Description

Technical Field

[0001] The invention relates to the technical field of door and window corner code processing equipment, and in particular to an airbag swing arm type adjustable corner extrusion machine. Background Art

[0002] Corner extrusion machines are widely used in the processing and assembly of aluminum alloy doors and windows. Through the processing of the corners of doors and windows, the reliability, stability and sealing of doors and windows are improved. Corner extrusion machines are mainly composed of prime movers, transmission mechanisms, actuators, and control systems. According to the number of corner extrusion knives in the actuator, they are divided into single-head corner assembly machines, double-head corner assembly machines, and four-head corner assembly machines.

[0003] The existing corner extrusion machines mainly have the following problems:

[0004] (1) Modern doors and windows have higher requirements for sealing, and the thickness of the panels varies. The existing cutters of the corner extrusion machine cannot be adjusted according to the different thicknesses of doors and windows, resulting in poor processing versatility for doors and windows of different sizes;

[0005] (2) The existing corner pressing machines are large in size, have poor coordination, and the pressing force is uneven during the pressing process, so it is difficult to ensure the pressing quality of the door and window corner codes.

[0006] Some angle extrusion machines with adjustable positions are disclosed in the prior art, but most of the prior art uses a motor + lead screw or hydraulic cylinder to drive the tool mounting frame to move during adjustment. Although this type of drive device has relatively high precision, it has a complex structure, resulting in relatively high costs and relatively short lifespan. Summary of the invention

[0007] The purpose of the present invention is to provide an airbag swing arm type adjustable corner squeezing machine, which has a compact structure, is easy to process, and can improve the function of squeezing corners of doors and windows of different thicknesses.

[0008] In order to achieve the above technical objectives, the present invention is implemented by the following technical solutions:

[0009] The present invention proposes an airbag rocker-arm type adjustable corner squeezing machine, comprising a base plate, on which a left corner squeezing knife driving mechanism and a right corner squeezing knife driving mechanism are symmetrically arranged, the left corner squeezing knife driving mechanism and the right corner squeezing knife driving mechanism are exactly the same, and each comprises an airbag, a rocker arm, a tool support frame, a motor, a gear, a rack, and a corner squeezing knife; the airbag is located below the base plate, the airbag is rotatably connected to the lower part of the rocker arm through a first pin shaft, the middle part of the rocker arm is rotatably connected to the base plate through a second pin shaft, and the top of the rocker arm is connected to the tool support frame through a third pin shaft, an open groove that can limit the third pin shaft from moving up and down is opened on the tool support frame, and the airbag realizes the left and right swing of the rocker arm by inflation and deflation; a tool support frame groove is opened on the base plate, and a slide rail is arranged in each tool support frame groove to realize the left and right movement of the tool support frame; and motors are installed up and down on the tool support frame, and each motor drives a corner squeezing knife to move up and down through a gear rack transmission structure; and a door and window fixing and adjusting device is also arranged on the base plate.

[0010] As a further technical solution, an airbag support plate is installed on the side of the airbag, and a connecting hole is provided on the airbag support plate;

[0011] As a further technical solution, a connecting ear is provided at the bottom of the bottom, and a connecting hole is provided on the connecting ear.

[0012] As a further technical solution, the bottom of the rocker arm is rotatably connected to the airbag support plate through a first pin, the middle of the rocker arm is connected to the connecting ear through a second pin, and the upper part of the rocker arm is connected to the tool support frame through a third pin.

[0013] As a further technical solution, an open slot is further provided on the side wall of the tool support frame, and both ends of the third pin shaft pass through the open slot to limit the up and down movement of the swing arm.

[0014] As a further technical solution, the door and window fixing and adjusting device includes two positioning strips, which are integrally formed with a space in the middle to avoid the sharp corners of the doors and windows. A threaded rod is arranged at the head thereof, which passes through the L-shaped plate and cooperates with a nut to fix it on the L-shaped plate, and the L-shaped plate is fixed to the base plate by bolts.

[0015] As a further technical solution, the door and window fixing and adjusting device further comprises two adjusting discs, which are eccentrically arranged with respect to the bottom plate and are used to adjust the angle between the two edges of the door and window.

