Embodiment Construction
[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0024] Such as Figure 1-Figure 5 Shown, a kind of technology of processing civil air defense door shaft, comprises the following steps:
[0025] Step 1: Place the raw material on the lathe, and turn the raw material into a cylindrical workpiece 01;
[0026] Step 2: placing the cylindrical workpiece 01 on a milling machine, performing two milling processes on the end face of the cylindrical workpiece 01 symmetrically with the center of the circle as the center, and processing the first semi-finished product 02;
[0027] Step 3: Install the eccentric block 2 on the chuck claw 1 on the lathe, so that the rotation center of the workpiece is located at the first eccentric center 001; the unprocessed end of the first semi-finished product 02 is the clamping end, and the clamping end is clamped on Carry...

Abstract
The invention relates to a civil air defence door spindle machining technology. The civil air defence door spindle machining technology comprises the following steps that 1, a raw material is machinedinto a cylindrical workpiece through turning; 2, the end face of the cylindrical workpiece is symmetrically subjected to two times of milling with the circle center as a center, and a first semi-finished product is machined out; 3, an eccentric block is installed on a chuck jaw located on a lathe, the end face of one half of the first semi-finished product is machined into an eccentric arc with the eccentric circle center as a circle center, and thus, the first semi-finished product is machined into a second semi-finished product; and 4, the position of the second semi-finished product is adjusted, so that the second eccentric circle center, the first eccentric circle center and the initial circle center of the cylindrical workpiece are located on the same straight line, turning is conducted, the other half of the second semi-finished product is machined into an eccentric arc with the second eccentric circle center as the circle center, and thus, the second semi-finished product is machined into a finished door spindle. According to the civil air defence door spindle machining technology, the workpiece which can be machined out only through a slotting machine is machined out through the lathe and a milling machine, the production procedure is simplified, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a process for processing civil air defense door shafts. Background technique [0002] Civil air defense doors are widely used in civil air defense projects. The end face of the civil air defense door shaft is a special shape spliced by two semicircles and rectangles. The general processing method is to first process the workpiece on a lathe and milling machine according to the drawing, and then process the rough shape, and then use The profiling jig draws the processing line on the workpiece, then inserts the workpiece on the slotting machine, and inserts the excess part along the drawn line. Such a technological process has many steps, the size of the civil air defense door shaft is very large, the shape of the civil air defense door shaft end face is special, and it is difficult to process, so the actual output in production is small.
