Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a processing apparatus for welding long shaft members. Background Technology

[0002] Long shaft members typically refer to rod-shaped components whose length is much greater than their cross-sectional dimensions, such as drive shafts and through-shaft tubes. They are widely used in machinery, construction, and bridges, and play an important role in engineering mechanics and structural design. Due to their length, these members generally require welding before use to join two members together. Welding long shaft members requires advanced technology. Because of their large length, poor rigidity, and susceptibility to deformation, multiple control measures are necessary to ensure welding quality. During the welding process, special attention must be paid to heat input control, deformation prevention, and ensuring joint strength and precision.

[0003] When butt-welding long shaft members, the end faces of the two sections are usually aligned before welding. However, due to the large length and relatively weak rigidity of the members, the overhanging ends are prone to slight downward tilting under their own weight. This causes the two butt-welding end faces to lose their coaxiality. This initial assembly deviation is amplified during the welding process, potentially leading to defects such as incomplete fusion, misalignment, and residual stress concentration. This affects the weld formation quality, reduces joint strength, and lowers the overall precision of the long shaft member, especially noticeable in the manufacturing of critical components such as high-precision drive shafts and large mechanical spindles. For example, existing patent CN222307840U discloses a method for welding long shaft members. The processing device, equipped with a mounting plate, a limiting bracket, chucks, a push rod, and a pneumatic cylinder, utilizes a pneumatic cylinder to pull the bottom of the pull rod to the right. This causes the upper end of the pull rod to pull the outer surface of the push ring, causing it to rotate under the constraint of the limiting plate. The rotation of the push ring then pushes the inner surface of the outer side of the push rod, causing it to rotate around the central column. During this process, the other end of the push rod pushes the chucks, moving them towards the inner surface of the insertion hole, ultimately clamping the long shaft located inside the insertion hole. This method can achieve the effect of welding long shafts, but it still cannot solve the problem of deviations occurring during the welding and assembly of long shaft components.

[0004] Therefore, how to provide a processing device for welding long shaft members is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] One object of the present invention is to provide a processing device for welding long shaft members. The processing device for welding long shaft members includes a processing plate, a rotating assembly on the processing plate, a clamping assembly at the output end of the rotating assembly, a support frame on the processing plate, a sliding assembly on the support frame, a driving assembly connected to the sliding assembly on the support frame, an adjusting assembly on the sliding assembly, a rotating assembly between the adjusting assembly and the driving assembly, a transmission assembly between the sliding assembly and the adjusting assembly, and a clamping assembly on the sliding assembly for clamping the end of the long shaft member. During adjustment, when the driving assembly is in a first state, the driving assembly controls the rotating assembly, the adjusting assembly, and the transmission assembly to move, forcing the clamping assembly to clamp the long shaft member; when the driving assembly is in a second state, the driving assembly controls the sliding assembly to move, forcing the clamping assembly to move, so that the long shaft member is axially aligned.

[0006] Preferably, the rotating assembly includes a rotary motor mounted on the processing plate, a support ring is provided on the processing plate, a rotating ring is connected to the support ring by a bearing, the output shaft of the rotary motor is connected to a drive gear, and a driven gear ring that meshes with the drive gear is fixedly sleeved on the rotating ring.

[0007] Preferably, the clamping assembly includes a hydraulic push rod disposed on the rotating ring, and the output end of the hydraulic push rod is provided with a plurality of clamping blocks. When the clamping blocks contact the long shaft member, the clamping function is realized.

[0008] Preferably, the sliding assembly includes a sliding frame slidably disposed on the support frame, the sliding frame being provided with a mounting ring, and a rotating ring being connected to the mounting ring by a bearing.

[0009] Preferably, the drive assembly includes an electric push rod hinged to the support frame, the output end of the electric push rod is hinged to a connecting rod, a rotating shaft is connected to the sliding frame by a bearing, and the connecting rod is fixedly sleeved on the rotating shaft.

[0010] Preferably, the adjusting assembly includes a connecting frame disposed on the sliding frame, a threaded rod is bearing-connected to the connecting frame, an adjusting block is threadedly connected to the threaded rod, the threaded rod is threaded through the adjusting block, and the adjusting block passes through the connecting frame.

