Abstract
The present invention relates to a method for processing a tooth key, a key slot and a hidden convex key of a clamping pin type electric connector. The method comprises the following steps: broaching the center of a metal tube, fine turning the inner wall and inward punching the outer wall of the metal tube to form the hidden convex key; fine turning the outer surface of a head base by taking the hidden convex key as the positioning reference, keeping a processing allowance of the tooth key thickness, cutting the outer surface of the head base by a multi-angle female die in a tooth key shape to form the multi-angle tooth key, then fine turning the outer surface of the other end of the metal tube and turning threads; fine turning the outer surface of a tail base by taking the hidden convex key as the positioning reference, turning threads, fine turning the inner surface of the other end of the tail base, and then cutting the inner surface of the tail base by a multi-angle male die in a key slot shape to form the multi-angle key slot. The processing method has the advantages of uniform reference, simple procedure, high work efficiency and low processing cost. Important high-precision components of the electric connector can be produced by simple mechanical processing.
Description
Technical field
The present invention relates to the processing method of alligator in the electric connector, keyway and dark protruding key, particularly bail type electric connector multi-angle flower alligator and the keyway of precision-fit and the processing method of the protruding key of internal shape cavity with it.
Background technology
No matter be forceful electric power or light current, as long as make electricity consumption that the existence of electric connector just be arranged.Because we self the safety that directly relates to safe in utilization of electricity is so people are more and more higher to the safety guard performance requirement of electric connector.Prior art has been invented the butt joint angle of multi-angle spline, keyway control connection part, the butt joint direction of dark protruding key control self, and electric connector is blind inserts the function that misplugs between the similar connector thereby give.What close the key control butt joint in the electric connector mainly contains headstock, tailstock and Connection Block.Mainly in the internal shape cavity of headstock and tailstock one end, the multi-angle spline is at the other end periphery of headstock for dark protruding key, and keyway is in the internal shape cavity of the tailstock other end.The traditional diamond-making technique of the alligator of electric connector, keyway and dark protruding key is to mill processing, gear shapping machine processing by precision milling machine.These traditional diamond-making techniques use import equipment, and the one, the import equipment costliness, the procedure complexity, working (machining) efficiency is lower; The 2nd, multiple tooth bond angle degree control is inaccurate, and it is inaccurate to cause the bull toe joint to be inserted.
Summary of the invention
The invention provides that a kind of cost is low, operation is simple, product precision height, high efficiency just can realize the processing method of alligator in the electric connector, keyway and dark protruding key by common process equipment.
The present invention is achieved in that
(1) metal tube is fixed on center reaming on the lathe, the finish turning inwall is to φ A dimensional requirement;
(2) metal tube is enclosed within on the die plug of dark protruding key shape, makes the metal tube outer wall inwardly form dark protruding key, i.e. dark protruding key on headstock or the tailstock inwall by mechanical stamping;
(3) taking off the die plug, serves as the location benchmark with dark protruding key, and the dark protruding key end external surface of finish turning metal tube is to φ B dimensional requirement;
When a, processing headstock, finish turning headstock external surface leaves the back road allowance of alligator thickness (RB-RA) * (0.2-0.5), and forms escape;
Headstock is fixed in the punch press frock together with collet expander, and the die cutting headstock external surface with multi-angle alligator shape forms the multi-angle alligator;
The dark protruding key end of metal tube is put in collet expander be fixed on the lathe finish turning metal tube other end, external threading again.
When b, processing tailstock, finish turning tailstock external surface puts in collet expander with the dark protruding key end of metal tube and is fixed on the lathe, and the finish turning metal tube other end to φ C dimensional requirement, forms escape with interior shape face finish turning;
Tailstock is fixed in the punch press frock together with collet expander,, forms the multi-angle keyway, again external threading with shape face in the punch cutting tailstock of multi-angle keyway shape;
(4), be formed with the headstock of dark protruding key and multi-angle alligator or the tailstock of dark protruding key and multi-angle keyway is arranged with semi-finished product workpiece finish turning.
φ A has the inner diameter of dark protruding key one end in the above for head, tailstock, φ B has the outer diameter of dark protruding key one end for head, tailstock, φ C is the inner diameter that tailstock has keyway one end, and the size of concrete φ A, φ B, φ C is determined according to the concrete dimensional requirement of electric connector different series.
Description of drawings
Fig. 1 is an electric connector headstock front view of the present invention;
Fig. 2 is an electric connector headstock vertical view of the present invention;
Fig. 3 is an electric connector tailstock front view of the present invention;
Fig. 4 is an electric connector tailstock vertical view of the present invention.
Among the figure, alligator 1, dark protruding key 2,4, keyway 3.
The specific embodiment
Below in conjunction with accompanying drawing processing method of the present invention is described further.
With the bail type electric connector headstock in processing shown in the accompanying drawing and alligator, keyway and the dark protruding key of tailstock is example, and wherein φ A is that 23mm, φ B are that 28mm, φ C are 20mm, and its procedure of processing is:
1, be that φ 40mm, internal diameter are that the metal tube of φ 20mm is fixed on and carries out the center reaming on the lathe with external diameter, internal diameter expands the 22mm to φ, and the finish turning inwall is to φ 23 ± 0.03mm;
2, take off through rough machined metal tube, it is enclosed within on the die plug of dark protruding key shape, and be fixed in the punch press frock, start punch press, inwardly form dark protruding key by drift extrusion metal pipe outer wall, be the dark protruding key on headstock or the tailstock inwall, dark protruding key 2 as shown in Figure 1, dark protruding key 4 shown in Figure 3;
3, taking off the die plug, serves as the location benchmark with dark protruding key, and the dark protruding key end external surface of finish turning metal tube is to φ 28mm on precision meter lathe.
When a, processing headstock, finish turning headstock external surface, leave the back road allowance of alligator thickness (28/2-23/2) * 0.3=0.75, and formation escape, headstock is fixed in the punch press frock together with collet expander, die cutting headstock external surface with multi-angle alligator shape forms the multi-angle alligator; The dark protruding key end of metal tube is put in collet expander be fixed on the lathe finish turning metal tube other end, finish turning external screw thread again;
When b, processing tailstock, finish turning tailstock external surface, the dark protruding key end of metal tube is put in collet expander to be fixed on the lathe, the shape face is to φ 20mm in the finish turning metal tube other end, and formation escape, with shape face in the punch cutting tailstock of multi-angle keyway shape, form the multi-angle keyway, again the finish turning external screw thread;
Above working angles is by the repeatedly extruding of mould material to be cut, and forms the alligator or the keyway of multi-angle;
4, the semi-finished product workpiece is fixed on finish turning on the precision meter lathe together with collet expander, finally is formed with the headstock of dark protruding key and multi-angle alligator or the tailstock of dark protruding key and multi-angle keyway is arranged.
This processing method unifying datum, operation is simple, high efficiency, processing cost is low, by simple machining, produces high-precision electric connector vitals.
