Embodiment Construction

[0015] The present invention will be described in detail below in combination with specific examples.

[0016] A method for deburring the front half of a thread, comprising the following steps in sequence:

[0017] Step 1. Visually align the threaded cutting edge of the part with a certain scale of the fixture and clamp it on the chuck, and manually move the milling cutter down to the determined position of the milling cutter positioning block;

[0018] Step 2. Turn the handle of the special fixture counterclockwise to drive the processed part to rotate. The thread of the processed shell rotates along the circumference on the one hand, and moves upward along the axial direction on the other hand. The axis of the cutting milling cutter and the axis of the part form a fixed clamp horn;

[0019] Step 3. When the positioning screw of the fixture blocks the positioning block, milling;

[0020] Step 4. Turn the handle clockwise by hand until the other screw blocks the positioning ...

Abstract

The invention relates to a method for removing thread front half-buckled burrs. The method comprises the following steps in sequence S1, a thread inlet edge of a part is visually aligned to a certainscale of a clamp and is clamped on a chuck, a milling cutter is manually moved to a position where a milling cutter positioning block is determined; S2, a special clamp handle is manually pulled anticlockwise to enable the special clamp handle to drive a machined part to rotate, the thread of the machined shell rotates along the circumference and moves upwards along the axial direction, and an included angle is formed between the axis of the cutting milling cutter and the axis of the part; S3, when a clamp positions a screw blocking and positioning block, milling is carried out; and S4, the handle is manually pulled clockwise to the other screw blocking and positioning block, the milling cutter is lifted, and the part is removed. The method is simple in clamp, convenient to operate and good in burr removing effect.

Description

technical field [0001] The invention relates to a method for removing burrs from the first half of a screw thread, and belongs to the technical field of industrial processing. Background technique [0002] The housings of electrical connector products are mostly threaded, and most of the thread processing is done on a lathe. After turning, the thread profile of the first half of the thread is reversed to one side and has an irregular sawtooth burr shape, which not only affects the appearance quality of the product, but also affects the connection performance of the thread. Moreover, there is a large gap with foreign samples, especially the front and rear of the thread. Parts with sipe, larger pitch, and better material plasticity (such as stainless steel) are more serious. Originally, the shells were mostly made of aluminum. In recent years, due to the increasing market demand for stainless steel shells, the workload of deburring has increased dramatically. In the past, th...
