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 booming development of global trade, container transportation, as a key link in the logistics field, has continued to increase in demand. Container corner fittings, as key connecting components of containers, play a vital role in the overall structural strength and safety of the containers. The quality of the circular boring holes on the container corner fittings directly affects the assembly accuracy and sealing performance of the container, and thus 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, in terms of the structural design of the processing equipment, most traditional equipment is difficult to realize the synchronous processing of multi-directional circular boring holes. 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 metal debris generated 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 accumulation of metal debris during the processing. Frequent shutdowns to clean debris reduce production efficiency, and the accumulated debris may also scratch the processing tools and hole walls, reduce the smoothness of the hole walls, and affect the processing quality of the circular boring holes of the corner fittings. In addition, in the circular hole position 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 factors such as the accuracy limitations of the external power system and the wear of the positioning device, 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 equipment for container corner fitting processing to solve the above problems. Summary of the Invention

[0015] First: The present invention adopts a linkage structure of an arc block and a double-threaded rod to realize the folding and unfolding function of the boring tool. In the initial state, the double-threaded rod is vertically retracted to the circumference of the upper circular plate, and the overall retracted diameter is adapted to the standard circular boring hole on the top of the container corner fitting, which is convenient for insertion.

[0036] Furthermore, the driving device also includes a driving shaft 46, which is fixedly connected to the output end of the motor 45, and the lower end of the driving shaft 46 is fixedly connected to an electric lifting rod 47, and the lower surface of the control seat 4 is fixedly connected to a fixed seat 48, the lower end of the driving shaft 46 passes through the upper surface of the control seat 4 and extends to the interior of the fixed seat 48, the threaded tube 2 44 is fixedly connected to the inner wall of the end of the fixed seat 48, the upper end of the threaded tube 2 44 passes through the lower end of the fixed seat 48 and extends to the interior of the fixed seat 48, the upper end of the center column 38 passes through the inner wall of the double-threaded rod 2 39 and extends to the interior of the threaded tube 2 44, the movable end of the electric lifting rod 47 passes through the upper end of the threaded tube 2 44 and extends to the interior of the threaded tube 2 44, the movable end of the electric lifting rod 47 is fixedly connected to the center column 38, and the center column 38 is fixedly connected to the movable end of the electric lifting rod 47. The center column 38 can be moved downward by turning on the electric lifting rod 47, and when the electric lifting rod 47 rotates through the motor 45 and the driving shaft 46, the center column 38 will rotate.

[0037] Furthermore, both ends of each auxiliary part 21 are slidably connected to the inner wall of the corresponding movable groove 12, and both ends of each auxiliary part 21 are rotatably connected to the inner wall of the corresponding arc rail 14. Each auxiliary part 21 matches the size of the corresponding elastic part 19. The surface of each double-threaded rod 23 is provided with a plurality of symmetrically arranged strip grooves, and the plurality of strip grooves are clamped with the inner wall of the round tube 22. Each double-threaded rod 23 is connected to the corresponding spiral knife tube 25 through a reciprocating thread transmission. Each limiting groove 26 is slidably connected to the side wall of the corresponding limiting rod 28. Each double-threaded rod 23 is connected to the corresponding threaded tube 27 through a reciprocating thread transmission. Each slide groove 31 is slidably connected to the side wall of the corresponding side long plate 33. By setting the arc rail 14, when the side bevel gear 16 drives the connecting rod 17 to rotate, the connecting rod 17 drives the auxiliary part 21 to rotate, and the auxiliary part 21 rotates with the contact point with the connecting rod 17 as the center of the circle, and the arc rail 14 provides the auxiliary part with a rotation. The rotation of 21 provides a path and support to prevent the auxiliary part 21 from shaking or deflecting when rotating, and the two ends of the auxiliary part 21 are in the movable groove 12. When the round tube 22 needs to be folded and put away, the auxiliary part 21 passively moves upward in the movable groove 12.

