In order to achieve the above purpose, the present utility model provides the following technical solutions:

the improved nest cutting tool comprises a nest cutting tool main body, wherein a replacement mechanism is arranged on the inner wall of the nest cutting tool main body;

the replacing mechanism comprises a blade and an inner hexagon bolt;

one side of the blade is attached to the inner wall of the nest-dividing cutter body, and the inner wall of the blade is connected with the outer wall of the inner hexagon bolt in a threaded manner.

Preferably, the outer wall of the inner hexagon bolt is in threaded connection with the inner wall of the nest-dividing cutter body.

Preferably, the top of the main body of the nest-cutting tool is fixedly connected with a bottom clamping rod.

Preferably, the top of the bottom clamping rod is fixedly connected with a round rod.

Preferably, the outer wall sliding joint of round bar has top clamping lever.

The improved nest cutting knife provided by the utility model has the beneficial effects that: through driving the hexagon socket head cap screw with the help of the hexagonal spanner and rotating, the hexagon socket head cap screw cooperates and draws the nest knife main part and fix the blade, draws the nest knife and dulled back, only need change the blade, reduced the processing cost that the work piece was drawn the nest.

FIG. 2 is an enlarged schematic view of the portion A in FIG. 1;

FIG. 3 is a schematic view of the connection structure of the bottom clamping bar, the round bar and the top clamping bar in FIG. 1;

fig. 4 is an enlarged schematic view of the portion B in fig. 1.

In the figure: 1. the cutter comprises a cutter body, 2 parts of a replacing mechanism, 201 parts of a cutter blade, 202 parts of an inner hexagon bolt, 2a1 parts of a spring, 3 parts of a bottom clamping rod, 4 parts of a top clamping rod, 5 parts of a round rod.

Detailed Description

The utility model is further described below with reference to the accompanying drawings:

referring to fig. 1-4: in the embodiment 1, an improved generation draws nest cutter, including drawing nest cutter main part 1, the inner wall of drawing nest cutter main part 1 is equipped with change mechanism 2, change mechanism 2 is convenient to change blade 201, change mechanism 2 includes blade 201 and hexagon socket head cap screw 202, one side of blade 201 is laminated with the inner wall of drawing nest cutter main part 1, draw nest cutter main part 1 spacing to blade 201, the inner wall of blade 201 and hexagon socket head cap screw 202's outer wall thread meet, blade 201 is spacing to hexagon socket head cap screw 202, hexagon socket head cap screw 202's outer wall and draw nest cutter main part 1's inner wall thread meet, draw nest cutter main part 1 to be fixed to blade 201 in cooperation with hexagon socket head cap screw 202, the top rigid coupling of drawing nest cutter main part 1 has bottom clamping lever 3, bottom clamping lever 3 drives and draws nest cutter main part 1 rotation, the top rigid coupling of bottom clamping lever 3 has round bar 5, round bar 5 drives bottom clamping lever 3 rotation, the outer wall slip joint of round bar 5 has top clamping lever 4, top clamping lever 4 drives round bar 5 rotation;

the inner hexagon bolt 202 is driven to rotate by means of the hexagon wrench, the inner hexagon bolt 202 is matched with the nest-dividing cutter body 1 to fix the cutter 201, and after the nest-dividing cutter becomes blunt, the cutter 201 only needs to be replaced, so that the processing cost of workpiece nest dividing is reduced.

Working principle:

the socket head cap screw 202 is driven to rotate by means of the hexagonal wrench, the socket head cap screw 202 is matched with the socket head cap screw body 1 to fix the blade 201, after the socket head cap screw becomes blunt, the blade 201 is only required to be replaced, machining cost of socket cutting of workpieces is reduced, the blade 201 is made of carbon tool steel, the top clamping rod 4 is fixed on the machine tool body, an external power supply of the machine tool body is connected, the machine tool body drives the socket head cap screw body 1 at the bottom to move downwards, after the socket head cap screw body 1 contacts with the workpieces to be machined, the machine tool body drives the top clamping rod 4 to rotate, the top groove part of the round rod 5 is in sliding clamping connection with the top clamping rod 4, the top clamping rod 4 drives the round rod 5 to rotate, and the round rod 5 drives the socket head cap screw body 1 at the bottom of the bottom clamping rod 3 to rotate, so that the socket head cap screw body 1 performs socket cutting on the workpieces to be machined.
