Embodiment Construction

[0018] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail.

[0019] The invention provides a processing method of a thread with a fixed starting point, which specifically includes the following steps:

[0020] S1. Process the outer diameter of the part to the thread state to be processed according to the technical requirements;

[0021] S2. Axial tool setting: In order to find the position 4 of the starting point of the axial thread, make the angle of the knife edge on the outside of the thread starting template coincide with the angle of the CNC thread turning tool; figure 2 As shown, the thread start template is L-shaped, the thread start template is aligned with the part, and the datum coincides; the outside of the thread start template is provided with a pair of knife edges, and the distance between the pair of knife edges and the reference...

Abstract

The invention discloses a machining method of a fixed starting point thread. The machining method comprises the following steps: machining an outer-diameter size of a part to a thread to be machined state; then carrying out axial tool setting and circumferential tool setting respectively; finally, machining the fixed starting point thread according to a determined tool starting point. By adopting the machining method of the fixed starting point thread, the precision of a fixed starting point position can be effectively improved, and a difficulty barrier of machining the fixed starting point thread is broken; the reliable machining quality is guaranteed, and size consistency and interchangeability are good; the machining method of the fixed starting point thread has the effect of improving the machining efficiency and the yield.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a processing method for fixed-point threads. Background technique [0002] The fixed-point thread requires a specified mutual position relative to the thread axis in the axial and circumferential directions, and specifies the coordinate position of any point on the pitch diameter of the thread of the two parts that cooperate with each other relative to the assembly datum to ensure that the assembled parts have a specified relative position. The processing method of ordinary thread cannot meet the requirements. Contents of the invention [0003] The object of the present invention is to provide a processing method of fixed-point thread, which solves the problem of determining the axial position and the circumferential position of the fixed-point thread processing starting point. [0004] The technical solution of the present invention is: a method for processing fix...
