Description

Technical Field

[0001] The present invention relates to the technical field of side frame assembly, and specifically discloses a pressing device for side frame production and assembly. Background Art

[0002] The side frame, that is, the frame of a glass window or a glass door, is used for glass installation and also has a certain protective effect on the glass. Commonly used side frames are mostly made of materials such as aluminum alloy, broken bridge aluminum, and plastic steel. The side frame includes two groups of short beams and two groups of long beams. The connection methods between adjacent short beams and long beams include corner joint (angle code) connection, welding assembly, bolt fixation, etc.; among them, when using corner joint connection, bolts can be used to fix the corner joint, or the corner joint is in interference fit with the short beam and the long beam, that is, the corner joint is directly pressed into from the end of the short beam or the long beam, so as to generate sufficient radial pressure and friction force to ensure that the corner joint does not loosen or fall off in the aluminum beam cavity; when using the interference fit method to connect the corner joint with the short beam or the long beam, a pressing machine is needed to push the corner joint so that both sides of the corner joint are pressed into from the ends of the short beam and the long beam respectively. A positioning block for positioning the corner joint is provided on the pressing machine to prevent the corner joint from tilting or shifting during the pressing process, resulting in deformation of the aluminum beam.

[0003] For example, the patent with the publication number CN208483482U, the publication date is February 12, 2019, which discloses a seamless corner assembling machine for window frames, including a chassis. Motor mounting seats and support seats are provided on both sides of the chassis. A splicing bracket is provided between the motor mounting seat and the support seat. Fixed frames and movable frames are provided on both sides of the splicing bracket. Fixed corner assembling devices and movable corner assembling devices are provided on both the fixed frame and the movable frame. The fixed corner assembling device and the movable corner assembling device both include a bottom plate, a corner assembling component, a top corner component and a pressing mechanism located on the bottom plate. The top corner component is provided on the side opposite to the corner assembling component, and the pressing mechanism is provided above the corner assembling component. A seamless corner assembling machine for window frames overcomes the problems of slow manual corner assembling speed, unstable product quality, and easy occurrence of situations such as non-straightness, non-parallelism or misalignment, and has high automation and high production efficiency.

[0004] In the process of using a press to connect the corner joint with the short beam and the long beam, the pushing of the corner joint is divided into two directions, namely along the axial direction of the short beam and the axial direction of the long beam. In the prior art, the positioning block is usually fixedly installed on the support block, and the support block is slidably connected to the bottom plate (the support block slides along the axial direction of the short beam), and the bottom plate is further slidably connected to the workbench (the bottom plate slides along the axial direction of the long beam). Among them, both the support block and the bottom plate and both the bottom plate and the workbench use the cooperation of the slider and the guide rail to achieve sliding connection. A first cylinder for driving the bottom plate to move is arranged on the workbench, and a second cylinder for driving the support block to move is arranged on the bottom plate; however, since the corner joint is in interference fit with both the long beam and the short beam, a sufficiently large extrusion force is required to realize the connection between the corner joint and the long beam and the short beam. This leads to a large force on the guide rail at the connection between the bottom plate and the workbench when pushing the support block along the axial direction of the short beam, and a large force on the guide rail at the connection between the support block and the bottom plate when pushing the bottom plate along the axial direction of the long beam. The large force will cause the guide rail to loosen or deform, and once the guide rail loosens or deforms, the position of the positioning block will shift, resulting in the corner joint being unable to align with the end of the long beam or the short beam; on the other hand, in the process of pushing the bottom plate to drive the support block to move along the axial direction of the long beam, the force application height of the bottom plate is lower than the height of the positioning block. Therefore, the reaction force from the corner joint received by the positioning block is not in the same straight line as the thrust received by the bottom plate, resulting in a large shear force on the slider connecting the support block and the bottom plate. While the sliding resistance increases, the slider also has a tendency to disengage from the guide rail, which is not conducive to the connection between the corner joint and the short beam or the long beam. Summary of the Invention

[0005] The object of the present invention is to provide a pressing device for side frame production and assembly.

