Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of profile machining manufacturing, in particular to a curtain wall profile machining center and a working method. BACKGROUND

[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute the prior art.

[0003] Compared with conventional door and window profiles, curtain wall profiles in construction projects have larger size and thickness to meet the wind pressure, seismic load and structural strength requirements of high-rise buildings.

[0004] For example, the cross-sectional size of a curtain wall profile is more than 100 mm, the wall thickness is commonly 2.5-12 mm, or even thicker; the cross-sectional size of a conventional door and window profile is between 50-80 mm, and the wall thickness is between 1.4-2.0 mm.

[0005] The curtain wall profile needs to be machined on the blank to form structures such as holes, grooves and special-shaped profiles to meet the connection and cooperation requirements with expansion bolts, fasteners and other components during installation, thus involving multiple machining processes such as drilling, milling, sawing and milling. When machining the profile in the traditional way, multiple machining equipment is needed. After the profile is fixed to the current machining equipment by a clamp to perform machining, the clamp needs to be removed and transported to the next machining equipment to perform another set of different machining process.

[0006] The volume, weight and structural complexity of the curtain wall profile far exceed those of conventional door and window profiles. If the traditional way is adopted for machining, multiple clamping and turning actions are involved, and multiple steps of clamping positioning and controlling the machining host are needed, which leads to low machining efficiency. At the same time, since the machining of the curtain wall profile cannot be completed at one time, larger cumulative errors are caused, resulting in unsatisfactory machining quality of the curtain wall profile.

[0024] The second aspect of the application provides a working method of the curtain wall profile machining center, comprising the following steps:

[0025] The profile is gripped by the mechanical gripper, sent into the drilling and milling machining unit along the X direction, and clamped and fixed by the fixed clamp and the follow-up clamp after reaching the set drilling and milling position, and the drilling and milling machining unit is fed from different cross section directions of the profile according to the machining requirement to perform drilling and milling machining;

[0026] After the drilling and milling machining is completed, the profile continues to move along the X direction in the state of being clamped and fixed by the fixed clamp and the follow-up clamp, and is fixed by the first sawing and milling clamp and the second sawing and milling clamp in the sawing and milling unit, and the first sawing and milling machining mechanism and / or the second sawing and milling machining mechanism are used to perform sawing and milling machining on the end of the profile according to the machining requirement.

[0027] After the sawing and milling machining is completed, the second sawing and milling clamp is loosened, the profile segment at the front is taken out by the discharge gripper and unloaded by the gripper at the discharge end, and the current machining cycle is ended.

[0028] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0029] 1. The drilling and milling machining and the sawing and milling machining required during the machining of the curtain wall profile are combined in one device, the curtain wall profile is sent into the machining center by the mechanical hand, the drilling and milling and the sawing and milling two-part machining are completed in sequence or synchronously through one clamping action, and after the machining is completed, the profile segment at the front is taken out by the discharge gripper to complete unloading, so that the error caused by frequent clamping in the traditional machining is reduced through one clamping process, and the machining precision and efficiency of the curtain wall profile are improved.

[0030] 2. The layout mode of the double gantry parallel arrangement can cover the full segment machining of the super-long profile (more than 6 meters), so that the profile can complete all processes through one clamping, and cumulative error caused by repeated positioning is avoided. During the machining, the load of the drilling and milling unit is mostly concentrated in the gantry A, the load of the first sawing and milling machining mechanism in the sawing and milling unit is concentrated in the base, and the load of the second sawing and milling machining mechanism is shared by the gantry A and the gantry B, so that the load distribution is more uniform, the drilling and milling unit and the sawing and milling unit can work in sequence or simultaneously, thereby the tact time is greatly shortened, and the production efficiency is improved.

[0031] 3. A follow-up fixture is installed to move with the machining mechanism. The profile to be machined moves along the X direction, passing through the follow-up fixture and the fixed fixture in sequence before being clamped and fixed for drilling and milling. During the preparation for the next drilling and milling stage after the first stage ends, the follow-up fixture maintains its clamping state and moves along the feed direction of the profile with the corresponding machining mechanism to the area required for the next stage of machining. During this movement, a set distance is maintained between the follow-up fixture and the followed machining mechanism to ensure that the position of each drilling and milling stage is sufficiently close to the clamping point formed by the follow-up fixture, thus solving the vibration problem caused by excessive clamping point distance during machining.

