Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy casting processing technology, specifically to a drilling device for precision aluminum alloy castings. Background Technology

[0002] Drilling holes in aluminum alloy castings is a common process in aluminum alloy casting manufacturing. It usually involves creating holes in the aluminum alloy castings through the rotating cutting action of a drill bit, and is the most widely used drilling method in mechanical drilling.

[0003] According to Chinese Patent Publication No. CN217529279U, "A High-Efficiency Drilling Device for Aluminum Alloy Castings," the device primarily utilizes the interaction between a drill bit, a support column, a motor, a pulley, and a transmission belt. Starting the motor causes its output shaft to rotate the drill bit, and the support column is manually pulled downwards, effectively drilling holes in the casting. This avoids accidental hand injuries from bricks, improving safety and production quality to a certain extent. Furthermore, the device employs a push block, a fixed block, a one-way gear, a full gear, and a second rack. The rotation of the one-way gear drives the rotating rod, which in turn drives the full gear, causing it to mesh with the second rack. This, in turn, moves the push block backwards, pushing the casting and facilitating subsequent collection.

[0004] Common aluminum alloy castings can be drilled by mechanical drilling. Some aluminum alloy castings require deep hole machining. When the hole diameter and depth reach more than 50mm, chips will accumulate in the hole, resulting in poor chip removal, which in turn causes the drill bit to become clogged and break, affecting the machining efficiency.

[0005] Therefore, a drilling device for precision aluminum alloy castings is proposed to solve the problem that machining debris accumulates at the bottom of the hole during deep hole machining of some aluminum alloy castings, resulting in poor chip removal. Utility Model Content

[0006] The technical problem to be solved by this utility model is that when some aluminum alloy castings are deep-hole processed, the processing chips will accumulate on the bottom side of the hole, resulting in poor chip removal. Therefore, a drilling device for precision aluminum alloy castings is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a drilling device for precision aluminum alloy castings, including legs and a fixing plate. A placement groove is formed through the fixing plate, and pads are fixedly connected to both sides of the placement groove. Electric push rods are fixedly connected to both sides of the fixing plate located in the placement groove. A clamping plate is fixedly connected to the output end of the electric push rod. A limit groove is formed at the center of the clamping plate. An adjusting rod is rotatably connected to the clamping plate within the limit groove. A pressure plate is threadedly connected to the adjusting rod within the limit groove. Support plates are fixedly connected to the four sides of the bottom end of the fixing plate. A first motor is fixedly connected to two of the support plates. A first screw is fixedly connected to the output end of the first motor. A first sliding plate is threadedly connected to the first screw. A second motor is fixedly connected to the slide plate. A second screw is fixedly connected to the output end of the second motor. A second slide plate is threaded onto the second screw. An electric telescopic rod is fixedly connected to the upper end of the second slide plate. A moving frame is fixedly connected to the upper end of the electric telescopic rod. A third motor is fixedly connected inside the moving frame. A drill rod is fixedly connected to the output end of the third motor. A spring rod is inserted into the moving frame.

The monitor is connected in series with a display screen via wires. The display screen is fixedly connected to the upper end of the fixed plate.

[0008] As a preferred technical solution of this utility model, a stop block is fixedly connected to the upper side of the water distribution ring. The stop block corresponds to the fixed plate. By setting the stop block, the direct collision between the water distribution ring and the fixed plate can be reduced.

[0009] As a preferred technical solution of this utility model, the fixing plate is fixedly connected to hydraulic push rods on both sides of the placement groove. The output end of the hydraulic push rod is located between the two clamping plates. By setting the hydraulic push rod, in conjunction with the electric push rod, the casting can be stably limited.

[0010] As a preferred technical solution of this utility model, folding baffles are fixedly connected to both sides of the first and second sliding plates. The folding baffles are respectively sleeved on the first and second screws. By setting the folding baffles, the contact of drilling debris or cutting fluid with the first or second screw can be reduced, and the rotational stiffness of the first and second screws can be reduced.

[0011] As a preferred technical solution of this utility model, both the first screw and the second screw are provided with auxiliary rods. The auxiliary rods are respectively inserted into the first slide plate and the second slide plate. The auxiliary rods are in contact with the folding cover. By providing auxiliary rods, the folding cover can be limited, reducing the contact between the folding cover and the first screw or the second screw.

