Description

Technical Field

[0001] The invention belongs to the technical field of rolling, in particular to a novel rolling hole processing method. Background Art

[0002] Rolling cutters can utilize the plastic deformation of metal at room temperature to flatten the microscopic unevenness of the workpiece surface, thereby achieving the purpose of changing the surface structure, mechanical properties, shape and size. No matter what kind of metal processing tool is used, there will always be tiny uneven tool marks left on the surface of the part, and there will be staggered and undulating peaks and valleys. Rolling cutters are a mechanical non-cutting plastic processing method that utilizes the principle of mechanical extrusion to obtain a mirror-like smooth metal surface.

[0003] The traditional process of processing mirror holes, because the wall thickness is less than 1mm, turning or milling, all use the method of high speed and low feed. Although batch processing of CNC machines is achieved, the production efficiency is extremely low, the dependence on imported tools is strong, and the processing cycle is long;

[0004] At the same time, after the existing rolling cutter head has been used for a period of time, its cutter head will be deformed due to long-term grinding. Therefore, the staff is required to observe it from time to time and replace the rolling cutter head in time. However, the existing rolling cutter head is threadedly fixed to the positioning head. When disassembling it, the entire equipment needs to be shut down, and then the staff needs to disassemble and replace it. The process is cumbersome and the replacement efficiency is low, which leads to the problem of low efficiency in rolling hole processing.

[0005] To this end, the present invention provides a novel rolling hole processing method. Summary of the invention

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] Embodiment 1: Figures 1 to 6 As shown, a novel rolling hole processing method according to an embodiment of the present invention comprises the following specific steps:

[0038] Preparation: Prepare the rolling hole processing equipment, which includes a body 1. First, fix the parts to be rolled using a triangular chuck 2, and install a rolling cutter 5. The new rolling cutter 5 is mainly composed of an artificial synthetic diamond inlaid ball, and the diamond ball is rolled with the workpiece surface;

[0039] Operation and processing: Start the screw on the surface of the machine body 1 to drive the rolling cutter 5 to approach the part. After approaching the part, start the first guide block 4 at the bottom of the rolling cutter 5. The first guide block 4 drives the rolling cutter 5 to slowly feed along the first guide rail 3 to grind the inner wall of the hole on the surface of the part;

[0040] End: Grinding is completed, the first guide block 4 withdraws the part with the rolling cutter 5, and then the part is removed from the triangular chuck 2, and a new part is fixed again for grinding.

[0041] like Figures 1 to 6 As shown, a triangular chuck 2 is fixedly connected to one side of the machine body 1 of the present embodiment, a first guide rail 3 is slidably provided on the upper surface of the machine body 1, a first guide block 4 is slidably connected to the upper surface of the first guide rail 3, a first motor 41 is fixedly connected to the upper surface of the first guide block 4, a positioning head 417 is fixedly connected to the output end of the first motor 41, a rolling knife 5 is fixedly connected to one side of the positioning head 417, a top-disassembly assembly is provided on the first guide block 4, the top-disassembly assembly includes a second motor 42 fixedly connected to one side of the positioning head 417, a limiting ring 45 is slidably provided at the output end of the second motor 42, and the limiting ring 45 is used for disassembling and installing the rolling knife 5; a second guide block 6 is also slidably connected to the first guide rail 3, a lifting assembly is provided on the upper surface of the second guide block 6, the lifting assembly includes a new rolling knife 5 placed on the upper surface of the second guide block 6, a lifting assembly is provided between the first guide block 4 and the second guide block 6, and the lifting assembly is used to collect the rolling knife 5 at the same time during the dismantling process and can supply a new rolling knife 5.

[0042] Specifically, after the existing roller cutter head has been used for a period of time, its cutter head will be deformed due to long-term grinding, so the staff needs to observe it irregularly and replace the roller cutter head 5 in time. However, the existing roller cutter head 5 is threadedly fixed on the positioning head 417. When disassembling, the entire equipment needs to be shut down, and then the staff needs to disassemble and replace it. The process is cumbersome and the replacement efficiency is low, which leads to the problem of low efficiency of rolling hole processing.

