Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal grinding, in particular to a sheet metal end angle grinding device. Background Art

[0002] The end angle of sheet metal parts, as a key part in sheet metal processing, has the function of connecting, strengthening and protecting parts. According to different size and shape characteristics, sheet metal angles can be divided into multiple categories, such as linear sheet metal angles, etc. These different types of sheet metal angles are suitable for different application scenarios and needs. Among them, the end angles of sheet metal parts need to be polished during production.

[0003] For example, the Chinese patent "A sheet metal surface grinding device" with announcement number CN220613445U includes a connecting plate and a grinding belt, a sheet metal body is arranged between the connecting plate and the grinding belt, a lifting cylinder is installed in the middle of the upper surface of the connecting plate, and the lifting cylinder is connected to the external bracket; a plurality of through holes are evenly opened on the connecting plate, and auxiliary limit columns for pressing the four corners of the sheet metal body are installed on the plurality of through holes; two through grooves are symmetrically opened in the middle of the connecting plate, and limit side baffles are respectively installed inside the two through grooves.

[0004] Although the above-mentioned prior art can realize the grinding of the end angles of sheet metal parts, in actual use, on the one hand, the grinding effect of sheet metal parts is not good enough. Usually, when grinding the end angles of sheet metal parts, the operator needs to hold the grinding device for grinding, which makes it easy to offset during the movement of the grinding device, thereby affecting the grinding effect. On the other hand, after grinding one end of the sheet metal part, the operator needs to adjust the position of the sheet metal part and grind the other end angles of the sheet metal part. As a result, the operator needs to make adjustments every time the sheet metal part is ground, thereby increasing the workload of the operator. Therefore, it does not meet the existing needs. In this regard, we propose a sheet metal end angle grinding device. Utility Model Content

[0005] The purpose of the utility model is to provide a sheet metal end angle grinding device to solve the problem that the grinding effect of the sheet metal parts proposed in the above background technology is not good enough, and the operator needs to adjust the position of the sheet metal part after grinding one end of the sheet metal part.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sheet metal end angle grinding device, comprising a frame, a workbench is fixedly arranged on the upper end of the frame, a first mounting frame is fixedly arranged on one side of the upper end of the workbench, and a second mounting frame is fixedly arranged on the other side of the upper end of the workbench; and further comprising:

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can reduce the auxiliary operation of the operator by the driving motor and the double-headed motor. When grinding the end angle of the sheet metal part, the sheet metal part is first fixed on the moving seat, and the driving motor is turned on at this time, so that the output shaft of the driving motor drives the first roller to rotate in the limiting groove, and the moving seat is moved together with the sheet metal part through the first roller until the moving seat moves to a suitable position, and then the double-headed motor is turned on again, so that the output shaft of the double-headed motor drives the second roller to rotate in the slide groove, and at the same time, the sliding plate drives the grinding disc to move to the front end inside the slide groove through the second roller. At this time, the grinding disc is adjusted to make the grinding disc contact with the sheet metal part and the double-headed motor is turned on again, so that the double-headed motor drives the sliding plate to drive the rotating grinding disc to move to the rear end inside the slide groove, thereby avoiding the situation that the grinding device is shifted in position when being moved by the operator, thereby improving the grinding effect of the end angle of the sheet metal part.

[0017] 2. The utility model can make the adjustment of sheet metal parts more flexible through the suction cup and the first rotating motor. After the sheet metal part is polished at one place, the movable seat is moved together with the sheet metal part to the bottom of the first mounting frame by driving the motor. At this time, the first hydraulic telescopic device is turned on to extend the telescopic end of the first hydraulic telescopic device. The extension of the telescopic end of the first hydraulic telescopic device drives the suction cup assembly to move downward together with the suction cup until the suction cup contacts the upper end of the sheet metal part. At this time, the air inside the suction cup is extracted to generate negative pressure inside the suction cup and fix the sheet metal part by adsorption. At this time, the first rotating motor is turned on to make the output shaft of the first rotating motor drive the suction cup to rotate together with the sheet metal part until the sheet metal part is rotated to a suitable position. At this time, the sheet metal part is re-fixed on the movable seat, and the new end angle on the sheet metal part is polished, which simplifies the polishing steps of the sheet metal part and reduces the workload of the operator.

[0018] 3. The utility model can fix the sheet metal during grinding through the third hydraulic telescopic device and the positioning plate. Before grinding, the sheet metal is placed on the moving seat. At this time, the third hydraulic telescopic devices at both ends are synchronously opened to extend the telescopic end of the third hydraulic telescopic device. The extension of the telescopic end of the third hydraulic telescopic device pushes the positioning plate to move until the positioning plate contacts the sheet metal and squeezes and fixes it. If the sheet metal is not located at the center position of the moving seat, the positioning plate pushes the sheet metal during the movement until the sheet metal moves to the center position of the moving seat, thereby improving the adaptability of the grinding device to sheet metals of different sizes. At the same time, the sheet metal can be positioned by the positioning plate. BRIEF DESCRIPTION OF THE DRAWINGS
