Description of the invention (1) The present invention is based on a kind of expansion and contraction shaft, that is, it is used in the manufacture or processing of gold sheet, paper, plastic ® Film and other equipment, when rolling these sheet materials into a simple shape, it is necessary to fix the ring-shaped or chrysanthemum-shaped members such as the heart in advance on the roll _ outer peripheral surface or in order to make such roll materials The guides and other simple or simple members used to align the thin rolls to facilitate the rolling into a tube; or the separation discs (separarter dis〇 etc.) that cut the rolled material such as smilax into multiple strips and take up Shaped member; or when the ring-shaped or cylindrical member such as a slitter of a strip is fixed or detached; it is also about to be assembled on the outer peripheral surface of the rotating shaft and the simple or simple member is fixed to the rotating shaft For the purpose of making two expansion and contraction car: Specially lend the ring-shaped or simple members that are inseparably installed on the outer peripheral surface of the rotating shaft by a long-shaped pressing member (lug) that is inscribed on the outer peripheral surface of the rotating shaft The inner circumferential surface is pushed radially outwards to hold the Chen-shaped or cylindrical member In the equipment for manufacturing or processing sheet materials such as gold foil, paper, and plastic film according to the conventional equipment for manufacturing or processing gold sheet, paper, plastic sleeping film, etc. The cores of some roll products are fixed on the rotating shaft, in addition, they are used to align the edges of the materials of the other rolls to facilitate the guide device for rolling into a tube, or to cut the material into a plurality of strips. The separating disc of the coil or the cutter of the strip shear also needs to be fixed on the rotating shaft. The cutter or the dividing disc of the upper slitting machine is inserted with a spacer in the middle, which is tight _For the way of fixing the pan at the end, when re-assembling the cutter or the partition disc, the cutter or the partition disc must be folded one by one from the rotating shaft and reassembled, so the hand mine is cumbersome * To solve this one As for the topic, there is now an air shaft type expansion and contraction shaft that is used by people.

Description of the invention (2) This type of gas shaft expansion and contraction shaft Su is made up of hollow pyrene-shaped skeletons. Inside the hollow of this shaft, hoses filled with ® shrink air are inserted along the axis direction. This hose has a structure that expands and shrinks according to the injected air house In addition, the axial direction and the circumferential direction of the outside surface of the hollow cylindrical shape of the car are separated from each other at a certain time. There are many divided into short sections along the axis direction. Several long holes are arranged and short holes are arranged in each hole. A truncated push piece (lug). These teeth push pieces arranged on the surface of the outside of the sickle shaft are expanded and contracted by the air pressure of the hose inserted inside the hollow of the expansion shaft It is pushed freely, and the hose is squeezed by the chlorinated abdominal pressure hose to push the cranes out of the KM, and the heart or ring-shaped members such as the heart or ring that are inscribed on the outer surface of the expansion and contraction shaft are inscribed. The inner circumference is pushed outwards radially, and then the Chen-shaped or commercial-shaped members are held at a predetermined position on the outer circumferential surface of the Niangao axis. However / this conventional pneumatic shaft expansion and contraction _ has the following problems: (1) Because the shaft for inserting the air hose is hollow inside and the outer circumference of the hollow shaft is provided with a large length? L is for assembly push M (lug), so the friction of the shaft is large, so it cannot be used for long shafts that require strength; Printed by the Ministry of Economic Affairs, Central Building, Consumer Labor Cooperative (2) Separating ring for the outboard shaft Wait for S! To be placed near the end of the thrust piece for expansion operation. The partition is likely to produce lateral displacement, causing dimensional variation; (3) Because most of the short cuts push the ffi piece to contact the air inside the shaft When the soft If is on the outside, it repeatedly expands and shrinks, so the hose with a rubber waist crack is extremely vulnerable to damage, and even cracks may occur. At the same time, when the air in the hose is released, the hose is easily deformed, resulting in an accident in which the pressing piece is detached from the inside of the hollow shaft. When such an accident occurs, due to the internal structure of the image, it can not be repeated on this paper.

