Description

Technical Field

[0001] The utility model belongs to the field of machine tool tool magazine protection, and particularly relates to a tool magazine protection sliding door structure. Background Art

[0002] With the rapid development of the machine tool industry, users have higher and higher requirements for one-time clamping to complete machining, and there are more and more selections for tool magazine options. The tool magazine protection structure becomes more important. At present, there are mainly two types of tool magazine protection structures. One is an open structure, which mainly provides protection for the periphery of the tool magazine to isolate dangerous components. However, the tool magazine itself is directly exposed in the machining area, and it is inevitable that water chips will contaminate the tool magazine during machining, resulting in abnormal tool change. The other is an integral pneumatic door protection, which is equipped with a pneumatic sliding door between the tool magazine and the machining area to isolate the influence of machining. However, the pneumatic sliding door is large in size and slow in movement, which affects the tool change efficiency, and due to the need to open the door, it will greatly increase the floor space of the machine tool. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a tool magazine protection sliding door structure with small size, low cost, short opening and closing time, and capable of improving tool change efficiency in view of the deficiencies of the prior art.

[0004] The technical solution adopted by the utility model to solve the above technical problems is as follows: a tool magazine protection sliding door structure includes a protection main body, an inner sliding door, an outer sliding door, a telescopic hinge and a cylinder. The inner sliding door is arranged on the back side of the outer sliding door. The top and bottom of the front surface of the protection main body are respectively provided with an upper sliding door guide rail and a lower sliding door guide rail. The top and bottom of the inner sliding door are respectively slidably connected with the upper sliding door guide rail and the lower sliding door guide rail. The top and bottom of the outer sliding door are respectively slidably connected with the upper sliding door guide rail and the lower sliding door guide rail. The back surfaces of the inner sliding door and the outer sliding door are respectively provided with a first bracket and a second bracket. The first bracket and the second bracket are respectively connected with the telescopic hinge. The cylinder is installed on one side of the back surface of the protection main body, and the output end of the cylinder is connected with the first bracket.

[0005] When the structure of the protective sliding door of the tool magazine of the present utility model operates, the air cylinder serves as the power source to drive the inner sliding door to move. While the inner sliding door moves, the outer sliding door is driven to move synchronously through the telescopic hinge, realizing the opening and closing of the inner sliding door and the outer sliding door. The present utility model realizes the power transmission between the inner sliding door and the outer sliding door through the telescopic hinge, which can effectively reduce the overall size width of the sliding door structure. Moreover, the acting point of the air cylinder is the inner sliding door, and when the door is closed in place, the distance that the air cylinder needs to move is greatly reduced. Therefore, the stroke required by the air cylinder during the operation process is greatly reduced, which can reduce the cost. At the same time, the shortening of the air cylinder stroke and the reduction of the sliding door structure size also effectively shorten the time required for opening and closing the door, improving the tool change efficiency.

[0006] Preferably, the lower guide rail of the sliding door includes a U-shaped rail bracket arranged along the length direction of the protective main body, a first lower guide rail, a second lower guide rail, a first horizontal limiting plate and a second horizontal limiting plate. The U-shaped rail bracket is fixed on the protective main body. The second lower guide rail and the first lower guide rail are arranged in parallel front and back on the top of the U-shaped rail bracket. The second horizontal limiting plate and the first horizontal limiting plate are arranged in parallel front and back on the side of the U-shaped rail bracket. The bottom of the inner sliding door is provided with a first pulley and a first limiting roller with parallel center lines at an upper and lower interval. The first pulley is slidably installed on the first lower guide rail. The first limiting roller is located below the first horizontal limiting plate. The bottom of the outer sliding door is provided with a second pulley and a second limiting roller with parallel center lines at an upper and lower interval. The second pulley is slidably installed on the second lower guide rail. The second limiting roller is located below the second horizontal limiting plate. During the movement of the inner sliding door and the outer sliding door, if the inner sliding door and the outer sliding door jump, the first limiting roller will contact the first horizontal limiting plate, and the first horizontal limiting plate can play a guiding and upper limiting role in the movement of the first limiting roller. Similarly, the second limiting roller will contact the second horizontal limiting plate, and the second horizontal limiting plate can play a guiding and upper limiting role in the movement of the second limiting roller, thus ensuring the safe operation of the inner sliding door and the outer sliding door and preventing the inner sliding door and the outer sliding door from derailing.

[0007] Preferably, first protective plates and second protective plates are respectively fixed on both sides in the length direction of the protective main body. There is a window between the first protective plate and the second protective plate. The inner sliding door and the outer sliding door are used to open and close the window. The widths of the first protective plate, the inner sliding door and the outer sliding door are similar. The air cylinder is installed on the back of the first protective plate. On the premise of ensuring the opening space size required for the tool change operation, the design of the above-mentioned protective main body is beneficial to minimizing the space occupied when the sliding door structure is opened to the greatest extent.

