[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Referring to Figure 1 , an embodiment provided by the present utility model: an electrical automation processing machine tool, including a machine body 1, a controller 2 is fixedly connected to the left side of the front surface of the machine body 1, a pedal 3 is slidably connected to the bottom of the machine body 1, the pedal 3 is used for safety operations such as anti-electricity and anti-slip, and at the same time the pedal 3 can slide backward and enter the bottom of the machine body 1 for storage, a protective door 4 is slidably connected to the front surface of the machine body 1, and a glass observation window is fixedly connected to the front surface of the protective door 4. The staff can directly monitor and observe the processing situation inside the machine body 1 through the observation window.

[0033] Referring to Figures 2 - 4 , a limit box 5 is fixedly connected to the inner wall of the left side of the front surface of the machine body 1. The front surface of the limit box 5 and the front surface of the machine body 1 are on the same horizontal plane to avoid hindering the movement of the protective door 4. The limit box 5 is embedded in the front inner wall of the machine body 1 and is fixedly connected to the machine body 1 through bolts. When the parts inside the limit box 5 are damaged, the bolts can be directly screwed to release the fixed limit of the limit box 5, so that the limit box 5 can be directly removed for repair. A clamping unit is arranged inside the limit box 5. The clamping unit includes an electromagnet 51. The electromagnet 51 is fixedly connected to the center of the inner bottom surface of the limit box 5. The electromagnet 51 is electrically connected to the controller 2. Before the machine tool starts to run, the electromagnet 51 is controlled to be energized through the controller 2. When the processing ends and stops or the stop button is pressed, the power supply to the electromagnet 51 is stopped. This is a simple PLC control technology in the art and will not be elaborated here. A clamping elastic member 52 is fixedly connected to the inner bottom surface of the limit box 5. The clamping elastic member 52 includes a telescopic rod and a tension spring. A magnetic block 53 is fixedly connected to the front end of the clamping elastic member 52. The magnetic block 53 is inserted into the limit box 5. The magnetic block 53 can only move linearly in the front-back direction inside the limit box 5. When the magnetic block 53 moves forward, the clamping elastic member 52 can be pulled, so that the clamping elastic member 52 is stretched to generate elastic potential energy. The size of the magnetic block 53 is adapted to the size of the through groove 6.

[0034] When the electromagnet 51 is energized, it can generate the same magnetic force as the bottom of the magnetic block 53, repel the magnetic block 53, cause the magnetic block 53 to move forward, and pull the clamping elastic member 52. When the processing ends or the stop button is pressed, the electromagnet 51 stops being energized and the generated magnetic force disappears. At this time, the magnetic block 53 will quickly reset under the action of the elastic potential energy of the clamping elastic member 52 and enter the limit box 5.

[0035] A through groove 6 is provided on the left side of the front surface of the protective door 4. When the protective door 4 moves to the left and closes, the through groove 6 will be aligned with the magnetic block 53. At this time, when the electromagnet 51 is energized to push the magnetic block 53 out of the limit box 5, the magnetic block 53 can be clamped into the through groove 6 to fix the protective door 4, so that the protective door 4 remains closed during the processing, preventing the protective door 4 from being opened during the processing. A glass plate 7 is fixedly connected to the front side inside the through groove 6. The staff can observe the situation inside the through groove 6 through the glass plate 7. The front surface of the glass plate 7 is on the same horizontal plane as the front surface of the protective door 4, which is convenient for the staff to judge the state of the moving block 8.

[0036] A moving block 8 is arranged on the front side of the glass plate 7. The back surface of the moving block 8 fits with the front surface of the glass plate 7. A linkage unit is arranged on the rear side of the moving block 8. The linkage unit includes a connecting rod 81. The connecting rod 81 is fixedly connected to the back surface of the moving block 8. The rear end of the connecting rod 81 passes through the glass plate 7. The rear end of the connecting rod 81 is fixedly connected to a push plate 82. When the push plate 82 moves, it can drive the moving block 8 to move synchronously through the connecting rod 81. During the process of the magnetic block 53 being clamped into the through groove 6, it will push the push plate 82, and then drive the moving block 8 to move forward and separate from the glass plate 7. When the magnetic block 53 does not enter the through groove 6, the moving block 8 remains in contact with the front surface of the glass plate 7. The staff can quickly judge whether the protective door 4 is locked by observing the positional relationship between the moving block 8 and the glass plate 7. At the same time, the protruding moving block 8 can also enable the staff to see it at a glance, reducing the situation of overlooking the inspection of whether the protective door 4 is fully closed and locked.

[0037] Refer to Figure 3 and Figure 5The left and right surfaces of the protective door 4 are fixedly connected with protective elastic parts 9, and the end of the protective elastic part 9 away from the protective door 4 is fixedly connected with a protective plate 10. When the protective plate 10 moves toward the protective elastic part 9, the protective elastic part 9 can be squeezed, so that the protective elastic part 9 is compressed to generate elastic potential energy. The end of the protective plate 10 away from the protective elastic part 9 is fixedly connected with a rubber pad 11. During the movement of the protective door 4, if the left and right sides collide with an object or the hand of the staff, the rubber pad 11 can perform preliminary buffering protection, and then further protection treatment is performed by compressing the protective elastic part 9 to generate elastic potential energy, thereby reducing damage to the object or injury to the staff. A baffle 12 is fixedly connected to the upper surface of the protective plate 10. The baffle 12 is located directly above the protective elastic part 9, and the back of the baffle 12 is in contact with the front of the protective door 4. The baffle 12 can block the gap between the protective plate 10 and the protective door 4 to prevent impurities from being stuck in the gap and affecting the movement and protection effect of the protective plate 10.

[0038] Working principle: After the workpiece is placed into the body 1, the staff pulls the protective door 4 to close it. When the protective door 4 moves to the left and closes, the controller 2 controls the electromagnet 51 to be energized. At this time, the electromagnet 51 generates the same magnetic force as the bottom of the magnetic block 53, repels the magnetic block 53, and makes the magnetic block 53 move forward to be engaged and enter the through groove 6, so as to engage and fix the protective door 4. When the magnetic block 53 engages and enters the through groove 6, it pushes the push plate 82, and then drives the moving block 8 to be separated from the glass plate 7 forward. The staff can quickly judge whether the protective door 4 is locked by observing whether the moving block 8 is protruding. At the same time, the protruding moving block 8 can also make the staff see it at a glance. When the processing is stopped or the static stop button is pressed, the electromagnet 51 will be automatically powered off. The magnetic block 53 will quickly reset and enter the limit box 5 under the elastic potential energy of the engaging elastic member 52, and quickly release the engagement and fixation of the protective door 4, so that the protective door 4 can be quickly opened.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
