DETAILED DESCRIPTION

[0025] The following will be combined with the attached embodiment of the present utility model Figure 1-5 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0026] A wingspan bolt thread grinding machine comprises a frame 1, a rotating shaft 2 is penetrated on one side of the frame 1, a swing arm 3 is fixedly installed on one end of the rotating shaft 2, a lower pressure roller 4 is rotatably installed on the end of the swing arm 3 away from the rotating shaft 2, and a swing arm 2 5 is fixedly installed on the other end of the rotating shaft 2. A hydraulic cylinder 17 is movably installed on one side of the frame 1, and the output end of the hydraulic cylinder 17 is movably installed on the swing arm 2 5. Two stepping motors 6 are fixedly installed on one side of the frame 1, and the output shaft of the stepping motor 6 penetrates to the outside of the frame 1 and is fixedly installed with a grinding roller 7, and the two grinding rollers 7 are both compatible with the lower pressure roller 4. An adjusting cavity 9 is opened on one side of the frame 1, and a supporting assembly 8 compatible with the swing arm 3 is movably arranged inside the adjusting cavity 9.

[0027] The specific usage process is as follows: when working, turn on the machine, and then start the hydraulic cylinder 17. The hydraulic cylinder 17 will push the swing arm 2 5 to rotate upward with the rotating shaft 2 as the rotating axis. At the same time, the hydraulic cylinder 17 will also make corresponding activities to ensure the smooth progress of the work. When the swing arm 2 5 rotates, it will drive the rotating shaft 2 to rotate, and the rotating shaft 2 will drive the swing arm 1 3 to rotate upward. The swing arm 1 3 will drive the lower pressure roller 4 to rotate upward. After the lower pressure roller 4 moves upward, the spacing between the lower pressure roller 4 and the two grinding rollers 7 is expanded. At this time, the user places the bolts to be processed on the two grinding rollers 7, and then controls the swing arm 2 5 to rotate downward through the hydraulic cylinder 17. The swing arm 2 5 drives the rotating shaft 2 to rotate, and the rotating shaft 2 will drive the swing arm 1 3 to rotate downward. Finally, the lower pressure roller 4 will also follow The swing arm 3 moves downward until the lower pressure roller 4 presses on the bolt workpiece, and then the two stepper motors 6 are started, and the stepper motor 6 will drive the grinding roller 7 to rotate. It should be noted that the two grinding rollers 7 rotate in opposite directions, and the workpiece will also rotate along with the drive of the two grinding rollers 7, and the lower pressure roller 4 will press the workpiece tightly, and will also make corresponding activities on the basis of ensuring normal grinding work to ensure the normal grinding of the workpiece thread. It should be noted that before this, the height of the supporting assembly 8 must be adjusted first, because the supporting assembly 8 will provide a supporting effect on the swing arm 3, ensuring that the swing arm 3 can stay stably in the current position, reducing the working pressure of the swing arm 2 5, and extending the service life of the swing arm 2 5. When the supporting assembly 8 is adjusted, the shell 81 is in the adjustment position. The width of the inner part of the cavity 9 can be flexibly adjusted according to actual needs to meet work needs, and at the same time, the stability of the adjustment cavity 9 after adjustment can be ensured, which provides convenience for the user's work. When adjusting, the shell 81 is manually operated to move, squeeze the movable shell 82 and make the movable shell 82 shrink into the movable cavity 84, and compress the spring 83 at the same time, so that the entire supporting assembly 8 can be flexibly adjusted and moved in the adjustment cavity 9. After the adjustment is completed, the shell 81 is released. Under the action of the spring 83, the movable shell 82 is ejected from the inner cavity of the movable cavity 84, so that the entire supporting assembly 8 can be fixed in a suitable position to ensure the normal operation of the grinder. That is to say, after the movable shell 82 is unfolded, a part of the supporting assembly 8 will be stuck in the corresponding "step" on the inner side of the adjustment cavity 9. The support assembly 8 is positioned on the "ladder" to realize the positioning of the support assembly 8, and when the movable shell 82 is retracted into the outer shell 81, the part of the support assembly 8 located in the adjustment chamber 9 can move away from the "step" horizontally, so that it can be moved up and down for adjustment. After the adjustment, it can be stuck on the corresponding "step" again. The position of the support assembly 8 after positioning is the position where the swing arm 3 is suspended. During this process, the user can debug according to the actual size of the workpiece. Then, according to the different sizes of the workpieces, this method can also be used for adjustment to meet the actual work needs, and the spacing between the two grinding rollers 7 can also be adjusted according to the actual work needs. When adjusting, first pull out the two positioning pins 15, and then rotate the adjusting screw 11. The adjusting screw 11 drives the threaded sleeve 12 to move in the slide groove 10.The threaded sleeve 12 will drive the slider 13 to slide in the gap, and the two positioning plates 14 will also move with the slider 13. When the distance between the two grinding rollers 7 meets the working requirements, stop rotating the adjusting screw 11, and then insert the positioning pin 15 back into the positioning plate 14, and the positioning pin 15 is also inserted back into the corresponding positioning hole 16 to achieve the positioning of the slider 13, and also achieve the positioning of the stepper motor 6 and the grinding roller 7 after the position adjustment, to ensure the stability of the stepper motor 6 and the grinding roller 7 during operation, to meet the processing requirements of the workpiece, to provide convenience for the user's work, and the lower pressure roller 4 is an upwardly unfolded working mode, compared with the traditional grinding machine structure, it has higher flexibility and more space for users to operate, to meet the processing requirements of workpieces of different sizes.

In this way, when adjusting and moving, the notch can limit the slider 13, ensure the stability of the slider 13, the stepper motor 6 and the grinding roller 7 during adjustment and movement, and provide convenience for the user's work.

[0031] A slide groove 10 is provided at the bottom of the inner cavity of the notch, and a threaded sleeve 12 is slidably installed inside the slide groove 10. The top of the threaded sleeve 12 is fixedly connected to the slider 13. An adjusting screw 11 is rotatably installed in the inner cavity of the slide groove 10.