[0032] 4. Both the lateral and vertical sawing and milling machines have movement in the x, y, and z directions. Simultaneously, the lateral sawing and milling machine can swing around the y-axis, and the vertical sawing and milling machine can swing around both the y and z axes, thus forming a processing method with two sets of sawing and milling machines working in coordination (four-axis + five-axis). After the curtain wall profile is clamped, depending on the actual end structure, the lateral and vertical sawing and milling machines can be used individually, or in combination, to feed from both sides of the curtain wall profile, or from top to bottom, or from bottom to top. This can meet the processing requirements of most curtain wall profiles for their end structures, and is applicable to a wider range of profile end face types.

[0033] 5. During profile feeding, the profile passes sequentially through the first vertical clamping mechanism, the horizontal clamping mechanism, and the second vertical clamping mechanism. In the first vertical clamping mechanism, the support rollers and clamping rollers generate rolling friction with the profile surface rather than sliding friction, reducing the likelihood of scratches even if aluminum shavings are present. In the second vertical clamping mechanism, airflow from the vents in the two sets of fixed rollers blows onto the lower surface of the profile, forming an "air cushion." This "air cushion" reduces the pressure on the fixed rollers, thus reducing friction between the bottom surface of the profile and the fixed roller surface. Simultaneously, before passing the fixed rollers, the "air cushion" blows away aluminum shavings from the bottom surface of the profile, reducing the probability of shavings adhering to the bottom surface and thus solving the problem of surface scratches during profile processing.

DETAILED DESCRIPTION

[0058] The present application will be further described below in conjunction with the drawings and embodiments.

[0059] It should be noted that the following detailed description is exemplary in nature and is intended to provide further description of the application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0060] In this solution, "drilling and milling" includes the "drilling" process of machining a round hole (through hole or blind hole) on the profile with a drill bit, and the "milling" process of cutting the surface or edge of the profile with a rotating milling cutter to realize slotting, planing, contour forming, etc.

[0061] In this solution, "sawing and milling" includes "sawing" and "milling". "Sawing" refers to sawing off a part of the profile to completely separate the profile blank. "Milling" refers to sawing a narrow groove on the end of the profile, for example, the narrow groove is 8mm wide, and the saw blade is only 4mm thick, so two "milling" actions are required. At the same time, "sawing and milling" also includes machining the end face of the profile, such as removing burrs or protrusions on the end face.

[0062] In the drilling and milling process, the basic definition of "milling" (i.e. cutting work on the workpiece by rotating tool) is the same, and the core principle is to use a rotating tool (or saw blade) to remove material to achieve cutting, forming or surface machining, but there are differences in specific application scenarios, processing purposes and process emphases,

[0063] "Milling" in drilling and milling is mainly used for machining local features such as holes, grooves, steps, etc. (cooperating with drilling), such as hole expansion, keyway milling, chamfering, etc. It is usually a fine machining of existing holes or local areas, and emphasizes the cooperation with drilling.

[0064] "Milling" in sawing and milling is mainly used for correcting the sawing end face or machining the profile of the profile (cooperating with sawing, such as correcting the sawing end face, profile interface forming, process slotting, etc. It is usually a reprocessing of the overall profile or end face of the profile after sawing, and emphasizes the complementarity with sawing.

[0065] In this solution, the length direction of the profile is the x-axis or x-direction, the width direction is the y-axis or y-direction, and the height direction is the z-axis or z-direction, which are perpendicular to each other.

[0066] Unless specifically specified, "profile" appearing in the following examples refers to "curtain wall profile", i.e. aluminum alloy profile with cross-sectional width exceeding 100mm and wall thickness greater than 3mm, for example, a typical curtain wall profile specification is: width 385mm, height 200mm, wall thickness 3-12mm (can exceed 12mm).

[0067] Example 1:

[0068] The curtain wall profile machining center given in this embodiment is as follows Figures 1-3As shown, including the base 1, the upper surface of the base 1 is provided with gantry A2 and gantry B3 arranged side by side, the outer side of the gantry A2 is provided with a drilling and milling unit 4, and the space between the gantry A2 and the gantry B3 accommodates a sawing and milling unit 5.

