DETAILED DESCRIPTION

[0033] 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.

[0034] like Figures 1 to 11 As shown, the present invention provides a technical solution: a stainless steel bolt tapping machine, comprising a base plate 1, a support frame 2 is fixedly connected to the top surface of the base plate 1, a telescopic cylinder 4 is fixedly installed on the top of the support frame 2, an inner hollow wheel disc 3 is fixedly connected to the output end of the telescopic cylinder 4, four tapping taps 8 are rotatably connected to the inner wall of the bottom surface of the inner hollow wheel disc 3, a power component is arranged inside the inner hollow wheel disc 3, the power component is used to drive the four tapping taps 8 to rotate, stainless steel bolts to be tapped are placed directly below the four tapping taps 8, a clamping component is arranged on one side of the stainless steel bolts, the clamping component is used to clamp the four stainless steel bolts, a feeding component is arranged at the bottom of the stainless steel bolts, the feeding component is used to feed and collect the stainless steel bolts after processing.

[0035] During operation: When the current device is tapping bolts, although an automatic tapping processing method is used to improve the work efficiency of the tapping process, the bolts after tapping need to be taken out by other means. The process requires additional manpower and may cause the production line to stagnate or slow down, thereby reducing production efficiency and increasing labor costs. Through the embodiment of this scheme, when it is used specifically, four stainless steel bolts are first placed directly below the four tapping taps 8. It should be noted that the stainless steel bolts of the same batch are of the same size. The four stainless steel bolts are clamped at the same time by the clamping assembly to fix their positions, and then the telescopic cylinder 4 is started to drive the inner hollow wheel disc 3 and the four tapping taps 8 to descend. During the descent, the power assembly is started to drive the four tapping taps 8 to rotate at the same time. , achieving the tapping effect, the clamping component ensures that the four tapping cones 8 will not drive the stainless steel bolts to rotate during the downward rotation for tapping, and the clamping component is applicable to different batches of stainless steel bolts of different sizes. After the tapping is completed, the four tapping cones 8 rotate in the opposite direction to withdraw the thread, and then the clamping component is relaxed. During the relaxation process, the blanking component can be driven to move, so that the stainless steel bolts can automatically fall to the designated position for collection. Through the above embodiment, clamping four bolts for tapping at the same time can process more bolts at the same time, thereby improving production efficiency. At the same time, after the tapping is completed, the four bolts can be dropped to the designated position at the same time by relaxing the clamping component, further reducing the time for bolt collection and improving the overall production efficiency.

[0036] like Figures 2 to 5 As shown, the clamping assembly includes a square plate 9, and sliding grooves 12 are opened on the four inner walls of the square plate 9. The inner wall of each sliding groove 12 is symmetrically slidably connected with a sliding block 11, and one side of multiple sliding blocks 11 is fixedly connected with a clamp 10. The inner wall of the clamp 10 is provided with a driving assembly, which is used to simultaneously drive each group of clamps 10 to move closer or farther away from each other.

[0037] During operation: after placing the four bolts at the designated positions, start the driving assembly, which will drive the two clamps 10 on each side of the square plate 9 to approach each other. When the two clamps 10 touch the bolts, the bolts are clamped. After the tapping is completed, the driving assembly will drive the two clamps 10 of each group to move away from each other and relax them to facilitate the removal of the bolts. Through the above embodiment, the clamping assembly can clamp four bolts from the same batch at the same time. When the bolts from different batches are of different sizes, the clamping assembly can still be used, thereby increasing the scope of application of the device.

[0038] like Figure 3 to Figure 4As shown, the driving assembly includes four bidirectional threaded rods 14, and the outer wall of each bidirectional threaded rod 14 is threadedly connected to the inner walls of the two clamps 10, respectively, wherein one end of two bidirectional threaded rods 14 and both ends of the other two bidirectional threaded rods 14 are fixedly connected with transmission gears 16, and each two transmission gears 16 close to each other are meshed with each other through teeth, and the outer wall of each bidirectional threaded rod 14 is rotatably connected to a clamping ring 15, and each clamping ring 15 is fixedly connected to the outer side of the square plate 9, and one end of one of the bidirectional threaded rods 14 is fixedly connected to motor 2 13.

[0039] During operation: start motor 2 13, and its output shaft will drive one of the two-way threaded rods 14 to rotate, and transmit the information through the transmission gears 16 between each other, driving the four two-way threaded rods 14 to rotate at the same time. During the rotation of the two-way threaded rod 14, due to the restrictions of the sliding block 11 and the sliding groove 12, the two clamps 10 in each group will only move closer to or farther away from each other, and the position of the two-way threaded rod 14 is fixed by the clamping ring 15.

