Description

Technical Field

[0001] The utility model relates to a door assembly and a cover shell for installing the door assembly, in particular to a door assembly suitable for a machine tool and a cover shell for installing the door assembly. Background Art

[0002] Machine tools are used to process metal parts. Common machine tools that require manual operation, such as lathes, drilling machines, and milling machines, generally do not require a cover. However, automated machine tools, such as CNC machines and machining centers, typically require a cover for protection. Common covers, such as those described in Patent Publication No. CN221363991U, entitled "An Adjustable Protective Cover," and Patent Publication No. CN219337026U, entitled "An Easy-to-Install Machine Tool Cover," typically have a door mounted centrally on the front side of the cover to facilitate manual operation.

[0003] However, parts that require more than two processing steps need to be converted between two machine tools. If a robot is used to move the workpiece, the machine door is still set in the central position, which is inconvenient for the robot to operate. Therefore, the machine door needs to be improved. Summary of the Invention

[0004] In order to overcome the deficiencies in the prior art, the utility model provides a door assembly and a cover shell for mounting the door assembly, which are suitable for being mounted on a machine tool.

[0007] The door panel is slidably connected to the shell, and the door panel can slide to overlap with the first door opening or staggered with each other.

[0008] Preferably, it further comprises an inner plate, which is fixedly connected to the inner side of the outer shell and forms a cavity with the outer shell, and the door panel slides into the cavity or slides to be staggered with the first door opening.

[0009] Preferably, the door panel slides back and forth in a vertical direction, and the inner panel is arranged above the first door opening.

[0010] Preferably, the inner side surface of the shell is fixedly connected to a guide rail, the outer side surface of the door panel is fixedly connected to a slider, and the slider is slidably connected to the guide rail; the shell is connected to a telescopic rod, the bottom of the door panel is fixedly connected to a flange plate, the flange plate extends to the outside of the shell, and the movable end of the telescopic rod is fixedly connected to the flange plate.

[0011] Preferably, the shell is bent twice in the same direction to form a first surface, a transfer surface and a second surface, the first door opening extends from the first surface to the transfer surface and the second surface in sequence, and the telescopic rod is fixedly connected to the outer side of the transfer surface.

[0012] Preferably, grooves are formed by bending on both sides of the door panel, and the sliders are connected to the grooves.

[0013] Preferably, both sides of the inner plate are bent to form convex edges, and both sides of the convex edges are fixed to the inner side surfaces of the outer shell.

[0014] Preferably, the bottom end of the door panel is connected to a bracket for fixing a door lock, and the outer shell is provided with a guard plate.

[0015] A cover shell comprises the door assembly described above.

[0016] Preferably, a second door opening is further provided on one of the side surfaces of the housing.

[0017] The utility model has the following technical effects:

[0018] The utility model arranges an opening for taking out a workpiece at a corner of a shell. When a workpiece needs to be processed by two machine tools in a continuous process, the first door openings of the two machine tools are arranged opposite to each other. A manipulator takes out the workpiece from the first door opening of one of the machine tools and puts it into the first door opening of the other machine tool, thereby shortening the distance the manipulator transfers the workpiece and improving the processing efficiency of the workpiece.

DETAILED DESCRIPTION

[0022] The following describes the principles and features of the present invention in conjunction with the examples; the examples are only used to explain the present invention and are not used to limit the scope of the present invention. Figure 2 The A side of the Figure 2 Side B in the.

[0023] A door assembly comprises an outer shell 1, a door panel 3 and an inner panel 4.

[0024] The housing 1 has a first door opening 2 extending from one side of the housing 1 to the adjacent side. Specifically, the housing 1 is formed by bending, with both sides of the housing 1 being bent in the same direction to form a first surface 9, a transition surface 10, and a second surface 11. The first surface 9 and the second surface 11 are perpendicular to each other, and the transition surface 10 is disposed at a 45° angle to each of the first surface 9 and the second surface 11. The first door opening 2 extends from the first surface 9 to the second surface 11.

[0025] The door panel 3 is slidably connected to the outer shell 1 and can slide to overlap with or offset from the first door opening 2. The door panel 3 slides back and forth in a vertical direction. When it slides downward, it overlaps with the first door opening 2 and covers it. When it slides upward, it offsets from the first door opening 2. The sliding of the door panel 3 is driven by a telescopic rod 7, which can be an electric push rod, a hydraulic rod, or a pneumatic rod. The telescopic rod 7 is fixedly connected to the outer side of the outer shell 1. The door panel 3 is arranged on the inner side of the outer shell 1. Specifically, the telescopic rod 7 is fixedly connected to the outer side of the center rotation surface 10. The bottom of the door panel 3 is fixedly connected to a flange plate 8, which extends outside the outer side of the outer shell 1. The movable end of the telescopic rod 7 is fixedly connected to the flange plate 8. The extension or contraction of the telescopic rod 7 drives the door panel 3 to move up and down. The inner side of the outer shell 1 is fixedly connected to the guide rail 5, and the outer side of the door panel 3 is fixedly connected to the slider 6, which is slidably connected to the guide rail 5. Specifically, the door panel 3 has grooves 12 formed by bending on both sides, and the slider 6 is connected to the groove 12. The bottom end of the door panel 3 is connected to a bracket 16 for fixing the door lock. The door lock on the machine tool generally adopts a limit switch structure. The housing 1 is provided with a guard plate 17 at the position corresponding to the bracket 16. When the door panel 3 slides downward to the closed position, the bracket 16 is inserted into the guard plate 17.

[0026] Inner panel 4 is fixedly attached to the inside of outer shell 1. Its two side edges are bent to form flanges 13, which are fixed to outer shell 1 on both sides to form a chamber. Door panel 3 is positioned above first door opening 2. When door panel 3 slides upward into the chamber, it becomes offset from first door opening 2.

[0027] A door assembly can be integrated into the cover 14 and is suitable for installation on a machine tool. At the same time, in order to facilitate manual operation, a second door opening 15 is provided on one side of the housing 1 to facilitate manual operation.

[0028] Conventional machine tool door assemblies are located in the middle of the front face, making them suitable for manual workpiece removal. This device changes the door assembly's location on the housing 14, making it suitable for robotic operation. When a workpiece requires two machine tools to process, the first door openings 2 of the two machines must be positioned opposite each other.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