[0043] Therefore, the present invention solves this problem by setting a certain structure. First, the part to be ground is fixed by the triangular chuck 2. After the triangular chuck 2 fixes the part, several screws on one side of the machine body 1 are started, as shown in the attached Figure 1 As shown in the figure, several screw rods will simultaneously drive the first guide rail 3 to approach the triangular chuck 2, which can drive the first guide block 4 on the first guide rail 3. The upper surface of the first guide block 4 is fixed with a rolling cutter 5. When the rolling cutter 5 is aligned with the part, the first motor 41 on the first guide block 4 is started to drive the positioning head 417 to rotate, so as to face the circular hole on the surface of the part, and then the first guide rail 3 is started again, and the first guide rail 3 will drive the rolling cutter 5 to insert into the hole inside the part, and then the diamond ball on one side of the rolling cutter 5 will abut against the inner wall of the hole, and then the built-in motor of the body 1 is started to drive the triangular chuck 2 to rotate, and then the rolling cutter 5 grinds the inner wall of the part hole by slowly feeding the cutter, thereby forming a mirror hole, and this operation is continuously repeated to grind the part, but when the rolling cutter 5 has been used for a certain period of time, it needs to be fed in. To replace the cutter head, the first motor 41 is rotated to drive the positioning head 417 and the rolling cutter 5 to reset to be parallel to the first guide rail 3, and then the second guide block 6 at the other end of the first guide rail 3 is started, and the second motor 42 on the first guide block 4 is started at the same time. The second motor 42 will drive the limit ring 45 to rotate. The rotation of the limit ring 45 can rotate the rolling cutter 5 threadedly connected to the positioning head 417 out. While rotating out, the jacking assembly on the second guide block 6 will cooperate with the jacking assembly to remove the old rolling cutter 5, and at the same time, the new rolling cutter 5 will be aligned with the limit ring 45, and the new rolling cutter 5 will be installed on the positioning head 417 through the limit ring 45. The cooperation of the jacking assembly and the jacking assembly can realize the rapid and accurate replacement of the rolling cutter 5, thereby ensuring the continuous operation of the production line and reducing the production interruption caused by the replacement of the cutter.

[0044] The problem of low efficiency in rolling hole processing is solved.

[0045] like Figure 3 and Figure 6As shown, the top disassembly assembly of this embodiment also includes a fixed shaft 43 fixedly connected to the output end of the second motor 42, the circumferential surface of the fixed shaft 43 is fixedly connected to two limit bars 44, the circumferential surface of the fixed shaft 43 is slidably connected to the first gear 413, the first gear 413 is meshed with the second gear 414, the outer surfaces of the first gear 413 and the second gear 414 are provided with the same limit ring 45, the limit ring 45 is provided with an annular groove 412, the lower surface of the limit ring 45 is provided with a preload, and the preload is used to provide a preload force to the rolling knife 5.

[0046] Specifically, when the limiting ring 45 is used to remove the rolling cutter 5, because the rolling cutter 5 is threadedly connected to the positioning head 417, the limiting ring 45 will gradually move away from the positioning head 417 during the removal process, so the limiting ring 45 will also move outward, so that the removal function can be stably achieved. By fixing the fixed shaft 43 to the output end of the second motor 42, two limiting strips 44 are fixed to the circumferential surface of the fixed shaft 43, so that the first gear 413 on the fixed shaft 43 can slide along the fixed shaft 43 while rotating, so that the first gear 413 on the fixed shaft 43 can slide along the fixed shaft 43. A gear 413 drives the second gear 414 to disassemble the rolling knife 5 more stably. The first gear 413 and the second gear 414 are rotatably set in the annular groove 412 inside the limiting ring 45, which limits the gears to prevent deformation. In addition, during disassembly, the rolling knife 5 is abutted by the preload member, imitating the thrust of a person on the bolt when disassembling the bolt. In this way, the rolling knife 5 can be disassembled more stably and the rolling knife 5 can be prevented from shifting during the disassembly process. In addition, the preload member is electrically controlled to achieve the clamping and release of the rolling knife 5.

[0047] like Figure 3 and Figure 6 As shown, in the present embodiment, the second gear 414 is initially sleeved on the rolling head on one side of the positioning head 417, and a slot 415 is provided in the middle of the second gear 414, which is engaged with the hexagonal circumferential surface of the rolling cutter 5. After the second motor 42 is started, it will drive the first gear 413 to rotate, thereby driving the second gear 414 to rotate, and then the rolling head threadedly connected in the positioning head 417 is rotated out, and then the old rolling cutter 5 is collected in cooperation with the lifting assembly on the second guide block 6, and then the new rolling cutter 5 needs to be replaced at the same time.

