Abstract
Description
Technical Field
[0001] The invention relates to the technical field of mechanical processing equipment, and in particular to an integrated processing machine tool. Background Art
[0002] During machine tool processing, as long as the workpiece is clamped, the clamped side of the workpiece cannot be processed. If the clamped side of the workpiece needs to be processed, the workpiece needs to be removed, then the direction is changed and re-clamped, and the initial position of the tool needs to be recalibrated. In addition, some workpieces are heavy, and when changing the clamping direction, it is time-consuming and laborious to move the workpiece, resulting in a slow processing cycle.
[0003] In a specific example, for example, the processing of automobile wheels requires turning or milling of both end faces, outer circles, inner hole walls, and screw holes and valve holes at the ends of the wheel hub. The wheel hub requires many processing steps, and even needs to be transported and switched between different machine tools to complete all processing steps. Similarly, when the wheel hub is processed, the clamped side cannot be processed, and both end faces of the wheel hub need to be processed. Switching between different processing steps may also require the use of a handling robot, which takes up a large space, takes a long time to switch between processes, and has a slow production cycle. Summary of the invention
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an integrated processing machine tool, which can complete more processing procedures than ordinary machine tools, and has fast switching of the workpiece clamping end, shortens the processing cycle, and improves production efficiency.
[0005] An integrated processing machine tool according to an embodiment of the present invention includes:
[0006] a bed having opposing first and second ends;
[0007] a first workpiece shaft device, the first workpiece shaft device being disposed at the first end and being used for clamping a workpiece;
[0008] a second workpiece shaft device, the second workpiece shaft device being arranged at the second end and also used for clamping the workpiece;
[0009] wherein the first workpiece axis device is coaxial with the second workpiece axis device, and the common axis is defined as a machining center axis;

This method is fast and efficient in switching the workpiece clamping side, shortening the processing cycle. In addition, since the first workpiece axis device and the second workpiece axis device are coaxial, after the workpiece switches the clamping side, the initial position of the tool can be calculated by the control program of the machine tool, and there is no need to readjust the initial position of the tool;

If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.
[0039] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0040] Reference Figure 1 As shown, an integrated processing machine tool according to an embodiment of the present invention comprises a bed 100, a first workpiece shaft device 200, a second workpiece shaft device 300, a guide transmission device 400, a first guide drive assembly 510, a rotation drive assembly 530 and a tool shaft assembly 520;
[0041] The bed 100 has a first end 110 and a second end 120 opposite to each other;
[0042] The first workpiece shaft device 200 is disposed at the first end 110 and is used to clamp the workpiece;
[0043] The second workpiece shaft device 300 is disposed at the second end 120 and is also used to clamp the workpiece;
[0044] The first workpiece axis device 200 is coaxial with the second workpiece axis device 300, and the common axis is defined as the machining center axis;
[0045] A guide transmission device 400 is further provided between the first workpiece shaft device 200 and the second workpiece shaft device 300, and the guide transmission device 400 can enable the first workpiece shaft device 200 and the second workpiece shaft device 300 to move relatively close to each other so as to transfer the clamped workpieces;
[0046] The first guide drive assembly 510 has a guide stroke perpendicular to the machining center axis and a guide stroke parallel to the machining center axis;
[0047] The rotation axis of the rotary drive assembly 530 is perpendicular to the machining center axis, and the rotary drive assembly 530 is connected to the first guide drive assembly 510;
[0048] One end of the tool shaft assembly 520 facing the machining center axis is used to install the tool. The tool shaft assembly 520 is set on the rotation drive assembly 530 to be driven to rotate around the rotation axis of the rotation drive assembly 530 to change the tool direction of the tool shaft assembly 520.
[0049] The first workpiece axis device 200 and the second workpiece axis device 300 can both adopt the spindle structure of a conventional machine tool, that is, the first workpiece axis device 200 can clamp the workpiece to be processed and rotate around the axis, and the second workpiece axis device 300 is the same. Preferably, the first workpiece axis device 200 and the second workpiece axis device 300 are both arranged horizontally, so that the machine tool control system can control the movement of the tool axis assembly 520 and calculate the processing feed amount.
[0050] The tool shaft assembly 520 can be configured as a turning tool or a milling cutter. When the tool on the tool shaft assembly 520 is configured as a turning tool, the first workpiece shaft device 200 clamps the workpiece and rotates around the axis, and the tool turns the workpiece; when the tool on the tool shaft assembly 520 is configured as a milling cutter, the first workpiece shaft device 200 only clamps the workpiece and remains stationary, and the milling cutter rotates to perform milling operations on the surface of the workpiece. To ensure that the tool shaft assembly 520 can switch between a turning tool and a milling cutter, it is only necessary to ensure that the tool shaft assembly 520 can drive the clamped tool to rotate around the axis of the tool. The tool shaft assembly 520 can be implemented by using a motor to drive the tool mounting part. When a tool for a milling cutter is used, the tool is driven to rotate; when a tool for a turning tool is used, the tool is locked in a stationary state.
