[0023] As attached Figure 1 To be continued Figure 3 As shown:

[0024] This utility model provides a precision machine tool sheet metal shell chamfering device, including a chamfering integrated frame 1, a chamfering conveyor 2, a support frame 3, a sheet metal product 4, a downward conveyor 5, a pressing wheel 6, a transmission box 7, a chamfering motor 8, and a chamfering wheel 9. The chamfering integrated frame 1 is provided with a chamfering conveyor 2 at the lower inner side. The support frame 3 is installed on the chamfering conveyor 2. The sheet metal product 4 is placed on the chamfering conveyor 2. The sheet metal product 4 is restricted by the downward conveyor 5 above. The downward conveyor 5 is connected to the chamfering integrated frame 1. The pressing wheel 6 is rotatably installed inside both the chamfering conveyor 2 and the downward conveyor 5.

[0025] Two transmission boxes 7 are installed on the outside of the chamfering integrated frame 1. The input end of each transmission box 7 is fixed to the output end of the chamfering motor 8 installed outside it. The transmission box 7 has multiple output ends, and each output end is fixedly installed with a single chamfering wheel 9. There are two sets of chamfering wheels 9, and the chamfering wheels 9 are located on the inside of the chamfering integrated frame 1.

[0026] Furthermore, the chamfering integrated frame 1 includes a frame 11, a crossbeam plate 12, an extension plate 13, a hydraulic cylinder driver 14, and a lifting frame 15. Two frames 11 are provided, with a chamfering conveyor 2 installed below them for conveying the sheet metal product 4 to be processed. A transmission box 7 is installed on the outside of each frame 11 to drive the rotation of the chamfering wheels 9. Simultaneously, a set of chamfering wheels 9 is provided on the inner side of each frame 11 for chamfering and grinding the edges of the sheet metal product 4. In addition, the crossbeam plate 12 and the extension plate 13 are fixedly installed above both frames 11, providing stable support for the equipment.

[0027] Furthermore, each set of chamfering wheels 9 consists of several upper grinding wheels and several lower grinding wheels, which are parallel to each other and laterally distributed on both sides of the chamfering conveyor 2 and the lower pressing conveyor 5. These chamfering wheels 9 all adopt a conical design, which can more effectively chamfer and grind the edges of the sheet metal product 4. Driven by the transmission box 7, the chamfering wheels 9 can rotate at high speed to complete the chamfering operation on the sheet metal product 4.

[0028] Furthermore, both the chamfering conveyor 2 and the pressure conveyor 5 are belt conveyors, and several pressure rollers 6 are arranged laterally inside them. These pressure rollers 6 are located inside the belt, which can effectively limit the deformation of the belt during the conveying process and ensure the stability of the conveying. At the same time, the belt widths of the chamfering conveyor 2 and the pressure conveyor 5 are the same, but the length of the chamfering conveyor 2 is slightly greater than that of the pressure conveyor 5. This design allows the sheet metal product 4 to be picked up at both ends and rotated 180 degrees. After the two ends of the sheet metal product 4 extend outward and come into contact with the chamfering rollers 9, the chamfering operation can be completed.

[0029] Furthermore, the pressure conveyor 5 is located directly above the center of the chamfering conveyor 2. Their belts have the same width but different lengths. This design allows the sheet metal product 4 to be stably pressed down by the pressure conveyor 5 during transport, while its ends extend outwards to contact the chamfering wheel 9 for chamfering operations. In addition, space is provided at both the front and rear ends of the chamfering conveyor 2 to prevent the sheet metal product 4 from being restricted by the pressure conveyor 5 at these locations, facilitating the loading, unloading, and rotation of the sheet metal product 4.

[0030] Furthermore, the front end of the chamfering conveyor 2 is a pick-and-place end, used for placing and removing the sheet metal product 4 to be processed; while the rear end is the product turning end. Above the rear end of the chamfering conveyor 2, a downward rotary cylinder 16 is installed on the outer extension plate 13, and a magnetic suction head 17 is fixedly installed on its output end. After the sheet metal product 4 completes one chamfering operation, the downward rotary cylinder 16 will drive the magnetic suction head 17 to descend and attract the sheet metal product 4, and then turn it 180 degrees horizontally. Afterwards, the chamfering conveyor 2 will reverse the direction to convey the sheet metal product 4, so that it passes through the chamfering wheel 9 again to complete the chamfering operation of the remaining edges.

[0031] Furthermore, the magnetic suction head 17 is located above the rear end of the chamfering conveyor 2. Its main function is to magnetically hold the sheet metal product 4 that has completed one chamfering operation. Driven by the downward rotating cylinder 16, the magnetic suction head 17 can accurately hold the sheet metal product 4 and rotate it horizontally by 180 degrees. In this way, the sheet metal product 4 can pass through the chamfering wheel 9 again to complete the chamfering operation of the remaining edges. The design of the magnetic suction head 17 makes the equipment more automated and improves production efficiency.

[0032] The working principle is as follows: First, the sheet metal product 4 to be processed is precisely placed on the front end of the belt of the chamfering conveyor 2, ensuring that both ends of the sheet metal product 4 can extend and protrude outside the conveyor so as to contact the subsequent chamfering wheel 9.

[0033] Next, the chamfering conveyor 2 is activated to begin conveying the sheet metal product 4 forward. When the sheet metal product 4 is conveyed to the area below the pressure conveyor 5, the pressure conveyor 5 will descend in a timely manner, cooperating with the chamfering conveyor 2 to stably clamp and convey the sheet metal product 4.

[0034] During transport, the sheet metal product 4 undergoes grinding by two sets of chamfering wheels 9. These chamfering wheels 9 are driven by the transmission box 7, enabling them to rotate at high speed and perform precise chamfering on the edges of the sheet metal product 4. Because the chamfering wheels 9 adopt a tapered design, they can more effectively grind the edges of the sheet metal product 4, ensuring the consistency of the chamfering effect.

[0035] When the sheet metal product 4 is conveyed to the rear end of the chamfering conveyor 2, the conveyor stops working. At this time, the downward rotary cylinder 16 is activated, driving the magnetic suction head 17 to descend. The magnetic suction head 17 can accurately attract the sheet metal product 4 that has completed one chamfering operation and rotate it horizontally by 180 degrees.

[0036] After the rotation is completed, the chamfering conveyor 2 will start in reverse, conveying the sheet metal product 4 from the rear to the front. During the conveying process, the sheet metal product 4 will be ground again by two sets of chamfering wheels 9, thereby completing the chamfering of the remaining edges.

[0037] Finally, when sheet metal product 4 is conveyed to the front end of chamfering conveyor 2, the operator can easily remove it for further processing or treatment. The entire chamfering process is efficient and stable, ensuring that the chamfering effect of sheet metal product 4 meets the expected requirements.

[0038] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
