Description

[0002] Doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and leaf materials. They are called aluminum alloy doors and windows, or aluminum doors and windows for short. Fig.13 The common aluminum alloy doors and windows in the current price range are usually composed of aluminum alloy doors, window frames and windows. During production and assembly, it is necessary to use angle brackets or center brackets to achieve the installation between two mutually perpendicular window frame profiles. The specific method is usually to slide the angle bracket from one side of the groove body of the outer wall of the profile, and use screws to install it at the specified position of the profile, and then another vertical profile can be installed with the angle bracket;

[0003] During the above process, since the aluminum alloy plate constituting the window frame profile is relatively thin, the outer wall of the profile will be deformed by external force. When the workers are installing the center support and angle bracket, if the center support and angle bracket is skewed, it will squeeze the window frame profile, causing the profile to protrude outward to form an arc, affecting the subsequent installation of glass, doors and windows, and panels. In addition, during the current installation of the center support and angle bracket, it is often necessary to support the window frame profile to prevent it from moving. During this process, the force exerted by the outer wall can easily cause the window frame profile to deform inward, affecting its normal use.

[0004] Based on the above problems, this invention is proposed. Summary of the invention

[0014] In the above technical solution, an extended limiting plate is installed on the top of the limiting plate.

[0015] In the above technical solution, the present invention also provides a method for using an assembly device for aluminum alloy doors and windows, comprising the following steps:

[0016] Step 1. Place the window frame profile on the top of the workbench and limit the window frame profile through the limiting mechanism;

[0017] Step 2. Slide the center support bracket along the groove of the window frame profile to move it to a suitable position;

[0018] Step 3. Turn on the first motor to drive the first screw connected thereto to rotate, thereby moving the second movable seat screwed to the first screw, and then causing the connecting frame to drive the protective mechanism connected thereto to move together, and by adjusting the two second movable seats, the two protective mechanisms are respectively located at the positions on both sides of the middle support angle code;

[0027] c. When the free ends of the two first inner protective plates move away from each other in the step, the two driving rods will rotate synchronously with the rotation of the two first inner protective plates. The driving rods and the sleeves are used to drive the movable frame to move toward the direction of the first inner protective plates. When the outer supporting surface of the outer wall of the outer protective plate fits with the outer wall of the window frame profile, the outer wall of the window frame profile can be limited and supported.

[0029] 1. The present invention can make the two first inner protection plates expand outward synchronously by lowering the first mounting seat, and at the same time make the two movable frames drive the two outer protection plates to move inward synchronously, and then use the outer support surface and the first inner support surface to support and limit the outer wall and the inner wall of the window frame profile, so as to avoid deformation of the window frame profile;

[0030] Second, by using two first driving cylinders to drive the two first moving seats respectively, the two limit plates can be brought closer to each other, thereby achieving the clamping and limiting of the window frame profile and avoiding displacement and shaking during assembly operation;

[0031] 3. By extending the limiting plate or the supporting arm, the outer wall of the window frame profile at the middle support angle part can be limited, so as to prevent the middle support angle installed in the groove from shaking and causing the window frame profile to protrude outward and deform;

[0032] Fourth, the support mechanism can realize the support and limit of the window frame profile in the vertical direction. When the corner code of the horizontally placed window frame profile is installed, the vertical window frame profile can be stably placed to avoid shaking and displacement, and the position can be adjusted quickly and conveniently;

[0033] In summary, the present invention can provide limited support for the inner and outer walls of the window frame profile, thereby avoiding deformation of the profile due to the skewing or shaking of the angle brackets when installing the angle brackets, and can also realize the positioning of the window frame profile to avoid displacement during assembly. In addition, when assembling two mutually perpendicular window frame profiles, the longitudinally placed window frame profile can be positioned, thereby ensuring stability and reducing the labor cost of manual support and positioning.

DETAILED DESCRIPTION

[0053] The following is a combination of specific implementation cases and attached Figure 1-Figure 18 The present invention is further described below, but the present invention is not limited to these embodiments.

[0054] Embodiment 1:

[0055] like Fig.13 The figure shows an assembly diagram of the existing common aluminum alloy window frame profile 8 and the center support angle code 9, wherein the window frame profile 8 is a universal profile made of aluminum alloy thin plate. A groove capable of accommodating the center support angle code 9 or the center support angle code 9 is provided on one side of the window frame profile 8 where the center support angle code 9 is installed. The center support angle code 9 slides into the groove through one side, moves to the specified position, and is fixed and installed with screws. Subsequently, the window frame profile 8 is used as a horizontal frame, and the connecting function of the center support angle code 9 can be used to install another window frame profile 8 perpendicular to the horizontal frame to form a vertical frame. In this process, since the aluminum alloy plate constituting the window frame profile 8 is relatively thin, the outer wall of the profile will be deformed by the action of external force. When the worker is installing the center support angle code 9, if the center support angle code 9 is skewed, it will squeeze the window frame profile 8, causing the profile to protrude outward to form an arc, affecting the subsequent glass plate In addition, at the current stage, when installing the mid-support angle code 9, it is often necessary to support the window frame profile 8 to prevent it from moving. During this process, the force applied by the outer wall is also likely to cause the window frame profile 8 to deform inward. To address this problem, an assembly device for aluminum alloy doors and windows is proposed, including: a workbench 1 and a beam frame 2, wherein the workbench 1 can support and place the window frame profile 8, the beam frame 2 is installed on the top of the workbench 1, and the outer wall of the workbench 1 is equipped with several groups of limiting mechanisms 3 for clamping the window frame profile 8. The top of the workbench 1 is equipped with two groups of protective mechanisms 5, which can synchronously limit and support the inner and outer walls of the window frame profile 8 to avoid deformation, wherein the two groups of protective mechanisms 5 are assembled on the top of the workbench 1 through a moving mechanism 4, and the moving mechanism 4 can be used to enable the two groups of protective mechanisms 5 to move left and right respectively.

[0056] The following is an introduction to the protection mechanism 5, mainly referring to Figure 1-5 and Figure 7As shown in the figure, the protection mechanism 5 includes: a first mounting seat 51, a connecting plate 52, an extension plate 53, a moving frame 54, an outer protection plate 55, a first inner protection plate 56, a first spring 57, a second slideway 58, a pulley 59, a sleeve 510, a driving rod 511, a positioning rod 512 and a second driving cylinder 513. The connecting plate 52 is fixedly installed at the top end of the first mounting seat 51. The second driving cylinder 513 is installed at the top end of the connecting plate 52, and the output end of the second driving cylinder 513 is connected to the middle part of the outer wall of the connecting plate 52. Two extension plates 53 are symmetrically installed on the outer wall of the connecting plate 52 with respect to the center. A moving frame 54 is slidably embedded in the inner cavity of the extension plate 53. The moving frame 54 is arranged in a "U" shape with a through groove opened in the middle. An outer protection plate 55 is installed at the bottom end of the moving frame 54. Among them, the outer wall of the outer protection plate 55 facing the first mounting seat 51 is an outer support surface 55a. The outer wall of the outer support surface 55a is perpendicular to the outer wall of the workbench 1. When it moves, it can fit the outer wall of the window frame profile 8, and the joint is a plane, which can provide a stable supporting force. A sleeve 510 is rotatably installed in the inner cavity of the moving frame 54. A driving rod 511 is installed on the outer wall of the first inner protection plate 56, and the driving rod 511 is slidably embedded and penetrates through the inner cavity of the sleeve 510, and relative displacement can occur between the two. In addition, the driving rod 511 is inclined from bottom to top, and the bottom end of the driving rod 511 and the first inner protection plate 56 connected thereto are located on the same side of the first mounting seat 51. The two have the same angle and can rotate synchronously. When the driving rod 511 rotates, it can drive the moving frame 54 to move, and at the same time, displacement compensation is carried out by using the rotation of the sleeve 510 and the relative movement with the driving rod 511. Two first inner protection plates 56 are rotatably installed at the bottom end of the first mounting seat 51 through pins. The two extension plates 53 correspond to the two first inner protection plates 56 respectively, and the two first inner protection plates 56 can rotate respectively. When the first mounting seat 51 descends until the bottom ends of the outer walls of the two first inner protection plates 56 contact the limiting surface, the free ends of the two first inner protection plates 56 can expand horizontally outwards. The two ends of a first spring 57 are fixedly installed on the outer walls of the two first inner protection plates 56 respectively. The first spring 57 is a helical spring, which will undergo elastic deformation when being stretched or compressed, and will return to its initial state after the external force is removed. In the natural state, the free ends of the two first inner protection plates 56 can be kept in an expanded state by the action of the first spring 57, so that the two first inner protection plates 56 are arranged in a "V" shape. And in the natural state, the maximum width of the two first inner protection plates 56 is less than or equal to the inner cavity width of the groove of the middle muntin angle code 9 to be supported for the window frame profile 8;

[0057] In the above scheme, the first mounting seat 51, the first inner protective plate 56 and the first spring 57 constitute the inner support part, the connecting plate 52, the extension plate 53, the movable frame 54, the outer protective plate 55, the sleeve 510 and the driving rod 511 constitute the outer support part, and the inner support part and the outer support part can move toward each other or away from each other synchronously, so as to realize the synchronous position limiting of the outer wall of the outer wall of the window frame profile 8 to prevent deformation, wherein the outer wall of the first inner protective plate 56 opposite to the outer protective plate 55 is the first inner support surface 56a, and the first The inner supporting surface 56a is vertically arranged and parallel to the outer supporting surface 55a. When the two are close to each other, the outer supporting surface 55a can fit the outer wall of the window frame profile 8 and the inner wall at the same time. The bottom end of the first inner protective plate 56 is the first sliding surface 56b. The first sliding surface 56b is an arc surface, which reduces the contact area with the plane and reduces the friction. When the first mounting seat 51 descends and the first inner protective plate 56 contacts the plane at its bottom end, the two first inner protective plates 56 can expand outward.