[0011] Preferably, the rotating assembly includes a first rotating gear fixedly sleeved on the rotating shaft, and a second rotating gear fixedly sleeved on the threaded rod, which meshes with the first rotating gear.

[0012] Preferably, the transmission assembly includes a transmission rack connected to the adjusting block, and a transmission gear ring that meshes with the transmission rack is fixedly sleeved on the rotating ring.

[0013] Preferably, the clamping assembly includes a clamping rod hinged to the mounting ring, a clamping roller being connected to the clamping rod by a bearing, a guide block being connected to the rotating ring by a bearing, and the clamping rod passing through the guide block.

[0014] Preferably, the sliding frame is provided with a limiting component, the limiting component including a limiting post disposed on the sliding frame, the limiting post being used to limit the reverse movement of the connecting rod, and a limiting block disposed on the sliding frame, the limiting block being used to limit the forward movement of the connecting rod.

[0015] The beneficial effects of this invention are as follows: Before welding, two long shaft members are passed through a rotating assembly and a clamping assembly. Due to their length, the ends of the long shaft members tend to tilt slightly downwards. The drive assembly is then activated. In its first motion state, the drive assembly drives the rotating assembly to rotate, which in turn drives the adjusting assembly to move. The adjusting assembly drives the transmission assembly to rotate, which in turn drives the sliding assembly to rotate. The sliding assembly then drives the clamping assembly to clamp the long shaft members. The clamping assembly centers and corrects the long shaft members, forcing them to align coaxially. At this point, although the two long shaft members are coaxial, they are not fully aligned; there is a gap between them. Full alignment is required. During alignment, the drive assembly is activated again, forcing it into a second motion state. Due to its inherent design, when the drive assembly reaches a certain position, it pulls the sliding assembly horizontally (i.e., the sliding assembly retracts horizontally). This retraction causes the adjusting and rotating assemblies to retract synchronously, and the adjusting assembly drives the transmission assembly to retract. The clamping assembly retracts synchronously, clamping the end of the long shaft member. During retraction, the clamping assembly drives the long shaft member to retract as well, forcing the two long shaft members to align, achieving axial adjustment and complete docking. During welding, the clamping assembly holds the long shaft member, and the rotating assembly is activated. The rotating assembly drives the clamping assembly and the long shaft member to rotate. Due to the clamping assembly, the rotation of the end of the long shaft member causes the clamping assembly to rotate, allowing the welding equipment to connect the two shaft members. The long shaft members are welded together. In summary, the processing device for welding long shaft members according to this application can not only correct the end of the long shaft members to make the two long shaft members coaxial and achieve the effect of circumferential adjustment, but also pull the long shaft members to make the two long shaft members fully connected and achieve the effect of axial adjustment. This avoids the phenomenon of slight downward tilting of the end of the long shaft members, reduces the possibility of initial assembly deviation, improves the quality of the weld, improves the joint connection strength, and improves the overall accuracy of the long shaft members.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0019] Example 1: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, a processing device for welding long shaft members according to the present invention includes a processing plate 1, a rotating assembly 2 provided on the processing plate 1, the rotating assembly 2 providing rotational force to achieve ring welding in conjunction with welding equipment, a clamping assembly 3 provided at the output end of the rotating assembly 2 for clamping one end of the long shaft member, a support frame 4 provided on the processing plate 1 and fixed to the processing plate 1, a sliding assembly 5 provided on the support frame 4, the sliding assembly 5 sliding along the length direction of the processing plate 1, a driving assembly 6 connected to the sliding assembly 5 provided on the support frame 4, the driving assembly 6 providing adjustment driving force, an adjusting assembly 7 provided on the sliding assembly 5, the adjusting assembly 7 having the effect of adjustment and locking, and the adjusting assembly... A rotating component 8 is provided between the sliding component 5 and the adjusting component 7, and the rotating component 8 has a transmission function. A transmission component 9 is provided between the sliding component 5 and the adjusting component 7, and the transmission component 9 has a transmission function. A clamping component 10 for clamping the end of the long shaft member is provided on the sliding component 5. The clamping component 10 can clamp the long shaft member and rotates with it when the long shaft member rotates. In the adjustment, when the driving component 6 moves to the first state, the driving component 6 controls the rotating component 8, the adjusting component 7 and the transmission component 9 to move, forcing the clamping component 10 to clamp the long shaft member. When the driving component 6 moves to the second state, the driving component 6 controls the sliding component 5 to move, forcing the clamping component 10 to move, so that the long shaft member is axially connected.

