Description

Technical Field

[0001] The invention relates to the technical field of rib plate processing devices, and in particular to a rib plate welding assembly tool. Background Art

[0002] In modern production processes, improving safety, saving production time and production efficiency have become top priorities, and tooling for special workpiece production and processes has emerged. The COP series has many types of workpieces, and the welding volume of the rib plate and the cylinder is large. The rib plate is a slender piece, the rib plate is too long, the width is too small, and the weight is heavy.

[0003] The existing technical solutions have the following deficiencies:

[0004] 1. Currently, manual lifting is used to lift the rib plate and connect it to the cylinder and then weld it. The work efficiency of manual lifting is low and the connection accuracy is difficult to guarantee.

[0005] 2. Currently, manual lifting is used to lift the rib plates. The rib plates are slender parts. If the lifting point is not in the right position, the rib plates are easily deformed, resulting in large deviations in the flatness of the rib plates, which further affects the docking accuracy between the rib plates and the cylinder.

[0006] 3. The types and sizes of ribs and cylinders are various. The current rib plate assembly has poor adaptability to the device and is not suitable for the docking process of ribs and cylinders of various sizes. Summary of the invention

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a rib plate welding assembly tool which has a simple structure, a high degree of automation, a high docking accuracy and avoids rib plate deformation.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] A rib plate welding assembly tool is used to push the rib plate and the cylinder for welding after docking, comprising a base frame and an intermediate frame, a rib plate assembly platform which can be translated toward the cylinder is provided on the top of the intermediate frame, a crossbeam assembly which can be translated toward the cylinder and is used to push the rib plate onto the rib plate assembly platform, a forward pushing and clamping unit is provided on the crossbeam assembly, which is used to push the rib plate on the rib plate assembly platform forward to the front end of the rib plate assembly platform for a second time, and to clamp the rib plate for welding after the rib plate assembly platform is translated to make the rib plate contact with the cylinder for assembly.

[0010] As a further improvement of the above technical solution:

[0011] A rib plate unloading platform capable of stacking a plurality of rib plates is provided on the rear side of the rib plate assembly platform below the crossbeam assembly.

[0015] The forward pushing and clamping unit is provided with a first cylinder extending toward the cylinder body, and the front end of the first cylinder is provided with a limit swing rod which can only be lifted toward the front side. When the cross beam assembly retreats, the limit swing rod will not push the rib plates on the rib plate group platform, and when the first cylinder is driven forward, the limit swing rod can push the rib plates on the rib plate group platform forward to the front end for a second time.

[0016] The forward pushing and clamping unit is provided with a second cylinder and a pressing arm for pressing the rib plate.

[0017] A rib plate positioning assembly is provided on one side of the rib plate group facing the platform. The rib plate positioning assembly includes a push plate and a movable driving member. The movable driving member drives the push plate to move along the length direction of the rib plate and is used to push the rib plate to align with the cylinder in the length direction.

[0018] The intermediate frame is provided with a plurality of forward and backward moving driving mechanisms connected to the rib plate pair platform, and the forward and backward moving driving mechanisms include a slide rail slider assembly and a gear rack driving assembly, which are used to drive the rib plate pair platform to translate toward the cylinder on the intermediate frame.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] like Figures 1 to 6 As shown, the rib plate welding assembly tool of this embodiment is used to push the rib plate 1 and the cylinder 2 to be welded after docking, and includes a base frame 3 and an intermediate frame 4. The top of the intermediate frame 4 is provided with a rib plate assembly platform 5 that can be translated toward the cylinder 2. The rib plate assembly platform 5 is provided with a crossbeam assembly 6 that can be translated toward the cylinder 2, which is used to push the rib plate 1 onto the rib plate assembly platform 5. The crossbeam assembly 6 is provided with a forward pressing unit 61, which is used to push the rib plate 1 on the rib plate assembly platform 5 forward to the front end of the rib plate assembly platform 5 for a second time, and after the rib plate assembly platform 5 is translated to make the rib plate 1 contact with the cylinder 2 for assembly, the rib plate 1 is pressed for welding. The specific implementation principle is as follows:

[0035] During operation, the crossbeam assembly 6 first pushes the rib plate 1 to be loaded onto the rib plate assembly platform 5 (such as Figure 1 1 (B) in the figure), and then the forward pressing unit 61 on the crossbeam assembly 6 further operates to push the rib plate 1 on the rib plate assembly platform 5 forward to the front end of the rib plate assembly platform 5 (as shown in FIG. Figure 11(A) in the figure). Then the rib plate assembly platform 5 is translated toward the cylinder 2, so that the rib plate 1 at the front end contacts the cylinder 2, and at this time, the forward pressing unit 61 also presses against the rib plate 1, so that the rib plate 1 and the cylinder 2 are completely in contact and assembled. Then the forward pressing unit 61 further realizes the pressing function, pressing the rib plate 1 in contact and assembly, and then uses the external welding robot for welding.