[0069] The drilling and milling unit 4 includes a drilling and milling processing unit body, a fixed clamp and a follow-up clamp 41.

[0070] The sawing and milling unit 5 includes a first sawing and milling clamp 51 and a second sawing and milling clamp 52, and a first sawing and milling processing mechanism 53 and a second sawing and milling processing mechanism 54.

[0071] The profile is grabbed by a mechanical gripper and sent into the X direction Figure 1 The machining center shown, after the fixed clamp and the follow-up clamp 41 of the drilling and milling processing unit, is clamped and fixed, the drilling and milling processing unit body has six drilling and milling processing main machines, which respectively drill and mill from the upper, lower, left and right four directions of the profile section (each has two drilling and milling processing main machines), and each direction of the processing main machine has x, y, z three direction movement stroke, which can process holes or grooves that meet the process requirement distance, position and angle at one time;

[0072] After drilling and milling, the profile is sent into the subsequent sawing and milling unit 5 and fixed by the first sawing and milling clamp 51 and the second sawing and milling clamp 52, and the first sawing and milling processing mechanism 53 and the second sawing and milling processing mechanism 54, both of which can move in x, y, z three directions, among which the lateral sawing and milling main machine in the first sawing and milling processing mechanism 53 can also swing around the y axis, and the vertical sawing and milling main machine in the second sawing and milling processing mechanism 54 can also swing around the y and z axes, forming a four-axis + five-axis two-group sawing and milling main machine cooperation mode for sawing and milling;

[0073] After sawing and milling, the second sawing and milling clamp 52 is loosened, and the frontmost profile is taken out by the discharge gripper and unloaded. The whole process makes the curtain wall profile complete the required drilling and milling and sawing and milling through one clamping, can meet the processing needs of most curtain wall profiles for surface structure and end structure, meet the processing quality requirements, and the efficiency is higher than that of the traditional way.

[0074] The gantry itself has high rigidity and can resist vibration caused by cutting force to ensure processing accuracy. The layout mode of double gantries arranged side by side disperses the processing load and reduces the deformation caused by unilateral stress, which is especially suitable for heavy or long size profile processing. The length of a single curtain wall profile blank is about 7 meters, which is much longer than the length of conventional door and window profiles, and the wall thickness is also much larger than that of conventional door and window profiles, which meets the characteristics of heavy or long size profiles.

[0075] The parallel layout of the double gantry can cover the whole section processing of the super-long profile (more than 6 meters), so that all processes can be completed by clamping the profile once, avoiding cumulative errors caused by repeated positioning.

[0076] During the processing of the drilling and milling unit, most of the load is concentrated on the gantry A, in the sawing and milling unit, the load during the processing of the first sawing and milling processing mechanism 53 is concentrated on the base, the load during the processing of the second sawing and milling processing mechanism 54 is shared by the gantry A and the gantry B, and the load distribution is more uniform. It can support the simultaneous work of the drilling and milling part and the sawing and milling part, for example, drilling and milling unit processing hole system, sawing and milling unit synchronous processing notch structure, which can greatly shorten the tact time and improve the production efficiency (especially suitable for batch production).

[0077] The base 1 is designed as a structure with a cavity, and the aluminum chips generated during processing fall into the cavity of the base 1 by gravity, facilitating subsequent centralized recycling, for example, a conveyor belt or other mechanism can be arranged in the cavity of the base 1 to transport the generated aluminum chips out of the machining center.

[0078] As shown in Figure 4 The drilling and milling processing unit body includes a mounting plate 43 connected to the gantry A2, and the mounting plate 43 is provided with a feeding hole for accommodating the movement of the profile x, and the feeding hole is provided with a fixed clamp.

[0079] The mounting plate 43 is provided with a first horizontal processing mechanism 431, a first vertical processing mechanism 432, a second horizontal processing mechanism 433, and a second vertical processing mechanism 434, which are used for drilling and milling the profile from four side directions of the profile section. Each of the processing spindles has X, Y, and Z three-direction movements under the premise of being able to rotate, and each direction movement is driven by a motor driven ball screw mechanism, thereby ensuring that the processing precision meets the requirements.

