Embodiment Construction

[0027] The present invention will be further described below in conjunction with the drawings and embodiments.

[0028] Such as Figure 1-5 The structure diagram of the cast beam is given. The processing process is:

[0029] 1) The above plane 2 and the left side 3 are coarsely positioned, clamped by a movable platen tool, processed on the X2010A gantry milling machine, and milled with a φ350 three-sided disc milling cutter tool to mill the bottom surface 1 (see figure 1 );

[0030] 2) Position the bottom surface 1 below, clamp it with a movable platen tool, and process it on the X2010A gantry milling machine. Use a φ32 three-sided disc milling cutter to mill the upper plane 2 (see figure 1 );

[0031] 3) The following bottom surface 1 and inner elliptical end surface 13 are used for positioning, and clamped by a moving pressure plate type screw clamping tool. 2 -1258C end face milling machine processing, with φ100 set of face milling cutter tools, milling the left side 3 and rig...

Abstract

The invention relates to a processing technique for casting a beam of an automobile chassis, which comprises the following steps of: (1) milling a lower bottom surface, (2) milling an upper plane surface, (3) milling two lateral sides, (4) drilling a hole in the lower surface, (5) drilling a hole in the upper surface, (6) drilling holes at the two lateral sides, (7) boring holes at two lateral inclined surfaces, (8) milling an inner convex plate inclined surface at one side, (9) milling the inner convex plate inclined surface at the other side, (10) drilling screw holes on the inner convex plate inclined surface, (11) tapping inclined surface screw holes, (12) back facing of a hole table-board on the lower bottom surface, (13) back facing of a hole table-board on the upper plane surface and (14) back facing of hole table-boards on two lateral surfaces. The technique process has reasonable procedure arrangement, is convenient for the positioning and clamping of work pieces, and can guarantee the precision requirement of the work pieces and high processing efficiency.

Description

Technical field [0001] The invention relates to a processing technique of a beam, in particular to a processing technique of a cast beam of an automobile chassis. Background technique [0002] Casting beam is a main product of automobile chassis. In order to achieve the required precision during the processing of the cast beam, it is necessary to formulate a set of special processing technology. There is no such technology at present. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a high-efficiency machining process for automobile chassis casting beams that can ensure the design accuracy requirements. [0004] In order to achieve the above objectives, the present invention adopts the following technical solutions: [0005] A processing technology for casting beams of automobile chassis includes the following steps: [0006] 1) Mill the bottom surface, the upper plane and the left...
