Description

Technical Field

[0001] This utility model relates to the field of machine tool protection, specifically a safety protection door lock for a multi-axis linkage machine tool. Background Technology

[0002] A multi-axis machine tool is a machine tool with multiple coordinate axes (including linear and rotary axes) that can move simultaneously and coordinately under the control of a computer numerical control (CNC) system to perform machining. Multi-axis machine tools typically include five-axis, seven-axis, and nine-axis types, with five-axis machine tools being the most common and widely used. A five-axis machine tool has at least five coordinate axes (three linear and two rotary) that can move simultaneously and coordinately under the control of a CNC system to perform machining. Five-axis machine tools are high-tech, high-precision machine tools specifically designed for machining complex curved surfaces. They can complete multi-face machining in a single setup and are suitable for aerospace, military, and scientific research fields.

[0003] However, existing multi-axis machine tools still have the following problems during use:

[0004] While existing multi-axis linkage machine tools can coordinate movements for processing, errors in coordination require manual removal of the workpiece from the machine tool. This increases the risk of accidental injury to workers operating the machine and reduces worker safety. Therefore, it is necessary to develop a safety lock for multi-axis linkage machine tools to be used in the field of machine tool protection. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, although existing multi-axis linkage machine tools can coordinate movements for processing, if errors occur during coordination, the workpiece needs to be manually removed from the multi-axis linkage machine tool. This makes it easy for workers to suffer accidental injuries while operating the machine tool, reducing worker safety. This utility model proposes a safety protection door lock for multi-axis linkage machine tools.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a safety protection door lock for a multi-axis linkage machine tool, comprising:

[0007] A multi-axis linkage machine tool body, on which a glass window is fixedly mounted, and a control switch is fixedly mounted on the top surface of the inner wall of the multi-axis linkage machine tool body. The control switch is located inside the glass window and is equipped with a switch button.

[0008] The safety protection mechanism includes fixed blocks. Two sets of fixed blocks are fixedly assembled on the glass window. Each set of fixed blocks consists of two blocks. Extension blocks are fixedly assembled on the two sets of fixed blocks. A connecting block is fixedly assembled between the two extension blocks. The connecting block is located between two movable blocks. Traction rods are symmetrically and movablely assembled on the connecting block. Limit blocks are fixedly assembled at one end of the two traction rods. Traction blocks are fixedly assembled at the other end of the two traction rods. A pressing rod is fixedly assembled on the traction block. The pressing rod is close to the switch button on the control switch.

[0009] Preferably, guide rods are fixedly assembled between the fixed blocks, and double threaded screws are movably assembled on the two sets of fixed blocks. A second equal diameter bevel gear is fixedly assembled at one end of the double threaded screw.

[0010] Preferably, the double-threaded screw is provided with two external threads, the two external threads on the double-threaded screw are in opposite directions, and the external threads on the double-threaded screw are respectively located between the two fixed blocks in each group.

[0011] Preferably, the external threads on the double-threaded lead screw are all threaded with movable blocks, and the movable blocks are movably assembled with the guide rod.

[0012] Preferably, each of the movable blocks has an operating plate fixedly mounted on its end face.

[0013] Preferably, a fixing plate is fixedly mounted on both symmetrical sides of the traction block, and an adjusting rod is movably mounted on each fixing plate, with the other end of the adjusting rod corresponding to the operating plate for movable assembly.

[0014] Preferably, a door frame is fixedly mounted on the glass window, a rotating rod is movably mounted on the door frame, and a transparent door is fixedly mounted on the rotating rod, with the transparent door located inside the door frame.

[0015] Preferably, a first equal-diameter bevel gear is fixedly mounted on the top of the rotating rod, and the first equal-diameter bevel gear and the second equal-diameter bevel gear are toothed together. A lock is fixedly mounted on the transparent door.

[0016] The advantages of this utility model are:

[0017] This invention utilizes the rotation of the second equal-diameter bevel gear to cause the two external threads on the double-threaded screw to rotate on the movable block, which in turn moves on the guide rod. Under the action of the adjusting rod, the traction block drives the traction rod to move on the connecting block. The traction block then drives the pressing rod to press the switch button on the control switch, thereby stopping the operation of the multi-axis linkage machine tool and improving safety.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0030] The following is in conjunction with the appendix Figure 1 —5 provides further detailed description of this application.

