Description

Technical Field

[0001] This utility model relates to the field of punching device technology, and in particular to a positioning punching device for aluminum alloy castings. Background Technology

[0002] In the field of machining, positioning and punching devices are crucial equipment in the processing of aluminum alloy castings. They enable precise positioning and efficient punching of aluminum alloy castings, ensuring machining accuracy and product quality. However, existing positioning and punching devices typically have a fixed structure and often use a single downward punching direction. This design makes it difficult to flexibly adjust the punching angle when dealing with aluminum alloy castings of different shapes, sizes, and with specific angle requirements. In the mass production of aluminum alloy brackets with multiple angle hole positions, operators need to frequently change molds, readjust equipment, and even repeatedly clamp and adjust the position of the castings. This not only increases the complexity of operation but also wastes a significant amount of time, leading to a substantial extension of the production cycle. Therefore, this utility model proposes a positioning and punching device for aluminum alloy castings. Utility Model Content

[0003] The purpose of this invention is to address the problem that existing positioning punching devices in the background technology typically have a fixed structure and mostly use a single downward direction for punching. This structural design makes it difficult to flexibly adjust the punching angle when dealing with aluminum alloy castings of different shapes, sizes, and with special angle requirements. In the mass production of aluminum alloy brackets with multiple angle hole requirements, operators need to frequently change molds, readjust equipment, and even clamp and adjust the position of the castings multiple times. This not only increases the complexity of operation but also wastes a lot of time, resulting in a significant extension of the production cycle. Therefore, this invention proposes a positioning punching device for aluminum alloy castings.

[0004] The technical solution of this utility model is as follows: A positioning and punching device for aluminum alloy castings, comprising: a support base for support, a support plate fixedly disposed on the upper end of the support base, a guide groove opened on the side of the support plate, and a sleeve ring movably sleeved inside the guide groove; a limiting bolt threaded through the sleeve ring, one end of the limiting bolt being rotatably connected to a limiting block, and the limiting block being located inside the guide groove; a fixing block fixedly disposed on the outer wall of the sleeve ring, and a punching assembly for punching the aluminum alloy castings fixedly disposed on the upper surface of the fixing block; and a positioning assembly for limiting the aluminum alloy castings disposed on the upper surface of the support plate.

[0005] Optionally, the punching assembly includes a guide frame, the outer wall of which is provided with a guide groove, and two through grooves are provided on both sides of the guide frame, which are connected to the guide groove. A guide block is slidably disposed inside the guide groove, and a cylinder is fixedly mounted on the guide block. The output end of the cylinder passes through the guide block and extends to connect to a connecting block. A punch is provided at the output end of the connecting block. Limiting screws are fixedly disposed on both sides of the through groove, and limiting nuts are threaded onto the outer wall of the limiting screws.

[0006] Optionally, the positioning component includes a set of fixing plates fixedly disposed on the upper surface of the support plate, wherein an adjusting bolt is threaded through the fixing plate, and one end of the adjusting bolt is rotatably connected to the positioning plate.

[0007] Optionally, the inner wall of the guide groove is provided with multiple slots, and a locking block is fixedly provided at one end of the limiting block.

[0008] Optionally, the upper surface of the support plate is provided with an angle mark.

[0009] Optionally, the output end of the connecting block is connected to the punch via a punch holder.

[0010] Optionally, a guide block is fixedly sleeved on the outer wall of the limiting screw, and the guide block is slidably connected to the through groove.

[0011] Optionally, the positioning plate is configured with an arc-shaped structure.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This utility model utilizes a sliding fit structure between the guide groove and the guide block in the punching assembly, and limits the guide block with limiting bolts and limiting nuts, allowing the guide block to slide freely within the guide groove. This drives the cylinder, connecting block, and punch to move, enabling the punch to adjust the punching angle according to the different shapes and hole requirements of aluminum alloy castings. Without the need for equipment readjustment, it can quickly adapt to the punching angle requirements of different castings, effectively improving production efficiency.

[0014] Furthermore, this utility model utilizes the guide groove and the matching limiting bolt and limiting block of the sleeve ring. During the movement of the sleeve ring, it drives the punching assembly fixed on its outer wall fixing block to move. The limiting bolt and limiting block are positioned after the direction is adjusted. It can conveniently adjust the punching position according to the different shapes, sizes and punching requirements of aluminum alloy castings, improve the versatility and applicability of the device, effectively shorten the production preparation time and improve production efficiency.

[0029] Example

[0030] like Figure 1 and Figure 2 As shown, the present invention proposes an aluminum alloy casting positioning punching device, comprising: a support base 1 for support, a support plate 2 fixedly provided on the upper end of the support base 1, which can provide stable support for the support plate 2, an angle mark 12 provided on the upper surface of the support plate 2, and the angle mark 12 is 360 degrees, which facilitates observation of the punching adjustment position, a guide groove 3 opened on the side of the support plate 2, a plurality of slots 10 opened on the inner wall of the guide groove 3, and a sleeve ring 4 movably sleeved inside the guide groove 3, which can limit the position of the sleeve ring 4 and ensure the stable rotation of the sleeve ring 4.

