Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of profile processing and manufacturing, in particular to a drilling and milling processing unit, a processing center and a working method suitable for curtain wall profiles. BACKGROUND

[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute 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 curtain wall profiles is more than 100 mm, the wall thickness is commonly 2.5-12 mm, or even thicker; the cross-sectional size of conventional door and window profiles is between 50-80 mm, and the wall thickness is between 1.4-2.0 mm.

[0005] During the processing of curtain wall profiles, the profiles need to be clamped and fixed before various processing (such as drilling and milling), and the processing position will fall in the area between the clamping points formed by the two pressing rollers. Due to the high cross-sectional width and thickness of curtain wall profiles, more processing power is usually required, which requires larger processing spindles. When processing profiles with a cross-sectional width greater than a certain size (for example, a cross-sectional width of 150 mm), the distance between the two pressing rollers is usually increased to ensure that the space between the two pressing rollers is large enough to accommodate the processing spindle.

[0006] This way avoids the problem of interference between large-size curtain wall profiles and processing spindles, but the distance between the profile clamping points is too large, and the profile will vibrate under the influence of the processing spindle, affecting the processing quality. For example, during drilling or milling, the profile vibration causes the axis of the drilled hole or milled groove to not meet the requirements for perpendicularity, affecting the subsequent assembly quality; for hinge holes, guide holes or sliding grooves that require high perpendicularity or high flatness, assembly difficulties or movement component jamming may occur. SUMMARY

[0007] To solve the technical problems in the background art, the present application provides a drilling and milling processing unit, a processing center and a working method suitable for curtain wall profiles. In view of the large size and high wall thickness of curtain wall profiles, a follow-up clamp is arranged in front of the drilling and milling processing area to follow the drilling and milling action, so that the profile moves in the feeding direction, ensuring that the current processing position of the profile is as close as possible to the pressing fixed point, and solving the problem of unsatisfactory processing quality caused by the large distance between the profile and the fixed point in the existing way.

[0008] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0014] Further, the first vertical processing mechanism and the second vertical processing mechanism are respectively located on the upper and lower two sides of the profile to be processed, and each has two processing main machines with different power.

[0015] Further, the fixed clamp includes a horizontally arranged supporting roller A, the space above the supporting roller A is provided with a vertical pressing roller A, one end of the supporting roller A is provided with a vertically arranged horizontal abutment wheel A, and the other end is provided with a horizontal pressing wheel B.

[0016] Further, in the follow-up clamp, the upper surface of the slide plate is provided with a supporting roller B, the space above the supporting roller B is provided with a vertical pressing roller B, one end of the supporting roller B is provided with a vertically arranged horizontal abutment wheel B, and the other end is provided with a horizontal pressing wheel B.

[0017] Further, all the supporting rollers, vertical pressing rollers, horizontal abutment wheels and horizontal pressing wheels can rotate.

[0018] Further, the vertical pressing roller A and the horizontal pressing wheel A are connected with the corresponding air cylinder, and under the driving of the respective air cylinder, they clamp the profile to be processed from the vertical direction and the horizontal direction respectively.

[0019] Further, the vertical pressing roller B and the horizontal pressing wheel B are connected with corresponding air cylinders, and under the driving of the respective air cylinders, the profile to be processed is clamped from the vertical direction and the horizontal direction respectively.

[0020] The second aspect of the present application provides a profile machining center, which comprises a base, the upper surface of the base is provided with gantry A and gantry B arranged side by side, the outer side of the gantry A is provided with a drilling and milling unit, and the space between the gantry A and the gantry B accommodates a sawing and milling unit.

