[0007] For example, in a tapping device and method for fastener processing provided by at least one embodiment of the present disclosure, the oil tank is communicated with the machine tool.

The circumferential surface of the first reciprocating lead screw is slidably connected to the clamping plate, improving the smoothness of the tapping work, reducing the wear of the tap, avoiding the high-temperature adhesion of the fastener and the tap, and further affecting the normal operation of the equipment. At the same time, it effectively reduces the surface roughness of the thread, reduces the tap wear, extends the tool life, ensures sufficient lubrication of the processing area, and reduces the waste of oil fluid and the adhesion of chips.

[0008] According to another aspect, at least one embodiment of the present disclosure further provides a tapping device and method for fastener processing.

An oil leakage slot is opened at the bottom of the machine tool where the filter plate is located. A leakage slot is opened on the surface of the processing table. An inclined surface is arranged on the surface of the clamping plate. One end of the pushing plate close to the processing table is of an inclined surface type, realizing automatic feeding, realizing continuous processing, reducing manual intervention, greatly improving the production efficiency, neatly stacking at the same time, reducing the collision damage caused by manual handling, and being suitable for batch production.

[0009] A collecting device for collecting the waste inside the waste slot is arranged on the surface of the clamping plate. The collecting device includes a rotating shaft sleeved on the surface of the clamping plate. A first roller is fixedly installed on the circumferential surface of the rotating shaft. A material pushing cylinder is fixedly installed on the circumferential surface of the rotating shaft. A sleeve plate is sleeved on the circumferential surface of the rotating shaft. A first rotating rod is rotatably installed at one end of the sleeve plate away from the material pushing cylinder. A second roller is fixedly installed on the circumferential surface of the first rotating rod. An arc plate is fixedly installed on the surface of the machine tool to collect waste materials, improve resource utilization rate, reduce environmental pollution, thereby keeping the workshop clean and reducing the impact of waste materials and oil stains on the working environment.

[0010] The first roller contacts the waste slot. A brush plate is arranged on the circumferential surface of the material pushing cylinder. The sleeve plate is L-shaped, realizing the recycling of lubricating oil, improving the environmental protection and economy of the equipment, making the operation more environmentally friendly, reducing the consumable cost at the same time, meeting the long-term and efficient production requirements, further improving the resource utilization rate and reducing environmental pollution.

[0011] The second roller contacts the arc plate. The arc plate is arc-shaped, avoiding pushing the waste into a dead corner when approaching the edge of the waste slot, increasing the cleaning difficulty for subsequent workers, improving the equipment maintenance efficiency, enabling the waste to be discharged smoothly, avoiding equipment jamming or failure caused by accumulation, and ensuring continuous production.

[0012] For example, in a tapping device and method for fastener processing provided by at least one embodiment of the present disclosure, an auxiliary device for cleaning the material pushing cylinder is arranged on the surface of the sleeve plate. The auxiliary device includes a second rotating rod rotatably penetrating through the surface of the sleeve plate. An eccentric wheel is fixedly installed on the circumferential surface of the second rotating rod. An L-shaped plate is slidably installed on the surface of the sleeve plate. A knocking rod is fixedly installed at the bottom of the L-shaped plate. A telescopic spring rod is fixedly installed at the bottom of the sleeve plate. A third reciprocating lead screw is rotatably installed on the surface of the filter plate. A third gear disc is fixedly installed at one end of the third reciprocating lead screw away from the filter plate. A scraping plate is slidably installed on the circumferential surface of the third reciprocating lead screw. A dial ring is fixedly installed at one end of the third reciprocating lead screw close to the filter plate, shaking off the waste chips adhering to or possibly jamming the rotating shaft, avoiding the normal operation of the material pushing cylinder being affected by waste chips, avoiding downtime caused by jamming, improving production efficiency, and reducing the accumulation of lubricating oil and sundries.

