement of the base plate, ensuring that it moves in the second direction.

[0025] Preferably, the top plate is further provided with a first limiting member and a second limiting member, and the first limiting member and the second limiting member are respectively provided on both sides of the third through groove along the first direction;

[0026] The first limiting member includes a first limiting groove and a first limiting block. The first limiting groove is opened along the first direction and enables the first clamping member to move therein along the first direction. The first limiting block is located on a side of the first limiting groove away from the third through groove.

[0027] The second limiting member includes a second limiting groove and a second limiting block. The second limiting groove is opened along the first direction, enabling the second clamping member to move along the first direction therein. The second limiting block is located on a side of the second limiting groove away from the third through groove.

[0028] One side of the first limiting groove is open and engages with the third through-groove. When the holder moves to align with the first limiting groove, the first clamping member in the first limiting groove can accurately move to the holder and engage therewith. Thus, only the position of the holder in the second direction needs to be controlled to achieve accurate docking of the first clamping member and the holder, simplifying the control mode and facilitating operation. The first limiting block functions to limit the movement distance of the first clamping member and the corresponding leveling assembly in the first direction, thereby preventing the leveling assembly from moving too far. Similarly, one side of the second limiting groove is open and engages with the third through-groove. When the holder moves to align with the second limiting groove, the second clamping member in the second limiting groove can accurately move to the holder and engage therewith. Thus, only the position of the holder in the second direction needs to be controlled to achieve accurate docking of the second clamping member and the holder, thereby simplifying the control mode and facilitating operation. The second limiting block functions to limit the movement distance of the second clamping member and the corresponding heating assembly in the first direction, thereby preventing the heating assembly from moving too far.

[0029] Preferably, the top plate further includes a transfer member.

[0030] In the first direction, the transfer member is located on at least one side of the third through slot and relatively close to the first clamp group or the second clamp group;

[0031] In the second direction, the transfer member is located on one end side of the third through slot close to the first clamp group and the second clamp group;

[0032] The transfer member is provided with a transfer groove extending along the first direction for movably engaging with the second engaging member.

[0033] The function of the transfer piece is that, in some specific usage scenarios, the heating component needs to be closer to the end of one of the pipes to be welded for preheating to meet special welding requirements. The transfer piece is movably connected with the second clamping piece of the heating component in this state, which can improve the stability of the heating component in the first direction when working, maintain the distance from the end of the pipe to be welded, and thus improve the heating effect; adjusting the position of the heating component in the first direction to adapt to the pipe to be welded can meet some welding conditions of pipes to be welded that are inconvenient to move, and has a wider and more flexible application scenario. Based on this, the transfer member is arranged on at least one side of the third through slot in the first direction. Regardless of whether it is the pipe to be welded clamped by the first clamp group or the pipe to be welded clamped by the second clamp group, heating can be achieved at a closer distance, and one of the pipes can be preheated in advance; at the same time, the transfer member is arranged on one end side of the third through slot closer to the first clamp group and the second clamp group in the second direction, that is, after the heating component is moved between the first clamp group and the second clamp group under the drive of the clamping seat, the distance from the pipe to be welded in the first direction is adjusted. There is no need to adjust the position of the clamping seat and the third through slot, which takes into account both daily heating needs and specific heating needs, has more diverse applicable scenarios, and is easy to operate without changing the structure of the mobile base and the clamping seat.

[0034] Preferably, the top of the card seat is provided with a locking groove extending along the first direction, and the first locking part or the second locking part moves into or out of the locking groove along the first direction and abuts against the side wall of the locking groove; the locking method of the card seat and the first locking part or the second locking part is simplified, and the first locking part and the second locking part only need to move along the first direction to achieve movable locking with the card seat, without the need for additional matching structure.

[0035] Preferably, the first clamping member and the second clamping member each include at least one roller, and the side wall of the roller is movably abutted against the side wall of the clamping groove, so that when the first clamping member or the second clamping member is movably clamped with the clamping groove on the base, the friction force is smaller and the operation is more labor-saving; at the same time, the roller can also cooperate with the clamping groove to play a certain guiding role when the first clamping member or the second clamping member is movably clamped with the base, and even if there is a slight misalignment between the clamping groove on the base and the roller, the roller can apply an adjustment force in the second direction to the clamping groove, fine-tune the position of the base in the second direction, and make the roller more easily clamped into the clamping groove.