[0021] The third aspect of the present application provides a working method of the profile machining center, which comprises the following steps:

[0022] The profile is fed into the drilling and milling processing unit along the x direction, clamped and fixed by the fixed clamp and the follow-up clamp, and the drilling and milling processing is started by using each processing mechanism in the drilling and milling processing unit;

[0023] During the processing, the follow-up clamp moves along the x direction following the target processing mechanism while maintaining the clamping state, and keeps a set distance;

[0025] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0026] 1. In view of the problem of vibration caused by too large distance between clamping points during the machining of curtain wall profiles, a follow-up clamp that moves along with the processing mechanism is provided. The profile to be processed moves along the x direction, passes through the follow-up clamp and the fixed clamp in turn, is clamped and fixed, and then drilling and milling processing is performed. During the preparation for drilling and milling the next section after the drilling and milling of the first section is completed, the follow-up clamp maintains the clamping state and moves along the profile feeding direction to the area required for the next section of processing following the corresponding processing mechanism. During the movement, the follow-up clamp maintains a set distance from the processing mechanism being followed, ensuring that the position of each section of drilling and milling processing is close enough to the position of the clamping and fixing point formed by the follow-up clamp, thereby solving the problem of vibration caused by too large distance between clamping points during processing.

[0027] 2. All the supporting rollers, vertical pressing rollers, horizontal supporting wheels and horizontal pressing wheels can rotate to contact the profile surface in a rolling friction manner, avoiding scratching the profile surface. The use of rotating mode to maintain clamping force allows smooth movement of the profile, 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 deformation caused by excessive local stress.

[0028] 3. The first and second vertical machining mechanisms are located on the upper and lower sides of the profile to be processed, respectively, and each has two machining hosts with different power ratings. The machining hosts can be switched according to the drilling and milling requirements. For example, a higher-powered machining host is used for thicker profiles, significantly improving efficiency; a lower-powered machining host is used for thinner profiles, saving energy and avoiding waste while maintaining efficiency. The upper and lower sides are commonly used machining locations for curtain wall profiles, and having two machining hosts on each side reduces the frequency of tool changes, indirectly improving processing efficiency.

DETAILED DESCRIPTION

[0041] The application will be further described below in conjunction with the drawings and examples.

[0042] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the application. Unless otherwise specified, 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.

[0043] In the following examples, 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.

[0044] Unless specifically designated, "profile" appearing in the following examples refers to "curtain wall profile", i.e. aluminum alloy profile with cross-sectional width exceeding 100 mm and wall thickness greater than 3 mm, for example, a typical curtain wall profile specification is: width 385 mm, height 200 mm, wall thickness 3-12 mm (can be thicker).

[0045] Example 1:

[0046] The drilling and milling processing unit suitable for curtain wall profiles given in this example is arranged in a profile machining center as shown in Figure 1 The base 1 is provided with gantry A2 and gantry B3 arranged side by side on the upper surface of the base 1, 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.

[0047] The drilling and milling processing unit suitable for curtain wall profiles, the overall structure is shown in Figures 2-3 It includes a drilling and milling processing unit body, a fixed clamp and a follow-up clamp 41.

[0048] The profile is gripped by a mechanical gripper and fed into the machining center shown in Figure 1 The profile is gripped by a mechanical gripper and fed into the machining center shown inFigures 2-3 In the drilling and milling unit shown, the material is clamped and fixed by the fixed fixture and the follower fixture 41, and the drilling and milling process begins. After the drilling and milling process is completed, the material is sent to the subsequent sawing and milling unit 5 for sawing and milling according to the processing requirements. After the sawing and milling process is completed, the first section of the profile is taken out and unloaded by the gripper at the discharge end.

[0049] like Figure 4 As shown, the main body of the drilling and milling unit includes a mounting plate 43 connected to the gantry A2. The mounting plate 43 is provided with a feeding hole for accommodating the profile traveling in the x direction, and a fixing fixture is provided in the feeding hole.

[0050] The mounting plate 43 is equipped with a first horizontal machining mechanism 431, a first vertical machining mechanism 432, a second horizontal machining mechanism 433, and a second vertical machining mechanism 434. The four machining mechanisms are used to drill and mill the profile from the four sides of the profile section. Each machining spindle has X, Y, and Z directions of movement under the premise of being able to rotate. The movement in each direction is driven by a ball screw mechanism driven by a motor, thereby ensuring that the machining accuracy meets the requirements.

[0051] As a further implementation method, the specific structure of the four processing mechanisms is not limited. It can be that the motor drives the cutting tool to rotate to form a processing host, and the processing host realizes the movement in the X, Y and Z directions through the bracket and ball screw mechanism. Existing mature structures can be selected.