[0012] This utility model has the following advantages: it provides a limit for the casting by using an electric push rod, a hydraulic push rod, a clamping plate, and a pressure plate; then, a second sliding plate that can move laterally and longitudinally is set on the bottom side of the fixed plate; and the electric telescopic rod and a third motor drive the drill rod to drill holes in the casting.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3The device shown is a precision aluminum alloy casting drilling machine, including a support leg and a fixed plate 1. A placement groove 2 runs through the fixed plate 1 for placing the casting. Pads 3 are fixedly connected to both sides of the placement groove 2. Electric push rods 4 are fixedly connected to both sides of the fixed plate 1 in the placement groove 2. The extension of the electric push rods 4 causes a clamping plate 5 to move relative to the casting. The L-shaped structure of the clamping plate 5 limits the casting on both sides. Then, in conjunction with a hydraulic push rod 21, a pressure plate 7 further limits the casting on the upper side, improving the stability of the casting. The output end of the electric push rod 4 is fixedly connected to the clamping plate 5. A limit groove is formed in the center of the clamping plate 5. An adjusting rod 6 is rotatably connected within the limiting groove. Rotating the adjusting rod 6 causes the pressure plate 7 to move downwards. The adjusting rod 6 is threadedly connected to the pressure plate 7 within the limiting groove. Support plates 8 are fixedly connected to all four sides of the bottom end of the fixed plate 1. A first motor is fixedly connected to two of the support plates 8. The first motor drives the first screw 9 to rotate, causing the first slide plate 10 to move laterally. A second motor drives the second screw 11 to rotate, causing the second slide plate 12 to move longitudinally. The output end of the first motor is fixedly connected to the first screw 9, and the first slide plate 10 is threadedly connected to the first screw 9. A second motor is fixedly connected to one of the first slide plates 10. The output of the second motor... A second screw 11 is fixedly connected to the end of the fixed plate 14. A second sliding plate 12 is threaded onto the second screw 11. An electric telescopic rod 13 is fixedly connected to the upper end of the second sliding plate 12. The electric telescopic rod 13 controls the upward movement of the moving frame 14. With the cooperation of the first screw 9 and the second screw 11, the moving frame 14 and the drill rod 15 can achieve three-dimensional movement in the space under the fixed plate 1. The moving frame 14 is fixedly connected to the upper end of the electric telescopic rod 13. A third motor is fixedly connected inside the moving frame 14. The drill rod 15 is fixedly connected to the output end of the third motor. A spring rod 16 is inserted into the moving frame 14. A water-dividing ring 17 is fixedly connected to the upper end of the spring rod 16. A water inlet hose is fixedly connected to one side of the 17. An external pump draws water or coolant from the outside and sprays it through the water inlet hose. The water is then sprayed through the water distribution ring 17 and the L-shaped nozzle 18 to the drilling site to wash away the debris. An L-shaped nozzle 18 is fixedly connected inside the water distribution ring 17. One end of the L-shaped nozzle 18 corresponds to the fixed plate 1. A monitor is fixedly connected to one of the support plates 8. The monitor is connected in series with a display screen 19 via wires. The display screen 19 is fixedly connected to the upper end of the fixed plate 1. The monitor monitors the drilling site and provides feedback through the display screen 19. By inverting the casting to be drilled, the retention of cutting debris in the drilling site can be reduced by gravity.

[0019] Among them, a stop block 20 is fixedly connected to the upper side of the water distribution ring 17. The stop block 20 corresponds to the fixed plate 1. By setting the stop block 20, which is made of rubber material, the direct collision between the water distribution ring 17 and the fixed plate 1 can be reduced.

[0020] The fixed plate 1 is located in the placement groove 2 and is fixedly connected to hydraulic push rods 21 on both sides. The output end of the hydraulic push rod 21 is located between the two clamping plates 5. By setting the hydraulic push rod 21, the limiting effect on the casting can be increased.

[0021] The first slide plate 10 and the second slide plate 12 are fixedly connected to both sides with folding covers 22. The folding covers 22 are respectively sleeved on the first screw 9 and the second screw 11. The folding covers 22 can prevent cutting debris from contacting the first screw 9 or the second screw 11, thereby reducing the movement sluggishness of the first slide plate 10 and the second slide plate 12.

[0022] Both the first screw 9 and the second screw 11 are provided with auxiliary rods 23. The auxiliary rods 23 are respectively inserted into the first slide plate 10 and the second slide plate 12. The auxiliary rods 23 are in contact with the folding cover 22. By setting the auxiliary rods 23 on the upper and lower sides of the screw, the folding cover 22 can be supported, reducing the contact between the folding cover 22 and the screw.

[0023] The models used for the first motor, second motor, third motor, electric push rod 4, hydraulic push rod 21 and electric telescopic rod 13 can all be purchased from the market, and the internal execution program is built into the equipment.

[0024] Working principle: The casting is placed in the placement groove 2. The electric push rod 4 and hydraulic push rod 21 extend and, together with the L-shaped clamping plate 5 and pressure plate 7, limit the casting and gradually position it in the center of the placement groove 2. Then, the situation at the drilling point is observed through the display screen 19. When drilling is required, the first motor and the second motor can be started, driving the first screw 9 and the second screw 11 to rotate. This causes the drill rod 15 to correspond to the position to be drilled on the casting. Then, the third motor drives the drill rod 15 to rotate, and at the same time, the electric telescopic rod 13 extends to perform the drilling operation.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0026] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
