Description

Technical Field

[0001] The invention belongs to the technical field of metal processing, and in particular relates to a full-automatic riveting device and a riveting process thereof. Background Art

[0002] Riveting is a commonly used connection method in mechanical processing. It is mainly used to connect two thin plates by drilling holes in them, putting rivets in them, and then using a mold to squeeze the rivets to deform them to achieve the purpose of riveting.

[0003] The prior art discloses some invention patents in the field of metal processing technology, among which Chinese patent CN105618656B discloses a combined stamping riveting method and device, including a positioning base, a riveting punch, a pre-compression sleeve, a pre-compression spring, a cylindrical pin and an adjusting rod; the positioning base is mounted on a press workbench, the riveting punch is clamped on the press rod, and the center line is aligned with the center line of the positioning base. During riveting, the punch contacts the rivet and causes the rivet to roll outward; the pre-compression sleeve, the pre-compression spring and the cylindrical pin are mounted on the riveting punch, and the pre-compression sleeve is pre-compressed by the pre-compression spring. The compression sleeve and pre-compression spring realize the pre-compression of the riveted thin plate parts and prevent the workpiece from being stuck on the riveting punch. The cylindrical pin connects the pre-compression sleeve and the pre-compression spring to the riveting punch to prevent them from falling off during work; the adjustment rod adjusts the positioning center line of the positioning base to align with the center line of the press rod. Compared with the existing riveting method, the combined stamping and riveting device uses a press to rivet the workpiece. The riveting of the workpiece is uniform and stable, and the compression effect is good. Through the special structural setting, the coaxiality of the workpiece can also be guaranteed to avoid damage to the cylindrical surface of the workpiece. The combined stamping and riveting device described in the present invention is suitable for riveting small-sized thin plate workpieces, and can ensure that the riveted parts are reliably compressed, the coaxiality size is high in precision, and the end faces are well fitted.

[0004] The fully automatic riveting device in the prior art still has some shortcomings during use. The built-in riveting rotor of the riveting device can only rivet the rivets and the workpieces during the descending process. After completing the riveting work, the riveting device will drive the riveting rotor upward. When the next group of workpieces and rivets are sent to the bottom of the riveting rotor, the riveting rotor is driven downward again to rivet the workpieces, driving the riveting rotor upward. During this process, the output power of the entire riveting device remains unchanged, thereby reducing the effective utilization rate of the riveting device, which is inconsistent with the current energy-saving and emission reduction policies. In addition, since the entire equipment does not work during the period when the riveting rotor ascends, the working efficiency of the riveting device is reduced.

[0005] Based on this, the present invention designs a fully automatic riveting device and a riveting process thereof to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to solve the problems that the fully automatic riveting device in the prior art still has some shortcomings during use.

During this process, the output power of the entire riveting device remains unchanged, thereby reducing the effective utilization rate of the riveting device, which is inconsistent with the current energy conservation and emission reduction policies.

At the same time, the control personnel are required to control the auxiliary hydraulic cylinder 4 to perform retraction movement by operating the control cabinet on the rear machine base 2 until the second feeding component 11 descends to the range of the main hydraulic cylinder 4 for the return movement.

[0052] Specifically, the bidirectional riveting assembly 5 includes a first riveting rotary head 501, the top of which is fixedly mounted on the power output end of the power unit module 3, the outer surface of the first riveting rotary head 501 is rotatably connected with a bridge adapter 502, and the top of the bridge adapter 502 is fixedly connected to the bottom of the fuselage of the power unit module 3 through a bridge connecting frame;

[0053] The interior of the bridge-type connecting seat is rotatably connected to the second riveting rotary head 503 via a bearing, and the outer surface of the second riveting rotary head 503 is sleeved with a driven wheel 504. The wheel surface of the driven wheel 504 is transmission-connected to the wheel surface of the driving wheel 506 via a transmission belt 505, and the driving wheel 506 is fixedly sleeved on the outer surface of the first riveting rotary head 501.

[0054] The specific implementation method is: control the operation of the power unit module 3. During the operation, the power unit module 3 will drive the first riveting rotor 501 to rotate rapidly directly above the first loading component 7. The rotation of the first riveting rotor 501 will exert torque on the second riveting rotor 503 through the linkage effect among the driving wheel 506, the transmission belt 505 and the driven wheel 504, thereby driving the second riveting rotor 503 to rotate rapidly directly below the second loading component 11.

[0055] Specifically, the first loading component 7 and the second loading component 11 have the same structure. The first loading component 7 includes a loading box 701, and multiple workpieces 702 are evenly arranged inside the loading box 701. Riveting ports 703 are provided at the top and bottom of the loading box 701 corresponding to the rivet holes on the surfaces of the workpieces 702. A rivet box 704 is fixedly connected to the bottom of the loading box 701 corresponding to the rivet ports 703. Riveting nails 705 are embedded in the rivet boxes 704, and the rivet nails 705 are embedded in the rivet holes.

