Description

Technical Field

[0001] This utility model relates to the technical field of rib plate processing equipment, specifically to a rib plate welding assembly tooling. Background Technology

[0002] In modern production processes, improving safety, saving production time, and increasing production efficiency have become top priorities, leading to the development of tooling solutions for special workpiece production and processes. The COP series of workpieces is diverse, with a large amount of welding required between the stiffeners and the cylinder body. The stiffeners are slender components, and their dimensions are often too long, too narrow, and too heavy.

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

[0004] I. Currently, the stiffening plates are hoisted and welded to the cylinder body by manual hoisting. However, manual hoisting is inefficient and it is difficult to guarantee the accuracy of the connection.

[0005] Second, the stiffening plates are currently hoisted manually. Since the stiffening plates are slender components, improper hoisting points can easily cause deformation of the stiffening plates, resulting in large deviations in the flatness of the stiffening plates, which further affects the accuracy of the connection between the stiffening plates and the cylinder.

[0006] Third, the types and sizes of stiffening plates and cylinders are diverse, and the current stiffening plate assembly equipment has poor adaptability and is not suitable for the docking process of stiffening plates and cylinders of various sizes. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a rib welding assembly tooling that is simple in structure, highly automated, has high docking accuracy, and avoids rib deformation.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A rib welding assembly fixture for pushing ribs to connect with a cylinder for welding includes a base frame and an intermediate frame. The top of the intermediate frame is provided with a rib assembly platform that can be moved horizontally toward the cylinder. The rib assembly platform is provided with a crossbeam assembly that can be moved horizontally toward the cylinder for pushing the ribs onto the rib assembly platform. The crossbeam assembly is provided with a forward pressing unit for pushing the ribs on the rib assembly platform forward a second time to the front end of the rib assembly platform, and pressing the ribs after they are aligned with the cylinder by the horizontal movement of the rib assembly platform for welding.

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

[0011] The rear side of the rib plate assembly platform, below the crossbeam assembly, is provided with a rib plate feeding platform that can stack multiple rib plates. The rib plate feeding platform can be raised and lowered to lift multiple rib plates one by one and then push them one by one onto the rib plate assembly platform by the crossbeam assembly.

[0012] The rib plate feeding platform is provided with multiple blocking parts at one end away from the rib plate group to prevent the rib plates stacked on the rib plate feeding platform from falling off.

[0013] The bottom of the rib plate feeding platform is equipped with multiple lifting drive components along its length for driving the rib plate feeding platform to rise and fall.

[0014] The crossbeam assembly includes a crossbeam body and multiple forward-pushing and clamping units mounted on the crossbeam body. Both ends of the crossbeam body are provided with sliders. The two sides of the rib plate assembly platform are provided with slide rails that cooperate with the sliders. One of the slide rails is provided with a rack. One end of the crossbeam body is provided with a gear drive component that cooperates with the rack to drive the crossbeam assembly to translate on the rib plate assembly platform. The rear end of the forward-pushing and clamping unit is provided with a downward-protruding push block to push the rib plates on the rib plate feeding platform onto the rib plate assembly platform when the crossbeam assembly translates.

[0015] The forward pressing unit is provided with a first cylinder extending towards the cylinder body. The front end of the first cylinder is provided with a limiting swing rod that can only be raised in the forward direction. When the crossbeam assembly moves backward, the limiting swing rod will not push the stiffener assembly against the stiffener plate on the platform. When the first cylinder moves forward, the limiting swing rod can push the stiffener assembly against the stiffener plate on the platform forward again to the front end.

[0016] The forward pressing unit is equipped with a second cylinder and a pressing arm for pressing the rib plate. The pressing arm is hinged to the forward pressing unit. The second cylinder is vertically installed and its driving end is connected to the pressing arm to drive the pressing arm to lift or press down.

[0017] The stiffener assembly has a stiffener positioning component on one side of the platform. The stiffener positioning component includes a push plate and a moving drive component. The moving drive component drives the push plate to move along the length direction of the stiffener and is used to push the stiffener and the cylinder to align in the length direction.

[0018] The intermediate frame is equipped with multiple forward and backward movement drive mechanisms connected to the stiffener plate assembly platform. The forward and backward movement drive mechanisms include slide rail slider assemblies and gear rack drive assemblies for driving the stiffener plate assembly platform to translate in the direction of the cylinder on the intermediate frame.

[0019] The base frame is equipped with a left-right movement drive mechanism connected to the intermediate frame. The left-right movement drive mechanism also includes a slide rail slider assembly and a gear rack drive assembly, which are used to drive the intermediate frame to move left and right on the base frame to adapt to various specifications of cylinder welding operations.

