Description

Technical Field

[0001] The invention belongs to the technical field of riveting equipment, and in particular relates to a ventilation valve angle code riveting device. Background Art

[0002] The ventilation valve angle bracket is a kind of connector used in the ventilation system, usually installed at the corners of the ventilation duct to support and connect the duct and ensure the normal operation of the ventilation system. As a connector, it is used to support and connect the corner part of the ventilation duct to ensure the stability and firmness of the duct, and its design can help guide the airflow in the ventilation system so that it flows smoothly, reducing resistance and pressure loss. The ventilation valve angle bracket can also protect the duct to prevent it from being damaged by external impact or extrusion during operation. The ventilation valve angle bracket is usually made of metal materials, such as galvanized steel plates, stainless steel, etc., with strong corrosion resistance and pressure resistance, suitable for use under various environmental conditions. Some angle brackets are also made of plastic materials, mainly used for light ventilation systems or special occasions. The installation of the ventilation valve angle bracket usually requires the use of bolts or welding to fix it at the corner of the ventilation duct. When installing the angle bracket, it is necessary to ensure that it maintains a good connection with the duct and does not affect the normal operation of the ventilation system.

[0003] The corner code riveting device can rivet the ventilation valve all around to keep it firm and stable. The existing ventilation valve corner code riveting device cannot perform riveting according to the change of ventilation valve type due to the various processing types of ventilation valves during operation, resulting in certain limitations in the use of the riveting device, thereby reducing the market versatility of the riveting device. At the same time, when riveting the ventilation valve, only one corner can be riveted, and it cannot be automatically converted according to the riveting position. Not only is the processing speed slow, but the ventilation valve needs to be manually lifted up during processing, resulting in repetitive and numerous steps for the riveting device during processing, resulting in a large overall processing time and resource investment, which greatly increases the processing cost. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a ventilation valve angle code riveting device.

[0005] The technical solution adopted to solve the above technical problems is: to provide a ventilation valve angle code riveting device, including a main body, a bottom plate is fixedly connected to the bottom of the main body, a base is fixedly connected to the bottom of the bottom plate, a rectangular opening is opened at the front end of the bottom plate, a lifting mechanism is installed inside the rectangular opening, and a conversion mechanism is installed on the top of the lifting mechanism;

[0006] An operation frame is provided at the front end of the main body, a replacement mechanism is installed inside the operation frame, and a linkage mechanism is installed at the front end of the replacement mechanism;

[0007] A riveting mechanism is installed inside the main body.

[0008] Furthermore, the lifting mechanism includes a first support block fixedly connected to the inside of the front end of the base plate, the front end of the first support block is fixedly connected to the first motor, the output end of the first motor is fixedly connected to the threaded rod, the outside of the threaded rod is rotatably connected to a sliding rod, first sliding grooves are opened on both sides of the rectangular opening, the tops of both ends of the sliding rod are rotatably connected to the first support rod, the middle ends of the two first support rods are rotatably connected to the second support rod, one ends of the two second support rods are rotatably connected to the second support block, the other ends of the two first support rods are rotatably connected to connecting shafts, the top sides of the second support block are fixedly connected to the load-bearing body, the bottom plate is fixedly connected to a support member, the two ends of the sliding rod are slidably connected to the first sliding groove, the other ends of the two second support rods are rotatably connected to the bottom plate, the other ends of the two connecting shafts are rotatably connected to the load-bearing body, and the other end of the threaded rod is rotatably connected to the support member.

[0009] Through the above technical solution, when in use, the operator places the ventilation valve on the lifting mechanism, and uses the lifting mechanism to raise the ventilation valve to a certain height, which reduces the manual labor of picking up the ventilation valve, thereby reducing labor costs and improving work efficiency. Specifically, the first motor at the front end of the first support block is started to drive the threaded rod to rotate, so that the sliding rod can move to the rear end, and with the two first support rods and the two second support rods cross-connected, the two load-bearing bodies on the top of the second support block are lifted upward, so that the ventilation valve can be raised to a certain height together, thereby greatly improving work efficiency and accelerating the production progress of the factory.

