Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of machining tools, in particular to a screwing wrench with a bolt clamping structure. BACKGROUND

[0002] The wrench is generally composed of a handle, a connecting rod and a screwing head. The screwing head is connected to one end of the connecting rod, and the other end of the connecting rod is connected to the handle. A rubber layer is installed on the outside of the handle to protect the user's hands. When in use, the screwing head is connected to the groove on the top of the bolt, and the handle is rotated to exert force on the bolt through the screwing to loosen and remove the bolt. However, when the existing wrench exerts force on the bolt, the upper slot of the bolt is shallow, and the screwing head may slide out from one side when rotating. At this time, the bolt needs to be continuously adjusted to be removed. The bolt is not clamped during the removal process, which may easily fall off and is not easy to find, affecting the secondary use. SUMMARY

[0003] In view of the above, the present application provides a screwing wrench with a bolt clamping structure, which clamps the bolt when screwing the bolt to prevent the bolt from falling off.

[0011] Preferably, the screw head further includes a first mounting post connected to the second end of the connecting post. The first end of the first mounting post has an internal thread, and the second end of the connecting post is screwed into the first end of the first mounting post.

[0018] The beneficial effects of this invention are as follows: A screw-tightening wrench with a bolt clamping structure uses a drive motor to move at both the first and second ends of the wrench body to clamp and tighten bolts. When the first drive shaft of the drive motor is connected to the movable plate via a first locking assembly, the rotation of the first drive shaft drives the movable plate to move relative to the fixed plate, thereby clamping the bolt together with the fixed plate. Tightening the wrench body then tightens the bolt. When the second drive shaft of the drive motor is connected to the tightening head via a second locking assembly, and the tightening seat on the tightening head is aligned with and connected to the bolt head, the rotation of the second drive shaft drives the tightening head to rotate automatically tighten the bolt. When the tightening seat aligns with the bolt head, the suction cup moves to the junction of the two, creating a vacuum and achieving flexible clamping of the bolt to prevent it from falling off during tightening. This screw-tightening wrench with a bolt clamping structure can clamp various types of bolts and prevent them from falling off, thanks to the dual-drive mechanism of the drive motor.

Detailed Implementation

[0028] To facilitate understanding of the present invention, the following description is provided in conjunction with the accompanying drawings and embodiments.

[0029] Please see Figures 1 to 6 This invention provides a screw-on wrench with a bolt clamping structure, comprising a wrench body, a clamping assembly, a screw-on assembly, and a drive motor 10. Wherein:

[0030] like Figure 1 As shown, the wrench body has a hollow interior forming a first accommodating space. Specifically, the wrench body includes a fixed tube 8 and a rotating tube 9, forming the first accommodating space within the two tubes.

[0031] A clamping assembly for clamping bolts includes a fixed plate 123 and a movable plate 121. The fixed plate 123 is fixed to a first end of the wrench body, and the movable plate 121 is movably mounted on the first end of the wrench body relative to the fixed plate 123. A space for clamping bolts is formed between the movable plate 121 and the fixed plate 123, and the movement of the movable plate 121 can achieve clamping and fixing of the bolts.

[0032] A screw-tightening assembly for tightening bolts is located at the second end of the wrench body. It includes a screw-tightening head for connecting the bolt and a suction cup 2 coaxially sleeved on the outside of the screw-tightening head. The opening of the suction cup faces away from the first end of the wrench body. The suction cup 2 is equipped with a vacuum-evacuating device 3 for evacuating the suction cup 2. Preferably, the screw-tightening head includes a first mounting post 1, a connecting post 111, and a screw-tightening seat 112.

[0033] The drive motor 10 is installed in the first accommodating space and moves between the first end and the second end of the wrench body. The drive motor 10 includes a coaxial first drive shaft and a second drive shaft. The end of the first drive shaft away from the drive motor 10 is selectively connected to the movable plate 121 through the first locking component 11. The end of the second drive shaft away from the drive motor 10 is selectively connected to the screw head through the second locking component 7. The connection between the first drive shaft and the movable plate 121 and the connection between the second drive shaft and the screw head are selective.