[0036] Through the above special scientific design, it has the following technical advantages:

[0037] First, the rib plate welding assembly tooling of the present invention can realize automatic loading, automatic translation docking assembly, automatic clamping and limiting through special designs of the rib plate assembly platform 5, the crossbeam assembly 6, etc., and has a high degree of automation.

[0038] Second, the rib plate welding assembly tool of the present invention, the rib plate assembly platform 5 is translated and the pressing unit 61 is pressed at the same time, so that the rib plate 1 and the cylinder 2 are completely in contact and assembled. Then the forward pressing unit 61 is used to further press, so that the docking accuracy is improved, and the deformation of the rib plate welding can be effectively avoided, and the welding effect is excellent.

[0039] In this embodiment, a rib plate discharging platform 7 on which multiple rib plates 1 can be stacked is provided at the rear side of the rib plate assembly platform 5 below the crossbeam assembly 6. The rib plate discharging platform 7 can be raised and lowered to lift multiple rib plates 1 one by one and then be pushed one by one onto the rib plate assembly platform 5 by the crossbeam assembly 6. During operation, the rib plate discharging platform 7 is lifted and the uppermost rib plate 1 is lifted above the plane of the rib plate assembly platform 5, and then the crossbeam assembly 6 moves forward to push the first rib plate 1 onto the rib plate assembly platform 5. By setting up the rib plate discharging platform 7, the storage function of multiple rib plates 1 is realized, and the automatic loading function is realized by lifting and lowering, with a high degree of automation, which greatly reduces the degree of manual participation.

[0040] In this embodiment, a plurality of blocking parts 71 are provided at one end of the rib plate discharging platform 7 away from the rib plate assembly platform 5, for preventing the rib plates 1 stacked on the rib plate discharging platform 7 from falling.

[0041] In this embodiment, a plurality of lifting driving members 72 are provided along the length direction at the bottom of the rib plate unloading platform 7, which are used to drive the lifting of the rib plate unloading platform 7. In this embodiment, the lifting driving member 72 is a driving electric cylinder.

[0042] In this embodiment, the cross beam assembly 6 includes a cross beam body 62 and a plurality of forward pressing units 61 mounted on the cross beam body 62. Slide blocks 63 are provided at both ends of the cross beam body 62. Slide rails 51 cooperating with the slide blocks 63 are provided on both sides of the rib plate assembly platform 5. A rack is provided at one of the slide rails 51. A gear driving member cooperating with the rack is provided at one end of the cross beam body 62 to drive the cross beam assembly 6 to translate on the rib plate assembly platform 5. A push block 611 protruding downward is provided at the rear end of the forward pressing unit 61 to push the rib plate 1 on the rib plate discharge platform 7 onto the rib plate assembly platform 5 when the cross beam assembly 6 translates. The gear driving member includes a motor, and the gear on the motor drive shaft is meshed with the rack, so as to drive the cross beam assembly 6 to translate on the rib plate assembly platform 5. When the crossbeam body 62 translates, the downwardly protruding push block 611 at the rear end of the front push and clamp unit 61 pushes the rib plate 1 on the rib plate discharging platform 7 onto the rib plate assembling platform 5 .

