Description

Technical Field

[0001] This application relates to the technical field of riveting devices, and in particular, to an automatic rotary riveting and pressing device. Background Art

[0002] Riveting is one of the most common connection processes. Riveting is divided into single-point riveting and multi-point riveting. Single-point riveting is simple to operate and has a low cost. It can be applied to various sizes and shapes of connecting parts, with a wide range of applications. However, single-point riveting is a single operation, with low efficiency and is not suitable for mass production of products. Multi-point riveting can solve the problem of low efficiency of single-point riveting, with high efficiency and is suitable for mass production. Common riveting devices mainly include single-station riveting machines and multi-station rotary riveting machines. Single-station riveting machines have a simple structure, but can only process one workpiece at a time, with low efficiency. Multi-station rotary riveting machines achieve multi-station operations through a rotating table, thereby improving the riveting efficiency.

[0003] A multi-station rotary riveting machine usually includes a rotating table: along with the stamping cycle of the stamping head, the stamping head rotates periodically: periodically stamps the workpiece on the tooling fixture. Workpiece: the part to be processed. Tooling fixture: used to clamp and fix the workpiece. Fixture table: fixes the tooling fixture, and one fixture table corresponds to one station; during the riveting process, the stamping head forms a complete riveting cycle from the completion of downward pressing for riveting to the completion of upward movement. During this cycle, the rotating table will rotate at the frequency of the riveting cycle, and the rotation angle is the interval angle between two stations. This angle can be set according to the actual needs of the workers to adapt to different production requirements. Up to 6 stations can be operated simultaneously. When a workpiece is completed with riveting, it will move in front of the worker as the rotating table rotates. At this time, the worker can remove the workpiece that has been completed with riveting and continue to install new workpieces and rivets on the fixture to prepare for the next round of riveting operations.

DETAILED DESCRIPTION

[0019] The following is combined with Figure 1 -Attached Figure 6 This application is described in further detail.

[0020] The present application embodiment discloses an automatic rotary riveting device. Figure 1 andFigure 2 , the automatic rotary riveting press equipment includes a frame 1, a workbench 2, a rotary table 3, a fixture table 4, a tooling fixture 5 and a punching head 6. The workbench 2 is arranged on the frame 1, the rotary table 3 is arranged on the workbench 2, the fixture table 4 is arranged on the rotary table 3 and there are multiple fixture tables 4. The tooling fixture 5 is arranged on the fixture table 4. The rotary table 3 is rotatably arranged on the workbench 2. Further, a first motor is arranged on the workbench 2, and the center line of the rotary table 3 is arranged on the output shaft of the first motor. The punching head 6 is arranged on the frame 1 and is slidably arranged on the frame 1. The punching head 6 is driven by a hydraulic cylinder arranged on the frame 1. The punching head 6 slides towards the fixture table 4 to rivet the rivet 8 on the workpiece 7.

[0021] During the riveting process of the punching head 6, from the completion of downward pressing for riveting to the completion of rising, a complete riveting cycle is formed. During this cycle, the rotary table 3 will rotate at the frequency of the riveting cycle, and the rotation angle is the interval angle between two stations. This angle can be set according to the actual needs of the workers to adapt to different production requirements. Multiple stations can be operated simultaneously at most. When a workpiece 7 is completed with riveting, it will move in front of the worker as the rotary table 3 rotates. At this time, the worker can remove the workpiece 7 that has been completed with riveting and continue to install a new workpiece 7 and rivet 8 on the fixture to prepare for the next round of riveting operation. Such a process not only improves production efficiency but also ensures the continuity and smoothness of the operation.