[0048] Specifically, when the second gear 414 rotates to remove the rolling knife 5, the preloaded part releases the rolling knife 5. At this time, the lifting assembly on the second guide block 6 just moves to the corresponding position. The lifting assembly will push the limit ring 45, and then the rolling knife 5 will fall onto the lifting assembly. At this time, the second guide block 6 will continue to approach the first guide block 4, and then the lifting assembly will continue to rise until the new rolling knife 5 is aligned with the limit ring 45, and then the limit ring 45 and the preloaded part clamp the new rolling knife 5, and then start the second motor 42, and rotate to drive the limit ring 45 to install the new rolling knife 5 on the positioning head 417.

[0049] like Figure 3 and Figure 6 As shown, the preload member of this embodiment includes a second guide rail 46 fixed to the lower surface of the positioning head 417, and a third guide block 47 is fixed to the lower surface of the limiting ring 45. The third guide block 47 can slide along the second guide rail 46, thereby limiting the sliding of the limiting ring 45.

[0050] Specifically, during the disassembly of the limit ring 45, it will be limited by the second guide rail 46 on the lower surface of the positioning head 417. Because the position of the limit ring 45 corresponding to the second guide rail 46 is fixedly connected to the third guide block 47, the third guide block 47 can slide along the second guide rail 46, thereby achieving the effect of assisting the disassembly of the limit ring 45.

[0051] like Figure 6 As shown, the preload member of this embodiment also includes a positioning frame 48 fixedly connected to the upper surface of the third guide block 47, a first groove body 49 is opened inside the positioning frame 48, a compression spring 410 is fixedly connected to the bottom wall of the first groove body 49, a protrusion 411 is fixedly connected to the top end of the compression spring 410, and the protrusion 411 can abut against one side of the rolling cutter 5 head.

[0052] Specifically, a positioning frame 48 is fixedly connected to the upper surface of the third guide block 47. When disassembly is required, the permanent magnet block on the bottom wall of the positioning frame 48 is energized and has magnetism, which will repel the compression spring 410, causing the compression spring 410 to push up the protrusion 411, and the protrusion 411 will abut against one side of the rolling knife 5, thereby preventing the rolling knife 5 from escaping from the limit ring 45 during rotation. After disassembly is completed, the permanent magnet block is powered off and loses its magnetism, and the protrusion 411 retracts into the first groove 49, releasing the rolling knife 5, achieving a stable disassembly effect. At the same time, the third guide block 47 will also assist the disassembly of the limit ring 45, preventing the limit ring 45 from rotating as a whole, further improving the stability of equipment disassembly.

[0053] like Figure 6As shown, in this embodiment, an electro-permanent magnet block is provided on the bottom wall of the positioning frame 48. When the rolling knife 5 is disassembled, the electrophoretic magnet block on the bottom wall of the positioning frame 48 is activated. After the electro-permanent magnet block is activated, it will repel the protrusion 411, and then make the protrusion 411 slide upward, and pull the compression spring 410, so that the protrusion 411 will abut against one side of the rolling knife 5, thereby fixing the rolling knife 5 more stably and disassembling it more effectively.

[0054] Specifically, an electro-permanent magnet block is installed at the bottom of the positioning frame 48. When the rolling cutter 5 needs to be removed, the electro-permanent magnet block is activated to generate a repulsive force on the protrusion 411. The protrusion 411 is repelled upward and slides out of the first groove 49. In this way, the protrusion 411 can be in close contact with one side of the rolling cutter 5, thereby achieving a more stable fixation of the rolling cutter 5.

[0055] Embodiment 2: Figures 1 to 6 As shown, compared with Example 1, another embodiment of the present invention is: the lifting assembly includes a rack plate 416 fixedly connected to one side of the first motor 41, the upper surface of the second guide block 6 is rotatably connected to a reciprocating screw 61, the top of the reciprocating screw 61 is fixedly connected to a rotating gear 62, the rotating gear 62 can engage with the rack plate 416, the circumferential surface of the reciprocating screw 61 is slidably connected to a sliding rod 63, the top of the sliding rod 63 is fixedly connected to a sliding frame 64, one side of the sliding frame 64 is fixedly connected to two cross plates 65, the upper surface of each cross plate 65 is fixedly connected to a bottom block 66, the bottom block 66 is used to place the rolling knife 5.

