specific Embodiment approach
[0018] The specific embodiment provided by the invention is as follows:
[0019] Specific implementation methods: such as Figure 1-Figure 6 As shown, the processing method of the U-shaped mouth of the inner valve body of the automatic transmission includes step 1, clamping and processing the outer surface of the part according to the blank reference, using a rod milling cutter to feed inward vertically, and the cutting sequence is 1→2→3→ 4. The speed is S16000, the feed is F800, and the down milling method is adopted. The arc part of the U-shaped mouth is processed by the side edge of the rod milling cutter; step 2, the valve core hole is clamped and processed according to the process standard, and the ball end rod milling cutter is selected to be vertically inward. The feed and feed sequence are 1→2→3→4, the speed is S16000, the feed is F160, and down milling is also used, and the arc part of the U-shaped mouth is processed by the ball head.

The invention provides a method for machining a U-shaped opening of an inner side valve body of an automatic transmission, and relates to the technical field of machining of automatic transmission accessories. The method solves the problems that as a conventional method for machining the U-shaped opening of the inner side valve body of the automatic transmission has a great influence on clamping, cost and rhythm of mass-produced workpieces, the application of the conventional method in a production line is unfavorable. The method for machining the U-shaped opening of the inner side valve body of the automatic transmission comprises the following steps of: clamping and machining the outer surface of a workpiece according to blank benchmarks, vertically and inwards advancing a rod milling cutter, carrying out cutter feeding in an anti-clockwise direction, and machining the circular-arc part of the U-shaped opening by means of the side edge of the rod milling cutter; and step two. clamping and machining a valve core hole according to technological benchmarks, vertically and inwards advancing a ball head rod milling cutter at a position different from the position in the step one, carrying out cutter feeding in an anti-clockwise direction, and machining the circular-arc part of the U-shaped opening by means of a ball head. The method effectively ensures the degree of symmetry of the U-shaped opening with respect to the valve core hole, reduces the wearing of the cutter and prolongs the service life of the cutter.
Description
technical field [0001] The invention relates to a processing method for a U-shaped opening, in particular to a processing method for a U-shaped opening of an inner valve body of an automatic transmission, and belongs to the technical field of automatic transmission accessories processing. Background technique [0002] At present, the inner valve body is a very important part in the development and design improvement of new automatic transmission products, and the processing of the spool hole, labyrinth wall, and U-shaped mouth of the inner valve body has always been the top priority, and the U-shaped mouth is difficult to process. Higher: 1. The particularity of technical requirements. It is necessary to ensure the symmetry of the U-shaped port relative to the valve core hole and the width of the U-port at the same time, requiring high precision; 2. The particularity of the structural size. It is a thin-walled suspended part, the processing state is unstable, and it is pron...
