Description

Technical Field

[0001] The invention mainly relates to the field of comprehensive processing of aluminum profiles, and in particular to a comprehensive processing device for aluminum profiles of metal door and window frames. Background Art

[0002] Aluminum profiles have good wind pressure resistance, good flame retardancy, light weight and high strength. They have gradually replaced wooden structures and been used in the door and window industry. When processing aluminum profiles for doors and windows, it is usually necessary to complete the fixing of the aluminum profiles, use a drilling machine to complete the drilling processing around the aluminum profiles, and use a milling machine to complete the milling and tenoning processing at both ends of the aluminum profiles, so as to facilitate the subsequent overall installation. The positioning before processing usually requires the production of different tooling, and the positioning is completed manually before the automatic or semi-automatic drilling and milling operations are performed. This processing method is relatively primitive and still requires manual material transportation, loading and unloading, and positioning operations. There are many uncertain factors in the processing process. In addition, this processing method is to complete the overall aluminum profile processing through the two separate processes of drilling and milling. The aluminum profile positioning and clamping needs to be performed twice during the processing process. The separation of the process makes the overall processing time longer. The above problems in the processing lead to a low degree of automation, high processing costs, and low processing efficiency in the processing of aluminum profiles for doors and windows. Summary of the invention

[0003] In order to solve the deficiencies of the prior art, the present invention provides a comprehensive processing device for metal door and window frame aluminum profiles, which can combine drilling and milling processes, has a high degree of automation, reduces processing costs, and improves processing efficiency.

[0004] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0005] A comprehensive processing device for aluminum profiles of metal door and window frames, comprising a feeding device, a base and a receiving device, a longitudinal displacement track and a longitudinal screw mechanism are arranged on the top of the base, an operating table is slidably arranged on the longitudinal displacement track, a sliding pair slidably matched with the longitudinal displacement track and a screw nut matched with the longitudinal screw mechanism are arranged at the bottom of the operating table, a transverse displacement track and two groups of transverse screw mechanisms are arranged on the top of the operating table, the two groups of transverse screw mechanisms are symmetrically arranged between the two transverse displacement tracks, a main clamp seat and a sub-clamp seat are slidably arranged on both sides of the transverse displacement track, the main clamp seat and the sub-clamp seat respectively correspond to one of the transverse screw mechanisms, inner rings are rotatably arranged in the main clamp seat and the sub-clamp seat, a rotating servo drive mechanism for driving the inner ring to rotate is arranged on the main clamp seat and the sub-clamp seat, and four A main clamping cylinder, a main clamping head is arranged at the front end of the piston rod of the main clamping cylinder, and a main positioning piece is arranged on the piston rods of at least two groups of adjacent main clamping cylinders, and four auxiliary clamping cylinders are evenly arranged in a circle on the inner ring in the auxiliary clamp seat, and an auxiliary clamping head is arranged at the front end of the piston rod of the auxiliary clamping cylinder, and auxiliary positioning pieces are arranged on the piston rods of at least two groups of adjacent auxiliary clamping cylinders. A limit table is arranged on the inner ring, which corresponds to the main positioning piece and the auxiliary positioning piece in a one-to-one manner. The feeding device is arranged at the front end of the base close to the main clamp seat, and the material receiving device is arranged at the rear end of the base close to the auxiliary clamp seat. Milling machines are arranged on both sides of the base, a transverse frame is arranged above the base, a transverse rail and a transverse servo drive mechanism are arranged on the top of the transverse frame, a transverse seat driven by the transverse servo drive mechanism is slidably arranged on the transverse track, an extension arm is arranged on the transverse seat, and a drilling head is arranged at the bottom of the extension arm.

[0006] The present invention receives the aluminum profile through the operating table and serves as a processing table for the aluminum profile. The present invention combines the drilling and milling processes of the aluminum profile, and can complete the processing of the two processes after one-time clamping, thereby reducing the transfer time between the two processes and improving the processing efficiency.

[0007] The present invention can complete the loading, positioning and unloading operations of aluminum profiles through the coordinated movement of the main clamp seat and the auxiliary clamp seat, so that the overall processing process of the aluminum profiles can be completed automatically, which greatly improves the processing efficiency, reduces the degree of human participation, and reduces the processing cost.

