Description

Technical Field

[0001] This invention relates to the field of profile processing technology, specifically to a profile end face composite milling machining center and its working method. Background Technology

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

[0003] Aluminum profiles used for door and window mullions have assembly end faces at both ends, which are generally processed through steps such as tenoning, grooving, cutting, and end face milling. During processing, the two ends of the profile can be processed sequentially or simultaneously. However, as the structure of the profile end faces becomes increasingly complex, the processing capacity of existing equipment is limited and cannot meet actual needs. Summary of the Invention

[0004] To address the technical problems mentioned above, this invention provides a composite milling machining center for profile end faces and its working method. Two sets of machining units capable of independent X-axis and Y-axis movement are arranged on a common base. Each machining unit contains four machining hosts, arranged in two layers (or two groups, front and back). Each machining host is capable of X-axis and Z-axis movement, and the two rear-side hosts can rotate around the Y-axis. Through the cooperation of these hosts, the current machining requirements for profile end faces can be greatly met, and machining efficiency can be improved.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The first aspect of the present invention provides a profile end face composite milling machining center, including at least two sets of machining units disposed on a base, the two machining units being symmetrically arranged and moving along the X direction, the X direction being the length direction of the profile to be processed; Each processing unit includes a base, on which a clamp and a column are mounted. The clamp is used to apply clamping force to the profile to be processed. The base is slidably connected to the base and moves along the X direction. The column is slidably connected to the base and moves along the Y direction, where the Y direction is the width direction of the profile to be processed. The column has Z-axis and X-axis movable base plates at different heights on its two sides along the Y direction. One end of each X-axis movable base plate is connected to the corresponding machining host. All machining hosts are located in the area between the column and the fixture. The top of the column has a Z-axis drive mechanism corresponding to the number of machining hosts. Each Z-axis drive mechanism drives the corresponding Z-axis movable base plate, together with the X-axis movable base plate and the corresponding machining host, to move along the Z direction, which is the vertical direction. Each Z-axis movable base plate has an X-axis drive mechanism, which drives the X-axis movable base plate, together with the corresponding machining host, to move along the X direction. The cutting tools or saw blades of each machining host rotate around the Z-axis, and two of the machining hosts located on one side of the column rotate around the Y-axis.

[0006] Furthermore, the fixture includes a horizontally arranged base plate and a vertical clamping plate located in the space above the base plate. Driven by the power module, the vertical clamping plate clamps the profile from a vertical direction.

[0007] Furthermore, a clamping block that moves along the Y direction is provided on one side of the base plate. Driven by the power module, the clamping block clamps the profile in the horizontal direction.

[0008] Furthermore, the base is equipped with an X-axis guide rail, and the base of the processing unit is slidably connected to the X-axis guide rail. It is driven by its respective X-axis main drive unit to achieve movement in the X direction.

[0009] Furthermore, the base is equipped with a Y-guide rail, and the column is slidably connected to the base through the Y-guide rail. The column is driven by the Y-direction main drive unit to achieve movement in the Y direction.

[0010] Furthermore, both the front and rear sides of the column are located in the Y direction, and both the front and rear sides of the column are equipped with processing mechanisms. The processing mechanisms are divided into upper and lower layers of different heights, and each processing mechanism corresponds to at least one processing host.

[0011] Furthermore, the machining host includes an upper machining host A and a lower machining host A located on the front side of the column, and an upper machining host B and a lower machining host B located on the rear side of the column.

[0012] Furthermore, the output shaft of each processing host is connected to a cutting tool or saw blade, and the processing host drives the cutting tool or saw blade to rotate around the Z-axis to achieve processing.

[0013] Furthermore, two of the machining hosts located on one side of the column rotate around the Y-axis. Specifically, the rear side of the column has an upper machining host B and a lower machining host B, and the upper machining host B and the lower machining host B rotate around the Y-axis within a set angle range.

[0014] A second aspect of the present invention provides a method of operating a composite milling machining center for profile end faces, comprising: The two processing units move to their initial positions along the X direction based on the initial length of the profile to be processed; The profile to be processed is fed into the area between the two processing units. After both ends of the profile pass through the clamps of the corresponding processing units and are in the set position, the clamps perform clamping. The processing unit achieves positioning by abutting against the end face of the profile through movement in the X, Y and Z directions. Based on the processing requirements and the positioning position, the processing stroke in the X, Y and Z directions is determined. Each machining host drives the cutting tool or saw blade to rotate around the Z-axis, and performs end face machining using the corresponding machining host according to the determined machining stroke; Once processing is complete, the processing unit is reset, and the feeding mechanism picks up the processed profile and transfers it to the next process.

