Problems solved by technology

The method of adding pins requires additional processes and costs. In addition, the displacement of the process boss can be reduced to a certain extent by adding a compression washer. However, if the installation is not in place and the deviation between the center of the nut and the center of the screw is too large, it will still cause compression. Insufficient tightening force, the problem of rotation of the process boss occurs

Embodiment 1

[0030] The present invention is realized through the following technical solutions, as Figure 1-Figure 3 As shown, a method for stopping and compressing the process boss 8 is to select the compression screw according to the position and size of the process boss 8 of the part 6, and to process one on the process boss 8 and the tooling 5 to form a plane with the tooling 5. Stepped through holes with an included angle α, the small ends of the two stepped through holes are connected to form a compression screw hole for installing a compression screw; install and tighten the tightening screw in the compression screw hole, so that the tooling 5 and the part 6 are close .

[0031] It should be noted that, through the above improvements, fixing the process boss 8 of the part 6 by using the pressing screw with an inclination angle can increase the radius of action of the pressing force, increase the moment under the same pressing force, and help reduce the process boss 8 The amount o...

Embodiment 2

[0034] This embodiment is further optimized on the basis of the above-mentioned embodiments such as figure 1 As shown, further, in order to better realize the present invention, the following steps are specifically included:

[0035] Step S1: According to the structural characteristics of the process boss 8 and the tooling 5, and the positions of the cut-in end 4 and the cut-out end 3 when the process boss 8 is removed, determine the screw inclination direction, set the screw inclination angle α, and calculate the corresponding screw length L;

[0036] Step S2: Determine the axis in the longitudinal direction of the compression screw hole according to the bottom plane profile of the process boss 8 and the screw inclination angle; the axis in the longitudinal direction is parallel to the side of the tooling 5 .

[0037] Step S3: Select an appropriate screw diameter specification according to the width of the process boss 8 and the processing stability requirements, and determi...

Embodiment 3

[0043] This embodiment is further optimized on the basis of the above embodiments, such as figure 1 As shown, further, in order to better realize the present invention, the direction of inclination of the screw is that the side of the screw away from the tooling 5 is inclined toward the cutting end 3, and the inclination angle α<90°.

[0044] Further, in order to better realize the present invention, the length of the tooling 5 along the axial direction of the longitudinal direction of the compression screw is H2, and the length of the process boss 8 along the axial direction of the longitudinal direction of the compression screw is H1; The length of the screw rod 2 in the screw is L, and said L

[0045] It should be noted that, through the above improvement, the adoption of the above method even effectively ensures that the length of the screw is always thinner than the thickness of the process boss 8 and the thickness of the tooling 5 . Effectively prevent the s...

Abstract

The invention discloses a method for locking and pressing a false boss. A pressing screw is selected according to the position and the size of the false boss, stepped through holes are machined in thefalse boss and a tool, included angles alpha are formed between the stepped through holes and a tool plane, and the small ends of the two stepped through holes communicate to form a pressing screw hole for mounting of the pressing screw. The pressing screw is mounted and screwed in the pressing screw hole, so that the tool and a part are attached. The method has the beneficial effects that the situation that the false boss rotates when the false boss is removed through numerical control machining of the part can be effectively avoided, the method can also be used for large-allowance fixation,the pressing reliability is improved, and the part is prevented from being scratched.

Description

technical field [0001] The invention relates to the technical field of numerical control machining, in particular to a method for stopping and pressing a process boss. Background technique [0002] With the continuous optimization and improvement of modern design methods and processing methods, various parts are gradually developing in the direction of large-scale, complex and integrated, the processing cycle is shortening day by day, and the requirements for processing quality are gradually increasing. In order to improve the processing efficiency of parts, at this stage, aluminum alloy, titanium alloy and stainless steel parts are mostly processed by CNC machining, and process bosses are added to the parts to fix and align the parts. With the gradual increase in the number of process bosses of parts, in order to improve the processing efficiency of parts, it is usually required to remove most of the process bosses in the process of CNC machining. [0003] The process boss...
