Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that the description is illustrative only, and is not to be construed as limiting the scope of the invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "connected," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
After the aluminum die casting is formed in a die-casting mode, burrs in various forms exist due to the structure of the die and the flash phenomenon. The burrs to be removed of the aluminum die casting related to the embodiment comprise a material handle at the periphery of the outline, flash waste, hole burrs at the structural position of a lower surface hole and lower surface burrs caused by a mandril during die casting.
For such an aluminum die casting, as shown in fig. 1 and 2, the present embodiment provides a multi-dimensional flexible deburring apparatus for an aluminum die casting. Similarly to the conventional fine blanking apparatus, the fine blanking apparatus specifically includes an upper die assembly 100, a lower die assembly 200, a milling cutter assembly 300, a first driving mechanism (not shown), and a second driving mechanism 500.
As shown in fig. 3-5, the lower die assembly 200 includes a lower die base 20 and a positioning base 201 for positioning an aluminum die casting; the upper die assembly 100 includes an upper die base 10 and a cutting die 101 fixed below the upper die base 10, the cutting die 101 including an annular cutting edge M matching the contour of the aluminum die cast. A first drive mechanism (not shown) is used to drive the upper die assembly 100 up and down relative to the lower die assembly 200. When the upper die assembly 100 moves downwards, the annular cutting edge M of the cutting die 101 acts on the outline of the aluminum die casting positioned on the positioning seat 201, so that a material handle and flash waste materials on the periphery of the outline are removed.
In order to avoid the damage to the workpiece or equipment caused by the jump of the aluminum die casting due to uneven stress caused by the instantaneous action force of the pressing down of the upper die on the aluminum die casting, in the embodiment, a pressing block 102 is additionally arranged in the lower die assembly 200 for pressing the aluminum die casting during machining so as to keep the stability of the aluminum die casting.
Specifically, as shown in fig. 3 to 5, the upper die assembly 100 further includes a pressing block 102 located in the cutting die 101, the cutting die 101 is provided with a through slot S surrounded by the annular cutting edge M, and the pressing block 102 is located in the through slot S and can move up and down in the through slot S relative to the cutting die 101. Wherein a first elastic member 105 is disposed between the pressure holding block 102 and the upper die base 10. In the initial state, the first elastic member 105 is at the original length, and the pressing block 102 is at the lower limit position. When a first driving mechanism (not shown in the figure) drives the upper die assembly 100 to move downwards relative to the lower die assembly 200, the cutting die 101 approaches the aluminum die casting, the lower surface of the pressure holding block 102 in the cutting die 101 contacts the aluminum die casting, at this time, the cutting die 101 continues to descend, the first elastic piece 105 is compressed to apply acting force to the pressure holding block 102, and therefore the pressure holding block 102 is flexibly pressed on the aluminum die casting, namely, a certain pressure is maintained, and the aluminum die casting is prevented from being damaged. Meanwhile, the descending of the cutting die 101 enables the annular cutting edge M to act on the outer contour of the aluminum die casting, so that material handles and flash waste materials on the periphery of the contour are cut off.
When the upper die assembly 100 moves downwards, the pressing block 102 presses the aluminum die casting, so that the positioning seat 201 is indirectly subjected to downward pressure, at this time, if the positioning seat 201 is fixed, the positioning seat 201 and the aluminum die casting are easily excessively extruded to damage the surface of the aluminum die casting, and in other words, a milling cutter assembly 300 driven by the second driving mechanism 500 is further arranged below the aluminum die casting. For this purpose, a second elastic element 204 is disposed between the positioning base 201 and the lower die base 20, and the positioning base 201 is not rigidly fixed to the lower die base 20, but can be lifted up and down to some extent relative to the lower die base 20. When the upper die assembly 100 moves downwards, the lower end of the pressing block 102 elastically presses and holds the aluminum die casting, and the positioning seat 201 descends in a flexible damping mode relative to the lower die seat 20, so that the annular cutting edge M flexibly deburs the aluminum die casting in the first dimension.
Further, as shown in fig. 3 and 6, the milling cutter assembly 300 includes a plurality of rod-shaped milling cutters 301 mounted on a fixing frame 700, and the rod-shaped milling cutters 301 sequentially pass through the lower die holder 20 and the positioning base 201 from bottom to top to act on the aluminum die casting. The rod mill 301 can be used to remove orifice burrs, ejector pin burrs, and the like, depending on the extension length of the rod mill 301 and the configuration of the milling head. The rod mill 301 can move up and down to some extent with respect to the lower die assembly 200. A third elastic element 302 is arranged between the rod-shaped milling cutter 301 and the fixed frame 700, and the third elastic element 302 enables the rod-shaped milling cutter 301 to move elastically and automatically reset. The second driving mechanism 500 drives the rod-shaped milling cutter 301 to rotate through the transmission assembly 600, and the rotating rod-shaped milling cutter 301 is pressed to be in elastic telescopic contact with the aluminum die casting on the positioning seat 201 with flexible damping descending through the third elastic piece 302, so that flexible deburring of a second dimension is realized on the aluminum die casting through the milling head. This prevents the hole structure and the surface of the aluminum die-cast part from being adversely damaged, thereby improving the processing yield.