[0010] Furthermore, the conversion mechanism includes a second slide groove opened on the opposite side of the two load-bearing bodies, a third support block is fixedly connected between the two load-bearing bodies, the front end of the third support block is fixedly connected to the first hydraulic cylinder, the piston end of the first hydraulic cylinder is fixedly connected to the support plate, the center of the support plate is rotatably connected to a rotating shaft, the top of the rotating shaft is fixedly connected to a placement plate, the bottom of the rotating shaft is fixedly connected to a one-way gear, one of the load-bearing bodies is fixedly connected to a connecting seat, the inside of the connecting seat is rotatably connected to a clamping strip, both sides of the support plate are respectively slidably connected to the corresponding second slide grooves, the placement plate is located above the two load-bearing bodies, and the one-way gear is meshed with the clamping strip.

[0011] Through the above technical scheme, when in use, the ventilation valve is placed on the conversion mechanism, and then it is transported backward. After the first riveting, it is moved backward and the ventilation valve is rotated, so that it can be riveted for the second time. Specifically, the ventilation valve is placed on the placement plate, and then the first hydraulic cylinder at the front end of the third support block is started to push the support plate at the piston end backward. When the support plate moves backward, the clamping strip connected to the connecting seat on the inner side of one of the load-bearing bodies is rotated to slide along with the one-way gear. After the ventilation valve reaches the riveting position, the clamping strip will be close to one of the load-bearing bodies and remain vertical. When the first riveting is completed, the first hydraulic cylinder is started to pull forward until the one-way gear contacts the clamping strip. As the support plate moves forward, the one-way gear will rotate 90° counterclockwise, and then the first hydraulic cylinder pushes backward again to rivet another corner, and repeats in sequence until all the ventilation valve corners are riveted, thereby greatly improving work efficiency.

[0012] Furthermore, the replacement mechanism includes a protective box fixedly connected to the inside of the operating frame, a second motor fixedly connected to the inside of the protective box, a worm fixedly connected to the output end of the second motor, two first rotating columns rotatably connected to the inside of the protective box, the outer walls of the two first rotating columns are fixedly connected to worm wheels, the outer walls of the two worm wheels are fixedly connected to a first connecting body, the other ends of the two first connecting bodies are rotatably connected to a second connecting body, the other ends of the two second connecting bodies are rotatably connected to a rectangular frame, one end of the two rectangular frames are rotatably connected to a first gear, the two rectangular frames are provided with through grooves, the worm is meshed with the two worm wheels, and the other ends of the two rectangular frames are rotatably connected to the front end of the protective box.

[0013] Through the above technical solution, when in use, the ventilation valve can be fixedly riveted, making the riveting process more stable. Specifically, the second motor inside the protective box is started to drive the worm to rotate. When the worm is engaged with the two worm wheels, and the two first connectors are rotatably connected with the two second connectors, the two rectangular frames are driven to converge to the middle, so that the top of the ventilation valve can be stably riveted.

[0014] Furthermore, the linkage mechanism includes two second rotating columns rotatably connected to the front end of the protective box, the tops of the outer walls of the two second rotating columns are fixedly connected to second gears, the bottoms of the outer walls of the two second rotating columns are fixedly connected to arc frames, the two first gears are meshed with corresponding second gears, and the two arc frames are located inside the through groove.

[0015] Through the above technical scheme, when in use, with the cooperation of the replacement mechanism and the linkage mechanism, another type of ventilation valve can be riveted, thereby improving the applicability of the riveting device. Specifically, when riveting another type of ventilation valve, the second motor is started to drive the worm to rotate, and then when the two rectangular frames rotate, since the two first gears are engaged with the corresponding second gears, the two first gears will rotate and drive the corresponding second gears to rotate at the same time, and then the two arc frames will move forward and the two rectangular frames will move backward. At this point, the ventilation valve riveting type can be replaced, thereby improving the applicability of the riveting device.

[0016] Furthermore, the riveting mechanism includes a second hydraulic cylinder fixedly connected to the top of the main body, a piston rod fixedly connected to the bottom of the second hydraulic cylinder, a rivet head fixedly connected to the bottom of the piston rod, two first guide rods fixedly connected between the rivet head and the main body, and two second guide rods fixedly connected between the rivet head and the operating frame.

