Description

Technical Field

[0001] The utility model belongs to the technical field of metal die-casting part processing equipment, and particularly relates to an automatic burr scraping machine for the edges of metal die-castings. Background Art

[0002] When metal die-castings are produced, a lot of burrs will be generated on their surfaces. Burrs are a relatively common product defect, which not only affect the appearance but also pose a risk of accidentally injuring workers. Therefore, it is necessary to remove the burrs of metal die-castings to ensure that the edges of metal die-castings are smooth and round.

[0003] Among them, some burrs are at the edges of metal die-castings. Since this position is not on a flat surface, if a traditional drill bit is used to remove them, it will inevitably directly damage the edges of metal die-castings and affect their original shapes, which urgently needs to be improved.

[0040] In the embodiments of the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage", "fixation" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0041] In one embodiment of the present utility model, as Figures 1 to 2 shown, an automatic burr scraping machine for the edge of a metal die casting is provided, which includes a frame 10, a positioning device 20, a scraping device 30, and a driving device 40. An avoidance hole 11 is formed in the frame 10. The positioning device 20 is used to position the metal die casting whose edge burr needs to be removed. The positioning device 20 is erected above the avoidance hole 11 and is slidably connected to the frame 10. The scraping device 30 is used to scrape the edge burr of the metal die casting. The scraping device 30 is installed on the side of the avoidance hole 11 and is perpendicular to the sliding direction of the positioning device 20 relative to the frame 10. The driving device 40 is used to drive the positioning device 20 to slide relative to the frame 10. The driving device 40 is installed at the bottom of the frame 10 and passes through the avoidance hole 11 and then is connected to the positioning device 20.

[0042] When the automatic burr scraping machine for the edge of a metal die casting provided by the embodiments of the present utility model works, the metal die casting whose edge burr needs to be scraped is fixed in the positioning device 20, and then the position of the scraping device 30 is adjusted so that it can scrape the metal die casting whose edge burr needs to be removed. Finally, the driving device 40 is started. The driving device 40 drives the positioning device 20 to move linearly back and forth. The positioning device 20 drives the metal die casting positioned by it to move linearly back and forth. During the moving process, it will pass through the scraping device 30. Through the scraping device 30, the edge burr of the metal die casting is scraped and cleaned, realizing the automatic removal of the edge burr of the metal die casting. It is particularly suitable for the edge burr that cannot be removed by a drill, and is efficient, reliable, and safe.

[0043] In one embodiment of the present utility model, as Figure 1 and 3As shown, the positioning device 20 includes a bottom plate 21, a first cylinder 22, a first positioning block 23, a second cylinder 24 and a second positioning block 25. The bottom plate 21 is mounted above the avoidance hole 11 through a slide rail 212. The bottom of the bottom plate 21 is connected to the output end of the driving device 40. A limiting block 211 for primary positioning of the metal die casting is provided on the bottom plate 21. The first cylinder 22 and the second cylinder 24 are respectively installed on the bottom plate 21 on opposite sides of the limiting block 211. Specifically, the bottom plate 21 serves as the support structure of the entire positioning device 20. The first cylinder 22 and the second cylinder 24 are distributed on both sides in the length direction of the bottom plate 21, and the length direction is also the moving direction of the bottom plate 21, which is also the X-axis direction. The first positioning block 23 and the second positioning block 25 are respectively connected to the first cylinder 22 and the second cylinder 24, so that the first positioning block 23 and the second positioning block 25 are driven by the first cylinder 22 and the second cylinder 24 respectively.

[0044] Further, as Figure 1 and 3 shown, the first positioning block 23 includes a first driving end 231, a first hinged end 232 and a first abutting end 233 arranged in a triangular shape. The first hinged end 232 is hinged to the bottom plate 21. The first driving end 231 is hinged to the piston rod of the first cylinder 22. Driven by the first cylinder 22, the first positioning block 23 rotates around the first hinged end 232 until the first abutting end 233 abuts against one side of the metal die casting initially positioned on the limiting block 211. By driving the first cylinder 22, the first positioning block 23 rotates around the hinge joint between its first hinged end 232 and the bottom plate 21, so that the first abutting end 233 of the first positioning block 23 realizes a swinging angle until it tightly abuts against one side of the metal die casting initially positioned on the limiting block 211.

[0045] Similarly, as Figure 1 and 3As shown, the second positioning block 25 includes a second driving end 251, a second hinged end 252, and a second abutting end 253 arranged in a triangle. The second hinged end 252 is hinged to the bottom plate 21, and the second driving end 251 is hinged to the piston rod of the second cylinder 24. Driven by the second cylinder 24, the second positioning block 25 rotates around the second hinged end 252 until the second abutting end 253 abuts against the other side of the metal die-casting initially positioned on the limiting block 211. By driving the second cylinder 24, the second positioning block 25 rotates around the hinge joint between its second hinged end 252 and the bottom plate 21, so that the second abutting end 253 of the second positioning block 25 realizes a swinging angle until it abuts tightly against the other side of the metal die-casting initially positioned on the limiting block 211. In this way, the metal die-casting is positioned at multiple positions. Thus, driven by the driving device 40, the bottom plate 21 and the metal die-casting thereon can move along the X-axis direction, and the edge flash of the moving metal die-casting will pass through the scraping device 30 arranged on the side, and the edge flash passing through the scraping device 30 is effectively removed.

