Description

Technical Field

[0001] The invention relates to the technical field of machining centers, and more specifically, to a five-axis five-linkage milling and turning composite machining equipment. Background Art

[0002] The five axes in the five-axis five-linkage milling machine refer to the three linear coordinate axes of X, Y, and Z and any two rotary coordinate axes. The five-axis linkage CNC machine tool is a high-tech processing equipment, mainly used for processing complex spatial surfaces. It controls the simultaneous movement of three linear coordinate axes (X, Y, and Z) and two rotary coordinate axes to achieve continuous trajectory control, thereby processing parts with complex surfaces, such as blades, propellers, and wings. The movement of these coordinate axes can be achieved by the movement of the workbench or the tool, but the direction is defined by the movement direction of the tool relative to the workpiece. The realization of five-axis linkage enables the processing tool to be positioned and connected in five degrees of freedom when processing parts with relatively complex geometric shapes, thereby improving the processing accuracy and efficiency.

[0003] When the milling and turning composite processing equipment processes the workpiece, a large amount of chips will be generated. The chips will cause friction between the workpiece and the tool, and the friction will generate static electricity. When the chips enter the equipment, they will fall on the brake pads and be adsorbed due to the static electricity. If the brakes are applied at this time, the chips will slide on the surface of the brake pads, forming numerous grooves, which will reduce the effective contact area of ​​the brake pads and affect the braking performance.

[0004] In the prior art, in order to avoid the above situation, a method is adopted to blow gas to the contact surface between the tool and the workpiece during cutting to blow off the chips. However, during five-axis linkage machining, the contact surface between the tool and the workpiece will constantly change, and during the prior art chip removal, the direction of gas blowing is fixed and cannot adapt to the changes in the location where the chips are generated. Some chips will be blocked by the contact area between the tool and the workpiece, and it is difficult to withstand the cleaning effect of gas blowing, resulting in incomplete chip removal. Summary of the invention

[0005] The present invention provides a five-axis five-linkage milling and turning composite processing equipment, which solves the technical problem in the related art that the chip removal during gas blowing will be blocked by the contact part between the tool and the workpiece.

[0006] The present invention provides a five-axis five-link milling and turning composite processing equipment, comprising a housing, a milling and turning composite machine body and a blowing component, wherein the housing is loaded with a matching milling and turning composite machine body and a blowing component;

[0007] The blowing component includes a support rod, an action mechanism, a transmission mechanism, a mounting head and an air jet head. The action mechanism is installed on the support rod, driving the air jet head to move while ejecting air. The action trajectory is a circular ring. The air jet head ejects air toward the center point of the circular ring trajectory. The contact part between the tool head and the workpiece is at the center point of the circular ring trajectory.

[0008] The two nozzles are symmetrically mounted on the mounting head. A transmission mechanism is provided between the mounting head and the actuating mechanism. When the actuating mechanism drives the nozzles to move, the mounting head is radially rotated through the transmission mechanism, and the two nozzles rotate around the center of the mounting head.

[0009] As a further solution of the present invention: the action mechanism includes a lower plate body, an upper plate body, a carrier plate, a roller, a motor, a gear part and a vertical shaft, the lower plate body and the upper plate body are both in annular shape, the lower plate body is fixedly installed on the top of the support rod, the upper plate body is fixed on the lower plate body, the outer edge of the lower plate body is in the shape of a rack, a carrier plate is mounted on the upper plate body, a roller is rotatably installed on the carrier plate, the roller cooperates with the edge of the upper plate body, a motor is fixedly installed on the carrier plate, a vertical shaft is rotatably installed on the carrier plate, the output end of the motor is fixed to the vertical shaft, and a gear part meshing with the edge of the lower plate body is fixed on the end of the vertical shaft.

[0010] As a further solution of the present invention: the inner diameters of the upper plate body and the lower plate body are consistent, and the outer diameter of the upper plate body is larger than that of the lower plate body.

[0011] As a further solution of the present invention: there are four rollers distributed at the four corners of the bottom of the carrier plate, and the rollers are in extrusion contact with the edge of the upper plate body.

[0012] As a further solution of the present invention: the transmission mechanism includes a bevel gear 1, a loading frame, a horizontal shaft and a bevel gear 2, the bevel gear 1 is fixedly sleeved on the vertical shaft, the loading frame is fixedly installed on the top surface of the carrier plate, the horizontal shaft is rotatably installed in the loading frame, one end of the horizontal shaft is fixedly connected to the mounting head, and the other end is fixedly installed with a bevel gear 2, the bevel gear 2 is meshed with the bevel gear 1, and there are two jet heads, which are symmetrically fixedly installed on the mounting head.