[0017] Through the above technical solution, during use, when the ventilation valve is placed in the corresponding position, it is riveted using a riveting mechanism, thereby ensuring the basic function of the riveting device. Specifically, the second hydraulic cylinder on the top of the main body is started to drive the rivet head on the piston rod to rivet downward along the two first guide rods until it moves downward to the upper surface of the protective box along the two second guide rods, completing one riveting, thereby ensuring the basic function of the riveting device.

[0018] The beneficial effects of the present invention are as follows: (1) By designing a lifting mechanism, a conversion mechanism, a replacement mechanism, a linkage mechanism and a riveting mechanism, the present invention can replace various types of ventilation valves when riveting the ventilation valves with angle codes, so that the riveting device has a larger range of use, and the riveting position of the ventilation valve can be replaced when riveting, thereby increasing the riveting speed and greatly improving the work efficiency; (2) By designing a lifting mechanism and a conversion mechanism, the present invention can allow the operator to place the ventilation valve when riveting, and then automatically rise it, and move it to the riveting position of the riveting device, and after riveting once, it can move backward and turn at the same time, and then rivet, thereby improving the riveting rate; (3) By designing a replacement mechanism and a linkage mechanism, when riveting the ventilation valve, after riveting one type of ventilation valve, it can be converted according to the type of ventilation valve, so that it can be replaced, thereby greatly improving the applicability of the riveting device.

When in use, the operator places the ventilation valve on the lifting mechanism 5, and uses the lifting mechanism 5 to raise the ventilation valve to a certain height, reducing the manual labor of taking the ventilation valve, thereby reducing labor costs and improving work efficiency. Specifically, the first motor 502 at the front end of the first support block 501 is started to drive the threaded rod 503 to rotate, so that the sliding rod 504 can move to the rear end. Under the cross-connection of the two first support rods 506 and the two second support rods 507, the two load-bearing bodies 510 on the top of the second support block 508 are lifted upward, and then the ventilation valve can be raised to a certain height together, thereby greatly improving work efficiency and accelerating the production progress of the factory.

At this point, the ventilation valve riveting type can be replaced, thereby improving the applicability of the riveting device.

[0041] like Figure 3-Figure 4As shown, a riveting mechanism 10 is installed inside the main body 1, and the riveting mechanism 10 includes a second hydraulic cylinder 1001 fixedly connected to the top of the main body 1, a piston rod 1002 fixedly connected to the bottom of the second hydraulic cylinder 1001, a riveting head 1003 fixedly connected to the bottom of the piston rod 1002, two first guide rods 1004 fixedly connected between the riveting head 1003 and the main body 1, and two second guide rods 1005 fixedly connected between the riveting head 1003 and the operating frame 7.

When the support plate 604 moves backward When the first riveting is completed, the first hydraulic cylinder 603 is started to pull forward until the one-way gear 607 contacts the clamping strip 609. As the support plate 604 moves forward, the one-way gear 607 rotates 90° counterclockwise, and then the first hydraulic cylinder 603 pushes backward again to rivet another angle. The two first connecting bodies 806 are connected to the two second connecting bodies 807, thereby driving the two rectangular frames 808 to converge toward the middle. When another type of ventilation valve is riveted, the second motor 802 is started to drive the worm 803 to rotate. Then, when the two rectangular frames 808 rotate, the two first gears 809 are meshed with the corresponding second gears 902, so that the two first gears 809 rotate and the two second gears 902 are meshed. The corresponding second gear 902 is driven to rotate, and then the two arc frames 903 will move forward, and the two rectangular frames 808 will move backward. At this point, the riveting type of the ventilation valve can be replaced. After adjustment, the second hydraulic cylinder 1001 on the top of the main body 1 is started to drive the rivet head 1003 on the piston rod 1002 to rivet downward along the two first guide rods 1004 until the two second guide rods 1005 move downward to the upper surface of the protective box 801, completing one riveting, thereby completing the working process of the entire riveting device.