[0040] like Figure 6 to Figure 7 As shown, the material unloading assembly includes a material unloading box 19, the top surfaces and bottom surfaces of the four ends of the material unloading box 19 are all open, and the inner walls of the top surfaces of the four ends of the material unloading box 19 are symmetrically provided with placement platforms 25, and four stainless steel bolts are respectively placed directly above every two placement platforms 25. The outer wall of each placement platform 25 is fixedly connected with a slide bar 24, and the inner walls of the top surfaces of the four ends of the material unloading box 19 are provided with slide bar grooves 34, and the slide bar 24 and the slide bar grooves 34 are slidably connected and adapted to each other, and a pulling assembly is arranged above the placement platform 25. When the clamping assembly is relaxed, it will drive the pulling assembly to move each group of two placement platforms 25 away from each other.

[0041] During operation: an additional robotic arm can be set outside the device to place four bolts directly above each two placement tables 25. When the clamping assembly is relaxed, it drives the pulling assembly to move each group of two placement tables 25 away from each other. There is no force point at the bottom of the four stainless steel bolts, and the clamping force disappears. At this time, the four bolts will directly fall into the interior of the discharge box 19, achieving the effect of automatic and rapid collection.

[0042] like Figures 7 to 9 As shown, the pulling assembly includes a plurality of displacement rods 20, which are respectively inserted into the inner walls of a plurality of clamps 10, a protrusion 23 is fixedly connected to the bottom outer wall of each displacement rod 20, and a locking assembly is provided on one side of each placement platform 25.

[0043] During operation: when each two clamps 10 move closer to each other to clamp the bolt, the displacement rod 20 will drive the protrusion 23 to enter the locking assembly, and when the clamps 10 move away from each other to loosen and cancel the clamping of the bolt, the protrusion 23 will drive each two placement platforms 25 to slide away from each other through the locking assembly. When sliding to a certain position and the gap formed between the two placement platforms 25 is large enough, the bolt will fall into the inside of the discharge box 19, thereby achieving the effect of each group of two placement platforms 25 moving away from each other.

[0044] like Figures 7 to 9 As shown, the locking assembly includes a plurality of fixed plates 30, the inner wall of each fixed plate 30 is slidably connected to a plurality of connecting rods 2 31, one end of each connecting rod 2 31 is fixedly connected to a landslide block 2 33, and one side of each landslide block 2 33 and one side of the fixed plate 30 are fixedly connected to a return spring 3 32.

[0045] During operation: when the displacement rod 20 drives the protrusion 23 into the locking assembly, it will squeeze the position of the landslide block 23, so that the protrusion 23 enters the locking assembly without obstruction. After squeezing the landslide block 23, the protrusion 23 may continue to move until the clamp 10 clamps the bolt, and the landslide block 23 will be quickly reset by the reset spring 32. When every two clamps 10 cancel the clamping and slowly relax, the landslide block 23 will be driven to move by the protrusion 23. The landslide block 23 drives the placement table 25 to move through the connecting rod 231 and the fixed plate 30, so that every two placement tables 25 are moved away from each other, so that the bolt can fall into the interior of the discharge box 19. By setting a plurality of landslide blocks 23, for bolts of different sizes in different batches, the moving distances of the clamps 10 approaching each other are different, so that the position of the protrusion 23 entering the locking assembly is different, and the device can be adapted.

[0046] like Figures 7 to 9 As shown, one side of each sliding rod 24 is symmetrically fixedly connected with a connecting rod 26, and the connecting rod 26 is slidably connected to the inner wall of the discharge box 19. One end of each connecting rod 26 is fixedly connected to a limiting cone 28. The outer wall of each connecting rod 26 is provided with a return spring 27, and the two ends of each return spring 27 are respectively fixedly connected to the inner side of the discharge box 19 and one side of the placement table 25. An extrusion assembly is provided under the displacement rod 20, and the extrusion assembly is used to drive the protrusion 23 to move upward.

[0047] During operation: when the clamping component is relaxed, it drives the pulling component to move the two placement platforms 25 in each group away from each other, so that the bolts can fall and be collected. The placement platform 25 needs to be reset to prepare for the next tapping work to place the bolts. When the protrusion 23 drives the placement platform 25 to move to the maximum through the locking component, the extrusion component will drive the protrusion 23 to move upward. At this time, the protrusion 23 is separated from the landslide block 2 33, and the placement platform 25 will quickly rebound through the connecting rod 1 26 and the reset spring 2 27 to return to the initial position.

[0048] like Figures 7 to 9 As shown, the extrusion assembly includes a plurality of landslide blocks 29, each of which is fixedly mounted on the top of the discharge box 19, and a return spring 21 is provided on the outer wall of each displacement rod 20. A top button 22 is fixedly connected to the top of each displacement rod 20, and both ends of the return spring 21 are fixedly connected to the top of the clamp 10 and the bottom of the top button 22, respectively.

[0049] During operation: when the clamp 10 cancels the clamping and moves loosely to make the bolt fall off, the bottom of the displacement rod 20 will contact the landslide block 29, and the landslide block 29 will squeeze the displacement rod 20 upward, so that the protrusion 23 is separated from the landslide block 2 33. At this time, the placement table 25 will rebound to its original position, and the displacement rod 20 uses the reset spring 21 and the top button 22 to make the protrusion 23 move away from the landslide block 29. When clamping, the position of the displacement rod 20 is lowered and reset, which can ensure that the protrusion 23 can form an extrusion relationship with the landslide block 2 33 during the clamping process.