[0034] Specifically, a first docking rod 101 is connected to the first drive shaft of the drive motor 10, and the first docking rod 101 is connected to the first locking assembly 11. A second docking rod 102 is connected to the second drive shaft of the drive motor 10, and the second docking rod 102 is connected to the second locking assembly 7. When the first drive shaft is connected to the movable plate 121 via the first locking assembly 11, the second drive shaft is not connected to the screw head via the second locking assembly 7. Similarly, when the second drive shaft is connected to the screw head, the first drive shaft is not connected to the movable plate 121.

[0035] When the drive motor 10 moves to the first end of the wrench body, the first drive shaft is connected to the movable plate 121. The first drive shaft can drive the movable plate 121 to move relative to the fixed plate 123. Therefore, moving the movable plate 121 can make the movable plate 121 and the fixed plate 123 work together to clamp the bolt.

[0036] When the drive motor 10 moves to the second end of the wrench body, the second drive shaft connects to the screw-on head. The screw-on seat 112 on the screw-on head connects to the bolt head. The second drive shaft drives the screw-on head to rotate, causing the screw-on seat 112 to unscrew the bolt. When the screw-on seat 112 connects to the bolt head, the suction cup 2 is moved to the connection point, and a vacuum device 3 is used to evacuate the suction cup 2, thus creating a flexible clamp on the bolt to prevent it from falling off during screw-on. After the bolt is unscrewed, it remains attached to the suction cup 2. The wrench body is then moved to the top of the toolbox, the vacuum device 3 is turned off, and the operator grasps the bolt and applies downward force. The bolt then falls from the screw-on seat 112 into the toolbox for collection.

[0037] As a preferred implementation method, such as Figure 1As shown, the screw-on head includes a connecting post 111 with external threads and a screw-on seat 112 connected to the first end of the connecting post 111. A threaded sleeve 21 with internal threads is connected to the side of the suction cup 2 away from the opening, and the threaded sleeve 21 is screwed onto the connecting post 111. The shape of the screw-on seat 112 matches the groove on the top of the bolt head of the screw being screwed on, such as... Figure 2 As shown, the shape of the screw seat 112 can be either cross-shaped or slotted. By rotating the threaded sleeve 21, the suction cup 2 can be moved up and down on the connecting post 111, thereby moving the suction cup 2 to the point of contact when the screw seat 112 abuts against the bolt head.

[0038] As a preferred implementation method, such as Figure 2 As shown, a magnet 4 is installed inside the screw-on base 1, which can strengthen the flexible clamping between the wrench body and the bolt, making it less likely for the wrench to slip out of the hole during use.

[0039] As a preferred implementation method, such as Figure 1 As shown, the screw head 1 also includes a first mounting post 1 connected to the second end of the connecting post 111. The first end of the first mounting post 1 has an internal thread. The second end of the connecting post 111 is screwed into the first end of the first mounting post 1. The hollow interiors of the connecting post 111 and the first mounting post 1 respectively form a second accommodating space and a third accommodating space. The vacuum pump 3 includes a vacuum pump 31 and a suction pipe 32 connected to one end of the vacuum pump 31. The vacuum pump 31 is installed in the third accommodating space, and the suction pipe 32 is installed in the second accommodating space. The connecting post 111 has a suction hole 33 that connects the suction pipe 32 and the suction cup 2.

[0040] Specifically, a vacuum pump 31 is installed inside the first mounting post 1, and a suction pipe 32 is installed inside the connecting post 111. When the suction cup 2 moves to the connection between the bolt and the screw seat 112, the vacuum pump 31 is activated. The vacuum pump 31 draws out the air inside the suction cup 2 through the suction pipe 32 and the air extraction hole 33, creating a vacuum space between the suction cup 2 and the bolt, thus achieving flexible clamping of the bolt. Preferably, air extraction holes 33 are equidistantly provided at the bottom of the connecting post 111.

