Description

Technical Field

[0001] The present application relates to a welding and plugging machine, in particular to a double-head welding and plugging machine. Background Art

[0002] The roller is composed of a hollow steel pipe and two end covers. The end covers are annular in structure and have holes. When assembling the roller, it is often necessary to use a welding machine to weld the end covers that are interference-fitted at the ends of the hollow steel pipe to complete the processing of the roller.

[0003] A double-head welding and plugging machine in the related technology includes a workbench, two movable seats, a rotating shaft arranged on the movable seats, a support seat and a welding gun, wherein the support seat is located between the two movable seats, and the support seat is used to support a hollow steel pipe. The workbench is provided with a device for controlling the two movable seats to move toward each other so that the rotating shaft can be inserted into the rotating hole, and the movable seat is provided with a driving source for driving the rotating shaft to drive the roller to rotate. The welding gun is arranged on the side of the movable seat facing the support seat, and the welding gun is used to weld the end cover and the connecting end of the hollow steel pipe.

[0004] With respect to the above-mentioned related technologies, the inventors believe that when the end cover is welded to the end of the hollow steel pipe, the temperature of the roller is relatively high, and it is usually necessary to wait for the roller to cool down before unloading the roller. The processing cycle is relatively long, and there is still room for improvement. Summary of the invention

[0005] In order to effectively shorten the processing cycle of the roller, the present application provides a double-head welding machine.

[0006] The present application provides a double-head welding and plugging machine, which adopts the following technical solution:

[0007] A double-head welding and plugging machine, comprising a workbench and a support seat, and also comprising a material storage frame, a material discharge frame, a material feeding assembly and a linkage assembly, wherein the material storage frame is used to stack rollers to be welded, and the material discharge frame is used to accommodate rollers that have been welded;

[0008] The support seat includes a feed plate connected to the material storage frame and a feed unloading plate connected to the feed plate. When the roller is placed on the support seat, the feed plate and the feed unloading plate are both tangent to the peripheral side of the roller. The feed unloading plate is rotatably connected to the feed plate. The feed unloading plate can be rotated toward the direction close to the feed plate to a use state for being tangent to the roller. The feed unloading plate can be rotated toward the direction away from the feed plate to a feed unloading state connected to the feed unloading frame.

[0009] The material feeding assembly includes a material pushing member and a material pushing plate. The material storage frame has a material feeding port connected to the inner cavity on the side facing the material feeding plate. The material pushing plate is slidably connected to the material storage frame. The material pushing member is used to drive the material pushing plate to push the roller out of the material feeding port.

[0010] When the roller to be welded is pushed out of the feed port by the pushing plate, the linkage assembly can drive the unloading plate to rotate to the unloading state. When the pushing plate is retracted into the storage frame, the linkage assembly can drive the unloading plate to rotate to the use state to support the roller to be welded.

[0011] By adopting the above technical solution, after the welding of the roller is completed, the pushing member drives the pushing plate to move toward the direction close to the feeding port. At this time, under the action of the linkage component, the unloading plate rotates to the unloading state, so that the welded roller slides into the unloading frame. Then, when the pushing plate is retracted into the storage frame, under the action of the linkage component, the unloading plate rotates to the use state. At this time, the roller pushed out of the feeding port by the pushing plate reaches the support seat through the feeding plate, which is convenient for continuing the welding operation, thereby effectively shortening the processing cycle of the roller.

[0012] Optionally, side plates for abutting against end covers are provided on opposite sides of the conveying plate.

[0013] By adopting the above technical solution and setting the side plates, the possibility of the rollers sliding out of the conveying plate can be reduced.

[0014] Optionally, the linkage assembly includes a driving sprocket, a driven sprocket and a transmission chain corresponding to the side plates one by one, and the linkage assembly also includes a gear and a rack; the driving sprocket is rotatably connected to the bottom of the material storage frame, the driven sprocket is fixedly connected to the rotation center of the unloading plate, the transmission chain is sleeved between the driving sprocket and the driven sprocket, the rack is fixedly connected to the lower end of the pushing plate, the gear and the driving sprocket are coaxially arranged, and the gear is meshed with the rack.