[0008] Compared with the prior art, the utility model has the following advantages: the utility model realizes the power transmission between the inner sliding door and the outer sliding door through a telescopic hinge, which can effectively reduce the overall size width of the sliding door structure, and the acting point of the air cylinder is the inner sliding door. When the door is closed in place, the distance that the air cylinder needs to move is greatly reduced, so the stroke required by the air cylinder during the operation process is greatly reduced, which can reduce the cost. At the same time, the shortening of the air cylinder stroke and the reduction of the sliding door structure size also effectively shorten the time required for opening and closing the door, improving the tool change efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following further describes the present utility model in detail with reference to the embodiments of the drawings. The structures or components not defined in the present utility model all adopt the conventional technical means in the art.

[0018] The tool magazine protection sliding door structure of the embodiment is as Figures 1 to 6As shown in the figure, it includes a protection body 1, an inner sliding door 2, an outer sliding door 3, a telescopic hinge 4 and a cylinder 5. On both sides of the protection body 1 in the length direction, a first protection plate 11 and a second protection plate 12 are respectively fixed. There is a window 13 between the first protection plate 11 and the second protection plate 12. The inner sliding door 2 and the outer sliding door 3 are used to open and close the window 13. The widths of the first protection plate 11, the inner sliding door 2 and the outer sliding door 3 are similar. The cylinder 5 is installed on the back of the first protection plate 11. The inner sliding door 2 is arranged on the back side of the outer sliding door 3. At the top and bottom of the front of the protection body 1, an upper sliding door guide rail 6 and a lower sliding door guide rail 7 are respectively installed. The top and bottom of the inner sliding door 2 are respectively slidably connected to the upper sliding door guide rail 6 and the lower sliding door guide rail 7. The top and bottom of the outer sliding door 3 are respectively slidably connected to the upper sliding door guide rail 6 and the lower sliding door guide rail 7. On the backs of the inner sliding door 2 and the outer sliding door 3, a first bracket 21 and a second bracket 31 are respectively installed. The first bracket 21 and the second bracket 31 are respectively connected to the telescopic hinge 4. The output end of the cylinder 5 is connected to the first bracket 21.

[0019] In this embodiment, the lower sliding door guide rail 7 includes a U-shaped guide rail bracket 71 arranged along the length direction of the protection body 1, a first lower guide rail 72, a second lower guide rail 73, a first horizontal limiting plate 74 and a second horizontal limiting plate 75. The U-shaped guide rail bracket 71 is fixed on the protection body 1. The second lower guide rail 73 and the first lower guide rail 72 are arranged in parallel front and back on the top of the U-shaped guide rail bracket 71. The second horizontal limiting plate 75 and the first horizontal limiting plate 74 are arranged in parallel front and back on the side of the U-shaped guide rail bracket 71. At the bottom of the inner sliding door 2, a first pulley 22 and a first limiting roller 23 with parallel center lines are installed at intervals up and down. The first pulley 22 is slidably installed on the first lower guide rail 72. The first limiting roller 23 is located below the first horizontal limiting plate 74. At the bottom of the outer sliding door 3, a second pulley 32 and a second limiting roller 33 with parallel center lines are installed at intervals up and down. The second pulley 32 is slidably installed on the second lower guide rail 73. The second limiting roller 33 is located below the second horizontal limiting plate 75.

[0020] When the above tool magazine protection sliding door structure operates, the cylinder 5 serves as a power source to drive the inner sliding door 2 to move. While the inner sliding door 2 moves, it drives the outer sliding door 3 to move synchronously through the telescopic hinge 4, realizing the opening and closing of the inner sliding door 2 and the outer sliding door 3.

[0021] The power transmission between the inner sliding door 2 and the outer sliding door 3 is realized through the telescopic hinge 4, which can effectively reduce the overall size width of the sliding door structure. Moreover, the acting point of the air cylinder 5 is the inner sliding door 2. When the door is closed in place, the distance that the air cylinder 5 needs to move is greatly reduced. Therefore, the stroke required for the air cylinder 5 during the operation process is greatly reduced, which can reduce the cost. At the same time, the shortening of the stroke of the air cylinder 5 and the reduction of the size of the sliding door structure also effectively shorten the time required for opening and closing the door, improving the tool change efficiency. For example, compared with the tool magazine protection sliding door structure that conventionally uses a sliding door with a width of 970 mm (the distance that the air cylinder 5 needs to move when the door is closed in place is 830 mm), on the premise of achieving the same opening space size, the widths of the inner sliding door 2 and the outer sliding door 3 of the present utility model can be optimally designed to be 510 mm respectively. To achieve the sealing effect, on the premise that the inner sliding door 2 and the outer sliding door 3 partially overlap when opening and closing the door, the overall width of the tool magazine protection sliding door structure can be reduced by 460 mm. When the door is closed in place, the distance that the air cylinder 5 needs to move is reduced from 830 mm to 420 mm, and the stroke required for the air cylinder 5 is greatly reduced, and overall, about 20% of the cost can be saved.