[0041] As a preferred implementation method, such as Figure 4 and Figure 5As shown, a first elastic limiting member 5 is symmetrically installed at the connection between the first mounting post 1 and the connecting post 111. The first elastic limiting member 5 includes a first limiting post 51 and a first spring 54 connecting the first limiting post 51 and the first mounting post 1. A first mounting hole is correspondingly opened on the connecting post 111, and the other end of the first limiting post 51 is inserted into the first mounting hole. A pull rod 53 is provided on the first limiting post 51 for pulling the first limiting post 51 to move away from the connecting post 111. Preferably, a connecting rod 52 is provided at the end of the first limiting post 51 away from the connecting post 111. The connecting rod 52 is sleeved inside the first spring 54 and passes through the first mounting post 1 to connect with the pull rod 53.

[0042] Specifically, the first spring 54 is installed between the first mounting post 1 and the first limiting post 51, and the first limiting post 51 is inserted into the connecting post 111, which serves to limit and fix the connection between the first mounting post 1 and the connecting post 111. When the pull rod 53 is pulled away from the connecting post 111, the pull rod 53 drives the first limiting post 51 to move outward through the connecting rod 52 until it separates from the first mounting hole on the connecting post 111. At this time, the first mounting post 1 and the connecting post 111 can be separated by rotating them relative to each other.

[0043] Since the suction cup 2 is severely worn after long-term use and needs to be replaced, after removing the first elastic limiting member 5 from the first mounting post 1 and the connecting post 111, screw the first mounting post 1 and the connecting post 111 to separate the first mounting post 1 and the connecting post 111. At this time, rotate the threaded sleeve 21 to move it away from the screwing seat 112 to remove the suction cup 2 for replacement.

[0044] In a preferred embodiment, the second end of the first mounting post 1 is connected to the second locking component 7. The second end of the first mounting post 1 has an internal thread, and the first end of the second locking component 7 has an internal thread. The first end of the second locking component 7 is screwed into the second end of the first mounting post 1.

[0045] As a preferred implementation method, such as Figure 5 As shown, a second elastic limiting member 6 is symmetrically installed at the connection between the second locking component 7 and the first mounting post 1. The second elastic limiting member 6 includes a second limiting post 62 and a second spring 61 connected between the second limiting post 62 and the second locking component 7. A second mounting hole is correspondingly opened on the first mounting post 1, and the other end of the second limiting post 62 is inserted into the second mounting hole.

[0046] Specifically, a second spring 61 connects the second limiting post 62 and the second locking assembly 7, and one end of the second limiting post 62 is inserted into the first mounting post 1, which limits and fixes the connection between the first mounting post 1 and the second locking assembly 7. When the second limiting post 62 is pressed, it moves away from the first mounting post 1 and compresses the second spring 61 until it is completely disengaged from the second mounting hole. The second elastic limiting member 6 then cancels its limiting and fixing effect on the first mounting post 1 and the second locking assembly 7. At this point, the first mounting post 1 and the second locking assembly 7 can be separated by twisting them.

[0047] When performing maintenance on the vacuum pump 31 later, press the second limiting post 62 to cancel the limiting and fixing effect of the second elastic limiting member 6 on the first mounting post 1 and the second locking component 7, and twist the first mounting post 1 and the second locking component 7 to separate the first mounting post 1 and the second locking component 7. Then, invert the vacuum pump 31 to remove it.