[0022] Refer to Figure 1 and Figure 3 , to improve the feeding efficiency of the rivet 8 while improving the operation safety of the staff, a material box 9 for placing the rivet 8 is arranged on the workbench 2. The material box 9 is located on one side of the workbench 2. An installation frame 10 is arranged above the material box 9. The installation frame 10 is a rectangular frame. A plurality of steel wire ropes 11 are arranged in the installation frame 10. The steel wire ropes 11 are in a straightened state. The steel wire ropes 11 are parallel to each other and parallel to the length direction of the installation frame 10. Adjacent steel wire ropes 11 are spaced apart for hanging the rivet 8; Refer to Figure 1 , Figure 3 and Figure 4 , a plurality of feeding pipes 12 are arranged on the installation frame 10. The feeding pipes 12 are located between adjacent steel wire ropes 11 and on one side of the installation frame 10. The feeding pipes 12 are spaced apart. The rivet 8 clamped between the steel wire ropes 11 slides along the steel wire ropes 11 and enters the feeding pipe 12 and moves along the feeding pipe 12. Further, a T-shaped groove is opened in the inner frame of the installation frame 10. The feeding pipe 12 communicates with the T-shaped groove. The steel wire ropes 11 are fixedly connected to the bottom wall of the T-shaped groove. A feeding notch 13 is opened on the feeding pipe 12. The diameter of the steel wire ropes 11 located in the T-shaped groove gradually decreases, so that the rivet 8 falls into the feeding pipe 12 through the feeding notch 13; The outlet end of the material conveying pipe 12 is provided with a closing member, and the closing member is used to open and close the outlet end of the material conveying pipe 12 to insert the rivet 8 into the connection port of the workpiece 7.

[0023] When loading the rivets 8, first pour a batch of rivets 8 onto the steel wire rope 11, then adjust the position of the rivets 8 on the steel wire rope 11 so that the rivets 8 are suspended on the steel wire rope 11, and then move the excess rivets 8 out of the steel wire rope 11 and drop them into the material box 9. Then push the rivets 8 to make the rivets 8 slide along the steel wire rope 11. When the rivets 8 move to the inner frame of the installation frame 10, the rivets 8 enter the material conveying pipe 12 through the T-shaped groove. The rivets 8 move in the material conveying pipe 12 to the port of the material conveying pipe 12. At this time, the closing member closes the port of the material conveying pipe 12. The operator holds the material conveying pipe 12 and aligns it with the connection hole on the workpiece 7, and then opens the port of the material conveying pipe 12 through the closing member. The rivets 8 in the material conveying pipe 12 are inserted into the connection hole through the material conveying pipe 12, and the loading operation of the rivets 8 is completed, with simple and convenient operation.

[0024] Refer to Figure 3 Refer to

[0025] When it is necessary to adjust the position of the rivets 8 on the steel wire rope 11, start the rotating motor 15. The rotating motor 15 drives the installation frame 10 to swing reciprocally within a certain angle. When the installation frame 10 swings, it drives the rivets 8 to slide on the steel wire rope 11. At this time, the rivets 8 that are not suspended in the steel wire rope 11 move in the installation frame 10, so that the remaining rivets 8 enter the steel wire rope 11 and the rivets 8 are suspended in the steel wire rope 11. Further, when it is necessary to remove the excess rivets 8 on the installation frame 10, start the rotating motor 15 to increase the inclination angle of the installation frame 10, so that the excess rivets 8 fall from the installation frame 10 into the material box 9. At the same time, the inverted rivets 8 fall from the installation frame 10 due to the center of gravity being above the steel wire rope 11, which facilitates the subsequent loading operation of the rivets 8 and improves the loading accuracy of the rivets 8.

