Description

Technical Field [0001] The present invention relates to an automatic nut supply apparatus for tapping machine,

The present invention relates to an automatic feeding device for a nut of a tapping machine, and more particularly, to a method of automatically feeding a nut in a tapping machine for cutting a female thread to an inner diameter of a nut, In particular, when chamfering the outer circumferential surface of the cylindrical body, the nuts falling from the upper portion are first stopped by using the feature that the corresponding portions are not rolled, and then rolled again, so that the pierced portion is positioned in the front- And the inner diameter side of the nut to which the female screw is to be machined is arranged accurately toward the machining means by advancing the screw machining means so that the working time can be further shortened. will be.

Generally, bolts and nuts are used to assemble parts of machinery or industrial equipment. In order to form a screw hole in a metal, first drilling is performed to a diameter slightly smaller than the outer diameter of the bolt to be inserted in the screw hole, And a thread having an appropriate dimension corresponding to the through hole is inserted into the through hole and rotated while supplying lubricating oil or cutting oil at a low speed so as to thread the thread on the inner surface of the through hole according to the size and shape of the screw of the tap. do.

However, tapping that forms a thread depends on manual work or uses a dedicated tapping machine. Manual work is manual tapping because it is difficult to elaborate work, work efficiency is low, and expensive tap is damaged. And there is a disadvantage that it is unreasonable because it is hard to work on a vertical surface or a ceiling.

In addition, in the case of a dedicated tapping machine that automatically rotates the tabs and processes the threads of the nut, it is advantageous that the tapping operation is simple and precise, but the nut that is the object to be processed must be manually supplied manually As well as labor costs.

In addition, there is a problem that if the operator can not supply the nut to the tapping machine precisely in the inner diameter direction in which the thread is to be formed, defective products may be generated.

In order to solve such a problem, Japanese Patent Application No. 10-1291620 (published on Aug. 31, 2013) filed by the present applicant has a base plate, a moving plate horizontally movably installed on the base plate, A first cylinder mechanism installed on the moving plate and horizontally moving the moving plate according to whether the moving plate is operated or not, nut supplying means provided on the center of the moving plate and supplying the nuts sequentially, A fixing jig which is rotatably installed in front and fixes and holds the nut supplied individually through the nut supply means according to the rotation, and a fixing jig which is horizontally movable on both sides of the nut supply means, Is formed in the shape of a connected "C" And a second cylinder mechanism which is provided on the moving plate and is located behind the pressing member and horizontally moves the pressing member according to whether the fixing member is operated or not. A nut automatic feeding device of a tapping machine is disclosed.

However, in the conventional automatic nut feeder of the tapper as described above, it takes a relatively long time to align the nipped portion of the nut with the nut processing means.

The second stopper projection 231 The rear portion of the unit feeding means 200 including the rear side unit feeding member 210 and the front side unit feeding member 230 simultaneously protrudes into the vertical feeding line 120 of the nut feeding body 100, The unit supply means 200 including the rear unit supply member 210 and the front unit supply member 230 and the front of the unit supply means 200 supporting the lower portion of the nut 150 positioned at the front Only the nut 150 located at the lowermost position while being detached from the supply line 120 is caused to fall down to the lower position where the nut guide 300 is mounted. The second stopper projection 231 is provided below the first stopper projection 212 of the rear side unit supply member 210. [

A nut guide 300 is coupled directly under the vertical supply line 120 and horizontally arranged in the second horizontal supply line 130. The nut guide 300 supports the nuts 150 supplied by the unit feeding means 200 from below and the nuts 150 are connected to the second horizontal supply line 130 And serves as a rolling guide for rolling.

As shown in FIGS. 2 and 8, the nut guide 300 is formed of a plate having a shape of '''so that the nut 150 can be pushed forward and rolled down.

On the tapping device in which the nut supplying main body 100 is additionally provided, the forward feeding means 400 is provided so as to be movable in the forward and backward directions with respect to the nut feeding main body 100. The forward feed means 400 pushes the unit feed means 200 forward and moves the feed unit 200 forward and pushes the nut 150 positioned on the nut guide 300 down to the second horizontal feed line 130 The nut 150 is lowered from the unit feeding means 200 and the nut 150 is moved backward by the nut guide 300 To be dropped.

As shown in detail in FIG. 2, the forward transfer means 400 is installed to be movable in the forward and backward directions with respect to the nut supply main body 100 on the tapping machine by a cylinder mechanism (not shown) A transfer plate 410 having a pressing member 411 protruding forward and pressing the unit feeding means 200 to move forward and a transfer plate 410 coupled to both sides of the upper surface of the transfer plate 410, 410 push the nuts 150 positioned on the nut guide 300 to be rolled down to the second horizontal supply line 130 and forward to be screwed by the screw processing means 600 A transfer protrusion 420 for supporting another nut 150 dropped from the unit supply means 200 at the lower portion and dropping the nut 150 to the nut guide 300 at the rear of the transfer plate 410 .

On the other hand, the pressurization and rotation preventing means 500 is elastically pressed toward the inside of the second horizontal supply line 130 on both outer surfaces of the second horizontal supply line 130 of the nut supply main body 100 described above. When the nut 150 is forcibly fed forward by the forward feed means 400 in the second horizontal feed line 130 for threading by the screw processing means 600, The nut 150 is not rotated any more so that the ribs 151 are arranged in the front-rear direction so that the nuts 150 are not rotated any more. ]