[0015] By adopting the above technical solution, when the push plate moves toward the direction close to the feed port, the rack drives the gear to rotate, so that the gear drives the active sprocket to rotate, and under the action of the transmission chain, it can drive the driven gear to rotate, so that the unloading plate rotates to the unloading state to complete the unloading of the welded roller.

[0016] Optionally, the pushing member is a cylinder, which is installed on a material storage frame, and a piston rod of the cylinder is fixedly connected to a pushing plate.

[0017] By adopting the above technical solution, the cylinder is set as a material pushing member, which has the advantages of simple structure and labor saving.

[0018] Optionally, an abutment portion is provided at one end of the blanking plate away from the rotation center, and when the blanking plate is in a blanking state, the abutment portion abuts against the upper end of the blanking frame.

[0019] By adopting the above technical solution, when the unloading plate rotates to the unloading state, the abutting portion abuts against the upper end of the unloading frame, so that the supporting roller can stably slide into the unloading frame.

[0020] Optionally, two hinged plates are spaced apart at the bottom of the storage frame, a mounting shaft is rotatably connected between the two hinged plates, the two driving sprockets are fixedly connected to the mounting shaft, and the gear is fixedly connected to the mounting shaft.

[0021] By adopting the above technical solution and setting the mounting shaft, the driving sprocket and the gear can be installed.

[0022] Optionally, the bottom wall of the blanking frame is provided with an elastic pad.

[0023] By adopting the above technical solution, the provision of the elastic pad can play a buffering role on the roller.

[0024] Optionally, the material storage frame is provided with a mounting plate, and the cylinder is mounted on the mounting plate by bolts.

[0025] By adopting the above technical solution and setting the mounting plate, the cylinder can be easily installed.

[0026] In summary, the present application includes at least one of the following beneficial effects:

[0027] 1. This application can facilitate the unloading of the welded roller, thereby effectively shortening the processing cycle of the roller;

[0028] 2. The side plates are arranged to reduce the possibility of the rollers sliding off the conveyor plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] The present application embodiment discloses a double-head welding machine. Figure 1The double-head welding machine includes a workbench 1, a support seat 2, a material storage frame 3, a material discharge frame 4, a material feeding assembly 5 and a linkage assembly 6. The lower end of the material storage frame 3 is fixedly connected to a plurality of supporting feet, the supporting feet are fixedly connected to the workbench 1, and the material discharge frame 4 is fixedly connected to one end of the workbench 1 away from the material storage frame 3.

[0034] Reference Figure 1 The rollers 7 to be welded are stacked and placed in the storage frame 3. The storage frame 3 has a feeding port 31 for passing a roller 7 on the side close to the support seat 2. The unloading frame 4 is located on the side of the support seat 2 away from the storage frame 3, and the unloading frame 4 is used to accommodate the rollers 7 after welding.

[0035] Reference Figure 2 The feeding assembly 5 includes a pushing member and a pushing plate 52, and the pushing plate 52 is slidably connected to the material storage frame 3. The pushing member is a cylinder 51, and a mounting plate is fixedly connected to the bottom of the material storage frame 3 on the side away from the feeding port 31, and the cylinder 51 is mounted on the mounting plate by bolts. The piston rod of the cylinder 51 is fixedly connected to the pushing plate 52. When the cylinder 51 is started, the piston rod of the cylinder 51 drives the pushing plate 52 to push a roller 7 out of the feeding port 31, and the upper end of the pushing plate 52 abuts against the next roller 7.

[0036] Reference Figure 2 The support seat 2 includes a feed plate 22 and a feed plate 21. The feed plate 22 is connected to the feed plate 21. The upper end of the feed plate 22 is fixedly connected to the material storage frame 3. When the roller 7 is pushed out of the material storage frame 3 from the feed port 31, the roller 7 can slide down along the inclined direction of the feed plate 22 until it reaches the support seat 2. At this time, the feed plate 22 and the feed plate 21 are tangent to the peripheral side of the roller 7. A vertical plate is fixedly connected to the bottom of the feed plate 22, and the vertical plate is used to support the feed plate 22 on the workbench 1.

[0037] Reference Figure 2 The two opposite sides of the feeding plate 22 are fixedly connected with side plates 8, and the side plates 8 are used to abut against the end covers 11, so as to improve the stability of the roller 7 during the feeding process.

