Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a milling device for large precision sheet metal parts. Background Technology

[0002] After stamping and cutting, large sheet metal parts need to be milled, which is usually done at high speed using a dedicated milling machine.

[0003] During the milling process of large sheet metal parts, a large amount of metal chips are generated, and these chips can splatter from multiple directions depending on the milling position. Typical milling equipment uses a transparent enclosure to block the splattering chips, but the milling equipment itself is also contained within this enclosure. Therefore, prolonged exposure to splattering chips can damage the surface of the structure, potentially affecting the lifespan of the equipment. Utility Model Content

[0004] This utility model discloses a milling device for large precision sheet metal parts, which aims to solve the technical problem that long-term metal shavings can damage the surface of the structure and potentially affect the service life of the equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A large precision sheet metal milling device includes a limiting mechanism, a stabilizing mechanism disposed on one side of the limiting mechanism, an anti-splash mechanism disposed on the top of the limiting mechanism, a tool holder disposed in the middle of the anti-splash mechanism, a milling cutter mounted on the tool holder, and a multi-axis track connected to the tool holder.

[0007] The splash-proof mechanism includes an electromagnetic plate, a lower metal frame adsorbed on the top of the electromagnetic plate, a trapezoidal outer cover connected to the top of the lower metal frame, an elastic sealing sleeve connected to the outer cover and the knife holder, sliders disposed on both sides of the trapezoidal outer cover, and a linear guide rail for driving the sliders to move.

[0008] The top of the trapezoidal outer cover is fixedly connected to an upper frame, and the upper frame is connected to the bottom of the elastic sealing sleeve. An extension plate is fixedly connected to the outer walls of the opposite sides of the upper frame, and the slider is embedded in the extension plate.

[0009] By incorporating an anti-splash mechanism, a linear guide rail drives a slider to move up and down, causing the trapezoidal outer cover to move downwards before the milling operation. The position of the trapezoidal outer cover is stabilized by energizing an electromagnetic plate. Simultaneously, based on the setting of the elastic sealing sleeve, a barrier is established between the trapezoidal outer cover and the tool holder, which can block the splashing paths of metal chips from multiple directions during the milling process, allowing the metal chips to fall downwards and be collected smoothly. This avoids damage to the equipment surface caused by metal chip splashing and also prevents obstruction of the milling process.

[0010] In a preferred embodiment, a crossbeam is fixedly connected to the bottom end of the limiting mechanism and the linear guide rail, and the crossbeam is fixed to the top of the waste collection trough.

[0011] The limiting mechanism includes a bearing seat, a support plate, a clamp mounted on the top of the support plate, and a vibrator mounted on the bottom of the support plate.

[0012] Two bearing seats are provided, and the two bearing seats are respectively located on opposite sides of the support plate one, and a support shaft is provided in each of the two bearing seats;

[0013] Connecting seats are provided on opposite sides of the support plate one, and the opposite ends of the two support shafts are connected to the support plate one through the connecting seats. The other end of one of the support shafts is connected to a motor, and the motor is fixed outside the bearing seat.

[0014] By setting up a limiting mechanism, since the machined surface of the sheet metal part has a recessed area, the metal shavings generated during the processing will temporarily remain in the recessed area and are difficult to clean. In the limiting mechanism, the motor can drive the support plate to rotate through the support shaft, thereby providing a flipping function for the sheet metal part. The metal shavings remaining on the surface of the sheet metal part will fall into the waste collection tank under the action of gravity and the vibration of the vibrator, thus ensuring the thoroughness of metal shaving cleaning.

[0015] In a preferred embodiment, the stabilizing mechanism includes a cylinder, a U-shaped bracket connected to the cylinder, and an extension plate fixed to one side of the support plate.

[0016] One end of the extension plate 2 is provided with an angle, the U-shaped bracket is snapped onto the outside of the extension plate 2, and the inner wall of the U-shaped bracket is attached to the outer wall of the extension plate 2.

[0017] The cylinder includes an output rod, which is connected to a U-shaped bracket. A support frame is fixedly connected to the outside of the cylinder, and multiple limiting rods are movably inserted inside the support frame.

[0018] Multiple limiting rods are simultaneously connected to one side of the U-shaped bracket. The bottom end of the support frame is fixedly connected to a second support plate, and the top end of the second support plate is fixedly connected to multiple support seats. The top end of each support seat is attached to the outer wall of the limiting rod.

