Description

Technical Field

[0001] This invention relates to the field of machining center technology, and more specifically to a profile machining center with a follow-up tool magazine and a quick tool change structure. Background Technology

[0002] Currently, machining centers with automatic tool changers typically have the following configuration: the tool magazine is fixed to the machine tool support, while a moving platform equipped with the spindle (machining head) performs the cutting motion in the machining area. When a tool change is required, the spindle must move from its initial position on the workpiece to the fixed position of the tool magazine to perform the tool change operation. After the tool change is complete, it returns to its original initial position. This tool change process results in an additional reciprocating travel of the spindle between the machining area and the tool magazine. This travel consumes valuable machining time, increases the non-cutting operation time of the equipment, and reduces overall machining efficiency. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a profile machining center with a follow-up tool magazine and a fast tool changing structure to solve the problems in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A profile machining center with a follow-up tool magazine and a quick tool change structure, the profile machining center comprising:

[0006] Base

[0007] The first motion mechanism is mounted on the base;

[0008] A second motion mechanism is mounted on the first motion mechanism and moves along the X-axis and Y-axis directions on the base following the first motion mechanism; wherein, the second motion mechanism includes a Z-axis motion unit and a main shaft, and the main shaft is mounted on the Z-axis motion unit;

[0009] The tool magazine is connected to the first motion mechanism via a follower mechanism. The tool magazine is provided with several tool changing chucks for the spindle to pick up and put down tools. The Z-axis motion unit drives the spindle to move up and down along the Z-axis, and drives the follower mechanism to move the tool magazine between an initial position and a tool changing position, so that the spindle and the tool changing chucks of the tool magazine move closer to each other to perform tool picking and putting actions or move further apart to perform machining actions.

[0010] In one embodiment, the base has a first worktable and a second worktable, the top surface of the first worktable being higher than the top surface of the second worktable, the second worktable being disposed in front of the first worktable, and the first and second worktables being connected to form a stepped shape, the top surface of the second worktable being used to place the workpiece to be processed, the first motion mechanism being disposed on the top surface of the first worktable, and the spindle being located above the surface of the second worktable; wherein, the second worktable is used to install tooling fixtures, and the tooling fixtures are used to clamp the workpiece to be processed.

[0011] In one embodiment, a material collection mechanism is also included. A placement position is provided at the bottom of the second workbench. The second workbench is also provided with a plurality of discharge channels. The plurality of discharge channels connect from the top surface of the second workbench to the placement position at the bottom of the second workbench. The material collection mechanism is disposed at the placement position to collect the waste chips and waste liquid discharged from the discharge channels.

[0012] In one embodiment, the first worktable of the base is covered with two accordion covers, and the first motion mechanism is located between the two accordion covers.

[0013] In one embodiment, the follower mechanism includes:

[0014] The mounting bracket is installed on the first motion mechanism, and the tool magazine is rotatably connected to the mounting bracket;

[0015] A tension spring, with its two ends rotatably connected to the mounting bracket and the tool magazine, respectively;

[0016] When the spindle rises, the tool magazine rotates around the mounting bracket to the initial position under the drive of the spindle, and the tension spring follows the rotation of the tool magazine from the initial state to the extended state;

[0017] When the spindle descends, the tension spring returns from the extended state to the initial state under elastic action, and drives the tool magazine to rotate around the mounting bracket from the initial position to the tool changing position.

[0018] In one embodiment, the follower mechanism further includes:

[0019] A guide plate is mounted on the second motion mechanism and can move up and down following the main shaft; wherein the guide plate has a guiding portion;

[0020] A guide member is installed on the tool magazine. Under the action of the tension spring, the guide member always abuts against the surface of the guide portion so that when the guide plate moves up and down with the spindle, the tool magazine switches between the initial position and the tool changing position.

[0021] In one embodiment, the mounting bracket includes a fixed bracket and a rotating component. The fixed bracket is mounted on the first motion mechanism, and the rotating component is mounted on the fixed bracket. The rotating component is rotatably connected to the tool holder.

