Description

Technical Field

[0001] The present invention relates to the technical field of door and window assembly positioning, and particularly to a rapid assembly positioning device for aluminum alloy doors and windows. Background Art

[0002] Aluminum alloy doors and windows are commonly used closed structures in building installations. With the requirements of building shapes and lighting, more and more buildings use curved aluminum alloy door and window structures. The curved aluminum alloy door and window structures have better lighting effects and are more beautiful. The curved aluminum alloy doors and windows are composed of door and window frames and glass window sashes, and the door and window frames are an important part of them. Compared with traditional flat door and window frames, the assembly requirements of the door and window frames of curved aluminum alloy doors and windows are higher, and the assembly process is more complex. The common curved door and window frames are assembled by two upper and lower curved window frame profiles and two left and right straight window frame profiles. The ends of the curved window frame profiles are spliced with the ends of the straight window frame profiles through corner codes and fixed with dowel pins.

[0003] As Figure 1 shown, when assembling the door and window frames of curved aluminum alloy doors and windows, it is usually necessary to use symmetric support frames 1 to support the curved window frame profiles 4. After the worker places the corner codes at the ends of the curved window frame profiles 4, the straight window frame profiles 7 are spliced, and after the overall door and window frame splicing is completed, positioning clamps 10 are used to clamp and position the four splicing joints of the curved window frame profiles and the straight window frame profiles. Subsequently, dowel pins and sealant are driven in with tools, and thus the assembly of the overall door and window frame can be completed.

[0004] However, in the process of assembling the curved door and window frames as described above, the symmetric support frames 1 can only play a supporting role, and it is difficult for them to position the placed curved window frame profiles 4. In addition, the disassembly and assembly of the positioning clamps 10 at the four splicing joints of the curved window frame profiles 4 and the straight window frame profiles 7 are rather inconvenient, and at the same time, multiple workers are required to cooperate in positioning the window frame profiles, that is, it is difficult to achieve the rapid assembly and positioning of the curved door and window frames. Therefore, a rapid assembly positioning device for aluminum alloy doors and windows that can position the curved door and window frames to assist rapid assembly is needed. Summary of the Invention

[0005] The purpose of the present invention is to solve the defect in the prior art that multiple workers are required to cooperate in positioning the window frame profiles, and it is difficult to achieve the rapid assembly and positioning of the curved door and window frames, and to propose a rapid assembly positioning device for aluminum alloy doors and windows.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions: A rapid assembly and positioning device for aluminum alloy doors and windows, comprising symmetric support frames. Front chutes and rear chutes are respectively provided on the outer sides of the symmetric support frames. A clamping and positioning mechanism A and a clamping and positioning mechanism B for clamping and positioning the arc-shaped window frame profiles are respectively arranged inside the front chute and the rear chute. A support and positioning mechanism for supporting and positioning the straight-shaped window frame profiles is jointly arranged between the clamping and positioning mechanism A and the clamping and positioning mechanism B on the same side. The clamping and positioning mechanism A and the clamping and positioning mechanism B respectively comprise clamping members A and B with the same structure. An abutting and positioning member is arranged outside the clamping member A, and a pressing and positioning member is arranged outside the clamping member B. The support and positioning mechanism comprises support members A and B with the same structure. The support member A moves synchronously with the clamping member A, and a return spring is arranged between the clamping member A and the front chute. A U-shaped elastic front and rear telescopic rod is arranged between the support member B and the clamping member B. An adjusting electro-hydraulic push rod and a side pressing and positioning member are arranged between the support member A and the support member B.

[0007] The above technical solution further includes: Both the clamping member A and the clamping member B include a front baffle, a rear block, and a middle roller rotatably connected between the two. An L-shaped connecting plate is fixedly connected to the outside of the rear block. A clamping electro-hydraulic push rod is installed inside the L-shaped connecting plate. The output end of the clamping electro-hydraulic push rod is fixedly connected to a clamping plate slidably connected inside the L-shaped connecting plate; By starting the clamping electro-hydraulic push rod to extend, the clamping plate can cooperate with the front baffle to clamp the arc-shaped window frame profile.

