Description

Technical Field

[0001] This utility model relates to the field of machine tools, and more specifically to an automatic door structure for use in areas with limited installation space. Background Technology

[0002] Currently, automatic doors are widely used in machining centers, including front automatic doors, side automatic doors, and top automatic doors. These automatic doors are basically driven by standard cylinders to open and close the doors. The total length of the cylinder after extension is more than twice the door opening size. If the opening size of the automatic door is similar to the available installation space, it is not suitable to use a standard cylinder.

[0003] Therefore, there is a need to develop an automatic door structure that can meet the opening size requirements of automatic doors and still allow for installation even when the available installation space is limited. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic door structure for installation in areas with limited space, solving the problems of existing automatic door structures that use linear modules to drive the opening and closing of the automatic door, resulting in high costs; and the inability to be used in installation environments where the available space size and the automatic door opening size are similar.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: an automatic door structure for installation in limited space includes an automatic door opening frame, a set of mounting supports are respectively arranged on the front and rear sides of the automatic door opening frame, and a magnetically coupled rodless cylinder is arranged on each set of mounting supports; a slider that can move along the thin-walled cylinder is arranged on the magnetic ring sleeve of each of the two magnetically coupled rodless cylinders; a guide bridge is erected above the automatic door opening frame, and the two ends of the guide bridge are respectively arranged on a slider, and the guide bridge can move with the two sliders; a bellows cover is arranged inside the opening of the automatic door opening frame, the right end of the bellows cover is fixedly arranged on the right end of the automatic door opening frame; the left end of the bellows cover is fixedly arranged on the guide bridge, and the bellows cover can be opened and closed as the guide bridge moves.

[0006] Furthermore, the guide bridge includes a front connecting plate and a rear connecting plate respectively disposed on the front and rear sliders of the automatic door opening frame, and a fixing plate disposed between the front connecting plate and the rear connecting plate. The bottom of the fixing plate is provided with a mounting plate, and the left end of the bellows cover is disposed on the mounting plate. The front connecting plate and the rear connecting plate are provided with a set of mounting holes that are adapted to the fixing plate along their length direction.

[0007] Furthermore, the automatic door opening frame is a square frame, which includes a front guide groove and a rear guide groove with an inner width and a accordion cover, and a left positioning plate and a right positioning plate connected between the front guide groove and the rear guide groove. The left positioning plate and the right positioning plate are L-shaped. The right fixed end of the accordion cover is fixedly set on the right positioning plate. The front and rear ends of the accordion cover can move within the grooves of the front guide groove and the rear guide groove.

[0008] Furthermore, it also includes a set of air pipes and a three-way connector. The left ends of the two magnetically coupled rodless cylinders are connected by air pipes and a three-way connector, and the right ends are connected by air pipes and a three-way connector.

[0009] Furthermore, the two magnetically coupled rodless cylinders are identical in model, specifications, and dimensions, and are arranged in parallel on the front and rear sides of the automatic door opening frame.

[0010] The beneficial effects of this invention are as follows: By using a magnetically coupled rodless cylinder, a guide bridge, and a bellows cover within the automatic door opening frame, the bellows cover can be expanded and retracted, improving space utilization. Simultaneously, the magnetically coupled rodless cylinder reduces installation space occupancy while maintaining the automatic door opening size, enabling installation and functionality in environments where the available installation space and automatic door opening size are similar. Furthermore, this structure effectively reduces the high costs associated with using linear modules.

[0011] By setting a guide bridge, and the guide bridge adopting a split structure of front connecting plate, rear connecting plate, fixed plate and mounting plate, and the front connecting plate and rear connecting plate having a set of assembly holes that match the fixed plate along their length, not only can the synchronous movement of the upper slider of the two magnetically coupled rodless cylinders be realized, but the length of the guide bridge can also be flexibly adjusted as needed. At the same time, the installation of the magnetically coupled rodless cylinder and the guide bridge is more flexible and convenient.

[0012] The automatic door opening frame is equipped with magnetically coupled rodless cylinders on both the front and rear sides, which makes the force on the guide bridge more even during movement, and makes the opening and closing of the packaging bellows cover more stable and reliable.

[0013] The left and right guide grooves can play a certain role in limiting and guiding the bellows cover during its opening and closing, while also improving the sealing effect on both sides.

