Description

Technical Field

[0001] The utility model relates to the technical field of machine tool protection doors, in particular to a sealed protection door for an intelligent equipment housing. Background Art

[0002] CNC machine tools are intelligent automatic workpiece processing equipment. They control the internal processing equipment to automatically turn and mill the workpiece by programming operation codes into the operating system. In order to avoid debris splashing everywhere during workpiece processing, an outer cover is provided on the outside of the machine tool processing equipment, and an automatically openable and closed protective door is provided on the outer cover. In order to better observe the working conditions of the internal processing equipment, an observation window is provided on the protective door. During the processing of CNC machine tools, not only metal debris will be generated, but also some harmful fumes will be generated. If these fumes leak from the inside of the CNC machine tools, it is easy to cause pollution to the production workshop environment and damage the health of the staff. Therefore, after the protective door is opened and closed, its sealing is the top priority to ensure the safety of the workshop. In addition, when the machine tool is processing inside, the metal chips flying around can easily hit the observation window. If it works for a long time, the metal chips will scratch the observation window, which will affect the normal observation and bring great inconvenience to the normal operation of the CNC machine tools.

[0018] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 1-5 As shown, the sealed protective door of the intelligent equipment shell described in this embodiment includes a protective door 2 which can be opened and closed and is arranged on the CNC machine tool shell 1, the protective door 2 is provided with an observation window 3, and an openable and closable protective cover 4 is provided on the inner side of the protective door 2 at a position corresponding to the observation window 3, a sealing strip 5 is provided on the side where the protective door 2 is connected to the shell 1, a sealing groove 11 is provided on the side of the shell 1 that is connected to the protective door 2, the sealing strip 5 is inserted into the sealing groove 11, and a plurality of serrated grooves 12 are evenly distributed on the shell 1 at positions corresponding to both sides of the sealing groove 11. After the protective door 2 is closed, the squeezed sealing strip 5 is filled in the serrated groove 12.

[0021] The sealing strip 5 is provided with a groove-shaped butt joint 51 on one side facing the sealing groove 11 . The butt joint 51 is made of soft rubber. When the butt joint 51 is squeezed, it will be deformed and filled into the toothed groove 11 .

[0022] Two protective covers 4 are provided, and the two protective covers 4 are symmetrically arranged on both sides of the observation hole 3 , and the two protective covers 4 are synchronously operated by the driving mechanism 6 .

[0023] The protective cover 4 includes an outer frame 41 , and a metal protective net 42 is arranged between the outer frames 41 .

[0024] The driving mechanism 6 includes a forward and reverse screw 61 placed horizontally above the observation window 3. The forward and reverse screw 61 is driven to rotate by a motor 62. Connecting blocks 43 are provided at the upper ends of the outer frames 41 on both sides. The connecting blocks 43 are respectively installed at the two ends of the forward and reverse screw 61 with opposite thread directions. When the motor 62 controls the forward and reverse screw 61 to rotate, it will move the connecting blocks 43 on both sides toward the observation window 3 at the same time or move away from the observation window 3 at the same time.

[0025] A guide rail 7 is provided on the protective door 2 at a position below the corresponding observation window 3 , and sliders 44 are provided at the lower ends of the outer frames 41 on both sides, and the sliders 44 are installed on the guide rail 7 .

[0026] Limit switches 8 are arranged on the protective door 2 at positions corresponding to the left and right sides of the slider 44. The triggers of the limit switches 8 are arranged toward one side of the slider 44. The limit switches 8 can control the motor 62 to stop working.

[0027] The limit switch 8 ensures that the protective cover 4 can be installed and operated. Once a problem occurs in the control system, causing the motor 62 to rotate uncontrollably, the slider 44 at the lower end will trigger the limit switch 8. At this time, the limit switch 8 will turn off the power supply, thereby preventing the protective covers 4 on both sides from excessively displacing and causing damage to the equipment.

[0028] The protective door 2 is also provided with a door handle 21 .

[0029] The protective door 2 is driven to open and close by an electric push rod (not shown in the figure).

[0030] The working principle of the utility model is as follows: when the workpiece is being processed, the electric push rod drives the protective door 2 to close. At this time, the side of the protective door 2 with the sealing strip 5 will move toward the end of the housing 1 with the sealing groove 11. When the protective door 2 is docked with the housing 1, the sealing strip 5 will be squeezed into the sealing groove 11, and the squeezed sealing strip 5 will also be deformed. After the joint 51 at the front end of the sealing strip 5 is deformed, it will fill the serrated groove 12. In this way, the sealing performance of the sealing strip 5 can be improved to prevent the leakage of smoke inside the CNC machine tool. During normal operation, the protective covers 4 on both sides move toward the center of the observation window 3 at the same time and cover the observation window 3. This In this way, flying metal chips will not directly impact the observation window, thereby better protecting the observation window 3. When the staff needs to observe the processing conditions inside the machine tool, they press the switch to control the motor 62 to rotate. The motor 62 drives the forward and reverse screws 61 to rotate. At this time, the connecting block 43 moves to both sides of the observation window 3 at the same time as the forward and reverse screws 62 rotate. At this time, the protective cover 4 avoids the observation window 3, and the staff can observe the conditions inside the machine tool through the observation window 3. After the observation is completed, the motor 62 can be controlled to reverse again. At this time, the two protective covers 4 will move to the center of the observation window 3 at the same time again. After the two protective covers 4 are docked, they continue to block and protect the observation window 3.

[0031] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
