The punching of the bolt head can meet subsequent assembly, function expansion, or marking requirements.

[0003] Chinese Patent with Publication No. CN114769658B discloses a screw head punching device and its punching method for bolt production. Above the bracket, a first hydraulic jack is installed, and the first hydraulic jack is fixedly connected to the bracket by bolts. The lifting end of the first hydraulic jack is installed with a lifting device, and the lifting device is fixedly connected to the first hydraulic jack by fastening screws. One side of the lifting device is provided with a slide bar with engaging teeth, and the slide bar with engaging teeth is slidably connected to the lifting device. One side of the slide bar with engaging teeth is installed with a first rotating box, and the first rotating box is fixedly connected to the slide bar with engaging teeth by fastening screws. A first drill bit is installed on one side of the first rotating box. Although the above patent can punch the head of the bolt as a fastener, when the operator places the bolt in a fixed position, due to the placement error of manual operation, the punching position of the bolt and the drill bit are not perpendicular, resulting in a deviation between the punching position of the bolt and the drill bit, affecting the accuracy of punching.

[0004] The present invention aims to solve the problems existing in the above patent. For this purpose, a head cutting and punching device for fastener production is proposed, which can correct the position of the bolt head, make the punching position of the bolt perpendicular to the drill bit, and improve the punching accuracy. Summary of the Invention

[0005] In order to overcome the defect that when the operator places the bolt in a fixed position, due to the placement error of manual operation, the punching position of the bolt and the drill bit are not perpendicular, resulting in a deviation between the punching position of the bolt and the drill bit, affecting the accuracy of punching, the present invention provides a head cutting and punching device for fastener production, which can correct the position of the bolt head, make the punching position of the bolt perpendicular to the drill bit, and improve the punching accuracy.

[0011] Further description, the head cutting and opening device for fastener production further includes a detection component. The detection component includes a rodless cylinder fixedly connected to the n-shaped seat. The rodless cylinder is inclined. An opening plate is fixedly connected to the moving part of the rodless cylinder, which is used to place the detection rod.

[0014] The beneficial effects of the present invention are as follows: 1. First, place the bolt into the placement ring. Then start the driving motor to drive the driving screw to rotate forward, so that the L-shaped grid plate drives the positioning plate to move upward to the left and right sides of the bolt through the frame body. Then start the double-shaft motor to drive the driving screw to rotate forward. The driving screw drives the positioning plates on the left and right sides to move into contact with the head of the bolt, thus performing deviation correction and positioning on the head of the bolt, making the position where the head of the screw needs to be opened perpendicular to the electric drill bit. Then start the electric drill bit to cut and open the head of the bolt after deviation correction and positioning, so as to prevent the deviation of the position of the bolt head from affecting the opening, thereby improving the accuracy of the opening.

[0015] 2. Under the action of the deviation correction plate, whenever the positioning plate corrects and positions the left and right sides of the bolt head, the deviation correction plate can correct and position the front and back sides of the bolt, so that the longitudinal position of the bolt head is in an accurate position. In this way, it is possible to prevent the deviation of the longitudinal position of the bolt head from affecting the accuracy of the hole opening, thereby further improving the accuracy of the cutting hole opening of the bolt head.

[0016] 3. Under the action of the detection rod, whenever the hole chamfer of the bolt head corresponds to the detection rod, the detection rod can move into the hole of the bolt head for detection. Subsequently, the detection rod moves back to its original position and is cut by the cutting tool. By checking the appearance of the detection rod, it is possible to know whether the quality of the hole of the bolt head is qualified. In this way, it is possible to prevent the unqualified quality of the hole opened by the bolt head from affecting the subsequent use, thereby ensuring the quality of the hole of the bolt head.

An opening for debris and cutting fluid to pass through is provided on the front side of the top of the workbench 1. An embedding ring 7 is fixedly connected to the upper part of the front side of the n-shaped seat 2. The embedding ring 7 can be used to place bolts.

The output shaft ends on the left and right sides of the double-shaft motor 12 are respectively fixedly connected to the ends of the driving lead screws 13 on the left and right sides. The double-shaft motor 12 is used to drive the driving lead screws 13 to rotate. The driving lead screws 13 drive the positioning plates 11 to move inwards to contact the bolt head, so that the positioning plates 11 can correct the deviation of the bolt head and be perpendicular to the electric drill bit 3. A driving component is arranged on the U-shaped plate 8. The driving component is used to drive the L-shaped grid plate 9 to move upwards. A clamping component is arranged on the n-shaped seat 2. When the clamping component operates, the clamping component can clamp and fix the bolt.