[0051] The guide transmission device 400 can make the first workpiece axis device 200 and the second workpiece axis device 300 move relative to each other to approach each other, which can be achieved in a variety of ways. For example, the first workpiece axis device 200 remains stationary at the first end 110, and only the second workpiece axis device 300 moves toward the first workpiece axis device 200; or, the second workpiece axis device 300 remains stationary at the second end 120, and only the first workpiece axis device 200 moves toward the second workpiece axis device 300; or, both the first workpiece axis device 200 and the second workpiece axis device 300 can move and approach each other to transfer the clamped workpiece.
[0052] Both the first workpiece shaft device 200 and the second workpiece shaft device 300 can clamp the workpiece. Generally speaking, the workpiece is first clamped on the first workpiece shaft device 200, and the tool shaft assembly 520 drives the tool to process the workpiece. Then the workpiece is clamped on the second workpiece shaft device 300. Since the clamping position of the workpiece changes, the tool can now process one side of the first clamping part.
[0053] When the clamping direction of the workpiece needs to be changed, the guide transmission device 400 works to make the first workpiece axis device 200 and the second workpiece axis device 300 approach each other. At this time, the second workpiece axis device 300 can directly clamp the other end of the workpiece, and then the first workpiece axis device 200 releases the workpiece, that is, the workpiece handling switch is completed, and then the next processing step is continued. The use of this method to switch the clamping side of the workpiece is fast and efficient, shortening the processing cycle. In addition, since the first workpiece axis device 200 and the second workpiece axis device 300 are coaxial, after the workpiece switches the clamping side, the initial position of the tool can be calculated by the control program of the machine tool, and there is no need to re-adjust the initial position of the tool.
[0054] The rotary drive assembly 530 can change the tool orientation of the cutter shaft assembly 520. Specifically, when processing the circumferential surface of the workpiece, the tool orientation of the cutter shaft assembly 520 should be perpendicular to the machining center axis. Then, when the cutter shaft assembly 520 moves in a direction parallel to the machining center axis, the circumferential surface of the workpiece, such as the outer surface of the workpiece, can be processed. When the end face of the workpiece needs to be processed, the rotary drive assembly 530 adjusts the tool orientation of the cutter shaft assembly 520 to be parallel to the machining center axis. At this time, the position of the cutter shaft assembly 520 is further changed, so that the tool can be moved to the end face of the workpiece, and then it is processed. Generally, the processing of the end face of the workpiece is the hole processing of the end face, and the cutter shaft assembly 520 needs to be adjusted to milling processing. In this case, the cutter shaft assembly 520 is installed with a milling cutter, and the milling cutter orientation is parallel to the machining center axis, that is, the milling cutter is perpendicular to the end face of the workpiece, so that the end face of the workpiece can be milled. For a simple hole processing implementation scheme, the milling cutter can be replaced by a drill bit, because both the milling cutter and the drill bit belong to the solution of tool self-rotation.
[0055] Since the first guide drive assembly 510 has a guide stroke parallel to the machining center axis, the first guide drive assembly 510 can drive the knife shaft assembly 520 to move to the first workpiece shaft device 200 to process the workpiece clamped on the first workpiece shaft device 200. Then, the workpiece is transferred to the second workpiece shaft device 300, and the first guide drive assembly 510 can continue to drive the knife shaft assembly 520 to move to the second workpiece shaft device 300 to process the workpiece clamped on the second workpiece shaft device 300 to complete the full process of the workpiece. This method can realize the clamping side switching processing of the workpiece on a single machine tool, and there is no need to use an additional handling robot to transport and switch the clamping side of the workpiece.
[0056] It is understandable that the guide transmission device 400 includes a second guide drive assembly 410 , which is disposed on the bed 100 and has a guide stroke from the first end 110 to the second end 120 , and the second workpiece shaft device 300 is connected to the second guide drive assembly 410 .
[0057] This method is to control the movement of the second workpiece axis device 300 by the second guide drive assembly 410 to realize the movement of the second workpiece axis device 300 toward the first workpiece axis device 200 to complete the handling and switching of the workpiece. Furthermore, the second guide drive assembly 410 can be a combination of a screw rod and a guide rail for transmission. The screw rod is used because the feed amount of the screw rod can be more accurately regulated to meet the high-precision processing requirements. There are also many ways to set the guide rail, which mainly ensures that the guide rail is parallel to the machining center axis, so the guide rail can be set in the vertical plane of the bed 100, or in the horizontal plane of the bed 100.