[0013] The second rotating rod is fixedly connected to one end of the first rotating rod away from the second roller. The L-shaped plate is shaped like an L. The free end of the telescopic spring rod is fixedly connected to the L-shaped plate. The third reciprocating screw rod is threadedly connected to the scraper. The third gear disc meshes with the first gear disc. The scraper is slidably connected to the inner wall of the machine tool. The dial ring contacts the surface of the first gear disc. The angle of the dial ring is set as an inclination angle to prevent lubricating oil from sticking to the inner wall, avoid the accumulation and adhesion of lubricating oil, which helps prevent the formation of dirt by lubricating oil, thereby reducing the impact and damage to machine components, keeping the machine tool clean and running smoothly, and ensuring that the lubricating oil circulation system always maintains efficient operation.

[0014] A tapping method for fastener processing, using the above-mentioned tapping device for fastener processing, includes: Step 1: The worker places the fastener inside the stacking cylinder, starts the second hydraulic cylinder, and the output end of the second hydraulic cylinder moves towards the processing table, driving the pushing plate to move. At the same time, the pushing plate moves to contact and push the fastener towards the processing table until it reaches the tapping area. At the same time, since the pushing plate is threadedly connected to the second reciprocating screw rod, the movement of the pushing plate drives the second reciprocating screw rod to rotate, and the rotation of the second reciprocating screw rod drives the first gear disc to rotate; Step 2: Since the first gear disc is threadedly connected to the second gear disc, the rotation of the first gear disc drives the second gear disc to rotate at this time. The rotation of the second gear disc drives the first reciprocating screw rod to rotate. At the same time, since the first reciprocating screw rod is threadedly connected to the clamping plate, the rotation of the first reciprocating screw rod drives the clamping plate to move towards the pushing plate, and the clamping plate moves to clamp the fastener directly. At this time, the clamping plates at both ends and the pushing plate fix and clamp it simultaneously; Step 3: After the fastener is clamped, start the first hydraulic cylinder, and the output end of the first hydraulic cylinder moves downward to drive the tapping frame to move downward. At this time, the tapping frame moves downward until it contacts the fastener to tap it, and at the same time, the fuel tank sprays lubricating oil onto the surface of the fastener; Step 4: Subsequently, after the fastener is tapped, the pushing plate moves away from the processing table under the action of the second hydraulic cylinder. At the same time, the movement of the pushing plate drives the clamping plate to move back to its original position. When the pushing plate moves inside the stacking cylinder and continues to move, the fasteners stacked inside the stacking cylinder lose the support of the pushing plate for them; Step 5: At this time, the fastener falls under the action of gravity. At this time, the second hydraulic cylinder pushes the pushing plate to move, pushing the fastener towards the processing table. Subsequently, the pushing plate moves to re-limit the fasteners stacked in the stacking cylinder, realizing automatic feeding. When the processed fastener is pushed by the next fastener pushed by the pushing plate until it slides into the finished product cylinder through the chute.

[0015] The beneficial effects of the embodiments of the present disclosure are: In the present disclosure, the reciprocating screw rod 1 rotates to drive the clamping plate to move towards the direction close to the pushing plate. The clamping plate moves to clamp the fastener directly. At this time, the clamping plates at both ends and the pushing plate fix and clamp it simultaneously, achieving the clamping effect on the fastener, improving the stability and accuracy of the fastener during tapping, avoiding the influence of the shaking or vibration of the fastener on the processing accuracy during tapping, and even damaging the tapping frame, thereby improving the safety during the equipment processing work, and further ensuring the normal operation of the equipment and the operation safety of the staff.

