Description

Technical Field

[0001] The utility model belongs to the technical field of numerical control machine tools, and particularly relates to a double-opening synchronous movable door for a tool magazine of a vertical lathe. Background Technique

[0002] Large rotary parts are commonly machined by a vertical lathe machining center for rough and finish turning. The tool magazine of a vertical lathe often adopts a capstan-type tool changer. In order to prevent iron chips and cutting fluid, most of such tool magazines need to be equipped with a protective cover to protect the tools. An activity door is opened on the protective cover so that the spindle head can move to the tool magazine to change tools.

[0003] At present, many movable doors of tool magazines are driven by bilateral cylinders. This way of opening the door not only increases the setting of electronic components, but also causes the movable door to open unstably and easily leads to the asynchronous movement of the two side movable doors, thereby increasing the tool change time. Content of the Utility Model

[0004] The utility model provides a double-opening synchronous movable door for a tool magazine of a vertical lathe, aiming to solve the problem that at present, many movable doors of tool magazines are driven by bilateral cylinders. This way of opening the door not only increases the setting of electronic components, but also causes the movable door to open unstably and easily leads to the asynchronous movement of the two side movable doors, thereby increasing the tool change time.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A double-opening synchronous movable door for a tool magazine of a vertical lathe includes a shield support plate. There are grooves on the front side wall of the shield support plate. A left movable door and a right movable door are arranged in the grooves. A driving mechanism is installed on the top of the shield support plate. The driving mechanism is used to adjust the distance between the left movable door and the right movable door. The driving mechanism includes a first sprocket. The first sprocket is located on the top of the shield support plate and is rotatably connected to the shield support plate. A second sprocket is arranged on one side of the first sprocket. The second sprocket is rotatably connected to the shield support plate. A chain is arranged between the first sprocket and the second sprocket. The first sprocket and the second sprocket are connected by the chain for transmission. The left movable door is connected to the lower chain link group in the chain. The right movable door is connected to the upper chain link group in the chain. In this scheme, by setting the first sprocket, the second sprocket and the chain, when the left movable door moves to the left, it will drive the chain to displace, and then make the right movable door move to the right, so as to adjust the distance between the left movable door and the right movable door.

[0007] Preferably, a cylinder support base is provided on the side of the first sprocket away from the second sprocket. The cylinder support base is fixedly connected to the shield support plate. A mini cylinder is provided on the cylinder support base. The mini cylinder is connected to the cylinder support base. A connecting member is installed at the top of the left movable door. The output shaft of the mini cylinder is fixedly connected to the connecting member. In this solution, by providing the mini cylinder, the mini cylinder can drive the horizontal movement of the left movable door to make the chain move. At this time, the right movable door will move along with the movement of the chain, thereby quickly adjusting the distance between the left movable door and the right movable door.

[0008] Preferably, a first synchronous block is installed at the bottom of the chain. The left movable door is connected to the chain through the first synchronous block. A second synchronous block is provided behind the first synchronous block. The second synchronous block is fixedly connected to the chain. The right movable door is fixedly connected to the chain through the second synchronous block.

[0009] Preferably, a linear guide rail is further provided between the first sprocket and the second sprocket. The linear guide rail is fixedly connected to the shield support plate. A first slider and a second slider are slidably provided on the linear guide rail. The first slider is fixedly connected to the left movable door. The second slider is fixedly connected to the right movable door. In this solution, by providing the linear guide rail, the first slider and the second slider, when the left movable door and the right movable door move horizontally, the first slider and the second slider will also move horizontally on the linear guide rail, thereby providing guidance for the horizontal movement of the left movable door and the right movable door.

[0010] Preferably, a first rotating shaft is vertically provided inside the first sprocket. The first sprocket is rotatably connected to the shield support plate through the first rotating shaft. A second rotating shaft is vertically provided inside the second sprocket. The second sprocket is rotatably connected to the shield support plate through the second rotating shaft.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] 1. By providing a driving mechanism, the mini cylinder in the driving mechanism can drive the left movable door to move horizontally. At this time, the horizontally moving left movable door drives the right movable door to move horizontally through the first sprocket, the second sprocket and the chain, thereby adjusting the distance between the left movable door and the right movable door. This enables the device to achieve the opening and closing door function formed by the left movable door and the right movable door with only one mini cylinder. Compared with driving the left movable door and the right movable door to move horizontally by two cylinders respectively, the device can reduce the setting of electronic components, and the device will not increase the tool change time due to the asynchronous movement of the left movable door and the right movable door.
