Description

Technical Field

[0001] This application relates to the field of riveting devices, and particularly to riveting devices for sand-proof equipment. Background Technology

[0002] Patent CN118145005A, "A Helicopter Sand Control Air Intake Device," discloses a sand control device comprising a sand control panel, a first air intake, and a sand and dust separation component disposed at the first air intake. The sand and dust separation component includes an air intake pipe connected to the first air intake. The air intake pipe and the sand control panel can be connected by rivets and a riveting device.

[0003] In the existing technology, the riveting head is directly connected to the heating equipment. However, due to the large number of first air inlets on the sandproof panel and the large number of air inlets to be connected to the sandproof panel, the riveting device will generate a large temperature rise during long-term connection operations, which will affect the service life of the riveting device.

[0004] Therefore, it is necessary to propose a riveting device for sand control equipment and extend the service life of the riveting device, which has become an important technical problem that urgently needs to be solved. Utility Model Content

[0005] This application provides a riveting device for sand-proof equipment, which aims to solve the problem in the prior art that the riveting device will generate a large temperature rise during long-term connection operations, thus affecting the service life of the riveting device.

[0006] To achieve the above objectives, this application proposes a riveting device for sand control equipment, including a base, a support frame on the base, a riveting drive mounted on the support frame, and an output end for the riveting drive. The device also includes: a connector connected to the output end; a rotating arm, one end of which is rotatably connected to the connector; and a riveting head connected to the other end of the rotating arm.

[0007] In some embodiments, the device further includes a locking nut, wherein the rotating arm has a through hole for the connector to pass through, and the portion of the connector extending out of the rotating arm is connected to the locking nut.

[0008] In some embodiments, the device further includes a first heat insulation element, wherein the first heat insulation element is disposed between the locking nut and the rotating arm.

[0009] In some embodiments, it further includes: a bearing support, which is disposed at one end of the rotating arm, and the rotating arm is rotatably connected via the bearing support; and a second heat insulation member, which is disposed between the bearing support and the output end.

[0010] In some embodiments, it further includes: a first reduced diameter section, the other end of the rotating arm is connected to the first reduced diameter section, and the riveting head is connected to the rotating arm through the first reduced diameter section.

[0011] In some embodiments, it further includes: an identifier, wherein an identifier is provided on the output terminal.

[0012] This application proposes a riveting device for sand-proof equipment, including a base, a support frame mounted on the base, a riveting drive mounted on the support frame, and an output end for the riveting drive. It also includes: a connector connected to the output end; a rotating arm, one end of which is rotatably connected to the connector; and a riveting head, the other end of which is connected to the riveting head. A heating sleeve is fitted over the outside of the riveting head. The riveting drive presses down on its output end, thereby pressing down the rotating arm and the riveting head. The heating sleeve is heated by pulsed current or other heating methods, which in turn heats the riveting head. The high-temperature riveting head presses against the rivet, deforming it. The rivet is then held under pressure and cooled to form an anchor end, connecting the first air inlet of the sand-proof panel to the air inlet pipe. During the heating process, the rotating arm and connector effectively increase the heat transfer path, preventing continuous heat transfer to the riveting drive, reducing the temperature rise of the riveting drive, and extending the service life of the riveting device.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0016] See Figure 1 and Figure 2 As shown, this application proposes a riveting device for sand control equipment, including a base 1, a support frame 3 on the base 1, a riveting drive 4 installed on the support frame 3, and an output end 2. It also includes: a connector connected to the output end 2; a rotating arm 7, one end of which is rotatably connected to the connector; and a riveting head 10, the other end of which is connected to the riveting head 10.

[0017] The base 1 serves as the structural foundation for the riveting device of the sand control equipment. All other structures on the riveting device are mounted on or indirectly to the base 1. The support frame 3 is the mounting base for the riveting drive 4. The support frame 3 is integrally formed with the base 1, and the riveting drive 4 is detachably mounted on the support frame 3 using screws or other fasteners. The riveting drive 4 is a cylinder containing a movable piston connected to the output end 2. The riveting drive 4 has an air port 11. Pressure changes caused by inflation or deflation move the piston, thereby driving the output end 2 downwards to complete the riveting operation.

[0018] The air intake pipe is made of plastic, the sandproof panel is made of titanium alloy, the air intake pipe is equipped with plastic rivets, and the sandproof panel is equipped with rivet holes around the first air intake hole to match the rivets. The rivets and rivet holes are connected by a riveting device.

[0019] The connector includes a connecting post 16 and a connecting disc, which are welded together to form the connector. The connecting disc is connected to the output end 2 of the riveting drive 4 by fasteners such as screws. The connecting post 16 is used to connect the rotating arm 7.

[0020] The rotating arm 7 and the rivet head 10 mounted on the rotating arm 7 are the core structures of the riveting device for the sand-proof equipment. The rotating arm 7 is rotatably mounted on the connecting column 16. Under the action of the riveting drive 4, the rotating arm 7 can drive the rivet head 10 to move downward. A heating sleeve is fitted on the outside of the rivet head 10. The heating sleeve is heated by pulse current heating (EHOT) or other heating methods. The high-temperature rivet head 10 presses against the rivet column, deforming the rivet column. Then, it is held under pressure and cooled to form an anchor end, thus achieving the connection between the rivet column and the rivet hole. The above riveting operation can also be performed without heating equipment, achieving the connection between the rivet column and the rivet hole simply by cold pressing with the rivet head 10. No specific limitations are made here.