When the round tube 22 is to be opened for use, the two ends of the auxiliary part 21 rotate and open in the movable groove 12 while moving downward to the designated position. By setting up the spiral cutter tube 25 and cooperating with the limiting groove 26 and the limiting rod 28, when the double-threaded rod 23 rotates, the spiral cutter tube 25 can only move back and forth on the double-threaded rod 23, and will not rotate with the double-threaded rod 23. The waste generated by the boring cutter 24 during the rotational processing rotates relative to the spiral cutter tube 25. Therefore, the spiral cutter tube 25 can wrap around the waste, and the reciprocating motion of the spiral cutter tube 25 can cut the waste.

[0038] Furthermore, the upper end of the center column 38 passes through the inner wall of the annular block 30, the annular member 32 and the center bevel gear 15 and extends to the top of the center bevel gear 15. The inner walls of the center bevel gear 15 and the double-threaded rod 2 39 are both cross-grooved, and the surface of the center column 38 is cross-axis. The center bevel gear 15 and the double-threaded rod 2 39 are all slidingly connected to the center column 38 through the cross groove and the cross axis. Through the setting of the cross groove and the cross axis, when the center column 38 rotates, it can drive the center bevel gear 15 and the double-threaded rod 2 39 to rotate together. At the same time, the center column 38 can perform axial movement on the center bevel gear 15, and the double-threaded rod 2 39 can perform axial movement on the center column 38.

[0039] Furthermore, the double-threaded rod 2 39 is connected to the spiral cutter tube 2 41 through a reciprocating thread transmission, and the double-threaded rod 2 39 is connected to the threaded tube 2 44 through a reciprocating thread transmission. The bidirectional reciprocating thread transmission method is adopted, so that the boring tool 2 40 can complete bidirectional cutting motion in a single feed process.