[0020] Compared with the prior art, the advantages of this utility model are:

[0021] Firstly, the rib welding assembly tooling of this utility model, through the special design of the rib assembly platform 5 and the crossbeam assembly 6, can realize automatic feeding, automatic translation and docking assembly, and automatic clamping and limiting, with a high degree of automation.

[0022] Secondly, the rib welding assembly fixture of this utility model allows the rib assembly platform 5 to be simultaneously moved and pressed against by the push-pressing unit 61, ensuring that the rib 1 and the cylinder 2 are in complete contact and assembled. Then, the push-pressing unit 61 is used to further press it, improving the docking accuracy and effectively preventing rib welding deformation, resulting in excellent welding effect.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0034] like Figures 1 to 6 As shown, the rib welding assembly fixture of this embodiment is used to push the rib 1 to the cylinder 2 for welding. It includes a base frame 3 and an intermediate frame 4. The top of the intermediate frame 4 is provided with a rib assembly platform 5 that can be moved horizontally toward the cylinder 2. The rib assembly platform 5 is provided with a crossbeam assembly 6 that can be moved horizontally toward the cylinder 2 for pushing the rib 1 onto the rib assembly platform 5. The crossbeam assembly 6 is provided with a forward pressing unit 61 for pushing the rib 1 on the rib assembly platform 5 forward a second time to the front end of the rib assembly platform 5, and pressing the rib 1 after it is brought into contact with the cylinder 2 for assembly and welding. The specific implementation principle is as follows:

[0035] During operation, the crossbeam assembly 6 first pushes the feeding stiffener 1 onto the stiffener assembly platform 5 (e.g., ...). Figure 1 As shown in 1(B)), the forward pressing unit 61 on the crossbeam assembly 6 then further operates, pushing the stiffener 1 on the stiffener assembly platform 5 forward a second time to the front end of the stiffener assembly platform 5 (as shown in 1(B)). Figure 1(As shown in 1(A)). Then, the stiffener assembly platform 5 moves towards the cylinder 2, so that the stiffener 1 at the front end contacts the cylinder 2. At the same time, the forward pressing unit 61 also presses against the stiffener 1, so that the stiffener 1 and the cylinder 2 are in complete contact and assembled. Then, the forward pressing unit 61 will further perform the pressing function, pressing the stiffener 1 in place, and then the external welding robot will perform welding.

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

[0037] Firstly, the rib welding assembly tooling of this utility model, through the special design of the rib assembly platform 5 and the crossbeam assembly 6, can realize automatic feeding, automatic translation and docking assembly, and automatic clamping and limiting, with a high degree of automation.

[0038] Secondly, the rib welding assembly fixture of this utility model allows the rib assembly platform 5 to be simultaneously moved and pressed against by the push-pressing unit 61, ensuring that the rib 1 and the cylinder 2 are in complete contact and assembled. Then, the push-pressing unit 61 is used to further press it, improving the docking accuracy and effectively preventing rib welding deformation, resulting in excellent welding effect.

[0039] In this embodiment, a rib plate feeding platform 7 is provided on the rear side of the rib plate assembly platform 5, below the crossbeam assembly 6, for stacking multiple rib plates 1. The rib plate feeding platform 7 is height-adjustable to lift multiple rib plates 1 one by one, which are then pushed one by one onto the rib plate assembly platform 5 by the crossbeam assembly 6. During operation, the rib plate feeding platform 7 is lifted so that the topmost rib plate 1 is raised above the plane of the rib plate assembly platform 5. 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 feeding platform 7, the storage function of multiple rib plates 1 is realized, and the automatic feeding function is realized through lifting. The degree of automation is high, and the manual intervention is greatly reduced.

[0040] In this embodiment, the rib plate feeding platform 7 is provided with multiple blocking parts 71 at the end away from the rib plate assembly platform 5 to prevent the rib plates 1 stacked on the rib plate feeding platform 7 from falling off.

[0041] In this embodiment, the bottom of the rib plate unloading platform 7 is provided with a plurality of lifting drive components 72 along the length direction for driving the rib plate unloading platform 7 to rise and fall. In this embodiment, the lifting drive component 72 is a drive electric cylinder.