[0016] As a further technical solution, the gear rack transmission structure includes a gear and a rack, the gear is connected to the motor, the gear drives the rack to move up and down, and the rack is connected to the angle extrusion knife.

[0017] As a further technical solution, slideways are provided on both sides of the rack.

[0018] As a further technical solution, a positioning strip is further provided on one side of the slideway, and the positioning strip cooperates with the long wedge-shaped block to squeeze the side surface of the corner extrusion knife.

[0019] In summary, the present invention has the following beneficial effects:

[0020] The present invention uses compressed air as the power, and the airbag pushes the rocker arm to move, thereby driving the tool support plate to move left and right along the slide rail; the gear is driven to move by the motor, and the gear is meshed with the rack in the slide rail, and one end of the rack is fixedly connected to the corner extrusion knife, thereby realizing the up and down movement of the corner extrusion knife. The up and down positions of the corner extrusion knife can be adjusted independently to adapt to the processing of doors and windows with different thicknesses and different angle code requirements. The device has a simple structure, relatively low cost, and relatively long service life.

[0021] Furthermore, since the control accuracy of the airbag itself is relatively low compared to that of servo motors, lead screws and other driving devices, in order to achieve processing accuracy, the present invention arranges the door and window fixing and adjusting device to be adjustable, that is, the position of the two positioning strips can be adjusted, and then in conjunction with the two adjustment disks, the position of the doors and windows can be fine-tuned, thereby achieving the same processing accuracy as that of servo motors, lead screws and other driving devices.

[0022] Furthermore, the present invention, through the design of the open groove on the tool support plate, makes the third pin shaft of the rocker arm only move up and down in the open groove, thereby ensuring the smooth left and right movement of the corner squeezing knife; in the gear rack structure, the rack is placed in the slideway, so that the movement of the corner squeezing knife is limited to the up and down directions, thereby achieving the purpose of improving processing accuracy, processing quality and high efficiency.

[0036] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0037] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0038] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise explicitly stated in the present invention, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or their combinations;

[0039] The present embodiment discloses an airbag swing lever type adjustable corner squeezing machine, wherein a left corner squeezing knife driving mechanism and a right corner squeezing knife driving mechanism are symmetrically arranged along the center line of the door and window fixing and adjusting device, and the left corner squeezing knife driving mechanism and the right corner squeezing knife driving mechanism are completely the same, and are symmetrically arranged on the bottom plate 1. The left corner squeezing knife driving mechanism in the figure is taken as an example to explain it; the left corner squeezing knife driving mechanism in the present embodiment includes an airbag 13, a swing lever 15, a slide rail 16, a tool support frame 6, a motor 7, a gear 8, a rack 11, a corner squeezing knife 10, a door and window fixing and adjusting device 12, a pressing plate 3, etc.;

[0040] The airbag 13 is located below the base plate 1, and inflation can realize the left and right swing of the swing rod 15; an airbag support plate 14 is arranged on the left side of the airbag 13, and a connecting hole is arranged on the airbag support plate 14, and the connecting hole of the airbag support plate 14 is rotatably connected to the swing rod 15 through a first pin shaft, and the middle part of the swing rod 15 is rotatably connected to the ear plate at the bottom of the base plate through a second pin shaft, and the upper part of the swing rod 15 passes through the through hole on the tool support frame 6, and the top of the swing rod 15 is connected to the tool support frame 6 through a third pin shaft, and an open groove 4 is also arranged on the side wall of the tool support frame 6, and the two ends of the third pin shaft pass through the open groove 4 to limit the up and down movement of the swing rod 15; when the airbag 13 is inflated, the upper part of the swing rod 15 swings to the right, thereby driving the tool support frame 6 to move to the right, and similarly, the right squeeze When the airbag of the corner knife driving mechanism is inflated, the upper part of the corresponding rocker arm 15 swings to the left, thereby driving the corresponding tool support frame to move to the left, realizing the opposite movement of the left and right corner knife driving mechanisms, and the distance between the two becomes smaller and smaller; when the airbag 13 is deflated, the upper part of the rocker arm 15 swings to the left, thereby driving the tool support frame 6 to move to the left. Similarly, when the airbag of the right corner knife driving mechanism is deflated, the upper part of the corresponding rocker arm swings to the right, thereby driving the corresponding tool support frame to move to the right, realizing the reverse movement of the left and right corner knife driving mechanisms, and the distance between the two becomes larger and larger; the present invention realizes the control of the tool support frame through the cooperation of the airbag and the rocker arm. Compared with the existing servo motor, lead screw, etc., this control method has low cost and good reliability, and is pollution-free and has a long service life compared with the hydraulic type.