[0080] As a further embodiment, the specific structure of the four groups of processing mechanisms is not limited, which can be a motor driven tool rotation forming processing host, and the processing host realizes X, Y, and Z three-direction movements through a support and a ball screw mechanism. Existing mature structures can be selected.

[0081] This embodiment takes the first vertical processing mechanism 432 as an example to explain the specific structure, including a processing host connected with a tool, the processing host is movably connected with an x-direction slide rail, the x-direction slide rail is connected to a first support, the first support is movably connected with a z-direction slide rail, the z-direction slide rail is connected to a second support, the second support is movably connected with a y-direction slide rail, and the y-direction slide rail is arranged on the mounting plate 43.

[0082] As a further embodiment, the first vertical machining mechanism 432 and the second vertical machining mechanism 434 are respectively located in the upper space and the lower space of the profile to be machined, and each has two machining main machines with different powers. The machining main machines with different powers are switched according to the needs of drilling and milling, for example, the profile with thick wall uses the machining main machine with larger power, which greatly improves the efficiency; the profile with thin wall uses the machining main machine with smaller power, which can save energy and avoid waste under the premise of meeting the efficiency; the upper and lower two sides are the common machining positions of curtain wall profiles, and the machining mechanisms each having two machining main machines also reduce the frequency of changing tools, which indirectly improves the machining efficiency.

[0083] As a further embodiment, the four sets of machining mechanisms have six machining main shafts in total, wherein the first vertical machining mechanism 432 and the second vertical machining mechanism 434 each have two machining main shafts, and the first horizontal machining mechanism 431 and the second horizontal machining mechanism 433 each have one machining main shaft, and the four sets of machining mechanisms form a six-machining-main-shaft arrangement mode.

[0084] As shown in Figure 5 , the first horizontal machining mechanism 431, the first vertical machining mechanism 432, the second horizontal machining mechanism 433 and the second vertical machining mechanism 434 are distributed around the feeding hole.

[0085] As shown in Figure 5 , the fixed clamp includes a support roller A421 connected to the mounting plate 43 and arranged horizontally, the upper space of the support roller A421 is provided with a vertical pressing roller A422, one end of the support roller A421 is provided with a horizontal abutment wheel A423 arranged vertically, and the other end is provided with a horizontal pressing wheel B424.

[0086] As a further embodiment, as shown in Figure 5 , the support roller A421, the vertical pressing roller A422, the horizontal abutment wheel A423 and the horizontal pressing wheel A424 can rotate to contact the profile surface in a rolling friction manner, avoiding scratching the profile surface. Adopting the rotating mode to maintain the clamping force while allowing the profile to move smoothly, avoiding machining errors (such as size deviation or cutting burr) caused by resistance. By rotating to adapt to the curvature of the profile surface, even if the profile has slight warping or tolerance, uniform clamping force distribution can be maintained, avoiding local stress too large causing deformation.

[0087] As a further embodiment, as shown in Figure 5 , the vertical pressing roller A422 is connected to the first pressing cylinder 425, the first pressing cylinder 425 acts in the vertical direction, drives the vertical pressing roller A422 to move towards the direction close to the support roller A421, and presses the profile in the vertical direction.

[0088] As a further embodiment, as shown inFigure 5 As shown, the horizontal pressing wheel A424 is connected to the first horizontal clamping cylinder 426, which acts in the horizontal direction (y direction) to drive the horizontal pressing wheel A424 to move towards the horizontal abutment wheel A423 to clamp the profile from the horizontal direction.

[0089] In the conventional way, the profile is usually clamped in the horizontal direction or the vertical direction. However, the cross-sectional width of the curtain wall profile is larger, and single-direction clamping cannot cope with the vibration problem during processing. Therefore, the profile is clamped from the horizontal direction and the vertical direction to ensure that the influence of vibration on the processing quality is as low as possible.

[0090] As a further embodiment, a second horizontal clamping cylinder 427 can also be provided, which acts in the horizontal direction (y direction) to drive the first horizontal clamping cylinder 426 and the horizontal pressing wheel A424 to move towards the horizontal abutment wheel A423 to clamp the profile. The second horizontal clamping cylinder 427 and the first horizontal clamping cylinder 426 have different action strokes to cope with the clamping of profiles of different widths.