[0020] Working principle: Before welding, two long shaft members are passed through the rotating assembly 2 and the clamping assembly 3. Due to the length of the long shaft members, their ends will slightly tilt downwards. The drive assembly 6 is activated. When the drive assembly 6 is in its first motion state, it drives the rotating assembly 8 to rotate. The rotating assembly 8 drives the adjusting assembly 7 to move, which in turn drives the transmission assembly 9 to rotate. The transmission assembly 9 drives the sliding assembly 5 to rotate, which in turn drives the clamping assembly 10 to clamp the long shaft members. The clamping assembly 10 performs centering and correction of the long shaft members, forcing them to... The two long shaft members are aligned coaxially. Although they are coaxial, they are not fully engaged; a gap exists between them. Full engagement is required. During engagement, drive assembly 6 is activated, forcing it into a second motion state. Due to its inherent design, when drive assembly 6 reaches a certain position, it pulls sliding assembly 5 horizontally, causing it to retract horizontally. This retraction drives adjustment assembly 7 and rotation assembly 8 to retract synchronously, while adjustment assembly 7 retracts transmission assembly 9. During the movement, the sliding component 5 drives the clamping component 10 to retract synchronously. The clamping component 10 clamps the end of the long shaft member. When the clamping component 10 retracts, it drives the long shaft member to retract as well, forcing the two long shaft members to come into contact, thus achieving axial adjustment and complete docking of the long shaft members. During welding, the clamping component 3 clamps the long shaft member, and the rotating component 2 is activated. The rotating component 2 drives the clamping component 3 and the long shaft member to rotate. Due to the clamping component 10, the rotation of the end of the long shaft member drives the clamping component 10 to rotate. The two long shaft members are welded together using welding equipment. In summary, the processing device for welding long shaft members according to this application can not only correct the end of the long shaft members to ensure they are coaxial and achieve circumferential adjustment, but also pull the long shaft members to ensure they are fully aligned and achieve axial adjustment. This avoids slight downward tilting of the ends of the long shaft members, reduces the possibility of initial assembly deviation, improves weld quality, increases joint strength, and enhances the overall precision of the long shaft members.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, a processing device for welding long shaft rods according to the present invention includes a transmission assembly 9 comprising a transmission rack 901 connected to an adjusting block 703, the transmission rack 901 being fixedly connected to the adjusting block 703, and a transmission gear ring 902 meshing with the transmission rack 901 being fixedly sleeved on a rotating ring 503, the transmission gear ring 902 being fixed to the outer ring of the rotating ring 503.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a processing device for welding long shaft members according to the present invention includes a clamping assembly 10 comprising a clamping rod 1001 hinged to a mounting ring 502. The clamping rod 1001 has a certain length, and a clamping roller 1002 is connected to the clamping rod 1001 by a bearing. The axis of the clamping roller 1002 is arranged along the length direction of the long shaft member, so the clamping roller 1002 can clamp the long shaft member, and the long shaft member can drive the clamping roller 1002 to rotate. A guide block 1003 is connected to the rotating ring 503 by a bearing, and the clamping rod 1001 passes through the guide block 1003.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a processing device for welding long shaft rods according to the present invention includes a limiting component 11 on a sliding frame 501. The limiting component 11 includes a limiting post 1101 fixedly connected to the sliding frame 501 and used to limit the reverse movement of the connecting rod 602. A limiting block 1102 is also provided on the sliding frame 501 and fixedly connected to the sliding frame 501. The limiting block 1102 is used to limit the forward movement of the connecting rod 602.

