Description

Technical Field

[0001] This utility model relates to the field of assembly machine technology, specifically to a drive structure, riveting structure, and assembly machine for steel clamp assembly. Background Technology

[0002] Steel clamps are widely used in machinery, automotive, and other fields. Their assembly process relies on the coordinated operation of core structures such as drives and riveting, and the assembly accuracy and efficiency directly determine product quality. In existing technologies, the drive structures for steel clamp assembly often suffer from asynchronous lifting and pushing movements, resulting in insufficient positioning accuracy. This can easily lead to difficulties in avoiding the parts being processed, affecting subsequent assembly processes. The riveting structure often malfunctions in conjunction with the drive structure, resulting in low riveting accuracy, uneven forming, and defects such as loose riveting and cracking, failing to meet the requirements of precision assembly. Existing assembly machines have low integration levels, poor coordination between the drive and riveting structures, and often rely on manual assistance or complex, separate designs. This not only makes operation cumbersome and inefficient but also makes it difficult to adapt to the production rhythm of mass steel clamp assembly, and results in a high equipment failure rate. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a driving structure, riveting structure and assembly machine for steel clamp assembly, so as to solve the problems mentioned in the background art that the traditional steel clamp assembly machine has a single function, poor assembly stability and cannot complete the assembly on a single assembly machine.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a driving structure for steel clamp assembly, comprising a base, wherein the base is provided with a lifting part for lifting the workpiece up and down toward the processing station, a pushing part for moving the workpiece back and forth toward the processing station, an intermediate block, and a cylinder. The lifting part, when raised, can support the workpiece; when lowered, it can prevent the workpiece from entering the processing station. The cylinder is connected to the intermediate block, and the cylinder drives the intermediate block to move, thereby causing the pushing part to move toward or away from the processing station. The pushing part is engaged with the intermediate block. One side of the lifting part is slidably connected to the base, and an upper and lower sliding rail is provided between the lifting part and the base. The other side is slidably connected to the intermediate block. The intermediate block has an arc slope on the side facing the lifting part, and the lifting part slides along the arc slope to move the lifting part toward or away from the processing station.

[0005] As a further improvement of this utility model, the lifting and lowering part includes a roller arranged at the position corresponding to the arc slope. The outer peripheral wall of the roller can fit against the arc slope and reciprocate along its length. When the roller rolls to the high point of the arc slope, the lifting and lowering part drives the part to be processed to the processing position. When the roller rolls to the low point of the arc slope, the lifting and lowering part drives the part to be processed away from the processing position and avoids other parts to be processed that are about to pass through the processing position.

[0006] As a further improvement of this utility model, the intermediate block is provided with a first flat surface and a second flat surface. The first flat surface is connected to the end of the low point of the arc slope, and the second flat surface is connected to the end of the high point of the arc slope. When the roller rolls to the first flat surface, the up-and-down lifting part can avoid the part to be processed and allow it to enter the processing position. When the roller rolls to the second flat surface, the up-and-down lifting part can support the part to be processed and place it in the processing position.

[0007] As a further improvement of this utility model, the lifting part includes a pull ring, one end of which is connected to the lifting part and the other end is connected to the base, and the lifting part and the base form a counter-pull.

[0008] This solution also provides a riveting structure for steel clamp assembly, including a base, an extension plate and a drive structure using any of the above improvements, the base having a lifting part for moving the workpiece up and down toward the processing station, the extension plate having a riveting machine positioned above the processing station, and the lifting part supporting the workpiece at the processing station, the riveting machine cooperating with the lifting part to rivet the workpiece.

[0009] As a further improvement of this utility model, the riveting machine is provided with a cylinder and a connecting block. The connecting block is provided with a riveting head at one end facing the processing station, and a slot for engaging with the end of the cylinder at the other end. The cylinder drives the connecting block to move up and down so as to drive the riveting head to rivet the parts to be processed at the processing station.

[0012] Compared with the prior art, this utility model provides a drive structure, riveting structure, and assembly machine for steel clamp assembly, which has the following beneficial effects: the upper and lower lifting parts cooperate with the upper and lower sliding rails of the base to achieve smooth lifting of the parts to be processed. The rising part can stably support the parts, and the lowering part can avoid the parts from entering the processing station, and the switching is convenient; the cylinder drives the intermediate block, which not only drives the front and rear pushing parts to move forward and backward through the snap-fit, but also slides with the lifting part through the arc slope, so that the processing of the parts in the four directions of up, down, front and back can be completed on one machine.