It should be noted that for the first dimension soft deburring and the second dimension soft deburring processes, the second driving mechanism 500 and the first driving mechanism (not shown) are simultaneously turned on for efficiency improvement, and even more, the second driving mechanism 500 is prior to the first driving mechanism (not shown). This is because the efficiency of the mill is often less than that of die cutting and therefore the mill generally requires more time.
In both cases, the second dimension flexible deburring is earlier than the first dimension flexible deburring, that is, the bar cutter 301 has been flexible deburred by virtue of its own elastic expansion and contraction while the cutter die 101 has not yet acted on the contour of the aluminum die cast. When the cutting die 101 needs to flexibly deburr in the first dimension, if the rod-shaped milling cutter 301 is not flexible and telescopic, the milling cutter abuts against the lower surface of the aluminum die casting, so that the aluminum die casting is jacked up, and the whole operation is affected. If only the rod-shaped milling cutter 301 can elastically stretch and retract and the positioning seat 201 is fixed, the aluminum die casting is damaged due to excessive downward acting force applied to the aluminum die casting under the influence of instantaneous acting force of die cutting. It can be seen that the flexible arrangement of the two dimensions is inseparable, and the one is not.
Preferably, as shown in fig. 3-4, the pressure holding block 102 includes an upper base a and a lower pressure holding body b, and the base a has a larger contour size than the pressure holding body b. The upper end surface of the cutting die 101 surrounds the limiting step 1 of the through groove S, the pressing block 102 moves downwards, and the base body a is limited by the limiting step 1. In this way, the movement of the pressure block 102 is limited, and the pressure block 102 does not come off the through groove S of the cutting die 101.
As shown in fig. 3-4, the upper die base 10 includes an upper die plate 103 and a die fixing plate 104, the die fixing plate 104 has a through hole, the lower surface of the upper die plate 103 has a recessed portion, so that a plurality of first grooves are formed on the lower surface of the upper die base 10, the upper surface of the pressing block 102 has second grooves 4 corresponding to the first grooves, and two ends of the first elastic member 105 are respectively embedded in the first grooves and the second grooves 4.
Similarly, as shown in fig. 5, the lower die base 20 includes a lower die plate 203 and a positioning base fixing plate 202, and the positioning base fixing plate 202 is fixed on the lower die plate 203 at a position corresponding to the positioning base 201. The upper surface of the positioning seat fixing plate 202 is provided with a third groove 5, the lower surface of the positioning seat 201 is provided with a fourth groove, and two ends of the second elastic member 204 are respectively embedded in the third groove 5 and the fourth groove.

As shown in fig. 6 to 9, the fixing frame 700 includes a frame 701 having a receiving cavity and a mounting plate 702 suspended below the lower die base, the frame 701 is used for providing a position for mounting the rod mill 301, the transmission assembly 600 and even the second driving mechanism 500.
As shown in fig. 6, the rod mill 301 is provided with a limiting protrusion 7, and both ends of the third elastic member 302 are pressed between the limiting protrusion 7 and the fixing frame 700. That is, the third elastic member 302 is supported between the stopper protrusion 7 and the mounting plate 702 at both ends. Preferably, the limiting protrusion 7 is located above the mounting plate 702, the mounting plate 702 is provided with a fifth groove, and the third elastic element 302 is embedded in the fifth groove.
Preferably, the second driving mechanism 500 is a pneumatic motor, and the output shaft of the pneumatic motor is transverse. The pneumatic motor is fixed on the side wall of the frame 701, and the output end of the pneumatic motor transversely penetrates into the side wall of the frame 701.
Unlike the multi-axis tool, the driving unit 600 in the present embodiment is provided on the holder 700, and is a member connected to the rod mill 301. Therefore, the problem of line interference caused by adopting a flexible shaft for connection is avoided, the equipment is more compact, and the occupation of space is reduced. In addition, the manufacturing cost of the device is reduced by replacing the multi-axis device with a simpler transmission assembly 600.
Specifically, as shown in fig. 8-9, the transmission assembly 600 includes a main rotating shaft 61 and a plurality of auxiliary rotating shafts 62 parallel to each other, and a transmission gear set; the rod-shaped milling cutter 301 is inserted on the secondary rotating shaft 62 and synchronously rotates along with the secondary rotating shaft; the transmission gear set comprises a first bevel gear Y1 positioned on the second driving mechanism 500, a second bevel gear Y2 sleeved outside the main rotating shaft 61, a main driving wheel Y3 and a driven driving wheel Y4 sleeved on each driven rotating shaft 62; the first bevel gear Y1 is meshed with the second bevel gear Y2, a plurality of the slave driving wheels Y4 are meshed successively and adjacently, and the master driving wheel Y3 is meshed with one of the slave driving wheels Y4.

Through a plurality of bar-shaped milling cutter 301 of transmission assembly 600 simultaneous drive, can realize getting rid of when a plurality of drill way burrs or surface burr structures such as ejector pin are constructed, equipment structure is simple, and production efficiency is high.
Preferably, a square hole is formed in the slave rotating shaft 62, the lower section of the rod-shaped milling cutter 301 is in a square column shape, and the plane of the square column shape is matched with the plane of the square hole, so that the relative rotation of the rod-shaped milling cutter 301 and the slave rotating shaft 62 is limited while the relative axial movement is realized, and further, the rod-shaped milling cutter 301 and the slave rotating shaft 62 rotate synchronously. Of course, the two parts can synchronously rotate and axially move relatively.
