Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0016] Please see Figures 1-6 This utility model provides a technical solution: A flange drilling processing device for rapid positioning and clamping includes a worktable 1, a support column 2, and an electric hydraulic cylinder 3. A support component 4 is fixedly connected to the top of the support column 2. A clamping and positioning component 5 is installed near the upper end of the support component 4. A pushing component 6 is slidably connected to the inner side of the support component 4. A flange 7 is placed on the upper end of the pushing component 6. The support component 4 includes a base plate 41. The clamping and positioning component 5 includes a movable disk 51. A second guide hole 52 and a receiving groove 59 are opened on the inner side of the movable disk 51. A vertical block 53 is fixedly connected to the top of the movable disk 51. A guide groove 54 is opened on the inner side of the vertical block 53. A rail block 56 is slidably connected to the inner side of the guide groove 54. A clamping block 55 is fixedly connected to one side of the rail block 56. An extension block 57 is fixedly connected to the upper end of the clamping block 55. A second spring 58 is fixedly connected to one side of the extension block 57. The other end of the second spring 58 is fixedly connected to the vertical block 53.
[0017] As a further implementation of this solution, the workbench 1 is fixedly connected to the cylinder body of the electric hydraulic cylinder 3, and a support column 2 is fixedly connected to the top of the workbench 1. The top of the support column 2 is fixedly connected to the bottom of the base plate 41. Through the above settings, the stability of the component connection can be improved, while providing space for the installation of the electric hydraulic cylinder 3, ensuring the accuracy of power transmission, avoiding the impact of loose connection on the reliability of positioning, clamping and ejection actions during operation, and helping the device to operate stably. As a further implementation of this solution, a first guide hole 42 is provided on the inner side of the substrate 41. A pressing plate 43, a storage plate 44 and a first spring 45 are fixedly connected to the top of the substrate 41. A pressing slope 46 is provided near the upper end of the pressing plate 43. Through the above settings, the first guide hole 42 provides a stable sliding guide for the pull rod 61. The pressing plate 43 and the pressing slope 46 can cooperate with the clamping block 55 to achieve precise triggering of the clamping action. The storage plate 44 provides installation limit for the first spring 45. The first spring 45 provides elastic support for the reset action. The overall structure layout is reasonable, which can ensure the smooth connection of the positioning, clamping and reset process and improve the reliability of the device operation. As a further implementation of this solution, the first spring 45 is located inside the receiving plate 44 and outside the first guide hole 42. The top of the first spring 45 is in contact with the bottom of the moving disk 51, one side of the extrusion plate 43 is in contact with the outside of the moving disk 51, and the extrusion slope 46 is aligned with the inclined surface opened at the lower end of the clamping block 55. Through the above settings, the force can be accurately transmitted, ensuring that the clamping is in place when clamping and the springback is smooth when resetting, thereby improving the positioning and clamping accuracy and the convenience of workpiece disassembly, and reducing operation jamming. As a further implementation of this solution, the push component 6 includes a pull rod 61, with a groove 62 on the outer side of the pull rod 61. A support plate 63 is fixedly connected to the top of the pull rod 61, and a flange 7 is placed on the upper end of the support plate 63. Through the above settings, a stable bearing benchmark is provided for the flange workpiece, which facilitates the initial placement and positioning of the workpiece. In conjunction with the subsequent sliding structure, the workpiece can be lifted and lowered, which helps to carry out automatic correction and ejection actions and reduces the difficulty of manual placement. As a further implementation of this solution, the pull rod 61 is slidably connected to the inner side of the first guide hole 42 and the inner side of the second guide hole 52 through the opened slide groove 62. The outer diameter of the support plate 63 is the same as the opening diameter of the receiving groove 59. Through the above settings, the pull rod 61 is ensured to slide smoothly without deviation, improving the workpiece lifting accuracy. At the same time, it is adapted to the installation size of the receiving groove 59 to avoid shaking during operation, further ensuring the flange shaft alignment accuracy and reducing processing errors. As a further implementation of this solution, the end of the stand block 53 near the receiving groove 59 is an arc-shaped surface. The arc-shaped surface of the stand block 53 is aligned vertically with the outer periphery of the receiving groove 59. The clamping block 55 is housed inside the guide groove 54. The upper surface of the stand block 53 has a chamfered structure. Through the above settings, the arc-shaped surface and the chamfered structure can assist the flange workpiece in automatically correcting its axis and improving the positioning accuracy. The design of the clamping block 55 avoids interference with the pallet 63 when idle, and at the same time facilitates quick extension when clamping, taking into account both positioning effect and operational flexibility. The chamfered structure of the stand block 53 can prevent the center of the flange 7 from being aligned with the center of the pallet 63. When the pallet 63 moves downward, the flange 7 cannot move after contacting the stand block 53.
[0018] Workflow: When clamping flange 7, flange 7 is placed on the upper surface of support plate 63, roughly aligned vertically with support plate 63. At this time, the electric hydraulic cylinder 3 is controlled by the existing controller. Initially, support plate 63 is located at the top of multiple upright blocks 53. The electric hydraulic cylinder 3 drives the pull rod 61 downwards. The pull rod 61 slides through the slide groove 62 inside the first guide hole 42, driving support plate 63 downwards. Flange 7 also moves downwards. When the edge of flange 7 contacts the upper surface of upright block 53, the chamfered upper surface of upright block 53 automatically corrects flange 7, thus aligning the flange 7's axis. The center of the plate 63 is aligned with the axis of the support plate 63. When the support plate 63 is inside the receiving groove 59, the flange 7 is located at the upper end of the receiving groove 59. At this time, the support plate 63 will drive the moving plate 51 to move downward. The bottom end of the moving plate 51 is compressed with the first spring 45. When the inclined surface of the clamping block 55 contacts the extrusion slope 46, the clamping block 55 is extruded by the extrusion plate 43. At this time, the clamping block 55 slides inside the guide groove 54 through the rail block 56. The clamping block 55 drives the extension block 57 to extrude the second spring 58. At this time, the clamping block 55 moves to the outside of the guide groove 54. The side of the flange 7 is clamped by the clamping block 55, thereby positioning the flange 7 and making it convenient to open the flange 7. When disassembling flange 7, the electric hydraulic cylinder 3 is restarted to push the pushing assembly 6 upward, thereby pushing flange 7 upward. When the support plate 63 moves upward, the spring force of the first spring 45 will drive the clamping and positioning assembly 5 to reset upward. At this time, the clamping block 55 gradually moves away from the pressing plate 43. The second spring 58 resets the clamping block 55 until the support plate 63 is located at the top of the upright block 53. At this time, it is extremely convenient to take out flange 7. Based on the above principles, when clamping and positioning the flange 7 that needs to be punched, the device can not only automatically position the flange 7, but also assist the flange 7 in correcting its position without requiring excessive adjustment by the operator. Moreover, after the flange 7 is punched, the operator's involvement is significantly reduced during disassembly. The device automatically ejects the punched flange 7, and the operator can directly remove the flange 7 and place another punched flange 7 on the support plate 63. This operation method significantly improves the continuity of punching and is suitable for the high-efficiency production needs of large-volume flange drilling.