[0019] With a stabilizing mechanism, when the support plate is horizontal, the output rod is extended by the cylinder, which moves the U-shaped bracket closer to the extension plate. During the approach, the support plate can be corrected to ensure that it is in a completely horizontal state. The inner wall of the U-shaped bracket limits the extension plate, which can enhance the stability of the support plate and prevent the sheet metal parts from shaking during the milling process.

[0020] As described above, a large precision sheet metal milling device includes a limiting mechanism, a stabilizing mechanism disposed on one side of the limiting mechanism, an anti-splash mechanism disposed at the top of the limiting mechanism, a tool holder disposed in the middle of the anti-splash mechanism, a milling cutter mounted on the tool holder, and a multi-axis track connected to the tool holder. The anti-splash mechanism includes an electromagnetic plate, a lower metal frame adsorbed on the top of the electromagnetic plate, a trapezoidal outer cover connected to the top of the lower metal frame, an elastic sealing sleeve connected to the outer cover and the tool holder, sliders disposed on both sides of the trapezoidal outer cover, and a linear guide rail for driving the sliders to move. The large precision sheet metal milling device provided by this utility model has the technical effect of preventing metal chips from splashing and damaging the surface of the equipment, and also preventing obstruction of the milling process.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] The large precision sheet metal milling device disclosed in this utility model is mainly used in sheet metal milling scenarios.

[0028] Reference Figure 1 and Figure 2 A large precision sheet metal milling device includes a limiting mechanism 5, a stabilizing mechanism 7 disposed on one side of the limiting mechanism 5, an anti-splash mechanism 2 disposed at the top of the limiting mechanism 5, a tool holder 1 disposed in the middle of the anti-splash mechanism 2, a milling cutter 6 mounted on the tool holder 1, and a multi-axis track connected to the tool holder 1.

[0029] The anti-splash mechanism 2 includes an electromagnetic plate 207, a lower metal frame 206 adsorbed on the top of the electromagnetic plate 207, a trapezoidal outer cover 205 connected to the top of the lower metal frame 206, an elastic sealing sleeve 208 connected to the outer cover 205 and the tool holder 1, sliders 202 disposed on both sides of the trapezoidal outer cover 205, and a linear guide rail 201 that drives the sliders 202 to move. In the anti-splash mechanism 2, the sliders 202 are driven to move up and down by the linear guide rail 201, and the trapezoidal outer cover is moved before the milling operation. 205 moves downward and the electromagnetic plate 207 is energized, so that the electromagnetic plate 207 fits against the lower metal frame 206 to fix the position of the trapezoidal outer cover 205. At the same time, based on the setting of the elastic sealing sleeve 208, a shield is established between the trapezoidal outer cover 205 and the tool holder 1, thereby blocking the splashing path of metal chips that splash from multiple directions during the milling process, so that the metal chips can fall downward smoothly and be collected, thereby avoiding damage to the surface of the equipment during the splashing of metal chips, and also not obstructing the milling process.

[0030] Reference Figure 2 In a preferred embodiment, the top of the trapezoidal outer cover 205 is fixedly connected to an upper frame 204, and the upper frame 204 is connected to the bottom of the elastic sealing sleeve 208. The outer walls of the opposite sides of the upper frame 204 are respectively fixedly connected to extension plates 203, and the slider 202 is embedded in the extension plate 203.

[0031] Reference Figure 1 and Figure 2 In a preferred embodiment, the bottom end of the limiting mechanism 5 and the linear guide rail 201 is fixedly connected to a crossbeam 3, and the crossbeam 3 is fixed to the top of the waste collection trough 4.

[0032] Reference Figure 3In a preferred embodiment, the limiting mechanism 5 includes a bearing seat 501, a support plate 503, a clamp 507 mounted on the top of the support plate 503, and a vibrator 504 mounted on the bottom of the support plate 503.

[0033] Reference Figure 3 In a preferred embodiment, two bearing seats 501 are provided, and the two bearing seats 501 are respectively provided on opposite sides of the support plate 503, and the two bearing seats 501 are respectively provided with support shafts 505.

