Description

Technical Field

[0001] This invention relates to the field of fastener cutting and hole-opening technology, and more particularly to a head cutting and hole-opening device for fastener production. Background Technology

[0002] In the fastener manufacturing industry, especially in the production of fasteners with head structures such as bolts and screws, head cutting and hole opening is one of the key process steps. The hole opening in the bolt head can meet the needs of subsequent assembly, functional expansion or marking.

[0003] Chinese Patent CN114769658B discloses a bolt head drilling device and method for bolt production. A first hydraulic jack is installed above a support frame and is fixedly connected to the support frame by bolts. A lifting device is installed at the lifting end of the first hydraulic jack and is fixedly connected to the first hydraulic jack by fastening screws. A toothed slide rod is provided on one side of the lifting device and is slidably connected to the lifting device. A first rotating box is installed on one side of the toothed slide rod and is fixedly connected to the toothed slide rod by fastening screws. A first drill bit is installed on one side of the first rotating box. Although the above patent can drill holes in bolt heads, which are fasteners, when the operator places the bolt in a fixed position, due to human error, the drilling position of the bolt is not perpendicular to the drill bit, resulting in a deviation between the drilling position and the drill bit, affecting the accuracy of the drilling.

[0004] The present invention aims to solve the problems existing in the above-mentioned patents. To this end, a head cutting hole-opening device for fastener production is proposed, which can correct and position the bolt head so that the bolt hole position is perpendicular to the drill bit, thereby improving the hole-opening accuracy. Summary of the Invention

[0005] To overcome the drawback that when operators place bolts in a fixed position, the bolt hole position is not perpendicular to the drill bit due to human error, resulting in deviation between the bolt hole position and the drill bit and affecting the accuracy of the hole opening, this invention provides a head cutting hole opening device for fastener production that can correct and position the bolt head so that the bolt hole position is perpendicular to the drill bit, thereby improving the accuracy of the hole opening.

[0006] This invention is achieved through the following technical solution:

[0007] A head-cutting and hole-opening device for fastener production includes a worktable and an N-shaped base fixed to the worktable. A placement ring is embedded and fixedly mounted on the N-shaped base. An electric drill bit is mounted on the N-shaped base. A chamfering machine, inclined in orientation, is mounted on the outer side of the N-shaped base. Both the chamfering machine and the electric drill bit are equipped with nozzles. A collection frame is placed inside the worktable. The device is characterized by further including a U-shaped plate fixed to the N-shaped base. An L-shaped grid plate is slidably connected to the inner side of the U-shaped plate. A frame is fixed to the L-shaped grid plate. Positioning plates are symmetrically slidably connected to the inner side of the frame. The positioning plates have openings for the electric drill bit to pass through. Through the through hole, drive screws that are threadedly connected to the positioning plate are rotatably connected to both sides of the frame. The threads of the drive screws on the left and right sides are opposite. A dual-axis motor is installed on the frame. The output shaft end of the dual-axis motor is fixedly connected to the end of the drive screw. The dual-axis motor is used to drive the drive screw to rotate. The drive screw drives the positioning plate to move inward and contact the bolt head, so that the positioning plate corrects and positions the bolt head perpendicular to the electric drill bit. A drive assembly is provided on the U-shaped plate to drive the L-shaped grid plate to move upward. A clamping assembly is provided on the n-shaped seat to clamp and fix the bolt.

[0008] Further explanation: the drive assembly includes a drive screw that rotates through the U-shaped plate, the drive screw being threadedly connected to the L-shaped grid plate for moving the L-shaped grid plate, and a drive motor mounted on the U-shaped plate, the output shaft end of the drive motor being fixedly connected to the end of the drive screw.