[0058] In order to provide a limit for the movable frame 54 and ensure that it can only move horizontally, the following scheme is proposed: a positioning rod 512 is installed in the inner cavity of the extension plate 53, the positioning rod 512 is parallel to the upper surface of the workbench 1, and the outer wall of the positioning rod 512 slides through the inner cavity of the movable frame 54. The positioning rod 512 is used to limit the movable frame 54, so as to ensure that the movable frame 54 can only move in the horizontal direction, thereby ensuring the stable movement of the outer protective plate 55. In addition, a second slide 58 is provided on the outer wall of the extension plate 53, and a pulley 59 is installed on the outer wall of the movable frame 54, and the pulley 59 is rolled and embedded in the inner cavity of the second slide 58. The movable frame 54 and the positioning rod 512 can be symmetrically arranged in two groups. When the movable frame 54 moves, the movable frame 54 can roll in the inner cavity of the second slide 58, which is convenient for movement and can further provide support.

[0059] The following is an introduction to the mobile mechanism 4, mainly referring to Figure 1-Figure 5The moving mechanism 4 includes: a fixed frame 41, a first screw 42, a second limiting rod 43, a second moving seat 44, a screw hole 45, a first through hole 46, a second through hole 47, a connecting frame 48 and a first motor 49. The two fixed frames 41 are symmetrically installed on the top of the workbench 1. Two first screws 42 are rotatably installed between the two fixed frames 41. A second limiting rod 43 is fixedly installed between the two fixed frames 41. Two second moving seats 44 are slidably mounted on the outer wall of the second limiting rod 43. The second limiting rod 43 can limit the second moving seat 44 to ensure that the second moving seat 44 can only move relative to the second The limiting rod 43 moves axially, and the outer wall of the second movable seat 44 is respectively provided with a screw hole 45, a first through hole 46 and a second through hole 47. The inner cavity of the first through hole 46 provided on the outer wall of the second movable seat 44 is slidably penetrated by the second limiting rod 43. The inner wall of the screw hole 45 provided on the outer wall of one of the second movable seats 44 is screwed with the outer wall of one of the first lead screws 42, and the screw hole 45 provided on the outer wall of the other second movable seat 44 is screwed with the other first lead screw 42, so as to ensure that when the two first lead screws 42 rotate, only the second movable seat 44 screwed therewith can be driven to move without affecting the other second movable seat The second movable seat 44 is provided with a second limiting rod 43, and the second limiting rod 43 limits the second movable seat 44 to prevent the second limiting rod 43 from rotating. In addition, the position of the second through hole 47 on the outer wall of the second movable seat 44 corresponds to the position of the first lead screw 42 which is not screwed thereto, and the diameter of the second through hole 47 is larger than the diameter of the screw hole 45, so as to ensure that the second movable seat 44 does not contact the first lead screw 42 which is not screwed thereto, and to avoid interference during operation. The outer walls of the two fixed frames 41 are both installed with first motors 49, and the output ends of the two first motors 49 are respectively connected to the two first lead screws 42 through couplings, so as to ensure that the two first lead screws 42 A motor 49 can independently drive the two first lead screws 42 to rotate respectively. A connecting frame 48 is installed on the outer wall of the second movable seat 44. A second driving cylinder 513 is installed on the end of the connecting frame 48 away from the second movable seat 44, and the output end of the second driving cylinder 513 is fixedly connected to the top of the connecting plate 52. Turning on the second driving cylinder 513 can drive the connected connecting plate 52 and the first mounting seat 51 to rise and fall. The second driving cylinder 513 uses a self-locking cylinder or an electric push rod with self-locking capability. It is an existing equipment, and the model can be selected such as: LAP electric push rod, etc., which can meet the driving requirements.

