DETAILED DESCRIPTION

[0020] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0021] Example 1 See also Figure 1 - Figure 8A nut internal thread processing device comprises: an operating table 1; a mounting seat 2 and an air compressor 4 are installed on the operating table 1, the air compressor 4 is located behind the mounting seat 2, and a hydraulic cylinder 3 is installed in the mounting seat 2; a thread processing component 5 is used to process the internal thread of the nut, the thread processing component 5 comprises a sliding arm 51, the sliding arm 51 is slidably installed on the inner wall of the mounting seat 2, the output end of the hydraulic cylinder 3 is connected to the bottom surface of the sliding arm 51, a mounting cylinder 52 is installed through the sliding arm 51, and a wind wheel 57 is rotatably installed on the inner wall of the mounting cylinder 52, and a No. 1 air pipe 41 and a No. 2 air pipe 42 are installed on the air compressor 4. After starting the air compressor 4, the air compressor 4 can be controlled to exhaust air through the No. 1 air pipe 41 or the No. 2 air pipe 42. The No. 1 air pipe 41 and the No. 2 air pipe 42 The ends away from the air compressor 4 are connected with the mounting tube 52 through the connection, the No. 1 air pipe 41 and the No. 2 air pipe 42 and the mounting tube 52 are respectively located at the right rear and left rear of the wind wheel 57. When the No. 1 air pipe 41 discharges air, the wind wheel 57 is driven to rotate forward by the airflow, and when the No. 2 air pipe 42 discharges air, the wind wheel 57 is driven to rotate reversely by the airflow. An air outlet pipe 55 is installed through the mounting seat 2, and the connection position of the air outlet pipe 55 and the mounting seat 2 is located in front of the wind wheel 57, and the airflow is discharged through the air outlet pipe 55. The bottom of the wind wheel 57 is connected with a sun gear ring 58, and the inner wall of the mounting tube 52 is installed with an inner gear ring 59. The bottom of the inner gear ring 59 is rotatably connected with a driven ring 510, and three planetary gears 511 are rotatably installed on the driven ring 510. The sun gear ring 58 is located Inside the inner gear ring 59, the three planetary gears 511 are all meshed with the inner gear ring 59, and the three planetary gears 511 are all meshed with the sun gear ring 58. The sun gear ring 58, the inner gear ring 59 and the three planetary gears 511 form a planetary reduction gear set, which can reduce the rotation speed and increase the torque. When the wind wheel 57 rotates, it drives the sun gear ring 58 to rotate. When the three planetary gears 511 revolve, they drive the driven ring 510 to rotate. The bottom of the driven ring 510 is connected to two levers 512, and a sliding shaft 513 is installed on the lever 512. The driven ring 510 drives the two sliding shafts 513 to rotate through the two levers 512. The inner wall of the driven ring 510 is slidably connected to the optical axis 53. The outer wall of the optical axis 53 is provided with two sliding grooves 514, and the sliding groove 514 consists of a straight groove and a curved groove. The two slide grooves 514 are symmetrically arranged, and the two sliding shafts 513 are slidably connected with the two slide grooves 514 respectively. A drill bit 54 is installed at the bottom of the optical axis 53. When the two sliding shafts 513 start to rotate, the two sliding shafts 513 slide into the two curved grooves respectively through rotation and generate a downward reverse thrust on the two slide grooves 514. When the two sliding shafts 513 slide to the ends of the two curved grooves respectively, the two slide grooves 514 drive the optical axis 53 to move downward for a distance. At this time, the two sliding shafts 513 lock the optical axis 53 through the ends of the two curved grooves respectively and drive the optical axis 53 to rotate. The optical axis 53 drives the drill bit 54 to rotate. A rebound ring 56 is slidably installed on the inner wall of the mounting seat 2. The rebound ring 56 is located above the wind wheel 57. A spring is arranged between the rebound ring 56 and the wind wheel 57.The top of the optical axis 53 rests on the rebound ring 56, and the drill bit 54 disengages from the internal thread and gradually moves upward when the drill bit 54 rotates in the opposite direction. The curved grooves on the two slide grooves 514 also slide upward on the two slide shafts 513. When the drill bit 54 is disengaged from the nut, the elastic force of the spring on the rebound ring 56 causes the rebound ring 56 to drive the top of the optical axis 53 to reset upward, and the end of the air outlet pipe 55 away from the mounting seat 2 is aligned with the drill bit 54. The air outlet pipe 55 blows air to the processing position of the drill bit 54, which has an air cooling effect on the drill bit 54. When the internal thread processing is not