[0036] Preferably, the first direction and the second direction are perpendicular, the first clamp group and the second clamp group are arranged on the mounting plane of the chassis, the top of the chassis has a top plate, the top plate is tilted relative to the mounting plane, and the side away from the mounting plane is lower than the side close to the mounting plane; the movable substrate is arranged parallel to the top plate, and the heating component and the leveling component are tilted relative to the mounting plane based on the movable substrate.

[0037] As a result, the vertical height of the leveling assembly and the heating assembly is reduced, and the overall height of the pipe welding equipment is also reduced. When a tee or other components are connected to the pipe to be welded, the leveling assembly and the heating assembly can avoid interference with the tee or other components. In addition, since the movable base plate is arranged at an angle, when the leveling assembly cuts the end face of the pipe to be welded, the debris formed can fall along the inclined surface and will not accumulate on the movable base plate to affect the movement of the movable base plate.

[0038] Preferably, a first slide rail extending along the first direction is provided on the top of the chassis, and the movable substrate slides in cooperation with the first slide rail; the first slide rail ensures smooth sliding of the movable substrate in the first direction, thereby realizing precise displacement of the heating component and the leveling component in the first direction.

[0039] Preferably, a first motor is fixed inside the chassis, a rack extending along the first direction is fixed to the bottom of the movable base plate, and a gear is provided at the output end of the first motor, and the gear is engaged with the rack for transmission to drive the movable base plate to move along the first direction; the movement of the movable base plate in the first direction is controlled by the motor and gear transmission, so as to achieve precise control of the positions of the heating component and the leveling component in the first direction, so that the leveling component and the heating component can accurately correspond to the end of the pipe to be welded, meeting the planing requirements and heating requirements.

[0040] In summary, compared with the prior art, the present invention has at least the following beneficial effects:

[0041] In the pipe welding equipment of the present invention, the heating component and the flattening component can move in the first direction and the second direction, so that when the first clamp group and the second clamp group remain stationary after the pipe is clamped, the positional relationship between the heating component and the flattening component and the end of the pipe to be welded can be finely adjusted; the movable base plate drives the heating component and the flattening component to move synchronously in the first direction, and the flattening component and the heating component correspond to the end of the pipe to be welded in turn, meeting the process arrangement of first planing the pipe end and then heating the pipe end; at the same time, the clamping seat is respectively engaged with the first clamping piece and the second clamping piece, so that the same component can respectively control the position of the flattening component and the heating component in the second direction, approaching or moving away from the end of the pipe to be welded, so as to realize planing or heating of the end of the pipe to be welded, thereby simplifying the driving structure of the heating component and the flattening component in the second direction, not only making the volume of the driving structure smaller, but also making the operation simple, convenient, labor-saving, and highly automated, thereby improving the working efficiency of the pipe welding equipment, the displacement of the flattening component and the heating component is precise, accurately matching the end of the pipe to be welded, the planing accuracy and the heating accuracy are high, and the welding quality is effectively improved.

[0058] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0059] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0060] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0061] As attached Figure 1As shown, the pipe welding equipment of the embodiment of the present invention includes a chassis 10, and a first clamp group 20, a second clamp group 30, a heating component 40 and a flattening component 50 installed on the top of the chassis 10. The chassis 10 is used to place electrical appliances and control equipment, and provides a mounting platform for components such as the heating component 40, the flattening component 50, and the clamp group; the first clamp group 20 and the second clamp group 30 are used to clamp two pipes to be welded, respectively, and at least one of them can move relative to the chassis 10 along a first direction to bring the ends of the two pipes to be welded closer or farther away; the axial direction of the clamp group refers to the line connecting the clamping centers of the clamps in each clamp group, and its purpose is to maximize the area of ​​the ends of the pipes to be welded clamped by each clamp group, thereby maximizing the welding area to ensure welding strength; the spacing between the clamp groups is adjustable, that is, at least one clamp group can be movable in the first direction. Generally speaking, the movement direction of each clamp group is the first direction, which is substantially coincident with the axial direction, but it is not ruled out that the clamp group is offset by a certain angle relative to the chassis 10 so that the first direction has an angle with the axial direction of the clamp group.

