Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a protection mechanism for numerical control machine tools. Background Art

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. It can move the machine and process parts according to the programmed program. It integrates mechanical, automation, computer, microelectronics and other technologies to solve the processing problems of complex, precise and small batch parts. It is a flexible and high-efficiency automated machine tool. When using a CNC machine tool, a CNC machine tool protection mechanism is needed.

[0003] Most of the current CNC machine tools do not have an effective protective structure, which will result in that when objects in the external environment collide with the machine tool, the impact force caused by the impact will cause damage to the machine tool, thereby affecting the normal use of the machine tool, and the current machine tools cannot effectively fix the position of the protective door. This will cause the protective door to be displaced when the staff needs to inspect and repair the inside of the machine tool, which will cause the staff to be squeezed by the protective door, which will affect the health of the staff. Moreover, during the operation of the machine tool, vibrations will be generated. At this time, if the protective door cannot be effectively fixed, the force generated by the vibration will also cause the protective door to be displaced, which will cause the parts and debris inside the machine tool to splash, etc., which will not only pollute the environment but also cause harm to the staff.

[0004] Therefore, those skilled in the art provide a CNC machine tool protection mechanism to solve the problems raised in the above background technology. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 - Figure 7 As shown, this embodiment provides a CNC machine tool protection mechanism, including a machine tool body 1, and also includes:

[0027] The mounting frame 2 is fixedly connected to the front end surface of the machine tool body 1. Visual protection doors 3 are symmetrically arranged inside the mounting frame 2. The front end surfaces of the two visual protection doors 3 are fixedly connected with handles.

[0028] A fixing assembly is arranged in front of the two visual protection doors 3 and is used to fix the positions of the visual protection doors 3, so as to facilitate the staff to inspect and repair the inside of the machine tool body 1, and at the same time prevent the visual protection door 3 from opening due to vibration generated during the operation of the machine tool body 1;

[0029] The protective components are symmetrically arranged on both sides of the outer wall of the machine tool body 1 and are used to protect the machine tool body 1, so as to prevent objects in the external environment from impacting the machine tool body 1 and causing damage to the machine tool body 1.

[0030] The above working principle: when it is necessary to fix the position of the visual protection door 3, the position of the visual protection door 3 can be fixed conveniently and effectively by only using the fixing component, thereby preventing the visual protection door 3 from being displaced when the staff is inspecting and repairing the inside of the machine tool body 1, causing injuries to the staff. At the same time, it can effectively prevent the vibration generated during the operation of the machine tool body 1 from causing the displacement of the visual protection door 3, effectively improving the safety factor of the machine tool body 1 during use. When objects in the external environment accidentally collide with the machine tool body 1, the protection component can effectively buffer the impact force generated by the collision, thereby effectively protecting the machine tool body 1, effectively extending the service life of the machine tool body 1, saving time and effort.

[0031] In order to effectively improve the stability of the visual protection door 3 during the movement, a plurality of connecting blocks 4 are fixedly connected to the front end surface of the mounting frame 2, and a guide rod 5 is fixedly connected between every two connecting blocks 4. The front end surfaces of the two visual protection doors 3 are symmetrically provided with fixing plates 6, and the outsides of the plurality of fixing plates 6 are fixedly connected with guide blocks 7. The insides of the plurality of guide blocks 7 are provided with guide grooves for the guide rods 5 to move. During the movement of the visual protection door 3, the fixing plates 6 will be driven to move synchronously, and the fixing plates 6 will then drive the guide blocks 7 to move synchronously outside the guide rods 5. At this time, the stability of the visual protection door 3 during the movement can be improved through the cooperation between the guide rods 5 and the guide blocks 7.

