Description

Technical Field

[0001] This utility model relates to the field of corner assembly machine technology, specifically to a diagonal mechanism for a door and window corner assembly machine. Background Technology

[0002] Corner assembly machines are specialized equipment for producing high-end thermally broken aluminum alloy doors and windows, suitable for 90-degree angle connections in corner-type aluminum doors and windows. In some regions, they are also called corner extrusion machines, corner impact machines, or edge corner machines. Depending on the type of corners they can assemble, they are classified as single-head, double-head, and four-head corner assembly machines.

[0003] The existing publicly available technology, application number CN202123057180.1, describes a diagonal adjustment mechanism for a corner assembly machine. By manually rotating a rotating wheel, a rotating rod can drive a first bevel gear to rotate on the worktable. The first bevel gear drives a second bevel gear to rotate, which in turn drives a threaded rod to rotate. This allows an internal threaded cylinder to rise or fall at the top of the threaded rod. Consequently, a movable seat can move up and down in a limiting groove on a fixed frame via a limiting block. This allows the push plate on the servo electric cylinder to be adjusted up and down in height, enabling diagonal processing of aluminum doors and windows of different thicknesses.

[0004] However, the aforementioned patent still has certain drawbacks in its use: although it can adapt to the diagonal processing of aluminum doors and windows of different thicknesses, when performing diagonal operations on aluminum doors and windows, it is necessary for personnel to manually press and fix both sides of the aluminum doors and windows to ensure diagonal stability and prevent misalignment and separation. However, prolonged manual pressing not only increases the labor intensity of personnel, but also weakens the pressing force as the number of operations increases, thus affecting the diagonal effect of the aluminum doors and windows. Furthermore, the pressing force exerts a reverse resistance on the aluminum doors and windows when the push plate is pushed out, causing the aluminum doors and windows to tend to rotate along the pressing position, which is not conducive to diagonal operations on aluminum doors and windows. The overall use effect is not ideal.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a diagonal mechanism for door and window corner assembly machines, which has the following beneficial effects:

[0020] This invention utilizes clamping plates and a lower pressure plate.

A third cylinder 22 is installed in the middle of the top of the fixing plate 21. A lower pressure plate 23 is slidably connected below the fixing plate 21 between the guide rods 18. One end of the third cylinder 22 passes through one side of the fixing plate 21 and is connected to the lower pressure plate 23. A bidirectional screw 19 is installed on one side inside the lower pressure plate 23. Clamping plates 20 are symmetrically sleeved on the outer periphery of both ends of the bidirectional screw 19. The limiting mechanism 6 is set to fix and limit the door and window edges during corner assembly, thereby improving the stability of the door and window edges, improving the quality of corner assembly, and facilitating better use.

[0032] In one embodiment, a first cylinder 3 is installed at the bottom of the drive groove 2, and one end of the first cylinder 3 is connected to the bottom of one side surface of the connecting block 4.

[0033] In one embodiment, an adjusting rod 8 is installed inside the adjusting groove 7, and a movable frame 12 is slidably connected to the outer periphery of the adjusting rod 8. A second cylinder 11 is installed at one end of the movable frame 12, and a corner cutter 10 is connected to one end of the second cylinder 11. Cylinders are common structures with diverse types and mature application technologies, so they will not be described in detail.

[0034] In one embodiment, rubber pads are provided on the surface of the pressure plate 23 and the surface of the clamping plate 20. The rubber pads are provided to reduce the pressure damage to the doors and windows, while increasing friction and improving stability.

[0035] In one embodiment, through holes are symmetrically provided at the middle position of both sides of the lower pressure plate 23. The through holes are provided to facilitate the movement of the lower pressure plate 23 along the guide rod 18.

[0036] In one embodiment, both the connecting block 4 and the movable frame 12 are L-shaped structures. The L-shaped structure is designed to facilitate the movement of the connecting block 4 and the movable frame 12 and the installation of the structures on the connecting block 4 and the movable frame 12, thereby facilitating the pushing and using of both sides of the door and window to achieve the purpose of corner assembly.

[0037] In one embodiment, positioning holes 13 are provided on the surface of the movable frame 12 and the surface of the adjusting rod 8, and bolts are provided between the positioning holes 13.

[0038] Working Principle: In actual use, personnel can pass one end of the door / window through the guide rods 18, connecting the two sets of door / window structures with the corner brackets. The connected door / window is then placed between the abutment plate 9 and the pushing block 5. The operation of the first cylinder 3 and the second cylinder 11 drives the pushing block 5 to abut the door / window against the abutment plate 9. The corner bracketing operation is then performed using the corner bracketing knife 10. After the door / window is placed between the guide rods 18, the push of the third cylinder 22 causes the lower pressure plate 23 to move downwards along the guide rods 18, abutting against the surface of the door / window. Rotating the bidirectional screw 19 causes the clamping plates 20 to move in opposite directions, clamping and fixing the sides of the door / window. This ensures the door / window remains secure. The device ensures stability during corner assembly, preventing misalignment of doors and windows due to vibration or other factors, thus avoiding gaps or offsets. It also replaces manual pressing, effectively reducing labor intensity and improving overall device performance. When the corner assembly knife 10 pushes the door or window, the moving seat 14 also moves. Since the door and window are clamped and fixed, they move synchronously, effectively preventing large deviations and ensuring corner assembly quality for better device use. After corner assembly, the return of the third cylinder 22 creates a gap between the lower pressure plate 23 and the moving seat 14, allowing personnel to tilt and remove the corner of the door or window for subsequent operations. The device offers advantages such as labor-saving operation, assisted positioning, and high processing quality.