[0060] The following is an introduction to the limit mechanism 3, mainly referring to Figure 1 , Figure 2 and Figure 6The limiting mechanism 3 includes: two symmetrically arranged limiting plates 31, the outer walls of the two limiting plates 31 on one side are arranged perpendicular to the outer wall of the workbench 1, in addition, the limiting mechanism 3 also includes: a first slide 32, a first movable seat 33, a first driving cylinder 34 and a first limiting rod 35, the number of the first slides 32 is two, which are symmetrically opened on the outer wall of the workbench 1, and the first movable seats 33 are slidably embedded in the inner cavities of the two first slides 32, the top of the first movable seat 33 is fixedly connected to the limiting plate 31, and the bottom end of the first movable seat 33 extends out of the bottom end of the inner cavity of the first slide 32, the number of the first driving cylinder 34 is two, which are symmetrically installed on the bottom end of the workbench 1, and the output ends of the two first driving cylinders 34 are fixedly installed on the outer walls of the two first movable seats 33, respectively. The first driving cylinder 34 uses a self-locking cylinder or an electric push rod with self-locking ability. It is an existing equipment, and the model can be selected as: LAP electric push rod, etc., which can meet the driving requirements. Opening the first driving cylinder 34 can push the first The movable seat 33 is used in the inner cavity of the first slide 32, thereby driving the two limiting plates 31 to clamp the inner profile. In order to increase the stability of the first movable seat 33, a first limiting rod 35 parallel to the upper surface of the workbench 1 can be set in the inner cavity of the first slide 32, and the first limiting rod 35 is slid through the outer wall of the first movable seat 33, and then the limiting left and right effect of the first limiting rod 35 is utilized to ensure that the moving direction of the first movable seat 33 is consistent with the axial direction of the first limiting rod 35 to avoid shaking. In addition, Two limit grooves 33a can be symmetrically opened on the outer wall of the first movable seat 33. The two limit grooves 33a slide and engage with the inner wall of the first slide 32, which can also ensure the stability of the first movable seat 33 when sliding. In this scheme, the first slide 32, the first movable seat 33, the first driving cylinder 34 and the first limit rod 35 constitute a clamping driving part that drives the two limit plates 31 to move closer to or away from each other. The two limit plates 31 can be driven by the clamping driving part to approach each other and clamp the window frame profile 8 between them.

[0061] It is worth noting that in the above scheme, the two first drive cylinders 34 in each group can be controlled by a PLC controller to ensure that the two first drive cylinders 34 are started synchronously, thereby ensuring that the two limit plates 31 can move synchronously close to or away from each other. In addition, the position of the first mounting seat 51 corresponds to the position of the two limit plates 31. After the two limit plates 31 clamp the window frame profile 8, the center line of the first mounting seat 51 is aligned with the center line of the window frame profile 8, ensuring that the outer walls on both sides of the profile can be limited synchronously.

[0062] The present invention also provides a method for using the assembly equipment for aluminum alloy doors and windows:

[0063] The steps include:

[0064] Step 1. Place the window frame profile 8 on the top of the workbench 1, and limit the window frame profile 8 by the limiting mechanism 3;

[0065] Step 2. Slide the middle corner code 9 along the groove of the window frame profile 8 to move it to a suitable position;

[0066] Step 3. Turn on the first motor 49 to drive the first screw 42 connected thereto to rotate, so that the second movable seat 44 screwed to the first screw 42 moves, and then the connecting frame 48 drives the protective mechanism 5 connected thereto to move together, and by adjusting the two second movable seats 44, the two protective mechanisms 5 are respectively located at the positions on both sides of the middle corner code 9;

[0067] Step 4. The inner and outer walls of the window frame profile 8 are supported by two protective mechanisms 5;

[0068] Step 5. Fix the center support angle code 9 with screws.

[0069] Step 1 includes the following steps:

[0070] S1. Place the window frame profile 8 on the top of the workbench 1 to ensure that the window frame profile 8 is located between the two limit plates 31;

[0071] S2. Synchronously start the two first driving cylinders 34 to move the two first moving seats 33 toward each other along the two first slideways 32, so that the two limit plates 31 are close to each other to clamp the window frame profile 8 in the center.

[0072] Step 4 includes the following steps:

[0073] a. Open the second drive cylinder 513 to drive the first mounting base 51 down until the first inner protective plate 56 enters the groove of the window frame profile 8;

[0074] b. After the first sliding surface 56b at the bottom end of the first inner protection plate 56 contacts the bottom end of the inner cavity of the groove of the door and window frame profile 8, the second driving cylinder 513 continues to drive the first mounting seat 51 to descend, so that the free ends of the two first inner protection plates 56 move away from each other until the first inner support surface 56a contacts the inner wall of the window frame profile 8 to achieve inner support limit;

[0075] c. When the free ends of the two first inner protective plates 56 move away from each other in step b, the two driving rods 511 will rotate synchronously with the rotation of the two first inner protective plates 56. The driving rods 511 and the sleeve 510 cooperate to drive the movable frame 54 to move toward the direction of the first inner protective plates 56. When the outer supporting surface 55a of the outer wall of the outer protective plate 55 fits with the outer wall of the window frame profile 8, the outer wall of the window frame profile 8 can be limited and supported.

