Description

Technical Field

[0001] This utility model belongs to the field of metal container drilling technology, specifically relating to a metal container drilling positioning structure. Background Technology

[0002] Metal container side drilling equipment is a specialized tool for processing holes on the sides of stainless steel pots, kettles, buckets, basins and other kitchen metal utensils. Its core objective is to achieve precise positioning, regular hole shape, no obvious burrs on the edges, and no deformation of the container body on the non-planar side surface of the metal container, ensuring the stability of subsequent accessory installation and the neatness of the product appearance.

[0003] Based on the actual usage needs of kitchen metal containers, these containers mostly need to be fitted with handles on both sides for easy gripping and use. Therefore, when drilling, it is usually necessary to drill holes on both sides of the container at the same time, and two holes need to be drilled on each side. The spacing between the two holes must strictly follow the handle installation standard to ensure that the handle is flat and firm after installation, without any problems such as skewing or loosening.

[0004] To meet the demand for batch, symmetrical drilling, the industry standard is to place a metal container upside down in the center of four drilling machines. Each machine corresponds to one of the two holes on either side of the container. The container is secured using a pre-set positioning device to ensure precise alignment of the four holes. The four machines then start simultaneously, drilling all four holes on both sides of the container in one operation. This synchronous processing method effectively improves production efficiency, ensures the symmetry and consistency of the holes, reduces errors from manual positioning, and is suitable for mass production scenarios.

[0005] However, in actual production, this processing method has a significant problem: after each drilling operation, four round scrap pieces of material, each the same size as the hole, are generated. Because these scrap pieces are cut off from the container body by the drilling machine, there is no dedicated collection device to catch them. They fall directly from the drilling location and scatter randomly on the worktable. As the number of processing batches increases, the scrap accumulates on the worktable, not only occupying the effective operating space of the worktable and affecting the positioning and placement of subsequent metal containers, increasing the risk of positioning errors, but also causing great inconvenience to the workers' cleaning work. Utility Model Content

[0006] The purpose of this invention is to provide a perforated positioning structure for metal containers to solve the problems existing in the background art.

[0007] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0008] A metal container drilling and positioning structure includes a support platform, an operating table on the front side of the support platform, an operating plate on the upper side of the operating table, two workbenches on the upper side of the support platform, two drilling assemblies on each of the two workbenches, and four drilling assemblies pointing towards the center of the support platform. Each drilling assembly includes a mounting plate connected to the workbench, and each mounting plate is equipped with a drilling portion. Each of the four mounting plates has a connecting rod on an opposite side, a limiting post on the upper side of the connecting rod, a sleeve on the side of the limiting post away from the drilling assembly, an installation cavity inside the sleeve, a through hole passing through the limiting post on the inner wall of the installation cavity, a spring-loaded assembly inside the installation cavity, a slider slidably mounted in the installation cavity connected to the spring-loaded assembly, an ejection assembly passing through the through hole on the slider, and a storage assembly matching the ejection assembly on the upper side of the connecting rod.

[0009] The perforated part includes a support plate connected to the mounting plate. A pneumatic cylinder is connected to the support plate. The output shaft of the pneumatic cylinder passes through the support plate and is connected to a sliding member. The sliding member is slidably assembled on the upper side of the support plate. The sliding member is provided with a perforated part, and the perforated part is matched with the position of the ejector assembly.

[0010] The rebound assembly includes a spring, which is disposed in the mounting cavity, and the two sides of the spring are respectively connected to the mounting cavity and the slider.

[0011] The ejector assembly includes an extension rod connected to the slider, and an ejector is fitted on the side of the extension rod that extends out of the through hole.

[0012] The ejector has an inclined surface on its upper side.

[0013] The support platform has a working frame on its upper side, and a rotating rod is rotatably assembled inside the working frame. The rotating rod has a first threaded section and a second threaded section on its left and right sides, respectively. The threads of the first threaded section and the second threaded section are opposite, and the two working tables are respectively threadedly connected to the first threaded section and the second threaded section.

[0014] The rotating rod extends out of the working frame and is equipped with a rotating wheel.

[0015] The storage component includes a storage frame that is connected to a connecting rod.

[0016] A storage box is provided on the front side of the support platform.