[0052] This embodiment takes the first vertical machining mechanism 432 as an example to explain the specific structure, including a machining host connected to the cutting tool, the machining host being movably connected to the x-axis slide rail, the x-axis slide rail being connected to the first bracket, the first bracket being movably connected to the z-axis slide rail, the z-axis slide rail being connected to the second bracket, the second bracket being movably connected to the y-axis slide rail, and the y-axis slide rail being arranged on the mounting plate 43.

[0053] The remaining first horizontal machining mechanism 431, second horizontal machining mechanism 433, and second vertical machining mechanism 434 are consistent with the first vertical machining mechanism 432 in principle.

[0054] For example:

[0055] The first horizontal machining mechanism 431 includes a machining host connected to a cutting tool. The machining host is movably connected to an x-axis slide rail. The x-axis slide rail is movably connected to a z-axis slide rail via a slide plate or bracket. The z-axis slide rail is movably connected to a y-axis slide rail via a slide plate or bracket. The y-axis slide rail is arranged on a mounting plate 43.

[0056] The second horizontal machining mechanism 433 comprises a machining host connected with a tool, the machining host is movably connected with an x-direction slide rail, the x-direction slide rail is movably connected with a z-direction slide rail through a slide plate or a support, the z-direction slide rail is movably connected with a y-direction slide rail through a slide plate or a support, and the y-direction slide rail is arranged on the mounting plate 43.

[0057] The second vertical machining mechanism 434 comprises a machining host connected with a tool, the machining host is movably connected with an x-direction slide rail, the x-direction slide rail is movably connected with a z-direction slide rail through a slide plate or a support, the z-direction slide rail is movably connected with a y-direction slide rail through a slide plate or a support, and the y-direction slide rail is arranged on the mounting plate 43.

[0058] As a further embodiment, the first horizontal machining mechanism 431 and the second horizontal machining mechanism 433 are respectively located in the space on both sides of the profile to be machined in the horizontal direction, that is, arranged along the y direction.

[0059] As a further embodiment, the first vertical machining mechanism 432 and the second vertical machining mechanism 434 are respectively located in the space above and below the profile to be machined, and each has two machining hosts with different powers. According to the needs of drilling and milling, the machining hosts with different powers are switched, for example, the profile with thick wall uses the machining host with larger power, which greatly improves the efficiency; the profile with thin wall uses the machining host with smaller power, which can save energy and avoid waste under the premise of meeting efficiency; the machining mechanisms with two machining hosts on the upper and lower sides are commonly used for machining curtain wall profiles, and the machining mechanisms each having two machining hosts also reduce the frequency of changing tools, which indirectly improves the machining efficiency.

[0060] As a further embodiment, the four sets of machining mechanisms have six machining spindles in total, wherein the first vertical machining mechanism 432 and the second vertical machining mechanism 434 each have two machining spindles, the first horizontal machining mechanism 431 and the second horizontal machining mechanism 433 each have one machining spindle, and the four sets of machining mechanisms form a six-machining-spindle arrangement mode.

[0061] 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.

[0062] As shown in Figure 5 and Figure 6 , the fixed clamp comprises a support roller A421 connected to the mounting plate 43 and arranged horizontally, a vertical pressing roller A422 is arranged above the support roller A421, a horizontal abutment roller A423 is arranged vertically at one end of the support roller A421, and a horizontal pressing wheel B424 is arranged at the other end.

[0063] As a further embodiment, as shown inFigure 5 and Figure 6 As shown in FIG. 4A, the support roller A421, the vertical pressing roller A422, the horizontal abutment wheel A423 and the horizontal pressing wheel A424 are all rotatable to contact the profile surface in a rolling friction manner to avoid scratching the profile surface. The rotation mode allows smooth movement of the profile while maintaining the clamping force, avoiding processing errors (such as dimensional deviation or cutting burr) caused by resistance.

