A slide rail is fixedly connected to the side of the base, and a motor one is arranged on the surface of the slide rail. The output shaft of the motor one is fixedly connected to a threaded rod one, and a connecting plate is threadedly connected to the surface of the threaded rod one. In the process of implementing this technical solution, the inventor found that there are at least the following problems in the prior art:

[0004] When the above device is actually used, limited by the volume of the grinding wheel, the grinding efficiency is low. And after grinding the upper surface of the sheet metal part, it is necessary to release the fixation of the sheet metal part and then turn the sheet metal part over, which wastes manpower and is difficult to operate, and is relatively inconvenient to use.

[0005] It should be noted that the information disclosed in this background art section is only intended to increase the understanding of the overall background of the present utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art. Therefore, the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Summary of the Utility Model

[0006] In view of this, the purpose of the present utility model is to provide a device for removing burrs from the edges of sheet metal parts to solve the problems raised in the above background art.

[0007] The device for removing burrs from the edges of sheet metal parts provided by the present utility model includes a fixed frame. A flipping assembly is arranged outside the fixed frame. A placing plate is rotatably arranged inside the fixed frame. A placing groove is opened inside the placing plate. A grinding assembly is arranged at the top of the fixed frame. Moving grooves are opened on both sides at the top of the placing plate. Clamping plates are arranged inside the moving grooves. Fixed legs are fixedly connected to the bottom of the fixed frame.

[0008] Preferably, the flipping assembly includes rotating rods rotatably arranged on both sides of the fixed frame. One end of each rotating rod is fixedly connected to one side of the placing plate, and the other end of the rotating rod is fixedly connected to a turntable. Positioning blocks are fixedly connected to both sides of the fixed frame. A plug rod is inserted into the top of the positioning block, and slots for cooperating with the plug rod are formed at the top and bottom of the turntable.

[0009] Preferably, the grinding assembly includes a first lead screw rotatably arranged inside the fixed frame. A moving frame is screwed onto the first lead screw. A moving block is slidably arranged on the inner wall of the moving frame. One side of the moving block is rotatably connected to a grinding roller through a rotating shaft. A spring is arranged at the top of the moving block. One side of the moving block is fixedly connected to a first motor, and the output end of the first motor is fixedly connected to one end of the grinding roller through a rotating shaft.

[0010] Preferably, a guide rod is fixedly connected to the inner wall of the fixed frame, and the outer side of the guide rod is slidably matched with the inner wall of the moving frame.

[0011] Preferably, a second motor is fixedly connected to the inner wall of the fixed frame, and the output end of the second motor is fixedly connected to one end of the first lead screw.

[0012] Preferably, a dual-axis motor is arranged inside the placing plate. Second lead screws are fixedly connected to both ends of the dual-axis motor. The outer sides of the second lead screws are threadedly matched with the inner walls of the clamping plates. Moving wheels are arranged at the bottoms of the fixed legs.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] For this burr removal device for machining the edges of sheet metal parts, place the sheet metal part in the placement groove inside the placing plate. Through the two clamping plates moving towards each other in the moving grooves, the sheet metal part is clamped and fixed. The rotation of the first lead screw drives the moving frame to move left and right reciprocally. The first motor drives the grinding roller to rotate, and the surface of the sheet metal part is ground. Under the elastic force of the spring, a downward pressure is generated on the moving block, making the grinding roller closely adhere to the surface of the sheet metal part, improving the grinding effect and efficiency. After grinding and deburring the four sides of the sheet metal part in sequence, then place the sheet metal part face-up in the placement groove, and then fix the sheet metal part through the clamping plates, and grind the upper surface of the sheet metal part. After the upper surface grinding is completed, move the moving frame to the side far away from the placing plate. By pulling out the plug rod, the plug rod is separated from the slot at the top of the turntable, releasing the positioning of the turntable, so that the placing plate rotates in the fixed frame through the rotating rod, and then fix the turntable by inserting the plug rod into the slot, and position the placing plate, thereby facilitating the grinding of the bottom surface of the sheet metal part.

The output end of the first motor 46 is fixedly connected to one end of the grinding roller 44 through a rotating shaft.

[0032] It should be noted that: Place the sheet metal part in the placing groove 301 inside the placing plate 3. Clamp and fix the sheet metal part by moving the two clamping plates 6 towards each other in the moving grooves 5. Rotate the first lead screw 41 to drive the moving frame 42 to move left and right reciprocally. The first motor 46 drives the grinding roller 44 to rotate to grind the surface of the sheet metal part. Under the elastic force of the spring 45, a downward pressure is generated on the moving block 43 to make the grinding roller 44 closely adhere to the surface of the sheet metal part, improving the grinding effect and efficiency. After grinding and deburring the four sides of the sheet metal part in sequence, then place the sheet metal part face up in the placing groove 301, and then fix the sheet metal part through the clamping plate 6 to grind the upper surface of the sheet metal part. After the upper surface grinding is completed, move the moving frame 42 to the side away from the placing plate 3. Pull out the inserting rod 24 to separate the inserting rod 24 from the inserting slot 25 at the top of the turntable 22, release the positioning of the turntable 22, so that the placing plate 3 rotates in the fixed frame 1 through the rotating rod 21, and then fix the turntable 22 by inserting the inserting rod 24 into the inserting slot 25 to position the placing plate 3, thereby facilitating the grinding of the bottom surface of the sheet metal part.

[0038] When in use, place the sheet metal part in the placement groove 301 inside the placement plate 3. The two clamping plates 6 move towards each other in the moving groove 5 to clamp and fix the sheet metal part. The rotation of the first lead screw 41 drives the moving frame 42 to reciprocate left and right. The first motor 46 drives the grinding roller 44 to rotate to grind the surface of the sheet metal part. Under the elastic force of the spring 45, a downward pressure is generated on the moving block 43, so that the grinding roller 44 closely adheres to the surface of the sheet metal part, improving the grinding effect and efficiency. After grinding and deburring the four sides of the sheet metal part in sequence, place the sheet metal part face up on the placement groove 301 again, and then fix the sheet metal part through the clamping plate 6 to grind the upper surface of the sheet metal part.
