Detailed Implementation

[0028] The present invention will be further described below with reference to specific embodiments. The invention is explained through illustrative embodiments and descriptions, but is not intended to limit the invention.

[0029] Example: Figures 1-10 The high-strength aerospace aluminum alloy cutting and grinding integrated device shown includes a processing mechanism 1 and an alloy plate 2. The processing mechanism 1 includes a base frame 101.

[0030] The base frame 101 has a frame fixed shaft 101-1 on both sides of one end, and a frame round hole 101-6 on both sides of the other end. Two vertical supports are also fixedly installed on one side of the base frame 101, and each support has a frame sliding hole 101-7.

[0032] The swing shaft 104-1 is rotatably connected to the round hole 101-6 of the frame. A spring 103 is provided between the swing pull shaft 104-4 and the frame shaft 101-1.

[0033] The lower part of the base frame 101 and close to one end of the spring 103 is provided with a long conveying belt 102 and a short conveying belt 106, and a gap is arranged between the long conveying belt 102 and the short conveying belt 106, which is needed for cutting and also determines the length of the cut plate.

In addition, a sensor is arranged on the bracket on which the long conveying belt 102 is installed and close to one side of the short conveying belt 106. The sensor is realized by using the existing technology to identify the position of the alloy plate 2. The gap between the long conveying belt 102 and the short conveying belt 106 and below the cutting sawtooth knife 117 is the initial cutting position.

[0040] The grinding belt includes a grinding frame 113, with a grinding shaft 125 rotatably mounted at each of the four corners of the grinding frame 113. One of the grinding shafts 125 is fixedly connected to the output shaft of the grinding motor 124, which is fixedly mounted on the grinding frame 113. Grinding sanding belts 126 are sleeved on the four grinding shafts 125. A raised slider is provided at the bottom of the grinding frame 113. The long section of the grinding L-connector 114 is hinged to the grinding frame 113.

[0041] The base frame 101 is also provided with clamping rods on both sides. The clamping rods include two axisymmetric telescopic wheels. The telescopic wheels include clamping cylinders 101-2. The clamping cylinders 101-2 are fixedly installed on the base frame 101. The movable end of the clamping cylinders 101-2 is rotatably mounted with a clamping roller 101-3. The movable ends of the two clamping cylinders 101-2 are rotatably connected by a clamping crossbar 101-4.

[0042] The base frame 101 is also equipped with a small roller 101-5 that rotates with the bracket, and the small roller 101-5 cooperates with the large cam 108.

[0043] A guide groove 105-2 is fixedly installed on the guide frame 105. The guide groove 105-2 is slidably connected to the swing protrusion shaft 104-2. The swing protrusion shaft 104-2 is set on the swing frame 104. A guide bracket 105-3 is fixedly connected to the top of the guide frame 105. The guide bracket 105-3 is slidably connected in the frame sliding hole 101-7. A guide slide 105-1 is provided at the bottom of the guide frame 105. The protruding slider at the bottom of the grinding frame 113 is slidably set in the guide slide 105-1.

[0044] The working principle of this invention is as follows: First, according to the required cutting angle, the angle of the cutting serrated blade 117 is selected and adjusted. Specifically, the hydraulic cylinder 123 is activated to push the cutting beam 118 to slide within the arc-shaped slide groove 120, thereby adjusting the angle of the cutting serrated blade 117. Then, a complete alloy plate 2 is placed on the long conveyor belt 102. The long conveyor belt 102 and the short conveyor belt 106 are started to run simultaneously in the same direction and at the same speed, transporting the other end of the alloy plate 2 to the short conveyor belt 106. The position is located by the sensor. The alloy plate 2 first reaches the gap between the long conveyor belt 102 and the short conveyor belt 106, and is located below the cutting serrated blade 117, and then stops moving. This process is to locate the initial position. Then, the running time is input in the control program. Assuming the running time is 4 seconds, the long conveyor belt 102 and the short conveyor belt 106 run simultaneously for 4 seconds and then stop.

[0045] Activating the four clamping cylinders 101-2 causes the clamping rollers 101-3 to descend, using the clamping rollers 101-3 to press the alloy plate 2 firmly against it, preventing it from moving. Figure 2 As shown, the main motor 107 is started, driving the large cam 108 to rotate counterclockwise. Under the action of the large cam 108 and the small roller 101-5, the lowest point on the large cam 108 contacts the small roller 101-5, the spring 103 is compressed, the swing frame 104 descends, and the cutting box 112 also descends. As the large cam 108 continues to rotate (at this time, the motion trajectory of the large cam 108 is still on the small arc), the upper connecting rod 110 drives the cutting connecting rod 111 to rotate, thereby pulling the cutting box 112 to slide, and using the cutting box 112 to cut the alloy plate 2, as shown. Figure 2 As shown, pull the cutting box 112 from left to right to complete the cutting.

[0046] When the aforementioned swing frame 104 descends, the swing protrusion shaft 104-2 slides within the guide groove 105-2, causing the guide frame 105 to descend, and the position of the grinding frame 113 also changes from... Figure 9 The location, arrive Figure 10 In the middle position, as the large cam 108 continues to rotate (at this time, the motion trajectory of the large cam 108 is still on the large arc), the upper gear 109 and the lower gear 115 continue to mesh, and the lower connecting rod 116 drives the grinding L connecting rod 114 to rotate, thereby pushing the grinding frame 113 as... Figure 10 As shown, sliding from left to right, the two cut surfaces of the alloy sheet 2 are simultaneously polished.

[0047] After polishing is complete, the swing bracket 104 will return to its initial position, as follows: Figure 2As shown, after the alloy plate 2 is polished, the clamping cylinder 101-2 is activated to release the fixation of the two sections of alloy plate 2. At this time, the alloy plate 2 on the short conveyor belt 106 is cut into plates with a length of 20cm according to the set running time. Then, the plate that has been cut and polished is transported to the next location.

[0048] When the complete alloy sheet 2 is placed onto the long conveyor belt 102 for the first time, a sensor is needed for positioning so that the alloy sheet 2 can reach the initial cutting position after being placed on the long conveyor belt 102. After the previous cutting is completed, subsequent cutting does not require repositioning because one end of the remaining alloy sheet 2 is still in the initial cutting position after the previous cutting. That is, after the first cutting saw blade 117 finishes cutting, one end of the alloy sheet 2 is already in the initial cutting position. Therefore, by setting the running time of the long conveyor belt 102 and the short conveyor belt 106 each time, alloy sheets 2 of different lengths with polished cut surfaces can be obtained.

[0049] Any aspects not covered in this invention are applicable to existing technologies.