[0091] Due to the width range of the curtain wall profile being much larger than that of the conventional door and window profile, in order to consider stability during processing, the horizontal clamping stroke is preferably greater than the vertical clamping stroke (the processing requirement may be reversed depending on the specific structural requirements of the profile). When clamping, the large-stroke cylinder action requires a certain amount of time. Since both cylinders move in the y direction, they can be segmented and pressed to meet the clamping requirements of profiles of different widths. When clamping profiles of different widths, the two clamping cylinders can act synchronously or sequentially to reduce the stroke requirement and time consumption of each clamping cylinder, thereby saving clamping time and improving processing efficiency.

[0096] The traditional way usually adopts horizontal clamping or vertical clamping to realize fixation, while the cross-section width of the curtain wall profile is larger, and single direction clamping cannot cope with the vibration problem caused during processing, therefore, the profile is clamped from the horizontal direction and the vertical direction at the same time, the profile is clamped from different directions, and the influence of vibration on the processing quality is reduced as much as possible.

[0097] As a further implementation, a fourth horizontal clamping cylinder 4142 can also be arranged, the fourth horizontal clamping cylinder 4142 acts in the horizontal direction (y direction), drives the third horizontal clamping cylinder 4141 and the horizontal pressing wheel B414 to move towards the direction close to the horizontal abutment wheel B413, and clamps the profile from the horizontal direction. The action stroke of the fourth horizontal clamping cylinder 4142 and the third horizontal clamping cylinder 4141 is different, and is used for clamping profiles of different widths.

[0098] During the movement of the profile along the x direction for drilling and milling processing, the follow-up clamp 41 keeps clamping in the state, the pressing point position on the follow-up clamp moves along with the movement direction of the profile through the movement of the sliding plate, and always keeps a stable distance with the processing mechanism, the support effect is better, and the quality of the drilled and milled groove hole is higher.

[0100] As shown in Figures 9-10 The first saw-milling mechanism 53 comprises a base 531 connected to the upper surface of the base 1, the upper surface of the base 531 is provided with an x-direction guide rail 532, the x-direction guide rail 532 is slidingly connected with an x-direction sliding plate 533, the x-direction sliding plate 533 is connected with a z-direction guide rail 539 through a support, the z-direction guide rail 539 is slidingly connected with a z-direction sliding plate 5310, the z-direction sliding plate 5310 is slidingly connected with a y-direction guide rail 5311, the y-direction guide rail 5311 is arranged on a y-direction sliding plate 534, and the y-direction sliding plate 534 is provided with a lateral saw-milling main machine.

[0106] In this embodiment, the swing angle driving mechanism 536 is a motor, which drives the first saw blade 537 to rotate around the y-axis together with the saw blade driving mechanism 538 to realize the swing.

[0107] As shown in Figure 8 , the second saw milling processing mechanism 54 includes a vertical saw milling processing main machine movably connected to the two groups of gantries.

[0110] As a further implementation, the second saw blade 544 is driven by the swing arm driving mechanism 545 to rotate around the y-axis together with the saw blade driving mechanism 546, and the swing arm driving mechanism 545 drives the second saw blade 544 to rotate or swing around the y-axis through the swing arm assembly 543, so that the second saw blade 544 can swing between a horizontal state (0°) and a vertical state (90°), cooperating with the movement in the x, y, and z directions, and the profile is processed by the second saw blade 544.

[0111] In this embodiment, the swing arm driving mechanism 545 is a motor and a transmission mechanism, and the motor drives the second saw blade 544 to rotate around the y-axis together with the saw blade driving mechanism 546 through the transmission mechanism to realize the swing.

[0112] The two sets of saw-milling clamps are arranged in parallel in the space between the two sets of gantries and are connected to the base 1. The two sets of saw-milling clamps clamp the profile from two directions of vertical and horizontal and can move a certain distance along the x direction while keeping clamped, ensuring that the distance between the clamped position and the saw-milling processing position is close enough to obtain better support effect and higher saw-milling processing quality.

[0113] In this embodiment, the first saw-milling clamp 51 and the second saw-milling clamp 52 are the same in technical principle, and the difference is only in the arrangement position of individual components. The structure of the first saw-milling clamp 51 is taken as an example.

