Description

Technical Field

[0001] This invention relates to the field of production assembly equipment technology, and in particular to a lifting and tilting device for large-size and high-mass products. Background Technology

[0002] In the production process of industries such as aerospace, there are often large-sized and heavy-weight products that require multiple flipping and hoisting operations during assembly.

[0003] Currently, the common method used in factories is to use large overhead cranes in conjunction with manual labor and specialized tilting hoists for product rotation. During rotation, workers first install the tilting hoist onto the product, then the overhead crane rotates the product to change its orientation. After rotation, it is secured using a different type of support for continued assembly. Furthermore, when large, heavy parts need to be joined with other components, overhead cranes and other specialized lifting equipment are still required. These operations involve a significant workload for personnel, are time-consuming, and consume considerable overhead crane operating time, thus consuming factory overhead crane resources. Moreover, the product's rotation posture is limited to a few fixed positions, failing to meet the comfort requirements of assembly workers. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a lifting and flipping device for large-size and high-mass products. The device has rotation, lifting, and flipping functions, enabling the adjustment of the product's posture in lifting, flipping, and other directions, improving the efficiency of personnel assembly operations, enhancing personnel comfort, and featuring easy clamping and rapid operation.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A lifting and flipping device for large-size and high-quality products includes a product fixture for mounting the product. The product fixture is clamped by clamping and locking mechanisms on both sides. The clamping and locking mechanisms are connected to a flipping mechanism, which flips the product. The flipping mechanism is mounted on a lifting mechanism and moves up and down. The lifting mechanism is mounted on a rotating mechanism and rotates the entire device to adjust the product's posture.

[0007] Furthermore, the rotating mechanism includes a mounting base plate, a slewing bearing base, a first slewing bearing, a first reducer, and a first drive motor. The first slewing bearing is mounted on the slewing bearing base, and the first drive motor drives the first reducer to drive the first slewing bearing to rotate. The slewing bearing base is fixed to the ground by the base plate.

[0008] Furthermore, the lifting mechanism includes a lifting column, on which a trapezoidal lead screw assembly, a linear guide rail, a second reducer, a second drive motor, and a lifting slide are mounted. The lifting column is mounted on a rotating mechanism. The lifting slide is connected to the trapezoidal lead screw assembly. The trapezoidal lead screw assembly is connected to the second drive motor via the second reducer. The second drive motor drives the second reducer to rotate, which in turn drives the trapezoidal lead screw in the trapezoidal lead screw assembly to rotate, causing the lifting slide to move up and down along the linear guide rail.

[0009] Furthermore, buffer modules and safety limit sensors are installed at both ends of the linear guide rail.

[0010] Furthermore, the lifting slide includes a slide body, a lead screw nut, and a linear guide slider. The slide body is slidably connected to the linear guide through the linear guide slider, and the lead screw nut cooperates with the trapezoidal lead screw assembly to achieve self-locking. The connection surface between the lifting slide body and the mounting tilting mechanism is provided with threaded holes and positioning stops for mounting the tilting mechanism.

[0011] Furthermore, the tilting mechanism includes a base plate, a second slewing bearing, a third reducer, and a third drive motor. The second slewing bearing, the third reducer, and the third drive motor are all mounted on the base plate. The third drive motor is connected to the second slewing bearing through the third reducer, and the third drive motor drives the third reducer to drive the second slewing bearing to rotate. The base plate is mounted on the lifting mechanism.

[0012] Furthermore, the locking and clamping mechanism includes a trunnion mounting base, a trunnion mounting cover, a rotating shaft, a push rod, a push rod motor, and a locking mechanism. The end of the trunnion mounting cover is rotatably connected to the end of the trunnion mounting base via the rotating shaft. The push rod and push rod motor are installed on the lower side of the trunnion mounting base. An arm extends from the end of the trunnion mounting cover near the rotating shaft, and a pin hole is provided at the end of the arm. The push rod is connected to the trunnion mounting cover through the pin hole. When the push rod motor rotates, it drives the push rod to extend and retract, thereby causing the trunnion mounting cover to rotate around the rotating shaft. The locking mechanism is installed on the end of the trunnion mounting base away from the rotating shaft. When the trunnion mounting cover and the trunnion mounting base are closed, the trunnion mounting cover and the trunnion mounting base are locked together.