[0076] The working principle of an assembly device for aluminum alloy doors and windows in the present embodiment is as follows: the aluminum alloy window frame profile 8 is placed on the top of the workbench 1, and the groove for installing the center support angle code 9 is ensured to face upward, and the outer wall of the center support angle code 9 is located between the two limit plates 31, and the two first driving cylinders 34 are synchronously turned on to drive the two first moving seats 33 to slide along the inner cavities of the two first slideways 32 respectively, so that the two limit plates 31 are close to each other to clamp the outer wall of the window frame profile 8, and then the center support angle code 9 is slid in from one side of the window frame profile 8, and the center support angle code 9 is moved to the specified position, and then the two first motors 49 are turned on to make the two first lead screws 42 rotate respectively, so that the two second moving seats 44 are respectively moved to the two sides of the center support angle code 9, and the second driving cylinder 513 is turned on. The connecting plate 52 and the first mounting seat 51 descend, and the first inner protective plate 56 enters the inner cavity of the window frame profile 8 groove. When the first sliding surface 56b contacts the inner wall of the profile, under the action of external force, the two first inner protective plates 56 will begin to rotate and their free ends will expand to both sides. At the same time, the driving rod 511 will rotate together. At this time, the sleeve 510 slides on the outer wall of the driving rod 511, and the movable frame 54 moves toward the direction of the first mounting seat 51, thereby making the outer protective plate 55 move toward the direction of the first mounting seat 51. When the outer supporting surface 55a and the first inner supporting surface 56a are respectively in contact with the outer wall and the inner wall of the window frame profile 8, they can provide a limit to prevent the outer wall of the position area of ​​the corner code 9 during the installation of the window frame profile 8 from deforming inward or outward.

[0077] Embodiment 2:

[0078] This embodiment mainly refers to Fig.10 , which is different from Example 1 in that: the outer wall of the outer protective plate 55 is also provided with an extended support arm 55b, which is arranged on the opposite side of the two sets of protective mechanisms 5, and the length of the extended support arm 55b is 3-5cm. The setting of the extended support arm 55b can increase the support area for the outer wall of the window frame profile 8. When in use, the middle support angle code 9 is pre-slid into the groove of the window frame profile 8, and then the distance between the two protective mechanisms 5 is adjusted so that the free ends of the extended support arms 55b corresponding to the positions in the two sets of protective mechanisms 5 are in contact with each other, and the extended support arm 55b is used to support the outer wall portion of the window frame profile 8 corresponding to the position of the middle support angle code 9, so as to further prevent the deformation of the window frame profile 8 caused by the shaking or skewing of the middle support angle code 9. In addition, when the two sets of protective mechanisms 5 are used for limited support, a space of 6-10cm is reserved between the two sets of protective mechanisms 5, which is sufficient for the staff to install the atrium angle code using screws.

[0079] Embodiment three:

[0080] This embodiment mainly refers to Fig.11 and Fig.12, which is different from Example 1 in that: the protection mechanism 5 includes: a second mounting seat 5101, the middle part of the top end of the second mounting seat 5101 is connected to the output end of the second driving cylinder 513, and the bottom end of the second mounting seat 5101 is rotatably mounted with two second inner protection plates 5601 through a pin shaft, and the two second inner protection plates 5601 can rotate separately, and when the second mounting seat 5101 descends so that the bottom ends of the outer walls of the two second inner protection plates 5601 contact the limiting surface, the free ends of the two second inner protection plates 5601 can expand horizontally outward, and the two second inner The outer wall of the protection plate 5601 is respectively fixed with two ends of the second spring 5701. The second spring 5701 is a spiral spring. It will be elastically deformed when stretched or squeezed, and will return to its original state after the external force is removed. In the natural state, the second spring 5701 can be used to ensure that the free ends of the two second inner protection plates 5601 are in an expanded state, so that the two second inner protection plates 5601 are arranged in a "human" shape, and in the natural state, the maximum width of the two second inner protection plates 5601 is less than or equal to the inner width of the groove of the middle support bracket 9 for installing the window frame profile 8 to be supported. The second inner protective plate 5601 has a second inner support surface 5601a on its outer wall, which is parallel to the inner wall of the window frame profile 8 to be supported. When it fits the inner wall of the outer wall of the window frame profile 8, it can support and limit the inner wall of the window frame profile 8. The bottom end of the second inner protective plate 5601 is a second sliding surface 5601b, which is an arc surface to reduce the contact area with the plane and reduce the friction. When the second mounting seat 5101 descends, the second inner protective plate 5601 contacts the plane at its bottom end. To facilitate the outward expansion of the two second inner protection plates 5601, when in use, the second driving cylinder 513 drives the second mounting seat 5101 to descend, and then the second inner protection plates 5601 enter the inner cavity of the groove of the window frame profile 8. When the second sliding surface 5601b contacts the inner wall of the profile, under the action of external force, the two second inner protection plates 5601 will start to rotate and their free ends will expand to both sides. When the second inner supporting surface 5601a is in contact with the inner wall of the window frame profile 8, it can provide a limit position to prevent the outer wall of the position area of ​​the angle bracket 9 during the installation of the window frame profile 8 from deforming inward.