[0058] Furthermore, the second guide drive assembly 410 includes a plurality of guide rails 411 and a transmission mechanism 412. The plurality of guide rails 411 are all arranged on the bed 100 and have a guide stroke from the first end 110 to the second end 120. At least one guide rail 411 is arranged on a vertical plane on one side of the bed 100. The second workpiece axis device 300 is slidably connected to the guide rail 411 so that the second workpiece axis device 300 is suspended on the outside of the bed 100. The transmission mechanism 412 is connected to the second workpiece axis device 300 to drive the second workpiece axis device 300 to move along the guide rail 411.
[0059] In conventional machine tools, the guide rails 411 are mostly all arranged on the horizontal plane of the bed 100, that is, after the second workpiece axis device 300 is connected to the guide rails 411, it is located directly above the bed 100. At this time, when the workpiece clamped by the second workpiece axis device 300 is processed, the debris falls on the bed 100, which is inconvenient to clean and collect. When at least one guide rail 411 is arranged on the vertical plane on one side of the bed 100, the second workpiece axis device 300 can be suspended outside one side of the bed 100. At this time, the debris generated by the workpiece processing will not fall on the bed 100, but on the outside of the bed 100. Further, a corresponding collection device is arranged below the second workpiece axis device 300 to collect the debris.
[0060] Reference Figure 2 As shown, it can be understood that the first guide drive assembly 510 includes a guide rail 511, a slide plate 512 and a column 513. The guide rail 511 is arranged on the bed 100 and is parallel to the machining center axis. The slide plate 512 is slidably connected to the guide rail 511 to move along the guide rail 511. The column 513 is vertically arranged and slidably connected to the slide plate 512, so that the column 513 can be horizontally close to the machining center axis, and the tool shaft assembly 520 is slidably connected to the column 513, so that the tool shaft assembly 520 can be vertically close to the machining center axis.
[0061] This scheme is a specific setting of the first guide drive assembly 510. The slide plate 512 can move along the guide rail 511, that is, move in the direction of the machining center axis, so that the tool shaft assembly 520 can move along the axial direction of the workpiece to complete the axial processing of the workpiece, including the outer surface and the inner surface. The column 513 can horizontally approach the machining center axis on the slide plate 512, and cooperate with the tool shaft assembly 520 to vertically approach the machining center axis on the column 513, so as to realize that the tool shaft assembly 520 approaches the workpiece perpendicular to the machining center axis, for example, to control the feed amount or retraction of the tool shaft assembly 520.
[0062] It can be understood that the rotary drive assembly 530 includes a rotary box 531 and a rotary shaft 532. The rotary box 531 is slidably connected to the column 513 and can move vertically on the column 513. The rotary shaft 532 is provided in the rotary box 531, and the rotary shaft 532 is perpendicular to the machining center axis. The tool shaft assembly 520 is connected to the rotary shaft 532, so that the rotary shaft 532 can drive the tool shaft assembly 520 to rotate around the axis of the rotary shaft 532 to adjust the direction of the tool. A tool magazine assembly 550 is also provided on the column 513. A plurality of different types of tools can be placed in the tool magazine assembly 550, so that the tool shaft assembly 520 can replace a plurality of tools at the tool magazine assembly 550.
[0063] Furthermore, the rotary shaft 532 can be driven by a driving mechanism disposed in the rotary housing 531 to rotate around its own axis, thereby realizing the rotation of the knife shaft assembly 520. Common driving mechanisms include a spindle motor and the like.
[0064] It can be understood that a first turret assembly 540 is provided on one side of the first workpiece axis device 200. The first turret assembly 540 is used to install a tool. The first turret assembly 540 has a moving stroke perpendicular to the machining center axis and a moving stroke parallel to the machining center axis.
[0065] The first turret assembly 540 and the tool shaft assembly 520 can be used together, wherein the first turret assembly 540 is dedicated to installing turning tools, and the tool shaft assembly 520 is dedicated to installing milling cutters or drill bits, reducing the steps of tool switching. The turret assembly is a common component on machine tools, generally composed of a tool changing mechanism and a tool holder disc for installing tools.
[0066] The first turret assembly 540 is mainly composed of a turret part and a guide part, the guide part is used to control the movement of the turret part in space, for example, using a multi-axial guide rail assembly to achieve displacement on the X axis, Y axis and Z axis, and the turret part is used to install various tools. The following second turret assembly 600 and third turret assembly 700 can also adopt this type of structural design.
