An automatic door linkage device

Abstract

This utility model discloses an automatic door linkage device, including a machine tool housing. A ring-shaped transmission component is rotatably mounted on the upper end of the machine tool housing. Left and right door panels are mounted below the ring-shaped transmission component. Power mechanisms are connected to the left and right door panels respectively, and the left and right door panels are connected to the ring-shaped transmission component via left and right belt connectors. Under the action of the synchronous belt, the time difference caused by the movement of the left and right door cylinders of the double-door system is eliminated. When one cylinder of the double-door system is activated, the other cylinder can also move synchronously through the belt, enabling the left and right doors of the double-door system to operate synchronously and smoothly under the push of the cylinders. This solves the problem of asynchronous opening and closing of the automatic double-door system, ensuring the smooth operation of the automatic double-door system and the safety of the machine tool during operation.

Description

Technical Field

[0001] This utility model relates to the field of automatic door manufacturing technology, and in particular to an automatic door linkage device. Background Technology

[0002] The size of the workpiece door in a machine tool enclosure is limited by the size of the workpiece, which is particularly prominent in machining centers. Due to the large size of the parts being machined, the workpiece door often adopts an automatic double-door structure.

[0003] In automatic double-door structures, the left and right doors may not open synchronously when closing. One door may open before the other has even begun to open, or one door may reach its limit before the other does. This affects the machine tool's normal processing and the accuracy of signal arrival detection. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies, the purpose of this utility model is to provide an automatic door linkage device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] The lower end of the machine tool cover is equipped with a guide rail, and the lower ends of the left and right door panels are slidably connected to the guide rail.

[0008] The ring transmission includes: mounting components installed on both sides of the machine tool cover, a rotating shaft mounted on the mounting component, an annular belt mounted on the rotating shaft, and the upper and lower directions of the annular belt connected to the left and right belt connectors, respectively.

[0009] The mounting component includes: an adjustment seat mounted on the machine tool housing, a support mounted on the adjustment seat by connecting screws, and the rotating shaft mounted on the support.

[0010] A bearing is mounted on the rotating shaft, a roller is mounted on the bearing, and the annular belt is fitted onto the roller.

[0011] The upper end of the upper bearing is equipped with a retaining ring.

[0012] The power mechanism includes: horizontally mounted left and right cylinders, the movable ends of which are connected to the left and right door panels respectively through left and right door panel cylinder connectors.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention provides an automatic door linkage device that, under the action of a synchronous belt, eliminates the time difference caused by the movement of the cylinders of the left and right double doors. When one cylinder of the double door is activated, the other cylinder can also move synchronously through the belt, enabling the left and right doors of the double door to operate synchronously and smoothly under the push of the cylinders. This solves the problem of asynchronous opening and closing of automatic double doors, ensuring the smooth operation of the automatic double door and the safety of the machine tool during operation. It further ensures the normal processing of the machine tool and the accuracy of signal detection. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0021] like Figure 1 As shown, this utility model provides an automatic door linkage device, including: a machine tool cover, an annular transmission component rotatably mounted on the upper end of the machine tool cover, left and right door panels 1 and 2 mounted below the annular transmission component, a power mechanism connected to the left and right door panels 1 and 2 respectively, and the left and right door panels 1 and 2 connected to the annular transmission component through left and right belt connectors 8 and 6 respectively.

[0022] Preferably, in order to guide the movement of the door panel, so that the door panel runs stably and smoothly without deviation, a guide rail is installed at the lower end of the machine tool cover, and the lower ends of the left and right door panels 1 and 2 are slidably connected to the guide rail.

[0023] like Figure 2 As shown, the annular transmission includes: mounting components installed on both sides of the machine tool cover, a rotating shaft 5 mounted on the mounting components, an annular belt 9 mounted on the rotating shaft 5, and the upper and lower directions of the annular belt 9 connected to the left and right belt connectors 8 and 6, respectively.

[0024] Specifically, such as Figure 3 As shown, the mounting components include: an adjusting seat 12 mounted on the machine tool housing, a support 11 mounted on the adjusting seat 12 via connecting screws, and a rotating shaft 5 mounted on the support 11. A bearing 15 is mounted on the rotating shaft 5, a roller 4 is mounted on the bearing 15, and an annular belt 9 is fitted onto the roller 4. A retaining ring 14 is mounted on the upper end of the upper bearing 15. The roller 4 is fixed to the support 11 via the bearing 15 and the retaining ring 14. The adjusting seat 12 adjusts the spacing of the support 11 via screws, thereby adjusting the tension of the belt 9.

[0025] It should be noted that in this utility model, the power mechanism includes: horizontally installed left and right cylinders 10 and 16, and the movable ends of the left and right cylinders 10 and 16 are respectively connected to the left and right door panels 1 and 2 through left and right door panel cylinder connectors 3 and 13.

[0026] The left and right door panels 1 and 2 are connected to the inner and outer sides of the belt 9 through connectors 6 and 8 respectively, and are fixedly assembled into a whole by pressure plate 7. Under the pushing action of cylinder 10, the door panels reciprocate.

[0027] The working process of this utility model is as follows:

[0028] The left and right door panels 1 and 2 are assembled into a whole with the belt 9 and pressure plate 7 via the connectors 6 and 8. Under the push of the cylinder 10 rod, the door panel 12 reciprocates.

[0029] The belt 9, roller 4, bearing 15, shaft 5, retaining ring 14, support 11, and adjusting support 12 are assembled into a whole. The belt 9 is connected to the door panel connectors 6 and 8 and the pressure plate 7, and rotates by the roller 4 through the reciprocating motion of the door panel 12.

[0030] like Figure 4As shown, the left and right doors 1 and 2 are connected on both sides of the same belt 9, so as to achieve simultaneous and relatively opposite movements. The rotation of the belt 9 eliminates the time difference caused by the movement of the cylinders of the left and right doors 12 of the double doors. When one cylinder of the double doors is activated, the other cylinder can also move synchronously through the action of the belt 9, so that the left and right doors of the double doors can run synchronously and smoothly under the push of the cylinders 10 and 16.

[0031] It will be apparent to those skilled in the art that the above specific examples are merely preferred embodiments of this utility model. Therefore, any improvements or modifications that those skilled in the art may make to certain parts of this utility model still embody the principles of this utility model and achieve its purpose, and all fall within the scope of protection of this utility model.