[0015] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. By arranging two sets of processing units capable of independent X, Y, and Z-axis movements on a common base, the processing mainframes within each unit are divided into upper and lower layers, forming four sets of processing mainframes arranged front and back. Each set of processing mainframes can perform independent X and Z-axis movements, and the upper and lower sets located at the rear can also rotate around the Y-axis. Through the cooperation of all processing mainframes, the current processing requirements for profile end faces can be greatly covered, and the processing of profile end faces can be completed in a single feed motion, improving processing efficiency.

[0016] 2. The machining center features a more compact overall structural layout. Each machining unit uses a column as the main load-bearing element, with the machining host, Z-axis moving base plate, X-axis moving base plate, and X-axis drive mechanism evenly distributed on both sides of the column (Y-direction). This significantly reduces the length of each machining unit in the X-direction, reducing the floor space required, and ensures that the load borne by the column is evenly distributed in the Y-direction, contributing to greater stability and reliability during machining. Simultaneously, the machining host positioned in the front and rear directions of the column allows the corresponding Z-axis drive mechanism to be concentrated at the top of the column, ensuring balanced weight distribution on both sides of the column top and improving stability during milling operations.

[0017] 3. The main processing unit is connected to one end of the X-axis moving base plate, and the X-axis motion mechanism is located in the space at the other end of the X-axis moving base plate. This allows the weight of components such as the X-axis motion mechanism, the X-axis moving base plate, and the Z-axis moving base plate to be evenly distributed in the X direction. This makes the load borne by the column more even and is conducive to more stable and reliable processing.

[0018] 4. When the main processing unit is connected to one end of the X-axis moving base plate, all the main processing units are concentrated in the space between the column and the fixture, making the structure of the entire machining center more compact and enabling better control over the cooperation between the main processing units. When machining complex and precise profile end face structures, the total travel of each main processing unit in different directions can be reduced, lowering the probability of errors and thus improving machining accuracy.

[0019] 5. In addition to moving in the X and Z directions, the two processing main units located at the rear of the column can also rotate around the Y axis at a set angle to process special structures on the end face of the profile, such as inclined tenons or butt grooves. The rear-side location reduces the space occupied on the front side of the column and allows for easy observation of the processing status from the front during processing.

[0020] 6. The entire processing unit moves along the Y-direction. Each processing host does not have its own independent Y-direction motion mechanism. This simplifies the complexity of the processing host's motion mechanism and allows for improved processing efficiency by stacking saw blades when the width of the processed profile ends varies. Taking profile end grooving as an example, the grooving width varies for each profile end, while the saw blade thickness is fixed. The grooving width obtained by one processing host in a single feed action is also fixed. When the processing hosts are arranged along the Y-direction on both sides of the column, the entire processing unit moves along the Y-direction, and the processing hosts on both sides move synchronously. Through the height difference in the Z-direction between the front and rear processing hosts, the saw blades on both sides can synchronously process different heights. That is, a groove twice the thickness of the saw blade can be obtained in a single feed action, thus achieving "stacked grooving" and improving processing efficiency. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. 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 invention pertains.

[0026] Among the processing methods of profiles, "drilling and milling" includes the "drilling" process of using a drill bit to process round holes (through holes or blind holes) on the profile, and the "milling" process of using a rotary milling cutter to cut the surface or edge of the profile to achieve grooving, plane processing, contour forming, etc.

[0027] In profile processing, "sawing and milling" includes "sawing" and "milling." "Sawing" refers to sawing off a portion of the profile, completely separating the profile blank. "Milling" refers to sawing a narrow groove at the end of the profile. For example, if the groove is 8 mm wide and the saw blade is only 4 mm thick, then two "milling" actions are required. At the same time, "sawing and milling" also includes processing the end face of the profile, such as removing burrs or protrusions from the end face.

[0028] In drilling and milling and sawing milling processes, the basic definition of "milling" (i.e., cutting a workpiece using a rotating tool) is the same. The core principle is to use a rotating tool (or saw blade) to remove material and achieve cutting, shaping, or surface finishing. However, the specific application scenarios, processing objectives, and process focuses differ. Milling in drilling and milling is mainly used to process local features such as holes, grooves, and steps (in conjunction with drilling), such as reaming, milling keyways, and chamfering. It is usually used for fine processing of existing holes or local areas, emphasizing its synergy with drilling.

[0029] "Milling" in sawing and milling is mainly used to correct the sawed end face or process the profile outline (in conjunction with sawing, such as correcting the sawed end face, forming the profile interface, opening process grooves, etc., usually for the reprocessing of the overall outline or end face of the sawed profile, emphasizing the complementarity with sawing).

