The lining drawing device is suitable for drawing not only thru hole linings but also blind hole linings, and thus has wide applied range.
Description
Technical field
The utility model relates to a kind of hand disassembly instrument that is out of shape part that has, and specifically is meant a kind of lining drawbench.
Background technology
The Chinese patent notification number: CN 200984726Y, the day for announcing: on December 5th, 2007, utility model title " blind hole lining puller ", it comprises axle sleeve, pull bar, drawhead and handle.The drawing section of axle sleeve there is not axis direction to have the bar shaped groove, and an end of pull bar is located in the axle sleeve in the screwfeed mode, and drawhead is fixed on the external part of pull bar, and handle is installed on the drawhead.During use, axle sleeve drawing section is stretched in the lining endoporus, turning handle, pull bar push away the section of pulling out can make the locking of axle sleeve and lining with the axle sleeve distending, at this moment is pulled outwardly handle, lining will be pulled out.Use more convenient, be difficult for infringement workpiece and lining, but also need other to pull out axle sleeve and lining by the employing instrument after this puller locking, operate cumbersome, and the faying face of axle sleeve and lining relies on frictional force locking, because the frictional force of locking is limited, axle sleeve skids in drawing easily, and result of use is desirable not enough.
Summary of the invention
The purpose of this utility model is that to overcome existing lining puller locking frictional force less, pulls out lining inconvenience, and the defective of troublesome poeration and deficiency provide a kind of coupling mechanism force big, pull out fast, the easy to operate lining drawbench of lining.It is simple in structure, and cost of manufacture is low, does not damage parts, and result of use is good.
For achieving the above object, technical solution of the present utility model is: the lining drawbench, comprise expansion sleeve, dilating screw and nut, dilating screw penetrates in the endoporus of expansion sleeve, the outer surface of expansion side one end is provided with ring-type awl sword on the described expansion sleeve, the cutting edge of described annular awl sword is towards the other end of expansion sleeve, the outer surface of the expansion sleeve other end is provided with screw thread and is combined with the drawing nut, be set with the drawing stay pipe in the outside of expansion sleeve, the internal diameter of drawing stay pipe is greater than by the external diameter of drawing lining, and an end of drawing stay pipe withstands on the parts of lining outside, and the other end withstands on the end face of drawing nut.
The cutting edge of described ring-type awl sword is provided with chamfering.
Described drawing stay pipe is provided with peep hole or groove.
Compared with prior art, the beneficial effects of the utility model are: 1. pulling capacity is big.Because the inner hole wall of the awl of the ring-type on expansion sleeve outer surface sword incision lining, can block lining securely, changed the fastening means that original puller relies on the frictional force Locking bushing, stopped the phenomenon that expansion sleeve skids in lining, its pulling capacity is obviously improved.2. easy to operate.Be manufactured with screw thread and be combined with the drawing nut on the outer surface of expansion sleeve opposite side, drawing nut roof pressure can drive expansion sleeve like a cork lining is pulled out by screwing the drawing nut on the drawing stay pipe, and is extremely easy to use.3. simple in structure, volume is little, and cost of manufacture is extremely low, not only is suitable for drawing through hole lining, also is suitable for drawing blind hole lining, applied range.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: expansion sleeve 1, dilating screw 2, nut 3, annular awl sword 4, screw thread 5, drawing nut 6 is drawn stay pipe 7 over to one's side, chamfering 8, peep hole or groove 9.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is described in further detail.
Referring to Fig. 1, lining drawbench of the present utility model, comprise expansion sleeve 1, dilating screw 2 and nut 3 are provided with the little inner conical surface of mouthful imperial palace in the endoporus of expansion sleeve 1 one ends, and have many openings in tube wall upper edge axis direction symmetry, be dilatation joint, make it to become the expansion side, an end of dilating screw 2 is provided with screw thread, and being combined with nut 3, the other end of dilating screw 2 is provided with and the corresponding tapering of expansion sleeve 1 inner conical surface.Dilating screw 2 penetrates in the endoporus of expansion sleeve 1, the outer surface of expansion side one end is provided with ring-type awl sword 4 on the described expansion sleeve 1, the microcephaly of ring-type awl sword 4 is towards expansion side one end of expansion sleeve 1, the cutting edge of described annular awl sword 4 is the other end of major part towards expansion sleeve 1, the outer surface of expansion sleeve 1 other end is provided with screw thread 5 and is combined with drawing nut 6, be set with drawing stay pipe 7 in the outside of expansion sleeve 1, the internal diameter of drawing stay pipe 7 is greater than by the external diameter of drawing lining, one end of drawing stay pipe 7 withstands on the parts of lining outside, and the other end withstands on the end face of drawing nut 6.Described drawing stay pipe 7 is provided with peep hole or groove 9, also drawing stay pipe 7 can be made the hollow pipe support of opening of external wall, so that the concentric situation when observing drawing stay pipe 7 location, avoids when drawing drawing stay pipe 7 roof pressures on lining.
During use, insert dilating screw 2 from inner conical surface one side of expansion sleeve 1, and on dilating screw 2, screw on nut 3, drawing nut 6 is screwed on the screw thread 5 of expansion sleeve 1, also can overlap upper gasket, put drawing stay pipe 7 then, expansion sleeve 1 is inserted in the lining that needs drawing, drawing stay pipe 7 correspondences are withstood on the parts of lining outside, after very good, screw nut 3 earlier, dilating screw 2 is shunk back in expansion sleeve 1, tapering on it is opened the expansion side stay of expansion sleeve 1, makes in the ring-type awl sword 4 incision lining inwalls on the expansion side external surface.For the cutting edge that prevents ring-type awl sword 4 is too sharp, cause when drawing, fractureing, cutting edge that can described ring-type awl sword 4 is provided with chamfering 8.After screwing nut 3, screw drawing nut 6 again, under the jacking of drawing stay pipe 7, expansion sleeve 1 and dilating screw 2 integral body move in drawing stay pipe 7, because ring-type awl sword 4 snaps in the lining, move outside parts so drive lining, until pulling out lining.Because the internal diameter of drawing stay pipe 7 is greater than the external diameter of lining, the lining that is gone out by drawing directly enters in the endoporus of drawing stay pipe 7, at this moment unclamps nut 3, removes the expansive force of 2 pairs of linings of dilating screw, can take out lining.