[0006] In order to achieve the above object, the present invention provides the following technical solutions: A pressing device for side frame production and assembly includes a support frame. Positioning components for positioning the corner joint are arranged at the four corner positions of the support frame. The positioning component includes a support block slidably installed on the support frame. A positioning block is fixedly connected to the support block. The support block has a first stroke along the axial direction of the short beam and a second stroke along the axial direction of the long beam. A driving member is also arranged on the support frame. The driving member drives the support block to sequentially pass through the first stroke and the second stroke to realize the connection between the corner joint and the short beam and the long beam.

[0007] In the above pressing device, support seats are installed at the four corner positions of the support frame. The support block is slidably connected to the support seat. A rotating ring is rotatably installed on each support seat. The driving member includes a first cylinder fixedly connected to each rotating ring. The first cylinder is arranged along the radial direction of the corresponding rotating ring. When the first stroke of the support block ends, it coincides with the center line of the corresponding rotating ring.

[0008] In the above-mentioned pressing device, the supporting block is a cylinder, and a connecting piece is arranged on the supporting block. The output end of the first cylinder is connected to the connecting piece, and the connecting piece can rotate around the central axis of the supporting block.

[0009] In the above-mentioned pressing device, the positioning block includes a limiting block for limiting the outside of the docking angle and a limiting rod for limiting the inside of the docking angle. The cross-section of the limiting block is L-shaped, the cross-section of the limiting rod is rectangular, and the diagonals of the limiting block and the limiting rod coincide.

[0010] In the above-mentioned pressing device, the limiting rod is rotatably connected to the supporting block through a first rotating shaft. A receiving groove for accommodating the limiting rod is formed on the supporting block, and the limiting rod is driven to rotate into the receiving groove to cancel the limitation of the inside of the docking angle.

[0011] In the above-mentioned pressing device, the cross-section of the limiting rod is square, a diagonal of the cross-section of the limiting rod coincides with the diagonal of the limiting block, and the rotation axis of the limiting rod is parallel to the other diagonal of its cross-section.

[0012] In the above-mentioned pressing device, a transmission member is arranged inside the supporting block. When the first cylinder extends, it first drives the limiting rod to rotate outwards from the receiving groove through the transmission member. When the first cylinder contracts, it first drives the limiting rod to rotate into the receiving groove through the transmission member.

[0013] In the above-mentioned pressing device, the transmission member includes a second rotating shaft rotatably installed inside the supporting seat. The central axes of the second rotating shaft and the supporting block coincide, and a first bevel gear is fixedly connected to the upper end of the second rotating shaft. A second bevel gear is sleeved outside the first rotating shaft. The first bevel gear and the second bevel gear are meshed with each other. A spur gear is sleeved in the middle of the second rotating shaft. The output end of the first cylinder is fixedly connected with a rack, and the rack and the spur gear are meshed with each other.

[0014] In the above-mentioned pressing device, a support plate is installed on the supporting block along the length direction of the short beam. A baffle is fixedly connected to one side of the upper surface of the support plate, and a stop rod is rotatably installed on the other side of the upper surface of the support plate. A torsion spring capable of maintaining the stop rod in a vertical state is arranged at the hinged position of the stop rod and the support plate.

[0015] In the above-mentioned pressing device, a pressing assembly for positioning the long beam is arranged on the support frame. The pressing assembly includes a fixed part fixedly connected to the support frame and an adjusting part slidably installed on the support frame. The adjusting part is driven to squeeze the long beam towards the side where the fixed part is located.

[0016] In the above technical solution, the pressing device provided by the present invention divides the sliding of the support block relative to the support frame into a first stroke and a second stroke. In the first stroke, the support block moves along the axial direction of the short beam, and in the second stroke, the support block moves along the axial direction of the long beam. A driving member is provided on the support frame, and the driving member directly pushes the support block to slide relative to the support frame and sequentially passes through the first stroke and the second stroke. The force direction of the slider always follows the guiding direction of the chute, thereby preventing the positioning block from shifting and ensuring that the joint angle can always be directly opposite to the ends of the short beam and the long beam during the extrusion process.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] As Figures 1-11 shown, a press-fitting device for side frame production and assembly provided by an embodiment of the present invention includes a support frame 1. Positioning components 2 for positioning corner joints are provided at the four corner positions of the support frame 1. The positioning component 2 includes a support block 21 slidably installed on the support frame 1. A positioning block 22 is fixedly connected to the support block 21. The support block 21 has a first stroke along the axial direction of the short beam and a second stroke along the axial direction of the long beam. A driving member is also provided on the support frame 1, and the driving member drives the support block 21 to sequentially pass through the first stroke and the second stroke to realize the connection of the corner joint with the short beam and the long beam.