[0013] As a further solution of the present invention: the blowing component also includes a control mechanism, and the control mechanism includes a camera and a PLC controller loaded on a carrier plate, and the camera, the PLC controller and the motor are electrically connected.

[0014] As a further solution of the present invention: the milling-turning compound machine body includes a machine base, guide rail one, a machine head, a cutter head, guide rail two, guide rail three, a workpiece carrier and a swing head, wherein guide rail one is installed on one side of the machine base, and guide rail two is installed on the other side, the machine head is slidably arranged on the guide rail one, the cutter head and the swing head are installed on the machine head, the cutter head is rotated along the axis B through the machine head, and the cutter head is swung along the axis C through the swing head, guide rail three is slidably arranged on the guide rail two, and the workpiece carrier is slidably arranged on the guide rail three.

[0015] As a further solution of the present invention, the machine head slides along the Z-axis relative to the guide rail, thereby controlling the vertical distance between the tool head and the workpiece placed on the workpiece carrier.

[0016] As a further solution of the present invention, the guide rail three slides relative to the guide rail two along the X-axis direction, thereby controlling the workpiece placed on the workpiece carrier to move and feed horizontally upward and left and right.

[0017] As a further solution of the present invention, the workpiece carrier slides along the Y-axis relative to the guide rail three, thereby controlling the horizontal upward forward and backward movement of the workpiece placed on the workpiece carrier.

[0018] The beneficial effects of the present invention are:

[0019] The airflow generated by the jet head in the present invention is blown to the contact part between the tool head and the workpiece, so as to remove the chips generated during turning and milling and prevent them from accumulating. The processing characteristic of five-axis linkage is that the contact part between the tool and the workpiece will have an angle change. Therefore, the simple airflow action cannot effectively remove the chips on the side blocked by the tool and the workpiece. Therefore, the present invention provides a circular action trajectory for the jet head through the action mechanism to cover all angles of contact between the tool and the workpiece during processing, thereby ensuring that the chips are completely removed.

[0020] When the transmission mechanism is in use, the rotation of the vertical shaft causes the horizontal shaft to rotate through the meshing of bevel gear 1 and bevel gear 2, thereby causing the mounting head to rotate, so that the two jet heads on the mounting head rotate synchronously. In this way, the jet action can be adjusted in the above-mentioned motion trajectory and can also rotate in the axial direction of the horizontal shaft. Under the premise of not changing the size of the jet head, this setting can significantly increase the output range of the jet action, so that the coverage of the jet action is further improved.

[0021] The circular trajectory formed by the action mechanism is divided into several nodes, and the jet cleaning effect is performed at a certain node. The camera takes pictures synchronously, and the PLC controller receives the image information from the camera and analyzes and processes the image information. When it detects that there are chips remaining between the corresponding tool head and the workpiece, the motor is kept not started, and the jet head continues to blow at the current angle until the chip residue is completely removed. The PLC controller then drives the motor to rotate, so that the jet head enters the next node and stops. The jet cleaning repeats the above-mentioned detection mechanism at the same time, so that the trajectory movement effect given to the jet head by the action mechanism is no longer just a mechanical repetitive operation, but has an intelligent judgment to adjust the blowing duration according to the chip accumulation situation.

[0031] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0032] At least one embodiment of the present invention discloses a five-axis five-link milling and turning composite machining equipment, such as Figure 1 - Figure 8 As shown, it comprises a shell 1, a milling-turning composite body 2 and a blowing component 3, wherein the shell 1 is loaded with the matching milling-turning composite body 2 and the blowing component 3;

[0033] The milling and turning compound machine body 2 comprises a machine base 21, a guide rail 1 22, a machine head 23, a cutter head 24, a guide rail 25, a guide rail 3 26, a workpiece carrier 27 and a swing head 28, wherein a guide rail 1 22 is installed on one side of the machine base 21, and a guide rail 25 is installed on the other side, a machine head 23 is slidably arranged on the guide rail 1 22, a cutter head 24 and a swing head 28 are installed on the machine head 23, the cutter head 24 is rotated along the B axis by the machine head 23, and the cutter head 24 is swung along the C axis by the swing head 28, a guide rail 3 26 is slidably arranged on the guide rail 25, and a workpiece carrier 27 is slidably arranged on the guide rail 3 26;

