Description

Technical Field

[0001] The utility model relates to a safety door for a numerical control machine tool, in particular to a safety door for a numerical control machine tool that prevents chip accumulation, belonging to the technical field of numerical control machine tools. Background Technique

[0002] With the rapid development of modern manufacturing industry, numerical control machine tools, as high-precision and high-efficiency processing equipment, are widely used in various industrial fields. However, during the processing of numerical control machine tools, the generated waste chips often interfere with the normal operation of the machine tool. Especially the chips accumulated in the door groove of the safety door not only affect the normal opening and closing of the safety door but also may pose a threat to the safety of operators. Therefore, a safety door for a numerical control machine tool that prevents chip accumulation is needed.

[0003] Among them, the "safety door for a numerical control machine tool that prevents chip accumulation" disclosed in the patent application number "CN202222055853.8" is also an increasingly mature technology, including a safety door body and a door groove for the safety door body to slide. The door groove is provided with a guide rail with a triangular cross-section. The two ends of the guide rail extend along the length direction of the door groove and are respectively connected to the inner walls of the two ends of the door groove. The bottom of the safety door body is provided with a groove that cooperates with the guide rail. A discharge hopper is arranged below the door groove, and the door groove communicates with the discharge hopper. A discharge channel for chips to fall into the discharge hopper is formed between the guide rail and the door groove. By arranging a discharge hopper below the door groove to make the door groove communicate with the discharge hopper, a discharge channel for chips to fall into the discharge hopper is formed between the guide rail and the door groove. When waste chips enter the door groove, they will directly fall into the discharge hopper through the discharge channel, preventing waste chips from accumulating in the door groove and affecting the movement of the safety door body.

[0004] However, the above method still has the following defects in actual use: The two ends of the guide rail are respectively connected to the inner walls of the two ends of the door groove. Since there is no support in the middle of the guide rail, the guide rail is prone to being compressed and deformed under the action of the self-weight of the safety door body, affecting the normal use of the safety door. At the same time, due to the small interval between the guide rail and the door groove, when the guide rail is blocked, it is inconvenient for the staff to clean and maintain the residual chips in the guide rail. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a safety door for a numerical control machine tool that prevents chip accumulation, so as to solve the problems raised in the above background technique that the guide rail is prone to being compressed and deformed under the action of the self-weight of the safety door body, affecting the normal use of the safety door, and at the same time, when the guide rail is blocked, it is inconvenient for the staff to clean and maintain the residual chips in the guide rail.

The top end of the support block 4 is fixedly provided with a support rod 41. A plurality of support blocks 4 provide a stable supporting force for the support rod 41. The top end of the support rod 41 is fixedly provided with a sliding tube 42. Air outlet holes 43 are arranged on both sides of the sliding tube 42. A filter screen is arranged on the surface of the air outlet holes 43 to prevent debris from entering the inside of the sliding tube 42. A plurality of air outlet holes 43 are arranged at equal intervals for cleaning the remaining debris in the support frame 2. One end of the sliding tube 42 is fixedly provided with an air inlet pipe 45. A protection component 5 is arranged on the surface of the sliding tube 42. The protection component 5 blocks dust and debris to protect the staff. A collection component 7 is arranged at the bottom end of the support frame 2. The collection component 7 can accelerate the collection of debris.

[0026] A valve 46 is fixedly arranged in the middle of the air inlet pipe 45 to control opening and closing. Protection plates 21 are arranged on both sides of the top end of the support frame 2. The top ends of the inner walls of the two protection plates 21 are fixedly provided with slide rails 211.

[0027] The protection component 5 includes two receiving plates 51, two safety door bodies 52, two sliders 53 and two glass panels 54. The two receiving plates 51 are respectively slidably arranged on both sides of the surface of the sliding tube 42. The top end of each receiving plate 51 is fixedly provided with a safety door body 52. The top end of each safety door body 52 is fixedly provided with a slider 53. The middle of each safety door body 52 is fixedly provided with a glass panel 54, which is convenient for observing the internal situation of the numerically controlled machine tool body 1.
