Description

Technical Field

[0001] This utility model relates to the field of frame assembly technology, and in particular to a door and window frame clamping mechanism that prevents deformation. Background Technology

[0002] During the assembly of furniture doors, windows, and other frame components, the horizontal and vertical bars of the door and window frames need to be spliced ​​according to the design drawings and then fixed with corner brackets or connectors to ensure that the connection is firm. When fixing, the frame needs to be clamped to ensure that after the adhesive has cured, each component of the frame is in the preset position.

[0003] In the prior art, such as the patent with announcement number CN209408313U, a clamping mechanism and a high-frequency frame assembly machine are disclosed, including a first clamping assembly and a second clamping assembly. The first clamping assembly includes at least three sets of first clamping blocks and first clamping drive members. The first clamping drive members and the first clamping blocks are connected one by one. The first clamping blocks are used to abut against the corners of the frame under the drive of the corresponding first clamping drive members to jointly clamp the frame. The second clamping assembly includes second clamping blocks and second clamping drive members that are connected to each other.

[0004] The above structure uses multiple clamping blocks to hold the frame at the corners. However, during the assembly of the entire frame, when the four corners are clamped at the same time, the corners are prone to deformation when they come into contact after the driving pressure is applied. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a deformation-resistant door and window frame clamping mechanism to solve the problem that deformation is easily caused when the four corners are clamped at the same time during the assembly process of the entire frame and pressure is applied to the drive.

[0006] Based on the above objectives, this utility model provides a door and window frame clamping mechanism to prevent deformation, including a workbench and multiple sets of transmission rollers rotatably connected inside the workbench. Multiple sets of side plates are fixedly installed on both sides of the workbench. Clamping component one and clamping component two are provided on the side plates on both sides of the workbench. The clamping component one and clamping component two are arranged in a mirror symmetrical manner.

[0007] Both clamping component one and clamping component two are equipped with two sets of clamping structures inside. The two sets of clamping structures are arranged diagonally opposite each other. The clamping structures are used to clamp the horizontal and vertical bars inside the door and window frame. First, the horizontal and vertical bars are assembled into an L-shaped door and window frame using clamping component one. Then, the two L-shaped door and window frames are assembled into a whole using clamping component two.

[0008] Preferably, the clamping structure includes a rotating rod passing through the side plate, a movable sleeve sleeved around the rotating rod, and a spiral column fixedly installed at the top of the rotating rod. A knob is provided at the top of the spiral column through the top of the movable sleeve. A right-angle rod is fixedly installed around the movable sleeve. A support rod is fixedly installed at one end of the right-angle rod. A side rod is hinged to one end of the support rod. Clamping blocks for clamping the door and window frame are fixedly installed on adjacent sides of the side rod and the support rod.

[0009] An electric telescopic rod is installed inside the support rod, and an elastic plate is fixedly installed on one side of the side rod. The output end of the electric telescopic rod is fixedly connected to one end of the elastic plate.

[0010] Preferably, a servo motor is fixedly installed at the bottom of the side plate, and the output end of the servo motor is fixedly connected to the bottom of the rotating rod.

[0011] Preferably, the top of the rotating rod is a trapezoidal platform structure, and the interior of the movable sleeve has an inclined groove corresponding to the top of the rotating rod.

[0012] Preferably, a locking block is fixedly installed on the outside of the rotating rod, and a slot is opened inside the inclined groove to accommodate the locking block sliding up and down.

[0013] Preferably, the knob has a spiral portion inside that corresponds to the spiral post.

[0014] Preferably, the clamping structure is distributed in at least four groups, and the clamping structure is distributed in a wavy pattern on both sides of the worktable.

[0015] The beneficial effects of this utility model are:

[0016] The horizontal and vertical bars of the door and window frame are spliced ​​together according to the design drawings. After splicing, they are initially connected and placed on the conveyor rollers in the workbench. When the frame is conveyed to the clamping part, the clamping structure on both sides starts to work. The clamping structure clamps the corners of the horizontal and vertical bars of one group of door and window frames. At this time, the two L-shaped door and window frames are initially completed.