[0034] When talking about the characteristics of five-axis machining, we have to compare it with traditional three-axis equipment. In daily production, three-axis machining equipment is more common, and there are several forms such as vertical, horizontal and gantry. Common processing methods include end mill end edge processing, side edge processing, ball end cutter profiling, etc., but no matter which form and method, there is a common feature, that is, the direction of the tool axis remains unchanged during the processing. The machine tool can only realize the movement of the tool in the spatial rectangular coordinate system through interpolation of the three linear axes of X, Y, and Z. Therefore, when faced with parts with complex surfaces, the disadvantages of low efficiency, poor surface quality and even inability to process of three-axis machine tools are exposed.

[0035] The five-axis linkage machining of the present invention specifically refers to:

[0036] The machine head 23 slides along the Z-axis relative to the guide rail 1 22, thereby controlling the vertical distance between the tool head 24 and the workpiece placed on the workpiece carrier 27;

[0037] The guide rail 3 26 slides relative to the guide rail 2 25 along the X-axis direction, thereby controlling the workpiece placed on the workpiece carrier 27 to move and feed horizontally upward and leftward;

[0038] The workpiece carrier 27 slides relative to the guide rail 3 26 along the Y-axis direction, thereby controlling the workpiece placed on the workpiece carrier 27 to move forward and backward in the horizontal direction;

[0039] The cutter head 24 rotates relative to the machine head 23 in the B axis direction, thereby controlling the posture of the cutter head 24 in the B axis direction;

[0040] The tool head 24 is swung along the C-axis relative to the machine head 23 by the swing head 28, so that the posture of the tool head 24 in the C-axis direction is controlled.

[0041] The processing actions in the above five directions are combined to form "five-axis linkage". It should be noted that each of the five axes has a driving component (not shown in the figure) for controlling its action. The specific driving structure has been maturely applied in the prior art for a long time and will not be described in detail here.

[0042] When the workpiece is loaded onto the workpiece carrier 27 for processing, the chips generated by the cutter head 24 acting on the workpiece will accumulate, and friction will be generated when the cutter head 24 contacts the workpiece and the cutter, and the friction will generate static electricity. In this way, when the chips enter the equipment, they will fall on the brake pad and be adsorbed due to the static electricity, affecting the braking performance. To solve this drawback, the present invention is specifically implemented as follows:

[0043] The blowing component 3 includes a support rod 31, an action mechanism 32, a transmission mechanism 33, a mounting head 34 and an air jet head 35. The action mechanism 32 is installed on the support rod 31, driving the air jet head 35 to move while ejecting air. The action trajectory is a circular ring. The air jet head 35 ejects air toward the center point of the circular ring trajectory. The contact part between the tool head 24 and the workpiece is at the center point of the circular ring trajectory.

[0044] The two nozzles 35 are symmetrically mounted on the mounting head 34. A transmission mechanism 33 is provided between the mounting head 34 and the actuating mechanism 32. When the actuating mechanism 32 drives the nozzles 35 to move, the mounting head 34 is radially rotated through the transmission mechanism 33, and the two nozzles 35 rotate around the center of the mounting head 34.

[0045] In the above implementation, first, the airflow generated by the air jet 35 is blown to the contact part between the tool head 24 and the workpiece, so that the chips generated during turning and milling can be removed and no longer accumulated. The processing characteristic of the five-axis linkage is that the contact part between the tool and the workpiece will change in angle. In this way, the simple airflow action cannot effectively remove the chips on the side blocked by the tool and the workpiece. For this reason, the present invention provides a circular action trajectory for the air jet 35 through the action mechanism 32 to cover all angles of contact between the tool and the workpiece during processing, thereby ensuring that the chips are completely removed. Specifically:

[0046] The action mechanism 32 includes a lower plate body 321, an upper plate body 322, a carrier plate 323, a roller 324, a motor 325, a gear part 326 and a vertical shaft 327. The lower plate body 321 and the upper plate body 322 are both annular. The lower plate body 321 is fixedly mounted on the top of the support rod 31, and the upper plate body 322 is fixed on the lower plate body 321. The outer edge of the lower plate body 321 is in a rack shape. A carrier plate 323 is mounted on the upper plate body 322, and a roller 324 is rotatably mounted on the carrier plate 323. The roller 324 cooperates with the edge of the upper plate body 322. The carrier plate 323 is fixedly mounted with a motor 325, and a vertical shaft 327 is rotatably mounted on the carrier plate 323. The output end of the motor 325 is fixed to the vertical shaft 327, and the end of the vertical shaft 327 is fixed with a gear part 326 that meshes with the edge of the lower plate body 321.