[0046] In an embodiment of the present invention, as Figure 2 shown, the driving device 40 includes a driving cylinder 41 and a connecting block 42. The driving cylinder 41 is installed at the bottom of the frame 10 and is located below the avoidance hole 11. The bottom end of the connecting block 42 is connected to the piston rod of the driving cylinder 41, and the top end is connected to the bottom plate 21. Driven by the driving cylinder 41, the bottom plate 21 moves along the X-axis guided by the slide rail 212. Specifically, after the driving cylinder 41 is started, the movement of the connecting block 42 connected to it is driven by the telescopic movement of its piston rod. The connecting block 42 is also connected to the bottom plate 21, so that the movement of the connecting block 42 can be converted into the movement of the bottom plate 21. Then, the telescopic movement of the piston rod of the driving cylinder 41 can effectively control the reciprocating movement of the bottom plate 21 and the metal die-casting thereon along the X-axis.

[0047] In an embodiment of the present invention, as Figure 1 and 4As shown, the scraper device 30 includes a scraper 31, a scraper seat 32, a Z-axis moving mechanism 33, and a Y-axis moving mechanism 34. The Y-axis moving mechanism 34 is installed on the frame 10. The Z-axis moving mechanism 33 is connected to the output end of the Y-axis moving mechanism 34 and is driven by the Y-axis moving mechanism 34 to move along the Y-axis. The scraper seat 32 is connected to the output end of the Z-axis moving mechanism 33 and is driven by the Z-axis moving mechanism 33 to move along the Z-axis. The scraper 31 is horizontal and installed on the scraper seat 32 along the Y-axis direction. The end shape of the scraper 31 is adapted to the edge shape of the metal die casting. Specifically, the Y-axis moving mechanism 34 can control the Z-axis moving mechanism 33 connected thereto to move along the Y-axis, and the Z-axis moving mechanism 33 can control the scraper seat 32 connected thereto to move along the Z-axis. Thus, under the combined action of the Y-axis moving mechanism 34 and the Z-axis moving mechanism 33, the position of the scraper 31 can be adjusted in the Y-axis and Z-axis directions, so that it can be aligned with the edge flash position of the metal die casting positioned in the positioning device 20. In this way, when the driving device 40 drives the positioning device 20 to move along the X-axis, the edge flash of the metal die casting can pass through the blade of the scraper 31, thereby effectively removing the edge flash of the metal die casting.

[0048] In an embodiment of the present invention, as Figure 1 and 4 shown, the Y-axis moving mechanism 34 includes a Y-axis turntable 331, a Y-axis lead screw 332, a Y-axis slider 333, and a Y-axis guide rail 334. The Y-axis guide rail 334 is installed on the frame 10 along the Y-axis and is located on the side of the avoidance hole 11. The Y-axis slider 333 is slidably engaged with the Y-axis guide rail 334. The Y-axis lead screw 332 is rotatably installed on the Y-axis guide rail 334 and its end is fixedly connected to the Y-axis slider 333. The Y-axis turntable 331 is installed at the head end of the Y-axis lead screw 332. The Z-axis moving mechanism 33 is connected to the Y-axis slider 333. By rotating the Y-axis turntable 331, the Y-axis lead screw is driven to rotate. The rotation of the Y-axis lead screw 332 causes the Y-axis slider 333 connected thereto to move along the Y-axis guided by the Y-axis guide rail 334, thereby driving the movement of the entire Z-axis moving mechanism 33 in the Y-axis direction. The operation is convenient, simple, and efficient.

[0049] In an embodiment of the present invention, as Figure 1 and 4As shown, the Z-axis moving mechanism 33 includes a Z-axis turntable 341, a Z-axis lead screw 342, a Z-axis slider 343, and a Z-axis guide rail 344. The Z-axis guide rail 344 is arranged along the Z-axis and is connected to the Y-axis slider 333. The Z-axis slider 343 is slidably engaged with the Z-axis guide rail 344. The Z-axis lead screw 342 is rotatably mounted on the Z-axis guide rail 344 and its end is fixedly connected to the Z-axis slider 343. The Z-axis turntable 341 is mounted at the head end of the Z-axis lead screw 342. The blade holder 32 is connected to the side of the Z-axis slider 343. Specifically, by rotating the Z-axis turntable 341, the Z-axis lead screw is driven to rotate. The rotation of the Z-axis lead screw 342 causes the Z-axis slider 343 connected thereto to move along the Z-axis guided by the Z-axis guide rail 344. Thus, the entire blade holder 32 is driven to move along the Z-axis, and further the blade 31 is driven to move backward along the Z-axis. The operation is convenient, simple and efficient.

[0050] Preferably, as Figure 4 shown, the Z-axis guide rail 344 and the Y-axis slider 333 are integrally formed. In this way, the two can form a whole, and the installation is more convenient.

[0051] In an embodiment of the present invention, as Figure 1 shown, there are two blade devices 30, and the two blade devices 30 are symmetrically arranged on opposite sides of the positioning device 20. The blade devices 30 arranged symmetrically on both sides can effectively remove the edge flash on opposite sides of the metal die-casting.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