[0031] This application discloses a safety lock for a multi-axis machine tool. (Refer to...) Figure 1 and Figure 2 as well as Figure 5 A safety lock for a multi-axis machine tool includes a machine tool body 10, a glass window 11 fixedly mounted on the machine tool body 10, a control switch 20 fixedly mounted on the top surface of the inner wall of the machine tool body 10, the control switch 20 being located inside the glass window 11, and a switch button 21 mounted on the control switch 20. A safety protection mechanism 30 is mounted on the glass window 11, the safety protection mechanism 30 including fixing blocks 3000, and two sets of fixing blocks 3000 fixedly mounted on the glass window 11. On window 11, each set of fixing blocks 3000 consists of two blocks. A guide rod 3001 is fixedly mounted between each pair of fixing blocks 3000 in each set. A double-threaded screw 3002 is movably mounted on each of the two sets of fixing blocks 3000. A second equal-diameter bevel gear 3003 is fixedly mounted at one end of the double-threaded screw 3002. The double-threaded screw 3002 has two external threads, which are in opposite directions. The external threads on the double-threaded screw 3002 are located at the two points in each set. Between the fixed blocks 3000, the external threads of the double-threaded lead screw 3002 are threaded with movable blocks 3004 that move on the guide rod 3001. Each movable block 3004 has an operating plate 3005 fixedly mounted on its end face. Extension blocks 3006 are fixedly mounted on both sets of fixed blocks 3000. A connecting block 3007 is fixedly mounted between the two extension blocks 3006. The connecting block 3007 is located between the two movable blocks 3004. Traction rods 3008 are symmetrically and movably mounted on the connecting block 3007. One end of the guide rod 3008 is fixedly equipped with a limit block 3009, and the other end of the two traction rods 3008 is fixedly equipped with a traction block 3010. The two symmetrical sides of the traction block 3010 are fixedly equipped with a fixing plate 3011. The fixing plate 3011 is movably equipped with an adjusting rod 3012. The other end of the adjusting rod 3012 is movably assembled with the operation plate 3005. The traction block 3010 is fixedly equipped with a pressing rod 3013, which is close to the switch button 21 on the control switch 20.

[0032] In this utility model, the rotation of the second equal diameter bevel gear 3003 causes the two external threads on the double threaded screw 3002 to rotate on the movable block 3004, which in turn moves on the guide rod 3001. Under the action of the adjusting rod 3012, the traction block 3010 drives the traction rod 3008 to move on the connecting block 3007. The traction block 3010 drives the pressing rod 3013 to press the switch button 21 on the control switch 20, thereby stopping the operation of the multi-axis linkage machine tool body 10.

[0033] Reference Figures 2-4 A door frame 12 is fixedly mounted on the glass window 11. A rotating rod 23 is movably mounted on the door frame 12. A transparent door 13 is fixedly mounted on the rotating rod 23. The transparent door 13 is located inside the door frame 12. A first equal diameter bevel gear 22 is fixedly mounted on the top of the rotating rod 23 and has its teeth threadedly engaged with the second equal diameter bevel gear 3003. A lock 31 is fixedly mounted on the transparent door 13.

[0034] In this utility model, the key is inserted into the lock 31, so that the transparent door 13 rotates on the door frame 12 via the rotating rod 23. The rotating rod 23 drives the first equal diameter bevel gear 22 to rotate, and the first equal diameter bevel gear 22 drives the second equal diameter bevel gear 3003 to rotate.

[0035] Working principle: When an error occurs in the coordination of equipment in the multi-axis linkage machine tool body 10, the key is inserted into the lock 31, causing the transparent door 13 to rotate on the door frame 12 via the rotating rod 23. The rotating rod 23 drives the first equal diameter bevel gear 22 to rotate, which in turn drives the second equal diameter bevel gear 3003 to rotate. This causes the two external threads on the double threaded screw 3002 to rotate on the movable block 3004, which in turn moves on the guide rod 3001. Under the action of the adjusting rod 3012, the traction block 3010 drives the traction rod 3008 to move on the connecting block 3007. The traction block 3010 then drives the pressing rod 3013 to press the switch button 21 on the control switch 20, causing the equipment in the multi-axis linkage machine tool body 10 to stop operating. This prevents workers from being injured while operating the machine tool and improves worker safety.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
