Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of aluminum alloy door and window processing technology, and more specifically to a metal door and window opening processing device. Background Technology
[0002] Aluminum alloy doors and windows are made of aluminum alloy extruded profiles as frames, mullions and sashes. The processing of aluminum alloy doors and windows is a relatively complex process. Various processing equipment is used to cut, drill and mill aluminum alloy profiles to process them into various shapes, and finally they are assembled together to form framed metal doors and windows.
[0003] When processing aluminum alloy doors and windows, measurements need to be taken in advance. Then, the positions of the beveled angles to be cut are drawn on the aluminum alloy profile. The aluminum alloy profile is then cut to the required length using a cutting machine. Finally, the two beveled angles are spliced together to form the door and window openings.
[0004] However, in practice, it has been noted that since the two aluminum alloy profiles are cut separately, the accuracy of the two bevels cannot be guaranteed during the cutting process. Therefore, during assembly, errors can lead to a large gap between the two bevels, resulting in poor assembly accuracy. Utility Model Content
[0005] The purpose of this invention is to provide a metal door and window opening processing device. Through a rectangular array of interlocking grippers, two overlapping aluminum alloy profiles can be cut simultaneously, ensuring that the corners of the installed opening are at right angles, thus improving the processing accuracy of aluminum alloy door and window openings.

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-7 This utility model provides a metal door and window opening processing device, including a support base 1, a rotatable positioning seat 4 movably connected to the top of the support base 1, and a cutting machine 3 provided above the rotatable positioning seat 4. A support shaft plate 2 is fixedly connected to the end of the support base 1, and the support shaft plate 2 and the end of the cutting machine 3 are movably connected.
[0031] A limiting panel 5 is fixedly connected to the rotatable positioning seat 4, and staggered grippers 6 are movably connected in a circular array in the limiting panel 5. A clamping device 7 is installed on the side of the rotatable positioning seat 4, and a fixing cover plate 8 is fixedly connected above the clamping device 7.
[0032] In this embodiment, the rotatable positioning seat 4 has a hollow seat 41, and the bottom of the hollow seat 41 is integrally provided with a support column, and the end of the support column is interference-fitted with a fixed bearing, and the outer ring of the fixed bearing is embedded in the support base 1.
[0033] Furthermore, a limiting groove 42 is provided on the inner side of the hollow seat 41, and a central positioning post 43 is integrally fixedly connected to the center position of the hollow seat 41, and the bottom of the central positioning post 43 is located at the center position of the limiting groove 42.
[0034] Furthermore, the limiting panel 5 includes a support plate 51 fixedly connected above the hollow base 41, and the support plate 51 has a cross groove 52 corresponding to the limiting groove 42, and the end of the central positioning post 43 is inserted into the center of the cross groove 52.
[0035] More specifically, the support plate 51 is also provided with a cutting slit 53 spaced apart from the cross groove 52, and the cutting slit 53 is arranged in a cross shape. The ends of the interlaced claws 6 extend through the cross groove 52 to the top of the support plate 51.
[0036] By adopting the above technical solution, the cross groove 52 in the limiting panel 5 and the limiting groove 42 opened on the inner side of the hollow seat 41 cooperate with each other to limit the interlocking claws 6 arranged in a ring array, so as to ensure that the interlocking claws 6 move in a specific direction, thereby simultaneously cutting two interlocking aluminum alloy profiles and improving the window accuracy after installation.
[0037] Furthermore, the interlaced gripper 6 has an extension pin 62 that is inserted into the cross slide groove 52, and the extension pin 62 slides in conjunction with the cross slide groove 52, and a cutting slit 63 is also provided in the extension pin 62.
[0038] The side of the extension post 62 is fitted with a return spring 64, and the other end of the return spring 64 is fixedly connected to the side of the center positioning post 43.