[0041] Furthermore, in this embodiment, the base plate 1 is provided with front-to-back symmetrical tool support frame grooves, and each tool support frame groove is provided with a slide rail 16 to enable the corresponding tool support frame 6 to move left and right on the slide rail 16, and when the tool support frame 6 moves to the set position, its position can be fixed by the pressure plate 3.

[0042] Furthermore, a motor 7 is installed on the upper and lower left side surfaces of the right side plate of the tool support frame 6 of the left corner squeezing knife driving mechanism, and each motor 7 has an output shaft connected to a corresponding gear 8, and each gear 8 is meshed with a rack 11; a slideway is arranged on the right side surface of the right side plate of the tool support frame, and two racks 11 move up and down in the corresponding slideway; a corner squeezing knife 10 is fixed at one end of each rack 11, and the movement of the two pairs of gears and racks realizes the up and down movement of the two corner squeezing knives 10. Correspondingly, a motor 7 is installed on the upper and lower right side surfaces of the left side plate of the tool support frame 6 of the right corner squeezing knife driving mechanism, and the output shaft of each motor 7 is connected to a corresponding gear 8, and each gear 8 is meshed with a rack 11; a rack slide 9 is set on the left side surface of the left side plate of the tool support frame, and the two racks 11 move up and down in the corresponding rack slide; a corner squeezing knife 10 is fixed at one end of each rack 11, and the movement of the two pairs of gears and racks realizes the up and down movement of the two corner squeezing knives 10, and because the gear and the rack are meshed, a radial force will be applied to the rack, causing the rack to tilt to a certain extent. Therefore, a positioning block can be added on the back of the rack to overcome the tilt problem caused by the radial force, and the two sides of the positioning block are restricted in the rack slide 9.

[0043] Furthermore, a groove is provided in the center of the bottom plate 1, and the doors and windows are fixed by the door and window fixing and adjusting device 12, such as Figure 7 As shown, the door and window fixing and adjusting device 12 includes two positioning bars 121, which are integrally formed with a space in the middle to avoid the sharp corners of the door and window. A threaded rod 122 is set at the head thereof, and the threaded rod 122 passes through an L-shaped plate 123 and cooperates with a nut 124 to fix it on the L-shaped plate 123. The L-shaped plate is fixed to the base plate by bolts. The position of the two positioning bars 121 can be adjusted by rotating the nut 124, thereby adjusting the position of the door and window.

[0044] Furthermore, if Figure 1 , Figure 4 , Figure 6 As shown, the door and window fixing and adjusting device 12 also includes two adjustment discs 2, which are eccentrically mounted on the bottom plate 1. By rotating the adjustment discs 2, the two edges of the door and window can be fixed and a slight angle can be adjusted. Specifically, the two adjustment discs 2 are connected to the bottom plate through a rotating shaft, and the rotating shaft is located at a non-center position of the adjustment disc 2. When the two adjustment discs 2 are rotated toward the center of the bottom plate, the distance between the two adjustment discs 2 becomes smaller, and the door and window edges can be fixed. When the two adjustment discs 2 are rotated into place, the adjustment discs 2 can be fixed by other fixing parts such as bolts. Therefore, a fixing hole is also provided in the adjustment disc 2 to fix the position of the adjustment disc 2.

[0045] It should be further explained that the position of the L-shaped plate can be adjusted by rotating the nut 124. When the position adjustment of the corner extrusion knife by the airbag and the motor cannot meet the accuracy requirements, the position of the door and window can be fine-tuned by adjusting the position of the positioning bar 121 and the positions of the two adjustment discs 2, and then the corner extrusion process can be performed.