[0067] It can be understood that a second turret assembly 600 is provided on one side of the first workpiece axis device 200. The second turret assembly 600 is used to install a tool. The second turret assembly 600 has a moving stroke perpendicular to the machining center axis and a moving stroke parallel to the machining center axis.
[0068] The second turret assembly 600 is used to install a tool, specifically a turning tool. The second turret assembly 600 can be preferably used to process the workpiece clamped by the first workpiece shaft device 200, and the turret assembly 520 can be moved to the second workpiece shaft device 300. It can be understood that after the first workpiece shaft device 200 completes the clamping process of the first workpiece, the workpiece is transferred to the second workpiece shaft device 300. At this time, the first workpiece shaft device 200 can synchronously receive a new workpiece, and the second turret assembly 600 processes the workpiece at the first workpiece shaft device 200, while the turret assembly 520 processes the workpiece at the second workpiece shaft device 300, making full use of time and improving processing efficiency.
[0069] It can be understood that a third turret assembly 700 is provided on one side of the second workpiece axis device 300. The third turret assembly 700 is used to install a tool. The third turret assembly 700 has a moving stroke perpendicular to the machining center axis and a moving stroke parallel to the machining center axis.
[0070] The third turret assembly 700 can be equipped with a turning tool, and is preferably used to process the workpiece clamped by the second workpiece shaft device 300, while the tool shaft assembly 520 is mainly used for milling.
[0071] It can be understood that a housing 610 is provided at the first end 110, and a chamber is provided in the housing 610, and the second turret assembly 600 is arranged in the chamber, and one end of the second turret assembly 600 extends out of the chamber and is located on one side of the first workpiece shaft device 200. The second turret assembly 600 is placed in the chamber of the housing 610, that is, the transmission mechanism and the like are also located in the chamber, so that when processing the workpiece, the generated debris directly falls below the first workpiece shaft device 200, which is helpful for chip removal.
[0072] It can be understood that a chip removal device 800 is provided, and the chip removal device 800 is located below the first workpiece shaft device 200 and the second workpiece shaft device 300 to receive and collect the chips generated during processing.
[0073] A specific embodiment includes that the chip removal device 800 includes a chip collecting groove 810 and a movable chip removal assembly 820, the chip collecting groove 810 is arranged below the first workpiece axis device 200 and the second workpiece axis device 300, and the upper end of the chip collecting groove 810 is open, and the movable chip removal assembly 820 is arranged in the chip collecting groove 810 and is placed along the length direction of the chip collecting groove 810 to discharge chips to one end of the chip collecting groove 810.
[0074] The chip trough 810 can simultaneously receive the chips generated when the workpieces clamped by the first workpiece shaft device 200 and the second workpiece shaft device 300 are processed. Compared with the multiple matching chip removal devices required when the workpiece is processed on multiple machine tools, only one set of mobile chip removal assembly 820 and chip trough 810 can reduce the energy consumption of the matching equipment. Timely removal of the chips generated by the workpiece processing can prevent the chips from accumulating on the bed 100, because the accumulated chips may enter the various guide drive components and affect the transmission accuracy of each component. The mobile chip removal assembly 820 can be specifically divided into a chip removal screw, a chip removal scraper, a flat chain, etc., which can transfer the chips to the end of the chip trough 810 by moving, so as to facilitate collection and processing.
[0075] Specifically, refer to Figure 3 and Figure 4As shown, taking the processing of a wheel hub 900 as an example, the parts of the wheel hub 900 that need to be processed include the left end face 910, the right end face 920, the outer cylindrical surface 930, the inner hole surface 940, the inner end face 950, the center hole 960, the screw hole 970 and the valve hole 980. The wheel hub 900 is first arranged to be clamped on the first workpiece shaft device 200. Specifically, the first workpiece shaft device 200 clamps the left end portion of the wheel hub 900 (where the left end face 910 is located), and the second turret assembly 600 processes the unclamped part of the outer cylindrical surface 930, and processes the inner hole surface 940, the inner end face 950 and the right end face 920. Of course, the processing of this part can also be assisted by the first turret assembly 540 and the turret assembly 520. After the workpiece is processed at the first workpiece shaft device 200, the second guide drive assembly 410 drives the second workpiece shaft device 300 to move to the first workpiece shaft device 200 to clamp the right end portion of the wheel hub 900, and then the first workpiece shaft device 200 is released, and the second workpiece shaft device 300 clamps the wheel hub 900 back to the second end 120.