[0030] In this design, the length direction of the profile is taken as the x-axis or x-direction, the width direction as the y-axis or y-direction, and the height direction as the z-axis or z-direction, with the three directions being perpendicular to each other.

[0031] Unless otherwise specified, the term "profile" in the following examples refers to aluminum alloy profiles used in the manufacture of doors and windows.

[0032] The following embodiments provide a composite milling machining center for profile end faces and its working method. Two sets of machining units capable of independent X-axis and Y-axis movement are arranged on a common base. Each set of machining units has four machining hosts, which are arranged in two layers to form front and rear groups. Each machining host can move in both the X and Z axes, and the two hosts located at the rear can rotate around the Y-axis. Through the cooperation of each host, the machining needs of the profile end faces can be greatly covered, and the machining efficiency can be improved.

[0033] Example 1: like Figure 1 and Figure 2 As shown, the profile end face composite milling machining center includes machining unit A1 and machining unit B3 slidably connected to the base 2, and a control unit 4 is provided at one end of the base 2.

[0034] The two processing units are symmetrically structured, each including an outer protective cover, a clamping device inside the outer cover, and multiple processing main units. The profile to be processed is fed into the space between the two processing units using a feeding mechanism such as a gripper or robotic arm. According to the predetermined profile dimensions, the two processing units move closer to each other until both ends of the profile pass through the clamping areas inside the corresponding processing units and reach the processing area. The clamping device then clamps the profile, and the two processing units process the ends of the profile according to the processing requirements. After processing is completed, the clamping device releases, the two processing units move away from each other and reset, and the profile is removed by the feeding mechanism.

[0035] The base 2 is equipped with an X-axis guide rail, and both processing units are slidably connected to the X-axis guide rail. They are driven by their respective X-axis main drive units 119 to achieve movement in the X direction.

[0036] The two sets of processing units have symmetrical structures. In this embodiment, the structure of processing unit B3 is taken as an example.

[0037] like Figures 3-5 As shown, the processing unit B3 includes a base 100 slidably connected to the base 2. The base 100 is provided with a clamp 102 and a Y-guide rail 101. The base 100 is slidably connected to the column 112 through the Y-guide rail 101.

[0038] The fixtures 102 in the two machining units are located on opposite sides, such as... Figure 3 As shown, the clamp 102 includes a horizontally arranged base plate and a vertical clamping plate located in the space above the base plate. The vertical clamping plate clamps the profile from the vertical direction under the drive of the power module (such as a cylinder).

[0039] One side of the base plate is also equipped with a clamping block that moves along the horizontal direction (Y direction). The clamping block is driven by a power module (such as a cylinder) to clamp the profile in the horizontal direction.

[0040] The fixture 102 is located on one side of the column 112. Machining mechanisms are provided on both the front and rear sides of the column 112, and these mechanisms are divided into upper and lower layers. Each machining mechanism corresponds to a machining host, including an upper machining host A104 and a lower machining host A103 located on the front side of the column 112, and an upper machining host B105 and a lower machining host B122 located on the rear side of the column 112. Each machining host can move in both the X and Z directions under the cooperation of the guide rail and the drive mechanism. Simultaneously, the two machining hosts located on the rear side (upper machining host B105 and lower machining host B122) can rotate around the Y-axis. After the fixtures 102 of the two machining units clamp the profile together, the two ends of the profile are milled using the machining hosts in their respective machining units.

[0041] The Y-axis main drive unit 114 mounted on the column 112 drives the column 112 and the machining mechanism on the column 112 to move along the Y direction. In this embodiment, the Y-axis main drive unit 114 is located on one side of the column 112, such as... Figure 3 As shown. The structure of the Y-axis main drive unit 114 is not limited. For example, in this embodiment, the Y-axis main drive unit 114 includes a drive motor, a drive gear is connected to the output shaft of the drive motor, the drive gear meshes with a rack, and the rack is connected to the Y-axis guide rail 101.

[0042] In this scheme, the entire processing unit moves along the Y-direction. Each processing host does not have an independent Y-direction motion mechanism. Instead, it uses stacked saw blades to improve processing efficiency when the processing width at the profile end varies. Taking profile end grooving as an example, since the grooving width at the end of each profile is different, while the saw blade thickness is fixed, the grooving width obtained by one feeding action of a processing host is also fixed. The processing hosts are arranged along the Y-direction on the front and rear sides of the column. When the entire processing unit moves along the Y-direction, the processing hosts on the front and rear sides move synchronously. Through the height difference in the Z-direction between the front and rear processing hosts, the saw blades on both sides can synchronously process different heights. That is, a groove twice the thickness of the saw blade can be obtained with one feeding, thus achieving "stacked grooving".