[0009] Further explanation: The clamping assembly includes an embedded annular plate fixed to the n-type seat, the annular plate corresponding to the placement ring, a rotating ring rotatably connected to the annular plate along the circumference, guide rods slidingly inserted at even intervals along the circumference on the rotating ring, and an arc-shaped clamping block fixed to the end of the guide rod to clamp and fix the bolt. A magnetic ring is fixed to the outer side of the annular plate along the circumference, and the inner side of the magnetic ring is in magnetic contact with the outer side of the rotating ring. A triggering assembly is provided between the n-type seat and the annular plate to drive the arc-shaped clamping block to move.

[0010] Further explanation: The triggering component includes an annular guide plate rotatably connected to the inner circumferential side of the annular plate. The annular guide plate has evenly spaced slotted holes along its circumferential direction. The slotted holes are slidably connected to the end of the arc-shaped clamping block to drive the arc-shaped clamping block to move. A worm gear is fixedly mounted on the annular guide plate along its circumferential direction. A worm gear that meshes with the worm gear is rotatably connected to the annular plate laterally. A stepper motor is mounted on the n-type seat. The end of the output shaft of the stepper motor is fixedly connected to the end of the worm gear.

[0011] Further explanation: The head cutting and hole-opening device for fastener production also includes a limiting component. The limiting component includes a fixed frame fixed to the inner side of the L-shaped grid plate. A guide rod is fixed to the fixed frame. A correction plate located between the left and right positioning plates is symmetrically slidably mounted on the guide rod for limiting the front and rear sides of the bolt head. A bidirectional lead screw is rotatably connected to the fixed frame. The threads on the front and rear sides of the bidirectional lead screw are opposite. The bidirectional lead screw is threadedly connected to the correction plate. A servo motor is installed on the fixed frame. The output shaft end of the servo motor is fixedly connected to the end of the bidirectional lead screw.

[0012] Further explanation: The head cutting and drilling device for fastener production also includes a detection component. The detection component includes a rodless cylinder fixed to an n-type base. The rodless cylinder is inclined. An opening plate is fixed to the moving part of the rodless cylinder for placing the detection rod. A clamping component is provided on the opening plate for clamping and fixing the detection rod. A guide plate is fixed to the rodless cylinder for guiding the detection rod. A receiving frame located below the guide plate is fixed to the n-type base for collecting the cut detection rod. An electric push rod is fixedly connected to the rodless cylinder. A cutter located below the guide plate is fixed to the end of the telescopic rod of the electric push rod for cutting the detection rod.

[0013] Further explanation: The clamping assembly includes an annular mounting plate fixed to the perforated plate, a movable rod symmetrically and slidingly passing through the annular mounting plate, a clamping frame fixed to the end of the movable rod for clamping and fixing the detection rod, and a connecting spring connecting the clamping frame and the annular mounting plate.

[0014] To further explain, the head cutting and drilling device for fastener production also includes a U-shaped strip fixed to the inside of the collection frame, and a filter frame placed inside the collection frame that contacts the top of the U-shaped strip for filtering debris from the cutting fluid.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. First, place the bolt into the placement ring. Then, start the drive motor to drive the drive screw to rotate forward, causing the L-shaped grid plate to move upward through the frame to the left and right sides of the bolt. Next, start the dual-axis motor to drive the drive screw to rotate forward. The drive screw moves the left and right positioning plates to contact the bolt head, thus correcting and positioning the bolt head. This ensures that the position where the bolt head needs to be drilled is perpendicular to the electric drill bit. Then, start the electric drill bit to cut and drill the bolt head after correction and positioning to prevent deviations in the bolt head position from affecting the drilling, thereby improving the accuracy of the drilling.

[0017] 2. Under the action of the straightening plate, whenever the positioning plate corrects and positions the bolt head on the left and right sides, the straightening plate can correct and position the bolt head on the front and rear sides, so that the longitudinal position of the bolt head is in a precise position. In this way, the longitudinal position of the bolt head can be prevented from affecting the accuracy of the hole opening, thereby further improving the accuracy of the bolt head cutting hole opening.