[0038] Reference Figure 1 , 2 , the lower plate 21 is rotatably connected with the feed plate 22, and the two opposite sides of the lower plate 21 protrude to form a rotation axis, and the lower plate 21 is rotatably connected with the feed plate 22 through the rotation axis. The lower plate 21 can be rotated toward the feed plate 22 to a state of being tangent to the peripheral side of the roller 7, at which time a flared structure with an opening upward is formed between the upper plate and the feed plate 22. The lower plate 21 can also be rotated toward the direction away from the feed plate 22 to a state of being connected to the lower frame 4, at which time the lower plate 21 and the feed plate 22 are in the same straight line position, so that the lower plate 21 and the feed plate 22 form a climbing structure, and the welded roller 7 can slide down the climbing slope into the lower frame 4.

[0039] Reference Figure 1 The linkage assembly 6 includes a driving sprocket 61, a driven sprocket 62 and a transmission chain 63 corresponding to the side plates 8. The two opposite sides of the material storage frame 3 are fixedly connected with hinged plates 9, and the hinged plates 9 are located at the bottom of the material storage frame 3. A mounting shaft is rotatably connected between the two hinged plates 9 through a bearing, and the two driving sprockets 61 are respectively fixedly connected to the two ends of the mounting shaft, and the driven sprocket 62 is fixedly connected to the end of the rotating shaft, and the transmission chain 63 is sleeved on the driving sprocket 61 and the driven sprocket 62.

[0040] Reference Figure 1 , 2 The linkage assembly 6 also includes a gear 64 and a rack 65 meshing with the gear 64. The gear 64 is fixedly connected to the middle position of the installation shaft, and the rack 65 is fixedly connected to the lower end of the push plate 52. When the piston rod of the cylinder 51 drives the push plate 52 to push the roller 7 to slide out of the feed port 31, the rack 65 meshes with the gear 64, thereby driving the gear 64 to rotate, so that the installation shaft drives the active sprocket 61 to rotate, and under the action of the transmission chain 63, the driven sprocket 62 can be driven to rotate synchronously, so that the rotating shaft rotates, so that the blanking plate 21 rotates to the blanking state. At this time, the roller 7 that has completed welding slides into the blanking frame 4, and then the piston rod of the cylinder 51 drives the push plate 52 to slide in the direction away from the feed port 31, and the rack 65 drives the gear 64 to rotate in the opposite direction, thereby driving the blanking plate 21 to rotate to the use state, and can receive the roller 7 pushed out of the feed port 31 for subsequent welding operations.

[0041] Reference Figure 2 A contact portion 12 is provided at one end of the unloading plate 21 away from the rotating shaft. When the unloading plate 21 rotates in a direction away from the feeding plate 22 to a unloading state, the contact portion 12 abuts against the upper end of the unloading frame 4, so that the roller 7 can stably slide into the unloading frame 4.

[0042] Reference Figure 2 The bottom wall of the blanking frame 4 is provided with an elastic pad 13. In this embodiment, rubber is used as the elastic pad 13. In other embodiments, other materials with deformation ability can also be used as the elastic pad 13. When the roller 7 falls into the blanking frame 4, the elastic pad 13 can play a buffering role.

[0043] Reference Figure 2 A rubber pad 14 is provided on the top wall of the feed port 31. The rubber pad 14 is used to abut against the upper end of the roller 7. When the roller 7 located at the upper end of the push plate 52 falls to a relative position with the feed port 31, the rubber pad 14 abuts against the upper end of the roller 7, so that the roller 7 is not easy to slide out of the feed port 31 without being subjected to external force, thereby improving the safety of the feeding process.

[0044] The implementation principle of a double-head welding and plugging machine in the embodiment of the present application is:

[0045] When unloading, the cylinder 51 is started, and the piston rod of the cylinder 51 drives the push plate 52 to move toward the direction close to the feeding port 31. During this process, the gear 64 is meshed with the rack 65 to drive the active sprocket 61 to drive the driven sprocket 62 to rotate, so that the unloading plate 21 rotates to the unloading state, and the welded roller 7 rolls along the unloading plate 21 into the unloading frame 4, and then drives the push plate 52 to move away from the feeding port 31, and the rack 65 drives the gear 64 to rotate, so that the unloading plate 21 rotates to the use state, and the roller 7 pushed out of the feeding port 31 can be received for subsequent welding.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