Description of invention ί: 3) Except for on-site baht, it must be sent to a fixed manufacturing workshop for repair, so Scratch is inconvenient; U) In addition to the above question, because the air hose needs to use low ® deflated air, so in the case of the external axis of the shaft subjected to large external forces, the problem of cabinet displacement will occur ; (5) In addition, there is still insufficient retention of the winding center of the paper and the film and the loss of distortion occurs. The present invention is based on the problems and defects of the above-mentioned conventional technology, and its purpose is to provide a hollow cavity that does not need to form the inside of the shaft, which can prevent the reduction of the 11th nature of the expansion and contraction shaft, so that The long axis of the shaft fits the center of the shaft so that it does not distort, and it can prevent the trouble caused by the air leakage from time to time, and it can also prevent the transverse displacement of the ring or cylindrical member. , The ring-shaped or cylindrical member is correctly and firmly held at the gingival improved shaft of the mine shaft. In order to achieve the above purpose, the present invention provides an outer surface of the curve with access α; and along the axis direction is provided with two slanting surfaces inclined with the bottom of the quotient and the two thin surfaces and the bottom of the symmetrical angle formed Fear strip groove; fitted at the above-mentioned entrance and exit of the shaft and can be freely formed by the wavy ridges at the above-mentioned entrance and exit of the shaft and has a tilt angle smaller than the included angle. The flow channel provided at the end of the shaft to the bottom of the above-mentioned groove, and when the streamer is introduced through this channel between the bottom of Xiao and the bottom surface of the inclined surface of the bottom of the long-sliding pressing member, the pressing member is forced to It is shifted within the distance formed by the difference between the above-mentioned angle and the inclination angle of the bottom inclined flange surface. When releasing the fluid, it is constituted as a special expansion and contraction by the means of the bottom inclined flange surface itself to retreat by itself. axis.

When the pressing member 3 is subjected to flow scraping, its first flat 3a will protrude from the entrance and exit of the thin 2 toward the outer peripheral surface side of the shaft 1, so it pushes on the outer peripheral surface of the car 1, such as the winding center, etc. The inner peripheral surface of the shape or cylindrical member a, so that it is fixedly fixed on the shaft 1. The long strip pushes the sleeper 3 before the left side of the pin 3a On the right, the maple surface is formed into a parallel straight line, and the two left and right inverted surfaces of the rear caliper are formed to push backward and gradually become the bottom inclined flange surface 3b. This bottom inclined flange surface 3b can be formed by the long pressing member 3 A jagged structure can also be a structure in which different materials are connected to each other to form a jellyfish. However, the bottom inclined surface 3b must be made of a kneading material E, so that it is subjected to a pressurized fluid and undergoes a definitive deformation. It forms a tight joint with the inclined locking surface 2a of the upper ditch 2. When the bottom inclined flange surface 3b is elastically deformed and the above inclined locking surface 2a is in close contact, the Di can seal the rear sickle acting on the pusher 3 The bottom of the inclined surface 3b is behind the end surface 3e, to prevent the fluid from leaking. The strip pushes the K piece 3 and the rear part of the cumulus is formed by the bottom inclined surface 3b to form a symmetrical platform shape, but as in 3ffl (A ), The inclination angles A of both ends of the platform-shaped bottom edge of the bottom inclined flange surface 3b are slightly smaller than the angle of inclination B of the platform shape of the inclined locking surface 2a of the groove 2 described above. Therefore, when the pressure of the bar pushing member 3 is affected by the pressure, it can shift within the distance between the difference between the inclination angle B of the bottom two surfaces of the groove 2 and the inclination angle B of the bottom inclined flange surface 3 b . -8- (please read the $ item on the back and then fill in this page) This paper standard is universal Chinese Pujia (CNS) A4 specification (210X297mm) Central Bureau of Standards-Ministry of Economic Affairs-Industrial and Consumer Cooperative Printed A7 _B7 ^ _ V. Description of the invention (6) Make its