[0046] Furthermore, in this embodiment, the airbags of the left corner squeezing knife driving mechanism and the right corner squeezing knife driving mechanism are bilaterally symmetrical, and each airbag is connected to the swing rod 15 through an airbag support plate 14, and the purpose of the airbag driving the swing rod 15 to move is achieved by filling the airbag with gas of a certain pressure;

[0047] Furthermore, the structure of the swing rod 15 is as follows: Figure 8 As shown, the bottom, middle and upper parts of the swing rod 15 are all opened with holes, the middle part of the swing rod is opened with a hole and is directly connected to the ear plate on the bottom plate through the second pin shaft, the upper part of the swing rod 15 is provided with a third pin shaft, and the two ends of the third pin shaft are located in the open groove, and the swing rod 15 transmits the power of the airbag to the tool support frame through the third pin shaft, so that the tool support frame moves left and right along the slide rail;

[0048] Furthermore, if Fig.10 As shown, the tool support frame 6 of the left corner extrusion knife driving mechanism includes a bottom plate 61, a front side plate 62, a rear side plate 63 and a right side plate 64; a long strip through hole 65 is opened on the bottom plate, and the hole is for the rocker arm 5 to pass through and limit the left and right movement of the rocker arm 5; an open groove 4 is set on the front side plate and the rear side plate, and the open groove 4 is for the third pin shaft to pass through; two through holes 66, a rack slide 9 and a positioning strip 67 are set on the right side plate, and these two through holes 66 are used for the motor drive shaft to pass through, and the rack is installed in the rack slide 9, and the rack slide 9 limits the rack so that it can only move up and down; the positioning strip 67 cooperates with the long strip wedge block (not shown in the figure). When the corner extrusion knife is adjusted to the specified position, the wedge block is inserted to squeeze the corner extrusion knife and the guide block to prevent the force change of the corner extrusion knife position during work.

[0049] Similarly, the tool support frame 6 of the right corner extrusion knife driving mechanism includes a bottom plate, a front side plate, a rear side plate and a left side plate; a long strip through hole is opened on the bottom plate, and the hole is for the rocker arm to pass through and limit the left and right movement of the rocker arm; open grooves are set on the front side plate and the rear side plate, and the open grooves are for the third pin shaft to pass through; two through holes, a rack slide and a positioning strip are set on the left side plate, and these two through holes are for the motor drive shaft to pass through, and the positioning strip cooperates with the long strip of wedge block (not shown in the figure). When the corner extrusion knife is adjusted to the specified position, the wedge block is inserted to squeeze the corner extrusion knife and the guide block to prevent the force change of the corner extrusion knife position during operation.

[0050] The present invention uses compressed air as the power, and the airbag pushes the rocker arm to move left and right, thereby driving the tool support plate to move left and right along the slide rail, thereby realizing the left and right movement of the corner extrusion knife 10; the motor drives the gear to move, the gear engages with the rack in the slide rail, and one end of the rack is fixedly connected to the corner extrusion knife, thereby realizing the up and down movement of the corner extrusion knife, and realizing that the up and down position of the corner extrusion knife can be adjusted to adapt to the processing of doors and windows with different thicknesses and different angle code requirements.

[0051] Furthermore, since the control accuracy of the airbag itself is relatively low compared to that of servo motors, lead screws and other driving devices, in order to achieve processing accuracy, the present invention arranges the door and window fixing and adjusting device to be adjustable, that is, the position of the two positioning strips can be adjusted, and then in conjunction with the two adjustment disks, the position of the doors and windows can be fine-tuned, thereby achieving the same processing accuracy as that of servo motors, lead screws and other driving devices.

[0052] The present invention enables the cylindrical hole-opening pin to move up and down only in the open groove through the design of the open groove on the tool support plate, thereby ensuring that the left and right movement of the corner-extruding knife is smooth; in the gear rack structure, the rack is placed in the slideway, so that the movement of the corner-extruding knife is limited to the up and down directions, thereby achieving the purpose of improving processing accuracy, processing quality and high efficiency.

[0053] The corner extrusion machine can realize the processing of corner doors and windows of different thicknesses and sizes. It has the characteristics of high processing precision, good quality, small machine footprint, simple structure and easy operation. It can be widely used in the production and manufacturing of various types of corner doors and windows.

[0054] Finally, it should be noted that relational terms such as first and second are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
