Description

Technical Field

[0001] The utility model relates to a protective cover body, in particular to a protective cover body for numerical control machining, belonging to the technical field of numerical control machining. Background Technique

[0002] In order to improve the safety during numerical control machining, a protective cover body is usually arranged on the top of a numerical control machine tool to protect the operators and reduce the incidence of safety accidents. In the prior art, for example, a safety protective cover for a numerical control machining center disclosed in the utility model with the application number 202320962503.1 solves the problem that the protective cover is fixed to the front end of the numerical control machining center body through support legs, resulting in difficulty in disassembling the protective cover for cleaning. By pressing down the sliding plate, the protective cover slides in the chute at the upper end of the lathe base. That is, when the lathe is working, it protects the staff. When disassembling the protective cover, after pressing down the sliding plate, the protective cover can be pulled out from the chute, making the disassembly and assembly of the protective cover very convenient and facilitating reinstallation after cleaning. A slidable protective door is connected to the front end of the outer side of the protective cover. When the lathe is working, the protective door can be closed by inserting the plug rod into the jack to protect the staff. After the lathe work is completed, the plug rod is pulled out and the protective door is opened to take out the processed workpiece, thus facilitating the use by the staff.

[0003] The similar applications currently still have deficiencies:

[0004] When opening and closing the protective door, although the protective door is slidably connected to the protective cover, a relatively large initial kinetic energy is still required, resulting in difficulty in opening and closing.

Detailed Embodiments

[0023] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below in conjunction with embodiments and drawings. However, the implementation manners of the present utility model are not limited thereto.

[0024] As Figures 1 - 4 shown, this embodiment provides a protective cover for numerical control machining, including a protective cover 1, an operation opening 2 opened on the side of the protective cover 1, and a protective door 3 covering the operation opening 2 and sliding along the length direction of the protective cover 1. Vertical plates 4 are fixed at both ends of the protective cover 1 near the operation opening 2, and buffer mechanisms 5 are provided on the sides of the vertical plates 4 close to the protective door 3. Positioning mechanisms are provided between both sides of the protective door 3 and the vertical plates 4.

[0025] Overall working principle: During installation, the protective cover 1 is fixed on the numerical control machine tool. The staff takes the workpiece from the operation opening 2. After the workpiece is placed on the numerical control machine tool, the protective door 3 is pushed to block the operation opening 2, and during the closing process, the buffer mechanism 5 is used for buffer protection, and then the positioning mechanism is used for position locking. When the workpiece is taken out, the protective door 3 is moved in a direction away from the operation opening 2, and after moving to the end of the protective cover 1, the positioning mechanism is used for locking again.

[0026] In this embodiment, the buffer mechanism 5 includes an installation groove 14, a fitting plate 15, and a buffer spring 16. The installation groove 14 is vertically opened on the side of the vertical plate 4 close to the protective door 3. Fitting plates 15 are slidably arranged inside the installation groove 14, and the fitting plates 15 protrude to the outside of the vertical plate 4. Buffer springs 16 are provided between the inner ends of the fitting plates 15 and the installation groove 14.

[0027] Local working principle: During the sliding process of the protective door 3, the side of the protective door 3 will contact the fitting plate 15 and compress the buffer spring 16, and the buffer spring 16 is used to reduce the inertial impact force when the protective door 3 moves.

[0028] In this embodiment, the fitting plate 15 is rectangular in shape, and rubber pads are provided on the sides of the fitting plate 15 close to the protective door 3.

[0029] Local working principle: Due to the setting of the rubber pads on the side of the fitting plate 15, the soft contact between the fitting plate 15 and the protective door 3 improves the buffer effect.

[0030] In this embodiment, the positioning mechanism includes a lock catch 7, a slot 8, a trapezoidal lock block 9, and a moving component. Lock catches 7 are fixed at the bottoms of the vertical plates 4 on the sides close to the protective door 3. Slots 8 matching the lock catches 7 are opened at the bottoms of both sides of the protective door 3. The depth of the slot 8 is the same as the protruding length of the lock catch 7. Trapezoidal lock blocks 9 are slidably arranged at the inner tops of the slots 8. A moving component for controlling the vertical sliding of the trapezoidal lock block 9 is provided on the protective door 3.

[0031] Local working principle: During the movement of the protective door 3, when using the buffer spring 16 to reduce vibration, the inertial force during the movement of the protective door 3 is converted into elastic potential energy. The lock catch 7 will insert into the inside of the slot 8, and the lock catch 7 will contact the inclined surface of the trapezoidal lock block 9 and control the trapezoidal lock block 9 to slide upward. After the buffer spring 16 reaches the maximum compression amount, at this time, the fitting plate 15 hides inside the installation groove 14, the protective door 3 fits with the vertical plate 4, and at the same time, the trapezoidal lock block 9 inserts into the lock catch 7, the position of the protective door 3 is fixed, and the elastic potential energy of the buffer spring 16 is stored. When unlocking the protective door 3, at this time, the buffer spring 16 resets, providing initial kinetic energy to the protective door 3, which facilitates the movement of the protective door 3.

[0032] In this embodiment, a door handle 6 is provided at one end of the outer side of the protective door 3 close to the operation port 2, and the shape of the door handle 6 is U-shaped.

[0033] Local working principle: When controlling the movement of the protective door 3, holding the door handle 6 makes the movement of the protective door 3 more labor-saving.

[0034] In this embodiment, the moving mechanism includes a pull rope 10, a sliding groove 11, a return spring 12 and a slider 13. The sliding groove 11 is opened inside the door handle 6, a slider 13 is slidably arranged inside the sliding groove 11, a return spring 12 is provided between the slider 13 and the inner end of the sliding groove 11, a pull rope 10 is fixed to the top of the trapezoidal lock block 9, and the pull rope 10 slides out through the inside of the protective door 3 and the door handle 6 and is fixedly connected to the slider 13.

[0035] Local working principle: In the initial state, the slider 13 protrudes outside the sliding groove 11. At this time, the trapezoidal lock block 9 is in the reset state, and the bottom end of the trapezoidal lock block 9 fits with the inner bottom of the slot 8. If it is necessary to unlock the protective door 3, press the slider 13 with a finger, the slider 13 will move into the sliding groove 11, and will pull the pull rope 10, thereby sliding the trapezoidal lock block 9 upward to unlock the protective door 3.

[0036] In this embodiment, a transparent window 17 is opened on the protective door 3, a brush plate 18 is vertically provided on the side of the operation port 2, and the brush plate 18 fits on the inner side of the transparent window 17.

[0037] Local working principle: The processing condition can be observed through the transparent window 17, and the use of the brush plate 18 can automatically wipe and clean the transparent window 17 during the sliding process of the protective door 3.

[0038] As described above, it is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and its concept of the present utility model, makes equivalent replacements or changes, and all belong to the protection scope of the present utility model.