[0043] In this embodiment, the forward pressing unit 61 is provided with a first cylinder 612 extending toward the cylinder 2, and the front end of the first cylinder 612 is provided with a limit swing rod 613 that can only be lifted toward the front side, so that when the cross beam assembly 6 retreats, the limit swing rod 613 will not push the rib plate 1 on the rib plate assembly platform 5, and when the first cylinder 612 is driven forward, the limit swing rod 613 can push the rib plate 1 on the rib plate assembly platform 5 forward to the front end for a second time. The specific implementation principle is as follows:

[0044] When the crossbeam body 62 is translated, and the push block 611 is used to push the rib plate 1 on the rib plate discharge platform 7 onto the rib plate assembly platform 5, the crossbeam body 62 cannot move forward due to space limitations and needs to retreat to the initial position of the material pusher. During the retraction process, the limit swing rod 613 on the forward push clamping unit 61 will contact the rib plate 1. However, since it is installed through a rotating shaft and can be lifted toward the front side, the limit swing rod 613 is lifted at this time and will not push the rib plate 1 on the rib plate assembly platform 5 back inward. After passing the rib plate 1, the lifted limit swing rod 613 will retreat under the action of gravity. When the cross beam body 62 retreats to the initial position of the material pusher and stops, the first cylinder 612 will drive the limit swing rod 613 to drive forward. Since the limit swing rod 613 can only be lifted forward but not backward, the protruding limit swing rod 613 will contact and push the rib plate 1. Finally, driven by the first cylinder 612, the rib plate 1 on the rib plate assembly platform 5 is pushed forward to the front end for the second time through the limit swing rod 613. This design structure is simple and compact, which not only meets the requirements of the cross beam body 62 returning the rib plate 1 after the first push, but also realizes the second push forward of the rib plate 1 to the front end of the rib plate assembly platform 5.

[0045] In this embodiment, the forward pushing and clamping unit 61 is provided with a second cylinder 614 and a pressing arm 615 for pressing the rib plate 1. The pressing arm 615 is hingedly mounted on the forward pushing and clamping unit 61. The second cylinder 614 is vertically mounted and the driving end is connected to the pressing arm 615 to drive the pressing arm 615 to lift or press down.

[0046] After the rib plate 1 is pushed forward to the front end of the rib plate assembly platform 5 for the second time, the rib plate assembly platform 5 is translated toward the cylinder 2, so that the rib plate 1 at the front end contacts the cylinder 2, and at this time, the limit swing rod 613 will simultaneously press against the rib plate 1, so that the rib plate 1 and the cylinder 2 are completely in contact and assembled. Then the second cylinder 614 contracts, pulling the hinged pressure arm 615 to move, so that the pressure arm 615 presses down and presses the rib plate 1 tightly, which is convenient for the external welding robot to perform welding. After the welding is completed, the second cylinder 614 extends out, pushing the hinged pressure arm 615 to move, so that the pressure arm 615 is lifted and pressed down.

[0047] In this embodiment, a rib plate positioning assembly 8 is provided on one side of the rib plate group platform 5, and the rib plate positioning assembly 8 includes a push plate 81 and a movable driving member 82. The movable driving member 82 drives the push plate 81 to move along the length direction of the rib plate 1 and is used to push the rib plate 1 to align with the cylinder 2 in the length direction.

[0048] When the rib plate assembly platform 5 is translated toward the cylinder 2, the rib plate 1 at the front end is in contact with the cylinder 2, and the limit swing rod 613 will simultaneously press against the rib plate 1, so that the rib plate 1 and the cylinder 2 are completely in contact and assembled. The moving drive member 82 on one side of the rib plate assembly platform 5 will drive the push plate 81 to extend. The moving drive member 82 has a predetermined driving stroke, so that each driving pushes each rib plate 1 to the same position, so that the rib plate 1 and the cylinder 2 are aligned in the length direction, that is, the length direction positioning before welding is achieved.

[0049] In this embodiment, the intermediate frame 4 is provided with a plurality of forward and backward moving drive mechanisms 41 connected to the rib plate group platform 5. The forward and backward moving drive mechanisms 41 include a slide rail slider assembly and a gear rack drive assembly, which are used to drive the rib plate group platform 5 to translate on the intermediate frame 4 toward the cylinder 2.

[0050] In this embodiment, the base frame 3 is provided with a left-right moving driving mechanism 42 connected to the intermediate frame 4, and the left-right moving driving mechanism 42 also includes a slide rail and slider assembly and a gear rack driving assembly, which is used to drive the intermediate frame 4 to translate left and right on the base frame 3 to adapt to welding operations of cylinders 2 of various specifications. By driving the intermediate frame 4 to translate left and right on the base frame 3, fine adjustment of positions of various specifications in the length direction can be achieved, making the device more adaptable.

Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
