Embodiment 1

[0044] A kind of tooling for CNC machining of six-sided parts, including a tooling base and a tooling pressing mechanism, the tooling base includes a tooling support frame 6 and a part installation positioning plate 4 arranged on the top of the tooling support frame 6; the part installation positioning plate 4 The top is provided with a transverse T-shaped slot 2, and the bottom of the tooling pressing mechanism is installed in the T-shaped slot 2; the tooling support frame 6 is provided with a knife inspection block placement hole 5 for installing a knife inspection block.

[0045] During the use of the present invention, the numerical control machining of the six-sided part 21 is realized through the following steps:

[0046] Step 1: Place the six-sided part 21 on the part installation positioning plate 4, and fix the six-sided part 21 on the tooling;

[0047] Step 2: Install the knife inspection block in the hole 5 of the knife inspection block;

[0048] Step 3: Carry out ...

Embodiment 2

[0059] This embodiment is further optimized on the basis of Embodiment 1. The part mounting positioning plate 4 is provided with mounting screw holes 3, and the screws pass through the mounting screw holes 3 from the bottom of the mounting positioning plate reversely to connect the six-sided parts 21.

[0060] During the use of the present invention, through the setting of the mounting screw holes 3, four clamping holes can be prepared on the side with more blank margins of the six-sided machined parts before the installation of the six-sided parts 21, and the clamping holes Internal tapping thread, the diameter of the pressing hole is the same as that of the mounting screw hole 3; place the side with the pressing hole on the positioning plate of the tooling, and use screws to tighten the screws from the bottom of the mounting screw hole 3 upwards, and the tooling and the blank fixed.

[0061] In the present invention, through the setting of the mounting screw hole 3, by tight...

Embodiment 3

[0064] This embodiment is further optimized on the basis of Embodiment 2. The tooling pressing mechanism includes a nut 10, an adjustable screw 14, a screw washer 11, and a pressing plate. The adjustable screw 14 is installed in the T-shaped groove 2, and A pressure plate is installed on the adjustable screw 14 , the top of the adjustable screw 14 passes through the pressure plate and is connected with the nut 10 , and a screw washer 11 is arranged between the pressure plate and the nut 10 .

[0065] During the use of the present invention, when performing the second clamping, the adjustable screw rod 14 is first installed in the T-shaped groove 2, and the bottom of the adjustable screw rod 14 is determined to be in the T-shaped groove 2 according to the position of the six-sided part 21. Then clamp the processed surface of the six-sided part 21, put the six-sided part 21 on the part mounting plate, pass the pressure plate and the screw washer 11 into the adjustable screw rod 1...

Abstract

The invention discloses a six-surface part numerical control machining tool. The six-surface part numerical control machining tool comprises a tool base and a tool pressing mechanism; the tool base comprises a tool support frame, and a part mounting positioning plate arranged at the top of the tool support frame; a transverse T-shaped groove is formed in the top of the part mounting positioning plate; the bottom of the tool pressing mechanism is mounted in the T-shaped groove; and the tool support frame is provided with a cutter checking block placing hole for mounting a cutter checking block.Through arrangement of the machining tool, the need of multiple tools for multiple times of clamping in the six-surface part machining is solved, the machining of six-surface parts is realized through twice clamping, errors caused by multiple times of clamping are reduced, the machining quality of the parts is improved, and the machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of tooling for processing six-sided parts, and in particular relates to a tooling for CNC machining of six-sided parts. Background technique [0002] With the development trend of large-scale and integrated aircraft structural parts, there are more and more complex and multi-faceted parts, and at the same time, the requirements for machining accuracy of parts are also getting higher and higher. These complex multi-faceted parts generally need to be processed multiple times, and after the parts are clamped many times, the accumulation of errors will lead to a large number of tool marks on the parts, which seriously affects the machining accuracy of the parts. When using traditional methods to process such parts, generally according to the characteristics of the parts, multiple special tooling is customized, and each side is processed with a special tooling, and multiple sets of special tooling are required to...