[0032] Considering that the position of the visual protection door 3 needs to be fixed after the visual protection door 3 is opened or closed, the fixing component includes a fixing block 8 fixedly connected to the front end surface of the plurality of guide blocks 7, a fixing rod 19 is arranged inside the fixing block 8, one end of each of the two fixing rods 19 extends to the outside of the fixing block 8 and is fixedly connected with a pull plate, a resistance plate 20 is fixedly connected to the outside of the fixing rod 19, a return spring 21 is sleeved on the outside of the fixing rod 19, the return spring 21 is in contact between the resistance plate 20 and the fixing block 8, the contact surfaces of the plurality of fixing blocks 8 and the guide blocks 7 are provided with guide grooves for the movement of the fixing rods 19, and guide grooves for the movement of the fixing rods 19 are evenly spaced inside the two guide rods 5, when the visual protection door 3 needs to be opened or closed. , you only need to pull the pull plate first, at this time the pull plate will drive the fixed rod 19 to move synchronously, and the fixed rod 19 will drive the contact plate 20 to move synchronously. During the movement of the contact plate 20, the reset spring 21 will be squeezed. When the fixed rod 19 is out of the guide groove inside the guide rod 5, pull the handle again. At this time, the handle will drive the visual protection door 3 to move synchronously. When the visual protection door 3 moves to the required position, release the pull plate again. At this time, the reset spring 21 is reset, driving the contact plate 20 and the fixed rod 19 to move synchronously. When the fixed rod 19 is inserted into the guide groove inside the guide rod 5, the position of the visual protection door 3 can be fixed. At this time, the visual protection door 3 can be prevented from being displaced, etc., effectively improving the safety factor of the machine tool body 1.

[0033] In order to further improve the smoothness of the visual protection door 3 during movement, movable wheels 18 are symmetrically provided on the upper and lower surfaces of the two visual protection doors 3. During the movement of the visual protection door 3, the movable wheels 18 will also be driven to move synchronously. At this time, the movable wheels 18 can effectively improve the smoothness of the visual protection door 3 during movement.

[0034] In order to effectively protect the machine tool body 1, the protection component includes a buffer plate 12 symmetrically arranged on both sides of the outer wall of the machine tool body 1, a buffer rod 13 is fixedly connected inside the buffer plate 12, and a slider 14 is symmetrically arranged outside the buffer rod 13. A guide groove for the slider 14 to move is opened outside the buffer plate 12, and a buffer spring 15 is sleeved outside the buffer rod 13. The two ends of the buffer spring 15 are respectively fixedly connected to the opposite sides of the two sliders 14. The interior of each two sliders 14 is hinged with a hinge block 17 through a connecting rod 16, and the outside of each two hinge blocks 17 is fixedly connected to a protective plate 9. Damping rods 11 are symmetrically arranged on both sides of the outer wall of the machine tool body 1, and the telescopic ends of multiple damping rods 11 are fixedly connected to the outside of the protective plate 9. When objects in the external environment accidentally hit the machine tool body 1 The impact force generated by the collision will cause the protective plate 9 to be displaced, and the protective plate 9 will then drive the hinge block 17 to move synchronously. Since the slider 14 and the hinge block 17 are hinged by the connecting rod 16, the hinge block 17 will drive the slider 14 to move synchronously outside the buffer rod 13 through the connecting rod 16. During the movement of the slider 14, the buffer spring 15 will be stretched. At this time, the buffer spring 15 can effectively buffer the impact force generated by the collision, thereby effectively protecting the machine tool body 1, and further effectively extending the service life of the machine tool body 1. Through the setting of the damping rod 11, the elastic potential energy of the buffer spring 15 can be effectively limited, thereby preventing the buffer spring 15 from repeatedly rebounding, etc., which affects the buffering effect of the buffer spring 15.

[0035] In addition, in order to effectively protect the buffer spring 15 and other components from dust, accordion protective covers 10 are fixedly connected to both sides of the outer wall of the machine tool body 1, and the other ends of the two accordion protective covers 10 are respectively fixedly connected to the opposite sides of the two protective plates 9. Through the setting of the accordion protective covers 10, the buffer spring 15 and other components can be effectively protected from dust, thereby effectively extending the service life of the buffer spring 15 and other components, and at the same time will not cause any impact on the normal use of the buffer spring 15 and other components.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