[0008] The present invention also drives the aluminum profile to rotate by rotating the inner ring, so that each processing surface is exposed upward, thereby facilitating drilling and milling operations on each surface of the aluminum profile and improving the overall processing efficiency.

[0009] An annular inner cavity is provided inside the main clamp seat and the auxiliary clamp seat, the inner ring is connected to the annular inner cavity bearing, the width of the inner ring is greater than the bearing width, one side of the inner ring has ring teeth, and the output gear of the rotating servo drive mechanism is meshed with the ring teeth.

[0010] By rotating the servo drive mechanism to stably drive the inner ring, the stable flipping of the aluminum profile can be guaranteed, so that the various sides of the aluminum profile can be stably presented on the top, ensuring the drilling processing of the various sides of the aluminum profile.

[0011] The width of the main positioning plate is smaller than the width of the main clamping head, the width of the auxiliary positioning plate is smaller than the width of the auxiliary clamping head, and the limit platform includes two inverted L-shaped limit frames arranged opposite to each other. The width between the two L-shaped limit frames is larger than the width of the main clamping head and the auxiliary clamping head, and smaller than the width of the main positioning plate and the auxiliary positioning plate.

[0012] The limit table cooperates with the main positioning plate and the auxiliary positioning plate, so that one side and one bottom edge of the aluminum profile can be positioned when clamping, thereby completing the positioning of the aluminum profile in the horizontal and height directions, making the drilling and milling operations of the aluminum profile more accurate.

[0013] The L-shaped limiting frame comprises a limiting support rod vertically arranged on the side of the inner ring and a limiting plate vertically arranged with the limiting support rod, and the installation height of the limiting plate on the limiting support rod is adjustable.

[0014] The height-adjustable limit table structure can adapt to aluminum profiles of different sizes.

[0015] The main clamping head is a plane clamping head, and the auxiliary clamping head is a roller clamping head.

[0016] The planar structure of the main clamping head can ensure stable clamping of the aluminum profiles. The rotatable roller-type auxiliary clamping head makes the conveying and positioning of the aluminum profiles smoother. At the same time, after the auxiliary clamping head clamps, it cooperates with the main clamping head to ensure the stability of the clamping.

[0017] The feeding device includes a feeding rack, a feeding roller is arranged on the top of the feeding rack, a feeding power mechanism for driving the feeding roller is arranged on one side of the feeding rack, and a plurality of pairs of limit devices are arranged in an array on both sides of the feeding rack. When the aluminum profile is conveyed to a corresponding distance beyond the end of the feeding rack, the feeding roller stops the conveying action.

[0018] The material receiving device comprises a material receiving frame, and a conveying mechanism is arranged on the material receiving frame.

[0019] The feeding device and the receiving device cooperate with the main clamping head to complete the reception and feeding of the aluminum profiles, making the entire processing process more continuous and ensuring the smooth processing of aluminum alloy and aluminum profiles.

[0020] Two opposing main clamping cylinders among the four main clamping cylinders form a group, and the two groups of main clamping cylinders are arranged in a front-to-back position relationship within the inner ring; two opposing auxiliary clamping cylinders among the four auxiliary clamping cylinders form a group, and the two groups of auxiliary clamping cylinders are arranged in a front-to-back position relationship within the inner ring.

[0021] The main clamping cylinder and the auxiliary clamping cylinder are arranged in a front-to-back position relationship, so that when the main clamping head and the auxiliary clamping head clamp the aluminum profile, there will be no interference with each other, so that the length of the main clamping head and the auxiliary clamping head can be smoothly increased, so that the clamping effect on the aluminum profile is better.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] Compared with the existing processing technology, the present invention has a higher degree of automation and greatly reduces the degree of human involvement. Through automated processing, the drilling and milling processes are combined, thereby reducing the aluminum profile transfer, positioning and other processes, saving processing time and improving processing efficiency.

DETAILED DESCRIPTION

[0031] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the application.