[0039] Furthermore, the bottom of the extended locking post 62 is integrally provided with a limiting slide plate 61, and a sliding concave wheel 65 is movably connected below the limiting slide plate 61. The limiting slide plate 61 and the sliding concave wheel 65 are respectively located between the hollow seat 41 and the support plate 51.
[0040] By adopting the above technical solution, two interlocking aluminum alloy profiles are simultaneously positioned by the rectangular array of interlocking grippers 6, and each interlocking gripper 6 is provided with a reset spring 64 on its side. The elasticity of the reset spring 64 pushes the interlocking grippers 6 to automatically reset.
[0041] Furthermore, the bottom of the limiting slide plate 61 is integrally provided with an insert rod, and the sliding concave wheel 65 is movably connected to the insert rod through a bearing, and the end of the insert rod away from the limiting slide plate 61 is inserted into the inner side of the limiting slide groove 42.
[0042] Furthermore, the clamp 7 has a storage box 71 fixedly connected to the side of the hollow seat 41, and a winding roller 72 is movably connected in the storage box 71. A rotating wheel 73 is fixedly connected above the winding roller 72. A traction rope 75 is wound in the rotating wheel 73, and the traction rope 75 passes around the sliding concave wheel 65 at the bottom of each of the limiting slide plates 61.
[0043] By adopting the above technical solution, the winding roller 72 is rotated by the rotating wheel 73, and the traction rope 75 is wound onto the winding roller 72, so that the length of the traction rope 75 is reduced, thereby driving the clamp 7 to slide along the cross groove 52 in the limiting panel 5 to cut the intersecting aluminum alloy profiles, ensuring that the cut parts of the two aluminum alloy profiles fit tightly together, thereby improving the opening accuracy during door and window assembly.
[0044] Furthermore, the storage box 71 is threadedly connected to a locking knob 74 on its side, and the end of the locking knob 74 passes through the storage box 71 and fits against the side of the winding roller 72. Tightening the locking knob 74 will make the end of the locking knob 74 fit against the winding roller 72, thereby locking the winding roller 72 and preventing the winding roller 72 from rotating on its own.
[0045] Furthermore, the fixed cover plate 8 is fixedly connected above the storage box 71, and the rotating wheel 73 is located above the fixed cover plate 8. The end of the rotating wheel 73 passes through the fixed cover plate 8 and is connected to the winding roller 72. The rotating wheel 73 rotates the winding roller 72, thereby winding the traction rope 75. The contraction of the traction rope 75 drives the interlaced grippers 6.
[0046] Furthermore, the hollow base 41 has a groove on the side near the storage box 71, and guide wheels 44 are symmetrically provided on the side of the groove. The guide wheels 44 are movably connected to the inner side of the hollow base 41, and both ends of the traction rope 75 pass around the side of the guide wheel 44 and then pass through the groove into the storage box 71.
[0047] When the winding roller 72 rotates, it will retract the traction rope 75, causing the inner side of the traction rope 75 to contract. After being guided by the guide wheel 44, the traction rope 7 drives the interlaced grippers 6 to move simultaneously, thereby clamping the aluminum alloy profile.
[0048] The working principle of this utility model is as follows: First, two aluminum alloy sections to be cut are interlaced and stacked together. The stacked aluminum alloy profile is then placed above the support plate 51. Then, the rotating wheel 73 rotates the winding roller 72. The traction rope 75, guided by the guide wheel 44, winds onto the winding roller 72, causing the portion of the traction rope 75 located in the hollow seat 41 to contract. This, in turn, causes the sliding concave wheel 65 to drive the limiting slide plate 61 to move. Extending pins 62, arranged in a rectangular array, clamp the two interlaced aluminum alloy profiles at their corners. Then, the cutting machine 3 cuts at the connection point of the two aluminum alloy profiles, ensuring that the angle between the cut sections is a right angle, thus improving cutting accuracy. This ensures that the corner positions of the installed door and window openings are set at right angles, thereby improving the processing accuracy of the door and window openings. The structure is simple, the operation is very convenient, and it effectively reduces manual labor intensity.