[0056] The specific implementation method is as follows: the workpiece 702 is conveyed in the loading box 701, the rivet nails 705 are conveyed in the rivet box 704, and after the first riveting rotary head 501 completes the riveting work on the workpiece 702 directly below, the workpiece 702 with the rivet nails 705 continues to be filled into the first loading assembly 7.

[0057] Specifically, the travel connection port 8 is opened at the top of the loading box 701, and the clamping assembly 9 includes a clamping plate 901, which is embedded in the travel connection port 8. The front end face and the rear end face of the clamping plate 901 are fixedly connected with a transfer shaft 902 for transfer.

The bottom of the fixed seat 904 is fixedly connected to the top of the riveting box 704.

[0058] The specific implementation method is as follows: after the first riveting rotary head 501 completes the riveting work on the workpiece 702 directly below, the workpiece 702 equipped with the rivet nails 705 continues to be filled into the first loading assembly 7. At this time, the pressure on the clamping plate 901 increases. Under the action of the pressure, the clamping plate 901 is flipped through the adapter shaft 902, so that the riveted workpiece 702 is transmitted in the direction of the first discharge port 6. After the workpiece 702 is sent out, the clamping plate 901 performs a reset movement under the action of the reset elastic force of the support spring 903. The reset clamping plate 901 continues to clamp and fix the subsequent workpiece 702.

[0059] Specifically, the bottom of the magnetic strip 12 is arranged on the top of the built-in riveting box 704 of the second feeding assembly 11, and the magnetic strip 12 is used to absorb and prevent the rivet nail 705 from falling off.

[0060] A fully automatic riveting process, the fully automatic riveting process includes:

[0061] The two clamping plates 901 located on the first loading assembly 7 and the second loading assembly 11 are respectively set to correspond to the positions of the first riveting rotary head 501 and the second riveting rotary head 503, so that the workpiece 702 directly connected to the clamping plates 901 is located directly below the first riveting rotary head 501 or the second riveting rotary head 503;

[0062] First, the power unit module 3 is controlled to operate. During operation, the power unit module 3 drives the first riveting rotary head 501 to rotate rapidly above the first feeding assembly 7. The rotation of the first riveting rotary head 501 exerts a torque on the second riveting rotary head 503 through the linkage effect among the driving wheel 506, the transmission belt 505 and the driven wheel 504, thereby driving the second riveting rotary head 503 to rotate rapidly below the second feeding assembly 11.

[0063] Control the main hydraulic cylinder 4 to retract, and then drive the power unit module 3 to descend, so as to drive the first riveting rotary head 501 to move toward the first feeding assembly 7. At the same time, the control personnel also need to control the auxiliary hydraulic cylinder 4 to retract by operating the control cabinet on the rear machine base 2 until the second feeding assembly 11 descends to the range of the return movement of the main hydraulic cylinder 4;

[0064] After the first riveting rotary head 501 in the fast rotating state passes through the transfer interface located at the top, it directly contacts the riveting nail 705 located directly below. Since the first riveting rotary head 501 is still in a descending state at this time, the top of the riveting nail 705 is evenly turned up under the combined action of the downward pressure and the torsional force;

[0065] After the first riveting rotary head 501 completes the riveting work on the workpiece 702 directly below, the workpiece 702 equipped with the rivet nails 705 continues to be filled into the first feeding assembly 7. At this time, the pressure on the clamping plate 901 increases. Under the action of the pressure, the clamping plate 901 is turned over through the adapter shaft 902, so that the riveted workpiece 702 is conveyed toward the first discharge port 6. After the workpiece 702 is sent out, the clamping plate 901 performs a reset movement under the action of the reset elastic force of the support spring 903. After the reset, the clamping plate 901 continues to clamp and fix the subsequent workpiece 702.

[0066] After the first riveting rotary head 501 completes the riveting operation on the workpiece 702 directly below, the main hydraulic cylinder 4 is controlled to perform a return movement, and at this time, the second riveting rotary head 503 performs a riveting operation on the workpiece 702 and the rivet nail 705 in the second feeding assembly 11 .

[0067] Working principle, when using:

[0068] The two clamping plates 901 located on the first loading assembly 7 and the second loading assembly 11 are respectively set to correspond to the positions of the first riveting rotary head 501 and the second riveting rotary head 503, so that the workpiece 702 directly connected to the clamping plates 901 is located directly below the first riveting rotary head 501 or the second riveting rotary head 503;

[0069] First, the power unit module 3 is controlled to operate. During operation, the power unit module 3 drives the first riveting rotary head 501 to rotate rapidly above the first feeding assembly 7. The rotation of the first riveting rotary head 501 exerts a torque on the second riveting rotary head 503 through the linkage effect among the driving wheel 506, the transmission belt 505 and the driven wheel 504, thereby driving the second riveting rotary head 503 to rotate rapidly below the second feeding assembly 11.

