[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1

[0023] like Figure 1-3 As shown, the rotating device for stamping the retaining frame cover provided in this embodiment is suitable for the punching processing of extra-large precision retaining frame covers with a diameter of 1000-2000mm, which includes a floating turntable 2, a lifting device 3, and a rotating device 4; the floating turntable 2 is arranged above the rotating device 4 for carrying the retaining frame cover, the lifting device 3 is arranged between the floating turntable 2 and the rotating device 4 for lifting the floating turntable 2, and the rotating device 4 is used to drive the floating turntable 2 and the lifting device 3 to rotate along the horizontal plane.

[0024] The lifting mechanism 3 includes several first cylinders 3.1, which are fixed to the floating turntable 2. The piston rods of the first cylinders 3.1 pass through the floating turntable 2 and are fixed to the rotating mechanism 4. In this example, there are four first cylinders 3.1, evenly distributed at the center of the floating turntable 2. The lifting and lowering motion of the floating turntable 2 relative to the rotating mechanism 4 is achieved through the telescopic movement of the piston rods. (That is, the first cylinders 3.1 drive the floating turntable 2 to reciprocate along the Z-axis.)

[0025] The rotating device 4 includes a motor and a fixed disk 4.2, with the output end of the motor connected to the fixed disk 4.2. The motor in this example is a direct-drive motor 4.1. Specifically, a reducer 4.3 is provided between the direct-drive motor 4.1 and the fixed disk 4.2. The power output end of the direct-drive motor 4.1 is connected to the input end of the reducer 4.3 via a belt. The output end of the reducer 4.3 is connected to the fixed disk 4.2. The fixed disk 4.2 rotates with the output end of the reducer 4.3. The end of the piston rod of the first cylinder 3.1 is fixed to the fixed disk 4.2. It should be noted that the first cylinder 3.1 in this example can also be replaced by a hydraulic cylinder.

[0026] During operation, the direct-drive motor 4.1 rotates the reducer 4.3 via a belt. The reducer 4.3 reduces speed and then rotates the fixed plate 4.2, which in turn rotates the floating turntable 2. The direct-drive motor 4.1 and the reducer cooperate to improve the accuracy of the rotation angle of the floating turntable 2, thereby improving machining accuracy.

[0027] Several guide posts 3.2 are disposed between the floating turntable 2 and the rotating device 4. The top ends of the guide posts 3.2 are mounted on the floating turntable 2, and the bottom ends of the guide posts 3.2 extend through a fixed disk 4.2. The fixed disk 4.2 is provided with guide sleeves 3.3 that match the guide posts 3.2. The guide posts 3.2 and the guide sleeves 3.3 are slidably engaged. In this embodiment, there are four guide posts 3.2, distributed circumferentially. The coordination between the guide posts 3.2 and the guide sleeves 3.3 enables smooth lifting and lowering of the floating turntable 2, thereby improving machining accuracy.

[0028] The floating turntable 2 is provided with a clamping device comprising a plurality of second cylinders 2.1 and a plurality of clamping blocks 2.2. These second cylinders 2.1 are distributed circumferentially around the floating turntable 2, positioned below the latter. The piston rods of these second cylinders 2.1 extend through the floating turntable 2 and connect to the clamping blocks 2.2 above it. It should be noted that the number and position of the clamping devices can be determined based on the prefabricated holes to be machined in the retainer cap. In this embodiment, there are six second cylinders 2.1 and six clamping blocks 2.2, evenly distributed around the circumference of the floating turntable 2.

