Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting technology, specifically a balanced hoisting fixture for assembling large-scale components. Background Technology
[0002] In the assembly of large-scale composite material components, specially designed lifting fixtures must be used to ensure the safe and stable lifting and handling of the workpieces. These lifting fixtures can be precisely adapted to the shape, size, and weight of the workpieces, thereby effectively distributing stress during the lifting process and preventing deformation or damage to the workpieces due to uneven stress.
[0003] In the prior art, patent announcement number CN222348469U discloses an adjustable-angle lifting beam and lifting fixture, comprising: a beam body; multiple first lifting lugs disposed on one side of the beam body; and multiple second lifting lugs disposed on the side of the beam body opposite to the first lifting lugs; each second lifting lug includes a first sub-lifting lug and a second sub-lifting lug, the first sub-lifting lug extending along the length of the beam body and the second sub-lifting lug extending along the width of the beam body. This embodiment provides a lifting beam capable of angle adjustment, with different lifting lugs disposed on both sides of the angle-adjustable lifting beam.
[0004] Due to the wide variety of specifications and relatively large mass of composite material components, instability often occurs during hoisting operations due to variations in size and uneven weight distribution. This not only increases the difficulty of hoisting operations but also potentially raises safety risks. Therefore, a balanced lifting fixture for assembling large-sized components is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a balanced lifting fixture for assembling large-sized components, so as to solve the problems in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a balancing lifting fixture for assembling large-sized components, including a hook, a fixture frame connected to the hook, an end panel fixedly installed on one side of the fixture frame, a cylinder fixedly installed on one side of the end panel, a leveling mechanism installed on the fixture frame, the leveling mechanism including a positioning screw fixedly installed on the fixture frame and a servo motor fixedly installed on the other side of the fixture frame, an adjusting screw fixedly installed at the output end of the servo motor, a screw slider threaded onto the adjusting screw and slidably installed on the fixture frame, a gyroscope fixedly installed on the fixture frame, and a clamping mechanism fixedly installed on the side wall of the end panel.
[0007] Preferably, the leveling mechanism further includes a counterweight connected to the positioning screw, a locking nut threaded onto the positioning screw, and a lifting ring fixedly mounted on the lead screw slider.
[0008] Preferably, a bearing is installed on the tooling frame, and the adjusting screw is rotatably mounted on the tooling frame via the bearing.
[0009] Preferably, a coupling is installed at the output end of the servo motor, the adjusting screw is fixedly installed at the output end of the servo motor through the coupling, the counterweight is restricted to the positioning screw by a locking nut, and the hook is connected to the screw slider through a lifting ring.
[0010] Preferably, the clamping mechanism includes a lower clamp fixedly mounted on the end panel and an electric push rod. A connecting rod is movably mounted on the lower clamp. An upper clamp is fixedly mounted on the upper end of the connecting rod. A return spring is sleeved on the connecting rod. A spring seat is fixedly mounted on the connecting rod. The lower end of the connecting rod is fixedly mounted on the pressure beam. A wedge block is fixedly mounted on the output end of the electric push rod.
[0011] Preferably, the lower clamp has a movable hole, and the connecting rod is movably mounted on the lower clamp through the movable hole.
[0012] Preferably, the upper clamp is movably mounted above the lower clamp via a connecting rod, one end of the return spring is fixedly connected to the spring seat, the other end of the return spring is fixedly mounted on the lower clamp, and the wedge block is movably mounted below the pressure beam via an electric push rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. In this application, when the tooling frame is not in a horizontal state, the servo motor can be started. After the servo motor is started, it will drive the adjusting screw to rotate. When the adjusting screw rotates, it will drive the screw slider to slide on the tooling frame, thereby adjusting the lifting position of the lifting ring, so that the tooling frame reaches a horizontal state and ensures the stability of the lifting posture.
[0015] 2. In this application, when the electric push rod extends, it drives the wedge block to move forward, which forces the pressure beam to move downward. As the pressure beam moves downward, it drives the connecting rod to move downward synchronously. This downward movement of the connecting rod, in turn, drives the upper clamp to move downward, thereby clamping the cylinder and facilitating hoisting operations. After the cylinder is hoisted to the installation position, the electric push rod can be retracted. When the electric push rod retracts, the wedge block moves away from the pressure beam. After the wedge block moves away, the return spring pulls the connecting rod upward, releasing the upper clamp and facilitating the unloading of the cylinder. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a balanced lifting fixture for assembling large-sized components, including a hook 4, a fixture frame 1 connected to the hook 4, an end panel 2 fixedly installed on one side of the fixture frame 1, a cylinder 3 fixedly installed on one side of the end panel 2, a leveling mechanism 5 installed on the fixture frame 1, and a clamping mechanism 6 fixedly installed on the side wall of the end panel 2. The clamping mechanism 6 can fix the workpiece on the fixture frame 1, and the leveling mechanism 5 can adjust the posture of the fixture frame 1 to ensure the stability of the lifting posture.