[0016] In the present disclosure, the tapping frame moves downward until it contacts the fastener to tap it. At the same time, the oil tank sprays lubricating oil onto the surface of the fastener, improving the smoothness of the tapping work, reducing the wear of the tap, avoiding the high-temperature adhesion between the fastener and the tap, and further affecting the normal operation of the equipment. At the same time, it effectively reduces the surface roughness of the thread, reduces the tap wear, extends the tool life, ensures sufficient lubrication of the processing area, reduces oil waste and chip adhesion at the same time. The pushing plate moves to re-limit the fasteners stacked in the stacking cylinder, realizing automatic feeding, continuous processing, reducing manual intervention, greatly improving the production efficiency, neatly stacking at the same time, reducing the bump damage caused by manual handling, suitable for batch production. When the processed fasteners are pushed by the fasteners in the next pushing plate towards the finished product cylinder until they slide into the inside of the finished product cylinder through the chute, the stacking of the product fasteners is realized at this time.

[0017] In the present disclosure, the rotation of the rotating shaft drives the material dialing cylinder to rotate, the rotation of the material dialing cylinder drives the brush plate to rotate, and the rotation of the brush plate dials and pushes the accumulated or splashed lubricating oil and waste chips to the filter plate to collect the waste, improving the resource utilization rate, reducing environmental pollution, thereby keeping the workshop clean, reducing the influence of waste and oil pollution on the working environment. Because the roller 2 contacts the arc plate, at this time, the roller 2 will gradually rise when it moves under the action of the arc plate, and then descend after passing through the highest point, avoiding pushing the waste into a dead end when approaching the edge of the waste chute, increasing the cleaning difficulty for the subsequent staff, improving the equipment maintenance efficiency, enabling the waste to be discharged smoothly, avoiding equipment jamming or failure caused by accumulation, and ensuring continuous production.

[0018] In the present disclosure, the lubricating oil filters down through its filter holes and then flows into the inside of the machine tool, is filtered and then pumped back into the inside of the oil tank to realize the recycling of the lubricating oil, improving the environmental protection and economy of the equipment, making the operation more environmentally friendly, reducing the consumable cost at the same time, meeting the long-term high-efficiency production requirements, further improving the resource utilization rate, and reducing environmental pollution.

[0019] In the present disclosure, the template vibrates under the action of the knocking rod. At this time, the template transmits the vibration to the material feeding cylinder, shakes off the waste chips adhering to or possibly jamming the rotating shaft, avoids affecting the normal operation of the material feeding cylinder due to waste chips, avoids downtime caused by jamming, improves production efficiency, and further reduces the accumulation of lubricating oil and sundries. The reciprocating lead screw three rotates to drive the scraper to move. At this time, the movement of the scraper scrapes off the residual and adhering lubricating oil on the inner wall of the machine tool, and then filters it through the filter plate, avoiding the adhesion of the lubricating oil on the inner wall, avoiding the accumulation and adhesion of the lubricating oil, which helps to prevent the formation of dirt by the lubricating oil, and further reduces the impact and damage to the machine components, keeps the machine tool clean and running smoothly, and ensures that the lubricating oil circulation system always maintains efficient operation.

[0027] Such as Figures 1 to 7As shown, it shows a tapping device and method for fastener processing in an embodiment of the present disclosure, including a machine tool 1. A first hydraulic cylinder 21 is fixedly installed on the surface of the machine tool 1, and a second hydraulic cylinder 22 is fixedly installed on the surface of the machine tool 1. A tapping frame 3 is slidably installed on the inner wall of the machine tool 1. An oil tank 4 is fixedly installed on the top of the tapping frame 3. A circulating device for realizing the processing cycle of fasteners is arranged on the surface of the machine tool 1. The circulating device includes a stacking cylinder 51, and the stacking cylinder 51 is fixedly installed on the surface of the machine tool 1. A processing table 52 is fixedly installed on the surface of the machine tool 1. A pushing plate 53 is slidably installed on the surface of the machine tool 1. A finished product cylinder 54 is fixedly installed on the surface of the machine tool 1. A first reciprocating lead screw 55 is rotatably penetrated through the surface of the machine tool 1. A waste slot is opened on the surface of the machine tool 1. A clamping plate 56 is slidably installed on the inner wall of the waste slot. A second reciprocating lead screw 57 is rotatably penetrated through the surface of the machine tool 1. A first gear disk 58 is fixedly installed at one end of the second reciprocating lead screw 57 close to the processing table 52. A filter plate 59 is fixedly installed on the inner wall of the machine tool 1. A stacking slot 510 is opened on the inner wall of the machine tool 1. A second gear disk 511 is fixedly installed at one end of the first reciprocating lead screw 55 close to the second reciprocating lead screw 57. Since the first gear disk 58 and the second gear disk 511 are threadedly connected, at this time, the rotation of the first gear disk 58 drives the rotation of the second gear disk 511, and the rotation of the second gear disk 511 drives the rotation of the first reciprocating lead screw 55.

