Description

Technical Field

[0001] This application relates to the field of grinding equipment technology, and in particular to a grinding equipment for aluminum castings. Background Technology

[0002] Aluminum castings generally refer to aluminum workpieces produced through the casting process. After forming, aluminum castings often inevitably have some burrs on their edges. In actual processing, operators often need to manually remove these burrs using files or grinding equipment.

[0003] Chinese utility model patent CN221390332U discloses a grinding device for processing aluminum castings, including a frame for grinding aluminum castings and a protective cover disposed above the grinding assembly on the frame. The operator manually feeds the aluminum casting to be ground into the grinding assembly on the frame, and then manually grips the casting. The grinding assembly can grind away burrs on the edges of the aluminum casting. During this process, the protective cover can prevent upward-splashing debris generated during grinding.

[0004] However, the protective cover only blocks some of the upward-splashing debris from the aluminum castings during the grinding process. It cannot effectively block the debris that splashes outwards during the grinding process. Furthermore, the debris that splashes outwards can easily injure operators who are handling the aluminum castings around the equipment, posing a significant safety hazard. Utility Model Content

[0005] Purpose of the invention: This application provides an aluminum casting grinding device, which aims to improve the technical problem that the sputtering debris generated during the grinding process of aluminum castings is not easily blocked, resulting in a large safety hazard.

[0006] Technical Solution: This application provides an aluminum casting grinding device, including a frame on which a grinding component for grinding aluminum castings is disposed, and further including: a fixing base on which a fixing component for fixing the aluminum casting to be ground is disposed; a first baffle disposed on the fixing base and located on the side of the fixing component away from the grinding component to block debris splashed along a first direction; a second baffle movably disposed on the first baffle, the second baffle being movable above the fixing component and the grinding component to block debris splashed along a second direction; and two third baffles, the two third baffles being located on opposite sides of the first baffle, the third baffles being used to block debris splashed along a third direction and a fourth direction.

[0007] By adopting the above technical solution, the fixing base fixes the aluminum casting to be ground through the fixing component, reducing the phenomenon of accidental injury from splashed debris when manually holding the aluminum casting for grinding; the first baffle can block the debris splashed along the first direction, the second baffle can block the debris splashed along the second direction, and the third baffle can block the debris splashed along the third direction. At this time, the debris generated during the grinding of the aluminum casting can be effectively blocked and concentrated, reducing the phenomenon of debris splashing everywhere and easily causing accidental injury to the operator. In addition, it also helps the operator to quickly collect the debris, improving the efficiency of debris collection.

[0008] Furthermore, the aluminum casting grinding equipment also includes two sets of parallel linear motors, and the fixed base is fixed on the moving ends of the two sets of linear motors to move closer to or further away from the grinding assembly.

[0009] By adopting the above technical solution, the linear motor can quickly, stably and accurately approach or move away from the grinding component by carrying the fixed base at the moving end, which improves the convenience of grinding aluminum castings. In addition, it helps to control the problem of debris splashing around by adjusting the distance between the first baffle, the second baffle, the third baffle and the grinding component, and improves the convenience of collecting debris.

[0010] Furthermore, the retaining assembly includes pressure cylinders symmetrically arranged on the first baffle and pressure plates disposed on the output ends of all the pressure cylinders; after the aluminum casting is placed on the retaining base, the pressure cylinders can extend their output ends so that the pressure plates position the aluminum casting on the retaining base.

[0011] By adopting the above technical solution, the aluminum casting can be pressed firmly against the fixed base after the output end of the pressure cylinder is extended, which ensures the positioning stability of the aluminum casting, reduces the processing risk, and reduces the phenomenon of large-scale scattering of debris caused by unstable positioning of the aluminum casting.

[0012] Furthermore, the fixing base is also vertically provided with a directional rod, and the pressure plate is provided with a directional channel for the directional rod to fit through.

[0013] By adopting the above technical solution, the directional rod passing through the directional channel can provide lateral support to the pressure plate, which helps to ensure the positional stability of the pressure plate pressing the aluminum casting against the fixed base, and helps to reduce the phenomenon of large-scale scattering of debris caused by unstable positioning of the aluminum casting.

[0014] Furthermore, the second baffle is moved or positioned on the first baffle by an adjusting assembly, wherein the adjusting assembly includes an adjusting cylinder passing through the first baffle and a fixing plate fixed to the output end of the adjusting cylinder; the first baffle is also provided with a guide channel through which the second baffle can be adapted to pass, the guide channel being located below the adjusting cylinder; and the fixing plate is fixedly connected to the second baffle.

[0015] By adopting the above technical solution, after the cylinder extends outward and outputs, the second baffle, which is fixedly connected to the connecting plate, can move within the guide channel and move directly above the grinding assembly, thereby blocking the debris splashed along the second direction and reducing the phenomenon of debris splashing outward and accidentally injuring the operator.

[0016] Furthermore, the two third baffles and the first baffle together form an inverted region on the retaining base.

[0017] By adopting the above technical solution, the two third baffles and the first baffle together form an incline area, which can increase the protection against debris and reduce the risk of debris passing through the gap between the third baffle and the first baffle. In addition, the blocked debris can be confined within the incline area, which facilitates the subsequent collection of debris.