[0056] Specifically, the specific movement of the lifting assembly is that when the second guide block 6 moves toward the first guide block 4 and approaches the middle position, the rack plate 416 on one side of the first guide block 4 will mesh with the rotating gear 62 at the top of the reciprocating screw 61 of the second guide block 6, and then the rotating gear 62 will passively rotate, and the rotation of the rotating gear 62 will drive the reciprocating screw 61 to rotate, and then the reciprocating screw 61 will drive the sliding rod 63 to move slowly upward, and the sliding rod 63 will drive the sliding frame 64 to move slowly upward, approaching the disassembled rolling knife 5, and in the process of approaching the rolling knife 5, the preload is released, and then the limit ring 45 is separated from the rolling knife 5, and the rolling knife 5 will fall onto one of the horizontal plates 65 of the sliding frame 64, As the second guide block 6 continues to slide, the sliding frame 64 continues to rise upward, and then the new rolling knife 5 in the middle of the sliding frame 64 will be aligned with the slot 415 of the limiting ring 45. At this time, the sliding rod 63 just slides to the top, and the rotating gear 62 is also stuck. The second guide block 6 stops sliding, and at this time, it drives the limiting ring 45 to clamp the new rolling knife 5, and then the preload part is started to limit the rolling knife 5 on the limiting ring 45. At this time, the limiting ring 45 and the new rolling knife 5 are pushed to move until the rolling knife 5 is in contact with the threaded hole of the positioning head 417, and the second motor 42 is started to drive the second gear 414 to rotate. The rotation direction at this time is opposite to the direction during disassembly, thereby fixing the new rolling knife 5 to the positioning head 417.

[0057] like Figure 4 As shown, in this embodiment, two sliding plates 67 are fixedly connected to the upper surface of the second guide block 6, and the sliding plates 67 are used to limit the sliding frame 64 so that the sliding frame 64 can slide up and down stably. An auxiliary block 69 is fixedly connected to one end of the sliding rod 63, and an auxiliary plate 68 is fixedly connected to the upper surface of the second guide block 6. During the upward sliding process of the sliding rod 63, the auxiliary block 69 can slide along the auxiliary plate 68 to achieve a stable limiting effect.

[0058] Specifically, through the cooperation of the two sliding plates 67 and the sliding frame 64, effective limitation of the sliding frame 64 in the vertical direction is achieved. When the sliding frame 64 slides up and down, its two sides are tightly fitted by the sliding plates 67, thereby avoiding shaking or deviation and ensuring the stability and accuracy of sliding. At the same time, the auxiliary block 69 fixed on the sliding rod 63 interacts with the auxiliary plate 68 on the upper surface of the second guide block 6. When the sliding rod 63 slides upward, the auxiliary block 69 moves smoothly along the trajectory of the auxiliary plate 68, thereby improving the stability of the sliding rod 63 sliding up and down.

[0059] like Figure 4 As shown, in this embodiment, a first hydraulic cylinder 610 is fixedly connected to one side of the sliding plate 67 , and an electro-permanent magnetic disk 611 is fixedly connected to the output end of the first hydraulic cylinder 610 . The electro-permanent magnetic disk 611 can magnetically push the limit ring 45 .

[0060] Specifically, after the preload releases the old rolling blade 5, the first hydraulic cylinder 610 is started to drive the electric permanent magnet 611 at its output end close to the limit ring 45. When the limit ring 45 just breaks away from the old rolling blade 5, the old rolling blade 5 will fall onto the cross plate 65 of the sliding frame 64. The sliding frame 64 continues to move upward. When the new rolling blade 5 is aligned with the slot 415 of the limit ring 45, the first hydraulic cylinder 610 is started to drive the limit ring 45 to be clamped on the new rolling blade 5. At the same time, the new rolling blade 5 is clamped by the preload, and then the first hydraulic cylinder 610 drives the limit ring 45 and the new rolling blade 5 to be installed close to the positioning head 417.

