A cutting blade for processing the outside of the die-casting is arranged on the outer side of the lower part of the round tube, which can grind the inside of the inner hole and the outside of the die-casting. When the round tube extends into the inner hole, the rotating round tube can clean the burrs at the hole mouth through the second tool. Since the second tool is movable, the die-casting itself will not be damaged while cleaning the burrs in the hole (because the second tool is driven by the spring force of the spring, when the second tool contacts the inner wall of the inner hole, the inner wall of the inner hole will block the second tool, thereby not damaging the die-casting itself). 4.

If the adsorption hood of the unloading conveying mechanism cannot be stuck on the outside of the die-casting, it can be considered to a certain extent that the die-casting has not been cut, so that the die-casting cannot be covered by the adsorption hood, and the die-casting can be further cut; on the other hand, if there is no problem with the cutting of the die-casting, but the adsorption hood cannot be stuck on the outside of the die-casting, it can be proved that the die-casting is too large, larger than the design size, and is a defective product; in summary, the judgment of cutting accuracy and product size can be achieved to a certain extent.

[0038] like Figure 1 and 10 The pre-cutting mechanism 2 includes two first brackets 22, and a pre-cutting roller 21 is rotatably installed between the two first brackets 22. When the pre-cutting roller 21 rotates, the burrs on the top of the die-casting can be removed. A motor seat is installed on one side of each first bracket 22, and the motor seat is installed with a first driving component 23 for driving the pre-cutting roller 21 to rotate. A vertical pole is installed on the support plate outside the first bracket 22 adjacent to the motor seat, and the vertical pole is sleeved with a first spring 24. The two ends of the first spring 24 are respectively against the support plate and the motor seat. The first spring 24 acts like a gasket to prevent the motor seat from loosening.

The lifting screw 34 is driven to rotate by the driving motor 32, and then the lifting nut 35 is matched to realize the lifting of the lifting frame 33; a horizontal driving module 36 is adjustably installed at the bottom end of the lifting frame 33, and the horizontal driving module 36 drives the sliding seat 37 to move back and forth, and the bottom end of the sliding seat 37 is adjustable The adsorption hood 38 is installed on the ground, and the die-casting can be adsorbed by the adsorption hood 38 (it is necessary to ensure that the adsorption force is sufficient to lift the die-casting). This device does not require manual feeding, and the die-casting can be loaded and unloaded through the conveying mechanism; the internal size of the adsorption hood 38 of the loading conveying mechanism 3 is slightly larger than the internal size of the adsorption hood 38 of the unloading conveying mechanism 6, and the internal size of the adsorption hood 38 of the unloading conveying mechanism 6 is slightly larger than the external size of the die-casting after cutting. If the adsorption hood 38 of the unloading conveying mechanism 6 cannot be stuck on the outside of the die-casting, it can be considered to a certain extent that the die-casting has not been cut, so that the die-casting cannot be covered by the adsorption hood 38, and the die-casting can be further cut; on the other hand, if there is no problem with the cutting of the die-casting, but the adsorption hood 38 cannot be stuck on the outside of the die-casting, it can be proved that the die-casting is too large, larger than the design size, and is a defective product. The adsorption hood 38 is connected to an external air path. In summary, the judgment of cutting accuracy and product size can be achieved to a certain extent.

[0040] like Figure 2-7 The main body 4 of the positioning and cutting device includes a frame 41, a positioning fixture seat 42 is installed on the top of the frame 41, an edge and inner hole cutting assembly 43 for cutting the edge and inner hole of the die casting is installed on the top of the frame 41, and a downward pressing cutting assembly 44 is also installed on the top of the frame 41.

The burrs on the side of the die casting can be pre-processed by the downward pressing cutting assembly 44, and the side of the die casting can be finely processed and the inner hole of the die casting can be processed by the edge and inner hole cutting assembly 43;

[0041] like Figure 2-7The edge and inner hole cutting assembly 43 includes a first cutting assembly 4315 and a second cutting assembly 4316 that move in a three-dimensional space.

Since the second tool is movable, the die-casting itself will not be damaged while cleaning the burrs in the hole (because the second tool is driven by the spring force of the spring, when the second tool contacts the inner wall of the inner hole, the inner wall of the inner hole will block the second tool, thereby not damaging the die-casting itself).