leading end M3 a infest at the entrance and exit of the ditch 2. When the stream is released and the pressure is reduced, the tip 3a is retracted into the groove 2. At this time, there is an interval between the front of the bottom inclined surface 3b and the inclined locking surface 2a of the groove 2 except for the L, but the bottom The rear part of the inclined flange surface 3b is in close contact with the inclined locking surface 2a of the groove 2, so that the leakage of the stream is blocked. Conversely, when the flow is introduced to increase the pressure, the bottom inclined flange surface 3b is due to the eagle stress The strong force should be connected to the two indium inclined locking surfaces 2a of the groove 2 to maintain the sealed shape. That is, when the bottom of each ditch 2 is introduced into an oblique series which can tilt the bottom of the long itching pushing member 3, when the face 3b is pushed toward the entrance and exit of the ditch 2 after the end surface 3c, the long pushing member 3 protrudes to its First, M3 a is in contact with the inner surface of the Chen-shaped or cylindrical material a to keep the component a in position (as shown in the third circle B); when the discharge is released (the pressure is released), the bottom is tilted. The surface 3bdi is sullen by its own nature, so that the long pressing member 3 is unwound from the outer surface of the shrinking shaft 1 to the original position (as shown in No. 3 圔 A). Oil, water or air. As shown in Nos. 1 and 2, the bottoms of the grooves 2 of the expansion and contraction shaft 1 are formed with flow bun introduction grooves 4a along the direction of the grooves 2 (longitudinal), and the fluid introduction grooves 4a at the bottom of each groove 2a The fluid introduction ports 4b of the americium at one end of the fluid passage 4 are respectively connected. The flow inlets 4b of one of the above-mentioned flow channels 4 fall down, and the radial divergence is formed by the central part of the expansion and contraction 1, and the flow of this divergence »The inlet 4b is connected to the bottom of each trench 2 The fluid is introduced into the groove 4a; the other end of the flow channel 4 extends to one end of the expanding shaft 1 and is connected to the unshown streamer pipe. The unrecognized flow mulberry pipeline is connected to the pressure storage tank via a non-illustrated three-way valve, for example.

Description of the invention i: 7) The shrinkage of the shrinking shaft 1 is larger and smaller. The flow at the bottom of each channel 2 "the introduction channel 4a is connected to the flow channel 4b and the flow channel 4 so that the flow channel enclosed in the bottom of each channel 2 is the same as the flow channel in the channel 4a. Force, so the same pressure can be used to push the bottom of the elongated pressing member 3 in each of the pots 2 and the inclined surface 3D and then the end surface 3 c times to illustrate the effect of the upper embodiment of the invention on the following: Or the a-shaped member a is installed on the designated part of the 1 H plane of the tearing car. At this time, all the elongated pressing members 3a of the expansion and contraction are submerged into the groove 2, that is, they do not protrude on the outer surface of the expansion and contraction barn 1, such as the third A. The inner diameter of the a-shaped or cylindrical member a installed in the expansion car 1 is slightly larger than the outer diameter of the shaft 1, and the erbium 3a of the tip of each long pressing member 3 does not protrude from the outer peripheral surface of the shaft 1 Therefore, it is possible to arbitrarily make it slide and position it at a predetermined part of the knitting shaft 1. After installing (positioning) the cylindrical member a on the predetermined part of the shaft 1, start the unrepresented flow-in pressure pump or air pressure eaves arranged outside the knot shaft 1. When the pressure booster pump or air compressor starts, the flow mule flows from the uncirculated pressure germanium to the flow mule pipeline, and is then scraped to the fluid passage 4 of the expansion and contraction shaft 1, and then passes through the radial divergence. Each flow inlet 4b flows into the flow guide channel 4a at the bottom of each groove 2. When the stream flows into the fluid guiding ditch 4a at the bottom of each ditch 2, the long side of each ditch 2 pushes the bottom surface of the piece 3 inclined 3b after the blanched surface 3c is subjected to the plaque force of the stream The uniform pressing force forces the long pressing pieces 3 to face the groove -10- This paper is suitable for the Chinese national standard (CNS> A4 regulation (2I0X297 mm) | ~ * 1-Iί 4 ------ booking- ----- 彳 _!