[0026] Refer to Figure 3In the embodiment of the present application, a transfer box 16 is provided in the material box 9 and on the installation frame 10. The transfer box 16 located in the material box 9 is slidably arranged in the material box 9. Furthermore, a removal notch 17 for the transfer box 16 to be moved out is provided on the side wall of the material box 9. The transfer box 16 located on the installation frame 10 is snapped onto the installation frame 10. The transfer box 16 includes a rectangular enclosing frame 161 and a closing plate 162 arranged in the enclosing frame 161. The closing plate 162 is located in the lower middle part of the enclosing frame 161 and closes the bottom of the enclosing frame 161. The closing plate 162 is slidably arranged in the enclosing frame 161. The side wall of the enclosing frame 161 is provided with a sliding hole for the closing plate 162 to be slidably inserted. Reference Figure 3 After the closing plate 162 slides into the enclosing frame 161, the closing plate 162 is flush with the side wall of the enclosing frame 161, the enclosing frame 161 is snapped onto the mounting frame 10, and the transfer box 16 is placed in the material box 9. After the closing plate 162 opens the enclosing frame 161, the rivet 8 falls on the wire rope 11 and hangs on the wire rope 11, and falls into the transfer box 16 in the material box 9 as the mounting frame 10 swings.

[0027] After the transfer box 16 is clamped on the installation frame 10, the closing plate 162 is pulled to open the bottom of the enclosing frame 161. At this time, the rivet 8 on the closing plate 162 falls on the wire rope 11, and then the angle of the installation frame 10 is adjusted by rotating the motor 15, so that the rivet 8 is suspended on the wire rope 11, and then the enclosing frame 161 is removed from the installation frame 10, and the excess rivets 8 fall from the installation frame 10 into the material box 9 and enter the transfer box 16. When all the rivets 8 on the wire rope 11 are transferred to the feed pipe 12, the transfer box 16 in the material box 9 is clamped on the installation frame 10, and the transfer box 16 from the installation frame 10 is transferred to the transfer box 16.

[0028] Reference Figure 3 In order to ensure that the transfer box 16 places the rivets 8 while facilitating a certain distance between the closing plate 162 and the wire rope 11, so as to facilitate the rivets 8 to enter between adjacent wire ropes 11 when falling, when the closing plate 162 opens the surrounding frame 161, all the rivets 8 fall on the wire rope 11, resulting in insufficient space for the rivets 8 to adjust their positions. Therefore, in the embodiment of the present application, a clamping groove 18 for clamping the bottom of the surrounding frame 161 is provided at the top of the mounting frame 10, and a movable plate is slidably arranged in the mounting frame 10 and located in the clamping groove 18, and a plurality of plug-in rods 19 are provided on the movable plate, and a fixing hole for plugging the plug-in rods 19 is provided at the bottom of the surrounding frame 161, and the movable plate is slidably arranged in the clamping groove 18, and a first driving member for driving the movable plate to slide is provided on the mounting frame 10, and the first driving member includes an electric push rod 20 arranged at the bottom of the mounting frame 10, and the movable plate is fixedly arranged on the output shaft of the electric push rod 20.

[0029] After the closing plate 162 opens with respect to the surrounding frame 161, the mounting frame 10 swings reciprocally to adjust the position of the rivet 8. Subsequently, the electric push rod 20 is activated, and the electric push rod 20 pushes the moving plate to move along the depth direction of the clamping groove 18. The rising of the moving plate drives the surrounding frame 161 to move upward, thereby increasing the distance between the closing plate 162 and the steel wire rope 11, and providing sufficient space for the rivet 8 to adjust its position; after the position of the rivet 8 is adjusted, the surrounding frame 161 is moved upward again through the electric push rod 20 to disengage the surrounding frame 161 from the mounting frame 10, facilitating the removal of the rivet 8 through the gap between the surrounding frame 161 and the mounting frame 10 into the material box 9.

[0030] To facilitate the collection of the falling rivets 8 by the material box 9, the top of the material box 9 is open to receive the rivets 8 dropped from the mounting frame 10.