[0017] This utility model has the following technical advantages compared with the prior art:

[0018] 1. This structure, by setting connecting rods and limiting posts on opposite sides of the four mounting plates, allows for flexible adjustment of the distance between the two worktables according to the inner diameter of the metal container. This ensures that the four limiting posts fit tightly against the inner wall of the container, achieving precise positioning. During the drilling process, this precise positioning ensures accurate drilling, avoiding problems such as drilling deviation and inconsistent hole diameters, effectively improving drilling quality and guaranteeing the stability and reliability of the metal container in subsequent use.

[0019] 2. Since both workbenches are equipped with drilling components, and all four drilling components point towards the center of the support platform, once the metal container is inverted and secured to the outside of the limiting post, all four drilling components can be activated simultaneously to drill holes in the outer wall of the metal container. This synchronous operation greatly shortens the drilling time and significantly improves work efficiency compared to the traditional method of drilling holes one by one.

[0020] 3. During the drilling process, the waste material generated as the drilling component pushes into the metal container is held by the ejector component. With the help of the rebound component, the waste material is smoothly ejected from the metal container after drilling and falls into the collection component. This design effectively prevents waste material from falling randomly onto the support platform, maintaining a clean working environment, reducing cleaning time and difficulty, and also lowering the risk of waste material damaging the equipment and other components.

[0021] 4. A rotating rod is rotatably mounted inside the working frame on the support platform. The first and second threaded sections on its left and right sides have opposite threads, and the two worktables are connected to these two threaded sections respectively. By rotating the rotating rod, the two worktables can be moved closer or further apart, thereby adjusting the distance between the drilling components on the left and right sides. This flexible structural design allows the drilling and positioning structure to adapt to metal containers of different diameters, greatly improving the versatility and practicality of the equipment.

[0028] Support platform 1, operating platform 11, operating plate 111, workbench 12, mounting plate 13, connecting rod 14, limiting post 2, sleeve 201, mounting cavity 21, through hole 22, slider 23, support plate 3, pneumatic cylinder 31, sliding part 32, drilling part 33, spring 34, extension rod 4, ejector part 41, inclined plane 42, working frame 43, rotating rod 44, first threaded section 45, second threaded section 46, rotating wheel 47, storage frame 48, storage box 49. Detailed Implementation

[0029] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1-4 As shown, the present invention discloses a metal container drilling and positioning structure, including a support platform 1, an operating table 11 on the front side of the support platform 1, an operating plate 111 on the upper side of the operating table 11, two workbenches 12 on the upper side of the support platform 1, each of the two workbenches 12 having two drilling components, all four drilling components pointing towards the center of the support platform 1, each drilling component including a mounting plate 13 connected to the workbench 12, each mounting plate 13 having a drilling part, each of the four mounting plates 13 having a connecting rod 14 on an opposite side, each connecting rod 14 having a limiting post 2 on the upper side, each limiting post 2 having a sleeve 201 on the side away from the drilling components, each sleeve 201 having an installation cavity 21, each installation cavity 21 having a through hole 22 passing through the limiting post 2 on its inner wall, each installation cavity 21 having a spring-loaded component, each spring-loaded component being connected to a slider 23 slidably mounted in the installation cavity 21, each slider 23 having an ejection component passing through the through hole 22, and each connecting rod 14 having a storage component matching the ejection component on its upper side.

[0031] When it is necessary to drill holes on both sides of the metal container, move the two worktables 12 left and right. Since both worktables 12 are equipped with drilling components on their upper sides, and the worktables 12 are connected to the limiting posts 2 via connecting rods 14, adjust the distance between the two worktables 12 until the four limiting posts 2 can match the inner diameter of the metal container, then stop moving the two worktables 12. At this time, the metal container can be inverted and placed on the outside of the four limiting posts 2. The four limiting posts 2 limit the metal container. At this time, the drilling components can be started at the same time, and the drilling components will drill holes in the outer wall of the metal container.