[0032] Please refer to Figure 3 As shown in the figure, the driving component includes a driving motor 14 and a driving screw 141. A driving screw 141 is rotatably inserted through the middle of the bottom of the U-shaped plate 8. The driving screw 141 is threadedly connected to the rear side of the L-shaped grid plate 9. When the driving screw 141 rotates, the driving screw 141 can drive the L-shaped grid plate 9 to move up and down. A driving motor 14 is installed on the outer bottom of the U-shaped plate 8. The output shaft end of the driving motor 14 is fixedly connected to the bottom end of the driving screw 141.

[0033] Please refer to Figures 4-6As shown, the clamping assembly includes an annular plate 15, a rotating ring 151, guide rods 152, arc-shaped clamping blocks 153, a magnetic ring 154 and a trigger assembly. An annular plate 15 is fixedly connected to the middle of the upper part of the n-shaped seat 2 in an embedded manner. The annular plate 15 corresponds exactly to the placing ring 7. The front side of the annular plate 15 is rotatably connected to a rotating ring 151 in the circumferential direction. Four guide rods 152 are slidably inserted through the rotating ring 151 at equal intervals in the circumferential direction. Arc-shaped clamping blocks 153 are fixedly connected to the ends of the four guide rods 152 close to each other. When the arc-shaped clamping blocks 153 move inwards and contact the bolt, the arc-shaped clamping blocks 153 can clamp and fix the bolt. A magnetic ring 154 is fixedly connected to the front side of the outer surface of the annular plate 15 in the circumferential direction. The inner side surface of the magnetic ring 154 is in magnetic contact with the outer side surface of the rotating ring 151. A trigger assembly is arranged between the n-shaped seat 2 and the annular plate 15. When the trigger assembly operates, the trigger assembly can drive the arc-shaped clamping blocks 153 to move. The trigger assembly includes an annular guide plate 155, a stepping motor 157, a worm 158 and a worm gear 159. The front side of the inner surface of the annular plate 15 is rotatably connected to an annular guide plate 155 in the circumferential direction. Four straight slots 156 are evenly spaced in the circumferential direction on the front side of the annular guide plate 155. The inner sides of the four straight slots 156 are respectively slidably connected to the rear ends of the four arc-shaped clamping blocks 153. When the straight slots 156 rotate, the straight slots 156 can drive the arc-shaped clamping blocks 153 to move inwards. A worm gear 159 is fixedly sleeved on the rear side of the annular guide plate 155 in the circumferential direction. A worm 158 is horizontally rotatably inserted through the front side of the upper part of the annular plate 15. The worm 158 meshes with the worm gear 159. A stepping motor 157 is installed on the upper left side inside the n-shaped seat 2. The end of the output shaft of the stepping motor 157 is fixedly connected to the left end of the worm 158.