[0081] In addition, when the window frame profile 8 is clamped by the limiting mechanism 3, it is necessary to ensure that the position of the limiting plate 31 corresponds to the placement position of the center support angle code 9, and an extended limiting plate 31a is installed at the top of the limiting plate 31, wherein the extended limiting plate 31a is coplanar with the outer wall of the limiting plate 31, and the total height of the limiting plate 31 and the extended limiting plate 31a is not less than the height of the clamped window frame profile 8. The extended limiting plate 31a and the outer wall of the limiting plate 31 can be used to support and limit the window frame profile 8 with the center support angle code 9 installed to avoid outward deformation of the window frame profile 8. In this way, it can be ensured that the inner and outer walls of the window frame profile 8 are limited to avoid deformation.

[0082] Embodiment 4:

[0083] This embodiment mainly refers to Figure 1-Figure 9, which is different from Example 1 in that: the assembly equipment of the aluminum alloy doors and windows also includes: a third limiting rod 6 and a supporting mechanism 7, which are used to clamp and limit the profile perpendicular to the window frame profile 8 placed on the top of the workbench 1 to avoid shaking during installation and eliminate the labor cost of manual limiting. The number of the third limiting rods 6 is two groups, which are symmetrically installed on the inner side of the beam frame 2, and the number of each group of third limiting rods 6 is two. A supporting mechanism 7 is installed between the two groups of third limiting rods 6, wherein the supporting mechanism 7 includes: two symmetrically arranged third moving seats 71, and the two third moving seats 71 are respectively slidably sleeved on the outer walls of the left and right groups of third limiting rods 6, and the left and right sides of the beam frame 2 are respectively installed with third driving cylinders 72, and the third driving cylinders 72 The output end is fixedly connected to the middle part of the outer wall of the third movable seat 71. Turning on the third driving cylinder 72 can drive the third movable seat 71 to move. At the same time, the third movable seat 71 is kept stable by using the third limiting rod 6. Two fourth limiting rods 73 are symmetrically installed between the two third movable seats 71. The outer walls of the two fourth limiting rods 73 are slidably sleeved on the upper and lower ends of the outer wall of the fourth movable seat 75 respectively. A second lead screw 74 is also rotatably installed between the two third movable seats 71, and the middle part of the outer wall of the fourth movable seat 75 is screwed to the outer wall of the second lead screw 74. A fourth motor 714 is installed on the outer wall of one of the third movable seats 71, and the output end of the fourth motor 714 is connected to one end of the second lead screw 74 through a coupling. Turning on the fourth motor 714 The fourth movable seat 75 can be stably moved by utilizing the limiting position of the fourth limiting rod 73. A fifth limiting rod 76 is provided on the inner side of the fourth movable seat 75 in the up-down direction. A lifting seat 79 is slidably sleeved on the outer wall of the fifth limiting rod 76. A second motor 77 is installed on the top of the fourth movable seat 75. A third leading screw 78 is rotatably installed on the inner side of the fourth movable seat 75 in the up-down direction. The top of the third leading screw 78 is connected to the output end of the second motor 77 through a coupling. The outer wall of the lifting seat 79 is screwed to the outer wall of the third leading screw 78. Turning on the second motor 77 can drive the third leading screw 78 to rotate, thereby causing the lifting seat 79 to move up and down. At the same time, utilizing the limiting position of the fifth limiting rod 76, The lifting seat 79 remains stable, and a connecting seat 710 is installed on the outer wall of the lifting seat 79. A third slideway 712 is provided on the outer wall of the connecting seat 710. Two moving blocks 713 are symmetrically and slidably embedded in the inner cavity of the third slideway 712. A screw rod 711 is rotatably installed on the inner side of the connecting seat 710. The threads on the left and right sides of the outer wall of the screw rod 711 are positive and negative threads, and the outer walls of the two moving blocks 713 are screwed to the left and right sides of the outer wall of the screw rod 711. When the screw rod 711 rotates, the two moving blocks 713 can synchronously approach or move away from each other. A fifth motor 715 is installed on the outer wall of the connecting seat 710. The output end of the fifth motor 715 is connected to one end of the screw rod 711 through a coupling. Turning on the fifth motor 715 can drive the screw rod 711 to rotate.

[0084] The outer wall of the moving block 713 located in the inner cavity of the third slideway 712 is adapted to the inner cavity of the third slideway 712. The limit of the inner wall of the third slideway 712 can prevent the moving block 713 from shaking or rotating. In addition, the front outer wall of the moving block 713 is provided with a clamping arm made of hard rubber, and its length in the vertical direction is not less than 20 cm. The hard rubber material can avoid scratching the outer wall of the window frame profile 8, and at the same time avoid the contact area between the two being too small, thereby ensuring the stability of the limit.