[0042] In this embodiment, the crossbeam assembly 6 includes a crossbeam body 62 and multiple forward-pushing and clamping units 61 mounted on the crossbeam body 62. Both ends of the crossbeam body 62 are provided with sliders 63. The sides of the rib plate assembly platform 5 are provided with slide rails 51 that cooperate with the sliders 63. One slide rail 51 has a rack. One end of the crossbeam body 62 has a gear drive component that cooperates with the rack to drive the crossbeam assembly 6 to translate on the rib plate assembly platform 5. The rear end of the forward-pushing and clamping unit 61 has a downward-protruding push block 611 to push the rib plate 1 on the rib plate feeding platform 7 onto the rib plate assembly platform 5 when the crossbeam assembly 6 translates. The gear drive component includes a motor, and the gear and rack on the motor drive shaft mesh to drive the crossbeam assembly 6 to translate on the rib plate assembly platform 5. When the crossbeam body 62 moves horizontally, the downward protruding push block 611 at the rear end of the front push clamping unit 61 will push the stiffening plate 1 on the stiffening plate feeding platform 7 onto the stiffening plate assembly platform 5.

[0043] In this embodiment, the forward pressing unit 61 is equipped with a first cylinder 612 extending towards the cylinder 2. The front end of the first cylinder 612 is equipped with a limiting swing rod 613 that can only be raised forward. This limiting swing rod 613 prevents the stiffener assembly from pushing the stiffener plate 1 on the platform 5 when the crossbeam assembly 6 retracts, and also allows the limiting swing rod 613 to push the stiffener plate 1 on the platform 5 forward a second time when the first cylinder 612 drives forward. The specific implementation principle is as follows:

[0044] When the crossbeam body 62 moves horizontally, the pusher block 611 pushes the stiffening plate 1 on the stiffening plate feeding platform 7 onto the stiffening plate assembly platform 5. Due to space constraints, the crossbeam body 62 cannot continue to move forward and needs to retreat to the initial pushing position. During the retreat, the limiting swing rod 613 on the forward pressing unit 61 will contact the stiffening plate 1. However, since it is mounted via a pivot and can be lifted in the forward direction, the limiting swing rod 613 will not push the stiffening plate 1 on the stiffening plate assembly platform 5 inward. After passing the stiffening plate 1, the lifted limiting swing rod 613 will retreat under the action of gravity. After the crossbeam body 62 retracts to the initial pushing position and stops, the first cylinder 612 drives the limiting swing rod 613 forward. Since the limiting swing rod 613 can only be lifted forward and not backward, the protruding limiting swing rod 613 will contact and push the stiffener 1. Finally, driven by the first cylinder 612, the limiting swing rod 613 pushes the stiffener 1 on the stiffener assembly platform 5 forward a second time to the front end. This design structure is simple and compact, satisfying both the retraction of the crossbeam body 62 after the first push of the stiffener 1 and the second push of the stiffener 1 to the front end of the stiffener assembly platform 5.

[0045] In this embodiment, the front pressing 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 hinged to the front pressing unit 61. The second cylinder 614 is vertically installed and its driving end is connected to the pressing arm 615 to drive the pressing arm 615 to lift or press down.

[0046] After the stiffener 1 is pushed forward a second time to the front end of the stiffener assembly platform 5, the stiffener assembly platform 5 moves horizontally towards the cylinder 2, causing the stiffener 1 at the front end to contact the cylinder 2. At this time, the limiting swing rod 613 simultaneously abuts against the stiffener 1, ensuring that the stiffener 1 and cylinder 2 are fully in contact and assembled. Then, the second cylinder 614 retracts, pulling the hinged pressure arm 615 to move, causing the pressure arm 615 to press down and tighten the stiffener 1, facilitating welding by the external welding robot. After welding is completed, the second cylinder 614 extends, pushing the hinged pressure arm 615 to move, causing the pressure arm 615 to lift and press down.

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

[0048] When the stiffener assembly platform 5 moves towards the cylinder 2, causing the stiffener 1 at the front end to contact the cylinder 2, and at the same time the limiting rocker arm 613 abuts against the stiffener 1, so that the stiffener 1 and the cylinder 2 are fully in contact and aligned, the moving drive component 82 on one side of the stiffener assembly platform 5 will drive the push plate 81 to extend. The moving drive component 82 has a predetermined drive stroke, so that each drive pushes each stiffener 1 to the same position, realizing the alignment of the stiffener 1 and the cylinder 2 in the length direction, that is, realizing the positioning in the length direction before welding.

[0049] In this embodiment, the intermediate frame 4 is provided with a plurality of forward and backward moving drive mechanisms 41 connected to the stiffener assembly platform 5. The forward and backward moving drive mechanism 41 includes a slide rail slider assembly and a gear rack drive assembly to drive the stiffener assembly platform 5 to translate in the direction of the cylinder 2 on the intermediate frame 4.

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

[0051] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
