Description

Technical Field

[0001] This utility model belongs to the field of machine tool manufacturing, specifically a safety protection door. Background Technology

[0002] As machining technology becomes more and more mature, the processing speed and production efficiency of CNC machine tools and other processing equipment continue to improve. In order to improve the safety of machine tools and other processing equipment when processing workpieces, protective doors will be installed to protect personnel.

[0003] Existing protective doors for CNC machine tools or other processing equipment are operated by personnel pushing them to close the processing environment, isolating the equipment from the outside and preventing personnel from contacting it, thus protecting personnel. However, because these protective doors are manually closed, they are prone to pinching people's hands during closure. Furthermore, it is impossible to ensure that the door is securely closed. If the door is not securely closed, personnel are likely to accidentally come into contact with the operating machine tool or processing equipment, causing injury and reducing safety during use.

[0004] In summary, this utility model provides a safety door to solve the above problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A safety gate includes two limiting mechanisms, with a safety gate positioned between the two limiting mechanisms. Each limiting mechanism includes a guide rail, an automatic reset component on one side of the upper guide rail, guide sliders slidably connected to both sides of the guide rail surface, and the guide sliders connected to the safety gate. Both sides of the safety gate are equipped with positioning detection components. A rodless cylinder is located on one side of the top of the upper guide rail, and an automatic disengagement component is located at the bottom of the rodless cylinder.

[0007] Furthermore, in this utility model, the automatic disengagement assembly is composed of a connecting plate, a ball sleeve, and a column sleeve. The upper and lower ends of the back of the connecting plate are respectively connected to the rodless cylinder and the ball sleeve. One end of the column sleeve is connected to the guide slider on the right side, and the other end of the column sleeve is connected to the ball sleeve.

[0008] Furthermore, in this utility model, the automatic reset component includes a spring, which is sleeved on one side of the upper guide rail surface. Both ends of the spring are fixedly connected to nylon protective blocks, which are located on the surface of the guide rail and are slidably connected to the surface of the guide rail.

[0009] Furthermore, in this utility model, both ends of the guide slide rail and the rodless cylinder are fixedly connected to mounting brackets, and one side of the mounting bracket is provided with a mounting hole. One side of the nylon protective block on the left side is fixedly connected to the mounting bracket at one end of the guide slide rail.

[0010] Furthermore, in this utility model, the positioning detection components on both sides of the safety door are electromagnetic switches, and the electromagnetic switch model is A3144.

[0011] Beneficial effects: This utility model has the following beneficial effects:

[0012] This invention utilizes a rodless cylinder to drive an automatic disengagement component and a guide slider, causing the guide slider to slide the safety door left and right. During the sliding process, the guide rail limits the movement of the guide slider and the safety door, ensuring the stability of the safety door's movement. Position detection devices installed on both sides of the safety door activate the machine tool or other equipment to begin processing and detection when the safety door is closed, in conjunction with an external controller. Conversely, when the safety door is open, the machine tool or other equipment automatically stops processing, thus preventing operator injury due to misoperation. If the safety door impacts a person's hand when closing, the automatic disengagement component will automatically disengage the rodless cylinder and the safety door, preventing injury and effectively improving safety during use. An automatic reset component can reset the safety door, and the automatic disengagement component can then reconnect the safety door and the rodless cylinder for easy re-operation in future applications.

[0018] To better understand the technical content of this utility model, specific embodiments are described below in conjunction with the accompanying drawings. Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0019] Example 1

[0020] like Figure 1-3 As shown, this is the first embodiment of the present invention. This embodiment provides a safety protection door, including a limiting mechanism 1. There are two limiting mechanisms 1, and a safety door 2 is provided between the two limiting mechanisms 1. The limiting mechanism 1 includes a guide rail 11. An automatic reset component 3 is provided on one side of the upper guide rail 11. Guide sliders 12 are slidably connected to both sides of the surface of the guide rail 11, and the guide sliders 12 are connected to the safety door 2. Position detection components are installed on both sides of the safety door 2. A rodless cylinder 5 is provided on one side of the top of the upper guide rail 11, and an automatic disengagement component 4 is provided at the bottom of the rodless cylinder 5.

[0021] like Figure 1-3 As shown, the rodless cylinder 5 drives the automatic disengagement assembly 4 and the guide slider 12 to move, causing the guide slider 12 to slide the safety door 2 left and right. During the sliding process, the guide rail 11 can limit the guide slider 12 and the safety door 2 to ensure the stability of the safety door 2 during movement. Position detection devices installed on both sides of the safety door 2 transmit signals to the external controller when the safety door 2 is closed, and the external controller then controls the machine tool and other equipment to start processing and inspection. Conversely, when the safety door 2 is open, the external controller will automatically control the machine tool and other equipment to... Processing is stopped to prevent operator injury due to misoperation. If the safety door 2 hits a person's hand when it is closed, the automatic disengagement component 4 will automatically disengage the rodless cylinder 5 from the safety door 2, thus preventing injury to the person's hand and effectively improving safety during use. When the safety door 2 is disengaged and slides to the left, it will contact the automatic reset component 3. The reset force of the automatic reset component 3 will drive the safety door 2 to slide to the right, where it will meet the rodless cylinder 5 again when it reopens. Then, the automatic disengagement component 4 will automatically reconnect the safety door 2 and the rodless cylinder 5 to their original positions, facilitating future restarts.