[0022] The tool magazine is equipped with a tool holder, and the tool magazine is rotatably connected to the rotating component through the tool holder.

[0023] In one embodiment, the guide is a rotary bearing, which is mounted on the tool holder and rotates relative to the tool holder under the drive of the guide.

[0024] In one embodiment, one end of the tension spring is rotatably connected to the tool holder, and the other end is rotatably connected to the fixed frame.

[0025] In one embodiment, the tool magazine is provided with a drive unit and a tool turntable, and the tool turntable is provided with a plurality of clamping mechanisms arranged in a circumferential array, each of the clamping mechanisms being provided with a tool changing chuck.

[0026] Compared with existing technologies, the beneficial effects of this invention are as follows:

[0027] The tool magazine is connected to the first motion mechanism via a follower mechanism, thereby achieving synchronous movement with the second motion mechanism. The follower mechanism drives the tool magazine between its initial position and tool-changing position, allowing the spindle and the tool magazine's tool-changing jaws to either move closer together for tool changing or move further apart for machining. Since the first motion mechanism drives the second motion mechanism to the machining position, it synchronously drives the tool magazine to follow the spindle. When the spindle needs to change tools, it does not need to move from the current workpiece's initial position to the fixed position of the tool magazine for tool changing and then return to its original initial position. By controlling the spindle's lifting and lowering, the follower mechanism can drive the tool magazine and spindle to move closer together for tool changing or move further apart to avoid interfering with machining. This greatly avoids the spindle generating additional large strokes and complex reciprocating strokes between the machining area and the tool magazine, reducing the consumption of effective machining time and the equipment's non-cutting running time, and improving overall machining efficiency.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figures 1 to 9 As shown, the present invention provides a profile machining center with a follow-up tool magazine and a quick tool change structure. The profile machining center includes:

[0040] Base 1,

[0041] The first motion mechanism 2 is mounted on the base 1;

[0042] The second motion mechanism 3 is mounted on the first motion mechanism 2 and moves along the X-axis and Y-axis directions on the base 1 following the first motion mechanism 2; wherein, the second motion mechanism 3 includes a Z-axis motion unit 31 and a main spindle 32, and the main spindle 32 is mounted on the Z-axis motion unit 31;

[0043] Tool magazine 4 is connected to the first motion mechanism 2 via follower mechanism 5. Tool magazine 4 is provided with several tool changing chucks 421 for the spindle 32 to pick up and put down tools. The Z-axis motion unit 31 is used to drive the spindle 32 to move up and down along the Z-axis, and drive the follower mechanism 5 to drive the tool magazine 4 to move between the initial position and the tool changing position, so that the spindle 32 and the tool changing chucks 421 of the tool magazine 4 move closer to each other to perform tool picking and putting actions or move further apart to perform machining actions.

[0044] In this embodiment, the tool magazine 4 is connected to the first motion mechanism 2 via a follower mechanism 5, thereby achieving synchronous movement with the second motion mechanism 3. The follower mechanism 5 drives the tool magazine 4 to move between the initial position and the tool changing position, switching the profile machining center to the machining state or the tool changing state. This allows the spindle 32 and the tool changing chuck 421 of the tool magazine 4 to move closer to each other to perform tool changing actions, or to move further apart to perform machining actions. Since the first motion mechanism 2 drives the second motion mechanism 3 to move to the machining position, it can synchronously drive the tool magazine 4 to move with the spindle 32. When the spindle 32 needs to change tools, it does not need to move from the current workpiece initial position to the fixed position of the tool magazine 4 to perform the tool changing operation. After the tool changing is completed, it returns to the original initial position. By controlling the spindle 32 to rise and fall, the follower mechanism 5 can drive the tool magazine 4 to move closer to the spindle 32 to change tools, or to move further apart to avoid interfering with the machining work. This greatly avoids the spindle 32 generating additional large strokes and complicated reciprocating strokes between the machining area and the tool magazine 4, reducing the consumption of effective machining time and the non-cutting running time of the equipment, and improving the overall machining efficiency.