[0032] like Figure 1-6 As shown, the metal door and window frame aluminum profile comprehensive processing device of the present invention comprises a feeding device 5, a base 1 and a receiving device 6, wherein the base 1 is used as the installation position of various components received by the aluminum alloy door and window aluminum profile. The feeding device 5 continuously feeds the aluminum profile, and the receiving device 6 relays the aluminum profile after processing to complete the subsequent transportation of the aluminum profile.

[0033] A longitudinal displacement track 11 and a longitudinal lead screw mechanism 12 are arranged on the top of the base 1, an operating table 2 is slidably arranged on the longitudinal displacement track 11, and a sliding pair slidably matched with the longitudinal displacement track 11 and a lead screw nut matched with the longitudinal lead screw mechanism 12 are arranged at the bottom of the operating table 2. The longitudinal lead screw mechanism 12 is driven by a servo motor, and the operating table 2 can be driven to stably displace in the longitudinal direction through the drive of the longitudinal lead screw mechanism 12. A transverse displacement track 21 and two sets of transverse lead screw mechanisms 22 are arranged on the top of the operating table 2, and the two sets of transverse lead screw mechanisms 22 are symmetrically arranged between the two transverse displacement tracks 21. A main clamp seat 23 and a sub-clamp seat 24 are slidably arranged on both sides of the transverse displacement track 21, and the main clamp seat 23 and the sub-clamp seat 24 correspond to one of the transverse lead screw mechanisms 22 respectively, so that the main clamp seat 23 and the sub-clamp seat 24 are driven respectively by the two sets of transverse lead screw mechanisms 22. By driving two sets of transverse screw mechanisms 22 separately, the main clamp seat 23 and the auxiliary clamp seat 24 can be driven to move separately, so that the main clamp seat 23 can pull the aluminum profile to complete loading and unloading and positioning operations under the limit of the auxiliary clamp seat 24.

[0034] The feeding device 5 is arranged at the front end of the base 1 near the main clamp seat 23. The feeding device 5 includes a feeding rack 51, a feeding roller 52 is arranged in an array on the top of the feeding rack 51, and a feeding power mechanism for driving the feeding roller 52 is arranged on one side of the feeding rack 51. A plurality of pairs of limit devices are arranged in arrays on both sides of the feeding rack 51. The limit device limits the conveying direction of the aluminum profile to prevent the aluminum profile from deviating from the conveying track. The feeding roller 52 conveys the aluminum profile by its own rotation, so that the aluminum profile can be transferred to a position waiting for the main clamp seat 23 to clamp it. Specifically, a position sensor is installed on the front side of the feeding rack 51. When the aluminum profile is conveyed to a corresponding distance beyond the end of the feeding rack 51, the position sensor will be triggered, and the position sensor will transmit the signal to the controller, and the controller will control the feeding power mechanism to stop running, so that the feeding roller 52 stops the conveying action. At this time, the extended part of the aluminum profile is captured by the main clamp seat 23, and the main clamp seat 23 drives the aluminum profile to approach the auxiliary clamp seat 24. After the aluminum profile is placed on the auxiliary clamp seat 24 and clamped, the main clamp seat 23 and the auxiliary clamp seat 24 move away from each other, thereby completing the clamping of the two ends of the aluminum profile. The operating table 2 is located on one side of the auxiliary clamp seat 24 and is installed with several groups of positioning sensors, which are used to detect one end of the aluminum profile. When positioning the aluminum profile, the auxiliary clamp seat 24 slightly loosens the clamping of the aluminum profile, and the aluminum profile is clamped by the main clamp seat 23 and moved to the side of the auxiliary clamp seat 24 until the aluminum profile triggers the positioning sensor, and then the auxiliary clamp seat 24 is clamped, and the main clamp seat 23 slightly loosens the clamping and resets to the clamping position to continue clamping the aluminum profile, at which time the drilling position on the aluminum profile is exposed. When milling and tenon processing is required on both ends of the aluminum profile, the longitudinal screw mechanism 12 drives the operating table 2 to move to the milling processing position, and through the synchronous displacement of the main clamp seat 23 and the auxiliary clamp seat 24, the two ends of the aluminum profile can be sent to the milling cutter position, thereby completing the milling and tenon processing on both ends of the aluminum profile.