[0013] Furthermore, the trunnion mounting base includes a fixedly connected vertical plate and a horizontal plate. The vertical plate is connected to a flipping mechanism. The horizontal plate is designed with two semi-cylindrical trunnion slots, with a spherical center. The trunnion mounting cover is designed with two semi-cylindrical trunnion slots below, with a spherical center, and their shape and size match the slots on the horizontal plate of the trunnion mounting base. One end of the trunnion mounting cover is provided with a pivot hole, which matches the pivot hole on the trunnion mounting base. The pivot passes through the pivot hole, rotatably connecting the trunnion mounting base and the trunnion mounting cover.

[0014] Furthermore, the locking mechanism includes a flip lock, a lead screw and nut, a linear guide rail and a slider, a fourth reducer, a fourth drive motor, and a limiting mechanism. The flip lock has a U-shaped structure, with its lower part connected to the linear guide rail and slider, which are fixed to the lower side of the trunnion mounting base. A trapezoidal lead screw and nut are connected to the middle position below the flip lock. The flip lock is connected to the trapezoidal lead screw and nut, which are connected to the fourth drive motor via the fourth reducer. The fourth drive motor drives the lead screw of the lead screw and nut to rotate via the fourth reducer, thereby causing the flip lock to move horizontally in a linear motion relative to the trunnion mounting base.

[0015] Furthermore, the product tooling includes a tooling body and trunnions. The shape of the tooling body is consistent with the shape of the product. Trunnions are connected to both sides of the tooling body. The trunnions match the trunnion mounting lower seat and the trunnion mounting upper cover in the locking and clamping mechanism.

[0016] The present invention, by adopting the above-mentioned technical solution, has the following positive effects compared with the prior art:

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] This invention provides a method such as Figure 1 The lifting and tilting device shown is designed for large-size and heavy-weight products and includes: a rotating mechanism 1, a lifting mechanism 2, a tilting mechanism 3, a clamping and locking mechanism 4, and a product fixture 5. The rotating mechanism 1, lifting mechanism 2, tilting mechanism 3, and clamping and locking mechanism 4 can together form a multi-degree-of-freedom attitude adjustment component. For large-size and heavy-weight products, two components move synchronously to form a lifting and tilting device, realizing the connection and clamping of large-size products.

[0029] The rotating mechanism 1 is located at the bottom layer and can drive the entire equipment to rotate, thereby adjusting the product's posture. When the two components move synchronously, the rotating mechanisms on both sides must be aligned and locked in position, and must not rotate. The lifting mechanism 2 can drive the flipping mechanism 3, the clamping and locking mechanism 4, and the product fixture 5 to achieve lifting and lowering movements. The lifting and lowering on both sides can be controlled synchronously, thereby adjusting the height of large-sized products. The flipping mechanism 3 can drive the clamping and locking mechanism 4 and the product fixture 5 to achieve flipping movements. The flipping on both sides can be controlled synchronously, thereby allowing for 360-degree arbitrary adjustment of the angle of large-sized products.

[0030] As attached Figure 2 As shown, the rotating mechanism 1 consists of a mounting base 101, a slewing bearing base 102, a first slewing bearing 103, a first reducer 104, and a first drive motor 105. The first slewing bearing 103 is mounted on the slewing bearing base 102 and is driven by the first drive motor 105, which in turn drives the first reducer 104 to rotate the upper lifting mechanism 2, the tilting mechanism 3, the clamping and locking mechanism 4, the tooling, and the product. The rotating mechanism can be fixed to the ground by the mounting base 101.

[0031] As attached Figure 3 As shown, the lifting mechanism 2 consists of a lifting column 201, a trapezoidal lead screw assembly 202, a linear guide rail 203, a second reducer 204, a second drive motor 205, a buffer module 206, a safety limit sensor 207, and a lifting slide 210. The trapezoidal lead screw assembly 202, linear guide rail 203, second reducer 204, second drive motor 205, buffer module 206, and safety limit sensor 207 are all mounted on the lifting column 201.

[0032] The lifting column 201 can be installed on the first slewing bearing 103 of the rotating mechanism 1.

[0033] As attached Figure 4 As shown, the lifting slide 210 consists of a slide body 211, a lead screw nut 212, a linear guide slider 213, etc. The lifting slide 210 is connected to the lifting mechanism 2 through the lead screw nut 212 and the slider 213.