[0008] The abutting and positioning member includes a chute opening communicating with the front chute, a trapezoidal linkage block sliding vertically inside the front chute, a through opening formed at the bottom of the L-shaped connecting plate, and a trapezoidal abutting block A fixedly connected to the bottom of the clamping plate. Both the through opening and the trapezoidal abutting block A are located outside the clamping member A. A trapezoidal positioning block is slidably connected inside the chute opening. A connecting spring is fixedly connected between the trapezoidal positioning block and the chute opening. A U-shaped connecting rod is fixedly connected between the trapezoidal positioning block and the trapezoidal linkage block; When the front baffle moves forward to abut against the inner wall of the front chute, the trapezoidal positioning block will abut against the outside of the rear block for abutting and positioning; When the trapezoidal abutting block A slides towards the direction close to the return spring, it can abut against the trapezoidal linkage block and the trapezoidal positioning block to move downward; when the clamping electro-hydraulic push rod is started to shorten to release the clamping action of the clamping member A, the clamping plate can drive the trapezoidal abutting block A to move to release the abutting and positioning action of the abutting and positioning member on the clamping member A.

[0009] The downward pressing and positioning member includes a horizontal damping plate fixedly connected below the rear chute, a U-shaped elastic up-and-down telescopic plate fixedly connected to the outside of the L-shaped connecting plate, and a trapezoidal abutting block B fixedly connected to the bottom of the clamping plate. The U-shaped elastic up-and-down telescopic plate and the trapezoidal abutting block B are both located outside the clamping member B. One end of the U-shaped elastic up-and-down telescopic plate away from the L-shaped connecting plate is fixedly connected with a trapezoidal downward pressing block and a downward pressing positioning gasket that are fixedly connected to each other. When the trapezoidal abutting block B slides in the direction away from the U-shaped elastic front-and-back telescopic rod, it can abut against the trapezoidal downward pressing block and the downward pressing positioning gasket to move downward. When the clamping electro-hydraulic push rod is started to extend to clamp the arc-shaped window frame profile, the clamping plate can drive the trapezoidal abutting block B, so that the downward pressing positioning gasket presses the horizontal damping plate downward to realize the downward pressing and positioning of the clamping member B.

[0010] Both the support member A and the support member B include a limit seat, a vertical limit plate slidably connected inside the limit seat, and a limit spring fixedly connected between the two. The limit seat of the support member A is slidably arranged inside the front chute and fixedly connected to the clamping member A. The limit seat of the support member B is slidably arranged inside the rear chute and slidably connected to the clamping member B. The clamping member A and the support member A can always move synchronously, and the clamping member B and the support member B can move synchronously or asynchronously.

[0011] A connecting sleeve slides vertically outside the vertical limit plate. A support spring is arranged between the connecting sleeve and the vertical limit plate. The top of the connecting sleeve is fixedly connected with a limit block. The inner side surface of the limit block coincides with the inner side surface of the vertical limit plate. A support roller is rotatably connected to the inner side of the limit block. After the arc-shaped window frame profile is placed on the middle rollers on both sides, both sides of the arc-shaped window frame profile will respectively abut against the vertical limit plates on both sides to drive the inner side surface of the limit block to coincide with the outer assembly surface between the arc-shaped window frame profile and the straight-shaped window frame profile.

[0012] The side pressing and positioning member includes a vertical damping plate embedded in the side surface of the vertical limit plate and a sealing block fixedly connected inside the connecting sleeve. An airtight cavity and a communicating cavity are opened inside the sealing block. A piston connecting rod is arranged inside the airtight cavity. The piston connecting rod extends into the communicating cavity and is fixedly connected with a side pressing positioning gasket. When the piston connecting rod slides in the direction close to the vertical limit plate, it can drive the side pressing positioning gasket to move outwards. When the airtight cavity is inflated, the piston connecting rod can drive the side pressing positioning gasket to move outwards, so that the side pressing positioning gasket presses the vertical damping plate outwards to realize the side pressing and positioning of the support member A and the support member B.