[0035] The receiving device 6 is arranged at the rear end of the base 1 near the side of the auxiliary fixture seat 24, and the receiving device 6 includes a receiving frame 61, and a conveying mechanism 62 is arranged on the receiving frame 61. The conveying mechanism 62 can select a belt conveying mechanism or a roller conveying mechanism, so as to receive the processed aluminum profiles and convey the aluminum profiles to the assembly process.

[0036] Through the cooperation of the feeding device 5 and the receiving device 6 with the main clamp seat 23 and the auxiliary clamp seat 24, the automatic reception of aluminum profiles can be completed. The whole process requires almost no human participation, and the automatic loading and unloading, positioning, drilling and milling of aluminum profiles can be completed, which greatly improves the processing efficiency.

[0037] In order to achieve good drilling processing on the sides of the aluminum profile and correspondingly complete the milling and tenon processing at both ends, the main clamp seat 23 and the auxiliary clamp seat 24 of the device are both rotatably provided with an inner ring 25. The main clamp seat 23 and the auxiliary clamp seat 24 are both installed with a rotating servo drive mechanism 26 for driving the inner ring 25 to rotate. Specifically, an annular inner cavity is provided on the inner side of the main clamp seat 23 and the auxiliary clamp seat 24, and the inner ring 25 is connected to the annular inner cavity bearing. The width of the inner ring 25 is greater than the width of the bearing. One side of the inner ring 25 has a ring tooth, and the side of the inner ring 25 without the ring tooth is interference fit with the inner ring of the bearing. The rotating servo drive mechanism 26 adopts a combination of a servo motor and a gear reducer. The rotating shaft of the servo motor is coaxially connected with the input shaft of the gear reducer, and the output gear of the gear reducer is meshed with the ring tooth. Driven by the servo motor, the inner ring 25 can be driven to rotate accurately, thereby ensuring that each processing surface of the aluminum profile is in a horizontal state, and the hole processing of the aluminum profile is completed in cooperation with the drilling processing device.

[0038] Specifically, the main clamp seat 23 and the auxiliary clamp seat 24 complete the processing of the aluminum profile through the following structure. Four main clamping cylinders 31 are evenly arranged on the inner ring 25 in the main clamp seat 23, and a main clamping head 32 is arranged at the front end of the piston rod of the main clamping cylinder 31. The main clamping head 32 is a flat clamping head, which can stably clamp the aluminum profile. Four auxiliary clamping cylinders 41 are evenly arranged on the inner ring 25 in the auxiliary clamp seat 24, and an auxiliary clamping head 42 is arranged at the front end of the piston rod of the auxiliary clamping cylinder 41. The auxiliary clamping head 42 is a roller clamping head. The auxiliary clamping head 42 can rotate, so that when the main clamp seat 23 clamps the aluminum profile and feeds it to the auxiliary clamp seat 24, the auxiliary clamping head 42 can reduce the friction between the aluminum profile and the auxiliary clamping head, so as to ensure smoother movement of the aluminum profile during loading, unloading and positioning.

[0039] A main positioning piece 33 is provided on the piston rod of at least two adjacent groups of main clamping cylinders 31, and a secondary positioning piece 43 is provided on the piston rod of at least two adjacent groups of secondary clamping cylinders 41. A limiting platform 27 is provided on the inner ring 25, which corresponds to the main positioning piece 33 and the secondary positioning piece 43. Specifically, the width of the main positioning piece 33 is smaller than the width of the main clamping head 32, and the width of the secondary positioning piece 43 is smaller than the width of the secondary clamping head 42. The limiting platform 27 includes two inverted L-shaped limiting frames arranged opposite to each other, and the width between the two L-shaped limiting frames is larger than the width of the main clamping head 32 and the secondary clamping head 42, and smaller than the width of the main positioning piece 33 and the secondary positioning piece 43. When the main clamping cylinder 31 and the secondary clamping cylinder 41 are extended, the main positioning piece 33 and the secondary positioning piece 43 will be limited by the L-shaped limiting frame, thereby completing the positioning of the aluminum profile in the up and down and left and right directions.

