Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a boring device used for processing container corner pieces. Background Art

[0002] With the vigorous development of global trade, container transportation, as a key link in the logistics field, has seen a continuous increase in demand. Container corner fittings, as key connecting components of containers, play a vital role in the overall structural strength and safety of containers. The processing quality of the circular boring holes on the container corner fittings directly affects the assembly accuracy and sealing performance of the container, and thus is related to the safety and reliability of cargo transportation.

[0003] In the existing container corner circular boring processing technology, there are many problems that need to be solved urgently. First of all, in terms of the structural design of processing equipment, most traditional equipment is difficult to achieve synchronous processing of circular boring holes in multiple directions. Usually, circular boring holes in different directions need to be processed separately, which not only increases the processing steps and time costs and reduces production efficiency, but also easily leads to the accumulation of processing errors due to multiple clamping and positioning, affecting the relative position accuracy between the circular boring holes of the corner pieces, and thus affecting the overall assembly quality of the container. Secondly, in the circular boring processing process, the accumulation of metal debris is a common problem. As the processing proceeds, if the generated metal debris cannot be removed in time and effectively, it is very easy to accumulate in the circular channel, causing the channel to be blocked, which will not only seriously affect the continuity of the processing, but also lead to the processing process. Frequent shutdowns to clean up debris reduce production efficiency, and the accumulated debris may also scratch the processing tool and the hole wall, reduce the smoothness of the hole wall, and affect the processing quality of the circular boring of the corner fittings. In addition, in the circular hole alignment link of the container corner fittings, the existing technology often relies on complex external power systems and precise positioning devices to achieve the alignment of the corner fittings and the processing devices. This alignment method not only increases the complexity and manufacturing cost of the equipment, but also in the actual operation process, due to the accuracy limitations of the external power system and the wear of the positioning device and other factors, it is difficult to ensure that the axis of the circular boring hole of the corner fitting and the processing device are always accurately aligned, and centering deviations are prone to occur, resulting in inaccurate positions of the processed circular boring holes, affecting the normal use of the container corner fittings. To this end, we propose a boring device for container corner fitting processing to solve the above problems. Summary of the invention

[0014] The present invention provides a boring equipment for processing container corner fittings through improvement. Compared with the prior art, it has the following improvements and advantages: First: The present invention adopts an arc-shaped block and a first double threaded rod linkage structure to realize the folding and unfolding function of the first boring tool. In the initial state, the first double threaded rod is vertically retracted around the upper circular plate, and the overall retracted diameter adapts to the standard circular boring hole at the top of the container corner fitting, facilitating penetration. During processing, the electric lifting rod presses down to drive the central column, and through the cooperation of the connecting rod and the first threaded pipe, the first double threaded rod rotates and unfolds to the horizontal position, accurately aligning with the circular hole on the side wall of the corner fitting.

This dual waste treatment mechanism effectively avoids the blockage of circular channels, significantly improving the processing continuity and the smoothness of the hole wall.

[0016] Third: Regarding the circular hole alignment requirement of the container corner fitting in the present invention, the clamping device adopts a composite design of a large spring and symmetric clamping blocks. When the corner fitting is placed on the placement plate, its own weight compresses the large spring to generate a downward displacement, and through the four-bar linkage mechanism, two groups of clamping blocks are driven to rotate synchronously towards the center, realizing the automatic locking of the workpiece. This gravity-triggered mechanism requires no external power, ensuring the accurate alignment of the circular boring axis of the corner fitting with the processing device for rapid positioning and processing.

[0020] The present invention provides a boring equipment for processing container corner fittings by improvement. The technical solution of the present invention is as follows: As Figure 1 - Figure 10 As shown, a boring equipment for processing container corner fittings includes a workbench 1.

[0021] Furthermore, the control seat 4 is slidably connected to the inner wall of the support frame 2.

