Description

Technical Field

[0001] The present invention relates to the technical field of civil air defense door production, and more particularly to an automatic docking tooling for the production of civil air defense door frames. Background Art

[0002] Civil air defense doors are thick and heavy, weighing several tons, and usually open outwards to resist shock wave pressure.

[0003] The door frame is embedded in the wall and is tightly connected to the building structure to ensure overall stability. In wartime, it can resist air raids, nuclear, biological and chemical weapons, and provide refuge space. Civil air defense doors are a safety barrier that combines protection, sealing and durability, and are a key component of the urban underground space protection system. Existing application documents, such as application number CN202310154095.1, entitled "A civil air defense door tooling and a civil air defense door manufacturing process," have the following functions: a fixing component 2 is used to fix the crossbeam or longitudinal beam on the assembly plate 1. A pushing component 3 is used to push the crossbeam or longitudinal beam into contact with each other. A rotating component 4 is used to adjust the angle between the crossbeam and the longitudinal beam. Although the above functions achieve the purpose of accurately docking the workpiece, they have the following defects: 1. Due to the structural limitations in the cited documents, it can only dock and fix two side beams at the same time. Since the standard civil air defense door frame is rectangular, it is not possible to dock a complete door frame at one time; 2. The loading operation cannot be performed efficiently in the cited documents, and manual loading operations are required frequently, resulting in poor work efficiency; 3. The production of civil air defense doors is based on the national standard (reference RFJ 01-2015). The length-to-width ratio of conventional civil air defense doors is 2:1~3:1. Most of their frames are standard rectangles, and the angle between the edge and the adjacent edge is 90 degrees.

In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention.

The translation portion 3 includes a V-shaped groove 5 and a connecting component 6. The workpiece 1 is located in the V-shaped groove 5. The translation portion 3 drives the workpiece 1 to move intermittently in the horizontal plane. The flipping portion 4 includes a magnetic attraction component 7. The flipping portion 4 drives the workpiece 1 to move in an arc in the vertical direction through the magnetic attraction component 7.

There are at least two fixing points between the connecting plate 21 and the chain 16. The V-groove 5 is installed on the upper end of the connecting plate 21, and the V-groove 5 opens upward, and the workpiece 1 opens upward.

[0021] Specifically in actual application, the workpiece 1 is manually placed in the V-groove 5, and then the rotating motor 17 is controlled to rotate. The rotation of the rotating motor 17 drives the pulley 18 to rotate. The rotation of pulley 18 drives pulley 2 19 to rotate through the transmission belt 20. The rotation of pulley 2 19 drives the rotating shaft 14 and the sprocket 15 to rotate. The sprocket 15 drives the two chains 16 to rotate synchronously. There are at least two fixed points between the connecting plate 21 and the chain 16. The connecting plate 21 is in a stable moving state, and the V-groove 5 on the connecting plate 21 is also in a stable state. The rotating shaft 14 is in a stable state through the action of bearing 13. In this embodiment, the workpiece 1 is in the shape of an angle steel with its opening facing upward.

[0022] Reference Figure 1、 Figure 2 and Figure 3 The flipping part 4 includes a support rod 22 installed on one side of the workbench 2. The support rod 22 is provided with multiple pairs. A bearing 23 is installed on the upper end of the support rod 22. A long shaft 24 is installed on the inner ring of the bearing 23. A gear 25 is installed at one end of the long shaft 24. A stepper motor 26 is installed on the support rod 22. A gear 27 meshing with the gear 25 is installed at the rotating end of the stepper motor 26. A swing rod 28 is installed on the long shaft 24. The magnetic attraction component 7 is installed at one end of the swing rod 28. The magnetic attraction component 7 is a positive V-shaped electromagnet 29. A trapezoidal bearing block 30 is installed on one side of the workbench 2. One end of the trapezoidal bearing block 30 is hinged to the workbench 2. The upper end of the trapezoidal bearing block 30 is flush with the workbench 2. A tension spring 31 is installed between the trapezoidal bearing block 30 and the workbench 2.

[0023] Specifically in actual applications, in the initial state, the positive V-shaped electromagnet 29 is in contact with the workpiece 1, and the positive V-shaped electromagnet 29 is controlled to be energized and adsorb the workpiece 1. When the stepper motor 26 rotates, it drives the long shaft 24 to rotate, and the rotation of the long shaft 24 drives gear 2 27 to rotate, and gear 2 27 drives gear 1 25 to rotate. The rotation of gear 1 25 drives the long shaft 24 to rotate, and through the action of bearing 2 23, the long shaft 24 rotates stably, and finally the long shaft 24 drives the swing rod 28 and the workpiece 1 to rotate upward. Since the trapezoidal supporting block 30 is in an interfering state with the workpiece 1, the workpiece 1 must be lifted to a position higher than the trapezoidal supporting block 30 until it is separated from the trapezoidal supporting block 30. At this time, the trapezoidal supporting block 30 is in a horizontal state under the action of the tension spring 1 31. At this time, the stepper motor 26 is controlled to rotate in the opposite direction until the workpiece 1 is placed on the trapezoidal supporting block 30.

[0024] Reference Figure 1 、 Figure 2 and Figure 5 The magnetic attraction component 7 is an inverted V-shaped electromagnet 57.

[0025] Specifically in practical applications, in this embodiment, the shape of the magnetic attraction component 7 can be changed according to the actual situation according to the different shapes of the workpiece 1. If the workpiece is square, the magnetic attraction component 7 can be set as an inverted V-shaped electromagnet 57 to facilitate the movement of the workpiece 1.

