Description

Technical Field

[0001] This utility model relates to the technical field of sheet metal processing equipment, specifically a sheet metal rotating device for edge grinding. Background Technology

[0002] After slitting and other processes, sheet metal generally requires edge grinding. This grinding process involves rotating and changing the edges of the sheet metal using a rotating device for continuous edge grinding. Currently, the rotating device on production lines is typically used in conjunction with a conveyor mechanism. In this system, the conveyor transports the sheet metal to the rotating device, where a robotic arm above it grips, lifts, and rotates the sheet metal using suction cups or similar methods. However, this structure lacks sufficient stability in gripping the sheet metal, making it prone to wobbling and loosening. Insufficient rotational stability also leads to incomplete rotation, affecting the accuracy of subsequent edge grinding. Utility Model Content

[0003] The purpose of this invention is to provide a plate rotation device for edge grinding, which addresses the problem that existing plate rotation devices lack sufficient gripping stability, causing the plate to wobble and loosen, resulting in insufficient rotation stability and incomplete rotation, thus affecting the positional accuracy of subsequent edge grinding.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a plate rotation device for edge grinding, comprising:

[0005] feeding table;

[0006] The lower turntable has a bottom that connects to a lifting shaft. The lifting shaft passes through the top surface of the feeding table and extends into the inner cavity of the feeding table. It is coaxially connected to the output shaft of the electric cylinder inside the feeding table.

[0008] The upper turntable has a connecting shaft at its top. The connecting shaft passes through the bottom surface of the bracket and extends into the inner cavity of the bracket. Both the lifting shaft and the connecting shaft are connected to the servo motor inside the feeding table or the bracket through a transmission structure.

[0009] As a further description of the above technical solution:

[0010] The top of the feeding platform is provided with an installation groove, and several conveying rollers are arranged at intervals along the conveying direction of the plate in the installation groove. The ends of the conveying rollers are connected to the drive motor in the feeding platform through roller shafts.

[0011] As a further description of the above technical solution:

[0012] The conveying roller corresponding to the position of the lower turntable has a guide frame at one end near the lower turntable. The corresponding roller shaft rotatably passes through the guide frame and connects to the guide wheel, which is located on the outside of the lower turntable.

[0013] As a further description of the above technical solution:

[0014] The transmission structure includes a drive gear, a transition gear, and a driven gear positioned on corresponding gear shafts and sequentially meshed on the sides. The drive gears corresponding to the lower turntable and the upper turntable are respectively positioned on the same gear shaft, and the gear shaft is connected to the drive shaft of the servo motor.

[0020] Beneficial effects:

[0021] In use, the sheet metal rotating device of this invention operates as follows: when the sheet metal is conveyed between the lower and upper turntables via conveyor rollers, an electric cylinder lifts the lifting shaft and the lower turntable, which then clamps the sheet metal. Subsequently, a servo motor drives the gear shaft to rotate, and through corresponding gear linkage, the lifting shaft and connecting shaft rotate. This rotation of the lower and upper turntables causes the sheet metal to rotate and change edges, facilitating subsequent continuous grinding of the sheet metal's multiple edges. By clamping the sheet metal before rotation, the stability of the rotation is improved, ensuring more precise and accurate rotation, reducing wear on the sheet metal, and enhancing the accuracy of subsequent edge grinding.

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 scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Please see Figure 1-3 This utility model provides a technical solution: a plate rotating device for edge grinding, comprising:

[0031] Feeding table 1;

[0032] The lower turntable 2 has its bottom connected to the lifting shaft 3. The lifting shaft 3 passes through the top surface of the feeding table 1 and extends into the inner cavity of the feeding table 1. It is coaxially connected to the output shaft 5 of the electric cylinder 4 inside the feeding table 1.

[0033] The support 6 is arranged on the side of the feeding table 1 and extends above the lower turntable 2;

[0034] The upper turntable 7 has a connecting shaft 8 at its top. The connecting shaft 8 passes through the bottom surface of the bracket 6 and extends into the inner cavity of the bracket 6. The lifting shaft 3 and the connecting shaft 8 are both connected to the servo motor 9 inside the feeding table 1 or the bracket 6 through a transmission structure.

[0035] The top of the feeding platform 1 is provided with a mounting groove 10. Several conveying rollers 11 are spaced apart within the mounting groove 10 along the conveying direction of the sheet material 100. The ends of the conveying rollers 11 are connected to the drive motor inside the feeding platform 1 via roller shafts 12. The conveying rollers 11 corresponding to the position of the lower turntable 2 have guide frames 13 at their ends near the lower turntable 2. The corresponding roller shafts 12 rotatably pass through the guide frames 13 and connect to guide wheels 14, which are located on the outer side of the lower turntable 2. This improves the conveying efficiency and feeding stability of the sheet material 100.

[0036] The transmission structure includes a drive gear 15, a transition gear 16, and a driven gear 17, which are positioned on corresponding gear shafts 18 and sequentially meshed on their sides. The drive gears 15 corresponding to the lower turntable 2 and the upper turntable 7 are positioned on the same gear shaft 18, and this gear shaft 18 is connected to the drive shaft of the servo motor 9. The drive gear 15 corresponding to the lower turntable 2 is positioned on the lifting shaft 3, and the drive gear 15 corresponding to the upper turntable 7 is positioned on the connecting shaft 8. The transmission structure enables synchronous rotation drive of the lower turntable 2 and the upper turntable 7 to ensure the stability of the rotation and reversal drive of the plate 100, avoid wear and displacement between the plate 100 and the lower turntable 2 and the upper turntable 7, which would affect the quality of the plate 100 and prevent the plate 100 from not rotating into position.

[0037] The end of the gear shaft 18 is rotatably connected to a bearing seat 19 on the inner wall of the feeding table 1 or the bracket 6. A limiting bracket 20 is provided inside the feeding table 1 or the bracket 6 and sleeved on the corresponding gear shaft 18. This further improves the structural stability of the transmission structure.

[0038] The working principle of the plate rotation device for edge grinding in this embodiment includes: during use, the position of the plate 100 is sensed by a sensor (a sensor commonly used for workpiece position sensing is sufficient). When the plate is conveyed between the lower turntable 2 and the upper turntable 7 by the conveying roller 11, the electric cylinder 4 lifts the lifting shaft 3 and the lower turntable 2, and the lower turntable 2 and the upper turntable 7 clamp the plate 100. Then, the servo motor 9 drives the gear shaft 18 to rotate, and the lifting shaft 3 and the connecting shaft 8 are rotated through the corresponding gear linkage. Thus, the rotation of the lower turntable 2 and the upper turntable 7 drives the plate 100 to rotate and change edges, so that the multiple edges of the plate 100 can be ground in the subsequent process.

[0039] In summary, due to the adoption of the above technical solution, the plate rotation device for edge grinding in this embodiment has the following advantages compared with the prior art:

[0040] In use, the sheet metal rotating device of this invention operates as follows: when the sheet metal is conveyed between the lower and upper turntables via conveyor rollers, an electric cylinder lifts the lifting shaft and the lower turntable, which then clamps the sheet metal. Subsequently, a servo motor drives the gear shaft to rotate, and through corresponding gear linkage, the lifting shaft and connecting shaft rotate. This rotation of the lower and upper turntables causes the sheet metal to rotate and change edges, facilitating subsequent continuous grinding of the sheet metal's multiple edges. By clamping the sheet metal before rotation, the stability of the rotation is improved, ensuring more precise and accurate rotation, reducing wear on the sheet metal, and enhancing the accuracy of subsequent edge grinding.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