[0048] As a preferred implementation method, such as Figure 1 As shown, the second end of the second locking component 7 is rotatably connected to the second end of the wrench body. The top surface of the second end of the second locking component 7 is connected to the second drive shaft of the drive motor 10. The second end of the second locking component 7 is provided with a limiting plate, and the second end of the wrench body is correspondingly provided with a first limiting hole, in which the limiting plate is inserted. The second drive shaft of the drive motor 10 is connected to a second docking rod 102. The top surface of the second end of the second locking component 7 forms a second limiting hole for the second docking rod 102 to be inserted, in which the second docking rod 102 is inserted. Preferably, a PLC control board 13 for controlling the rotation of the drive motor 10 is installed inside the wrench body, and an instruction button 14 connected to the PLC control board 13 is provided outside the wrench body.

[0049] Specifically, the drive motor 10 is moved to the second end of the wrench body, and the second docking rod 102 on the drive motor 10 is inserted into the second limiting hole on the top surface of the second end of the second locking assembly 7. The command button 14 is pressed to send the start command to the PLC control board 13 to control the start of the drive motor 10. The drive motor 10 will then drive the second locking assembly 7 to rotate relative to the second end of the wrench body through the second docking rod 102. The rotation of the second locking assembly 7 will drive the entire screwing head (first mounting post 1, connecting post 111, screwing seat 112) to rotate, thereby realizing the automatic screwing of the bolt.

[0050] In a preferred embodiment, the wrench body includes a rotating tube 9 and a fixed tube 8. The rotating tube 9 is rotatably connected to the fixed tube 8. The rotating tube 9 has an internal thread, and the drive motor 10 has an external thread. The drive motor 10 is screwed onto the rotating tube 9.

[0051] Specifically, the top and bottom surfaces of the rotating tube 9 have limiting components, and the fixed tube 8 has a third limiting hole corresponding to the limiting components, with the limiting components inserted into the third limiting hole. Rotating the rotating tube 9 causes it to rotate relative to the fixed tube 8, and at the same time, the rotating tube 9 drives the drive motor 10 to move.

[0052] Preferably, the outer walls of the rotating tube 9 and the fixed tube 8 are respectively formed with circumferential flanges, and corresponding holes are opened on the two flanges, with limiting rods 92 passing through the holes. The limiting rods 92 play a role in limiting and fixing the rotating tube 9 and the fixed tube 8. Pulling out the limiting rods 92 can release the limiting and fixing of the rotating tube 9 and the fixed tube 8, at which point the rotating tube 9 can be screwed.

[0053] Preferably, a limiting ring 91 is formed circumferentially on the outer wall of the fixed tube 8. The limiting ring 91 has an internal thread, and the outer wall of the fixed tube 8 has an external thread. The limiting ring 91 is screwed onto the fixed tube 8. A fourth limiting hole is provided on the limiting ring 91 corresponding to the limiting rod 92, and the limiting rod 92 is inserted into the fourth limiting hole. Specifically, rotating the limiting ring 91 moves it away from the limiting rod 92 until the limiting rod 92 disengages from the openings on the two flange rings. At this point, the rotating tube 9 can be rotated to drive the drive motor 10 to move.

[0054] In a preferred embodiment, the wrench body further includes a third mounting post 12 connected to one end of the fixed tube 8. The first end of the first locking assembly 11 is rotatably connected to the inner top surface of the first end of the wrench body, i.e., the inner top surface of the third mounting post 12. The second end of the first locking assembly 11 is connected to a first connecting rod 101 on the first drive shaft of the drive motor 10. One end of the first connecting rod 101 is connected to a plug-in block, and the second end of the first locking assembly 11 forms a corresponding plug-in hole, into which the plug-in block is inserted. The second end of the first locking assembly has an external thread. The movable plate 121 includes a clamping part and a moving part 122. The moving part 122 has a corresponding internal thread. The second end of the first locking assembly 11 is screwed onto the moving part 122, and the end of the moving part 122 away from the clamping part slides within the third mounting post 12.