[0040] Working principle: In the initial state, all double-threaded rods 23 are in a folded and retracted state, and their axes are arranged perpendicular to the upper circular plate 9, so that the overall diameter of the folding and boring device can pass through the standard aperture at the top of the angle piece 8. When in use, the angle piece 8 is placed on the upper surface of the placement plate 6. The self-weight of the angle piece 8 compresses the large spring 5, so that the clamping block 7 moves downward synchronously. When the clamping block 7 moves, it moves in an arc with the connecting piece on the workbench 1 as the center of the circle, and then passes 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 the external control system to move down along the support frame 2 until the lower circular plate 11 contacts the ground inside the angle piece 8, so that the placement plate 6 and the lower circular plate 11 further exert a stable clamping force on the angle piece 8, and then the electric The lifting rod 47 extends axially, pushing the center 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, and at the same time, the boring tool 2 40 is located at the upper edge of the standard hole at the top of the angle piece 8. The movable rod 37 acts on the gear 36 during the downward movement, causing the gear 36 to rotate clockwise, thereby driving the rack 34 to move upward, driving the annular block 30 to move upward, and when the annular block 30 moves upward, it will drive the connecting rod 29 to move. Because one end of the connecting rod 29 is rotatably connected to the threaded tube 1 27, when the annular block 30 moves upward, it will pass through the connecting rod 29 to open the double-threaded rod 1 23, so that the double-threaded rod 1 23 rotates with the auxiliary part 21 as the center of the circle, and at the same time, the auxiliary part 21 moves downward due to the limit 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 to open the elastic part 19, and when the auxiliary part 21 smoothly enters the elastic part 19, the small spring 20 is reset due to the elastic force, so that the elastic part 19 clamps the auxiliary part 21. At this time, the double-threaded rod 123 is opened to the horizontal state, and the boring tool 124 is located at the inner edge of the standard hole on the side of the angle piece 8. Then the motor 45 is started again to drive the drive shaft 46 to rotate. The drive shaft 46 drives the center column 38 to rotate through the electric lifting rod 47. The center column 38 drives the center bevel gear 15 to rotate. The center bevel gear 15 is engaged with the side bevel gear 16 to drive the connecting rod 17 to rotate at high speed. The connecting rod 17 drives the auxiliary part 21 to rotate through the elastic part 19, and the auxiliary part 21 drives the round tube 22 The inner wall of the round tube 22 is engaged with the strip groove of the double-threaded rod 1 23, thereby driving the double-threaded rod 1 23 to rotate. Since the double-threaded rod 1 23 is connected to the threaded tube 1 27 through a reciprocating thread, the double-threaded rod 1 23 drives the boring tool 1 24 to rotate while advancing toward the outside of the standard hole on the side of the angle piece 8, thereby boring the standard hole. After the boring tool 1 24 is pushed until it passes through the standard hole on the side of the angle piece 8 smoothly, it will return to the original path, rotating and reciprocating at the same time, so that the standard hole on the side of the angle piece 8 is thoroughly bored. While the double-threaded rod 1 23 is rotating, due to the action of the limiting groove 26 and the limiting rod 1 28, the spiral cutter tube 1 25 does not move synchronously with the double-threaded rod 1 23, but reciprocates horizontally on the double-threaded rod 1 23.The metal debris generated by the boring tool 24 during boring and the spiral cutter tube 25 are in relative rotational motion, so that the spiral cutter tube 25 can wrap around and cut the metal debris. At the same time, due to the cooperation of the cross groove and the cross shaft, the center column 38 will drive the double-threaded rod 2 39 to rotate synchronously, driving the boring tool 2 40 to perform reciprocating motion while performing vertical deep hole processing. The sliding of the limit rod 2 43 and the straight rail 42 ensures that the spiral cutter tube 2 41 reciprocates axially on the double-threaded rod 2 39 when the double-threaded rod 2 39 rotates, and wraps and cuts the waste generated by the boring tool 2 40 during work. All components work together to complete the one-time forming processing of the multi-dimensional boring of the corner piece 8. After the processing is completed, the double-threaded rod 1 23 is inside the angle piece 8, and the motor 45 is turned off when moving. At this time, the elastic piece 19 is the same as the initial state, with the opening facing upward. Then the electric lifting rod 47 is started to shrink. When shrinking, it will drive the center column 38 to move upward. Due to the arrangement of the cross groove and the cross shaft, the center column 38 moves upward in the center bevel gear 15 without driving the center bevel gear 15 to move together. The center column 38 drives the movable rod 37 to move upward. The upward movement of the movable rod 37 will prompt the gear 36 to rotate counterclockwise, causing the rack 34 to move downward. The rack 34 drives the annular block 30 to move downward. The annular block 30 drives the double-threaded rod 23 to make an arc motion with the auxiliary piece 21 as the center through the connecting rod 29. Because the auxiliary piece 21 is in the movable position, The auxiliary part 21 first drives the double-threaded rod 23 to move downward in an arc shape, and then the auxiliary part 21 moves upward in the movable groove 12 and disengages from the elastic part 19. The auxiliary part 21 rotates while moving upward in the movable groove 12, so that the double-threaded rod 23 moves upward while moving in an arc shape with the auxiliary part 21 as the center, thereby gradually approaching the arc block 10 to achieve the purpose of folding and retracting. After all the double-threaded rods 23 are retracted, the control seat 4 is moved upward through the external control system. At this time, because all the double-threaded rods 23 have reached the minimum angle, the rise 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, and the electric lifting rod 47 and the fixed seat 48 will rise together. The lowering rod 47 drives the center column 38 upward, and the center column 38 drives the second threaded tube 44, the second boring tool 40, and the second spiral cutter tube 41 upward. When the center column 38 moves upward, it will drive the annular block 30 upward through the movable rod 37, the gear 36, and the rack 34 until the annular block 30 contacts the annular member 32. Because the annular member 32 is fixed in the arc block 10, it will drive the arc block 10 upward, that is, the entire folding boring device upward, through the already machined hole at the top of the angle piece 8, out of the angle piece 8, and then pick up the angle piece 8, so that the large spring 5 resets, the clamping block 7 releases the clamping of the angle piece 8, and then a new angle piece 8 to be bored is placed, and processing can continue.