[0013] The side pressure positioning member further includes a mounting sleeve fixedly connected to the outside of the front chute and a rectangular extrusion block fixedly connected to the outside of the limit seat. The rectangular extrusion block is located outside the support member A. An elastic airbag is arranged inside the mounting sleeve. The top of the elastic airbag is fixedly communicated with a connecting hose A. One end of the connecting hose A away from the elastic airbag is fixedly communicated with a connecting hose B. Both ends of the connecting hose B extend into the airtight cavities on both sides; When the front-pushing straight window frame profile and the arc window frame profile are assembled for positioning the clamping member A, the rectangular extrusion block can extrude the elastic airbag to inflate the inside of the airtight cavity.

[0014] The present invention has the following beneficial effects: 1. In the present invention, by first placing two arc window frame profiles and then placing two straight window frame profiles, the outer assembly surfaces of the arc window frame profiles can be automatically aligned with the outer assembly surfaces of the straight window frame profiles placed on the support rollers, eliminating the step of manually aligning the outer assembly surfaces between the arc window frame profiles and the straight window frame profiles, thereby accelerating the assembly between the arc window frame profiles and the straight window frame profiles.

[0015] 2. In the present invention, by synchronously pushing two straight window frame profiles forward, their ends can be closely attached to the assembly surfaces of the arc window frame profile. At the same time, the abutting positioning member abuts and positions the clamping member A to prevent the front arc window frame profile from moving backward, and the side pressure positioning member laterally presses and positions the support member A and the support member B to maintain the horizontal support height of the straight window frame profile. That is, synchronously pushing two straight window frame profiles forward can complete the assembly positioning between the front arc window frame profile and the two straight window frame profiles on both sides.

[0016] 3. In the present invention, by synchronously pushing two straight window frame profiles forward, their ends can be closely attached to the assembly surfaces of the two straight window frame profiles on both sides. Subsequently, when the clamping electro-hydraulic push rod is started to clamp and position the rear arc window frame profile, the downward pressure positioning member can downwardly press and position the clamping member B, thereby realizing the assembly positioning of the overall window frame profile.

[0017] 4. In the present invention, by starting the clamping electro-hydraulic push rods on both sides to shorten to release the clamping action of the clamping member A and the clamping member B on the arc window frame profile, the abutting positioning action of the abutting positioning member on the clamping member A, the constant support action of the support member A and the support member B, and the downward pressure positioning action of the downward pressure positioning member on the clamping member B can be released, thereby realizing the rapid removal of the arc door and window frame.

[0018] In summary, the present invention does not require multiple workers to cooperate for positioning and clamping at the four corners. By placing the window frame profiles in the corresponding positions, the clamping member A clamps the front arc window frame profile, two workers synchronously push two straight window frame profiles and the rear arc window frame profile forward, and the clamping member B clamps the rear arc window frame profile, the rapid assembly and positioning work of the arc door and window frame can be completed.

Detailed implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Such as Figures 2 to 12As shown in the figure, a rapid assembly and positioning device for aluminum alloy doors and windows proposed by the present invention includes symmetric support frames 1. Front chutes 2 and rear chutes 3 are respectively provided on the outside of the symmetric support frames 1. Clamping and positioning mechanisms A 500 and clamping and positioning mechanisms B 600 for clamping and positioning the arc-shaped window frame profiles 4 are respectively arranged inside the front chutes 2 and rear chutes 3. The clamping and positioning mechanisms A 500 and clamping and positioning mechanisms B 600 respectively include clamping members A 510 and clamping members B 610 with the same structure. The clamping member A 510 and the clamping member B 610 both include a front baffle 561, a rear baffle 562, and a middle roller 563 rotatably connected between the two. An L-shaped connecting plate 564 is fixedly connected to the outside of the rear baffle 562. A clamping electro-hydraulic push rod 565 is installed inside the L-shaped connecting plate 564. The output end of the clamping electro-hydraulic push rod 565 is fixedly connected to a clamping plate 566 slidably connected inside the L-shaped connecting plate 564. After the arc-shaped window frame profile 4 is placed on the middle rollers 563 on both sides, due to the symmetry of the arc-shaped window frame profile 4, it is always symmetric about the midline of the symmetric support frame 1. By starting the clamping electro-hydraulic push rod 565 to extend, the clamping plate 566 can cooperate with the front baffle 561 to clamp the arc-shaped window frame profile 4.

