Description

Technical Field

[0001] The utility model relates to the technical field of door and window processing, in particular to a pressing device for door and window processing. Background Technique

[0002] In order to avoid the movement of the door and window frame, reduce the processing safety hazards and control the processing errors of the door and window, so as to improve the processing quality of the product, simplify the operation process and meet the special processing requirements, etc., during the processing of the door and window, a pressing device is needed to limit the position of the door and window frame. Most of the existing door and window frame pressing devices will set four positioning blocks on the upper side of the operating table. Through the clamping effect between the four positioning blocks and the periphery of the door and window frame, the door and window frame can be pressed and positioned. However, for this kind of pressing device, the movement trajectories of the four positioning blocks on its upper side are relatively fixed, which leads to that when the aspect ratio of the shape of the door and window frame changes, it will be difficult for this kind of pressing device to continue to position the door and window frame, which obviously has relatively large defects. For this reason, we have proposed a pressing device for door and window processing. Content of the Utility Model

[0003] The purpose of the utility model is to provide a pressing device for door and window processing to solve the problems put forward in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A pressing device for door and window processing, including an operating table, a first movable plate and a second movable plate are rotatably installed at the upper end of the operating table. Limiting rotating seats are respectively and fixedly installed on both sides of the upper ends of the first movable plate and the second movable plate. An movable seat is arranged between the two limiting rotating seats. Connecting seats are rotatably installed at the upper ends of the four movable seats. A plug board inserted into the adjacent connecting seat on one side is fixedly installed on one side of the connecting seat. The four plug boards are symmetrically distributed around the center. A limiting clamping board is fixedly installed at the upper end of the connecting seat. The adjacent limiting clamping boards are symmetrically arranged with each other. A pressing cavity is formed by the clearance fit of the four limiting clamping boards. A first threaded rod threadedly connected with the movable seat is rotatably installed between the two limiting rotating seats. A gear is fixedly installed at the inner end of the first threaded rod. A toothed disc meshed with each gear is rotatably installed at the upper end of the operating table.

[0005] Preferably, a limiting rotating shaft is fixedly installed at the upper end of the operating table. A first rotating plate is fixedly installed in the middle of the first movable plate.

[0006] Preferably, an insertion cavity is formed on one side of the connecting seat. The plug board is inserted and installed in the insertion cavity. A limiting rotating hole is formed at the upper end of the movable seat. A limiting rotating block rotatably connected with the limiting rotating hole is fixedly installed at the lower end of the connecting seat.

[0007] Preferably, an annular positioning tooth groove is formed on the periphery of the operating table. Connecting plates are fixedly installed on both sides of the lower ends of the first movable plate and the second movable plate. Positioning tooth blocks inserted into the annular positioning tooth groove are arranged inside the connecting plates.

[0008] Preferably, threaded holes are formed inside the positioning tooth blocks, and second threaded rods threadedly connected to the threaded holes are rotatably installed on the connecting plates.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

And through the meshing connection between the gear disc and the gear and the threaded connection between the first threaded rod and the movable seat, the first threaded rod rotating on one side can drive each connecting seat to contract or expand.

[0011] For the door and window processing pressing device, through the plug-in connection between the insertion plate and the socket, the mutually limiting clamping plates are symmetrically arranged. When the first movable plate and the second movable plate rotate, it can ensure that the adjacent two-sided limiting clamping plates are symmetrically arranged, ensuring the pressing effect of the limiting clamping plates on the door and window frame.

[0012] For the door and window processing pressing device, through the threaded connection between the second threaded rod and the threaded hole, the position of the positioning tooth block can be adjusted.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-5 , the present invention provides a technical solution: a door and window processing pressing device, including an operating table 1, a first movable plate 121 and a second movable plate 131 are rotatably installed at the upper end of the operating table 1, limit rotating seats 2 are fixedly installed on both sides of the upper ends of the first movable plate 121 and the second movable plate 131, a movable seat 14 is arranged between the two limit rotating seats 2, a connecting seat 15 is rotatably installed at the upper ends of the four movable seats 14, an insertion plate 16 inserted into the adjacent connecting seat 15 on one side is fixedly installed on one side of the connecting seat 15, the four insertion plates 16 are symmetrically distributed around the center, a limit clamping plate 151 is fixedly installed at the upper end of the connecting seat 15, the adjacent limit clamping plates 151 are symmetrically arranged with each other, and a pressing cavity 152 is formed by the clearance fit of the four limit clamping plates 151. A first threaded rod 21 threadedly connected to the movable seat 14 is rotatably installed between the two limit rotating seats 2, a gear 23 is fixedly installed at the inner end of the first threaded rod 21, and a tooth disc 22 meshed with each gear 23 is rotatably installed at the upper end of the operating table 1.