[0040] Furthermore, the L-shaped limit frame includes a limit support rod 271 vertically arranged on the side of the inner ring 25 and a limit plate 272 vertically arranged with the limit support rod 271, and the installation height of the limit plate 272 on the limit support rod 271 is adjustable. Specifically, the limit support rod 271 has a long groove, and the limit support rod 271 is fastened in the long groove by bolts, so as to facilitate the position adjustment of the limit plate 272, so that the L-shaped limit frame can adapt to the positioning processing of aluminum alloy aluminum profiles of different sizes.

[0041] Milling machines 7 are arranged on both sides of the base 1. The operating table 2 is driven to move longitudinally through the longitudinal screw mechanism 12, so that the aluminum profile can be adjusted to be parallel to the milling machine 7. Then, the main clamp seat 23 and the auxiliary clamp seat 24 are linked to drive the aluminum profile to extend to the processing position of the milling machine 7, and the milling cutter completes the milling operation at both ends of the aluminum profile.

[0042] A transverse frame 8 is arranged above the base 1, a transverse track 81 and a transverse servo drive mechanism 82 are arranged on the top of the transverse frame 8, and a transverse seat 83 driven by the transverse servo drive mechanism 82 is slidably arranged on the transverse track 81. The transverse servo drive mechanism 82 adopts a synchronous belt mechanism or a screw mechanism, and its power mechanism adopts a servo motor, so as to drive the transverse seat 83 to move to any position on the transverse track 81. An extension arm 84 is arranged on the transverse seat 83, and a drilling head 85 is arranged at the bottom of the extension arm 84. Specifically, the extension arm 84 is driven by the vertical screw drive mechanism, so as to drive the drilling head 85 thereunder to extend, and the drilling head 85 completes the processing of the hole position. Specifically, when processing the mounting hole, it is only necessary to drive the transverse seat 83 to move to the punching position of the aluminum profile by the transverse servo drive mechanism 82, and the extension arm 84 can complete the drilling processing of the aluminum profile by the drilling head 85. When processing the long hole on the aluminum profile, it is necessary to cooperate with the driving of the lateral servo drive mechanism 82 during drilling to complete the processing of the long hole. If the width of the long hole exceeds the diameter of the drill bit, it is necessary to cooperate with the driving of the longitudinal screw mechanism 12 at the same time to realize the processing in the width direction of the long hole.

[0043] Two opposing main clamping cylinders 31 of the four main clamping cylinders 31 form a group, and the two groups of main clamping cylinders 31 are arranged in a front-to-back position relationship in the inner ring 25. Two opposing auxiliary clamping cylinders 41 of the four auxiliary clamping cylinders 41 form a group, and the two groups of auxiliary clamping cylinders 41 are arranged in a front-to-back position relationship in the inner ring 25. The main clamping cylinders 31 and the auxiliary clamping cylinders 41 arranged in a front-to-back position relationship can alternately complete the clamping of the aluminum profile, avoid interference between the main clamping heads 32 and the auxiliary clamping heads 42, and ensure stable clamping of the aluminum profile.

[0044] Specifically, when positioning the aluminum profile, the aluminum profile is first delivered to the position through the feeding device 5, and the operating table 2 is driven by the longitudinal screw mechanism 12 to move the main clamp seat 23 to a coaxial position with the aluminum profile. Then the main clamp seat 23 moves toward the feeding device 5, and when the aluminum profile passes through the main clamp seat 23, the main clamp cylinder 31 clamps the aluminum profile, and then the main clamp seat 23 moves toward the auxiliary clamp seat 24, inserting the front end of the aluminum profile into the auxiliary clamp seat 24, and then the auxiliary clamp cylinder 41 slightly clamps the aluminum profile, and the main clamp cylinder 31 pushes the aluminum profile to continue to move toward the auxiliary clamp seat 24 until the positioning sensor is triggered, and then the main clamp seat 23 and the auxiliary clamp seat 24 alternately clamp the aluminum profile, so that the main clamp seat 23 and the auxiliary clamp seat 24 move to the clamping position in sequence.