[0018] 3. Under the action of the detection rod, whenever the hole in the bolt head is chamfered and corresponds to the detection rod, the detection rod can move into the hole in the bolt head for detection. Then the detection rod moves back to its original position and is cut by the cutter. By checking the appearance of the detection rod, you can know whether the quality of the hole in the bolt head is qualified. In this way, it can prevent the unqualified hole in the bolt head from affecting subsequent use, thereby ensuring the quality of the bolt head hole. Attached Figure Description

The location descriptions selected in the specification, such as upper, lower, and lateral, also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0033] Example: A head-cutting and hole-opening device for fastener production; please refer to [link / reference]. Figures 1-6As shown, it includes a workbench 1 and an n-shaped base 2 fixed to the top of the workbench 1. An opening for debris and cutting fluid to pass through is located on the front top of the workbench 1. A placement ring 7 is embedded and fixed to the upper front side of the n-shaped base 2, allowing for bolt placement. An electric drill bit 3 is mounted on the upper left side of the front side of the n-shaped base 2. A chamfering machine 4 is mounted on the outer top left side of the n-shaped base 2. The chamfering machine 4 is angled. Both the chamfering machine 4 and the electric drill bit 3 are equipped with nozzles 5. A collection frame 6 is placed on the front side of the bottom of the workbench 1. The collection frame 6 is located directly below the opening of the workbench 1. The collection frame 6 can collect cutting fluid and debris. It also includes a U-shaped plate 8, an L-shaped grid plate 9, a frame 10, a positioning plate 11, a dual-axis motor 12, a drive screw 13, a drive assembly, and a clamping assembly. A U-shaped plate 8 is fixedly connected to the middle of the top of the n-shaped base 2. An L-shaped grid plate 9 is vertically slidably connected to the inside of the U-shaped plate 8. The frame 1 is fixedly connected to the top of the L-shaped grid plate 9. 0. A positioning plate 11 is symmetrically slidably connected to the inner side of the frame 10. The positioning plate 11 has a through hole through which the electric drill bit 3 passes. A drive screw 13 is rotatably connected to both sides of the frame 10. The threads of the drive screws 13 on the left and right sides are opposite. The drive screws 13 on the left and right sides are threadedly connected to the positioning plates 11 on the left and right sides respectively. A dual-axis motor 12 is installed in the middle of the inner side of the frame 10. The output shaft ends on the left and right sides of the dual-axis motor 12 are fixedly connected to the ends of the drive screws 13 on the left and right sides respectively. The dual-axis motor 12 is used to drive the drive screws 13 to rotate. The drive screws 13 drive the positioning plate 11 to move inward and contact the bolt head, so that the positioning plate 11 corrects and positions the bolt head perpendicular to the electric drill bit 3. A drive assembly is provided on the U-shaped plate 8. The drive assembly is used to drive the L-shaped grid plate 9 to move upward. A clamping assembly is provided on the n-shaped seat 2. When the clamping assembly is in operation, the clamping assembly can clamp and fix the bolt.

[0034] Please see Figure 3 As shown, the drive assembly includes a drive motor 14 and a drive screw 141. The drive screw 141 is rotatably connected to the bottom center of the U-shaped plate 8. The drive screw 141 is threaded to the rear side of the L-shaped grid plate 9. When the drive screw 141 rotates, it can drive the L-shaped grid plate 9 to move up and down. The drive motor 14 is installed on the outer bottom of the U-shaped plate 8. The output shaft end of the drive motor 14 is fixedly connected to the bottom end of the drive screw 141.

