Description

Technical Field

[0001] The utility model relates to the technical field of numerical control lathes, and particularly relates to a protective device for numerical control lathe processing. Background Technique

[0002] The numerical control lathe is one of the numerical control lathes that are widely used at present. It is mainly used for the cutting processing of the inner and outer cylindrical surfaces of shaft parts or disc parts, the inner and outer conical surfaces with any taper angle, as well as miscellaneous rotating inner and outer curved surfaces, cylindrical and conical threads, etc. When the existing numerical control lathe processes workpieces, in order to prevent chips from flying and coolant from splashing, a protective door is generally slidably arranged on the front side of the numerical control lathe for protection. An observation window is arranged on the protective door to facilitate viewing the internal processing situation. Therefore, the observation window will be wiped and cleaned regularly. However, the observation window is generally fixedly arranged on the protective door. Therefore, when wiping the inside of the observation window, one can only reach in or drill into the numerical control lathe from one side of the protective door for wiping. The operation is rather troublesome and there is a certain danger. Content of the Utility Model

[0003] The utility model aims to solve at least one of the problems existing in the related art to a certain extent. For this reason, the utility model provides a protective device for numerical control lathe processing.

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] A protective device for numerical control lathe processing includes a numerical control lathe body, a protective door slidably arranged on the front side of the numerical control lathe body, an observation window and a handle arranged on the protective door. A rectangular opening is arranged on the front side of the protective door. A rectangular frame that can close or open the rectangular opening is hinged and flipped in the rectangular opening. The observation window and the handle are both arranged on the rectangular frame. A locking mechanism is further arranged on the rectangular frame. The locking mechanism can lock the rectangular frame so that the rectangular frame remains in the state of closing the rectangular opening.

[0006] In some embodiments, one side of the rectangular frame is installed on the rectangular opening through a hinge hinge, and the handle is arranged on the side away from the hinge hinge.

[0018] The following specific implementation details provide various different embodiments or examples for implementing the present utility model. Of course, these are only embodiments or examples and are not intended to be restrictive. Additionally, repeated reference numerals may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the present utility model and do not represent a specific relationship between the different embodiments and / or structures being discussed.

[0019] As Figures 1 - 4 shown, a protective device for CNC lathe machining includes a CNC lathe body 1, a protective door 2 slidably disposed on the front side of the CNC lathe body 1, and an observation window 3 and a handle 4 disposed on the protective door 2. A rectangular opening 5 is provided on the front side of the protective door 2. A rectangular frame 6 that can close or open the rectangular opening 5 is hingedly mounted within the rectangular opening 5 for flipping. The observation window 3 and the handle 4 are both disposed on the rectangular frame 6. A locking mechanism is further provided on the rectangular frame 6, and the locking mechanism can lock the rectangular frame 6 to keep the rectangular frame 6 in a state of closing the rectangular opening 5.

[0020] In the present utility model, by providing a rectangular opening 5 on the protective door 2, a rectangular frame 6 that can close or open the rectangular opening 5 is hingedly mounted within the rectangular opening 5 for flipping. The observation window 3 and the handle 4 are both disposed on the rectangular frame 6. That is to say, by opening the rectangular frame 6 and flipping it outwards, it is convenient to wipe the observation window 3 on the rectangular frame 6 without reaching in or drilling into the CNC lathe, thereby improving safety. Additionally, a locking mechanism is further provided on the rectangular frame 6, and the locking mechanism can lock the rectangular frame 6 to keep the rectangular frame 6 in a state of closing the rectangular opening, thereby improving the stability when the rectangular frame 6 is closed and preventing the rectangular frame 6 from accidentally opening.

[0021] It is worth mentioning that the handle 4 is disposed on the rectangular frame 6. Thus, when the locking mechanism locks the rectangular frame 6, the handle 4 can be pulled to slide on the protective door 2. When the locking mechanism unlocks the rectangular frame 6, the handle 4 can flip out the rectangular frame 6 to open the rectangular opening 5, thereby improving the practicality of the handle 4.

[0022] Furthermore, a flange 71 is provided on the inner edge of the rectangular opening 5. When the rectangular frame 6 closes the rectangular opening 5, the rectangular frame 6 abuts against the flange 71.

[0023] See Figure 1 、 Figure 2 shown, one side of the rectangular frame 6 is mounted on the rectangular opening 5 through a hinge 21. The handle 4 is disposed on the side away from the hinge 21. Due to the effect of the hinge 21, the rectangular frame 6 can be flipped open and closed.

[0024] See Figure 3, Figure 4 As shown, the handle 4 includes a mounting plate 31, a rotating shaft 32 provided at the lower end of the mounting plate 31, and a handgrip portion 33 provided at the upper end of the mounting plate 31. The rotating shaft 32 is rotatably mounted on the rectangular frame 6.

[0025] Further, the locking mechanism includes a hook 41 provided on the rotating shaft 32 and located inside the rectangular frame 6. A positioning post 42 is provided inside the protective door 2. The hook 41 can be clamped on the positioning post 42 following the rotation of the rotating shaft 32. During operation, the worker holds the handgrip portion 33 and then directly rotates. Through the rotation of the rotating shaft 32, the hook 41 is driven to be clamped on the positioning post 42 to achieve the locking of the rectangular frame 6. Similarly, when the rotating shaft 32 rotates in the opposite direction, the hook 41 is disengaged from the positioning post 42, and at the same time, the hook 41 turns into the rectangular opening 5, so that the rectangular frame 6 can be turned outwards.

[0026] See Figure 3 , Figure 4 As shown, an elastic positioning component is further provided on the rotating shaft 32. The elastic positioning component positions the rotating shaft 32, so that the hook 41 is kept in a state of being clamped on the positioning post 42, or the hook 41 is kept in a state of being disengaged from the positioning post 42.

[0027] Further, the elastic positioning component includes an extension seat 61 provided on the rotating shaft 32 and located inside the rectangular frame 6. A round hole 62 is provided on one side of the extension seat 61 close to the rectangular frame 6. A spring 63 and a positioning steel ball 64 are provided in the round hole 62. Two positioning grooves 65 are provided inside the rectangular frame 6. The two positioning grooves 65 are arranged at a 90° rotation interval with the rotating shaft 32 as the center. An arc-shaped connecting groove 66 is connected between the two positioning grooves 65. The positioning steel ball 64 is kept in a state of abutting against one of the positioning grooves 65 by the elastic force of the spring 63, so as to position the extension seat 61 and the rotating shaft 32. During switching, through the rotation of the rotating shaft 32, the positioning steel ball 64 is driven to move along the arc-shaped connecting groove 66, so that the positioning steel ball 64 moves into the other positioning groove 65, and the extension seat 61 and the rotating shaft 32 are positioned again, realizing that the hook 41 is kept in a state of being clamped on the positioning post 42, or the hook 41 is kept in a state of being disengaged from the positioning post 42.