Through the rotatably connected clamping blocks 7, the automatic centering and locking of the clamping blocks 7 can be achieved by their own weight when the corner fittings 8 are placed. With the elastic support of the large spring 5, it not only ensures the positioning stability of the corner fittings 8 but also avoids surface damage caused by rigid clamping. The corner fittings 8 are standard corner fittings for containers, with the main body being a cast steel part, and standardized circular boring holes for lifting and fixing are provided at the four corners.

[0023] Furthermore, the folding boring device further includes a plurality of symmetrically arranged arc-shaped blocks 10. Each arc-shaped block 10 is fixedly connected to the lower end of the upper circular plate 9. The lower ends of the plurality of arc-shaped blocks 10 are fixedly connected to the same lower circular plate 11. Activity grooves 12 are formed on both sides of each arc-shaped block 10. The side walls of every two adjacent arc-shaped blocks 10 are fixedly connected to the same rectangular plate 13. The lower ends of every two adjacent arc-shaped blocks 10 are fixedly connected to the same arc-shaped rail 14. A central bevel gear 15 is arranged below the upper circular plate 9. A plurality of symmetrically arranged side bevel gears 16 are meshed with the surface of the central bevel gear 15. One end of each side bevel gear 16 away from the central bevel gear 15 is fixedly connected to a connecting rod 17. One end of each connecting rod 17 away from the side bevel gear 16 penetrates through the side wall of the corresponding rectangular plate 13 and extends to the other side of the rectangular plate 13. Fixing grooves 18 are formed on the surface of each connecting rod 17. Elastic members 19 are arranged in each fixing groove 18. The lower half of each elastic member 19 is fixedly connected to the inner wall of the corresponding fixing groove 18. Two symmetrically arranged small springs 20 are fixedly connected to the surface of each elastic member 19. One end of each small spring 20 away from the elastic member 19 is fixedly connected to the inner wall of the fixing groove 18. Auxiliary members 21 are arranged in each elastic member 19. A circular tube 22 is fixedly connected to the side wall of each auxiliary member 21. A first double threaded rod 23 is arranged inside each circular tube 22. One end of each first double threaded rod 23 away from the circular tube 22 is fixedly connected to a first boring tool 24. A first spiral cutter tube 25 is sleeved on the surface of each first double threaded rod 23. A limiting groove 26 is formed on the surface of each first spiral cutter tube 25. A first threaded tube 27 is sleeved on the surface of each first double threaded rod 23. One end of each first threaded tube 27 close to the first spiral cutter tube 25 is fixedly connected to a limiting rod 28. A connecting rod 29 is rotatably connected to the inner wall of each first threaded tube 27. Through the meshing and linkage of the central bevel gear 15 and multiple groups of side bevel gears 16, and with the guiding action of the activity grooves 12 and the arc-shaped rails 14, the rotation of the side bevel gears 16 enables the first double threaded rod 23 to drive the rotation of the first boring tool 24, ensuring the synchronization and consistency of multi-hole processing.

[0024] Furthermore, the side walls of multiple connecting rods 29 are rotatably connected to the same annular block 30. Multiple symmetrically arranged sliding grooves 31 are formed on the surface of the annular block 30. The inner walls of multiple arc-shaped blocks 10 are fixedly connected to the same annular member 32. The inner wall of each arc-shaped block 10 is fixedly connected to a side long plate 33. The side wall of each side long plate 33 is slidably connected to a rack 34. Multiple racks 34 are fixedly connected to the lower end of the annular block 30. The inner wall of each arc-shaped block 10 is fixedly connected to a support member 35. A gear 36 is rotatably connected to the inner wall of each support member 35. Each rack 34 is meshed with the surface of the corresponding gear 36. Each gear 36 is meshed with the same movable rod 37. The upper end of the movable rod 37 is fixedly connected to a central column 38. A second double-threaded rod 39 is sleeved on the surface of the central column 38. A second boring tool 40 is fixedly connected to the surface of the second double-threaded rod 39. A second spiral cutter tube 41 is sleeved on the surface of the second double-threaded rod 39. A straight rail 42 is fixedly connected to the surface of the second spiral cutter tube 41. A second limiting rod 43 is slidably connected to the inner wall of the straight rail 42. A second threaded tube 44 is sleeved on the surface of the second double-threaded rod 39. The meshing of the movable rod 37 and the gear 36 enables the movable rod 37 to drive the gear 36 to rotate when axially moving. When the electric lifting rod 47 pushes the central column 38 downward and the movable rod 37 axially moves accordingly, its axial pressure is precisely transmitted to the gear 36 through the meshing transmission of the rack 34 and the gear 36, thereby driving the annular block 30 to move upward along the sliding groove 31, driving the connecting rod 29 to push the first threaded tube 27 to extend outward, and realizing the unfolding action of the first double-threaded rod 23.

