Problems solved by technology

The traditional processing method is to use a CNC machining center for processing, which takes a long time to process, has high costs, and requires special special fixtures; the second is to use a CA6140 lathe for processing, because it cannot be processed by a CA6140 lathe Direct clamping and positioning, so the processing of this type of parts cannot be realized

Embodiment 1

[0028] like figure 1 Shown regular triangular pyramid, its processing method comprises the following concrete steps:

[0029] (1) Make the auxiliary fixture: design the clamping hole 1 and the inclination angle of the auxiliary fixture according to the key properties of the regular triangular pyramid, and the inclination angle is 160.53°, such as image 3 shown;

[0030] (2) Processing step 1: blanking, processing the blank into a bar, and processing the process chuck 4 with an ordinary lathe, such as figure 2 shown;

[0031] (3) Processing step 2: Put the workpiece with the process chuck 4 on the auxiliary fixture, make the workpiece’s process chuck 4 fall into the clamping hole 1 and use the pressure plate 3 to position the workpiece firmly, and then clamp the auxiliary fixture and the workpiece The first plane of the workpiece is machined on an ordinary lathe, and the right end face of the auxiliary fixture is used as the basis for cutting positioning during processing,...

Embodiment 2

[0038] like Figure 7 Shown right-angled triangular pyramid, its processing method comprises the following concrete steps:

[0039] (1) Make the auxiliary fixture: Design the clamping hole 1 and the inclination angle of the auxiliary fixture according to the key properties of the right-angled triangular pyramid, and the inclination angle is 144.74°, such as Figure 9 shown;

[0040] (2) Processing step 1: blanking, processing the blank into a bar, and processing the process chuck 4 with an ordinary lathe, such as Figure 8 shown;

[0041] (3) Processing step 2: Put the workpiece with the process chuck 4 on the auxiliary fixture, make the workpiece’s process chuck 4 fall into the clamping hole 1 and use the pressure plate 3 to position the workpiece firmly, and then clamp the auxiliary fixture and the workpiece The first plane of the workpiece is machined on an ordinary lathe, and the right end face of the auxiliary fixture is used as the basis for cutting positioning during...

Abstract

The invention provides a machining method for turning a regular triangular pyramid or a right-angled triangular pyramid. The method comprises the steps as follows: preparation of an auxiliary clamp: a clamping hole and an inclination angle of the auxiliary clamp are designed according to determinant attributes of the regular triangular pyramid or the right-angled triangular pyramid; blanking: a blank material is machined to a bar stock, a technological chuck is machined by a common lathe; the auxiliary clamp is mounted on a workpiece provided with the technological chuck, and a first plane of the workpiece is machined on the common lathe; the machined workpiece rotates for 60 degrees around a central axis of the clamping hole, and after the workpiece is positioned firmly, the auxiliary clamp and the workpiece are clamped on the common lathe so as to machine a second plane of the workpiece continuously; the steps are repeated to machine a third plane of the workpiece; and finally, an ejector pin is utilized to center a central line of a rudiment of the regular triangular pyramid or the right-angled triangular pyramid, then the technological chuck is cut off, and the machining of the regular triangular pyramid or the right-angled triangular pyramid is completed. The machining method is matched with the self-made auxiliary clamp and is simple and fast, the accuracy of a formed part is guaranteed, simultaneously the work efficiency is improved, and the machining cost is saved.

Description

technical field [0001] The invention relates to a processing method of a regular triangular pyramid or a right-angled triangular pyramid, belonging to the field of mechanical processing technology. Background technique [0002] Regular triangular pyramids and right-angled triangular pyramids are non-revolving parts. The processing of such parts requires the design of process auxiliary fixtures and the arrangement of reasonable processes and procedures according to the special properties and characteristics of the parts themselves. The traditional processing method is to use a CNC machining center for processing, which takes a long time to process, has high costs, and requires special special fixtures; the second is to use a CA6140 lathe for processing, because it cannot be processed by a CA6140 lathe Direct clamping and positioning, so the processing of this type of parts cannot be realized. Contents of the invention [0003] The object of the present invention is to prov...
