Description

Technical Field

[0001] The utility model relates to the technical field of machine tool grating protection, in particular to a machine tool grating protection device. Background Art

[0002] The grating of the machining center includes a grating scale and a reading head slidably mounted on the grating scale. The grating is a measurement feedback device that works on optical principles. Its measurement output signal is a digital pulse, which has the characteristics of large detection range, high detection accuracy and fast response speed.

[0003] After the grating is installed, a large amount of iron filings will be generated during the operation of the machining center. In order to prevent iron filings and other impurities from splashing into the grating and causing damage to the grating, a protective shell is currently installed on the outside of the grating to block the entry of iron filings, and the iron filings will adhere to the surface of the protective shell. When the grating needs to be disassembled for maintenance, the protective shell needs to be removed first. Generally, it is necessary to clean and scrape off the iron filings and other impurities on the surface of the protective shell before removing the protective shell. However, in actual operation, workers may forget to clean or clean it insufficiently, resulting in iron filings falling onto the grating when the protective shell is removed. There is a risk of impurities entering the grating, which is not conducive to protecting the grating. Utility Model Content

[0030] See also Figure 1 and Figure 2The mounting frame 1 is placed outside the grating and mounted on the machine tool. Specifically, a plurality of mounting plates 14 are arranged outside the mounting frame 1. The mounting plates 14 are provided with screw holes. The mounting frame 1 can be fixed by inserting bolts into the screw holes and fixing them on the corresponding mounting holes of the machine tool. A plug-in ring groove 11 is provided on the front side of the mounting frame 1. The plug-in ring groove 11 is extended along the front edge of the mounting frame 1, and a plurality of slots 12 that are connected with the plug-in ring groove 11 are provided on the top of the mounting frame 1. Each slot 12 is arranged linearly along the length direction of the mounting frame 1. A lock column 13 is movably inserted in each slot 12, and the lock column 13 can stop moving in the slot 12 when no external force is applied. Preferably, the outer side of the lock column 13 has a rubber layer to increase the friction between the lock column 13 and the inner wall of the slot 12, and further prevent the lock column 13 from falling due to gravity when no external force is applied, while ensuring the sliding ability of the lock column 13. An abutting cone head 131 is disposed at the front side of the top end of the locking column 13 , and a gap is left between the bottom side of the abutting cone head 131 and the top wall of the mounting frame 1 .

[0031] The rear side of the shell 2 is open and the edge of its rear side can be movably inserted into the plug-in ring groove 11. The plug-in ring groove 11 is adapted to the size of the rear edge of the shell 2. A plurality of lock holes 21 are provided on the top of the shell 2 corresponding to each slot 12. When the rear edge of the shell 2 is inserted into the bottom of the plug-in ring groove 11, each lock hole 21 will be located below its corresponding slot 12. A slide bar 22 is laterally provided on the front side of the shell 2.