[0114] As shown in Figures 13-14 The first saw-milling clamp 51 includes a base 511 connected to the base 1, and the upper surface of the base 511 is provided with a sliding rail 513. The lower surface of the sliding plate 514 is slidably connected with the sliding rail 513. The sliding plate 514 is driven to move along the x direction by the ball screw mechanism 512 provided on the base 511, and the remaining components provided on the sliding plate 514 are driven to move along the x direction.

[0115] As a further embodiment, the base 511 is provided with a ball screw mechanism 512. The motor in the ball screw mechanism 512 is located inside the base 511. The output shaft of the motor is connected with a chain wheel. The chain wheel is connected with a transmission wheel through a chain. The transmission wheel is connected with one end of a screw rod. The screw rod is movably connected with a sliding block. The sliding block is connected with the lower bottom surface of the sliding plate 514. The screw rod is driven to rotate by the motor to drive the sliding block and the sliding plate 514 to move along the x direction.

[0116] As a further embodiment, the upper surface of the sliding plate 514 is provided with a support roller 515 and a fixed roller 5115 arranged in parallel. The space above the support roller 515 is provided with a pressing roller 516. The space above the fixed roller 5115 is provided with a pressing block 5110. The support roller 515 and the fixed roller 5115 are provided with a guide wheel 517 and a horizontal clamping mechanism.

[0117] As a further embodiment, the horizontal clamping mechanism includes a leaning plate 518 arranged on one side of the guide wheel 517. The leaning plate 518 is arranged opposite to a clamping plate 519. The clamping plate 519 is arranged on the side opposite to the leaning plate 518 in the horizontal direction y.

[0118] As a further embodiment, the guide wheel 517 has at least two sets. The two sets of guide wheels 517 are arranged in parallel and vertically on one side of the sliding plate 514. The contact planes formed by the two sets of guide wheels 517 are coplanar with the surface of the leaning plate 518.

[0119] As a further embodiment, the two ends of the compression roller 516 are connected to the corresponding second compression cylinder 5114 through the bracket, the second compression cylinder 5114 acts in the vertical direction, driving the compression roller 516 to move towards the direction close to the support roller 515, and compressing the profile from the vertical direction.

[0120] As a further embodiment, the compression block 5110 is connected to the corresponding first compression cylinder 5113 through the bracket, the first compression cylinder 5113 acts in the vertical direction, driving the compression block 5110 to move towards the direction close to the fixed roller 5115, and compressing the profile from the vertical direction.

[0121] As a further embodiment, in the horizontal clamping mechanism, the clamping plate 519 is driven by the clamping cylinder acting in the horizontal y direction, moving towards the direction close to the back plate 518, and clamping the profile from the horizontal direction.

[0122] As a further embodiment, the horizontal clamping mechanism adopts the form of double-cylinder segmented compression, which is suitable for different width ranges of profiles and saves compression time, improving the efficiency of sawing and milling processing. Specifically, the clamping cylinder includes a first clamping cylinder 5111 and a second clamping cylinder 5112 acting in the horizontal y direction, both groups of clamping cylinders and the clamping plate 519 move along the y direction sliding rail, and the sliding rail is provided with corresponding sliding blocks. The fixed end of the first clamping cylinder 5111 is connected to the sliding block A, and the acting end pushes the clamping plate 519 to move. The fixed end of the second clamping cylinder 5112 is connected to the end of the sliding rail, and the acting end pushes the sliding block B to move together with the sliding block A where the first clamping cylinder 5111 is located. The movement stroke of the two groups of clamping cylinders can be the same or different.

[0123] The width range of curtain wall profiles is much larger than that of conventional door and window profiles. During processing, in order to consider stability, the horizontal clamping stroke is preferably greater than the vertical clamping stroke (the situation may be reversed for some processing requirements, depending on the specific structural requirements of the profile). When clamping, the large-stroke cylinder action requires a certain time. Since the two cylinders move in the y direction, they can achieve segmented compression, which can meet the clamping requirements of profiles with different width ranges. The two clamping cylinders can act synchronously or sequentially, reducing the stroke requirement and time consumption of each clamping cylinder, thereby saving clamping time and improving the efficiency of sawing and milling processing.