[0019] As shown in the figure, to achieve the above-mentioned objective, this utility model provides a drive structure 22 for steel clamp assembly, including a base 1. The base 1 is provided with a lifting part 4 for lifting the workpiece 2 to be processed up and down towards the processing station 3, a pushing part 5 for moving the workpiece 2 to be processed back and forth towards the processing station 3, an intermediate block 6, and a cylinder 7. When the lifting part 4 is raised, it can support the workpiece 2 to be processed. When the lifting part 4 is lowered, it can prevent the workpiece 2 from entering the processing station. Position 3, cylinder 7 is connected to intermediate block 6, cylinder 7 drives intermediate block 6 to move so as to drive front and rear pushing parts 5 to move toward or away from processing station 3. Front and rear pushing parts 5 are engaged with intermediate block 6. One side of the upper and lower lifting part 4 is slidably connected to base 1. There is an upper and lower sliding rail 9 between the upper and lower lifting part 4 and base 1. The other side is slidably connected to intermediate block 6. Intermediate block 6 is provided with an arc slope 10 on the side facing the upper and lower lifting part 4. The upper and lower lifting part 4 slides along the arc slope 10 so as to drive the upper and lower lifting part 4 to move toward or away from processing station 3.

[0020] In implementation, the base 1 is fixed to the ground using brackets or table legs, providing a stable foundation for the installation of all functional components. The base 1 is equipped with a vertical lifting section 4, a front and rear pushing section 5, an intermediate block 6, and a cylinder 7. One side of the vertical lifting section 4 is connected to the base 1 by an upper and lower sliding rail 9, ensuring precise vertical sliding and maintaining the vertical movement accuracy of the vertical lifting section 4. The other side of the vertical lifting section 4 is slidably connected to the intermediate block 6. The side of the intermediate block 6 facing the vertical lifting section 4 has an integrally formed arc slope 10 structure, providing guidance for the lifting action of the vertical lifting section 4. The output end of the cylinder 7 is fixedly connected to the intermediate block 6, while the front and rear pushing section 5 is assembled with the intermediate block 6 using a snap-fit ​​method, achieving coordinated operation between the two. After the cylinder 7 is started, it drives the intermediate block 6 to move horizontally back and forth. When the intermediate block 6 moves, it drives the front and rear pushing parts 5 to move horizontally in a direction closer to or away from the processing station 3. On the other hand, through the sliding cooperation between the arc slope 10 and the upper and lower lifting parts 4, it drives the upper and lower lifting parts 4 to move up and down along the upper and lower sliding rails 9. When the upper and lower lifting parts 4 rise to the preset position, its top surface can stably support the steel clamp part to be processed. When the upper and lower lifting parts 4 fall to the preset position, its whole body is in the area below the processing station 3, which can avoid the steel clamp part to be processed and smoothly enter the processing station 3. The linkage of the part's station transport and avoidance action is completed. The up and down lifting and forward and backward movement can be realized synchronously by the cylinder 7 pulling the intermediate block 6. The structure is simple, the operation is convenient, and no manual adjustment is required.

[0021] As an improved specific implementation, the lifting part 4 includes a roller 11 positioned corresponding to the arc slope 10. The outer peripheral wall of the roller 11 can fit against the arc slope 10 and reciprocate along its length. When the roller 11 rolls to the high point of the arc slope 10, the lifting part 4 moves the part to be processed 2 to the processing station 3. When the roller 11 rolls to the low point of the arc slope 10, the lifting part 4 moves the part to be processed 2 away from the processing station 3 and avoids other parts to be processed 2 that are about to pass through the processing station 3.

[0022] In implementation, a roller 11 is rotatably mounted on the upper and lower lifting part 4 at the corresponding position facing the arc slope 10 of the intermediate block 6. The roller 11 is made of wear-resistant metal and has a smooth arc surface on its outer peripheral wall, which can fit tightly against the surface of the arc slope 10 of the intermediate block 6 and can perform a smooth reciprocating rolling motion along the length of the arc slope 10. The roller 11 is connected to the upper and lower lifting part 4 through a rotating shaft, ensuring the rotational flexibility of the roller 11 and effectively reducing frictional loss between it and the arc slope 10. During the movement of the intermediate block 6 driven by the cylinder 7, the roller 11 moves synchronously along the arc slope 10 with the intermediate block 6. When the roller 11 rolls to the high point of the arc slope 10, under the pushing action of the arc slope 10, the upper and lower lifting part 4 slides upward along the upper and lower sliding rails 9 of the base 1 to the highest position. At this time, the support surface of the upper and lower lifting part 4 is flush with the reference surface of the processing station 3, which drives the steel clamp part to be processed to be stably placed in the processing station 3, preparing for subsequent processing. When the roller 11 rolls to the low point of the arc slope 10, the upper and lower lifting part 4 loses the pushing action of the arc slope 10 and slides downward along the upper and lower sliding rails 9 to the lowest position, which drives the steel clamp part to be processed away from the processing station 3. At this time, the passage of the processing station 3 is completely unobstructed, which can effectively avoid other steel clamp parts to be processed that are about to pass through the processing station 3, and avoid interference between parts.