[0062] In the pipe welding equipment, the flattening assembly 50 is used to cut and correct the end face of the pipe to be welded to improve the flatness and smoothness of the end face. The flattening assembly 50 can be made of conventional equipment such as a planer, a turning tool, or a grinding tool. When the pipe welding equipment is working, the flattening assembly 50 is generally used to cut the end face of the pipe to be welded to improve the flatness, and then the end face of the pipe to be welded is heated by the heating assembly 40. After the end face is melted, the first clamp group 20 and the second clamp group 30 are brought closer, and the end faces of the two pipe fittings are abutted and welded together.

[0063] Based on the above process, the heating component 40 and the flattening component 50 in the pipe welding equipment generally do not work at the same time. Therefore, the pipe welding equipment of this embodiment also includes a movable substrate 60 that can move along the first direction. The movable substrate 60 is located on the top of the chassis 10, and the heating component 40 and the flattening component 50 are arranged side by side on the movable substrate 60, and are synchronously moved relative to the chassis 10 along the first direction through the movable substrate 60, so that the heating component 40 or the flattening component 50 is moved in turn along the first direction to the position corresponding to the end surface of the pipe to be welded. The position of the heating component 40 and the flattening component 50 in the first direction can be easily controlled by a movable substrate 60. The structure is simple and the operation is convenient, which meets the process arrangement of first planing the pipe end and then heating the pipe end.

[0064] Based on the above process, the heating component 40 and the flattening component 50 both need to approach and move away from the first clamp group 20 and the second clamp group 30, thereby achieving heating and cutting of the end face of the pipe to be welded. Therefore, the pipe welding equipment of this embodiment also includes a holder 72 that can be moved along the second direction and a first clamping member 73 and a second clamping member 74 respectively arranged at the bottom of the flattening component 50 and the heating component 40. When the first clamping member 73 is clamped with the holder 72, the flattening component 50 can be moved along the second direction to extend into or move out from between the first clamp group 20 and the second clamp group 30. When the second clamping member 74 is clamped with the holder 72, the heating component 40 can be moved along the second direction to extend into the first clamp group 20 and the second clamp group 30. The clamp group 20 is moved between the second clamp group 30 or out from between the first clamp group 20 and the second clamp group 30; thereby, the same component, i.e., the holder, can be used to control the positions of the flattening component 50 and the heating component 40 in the second direction respectively, close to or away from the end of the pipe to be welded, and the end of the pipe to be welded is planed or heated, which simplifies the driving structure of the heating component 40 and the flattening component 50 in the second direction, not only making the volume of the driving structure smaller, but also making the operation simple, convenient, labor-saving, and highly automated, thereby improving the working efficiency of the pipe welding equipment, and the displacement of the flattening component 50 and the heating component 40 is precise, accurately matching the end of the pipe to be welded, with high planing accuracy and heating accuracy, effectively improving the welding quality.

[0065] The movement of the movable substrate 60 in the first direction can be achieved manually or by motor drive, and the movement of the leveling component 50 and the heating component 40 in the second direction can also be achieved manually or by motor drive.

[0066] Preferably, in this embodiment, the first direction and the second direction are perpendicular to each other. Figure 3 The X direction shown represents the first direction. In the same horizontal plane, the direction perpendicular to the X direction is similar to Figure 1 The Y direction in the figure is defined as the second direction; the first and second directions can be understood as the left-right and front-facing directions in the horizontal plane. Accordingly, movement of the movable substrate 60 in the first direction adjusts the left-right positions of the leveling assembly 50 and the heating assembly 40 in the horizontal plane, while movement of the leveling assembly 50 and the heating assembly 40 in the second direction adjusts their respective front-back positions in the horizontal plane. The first and second directions are perpendicular, facilitating calculation of the positions of the heating assembly 40 and the leveling assembly 50 in the coordinate system, enabling precise control.

[0067] In other embodiments, the first and second directions may not be perpendicular but may be at an angle to each other, i.e., there may be some offset from the horizontal coordinate system. In this case, the offset must be considered when calculating the positions of the heating assembly 40 and the leveling assembly 50. Although this requires more calculations, precise control can still be achieved. For ease of understanding, the following embodiments are described based on the assumption that the first and second directions are perpendicular to each other.

