Description

TECHNICAL FIELD

[0001] The utility model relates to the field of aluminum alloy door and window production, and particularly relates to a screw corner assembling machine head for door and window corner assembling and a production line. BACKGROUND

[0002] With the continuous development of social economy, people's living standards are continuously improved, and the requirements for house doors and windows are also higher and higher. In addition to meeting the basic functional needs, the doors and windows also need to be energy-saving, beautiful, firm and reliable, so the requirements for aluminum alloy door and window assembly are also higher and higher.

[0003] Aluminum alloy door and window corner assembling refers to connecting four edges (i.e. four profiles) of a door and window at the end through a corner code, connecting two profiles at the corner of the door and window, and forming a window frame through the connection of four corners through a corner code. The installation process of the corner code is called corner assembling, and the corner assembling link plays a key role in the assembly efficiency and product quality of the aluminum alloy door and window. The existing corner assembling methods include riveting, pin connection and fastener connection, etc. Among them, the riveting method is to connect the profiles with the corner code, and then rivet the profiles and the corner code together through punch riveting, so as to finally form a finished window. The structure is as shown in Figure 1 , which is the most common processing method in the existing door and window production process, and has the advantages of simple processing and high efficiency.

[0004] Most of the existing corner assembling machines are mainly hydraulic corner assembling machines, which have the advantages of compact structure and large output. However, since the feeding speed of the corner assembling knife is adjusted by a hydraulic speed regulating valve, the synchronization is not good, which easily causes the misalignment of the profiles during corner assembling, affecting the quality of the finished window. Moreover, the adjustment of the position of the corner assembling knife needs to rely on the technical experience of the operator to ensure the accuracy, especially when the four-head corner assembling machine simultaneously assembles the four corners of the door and window, the synchronization of the four corners needs to be considered, and the positions of the eight corner assembling knives need to be correct. Each time different specifications of profiles are replaced, a considerable amount of time is needed to adjust the tool, which seriously affects the production efficiency and causes a large amount of waste of trial machine profiles. At the same time, there are defects such as leakage of the hydraulic station, which easily causes environmental pollution.

[0005] In addition, taking the fastener connection as an example, a connecting piece is arranged inside the two-piece profile to be connected, and the profile and the connecting piece are connected together by the fastener to complete the corner assembly. Since the connecting piece is inside the profile, the internal connecting piece cannot be seen in appearance. This process is simple and efficient, and the appearance of the obtained door and window is simple. Compared with the punching and riveting processing method, the fastener is more convenient to position, the production efficiency is improved, and the defects caused by the setting of the hydraulic station are avoided. However, in order to obtain door and window with strength meeting the demand, the fastener needs to be inserted into the upper and lower surfaces of the door and window respectively, so that the equipment needs to complete the automatic overturning of the door and window during processing. The existing public Chinese patent CN221088744U solves this problem. However, in actual production, it is found that the overturning of the door and window not only makes the processing process more complicated, but also often has a certain misalignment when the fastener is processed on the other surface after overturning, which requires repositioning to ensure accuracy after overturning, and cannot achieve ideal precise positioning and efficient corner assembly effect, and further improvement is needed.

The second servo motor drives the screw pair two to rotate through the synchronous belt mechanism, and the rotation of the screw pair two can drive the auxiliary V-shaped block to move up and down along the linear guide rail pair two fixed on the auxiliary V-shaped block fixing seat. The first air cylinder cooperates with the linear guide rail pair four to push out the auxiliary V-shaped block, so as to adapt to different auxiliary positioning positions of the door and window.

[0066] In addition, the upper side of the auxiliary V-shaped block is also provided with a pressing head 24-24, the top of the pressing head is connected with the telescopic rod of the second air cylinder 24-23, and the second air cylinder 24-23 is fixedly connected with the auxiliary V-shaped block fixing seat 24-12 through the air cylinder fixing seat 24-22. In the embodiment, the pressing head is mainly used for pressing the window frame or the window sash upper plane during corner assembly, so that the window frame upper plane is in the same plane, and the corner assembly effect is better and more beautiful. Since the pressing positions of the window frame and the window sash are different during corner assembly, the second air cylinder can be used to select the pressing position.

[0067] Specifically, the nail tightening mechanism is used for tightening the corner code and the profile of the door and window to complete the screw corner assembly, such as Figure 8As shown, the rivet mechanism 22 includes a rivet gun 22-1 and a moving mechanism for realizing linear motion of the rivet gun in three-dimensional directions, the moving mechanism including a rivet gun mounting plate 22-2 fixedly connected with the rivet gun, the rivet gun mounting plate being slidably connected with a support 22-4 through a Y-axis linear guide rail pair 22-10, one side of the rivet gun mounting plate being provided with a Y-axis servo motor 22-9, and an output shaft of the Y-axis servo motor being connected with the rivet gun mounting plate 22-2 through a Y-axis screw pair 22-8. Through driving of the Y-axis servo motor and cooperation of Y-axis screw pair transmission, the rivet gun mounting plate can be driven to move linearly along the Y-axis linear guide rail pair, so as to realize horizontal movement of the rivet gun in the Y-axis direction. The bottom of the support 22-4 is provided with an X-axis linear guide rail pair 22-7 connected with a mounting base, and the side surface of the support is fixedly connected with an X-axis screw pair 22-5 and an X-axis servo motor 22-6. Through driving of the X-axis servo motor and the X-axis screw pair, the support is driven to move linearly along the X-axis linear guide rail, so as to realize horizontal movement of the rivet gun in the X-axis direction. In addition, one side of the support 22-4 is vertically provided with a Z-axis linear guide rail pair 22-13, the support is slidably connected with a supporting plate 22-3 through the Z-axis linear guide rail pair, and the supporting plate 22-3 is fixedly connected with the rivet gun mounting plate through a Y-axis linear guide rail pair. The top of the support is provided with a vertically arranged Z-axis servo motor 22-12, and the output end of the Z-axis servo motor is connected with the supporting plate 22-3 through a Z-axis screw pair 22-11, so as to drive the supporting plate to ascend and descend along the Z-axis linear guide rail pair, and further realize height adjustment of the rivet gun.

[0068] Since the positions of screw groups of different profiles are different, the initial position of the rivet gun needs to be adjusted before the screw group of each profile and window type door window. In the embodiment, the specific adjustment method is as follows: the X-axis servo motor drives the X-axis screw pair to rotate, drives the support to move left and right, the Y-axis servo motor drives the Y-axis screw pair to rotate, drives the rivet gun mounting plate to move forward and backward, and the Z-axis servo motor drives the Z-axis screw pair to rotate, drives the supporting plate to move up and down, so as to finally realize high-precision position adjustment of the rivet gun with the support.
