Description

Technical Field

[0001] The utility model relates to the technical field of protective equipment for numerically controlled lathes, in particular to an integrated protective cover for numerically controlled lathes. Background Art

[0002] A CNC machine tool, short for digitally controlled machine tool, is an automated machine tool equipped with a program-controlled system. This control system logically processes programs specified by control codes or other symbolic instructions, decodes them, and transmits them to a coded digital representation via an information carrier. After computational processing, the CNC device issues various control signals, controlling the machine's movements and automatically producing parts to the shape and size specified in the drawings.

[0003] The existing CNC lathe protective covers usually adopt multi-layer superimposed and retractable movable protective covers. When in use, the protective covers completely cover the lathe processing section, which is not conducive to the staff to view and operate the lathe processing process; if a fault occurs in the processing section, the protective cover needs to be retracted to expose the fault location of the lathe before the fault maintenance can be carried out. After the maintenance is completed, the protective cover is pulled again to close it. There are many inconveniences in its operation and working process. Therefore, we propose to design an integrated protective cover for CNC lathes. Utility Model Content

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0024] See also Figure 1-4 The utility model provides an integrated protective cover for a CNC lathe, including a left slide rail 1 and a right slide rail 2. The left slide rail 1 and the right slide rail 2 are fixedly connected to a wing plate 3 on the side away from each other. A plurality of screw holes 4 are opened inside the wing plate 3. The wing plate 3 is fixed to the external CNC lathe body by bolts. The bolts pass through the screw holes 4 and are threadedly connected to the external CNC lathe body, which makes it easy to quickly connect the protective cover to the lathe to be assembled and used.

[0025] A left guard 5 and a right guard 6 are respectively provided at the two ends of the top of the left slide rail 1 and the right slide rail 2. A movable door 9 is rotatably connected to the inside of the ends of the left guard 5 and the right guard 6 away from each other. The top of the movable door 9 is connected to the left guard 5 and the right guard 6 by a spring hinge, which is convenient for closing the ends of the guards. The end away from the lathe control end is the open end. For this end, it is convenient to flexibly open the movable door 9 corresponding to this end to perform operations such as taking out items.

[0026] Locking assemblies 11 are provided at both ends of the outer sides of the left guard 5 and the right guard 6, wherein the locking assembly 11 includes a limit frame 111 fixed to the ends of the left guard 5 and the right guard 6, and a pin 112 is provided inside the limit frame 111 from top to bottom. No matter which end of the device faces the control end of the lathe, the pin 112 in that direction is inserted into the limit frame 111. At this time, the pin 112 is located outside the slide rail, which is convenient for positioning that end so that it remains fixed, while the guard at the other end can be flexibly extended and retracted.

[0027] Several inner shields 7 are arranged between the left shield 5 and the right shield 6. The several inner shields 7 are nested with each other. The shell size of the inner shield 7 decreases from the left shield 5 and the right shield 6 to the center of the two. The nested design is convenient for pulling and can flexibly control the coverage range of the shield.

[0028] The bottom of the left guard 5, the right guard 6 and several inner guards 7 are all provided with pulleys 8 corresponding to the left slide rail 1 and the right slide rail 2, so that the staff can pull the left guard 5, the right guard 6 and the inner guard 7 to move as needed.

[0029] Several observation windows 10 are located at the top of the inner shields 7. These windows 10 consist of a window frame embedded in the top of the inner shields 7. The window frame contains a tempered glass window, which is connected to the window frame via a spring hinge. When the nested portion of the inner shields 7 is fully opened, the observation windows 10 are exposed to the outside world, allowing staff to open these windows 10 and flexibly access components. When the shields are only being used in a distributed manner, care should be taken to open the entire inner shield 7 as much as possible to allow the observation windows 10 in more areas to be open, thereby improving operational flexibility.

[0030] During installation, the guard and the slide rails are installed integrally on the CNC lathe by bolts, and one end, here taking the left guard 5 as an example, the pin 112 close to the end is inserted into the limit frame 111. At this time, the pin 112 is located outside the slide rail, which is convenient for fixing the left guard 5, and the right guard 6 can be pulled flexibly at this time to facilitate adjustment of the overall coverage range of the guard.

[0031] When in use, the staff needs to pull out the entire inner shield 7 as much as possible, and the unused inner shield 7 is nested in the left shield 5 or the right shield 6. Then, during the lathe processing process, the staff can not only check the status of the parts being processed in the lathe through the tempered glass, but the tempered glass can also protect the staff to prevent the workpiece from accidentally splashing during processing. Moreover, after the processing is completed, the staff can open the observation window 10 corresponding to the position at any position on the lathe to adjust the workpiece or lathe equipment, so that the lathe can better process the workpiece. There is no need to repeatedly stretch and shrink the shield during the processing troubleshooting, which saves manpower and time and improves the operating efficiency of the staff.