[0068] like Figure 1 As shown, a first slide rail 13 extending along a first direction is provided on the top of the chassis 10, and the movable base plate 60 slides in cooperation with the first slide rail 13. Specifically, a slider adapted to the first slide rail 13 is fixed to the bottom of the movable base plate 60, and the slider is mounted on the outer periphery of the first slide rail 13 to achieve smooth movement of the movable base plate 60 along the first slide rail 13, that is, to achieve precise displacement of the heating component 40 and the leveling component 50 in the first direction.

[0069] The first slide rail 13 can be fixedly connected to the top structure of the chassis 10 frame, and the number is not limited to one, to ensure the stable installation of the movable base plate 60. Preferably, in this embodiment, a top plate 11 is provided on the top of the chassis 10, and the first slide rail 13 is fixedly set on the top plate 11. The top plate 11 is fixedly connected to the frame structure of the chassis 10. The top plate 11 itself can improve the installation stability of the movable base plate 60. In particular, after receiving the heavier heating component 40 and the leveling component 50, the downward force applied by the movable base plate 60 to the chassis 10 is relatively large. The top plate 11 can effectively share the force applied by the movable base plate 60 to the chassis 10, ensuring the stability of the overall structure. Since the first slide rail 13 is provided on the top plate 11, a gap 66 is formed between the movable base plate 60 and the top plate 11. The gap 66 can also reduce the friction when the movable base plate 60 moves relative to the top plate 11, making the movement of the movable base plate 60 and the heating component 40 and the leveling component 50 thereon more labor-saving.

[0070] like Figure 4As shown, a rack 61 extending in a first direction is fixed to the bottom of the movable base 60. The rack 61 is arranged side by side with the first slide rail 13. The difference is that the rack 61 is fixedly connected to the movable base 60, while the first slide rail 13 is fixedly connected to the top or top plate 11 of the chassis 10. A first motor 14 is fixed inside the chassis 10. The output end of the first motor 14 is provided with a gear 141. The gear 141 meshes with the rack 61 to drive the movable base 60 in the first direction. The first slide rail 13 restricts the position of the movable base 60 so that it can only move in the first direction. The movement of the movable base 60 in the first direction is then controlled by the motor and gear 141, achieving precise control of the position of the heating assembly 40 and the flattening assembly 50 in the first direction, so that the flattening assembly 50 and the heating assembly 40 can accurately align with the end of the pipe to be welded, meeting the planing and heating requirements. Similarly, the rack 61 and gear 141 are located in the gap 66 between the top plate 11 and the movable base 60, making the structure more compact and improving space utilization.

[0071] like Figure 2 As shown, the holder 72 is positioned below the movable base 60, avoiding occupying space on the movable base 60. This allows the holder 72 to be vertically distributed with the movable base 60 and the heating assembly 40 and leveling assembly 50 thereon, thereby reducing the footprint and improving space utilization. More preferably, a portion of the holder 72 can be positioned below the top plate 11 of the chassis 10. This protects the motor connected to the holder 72 or the movable base 60 while also reducing the height of the heating assembly 40 and leveling assembly 50.

[0072] More specifically, in order to realize the movable connection between the heating component 40 and the leveling component 50 and the card holder 72, as shown in FIG. Figure 3 and Figure 4 As shown, the leveling component 50 has a first mounting seat 51 located at the bottom thereof, the heating component 40 has a second mounting seat 41 located at the bottom thereof, and the movable substrate 60 is provided with a first through-groove 62 corresponding to the leveling component 50 and a second through-groove 63 corresponding to the heating component 40. The first through-groove 62 and the second through-groove 63 extend along the second direction, so that the heating component 40 and the leveling component 50 will not deviate when moving in the second direction, thereby ensuring accuracy; the first connecting plate 52 fixed to the first mounting seat 51 passes through the first through-groove 62, and the first clamping member 73 is fixed to the bottom surface of the first connecting plate 52, and can be movably clamped with the clamping seat 72; the second connecting plate 42 fixed to the second mounting seat 41 passes through the second through-groove 63, and the second clamping member 74 is fixed to the bottom surface of the second connecting plate 42, and can be movably clamped with the clamping seat 72; so that the upper and lower distribution of the movable substrate 60 and the clamping seat 72 can be realized.