[0034] Initially, the nozzle 5 is externally connected to a machine for discharging cutting fluid. First, the operator places the bolt into the placement ring 7, and the bolt is located within the annular plate 15 and also between the four arc-shaped clamping blocks 153. The head of the bolt corresponds to the electric drill bit 3. Then, the driving motor 14 is started to drive the driving screw rod 141 to rotate forward. The forward rotation of the driving screw rod 141 drives the L-shaped grid plate 9 to move upward. The upward movement of the L-shaped grid plate 9 drives the frame 10 to move upward. The upward movement of the frame 10 drives the positioning plate 11 to move upward. When the positioning plate 11 moves to the left and right sides of the head of the screw rod, the driving motor 14 is turned off, and the driving screw rod 141 stops driving the L-shaped grid plate 9 to move upward, and the positioning plate 11 stops moving upward. Then, the double-shaft motor 12 is started to drive the left and right driving screw rods 13 to rotate forward. The forward rotation of the left and right driving screw rods 13 drives the left and right positioning plates 11 to move towards each other. The left and right positioning plates 11 move into contact with the head of the bolt, and the positioning plate 11 corrects and positions the head of the bolt, so that the opening position of the bolt is perpendicular to the electric drill bit 3. The double-shaft motor 12 is turned off, and the driving screw rod 13 stops driving the positioning plate 11 to move. Then, the stepping motor 157 is started to drive the worm 158 to rotate forward. The forward rotation of the worm 158 drives the worm gear 159 to rotate forward. The forward rotation of the worm gear 159 drives the annular guide plate 155 to rotate forward. The forward rotation of the annular guide plate 155 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 makes the arc-shaped clamping blocks 153 not rotate first through the guide rod 152. The forward rotation of the slotted hole 156 drives the four arc-shaped clamping blocks 153 to move towards each other. The arc-shaped clamping blocks 153 move into contact with the bolt, and the four arc-shaped clamping blocks 153 clamp and fix the bolt. The stepping motor 157 is turned off, the worm 158 stops driving the worm gear 159 to rotate forward, and the arc-shaped clamping blocks 153 stop moving. Then, the electric drill bit 3 can be started to move to the right to cut and open the head of the bolt after deviation correction and positioning. At the same time, the nozzle 5 on the electric drill bit 3 sprays the cutting fluid onto the bolt, and the electric drill bit 3 continues to cut and open the head of the bolt through the cutting fluid. The used cutting fluid and the chips generated by the opening fall downward through the opening of the workbench 1 and fall into the collection box 6 for collection. When one side of the head of the bolt is cut and opened, the nozzle 5 stops spraying the cutting fluid. At the same time, the electric drill bit 3 moves to the left to reset and disengages from the head of the bolt. At this time, the double-shaft motor 12 is started to drive the driving screw rod 13 to reverse. The reverse rotation of the driving screw rod 13 drives the left and right positioning plates 11 to move away from each other and reset. The positioning plate 11 resets and disengages from the head of the bolt. Then, the driving motor 14 is started to drive the driving screw rod 141 to reverse. The reverse rotation of the driving screw rod 141 drives the L-shaped grid plate 9 to move downward to reset. The reset of the L-shaped grid plate 9 drives the positioning plate 11 to move downward to reset through the frame 10. At this time, the stepping motor 157 is continued to be started to drive the worm 158 to rotate forward. Since the arc-shaped clamping blocks 153 clamp and fix the bolt, the annular guide plate 155 drives the arc-shaped clamping blocks 153 to rotate forward through the slotted hole 156.The forward rotation of the arc-shaped clamping block 153 drives the forward rotation of the rotating ring 151 through the guide rod 152. The forward rotation of the rotating ring 151 idles within the magnetic ring 154. The forward rotation of the arc-shaped clamping block 153 also drives the forward rotation of the bolt. When the bolt rotates forward by sixty degrees, the stepping motor 157 is turned off, and the arc-shaped clamping block 153 stops driving the forward rotation of the bolt. The next opening position of the bolt head corresponds to the electric drill 3, and the position where the hole is drilled on the bolt corresponds exactly to the chamfering machine 4. Then, start the electric drill 3 again according to the above operation to cut and open the bolt head. At the same time, start the chamfering machine 4 to chamfer the hole position of the bolt through the cutting fluid. After the chamfering of the hole in the bolt head is completed, start the chamfering machine 4 to move and reset. Repeating this way, the bolt head can be continuously cut and opened, and the hole position of the bolt can also be chamfered. When the six sides of the bolt head are all opened, turn off the electric drill 3 and the chamfering machine 4, and start the stepping motor 157 to drive the reverse rotation of the worm 158. The reverse rotation of the worm 158 drives the reverse rotation of the worm gear 159. The reverse rotation of the worm gear 159 drives the reverse rotation of the annular guide plate 155. The reverse rotation of the annular guide plate 155 drives the four arc-shaped clamping blocks 153 to move and reset in the direction away from each other through the slotted hole 156. When the arc-shaped clamping block 153 resets, the bolt is loosened, and the operator can take out the bolt with the hole from the placing ring 7, and take out the collecting frame 6 from the workbench 1 to pour out the cutting fluid and debris. After all the cutting fluid and debris are poured out, put the collecting frame 6 back into the workbench 1. In this way, through the function of the positioning plate 11, the deviation of the bolt head can be corrected and positioned first, so that the opening position of the bolt is perpendicular to the electric drill 3 for cutting and opening, to prevent the deviation of the bolt head position from affecting the opening, thereby improving the accuracy of the opening.,