[0028] The oil tank 4 is communicated with the machine tool 1. The pushing plate 53 is fixedly connected to the output end of the second hydraulic cylinder 22. The surface of the finished product cylinder 54 is provided with an inclined surface. A first chute is opened on the surface of the machine tool 1. The pushing plate 53 is slidably connected with the stacking cylinder 51. The pushing plate 53 is threadedly connected with the second reciprocating lead screw 57. The first gear disk 58 meshes with the second gear disk 511. The circumferential surface of the first reciprocating lead screw 55 is slidably connected with the clamping plate 56. The rotation of the first reciprocating lead screw 55 drives the clamping plate 56 to move in the direction close to the pushing plate 53, and the movement of the clamping plate 56 directly clamps the fastener.

[0029] In some examples, the clamping plate 56 is threadedly connected with the first reciprocating lead screw 55. The surface of the second gear disk 511 is provided with an inclined surface. An oil leakage slot is opened at the bottom of the machine tool 1 where the filter plate 59 is located. A leakage slot is opened on the surface of the processing table 52. The surface of the clamping plate 56 is provided with an inclined surface. One end of the pushing plate 53 close to the processing table 52 is provided with an inclined surface four. The movement of the pushing plate 53 contacts and pushes the fastener to move in the direction close to the processing table 52 until it reaches the tapping area.

[0030] For example, as Figures 1 to 7As shown, the worker places the fastener inside the stacking cylinder 51 and activates the second hydraulic cylinder 22. The output end of the second hydraulic cylinder 22 moves towards the processing table 52, driving the pushing plate 53 to move. At the same time, the pushing plate 53 moves to contact and push the fastener towards the processing table 52 until it reaches the tapping area. Meanwhile, since the pushing plate 53 is threadedly connected to the second reciprocating lead screw 57, the movement of the pushing plate 53 drives the second reciprocating lead screw 57 to rotate. At the same time, the rotation of the second reciprocating lead screw 57 drives the first gear disk 58 to rotate. Since the first gear disk 58 is threadedly connected to the second gear disk 511, at this time, the rotation of the first gear disk 58 drives the second gear disk 511 to rotate. The rotation of the second gear disk 511 drives the first reciprocating lead screw 55 to rotate. At the same time, since the first reciprocating lead screw 55 is threadedly connected to the clamping plate 56, the rotation of the first reciprocating lead screw 55 drives the clamping plate 56 to move towards the pushing plate 53. The clamping plate 56 moves to clamp the fastener. At this time, the clamping plates 56 at both ends and the pushing plate 53 simultaneously fix and clamp it, achieving the clamping effect of the fastener, improving the stability and accuracy of the fastener during tapping, avoiding the influence of the shaking or vibration of the fastener on the processing accuracy during tapping, and even damaging the tapping frame 3, thereby improving the safety during the equipment processing work, and then ensuring the normal operation of the equipment and the operation safety of the worker. When the fastener is clamped, the first hydraulic cylinder 21 is activated. The output end of the first hydraulic cylinder 21 moves downward, driving the tapping frame 3 to move downward. At this time, the tapping frame 3 moves downward until it contacts the fastener to tap it. At the same time, the oil tank 4 sprays lubricating oil onto the surface of the fastener, improving the smoothness of the tapping work, reducing the wear of the tap, avoiding the high-temperature adhesion of the fastener and the tap, thereby affecting the normal operation of the equipment. At the same time, it effectively reduces the surface roughness of the thread, reduces the tap wear, extends the tool life, ensures sufficient lubrication in the processing area, and at the same time reduces the waste of oil and the adhesion of chips. Subsequently, after the fastener is tapped, the pushing plate 53 moves away from the processing table 52 under the action of the second hydraulic cylinder 22. At the same time, the movement of the pushing plate 53 drives the clamping plate 56 to move back to its original position. When the pushing plate 53 moves inside the stacking cylinder 51 and continues to move, at this time, the fasteners stacked inside the stacking cylinder 51 lose the support of the pushing plate 53. At this time, the fasteners fall under the action of gravity. At this time, the second hydraulic cylinder 22 pushes the pushing plate 53 to move, pushing the fastener towards the processing table 52. Subsequently, the pushing plate 53 moves to re-limit the fasteners stacked inside the stacking cylinder 51, realizing automatic feeding, realizing continuous processing, reducing manual intervention, greatly improving the production efficiency, and at the same time neatly stacking, reducing the collision damage caused by manual handling, being suitable for batch production. When the processed fastener is pushed by the next fastener pushed by the pushing plate 53 until it slides into the finished product cylinder 54 through the chute, at this time, the stacking of the product fasteners is realized.