[0055] Specifically, such as Figure 6 As shown, a limiting plate 124 is provided at the end of the moving part 122 away from the clamping part. The third mounting post 12 is provided with limiting flanges symmetrically corresponding to the limiting plate 124 to limit the limiting plate 124. A sliding space is formed between the two limiting flanges. The limiting plate 124 is inserted into the sliding space so that the limiting plate 124 slides only relative to the fixed plate 123 within the sliding space.

[0056] like Figure 1As shown, the rotating limiting ring 91 moves away from the limiting rod 92 until the limiting rod 92 disengages from the openings on the two flange rings. At this time, the rotating tube 9 is rotated to drive the drive motor 10 to move until the first docking rod 101 of the drive motor 10 is connected to the first locking assembly 11. Pressing the command button 14 causes the first drive shaft of the drive motor 10 to rotate, which in turn drives the first locking assembly 11 to rotate. The first locking assembly 11 rotates relative to the movable plate 121, thereby driving the movable plate 121 to move along the first locking assembly 11 relative to the fixed plate 123.

[0057] Preferably, the wrench body also includes a fourth mounting post connected to one end of the third mounting post 12, wherein a battery 15 is installed in the fourth mounting post.

[0058] The screw-tightening wrench of the present invention, with a bolt clamping structure, when using the first end of the wrench body to tighten a bolt, firstly rotates the limiting ring 91 until the limiting rod 92 disengages from the openings on the two flange rings, then rotates the rotating tube 9 to drive the drive motor 10 to move until the first docking rod 101 of the drive motor 10 connects with the first locking component 11. Pressing the command button 14 causes the first drive shaft of the drive motor 10 to rotate, which in turn drives the first locking component 11 to rotate. The first locking component 11 rotates relative to the movable plate 121, which drives the movable plate 121 to move along the first locking component 11 relative to the fixed plate 123, thereby enabling the movable plate 121 and the fixed plate 123 to clamp the bolt. Then, turning the wrench body loosens the bolt.

[0059] When using the second end of the wrench body to tighten the bolt, first rotate the rotating tube 9 to drive the drive motor 10 to move until the first connecting rod 101 of the drive motor 10 separates from the first locking component 11, and the first connecting rod 102 connects to the second locking component 7. Then, align the tightening seat 112 with the groove of the bolt head, and rotate the threaded sleeve 21 to move the suction cup 2 to the point where the two abut. Then, start the vacuum pump 31 to suck out the air inside the suction cup 2 through the suction pipe 32 and the air extraction hole 33, so that a vacuum space is formed between the suction cup 35 and the bolt, thus completing the flexible clamping of the bolt. Next, press the command button 14 to rotate the second drive shaft of the drive motor 10. The drive motor 10 will then drive the second locking component 7 to rotate relative to the second end of the wrench body via the second docking rod 102. The rotation of the second locking component 7 will drive the entire screw-tightening head (first mounting post 1, connecting post 111, screw-tightening seat 112) to rotate. The screw-tightening seat 112 will then screw the bolt head, thereby unscrewing the bolt. Finally, after unscrewing the bolt, move the wrench body to the top of the toolbox, turn off the vacuum device 3, and the worker can grasp the bolt and apply downward force to make it fall into the toolbox for collection.

[0060] The screw-tightening wrench of the present invention, featuring a bolt clamping structure, includes a drive motor comprising a coaxial first drive shaft and a second drive shaft, which moves between the first and second ends of the wrench body. When the first end of the wrench body is used to tighten a bolt, the first drive shaft of the drive motor drives a movable plate to move relative to a fixed plate to clamp the bolt, allowing the first end of the wrench body to tighten the bolt. When the second end of the wrench body is used to tighten a bolt, the second drive shaft of the drive motor drives a tightening head to rotate to unscrew the bolt. During bolt tightening, a suction cup is moved to the point of contact with the bolt, creating a vacuum in the suction cup. This allows the suction cup to flexibly clamp the bolt, preventing it from falling off during tightening.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
