Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, specifically to a pipe riveting device. Background Technology

[0002] Flexible hose connections are a type of connection that uses flexible pipes and their accessories to transmit fluids or sometimes power in mechanical, equipment, or piping systems. They solve problems that rigid connections struggle with, such as vibration, displacement, and installation errors. They are used in various fields, such as motorcycle braking systems. When installing a flexible hose, connectors are usually installed at both ends of the pipe for connection. After the connectors are inserted into the hose, they are usually riveted to deform and fix the connectors to the ends of the hose. Current riveting methods involve workers manually riveting with hand-held riveting tools, which is very troublesome, wastes manpower, and is inefficient. Utility Model Content

[0003] In summary, to overcome the shortcomings of the prior art, this utility model provides a more efficient pipe riveting device.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a riveting device for a pipe body, comprising a riveting frame, a ninth driving member, a sixth push-pull machine, and a plurality of riveting blocks. The riveting frame is provided with riveting holes, and the plurality of riveting blocks are located in the riveting holes. The ninth driving member controls the riveting blocks to reciprocate toward the center of the riveting holes, and the sixth push-pull machine controls the riveting frame to reciprocate relative to the pipe body.

[0005] With this setup, during riveting, the sixth push-pull machine will control the tube to enter the riveting hole on the riveting frame. After entering, the ninth drive unit will drive several riveting blocks to move toward the joint on the tube until it is clamped and riveted. Then the riveting blocks will retract, and the sixth push-pull machine will pull the tube out. At this point, the joint will be riveted and deformed and fixed to the end of the tube. After that, it can continue to be transported to the rear. The whole process does not require manual operation and is more efficient.

[0006] Furthermore, the outer wall of the riveting frame is provided with a riveting groove that communicates with the riveting hole and is adapted to the riveting block, and the riveting groove is provided with a reset member that applies a force to the riveting block in the opposite direction to the riveting hole.

[0007] With this setup, the riveting block can be directly inserted into the riveting groove on the outer wall of the riveting frame during installation. When in use, simply push the riveting block from the outside to move it toward the center of the riveting hole to achieve the riveting effect. After riveting is completed, when the riveting block is no longer pushed, it will be pushed back to its original position by the reset component.

[0008] Furthermore, the riveting block is provided with a first strip groove, and the riveting block is provided with a positioning rod, which penetrates through the outer wall of the riveting frame and is inserted into the first strip groove.

[0009] With this setup, after inserting the rivet block into the rivet groove during installation, the positioning rod can be inserted through the rivet frame into the first slot. This restricts the movement of the rivet block within the range of the first slot and prevents it from being pushed out of the rivet groove by the reset component. This makes the structure more stable and easier to install. A detachable mounting block can also be set at the position where the rivet block is installed on the rivet frame to process the rivet groove, which facilitates processing and installation.

[0010] Furthermore, the riveting block has a reset groove on the side facing the riveting hole, and the riveting frame has a reset block at the bottom of the riveting groove. The reset element is a spring disposed between the reset block and the reset groove.

[0011] With this configuration, the spring will be in the reset slot, while the reset block is stable on the riveting frame. The force exerted by the spring on the riveting block can push the riveting block to move toward the opening of the riveting slot. The structure is simple and the reset is stable.

[0012] Furthermore, it also includes a top pressing component. The ninth driving component is a push-pull machine that controls the top pressing component to move toward the riveting frame. The side of the riveting block facing away from the center of the riveting hole is an inclined surface that is set toward the reduced diameter of the top pressing component. The top pressing component is provided with a top pressing block at the position corresponding to the inclined surface of the riveting block.

[0013] With this configuration, the ninth drive component can use conventional structures such as pneumatic push rods, electric push rods, and hydraulic push rods. When in use, it drives the top pressing component to move toward the riveting frame. After moving, the top pressing block will first contact the inclined surface of the riveting block exposed outside the riveting groove. In this way, during the pushing process, the riveting block will be driven to move toward the center of the riveting hole. The pushing process is stable. The position of the riveting groove on the riveting frame can also be set in a conical or frustum shape to facilitate the pushing of the top pressing component.

[0014] Furthermore, it also includes a second positioning pin, which is connected to the output shaft of the ninth drive unit.

[0015] With this setup, the second positioning pin will be inserted into the inner hole of the connector or pipe body for positioning during riveting. After the conical head of the second positioning pin is inserted into the inner hole, it will correct the end angle of the pipe body and connector, making them perpendicular to the riveting hole, thus making the riveting position more accurate.

[0016] Furthermore, the second positioning pin is slidably connected to the top pressing member. The second positioning pin is provided with a reset plate. A reset spring is provided on the side of the reset plate facing the top pressing member and sleeved on the outer wall of the second positioning pin. The above setting is not limited. The reset spring can also be other elastic structures such as spring sheets.

