Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-6, the utility model provides a DLC coating cutter technical scheme, which comprises a cutter handle 1, a cutter bar 2, bolts 3, an outer frame 4, a driving rod 5, a gear set 6, a bracket 7 and a guide plate 8, wherein the cutter handle 1 is provided with four groups of screw holes I11 and two groups of guide grooves 12, the cutter bar 2 is provided with two groups of screw holes II 21, and the four groups of screw holes I11 and the two groups of screw holes II 21 are respectively matched with the thread structures of the two groups of bolts 3;

After the upper part of the cutter bar 2 is arranged in the cutter bar 1, the driving bar 5 drives the two groups of bolts 3 to rotate in the same direction through the gear set 6, and then the two groups of bolts 3 penetrate through the four groups of screw holes I11 and the two groups of screw holes II 21 in a threaded manner, so that the cutter bar 1 and the cutter bar 2 are assembled and fixed, the upper part of the cutter bar 1 is arranged on a numerical control machine, and when the cutter bar 2 is required to be disassembled due to cutter head abrasion, the driving bar 5 drives the two groups of bolts 3 to rotate through the gear set 6, so that the free ends of the two groups of bolts 3 move into the two groups of screw holes I11 on one side of the outer frame 4, and then the cutter bar 2 is contacted with the cutter bar to be fixed, so that replacement is performed;
