Embodiment 1

[0044] A six-sided parts numerical control processing tooling, 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; A transverse T-shaped groove 2 is opened on the top, and the bottom of the tooling pressing mechanism is installed in the T-shaped groove 2; the tooling support frame 6 is provided with a tool inspection block placement hole 5 for installing a tool inspection block.

[0045] In the use process of the present invention, the six-sided parts 21 are CNC processed through the following steps:

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

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

[0048] Step 3: Perform tool verification through the tool inspection block;

[0049] Step 4: After checking that the...

Embodiment 2

[0059] This embodiment is further optimized on the basis of Embodiment 1. The component 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 to connect the six-sided parts 21.

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

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

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-slot 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, during the second clamping, first install the adjustable screw 14 in the T-slot 2, and determine the bottom of the adjustable screw 14 in the T-slot 2 according to the position of the six-sided parts 21 Then, clamp the machined surface of the six-sided part 21, place the six-sided part 21 on the part mounting plate, pass the pressure plate and the screw washer 11 into the adjustable screw 14 in turn, and pass the screw The cap 10 is locked, and the six-si...

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 six-sided parts processing tooling, and specifically relates to a six-sided part numerical control processing tooling. Background technique [0002] With the development trend of large-scale and integrated aircraft structural parts, there are more and more complex multi-faceted parts, and at the same time, the requirements for machining accuracy of parts are getting higher and higher. These complex multi-faceted parts generally need to be processed multiple times, and after the parts are clamped multiple times, the accumulation of errors will cause a large number of tool marks on the parts, which seriously affects the machining accuracy of the parts. When traditional methods are used to process such parts, multiple special toolings are usually customized according to the characteristics of the parts. One special tooling is used for each processing side, and multiple sets of special tooling are required to comp...
