Detailed Implementation

[0026] The technical solutions of the present utility model 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 the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0027] like Figure 1-6 As shown, a large flywheel housing can be flipped for quick loading and unloading, including a bracket 1, a rotating shaft 2 is provided on the bracket 1, a flipping frame 3 is installed on the rotating shaft 2, a chassis 4 for fixing a workpiece 5 is provided on the flipping frame 3, and a workpiece locking mechanism 6 and a workpiece support mechanism 7 are provided on the chassis 4.

[0028] Specifically, a motor 8 is mounted on the bracket 1. The output shaft of the motor is connected to a first gear 10, which meshes with a second gear 9. The second gear 9 is fixedly connected to a rotating shaft 2, and both ends of the rotating shaft 2 are rotatably connected to the bracket 1. When the motor is turned on, it drives the rotating shaft 2 to rotate via the first gear 10 and the second gear 9.

[0029] This application is used when loading and unloading large flywheels. The chassis 4 can support the entire workpiece, and the tilting frame 3 can drive the entire chassis 4 and workpiece to tilt. The worker moves the large flywheel onto the workpiece support mechanism 7 and locks it in place with the workpiece locking mechanism. The motor drives the tilting frame 3 to rotate, which in turn drives the chassis 4 and workpiece to tilt until they reach the tooling position. At this point, the workpiece is fixed on the tooling, and subsequent processing can be performed on the workpiece.

[0030] Specifically, the flipping frame 3 includes a connecting part 31 and a supporting part 32. The supporting part 32 forms an angle α with the vertical direction, where 15°≤α≤20°, preferably 17.5°. This angle minimizes the effort required to manually place the workpiece onto the flipping frame. The flipping frame 3 of this application is designed in accordance with ergonomics, allowing workers to easily move workpieces onto the flipping frame 3 without strenuous effort.

[0031] Furthermore, the 7 includes a first left support 61, a first right support 62, a first left connecting rod 63, a first right connecting rod 64, a first left docking rod 65, and a first right docking rod 66. The first left support 61 and the first right support 62 are respectively fixed to the chassis 4. One end of the first left connecting rod 63 is hinged to the first left support 61, and the other end of the first left connecting rod 63 is hinged to the first left docking rod 65. One end of the first right connecting rod 64 is hinged to the first right support 62, and the other end of the first right connecting rod 64 is hinged to the first right docking rod 66. The ends of the first left docking rod 65 and the first right docking rod 66 are hinged together. A first left locking rod 67 is fixed to the end of the first left connecting rod 63 away from the first left support 61, and a first right locking rod 68 is fixed to the end of the first right connecting rod 64 away from the first right support 62. After the workpiece is placed on the chassis 4, the first left locking rod 67 and the first right locking rod 68 can pass through the center hole of the workpiece to lock it. In use, first pull up the first left connecting rod 65 and the first right connecting rod 66. At this time, the workpiece locking mechanism can pass through the center hole of the large flywheel. Then press down the first left connecting rod 65 and the first right connecting rod 66 so that the first left locking rod 67 and the first right locking rod 68 are pressed onto the workpiece to lock it. The workpiece locking mechanism can prevent the workpiece from falling off during the flipping process.

[0032] The workpiece support mechanism 7 includes a first support block 71, a second support block 72, and a third support block 73 fixed on the chassis 4. The first support block 71, the second support block 72, and the third support block 73 are respectively arranged along the outer edge of the workpiece, and the first support block 71, the second support block 72, and the third support block 73 are respectively provided with a first support groove 711, a second support groove 721, and a third support groove 731. After the workpiece is placed, the outer edge of the workpiece can abut against the first support block 71, the second support block 72, and the third support block 73.

[0033] The chassis is equipped with an anti-rotation mechanism 11 to prevent the workpiece from rotating. The anti-rotation mechanism 11 includes a connecting seat 111 and an adjusting bolt 112. The connecting seat 111 is fixed to the chassis, and the adjusting bolt 112 is threadedly connected to the connecting seat 111. By rotating the adjusting bolt 112, the bottom of the adjusting bolt abuts against the workpiece, preventing the workpiece from rotating around the center of the flipping frame during the flipping process.

[0034] The workpiece support mechanism, workpiece locking mechanism and anti-rotation mechanism in this application work together to fix the workpiece on the chassis 4.

[0035] Furthermore, a floating component 12 is also provided on the chassis 4. The floating component 12 includes an upper fixed seat 121, a lower fixed seat 122 and a tension spring 123. The upper fixed seat 121 is fixed to the lower end of the chassis 4, and the lower fixed seat 122 is fixed to the lower end of the tilting frame 3. The upper fixed seat 121 and the lower fixed seat 122 are connected by a tension spring.

[0036] A positioning rod 13, which is a stepped rod, is vertically mounted on the tilting frame 3. A through hole 15 is provided on the chassis 4. The diameter of the through hole 15 is larger than the diameter of the small end of the positioning rod 13 but smaller than the diameter of the large end of the positioning rod 13. The small end of the positioning rod 13 passes through the through hole 15. Since one end of the tension spring is connected to the chassis 4 that carries the workpiece and the other end of the tension spring is connected to the tilting frame 3, the workpiece can be suspended due to the presence of the tension spring.

[0037] Furthermore, a support rod 14 is fixed on the flipping frame 3 and above the positioning rod 13.

[0038] In order to achieve height adjustment of the floating component 12 to meet the needs of using workpieces of different sizes, in this application, the lower fixed seat 122 is provided with a waist-shaped hole 1221 in the vertical direction, and the lower end of the flipping frame 3 is provided with a bolt hole, and bolts are installed in the waist-shaped hole and the bolt hole.

[0039] The working principle of this utility model is as follows:

[0040] 1. The workpiece is moved onto the chassis and fixed by the workpiece locking mechanism, workpiece support mechanism and anti-rotation mechanism;

[0041] 2. Start the motor. The motor outputs high torque through the first gear and the second gear and transmits it to the tilting frame, thereby realizing the rotation of the tilting frame;

[0042] The rotating frame drives the chassis and workpiece to rotate, causing the workpiece to rotate 90 degrees and move to the tooling position.

[0043] 3. Due to the floating component, the workpiece is in a floating state after flipping, allowing for manual fine-tuning (of the workpiece's vertical, horizontal, and vertical positions). This facilitates faster and easier installation of the workpiece onto the machining fixture 16 for subsequent processing. Then, the motor drives the flipping frame to reset, awaiting the fixing and flipping of the next workpiece.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