[0023] As an improved specific implementation, the intermediate block 6 is provided with a first flat surface 12 and a second flat surface 13. The first flat surface 12 is connected to the end of the low point of the arc slope 10, and the second flat surface 13 is connected to the end of the high point of the arc slope 10. When the roller 11 rolls to the first flat surface 12, the up-and-down lifting part 4 can avoid the part to be processed 2 and allow it to enter the processing station 3. When the roller 11 rolls to the second flat surface 13, the up-and-down lifting part 4 can support the part to be processed 2 and place it in the processing station 3.

[0024] In implementation, this solution incorporates a first flat surface 12 and a second flat surface 13 integrally formed on the intermediate block 6. Both the first flat surface 12 and the second flat surface 13 are horizontal planes and are integrally formed with the arc slope 10. One end of the first flat surface 12 is smoothly connected to the end of the arc slope 10 at its lowest point, with no step difference between them, ensuring that the roller 11 can smoothly roll from the lowest point of the arc slope 10 to the first flat surface 12. Similarly, one end of the second flat surface 13 is smoothly connected to the end of the arc slope 10 at its highest point, also without step difference, enabling the roller 11 to smoothly transition from the highest point of the arc slope 10 to the second flat surface 13. When the cylinder 7 drives the intermediate block 6 to move to the preset position, and the roller 11 rolls to the first flat surface 12 and keeps in contact with the first flat surface 12, the lifting part 4 is kept in the lowest descending position under the limiting action of the roller 11. At this time, the lifting part 4 cannot continue to move up and down, and stably achieves the avoidance effect on the steel clamp component, ensuring that the part to be processed 2 smoothly enters the processing station 3. When the roller 11 rolls to the second flat surface 13 and keeps in close contact with the second flat surface 13, the lifting part 4 is kept in the highest rising position under the limiting action of the roller 11. Its supporting surface is always relatively flush with the processing station 3, ensuring that the steel clamp component to be processed is stably placed in the processing station 3, avoiding displacement of the component during subsequent processing, and improving the stability and accuracy of processing.

[0025] As an improved specific embodiment, the lifting part 4 includes a pull ring 14, one end of which is connected to the lifting part 4 and the other end is connected to the base 1, forming a pull relationship between the lifting part 4 and the base 1.

[0026] In this implementation, a pull ring 14 structure is added to the upper and lower lifting part 4. The number of pull rings 14 is one or two, symmetrically assembled on both sides of the upper and lower lifting part 4. One end of the pull ring 14 is fixedly connected to the side wall of the upper and lower lifting part 4, and the other end is fixedly connected to the corresponding fixed point of the base 1, so that a stable counter-pull engagement relationship is formed between the upper and lower lifting part 4 and the base 1. The pull ring 14 is an elastic metal spring pull ring 14, which has good elastic extension and contraction performance. When the upper and lower lifting part 4 moves up and down along the upper and lower sliding rails 9, the spring pull ring 14 can extend and contract synchronously with the movement of the lifting part, always providing a continuous counter-pull force for the upper and lower lifting part 4, ensuring the sliding fit between the lifting part and the intermediate block 6, and preventing the lifting part from separating from the arc slope 10. In other solutions, the pull ring 14 can also be made of other materials with elastic restoring characteristics.

[0027] This solution also provides a massage device, including a base 1, an extension plate 15 and a drive structure 22 of any of the above-mentioned improvements on the base 1, an up-and-down lifting part 4 for lifting the part to be processed 2 up and down toward the processing station 3, a riveting machine 16 on the extension plate 15, the riveting machine 16 being positioned above the processing station 3, when the up-and-down lifting part 4 supports the part to be processed at the processing station 3, the riveting machine 16 and the up-and-down lifting part 4 cooperate to rivet the part to be processed 2.