[0085] The working principle of this embodiment is as follows: first, refer to the placement of embodiment 1 to limit the window frame profile 8 placed on the top of the workbench 1, and install the middle corner code 9. The window frame profile 8 is a horizontal frame. Then, another window frame profile 8 is placed vertically and docked with the middle corner code 9. This window frame profile 8 is a vertical frame. Then, the third driving cylinder 72 is turned on to drive the third movable seat 71 to move forward and backward, and the fourth motor 714 is turned on to drive the second screw 74 to rotate, so that the fourth movable seat 75 moves left and right. At the same time, the third screw 78 is rotated by the rotation of the second motor 77, so that the lifting seat 79 drives the connecting seat 710 to move up and down, so that the two moving blocks 713 correspond to the outer wall of the vertical frame, and the fifth motor 715 is turned on to rotate the screw 711, so that the two moving blocks 713 are close to each other. When the moving blocks 713 are in contact with the outer wall of the vertical frame, the clamping and limiting of the vertical frame can be realized to prevent the vertical frame from shaking. At this time, the horizontal frame, the vertical frame, and the middle corner code 9 can be fixed to each other by screws.

[0086] In addition, if Fig.14 As shown, when it is necessary to assemble the longitudinal frame at the end of the transverse frame, one of the protective mechanisms 5 can be used to support and limit the inner and outer walls of the profile, so as to install the angle code, and then the supporting mechanism 7 can be used to support the longitudinal frame to achieve stable assembly.

[0087] Embodiment five:

[0088] like Figure 5 As shown, in actual work, the center support angle code 9 is mostly divided into two symmetrical and independent parts. When installing, the staff manually slides the two parts in and cannot ensure that the two independent parts are symmetrical and flush. If so, after the screws are tightened and fixed, the two parts of the center support angle code 9 will have deviations, which may easily lead to the situation that the longitudinal frame cannot be connected in the subsequent installation. To solve the above problem, refer to Figure 15-18 The following proposal is now proposed:

[0089] The present embodiment is different from the embodiments 1-4 in that it further comprises: two symmetrically mounted flush push plates 10, the width of the flush push plates 10 being adapted to the width of the slot for placing the center brace angle code 9 in the window frame profile, the two flush push plates 10 being rotatably mounted on the outer walls of the two first mounting seats 51 on opposite sides thereof through the pin shafts, and the outer walls of the pin shafts being sleeved with torsion springs 11, the two ends of the torsion springs 11 being fixedly mounted on the outer walls of the first mounting seats 51 and on the opposite sides of the flush push plates 10 and the first mounting seats 51, respectively, the flush push plates 10 The flat push plate 10 is tilted from bottom to top in a direction away from the first mounting seat 51. When no external force is applied, the distance between the top of the flat push plate 10 and the first mounting seat 51 is greater than or equal to 5 cm, ensuring that when the positions of the two protective mechanisms 5 and the middle support angle code 9 are adjusted to a suitable state, as the protective mechanism 5 descends, the flat push plate 10 can fit the outer wall of the middle support angle code 9. A slide groove 12 is installed on the outer wall of the side opposite to the first mounting seat 51. The outer wall of the slide groove 12 is also provided with a through groove. The slide groove 12 is provided with a through groove. 2 is slidably embedded with a slide sheet 13a, and a pull rod 13 is fixedly installed on the outer wall of the slide sheet 13a. The pull rod 13 slides through the inner cavity of the through groove and the outer wall of the first mounting seat 51 in turn. When the flush push plate 10 rotates, it can drive the pull rod 13 to slide relative to the outer wall of the first mounting seat 51. At the same time, the cooperation of the slide groove 12 and the slide sheet 13a is used to compensate for displacement to avoid interference. An adjustment mechanism 14 that can actively adjust the relative distance between the pull rod 13 and the first mounting seat 51 is provided on the side of the first mounting seat 51 away from the flush push plate 10. When the flush push plates 10 on the two protective mechanisms 5 are simultaneously attached to the two sides of the middle support angle code 9, it can ensure that the two components in the middle support angle code 9 are flush and aligned. At this time, the adjustment mechanism 14 on one protective mechanism 5 can be used to actively adjust the flush push plate 10, and at the same time, the other flush push plate 10 is passively adjusted, so that the lateral position of the middle support angle code 9 can be fine-tuned, and it can be ensured that the two components of the middle support angle code 9 are always symmetrical and flush during the fine-tuning process;