[0045] The first motion mechanism 2 includes an X-axis motion unit 21 and a Y-axis motion unit 22. The X-axis motion unit 21 and the Y-axis motion unit 22 drive the second motion mechanism 3 to move on the base 1, so as to move along the X-axis direction and the Y-axis direction.

[0046] It should be noted that the X-axis motion unit 21, Y-axis motion unit 22, and Z-axis motion unit 31 are existing three-axis motion mechanisms, which achieve the movement of the spindle 32 and tool magazine 4 through the cooperation of motors, lead screws, etc., or through the cooperation of motors, gears, and racks. No limitation is made here. A slider and slide rail can also be used to improve operational stability.

[0047] Among them, such as Figure 1 , Figures 3 to 7 As shown, the X-axis motion unit 21 is mounted on the base 1, the Y-axis motion unit 22 is mounted on the X-axis motion unit 21, and the second motion mechanism 3 is mounted on the Y-axis motion unit 22. The X-axis motion unit 21 moves along the X-axis direction on the base 1, which drives the Y-axis motion unit 22, the second motion mechanism 3, and the tool magazine 4 to move along the X-axis direction. The Y-axis motion unit 22 moves along the Y-axis direction on the X-axis motion unit 21, which drives the second motion mechanism 3 and the tool magazine 4 to move along the Y-axis direction. The Z-axis motion unit 31 drives the spindle 32 to move up and down along the Z-axis direction on the Y-axis motion unit 22, thereby realizing the conversion of the machining center between the machining state and the tool changing state.

[0048] It should be noted that the X-axis motion unit 21 includes an X-guide rail, an X-slide, and an X-drive component. The X-guide rail is mounted on the first worktable 11, and the X-slide is slidably connected to the first worktable 11. An X-drive nut is provided at the bottom of the X-slide. The X-drive component is mounted on the first worktable 11, and a screw is driven to the drive end of the X-drive component. The screw is engaged with the X-drive nut for transmission. The X-drive component drives the screw to rotate forward and in reverse, thereby driving the X-slide to reciprocate on the first worktable 11. The X-drive component is a motor. A Y-guide block is provided on the X-slide, and the Y-axis motion unit 22 is mounted on the Y-guide block of the X-slide.

[0049] The Y-axis motion unit 22 includes a Y-guide rail, a Y-slide, and a Y-drive component. The Y-guide rail is mounted on the Y-slide, and the Y-slide is slidably connected to the Y-guide block via the Y-guide rail. A Y-drive nut is provided at the bottom of the Y-slide. The Y-drive component is mounted on the X-slide, and a screw is driven to the drive end of the Y-drive component. The screw is engaged with the Y-drive nut for transmission. The Y-drive component drives the screw to rotate forward and in reverse, thereby driving the Y-slide to reciprocate on the X-slide. The Y-drive component is a motor. A Z-guide block and a Z-drive nut are provided on the Y-slide. The Z-axis motion unit 31 is mounted on the Z-guide block of the Y-slide.

[0050] The Z-axis moving parts include a Z-guide rail, a Z-sliding frame, and a Z-drive component. The Z-guide rail is mounted on the Z-sliding frame, which is slidably connected to the Z-guide block via the Z-guide rail. The Z-drive component is mounted on the Z-sliding frame, and a screw is connected to the drive end of the Z-drive component. The screw is engaged with the Z-drive nut for transmission. The Z-drive component drives the screw to rotate forward and in reverse, thereby driving the Z-sliding frame to reciprocate up and down on the Y-slide. The Z-drive component is a motor, and the main shaft 32 is mounted on the Z-sliding frame.