[0024] Working principle: Before installing the door and window frame, according to the aspect ratio of the frame shape, the first movable plate 121 and the second movable plate 131 can be rotated at the upper end of the operating table 1 to adjust the positions of the respective connecting seats 15. For the moving connecting seat 15, through the plug-in connection between the connecting seat 15 and the insertion plate 16 on the adjacent side, it can always ensure that the adjacent limit clamping plates 151 are symmetric with each other, achieving the effect of adjusting the pressing cavity 152 so that the aspect ratio of the pressing cavity 152 is equal to that of the door and window frame;

[0025] When installing the door and window frame, rotate the first threaded rod 21 on one side. Through the meshing connection between the toothed disc 22 and each gear 23, the first threaded rod 21 rotating on one side can drive the rest of the first threaded rods 21 to rotate with it. Since the movable seat 14 is in contact with the lower ends of the first movable plate 121 and the second movable plate 131, the movement direction of the movable seat 14 can be restricted. Then, the rotating first threaded rod 21 can drive the movable seat 14 to contract inward, and the door and window frame can be installed in the pressing cavity 152. Rotate the first threaded rod 21 again to make each limiting clamping plate 151 be clamped with the periphery of the door and window frame, achieving the effect of pressing the door and window frame.

[0026] As a further description of the above technical solution: A limiting rotating shaft 11 is fixedly installed at the upper end of the operating table 1. A first rotating plate 12 is fixedly installed in the middle of the first movable plate 121, and a second rotating plate 13 is fixedly installed in the middle of the second movable plate 131. The toothed disc 22, the first movable plate 121, and the second movable plate 131 are rotatably installed around the limiting rotating shaft 11; A plug cavity 161 is formed on one side of the connecting seat 15, the plug plate 16 is inserted and installed in the plug cavity 161, a limiting rotating hole 171 is formed at the upper end of the movable seat 14, and a limiting rotating block 17 rotatably connected to the limiting rotating hole 171 is fixedly installed at the lower end of the connecting seat 15.

[0027] Specifically, setting the limiting rotating shaft 11 can restrict the movement directions of the toothed disc 22, the first movable plate 121, and the second movable plate 131 at the upper end of the operating table 1;

[0028] Through the plug-in connection between the plug cavity 161 and the connecting seat 15, and through the plug-in connection between the limiting rotating hole 171 and the limiting rotating block 17, when the first rotating plate 12 and the second movable plate 131 rotate to drive the connecting seat 15 to rotate, it can ensure that each connecting seat 15 is always symmetrically arranged.

[0029] As a further description of the above technical solution: An annular positioning tooth groove 3 is formed on the periphery of the operating table 1. Positioning tooth blocks 32 are fixedly installed on both sides of the lower ends of the first movable plate 121 and the second movable plate 131. A positioning tooth block 32 is arranged inside the connecting plate 31 and is inserted into the annular positioning tooth groove 3; A threaded hole 33 is formed inside the positioning tooth block 32, and a second threaded rod 34 threadedly connected to the threaded hole 33 is rotatably installed on the connecting plate 31.

[0030] Specifically, after rotating the first movable plate 121 and the second movable plate 131 at the upper end of the operation table 1, the second threaded rod 34 can be rotated at the outer end of the connecting plate 31. Since the upper and lower sides of the positioning tooth block 32 are in mutual contact with the upper and lower sides of the inner cavity of the annular positioning tooth groove 3, the movement direction of the positioning tooth block 32 can be restricted, so that the rotating second threaded rod 34 can drive the positioning tooth block 32 to move inward to be inserted into the annular positioning tooth groove 3 through the threaded connection between it and the threaded hole 33, achieving the effect of positioning the first movable plate 121 and the second movable plate 131 at the upper end of the operation table 1.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