[0035] Please see Figures 4-6As shown, the clamping assembly includes an annular plate 15, a rotating ring 151, guide rods 152, arc-shaped clamps 153, a magnetic ring 154, and a triggering assembly. An annular plate 15 is embedded and fixedly connected to the upper center of the n-shaped base 2. The annular plate 15 corresponds directly to the placement ring 7. The rotating ring 151 is circumferentially connected to the front side of the annular plate 15. Four guide rods 152 are slidably connected to the rotating ring 151 at even intervals along the circumference. Arc-shaped clamps 153 are fixedly connected to the ends of the four guide rods 152 that are close to each other. When the arc-shaped clamps 153 move inward and contact the bolt, they clamp and fix the bolt. A magnetic ring 154 is circumferentially fixed to the front side of the outer side of the annular plate 15. The inner side of the magnetic ring 154 is in magnetic contact with the outer side of the rotating ring 151. A triggering assembly is provided between the n-shaped base 2 and the annular plate 15. When the triggering assembly operates, it triggers… The component can drive the arc-shaped clamping block 153 to move; the triggering component includes an annular guide plate 155, a stepper motor 157, a worm 158 and a worm wheel 159. The annular guide plate 155 is rotatably connected to the front side of the inner side of the annular plate 15. Four slotted holes 156 are evenly spaced on the front side of the annular guide plate 155. The inner sides of the four slotted holes 156 are slidably connected to the rear ends of the four arc-shaped clamping blocks 153 respectively. When the slotted holes 156 rotate, they can drive the arc-shaped clamping blocks 153 to move inward. The worm wheel 159 is fixedly mounted on the rear side of the annular guide plate 155. The worm 158 is rotatably connected to the upper front side of the annular plate 15. The worm 158 meshes with the worm wheel 159. The stepper motor 157 is installed on the upper left side inside the n-type seat 2. The output shaft end of the stepper motor 157 is fixedly connected to the left end of the worm 158.