[0073] like Figure 2As shown, the movable base plate 60 is provided with a second slide rail 64 extending in the second direction. The first mounting base 51 includes a first body 511 and a first slider 512. The first slider 512 is fixed to the bottom surface of the first body 511 and is slidably connected to the second slide rail 64. The first connecting plate 52 is fixed to the first body 511. The second slide rail 64 cooperates with the first through-slot 62 to further limit the movement accuracy of the leveling assembly 50 in the second direction. The sliding cooperation between the first slider 512 and the second slide rail 64 also improves the smoothness of the leveling assembly 50 during movement in the second direction, thereby optimizing the planing accuracy of the end of the pipe to be welded by the leveling assembly 50.

[0074] Since the leveling assembly 50 is large in size and heavy in weight, two parallel second slide rails 64 are provided on the movable base plate 60, and the first mounting seat 51 includes two or more first sliders 512, thereby improving the stability of the leveling assembly 50 on the second slide rails 64. Figure 3 As shown, the first connecting plate 52 fixed to the first mounting seat 51 extends downward from between the two second slide rails 64 and then passes through the first through slot 62 .

[0075] like Figure 4 and Figure 5 As shown, the movable base plate 60 is provided with a third slide rail 65, which extends along the second direction. The second mounting base 41 includes a second body 411 and a second slider 412. The second slider 412 is fixed to the bottom surface of the second body 411. The second slider 412 is slidably connected to the third slide rail 65, and the second connecting plate 42 is fixed to the second body 411. The third slide rail 65 cooperates with the second through-slot 63, thereby limiting the movement accuracy of the heating assembly 40 in the second direction. The sliding cooperation between the second slider 412 and the second slide rail 64 also improves the stability of the heating assembly 40 when moving and stationary in the second direction. When the heating assembly 40 is placed between the first clamp group 20 and the second clamp group 30, the distance between the heating assembly 40 and the end of the pipe to be welded is accurate and controllable, thereby achieving precise heating of the pipe end and optimizing the welding effect.

[0076] like Figure 5 and Figure 6As shown, the second motor 71 is located inside the chassis 10. The second motor 71 can be a linear motor, and the holder 72 is connected to the output end of the linear motor. Specifically, the second motor 71 can be fixedly connected to the lower surface of the top plate 11 or the internal frame structure of the chassis 10. The second motor 71 is arranged in this way. The structure above the top plate 11 of the chassis 10 can be reduced, and the space inside the chassis 10 can be fully utilized. It can also reduce the height of the movable substrate 60 and the heating component 40 and the leveling component 50 thereon, that is, the height of the entire pipe welding equipment is reduced; a connecting block 76 is provided on the output end of the linear motor, and the lower half of the holder 72 is fixed to the connecting block 76 by screws, so that the holder 72 can move in the second direction under the drive of the linear motor.

[0077] The movable base plate 60 and the second motor 71 are respectively located on the upper and lower sides of the top plate 11. Figure 6 As shown, a third through slot 111 is provided on the top plate 11, and the third through slot 111 extends along the second direction. The holder 72 is partially located inside the chassis 10 and is connected to the driving end of the second motor 71. The top end of the holder 72 passes through the third through slot 111 and is placed in the gap 66. When the holder 72 moves along the second direction under the action of the second motor 71, the third through slot 111 limits the holder 72 to prevent it from shifting.

[0078] Most of the holder 72 is located inside the chassis 10. During installation, the second motor 71 and the holder 72 can be connected first and set inside the chassis 10, and then the top plate 11 is covered so that the top of the holder 72 is exposed from the top plate 11 and placed in the gap 66. At the same time, the first clip 73 and the second clip 74 are also located in the gap 66, and there is no need to pass through the top plate 11 to extend into the interior of the chassis 10. The movable substrate 60 and the heating component 40 and the leveling component 50 thereon can be installed independently relative to the second motor 71 and the holder 72, reducing the difficulty of installation.

[0079] like Figure 3 and Figure 7 As shown, in order to facilitate the first clamping member 73 and the second clamping member 74 to be clamped into the clamping seat 72, the top of the clamping seat 72 is provided with a clamping groove 721 extending along the first direction. The first clamping member 73 or the second clamping member 74 moves into or out of the clamping groove 721 along the first direction and abuts against the side wall of the clamping groove 721; the clamping method of the clamping seat 72 and the first clamping member 73 or the second clamping member 74 is simplified. The first clamping member 73 and the second clamping member 74 only need to move along the first direction to achieve active clamping with the clamping seat 72, without the need for additional matching structure.