[0023] like Figure 2 and Figure 3As shown, the leveling mechanism 5 includes a positioning screw 505 fixedly installed on the tooling frame 1 and a servo motor 501 fixedly installed on the other side of the tooling frame 1. An adjusting screw 502 is fixedly installed at the output end of the servo motor 501. A screw slider 503 is threadedly installed on the adjusting screw 502 and is slidably installed on the tooling frame 1. A gyroscope 508 is fixedly installed on the tooling frame 1. The leveling mechanism 5 also includes a counterweight 507 connected to the positioning screw 505. A locking nut 506 is threadedly installed on the positioning screw 505. A lifting ring 504 is fixedly installed on the screw slider 503. A bearing is installed on the tooling frame 1, and the adjusting screw 502 is rotatably installed on the tooling frame 1 through the bearing.
[0024] Specifically, before the hoisting operation begins, the counterweight 507 can be fixed to the tooling frame 1 by the synergistic action of the positioning screw 505 and the locking nut 506. Simultaneously, the attitude of the tooling frame 1 is detected using a gyroscope 508. When the tooling frame 1 is not horizontal, the servo motor 501 can be activated. After the servo motor 501 is activated, it drives the adjusting screw 502 to rotate. As the adjusting screw 502 rotates, it causes the screw slider 503 to slide on the tooling frame 1, thereby adjusting the hoisting position of the lifting ring 504, bringing the tooling frame 1 to a horizontal position and ensuring the stability of the hoisting posture.
[0025] like Figure 2 and Figure 4 As shown, the clamping mechanism 6 includes a lower clamp 602 and an electric push rod 608 fixedly mounted on the end panel 2. A connecting rod 607 is movably mounted on the lower clamp 602. An upper clamp 601 is fixedly mounted on the upper end of the connecting rod 607. A return spring 603 is sleeved on the connecting rod 607. A spring seat 604 is fixedly mounted on the connecting rod 607. The lower end of the connecting rod 607 is fixedly mounted on the pressure beam 606. A wedge block 605 is fixedly mounted on the output end of the electric push rod 608. A movable hole is provided on the lower clamp 602, and the connecting rod 607 is movably mounted on the lower clamp 602 through the movable hole.
[0026] Specifically, after the electric push rod 608 extends, it drives the wedge block 605 to move forward. The forward displacement of the wedge block 605 forces the pressure beam 606 to move downward. The downward movement of the pressure beam 606 drives the connecting rod 607 to move downward. The downward movement of the connecting rod 607 drives the upper clamp 601 to move downward, thereby clamping the cylinder 3 to facilitate the hoisting operation. After the cylinder 3 is hoisted to the installation position, the electric push rod 608 can be retracted. After the electric push rod 608 retracts, the wedge block 605 moves away from the pressure beam 606. At this time, the return spring 603 pulls the connecting rod 607 upward, causing the upper clamp 601 to release, facilitating the unloading of the cylinder 3.
[0027] Working principle: When in use, first place one end of the cylinder 3 in the clamp. Then, control the electric push rod 608 to extend. After the electric push rod 608 extends, it will drive the wedge block 605 to move forward. After the wedge block 605 moves forward, it will force the pressure beam 606 to move downward. After the pressure beam 606 moves downward, it will drive the connecting rod 607 to move downward. After the connecting rod 607 moves downward, it will drive the upper clamp 601 to move downward, thereby clamping the cylinder 3 for easy hoisting. After the cylinder 3 is hoisted to the installation position, control the electric push rod 608 to retract. After the electric push rod 608 retracts, the wedge block 605 will move away from the pressure beam 606. After the wedge block 605 moves away from the pressure beam 606, the return spring 603 will pull the connecting rod 607 upward, causing the upper clamp 601 to loosen, making it easy to unload the cylinder 3. Before hoisting, the counterweight 507 can be fixed to the tooling frame 1 by the cooperation of the positioning screw 505 and the locking nut 506. The attitude of the tooling frame 1 can be detected by the gyroscope 508. When the tooling frame 1 is not horizontal, the servo motor 501 can be started. After the servo motor 501 is started, it will drive the adjusting screw 502 to rotate. After the adjusting screw 502 rotates, it will drive the screw slider 503 to slide on the tooling frame 1, thereby adjusting the hoisting position of the lifting ring 504 and adjusting the tooling frame 1 to a horizontal state to ensure the stability of the hoisting attitude.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