[0017] When the two L-shaped door and window frames continue to move to the second clamping position, the internal clamping structure fits the contact ends of the two L-shaped door and window frames together, and then corner brackets or connectors are used to fix them to ensure that the connection is firm, thereby completing the assembly of the entire frame and preventing deformation caused by clamping the four corners at the same time.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a deformation-resistant door and window frame clamping mechanism includes a workbench 1 and multiple sets of transmission rollers 2 rotatably connected inside the workbench 1. Multiple sets of side plates 6 are fixedly installed on both sides of the workbench 1. Clamping element 1 3 and clamping element 2 4 are provided on the side plates 6 on both sides of the workbench 1. Clamping element 1 3 and clamping element 2 4 are arranged in a mirror symmetrical manner.

[0026] Both clamping component 3 and clamping component 4 have two sets of clamping structures 5 inside. The two sets of clamping structures 5 are arranged diagonally opposite each other. The clamping structures 5 are used to clamp the horizontal and vertical bars in the door and window frame. First, the horizontal and vertical bars are assembled into an L-shaped door and window frame by clamping component 3, and then the two L-shaped door and window frames are assembled into a whole by clamping component 4.

[0027] In this embodiment, the horizontal and vertical bars of the door and window frame are first spliced ​​together according to the design drawings. After splicing, they are initially connected and placed on the transmission roller 2 in the workbench 1. When the transmission reaches the clamping part 3, the clamping structure 5 on the side plates 6 on both sides starts to work. The clamping structure 5 clamps the corners of one group of horizontal and vertical bars of the door and window frame. At this time, the two L-shaped door and window frames at opposite corners are initially completed.

[0028] When the two L-shaped door and window frames continue to move to the position of clamping part 4, the internal clamping structure 5 fits the contact ends of the two L-shaped door and window frames together, and then corner brackets or connectors are used to fix them to ensure that the connection is firm, thereby completing the assembly of the entire frame and preventing deformation caused by clamping the four corners at the same time.

[0029] As one implementation method, such as Figure 3 As shown, the clamping structure 5 includes a rotating rod 7 that passes through the side plate 6. A movable sleeve 8 is sleeved on the outside of the rotating rod 7, and a spiral column 15 is fixedly installed at the top of the rotating rod 7. A knob 16 is provided at the top of the spiral column 15 that passes through the top of the movable sleeve 8. A right-angle rod 9 is fixedly installed on the outside of the movable sleeve 8. A support rod 10 is fixedly installed at one end of the right-angle rod 9. A side rod 11 is hinged to one end of the support rod 10. Clamping blocks 12 for clamping the door and window frame are fixedly installed on the adjacent sides of the side rod 11 and the support rod 10.

[0030] An electric telescopic rod 14 is installed inside the support rod 10, and an elastic plate 13 is fixedly installed on one side of the side rod 11. The output end of the electric telescopic rod 14 is fixedly connected to one end of the elastic plate 13.

[0031] In this embodiment, the servo motor 19 inside the clamping structure 5 drives the rotating rod 7 and the movable sleeve 8 to rotate, and the support rod 10 starts to rotate at the same time. The electric telescopic rod 14 inside the support rod 10 pulls the side rod 11 at one end of the elastic plate 13. After rotating 90°, the side rod 11 and the support rod 10 are at a right angle. Due to the setting of the right angle rod 9, the side rod 11 and the support rod 10 are respectively attached to the horizontal and vertical bars of the door and window frame. Then, the clamping block 12 clamps them, so that the corners of the horizontal and vertical bars of the door and window frame are clamped.

[0032] As one implementation method, such as Figure 3 and Figure 4 As shown, a servo motor 19 is fixedly installed at the bottom of the side plate 6, and the output end of the servo motor 19 is fixedly connected to the bottom of the rotating rod 7.