[0034] Reference Figure 3 In a preferred embodiment, connecting seats 502 are respectively provided on opposite sides of the support plate 503, and the opposite ends of the two support shafts 505 are respectively connected to the support plate 503 through the connecting seats 502. The other end of one of the support shafts 505 is connected to a motor 506, and the motor 506 is fixed outside the bearing seat 501. Since the processing surface of the sheet metal part has a recess, the metal chips in the processing process will be temporarily stored in the recess and are not easy to clean. In the limiting mechanism 5, the motor 506 can drive the support plate 503 to rotate through the support shaft 505, thereby providing a flipping of the sheet metal part. The metal chips remaining on the surface of the sheet metal part will fall into the waste collection tank 4 under the action of gravity and the vibration of the vibrator 504 for temporary storage, thereby ensuring the thoroughness of metal chip cleaning.

[0035] Reference Figure 4 In a preferred embodiment, the stabilizing mechanism 7 includes a cylinder 706, a U-shaped bracket 703 connected to the cylinder 706, and an extension plate 701 fixed to one side of the support plate 503.

[0036] Reference Figure 4 In a preferred embodiment, one end of the extension plate 2 701 is provided with an angled corner 702, and the U-shaped bracket 703 is snapped onto the outside of the extension plate 2 701, with the inner wall of the U-shaped bracket 703 fitting against the outer wall of the extension plate 2 701.

[0037] Reference Figure 4 In a preferred embodiment, the cylinder 706 includes an output rod 705, which is connected to a U-shaped insert 703. A support frame 707 is fixedly connected to the outside of the cylinder 706, and a plurality of limiting inserts 704 are movably inserted inside the support frame 707.

[0038] Reference Figure 4In a preferred embodiment, multiple limiting rods 704 are simultaneously connected to one side of the U-shaped bracket 703. A second support plate 708 is fixedly connected to the bottom end of the support frame 707, and multiple support seats 709 are fixedly connected to the top end of the second support plate 708. The top end of each support seat 709 is attached to the outer wall of the limiting rod 704. When the first support plate 703 is in a horizontal state, the output rod 705 is extended by the cylinder 706, causing the U-shaped bracket 703 to move closer to the second extension plate 701. During the approach process, the output rod 705 is extended by the second extension plate 701. The bevel 702 at the end can correct the support plate 503 during the U-shaped bracket 703 snap-fit ​​process, ensuring that it is in a completely horizontal state. The inner wall of the U-shaped bracket 703 limits the extension plate 701, which can enhance the stability of the support plate 503 and prevent the sheet metal parts from shaking during the milling process. In addition, the movement of the U-shaped bracket 703 can be limited by the limiting rod 704, and the support base 709 can provide stable support for the limiting rod 704, further optimizing the stability of the movement of the U-shaped bracket 703.

[0039] Working principle: In the anti-splash mechanism 2, the linear guide rail 201 drives the slider 202 to move up and down. Before the milling operation, it drives the trapezoidal outer cover 205 to move down, and the electromagnetic plate 207 is energized, so that the electromagnetic plate 207 fits against the lower metal frame 206 to fix the position of the trapezoidal outer cover 205. At the same time, based on the setting of the elastic sealing sleeve 208, a shield is established between the trapezoidal outer cover 205 and the tool holder 1, thereby blocking the splash path of metal chips that splash from multiple directions during the milling process, allowing the metal chips to fall down smoothly for collection. This avoids damage to the equipment surface during the metal chip splashing process and does not obstruct the milling process. At the same time, since the processing surface of the sheet metal part has a recess, and the metal chips during the processing will be temporarily stored in the recess and are not easy to clean, in the limiting mechanism 5, the motor 506 drives the support plate 503 to rotate through the support shaft 505, thereby providing a flipping for the sheet metal part, and the surface of the sheet metal part... The remaining metal shavings will fall into the waste collection tank 4 under the influence of gravity and the vibration of the vibrator 504, thus ensuring the thoroughness of metal shaving removal. In addition, when the support plate 503 is in a horizontal state, the output rod 705 is extended by the cylinder 706, which drives the U-shaped bracket 703 to move closer to the extension plate 701. During the approach, the bevel 702 set at one end of the extension plate 701 can correct the support plate 503 during the U-shaped bracket 703 engagement, ensuring that it is in a completely horizontal state. The inner wall of the U-shaped bracket 703 limits the extension plate 701, which can enhance the stability of the support plate 503 and prevent the sheet metal parts from shaking during the milling process. In addition, the movement of the U-shaped bracket 703 can be limited by the limiting rod 704, and the support base 709 can provide stable support for the limiting rod 704, further optimizing the stability of the movement of the U-shaped bracket 703.

[0040] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