[0022] Example 2

[0023] Reference Figure 2 and3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0024] In this embodiment, the automatic disengagement component 4 is composed of a connecting plate, a ball sleeve, and a column sleeve. The upper and lower ends of the back of the connecting plate are connected to the rodless cylinder 5 and the ball sleeve, respectively. One end of the column sleeve is connected to the right guide slider 12, and the other end of the column sleeve is connected to the ball sleeve.

[0025] The automatic reset assembly 3 includes a spring 32, which is sleeved on one side of the surface of the upper guide rail 11. Both ends of the spring 32 are fixedly connected to nylon protective blocks 31, which are located on the surface of the guide rail 11 and are slidably connected to the surface of the guide rail 11.

[0026] like Figure 2 and 3 As shown, when the safety door 2 collides with a person's hand, the force is transmitted to the ball sleeve and the column sleeve. The ball sleeve and the column sleeve separate by rolling and sliding, which causes the rodless cylinder 5 and the safety door 2 to automatically disengage, thus preventing injury to the person's hand. When the safety door 2 disengages and slides to the left, it will cause the guide slider 12 on one side to contact the nylon protective block 31. The force on the nylon protective block 31 will compress the spring 32, and the restoring force of the spring 32 will cause the nylon protective block 31 and the safety door 2 to return to one side, which will cause the safety door 2 to slide to the right. Then the safety door 2 can meet the rodless cylinder 5 again after it is reopened. Therefore, the ball sleeve and the column sleeve will reconnect, so that the safety door 2 and the rodless cylinder 5 will also automatically reconnect and return to their original positions.

[0027] Example 3

[0028] Reference Figure 1 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0029] In this embodiment, both ends of the guide rail 11 and the rodless cylinder 5 are fixedly connected to mounting brackets, and one side of the mounting bracket is provided with a mounting hole. One side of the left nylon protective block 31 is fixedly connected to the mounting bracket at one end of the guide rail 11.

[0030] The arrival detection devices on both sides of safety door 2 are electromagnetic switches, and the electromagnetic switch model is A3144. The output terminal of the electromagnetic switch is connected to the input terminal of an external controller, and the output terminal of the external controller is connected to the input terminal of machine tools and other equipment.

[0031] like Figure 1As shown, the mounting bracket facilitates the installation of the guide rail 11 and the rodless cylinder 5, ensuring their stability during use. The positioning detection component uses an electromagnetic switch, which is connected to an external controller. The external controller is connected to machine tools and other equipment. When the electromagnetic switch senses that the safety door 2 is closed, it transmits a signal to the external controller, which then controls the machine tools and other equipment to start processing and detection. Conversely, if the safety door 2 is open or not closed properly, the external controller will automatically stop the machine tools and other equipment, thereby improving their safety.

[0032] In operation, the rodless cylinder 5 first drives the automatic disengagement assembly 4 and the guide slider 12 to move, causing the guide slider 12 to slide the safety door 2 left and right. During the sliding process, the guide rail 11 limits the guide slider 12 and the safety door 2, ensuring the stability of the safety door 2 during movement. Since there are positioning detection devices installed on both sides of the safety door 2, when the safety door 2 is closed in place, the positioning detection devices will transmit a signal to the external controller, which will then control the machine tool and other equipment to start processing and testing. Conversely, when the safety door 2 is open or not closed in place, the positioning detection devices will transmit a signal to the external controller, which will then control the machine tool and other equipment to automatically stop processing. This prevents operators from coming into contact with the operating machine tool and other equipment, thus preventing injury. Furthermore, if the safety door 2 is impacted during the closing process... When the object reaches the user, the impact force is transmitted to the ball sleeve and the column sleeve. The ball sleeve and the column sleeve separate through rolling and sliding, which causes the rodless cylinder 5 and the safety door 2 to automatically disengage, thus preventing injury to the user's hand and effectively improving safety during use. When the safety door 2 disengages, it slides to the left, which causes the safety door 2 to drive the guide slider 12 on one side to contact the nylon protective block 31. The force on the nylon protective block 31 compresses the spring 32, and the restoring force of the spring 32 causes the nylon protective block 31 and the safety door 2 to return to one side, which causes the safety door 2 to slide to the right. The safety door 2 can then meet the reopened rodless cylinder 5 again, so the ball sleeve and the column sleeve will reconnect, and the safety door 2 and the rodless cylinder 5 will also automatically reconnect and return to their original positions, which facilitates subsequent re-drive.
