Abstract

The invention relates to a processing tool, in particular to a processing tool and a processing method for a novel net rack bolt ball. A numerically-controlled dividing apparatus comprises a Y-shaft dividing base; the left end of the Y-shaft dividing base is provided with a left dividing disc base positioned together with the Y-shaft dividing base; the right end of the Y-shaft dividing base is provided with a right dividing disc base positioned together with the Y-shaft dividing base; the Y-shaft dividing base is internally provided with an X-shaft index chuck; the X-shaft index chuck is internally provided with uniformly distributed clamping strips which are slidably connected with the X-shaft index chuck; a clamping interface is internally provided with a bolt ball centering pin which is in clamped with the clamping interface; the upper part of the bolt ball centering pin is provided with a bolt ball; and the bolt ball and an operation drill are correspondingly distributed. The processing method is implemented through the following steps: processing a bolt ball relief hole; positioning a bolt ball; processing a split surface; and drilling holes. The processing tool for the novel net rack bolt ball is compact in structure; and the processing tool and the processing method can be used for effectively improving the processing precision, improving the processing efficiency and lowering the cost.

Description

[0001] technical field [0002] The invention relates to a processing machine tool, in particular to a processing machine tool and a processing method of a novel network frame bolt ball. Background technique [0003] The application of modern grid structure is becoming more and more common, and it has been successfully applied to various large exhibition halls and terminal buildings. It is also getting higher and higher, especially the processing of bolt balls. [0004] The traditional bolt ball processing method is to modify the ordinary lathe, remove the tool holder, install manual indexing tooling, fix the milling, drilling, tapping and other tools on the spindle, and drive the tool through the rotation of the spindle to achieve the bolt ball. , Drilling and tapping purposes. This method is more suitable for the processing of small buildings such as ordinary workshops, but for large-scale bolted ball grid structures with complex shapes and many rods, it is difficult ...

[0005] The manual indexing tool is indexed and positioned through the indexing line on the tooling, and the angle deviation of the bolt ball is small, which can meet the installation accuracy requirements for the general plant bolt ball grid, but for large and complex structure grids, Because the connecting rods are large, the angles are different, and the cumulative error is large, if it is processed according to conventional precision, the installation quality will be affected; the bolt ball processing machine tool modified by ordinary lathe adopts the method of horizontal feed processing , for the workpiece processing, the relative position to the tool is not easy to observe and control, and the positioning deviation cannot be found and adjusted in time, which will lead to the scrapping of the workpiece and waste of materials; the indexing is controlled manually, and the quality fluctuates greatly due to the influence of human factors

Each hole needs to be positioned repeatedly three times, and each positioning is prone to deviation, resulting in misalignment of the hole surface and affecting the appearance quality of the part

[0006] At present, large-scale CNC machining centers are also continuously applied to the processing of some complex parts, such as gear processing, bearing processing, etc., which have high precision, but are not suitable for the processing of bolt balls. It is mainly reflected in the following aspects: General Large-scale CNC machining centers are all five-dimensional CNC (that is, 3+2), and their programming process is quite cumbersome. This requires a high level of cultural quality and learning and training for operators, and ordinary technicians cannot operate in a short period of time; and the complex structure The bolt balls have different hole angles for each ball, which requires a lot of time and manpower to complete the programming work, which not only does not improve efficiency, but is labor-intensive and time-consuming; when CNC machining centers are processed, the whole process is automatically operated , the feed stroke of each tool is pre-set, which has high requirements for the accuracy of the part blank, and the bolt ball is formed by heating forging, and the surface accuracy of the blank is low, which is easy to cause the tool stroke too short or too long

If the stroke is too short, the machining depth of the hole will be insufficient, and if the stroke is too long, the tool will be damaged; when the bolt ball is processed, only three-dimensional processing (ie 1+2) is required, such as five-dimensional processing of the CNC machining center, It is obviously overkill and waste of resources, and the price of CNC machining center is high, and the cost of maintenance and maintenance is also high, which increases the production cost of the enterprise and is not conducive to the market competition of the enterprise
