Detailed Description

The technical solution of the present invention is further described in detail through the following embodiments.

As shown in fig. 1-3, an indexable circular insert system includes an insert holder 1, a hold-down plate 2, a hold-down plate screw 3, a circular insert 4, a circular shim 5, an indexing shaft 9, and a spring pin 10.

The front end of cutter arbor 1 is provided with and is used for the installation the blade mounting groove 6 of blade 4, gasket 5 set up in the bottom of blade mounting groove 6 is rotatable, the lower terminal surface of blade 4 is provided with positioning groove 7, be provided with the matching on the gasket 5 positioning groove 7's boss 8.

The pressing plate screw 3 is in threaded fit with the cutter bar 1, and the pressing plate 2 is pressed on the upper end face of the blade 4 downwards through the pressing plate screw 3.

The front end of the cutter bar 1 is provided with a turning hole corresponding to the turning shaft 9, the top end of the turning shaft 9 is fixed with the center of the bottom end of the gasket through threads, the middle or the bottom end of the turning shaft 9 is provided with locking grooves 11 distributed at equal angles, the cutter bar 1 is provided with mounting holes corresponding to the spring pins 10, the spring pins 10 are matched with the locking grooves 11 and used for locking the turning shaft, and the bottom end of the turning shaft 9 is provided with a turning operation handle 12.

In a preferred embodiment, the locking groove 11 is a circle of long grooves extending axially along the indexing shaft and distributed circumferentially, the top of the spring pin 10 fits in the notches of the long grooves to lock the indexing shaft, and the number of the long grooves on the indexing shaft 9 is 4-20, which can be determined according to the actual cutting depth.

In other embodiments, the boss is a cylindrical boss and the positioning groove is a cylindrical groove.

In other embodiments, the upper end surface of the blade is also provided with a positioning groove, so that the blade can be turned over for use, and the utilization efficiency is further improved.

In other embodiments, at least two positioning grooves are respectively arranged on the upper end surface or the lower end surface of the blade, and the blade is further fastened through the matching of a plurality of bosses and the positioning grooves.

In other embodiments, a pressure plate boss matched with the positioning groove is arranged below the pressure plate, and the upper end and the lower end of the blade are pressed and circumferentially locked together by matching the pressure plate with the boss and a gasket, so that the blade is prevented from shaking and sliding.

The working principle is as follows:

when the indexing operation is needed, the pressing plate 2 is loosened, the spring pin 10 is pulled up, the indexing shaft 9 and the blade 4 are both released, then the indexing shaft 9 is rotated, the indexing shaft 9 and the gasket 5 are fixed, and the gasket 5 is locked with the blade 4 through the boss 8, so that the blade 4 rotates along with the indexing shaft, the rotating angle is determined through the locking groove 11 on the indexing shaft 9, the angle of rotating through one locking groove 11 is fixed, therefore, after the specific number of locking grooves 11 are rotated, the spring pin 10 is returned to the position, the indexing shaft 9 is locked, the specific angle is adjusted, the pressing plate 2 is pressed and fixed, and the indexing and fixing of the blade are realized.

Because the circular blade uses about the terminal surface, so the terminal surface is all relatively more smooth from top to bottom, only compresses tightly the blade through the clamp plate and is difficult to realize the fixed of blade, takes place to rock and slide easily, consequently, opens positioning groove 7 on the circular blade, opens the boss on gasket 5, and both cooperations can prevent effectively that the blade from taking place to slide and rock, solve the unable fixed firm problem of blade.

It should be finally noted that the above examples are only intended to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the technical solution of the present invention, the present invention should be covered by the technical solution of the present invention.
