Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of linkage doors, in particular to a cylinder type automatic double linkage door. Background Art
[0002] The automatic protective doors in the machining area of a vertical machining center are generally double-door double-opening type. Each door movement is driven by a separate cylinder, and the purpose of automatic synchronous opening or closing of the double doors is achieved through adjustment.
[0003] For a vertical machining center with a double-linked door in the machining area, when the cylinder drives the active door alone and then drives the driven door to realize the automatic opening or closing of the double-linked door, the cylinder needs to use a rodless cylinder with a larger stroke, which is more expensive. Utility Model Content
[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a cylinder type automatic double linkage door, which adopts an ordinary cylinder and utilizes the movable pulley principle of the linkage door to achieve the effects of short stroke, stable operation and low cost.
[0005] The technical solutions adopted in this application are as follows:
[0006] This solution provides a cylinder type automatic double linkage door, including:
[0007] A double linkage door consisting of an active door and a driven door, wherein the active door and the driven door are linked by a movable pulley;
[0008] Door covers, which are arranged on the outer tops of the active door and the driven door;
[0009] Also includes:
[0010] A thrust cylinder, a connecting bracket and a start-stop sensing device, wherein one end of the thrust cylinder is fixed on a side of the door frame close to the driven door, the connecting bracket is fixed on the driven door, the free end of the thrust cylinder is connected to the connecting bracket, the start-stop sensing device is fixed on the door frames at the beginning and end of the opening and closing strokes of the active door and the driven door, and the start-stop sensing device is used to control the action of the thrust cylinder to realize the opening and closing actions of the active door and the driven door.
[0011] In this solution, the start-stop sensing device includes a first non-contact sensor and a second non-contact sensor. The first non-contact sensor is installed on one side of the door frame, and the second non-contact sensor is installed on the other side of the door frame. The first non-contact sensor and the second non-contact sensor are respectively installed at the beginning and end of the opening and closing stroke of the active door and the driven door of the door frame.
[0012] In a further solution, the start-stop sensing device also includes a first baffle, a second baffle and a processor. The first baffle and the second baffle are both fixed on the active door. The first baffle is arranged on the side of the active door away from the thrust cylinder, and the second baffle is arranged on the side of the active door close to the thrust cylinder. The processor is connected to the thrust cylinder, the first non-contact sensor and the second non-contact sensor signals. The first baffle is used as a limit switch of the first non-contact sensor, and the second baffle is used as a limit switch of the second non-contact sensor. The first non-contact sensor and the second non-contact sensor communicate with the processor, and the processor controls the working state of the thrust cylinder.
[0013] In this solution, when the door is closed, the piston rod of the thrust cylinder extends and drives the double-linked door to move to the left (close to the side of the first non-contact sensor). When the first non-contact sensor senses the first baffle, it sends a signal to the processor, and the thrust cylinder stops moving.
[0014] When the door is opened, the piston rod of the thrust cylinder contracts, and when the second non-contact sensor senses the second baffle, it sends a signal to the processor, and the thrust cylinder stops moving.
[0015] In a preferred embodiment, the free end of the thrust cylinder is connected to the connecting bracket via a double elbow joint.
[0016] The beneficial effects achieved by the utility model using the above structure are as follows:
[0017] In the technical composition, the cylinder drives the driven door alone. By utilizing the movable pulley principle of the linkage door, the active door moves with the driven door, but the movement speed is twice that of the driven door, thereby realizing the automatic opening or closing of the double linkage doors at synchronous and different speeds.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0024] Example 1
[0025] Please refer to Figure 1-2 As shown, this embodiment provides a cylinder type automatic double linkage door, including a double linkage door consisting of an active door 1 and a driven door 2, wherein the active door 1 and the driven door 2 are linked by a movable pulley;
[0026] It also includes a door cover 3, which is arranged on the outer top of the active door 1 and the driven door 2. The door cover 3 is a protective sheet metal, and the protective sheet metal is used below to replace the concept of the door cover 3.
[0027] Combination Figure 1 and Figure 2 As shown, the present scheme also includes a thrust cylinder 4, a connecting bracket 5 and a start-stop sensing device 6. The start-stop sensing device 6 is fixed on the door frame 3 at the beginning and end of the opening and closing stroke of the active door 1 and the driven door 2. The start-stop sensing device 6 is used to control the action of the thrust cylinder 4 to realize the opening and closing action of the active door 1 and the driven door 2. The start-stop sensing device 6 includes a first non-contact sensor 61, a second non-contact sensor 62, a first baffle 63, a second baffle 64 and a processor.
[0028] As shown in the reference figure, the thrust cylinder 4 is fixed on the protective sheet metal as a fulcrum, the connecting bracket 5 is fixed on the driven door 2, the thrust cylinder 4 is connected to the connecting bracket 5 through a double elbow joint 7, the first baffle 63 and the second baffle 64 are both fixed on the active door 1, and the first non-contact sensor 61 and the second non-contact sensor 62 are respectively installed on the protective sheet metal at the beginning and end of the opening and closing stroke of the active door 1 and the driven door 2.
[0029] Here’s how it works:
[0030] When closing the door, the piston rod of the thrust cylinder 4 extends out, and drives the double-linked door to move to the left through the double elbow joint 7 and the connecting bracket 5. When the first non-contact sensor 61 senses the first baffle 63, it sends a signal to the processor, and the thrust cylinder 4 stops moving.
[0031] When the door is opened, the piston rod of the thrust cylinder 4 contracts, and drives the double door to move to the right through the double elbow joint 7 and the connecting bracket 5. When the second non-contact sensor 62 senses the second baffle 64, it sends a signal to the processor, and the thrust cylinder 4 stops moving.
[0032] When the utility model is used, the cylinder drives the driven door 2 alone. By utilizing the movable pulley principle of the linkage door, the active door 1 moves with the driven door 2, but the movement speed is twice that of the driven door 2, thereby realizing the automatic opening or closing of the double linkage doors synchronously at different speeds.
[0033] As an example to further illustrate:
[0034] The active door 1 and the driven door 2 are linked by a movable pulley. The chain is fixed, and the sprocket rotates and moves left and right with the door. Because it is a linkage door, the distance traveled by the active door 1 is twice that of the driven door 2 in the same time, and the two have different movement speeds.
[0035] In the embodiment, the cylinder selected for the automatic door is a common cylinder with short stroke, stable operation and low cost.
[0036] It should be noted that although the embodiments of the utility model have been shown and described, for ordinary technicians in this field, without departing from the inventive purpose of the utility model, structural methods and embodiments similar to the technical scheme without creative design should all fall within the scope of protection of the utility model.