[0031] As Figures 1 to 7As shown, it shows that in another embodiment of the present disclosure, a collection device for collecting waste inside the waste chute is provided on the surface of the clamping plate 56. The collection device includes a rotating shaft 61 sleeved on the surface of the clamping plate 56. A first roller 62 is fixedly installed on the circumferential surface of the rotating shaft 61, a material pushing cylinder 63 is fixedly installed on the circumferential surface of the rotating shaft 61, a sleeve plate 64 is sleeved on the circumferential surface of the rotating shaft 61, a first rotating rod 65 is rotatably installed at one end of the sleeve plate 64 away from the material pushing cylinder 63, and a second roller 66 is fixedly installed on the circumferential surface of the first rotating rod 65. An arc plate 67 is fixedly installed on the surface of the machine tool 1. Since the second roller 66 contacts the arc plate 67, at this time, the second roller 66 will gradually rise when moving under the action of the arc plate 67, and then descend after passing through the highest point.

[0032] The first roller 62 contacts the waste chute. A brush plate is provided on the circumferential surface of the material pushing cylinder 63. The rotation of the rotating shaft 61 drives the rotation of the material pushing cylinder 63, and the rotation of the material pushing cylinder 63 drives the rotation of the brush plate. The sleeve plate 64 is L-shaped.

[0033] The second roller 66 contacts the arc plate 67. The arc plate 67 is arc-shaped. When the clamping plate 56 moves towards the arc plate 67, it drives the second roller 66 to move. Since the second roller 66 contacts the arc plate 67.

[0034] An auxiliary device for cleaning the material pushing cylinder 63 is provided on the surface of the sleeve plate 64. The auxiliary device includes a second rotating rod 71 rotatably penetrating the surface of the sleeve plate 64. An eccentric wheel 72 is fixedly installed on the circumferential surface of the second rotating rod 71. An L-shaped plate 73 is slidably installed on the surface of the sleeve plate 64. A knocking rod 74 is fixedly installed at the bottom of the L-shaped plate 73. A telescopic spring rod 75 is fixedly installed at the bottom of the sleeve plate 64. A third reciprocating screw rod 76 is rotatably installed on the surface of the filter plate 59. A third gear disk 77 is fixedly installed at one end of the third reciprocating screw rod 76 away from the filter plate 59. A scraping plate 78 is slidably installed on the circumferential surface of the third reciprocating screw rod 76. A dial ring 79 is fixedly installed at one end of the third reciprocating screw rod 76 close to the filter plate 59. The rotation of the third reciprocating screw rod 76 drives the rotation of the dial ring 79. At this time, the rotation of the dial ring 79 pushes the waste piled on the top of the filter plate 59 towards the stacking chute 510. In some examples, the second rotating rod 71 is fixedly connected to one end of the first rotating rod 65 away from the second roller 66. The L-shaped plate 73 is L-shaped. The free end of the telescopic spring rod 75 is fixedly connected to the L-shaped plate 73. The third reciprocating screw rod 76 is threadedly connected to the scraping plate 78. The third gear disk 77 meshes with the first gear disk 58. The scraping plate 78 is slidably connected to the inner wall of the machine tool 1. The dial ring 79 contacts the surface of the first gear disk 58. The angle of the dial ring 79 is set as an inclined angle. The rotation of the dial ring 79 pushes the waste piled on the top of the filter plate 59 towards the stacking chute 510, and then the waste slides down through the stacking chute 510.