[0043] For example, to machine a 10mm wide groove, one saw blade milling cutter at the front of the column mills 5mm, and another saw blade milling cutter at the rear of the column mills an additional 5mm. The two saw blades have a height difference (pre-adjusted). Through a single synchronized Y-axis feed motion of both saw blades, a 10mm groove is machined on the end face of the profile in one operation. If the profile is rectangular and the saw blade size matches the profile size, both ends can be machined at once, depending on the specific dimensions of the profile and saw blades and the processing requirements.

[0044] Using the traditional method, a 10mm groove requires two feed actions with a 5mm saw blade, and the height needs to be adjusted between the two feeds, which slows down efficiency in assembly line production. This solution, with the structure described above, can accelerate the production cycle.

[0045] The column 112 is also equipped with an X-axis main drive unit 119, such as Figure 4 As shown, the X-axis main drive unit 119 drives the column 112 and four sets of processing mechanisms to achieve movement in the X direction. By controlling the X-axis main drive unit 119, the two sets of processing units can be moved closer to each other, further apart, or in the same direction. In this embodiment, the X-axis main drive unit 119 includes a drive motor, and a drive gear is connected to the output shaft of the drive motor. The drive gear meshes with a rack, and the rack is connected to the X-axis guide rail on the base 2.

[0046] The column 112 has Z-axis guide rails 113 on both its front and rear sides. Each set of Z-axis guide rails 113 is slidably connected to two sets of vertically arranged Z-axis moving base plates 121. Each set of Z-axis moving base plates 121 is slidably connected to a corresponding X-axis moving base plate 120 via X-axis guide rails. Each set of X-axis moving base plates 120 is equipped with a corresponding machining host. This structure makes the weight of the column 112 more balanced on both sides. Figure 5 As shown. For ease of understanding, Figure 5Some components of the X-axis drive mechanism C115 and the X-axis moving base plate 120 corresponding to the X-axis drive mechanism C115 are hidden to show the relative positional relationship between the column 112, the X-axis moving base plate 120 and the Z-axis moving base plate 121.

[0047] The top of the column 112 is equipped with four sets of Z-axis drive mechanisms. Each set of Z-axis drive mechanisms drives the corresponding Z-axis moving base plate 121 together with the X-axis moving base plate 120 and the corresponding machining host to move vertically along the Z-direction, which is used to adjust the machining height position and feed stroke.

[0048] In this embodiment, the four Z-axis drive mechanisms include Z-axis drive mechanism A106, Z-axis drive mechanism B107, Z-axis drive mechanism C108, and Z-axis drive mechanism D109. Z-axis drive mechanisms A106 and B107 are located on the front side of the top of the column 112, driving the upper machining host A104 and the lower machining host A103 to move along the Z-axis direction, respectively. Correspondingly, Z-axis drive mechanisms C108 and D109 are located on the rear side of the top of the column 112, driving the upper machining host B105 and the lower machining host B122 to move along the Z-axis direction, respectively.

[0049] In this embodiment, the Z-axis drive mechanism includes a drive motor. The output shaft of the drive motor is connected to the corresponding Z-axis moving seat plate through a lead screw and slider mechanism. The lead screw in the lead screw and slider mechanism are arranged in parallel with the Z-axis guide rail 113 on the column 112. The slider in the lead screw and slider mechanism is connected to the Z-axis moving seat plate.

[0050] Each Z-axis moving base plate 121 is equipped with a corresponding X-axis driving mechanism. The X-axis driving mechanism drives the X-axis moving base plate 120 together with the corresponding machining host to move horizontally along the X direction, which is used to adjust the horizontal position and feed stroke during processing.

[0051] In this embodiment, there are four sets of X-axis drive mechanisms, which are respectively connected to the Z-axis moving base plate corresponding to each processing host. They include X-axis drive mechanisms A116 and B111 located on the front side of the column 112, and X-axis drive mechanisms C115 and D110 located on the rear side of the column 112.

[0052] In this embodiment, the X-axis drive mechanism includes a drive motor. The output shaft of the drive motor is connected to the corresponding X-axis moving base plate through a lead screw and slider mechanism. The lead screw in the lead screw and slider mechanism are arranged in parallel with the X-axis guide rail on the surface of the Z-axis moving base plate. The slider in the lead screw and slider mechanism is connected to the X-axis moving base plate.