[0047] In this way, when the jet head 35 needs to be moved to eliminate the above-mentioned blocking influence, it is only necessary to drive the vertical shaft 327 to rotate through the motor 325, so that the gear part 326 rotates. The gear part 326 engages with the edge of the lower plate body 321, and the roller 324 cooperates with the edge of the upper plate body 322 to form a limiting effect, so that the carrier plate 323 can move in a circular trajectory around the upper plate body 322, and the jet head 35 moves synchronously. The chips on one side that were originally blocked by the tool and the workpiece can also be blown by the airflow generated by the jet head 35, and will no longer accumulate to produce friction, and will not be conducive to the braking performance in the later stage.

[0048] More specifically, the inner diameters of the upper plate 322 and the lower plate 321 are consistent, and the outer diameter of the upper plate 322 is larger than that of the lower plate 321. This arrangement allows a certain offset between the rotation of the roller 324 and the rotation of the gear 326 to avoid interference between the two.

[0049] In addition, there are four rollers 324 distributed at the four corners of the bottom of the carrier 323. The rollers 324 are in squeeze contact with the edge of the upper plate 322. This arrangement can stabilize the contact between the rollers 324 and the carrier 323, providing a stable limiting auxiliary effect when the carrier 323 moves.

[0050] The transmission mechanism 33 includes a bevel gear 1 331, a loading frame 332, a horizontal shaft 333 and a bevel gear 2 334. The bevel gear 1 331 is fixedly sleeved on the vertical shaft 327. The loading frame 332 is fixedly installed on the top surface of the carrier plate 323. The horizontal shaft 333 is rotatably installed in the loading frame 332. One end of the horizontal shaft 333 is fixedly connected to the mounting head 34, and the other end is fixedly installed with a bevel gear 2 334. The bevel gear 2 334 is meshed with the bevel gear 1 331. There are two jet heads 35, which are symmetrically fixedly installed on the mounting head 34.

[0051] When the transmission mechanism 33 is in use, the rotation of the vertical shaft 327 causes the horizontal shaft 333 to rotate through the meshing of the bevel gear 1 331 and the bevel gear 2 334, thereby causing the mounting head 34 to rotate, so that the two jet heads 35 on the mounting head 34 rotate synchronously. In this way, the jet action can be adjusted in the axial direction of the horizontal shaft 333 while the motion trajectory can be adjusted as mentioned above. Under the premise of not changing the size of the jet head 35, this arrangement can significantly increase the output range of the jet action, so that the coverage of the jet action is further improved.

[0052] For the trajectory movement of the jet head 35 under the action of the action mechanism 32, an automatic control mechanism can also be introduced to improve the automation and intelligence of its action, specifically:

[0053] The blowing component 3 further includes a control mechanism 36 , which includes a camera 361 and a PLC controller 362 mounted on a carrier plate 323 . The camera 361 , the PLC controller 362 and the motor 325 are electrically connected.

[0054] The circular trajectory formed by the action mechanism 32 is divided into several nodes, and the jet cleaning action is performed at a certain node. The camera 361 takes pictures synchronously, and the PLC controller 362 receives the image information from the camera 361 and analyzes and processes the image information. However, when it is detected that there are still chips remaining between the corresponding tool head 24 and the workpiece, the motor 325 is kept not started, and the jet head 35 continues to blow at the current angle until the chip residue is completely removed. The PLC controller 362 then drives the motor 325 to rotate, so that the jet head 35 enters the next node and stops. The jet cleaning repeats the above-mentioned detection mechanism at the same time, so that the trajectory movement effect assigned to the jet head 35 by the action mechanism 32 is no longer just a mechanical repetitive operation, but has an intelligent judgment to adjust the blowing duration according to the chip accumulation situation.

[0055] The above describes an embodiment of the present invention, but this embodiment is not limited to the above-mentioned specific implementation mode. The above-mentioned specific implementation mode is merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make more forms of equivalent embodiments, all of which are within the protection of this embodiment.