[0042] like Figure 2-7The downward pressure adjustment component is composed of a threaded head 43165, a second spring 43166 and a pressure head 43167. The pressure head 43167 acts on the second tool 43163. The second spring 43166 is located between the threaded head 43165 and the pressure head 43167. The threaded head 43165 is adjustably installed in the round tube 43161. By adjusting the depth of rotation of the threaded head 43165, the compression degree of the second spring 43166 can be adjusted, thereby realizing the adjustment of the pressure of the pressure head 43167, which can be reasonably adjusted according to the needs of cleaning; the bottom of the pressure head 43167 is an inverted truncated cone structure, and the second tool 43163 is located at one end of the pressure head 43167 and is provided with an obtuse groove 431632 that cooperates with the inverted truncated cone structure, and the angle of the obtuse groove 431632 is 100° The obtuse groove 431632 can cooperate well with the inverted truncated cone structure of the pressure head 43167. When the second tool 43163 rotates, the obtuse groove 431632 does not affect the rotation of the second tool 43163; the second tool 43163 is arranged at one end away from the pressure head 43167 as an inclined structure 43168, and the inclined structure 43168 facilitates the second tool 43163 to be inserted into the inner hole of the die casting, and avoids the second tool 43163 from being stuck outside the inner hole (when the inclined structure 43168 contacts the edge of the opening end of the inner hole, the edge of the opening end of the inner hole can squeeze the inclined structure 43168, so that the second tool 43163 is inserted into the inner hole of the die casting), and a pin shaft 43162 is arranged on the round tube 43161, and the second tool 43163 is provided with an inclined groove 431631 cooperating with the pin shaft 43162.

[0043] like Figure 2-7 The edge and inner hole cutting assembly 43 includes a moving frame 4304 and two parallel slide rail seats 4301. The moving frame 4304 is slidably mounted on the two slide rail seats 4301. One side of the slide rail seat 4301 is equipped with two first photoelectric switches 4302 for sensing the position of the moving frame 4304. The moving frame 4304 is driven by a first servo linear module 4303. The first servo linear module 4303 can drive the moving frame 4304 to move forward and backward. When cutting the edges of the left and right sides of the die casting, if the first cutting assembly 4315 is used, it is only necessary to align the first cutting assembly 4315 with the edge of the die casting, and the burrs on the edge can be cleaned by driving the moving frame 4304 to move forward and backward. If grinding is required, the first cutting assembly 4315 is rotated to the side away from the die casting; the second cutting assembly 4316 is fitted with the die casting, and the round tube of the second cutting assembly 4316 is driven to rotate, and the outside can be grinded by the cutting blade 43164;

[0044] like Figure 2-7, a horizontal moving seat 4308 is slidably installed on one side of the moving frame 4304, and the moving frame 4304 is installed with a third servo linear module 4311 for driving the horizontal moving seat 4308, and two second photoelectric switches 4306 for sensing the horizontal moving seat 4308 are installed on the top of the moving frame 4304 (the two second photoelectric switches 4306 are used to limit the moving range of the horizontal moving seat 4308). When cutting the edges of the front and rear sides of the die-casting, if the first cutting component 4315 is used, it is only necessary to align the first cutting component 4315 with the edge of the die-casting, and the burrs on the edge can be cleaned by driving the horizontal moving seat 4308 to move left and right. If grinding is required, the first cutting component 4315 is rotated to the side away from the die-casting; the second cutting component 4316 is fitted with the die-casting, and the round tube of the second cutting component 4316 is driven to rotate, and the outside can be grinded by the cutting blade 43164;

Two third photoelectric switches 4307 for sensing the lifting seat 4310 are installed on one side of the horizontal moving seat 4308; by adjusting the height of the lifting seat 4310, the height of the second cutting assembly 4316 can be adjusted, so that the second cutting assembly 4316 can cut die-castings of different heights.

[0046] like Figure 2-7The lifting seat 4310 is provided with a first motor 4305, a second motor 4313 and a rotating shaft seat 4314 on one side. The rotating shaft seat 4314 is rotatably provided with a rotating shaft 4318. A top synchronous pulley is fixedly provided on the top of the rotating shaft 4318. The synchronous pulley 4312 of the output shaft of the second motor 4313 and the top synchronous pulley are connected by a synchronous belt. The rotating shaft 4318 can be driven to rotate by the second motor 4313, thereby driving the second cutting assembly 4316 to rotate. A bottom synchronous pulley is rotatably provided on the lower part of the rotating shaft 4318, for example, the rotating shaft 4318 and the bottom synchronous pulley are connected by a bearing. In contrast, the rotating shaft 4318 and the top synchronous pulley are fixedly provided, and the two rotate synchronously; the rotating shaft 4318 and the top synchronous pulley are rotatably provided, and the two rotate asynchronously.