[0070] Control the main hydraulic cylinder 4 to retract, and then drive the power unit module 3 to descend, so as to drive the first riveting rotary head 501 to move toward the first feeding assembly 7. At the same time, the control personnel also need to control the auxiliary hydraulic cylinder 4 to retract by operating the control cabinet on the rear machine base 2 until the second feeding assembly 11 descends to the range of the return movement of the main hydraulic cylinder 4;

[0071] After the first riveting rotary head 501 in the fast rotating state passes through the transfer interface located at the top, it directly contacts the rivet nail 705 located directly below. Since the first riveting rotary head 501 is still in a descending state at this time, under the combined action of downward pressure and torsional force, the top of the rivet nail 705 is evenly flanged to complete the riveting work of the workpiece 702 and the rivet nail 705. The workpiece 702 is transported in the loading box 701, and the rivet nail 705 is transported in the riveting box 704. The restriction of the rivet nail 705 by the riveting box 704 and the restriction of the workpiece 702 by the loading box 701 are effectively guaranteed to ensure the stability of the rivet nail 705 and the workpiece 702 during the transportation process. Assisted by the mutual squeezing effect between the workpieces 702, the stability of the rivet nail 705 during the contact process with the first riveting rotary head 501 is effectively guaranteed. The first feeding component 7 adopts a strip structure. Compared with the turntable feeding mechanism, it requires fewer power components and control units and has better stability.

[0072] After the first riveting rotary head 501 completes the riveting work on the workpiece 702 directly below, the workpiece 702 equipped with the rivet nails 705 continues to be filled into the first feeding assembly 7. At this time, the pressure on the clamping plate 901 increases. Under the action of the pressure, the clamping plate 901 is turned over through the adapter shaft 902, so that the riveted workpiece 702 is conveyed toward the first discharge port 6. After the workpiece 702 is sent out, the clamping plate 901 performs a reset movement under the action of the reset elastic force of the support spring 903. After the reset, the clamping plate 901 continues to clamp and fix the subsequent workpiece 702.

[0073] After the first riveting rotary head 501 completes the riveting work on the workpiece 702 directly below, the main hydraulic cylinder 4 is controlled to make a return movement. At this time, the second riveting rotary head 503 performs riveting processing operations on the workpiece 702 and the rivet nail 705 in the second feeding assembly 11. The riveting device is simple to operate and has a high riveting efficiency, which effectively improves production efficiency and also achieves energy-saving effects to a certain extent.

[0074] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto.

5. A fully automatic riveting device according to claim 4, characterized in that: The bottom of the magnetic strip (12) is arranged on the top of the built-in riveting box (704) of the second loading assembly (11), and the magnetic strip (12) is used to absorb and prevent the riveting nail (705) from falling off.

6. A fully automatic riveting process according to the fully automatic riveting device of claim 5, characterized in that: The fully automatic riveting process includes: The two clamping plates (901) located on the first loading assembly (7) and the second loading assembly (11) are respectively set to correspond to the positions of the first riveting rotary head (501) and the second riveting rotary head (503), so that the workpiece (702) directly connected to the clamping plates (901) is located directly below the first riveting rotary head (501) or the second riveting rotary head (503); First, the power unit module (3) is controlled to operate. During operation, the power unit module (3) drives the first riveting rotary head (501) to rotate rapidly above the first loading assembly (7). The rotation of the first riveting rotary head (501) exerts a torque on the second riveting rotary head (503) through the linkage effect among the driving wheel (506), the transmission belt (505) and the driven wheel (504), thereby driving the second riveting rotary head (503) to rotate rapidly below the second loading assembly (11). The main hydraulic cylinder (4) is controlled to perform a retracting movement, thereby being able to drive the power unit module (3) to descend, driving the first riveting rotary head (501) to move in the direction of the first loading assembly (7). At the same time, the control personnel are required to control the auxiliary hydraulic cylinder to perform a retracting movement by operating the control cabinet on the rear machine base (2) until the second loading assembly (11) descends to within the range of the main hydraulic cylinder (4) for the return movement; After the first riveting rotating head (501) in the fast rotating state passes through the riveting interface (703) located above, it directly contacts the riveting pin (705) located directly below. Since the first riveting rotating head (501) is still in a descending state at this time, the top end of the riveting pin (705) is evenly flanged under the combined action of the downward pressure and the torsional force; After the first riveting rotary head (501) completes the riveting work on the workpiece (702) directly below, the workpiece (702) equipped with the rivet nails (705) continues to be filled into the first feeding assembly (7). At this time, the pressure on the clamping plate (901) increases. Under the action of the pressure, the clamping plate (901) is turned over through the transfer shaft (902), so that the riveted workpiece (702) is conveyed in the direction of the first discharge port (6). After the workpiece (702) is sent out, the clamping plate (901) performs a reset movement under the action of the reset elastic force of the support spring (903). After the reset, the clamping plate (901) continues to clamp and fix the subsequent workpiece (702); After the first riveting rotary head (501) completes the riveting operation on the workpiece (702) directly below, the main hydraulic cylinder (4) is controlled to perform a return movement, and at this time, the second riveting rotary head (503) performs a riveting operation on the workpiece (702) and the rivet pin (705) in the second loading assembly (11).