performed, the staff can withdraw the optical axis 53 at any time. When the internal thread processing is performed, the two slide shafts 513 can automatically lock the optical axis 53 and drive the optical axis 53 to rotate, so that the staff can disassemble and replace the drill bit 54 by withdrawing the optical axis 53 at any time. The steps are relatively simple and do not delay the work progress. The staff can also set a plurality of spare optical axes 53 and drill bits 54 for easy replacement at any time. Long rods 516 are rotatably installed on the outer walls of both sides of the mounting seat 2, and short shafts 515 are connected to the outer walls of both sides of the sliding arm 51. Long grooves are opened on the long rods 516. The two short shafts 515 are slidably connected to the long grooves of the two long rods 516 respectively. A protective cover 517 is connected between the two long rods 516. When the sliding arm 51 moves downward, the two short shafts 515 drive the two long rods 516 to swing downward, so that the downward movement amplitude of the protective cover 517 is greater than the downward movement amplitude of the sliding arm 51. When the drill bit 54 contacts the nut, the protective cover 517 moves to the vicinity of the drill bit 54 to play a protective role, preventing flying debris from falling into the eyes of the staff and causing damage to the eyes of the staff. When the sliding arm 51 is reset upward, the protective cover 517 moves upward and resets, and does not block the vicinity of the drill bit 54.

[0022] For further information, see Fig. 9 - Fig.13The clamping assembly 6 is used to clamp the nut during processing. The clamping assembly 6 includes a material trough 61, which is installed on the operating table 1. The right end of the material trough 61 is connected to a slide 62. A storage box 7 is installed at the bottom of the operating table 1. The end of the slide 62 away from the material trough 61 is located above the storage box 7. The bottom of the sliding arm 51 is connected to a connecting block 63. The bottom of the connecting block 63 is connected to two inclined slot frames 64. A No. 1 slide 66 and a No. 2 slide 67 are installed on the operating table 1. The No. 1 slide 66 and the No. 2 slide 67 are respectively connected to clamping blocks 68. A roller 65 is installed through the No. 1 slide 66. The inclined slot frame 64 is provided with an inclined slot. The inclined slots of the two inclined slot frames 64 are respectively slidably connected to the outer surfaces of the two ends of the roller 65. When the two inclined slot frames 64 move downward, the roller 65 is pushed forward through the inclined slots. The first slide 66 and the second slide 67 are respectively connected with racks 69. A synchronous gear 610 is rotatably installed on the operating table 1 through a bracket. The two racks 69 are centrally symmetrically arranged with the synchronous gear 610 as the center. Both racks 69 are meshed with the synchronous gear 610. The two clamping blocks 68 are mirror-imaged. The first slide 66 and the second slide 67 respectively drive the two clamping blocks 68 to move toward each other through reverse motion, so that the two clamping blocks 68 clamp the nut and ensure that the nut is located directly below the drill bit 54 to avoid displacement during nut processing. At the same time, it also plays a centering positioning effect to avoid the internal thread processing from deviating from the center of the nut. A slider 612 is slidably installed on the operating table 1, and a connecting rod 611 is hinged on the slider 612. The end of the connecting rod 611 away from the slider 612 is hinged to the inclined slot frame 64 close to the slider 612. A barrel 615 is installed on the material trough 61. A mounting groove is provided on the material trough 61. A connecting rod 613 is slidably installed in the mounting groove of the material trough 61. One end of the connecting rod 613 is connected to the slider 612, and the other end of the connecting rod 613 is connected to a push block 614. The push block 614 has a certain elasticity. The push block 614 passes under the barrel 615 during the movement. When the push block 614 moves to the right, the material The nut at the bottom of the barrel 615 is pushed to the right, so that the next nut to be processed slides between the two clamping blocks 68. The processed nut is pushed onto the slide 62 and slides into the storage box 7 through the slide 62. After the push block 614 moves to the left, the nut in the barrel 615 falls, and the next nut falls on the material trough 61. The push block 614 can push this nut to the right when it moves to the right next time. The processed nuts fall into the storage box 7 in turn. The staff regularly transfers them, achieving the effect of automatic loading and unloading, further reducing the staff's operating steps, improving the level of automation, and improving work efficiency.

