Definitions
- the present invention relates to a fly type fly scatter and a mounting method. Since the taper hole is used, the upper end surface of the mounting hole and both side surfaces are fixed, the area of close contact increases, and the mounting strength and cutting accuracy are extremely high.Furthermore, it is an integrated fly scatter even at high speed and heavy cutting The performance of this model is almost the same as that of the above, and it is also related to the shul-type flyer and mounting method that can be easily mounted and removed.
- shell type fly scatter has a smaller contact area between the blade part of the fly scatter and the mounting shaft of the fly server compared to a body type one in which the blade part and the shank part are in close contact Due to the low degree of hardness, all performances such as rigidity, machinability, strength, processing accuracy, and wear resistance were inferior. However, if the size of the fly skutter is large, it is expensive to manufacture an integrated fly skutter, and when the blade is worn, the entire shank is replaced, making it extremely uneconomical. Therefore, an inexpensive and easy-to-manufacture shul type fly scatter, which allows only the blade to be replaced easily, is currently in use. Conventionally, As shown in Fig.
- the conventional method of attaching a shill type fly scatter is to attach the outer circumference (32a) of the sill type fly arper (32) and the sill type fly scatter. This is a method in which a left-hand screw is screwed into one mounting hole (12a), and the two are screwed together to be mounted. This is because the screw is automatically tightened when the cutting process is performed, and the screw type mill cutter (12) Increases the adhesion of the fly super bar (32), enabling high speed rotation and heavy cutting.
- the cutting resistance at this time acts as a load on the thread, and if the cutting resistance increases, the thread will be completely tightened, or if it is severe, seizure will occur, resulting in a seal type fly scatter (12).
- the fly-arper (32) could not be separated, which made it impossible to replace the sieving type fly scatter (12). There are serious drawbacks such as inaccuracy.
- the present invention has been made in order to eliminate the drawbacks of the conventional shell type fly skirt and its mounting method, and is directed to a fly sever having a tip formed in a straight step portion.
- a fly scatter having a hole with a hole slightly larger than the mounting shaft is loosely fitted to the mounting shaft, and these mounting shafts are divided into two pieces in the gap between the taper hole. Insert and engage with the m-groove of the bolt, and then press the taper member into the gap between the mounting shaft and the mounting hole, and identify the slider on the mounting shaft.
- the area where the seal type fly scat is in close contact with the fl ers bar increases, and the protrusion of the taper member and the bolt groove are fitted and engaged.
- the accuracy of the shaft core is extremely high, the flexibility and mounting strength are increased, and high speed and heavy cutting becomes possible. Furthermore, this makes the cutting efficiency almost equal to the performance of the integrated type fly scatter, and the fly scatter can be replaced very easily. It is intended to provide scatter and mounting methods.
- a mounting hole for a scroll type slider is formed in a taper hole, a concave groove of the tightening bolt and a protrusion of the bush are engaged, and the bush is press-fitted. And secure the seal-type flyers to the flyers.
- the contact surface between the shell-type slider and the fly server is Since the product is increased and the adhesion is increased, heavy cutting can be performed at high speed, which is close to the performance of an integrated type flier cutter, and the flier scatter can be replaced very easily.
- FIG. 1 and No. 2 are exploded cross-sectional views showing the conventional method of installing the sill type fly scatter
- Nos. 3 ll (A) and (B) are the sill type fryer scatter and the attaching method according to the present invention.
- FIG. 4 is a cross-sectional view showing the fly scatter for realizing the above and the bottom surface lEl
- FIGS. 4 (A) and ( ⁇ ) are for realizing the seal type force force and the mounting method according to the present invention.
- Fig. 5 ( ⁇ ), ( ⁇ ) shows the shell type fly scatter and mounting method for realizing the mounting method according to the present invention.
- Fig. 6 is the same as the front face and bottom face shown in Fig. 6.
- FIG. 6 is an exploded cross-sectional view showing the mounting method of the seal type fly scatter of the present invention.
- Fig. 7 is the mounting of the type fly scatter according to this study. It is sectional drawing explaining a state, and the 8th frame is a sectional frame which shows the press fitting means by this invention.
- the first is an embodiment of a fly scatterer used in the present invention, in which the shell type fly scatter 1 and the shell type fly scatter 1 have tapered downward mounting holes 1 a at the center thereof. , And a key groove 1c for stopping power is provided at the upper end.
- the fourth flier is a shell type fly according to the present invention.
- 1A and 1B are a plan view and a front view showing a bushing for realizing a scatterer.
- a taber member 2 made of metal and vertically dividing a chever bushing into two pieces, and an inner surface of the taper member 2 are On the trace surface 2a, there is a linear protrusion 2c in the circumferential direction on the lower side, and on the outer surface, there is a taper surface 2b that is in close contact with the taper-shaped mounting hole 1a of the seal type flyscatter 1.
- the length of the taper section forest 2 should be slightly flush with or slightly recessed from both end surfaces of the shell type fly scatter 1 when press-fitted into the mounting hole la of the shell type fly scatter 1. .
- the 5th II is a fly-saver having a mounting shaft 3a whose tip is formed on a straight step portion and a non-rotating key 3c protruding from the step portion, and the length of the mounting shaft 3a is a shell type.
- the size is about ⁇ of the mounting hole 1a of the fly scatter 1, and the screw hole 3b is screwed at the tip.
- No. 6 is an exploded cross-sectional view showing the mounting method of the shell type fly scatter of the present invention.
- the press-fitting means (bolt) 4 has a hexagonal hole 4c with a groove 4b on the outer circumference of the head 4a. It is a bolt, and the projection 2 c of the taper member 2 is fitted into the groove 4 b and engaged with each other.
- the taper member 2 may be press-fitted by directly screwing the taper member 2 and the take-up wheel / wheel 3a in addition to the bolt 4.
- the mounting hole 1a of the scroll type fly scatter 1 is loosely fitted to the mounting shaft 3a of the fly sperper 3 to prevent the two from fastening. Also fit the key groove 1c and the key 3c for the.
- the taper member 2 engaged with is squeezed and press-fitted in by the bolt 4, and the Schul-type fly scatter 1 is attached to the fly-saver 3.
- the mounting hole 1a is a taper hole
- the upper end surface of the mill type milling scatter 1 comes into close contact with the step end surface of the milling spar 3 and the mounting hole 1a is tapered.
- the member 2 is compressed, and the two divided taper members 2 come into close contact with the mounting shaft 3a.
- the shell type friction force 1 is mounted by mounting the upper end face and the taper 1 through the member 2 1a It is strongly identified on the mounting shaft 3a of the fly bar 3 on the front side and the front side of the front side.
- the die-type fly scatter 1 compresses the taper member 2 even if it tries to move in the direction of the downward spread of the taper, and the glaze 3 a In close contact with.
- the mounting hole 1a is a tapered hole and the taper member 2 is used when removing the reel type fly scatter 1 from the flyover 3, the cutting load is almost not applied to the bolt 4.
- the Taber Hayashi 2 can be easily removed by pressing it into the strong fe! Because of its shape.
- the keyway 1c and the key 3c for detent may not necessarily be provided.
- the scroll type slider and mounting method according to the present invention is a scroll type fly scatter because the mounting hole for mounting on the fly bar is a downwardly expanding tapered hole.
- the mounting strength is greatly increased and the roundness is accurate and there is no chattering, which improves the cutting accuracy, high speed, heavy
- Its practical value is great because it enables cutting, the cutting efficiency is almost the same as the performance of the integrated fly scatterer, and it is extremely easy to install and remove.