[0031] Refer to Figure 3 、 Figure 5 and Figure 6 In the embodiment of the present application, the material conveying pipe 12 includes a soft pipe 121 and a hard pipe 122. The soft pipe 121 is arranged on the mounting frame 10, and the hard pipe 122 is coaxially arranged on the soft pipe 121. The opening and closing member includes an opening and closing plate 21 slidably arranged at the end of the hard pipe 122. The opening and closing plate 21 is slidably inserted into the hard pipe 122, and the sliding direction of the opening and closing plate 21 is perpendicular to the axial direction of the hard pipe 122. The opening and closing member further includes a second driving member for driving the opening and closing plate 21 to slide to open and close the hard pipe 122; the soft pipe 121 facilitates the staff to adjust the position of the hard pipe 122, facilitating the alignment of the hard pipe 122 with the connecting hole of the workpiece 7; and it is convenient for the staff to hold the hard pipe 122 to convey the rivets 8 into the connecting hole.

[0032] Refer to Figure 3 、 Figure 5 and Figure 6, since the number of required rivets 8 on a workpiece 7 is large, and the rivets 8 are in an overlapping state in the material conveying pipe 12, when the hard pipe 122 is opened, it is difficult to control the falling of the rivets 8, which easily causes the excess rivets 8 to move out of the hard pipe 122. Therefore, in the embodiment of the present application, in order to facilitate the movement of the required number of rivets 8 out of the hard pipe 122 after the hard pipe 122 is opened, a positioning fork 22 is provided on the hard pipe 122. The positioning fork 22 is a plate-shaped structure with an opening. An access hole 23 for the positioning fork 22 to enter is provided on the hard pipe 122. After the positioning fork 22 enters the hard pipe 122, the heads of the rivets 8 are received in the positioning fork 22. The positioning fork 22 is slidably arranged on the hard pipe 122, and the sliding direction of the positioning fork 22 is perpendicular to the axial direction of the hard pipe 122; the positioning fork 22 is inserted into the hard pipe 122, and the positioning fork 22 in the hard pipe 122 is fixed in the hard pipe 122. At this time, the number of rivets 8 between the opening and closing plate 21 and the positioning fork 22 is the same as the number required for one workpiece 7. Subsequently, the opening and closing plate 21 opens the hard pipe 122. After the hard pipe 122 is opened, the rivets 8 gradually move out through the hard pipe 122 and are then inserted into the connection holes.

[0033] Referring to Figure 3 , Figure 5 and Figure 6 , in the embodiment of the present application, the sliding direction of the positioning fork 22 is parallel to the sliding direction of the opening and closing plate 21 and opposite to the sliding direction of the opening and closing plate 21. The second driving member is used to drive the sliding of the opening and closing plate 21 and drive the sliding of the positioning fork 22 at the same time. The second driving member includes a first airbag 24, a second airbag 25 and a third airbag 26. The first airbag 24 surrounds the hard pipe 122 and is fixedly arranged on the hard pipe 122. The second airbag 25 corresponds to the opening and closing plate 21, and the third airbag 26 corresponds to the positioning fork 22. The opening and closing plate 21 and the positioning fork 22 are respectively located on both sides of the hard pipe 122. The second airbag 25 is parallel to the third airbag 26. The opening and closing plate 21 is fixedly arranged on the second airbag 25, and the positioning fork 22 is fixedly arranged on the third airbag 26. The second driving member further includes a first air pipe 27 and a second air pipe 28. The first air pipe 27 communicates the first airbag 24 and the second airbag 25, and the second air pipe 28 communicates the first airbag 24 and the third airbag 26. The communication end of the first air pipe 27 with the second airbag 25 is close to the hard pipe 122, and the communication end of the second air pipe 28 with the third airbag 26 is away from the hard pipe 122. Further, the second airbag 25 is close to the hard pipe 122, the third airbag 26 is away from the hard pipe 122. A pushing block 29 is arranged on the top surface of the opening and closing plate 21. The second airbag 25 is located between the pushing block 29 and the hard pipe 122, and the third airbag 26 is located at the end of the positioning fork 22 away from the hard pipe 122.