Invention description (8) The entrance and exit of 2 slipped It is closely connected to the holding surface of the thin 2, that is, the bottom of the platform-shaped inclined flange surface 3 b. The two ends of the planer are in close contact with the two ends of the rear of the platform-shaped inclined locking surface 2a of the groove 2. Since the inclination angle B of the front of the inclined locking surface 2a is larger than the inclination angle A of the front of the upper inclined bottom flange surface 3b, the front americium before the bottom inclined flange surface 3b and the inclined locking surface 2a There is an intermittent L between the sides (refer to the third circle A), so when the rear surface 3c is pushed by the streamer, a convex arc shape begins to occur in the central residence of the end surface 3c after the bottom oblique flange surface 3b , So that the front part of the bottom inclined flange surface 3b is in close contact with the front part of the inclined locking surface 2a. In addition, when the central arc of the bottom inclined flange surface 3b and the crimson surface 3c begins to undergo a convex arc deformation, The elastically deformed bottom sloping flange surface 3b pushes the entire pressing member 3 to the entrance and exit side of the groove 2 as a result of the elastic deformation of the bottom, resulting in the tip end 3a of the push member 3 protruding outward from the entrance and exit of the groove 2 And when it comes into contact with the inner surface of the chen-like or chrysanthemum member a installed on the outer surface of the expansion and contraction shaft 1. When the secondary mine also transfers the pressure pump to increase the flow force, the bottom is inclined before the flange surface 3b The partial injury is deformed and is completely in close contact with the erbium in front of the inclined locking surface 2a, and the inclination angle A of the front surface of the slope to the bottom inclined flange surface 3b is the same as the inclination angle B of the front M of the inclined locking surface 2a Shaped goose (refer to the third circle B). In this state, it is possible to reliably prevent the pus from being pulled out between the bottom oblique editing surface 3b and the oblique locking surface 2a. At the same time, the above-mentioned groove 2 protrudes outward Should I push the tip M 3a of the piece 3 to install the outer surface of the expansion and contraction shaft 1 The inner peripheral surface of the cut-out or crown-shaped member a, which is fixed on the axis 1-11-This paper scale is applicable to the Chinese National Standard (CNS) A4 specification (2 〖0X297mm) —ΊΙ—ίΗ-- ---- Subscribe ------ 1 — (Pray first read the notes on the back and fill out this page) A7 _ B7_.

Description of the invention (9) Since each long cannula® piece 3 has an axial ffi located near the full length of the ore shaft 1 and is pushed uniformly and radially outward from the inner center of Lai 1, it is possible to exert a firm tightening of the cylindrical member a Function. It is completely different from the conventional short-cut pusher that used splitting. The end of the pusher sleeps on the end of the cylindrical member a to cause the lateral displacement of the cylindrical member a. Problem 9 From the above It can be seen from the description that the expansion and contraction of the present invention does not have to be as known, in order to hammer the hose in the shaft, the shaft must be formed into a hollow. According to Di Shuowei, the central part of it does not undergo deflection, which can prevent the lack of rotation in the heart state due to the central part of the change during rotation. In addition, there is no need to introduce air into the hose as the conventional ones. Therefore, there is no place where air is pulled out due to the rupture of the hose, and the period of the cylindrical member is tightly fixed by pushing the long pressing member by flow pressure At the bottom, the inclined surface of the push member is deformed thinly and closely adheres to the inclined inclined locking fennel, so even the use of high-force fluids can indeed prevent the leakage of the streamer. In addition, since the pressing member is formed into a fearful shape along the axis direction of the expansion and contraction axis, it is possible to avoid that when the cylindrical member is pushed by a plurality of pressing members divided into short sections as is conventionally known, each pressing member If the end of the cylindrical member touches the end of the cylindrical member, the lateral displacement of the simple member will not be able to correctly fix the cylindrical member to the stern. As mentioned above, in this case, due to the use of a substantially solid expansion and contraction shaft, the shaft itself has greater strength, does not deflect, and can be made longer, while being pushed by a long bar arranged along the direction of the center The cylindrical member, so it can be used. -12- This paper is used in China National Standard (CNS) Α4 wash grid (210X297 mm) I —-;-— ---- *-^ ------ Order ------ Line '' (please read note f on the back of Jing Jing before filling in this page) Printed by the Ministry of Economic Affairs of the Central Bureau of Consumers and Workers η.