[0033] In this embodiment, the servo motor 19 drives the rotating rod 7 to rotate, and the electric telescopic rod 14 pulls the side rod 11 of the elastic plate 13, so that after rotating 90°, the side rod 11 and the support rod 10 are at right angles. Due to the setting of the right angle rod 9, the side rod 11 and the support rod 10 are respectively in contact with the horizontal and vertical bars of the door and window frame.

[0034] As one implementation method, such as Figure 4 As shown, the top of the rotating rod 7 is a trapezoidal platform structure, and the interior of the movable sleeve 8 has an inclined groove 17 corresponding to the top of the rotating rod 7.

[0035] In this embodiment, as the movable sleeve 8 moves downward, and due to the setting of the inclined groove 17, the movable sleeve 8 gradually contacts the trapezoidal platform, thereby enhancing the stability of the entire clamping structure 5.

[0036] As one implementation method, such as Figure 4 As shown, a locking block 18 is fixedly installed on the outside of the rotating rod 7, and a slot is opened inside the inclined groove 17 to accommodate the locking block 18 sliding up and down.

[0037] In this embodiment, by utilizing the arrangement of the card block 18 and the card slot, when the servo motor 19 drives the rotating rod 7 to rotate, the movable sleeve 8 rotates accordingly.

[0038] As one implementation method, such as Figure 4 As shown, the knob 16 has a spiral part inside that corresponds to the spiral post 15.

[0039] In this embodiment, the knob 16 is driven to rotate by an external electric device. Since the knob 16 has a spiral part inside, when the knob 16 rotates, it rotates outside the spiral column 15, thereby pressing the movable sleeve 8 to move downward. Furthermore, due to the setting of the inclined groove 17, the movable sleeve 8 gradually contacts until the knob 16 is locked, thereby strengthening the stability of the clamping structure 5 and improving assembly efficiency and accuracy.

[0040] As one implementation method, such as Figure 1 , Figure 2 As shown, there are at least four sets of clamping structures 5, and the clamping structures 5 are distributed in a wavy pattern on both sides of the worktable 1.

[0041] In this embodiment, multiple sets of clamping structures 5 distributed in a wavy pattern can ensure a firm connection at each node of the door and window frame, thus completing the assembly of the entire frame.

[0042] Working principle: In use, the horizontal and vertical bars of the door and window frame are first spliced ​​according to the design drawings. After splicing, they are initially connected and placed on the transmission roller 2 in the workbench 1. When the transmission reaches the clamping part 3, the clamping structure 5 on the side plates 6 on both sides starts to work. The servo motor 19 drives the rotating rod 7 and the movable sleeve 8 to rotate. The support rod 10 starts to rotate at the same time. The electric telescopic rod 14 in the support rod 10 pulls the side rod 11 at one end of the elastic plate 13. After rotating 90°, the side rod 11 and the support rod 10 are at a right angle. Due to the setting of the right angle rod 9, the side rod 11 and the support rod 10 are respectively attached to the horizontal and vertical bars of the door and window frame. Then, they are clamped by the clamping block 12 to clamp the corners of the horizontal and vertical bars of the door and window frame.

[0043] After clamping the frame, rotate the knob 16 to rotate the spiral column 15 outside, thereby moving downward and pressing the movable sleeve 8 downward. The inclined groove 17 inside the movable sleeve 8 contacts the trapezoidal platform of the rotating rod 7 downward, thereby making the side rod 11 and support rod 10 on the movable sleeve 8 more stable. After the movable sleeve 8 is tightened, use corner brackets or connectors to fix it to ensure that the adhesive cures. At this time, the two L-shaped door and window frames are initially completed.

[0044] When the two L-shaped door and window frames continue to move to the position of clamping piece 24, the side rod 11 and support rod 10 are attached to the contact ends of the two L-shaped door and window frames, and then clamped by clamping block 12. After clamping the frame, corner brackets or connectors are used to fix it to ensure that the connection is firm, thereby completing the assembly of the entire frame and preventing deformation caused by clamping the four corners at the same time.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