[0023] Specifically, as Figure 1 and Figure 2As shown, the support frame 1 is the support structure of the pressing device, and its structure is in the shape of a cuboid. The support frame 1 includes a frame body 11 and a number of support platforms 12. A number of support platforms 12 are all fixed to the upper part of the frame body 11. A positioning assembly 2 is arranged on the support frame 1. There are four groups of the positioning assembly 2, and the four groups of the positioning assembly 2 are respectively arranged at the four corner positions of the upper surface of the support frame 1, so as to respectively position the four joints of the side frame; the positioning assembly 2 includes a support block 21 and a positioning block 22. The support block 21 is slidably installed on the corresponding support platform 12. A slider 23 is fixedly connected to the lower surface of the support block 21, and an L-shaped sliding groove for cooperating with the slider 23 is formed on the support platform 12. The two sides of the L-shaped sliding groove are respectively opened along the axial direction of the short beam and the axial direction of the long beam. In this way, the sliding of the support block 21 relative to the support platform 12 has a first stroke and a second stroke. In the first stroke, the support block 21 moves along the axial direction of the short beam, and in the second stroke, the support block 21 moves along the axial direction of the long beam. In addition, a driving member is also arranged on the support frame 1. The driving member drives the support block 21 to pass through the first stroke first and then the second stroke, so as to first squeeze the joint so that one end of it is inserted into the end of the short beam, and then squeeze the joint so that the other end of it is inserted into the end of the long beam; optionally, the driving member is two cylinders (not shown in the figure) fixed to the support platform 12. One cylinder is arranged along the axial direction of the short beam, and the other cylinder is arranged along the axial direction of the long beam. Preferably, the two cylinders are respectively arranged along the two sides of the sliding groove.

[0024] When assembling the side frame, the two groups of short beams are respectively placed on the support platforms 12 along the width direction of the support frame 1, the two groups of long beams are placed on the support platforms 12 along the length direction of the support frame 1, and the two ends of the short beams and the long beams are aligned with the joints. One cylinder extends and abuts against the support block 21, pushing the support block 21 to slide along one side of the sliding groove. This process corresponds to the first stroke of the support block 21. The joint moves synchronously with the support block 21 under the drive of the positioning block 22 and is inserted into the end of the short beam. At the end of the first stroke, the slider 23 slides to the corner position of the sliding groove. At this time, the support block 21 corresponds to the other cylinder. At this time, this group of cylinders extends and abuts against the support block 21, pushing the support block 21 to slide along the other side of the sliding groove. This process corresponds to the second stroke of the support block 21. The joint then moves synchronously with the support block 21 under the drive of the positioning block 22 and is inserted into the end of the long beam (in the second stroke, the short beam moves synchronously with its corresponding joint).

[0025] The pressing device provided by the embodiment of the present invention divides the sliding of the support block 21 relative to the support frame 1 into a first stroke and a second stroke. In the first stroke, the support block 21 moves along the axial direction of the short beam, and in the second stroke, the support block 21 moves along the axial direction of the long beam. A driving member is arranged on the support frame 1, and the driving member directly pushes the support block 21 to slide relative to the support frame 1 and sequentially passes through the first stroke and the second stroke. The force receiving direction of the slider 23 always follows the guiding direction of the chute, thereby preventing the positioning block 22 from shifting and ensuring that the joint angle can always be directly opposite to the ends of the short beam and the long beam during the extrusion process.

[0026] Further, support seats 13 are installed at the four corner positions of the support frame 1. The support block 21 is slidably connected to the support seats 13. Rotating rings 14 are rotatably installed on each support seat 13. The driving member includes a first cylinder 3 fixedly connected to each rotating ring 14. The first cylinder 3 is arranged along the radial direction of the corresponding rotating ring 14. The support block 21 coincides with the center line of its corresponding rotating ring 14 at the end of the first stroke.