[0031] Furthermore, a limiting bolt 5 is threaded through the sleeve ring 4, and one end of the limiting bolt 5 is rotatably connected to a limiting block 6. The limiting bolt 5 can adjust the friction force between the limiting block 6 and the guide groove 3, thereby limiting or adjusting the sleeve ring 4. The limiting block 6 is located inside the guide groove 3, and a locking block 11 is fixedly provided at one end of the limiting block 6. The locking block 11 can engage with the locking groove 10 opened on the inner wall of the guide groove 3, thereby increasing the stability of limiting the sleeve ring 4. The fixing block 7 fixedly provided on the outer wall of the sleeve ring 4 can drive the punching assembly 8 on the fixing block 7 to move.

[0032] like Figure 3As shown, a punching assembly 8 for punching aluminum alloy castings is fixedly installed on the upper surface of the fixed block 7. The punching assembly 8 includes a guide frame 81, which is arc-shaped, allowing the punch 87 to move according to the direction of the guide frame 81. A guide groove 82 is provided on the outer wall of the guide frame 81, and grooves 83 are provided on both sides of the guide frame 81, which are connected to the guide groove 82. A guide block 84 is slidably installed inside the guide groove 82, which guides the guide block 84 and allows it to move according to the guide groove 82. A cylinder 85 is fixedly installed on the guide block 84, which provides pressure to the punch 87 to punch the aluminum alloy castings. The output end of the cylinder 85 passes through the guide block 84 and extends to connect to a connecting block 86. The output end of the connecting block 86 is connected to the punch 87 through the punch seat 13, which can drive the punch 87 to move according to the guide frame 81, thereby quickly adjusting the punching angle of the punch 87.

[0033] Furthermore, the output end of the connecting block 86 is provided with a punch 87, and limit screws 88 are fixedly provided on both sides of the through groove 83. A guide block 14 is fixedly sleeved on the outer wall of the limit screw 88. The guide block 14 is slidably connected to the through groove 83 to ensure the stability of the movement of the limit screw 88. A limit nut 89 is threaded on the outer wall of the limit screw 88 to stably limit the guide block 84, ensure the stability of the punching, and improve the punching quality.

[0034] like Figure 1 and Figure 4 As shown, the upper surface of the support plate 2 is provided with a positioning component 9 for limiting the aluminum alloy casting. The positioning component 9 includes a set of fixing plates 91 fixedly disposed on the upper surface of the support plate 2. An adjusting bolt 92 is threaded through the fixing plate 91. One end of the adjusting bolt 92 is rotatably connected to the positioning plate 93 through a bearing, which can drive the positioning plate 93 to clamp and position the aluminum alloy casting. The positioning plate 93 is designed with an arc shape, which can better fit the surface of the casting and ensure the stability of the positioning.

[0035] The working principle of this embodiment is as follows: the aluminum alloy casting is placed between the positioning plates 93, and the adjusting bolt 92 on the fixing plate 91 in the positioning assembly 9 is rotated. The adjusting bolt 92 drives the positioning plate 93 to move, and the positioning plate 93 clamps and limits the casting. Since the positioning plate 93 is set with an arc structure, it can better fit the surface of the casting and ensure the stability of the positioning.

[0036] After positioning, adjust the position and angle of the punching assembly 8 according to the punching requirements. First, loosen the limiting bolt 5 on the threaded through-hole sleeve 4. At this time, the sleeve 4 can move freely in the guide groove 3. By pushing the fixing block 7, the sleeve 4 is moved to slide in the guide groove 3, adjusting the horizontal position of the punching assembly 8. At the same time, according to the angle mark 12 set on the upper surface of the support plate 2, rotate the sleeve 4 to make the punching assembly 8 reach the required position. After determining the position and angle, tighten the limiting bolt 5. The limiting bolt 5 drives the limiting block 6 to move. The locking block 11 at one end of the limiting block 6 will lock into the locking groove 10 on the inner wall of the guide groove 3, achieving a stable fixation.

[0037] Next, adjust the angle of the punch 87. In the punching assembly 8, loosen the limiting nut 89 and slide the guide block 84 in the guide groove 82, driving the cylinder 85, connecting block 86 and punch 87 to move. After adjusting to the appropriate punching angle, tighten the limiting nut 89 to fix the guide block 84 tightly against both sides of the guide frame 81. At this time, the guide block 14 fixedly sleeved on the outer wall of the limiting screw 88 slides in the groove 83, playing a guiding and stabilizing role.

[0038] Finally, the punching operation is performed. The cylinder 85 is activated, and its output pushes the connecting block 86. The connecting block 86, through the punch holder 13, moves the punch 87 downwards to punch the positioned aluminum alloy casting. After one punching operation, the cylinder 85 retracts. To punch in other locations, repeat the steps above to adjust the position and angle.

[0039] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