[0035] Please refer to Figure 7 and Figure 8 As shown in the figure, the head cutting and opening device for fastener production further 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 deviation-correcting plate 162, a servo motor 163 and a guide rod 164. The fixed frame 16 is fixedly connected to the front side of the inner 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 deviation-correcting plates 162 are symmetrically and slidably sleeved on the front and rear of the guide rod 164. The deviation-correcting plates 162 are located between the positioning plates 11 on the left and right sides. When the deviation-correcting plates 162 move and contact the head of the bolt, the deviation-correcting plates 162 can limit the front and rear sides of the head of the bolt. The bidirectional lead screw 161 is rotatably inserted through the right side of the front surface 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 sides of the front and rear deviation-correcting plates 162. The servo motor 163 is installed inside the fixed frame 16. The end of the output shaft of the servo motor 163 is fixedly connected to the rear end of the bidirectional lead screw 161.

[0036] Please refer to Figures 9-11As shown, the head cutting and opening device for fastener production further includes a detection component installed on the n-shaped seat 2. The detection component includes a rodless cylinder 17, an opening plate 171, a guide plate 172, a material receiving frame 173, a clamping component, an electric push rod 178, and a cutting tool 179. A rodless cylinder 17 is fixedly connected to the right side of the outer top of the n-shaped seat 2. The rodless cylinder 17 is inclined. An opening plate 171 is fixedly connected to the moving part of the rodless cylinder 17. The opening plate 171 can be used to place the detection rod. A clamping component is arranged on the opening plate 171. When the clamping component operates, the clamping component can clamp and fix the detection rod. A guide plate 172 is fixedly connected to the lower part of the rodless cylinder 17. The guide plate 172 can guide the detection rod. A material receiving frame 173 is fixedly connected to the upper right side of the front side of the n-shaped seat 2. The material receiving frame 173 is located below the guide plate 172. The material receiving frame 173 can collect the cut detection rods. An electric push rod 178 is fixedly connected through the lower part of the front side of the rodless cylinder 17. The end of the telescopic rod of the electric push rod 178 is fixedly connected to a cutting tool 179. The cutting tool 179 is located below the guide plate 172. When the cutting tool 179 moves, the cutting tool 179 can cut the detection rod. The clamping component 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 middle of the top of the opening plate 171. Movable rods 175 are slidably connected through the annular mounting plate 174 symmetrically from left to right. Clamping frames 176 are fixedly connected to the ends of the movable rods 175 on both sides close to each other. The clamping frames 176 can clamp and fix the detection rod. Connecting springs 177 are connected between the outer sides of the clamping frames 176 on both sides away from each other and the inner side of the annular mounting plate 174.

[0037] When the L-shaped grid plate 9 moves upward through the frame 10 to drive the positioning plate 11 to move upward, the L-shaped grid plate 9 also drives the fixed frame 16 to move upward. The upward movement of the fixed frame 16 drives the deviation rectifying plate 162 to move upward through the guide rod 164. The deviation rectifying plate 162 moves upward to be on both sides of the front and back of the bolt head. When the positioning plate 11 moves to both sides of the left and right of the bolt head, the L-shaped grid plate 9 stops driving the positioning plate 11 to move upward through the frame 10. The L-shaped grid plate 9 stops driving the fixed frame 16 to move upward. The fixed frame 16 stops driving the deviation rectifying plate 162 to move upward through the guide rod 164. Subsequently, 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 deviation rectifying plates 162 on both sides to move towards each other. The movement of the deviation rectifying plates 162 on both sides pushes the head of the bolt to move longitudinally, thereby rectifying and positioning the head of the bolt, making the longitudinal position of the bolt head correspond exactly to the electric drill bit 3. The servo motor 163 is turned off, and the bidirectional lead screw 161 stops driving the deviation rectifying plates 162 on both sides to move. When the positioning plates 11 on both sides move away from each other and reset, the positioning plates 11 are disengaged from contact with the bolt. At this time, the servo motor 163 is started to drive the bidirectional lead screw 161 to rotate in reverse. The reverse rotation of the bidirectional lead screw 161 drives the deviation rectifying plates 162 on both sides to move away from each other and reset. The deviation rectifying plate 162 resets and is disengaged from contact with the head of the bolt. When the L-shaped grid plate 9 moves downward through the frame 10 to drive the positioning plate 11 to move downward and reset, the L-shaped grid plate 9 also drives the guide rod 164 to move downward and reset through the fixed frame 16. The downward movement and reset of the guide rod 164 drive the deviation rectifying plate 162 to move downward and reset. In this way, it is possible to prevent the longitudinal position of the bolt head from deviating and affecting the accuracy of the hole opening, thereby further improving the accuracy of the cutting and hole opening of the bolt head.