[0014] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0020] Examples, such as Figures 1 to 4 The diagram illustrates an automatic door structure for installation in confined spaces, comprising an automatic door opening frame. A set of mounting supports 1 is provided on both the front and rear sides of the automatic door opening frame, and each set of mounting supports is equipped with a magnetically coupled rodless cylinder 2. Each magnetically coupled rodless cylinder 2 has a slider 3 mounted on its magnetic ring sleeve, which can move along the thin-walled cylinder barrel. A guide bridge is mounted above the automatic door opening frame, with each end of the guide bridge mounted on a slider 3, allowing the guide bridge to move with the two sliders 3. A bellows cover 4 is installed inside the opening of the automatic door opening frame, with its right end fixed to the right end of the automatic door opening frame and its left end fixed to the guide bridge. The bellows cover 4 can expand and retract as the guide bridge moves. Since the magnetically coupled rodless cylinder 2 itself is not an innovation of this solution, nor is its specific working principle, the innovation of this solution lies not in the specific structure of the magnetically coupled rodless cylinder 2 or how it achieves its function; therefore, it will not be further described here. Those skilled in the art can easily implement this by setting up a control system, corresponding components, and corresponding electrical connections, based on existing technology and common knowledge in the field. The left end of the bellows cover 4 is detachably mounted on the guide bridge.

[0021] The guide bridge includes a front connecting plate 5 and a rear connecting plate 6 respectively installed on the sliders 3 on the front and rear sides of the automatic door opening frame, and a fixing plate 7 installed between the front connecting plate 5 and the rear connecting plate 6. The bottom of the fixing plate 7 is provided with a mounting plate 8, and the left end of the bellows cover 4 is installed on the mounting plate 8. The front connecting plate and the rear connecting plate are provided with a set of mounting holes that are compatible with the fixing plate along their length direction. The left end of the bellows cover 4 is installed in a detachable manner.

[0022] Meanwhile, the guide bridge adopts a split structure of front connecting plate 5, rear connecting plate 6, and fixing plate 7, which allows for more flexible adjustment of the guide bridge length and facilitates adaptation to the size of automatic doors. Depending on the required length, different lengths of fixing plate 7 can be selected for replacement to meet the needs; or the overall length can be adjusted by assembling the two ends of fixing plate 7 onto the mounting holes at different positions on the front connecting plate 5 and the rear connecting plate 6.

[0023] The magnetically coupled rodless cylinder 2 drives the slider 3 to move, which in turn drives the guide bridge connected to the slider 3 to move. The movement of the guide bridge causes the left end of the bellows cover 4, which is connected to it, to move as the right end of the bellows cover 4 is fixed to the automatic door opening frame. The left end of the bellows cover 4 moves left and right with the guide bridge, thus realizing the opening and closing of the bellows cover and the automatic door.

[0024] The automatic door opening frame is a square frame, which includes a front guide groove 11 and a rear guide groove 12 that fit the accordion cover 4, and a left positioning plate 9 and a right positioning plate connected between the front guide groove 11 and the rear guide groove 12. The left positioning plate 9 and the right positioning plate are L-shaped. The right fixed end of the accordion cover 4 is fixedly set on the right positioning plate. The front and rear ends of the accordion cover 4 can move within the grooves of the front guide groove 11 and the rear guide groove 12.

[0025] This automatic door structure, designed for installation in space-constrained environments, also includes a set of air pipes 13 and a three-way connector. The left ends of the two magnetically coupled rodless cylinders 2 are connected via air pipes 13 and a three-way connector, and the right ends are connected via air pipes 13 and a three-way connector.

[0026] Two magnetically coupled rodless cylinders 2 are identical in model, specifications, and dimensions, and are arranged in parallel on the front and rear sides of the automatic door opening frame. The stroke of the magnetically coupled rodless cylinders 2 is greater than or equal to the automatic door opening size, and can be selected as needed.

[0027] The magnetically coupled rodless cylinder 2 and the automatic door opening frame are fixed to the outer protective cover 15 of the machine tool with screws. If an automatic door is to be installed on the top of the outer protective cover of a vertical machining center, the vertical machining center has a head cover that needs to move up and down on the left side of the automatic door, and a wire groove boss on the right side. With an automatic door opening size of 700mm and a usable space of only 900mm for the automatic door structure, if a standard cylinder 2 is used, the usable space for the automatic door structure would be at least 2*700+150=1550mm. Therefore, a magnetically coupled rodless cylinder 2 with a stroke of 700mm is selected. In this case, the stroke of the magnetically coupled rodless cylinder 2 matches the automatic door opening size. The total length of the magnetically coupled rodless cylinder 2 is: 2*20.5 (fixed end of cylinder 2) + 62 (cylinder slider 3) + 700 (stroke) = 803mm. Using this structure can save almost half the installation space compared to the standard cylinder 2, and also meets the requirement of "only 900mm of usable space".

[0028] The magnetically coupled rodless cylinder 2 drives the slider 3 to move, causing the guide bridge on the slider 3 to move left and right, which in turn drives the bellows cover 4, which is connected to the guide bridge at one end, to unfold and retract.