[0050] like Figure 1 to Figure 2 As shown, the bottom of the square plate 9 is fixedly connected with a support 18, and the support 18 is fixedly installed on the top of a discharge box 19. The outer wall of the discharge box 19 is fixedly connected with a bracket 17, and the bracket 17 is fixedly installed on the top of the bottom plate 1. A collecting box 35 is provided at the bottom opening of the discharge box 19, and the collecting box 35 is placed directly above the bottom plate 1.

[0051] During operation: the positions of the material discharge box 19 and the square plate 9 are fixed by the bracket 17 and the support 18, and at the same time, the bolts dropped into the material discharge box 19 will fall into the collection box 35, so as to achieve the effect of unified collection.

[0052] like Figure 10 to Figure 11 As shown, the power assembly includes a motor 5, which is fixedly installed at the bottom of the inner hollow wheel disc 3. The output shaft of the motor 5 is fixedly connected to a gear disc 6, and the teeth of the gear disc 6 are meshed with four driven gears 7. The four driven gears 7 are fixedly connected to the tops of four tapping cones 8 respectively.

[0053] During operation: when the telescopic cylinder 4 is started to drive the inner hollow wheel disc 3 to descend, the motor 5 is started, and its output shaft will drive the gear plate 6 to rotate, and the gear plate 6 will drive the tapping cone 8 to rotate through the driven gear 7, thereby achieving the effect of rotating the tapping cone 8 to perform tapping.

[0054] Workflow: First, an additional robotic arm is set outside the device to place four bolts directly above each two placement tables 25, and the motor 2 13 is started. Its output shaft will drive one of the two-way threaded rods 14 to rotate, and the transmission is carried out through the mutual transmission gears 16 to drive the four two-way threaded rods 14 to rotate at the same time. During the rotation of the two-way threaded rod 14, due to the restrictions of the sliding block 11 and the sliding groove 12, the two clamps 10 of each group will only move to achieve mutual proximity or distance. When the two clamps 10 contact the bolt, the bolt is clamped.

[0055] Secondly, fix the position of the bolt, and then start the telescopic cylinder 4 to drive the inner hollow wheel disc 3 and the four tapping taps 8 to descend. During the descent, start the motor 5, and its output shaft will drive the gear plate 6 to rotate. The gear plate 6 will drive the tapping tap 8 to rotate through the driven gear 7 to achieve the tapping effect. The clamping assembly ensures that the four tapping taps 8 will not drive the stainless steel bolts to rotate during the descent and rotation for tapping, and the clamping assembly can be applied to stainless steel bolts of different sizes from different batches.

[0056] Then, after the tapping is completed, the four tapping cones 8 rotate in the opposite direction to withdraw the thread, and then the clamping assembly is relaxed. When every two clamps 10 move close to each other to clamp the bolt, the displacement rod 20 will drive the protrusion 23 into the locking assembly, which will squeeze the position of the landslide block 23, so that the protrusion 23 enters the locking assembly without hindrance. After squeezing the landslide block 23, the protrusion 23 may continue to move until the clamp 10 clamps the bolt, and the landslide block 23 will be quickly reset by the reset spring 32 ... When the clamp 10 is released from clamping and slowly relaxes, the landslide block 23 will be driven to move through the protrusion 23, and the landslide block 23 will drive the placement table 25 to move through the connecting rod 231 and the fixed plate 30, so that every two placement tables 25 are away from each other, so that the bolts can fall into the interior of the discharge box 19. By setting up multiple landslide blocks 23, for bolts of different sizes in different batches, the moving distances of the clamps 10 approaching each other are different, so that the positions of the protrusions 23 entering the locking assembly are different, and the device can be adapted.

[0057] When the clamping assembly is relaxed, it drives the pulling assembly to move the two placement platforms 25 in each group away from each other, so that the bolts can fall and be collected. The placement platform 25 needs to be reset to prepare for placing the bolts for the next tapping work. When the protrusion 23 drives the placement platform 25 to move to the maximum through the locking assembly, the squeezing assembly drives the protrusion 23 to move upward. At this time, the protrusion 23 is separated from the landslide block 2 33, so that the placement platform 25 will quickly rebound through the connecting rod 1 26 and the reset spring 2 27 and return to the initial position. When the clamp 10 is released from clamping and moves loosely to cause the bolt to fall off, the bottom of the displacement rod 20 will contact the landslide block 29, and the landslide block 29 will squeeze the displacement rod 20 upward, so that the protrusion 23 is separated from the landslide block 2 33. At this time, the placement table 25 will rebound to its original position, and the displacement rod 20 will use the reset spring 21 and the top button 22 to make the protrusion 23 move away from the landslide block 29. When clamping, the position of the displacement rod 20 will be lowered and reset, which can ensure that the protrusion 23 can form an extrusion relationship with the landslide block 2 33 during the clamping process.

[0058] Finally, the bolts dropped into the discharge box 19 will fall into the collection box 35, achieving a unified collection effect.
