Tapered screw threads can be turned out on the tapered inclined plane by a tooth turning mechanism, then the pipe joints which are formed can be cut out from the tubing through a cutting device, and the actions can be automatically and repeatedly carried out.
Description
The utility model is a kind of coupling two ends gradient tooth automatic machining devices, belongs to the pipe joint automatic machining device.
Pipe joint commonly used at present, be as shown in Figure 1 and Figure 2 in order to as pipe arrangement with two ends and short shape pipe joint with inside and outside tapered thread 101,102, known in order to make the method for the pipe joint 10 that this kind two ends have tapered thread, more representative have following two kinds:
First kind is the lathe turning method: this kind method is strip steel pipe material (hereinafter to be referred as the pipe material) to be cut out earlier be sawn into a section about about 100 centimetres middle length pipe material, again with the pipe feed collet of length in this on the chuck of lathe, in the mode of manually-operated lathe tool length pipe material in this is whittled into a bit of pipe joint 10 as shown in Figure 1 and Figure 2.
Second kind is to attack modulus method: this kind method is to be sawn into strip steel pipe material sanction a bit of earlier, and after making the short tube material that its length equates with pipe joint, fix this short tube material again and in its two ends attacking mould tapping tapered thread, so make Fig. 1, pipe joint 10 shown in Figure 2.
Though the method for above-mentioned two kinds of known manufacturing pipe joints can be manufactured pipe joint, yet two kinds of methods all have many shortcomings, now are respectively described below:
The shortcoming of one, lathe turning method:
1. for stressing speed of production, this kind lathe turning method during cutted thread, all is not adopt parts to operate automatically by the operator with visual operation on the taper inclined-plane of turning tapered thread with on this inclined-plane.Thereby the gradient on its taper inclined-plane and the pitch of thread all are range estimations and be to be difficult to reach standard, so precision is relatively poor.
2. for stressing speed of production, this kind lathe turning method utilize chuck clamp in behind the pipe material of length, and the tail end of length pipe material in withstanding without the tailstock of lathe, because could in this, be lathed one section pipe joint by the tail end of length pipe material like this, length pipe material increases speed of production unceasingly at second pipe joint of its tail end car system in immediately this pipe joint being cut off.Yet owing to so pursue speed of production, and length pipe material does not utilize tail stock to withstand under the situation at center at tail end in making, the disadvantage of the eccentric rotation of tail end takes place.Even and if the disadvantage of the eccentric rotation of this kind is seldom eccentric, also the tapered thread that turning is formed loses the specification of standard, and its precision is reduced.
3. and utilize lathe dog clamp in length pipe material, also only terminate in the tapered slope and the screw thread of car system single face, (face) the car system again of still must changing sides, not only labor intensive and man-hour (must correction center) thus, and difficulty aligns the centrad on its two sides (limit), causes precision relatively poor.
4. because though this kind lathe turning method is used lathe, yet all do not use the parts of lathe and do " rule " for stressing speed of production, thereby the pipe joint quality of its production can't unify, and because be estimating car system, so underproof to scrap pipe joint extremely many.
5. because this kind lathe turning method relies on manually fully, so do not have " automation " to say, and a people only can operate one one, production efficiency is very low.
Two, attack the shortcoming of modulus method:
1. because the tapered thread of pipe joint and non-once are attacked mould just can form, must divide as usual tapping and attack mould for one, two, No. three and attack deep thread one by one and finish, so it is long to produce time of pipe joint, speed of production is slow, influences cost.
The mould consumption of 2. attacking mould is bigger, and a large amount of production pipe joints is not calculated, and cost is too high.
3. this kind attacked the effect that modulus method still can't reach automatic manufacturing pipe joint.
The method of above-mentioned two kinds of manufacturing pipe joints commonly using no doubt has shortcoming to be worth improving.Yet reach the primary difficulty that pipe joint is produced automatically, the car system that also is the tapered thread of pipe joint must gradation turning be deepened depth of cut one by one and just can be finished, when promptly reaching machinery from the motor-car pipe joint tapered thread at the car pipe joint, must have the gradation feed and deepen the ability of depth of cut one by one, otherwise just can't reach purpose from the casing joint of motor-car system.
The purpose of this utility model is: provide a kind of and can continuously strip steel pipe truck be made countless pipe joint joints automatically and constantly, and the automatic machining device that its two ends gradient tooth is processed automatically, product precision is good, production efficiency is high, and can save manpower and man-hour, cost is low, can realize the continuous automatic production of pipe joint.
A kind of coupling of the utility model two ends gradient tooth automatic machining device, it comprises:
One transmission device is by hollow main shaft, exempt to stop institutes such as chuck, idle pulley and power transmission shaft and constitute;
One pay-off utilizes weight pulling stay cord to make the pipe material be drawn forward moving the propelling movement;
