Problems solved by technology

[0002] At present, when machining high-precision hole groups (especially hole group distances exceeding 4000mm) on parts with large shapes and structures, there are usually two methods. One is the traditional method, which uses a dynamic boring bar to process hole groups. During this process, the boring bar needs to be set multiple times, which often results in inconsistent benchmarks between the holes. After the machining is completed, the position accuracy and flatness of the holes cannot meet the assembly requirements; Although this method can improve the precision of hole processing, the floor boring and milling machine has a large volume and heavy tonnage. In the actual application process, it needs to be equipped with a large space and a lifting device with sufficient lifting capacity. , which undoubtedly brings great difficulties to hole group processing

Embodiment 1

[0028] Embodiment 1: This embodiment takes eight holes to be processed on the part to be processed as an example to describe the processing method in the present invention in detail.

[0029] A processing method for realizing a hole group with high position accuracy by using tooling, comprising the following steps:

[0030] Step 1: If image 3 As shown, the part 7 to be processed needs to process eight holes at a certain position, so according to the distribution shape required by these eight holes, it is made as figure 1 As shown in the boring tooling 1, the external dimensions of the boring tooling 1 mainly depend on the distribution of the eight holes to be processed on the part 7 to be processed, and the outer contour of the boring tooling 1 is not limited to figure 1 The octagon shown can also be geometric shapes such as a circle, an ellipse, and a triangle, as long as the boring tooling 1 can cover the hole group of the part to be processed;

[0031] Step 2: If figure...

Embodiment 2

[0036] Embodiment 2: In the step 2, the jacking block 4 is arranged on the outer circumference of the boring tool 1, and the number of the jacking block 4 is not fixed, and its number depends on the number of screw jackscrews on the part 7 to be processed . It should be noted that whether the jacking block 4 is arranged inside or outside the boring tool 1 depends on the processing space around the part 7 to be processed.

[0037] In addition, the power boring bar 9 can be single or multiple. When the power boring bar 9 is single, it is necessary to use the power boring bar 9 to separately process each hole of the hole group forming the part 7 to be processed. When there are multiple dynamic boring bars 9, each hole forming the hole group of the part to be machined 7 can be machined in groups. The quantity of the dynamic boring bar 9 can be adjusted according to the distribution space and needs of the hole groups on the part to be processed.

Abstract

The invention discloses a method for machining a high position precision hole group by a tool. The method includes the steps: manufacturing a boring die tool according to the distribution shape of the hole group in a part to be machined; arranging a plurality of jacking blocks for calibrating the mounting position of the boring die tool on the part to be machined on the boring die tool; portraying central cross lines for calibrating the mounting position of the boring die tool on the part to be machined on the boring die tool; forming a control hole group in the boring die tool; mounting the boring die tool at a position needing the hole group in the part to be machined to form inner circles of control holes of the control hole group, and machining holes in the part to be machined by the aid of control holes of a power boring tool after mounting and adjusting the power boring tool by taking hole end faces as references. The contour dimension of the boring die tool can cover the hole group of the part to be machined, and the distribution condition of the control hole group is as same as that of the hole group of the part to be machined. The boring die tool serves as a reference, a simple device is used for machining the hole group in the large part, and precision requirements of products are met.