[0035] For example, as Figures 1 to 7As shown, when the reciprocating lead screw 55 rotates under the action of the reciprocating lead screw 57, since the reciprocating lead screw 55 is threadedly connected to the clamping plate 56, the rotation of the reciprocating lead screw 55 drives the clamping plate 56 to move. At the same time, the movement of the clamping plate 56 drives the rotating shaft 61 to move, and the movement of the rotating shaft 61 drives the roller 62 to move. Since the roller 62 contacts the waste material groove, the movement of the roller 62 causes it to rotate under the action of the waste material groove. At the same time, the rotation of the roller 62 drives the rotating shaft 61 to rotate. At this time, the rotation of the rotating shaft 61 drives the material pushing cylinder 63 to rotate, and the rotation of the material pushing cylinder 63 drives the brush plate to rotate. The rotation of the brush plate deflects and pushes the accumulated or splashed lubricating oil and waste chips and advances them to the filter plate 59, collecting the waste materials, improving the resource utilization rate, reducing environmental pollution, thereby keeping the workshop clean, reducing the impact of waste materials and oil stains on the working environment. The waste materials containing lubricating oil fall on the top of the filter plate 59, and the lubricating oil filters through its filter holes and then flows into the interior of the machine tool 1, where it is filtered and then pumped back into the interior of the fuel tank 4 to achieve the recycling of the lubricating oil, improving the environmental protection and economy of the equipment, making the operation more environmentally friendly, reducing the consumable cost at the same time, meeting the requirements of long-term and efficient production, further improving the resource utilization rate, and reducing environmental pollution. When the clamping plate 56 moves towards the arc plate 67, it drives the roller 66 to move. Since the roller 66 contacts the arc plate 67, at this time, the movement of the roller 66 under the action of the arc plate 67 will gradually rise, and then fall after passing through the highest point, avoiding pushing the waste materials into dead corners when approaching the edge of the waste material groove, increasing the cleaning difficulty for subsequent workers, improving the equipment maintenance efficiency, enabling the smooth discharge of waste materials, avoiding equipment jamming or failures caused by accumulation, and ensuring continuous production. At this time, the roller 66 descends at the outermost edge, and then the clamping plate 56 moves towards the processing table 52 to clean and collect all the waste materials inside the waste material groove.

