Embodiment 1

[0058]In this embodiment, a 3-axis machining center with X, Y, and Z axes perpendicular to each other is used to process cylindrical workpieces in the manner of "workpiece is stationary, the tool head rotates a certain angle along a certain axis, and then feeds a certain distance along a certain axis" The clamp used in the process of the structure of the groove, groove, etc. is taken as an example to illustrate the present invention.

[0059]Such asfigure 2 The CNC milling tooling fixture for the middle shell shown in -8 includes: a first fixture 1, a second fixture 2 and a third fixture 3;

[0060]The first clamp 1 includes a left positioning plate a22 and a right positioning plate b23. The left positioning plate a22 has protrusions on one side and a flat surface on the other side; the right positioning plate b23 has two round protrusions on one side and a flat surface on the other side. ; The two ends of the workpiece to be processed are respectively clamped by the left positioning plat...

Embodiment 2

[0076]This embodiment uses a hollow shaft sleeve type cylindrical workpiece shown in Figure 1 to illustrate the present invention:

[0077]The method for machining a workpiece using the CNC milling tooling fixture for the middle shell described in Example 1, includes the following steps:

[0078]As shown in Figure 1-8:

[0079](1) Connect the protrusion on one side of the left positioning plate a22 of the first fixture 1 to one end of the workpiece to be processed, and the two circular protrusions on the side of the right positioning plate b23 of the first fixture correspond to the other end of the workpiece to be processed Connection; Place the workpieces that have been loaded into the fixture on both sides on the workbench, and clamp the workbench;

[0080](2) Use the angle formed by the sides 7D1 and 8E1 of the first fixture 1 and the lengths of the sides D1 and E1 as positioning, and obtain a right-angle groove by CNC machining; use the length and angle of each side of the positioning plate...

Abstract

The invention relates to an intermediate shell CNC milling tool clamp and a use method. The intermediate shell CNC milling tool clamp comprises a first clamp body, a second clamp body and a third clamp body. Each clamp body is provided with two positioning plates, the two ends of a workpiece to be clamped are restrained through the positioning plates, the workpiece is clamped, and three machiningprocedures are completed. By means of the three machining procedures, one clamp body is adopted in each procedure, and the specific portions of the workpiece are machined. The edges with correspondingangles and lengths on the clamp positioning plates are used for positioning, the machining efficiency of the workpiece can be improved on the basis of ensuring the machining precision, and the clampis simple in structure, easy to machine and suitable for clamping the cylindrical workpiece, and compared with traditional index plate clamping, the influence on the cylindrical face is smaller.

Description

Technical field[0001]The invention relates to the field of mechanical processing, in particular to a CNC milling machining tool fixture for a middle shell and a use method.Background technique[0002]In the prior art, an indexing plate is used to clamp a workpiece of a middle shell for processing. As the production capacity increases, it is necessary to replace the indexing plate clamping with a CNC tooling fixture.[0003]CNC is a 3-axis machining center. The angle of the machining axis is fixed and non-adjustable. The middle shell workpiece is a cylindrical workpiece. Manually adjusting the angle of the workpiece during the machining process will cause serious deviations and greatly affect the yield of parts. Realize high efficiency processing.Summary of the invention[0004]In view of the above-mentioned problems in the prior art, the present invention provides a CNC milling tooling fixture for a middle shell and a method for processing a workpiece using the fixture. Three sets of posi...