[0023] A butt-joint positioning member 520 is arranged outside the clamping member A 510. The butt-joint positioning member 520 includes a chute opening 521 communicated with the front chute 2, a trapezoidal linkage block 522 vertically sliding inside the front chute 2, a through port 523 opened at the bottom of the L-shaped connecting plate 564, and a trapezoidal butt-joint block A 524 fixedly connected to the bottom of the clamping plate 566. The through port 523 and the trapezoidal butt-joint block A 524 are both located outside the clamping member A 510. A trapezoidal positioning block 525 is slidably connected inside the chute opening 521. A connecting spring 526 is fixedly connected between the trapezoidal positioning block 525 and the chute opening 521. A U-shaped connecting rod 527 is fixedly connected between the trapezoidal positioning block 525 and the trapezoidal linkage block 522. A return spring 530 is arranged between the clamping member A 510 and the front chute 2. When the return spring 530 is in its original length state, the trapezoidal positioning block 525 is abutted inside the chute opening 521, and the trapezoidal linkage block 522 does not block the passage of the trapezoidal butt-joint block A 524. When the front baffle 561 moves forward to abut against the inner wall of the front chute 2, the trapezoidal positioning block 525 will abut against the outside of the rear baffle 562 for butt-joint positioning to prevent the clamping member A 510 from moving backward. When the clamping electro-hydraulic push rod 565 is started to shorten to release the clamping action of the clamping member A 510 on the arc-shaped window frame profile 4, the clamping plate 566 can drive the trapezoidal butt-joint block A 524 to move. The trapezoidal butt-joint block A 524 sliding in the direction close to the return spring 530 can abut against the trapezoidal linkage block 522 and the trapezoidal positioning block 525 to move downward to release the butt-joint positioning action of the butt-joint positioning member 520 on the clamping member A510.

[0024] An external pressing and positioning member 620 is provided outside the clamping member B 610. The pressing and positioning member 620 includes a horizontal damping plate 621 fixedly connected below the rear sliding groove 3, a U-shaped elastic up-and-down telescopic plate 622 fixedly connected to the outside of the L-shaped connecting plate 564, and a trapezoidal abutting block B 623 fixedly connected to the bottom of the clamping plate 566. Both the U-shaped elastic up-and-down telescopic plate 622 and the trapezoidal abutting block B 623 are located outside the clamping member B 610. One end of the U-shaped elastic up-and-down telescopic plate 622 away from the L-shaped connecting plate 564 is fixedly connected with a trapezoidal pressing block 624 and a pressing and positioning gasket 625 which are fixedly connected to each other. When the clamping electro-hydraulic push rod 565 is started to extend to clamp the arc-shaped window frame profile 4, the clamping plate 566 can drive the trapezoidal abutting block B 623 to move. When the trapezoidal abutting block B 623 slides in a direction away from the U-shaped elastic front-and-back telescopic rod 830, it can abut against the trapezoidal pressing block 624 and the pressing and positioning gasket 625 to move downward, so that the pressing and positioning gasket 625 presses the horizontal damping plate 621 downward to realize the downward pressing and positioning of the clamping member B 610.

[0025] A support and positioning mechanism 800 for supporting and positioning the straight window frame profile 7 is jointly provided between the clamping and positioning mechanism A 500 and the clamping and positioning mechanism B 600 on the same side. The support and positioning mechanism 800 includes a support member A 810 and a support member B 820 with the same structure. The support member A 810 moves synchronously with the clamping member A 510. A U-shaped elastic front-and-back telescopic rod 830 is provided between the support member B 820 and the clamping member B 610. An adjusting electro-hydraulic push rod 840 and a side pressing and positioning member 850 are provided between the support member A 810 and the support member B 820.

