DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-Figure 4 As shown, the embodiment of the utility model proposes a precision machining device for high-lock nuts for aerospace, including: a body 1, a fixing plate 2 is fixedly connected to the surface of the body 1, a fixing assembly, the fixing assembly includes a bidirectional threaded rod 3 that is rotatably connected to the side wall of the fixing plate 2 through a bearing, a limiting slide groove 4 is provided on the surface of the body 1, and a fixing nut 5 is threadedly connected on the threaded sections of the bidirectional threaded rod 3 with opposite thread directions, and the bottom surfaces of the two fixing nuts 5 are fixedly connected to the limiting sliders 6, and the two limiting sliders 6 slide in the limiting slide grooves 4 respectively, and the side walls of the two fixing nuts 5 are fixedly connected to a No. 1 connecting rod 7, and the opposite side ends of the two No. 1 connecting rods 7 are fixedly connected to a clamping plate 8, and the two clamping plates 8 cooperate with each other, and the assembled figure is a regular hexagon, which is used to conform to the shape of most nuts 1. Through the clamping plate 8 of such a shape, the clamping is more stable, and the side end of the bidirectional threaded rod 3 is fixedly connected to a knob, and the surface of the knob is provided with an anti-slip texture, which is convenient for the staff to operate;

[0025] When using, when high-precision machining of locking nuts is required, first fix the workpiece to be processed through the fixing component, and turn the two-way threaded rod 3 by the knob. When the two-way threaded rod 3 rotates, the two fixing nuts 5 are limited by the limiting slide groove 4 and the two limiting slide blocks 6, so that they will not rotate with the two-way threaded rod 3, and then move left and right along the two-way threaded rod 3 under the meshing action between the threads, and the two fixing nuts 5 will move towards each other. When the two fixing nuts 5 move similarly, the two No. 1 connecting rods 7 will drive the two clamps 8 to gradually approach, and then clamp and fix the workpiece to be processed between the two. After the fixation is completed, the nut processing is carried out through the machine body 1. Through the set fixing component, the workpiece to be processed can be conveniently and stably fixed, so that the workpiece has good stability during the processing, which is conducive to high-precision processing and improves the processing efficiency.

[0026] Two cleaning mechanisms, both cleaning mechanisms include a transmission assembly and a cleaning assembly, the transmission assembly includes a driving bevel gear 9 circumferentially fixedly connected to the bidirectional threaded rod 3, a mounting plate 10 is fixedly connected to the side wall of the body 1, the surface of the mounting plate 10 is rotatably connected to a first rotating shaft 11 and a second rotating shaft 12 through a bearing, the top of the first rotating shaft 11 is fixedly connected to a driven bevel gear 13, the driving bevel gear 9 is meshed with the driven bevel gear 13, the first rotating shaft 11 is circumferentially fixedly connected to a driving wheel 14, the second rotating shaft 12 is circumferentially fixedly connected to a driven wheel 15, the main The driving wheel 14 is connected to the driven wheel 15 through a belt transmission. The cleaning assembly includes an incomplete gear 16 fixedly connected to the top of the second rotating shaft 12. A complete gear 17 is rotatably provided on the surface of the body 1. The incomplete gear 16 is meshed with the complete gear 17. A sleeve 18 is fixedly connected to the surface of the body 1. A spring 19 is fixedly connected between the complete gear 17 and the sleeve 18. A second connecting rod 20 is fixedly connected to the surface of the complete gear 17. A cleaning rod 21 is fixedly connected to the side end of the second connecting rod 20. The two cleaning mechanisms are symmetrically arranged about the fixed plate 2.

[0027] After the processing is completed, the clamping of the workpiece needs to be released, and the two-way threaded rod 3 is rotated in the opposite direction. The rotation of the two-way threaded rod 3 will drive the driving bevel gear 9 to rotate, and then through the meshing transmission, the driven bevel gear 13 and the No. 1 rotating shaft 11 are driven to rotate, and the No. 1 rotating shaft 11 is driven to rotate the driving wheel 14, and through the belt transmission, the driven wheel 15 and the No. 2 rotating shaft 12 are driven to rotate, and then the incomplete gear 16 is driven to rotate. The meshing between the incomplete gear 16 and the complete gear 17 will drive the complete gear 17 to rotate, and will drive the spring spring 19 to twist. When the incomplete gear 16 rotates to a smooth arc surface, The complete gear 17 loses its meshing function and rotates under the action of the clockwork spring 19. Then, when the incomplete gear 16 rotates one circle, the complete gear 17 will perform a period of reciprocating rotation. Therefore, the complete gear 17 will drive the cleaning rod 21 to perform periodic reciprocating swings, which can sweep away the metal debris on the surface of the body 1. The cleaning mechanism will work when the workpiece is fixed and the clamp is released. Through the set cleaning mechanism, the metal debris on the surface of the body can be removed when the workpiece is fixed and the clamp is released, thereby reducing the possibility of the surface of the processed product being contaminated with metal debris, thereby improving the quality of the finished product.

[0028] The detailed working process of the utility model is as follows:

[0029] When the two locking nuts are in close contact, the two clamping plates 8 are driven by the two No. 1 connecting rods 7 to gradually approach each other, and the workpiece to be processed between the two clamping plates 8 is clamped and fixed. After the fixation is completed, the nut processing is carried out through the machine body 1. By means of the set fixing assembly, the workpiece to be processed can be conveniently and stably fixed, so that the workpiece has good stability during the processing, which is beneficial to high-precision processing and improves the processing efficiency.

[0030] After the processing is completed, the clamping of the workpiece needs to be released, and the two-way threaded rod 3 is rotated in the opposite direction. The rotation of the two-way threaded rod 3 will drive the driving bevel gear 9 to rotate, and then through the meshing transmission, the driven bevel gear 13 and the No. 1 rotating shaft 11 are driven to rotate, and the No. 1 rotating shaft 11 is driven to rotate the driving wheel 14, and through the belt transmission, the driven wheel 15 and the No. 2 rotating shaft 12 are driven to rotate, and then the incomplete gear 16 is driven to rotate. The meshing between the incomplete gear 16 and the complete gear 17 will drive the complete gear 17 to rotate, and will drive the spring spring 19 to twist. When the incomplete gear 16 rotates to a smooth arc surface, The complete gear 17 loses its meshing function and rotates under the action of the clockwork spring 19. Then, when the incomplete gear 16 rotates one circle, the complete gear 17 will perform a period of reciprocating rotation. Therefore, the complete gear 17 will drive the cleaning rod 21 to perform periodic reciprocating swings, which can sweep away the metal debris on the surface of the body 1. The cleaning mechanism will work when the workpiece is fixed and the clamp is released. Through the set cleaning mechanism, the metal debris on the surface of the body can be removed when the workpiece is fixed and the clamp is released, thereby reducing the possibility of the surface of the processed product being contaminated with metal debris, thereby improving the quality of the finished product.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