[0053] Each set of X-axis moving base plates 120 is equipped with a corresponding machining host. Specifically, the machining host is located at one end of the corresponding X-axis moving base plate, and all machining hosts are located in the area between the column 112 and the fixture 102, so that the machining hosts in the two sets of machining units are located on the side that is close to each other.

[0054] The machining host has rotating cutting tools or saw blades, and the cutting tools or saw blades in each set of machining hosts rotate around the Z-axis to perform machining. The two sets of machining hosts located behind the column 112 can also rotate around the Y-axis within a set angle range (e.g., 0-120°) to process profile end faces at specific angles (e.g., grooves, tenons, and bevel cuts). A positioning mechanism (e.g., a positioning plate) is provided on the front side of the column 12 to determine the position of the profile end face during machining. The presence of the positioning plate will affect the rotation of the two sets of machining hosts in front of the column 12 around the Y-axis. Therefore, the function of rotating around the Y-axis is set in the two sets of machining hosts located behind the column 112 to avoid motion interference.

[0055] The machining center described above utilizes two sets of machining units arranged independently in the X and Y directions on a common base. These units are symmetrically structured, with each set containing four machining centers arranged in two layers, forming front and rear groups. Each machining center is capable of X and Z-axis movement, and the two rear machining centers can also rotate around the Y-axis. Through the coordinated operation of these machining centers, the machining capabilities can be significantly expanded to meet current requirements for profile end faces, completing the machining process in a single feed motion, thus improving processing efficiency.

[0056] For example, the left and right processing units select different cutting tools or saw blade combinations for processing according to the tenon size requirements of different profiles. By controlling each drive mechanism, multiple sets of saw blade combinations are used for milling and cutting, so as to quickly complete the milling processing of tenons of various widths and depths at the splicing ends of aluminum profiles for doors and windows. Figure 6 As shown. Since most of the ends of the profile are grooved, it is designed as two processing units, left and right, to process simultaneously. The saw blades of each host are centrally arranged to facilitate milling by stacking thicker saw blades.

[0057] Example 2: The working method of the profile end face composite milling machining center includes the following steps: The two processing units move to their initial positions along the X direction based on the initial length of the profile to be processed; The profile to be processed is fed into the area between the two processing units. After both ends of the profile pass through the clamps of the corresponding processing units and are in the set position, the clamps perform clamping. The processing unit achieves positioning by abutting against the end face of the profile through movement in the X, Y and Z directions. Based on the processing requirements and the positioning position, the processing stroke in the X, Y and Z directions is determined. Each machining host drives the cutting tool or saw blade to rotate around the Z-axis, and performs end face machining using the corresponding machining host according to the determined machining stroke; Once processing is complete, the processing unit is reset, and the feeding mechanism picks up the processed profile and transfers it to the next process.

[0058] In this embodiment, the two processing units move to the corresponding positions according to the profile length index, and the profile to be processed is placed in the fixture of each processing unit; the end positioning plate presses against the end face of the profile to achieve positioning, and after positioning, the fixture moves to clamp.

[0059] The positioning plate in this embodiment is a mature technology. This solution does not elaborate on the specific location of the positioning plate, as long as it can achieve the positioning of the end of the profile.

[0060] After the profile is clamped, the eight saw blade milling cutters in the two processing units cooperate with each other to perform end face milling according to the processing technology of the profile end face; the simultaneous participation of the eight saw blade milling cutters maximizes the end face milling efficiency.

[0061] After the profile end face is processed, the clamps can be released to remove the processed profile.

[0062] The two processing units repeat the motion process described above to perform end milling on the next profile.

[0063] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

Specifically, the rear side of the column has an upper machining host B and a lower machining host B, and the upper machining host B and the lower machining host B rotate around the Y-axis within a set angle range.

10. The working method of the profile end face composite milling machining center according to any one of claims 1-9, characterized in that, Includes the following steps: The two processing units move to their initial positions along the X direction based on the initial length of the profile to be processed; The profile to be processed is fed into the area between the two processing units. After both ends of the profile pass through the clamps of the corresponding processing units and are in the set position, the clamps perform clamping. The processing unit achieves positioning by abutting against the end face of the profile through movement in the X, Y and Z directions. Based on the processing requirements and the positioning position, the processing stroke in the X, Y and Z directions is determined. Each machining host drives the cutting tool or saw blade to rotate around the Z-axis, and performs end face machining using the corresponding machining host according to the determined machining stroke; Once processing is complete, the processing unit is reset, and the feeding mechanism picks up the processed profile and transfers it to the next process.
