Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of FDS connection, in particular to an FDS flow drill tightening device. Background Art
[0002] FDS stands for flow drill screw tightening process, also known as self-tapping screw connection or hot melt self-tapping connection. The FDS process uses the central tightening shaft of the FDS equipment to transmit the high-speed rotational motion of the servo motor to the screw. The screw acts on the plates to be connected, generating frictional heat. Under the action of huge axial pressure, the material undergoes plastic deformation. Under the pressure of the flow drill screw, a cylindrical through hole is formed. The screw tip pierces the plate to be connected and screws into the plate to be connected. Drilling, tapping, and tightening are completed in one process on the FDS equipment, and finally a fully meshed threaded connection is formed between the plate and the screw.
[0003] The existing FDS flow drill tightening equipment has the main problem during use. When the screw slips during high-speed tightening, the slipped screw cannot be removed in time, thereby delaying subsequent connection work. Secondly, the existing FDS flow drill tightening equipment does not have the function of quickly disassembling the high-speed tightening mechanism during use. Therefore, when the high-speed tightening mechanism is damaged or fails, it cannot be quickly replaced and repaired, thereby affecting the connection efficiency. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the utility model provides an FDS flow drill tightening device, which has the advantages of easy removal of slipping screws and easy disassembly and maintenance, and solves the problems raised by the above background technology.
[0005] The cam is provided with a toothed plate at the top end of the support frame, and a toothed plate is provided at the bottom end of the support frame, wherein the toothed plate is provided with a toothed plate at the top end of the support frame, and a toothed plate is provided at the bottom end of the support frame.
[0006] As an optimal technical solution of the present invention: the limiting block 1 is slidably connected to the inner wall of the limiting groove 1, and one end of the spring is fixedly installed on the outside of the block and the other end is fixedly installed on the inner wall of the clamping block.
[0007] As an optimal technical solution of the present invention: clamping slots are provided on both sides of the high-speed tightening mechanism, and the clamping block is clamped with the high-speed tightening mechanism through the clamping slots.
[0008] As a preferred technical solution of the present invention: support legs are fixedly installed on the bottom of the support plate, and the number of the support legs is four.
[0009] As an optimal technical solution of the present invention: a controller is fixedly installed on the outer side of the support frame, and the high-speed tightening mechanism and the negative pressure fan are both electrically connected to the controller.
[0010] As an optimal technical solution of the present invention: a second limiting groove is provided on the inner wall of the arc-shaped groove, and a second limiting block is fixedly installed on the outer edge of the rotating rod.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. The FDS flow drill tightening equipment is used in conjunction with the exhaust pipe and the negative pressure fan. When the negative pressure fan is controlled by the controller to work, the impeller inside the negative pressure fan is used to generate a negative pressure effect, thereby generating suction inside the exhaust pipe. When the high-speed tightening mechanism is tightening the screw, if the screw slips, the high-speed tightening mechanism can be rotated in the opposite direction to drive the screw out. At this time, the extracted screw is sucked into the interior of the exhaust pipe through the work of the negative pressure fan. Subsequently, the sucked screw is blocked by the block and the drop groove is opened, causing the sucked screw to fall into the inner wall of the collection frame, thereby achieving the purpose of removing and collecting the screw.
[0013] 2. The FDS flow drill tightening device, through the cooperation of the card block and the card slot, when it is necessary to repair or replace the high-speed tightening mechanism, it is only necessary to pull the card block outward so that the card block slides outward on the outside of the block. Through the cooperation of the limit block 1 and the limit slot 1, the sliding of the card block can be limited to prevent the card block from being directly pulled out of the outer wall of the block. At this time, the card block slides out of the inner wall of the card slot, so that the high-speed tightening mechanism can be removed, which is convenient for repair and replacement of the high-speed tightening mechanism. When the repair and replacement is completed, it is only necessary to pull the card block outward so that the inner wall of the card block pulls the spring to deform, thereby stretching the spring. When the high-speed tightening mechanism slides to the same horizontal line as the card block, it is only necessary to loosen the card block. The limit of the limit slot 1 and the limit block 1, as well as the elastic potential energy of the spring itself, can complete the clamping and fixation of the high-speed tightening mechanism.
[0014] 3. The FDS flow drill tightening device uses a torsion spring and a rotating rod. When a certain number of screws accumulate on the inner wall of the collection frame, the rotating rod can be rotated to rotate toward either side of the inner wall of the arc groove. At this time, the second limit block on the outer edge of the rotating rod rotates together with the inner wall of the second limit groove. When it reaches the end of either side, the collection frame can be removed, and the torsion spring can be set to automatically return to its original position. BRIEF DESCRIPTION OF THE DRAWINGS

When the high-speed tightening mechanism 4 is tightening the screw, if the screw slips, the high-speed tightening mechanism 4 can be rotated in the reverse direction to drive the screw to be extracted. At this time, the extracted screw can be sucked into the interior of the suction pipe 11 through the operation of the negative pressure fan 12, and then passed through the block 13 The obstruction and the opening of the drop groove 14 cause the sucked screws to fall into the inner wall of the collection frame 15. When a certain number of screws accumulate on the inner wall of the collection frame 15, the rotating rod 17 can be rotated to rotate the rotating rod 17 on the inner wall of the arc groove 16 toward either side. At this time, the limit block 20 on the outer edge of the rotating rod 17 rotates together on the inner wall of the limit groove 2 19. When it reaches the end of either side, the collection frame 15 can be removed, and the setting of the torsion spring 18 can make the rotating rod 17 automatically return to its original position.