[0026] Both the support member A 810 and the support member B 820 include a limit seat 121, a vertical limit plate 122 slidably connected inside the limit seat 121, and a limit spring 123 fixedly connected between the two. The limit seat 121 included in the support member A 810 is slidably arranged inside the front chute 2 and fixedly connected to the clamping member A 510. The limit seat 121 included in the support member B 820 is slidably arranged inside the rear chute 3 and slidably connected to the clamping member B 610. That is, the clamping member A 510 and the support member A 810 can always move synchronously. The clamping member B 610 and the support member B 820 can move synchronously or asynchronously. A connecting sleeve 124 is slidably arranged vertically outside the vertical limit plate 122. A support spring 125 is arranged between the connecting sleeve 124 and the vertical limit plate 122. The top of the connecting sleeve 124 is fixedly connected with a limit block 126. The inner side surface of the limit block 126 coincides with the inner side surface of the vertical limit plate 122. A support roller 127 is rotatably connected to the inner side of the limit block 126. That is, after the arc-shaped window frame profile 4 is placed on the middle rollers 563 on both sides, the two sides of the arc-shaped window frame profile 4 will respectively abut against the vertical limit plates 122 on both sides, so that the vertical limit plates 122 drive the inner side surface of the limit block 126 to coincide with the outer assembly surface between the arc-shaped window frame profile 4 and the straight window frame profile 7.

[0027] The side pressure positioning member 850 includes a vertical damping plate 851 embedded in the side surface of the vertical limit plate 122 and a sealing block 852 fixedly connected inside the connecting sleeve 124. An airtight cavity 853 and a communication cavity 854 communicating with each other are formed inside the sealing block 852. A piston connecting rod 855 is arranged inside the airtight cavity 853. The piston connecting rod 855 extends into the communication cavity 854 and is fixedly connected with a side pressure positioning gasket 856. When inflating the airtight cavity 853, the piston connecting rod 855 can slide in the direction close to the vertical limit plate 122, and then can drive the side pressure positioning gasket 856 to move outwards, so that the side pressure positioning gasket 856 presses the vertical damping plate 851 outwards to realize the side pressure positioning of the support member A 810 and the support member B 820.

[0028] The side pressure positioning member 850 further includes a mounting sleeve 857 fixedly connected to the outside of the front chute 2 and a rectangular extrusion block 858 fixedly connected to the outside of the limit seat 121. The rectangular extrusion block 858 is located outside the support member A 810. An elastic airbag 859 is arranged inside the mounting sleeve 857. The top of the elastic airbag 859 is fixedly communicated with a communication hose A 860. One end of the communication hose A 860 away from the elastic airbag 859 is fixedly communicated with a communication hose B 861. Both ends of the communication hose B 861 extend into the airtight cavities 853 on both sides respectively. When the front straight window frame profile 7 and the arc-shaped window frame profile 4 are assembled to position the clamping member A 510, the rectangular extrusion block 858 can squeeze the elastic airbag 859 and inflate the inside of the airtight cavity 853 through the communication hose A 860 and the communication hose B 861.

[0029] Working principle of this embodiment: In this embodiment, the lateral assembly distance between the symmetric support frames 1, the vertical assembly distance between the clamping member A 510 and the clamping member B 610, and the vertical assembly distance between the support member A 810 and the support member B 820 are all adjustable. By moving one of the support frames 1, the adjustment of the lateral assembly distance can be realized. By synchronously starting the adjustment electro-hydraulic push rods 840 on both sides, the adjustment of the vertical assembly distance can be realized to adapt to the assembly positioning of arc-shaped door and window frames of different specifications.