[0025] Furthermore, the driving device further includes a driving shaft 46. The driving shaft 46 is fixedly connected to the output end of the motor 45. The lower end of the driving shaft 46 is fixedly connected to an electric lifting rod 47. The lower surface of the control seat 4 is fixedly connected to a fixed seat 48. The lower end of the driving shaft 46 penetrates the upper surface of the control seat 4 and extends into the interior of the fixed seat 48. The second threaded tube 44 is fixedly connected to the inner wall of the end of the fixed seat 48. The upper end of the second threaded tube 44 penetrates the lower end of the fixed seat 48 and extends into the interior of the fixed seat 48. The upper end of the central column 38 penetrates the inner wall of the second double-threaded rod 39 and extends into the interior of the second threaded tube 44. The movable end of the electric lifting rod 47 penetrates the upper end of the second threaded tube 44 and extends into the interior of the second threaded tube 44. The movable end of the electric lifting rod 47 is fixedly connected to the central column 38. The central column 38 is fixedly connected to the movable end of the electric lifting rod 47. By turning on the electric lifting rod 47, the central column 38 can be moved downward. When the electric lifting rod 47 rotates through the motor 45 and the driving shaft 46, the central column 38 will rotate.

[0026] Furthermore, both ends of each auxiliary member 21 are slidably connected to the inner wall of the corresponding movable slot 12, both ends of each auxiliary member 21 are rotatably connected to the inner wall of the corresponding arc-shaped rail 14, each auxiliary member 21 is dimensionally matched with the corresponding elastic member 19, a plurality of symmetrically arranged strip-shaped grooves are formed on the surface of each double threaded rod 23, and the plurality of strip-shaped grooves are engaged with the inner wall of the circular tube 22. Each double threaded rod 23 is connected to the corresponding first spiral cutter tube 25 through reciprocating thread transmission. Each limiting slot 26 is slidably connected to the side wall of the corresponding first limiting rod 28. Each double threaded rod 23 is connected to the corresponding first threaded tube 27 through reciprocating thread transmission. Each sliding slot 31 is slidably connected to the side wall of the corresponding side long plate 33. By providing the arc-shaped rail 14, when the side bevel gear 16 drives the connecting rod 17 to rotate, the connecting rod 17 drives the auxiliary member 21 to rotate. The auxiliary member 21 rotates with the contact point with the connecting rod 17 as the center, and the arc-shaped rail 14 provides a path and support for the rotation of the auxiliary member 21 to prevent the auxiliary member 21 from shaking or shifting during rotation. The two ends of the auxiliary member 21 are in the movable slot 12. When the circular tube 22 needs to be folded and retracted, the auxiliary member 21 is passively moved upward in the movable slot 12. When it reaches the top of the movable slot 12, it rotates so that the circular tube 22 can be smoothly folded and retracted. When the circular tube 22 is to be opened for use, while the two ends of the auxiliary member 21 rotate and open in the movable slot 12, they move downward to the designated position. By providing the first spiral cutter tube 25, through the cooperation of the limiting slot 26 and the first limiting rod 28, when the double threaded rod 23 rotates, the first spiral cutter tube 25 can only move reciprocally on the double threaded rod 23 and will not rotate with the double threaded rod 23. The waste generated during the rotary machining of the first boring tool 24 rotates relative to the first spiral cutter tube 25. Therefore, the first spiral cutter tube 25 can wind the waste, and the reciprocating movement of the first spiral cutter tube 25 can cut the waste.