[0036] Initially, the nozzle 5 is connected to the machine that discharges cutting fluid. First, the operator places the bolt into the placement ring 7, ensuring the bolt is within the annular plate 15 and between the four arc-shaped clamps 153. The head of the bolt aligns with the electric drill bit 3. Then, the drive motor 14 is started, causing the drive screw 141 to rotate forward. The forward rotation of the drive screw 141 moves the L-shaped grid plate 9 upward, which in turn moves the frame 10 upward. The upward movement of the frame 10 then moves the positioning plate 11 upward. When the positioning plate 11 moves to the left and right sides of the head of the screw, the drive motor 14 is turned off. The drive screw 141 stops moving the L-shaped grid plate 9 upward, and the positioning plate 11 stops moving upward. Then, the dual-axis motor 12 is started, driving the left and right drive screws. 13 rotates forward, and the left and right drive screws 13 rotate forward, causing the left and right positioning plates 11 to move closer to each other. The positioning plates 11 move and contact the head of the bolt, and the positioning plates 11 correct and position the head of the bolt, so that the opening position of the bolt is perpendicular to the electric drill bit 3. The dual-axis motor 12 is turned off, and the drive screw 13 stops moving the positioning plates 11. Then the stepper motor 157 is started to drive the worm gear 158 to rotate forward. The worm gear 158 rotates forward, which drives the worm wheel 159 to rotate forward. The worm wheel 159 rotates forward, which drives the annular guide plate 155 to rotate forward. The annular guide plate 155 rotates forward, which drives the slotted hole 156 to rotate forward. Since the magnetic ring 154 attracts the rotating ring 151 by magnetic force, the rotating ring 151 is connected to the arc-shaped clamp 15 by the guide rod 152. 3. Initially, there will be no rotation. When the slotted hole 156 rotates clockwise, it drives the four arc-shaped clamping blocks 153 to move closer to each other. The arc-shaped clamping blocks 153 move and contact the bolt, clamping and fixing the bolt. When the stepper motor 157 is turned off, the worm gear 158 stops driving the worm wheel 159 to rotate clockwise, and the arc-shaped clamping blocks 153 stop moving. Then, the electric drill bit 3 can be started and moved to the right to cut and open the bolt head after the alignment and positioning. At the same time, the nozzle 5 on the electric drill bit 3 sprays cutting fluid onto the bolt. The electric drill bit 3 continues to cut and open the bolt head using the cutting fluid. The used cutting fluid and the debris from the opening fall downwards through the opening of the worktable 1 and fall into the collection frame 6 for collection. When the bolt head is cut and opened on one side... This causes the nozzle 5 to stop spraying cutting fluid, and simultaneously the electric drill bit 3 moves to the left to reset and disengage from the bolt head. At this point, the dual-axis motor 12 is started, driving the drive screw 13 to reverse. The reverse rotation of the drive screw 13 causes the left and right positioning plates 11 to move away from each other and reset. The positioning plates 11 reset and disengage from the bolt head. Then, the drive motor 14 is started, driving the drive screw 141 to reverse. The reverse rotation of the drive screw 141 causes the L-shaped grid plate 9 to move downward and reset. The reset of the L-shaped grid plate 9, through the frame 10, causes the positioning plate 11 to move downward and reset. At this point, the stepper motor 157 is started, driving the worm gear 158 to rotate forward. Since the arc-shaped clamping block 153 clamps and fixes the bolt, the annular guide plate 155 drives the arc-shaped clamping block 153 to rotate forward through the slotted hole 156.The arc-shaped clamp 153 rotates clockwise, driving the rotating ring 151 to rotate clockwise via the guide rod 152. The rotating ring 151 rotates freely within the magnetic ring 154. The clockwise rotation of the arc-shaped clamp 153 also drives the bolt to rotate clockwise. When the bolt rotates 60 degrees clockwise, the stepper motor 157 is turned off, and the arc-shaped clamp 153 stops driving the bolt to rotate clockwise. The next hole opening position on the bolt head corresponds to the electric drill bit 3, and the position of the hole on the bolt corresponds to the chamfering machine 4. Then, the electric drill bit 3 is restarted again to cut and open the bolt head, while the chamfering machine 4 is started to chamfer the bolt hole position using cutting fluid. After the hole in the bolt head is chamfered, the chamfering machine 4 is started to move and reset. This process is repeated to continuously cut and open the bolt head. The drill bit 3 and chamfering machine 4 are turned off after drilling holes on all six sides of the bolt head. The stepper motor 157 is then started, driving the worm gear 158 to reverse. The worm gear 158 reverses, driving the worm wheel 159 to reverse, which in turn drives the annular guide plate 155 to reverse. The annular guide plate 155, through the slotted hole 156, moves the four arc-shaped clamping blocks 153 away from each other, resetting them. The resetting of the arc-shaped clamping blocks 153 loosens the bolt, allowing the operator to remove the drilled bolt from the placement ring 7. The collection frame 6 is then removed from the worktable 1 to drain the cutting fluid and debris. After all the cutting fluid and debris have been drained, the collection frame 6 is returned to the worktable 1. Thus, through the positioning plate 11, the bolt head is first corrected and positioned, ensuring that the bolt hole is cut perpendicular to the electric drill bit 3, preventing deviations in the bolt head position from affecting the drilling accuracy.

[0037] Please see Figure 7 and Figure 8 As shown, the head cutting and hole-opening device for fastener production also includes a limiting component installed on the L-shaped grid plate 9. The limiting component includes a fixed frame 16, a bidirectional lead screw 161, a correction plate 162, a servo motor 163, and a guide rod 164. The fixed frame 16 is fixedly connected to the front side of the bottom of the L-shaped grid plate 9. The guide rod 164 is fixedly connected to the left side of the fixed frame 16. The correction plate 162 is symmetrically slidably mounted on the guide rod 164. The correction plate 162 is located between the left and right positioning plates 11. When the correction plate 162 moves and contacts the head of the bolt, the correction plate 162 can limit the front and rear sides of the bolt head. The bidirectional lead screw 161 is rotatably connected to the right side of the front side of the fixed frame 16. The threads on the front and rear sides of the bidirectional lead screw 161 are opposite. The bidirectional lead screw 161 is threadedly connected to the right side of the correction plates 162 on the front and rear sides. The servo motor 163 is installed inside the fixed frame 16. The output shaft end of the servo motor 163 is fixedly connected to the rear end of the bidirectional lead screw 161.