[0124] As a further embodiment, the support roller 515, the compression roller 516, and the supporting wheel 517 can rotate to contact the profile surface in a rolling friction manner, avoiding scratching the profile surface. Adopting the rotating mode allows the profile to move smoothly while maintaining the clamping force, avoiding processing errors (such as size deviation or cutting burrs) caused by resistance. By rotating to adapt to the curvature of the profile surface, even if the profile has slight warping or tolerance, uniform clamping force distribution can be maintained, avoiding excessive local stress causing deformation.

[0125] As shown in Figure 15 The fixed roller 5115 is provided with air holes on the surface. By blowing compressed gas into the fixed roller and out of the air holes, the adhesion of aluminum chips on the support roller is solved, and the bottom of the profile is prevented from being scratched. The cross section of the fixed roller is semicircular, the material hardness is lower than the profile, and the surface of the semicircular area is smooth, for example, polypropylene can be used. In terms of structure, the two ends of the semicircular area of the fixed roller are provided with mounting holes for penetrating fasteners to connect the fixed roller to the sliding plate 514. Air pipe joints are provided on the two end faces of the fixed roller for connection with the compressed air source. The air holes are arranged in the semicircular area of the fixed roller and have multiple groups. The multiple groups of air holes are arranged side by side. The planar area of the fixed roller is provided with a strip-shaped groove, the bottom end of the strip-shaped groove is communicated with the air holes, and the two ends are communicated with the air pipe joints.

[0126] The present scheme combines the drilling and milling processing and the sawing and milling processing during the processing of the curtain wall profile in one device. The curtain wall profile is sent into the machining center by the mechanical hand. Through one clamping action, the drilling and milling and the sawing and milling two part processing are completed in sequence or simultaneously. After the processing is completed, the frontmost section of the profile is taken out by the discharge gripper to complete the unloading. Through one clamping process, the precision and efficiency during the processing of the curtain wall profile are improved.

[0127] Example two:

[0128] The working method of the curtain wall profile machining center comprises the following steps:

[0129] The profile is gripped by the mechanical gripper and sent into the drilling and milling processing unit along the X direction until it reaches the set drilling and milling position and is clamped and fixed by the fixed clamp and the follow-up clamp 41. According to the processing requirements, the drilling and milling processing unit feeds from different cross-sectional directions of the profile to perform drilling and milling processing.

[0130] After the drilling and milling processing is completed, the profile continues to move along the X direction in the state that the fixed clamp and the follow-up clamp 41 are clamped and fixed, until it is sent into the sawing and milling unit 5 and is fixed by the first sawing and milling clamp 51 and the second sawing and milling clamp 52. According to the processing requirements, the first sawing and milling processing mechanism 53 and / or the second sawing and milling processing mechanism 54 are used to perform sawing and milling processing on the end of the profile.

[0131] After the sawing and milling processing is completed, the second sawing and milling clamp 52 is loosened, the discharge gripper takes out the frontmost section of the profile by the discharge end gripper and unloads it, and the current processing cycle is ended.

[0132] Specifically:

[0133] The profile is gripped by the mechanical gripper and sent into the drilling and milling processing unit along the X direction until it reaches the set drilling and milling position and is clamped and fixed by the fixed clamp and the follow-up clamp 41. According to the processing requirements, the drilling and milling processing unit feeds from different cross-sectional directions of the profile to perform drilling and milling processing. Figure 1The shown machining center, after the fixed clamp and the follow-up clamp 41 of the drilling and milling processing unit are clamped and fixed, the drilling and milling processing unit body has six drilling and milling processing main machines, which respectively perform drilling and milling processing from the upper, lower, left and right four directions of the profile section (two drilling and milling processing main machines are provided in the upper and lower directions), and each direction of the processing main machine has a movement stroke in x, y and z directions, and can process holes or grooves that meet the process requirement distance, position and angle at one time;

[0134] After the drilling and milling processing is completed, in the state that the fixed clamp and the follow-up clamp 41 are clamped and fixed, the profile is sent to the subsequent sawing and milling unit 5 and is fixed by the first sawing and milling clamp 51 and the second sawing and milling clamp 52. The first sawing and milling processing mechanism 53 and the second sawing and milling processing mechanism 54 can move in x, y and z directions, wherein the lateral sawing and milling main machine in the first sawing and milling processing mechanism 53 can also swing around the y axis, and the vertical sawing and milling main machine in the second sawing and milling processing mechanism 54 can also swing around the y axis and the z axis, so that the sawing and milling processing is performed in the mode that the four-axis and five-axis two sets of sawing and milling main machines are matched;

[0135] After the sawing and milling processing is completed, the second sawing and milling clamp 52 is loosened, and the frontmost profile is taken out by the ejection gripper and is unloaded.