[0036] When the rotating rod 65 rotates under the action of the second roller 66, it drives the rotating rod 71 to rotate. At the same time, the rotating rod 71 rotates to drive the eccentric wheel 72 to rotate. The rotating eccentric wheel 72 contacts and presses the L-shaped plate 73 to move downward. At the same time, the downward movement of the L-shaped plate 73 drives the knocking rod 74 to move. The knocking rod 74 moves downward under the action of the L-shaped plate 73 to contact and collide with the surface of the sleeve plate 64. The sleeve plate 64 vibrates under the action of the knocking rod 74. At this time, the sleeve plate 64 transmits the vibration to the material feeding cylinder 63, vibrating off the waste chips adhering to or possibly jamming the rotating shaft 61, avoiding the influence of waste chips on the normal operation of the material feeding cylinder 63, avoiding downtime caused by jamming, improving production efficiency, and further reducing the accumulation of lubricating oil and sundries. When the second reciprocating lead screw 57 rotates, it drives the first gear disk 58 to rotate. Since the first gear disk 58 meshes with the third gear disk 77, the rotation of the first gear disk 58 drives the third gear disk 77 to rotate. At the same time, the rotation of the third gear disk 77 drives the third reciprocating lead screw 76 to rotate. The rotation of the third reciprocating lead screw 76 drives the dial ring 79 to rotate. At this time, the rotation of the dial ring 79 dials the waste material piled on the top of the filter plate 59 towards the material stacking groove 510. Subsequently, the waste material slides down through the material stacking groove 510. At the same time, since the third reciprocating lead screw 76 is threadedly connected to the scraper 78, the rotation of the third reciprocating lead screw 76 drives the scraper 78 to move. At this time, the movement of the scraper 78 scrapes off the residual lubricating oil adhering to the inner wall of the machine tool 1 and then filters it through the filter plate 59, avoiding the adhesion of lubricating oil to the inner wall, avoiding the accumulation and adhesion of lubricating oil, which helps prevent the formation of dirt by lubricating oil, and further reducing the influence and damage on machine components, keeping the machine tool 1 clean and running smoothly, and ensuring that the lubricating oil circulation system always maintains efficient operation.

[0037] A tapping method for fastener processing, comprising: Step 1: The staff places the fastener inside the material stacking cylinder 51, starts the second hydraulic cylinder 22, and the output end of the second hydraulic cylinder 22 moves towards the processing table 52, driving the pushing plate 53 to move. At the same time, the pushing plate 53 moves to contact and push the fastener towards the processing table 52 until it reaches the tapping area. At the same time, since the pushing plate 53 is threadedly connected to the second reciprocating lead screw 57, the movement of the pushing plate 53 drives the second reciprocating lead screw 57 to rotate. At the same time, the rotation of the second reciprocating lead screw 57 drives the first gear disk 58 to rotate; Step 2: Since the first gear disk 58 is threadedly connected to the second gear disk 511, at this time, the rotation of the first gear disk 58 drives the second gear disk 511 to rotate. The rotation of the second gear disk 511 drives the first reciprocating lead screw 55 to rotate. At the same time, since the first reciprocating lead screw 55 is threadedly connected to the clamping plate 56, the rotation of the first reciprocating lead screw 55 drives the clamping plate 56 to move towards the pushing plate 53. The movement of the clamping plate 56 clamps the fastener. At this time, the clamping plates 56 at both ends and the pushing plate 53 fix and clamp it simultaneously; Step 3: After the fastener is clamped, start hydraulic cylinder 1 (21). The output end of hydraulic cylinder 1 (21) moves downward to drive the tapping frame 3 downward. At this time, the tapping frame 3 moves downward until it contacts the fastener to tap it. Meanwhile, the oil tank 4 sprays lubricating oil onto the surface of the fastener; Step 4: Subsequently, after the tapping of the fastener is completed, the pusher plate 53 moves away from the processing table 52 under the action of hydraulic cylinder 2 (22). Meanwhile, the movement of the pusher plate 53 drives the clamping plate 56 to move back to its original position. When the pusher plate 53 moves into the inside of the stacking cylinder 51 and continues to move, the fasteners stacked inside the stacking cylinder 51 lose the support of the pusher plate 53; Step 5: At this time, the fasteners fall under the action of gravity. At this time, hydraulic cylinder 2 (22) pushes the pusher plate 53 to move and push the fasteners towards the direction close to the processing table 52. Subsequently, the pusher plate 53 moves to re-limit the fasteners stacked in the stacking cylinder 51, realizing automatic feeding. When the processed fasteners are pushed by the next fastener pushed by the pusher plate 53 until they slide into the inside of the finished product cylinder 54 through the chute.