[0026] Reference Figure 1 and Figure 4 The driving part 8 includes a driving motor 32 installed in the workbench 2. A square column 33 is installed at the rotating end of the driving motor 32. A threaded column 34 is provided at one end of the square column 33. A nut 35 is installed on the threaded column 34. The center of the driving wheel 10 is square. The driving wheel 10 is inserted into the square column 33. An annular groove 36 is opened on the outside of the driving wheel 10, and a steel wire rope 37 is installed in the annular groove 36.

[0027] Specifically in actual application, the rotation of a drive motor 32 can drive the actuator 9 around the workbench 2 to move. The movement of the actuator 9 relies on the rotation of the drive motor 32 to provide power. When the drive motor 32 rotates forward, it drives the driving wheel 10 to rotate, and the driving wheel 10 drives the wire rope 37. The other end of the wire rope 37 pulls the actuator 9 to move. The driving wheel 10 is in a stable state through the action of the nut 35. Figure 1 As shown, the size of the driving wheel 10 can be manually changed through the opening on the lower surface of the workbench 2. In this embodiment, the driving wheel that drives the execution parts 9 on both sides to move is set to a larger diameter. During actual operation, the workpieces on both sides of the workbench 2 are first moved to the designated positions on the workbench 2, and the wire rope 37 is stored in the annular groove 36 through the action of the annular groove 36.

[0028] Reference Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 8 The execution part 9 includes a strip opening 38 opened on the upper surface of the workbench 2. There are four pairs of strip openings 38 distributed around the workbench 2. There are slide grooves 39 on both sides of the strip opening 38. A sliding block 40 is installed in the slide groove 39. A metal plate 58 is installed at one end of the sliding block 40. A notch 41 is opened at one end of the metal plate 58. The trapezoidal block 11 is installed in the notch 41. The trapezoidal block 11 is hinged to the notch 41. A baffle 42 is installed at the lower end of the trapezoidal block 11. A torsion spring 43 is installed between the trapezoidal block 11 and the connecting plate 21. The torsion spring 43 drives the trapezoidal block 11 It has a tendency to rotate upward. A horizontal plate 44 is installed at the lower end of the sliding block 40. The horizontal plate 44 connects the adjacent sliding blocks 40. An L-shaped plate 45 is installed at one end of the horizontal plate 44. A circular hole 46 is opened at one end of the L-shaped plate 45. A sliding column 47 is provided in the circular hole 46. Limiting plates 48 are installed at both ends of the sliding column 47. A compression spring 49 is installed between the sliding column 47 and the L-shaped plate 45. A tension spring 50 is installed between the L-shaped plate 45 and the workbench 2. One end of the wire rope 37 is fixedly connected to the sliding column 47, and the other end of the wire rope 37 is fixedly connected to the driving wheel 10.

[0029] In this embodiment, the size of the workpiece 1 is determined before work, and then the limit column 54 is placed to the corresponding size. There are four pairs of strip openings 38, and they are respectively set at the positions around the workbench 2. When the wire rope 37 pulls the sliding column 47, the sliding column 47 directly drives the cross plate 44 to move toward the center of the workbench 2 through the elastic force of the compression spring 2 49. The cross plate 44 connects the two sliding blocks 40 at different positions. The elastic force of the compression spring 2 49 is greater than the elastic force of the tension spring 2 50. At this time, the compression spring 2 49 does not deform, and the sliding block 40 and the metal plate 58 are stably moved by the action of the slide groove 39. When the metal plate 58 moves, it drives The trapezoidal block 11 moves, and the movement of the trapezoidal block 11 drives the workpiece 1 to move to the position of the limit column 54; after the workpieces 1 on both sides of the workbench 2 are moved into place, the workpieces 1 on the other two sides still need to be moved, and the drive motor 32 needs to continue to rotate. In order to prevent the workpieces 1 on both sides from being stuck with the trapezoidal block 11, a sliding column 47 and a second compression spring 49 are provided. As the drive motor 32 rotates, the tension of the wire rope 37 is greater than the elastic force of the second compression spring 49, and the second compression spring 49 is in a slowly compressed state until the workpieces 1 on the other two sides move to the specified position; the above operation method is based on the same length of the wire rope 37 and the same moving distance of the workpiece 1; Alternatively, different lengths of steel wire ropes 37 or different moving distances of different workpieces 1 may be provided to avoid compression of the second compression spring 49 . In this case, the sliding column 47 and the second compression spring 49 only play a buffering role.

Positioning plates 55 are installed on both sides of the limit column 54. The positioning plates 55 are stuck in the limit groove 52.

[0031] Specifically in practical applications, the limit assembly 51 can be used to limit the position where the workpiece 1 stops moving, and can be used as a fixed point for the guide plate 56. When set as the fixed point for the guide plate 56, the guide plate 56 needs to be fixed to the limit column 54, and the limit column 54 is manually held and inserted into the limit groove 52. At the same time, the positioning plate 55 is aligned with the limit groove 52. It is in a fixed state in the horizontal direction. By setting the positioning ports 53 at different positions, the purpose of manual adjustment is achieved.

The guide plates 56 are fixedly connected to the workbench 2 through the limiting assembly 51. The extending direction of the guide plates 56 is perpendicular to the extending direction of the limiting groove 52.

[0033] Specifically in practical applications, the workpiece 1 can be moved to the designated position more accurately through the action of the guide plate 56 and the limiting column 54. Figure 2 As shown, the extension direction of the guide plate 56 is perpendicular to the extension direction of the limiting groove 52.

[0034] Reference Figure 1 and Figure 4 , the diameter of the threaded column 34 is greater than the diameter of the square column 33.

[0035] Specifically, in practical applications, the driving wheel 10 is fixed by tightening the threaded column 34 , which is also convenient for manual replacement later.