[0051] like Figure 2As shown, in one embodiment, the base 1 has a first worktable 11 and a second worktable 12. The top surface of the first worktable 11 is higher than the top surface of the second worktable 12. The second worktable 12 is disposed in front of the first worktable 11, and the first worktable 11 and the second worktable 12 are connected to form a stepped shape. The top surface of the second worktable 12 is used to place the workpiece to be processed. The first motion mechanism 2 is disposed on the top surface of the first worktable 11, and the spindle 32 is located above the surface of the second worktable 12. The second worktable 12 is used to install tooling fixtures, and the tooling fixtures are used to clamp the workpiece to be processed.

[0052] In this embodiment, the base 1 has a first workbench 11 and a second workbench 12, and the first workbench 11 and the second workbench 12 form a stepped shape. When the first motion mechanism 2 processes the workpiece placed on the second workbench 12 on the first workbench 11, since the first workbench 11 is higher than the second workbench 12, it can effectively prevent iron filings from flying out of the machining center in the direction of the first workbench 11 or splashing onto the first workbench 11 and affecting the movement of the first motion mechanism 2, avoiding accidents, improving production safety, and facilitating the unified collection of iron filings generated during processing.

[0053] like Figure 1 As shown, in one embodiment, a material collection mechanism 6 is also included. A placement position is provided at the bottom of the second workbench 12. The second workbench 12 is also provided with a plurality of discharge channels 121. The plurality of discharge channels 121 connect from the top surface of the second workbench 12 to the placement position at the bottom of the second workbench 12. The material collection mechanism 6 is provided at the placement position to collect the waste chips and waste liquid discharged from the discharge channels 121.

[0054] In this embodiment, by setting a discharge channel 121 on the second workbench 12 and placing the discharge channel 121 below the positioning plate, the waste generated during processing can be collected.

[0055] In this design, a baffle is installed in front of the second worktable 12 of the base 1. During processing, the machining mechanism cuts the workpiece and generates iron filings. Under the high-speed rotation of the tool, the iron filings will splash in all directions. Since a baffle is installed in front of the second worktable 12, the iron filings are prevented from splashing out from the front of the second worktable 12. In this design, the first worktable 11 is connected to the second worktable 12 in a stepped manner. The first worktable 11 can block the iron filings, preventing them from flying out of the machine tool and falling onto the discharge channel 121 of the second worktable 12. The discharge channel 121 transports the iron filings out of the machining center and onto the collection mechanism 6 placed at the placement position. The coolant used to cool the tool also falls onto the collection mechanism 6 through the discharge channel 121 after cooling the tool, thus achieving unified collection of waste materials.

[0056] like Figure 1 As shown, in one embodiment, the first worktable 11 of the base 1 is covered with two accordion covers 13, and the first motion mechanism 2 is located between the two accordion covers 13.

[0057] In this embodiment, the first worktable 11 is protected from dust and dust by the bellows cover 13 to ensure operational stability. It also prevents iron filings from falling onto the first worktable 11 and affecting the operational stability of the first motion mechanism 2.

[0058] like Figure 3-7 As shown, in one embodiment, the follower mechanism 5 includes:

[0059] Mounting bracket 51 is mounted on the first motion mechanism 2, and tool magazine 4 is rotatably connected to mounting bracket 51;

[0060] The tension spring 52 is rotatably connected at both ends to the mounting bracket 51 and the tool magazine 4, respectively.

[0061] When the spindle 32 rises, the tool magazine 4 rotates around the mounting bracket 51 to the initial position under the drive of the spindle 32, and the tension spring 52 follows the rotation of the tool magazine 4 from the initial state to the extended state.

[0062] As the spindle 32 descends, the tension spring 52 returns from its extended state to its initial state under elastic action, and drives the tool magazine 4 to rotate around the mounting bracket 51 from its initial position to the tool changing position.

[0063] In this embodiment, the tool magazine 4 is able to rotate between the initial position and the tool change position as the spindle 32 rises and falls, thanks to the cooperation between the mounting bracket 51 and the tension spring 52.