[0023] With the above structure, the working principle of this case is that in the standby state, the staff can directly pull out the optical axis 53, the staff can disassemble and replace the drill bit 54 on the optical axis 53, and can also prepare multiple optical axes 53. After the drill bits 54 are installed on multiple optical axes 53, they can be kept as spare; after starting the air compressor 4, the air compressor 4 can be controlled to exhaust air through the No. 1 air pipe 41 or the No. 2 air pipe 42. When the No. 1 air pipe 41 exhausts air, the No. 1 air pipe 41 blows air to the wind wheel 57 in the installation tube 52, and the wind wheel 57 is driven to rotate by the airflow, and the airflow is discharged through the air outlet pipe 55. When the wind wheel 57 rotates, it drives the sun gear ring 58 to rotate. The sun gear ring 58 drives the three planetary gears 511 to revolve while rotating by cooperating with the inner gear ring 59. The gear ring 58, the inner gear ring 59 and the three planetary gears 511 form a planetary reduction gear set, which can reduce the rotation speed and increase the torque. The three planetary gears 511 drive the driven ring 510 to rotate when they revolve, and the driven ring 510 drives the two sliding shafts 513 to rotate through the two levers 512. When the optical axis 53 is inserted and installed, the two sliding shafts 513 slide into the sliding grooves 514 along the straight grooves of the two sliding grooves 514 respectively. When the sliding shafts 513 contact the connection between the straight groove and the curved groove, the top of the optical axis 53 rests on the rebound ring 56. When the two sliding shafts 513 start to rotate, the two sliding shafts 513 slide into the two curved grooves respectively through rotation and generate downward reverse thrust on the two sliding grooves 514. When the two sliding shafts 513 slide to the ends of the two curved grooves respectively, the two sliding grooves 514 are 4 drives the optical axis 53 to move downward for a distance. At this time, the two sliding shafts 513 respectively lock the optical axis 53 through the ends of the two curved grooves and drive the optical axis 53 to rotate. The optical axis 53 drives the drill bit 54 to rotate, and the hydraulic cylinder 3 is started. The hydraulic cylinder 3 drives the installation cylinder 52 to move downward through the sliding arm 51. The installation cylinder 52 drives the optical axis 53 to move downward through the inner gear ring 59, the driven ring 510, the two levers 512 and the two sliding shafts 513. The drill bit 54 moves downward accordingly and processes the internal thread of the nut. At the same time, the air outlet pipe 55 blows air to the processing position of the drill bit 54, which has an air cooling effect on the drill bit 54. When the internal thread processing of the nut is completed, the hydraulic cylinder 3 is controlled to retract, so that the sliding arm 51 is reset upward. The retraction speed of the hydraulic cylinder 3 is slower than the extension speed. The first air pipe 41 is closed and the second air pipe 42 is started. When the second air pipe 42 blows out air, the airflow drives the wind wheel 57 to rotate in the opposite direction. Based on the above principle, the two sliding shafts 513 start to rotate in the opposite direction. Since the internal thread of the nut has a certain friction force on the drill bit 54, the two sliding shafts 513 respectively press against the curved grooves of the two slide grooves 514 when rotating in the opposite direction and drive the optical axis 53 to rotate in the opposite direction, so that the drill bit 54 gradually disengages from the internal thread of the nut when rotating in the opposite direction. At the same time, the drill bit 54 gradually moves upward as it disengages from the internal thread. The curved grooves on the two slide grooves 514 also slide upward on the two sliding shafts 513. When the drill bit 54 disengages from the nut, the elastic force of the spring on the rebound ring 56 causes the rebound ring 56 to drive the top of the optical axis 53 to reset upward. At the same time,The two sliding shafts 513 slide into the connection between the curved groove and the straight groove on the two sliding grooves 514 again by rotating in the opposite direction, so that the staff can pull out the optical shaft 53 at any time when the internal thread processing is not performed. When the internal thread processing is performed, the two sliding shafts 513 can automatically lock the optical shaft 53 and drive the optical shaft 53 to rotate, so that the staff can disassemble and replace the drill bit 54 by pulling out the optical shaft 53 at any time. The steps are relatively simple and do not delay the work progress. The staff can also set up multiple spare optical shafts 53 and drill bits 54 for easy replacement at any time; when the sliding arm 51 moves downward, the two short shafts 515 drive the two long rods 516 to swing downward, so that the downward movement of the protective cover 517 is greater than the downward movement of the sliding arm 51. When the drill bit 54 contacts the nut, the protective cover 517 moves to the vicinity of the drill bit 54 to play a protective role. When the sliding arm 51 After resetting upward, the protective cover 517 moves upward to reset, and does not block the area around the drill bit 54; through the setting of the thread processing assembly 5, the two sliding shafts 513 cooperate with the optical axis 53, so that when the internal thread processing is not performed, the staff can pull out the optical axis 53 at any time. When the internal thread processing is performed, the two sliding shafts 513 can automatically lock the optical axis 53 and drive the optical axis 53 to rotate, so that the staff can remove and replace the drill bit 54 at any time by pulling out the optical axis 53. The steps are relatively simple and do not delay the work progress. The staff can also set up multiple spare optical axes 53 and drill bits 54 for easy replacement at any time; through the setting of the protective cover 517, when the drill bit 54 contacts the nut, the protective cover 517 can be moved around the drill bit 54 for protection to prevent splashing debris from falling into the eyes of the staff and causing damage to the eyes of the staff.