[0080] like Figure 7When the locking cam 721 is in the unlocking state, the locking cam 721 is unlocked, and the locking cam 721 is unlocked, so that the first locking cam 73 and the second locking cam 74 can be unlocked.

[0081] When the pipe welding equipment is in use, the movable base plate 60 moves along the first direction on the top plate 11. When the movable base plate 60 moves along the first direction so that the first through slot 62 is aligned with the third through slot 111, the clamping seat 72 is movably engaged with the first clamping member 73, and the second motor 71 drives the leveling component 50 to move along the second direction through the clamping seat 72, approaching or moving away from the first clamp group 20 and the second clamp group 30; the control system can control the moving distance of the movable base plate 60 through a program, and can also set a sensor to detect whether the first through slot 62 is aligned with the third through slot 111, such as a photoelectric switch or an infrared sensor light. The control system then determines that the leveling component 50 is moved into position based on the detection result of the sensor, and finally drives the leveling component 50 to move along the second direction through the second motor 71 and the clamping seat 72, thereby reducing the control difficulty and calculation amount, and ensuring the movement accuracy.

[0082] Similarly, the movable substrate 60 moves along the first direction on the top plate 11. When the movable substrate 60 moves along the first direction so that the second through groove 63 is aligned with the third through groove 111, the clamping seat 72 is movably engaged with the second clamping member 74, and the second motor 71 drives the heating component 40 to move along the second direction through the clamping seat 72, approaching or moving away from the first clamp group 20 and the second clamp group 30.

[0083] In addition to relying on program control to move the substrate 60 in the first direction, the movement of the substrate 60 can also be coordinated with the mechanical structure. Figure 7As shown, a first limiting member and a second limiting member are also provided on the top plate 11, and the first limiting member and the second limiting member are respectively arranged on both sides of the third through groove 111 along the first direction; the first limiting member includes a first limiting groove 112 and a first limiting block 113, and the first limiting groove 112 is opened along the first direction, so that the first clamping member 73 can move therein along the first direction, and the first limiting block 113 is located on the side of the first limiting groove 112 away from the third through groove 111; the second limiting member includes a second limiting groove 114 and a second limiting block 115, and the second limiting groove 114 is opened along the first direction, so that the second clamping member 74 can move therein along the first direction, and the second limiting block 115 is located on the side of the second limiting groove 114 away from the third through groove 111.

[0084] like Figure 7 As shown, one side of the first limiting groove 112 is open and docked with the third through groove 111. When the holder 72 moves to be aligned with the first limiting groove 112, the first clamping member 73 in the first limiting groove 112 can be accurately moved to the holder 72 and clamped therewith. Therefore, it is only necessary to control the position of the holder 72 in the second direction to achieve precise docking of the first clamping member 73 and the holder 72, which simplifies the control mode and facilitates operation. The function of the first limiting block 113 is to limit the moving distance of the first clamping member 73 and the corresponding leveling component 50 in the first direction to prevent the leveling component 50 from moving too far. Similarly, one side of the second limiting groove 114 is open and docked with the third through groove 111. When the holder 72 moves to align with the second limiting groove 114, the second clamping member 74 in the second limiting groove 114 can be accurately moved to the holder 72 and clamped therewith. Therefore, it is only necessary to control the position of the holder 72 in the second direction to achieve precise docking of the second clamping member 74 and the holder 72, which simplifies the control mode and facilitates operation. The function of the second limiting block 115 is to limit the moving distance of the second clamping member 74 and the corresponding heating component 40 in the first direction to prevent the heating component 40 from moving too far.

[0085] It should be noted that, preferably, the distance between the first limit block 113 and the second limit block 115 in the first direction is greater than the distance between the first clamping member 73 and the second clamping member 74 in the first direction. Therefore, the heating component 40 and the leveling component 50 have a wider range of movement in the first direction; and the first limit groove 112 and the second limit groove 114 are relative to each other in the second direction, and the holder 72 can be moved to the same position to align with the first limit groove 112 and the second limit groove 114 at the same time. Therefore, in some cases, the first clamping member 73 can slide into the second limit groove 114, or the second clamping member 74 can slide into the first limit groove 112; of course, in other embodiments, the positions of the first limit groove 112 and the second limit groove 114 in the second direction can be staggered, and the positions at which the holder 72 is aligned with the first limit groove 112 and the second limit groove 114 are different, which can be defined as position 1 and position 2 respectively and recorded in the control system to achieve precise movement of the holder 72.