[0064] As a further embodiment, as shown in FIG. 4B, the support roller A421, the vertical pressing roller A422, the horizontal abutment wheel A423 and the horizontal pressing wheel A424 are all rotatable to contact the profile surface in a rolling friction manner to avoid scratching the profile surface. The rotation mode allows smooth movement of the profile while maintaining the clamping force, avoiding processing errors (such as dimensional deviation or cutting burr) caused by resistance. Figure 5 and Figure 6 As shown in FIG. 4A, the vertical pressing roller A422 is connected to the first pressing cylinder 425, which acts in the vertical direction to drive the vertical pressing roller A422 to move towards the support roller A421 to press the profile from the vertical direction.

[0065] As a further embodiment, as shown in FIG. 4B, the vertical pressing roller A422 is connected to the first pressing cylinder 425, which acts in the vertical direction to drive the vertical pressing roller A422 to move towards the support roller A421 to press the profile from the vertical direction. Figure 5 and Figure 6 As shown in FIG. 4A, the support roller A421 and the horizontal abutment wheel A423 each have at least two groups arranged side by side, and the vertical pressing roller A422 is not limited in number. The movement axis of the horizontal pressing wheel A424 is located between the two groups of support rollers A421. With this number of configurations, relatively more reliable clamping force can be obtained.

[0066] As a further embodiment, as shown in FIG. 4B, the support roller A421 and the horizontal abutment wheel A423 each have at least two groups arranged side by side, and the vertical pressing roller A422 is not limited in number. The movement axis of the horizontal pressing wheel A424 is located between the two groups of support rollers A421. With this number of configurations, relatively more reliable clamping force can be obtained. Figure 5 and Figure 6 As shown in FIG. 4A, 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.

[0067] Traditional methods usually use horizontal clamping or vertical clamping to achieve fixation, while the cross-sectional width of curtain wall profiles is larger, and single-direction clamping cannot cope with the problem of vibration during processing. Therefore, the profile is clamped from the horizontal and vertical directions, and the profile is clamped from different directions to ensure that the influence of vibration on processing quality is as low as possible.

[0068] 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 together with the horizontal pressing wheel A424 to move towards the horizontal abutment wheel A423 to clamp the profile from the horizontal direction. The action stroke of the second horizontal clamping cylinder 427 and the first horizontal clamping cylinder 426 can be the same or different, which is used to cope with the clamping of profiles of different widths.

[0069] The curtain wall profile has a width range much larger than the conventional door and window profile. In order to consider stability during processing, the stroke of the horizontal clamping is preferably greater than the vertical clamping (the processing requirements may be reversed depending on the specific structural requirements of the profile). When clamping, the large-stroke cylinder action requires a certain time. The double cylinder can realize segmented compression because both cylinders move along the y direction. When dealing with profile clamping requirements of different width ranges, the two clamping cylinders can act synchronously or sequentially, reducing the stroke requirement and action time of each clamping cylinder, thereby saving clamping time and improving processing efficiency.

[0070] The specific structure of the follow-up clamp 41 is shown in Figures 7-8 The upper surface of the base 411 is provided with a guide rail 418 and a ball screw mechanism 416. The guide rail 418 is movably connected with a sliding plate 417, and the sliding block of the ball screw mechanism 416 is connected with the sliding plate 417. A motor is arranged in the base 411, which drives the ball screw mechanism 416 to move and drives the sliding plate 417 to move along the x direction.

[0071] As a further embodiment, the upper surface of the sliding plate 417 is provided with a support roller B412, and the space above the support roller B412 is provided with a vertical compression roller B415. One end of the support roller B412 is provided with a horizontally arranged horizontal abutment wheel B413, and the other end is provided with a horizontal compression wheel B414.

[0072] As a further embodiment, the vertical compression roller B415 is connected with a second compression cylinder 4151, which acts in the vertical direction to drive the vertical compression roller B415 to move towards the support roller B412, thereby compressing the profile from the vertical direction.

[0073] As a further embodiment, the horizontal compression wheel B414 is connected with a third horizontal clamping cylinder 4141, which acts in the horizontal direction (y direction) to drive the horizontal compression wheel B414 to move towards the horizontal abutment wheel B413, thereby clamping the profile from the horizontal direction.

[0074] The traditional method usually adopts horizontal clamping or vertical clamping to realize fixation. However, the cross-sectional 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, which ensures that the influence of vibration on the processing quality is as low as possible.