[0136] The first sawing and milling clamp 51 is loosened (or the pressing block 5110 and the clamping plate 519 in the first sawing and milling clamp 51 are loosened, and the pressing roller 516 remains in the pressing state, depending on the length of the remaining profile and the processing requirement of the next cycle), and the remaining profile continues to feed in the x direction in the state that the follow-up clamp 41 and the fixed clamp are clamped and fixed, until it is sent to the sawing and milling unit, and then the two sets of sawing and milling clamps are clamped and fixed, and the sawing and milling processing of the next cycle is started. At this time, according to different processing requirements, the drilling and milling unit and the sawing and milling unit can perform processing at the same time, or can wait until the subsequent profile is sent to the drilling and milling unit before performing drilling and milling processing, until the whole profile blank is consumed or the remaining profile is insufficient to support the next processing task, and then all the clamps are loosened, the remaining profile is taken out by the ejection gripper and is unloaded. The whole process only needs to position the fixed clamp and the follow-up clamp when the profile is in the drilling and milling unit, and the fixed clamp and the follow-up clamp remain clamped during the whole profile blank processing, and only one clamping action is performed.

[0137] The whole process enables the curtain wall profile to complete the required drilling and milling and sawing and milling through one-time clamping, can cope with most of the processing requirements of the curtain wall profile on the surface structure and the end structure, meets the processing quality requirement, and has high efficiency than the traditional way.

[0138] According to the processing requirements of different structures of the profile, the cooperation timing between the drilling and milling unit and the sawing and milling unit is different, and the cooperation timing between the first sawing and milling processing mechanism 53 and the second sawing and milling processing mechanism 54 in the sawing and milling unit is usually different, for example, they can be jointly operated or operated separately, and the structure of a part of the curtain wall profile is taken as an example for introduction.

[0139] The curtain wall profile to be processed in the present scheme is as shown in Figure 16 It can be understood that the curtain wall profile involved in the actual application is not limited to Figure 16 The shape and structure shown in

[0140] The profile end as shown in Figure 17 is processed, two arc grooves located in the upper part are processed by the drilling and milling unit, and the notch located in the lower part is processed by the first sawing and milling processing mechanism 53, and the processing is realized by switching the first saw blade 537 to 90° vertical sawing through the action of 0° horizontal sawing + swing angle driving mechanism 536.

[0141] The profile end as shown in Figure 18 is processed, the profile is sawn by any one of the sawing and milling processing mechanisms, to obtain the profile end face, for example, the second sawing and milling processing mechanism 54 can be used, the two notches located in the upper part of the end face are gradually sawn and milled by the action of the second sawing and milling processing mechanism 54, until the width of the processed notch meets the requirements. The notch located in the lower part of the end face is processed by the first sawing and milling processing mechanism 53, for example, it can be processed by switching the first saw blade 537 to 90° vertical sawing through the action of 0° horizontal sawing + swing angle driving mechanism 536.

[0142] The profile end as shown in Figure 19 is processed, the holes located on the surface of the profile are processed by the drilling and milling unit, and the profile containing the holes is obtained by sawing the profile by the second sawing and milling processing mechanism 54, and the notch part of the profile end face is processed by the action of the second sawing and milling processing mechanism 54. The "milling" method introduced above can be used for processing.

[0143] The drilling and milling processing and the sawing and milling processing during the processing of the curtain wall profile are combined in one device, the curtain wall profile is sent into the machining center by the manipulator, and the drilling and milling and the sawing and milling are completed in sequence or synchronously through one clamping action, and after the processing is completed, the front part of the profile is taken out by the discharge gripper to complete the unloading, and through one clamping process, the precision and efficiency during the processing of the curtain wall profile are improved.

[0144] The above merely provides the preferred embodiments of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the principles and technical scope of the present application shall fall into the scope of the present application.