[0032] When the punching assembly punches a hole in a metal container, the punching part of the assembly penetrates the outer shell of the metal container, leaving a hole and completing the punching process. Simultaneously, because the punching part of the assembly pushes into the metal container, the resulting waste material also pushes into the container. This waste material comes into contact with the ejector assembly, which is connected to the slider 23 inside the sleeve 201. This allows the slider 23 to move, causing the springback assembly to compress. Therefore, as the punching part of the assembly pushes inward, it clamps the waste material outside the ejector assembly. The springback pressure of the springback assembly maintains the pushing force of the ejector assembly on the waste material, ensuring that the waste material is positioned between the ejector assembly and the springback assembly. Between the punching components, after punching is completed, the punching part of the punching component exits the metal container. At this time, under the action of the extension of the spring component, the slider 23 is pushed to reset. The slider 23 drives the ejection component to reset. The ejection component keeps the waste material in continuous contact with the punching part of the punching component. Therefore, after the punching part of the punching component is no longer in contact with the metal container, under the action of the extension of the punching component, the waste material is ejected from the metal container until the punching part of the punching component is completely separated from the metal container and no longer in contact with the waste material. At this time, the waste material is ejected from the metal container and falls downward into the storage component under the action of gravity. This design can complete the collection of waste material, and the waste material will not fall randomly onto the support platform 1.

[0033] The punching section includes a support plate 3 connected to the mounting plate 13. A pneumatic cylinder 31 is connected to the support plate 3. The output shaft of the pneumatic cylinder 31 passes through the support plate 3 and is connected to a sliding member 32. The sliding member 32 is slidably mounted on the upper side of the support plate 3. The sliding member 32 is provided with a punching member 33, which matches the position of the ejector assembly.

[0034] The support plate 3 is connected to the mounting plate 13. The support plate 3 can support the pneumatic cylinder 31. The output end of the pneumatic cylinder 31 is connected to the sliding member 32. The sliding member 32 can slide on the upper surface of the mounting plate 13. The sliding member 32 is connected to the punching member 33. Therefore, when the pneumatic cylinder 31 starts to extend, it can drive the sliding member 32 to slide on the upper side of the mounting plate 13. The sliding member 32 then drives the punching member 33 to move towards the metal container until the punching member 33 completes the punching work on the metal container. At this time, the pneumatic cylinder 31 starts to retract, which can drive the sliding member 32 to reset and slide. The sliding member 32 drives the punching member 33 to reset and slide until the punching member 33 is completely separated from the metal container.

[0035] The spring-rebound assembly includes a spring 34, which is disposed in the mounting cavity 21. The two sides of the spring 34 are connected to the mounting cavity 21 and the slider 23, respectively.

[0036] When the slider 23 moves away from the drilling assembly in the mounting cavity 21, it will compress the spring 34. After the slider 23 stops pushing, it can be pushed back to its original position by the extension of the spring 34.

[0037] The ejector assembly includes an extension rod 4 connected to the slider 23, and an ejector 41 is mounted on one side of the extension rod 4 that extends out of the through hole 22.

[0038] The ejector 41 is connected to the slider 23 via the extension rod 4. The ejector 41 can extend out of the metal container. When the metal container is inverted, the inside of the metal container squeezes the ejector 41, causing the ejector 41 to be retracted into the mounting cavity 21. After the metal container is removed, the ejector 41 can be pushed out by the extension of the spring assembly.

[0039] The ejector 41 has an inclined surface 42 on its upper side. The inclined surface 42 is designed so that when the metal container is inverted, the edge of the metal container will contact the inclined surface 42. As the metal container continues to move downward, the ejector 41 will be pushed into the mounting cavity 21 under the guidance of the inclined surface 42.

[0040] The upper side of the support platform 1 is provided with a working frame 43, and a rotating rod 44 is rotatably assembled inside the working frame 43. The left and right sides of the rotating rod 44 are respectively provided with a first threaded section 45 and a second threaded section 46. The threads of the first threaded section 45 and the second threaded section 46 are opposite. The two worktables 12 are respectively threadedly connected to the first threaded section 45 and the second threaded section 46.

[0041] Since the two worktables 12 are threadedly connected to the first threaded section 45 and the second threaded section 46 respectively, when the rotating rod 44 rotates in two directions, it can drive the two worktables 12 to move closer or further apart, thereby adjusting the distance between the drilling components on the left and right sides. This can be adjusted according to the diameter of the metal container.

[0042] The rotating rod 44 extends out of the working frame 43 and is equipped with a rotating wheel 47. The design of the rotating wheel 47 makes it easy for the operator to rotate the rotating rod 44 in two directions.

[0043] The storage component includes a storage frame 48 connected to the connecting rod 14. The storage frame 48 is designed to facilitate the collection of waste by staff.

[0044] A storage box 49 is provided on the front side of the support platform 1. The storage box 49 is designed to make it convenient for staff to place everyday tools in the storage box 49.

[0045] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