[0075] As a further embodiment, a fourth horizontal clamping cylinder 4142 can also be provided, which acts in the horizontal direction (y direction) and drives the third horizontal clamping cylinder 4141 together with the horizontal pressing wheel B414 to move towards the horizontal abutment wheel B413, thereby clamping the profile in the horizontal direction. The fourth horizontal clamping cylinder 4142 and the third horizontal clamping cylinder 4141 have different action strokes, which are used to clamp profiles of different widths. Here, similar to the fixed clamp, two sets of clamps that act in the y direction and share the same track are also involved based on the reduction of clamping time.

[0076] As a further embodiment, the support rollers B412 and the horizontal abutment wheels B413 are each provided with at least two sets arranged side by side, and the vertical pressing rollers B415 are not limited in number. The movement axis of the horizontal pressing wheel B414 is located between the two sets of support rollers B412. With this number of configurations, a relatively more reliable clamping force can be obtained.

[0077] During the movement of the profile in the x direction for drilling and milling, the follow-up clamp 41 is kept clamped, and the pressing point on the follow-up clamp moves along with the travel direction of the profile through the movement of the slide plate, and always maintains a stable distance with the machining mechanism, thereby providing better support and obtaining higher quality drilling and milling holes.

[0078] Taking drilling as an example, an initial position is set as 0 position during the movement of the profile in the x direction, which can be the position of the fixed clamp, for example. The distance between the current position to be processed and the 0 position in the x direction is set as A1. The profile is driven by the upstream manipulator to run in the x direction to the area close to the position A1, and then the profile stops moving. The four machining mechanisms (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) in the drilling and milling machining unit body each have the ability to move in the x direction, and each machining mechanism moves in the x direction to the position to be drilled based on the 0 position. At this time, each machining mechanism moves in the x direction in a small range to accurately find the position to be processed. During the movement, the follow-up clamp 41 moves in the x direction along with the machining mechanism, and always maintains a set distance with the machining mechanism, so that during the drilling performed by the machining mechanism, there is always a clamping fixed point within the set range around the drilling position, which can avoid the problem of insufficient drilling accuracy caused by vibration.

[0079] After the hole in position A1 is processed, the profile moves to the vicinity of the next drilling position A2 and stops, the relevant processing mechanism moves to the drilling position A2 along the x direction, the follow-up clamp 41 keeps the clamping state and moves synchronously with the processing mechanism, and a set distance is kept between the follow-up clamp 41 and the processing mechanism. In this way, until the holes in all drilling positions are processed, the follow-up clamp 41, the fixed clamp and the processing mechanisms are reset, and the profile moves to the subsequent sawing and milling unit.

[0080] Since the processing mechanism has four groups, which are respectively used to cope with the processing needs of the profile in different positions, the follow-up clamp 41 can be set to follow one or several processing mechanisms according to the actual processing needs, and the embodiment does not make specific limitations, and the actual drilling and milling processing needs of the profile can be set, and the purpose is to make the follow-up clamp 41 move along the x direction in the state of maintaining clamping and keeping a set distance, and ensure that the clamping influence area of the follow-up clamp 41 can always cover the position of the next processing action.

[0081] For curtain wall profiles, since the wall thickness is much larger than that of conventional door and window profiles, and the cross-sectional structure is more complex, the rigidity is already high enough, and even if a high-power processing host is used due to processing needs, it is also difficult to make it bend. However, since the installation space and movement space of the high-power processing host need to be reserved, the distance between the two clamping points on the curtain wall profile will be larger, which will cause the problem of vibration, and the follow-up clamp 41 moves along the x direction in the state of maintaining clamping, which ensures that the position of each processing action falls into the clamping influence area of the follow-up clamp 41, and can ensure that the influence of vibration on the processing quality is as low as possible.

[0082] For milling processing, based on the same principle, the milling processing has an initial position and an end position, and after the processing mechanism moves to the initial position and the end position along the x direction during the movement, the follow-up clamp 41 moves along the x direction in the state of maintaining clamping, and keeps a set distance.