[0027] Furthermore, the upper end of the central column 38 penetrates through the inner walls of the annular block 30, the annular member 32 and the central bevel gear 15 and extends above the central bevel gear 15. The inner walls of both the central bevel gear 15 and the double threaded rod 39 are provided with cross grooves, and the surface of the central column 38 is provided with a cross shaft. The central bevel gear 15 and the double threaded rod 39 are slidably connected to the central column 38 through the cross grooves and the cross shaft. Through the setting of the cross grooves and the cross shaft, when the central column 38 rotates, it can drive the central bevel gear 15 and the double threaded rod 39 to rotate together. At the same time, the central column 38 can perform axial movement on the central bevel gear 15, and the double threaded rod 39 can perform axial movement on the central column 38.

[0028] Furthermore, the double threaded rod II 39 is connected to the spiral cutter tube II 41 through reciprocating screw drive, and the double threaded rod II 39 is connected to the threaded tube II 44 through reciprocating screw drive. The double reciprocating screw drive mode enables the boring cutter II 40 to complete the bidirectional cutting motion during a single feed process.

[0029] Working principle: In the initial state, all double threaded rods 23 are in a folded and retracted state, and their axes are perpendicular to the upper circular plate 9, so that the overall diameter of the folding boring device can pass through the standard hole diameter at the top of the angle piece 8. When in use, place the angle piece 8 on the upper surface of the placement plate 6. The self-weight of the angle piece 8 compresses the large spring 5, causing the clamping blocks 7 to move downward synchronously. When the clamping blocks 7 move, they perform an arc-shaped movement with the connecting piece on the workbench 1 as the center, and then through the connecting piece on the placement plate 6, so that all the clamping blocks 7 clamp the angle piece 8. Subsequently, the control seat 4 is driven by an external control system to move downward along the support frame 2 until the lower circular plate 11 contacts the inner ground of the angle piece 8, so that the placement plate 6 and the lower circular plate 11 further provide a stable clamping force on the angle piece 8. Then, start the electric lifting rod 47 to extend axially, pushing the central column 38 to move downward synchronously, so that the bottom end of the movable rod 37 presses against the lower circular plate 11 to form a rigid support. At the same time, the boring tool two 40 is located above the edge of the standard hole at the top of the angle piece 8. During the downward movement of the movable rod 37, it acts on the gear 36, causing the gear 36 to rotate clockwise, thereby driving the rack 34 to move upward, driving the annular block 30 to move upward. When the annular block 30 moves upward, it will drive the connecting rod 29 to move. Since one end of the connecting rod 29 is rotatably connected to the threaded pipe one 27, when the annular block 30 moves upward, it will open the double threaded rod one 23 through the connecting rod 29, causing the double threaded rod one 23 to rotate with the auxiliary part 21 as the center. At the same time, the auxiliary part 21 moves downward due to the limitation of the movable groove 12 until the auxiliary part 21 is stuck into the elastic part 19. During the insertion process, the auxiliary part 21 squeezes the two small springs 20, causing the elastic part 19 to open. After the auxiliary part 21 smoothly enters the elastic part 19, the small springs 20 reset due to the elastic force, so that the elastic part 19 clamps the auxiliary part 21. At this time, the double threaded rod one 23 is opened to a horizontal state, and the boring tool one 24 is located at the inner edge of the standard hole on the circumferential side of the angle piece 8. Then, start the motor 45 to drive the drive shaft 46 to rotate. The drive shaft 46 drives the central column 38 to rotate through the electric lifting rod 47. The central column 38 drives the central bevel gear 15 to rotate. The central bevel gear 15 meshes with the side bevel gear 16 to drive the connecting rod 17 to rotate at a high speed. The connecting rod 17 drives the auxiliary part 21 to rotate through the elastic part 19. The auxiliary part 21 drives the circular tube 22 to rotate. The inner wall of the circular tube 22 drives the double threaded rod one 23 to rotate because it is clamped with the strip-shaped groove of the double threaded rod one 23. And because the double