[0021] Specifically, a heating sleeve is fitted onto the outside of the riveting head 10. The riveting drive 4 drives the output end 2 to press down, thereby driving the rotating arm 7 and the riveting head 10 to press down. The heating sleeve is heated by pulse current heating or other heating methods. The heating sleeve heats the riveting head 10, and the high-temperature riveting head 10 presses against the rivet post, deforming the rivet post. It is then held under pressure and cooled to form an anchor end, thus connecting the first air inlet of the sandproof panel to the air inlet pipe. During the above heating process, the arrangement of the rotating arm 7 and the connecting parts can effectively increase the heat transfer path, effectively avoid the continuous transfer of heat to the riveting drive 4, reduce the temperature rise of the riveting drive 4, and extend the service life of the riveting device.

[0022] Among them, since the cross-sectional area of ​​the sandproof panel is large and the first air inlet is evenly distributed on the sandproof panel, the setting of the rotating arm 7 can also effectively lengthen the distance between the riveting head 10 and the support frame 3, so as to avoid interference between the sandproof panel and the support frame 3 during the riveting process.

[0023] The riveting drive 4 is equipped with a control knob, which has a control handle 5. When the operator rotates the control knob to the "start" position, the internal electrical contacts of the knob close, connecting the low-voltage control circuit. This electrical signal drives the intermediate relay to activate its contacts, thereby powering the coil of the higher-power solenoid valve. The energized solenoid valve coil generates a magnetic field, driving the internal valve core to move and switching the compressed air flow path. This directs the processed clean compressed air from the air source to the rodless chamber of the riveting drive 4, while simultaneously allowing the air in the rod chamber of the riveting drive 4 to be discharged through the exhaust port 11 of the solenoid valve. Under the pressure difference, the riveting drive 4 pushes the output end 2 to extend, completing the start-up process. When the control knob is reset to the "closed" position by the control handle 5, the circuit is disconnected, the solenoid valve is de-energized and reset under spring action, the air path is reversed, and the riveting drive 4 retracts in the reverse direction.

[0024] See Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, it further includes: a locking nut 15, the rotating arm 7 having a through hole for the connector to pass through, and the portion of the connector extending out of the rotating arm 7 being connected to the locking nut 15. A connecting post 16 of the connector passes through the rotating arm 7, and the portion of the connecting post 16 passing through the rotating arm 7 has a threaded end, the threaded section being screwed onto the locking nut 15, the nut abutting against the rotating arm 7 to prevent the rotating arm 7 from falling off the connecting post 16.

[0025] See Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, a first heat insulation member 14 is further included, which is disposed between the locking nut 15 and the rotating arm 7. The first heat insulation member 14 is made of aerogel or ceramic material. The first heat insulation member 14 can effectively prevent heat from being transferred from the rotating arm 7 to the locking nut 15, and then from the locking nut 15 to the riveting drive 4, thereby reducing the temperature rise generated by the riveting drive 4.

[0026] See Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the device further includes: a bearing support 13, which is disposed at one end of the rotating arm 7, and the rotating arm 7 is rotatably connected to the bearing support 13 via a connecting member; the bearing support 13 is connected to the rotating arm by screws, and the rotating arm 7 is rotatably connected to the bearing on the bearing support 13 via a connecting post 16; and a second heat insulation member 12, which is disposed between the bearing support 13 and the output end 2. The second heat insulation member 12 is made of aerogel or ceramic material.

[0027] In this embodiment, the rotation of the rotating arm 7 can be locked by tightening the locking nut 15. When in the locked state, the bearing support 13 abuts against the output end 2 through the second heat insulation member 12, and the locking nut 15 abuts against the rotating arm 7 through the second heat insulation member 12, thereby locking the rotation of the rotating arm 7 by friction. When it is necessary to tighten the rotating arm 7, simply loosen the locking nut 15.

[0028] See Figure 1 and Figure 2 As shown, in some embodiments, it further includes: a first reduced diameter portion 8, the other end of the rotating arm 7 is connected to the first reduced diameter portion 8, and the riveting head 10 is connected to the rotating arm 7 through the first reduced diameter portion 8. The provision of the first reduced diameter portion 8 can effectively reduce the dimensional change at the riveting head 10, thereby reducing the impact of stress concentration on the riveting head 10 and the rotating arm 7.

[0029] In this embodiment, a second diameter reduction portion 9 is also provided between the first diameter reduction portion 8 and the riveting head 10, and the outer diameter of the second diameter reduction portion 9 is smaller than the outer diameter of the first diameter reduction portion 8.

[0030] See Figure 1 As shown, in some embodiments, it further includes: a mark 6, which is provided on the output end 2. The mark 6 is used to indicate the extension length of the output end 2, so as to prevent the rivet head 10 from excessively pressing the sandproof panel.

[0031] The above description is only a part or preferred embodiment of this application. Neither the text nor the drawings should limit the scope of protection of this application. All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