[0038] Please see Figures 9-11As shown, the head cutting and drilling device for fastener production also includes a detection assembly mounted on the n-type seat 2. The detection assembly includes a rodless cylinder 17, a drilling plate 171, a guide plate 172, a receiving frame 173, a clamping assembly, an electric push rod 178, and a cutter 179. The rodless cylinder 17 is fixedly connected to the right side of the top of the n-type seat 2. The rodless cylinder 17 is inclined. The drilling plate 171 is fixedly connected to the moving part of the rodless cylinder 17. The drilling plate 171 can place the detection rod. The clamping assembly is provided on the drilling plate 171. When the clamping assembly operates, it can clamp and fix the detection rod. The guide plate 172 is fixedly connected to the lower part of the rodless cylinder 17. The guide plate 172 can guide the detection rod. The receiving frame 173 is fixedly connected to the upper right side of the front side of the n-type seat 2. The receiving frame 173 is located below the guide plate 172. 3. The cut detection rods can be collected. An electric push rod 178 is fixedly connected to the lower front side of the rodless cylinder 17. A cutter 179 is fixedly connected to the end of the telescopic rod of the electric push rod 178. The cutter 179 is located below the guide plate 172. When the cutter 179 moves, it can cut the detection rod. The clamping assembly includes an annular mounting plate 174, a movable rod 175, a clamping frame 176, and a connecting spring 177. An annular mounting plate 174 is fixedly connected to the top center of the perforated plate 171. Movable rods 175 are symmetrically slidably connected to the annular mounting plate 174. The ends of the movable rods 175 on both sides that are close to each other are fixedly connected to the clamping frames 176. The clamping frames 176 can clamp and fix the detection rod. The sides of the clamping frames 176 that are far apart from each other are connected to the inner side of the annular mounting plate 174 by a connecting spring 177.

[0039] When the L-shaped grid plate 9 moves upward, driving the positioning plate 11 upward through the frame 10, the L-shaped grid plate 9 also drives the fixed frame 16 upward. The upward movement of the fixed frame 16 drives the straightening plate 162 upward through the guide rod 164. The straightening plate 162 moves upward to the front and rear sides of the bolt head. When the positioning plate 11 moves to the left and right sides of the bolt head, the L-shaped grid plate 9 stops driving the positioning plate 11 upward through the frame 10, and the L-shaped grid plate 9 stops driving the fixed frame 16 upward. The fixed frame 16 stops driving the straightening plate 162 upward through the guide rod 164. Then, the servo motor 163 is started to drive the bidirectional lead screw 161 to rotate forward. The forward rotation of the bidirectional lead screw 161 drives the front and rear straightening plates 162 to move closer to each other. The movement of the front and rear straightening plates 162 pushes the bolt head longitudinally. The movement of the bolt head, or the correction and positioning of the bolt head, ensures that its longitudinal position corresponds precisely to the electric drill bit 3. The servo motor 163 is then turned off, and the bidirectional lead screw 161 stops moving the front and rear correction plates 162. When the left and right positioning plates 11 move away from each other to reset, they disengage from the bolt. At this point, the servo motor 163 is activated, causing the bidirectional lead screw 161 to reverse direction. This reverse rotation moves the front and rear correction plates 162 away from each other to reset, disengaging them from the bolt head. When the L-shaped grid plate 9 moves downwards, it drives the positioning plate 11 downwards via the frame 10. Simultaneously, the L-shaped grid plate 9, through the fixed frame 16, drives the guide rod 164 downwards to reset, which in turn drives the correction plate 162 downwards to reset. This prevents deviations in the longitudinal position of the bolt head from affecting the accuracy of the hole cutting, thereby further improving the precision of the bolt head cutting hole.

