Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a bolt screwing device. Background Technique

[0002] Among various components of power facilities, bolts or screws are commonly used fasteners and are very widely used. When power equipment needs to be maintained, disassembly or fastening is often required, and in most cases, a screwdriver is used. Most of the grooves on nuts are regular polygons, one-word or cross-shaped structures. During the process of using a screwdriver to disassemble / fasten bolts or screws, the situation of slipping often occurs, damaging the nuts, and there are still some defects in existing devices; for example;

[0003] For example, an automatic bolt screwing device with a publication number of CN215318369U. When it is used, the open end of the cover body is directed towards the bolt head to be screwed, and the cover body is pressed downwards so that the movable column is in contact with the top surface of the bolt head at the end surface of the open end of the cover body. Under the action of the downward pressure, the movable column in contact with the top surface of the bolt head is pressed upwards, and the movable column not in contact with the top surface of the bolt head remains in place. Thus, a limiting space roughly matching the shape of the bolt head is formed among the movable columns that have not risen around the bolt head. Thus, when a pistol drill screws the cover body through a connecting rod, the movable columns that have not risen around the bolt head come into contact interference with the side wall of the bolt head, thereby completing the screwing of the bolt head;

[0004] The above device has some problems. It is not convenient to disassemble and assemble during use. Only the cover body is set to be pressed downwards, and the pressing effect is not good, and the degree of automation is relatively low.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Please refer to Figures 1-6 , the present utility model provides a technical solution: a bolt screwing device, including a machine body 1 and a switch 2, and a handle is provided on the machine body 1;

[0027] Inside the body 1, there is a motor 3 installed. The motor 3 is connected to the first gear 4, and the first gear 4 meshes with the second gear 5. The second gear 5 is connected to the rotating shaft 6. The rotating shaft 6 is connected to the body 1 through bearings, and there are multiple bearings, and the bearings are symmetrically arranged about the center of the rotating shaft 6. The rotating shaft 6 and the connecting block 7 are connected through a clamping connection structure. The clamping connection structure includes: there is a groove inside the connecting block 7, and a push rod 9 is arranged in the groove. The push rod 9 is connected to the stop block 10, and the stop block 10 is clamped with the clamping block 11. The clamping block 11 is connected to the rotating shaft 6. On both sides of the rotating shaft 6 and the connecting block 7, there are double-headed bolts 8, and the double-headed bolts 8 are symmetrically arranged about the center of the rotating shaft 6. Above both ends of the double-headed bolts 8, there are nuts, and the material of the double-headed bolts 8 is metal. First, hold the handle and move the body 1 to the designated position. Then, the rotating head 19 and the moving plate 18 can be separated by screwing the first bolt 21. Different types of rotating heads 19 can be replaced by screwing the bolts according to the on-site needs. At this time, press the clamping block 11 protruding below the rotating shaft 6 against the surface slot of the upper connecting block 7. At this time, the push rod 9 inside the connecting block 7 drives the stop block 10 to move forward, so that the stop block 10 and the clamping block 11 are clamped to complete the installation between the rotating shaft 6 and the connecting block 7. At this time, take out the double-headed bolts 8, use the double-headed bolts 8 to fix both sides of the connecting block 7 and the rotating shaft 6 respectively, and then screw the nuts to make the fixation more stable;

[0028] The connecting block 7 is connected to the fixed block 14 through a buffer structure. The buffer structure includes: there is a slider 12 inside the connecting block 7, and a spring 13 is arranged on the surface of the slider 12. The front end of the slider 12 is connected to the fixed block 14. The slider 12 is arranged in the chute inside the connecting block 7. On both sides behind the slider 12, there are also gaskets, and the material of the gaskets is rubber. Inside the fixed block 14, there is a third gear 15, and the third gear 15 meshes with the rack 16. The rack 16 is arranged on the slide rod 17. The front end of the rack 16 is provided with a moving plate 18, and the moving plate 18 is connected to the rotating head 19 through the first bolt 21. There is a fixed frame 20 on the rotating head 19, and there is a groove inside the rotating head 19;

[0029] During use, align the groove in the lower rotating head 19 with the bolt to be screwed. After the bolt is fixed above and the groove inside the rotating head 19, start the motor 3 through the switch 2 to drive the first gear 4 to rotate. Since the first gear 4 meshes with the second gear 5, the second gear 5 drives the rotating shaft 6 to rotate inside the machine body 1 through the bearing, and at the same time drives the lower connecting block 7 to rotate, causing the bolt to rotate. At this time, the bolt slowly enters the outside. At the same time, start the third gear 15 to rotate through the switch 2. Since the third gear 15 meshes with the rack 16, the rack 16 moves on the slide bar 17 and drives the lower rotating head 19 to move along with the entry of the bolt. When in use, there is no need to move the machine body 1, and it can also be applied to different environments. When the installation position of the bolt is relatively deep, this structure can be used to screw the bolt at a deeper position. At the same time, when screwing the bolt, the fixed block 14 drives the slider 12 to move in the chute inside the connecting block 7 through the spring 13, so as to buffer the lower rotating head 19 and prevent the rotating head 19 of the bolt from being damaged due to excessive pressure. At the same time, the fixed frame 20 above the rotating head 19 makes the rotating head 19 itself more robust.

[0030] Working principle: When using the bolt screwing device, first hold the handle and move the body 1 to the designated position. Then, the rotating head 19 and the moving plate 18 can be separated by turning the first bolt 21. Different types of rotating heads 19 can be replaced according to the bolts to be screwed on-site. At this time, press the block 11 protruding below the rotating shaft 6 against the card slot on the surface of the upper connecting block 7. At this time, the push rod 9 inside the connecting block 7 drives the stop block 10 to move forward, so that the stop block 10 and the card block 11 are engaged to complete the installation between the rotating shaft 6 and the connecting block 7. At this time, take out the double-headed bolt 8, fix the two sides of the connecting block 7 and the rotating shaft 6 with the double-headed bolt 8 respectively, and then turn the nut to make the fixation more stable. When in use, align the groove in the lower rotating head 19 with the bolt to be screwed. After the bolt is fixed with the groove inside the rotating head 19 above, at this time, start the motor 3 through the switch 2 to drive the first gear 4 to rotate. Since the first gear 4 is engaged with the second gear 5, the second gear 5 drives the rotating shaft 6 to rotate inside the body 1 through the bearing, and at the same time drives the lower connecting block 7 to rotate, so that the bolt rotates. At this time, the bolt slowly enters the outside. At the same time, start the third gear 15 to rotate through the switch 2. Since the third gear 15 is engaged with the rack 16, the rack 16 moves on the slide bar 17 and drives the lower rotating head 19 to move along with the entry of the bolt. When in use, there is no need to move the body 1, and it can also be applicable to different environments. When the installation position of the bolt is relatively deep, the bolt at a deeper position can be screwed through this structure. At the same time, when screwing the bolt, the fixing block 14 drives the slider 12 to move in the chute inside the connecting block 7 through the spring 13, so as to buffer the lower rotating head 19 and prevent the bolt rotating head 19 from being damaged due to excessive pressure. At the same time, the fixing frame 20 above the rotating head 19 makes the rotating head 19 itself more robust.