[0027] Specifically, as Figures 1 to 4 shown, a support seat 13 is installed on the support frame 1. The support seat 13 is fixedly connected to the corresponding support platform 12. Different from the above embodiment, in this embodiment, the support block 21 is slidably connected to the support seat 13. The above L-shaped chute is also opened on the support seat 13. In addition, a rotating ring 14 is sleeved on the support seat 13. Preferably, the support seat 13 is a cylinder, and the rotating ring 14 is rotatably connected to the support seat 13. The driving member includes a first cylinder 3 fixedly connected to the rotating ring 14. The first cylinder 3 is arranged along the radial direction of the rotating ring 14. In this way, during the rotation of the rotating ring 14, the output end of the first cylinder 3 can always face the central axis of the support seat 13. And, in this embodiment, at the end of the first stroke of the support block 21, the center lines of the support block 21 and the rotating ring 14 coincide, that is, the corner position of the above L-shaped chute is on the central line of the support seat 13. In addition, a rotating cylinder 121 for driving the rotating ring 14 to rotate is provided on each support platform 12 where the rotating ring 14 is located. The rotating cylinder 121 is fixedly connected to the lower surface of the support platform 12. As Figure 4 shown, a swing arm 122 is fixedly connected to the rotating cylinder 121. The swing arm 122 penetrates through the support platform 12 and is fixedly connected to the lower surface of the rotating ring 14 so that the rotating cylinder 121 can drive the rotating ring 14 to rotate by 90°. An arc-shaped groove for the swing arm 122 to swing is opened through the upper and lower parts of the support platform 12. The initial positions of the first cylinders 3 are arranged along the axial direction of the corresponding short beam, as Figure 2As shown in the figure, during the assembly process of the side frame, the first cylinder 3 extends to drive the support block 21 to first pass through the first stroke, that is, the support block 21 slides along one side of the chute to the corner position of the chute. Then, the rotating ring 14 is driven by the rotating cylinder 121 to rotate 90°. The first cylinder 3 revolves 90° around the central axis of the rotating ring 14 under the drive of the rotating ring 14. At this time, the first cylinder 3 is arranged along the axial direction of the long beam. The first cylinder 3 continues to extend and drives the support block 21 to pass through the second stroke. In this way, the two extensions of the first cylinder 3 can respectively drive the support block 21 to move along the axial directions of the short beam and the long beam, so as to realize the connection of the corner joint with the short beam and the long beam.

[0028] Furthermore, the support block 21 is a cylinder, and a connecting piece is arranged on the support block 21. The output end of the first cylinder 3 is connected to the connecting piece, and the connecting piece can rotate around the central axis of the support block 21.

[0029] Specifically, in order to enable the first cylinder 3 to pull the support block 21 to slide reversely on the support seat 13 and restore the positioning block 22 to the initial position. In this embodiment, the support block 21 is in the shape of a cylinder. Therefore, when the support block 21 is driven to slide to the corner position of the chute on the support seat 13, the central axes of the rotating ring 14, the support seat 13, and the support block 21 will coincide. In addition, a connecting piece is arranged on the support block 21. Optionally, the connecting piece is a circular ring sleeved on the support block 21, and the circular ring can rotate relative to the support block 21. The output end of the first cylinder 3 is fixedly connected to the outer wall of the circular ring. When the support block 21 is driven by the first cylinder 3 to slide to the corner position of the chute and the rotating ring 14 is driven to rotate 90°, during the process, since the circular ring is rotatably installed on the support block 21, and the support block 21 and the circular ring will revolve around the central axis of the support block 21 under the drive of the first cylinder 3. Such a setting can directly connect the first cylinder 3 to the support block 21 without affecting the rotation of the first cylinder 3 with the rotating ring 14, so as to ensure that when the first cylinder 3 contracts, it can pull the support block 21 to slide reversely in the L-shaped chute on the support seat 13 and drive the positioning block 22 to restore to the initial position.

