Abstract

The invention relates to a grinding device and a grinding method for a spiral groove of a receiver of a spin tube gun. A grinding rod performs a resultant motion of a circulation motion and a reciprocating linear motion along the spiral groove of the receiver. Under the action of grinding paste, the grinding rod can grind unequal traces left by processing tools on two sides of the spiral groove equally. By applying the device to the spiral groove of the receiver, the spiral groove is ground till no tool traces are available on two sides, and the grinding rod can slide smoothly in the spiral groove. Flaws caused by processing errors are eliminated in this way, so that a roller of a gunlock of an aircraft gun system can move smoothly in the spiral groove, and therefore, an automatic machineof the aircraft gun system works smoothly.

Description

technical field

[0001] The invention belongs to the field of spiral grooves of a gun case of a rotary cannon, and in particular relates to a grinding device and a grinding method for a spiral groove of a gun case of a rotary cannon. Background technique

[0002] At present, there are two processing methods for the spiral groove of the gun case of the domestic rotary gun. One is to process the spiral insert and fix it on the gun case by welding and screw fastening; the other is to divide the gun case where the spiral groove is located into two parts. The parts are processed, and half of the spiral groove is distributed symmetrically for each part. After the processing is completed, the two parts are connected together with screws to realize the butt joint of the spiral groove. Both of these two spiral groove processing methods have the problem of docking accuracy with the gun case, mainly in the following two points:

[0003] First: In the process of welding and fixing the i...