threaded rod one 23 and the threaded pipe one 27 are connected by a reciprocating thread, the double threaded rod one 23 drives the boring tool one 24 to rotate and advance toward the outer side of the standard hole on the circumferential side of the angle piece 8, so as to bore the standard hole. After the boring tool one 24 is advanced to smoothly pass through the standard hole on the circumferential side of the angle piece 8, it will return along the original path. In this way, while rotating and reciprocating, the standard hole on the circumferential side of the angle piece 8 is completely bored. While the double threaded rod one 23 is rotating, due to the action of the limiting groove 26 and the limiting rod one 28, the spiral cutter tube one 25 will not move synchronously with the double threaded rod one 23, but move horizontally back and forth on the double threaded rod one 23.When the boring tool 1-24 bores a hole, the metal chips generated are in a relative rotational motion with the spiral tool tube 1-25. As a result, the spiral tool tube 1-25 can wind and cut the metal chips. At the same time, due to the cooperation of the cross groove and the cross shaft, the central column 38 will drive the double threaded rod 2-39 to rotate synchronously, driving the boring tool 2-40 to perform reciprocating motion while carrying out vertical deep hole machining. The sliding of the limiting rod 2-43 on the straight rail 42 ensures that when the double threaded rod 2-39 rotates, the spiral tool tube 2-41 moves axially back and forth on the double threaded rod 2-39, winding and cutting the waste generated during the operation of the boring tool 2-40. Each component works together to complete the one-time forming machining of multi-dimensional boring of the angle piece 8. After the machining is completed, when the double threaded rod 1-23 moves towards the inside of the angle piece 8, the motor 45 is turned off. At this time, the elastic member 19 is in the initial state with the opening facing upwards. Then, the electric lifting rod 47 is started to contract. When contracting, it will drive the central column 38 to move upwards. Due to the setting of the cross groove and the cross shaft, the central column 38 moves upwards within the central bevel gear 15 without driving the central bevel gear 15 to move together. The central column 38 drives the movable rod 37 to move upwards. The upward movement of the movable rod 37 will cause the gear 36 to rotate counterclockwise, making the rack 34 move downwards. The rack 34 drives the annular block 30 to move downwards. The annular block 30 drives the double threaded rod 1-23 to perform an arc-shaped movement with the auxiliary member 21 as the center through the connecting rod 29. Also, because the auxiliary member 21 is in the movable groove 12, the auxiliary member 21 first drives the double threaded rod 1-23 to perform a downward arc-shaped movement, and then the auxiliary member 21 moves upwards within the movable groove 12 and disengages from the elastic member 19. The auxiliary member 21 rotates while moving upwards within the movable groove 12, causing the double threaded rod 1-23 to perform an arc-shaped movement with the auxiliary member 21 as the center and move upwards at the same time, thus gradually approaching the arc-shaped block 10 to achieve the purpose of folding and retracting. After all the double threaded rods 1-23 are retracted, the control seat 4 is moved upwards through the external control system. At this time, since all the double threaded rods 1-23 have been received at the minimum angle, the upward movement of the control seat 4 will drive the motor 45, the drive shaft 46, the electric lifting rod 47, and the fixed seat 48 to rise together. The electric lifting rod 47 drives the central column 38 to move upwards, and the central column 38 drives the threaded tube 2-44, the boring tool 2-40, and the spiral tool tube 2-41 to move upwards. When the central column 38 moves upwards, it will drive the annular block 30 to move upwards together through the movable rod 37, the gear 36, and the rack 34. When the annular block 30 contacts the annular member 32, and since the annular member 32 is fixed within the arc-shaped block 10, it will drive the arc-shaped block 10 to move upwards together, that is, drive the entire folding boring device to move upwards. Through the hole that has been machined at the top of the angle piece 8, it leaves the inside of the angle piece 8. Then, the angle piece 8 is picked up, the large spring 5 is reset, the clamp block 7 releases the clamping of the angle piece 8, and then a new angle piece 8 to be bored is placed and the machining can continue.,