[0030] In another embodiment proposed by the present invention, the positioning block 22 includes a limiting block 221 for limiting the outside of the corner joint and a limiting rod 222 for limiting the inside of the corner joint. The cross-section of the limiting block 221 is L-shaped, the cross-section of the limiting rod 222 is rectangular, and the diagonals of the limiting block 221 and the limiting rod 222 coincide.

[0031] Specifically, in order to ensure that the corner joint cannot move relative to the support block 21 during the movement of the support block 21. In this embodiment, the positioning block 22 includes a limiting block 221 and a limiting rod 222, as Figure 6As shown, the cross-section of the positioning block 22 is L-shaped, while the cross-section of the limiting rod 222 is rectangular. The two enclose an L-shaped channel with openings at both ends, and the shape of this channel is adapted to that of the butt joint angle. During the process of restricting the butt joint angle, the limiting block 221 contacts the outer side wall of the butt joint angle, while the limiting rod 222 contacts the inner side wall of the butt joint angle, so as to position the butt joint angle from two directions and ensure that the butt joint angle cannot move relative to the support block 21.

[0032] Furthermore, the limiting rod 222 is rotatably connected to the support block 21 through a first rotating shaft 223. A receiving groove 211 for receiving the limiting rod 222 is provided on the support block 21. The limiting rod 222 is driven to rotate into the receiving groove 211 to cancel the restriction on the inner side of the butt joint angle.

[0033] Specifically, in the above embodiment, since it is necessary to ensure the positioning effect of the butt joint angle, both the limiting block 221 and the limiting rod 222 need to be in full contact with the butt joint angle. As a result, after the side frame is formed, it needs to move vertically to take out the butt joint angle from between the limiting block 221 and the limiting rod 222. However, the side frame is relatively large in size, making it difficult to control its vertical movement. That is, it is difficult to take out the four corner positions (four butt joint angles) of the side frame from the corresponding positioning blocks 22 after the side frame is formed. In this embodiment, the limiting rod 222 is rotatably installed on the support block 21. Optionally, a horizontally arranged first rotating shaft 223 is fixedly connected to the lower end of the limiting rod 222. Both ends of the first rotating shaft 223 are inside the support block 21, and both ends of the first rotating shaft 223 are rotatably connected to the support block 21. A receiving groove 211 is provided on the support block 21. When the limiting rod 222 is driven to rotate around the central axis of the first rotating shaft 223, it can rotate into the receiving groove 211, thus no longer restricting the inner side wall of the butt joint angle. As a result, when the first cylinder 3 contracts, it can pull the support block 21 to move in the reverse direction, further eliminating the restriction of the limiting block 221 on the outer side wall of the butt joint angle, so as to facilitate the removal of the formed side frame. Optionally, a motor is provided inside the support block 21, and the output end of the motor is directly connected to one end of the first rotating shaft 223. The first rotating shaft 223 can be driven to rotate by the motor.

[0034] Preferably, the cross-section of the limiting rod 222 is square, a diagonal line of the cross-section of the limiting rod 222 coincides with the diagonal line of the limiting block 221, and the rotation axis of the limiting rod 222 is parallel to the other diagonal line of its cross-section.

[0035] Specifically, to ensure that the limiting rod 222 does not rub against the inner wall of the joint angle or the outer wall of the long beam when driven to rotate, in this embodiment, the cross-section of the limiting rod 222 is square. Among the two diagonals of this square, one coincides with the diagonal of the limiting block 221, and the above-mentioned first rotating shaft 223 is arranged parallel to the other diagonal. With this arrangement, when the limiting rod 222 is driven to rotate into the receiving groove 211, it can directly move away from the inner wall of the joint angle, thus avoiding unnecessary friction.

[0036] In yet another embodiment provided by the present invention, a transmission member 4 is disposed inside the support block 21. When the first cylinder 3 extends, it first drives the limiting rod 222 to rotate outwards from the receiving groove 211 through the transmission member 4. When the first cylinder 3 contracts, it first drives the limiting rod 222 to rotate into the receiving groove 211 through the transmission member 4.