[0025] In a preferred embodiment: the limiting block 9 is slidably connected to the inner wall of the limiting groove 7, and one end of the spring 10 is fixedly installed on the outside of the block 8 and the other end is fixedly installed on the inner wall of the clamping block 6.
[0026] In the above structure, the sliding of the block 6 is limited by the limiting groove 1 7 to prevent the block 6 from directly sliding out of the outer wall of the block 8.
[0027] In a preferred embodiment, a clamping slot 5 is provided on both sides of the high-speed tightening mechanism 4 , and the clamping block 6 is clamped to the high-speed tightening mechanism 4 through the clamping slot 5 .
[0028] In the above structure, by providing the clamping slot 5 , the clamping block 6 can clamp and fix the clamping slot 5 , thereby allowing the high-speed tightening mechanism 4 to work normally.
[0029] In a preferred embodiment, support legs 2 are fixedly mounted on the bottom of the support plate 1 , and the number of the support legs 2 is four.
[0030] In the above structure, the four supporting legs 2 are provided so that the supporting legs 2 can stably support the supporting plate 1 .
[0031] In a preferred embodiment, a controller 22 is fixedly mounted on the outer side of the support frame 3 , and the high-speed tightening mechanism 4 and the negative pressure fan 12 are both electrically connected to the controller 22 .
[0032] In the above structure, by setting the controller 22, the high-speed tightening mechanism 4 and the negative pressure fan 12 can be controlled by the controller 22, so that the high-speed tightening mechanism 4 and the negative pressure fan 12 can work or stop working.
[0033] In a preferred embodiment, a second limiting groove 19 is formed on the inner wall of the arc-shaped groove 16 , and a second limiting block 20 is fixedly installed on the outer edge of the rotating rod 17 .
[0034] In the above structure, by providing the second limiting groove 19 and the second limiting block 20 , and utilizing the sliding connection between the second limiting block 20 and the second limiting groove 19 , the rotating rod 17 can slide smoothly on the inner wall of the arc groove 16 .
[0035] Working principle: However, when it is necessary to use this device, the exhaust pipe 11 and the negative pressure fan 12 can be set first, and then the negative pressure fan 12 can be controlled by the controller 22 to work, and the impeller inside the negative pressure fan 12 is used to generate a negative pressure effect, thereby generating suction inside the exhaust pipe 11. When the high-speed tightening mechanism 4 is in the process of tightening the screw, if the screw slips, the high-speed tightening mechanism 4 can be rotated in the opposite direction, thereby driving the screw to be pulled out. At this time, the pulled-out screw is sucked into the interior of the exhaust pipe 11 by the work of the negative pressure fan 12, and then blocked by the stopper 13 and the opening of the drop groove 14, causing the sucked-in screw to fall into the inner wall of the collection frame 15. When a certain number of screws are accumulated on the inner wall of the collection frame 15, the rotating rod 17 can be rotated to either side of the inner wall of the arc groove 16 by rotating the rotating rod 17. At this time, the limit block 20 on the outer edge of the rotating rod 17 rotates together with the inner wall of the limit groove 19. When it reaches the end of either side, the collection frame 15 can be removed, and the torsion spring 18 is set to automatically return the rotating rod 17 to its original position. Secondly, when the high-speed tightening mechanism 4 needs to be repaired or replaced, it is only necessary to pull the card block 6 outward so that the card block 6 slides outward on the outside of the block 8. The cooperation of the limit block 9 and the limit slot 7 can limit the sliding of the card block 6, preventing the card block 6 from being directly pulled out of the outer wall of the block 8. At this time, the card block 6 slides out of the inner wall of the card slot 5. , so that the high-speed tightening mechanism 4 can be removed, which facilitates the maintenance and replacement of the high-speed tightening mechanism 4. When the maintenance and replacement is completed, it is only necessary to pull the block 6 outward so that the inner wall of the block 6 pulls the spring 10 to deform, thereby stretching the spring 10. When the high-speed tightening mechanism 4 slides to the point where the block 6 is on the same horizontal line, it is only necessary to loosen the block 6, the limiting groove 7 and the limiting block 9, and the elastic potential energy of the spring 10 itself, thereby completing the clamping and fixing of the high-speed tightening mechanism 4.