[0017] With this setup, the second positioning pin will be in an active state. When the ninth drive component moves, the second positioning pin will first contact the tube body and the connector. Then, the second positioning pin will compress the reset spring and move until the riveting is completed. During this period, the second positioning pin will always press against the connector to position it, but it will not damage the connector.

[0018] Furthermore, the pressing member is provided with a connecting block, the connecting block is provided with a reset hole adapted to the second positioning pin, the second positioning pin is provided with a second strip groove, the second positioning pin is provided with a positioning strip, and the positioning strip penetrates through the outer wall of the connecting block and is inserted into the second strip groove.

[0019] With this setup, during installation, the second positioning pin is inserted into the reset socket, and then the positioning strip is inserted through the outer wall of the connecting block into the second slot. In this way, the second positioning pin completes the sliding connection and is limited, so it will not pop out. Installation is convenient. The connecting block can be detachably connected to the top pressing part with bolts or other parts, which is convenient for processing. The reset socket can be a through hole, and the output shaft of the ninth drive part can also be set to be hollow to facilitate the movement of the second positioning pin.

[0020] Furthermore, a clamping assembly is provided at the output shaft position of the sixth push-pull machine, and the sixth push-pull machine is connected to the riveting frame on the side facing the tube body.

[0021] With this setup, the sixth push-pull machine will control the clamping assembly on the riveting frame to clamp the tube and move it toward the riveting groove. Since the riveting device is relatively heavy, it is easier to control the lighter tube. The riveting devices on both sides no longer operate at the same time, and the riveting effect can be achieved by using them separately.

[0022] Furthermore, it also includes a seventh push-pull machine, which is connected to the frame on the side of the tube body facing away from the riveting frame, and a clamping assembly is provided at the output shaft position of the seventh push-pull machine.

[0023] With this setup, the other end of the tube will be clamped by another clamping component, and then driven by the seventh push-pull machine to move together toward the riveting hole. The simultaneous clamping of both ends of the tube makes the movement more stable. Attached Figure Description

After reading this specification, those skilled in the art can make modifications to the present embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present embodiment.

[0033] Referring to the accompanying drawings, this utility model provides the following technical solution: a riveting device for a pipe body, comprising a riveting frame 501, a ninth driving member 502, a sixth push-pull machine 503, and a plurality of riveting blocks 504. The riveting frame 501 is provided with riveting holes 5011, and the plurality of riveting blocks 504 are located in the riveting holes 5011. The ninth driving member 502 controls the riveting blocks 504 to reciprocate toward the center of the riveting holes 5011. The sixth push-pull machine 503 controls the riveting frame 501 to reciprocate relative to the pipe body. The sixth push-pull machine 503 can be selected from conventional push-pull parts such as telescopic motors, telescopic cylinders, and hydraulic cylinders. Other push-pull machines in this application can also use the same selection as the sixth push-pull machine 503.

[0034] With this setup, during riveting, the sixth push-pull machine 503 will control the tube body to enter the riveting hole 5011 on the riveting frame 501. After entering, the ninth drive unit 502 drives several riveting blocks 504 to move toward the joint on the tube body until it is clamped and riveted. Then the riveting blocks 504 retract, and the sixth push-pull machine 503 pulls the tube body out. At this time, the joint will be fixed to the end of the tube body by the riveting deformation. Then it can continue to be transported to the rear. The whole process does not require manual operation and is more efficient.

[0035] In a preferred embodiment, the outer wall of the riveting frame 501 is provided with a riveting groove 5012 that communicates with the riveting hole 5011 and is adapted to the riveting block 504. The riveting groove 5012 is provided with a reset member 5013 that applies a force to the riveting block 504 in the opposite direction to the riveting hole 5011.

[0036] With this configuration, during installation, the rivet block 504 can be directly inserted from the rivet groove 5012 on the outer wall of the rivet frame 501. During use, simply push the rivet block 504 from the outside to move it toward the center of the rivet hole 5011 to achieve the riveting effect. After the riveting is completed, when the rivet block 504 is no longer pushed, it will be pushed back to its original position by the reset member 5013.

[0037] In a preferred embodiment, the riveting block 504 is provided with a first strip groove 5041, and the riveting block 504 is provided with a positioning rod 5042, which penetrates the outer wall of the riveting frame 501 and is inserted into the first strip groove 5041.

[0038] With this configuration, after inserting the rivet block 504 into the rivet groove 5012 during installation, the positioning rod 5042 can be inserted through the rivet frame 501 into the first strip groove 5041. This restricts the movement of the rivet block 504 within the range of the first strip groove 5041, preventing it from being pushed out of the rivet groove 5012 by the reset member 5013. This results in a more stable structure and easier installation. A detachable mounting block can also be provided at the position on the rivet frame 501 where the rivet block 504 is installed to process the rivet groove 5012, facilitating processing and installation.