[0037] Furthermore, the transmission member 4 includes a second rotating shaft 41 rotatably installed in the support seat 13. The central axes of the second rotating shaft 41 and the support block 21 coincide. A first bevel gear 42 is fixedly connected to the upper end of the second rotating shaft 41. A second bevel gear 43 is sleeved outside the first rotating shaft 223. The first bevel gear 42 and the second bevel gear 43 are meshed with each other. A spur gear 44 is sleeved in the middle of the second rotating shaft 41. The output end of the first cylinder 3 is fixedly connected to a rack 45. The rack 45 and the spur gear 44 are meshed with each other.

[0038] Specifically, in the above embodiment, the limiting rod 222 is driven to rotate by a motor disposed in the support seat 13. However, since the support block 21 needs to slide relative to the support seat 13, it is not convenient to arrange the motor. In this embodiment, a transmission member 4 is disposed inside the support block 21. The transmission member 4 includes a second rotating shaft 41 rotatably installed in the support seat 13, as Figure 5 Figure 8 and Figure 9As shown, the lower end of the second rotating shaft 41 is rotatably connected to the inner wall of the support base 13, and the upper end of the second rotating shaft 41 is fixedly connected with a first bevel gear 42. One end of the first rotating shaft 223 is fixedly connected with a second bevel gear 43, and the first bevel gear 42 and the second bevel gear 43 are meshed with each other, so that when the second rotating shaft 41 is driven to rotate, it can drive the first rotating shaft 223 to rotate; in addition, a spur gear 44 is sleeved on the middle part of the second rotating shaft 41, and the output end of the first air cylinder 3 is fixedly connected with a rack 45. The spur gear 44 and the rack 45 are meshed with each other. To ensure that the rack 45 does not separate from the spur gear 44 during the process of the rotating ring 14 driving the first air cylinder 3 to rotate, the central axis of the second rotating shaft 41 coincides with the central axis of the support block 21, that is, the central axis of the second rotating shaft 41 also coincides with the central axis of the rotating ring 14. In this way, during the process of the first air cylinder 3 rotating with the rotating ring 14, the rack 45 can revolve around the central axis of the second rotating shaft 41 and remain meshed with the spur gear 44, thereby avoiding the separation of the rack 45 from the spur gear 44 during the process of the support block 21 being pulled and reset; in addition, a sector-shaped groove 212 is also formed on the support block 21 to make space for the rack 45 to revolve around the central axis of the second rotating shaft 41.

[0039] With such a setting, the first air cylinder 3 has three stages when extending: In the first stage, when the first air cylinder 3 extends, it drives the rack 45 to move towards the inside of the support block 21. The rack 45 drives the second rotating shaft 41 to rotate through the spur gear 44. The second rotating shaft 41 drives the limiting rod 222 to rotate outwards from the storage groove 211 through the cooperation of the first bevel gear 42 and the second bevel gear 43. During this process, if when the corner joint is placed, its outer side wall is not completely attached to the limiting block 221, the limiting rod 222 can also finely adjust the corner joint during the rotation process. By squeezing the inner side wall of the corner joint by the limiting rod 222, the outer side wall of the corner joint is pushed to abut against the limiting block 221. Obviously, to ensure that the support block 21 does not slide on the support base 13 during this stage, the friction between the support block 21 and the support base 13 can be increased; In the second stage, the first air cylinder 3 continues to extend, and the output end of the first air cylinder 3 abuts against the outer wall of the support block 21 and pushes the support block 21 to slide along the restricted direction of the chute. This process corresponds to the first stroke of the support block 21.

[0040] When the support block 21 slides to the corner position of the chute, it drives the rotating ring 14 to rotate 90°, adjusts the extension direction of the first air cylinder 3 along the axial direction of the long beam. At this time, the first air cylinder 3 extends again. This is the third stage of the extension of the first air cylinder 3, and the third stage corresponds to the second stroke of the support block 21.

