Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a cutter frame for gear machining comprises a cutter frame main body 1, wherein the cutter frame main body 1 is of a square structure, a cutter 8 is installed on the cutter frame main body 1, a first mounting seat 6 is arranged on the cutter frame main body 1, a second mounting seat 7 is arranged at the lower end of the first mounting seat 6, a groove is formed in the upper end of the second mounting seat 7, the width of the groove of the second mounting seat 7 is equal to that of a second fixing block 4, the grooves of the second mounting seat 7 are criss-cross, the groove of the second mounting seat 7 can be conveniently fixed in any square shape by criss-cross in the structure, the cutter 8 can be conveniently installed and fixed, a gasket 5 is connected to the upper end of the first mounting seat 6, the gasket 5 is made of a steel plate, the thickness of the gasket 5 is 0.3cm, the gasket 5 is fixedly connected with the first mounting seat 6 through bolts, and the 0.3cm steel plate of the gasket 5 can protect the first mounting seat 6, the abrasion to the first mounting seat 6 is avoided when an adjusting bolt at the upper end of the first mounting seat 6 rotates, the gasket 5 can be conveniently replaced after abrasion, the time spent on repairing the first mounting seat 6 is reduced, the fixing bolt 2 penetrates through the first mounting seat 6, the lower end of the fixing bolt 2 is connected with the first fixing block 3, the second fixing block 4 is arranged on the second mounting seat 7, the first fixing block 3 and the second fixing block 4 are identical in shape and size, the first fixing block 3 and the second fixing block 4 are both made of steel materials, the hardness of the steel materials of the first fixing block 3 and the second fixing block 4 is high, the wear-resistant capacity is high, the replacement can be conveniently carried out even if the steel materials are abraded, the time and energy delayed in repairing the knife rest main body 1 are avoided, the work of the knife rest main body 1 is more efficient, arc-shaped grooves which are identical in size are formed in the lower end of the first fixing block 3 and the upper end of the second fixing block 4, and square groove has still been seted up in the arc recess of first fixed block 3 and second fixed block 4, a circular port can be pieced together with the arc recess of second fixed block 4 to this structure first fixed block 3, thereby it is fixed to have made things convenient for the handle of a knife to be columniform cutter 8 installation, the square groove that still is equipped with in the arc recess of first fixed block 3 and second fixed block 4 can make things convenient for fixed handle of a knife to be square cutter 8, threaded hole is seted up to first fixed block 3 upper end, and the screw hole interval of first fixed block 3 equals with fixing bolt 2 intervals, the screw hole interval of this structure first fixed block 3 equals can conveniently fix fixing bolt 2 and first fixed block 3 through the screw hole with fixing bolt 2 intervals.