[0034] The second drive motor 205 in the lifting mechanism 2 drives the second reducer 204 to rotate, which can drive the trapezoidal lead screw in the trapezoidal lead screw assembly 202 to rotate. Through the cooperation with the lead screw nut 212, the lifting slide 210 can move up and down along the linear guide rail 203, thereby driving other components and products to lift.

[0035] The trapezoidal lead screw assembly 202 and the lead screw nut 212 cooperate to achieve self-locking of the mechanical mechanism. When the second drive motor 205 is de-energized, the overall structure will not move downward due to its own gravity, thus having a high degree of safety.

[0036] To prevent danger caused by exceeding movement limits, a set of safety limit sensors 207 and buffer modules 206 are installed at both the upper and lower ends. When the movement reaches the limit position, the safety limit sensor 207 is triggered, which can control the motor to stop. If the electrical system malfunctions, the lifting slide 210 will contact the upper and lower buffer modules 206. The buffer modules can absorb the collision energy of the slide movement and avoid structural damage. The buffer modules 206 can be implemented in various ways, such as using energy-absorbing materials and spring shock absorbers.

[0037] The front of the lifting slide body 211 has a set of threaded holes and a positioning stop, which can be used to install the flipping mechanism 3.

[0038] As attached Figure 5 As shown, the tilting mechanism 3 consists of a base plate 301, a second slewing bearing 302, a third reducer 303, a third drive motor 304, etc. The tilting mechanism 3 can be mounted on the lifting slide body 211 of the lifting mechanism 2 via the base plate 301.

[0039] The second slewing bearing 302, the third reducer 303, and the third drive motor 304 are all mounted on the base plate 301. The third drive motor 304 drives the third reducer 303, and the second slewing bearing 302 can support the clamping and locking mechanism 4, tooling, and products mounted on it to achieve rotation.

[0040] The second slewing bearing 302 adopts worm gear transmission and has self-locking characteristics. When the motor 304 is de-energized, the product and tooling will not move due to their own gravity when flipped to any angle, thus having a high degree of safety.

[0041] The clamping and locking mechanism 4 is a two-part structure that can be opened and closed. It is designed with two cylindrical deep grooves, the ends of which are spherical. These grooves can cooperate with the trunnions on both sides of the product fixture 5. When the trunnions are inserted into the deep grooves, the cover plate on the clamping and locking mechanism 4 is closed, thus restraining the product fixture 5 and the product connected to it, achieving the function of reliably supporting the product. (See attached image) Figure 6 As shown, the locking and clamping mechanism 4 consists of a trunnion mounting base 401, a trunnion mounting cover 402, a rotating shaft 403, a push rod 404, a push rod motor 405, and a locking mechanism 410. The trunnion mounting cover 402, the rotating shaft 403, the push rod 404, the push rod motor 405, and the locking mechanism 410 are all connected to the trunnion mounting base 401. The locking and clamping mechanism 4 can be mounted on the second slewing support 302 of the flipping mechanism 3 via the trunnion mounting base 401.

[0042] The trunnion mounting base 401 is designed in a T-shape. Its vertical plate can be designed with threaded connection holes to connect with the second slewing bearing 302. Its horizontal plate is designed with two semi-cylindrical trunnion slots, and the middle position of the slots is spherical. The horizontal and vertical plates are fixedly connected by welding or other means. One end of its horizontal plate is provided with a shaft hole.

[0043] The trunnion mounting cover 402 has two semi-cylindrical trunnion slots below it. The middle of the slot is spherical, and its shape and size match the slot on the horizontal plate of the trunnion mounting base 401. One end of the slot is provided with a pivot hole, which can be matched with the pivot hole on the base 401.

[0044] The rotating shaft 403 can pass through the rotating shaft hole on the trunnion mounting lower seat 401 and the trunnion mounting upper cover 402 to realize the connection between the two. The trunnion mounting upper cover 402 can rotate relative to the trunnion mounting lower seat 401 around the rotating shaft 403.

[0045] A support arm extends from one side of the trunnion mounting cover 402, and a pin hole is provided at the end of the support arm. A push rod 404 can be connected to the trunnion mounting cover 402 through this pin hole. The push rod 404 can be mounted on a push rod mounting seat below the trunnion mounting base 401 and can rotate around the shaft hole on the push rod mounting seat; a push rod motor 405 can be connected to the push rod 404. The above mechanisms form a linkage-slider mechanism. When the drive motor rotates, it can drive the push rod to extend and retract, thereby pushing the trunnion mounting cover 401 to rotate around the rotating shaft 403.