[0030] Working principle: Before welding, two long shaft members are passed through the rotating ring 203 and the clamping block 302. Due to the length of the long shaft members, the ends of the long shaft members will tilt slightly downwards. The electric push rod 601 is activated, and the output end of the electric push rod 601 drives the connecting rod 602 to the first motion state. Since the connecting rod 602 is fixedly sleeved on the rotating shaft 603, it is forced to rotate around the rotating shaft 603 first. The rotation of the rotating shaft 603 drives the rotating gear 1 801 to rotate, which in turn drives the rotating gear 2 802 to rotate, which in turn drives the threaded rod 702 to rotate. Under the guidance of the connecting frame 701, The rotation of the threaded rod 702 causes the adjusting block 703 to move downwards. The adjusting block 703 causes the transmission rack 901 to move downwards. The transmission rack 901 causes the transmission gear ring 902 to rotate. The transmission gear ring 902 causes the rotating ring 503 to rotate. The rotating ring 503 causes the guide block 1003 to rotate, so that the guide block 1003 causes the clamping rod 1001 to rotate around the hinge point. This forces the clamping rod 1001 to drive the clamping roller 1002 to move synchronously until multiple clamping rollers 1002 clamp the long shaft member. This forces the clamping rollers 1002 to center the long shaft member, achieving the correction of the long shaft member and forcing the two long shaft members to be coaxial and corresponding. At this point, although the two long shaft members are coaxial, they are not fully connected, meaning there is a gap between them. They need to be fully connected. During connection, the electric push rod 601 is activated. Due to the limiting post 1101 restricting the continued movement of the connecting rod 602, the output end of the electric push rod 601 drives the connecting rod 602 into a second motion state. At this time, the connecting rod 602 and the sliding frame 501 form an integral unit, forcing the electric push rod 601 to drive the connecting rod 602 and the sliding frame 501 to move horizontally. The sliding frame 501 moves horizontally back, driving the rotating assembly 8, adjusting assembly 7, transmission assembly 9, and clamping assembly 10 to move back synchronously. The clamping roller 1002 clamps the end of the long shaft member. When the clamping roller 1002 moves back, it drives the long shaft member to move back, forcing the two long shaft members to connect, completing the axial adjustment effect of the long shaft members, and achieving full connection of the two long shaft members. During welding, the hydraulic push rod 301 is activated, and its output end drives the clamping block 302 to move, causing the clamping block 302 to clamp the long shaft member. The rotary motor 201 is activated, and its output shaft rotates, driving the drive gear 204 to rotate. The drive gear 204 rotates, driving the driven gear ring 205 to rotate. The driven gear ring 205 rotates, driving the rotating ring 203 to rotate. The rotating ring 203 drives the clamping block 302 and the long shaft member to rotate. Meanwhile, the clamping roller 1002 clamps the end of the long shaft member, and the shaft of the clamping roller 1002 is set along the length of the long shaft member. The rotation of the end of the long shaft member causes the clamping roller 1002 to rotate, thus achieving both clamping and rotation of the long shaft member. The welding equipment is then used to weld the two long shaft members, completing the welding process.

[0031] This device achieves two different motion states by utilizing two processes of a single mechanical motion: 1. Due to the low resistance of rotation, the pulling action of the electric push rod 601 causes the connecting rod 602 to rotate first. Through power transmission, the clamping roller 1002 is forced to clamp the long shaft member, thereby achieving the function of circumferential adjustment. Second, due to the limiting effect of the limiting post 1101, the connecting rod 602 is forced to form an integral part with the sliding frame 501. When the electric push rod 601 continues to pull, it forces the sliding frame 501 and the corresponding parts to retract synchronously, which forces the clamping roller 1002 to drive the long shaft rod to retract, forcing the two long shaft rods to be fully connected, thus achieving the function of axial adjustment.

[0032] This solution not only corrects the end of the long shaft member, ensuring that the two long shaft members are coaxial and achieving circumferential adjustment, but also pulls the long shaft member to ensure that the two long shaft members are fully aligned, achieving axial adjustment. This avoids slight downward tilting of the end of the long shaft member, reduces the possibility of initial assembly deviation, improves weld quality, increases joint connection strength, and enhances the overall precision of the long shaft member.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