[0038] After the bolt is placed, pull the movable rods 175 on the left and right sides to move away from each other. The movable rods 175 drive the clamping frames 176 on the left and right sides to move away from each other, and the connecting springs 177 are compressed. When the clamping frames 176 move to the maximum stroke, stop pulling the movable rods 175. Then, the detection rod coated with the coating can be passed through between the opening plate 171 and the guide plate 172. Release the movable rods 175. Due to the action of the connecting springs 177, the clamping frames 176 on the left and right sides move towards each other. The clamping frames 176 drive the movable rods 175 on the left and right sides to move towards each other. The clamping frames 176 move and contact the detection rod, and the clamping frames 176 on the left and right sides clamp and fix the detection rod. Subsequently, whenever the chamfered hole in the bolt head rotates to correspond to the detection rod, start the rodless cylinder 17 to drive the opening plate 171 to move left and downward. The opening plate 171 drives the clamping frame 176 to move left and downward through the movable rod 175. The clamping frame 176 drives the detection rod to move left and downward. The detection rod moves left and downward and inserts into the hole of the bolt. When the detection rod moves to a suitable position, start the rodless cylinder 17 to drive the opening plate 171 to move right and upward. The opening plate 171 moves right and upward and drives the detection rod to move right and upward through the clamping frame 176. When the detection rod moves right and upward to reset, start the electric push rod 178. The telescopic rod of the electric push rod 178 extends and drives the cutter 179 to move forward. The cutter 179 moves forward to cut the part of the detection rod inserted into the hole of the bolt. The cut detection rod drops downward into the material receiving frame 173. Then, the operator can take out the cut detection rod from the material receiving frame 173 for inspection. If there are scratches on the detection rod, it means there are burrs in the hole of the bolt head, and the hole of the bolt head needs to be processed. Otherwise, it is qualified. Whenever a section of the detection rod is cut off, start the rodless cylinder 17 to drive the opening plate 171 to move left and downward, so that the detection rod moves left and downward for a certain distance. Repeat this process. Whenever the chamfered hole of the bolt rotates to be directly corresponding to the detection rod, the detection rod can detect the quality of the hole in the bolt head. When a detection rod is cut to be unusable, pull the movable rods 175 on the left and right sides to move away from each other to drive the clamping frames 176 to release the remaining detection rod. The detection rod drops downward, and the dropped detection rod can be collected and processed. In this way, it can prevent the unqualified quality of the holes opened in the bolt head from affecting subsequent use, thus ensuring the quality of the holes in the bolt head.

[0039] Please refer to Figure 12 As shown, the head cutting and opening device for fastener production further includes a return strip 18 and a filter frame 19. The upper part inside the collection frame 6 is fixedly connected with a return strip 18. A filter frame 19 is placed on the upper part inside the collection frame 6. The filter frame 19 contacts the top of the return strip 18. The filter frame 19 can filter the debris in the cutting fluid.

[0040] When the used cutting fluid and debris fall downward through the opening of the workbench 1, the cutting fluid and debris first fall into the filter box 19. The filter box 19 filters the debris, and the debris is filtered inside the filter box 19, while the cutting fluid passes through the filter box 19 and falls into the collection box 6 for collection. After the cutting of the bolt heads is completed, the collection box 6 is removed from the workbench 1, and then the filter box 19 is taken out from the collection box 6. The filter box 19 is disengaged from the return strip 18, and the debris in the filter box 19 is poured out for disposal. At the same time, the cutting fluid in the collection box 6 is poured out for disposal. Then the filter box 19 is put back into the collection box 6, and the filter box 19 contacts the return strip 18 and is limited. Finally, the collection box 6 is put back on the workbench 1. In this way, it is possible to prevent the cutting fluid and debris from being mixed together, which affects the subsequent recycling, thereby ensuring the normal subsequent recycling of the cutting fluid.