[0046] The push rod 404 is driven by a worm gear and has a self-locking function. When the push rod motor 405 is de-energized, the trunnion mounting cover 402 will not fall due to its own weight, which can ensure the safety of the mechanism.

[0047] As attached Figure 7 As shown, the locking mechanism 410 consists of a flip lock 411, a lead screw and nut 412, a linear guide rail and slider 413, a fourth reducer 414, a fourth drive motor 415, and a limiting mechanism 416. All of the above mechanisms are installed at one end of the lower side of the trunnion mounting base 401.

[0048] The flip lock 411 has a U-shaped structure, with its lower part connected to a linear guide rail and a slider 413. It can move horizontally along the guide rail relative to the trunnion mounting base 401. A trapezoidal lead screw and a nut 412 are connected to the middle position of the lower part of the flip lock 411. The fourth drive motor 415 drives the lead screw to rotate through the fourth reducer 414, and then the horizontal movement of the flip lock 411 is realized through the cooperation of the lead screw and nut. The limiting mechanism 416 is a long rod type, with one end fixed to the lower base 401. It can pass through the long slot hole below the flip lock 411 to prevent the flip lock 411 from moving beyond the limit.

[0049] The trapezoidal lead screw and nut 412 have self-locking characteristics. When the motor 415 is powered off, it can remain self-locked and will not move due to force or other circumstances, thus ensuring the safety of the lock.

[0050] As shown in Figure 8(a), this state is the fully open state of the locking and clamping mechanism 4. In this state, the upper cover 402 can be opened at an angle greater than 90°, which can completely clear the space above the trunnion mounting base 401, making it convenient for the product tooling 5 to dock and cooperate with the locking and clamping mechanism 4.

[0051] As shown in Figure 8(b), when the trunnion mounting cover 402 is rotated to the closed state, the locking mechanism 410 can move inward linearly under the drive of the motor, locking the trunnion mounting cover 402 and the trunnion mounting base 401 together. In this state, the locking clamping mechanism 4 can firmly clamp the trunnion of the product tooling 5, locking the locking clamping mechanism 4, the product tooling 5 and the product into a whole, which can firmly clamp the product during the 360° rotation process.

[0052] The flipping clamping mechanism 4 can also be equipped with sensors for closing and locking in place. Flipping is only allowed when both the closing and locking positions are in place, thus achieving electrical safety interlocking, ensuring operational safety, and preventing misoperation.

[0053] As attached Figure 9 As shown, the product fixture 5 mainly consists of a fixture body 501 and trunnions 502. The fixture body 501 can be designed according to the actual shape of the product and matches the connection position of the product. It can cooperate with the clamping and locking mechanism 4 to fix the product to the lifting and flipping device. The fixture body 501 has connecting holes on its side for connecting the trunnions 502. Two holes are provided on each side to connect two trunnions 502. The trunnion 502 consists of three parts: a ball section 5021, a cylindrical section 5022, and a threaded section 5023. The trunnion can be fixed to the fixture body by threads or other means. The shape of the trunnion 502 matches the shape and size of the trunnion groove in the trunnion mounting lower seat 401 and the trunnion mounting upper cover 402 in the locking and clamping mechanism 4, and can be embedded therein. The ball section is used for positioning to prevent the fixture from moving left and right in the locking and clamping mechanism 4. The two sets of trunnions cooperate with the locking and clamping mechanism 4 to achieve complete constraint on the fixture and the product, ensuring its clamping stability.

[0054] Since each side of the product tooling 5 has two trunnions, the clamping mechanism can still carry the tooling and product through the trunnions when it is in the open state. In this state, the equipment has a floating support function, which can be used to dock the product with other parts or place it on other platforms to avoid over-constraint during the docking process and effectively protect the product and equipment.

[0055] In summary, this equipment has rotation, lifting, and flipping functions, enabling the adjustment of the product's posture in lifting, flipping, and other directions. It is designed with product tooling with trunnions and corresponding clamping mechanisms, which can realize the rapid positioning of the product tooling assembly with the equipment. This equipment can improve the efficiency of personnel assembly operations, improve personnel comfort, and has the characteristics of easy clamping and rapid operation.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