[0039] In this preferred embodiment, the riveting block 504 has a reset groove 5043 on the side facing the riveting hole 5011, the riveting frame 501 has a reset block 5014 at the bottom of the riveting groove 5012, and the reset member 5013 is a spring disposed between the reset block 5014 and the reset groove 5043.

[0040] With this configuration, the spring will be in the reset groove 5043, while the reset block 5014 is stabilized on the riveting frame 501. The force exerted by the spring on the riveting block 504 can push the riveting block 504 to move toward the opening of the riveting groove 5012. The structure is simple and the reset is stable.

[0041] In this preferred embodiment, the reset block 5014 and the riveting frame 501 are detachably connected.

[0042] With this configuration, the riveting groove 5012 can be directly designed as a through hole, which makes it easier to process. The reset block 5014 can be connected to the riveting frame 501 by conventional methods such as bolt connection.

[0043] In a preferred embodiment, the device further includes a top pressing member 505. The ninth driving member 502 is a push-pull machine that controls the top pressing member 505 to move toward the riveting frame 501. The side of the riveting block 504 facing away from the center of the riveting hole 5011 is an inclined surface that is oriented toward the top pressing member 505 with a reduced diameter. The top pressing member 505 is provided with a top pressing block 5051 at the position corresponding to the inclined surface of the riveting block 504.

[0044] With this configuration, the ninth driving component 502 can use conventional structures such as pneumatic push rods, electric push rods, and hydraulic push rods. When in use, it drives the top pressing component 505 to move toward the riveting frame 501. After moving, the top pressing block 5051 will first contact the inclined surface of the riveting block 504 exposed outside the riveting groove 5012. In this way, during the pushing process, the riveting block 504 will be driven to move toward the center of the riveting hole 5011. The pushing process is stable. The position of the riveting groove 5012 on the riveting frame 501 can also be set in a conical or frustum shape to facilitate the pushing of the top pressing component 505.

[0045] In a preferred embodiment, a second positioning pin 506 is also included, which is connected to the output shaft of the ninth driving member 502.

[0046] With this configuration, the second positioning pin 506 will be inserted into the inner hole of the connector or pipe body for positioning during riveting. After the conical head of the second positioning pin 506 is inserted into the inner hole, it will straighten the end angle of the pipe body and connector so that they are perpendicular to the riveting hole 5011, making the riveting position more accurate.

[0047] In this preferred embodiment, the second positioning pin 506 is slidably connected to the top pressing member 505. The second positioning pin 506 is provided with a reset plate 5061. The reset plate 5061 is provided with a reset spring 5062 sleeved on the outer wall of the second positioning pin 506 on the side facing the top pressing member 505. The above setting is not limited, and the reset spring 5062 can also be other elastic structures such as spring sheets.

[0048] With this setup, the second positioning pin 506 will be in an active state. When the ninth drive component 502 moves, the second positioning pin 506 first contacts the tube body and the connector. Then, the second positioning pin 506 compresses the return spring 5062 and moves until the riveting is completed. During this period, the second positioning pin 506 always presses against the connector to position it, but will not damage the connector.

[0049] In a preferred embodiment, the top pressing member 505 is provided with a connecting block 5052, the connecting block 5052 is provided with a reset insertion hole 50521 adapted to the second positioning pin 506, the second positioning pin 506 is provided with a second strip groove 5063, the second positioning pin 506 is provided with a positioning strip 5064, and the positioning strip 5064 penetrates the outer wall of the connecting block 5052 and is inserted into the second strip groove 5063.

[0050] With this configuration, during installation, the second positioning pin 506 is inserted into the reset socket 50521, and then the positioning strip 5064 is inserted through the outer wall of the connecting block 5052 into the second strip groove 5063. In this way, the second positioning pin 506 completes the sliding connection and is limited, so it will not pop out, making installation convenient. The connecting block 5052 can be detachably connected to the top pressing part 505 with bolts or other parts, which is convenient for processing. The reset socket 50521 can be a through hole, and the output shaft of the ninth driving part 502 can also be set to be hollow to facilitate the movement of the second positioning pin 506.

[0052] With this setup, the sixth push-pull machine 503 will control the clamping assembly 2043 on the riveting frame 501 to clamp the tube body and move it toward the riveting groove 5012. Since the riveting device 5 is relatively heavy, it is easier to control the movement of the lighter tube body. The riveting devices 5 on both sides no longer operate at the same time, and the riveting effect can also be achieved by using them separately.

[0053] In a preferred embodiment, the seventh push-pull machine 507 is also included. The seventh push-pull machine 507 is connected to the frame 1 on the side of the tube body facing away from the riveting frame 501.