[0018] Furthermore, the third baffle is provided with a cavity, and the side wall of the third baffle facing the fixation component is provided with a ventilation channel that can communicate with the cavity; the side wall of the third baffle away from the fixation component is also provided with a duct, one end of which communicates with the cavity and the other end is connected to a suction component; the suction component can form a negative pressure adsorption space at the side wall of the third baffle where the ventilation channel is provided through the duct to adsorb debris entering the C-shaped area.

[0019] By adopting the above technical solution, after the suction component forms a negative pressure adsorption space at the ventilation channel through the air guide pipe, the debris entering the U-shaped area can be adsorbed by the negative pressure adsorption space, which helps to reduce the problem of debris splashing everywhere, and makes it easier for operators to quickly collect debris for cleaning.

[0020] Furthermore, the side wall of the third baffle is provided with a breathable adhesive membrane for adhering debris, and the breathable adhesive membrane is detachably covered on all the ventilation channels by bolts.

[0021] By adopting the above technical solution, the breathable membrane can be easily replaced after collecting debris, which improves the convenience and efficiency of operators in collecting and cleaning debris.

[0022] In summary, this application has at least the following beneficial technical effects:

[0023] The retaining base secures the aluminum casting to be ground using retaining components, reducing the risk of accidental injury from sputtered debris when manually holding the aluminum casting for grinding. The first baffle blocks debris splashed along the first direction, the second baffle blocks debris splashed along the second direction, and the third baffle blocks debris splashed along the third direction. In this way, the debris generated during the grinding process of the aluminum casting can be effectively blocked and concentrated, reducing the risk of debris splashing everywhere and causing accidental injury to the operator. In addition, it also helps the operator to quickly collect the debris, improving the efficiency of debris collection. Attached Figure Description

[0031] This application discloses an aluminum casting grinding device.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] Reference Figure 1A grinding device for aluminum castings includes a frame 1. A grinding component 11 is provided on the frame 1. After the operator places the aluminum casting to be ground on the grinding component 11, the grinding component 11 can grind the burrs on the edge of the aluminum casting.

[0034] Reference Figure 1 An aluminum casting grinding device also includes a fixed base 2 and two sets of parallel linear motors 3. The two sets of linear motors 3 are parallel to each other and fixed to the frame 1 with bolts. The extension direction of the linear motors 3 is perpendicular to the extension direction of the grinding component 11. The fixed base 2 is simultaneously fixed to the moving ends of the two sets of linear motors 3 with bolts, thereby enabling the fixed base 2 to quickly and accurately approach or move away from the grinding component 11.

[0035] Reference Figure 2 The top wall of the retaining base 2 is provided with a retaining component 4 and a first baffle 5. The first baffle 5 is vertically welded to the middle of the retaining base 2, and the end of the first baffle 5 away from the retaining base 2 is located above the grinding component 11. The retaining component 4 is located between the first baffle 5 and the grinding component 11, and the retaining component 4 is used to fix the aluminum casting on the retaining base 2.

[0036] Reference Figure 2 The retaining component 4 includes a pressing cylinder 41 and a pressing plate 42. In this embodiment, the number of pressing cylinders 41 can be two sets. The two sets of pressing cylinders 41 are symmetrically fixed to the side wall of the first baffle 5 facing the grinding component 11 by bolts, and the output ends of the two sets of pressing cylinders 41 face the retaining base 2.

[0037] Reference Figure 2 The number of pressure plates 42 can be one, and the pressure plate 42 is welded horizontally to the output end of the two sets of pressure cylinders 41. There is a gap between the pressure plate 42 and the fixed base 2. When the output end of the pressure cylinder 41 is in the retracted state, the operator can place the aluminum casting between the fixed base 2 and the pressure plate 42. At this time, the end of the aluminum casting away from the first baffle 5, that is, the end of the aluminum casting to be ground, is located outside the fixed base 2.

[0038] Reference Figure 2 After the pressure cylinder 41 extends its output end, the pressure plate 42 presses the aluminum casting against the fixed base 2. Then, after the linear motor 3 moves the fixed base 2 and brings the aluminum casting closer to the grinding assembly 11, the grinding assembly 11 can stably grind the aluminum casting. During the grinding process of the grinding assembly 11, the direction of movement from the grinding assembly 11 to the first baffle 5 is the first direction X. The debris splashed along the first direction X can be blocked by the first baffle 5.

[0039] Reference Figure 3To ensure the positional stability of the pressure plate 42 pressing the aluminum casting against the retaining base 2, a directional rod 21 is vertically welded to the top wall of the retaining base 2. There can be two directional rods 21. A directional channel 421 with an inner diameter matching the outer circumference of the directional rod 21 is provided through the pressure plate 42. Two directional channels 421 are provided, with one directional rod 21 passing through one directional channel 421. The directional rods 21 passing through the pressure plate 42 provide lateral support to the pressure plate 42, thus helping to improve the positional stability of the pressure plate 42 in fixing the aluminum casting to the retaining base 2.