[0086] Since the leveling assembly 50 and the heating assembly 40 are positioned between the first and second clamping sets 20 and 30 after approaching them, their movement space in the first direction is limited, and thus, the leveling assembly 50 and the heating assembly 40 are generally not controlled to move further in the first direction. However, in some special cases, the position of the leveling assembly 50 and the heating assembly 40 in the first direction can be appropriately adjusted after approaching the first and second clamping sets 20 and 30, so that the leveling assembly 50 and the heating assembly 40 are at a more suitable distance from the end of the pipe to be welded.

[0087] For example, in this embodiment, a transfer member 116 is further provided on the top plate 11. In the first direction, the transfer member 116 is located on at least one side of the third through-slot 111, relatively close to the first clamp group 20 or the second clamp group 30. In the second direction, the transfer member 116 is located on one end of the third through-slot 111, close to the first clamp group 20 and the second clamp group 30. The transfer member 116 is provided with a transfer groove 117 extending along the first direction for movably engaging with the second clamping member 74. The function of the transfer member 116 is to facilitate preheating in certain specific usage scenarios, where the heating assembly 40 needs to be positioned closer to the end of a pipe to be welded to meet special welding requirements. The movably engaging engagement of the transfer member 116 with the second clamping member 74 of the heating assembly 40 in this state can improve the stability of the heating assembly 40 in the first direction during operation, maintain a distance from the end of the pipe to be welded, and thus enhance the heating effect. Adjusting the position of the heating assembly 40 in the first direction to adapt to the pipe to be welded can meet welding conditions where the pipe to be welded is inconvenient to move, providing a wider and more flexible range of applications.

[0088] Based on this, the transfer member 116 is arranged on at least one side of the third through slot 111 in the first direction, and whether it is the pipe to be welded clamped by the first clamp group 20 or the pipe to be welded clamped by the second clamp group 30, heating can be achieved at a closer distance; at the same time, the transfer member 116 is arranged on one end side of the third through slot 111 closer to the first clamp group 20 and the second clamp group 30 in the second direction, that is, the heating component 40 is driven by the holder 72 to approach the first clamp group 20 and the second clamp group 30 and then adjusts the distance from the pipe to be welded. There is no need to adjust the position of the holder 72 and the third through slot 111, which takes into account both daily heating needs and specific heating needs, has more diverse applicable scenarios, and is easy to operate without changing the structure of the mobile base and the holder 72.

[0089] like Figure 1 and Figure 7 As shown, in this embodiment, the second clamp group 30 is fixed relative to the chassis 10 or can only be slightly adjusted in position, and is used to clamp the pipe to be welded that is inconvenient to move. The transfer member 116 is arranged on the right side of the third through slot 111 in the first direction, closer to the second clamp group 30. Without adjusting the second clamp group 30, the pipe to be welded clamped by the second clamp group 30 can also be preheated.

[0090] like Figure 1 As shown, the first clamp group 20 and the second clamp group 30 are arranged on the mounting plane 12 of the chassis 10, and the top of the chassis 10 has a top plate 11, which is inclined relative to the mounting plane 12, and its side away from the mounting plane 12 is lower than the side close to the mounting plane 12; the movable base plate 60 is arranged parallel to the top plate 11, and the heating component 40 and the leveling component 50 are inclined relative to the mounting plane 12 based on the movable base plate 60; thereby reducing the height of the leveling component 50 and the heating component 40 in the vertical direction, and also reducing the overall height of the pipe welding equipment. When a tee or other components are connected to the pipe to be welded, the leveling component 50 and the heating component 40 can avoid interference with the tee or other components; in addition, since the movable base plate 60 is inclined, when the leveling component 50 cuts the end face of the pipe to be welded, the debris formed can fall along the inclined surface and will not accumulate on the movable base plate 60 to affect the movement of the movable base plate 60.

[0091] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