[0024] The staff puts the nuts to be processed into the barrel 615 in advance, and the nuts are stacked vertically in the barrel 615. The nuts at the bottom 615 of the barrel fall on the trough 61. The staff puts the first nut to be processed between the two clamping blocks 68. When the sliding arm 51 moves downward, it drives the two inclined slot frames 64 to move downward through the connecting block 63. The two inclined slot frames 64 push the roller 65 forward through the inclined slot. When the roller 65 moves forward, it drives the No. 1 slide 66 and the rack 69 above it to move forward. The rack 69 of the No. 1 slide 66 drives the rack 69 of the No. 2 slide 67 to move backward through the synchronous gear 610, so that the No. 2 slide 67 moves backward. The No. 1 slide 66 and the No. 2 slide 67 respectively drive the two clamping blocks 68 to approach through reverse motion. The two clamping blocks 68 move in directions close to each other, so that the two clamping blocks 68 clamp the nut and ensure that the nut is directly under the drill bit 54. After the processing is completed, the sliding arm 51 resets upward, and the two inclined slot frames 64 drive the No. 1 slide 66 to reset backward through the roller 65, and the No. 2 slide 67 resets forward accordingly, and the two clamping blocks 68 disengage from the nut, achieving the effect of automatically clamping the nut during processing, reducing the steps of manual operation of the clamping device by the staff, and improving work efficiency; when the two inclined slot frames 64 move upward, the inclined slot frame 64 connected to the connecting rod 611 drives the slider 612 to move right through the connecting rod 611, and the slider 612 drives the push block 614 to move right through the connecting rod 613, and when the push block 614 moves to the right, it pushes the nut at the bottom of the barrel 615 to the right , so that the next nut to be processed slides between the two clamping blocks 68, and the processed nut is pushed onto the slideway 62 and slides into the storage box 7 through the slideway 62. The push block 614 has a certain elasticity. When the two clamping blocks 68 have not completely loosened the nut, the push block 614 can be deformed without affecting its movement to the right. After the two clamping blocks 68 have completely loosened the nut, the push block 614 restores its shape. When the chute frame 64 moves downward, the chute frame 64 drives the slider 612 to move to the left through the connecting rod 611, and the push block 614 moves to the left accordingly, so that the push block 614 is temporarily not under the barrel 615, and the nut in the barrel 615 falls, and the next nut falls on the trough 61. The push block 614 can push this nut to the right when it moves to the right next time, and the processed The nuts fall into the storage box 7 in turn, and the staff transfers them regularly, achieving the effect of automatic loading and unloading, further reducing the staff's operating steps; through the setting of the clamping assembly 6, the two clamping blocks 68 can clamp the nut when the nut is about to be processed, avoiding displacement during nut processing, and also playing a centering positioning effect, avoiding the internal thread processing from deviating from the center of the nut; through the cooperation of the material trough 61, the push block 614 and the slide 62, after one nut is processed, the push block 614 can push the next nut to the processing position, and push the processed nut into the slide 62 and slide it into the storage box 7, achieving the effect of automatic loading and unloading, further simplifying the staff's operation, improving the level of automation, and improving work efficiency.