[0030] The specific steps for quickly assembling the arc-shaped door and window frame in this embodiment are as follows: Step 1: Insertion of the corner fittings 9. Specifically: Insert the inner parts of the two ends of the two arc-shaped window frame profiles 4 into the corner fittings 9 respectively to assist the subsequent assembly work between the window frame profiles. Step 2: Placement of the window frame profiles. Specifically: First, place the two arc-shaped window frame profiles 4 in the middle rollers 563 on both sides in the front and the middle rollers 563 on both sides in the rear respectively. Due to the symmetry of the arc-shaped window frame profile 4, it is always symmetric about the center line of the symmetric support frame 1. That is, during the placement of the two arc-shaped window frame profiles 4, they will respectively squeeze the vertical limit plates 122 on both sides, so that the inner side surfaces of the vertical limit plates 122 are in contact with the outer side surfaces of the arc-shaped window frame profiles 4. Subsequently, place the two straight window frame profiles 7 on the support rollers 127 on both sides respectively, and ensure that the outer side surfaces of the straight window frame profiles 7 are in contact with the inner side surfaces of the limit blocks 126. Since the inner side surfaces of the limit blocks 126 coincide with the inner side surfaces of the vertical limit plates 122, the outer assembly surfaces between the arc-shaped window frame profiles 4 and the straight window frame profiles 7 coincide at this time. The schematic diagram after the operation is as Figure 8 shown; By first placing two arc-shaped window frame profiles 4 and then placing two straight window frame profiles 7, the outer assembly surfaces of the arc-shaped window frame profiles 4 can be automatically aligned with the outer assembly surfaces of the straight window frame profiles 7 placed on the support rollers 127, eliminating the step of manually aligning the outer assembly surfaces between the arc-shaped window frame profiles 4 and the straight window frame profiles 7, thereby accelerating the assembly between the arc-shaped window frame profiles 4 and the straight window frame profiles 7; Step Three: Clamping of the window frame profiles, specifically: By starting the clamping electro-hydraulic push rods 565 on both sides to extend, the clamping plates 566 on both sides clamp the front arc-shaped window frame profile 4 inside the front baffle 561, so as to realize the clamping function of the clamping member A 510 on the front arc-shaped window frame profile 4; Step Four: Partial assembly and positioning of the window frame profiles, specifically: Two workers push the limit block 126 inward with one hand and press and push the straight window frame profile 7 downward and forward with the other hand, so that the straight window frame profiles 7 on both sides can be aligned with the assembly surfaces at both ends of the arc-shaped window frame profile 4 and be clamped outside the corner codes 9 at both ends. Continuing to push the straight window frame profiles 7 on both sides forward, the front arc-shaped window frame profile 4 can be used to push the clamping member A 510, the support member A 810, the support member B 820, the clamping member B 610 and the rear arc-shaped window frame profile 4 to move forward synchronously (during the forward movement of the support member A 810, the rectangular extrusion block 858 can drive the elastic airbag 859 to be extruded, so that the gas inside the elastic airbag 859 enters the airtight cavities 853 on both sides through the connecting hose A 860 and the connecting hose B 861. The gas entering the airtight cavities 853 then pushes the piston connecting rod 855, so that the piston connecting rod 855 drives the side pressure positioning gasket 856 to move outward to contact the vertical damping plate 851), until the clamping member A 510 moves to abut against the inner wall of the front chute 2. At this time, the trapezoidal abutting block A 524 will abut against the outside of the rear baffle 562 for abutting and positioning, so as to prevent the clamping member A 510 from driving the front arc-shaped window frame profile 4 to move backward. The straight window frame profiles 7 on both sides are closely attached to the assembly surfaces at both ends of the arc-shaped window frame profile 4. At the same time, the side pressure positioning gaskets 856 on both sides press the vertical damping plate 851 outward to realize the side pressure positioning of the support member A 810 and the support member B 820, so that the support height of the support member A 810 and the support member B 820 for the straight window frame profile 7 is maintained constant, so as to prevent the position of the end of the straight window frame profile 7 close to the rear arc-shaped window frame profile 4 from shifting. In this way, the assembly and positioning between the front arc-shaped window frame profile 4 and the straight window frame profiles 7 on both sides can be completed. The schematic diagram after the operation is as Figure 9 shown; By synchronously pushing forward two straight window frame profile members 7, they can be closely fitted to the assembly surfaces at both ends of the arc-shaped window frame profile member 4. At the same time, the abutting positioning member 520 abuts and positions the clamping member A 510, so as to prevent the arc-shaped window frame profile member 4 in front in the clamping member A 510 from moving backward. And the side pressure positioning member 850 performs side pressure positioning on the support member A 810 and the support member B 820 to maintain the horizontal support height of the support member A 810 and the support member B 820 for the straight window frame profile member 7. That is, synchronously pushing