[0034] When the opening and closing plate 21 closes the rigid pipe 122, the positioning fork 22 is located outside the rigid pipe 122. When it is necessary to open the rigid pipe 122, the first airbag 24 is pressed, and the gas in the first airbag 24 enters the second airbag 25 and the third airbag 26 through the first air pipe 27 and the second air pipe 28. The volume of the second airbag 25 expands, and the second airbag 25 pushes the pushing block 29 to drive the opening and closing plate 21 to slide and open the rigid pipe 122. At the same time, the volume of the third airbag 26 expands, and the third airbag 26 expands to push the positioning fork 22 into the rigid pipe 122 to fix the upper rivet 8, so as to facilitate the removal of the lower rivet 8; when the volume of the first airbag 24 is restored, the gas in the second airbag 25 and the third airbag 26 returns to the first airbag 24, the volumes of the second airbag 25 and the third airbag 26 decrease, the third airbag 26 pulls the positioning fork 22 out of the rigid pipe 122, and the second airbag 25 pulls the pushing block 29 to drive the opening and closing plate 21 to insert into the rigid pipe 122.

[0035] Refer to Figure 3 , Figure 5 and Figure 6 , to facilitate the restoration of the volume of the first airbag 24, a spring 30 is further included. The spring 30 drives the opening and closing plate 21 and the positioning fork 22 in the direction opposite to the pushing direction of the second airbag 25 and the third airbag 26, so that the gas in the second airbag 25 and the third airbag 26 returns to the first airbag 24.

[0036] Refer to Figure 3 , Figure 5 and Figure 6 , to adjust the position of the positioning fork 22, and thus adjust the number of rivets 8 between the positioning fork 22 and the opening and closing plate 21. An installation frame 31 is slidably arranged on the rigid pipe 122, the positioning fork 22 is slidably arranged on the installation frame 31, the third airbag 26 is located between the installation frame 31 and the positioning fork 22, the installation frame 31 is slidably arranged on the rigid pipe 122, and the installation frame 31 slides along the length direction of the rigid pipe 122; a plurality of inlet holes 23 are opened and evenly arranged along the length direction of the rigid pipe 122; further, a pipe clamp is arranged on the installation frame 31, and the pipe clamp is sleeved on the rigid pipe 122 to facilitate fixing the installation frame 31 at the adjusted position.

[0037] The implementation principle of an automatic rotary riveting and pressing device in an embodiment of this application is as follows: When loading the rivets 8, first pour a batch of rivets 8 onto the steel wire rope 11, and then adjust the position of the rivets 8 on the steel wire rope 11 so that the rivets 8 are suspended on the steel wire rope 11; start the rotating motor 15, and the rotating motor 15 drives the mounting frame 10 to swing reciprocally within a certain angle. When the mounting frame 10 swings, it drives the rivets 8 to slide on the steel wire rope 11. At this time, the rivets 8 that are not suspended inside the steel wire rope 11 move inside the mounting frame 10, causing the remaining rivets 8 to enter the steel wire rope 11 and making the rivets 8 suspended inside the steel wire rope 11; further, when it is necessary to remove the excess rivets 8 on the mounting frame 10, start the rotating motor 15 to increase the inclination angle of the mounting frame 10, so that the excess rivets 8 fall from the mounting frame 10 into the material box 9. Subsequently, push the rivets 8 to make the rivets 8 slide along the steel wire rope 11. When the rivets 8 move to the inner frame of the mounting frame 10, the rivets 8 enter the material conveying pipe 12 through the T-shaped groove. The rivets 8 move inside the material conveying pipe 12 to the port of the material conveying pipe 12. At this time, the opening and closing plate 21 closes the port of the material conveying pipe 12. The worker holds the material conveying pipe 12 and aligns it with the connecting hole on the workpiece 7, and then opens the port of the material conveying pipe 12 through the opening and closing plate 21. The rivets 8 inside the material conveying pipe 12 are inserted into the connecting hole through the material conveying pipe 12, thus completing the rivet loading operation, which is simple and convenient.

[0038] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