[0064] like Figure 3-7 As shown, in one embodiment, the follower mechanism 5 further includes:

[0065] Guide plate 53 is mounted on the second motion mechanism 3 and can move up and down with the main shaft 32; wherein, guide plate 53 has guide part 531;

[0066] The guide 54 is installed on the tool magazine 4. Under the action of the tension spring 52, the guide 54 always abuts against the surface of the guide part 531 so that when the guide plate 53 moves up and down with the spindle 32, the tool magazine 4 switches between the initial position and the tool changing position.

[0067] In this embodiment, the guide plate 53 and guide member 54 are used together to ensure the working stability and coordinated rapid tool change effect of the spindle 32 and tool magazine 4.

[0068] like Figure 3-7 As shown, in one embodiment, the mounting bracket 51 includes a fixed bracket 511 and a rotating member 512. The fixed bracket 511 is mounted on the first motion mechanism 2, and the rotating member 512 is mounted on the fixed bracket 511. The rotating member 512 is rotatably connected to the tool holder 41.

[0069] The tool magazine 4 is equipped with a tool holder 41, and the tool magazine 4 is rotatably connected to the rotating component 512 through the tool holder 41.

[0070] In this embodiment, the tool magazine 4 is mounted on the first motion mechanism 2 by means of a fixed frame 511 and a rotating component 512 is mounted on the fixed frame 511. The rotating component 512 is rotatably connected to the tool holder 41 so that the tool magazine 4 is rotatably connected to the first motion mechanism 2 by means of a follower mechanism 5 following the rise or fall of the spindle 32, thereby achieving a rapid tool change effect.

[0071] like Figure 3-7 As shown, in one embodiment, the guide 54 is a rotary bearing, which is mounted on the tool holder 41 and rotates relative to the tool holder 41 under the drive of the guide part 531.

[0072] In this embodiment, by providing a rotatable rotating bearing, the sliding friction when it comes into contact with the guide portion 531 is transformed into rolling friction, which has less resistance and does not generate sharp noise.

[0073] like Figure 3-7 As shown, in one embodiment, one end of the tension spring 52 is rotatably connected to the tool holder 41, and the other end is rotatably connected to the fixing frame 511.

[0074] In this embodiment, the two ends of the tension spring 52 are rotatably connected to the tool holder 41 and the fixed frame 511 respectively, and cooperate with the spindle 32. Thus, through the elastic action, the position of the tool magazine 4 is switched, and it can cooperate with the spindle 32 to perform the tool changing operation.

[0075] like Figure 8-9As shown, in one embodiment, the tool magazine 4 is provided with a drive unit and a tool turntable 42. The tool turntable 42 is provided with a plurality of clamping mechanisms arranged in a circumferential array on its periphery, and each clamping mechanism is provided with a tool changing chuck 421.

[0076] In this embodiment, the tool turntable 42 is driven to rotate by a driving component, thereby enabling the rotation of multiple clamping mechanisms on the tool turntable 42 and achieving tool changing operation in coordination with the spindle 32.

[0077] The present invention arranges the tool magazine 4 and the second motion mechanism 3 on the first motion mechanism 2, so that the tool magazine 4 and the second motion mechanism 3 move synchronously with the first motion mechanism 2. When tool changing is required, the tool changing operation can be realized by raising or lowering the spindle 32 alone, without the first motion mechanism 2 driving the second motion mechanism 3 to move a large stroke, thus saving the time of the tool changing process.

[0078] like Figure 3-7 As shown, the tool changing operation process is as follows:

[0079] The guide section 531 of the guide plate 53 includes a first abutting section 5311, a second abutting section 5312, a third abutting section 5313, and a fourth abutting section 5314. The first abutting section 5311, the second abutting section 5312, the third abutting section 5313, and the fourth abutting section 5314 are arranged sequentially from bottom to top. The first abutting section 5311 and the fourth abutting section 5314 are both arranged in a straight line along the vertical direction. The first abutting section 5311 is arranged relatively close to the second motion mechanism 3. The fourth abutment section 5314 is positioned relatively away from the second motion mechanism 3. The second abutment section 5312 and the third abutment section 5313 are curved and extend sequentially from the first abutment section 5311 to the fourth abutment section 5314. The first abutment section 5311 and the fourth abutment section 5314 are connected by the second abutment section 5312 and the third abutment section 5313. The rotating bearing abuts against the guide plate 53. When the second motion mechanism 3 drives the spindle 32 to descend, it moves the guide plate 53 downward, causing the rotating bearing to move from the first abutment section 5311 of the guide plate 53 to the fourth abutment section 5314, thus changing the tool magazine 4 from the tool changing position to the initial position (e.g., ...). Figure 3-7 (As shown).

[0080] like Figure 3As shown, the tool magazine 4 has an initial position and a tool changing position due to the arrangement of the first abutment section 5311 and the fourth abutment section 5314 of the guide plate 53. When the rotating bearing abuts against the first abutment section 5311, the tool magazine 4 is in the tool changing position, and its lower end is close to the spindle 32 frame at this time, which is in the upper position. As the guide plate 53 moves down, the spindle 32 moves down to clamp the tool located on the tool changing chuck 421. At the same time, under the action of the follower mechanism 5, the rotating bearing moves from the first abutment section 5311 to the second abutment section 5312. When the rotating bearing moves to the second abutment section 5312, the spindle 32 moves down to complete the tool changing action. The rotating bearing continues to move along the second abutment section 5312 and the third abutment section 5313 until it abuts against the fourth abutment section 5314. At this time, the tool magazine 4 swings away from the second motion mechanism 3, providing space for the spindle 32 to move down.

[0081] like Figure 4 As shown, when the rotating bearing abuts against the fourth abutment section 5314, the tool magazine 4 is in its initial position, and its lower end is far from the spindle 32 frame at this time, and the spindle 32 frame is in a lower position. When changing tools, the spindle 32 drives the guide plate 53 to move upward. At the same time, under the action of the follower mechanism 5, the rotating bearing moves sequentially along the third abutment section 5313 and the second abutment section 5312 to the first abutment section 5311 on the fourth abutment section 5314. When the rotating bearing moves to the first abutment section 5311, the spindle 32 has completed its upward movement and is ready to perform the tool changing action. During this process, the tool magazine 4 swings towards the side closer to the second motion mechanism 3, and the tool changing chuck 421 approaches the spindle 32. During the upward movement, if there is a tool on the spindle 32, the tool is transferred from the spindle 32 to the tool changing chuck 421.

[0082] like Figure 3 As shown, the rotating bearing is tangent to the first abutment section 5311. In this state, the spindle 32 is concentric with the tool in the tool magazine 4 directly below the spindle 32. The rotating bearing is simultaneously tangent to the first abutment section 5311 and the second abutment section 5312. The tool magazine 4 reaches the tool changing position, the spindle 32 moves downward, and the bearing of the tool magazine 4 rolls along the second abutment section 5312 to complete the tool grabbing (the tool grabbing is achieved through the tool-catching cylinder).

[0083] like Figure 3-7 As shown, the rotating bearing is tangent to the first abutment section 5311. In this state, the spindle 32 and the tool in the tool magazine 4 directly below the spindle 32 are concentric. The bearing is simultaneously tangent to the first abutment section 5311 and the second abutment section 5312, and the tool magazine 4 reaches the tool changing position (as shown). Figure 3As shown), the spindle 32 moves downward, and the bearing of the tool magazine 4 rolls along the second abutment section 5312, completing the tool grabbing (achieved through the tool-grabbing cylinder). Simultaneously, the spindle 32 continues to move downward, the bearing rolls along the second abutment section 5312, and the tool magazine 4 swings to avoid the spindle 32. The spindle 32 continues to move downward, and the tool magazine 4 continues to open along the third abutment section 5313, finally reaching the fourth abutment section 5314 (as shown). Figure 4 As shown), the tool magazine 4 and the spindle 32 are in a reasonable state (without interference).