[0040] After the bolts are in place, pull the left and right movable rods 175 to move them away from each other. The movable rods 175 cause the left and right clamping frames 176 to move away from each other, compressing the connecting spring 177. When the clamping frames 176 reach their maximum stroke, stop pulling the movable rods 175. The coated detection rod can then be passed between the perforated plate 171 and the guide plate 172. Release the movable rods 175. Due to the action of the connecting spring 177, the left and right clamping frames 176 move towards each other, clamping... The clamping frame 176 moves the left and right movable rods 175 closer together, bringing the clamping frame 176 into contact with the detection rod. The left and right clamping frames 176 clamp and fix the detection rod. Subsequently, whenever the bolt head hole is chamfered and rotated to correspond with the detection rod, the rodless cylinder 17 is activated, moving the opening plate 171 to the lower left. The opening plate 171, through the movable rod 175, moves the clamping frame 176 to the lower left, which in turn moves the detection rod to the lower left, inserting it into the bolt hole. Inside the hole, when the detection rod moves to the appropriate position, the rodless cylinder 17 is activated, driving the opening plate 171 to move upward and to the right. This upward and to the right movement of the opening plate 171, via the clamping frame 176, causes the detection rod to move upward and to the right. When the detection rod returns to its original position, the electric push rod 178 is activated. The extension rod of the electric push rod 178 extends, driving the cutter 179 forward. The cutter 179 cuts the portion of the detection rod inserted into the bolt hole. The cut detection rod falls downward into the receiving frame 173. Then, the operation... The operator can then remove the cut-off inspection rod from the receiving frame 173 for inspection. If there are scratches on the inspection rod, it indicates that there are burrs in the hole of the bolt head, and the hole of the bolt head needs to be treated. Otherwise, it is acceptable. Each time a section of the inspection rod is cut off, the rodless cylinder 17 is activated to move the hole-opening plate 171 to the lower left, causing the inspection rod to move a certain distance to the lower left. This process is repeated. Each time the bolt hole is chamfered and rotated to correspond with the inspection rod, the inspection rod can inspect the quality of the hole of the bolt head. When an inspection rod is cut to the point of being unusable, the movable rods 175 on both sides can be pulled to move away from each other, causing the clamping frame 176 to release the remaining inspection rod. The inspection rod falls downwards, and the fallen inspection rod can be collected and disposed of. This prevents the unqualified quality of the hole opened in the bolt head from affecting subsequent use, thereby ensuring the quality of the bolt head hole.

[0041] Please see Figure 12 As shown, the head cutting and hole-opening device for fastener production also includes a spiral strip 18 and a filter frame 19. The spiral strip 18 is fixed to the upper inner side of the collection frame 6, and the filter frame 19 is placed on the upper inner side of the collection frame 6. The filter frame 19 is in contact with the top of the spiral strip 18, and the filter frame 19 can filter the debris in the cutting fluid.

[0042] When the used cutting fluid and debris fall through the opening of the workbench 1, they first fall into the filter frame 19, which filters the debris, trapping it inside. The cutting fluid then passes through the filter frame 19 and falls into the collection frame 6 for collection. After all the bolt heads have been cut, the collection frame 6 is removed from the workbench 1, and the filter frame 19 is removed from it, separating it from the U-shaped strip 18. The debris in the filter frame 19 is then emptied, and the cutting fluid in the collection frame 6 is also emptied. The filter frame 19 is then placed back into the collection frame 6, where it is now in contact with the U-shaped strip 18 and its contact is restricted. Finally, the collection frame 6 is placed back onto the workbench 1. This process prevents the cutting fluid and debris from mixing and affecting subsequent recycling, thus ensuring the proper recycling of the cutting fluid.