[0040] Reference Figure 3 A guide channel 51 is horizontally provided on the first baffle 5, and the guide channel 51 is located above the grinding assembly 11. A second baffle 6 is slidably provided on the first baffle 5 through the guide channel 51, and an adjustment assembly 7 for controlling the movement and positioning of the second baffle 6 is also provided on the first baffle 5.

[0041] Reference Figure 3 The adjustment assembly 7 includes an adjustment cylinder 71 and a fixing plate 72. The adjustment cylinder 71 is horizontally welded to the first baffle 5 and passes through the first baffle 5, located above the guide channel 51. The fixing plate 72 is vertically welded to the output end of the adjustment cylinder 71, and the outer circumferential dimension of the fixing plate 72 is larger than the outer diameter of the output end of the adjustment cylinder 71.

[0042] Reference Figure 3 One end of the fixing plate 72 near the second baffle 6 is welded to the side wall of the second baffle 6. When the output end of the adjusting cylinder 71 is in the retracted state, the second baffle 6 is located directly above the fixing base 2. When the linear motor 3 delivers the aluminum casting to the grinding assembly 11, the adjusting cylinder 71 can extend its output end to move the second baffle 6 directly above the grinding assembly 11. During the grinding process of the grinding assembly 11 grinding the aluminum casting, the direction of movement from the grinding assembly 11 to the second baffle 6 is defined as the second direction Y, and the debris splashed along the second direction Y can be blocked by the second baffle 6.

[0043] Reference Figure 4A grinding device for aluminum castings also includes two third baffles 8, which are vertically welded to a fixed base 2. The two third baffles 8 are parallel to each other and located on opposite sides of a first baffle 5. Furthermore, the two third baffles 8 and the first baffle 5 form an inverted U-shaped region 9 on the fixed base 2. In this embodiment, the direction of movement along the extension of the grinding assembly 11, i.e., the direction between the two third baffles 8, is defined as the third direction Z. The third baffles 8 can block debris splashed along the third direction Z. Moreover, after the first baffle 5, the second baffle 6, and the third baffle 8 block the debris, the debris can be confined within the inverted U-shaped region 9, reducing the possibility of debris splashing everywhere and accidentally injuring operators.

[0044] Reference Figure 4 and Figure 5 To reduce the risk of debris splashing outwards through the U-shaped area 9 and injuring operators, a cavity 81 is pre-set inside the third baffle 8. Ventilation channels 82 are respectively provided on the sidewalls of the two third baffles 8 facing each other, and the ventilation channels 82 communicate with the cavity 81. An air guide pipe 83 is also provided on the sidewall of the third baffle 8 away from the ventilation channel 82. One end of the air guide pipe 83 communicates with the cavity 81, and the other end is connected to a suction component 84. In this embodiment, the suction component 84 can be a negative pressure suction pump, and the suction component 84 is fixed to the fixed base 2 by bolts.

[0045] Reference Figure 4 and Figure 5 The suction component 84 can draw air from the cavity 81 and the ventilation channel 82 through the air guide pipe 83, thereby forming a negative pressure adsorption space on the side wall of the third baffle 8 where the ventilation channel 82 is located. Debris entering the C-shaped region 9 can be adsorbed by the negative pressure in the negative pressure adsorption space, thereby effectively reducing the phenomenon of debris splashing outward through the C-shaped region 9.

[0046] Reference Figure 4 To improve the ease of debris collection, a breathable membrane 85 is detachably mounted on the side wall of the third baffle 8, which has ventilation channels 82, via bolts. In this embodiment, the breathable membrane 85 has high air permeability and is coated with adhesive that can bond metal debris. After the debris is adsorbed by the negative pressure adsorption space, it can be quickly adhered and fixed to the breathable membrane 85. At this time, most of the debris entering the U-shaped area 9 can be concentrated at the two third baffles 8, and the operator only needs to replace the breathable membrane 85 to achieve rapid collection and cleaning of debris.

[0047] The implementation principle of an aluminum casting grinding device according to an embodiment of this application is as follows: after the aluminum casting to be ground is placed between the pressure plate 42 and the fixed base 2, the pressure cylinder 41 extends its output end to press the aluminum casting against the fixed base 2.

[0048] The moving end of the linear motor 3 carries the fixed base 2 close to the grinding assembly 11, enabling the grinding assembly 11 to grind the positioned aluminum casting. During this process, the extended output end of the adjusting cylinder 71 allows the second baffle 6 to block the debris splashed upward along the second direction Y directly above the grinding assembly 11. The debris blocked by the second baffle 6 can fall back into the U-shaped area 9 under the action of gravity.

[0049] Within the U-shaped region 9, the first baffle 5 blocks debris splashed along the first direction X, and the third baffle 8 blocks debris splashed along the third direction Z. Debris entering the U-shaped region 9 is then adsorbed by the negative pressure adsorption space within the U-shaped region 9, and thus concentrated and positioned on the breathable membrane 85. This process greatly reduces the phenomenon of debris splashing around and accidentally injuring operators, and also improves the convenience and efficiency of debris collection.

[0050] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