[0061] Working principle: First, fix the part to be ground by the triangular chuck 2. After the triangular chuck 2 fixes the part, start several screws on one side of the machine body 1, as shown in the attached figure. Figure 1As shown in the figure, several screw rods will simultaneously drive the first guide rail 3 to approach the triangular chuck 2, which can drive the first guide block 4 on the first guide rail 3. The upper surface of the first guide block 4 is fixed with a rolling cutter 5. When the rolling cutter 5 is aligned with the part, the first motor 41 on the first guide block 4 is started to drive the positioning head 417 to rotate, so as to face the circular hole on the surface of the part, and then the first guide rail 3 is started again, and the first guide rail 3 will drive the rolling cutter 5 to insert into the hole inside the part, and then the diamond ball on one side of the rolling cutter 5 will contact the hole. The inner wall of the part is abutted, and then the built-in motor of the machine body 1 is started to drive the triangular chuck 2 to rotate, and then the rolling cutter 5 grinds the inner wall of the part hole by slowly feeding the cutter, thereby forming a mirror hole, and this operation is repeated continuously to grind the part. However, when the rolling cutter 5 has been used for a certain period of time, the cutter head needs to be replaced. At this time, the first motor 41 is rotated to drive the positioning head 417 and the rolling cutter 5 to reset to be parallel to the first guide rail 3, and then the second guide block 6 at the other end of the first guide rail 3 is started, and the first guide block 4 on the first guide block 4 is started at the same time. The second motor 42 drives the limiting ring 45 to rotate. Because the rolling knife 5 is threadedly connected to the positioning head 417, the limiting ring 45 will gradually move away from the positioning head 417 during the removal process of the rolling knife 5. Therefore, the limiting ring 45 will also move outward, so that the removal function can be stably realized. The fixed shaft 43 is fixedly connected to the output end of the second motor 42, and two limiting strips 44 are fixedly connected to the circumferential surface of the fixed shaft 43, so that the first gear 413 on the fixed shaft 43 can slide along the fixed shaft 43 while rotating. In this way, the first gear 413 can drive the second gear 414 to dismantle the rolling knife 5 more stably. The first gear 413 and the second gear 414 are rotatably arranged in the annular groove 412 inside the limiting ring 45, and the gears are limited to prevent deformation. In addition, during disassembly, the rolling knife 5 is abutted by the preload member, and the imitation person will have a thrust on the bolt when disassembling the bolt. In this way, the rolling knife 5 can be disassembled more stably to prevent the rolling knife 5 from deviating during the disassembly process.

[0062] In addition, during the disassembly of the limit ring 45, the second guide rail 46 on the lower surface of the positioning head 417 will be used for limiting. Because the position of the limit ring 45 corresponding to the second guide rail 46 is fixedly connected to the third guide block 47, the third guide block 47 can slide along the second guide rail 46, thereby achieving the effect of assisting the disassembly of the limit ring 45. At the same time, a positioning frame 48 is fixedly connected to the upper surface of the third guide block 47. The electric permanent magnet block on the bottom wall of the positioning frame 48 is energized and has magnetism, which will repel the compression spring 410, causing the compression spring 410 to push the protrusion 411 upward, and the protrusion 411 will abut against one side of the rolling knife 5, thereby preventing the rolling knife 5 from detaching from the limit ring 45 during the rotation process. After the disassembly is completed, the electric permanent magnet block is powered off and loses its magnetism, and the protrusion 411 retracts into the first groove 49, releasing the rolling knife 5, achieving the effect of stable disassembly. At the same time, the third guide block 47 will also assist the disassembly of the limit ring 45, preventing the limit ring 45 from rotating as a whole, further improving the stability of the equipment disassembly.

[0063] At the same time of rotating out, the lifting assembly on the second guide block 6 will cooperate with the lifting assembly to remove the old rolling knife 5, that is, when the second guide block 6 moves toward the first guide block 4 and approaches the middle position, the rack plate 416 on one side of the first guide block 4 will mesh with the rotating gear 62 at the top of the reciprocating screw 61 of the second guide block 6, and then the rotating gear 62 will rotate passively, and the rotation of the rotating gear 62 will drive the reciprocating screw 61 to rotate, and then the reciprocating screw 61 will drive the sliding rod 63 to move slowly upward, and the sliding rod 63 will drive the sliding frame 64 to move slowly upward, approaching the disassembled rolling knife 5, and in the process of approaching the rolling knife 5, the preload will be released, and then the limit ring 45 will be separated from the rolling knife 5, and the rolling knife 5 will fall onto one of the cross plates 65 of the sliding frame 64, and the second guide block 6 will continue to slide. Continue to rise upward, and then the new rolling knife 5 in the middle of the sliding frame 64 will be aligned with the slot 415 of the limiting ring 45. At this time, the sliding rod 63 just slides to the top, the rotating gear 62 is also stuck, and the second guide block 6 stops sliding, at this time driving the limiting ring 45 to clamp the new rolling knife 5, and then start the preload part to limit the rolling knife 5 on the limiting ring 45. At this time, the limiting ring 45 and the new rolling knife 5 are pushed to move until the rolling knife 5 is in contact with the threaded hole of the positioning head 417, and the second motor 42 is started to drive the second gear 414 to rotate. The rotation direction at this time is opposite to the direction during disassembly, so that the new rolling knife 5 is fixed to the positioning head 417. Through the cooperation of the top disassembly assembly and the jacking assembly, the rolling knife 5 can be replaced quickly and accurately, ensuring the continuous operation of the production line and reducing production interruptions caused by tool replacement.