[0090] The following is an introduction to the adjustment mechanism 14, which includes: a sleeve 1401, the sleeve 1401 is slidably sleeved on the end of the pull rod 13 away from the flush push plate 10, and the end of the sleeve 1401 away from the first mounting seat 51 is equidistantly provided with a plurality of extension pieces 1402 along the circumferential direction, the outer wall of the side of the extension piece 1402 away from the pull rod 13 is flush with the outer wall of the sleeve 1401, and a top block 1403 is installed on the side of the extension piece 1402 opposite to the pull rod 13, the total thickness of the extension piece 1402 and the top block 1403 is greater than or equal to the wall thickness of the sleeve 1401, and the sleeve 1401 is close to the extension piece 1402. The outer wall of one end of the sleeve 1401 is provided with a first thread 1401a, and the outer wall of the end of the sleeve 1401 away from the extension piece 1402 is provided with a second thread 1401b. The outer wall of the sleeve 1401 is rotatably sleeved with the limiting cylinder 1404, and the inner wall of the limiting cylinder 1404 is provided with a third thread 1404a adapted to the first thread 1401a at one end away from the extension piece 1402, and the two are threadedly connected. When the limiting cylinder 1404 rotates, it can move along the outer wall of the sleeve 1401, and the inner wall of the limiting cylinder 1404 close to the extension piece 1402 is a limiting wall 1404b, and the limiting wall 1404b The sleeve 1401 is fitted with the limiting wall 1404b of the limiting cylinder 1404, and when the limiting wall 1404b of the limiting cylinder 1404 completely covers the extension piece 1402, the top block 1403 will press against the outer wall of the pull rod 13, so that the sleeve 1401 and the pull rod 13 are fixed to each other. The outer wall of the end of the sleeve 1401 away from the extension piece 1402 is also provided with two limiting blind grooves 1401c. The outer wall of the end of the sleeve 1401 away from the extension piece 1402 is sleeved with a fixing cylinder 1405, and the fixing cylinder 1405 is fixedly connected to the first mounting seat 51. The inner wall of the fixing cylinder 1405 is provided with two sliding blocks 1405a, and the sliding blocks 1405 a is slidably embedded in the inner cavity of the limiting blind groove 1401c, and the cooperation of the slider 1405a and the limiting blind groove 1401c can ensure that the fixed cylinder 1405 and the sleeve 1401 do not rotate relative to each other. The end of the fixed cylinder 1405 away from the first mounting seat 51 is rotatably mounted with a rotating cylinder 1406 through a bearing. The inner wall of the rotating cylinder 1406 is provided with a fourth thread 1406a adapted to the second thread 1401b, and the two are threadedly connected. Rotating the rotating cylinder 1406 can move the sleeve 1401. When the sleeve 1401 and the pull rod 13 are fixed to each other, the pull rod 13 can be driven to move.

[0091] The working principle of this embodiment to achieve the alignment of the two independent parts of the middle angle bracket 9 is as follows:

[0092] During the synchronous descent of the two protection mechanisms 5, the two flush push plates 10 will contact the outer wall of the middle support angle code 9. When the two flush push plates 10 contact the middle support angle code 9 at the same time, they continue to descend, and the middle support angle code 9 is used to limit the two flush push plates 10 to rotate respectively, and at the same time compress the torsion spring 11, and the pull rod 13 slides on the outer wall of 51. When the protection mechanism 5 is embedded in the side groove of the window frame profile 8, the two flush push plates 10 simultaneously fit the two sides of the two parts of the middle support angle code 9. At this time, the two parts are symmetrically flush. Then, the limiting cylinder 1404 set on one of the protection mechanisms 5 is rotated to slide along the outer wall of the sleeve 1401 toward the direction of the extension piece 1402. When the limiting cylinder 1404 covers the outer wall of 1042, it will tightly press the top block 1 403 makes it hug the outer wall of the pull rod 13. At this time, the sleeve 1401 and the pull rod 13 are fixedly connected. Rotating the rotating cylinder 1406 can make the sleeve 1401 and the pull rod 13 move together, and then use the pull rod 13 to pull or push the leveling push plate 10 to rotate. When the pull rod 13 that actively adjusts the position pulls the leveling push plate 10 toward the first mounting seat 51, at this time, the other leveling push plate 10 is passively rotated by the elastic force of the torsion spring 11, so that the two components of the center support angle code 9 are synchronously moved in the active adjustment direction, and then the center support angle code 9 can be stably fine-tuned in the horizontal direction. Conversely, when the pull rod 13 is actively adjusted to push the leveling push plate 10 to rotate away from the first mounting seat 51, the center support angle code 9 can be fine-tuned in another direction.

[0093] This embodiment scheme can not only automatically realize the mutual symmetry and alignment of the two independent components of the center support angle code 9 to avoid misalignment during installation, but also realize the fine adjustment of the position of the center support angle code after the alignment operation, and the operation is simple and practical.

[0094] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