[0029] Several mold grooves 2.4 are provided on the floating turntable 2. It should be noted that the number and position of the mold grooves 2.4 are matched with the prefabricated holes to be processed in the retaining cover to be processed. In this example, there are six mold grooves 2.4, and each mold groove 2.4 is provided with a clamping device consisting of a second cylinder 2.1 and a clamping block 2.2 on both sides. Providing clamping devices on both sides of the mold groove 2.4 is conducive to ensuring the accuracy during stamping. Locating pins are also provided in the mold. When positioning the retaining cover, radial precision positioning can be performed by utilizing the pre-punched holes on the retaining cover product and the locating pins in the mold. The mold grooves provided on the floating turntable 2 also solve the problem of difficulty in manufacturing large retaining cover molds, and facilitate the stamping process of large retaining cover. It should be noted that the second cylinder 2.1 in this example can also be replaced by a hydraulic cylinder.

[0030] The floating turntable 2 is provided with a plurality of positioning blocks 2.3 that match the stoppers on the cage cover and are used for centering and positioning the cage cover. In this example, the positioning blocks 2.3 are located at the circumference of the floating turntable 2.

[0031] The rotary device for punching retainer covers in this embodiment also includes a moving device 5. The rotary device 4 is mounted on the moving device 5, which is in turn mounted on a frame 6. The moving device 5 is located on the front of the punch press 1 and is used to adjust the horizontal distance between the rotary device 4, the floating turntable 2, and the punch head of the punch press 1 to accommodate retainer covers of varying inner diameters. (That is, the moving device 5 can reciprocate along the Y-axis.) This also facilitates the replacement and installation of the floating turntable 2. The moving device 5 includes at least one linear guide 5.1, a slide 5.2, and an electric push rod 5.3. The slide 5.2 is mounted on the linear guide 5.1 and slidably connected to the linear guide 5.1. The electric push rod 5.3 is connected to the slide 5.2 and is used to drive the slide 5.2 to move along the linear guide 5.1. The rotary device 4 is mounted on the slide 5.2.

[0032] In this example, two linear guides 5.1 are mounted on a frame 6, arranged in parallel. A slide 5.2 is fixedly mounted on the sliders of the two linear guides 5.1. A direct-drive motor 4.1 and a reducer 4.3 are fixedly connected to the slide 5.2 using methods readily achievable by conventional techniques. The direct-drive motor 4.1 is positioned below the slide 5.2, the reducer 4.3's input is positioned below the slide 5.2, and the reducer's output is positioned above the slide 5.2. The housing of an electric push rod 5.3 is fixedly mounted on the frame 6, to one side of the slide 5.2. The push rod 5.3 is arranged parallel to the linear guides 5.1, and its push rod is fixedly connected to the side of the slide 5.2 via a connecting plate.

[0033] The usage of this embodiment:

[0034] ① Place the blank manually or automatically on the floating turntable 2, which has a stopper. The stopper is used to precisely locate the center of the product. Pre-punched holes in the product and locating pins in the mold are then used for radial precision positioning. Once positioning is complete, the clamping mechanism secures the product.

[0035] ②The slider moves downward with the punch to complete the punching of the product hole

[0036] ③ During the return stroke of the slider carrying the punch, the floating turntable 2 rises;

[0037] ④ After the floating turntable 2 is raised to its position, it rotates to a corresponding angle (the HMI can be set according to process requirements);

[0038] ⑤The floating turntable 2 drops again;

[0039] ⑥ Punch press 1 punches again;

[0040] ⑦ Then repeat steps ③ to ⑥ until the holes on the product are punched.

[0041] ⑧Take out the product, put in the next blank, and repeat the next process.

[0042] The beneficial effects of this embodiment compared with the prior art are:

[0043] 1. The floating turntable 2 is used to carry large cage covers, solving the problem of the workbench being unable to support the cage cover and thus being unable to stamp when the cage cover is much larger than the workbench size.

[0044] 2. The large retainer cover is punched by setting the lifting device 3 and the rotating device 4 in conjunction with the punch of the punch press 1.

[0045] 3. By setting the moving device 5, the horizontal distance between the rotating device 4 and the floating turntable 2 and the punch of the punch press 1 can be adjusted to adapt to the stamping processing of retainer covers with different inner diameters.

[0046] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