forward two straight window frame profile members 7 can complete the assembly positioning between the front arc-shaped window frame profile member 4 and the two side straight window frame profile members 7; Step Five: Overall assembly positioning of the window frame profile members, specifically: Two workers synchronously push forward the rear arc-shaped window frame profile member 4 until the corner connectors 9 at both ends of the arc-shaped window frame profile member 4 are clamped inside the two side straight window frame profile members 7, and both ends of the arc-shaped window frame profile member 4 are closely fitted to the assembly surfaces of the two side straight window frame profile members 7 respectively. Subsequently, start the clamping electro-hydraulic push rods 565 on both sides to extend, so that the clamping plates 566 on both sides clamp the rear arc-shaped window frame profile member 4 inside the front baffle 561 (during the process of clamping the rear arc-shaped window frame profile member 4 after the clamping electro-hydraulic push rod 565 extends, the clamping plate 566 can drive the trapezoidal abutting block B 623 to move, and the trapezoidal abutting block B 623 slides in a direction away from the U-shaped elastic front and rear telescopic rod 830, which can abut the trapezoidal pressing block 624 and the pressing positioning gasket 625 to move downward, so that the pressing positioning gasket 625 presses the horizontal damping plate 621 downward, so as to realize the clamping effect of the clamping member B 610 on the rear arc-shaped window frame profile member 4 and the downward pressing and positioning effect of the downward pressing positioning member 620 on the clamping member B 610. In this way, the assembly positioning between the front and rear arc-shaped window frame profile members 4 and the two side straight window frame profile members 7 can be achieved, thus completing the overall assembly positioning of the window frame profile members. The schematic diagram after operation is as Figure 11 shown; By synchronously pushing forward two straight window frame profile members 7, they can be closely fitted to the assembly surfaces of the two side straight window frame profile members 7. Subsequently, when starting the clamping electro-hydraulic push rod 565 to clamp and position the rear arc-shaped window frame profile member 4, the downward pressing positioning member 620 can perform downward pressing and positioning on the clamping member B610, so as to realize the assembly positioning of the overall window frame profile members; Step Six: Overall assembly and fixation of the window frame profile members, specifically: Use tools to drive pins and sealant on the outer sides of the arc-shaped window frame profile member 4 and the straight window frame profile members 7 to fix the assembly between the arc-shaped window frame profile member 4 and the straight window frame profile members 7; Step Seven: Removal of the arc-shaped door and window frame, specifically: By activating the clamping electro-hydraulic push rods 565 on both sides to shorten and release the clamping effect of the clamping piece A 510 and the clamping piece B 610 on the arc-shaped window frame profile 4, the trapezoidal abutting block A 524 can slide towards the direction close to the return spring 530 and abut against the trapezoidal linkage block 522 and the trapezoidal positioning block 525 to move downward, thereby releasing the abutting and positioning effect of the abutting positioning piece 520 on the clamping piece A 510, so that the clamping piece A 510, the support piece A 810, the support piece B 820, the clamping piece B 610, and the arc-shaped door and window frame move backward synchronously, and the extrusion of the elastic airbag 859 to reset drives the side pressure positioning gaskets 856 on both sides to disengage from the vertical damping plate 851, so as to release the constant support effect of the support piece A 810 and the support piece B 820. At the same time, the stretched U-shaped elastic up-and-down telescopic plate 622 drives the downward pressure positioning gasket 625 to move upward and disengage from the horizontal damping plate 621, so as to release the downward pressure positioning effect of the downward pressure positioning piece 620 on the clamping piece B 610. Subsequently, the assembled arc-shaped door and window frame can be removed; By activating the clamping electro-hydraulic push rods 565 on both sides to shorten and release the clamping effect of the clamping piece A 510 and the clamping piece B 610 on the arc-shaped window frame profile 4, the abutting and positioning effect of the abutting positioning piece 520 on the clamping piece A 510, the constant support effect of the support piece A 810 and the support piece B 820, and the downward pressure positioning effect of the downward pressure positioning piece 620 on the clamping piece B 610 can be released, thereby realizing the rapid removal of the arc-shaped door and window frame; Subsequently, according to the above steps one to seven, the rapid assembly work of the next arc-shaped door and window frame can be carried out.

[0031] The main difference between this embodiment and the prior art is that: In this embodiment, there is no need for multiple workers to cooperate in positioning and clamping at the four corners. By placing the window frame profile in the corresponding position, the clamping piece A 510 clamps the front arc-shaped window frame profile 4, two workers push the two straight window frame profiles 7 and the rear arc-shaped window frame profile 4 forward synchronously, and the clamping piece B 610 clamps the rear arc-shaped window frame profile 4, the rapid assembly and positioning work of the arc-shaped door and window frame can be completed.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