[0041] Similarly, when the first cylinder 3 contracts, it first pulls the rack 45, causing the rack 45 to drive the second rotating shaft 41 to rotate in the reverse direction. The second rotating shaft 41, through the cooperation of the first bevel gear 42 and the second bevel gear 43, drives the limiting rod 222 to rotate in the reverse direction into the receiving groove 211, canceling the restriction of the limiting rod 222 on the inner side wall of the docking angle. When the limiting rod 222 contracts to the point where it cannot rotate further in the receiving groove 211, the second rotating shaft 41 will be stuck. At this time, since the rack 45 is still engaged with the spur gear 44, the first cylinder 3 will pull the spur gear 44 to move through the rack 45, and the spur gear 44 will drive the entire support block 21 to slide reversely along the above-mentioned chute. The cooperation between the rack 45 and the spur gear 44 is equivalent to the connecting member in the above embodiment, thereby further canceling the restriction of the limiting block 221 on the outer side wall of the docking angle, facilitating the staff to take the formed side frame.

[0042] In this embodiment, through the transmission member 4 provided in the support block 21, the first cylinder 3 can drive the limiting rod 222 to rotate during the initial stage of elongation, that is, the first stage, to finely adjust the position of the docking angle, ensuring that the outer side wall of the docking angle can be abutted against the limiting block 221. After the side frame is formed, the first cylinder 3 can drive the limiting rod 222 to rotate in the reverse direction during the initial stage of contraction, canceling the restriction of the limiting rod 222 on the inner side wall of the docking angle, and can also pull the support block 21 to move reversely along the chute through the transmission member 4, further canceling the restriction of the limiting block 221 on the outer side wall of the docking angle.

[0043] In another embodiment proposed by the present invention, a support plate 5 is installed on the support block 21 along the length direction of the short beam. One side of the upper surface of the support plate 5 is fixedly connected with a baffle 51, and the other side of the upper surface of the support plate 5 is rotatably installed with a stop rod 52. A torsion spring capable of maintaining the stop rod 52 in a vertical state is provided at the hinge position of the stop rod 52 and the support plate 5.

[0044] Specifically, to ensure that the short beam can move together with the docking angle after connecting the docking angle and the short beam, in this embodiment, a support plate 5 is fixedly connected to one side of the upper surface of the support plate 5, and a stop rod 52 is rotatably installed on the other side of the upper surface of the support plate 5. The stop rod 52 is rotatably connected to the support plate 5 through a rotating shaft, and a torsion spring is sleeved on the rotating shaft. The torsion spring maintains the stop rod 52 in a vertical state to ensure that the short beam is limited, as Figure 2 shown, a baffle 51 is fixedly connected to one side of the support plate 5. Figure 2 On the support plate 5 on the left side of the support frame 1 in Figure 2 the baffle 51 is installed on the left side of the support plate 5, and the stop rod 52 is rotatably installed on

The extrusion assembly 6 includes a fixed part fixedly connected to the support frame 1 and an adjustment part slidably mounted on the support frame 1. The adjustment part is driven to extrude the long beam towards the side where the fixed part is located.

[0046] Specifically, as Figure 2 shown, to ensure that the long beam can be accurately restricted to the set position after being placed, so that the joint angle can be directly opposite to the end of the long beam when the support block 21 is in the second stroke. In this embodiment, an extrusion assembly 6 for positioning the long beam is further provided on the support frame 1. The extrusion assembly 6 includes a fixed part and an adjustment part. The fixed part includes a fixing block 61 with a cross-section approximately in the shape of a C. The fixing block 61 is fixedly installed on the support platform 12 provided at the corresponding position on the frame body 11. Two groups of rollers 611 are rotatably installed on the fixing block 61. Both groups of rollers 611 are vertically arranged. The adjustment part includes an adjustment block 62 with a cross-section approximately in the shape of a C. The adjustment block 62 is slidably connected to the corresponding support platform 12, and the adjustment block 62 slides along the width direction of the frame body 11, that is, Figure 2 the vertical direction in the view. A second cylinder 63 for driving the adjustment block 62 to slide is further provided on the support platform 12. The second cylinder 63 is fixedly connected to the corresponding support platform 12, and the second cylinder 63 is arranged along the width direction of the frame body 11; Figure 2 In, three groups of extrusion assemblies 6 are provided on both long sides of the frame body 11. The extrusion assemblies 6 correspond to the two ends and the middle of the long beam respectively. Each adjustment block 62 is driven to simultaneously push the long beam from the two ends and the middle of the long beam towards the position where the fixed part is located, so as to realize the precise positioning of the long beam.