[0028] In this implementation, the installation position of the drive structure 22 is adapted to the position of the processing station 3, with its lifting part 4 facing the lower area of ​​the processing station 3. The extension plate 15 is made of the same hard metal material as the base 1 and is vertically assembled to one side of the base 1 by bolts. The extension direction of the extension plate 15 faces upward towards the processing station 3, and its top is a horizontal mounting surface for mounting the riveting machine 16. The riveting machine 16 is fixedly connected to the top of the extension plate 15 through a flange, and the working end of the riveting machine 16 faces directly upward towards the processing station 3 to ensure precise alignment of the riveting action. When the riveting structure 23 is working, the cylinder 7 of the drive structure 22 first drives the intermediate block 6 to move, which in turn drives the upper and lower lifting parts 4 to rise and support the steel clamp component to be processed in the processing station 3. At the same time, the front and rear pushing parts 5 push the component to be processed 2 to be positioned tightly to prevent the component from shifting. After the steel clamp component to be processed is stably placed in the processing station 3, the riveting machine 16 starts and its working end moves downward to cooperate with the upper and lower lifting parts 4 of the drive structure 22. The riveting pressure is applied from above the steel clamp component, while the upper and lower lifting parts 4 provide a stable lower support force for the steel clamp component. The two work together to rivet the steel clamp component to be processed, completing the riveting assembly process of the steel clamp.

[0029] As an improved specific implementation, the riveting machine 16 is provided with a cylinder 7 and a connecting block 17. The connecting block 17 is provided with a riveting head 18 at one end facing the processing station 3, and a slot 19 for engaging with the end 20 of the cylinder 7 at the other end. The cylinder 7 drives the connecting block 17 to move up and down so as to drive the riveting head 18 to rivet the part 2 to be processed on the processing station 3.

[0030] In this implementation, the riveting machine 16 is equipped with a cylinder 7 and a connecting block 17. The cylinder 7 provides power output to the riveting machine 16, and its output end reciprocates in the vertical direction. The connecting block 17 serves as a power transmission component, connecting the cylinder 7 to the riveting execution end. A square slot 19 is provided at the end of the connecting block 17 away from the processing station 3. The inner wall of the square slot 19 is a smooth plane, which is adapted to the end 20 of the cylinder 7. The end 20 of the cylinder 7 is engaged in the square slot 19 and can also be fixed secondary by bolts to prevent relative rotation between the connecting block 17 and the end 20 of the cylinder 7.

[0031] This solution also provides an assembly machine for steel clamp assembly, including a machine body 21, in which a drive structure 22 is provided. The drive structure 22 adopts any of the above-mentioned improved solutions and is fixedly connected to the machine body 21.

[0032] The main body of the assembly machine is the machine body 21, which is welded from structural steel. Inside, there is a processing chamber for steel clamp assembly. This chamber contains multiple workstations for steel clamp conveying, positioning, and assembly. The drive structure 22, as the core power drive component of the assembly machine, is mounted at the positioning workstation within the processing chamber of the machine body 21. It is rigidly connected to the inner wall of the machine body 21 using bolts, ensuring the stability of the drive structure 22 during operation and preventing loosening due to vibration. The drive structure 22 is installed in conjunction with the steel clamp conveying track of the assembly machine. Its front and rear pushing parts 5 face the discharge end of the conveying track, while its vertical lifting parts 4 are located below the positioning workstation. When the assembly machine is working, the steel clamp component is transported to the positioning station via the conveyor rail. The cylinder 7 of the drive structure 22 is activated, which drives the intermediate block 6 to move. On the one hand, the front and rear pushing parts 5 push the steel clamp component on the conveyor rail into the positioning station. On the other hand, the arc slope 10 drives the upper and lower lifting parts 4 to rise, stably supporting the steel clamp component in the positioning station. This provides precise component positioning and support for the subsequent steel clamp assembly process. All the actions of the drive structure 22 are linked with the overall control system of the assembly machine.

[0033] An assembly machine for assembling steel clamps includes a machine body 21, wherein the riveting structure 23 adopts the riveting structure 23 as described in the above-described improved scheme, and the riveting structure 23 is fixedly connected to the machine body 21.

[0034] In implementation, the riveting structure 23 is assembled at the riveting station of the machine body 21 and is fixedly connected to the frame of the machine body 21 by welding and bolt reinforcement, ensuring that the riveting structure 23 has no displacement or vibration during high-intensity riveting operations. The processing station 3 of the riveting structure 23 is connected to the conveying mechanism of the assembly machine. After the steel clamp component is conveyed to the processing station 3 of the riveting structure 23 by the conveying mechanism, the drive structure 22 of the riveting structure 23 completes the positioning and support of the component, and then the riveting machine 16 starts to perform the riveting operation.

[0035] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
